26.06.2020

Throughout the development of mankind, certain inventions have regularly appeared, designed to simplify and improve people's lives. Technological progress never stands still, so the development of the scientific sphere is a completely natural and logical process.

Not so long ago, such a device as an ultrasonic bath gained popularity among consumers. Almost any owner can create this mechanism with his own hands, it is only important to have a certain list of materials available and strictly follow the manufacturing technology. This product is used mainly to clean certain objects, while the work is based not on standard methods, but on the use of such a relatively new phenomenon as ultrasound. Therefore, what is an ultrasonic cleaning bath, and how it functions, will be discussed further.

Principle of operation

From the name of this device it becomes clear what underlies its functioning. Ultrasound is a kind of vibration, the frequency of which exceeds 18 kHz. The liquid that is in such a bath is filled with a large number of bubbles, which burst under the influence of high pressure, creating an effect called cavitation.

The principle of operation is as follows: an object requiring cleaning is immersed inside the tank with a solution. After starting the device, the bubbles, bursting, act on the contaminated mechanism and remove plaque from it. This method allows you to get rid of dirt even in the most inaccessible parts of the product for manual processing, without violating its structural integrity.

What does an ultrasonic cleaning bath consist of?

Outwardly, this device is not very large, about 1 liter (there are samples of a larger size, containing 5, 10 or more liters), made, as a rule, of stainless steel. This is quite enough to process a variety of devices and mechanisms.

The design of such a product includes 3 main elements:

The emitter, the main purpose of which is to convert electrical vibrations created by ultrasound into mechanical vibrations, which are subsequently transferred to the bath liquid through its walls.
A generator that serves as a source of vibration.
A heating element. Its main function is to make the ultrasonic bath liquid have a constant temperature of 70°C. It is worth noting that sometimes such a structural component may not be included in the design of the device, but its presence definitely contributes to better cleaning.

Scope of ultrasonic baths

This method of removing dirt is much more effective than traditional options. To clean a wide variety of products, an ultrasonic bath is actively used in many areas:

in medicine, its use allows thorough sterilization of surgical and laboratory instruments;
in the engineering field, an ultrasonic bath plays the role of a unit that removes contaminants from pipes and other large parts after they have been polished and polished;
these devices are widely used in jewelry, when periodically there is a need to clean jewelry that has lost its presentable appearance;
employees of the printing house use an ultrasonic bath primarily to wash the structural parts of printers and other devices responsible for printing;
the use of this multifunctional device also helps to clean silicon and quartz wafers, which form the basis of electronic production;
motorists know firsthand about the need to clean the structural components of the vehicle, such as nozzles, filters, injectors, etc.

The main advantages of ultrasonic baths

If we compare such a system with other devices, then we cannot fail to note a number of its undeniable advantages, including:

An ultrasonic bathtub is a very easy-to-use product. For its functioning, it is only necessary to fill the container with the necessary solution, and the cleaning process can begin.
Any contamination even in the most inaccessible parts of an object can be removed with its help without any problems.
High performance indicators. The ideal result of cleaning a thing can be achieved by holding it inside the bath in just 2-3 minutes.
After the end of the procedure, no mechanical damage will appear on the surface of the product, since its processing takes place without the use of any aggressive means.

Main selection criteria

In order for the purchased ultrasonic bath to work as efficiently as possible, you need to familiarize yourself with some factors that affect the quality of its work.

As mentioned earlier, the presence in its design is welcome, since the cleaning time in this case is significantly reduced, and the positive result is more obvious. However, it should be noted that if the ultrasonic bath liquid contains a disinfectant solution, then it is not necessary to use additional energy to increase the temperature.

In addition, it is important to immediately determine which items will be cleaned, since the capacity of the device must correspond to the volume of products immersed in it.

Next, a few words should be said about how to make a similar device for removing dirt from automobile nozzles. It is these parts of the vehicle that most often require cleaning, so the specifics of the work must be described in more detail.

