Description

Technical Field

[0001] This invention belongs to the field of clothing cleaning technology, specifically, it relates to a gas-liquid mixed self-cleaning device and method for stains on clothing surfaces. Background Technology

[0002] In daily life and clothing care scenarios, the need to clean clothes stained with dirt is common. However, traditional cleaning methods have many limitations. Conventional household washing machines rely on water washing, which requires a lot of water and can easily cause over-washing of the entire garment when dealing with localized stains. This not only wastes resources but may also damage clothing fibers and shorten the lifespan of the garment. While hand washing can target localized stains, manual rubbing has limited effectiveness in cleaning stubborn stains (such as oil stains on collars and cuffs, juice stains, etc.) and is labor-intensive and time-consuming. Furthermore, uneven force during the cleaning process can easily cause the garment to deform.

[0003] While some small clothing cleaning tools exist on the market, they generally suffer from poor cleaning performance. For example, some simple wiping tools can only remove some dust from the surface of clothing and are often powerless against stubborn stains. Some spray cleaning products, due to their poor spray uniformity and insufficient gas-liquid mixing, cannot effectively penetrate the cleaning agent into the clothing fibers, making it difficult to achieve deep cleaning of stains. In view of this, the present invention is proposed. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a gas-liquid mixing self-cleaning device and method for clothing surface stains that can overcome or at least partially solve the above problems.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: a gas-liquid mixing self-cleaning device for clothing surface stains, including a water storage shell, a working chamber opened at the lower end of the water storage shell, and further including: an ultrasonic transducer, which is fixedly connected in a circumferentially equidistant manner within the working chamber, the input end of the ultrasonic transducer being electrically connected to the output end of an ultrasonic generator via a cable; the vibrating end of the ultrasonic transducer extending upward out of the working chamber and being fixedly connected to a vibrator; an intercepting filter plate, which is detachably connected to the water storage shell via threads and located above the vibrator; a rotating shaft, which is rotatably connected to the middle position of the intercepting filter plate; and an agitating plate, which is circumferentially equidistantly mounted on the rotating shaft; a drain valve pipe is connected to the lower end of one side of the water storage shell.

[0006] To facilitate the provision of sufficient cavitation nuclei for the cavitation process, a water supply channel is further provided inside the rotating shaft. Multiple jet pipes are fixedly connected in a circular pattern between the vibrator and the intercepting filter plate on the rotating shaft. An air pump is fixedly installed on one side of the working chamber. The air supply end of the air pump is rotatably connected to the water supply channel of the rotating shaft through a rotary joint.

[0007] To facilitate the rotation of the rotating shaft using gas, the jet pipe is further made of rigid material, with the jet nozzle facing downwards and inclined.

[0008] To facilitate quick disassembly and replacement of the agitator plate, a threaded post is threadedly connected to one end of the rotating axis that passes through the intercepting filter plate, and the agitator plate is fixedly connected to the threaded post.

[0009] To further improve the cleaning effect on impurities in sewage, multiple connecting rods are fixedly connected in a circular pattern at equal intervals on the rotating shaft. The connecting rods are located above the jet pipe, and an inclined scraper is fixedly connected to the end of the connecting rod away from the rotating shaft. The inclined scraper slides against the bottom of the water storage shell to push the impurities generated from cleaning clothes toward one side of the drain valve pipe.

[0010] To facilitate heat dissipation of the ultrasonic transducer, multiple rows of breathable filter holes are equidistantly provided on the side of the working chamber away from the air pump.

[0011] To further improve the heat dissipation effect of the ultrasonic transducer, multiple rows of insertion ports are equidistantly opened between the inside of the water storage shell and the working chamber. A heat exchange copper column is fixedly connected to each insertion port. The lower end of the heat exchange copper column extends into the working chamber and is located on the side close to the vent filter hole. The upper end of the heat exchange copper column is flush with the bottom of the water storage shell.

[0012] To facilitate folding and reduce space occupation when not in use, the water storage shell further includes a rigid bottom shell, a flexible ring, and a rigid top ring. The working chamber is opened inside the rigid bottom shell, the intercepting filter plate is threadedly connected to the rigid bottom shell, the flexible ring is fixedly connected to the upper end of the rigid bottom shell, and the rigid top ring is fixedly connected to the upper end of the flexible ring. The rigid bottom shell, the flexible ring, and the rigid top ring are integrally formed.

[0013] To further reduce the overall weight of the device and make it easier to carry, the rigid bottom shell, flexible ring, and rigid top ring are all made of plastic ring plates.

[0014] A method for using a gas-liquid mixing self-cleaning device for clothing surface stains mainly includes the following steps: S1: Check the device, add appropriate cleaning solution, and place the clothes in the cleaning solution; S2: Connect the power supply, turn on the ultrasonic transducer to make the vibrator vibrate at high frequency, control the rotating shaft to drive the stirring plate to rotate, and set the cleaning time of 3-12 minutes according to the stubbornness of the stains. S3: Observe the stains during the cleaning process, and pause to adjust the concentration of the cleaning solution or the cleaning time if necessary; S4: After cleaning, turn off the power, open the drain valve to drain the waste liquid, and take out the clothes to rinse and dry.