Materials for the manufacture of ultrasonic bath for nozzles

Every car owner knows that for the stable operation of the engine it is very important to keep all its components in order. When an ultrasonic bath is used, it is safe to talk about the safety of the vehicle. However, such work performed at any service station will be very expensive. Therefore, you should figure out what ultrasonic baths for nozzles are in order to make such a device yourself.

But first you need to decide on the list of materials required for self-assembly. These include:

A container that will serve as the basis. She can be any not too large basin.
Washing machine with ultrasonic function. You can buy such a device in almost any household supply store.
The simplest washing powder that does not have impurities and additional properties like a bleaching effect.
Hot water.
If available - a special spray for cleaning nozzles. However, it is quite possible to do without it.

Self-made ultrasonic bath for nozzles

The process of creating such a unit does not carry any complexity. To begin with, you should take a clean basin and draw hot water into it, in which you subsequently need to dilute the washing powder in approximately the same proportion as for washing. After that, the nozzles that need to be cleaned should be immersed in the liquid and lowered. Its operation time is about 30 minutes. At the same time, it is important to remember that the water in the basin should be changed until the smell of gasoline completely disappears during the operation of the device.

After the unpleasant odor is no longer felt, the nozzles should be placed directly in the center of the device, which will speed up the cleaning process. 6 hours is the standard time for which the bath should operate. will completely remove dirt and oil residues from car parts. In addition, this cleaning option will enable the owner to save a significant part of the financial resources.

A set of materials for mounting an ultrasonic bath

In order to construct such a device with your own hands, it is important to correctly understand the principle of its operation, otherwise complex manipulations will not lead to anything good. Having studied the features of the functioning of such a mechanism as an ultrasonic bath, you can assemble it with your own hands, having the following list of materials available:

plastic or glass tube;
a round magnet (such a detail can be found in many old speakers);
coil;
liquid intended for ultrasonic bath;
porcelain container;
pulse-based transformer;
pump;
steel frame.

After all the parts are prepared, assembly can begin.

Manufacturing process of ultrasonic cleaning bath

As mentioned earlier, such work must take place in strict accordance with a pre-prepared plan, so that the end result is positive. The diagram of an ultrasonic bath, which is displayed below, will help to understand the device of a home-made device.

The installation process begins with the fact that the coil must be wound on a prepared plastic or glass tube. A magnet should be placed on the remaining section of the rod. The resulting device is nothing more than a transducer called magnetostrictive.

All the following actions must be carried out according to the following algorithm:

A porcelain vessel should be installed in a steel frame.
After that, the bottom of this part should be equipped with a hole where the already manufactured converter should be placed.
Then, in the design of the vessel, it is required to build branch pipes. These elements are designed so that liquid enters through them and subsequently drains. In the event that it is planned to design a large bath, it would be useful to take care of installing a pump that accelerates the flow of the solution.
At the end of the installation, an impulsive transformer is installed, the main function of which is to increase the voltage. For these purposes, any mechanism of this kind, taken from a TV or computer, is suitable.

The work is completed by checking the functioning of the ultrasonic bath. If the assembly process was carried out correctly, then the operation of such a device will save a significant part of the budget and will make it possible to thoroughly and efficiently clean all the necessary parts.

An ultrasonic bath is a special equipment that allows you to clean fragile items, jewelry, electronic parts, microcircuits, etc. from heavy dirt and plaque. The procedure is carried out by influencing the surface of ultrasonic waves in the range from 18 to 120 kHz.

They create cavitation, in which millions of tiny bubbles are formed, acting on the parts together with the active detergent and cleaning it from solid deposits and contaminants. Before buying, many are interested, which ultrasonic bath is better and what parameters should be considered when choosing.

Benefits of Ultrasonic Cleaning and Applications of Ultrasonic Baths

Let us dwell a little on the possibilities and advantages of this method. The fields of application of ultrasonic baths are extensive. They are used in the electronics industry for washing printed circuit boards, cleaning quartz and silicon wafers, which is in demand when repairing mobile phones, tablets and other gadgets.

In addition to this area, ultrasonic baths are used for cleaning jewelry, in the medical industry for sterilizing instruments, for repairing office equipment, in the chemical industry, and so on. Such a method has the following advantages:

Gentle and effective cleaning without damage in the form of scratches.
The process takes place without the use of organic solvents.
Impact on hard-to-reach areas - pores, cavities and holes.
Save time on cleaning as it only takes minutes.

Which ultrasonic bath to choose?

Our catalog contains many varieties of such equipment with various parameters. You can, the characteristics of which will be most suitable for your purposes. Consider the following factors to select the best equipment for your business:

Wave frequency. There is no direct relationship between this parameter and cleaning efficiency. For each frequency level, there is an extreme limit to the degree of purification at a certain level of microscopic bubbles. The higher it is, the smaller the bubbles, respectively, they remove smaller particles of dirt. For example, at a frequency of 100 kHz, particles up to 1 micron are effectively removed, so this equipment is used to sterilize medical instruments. To clean the boards of smartphones and gadgets, choose best ultrasonic baths from our catalog with frequencies up to 50 kHz.
Tank size. When choosing a device, you need to consider the capacity of the basket in which you will place your products. It is recommended to buy an ultrasonic bath that has a margin, as objects to be cleaned must not be placed on the bottom of the bath. Cleaning occurs only in the basket.
Heating. The presence of this function will allow you to carry out procedures faster and more efficiently, since most solutions work best at a temperature of 50-60 degrees Celsius.
The presence of a timer. An important element that will allow you to start the cleaning process and go about your business.

In our catalog there are many devices with different parameters from leading manufacturers: Codyson, YaXun, Skymen. Fulfill ultrasonic bath comparison according to the characteristics presented in order to purchase the appropriate option.

Content

To clean small items (parts, circuit boards, jewelry, tools), you need a device consisting of a tank, emitter and electronic control unit. This is a washing ultrasonic bath, which is an indispensable assistant for electronics engineers, car repairmen, and jewelers. If the job requires washing small parts or objects, you need to buy an ultrasonic cleaner or make your own.

What is an ultrasonic bath

Ultrasound is sound in a higher range than the human ear can perceive. Its use in modern science has led to a number of fantastic discoveries. One of them is an ultrasonic bath that magically turns dirty things into clean ones. This happens as a result of the cavitation process - the formation and collapse of many small air bubbles on the treated surface. The microexplosion of each balloon is strong, the bubble is able to tear off a particle of dirt from a part or product even in the most inaccessible places for physical impact.

The main details of the device are a container with a volume of 0.5 to 30 liters and an emitter for an ultrasonic bath operating in the range of 20–40 kHz. It is located under the bottom of the working tank and is electronically controlled. The principle of operation of the unit is simple: fill the bathtub with water, alcohol, other active chemical liquid, immerse an object in need of cleaning into it, turn on the emitter for only 2-3 minutes. You won't believe your eyes: as a result of ultrasonic vibrations, the part will become cleaner than new.

What is needed for

The scope of the bath is wider than you might imagine. Larger ultrasonic units are used in enterprises for cleaning large parts, tools, workpieces. There are ultrasonic baths even for washing clothes, washing dishes, processing vegetables. An ultrasonic emitter is built into many models of modern washing machines. Household bathtubs are often bought to wash parts, circuit boards, nozzles and jewelry.

For cleaning nozzles

Nozzle - a mechanism that is an elementary valve, electromagnetic, which doses the supply and spray of fuel (it must do this as accurately as possible). Clogged nozzles are difficult to clean, but an ultrasonic bath does the job. If necessary, the injector with nozzles is removed and flushed with waves at a gentle frequency, repeating the procedure several times.

For phones

A phone that has fallen into water can be saved by washing the motherboard with ultrasound of a certain frequency. For such a procedure, technical services also use a household washing bath. The master will remove the board, remove parts from it that are harmful to contact with water (camera, speaker, microphone), lower it inside the bath, fill it with a special solution and turn on the device to operate at a given frequency. The board will be cleaned with air bubbles, the phone will be restored.