[0015] After adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art: In terms of the usage process, the device is first checked and the cleaning medium is added. After gently placing the clothes to be cleaned, the device is started. The ultrasonic transducer and vibrator generate high-frequency vibration to form a cavitation effect. With the help of the rotating shaft driving the stirring plate to push the cleaning liquid to circulate and agitate, gas-liquid mixing is achieved. The cleaning time is set according to the degree of stain to complete the cleaning. Finally, the device is turned off, drained, and the items are removed. Its effect is significant. The high-frequency vibration and liquid circulation work together to efficiently break and peel off stains such as oil stains and sweat stains with the help of the cavitation effect. It has good cleaning power for stubborn stains on collars and cuffs, as well as juice and coffee stains. The flexible liquid agitation replaces strong rubbing. With the help of the intercepting filter plate, it reduces the pulling of clothing fibers and the scratching of hardware, reduces the amount of detergent used, protects the clothing material, and extends the service life. Moreover, it is simple to operate and has a compact structure, which is suitable for home and portable scenarios. It can also be extended to the cleaning of small fabric items such as scarves, providing a high-quality solution for clothing care.

[0016] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0020] Example 1: Reference Figures 1-6 A gas-liquid mixing self-cleaning device for clothing surface stains includes a water storage shell 1, with a working chamber 104 at the lower end of the water storage shell 1. It also includes: an ultrasonic transducer 3, circumferentially and equidistantly fixedly connected within the working chamber 104; the input end of the ultrasonic transducer 3 is electrically connected to the output end of an ultrasonic generator via a cable; the vibrating end of the ultrasonic transducer 3 extends upward out of the working chamber 104 and is fixedly connected to a vibrator 301; an intercepting filter plate 2, detachably connected to the water storage shell 1 via threads and located above the vibrator 301; a rotating shaft 4, rotatably connected to the middle position of the intercepting filter plate 2; and an agitating plate 402, circumferentially and equidistantly mounted on the rotating shaft 4; a drain valve pipe is connected to the lower end of one side of the water storage shell 1.

[0021] When cleaning one or a few stained garments, first place the device in the designated location. Then, ensure that the water tank 1 is undamaged, the drain valve is closed, the filter plate 2 is securely installed, the rotating shaft 4 and the stirring plate 402 rotate freely, and the ultrasonic transducer 3 and the vibrator 301 are not loose. After the preliminary work is completed, inject an appropriate amount of cleaning liquid (such as water, special detergent, etc., depending on the type of stain) into the water tank 1. Depending on the amount of clothing, inject an appropriate amount of water into the water tank 1 and add an appropriate amount of detergent. Then, place the stained clothing in the cleaning liquid, and then turn on the power. The ultrasonic generator will work, driving the ultrasonic transducer 3 and the vibrator 301 to generate high-frequency vibration through the cable, so that the cleaning liquid forms a high-frequency oscillation field. At the same time, control the rotating shaft 4 to drive the stirring plate 402 to rotate, pushing the cleaning liquid to circulate and agitate in the water tank 1, realizing gas-liquid mixing (during the vibration process, the liquid comes into contact with the air to form tiny bubbles, which, together with the agitation, enhance the mixing effect).

[0022] Depending on the stubbornness of the stains, the cleaning time can be set (generally 3-5 minutes for light stains and 8-12 minutes for heavy stains). During the cleaning process, the high-frequency vibrating cleaning liquid penetrates the clothing fibers, breaking and peeling off the stains. The stirring plate 402 drives the liquid flow, allowing different parts of the clothing to continuously contact the micro-bubbles for cavitation reaction, ensuring uniform cleaning.

[0023] After cleaning, turn off the ultrasonic generator and the rotation power source of the rotating shaft 4, and disconnect the power. Then open the drain valve to drain the used cleaning solution from the water tank 1. After the liquid is drained, take out the clothes and rinse and dry them as needed. When there are many impurities attached to the bottom of the water tank 1, or when it is necessary to clean the surface of the vibrator 301, the intercepting filter plate 2 can be taken out, and then the user can perform the corresponding cleaning operation.

[0024] The high-frequency vibration generated by the ultrasonic transducer 3 and the vibrator 301 can cause the cleaning liquid to form a cavitation effect - the tiny bubbles in the liquid collapse due to vibration, generating instantaneous high pressure to impact the clothing fibers, effectively breaking the adhesive structure of stains such as oil stains, sweat stains, and dust. The stirring plate 402 enhances the liquid circulation, allowing the cleaning liquid and bubbles to fully cover the clothing, avoiding dead corners in local cleaning. The cleaning effect is particularly significant for stubborn stains on easily soiled areas such as collars and cuffs.

[0025] Compared to traditional strong rubbing and cleaning, this device removes stains through high-frequency vibration and flexible liquid agitation, reducing the direct force pulling on clothing fibers and lowering the risk of clothing deformation and pilling. The intercepting filter plate 2 prevents clothing from directly contacting the ultrasonic transducer 3 and rotating parts, preventing hardware scratches and damage to the clothing fabric.