For washing parts

You can use an ultrasonic bath to clean optics, metal, and other hard parts from dirt, foreign components, traces of soldering or grinding. A device is used for cleaning components and parts of office equipment (great for washing printer heads, increases their service life). The ultrasonic bath of the master of jewelry production is very much appreciated. Even items that are heavily soiled during wear become absolutely clean after a few minutes of treatment.

Advantages

An ultrasonic cleaning option may be preferable to a mechanical one. Sometimes it becomes the only way to clean up a contaminated part with traces of corrosion. Here are the main benefits of using an ultrasonic bath:

Processing the laundered item does not take much time.
No physical effort is required to mechanically remove dirt and rust.
An excellent effect is achieved in the most inaccessible places (waves know no barriers).
Ultrasound cleans objects gently without leaving scratches or other flaws on the surface.
The procedure can replace not only washing, but also light polishing.

How to use

An obvious but extremely important recommendation: before using an ultrasonic bath, be sure to read the instructions for it! To clean a part or product from dirt, traces of corrosion, limescale, tap, well, distilled water, alcohol, soapy water, and some types of solvents are used. During the operation of the bath, a buzzing sound is clearly heard, and many bubbles appear on the surface of the immersed objects. Your maintenance steps are simple:

Open the lid and fill the working container with the selected liquid.
Place parts or products so that they are completely covered with water.
Check the fluid level, it should not rise above a special mark.
Close the lid, connect the device to a source of electrical energy.
Press the "start" button, in most bath models, the standard operating time will be 180 seconds.
If necessary, turn on the device again. For uniform cleaning, the parts inside the bath must be turned over.
If required, you can start by increasing the time or range of the ultrasonic transducer.
When the process is completed, unplug the bath from the network, drain the water. Do not forget to dry the container, and then send the device to storage.
Treat the device with care, repairing an ultrasonic bath is troublesome and not always possible.

Do-it-yourself ultrasonic bath

Based on their own needs, skilled craftsmen often make their own cleaning bath. On the Internet pages of their blogs and video channels, they generously share their schemes and best practices. Possessing elementary skills in working with a soldering iron, you can make your own board - the brain center of a cleaning device, assemble an electrical circuit according to the scheme, including an emitter in it. So you get an ultrasonic bath that meets your needs. Here's what you need for this:

a board made according to a proven scheme;
light stainless steel container (saucepan, bowl, basin) with a capacity of 0.5-1 l;
stand for the container (you can use a piece of plastic sewer pipe);
12 volt power supply;
ferrite rod;
emitter of ultrasonic waves;
epoxy glue for mounting the emitter.

In order for ultrasonic waves to pass into the container, glue the emitter to the bowl exactly in the center, using epoxy glue for this. A ferrite core is needed to make a choke. Wind two dozen turns of copper wire (1 mm thick) on it. According to the scheme, assemble the electronic and electrical parts of the device. Install the structure on the stand, strengthening the electronic "stuffing" inside. Test your homemade bath with chocolate foil. Under the action of ultrasound, the foil in the bath is destroyed literally before our eyes.

Ultrasonic bath liquid

Distilled water is the best liquid for gentle treatment of objects. But in the presence of severe pollution, or when a quick result is needed, active additives and even aggressive chemical compounds are used. To clean silver, gold, optics, add up to 10% window cleaner to the water. Boards of telephones that have been in the water are "bathed" in ethyl alcohol or "galosh" gasoline. Each master has his favorite recipe, any option is a subject of controversy and personal preferences.

It is important to understand that although flammable liquids are used in ultrasonic baths, they are dangerous. When the ultrasonic emitter is operating, the unit may have an unsafe temperature, and vapors of solvents, gasoline, alcohol, when working without an extractor hood, are concentrated near the hot device. Therefore, manufacturers are categorically not recommended to take combustible mixtures as a working solution. This rule is very often violated by masters. Be careful!

Repair

Disassemble the non-working bath, check the contacts and connections, call the details. If the ultrasonic emitter fails, it must be replaced. In this case, the cost of repair can be comparable to the purchase of a new device. If the ultrasonic bath is under warranty, the case cannot be opened, look for a warranty workshop that produces devices of this brand, and entrust the repair to professionals.

How to choose an ultrasonic bath

If homemade appliances are not to your liking, and you decide to buy an ultrasonic bath for home use, you have an important choice to make. In the catalogs of online stores you can find dozens of units of different volume, power, cost. Before ordering a wash bath, determine how large it should be. If you have to process small items, small parts, boards, a volume of up to one liter is enough. For automotive injectors, medical instruments, larger parts and assemblies, the capacity should be 1.5-2 liters.

Material of working capacity of the device – stainless steel. Only it allows ultrasonic waves to freely enter the liquid and act on the object being cleaned. It is better to take a unit with a deeper bowl than a shallow but wide one. However, consider the size of the items to be washed. They must be completely immersed in the bath. An oversized container may require more liquid, which is uneconomical.

When selling with delivery by mail, carefully read the technical characteristics of the device, ask questions to the seller. Since the operation of the device is difficult to assess "by eye" in a few seconds, you will not be able to check its full serviceability at the place of issue. Special promotions, discounts and sales on the Internet should be especially alert. If the bath is sold too cheaply, something is definitely wrong with it.

One of the most ancient methods of treatment with the help of climatotherapy is sun treatment: this technique allows you to get a pronounced positive result, which becomes perfectly noticeable after just a few first applications. The sun's rays, stimulating the protective functions of the skin and the whole body, activate all vital processes in the body, eliminating signs of inflammation and providing the production of vitamin D.

Thanks to this vitamin, it becomes possible to eliminate the insufficiency of the endocrine system to a greater extent, eliminate the negative manifestations of many organic lesions and prevent the aggravation of existing inflammatory processes in the body.

The concept of the method

Being one of the most active healing methods, heliotherapy is easy to perform and can be used both in treatment and for prevention.

Heliotherapy is an almost obligatory component in any resort scheme of therapeutic effects: two types of rays of the solar spectrum provide the most complete positive effect due to diversity. The combination of this method of treatment and other methods of influence allows you to get the most pronounced positive results, eliminating the symptoms of many diseases.

About the benefits and harms of sunbathing, see the video below:

Types of exposure using heliotherapy

Sunlight is divided into two spectrums, which differ both in the type of exposure and in the sensations that arise when using them. The division of the sun's rays into spectra is as follows:

infrared radiation- a type of radiation that penetrates the skin and leads to the expansion of blood vessels due to their significant expansion, which allows the absorbable effect on various tissues, to eliminate the manifestations of stagnation in the tissues. With the help of infrared radiation, there is a thermal effect that is felt by the skin;
ultraviolet radiation, which is not felt by the skin and has a positive effect on all processes occurring both in the skin and in adjacent tissues. Under the influence, there is an active production of melanin by skin cells, which is responsible for the resulting tan and gives the skin an attractive golden hue. Possessing maximum biological activity, ultraviolet radiation quickly eliminates the symptoms of many organic lesions, reduces the degree of manifestation of inflammatory processes and other pathological manifestations.

The combination of the two listed types of exposure to sunlight allows you to get the most pronounced positive results, reduce the manifestation of many diseases and carry out a preventive effect on the body.

Advantages and disadvantages

The main advantage of this method of physiotherapy should be considered the duration of the preservation of a positive result and ease of use, which makes it possible to prescribe this means of healing and prevention as an aid and as an independent method. Also, the advantages of heliotherapy include the possibility of its use by almost all categories of patients, a relatively small number of contraindications. It is also important to consider the possibility of obtaining a positive result from the sun's rays, both from their natural source and from an artificial source in a medical center.

The disadvantages include the need to observe increased accuracy in use by people with fair skin, with increased sensitivity to sunlight.

Indications for the use of sunbathing

The use of such a method of physiotherapy as heliotherapy is indicated in the following cases:

In the presence of dermatological lesions - long-term non-healing injuries, wounds, and skin lesions in the form and, depriving scrofulous. Also such skin ailments:
With poor performance of the musculoskeletal apparatus - a violation in the state of ligaments, muscles and tendons, negative changes in the cartilage tissue of the joints, bone tuberculosis;
With lesions of the gastrointestinal tract;
In inflammatory diseases of the female genital organs.

The listed indications for the use of heliotherapy can be supplemented with a metabolic disorder, negative changes in the condition of the skin (with its increased fat content or), as well as preventive goals to stimulate the immune system.

Contraindications

The use of this method, due to its high degree of activity, has a number of limitations for use, which should be taken into account when choosing a method of physiotherapy. The most important contraindications to the use of heliotherapy include diseases such as:

oncological lesions,
the presence of current inflammatory processes of any localization in the acute stage,
the presence of autoimmune diseases ().

It is also not recommended to use this procedure for diseases of the hematopoietic system and endocrine lesions. Feverish conditions should also be considered the reason for the refusal of heliotherapy due to the high activity of the procedure and the possibility of aggravating the manifestations of the current condition.

To obtain a pronounced positive effect when using heliotherapy, you must first undergo an examination and have an accurate diagnosis, which will allow the attending physician to draw up a scheme of exposure.

The control of the ongoing treatment will allow avoiding the likely negative consequences of using this method of treatment in the form of an increase in the existing symptoms, a deterioration in general well-being.

Preparation for the procedure

Before sunbathing, clothes should be removed from the treated area of the skin, cleaned and covered with a special compound to prevent burns and overheating.

How to take sunbathing with health benefits, the video below will tell:

How is it carried out

The algorithm for performing heliotherapy is simple, its application can be carried out both in conditions of sunbathing in natural conditions, and in specialized institutions offering physiotherapy services.

In specialized conditions

Such a method of exposure as heliotherapy is prescribed, in the presence of the above indications, and is carried out under the supervision of a doctor. However, knowledge of certain rules that allow you to increase the degree of effectiveness of the impact, makes it possible to prevent the aggravation of the current disease, to enhance the therapeutic effect. These include the following recommendations:

Stay in direct sunlight should not exceed two hours to avoid overheating.
The time spent under the sun during the day should correspond to solar rhythms when the sun shows moderate activity. This means that the most optimal from the point of view of the effectiveness of the impact is the morning time until 11 o'clock in the afternoon, when the sun's rays have not yet become too scorching, and after 16 o'clock - the sun then becomes soft again, does not have a sharp effect on the skin and is not able to cause her .
When in the open sun, you should cover your head with a light headdress: it is the head that receives the most powerful exposure to the rays, as a result of which drowsiness may occur, and.
The use of sunscreens will help to avoid deterioration of the skin condition, which, with prolonged exposure to ultraviolet radiation, quickly ages, dries excessively and.
After sunbathing, the use of moisturizers is recommended, which help to remove the negative effects of ultraviolet rays and maintain healthy skin.

These rules are easy to use, allow you to achieve pronounced positive results and reduce the likely negative effects of heliotherapy.

Application features

The use of the considered method of the physiotherapeutic method has a number of its specific features, which should be taken into account when prescribing and conducting heliotherapy. Before using it, it is recommended to check the reaction of the skin to the sun's rays, while the fact of the source of the sun's rays is not important - natural rays or those obtained using an artificial source.

To do this, it is necessary to carry out a short-term exposure of the skin to sunlight and trace the reaction to them: if skin rashes appear, and, as well as pronounced redness, the application of this procedure should be stopped. In case of minor negative manifestations when exposed to ultraviolet or ultraviolet light, it is possible to reduce the degree of intensity and duration of the effect, and it is also necessary to use special protective preparations that allow the use of heliotherapy even with increased skin sensitivity.

Before use, the skin must be cleaned of impurities in the form of dust, dirt, cosmetic residues in order to obtain the maximum amount of ultraviolet radiation and a positive result from the exposure. If an impact is made on a limited area of the skin, then it is left open and the skin is irradiated. When processing the entire surface of the skin, it is necessary to remove clothing and, after applying a special protective agent, irradiate the skin.

The duration of the effect may vary depending on the degree of damage and the tolerability of heliotherapy. After the end of exposure, you should rest for some time: it is preferable to remain in a horizontal position for 15-30 minutes, do not make sudden movements in order to avoid possible dizziness. The surface of the skin treated with sunlight is recommended to be treated with a special agent with a moisturizing effect in order to prevent possible dryness of the skin and reduce the risk of skin tightness, itching and burning.

Consequences and possible complications

The use of heliotherapy can contribute to the appearance of areas with hypersensitive skin, if the time of exposure to sunlight is exceeded. Strict adherence to the recommended dosage will allow you to get only a positive result from this kind of physiotherapeutic effect.

Recovery and care

After receiving sunbathing both locally and on the whole body, there is a possibility of the appearance of areas with severe hyperemia, and it is necessary to use products that soothe the skin and restore its natural state. You may also need anti-burn agents that reduce the manifestations of the negative effects of exposure to ultraviolet rays on the skin.

Also, for a longer preservation of the positive result of exposure to ultraviolet and infrared radiation, it is recommended to use a course of vitamin therapy (especially vitamin E, which will restore the skin after exposure to sunlight), moisturizers.

Hi all! Today my review is dedicated to the ultrasonic bath. Under the cut there will be tests, an autopsy (many photos) and in the comments you can suggest what else you can “soak” in it.

Go…

Order, payment, delivery - everything is already familiar to mysku readers and the most interesting thing here is the delivery time. The bathtub ordered in early January arrived in 24 days! PR is faster than ever!

A pimply bag with the contents of "gadgets" and a price of 5usd so that the customs sleep peacefully.

The box is wrinkled, but everything inside is intact. Bathtub with lid, standard Chinese plug (no adapter) and instructions in Chinese and broken English.

I made it a rule to open electrical appliances before plugging them into the network, and as it turned out - not in vain! A piece of solder walks inside the case (circled in red).

There are no non-solders, everything is holding, the board is traditionally stained with rosin.

The Chinese Quality Control Department allows this, so let's leave it as it is.

Tests…
I take the first available board from a burned-out energy-saving device, pour ordinary tap water into the bathtub. Turn on the network, select the mode (30 or 50) and time (1 on the display = 30 seconds) and start!

A minute later (the display was 2).

The bath washed off light dirt, but no more than that - the dried thermal paste was only slightly “bitten”. Let me remind you - the result on cold water from the tap.

The next test subject is a dead inkjet cartridge. It has been lying for 3 years, occasionally used as a trick printer.

The result of rinsing is still unclear - the refilled ink did not flow from the nozzles, but the napkin on which the cartridge was left to dry for a day was partially saturated with ink. Some nozzles "punched" but recovery is still far away, the cartridge is soaking. Perhaps I will try with cleansing liquids (there was water). Cartridge is long dead I don't feel sorry for him! The cleaning experiment was conducted solely for review (in terms of whether it will help or not) after watching the video

The next test is on a piece of foil. Ultrasound shakes and gnaws off small particles from the foil. At 30W it's slower and more accurate, at 50w it's faster and more noticeable. Torn off particles accumulate at the bottom of the bath. Everything is accompanied by the sound of bzzzzzzzzzzzzzzzzzzzzzzz

After 5 minutes

An excellent result is shown by a bath on jewelry. Added "Mr Muscle for glasses" to the water.

The cost of cleaning jewelry in jewelry stores is from 100 rubles. “Jewelry is best washed with special solutions in an ultrasonic cleaner. This method allows you to wash the most inaccessible places. Stones and metal after ultrasonic cleaning acquire their natural original luster.
The cost of such a procedure is low - 150-200 rubles. and takes no more than 15 minutes.

My camera does not know how to shoot video, so for example I see from a pipe.

UPD: Motorists. The bath will not be able to reanimate mechanically clogged nozzles. Spark plugs with an insulator punched into the body also do not make sense to rinse. Blocks, connectors are cleaned quite well from oxides, deeply ingrained rust requires mechanical removal.

I know about the existence of other trading platforms, everyone decides where to buy.
Thank you for your attention!