[0026] Because of its high cleaning efficiency, it can reduce the amount of detergent used (or clean light stains with only water), reduce the corrosive effect of chemical residues on clothing materials (such as sensitive fabrics like wool and silk), and extend the service life of clothing.

[0027] This device has a simple operation process, requiring no complicated manual rubbing. It can automatically complete the cleaning operation with just one button. In addition to regular clothing cleaning, due to the flexible characteristics of the gas-liquid mixed cleaning mode, it can also be used to treat stains on small fabric items such as scarves and fabric ornaments, thus broadening its application range.

[0028] In summary, this gas-liquid hybrid self-cleaning device for clothing surfaces achieves efficient and gentle stain removal through the synergistic effect of ultrasonic vibration and liquid agitation, balancing cleaning power with clothing protection. It is easy to operate and adaptable to various scenarios requiring localized or small-scale cleaning of clothing, providing a superior solution for daily clothing care.

[0029] Example 2: Reference Figures 1-6A gas-liquid mixing self-cleaning device for clothing surface stains is basically the same as in Example 1, but with a further improvement. A water supply channel is opened inside the rotating shaft 4. Multiple jet pipes 404 are fixedly connected in a circumferentially equidistant manner on the rotating shaft 4 between the vibrator 301 and the intercepting filter plate 2. An air pump 403 is fixedly installed on one side of the working chamber 104. The air supply end of the air pump 403 is rotatably connected to the water supply channel of the rotating shaft 4 through a rotary joint 407. The air pump 403 delivers gas to the water supply channel of the rotating shaft 4 through the rotary joint 407, and then sprays it into the cleaning liquid area near the vibrator 301 through the jet pipes 404. This provides a sufficient source of cavitation nuclei for the cavitation process, significantly increases the number of nuclei in the liquid that can form cavitation bubbles, greatly enhances the cavitation effect, and generates and collapses a large number of cavitation bubbles, releasing a powerful impact force. This can more efficiently break the stain structure between clothing fibers, separating stubborn stains such as oil stains and sweat stains from the clothing, effectively improving cleaning efficiency and cleanliness.

[0030] The jet pipe 404 is a rigid pipe with its nozzle facing downwards and angled. The rigid pipe structure ensures the stability and strength of the gas jet. The downward-facing and angled nozzle creates a circumferential component of the reaction force generated during gas jetting. This component acts directly on the rotating shaft 4, causing it to rotate continuously. This, in turn, drives the agitator plate 402 to circulate and agitate the cleaning liquid. No additional drive motor is required, simplifying the device structure and reducing energy consumption. At the same time, the angled jetting airflow enhances liquid flow, further strengthening gas-liquid mixing and cavitation effects, thus improving the cleaning efficiency of clothing stains.

[0031] Example 3: Reference Figures 1-6 A gas-liquid mixing self-cleaning device for clothing surface stains is basically the same as in Embodiment 2, but with a further improvement. The rotating shaft 4 extends upward through one end of the intercepting filter plate 2 and is connected to a threaded post 401 by a thread. The agitator 402 is fixedly connected to the threaded post 401. The rotating shaft 4 is connected to the threaded post 401 by a thread, thus fixing the agitator 402 to the threaded post 401. Taking advantage of the convenient disassembly and assembly characteristics of the threaded connection, when the agitator 402 is worn or aged, or when it needs to be replaced with a different shape or size agitator 402 for cleaning needs, it is only necessary to simply twist the threaded post 401 to quickly complete the disassembly and replacement. No complicated tools or professional operation are required, reducing the difficulty of maintenance. At the same time, it is also convenient for users to flexibly adapt different agitators 402 according to the clothing material and stain type to optimize the cleaning effect. Multiple connecting rods 405 are fixedly connected in a circular pattern at equal intervals on the rotating shaft 4. The connecting rods 405 are located above the air jet pipe 404. An inclined scraper 406 is fixedly connected to the end of the connecting rod 405 away from the rotating shaft 4. The inclined scraper 406 slides against the bottom of the water storage shell 1 and is used to push the impurities generated during cleaning of clothes toward one side of the drain valve pipe. The inclined scraper 406 is fixed to the connecting rods 405 on the rotating shaft 4. During drainage, the rotating shaft 4 drives the inclined scraper 406 to rotate through the connecting rods 405. The inclined scraper 406 slides against the bottom of the water storage shell 1. Utilizing its own tilt angle and rotational power, it can efficiently gather the stains, lint and other impurities that fall off the clothes during the cleaning process and push them toward one side of the drain valve pipe, avoiding the residue of impurities or their attachment to the clothes and causing secondary pollution. At the same time, this structure works in conjunction with the stirring plate 402 and the air jet pipe 404 to form an integrated cleaning-stirring-discharge process, which significantly improves cleaning efficiency and overall machine operation stability.

[0032] Example 4: Reference Figures 1-6 A gas-liquid mixing self-cleaning device for clothing surface stains is basically the same as in Example 3, but further, multiple rows of breathable filter holes 105 are equidistantly provided on the side of the working chamber 104 away from the air pump 403. The multiple rows of breathable filter holes 105 on the side of the working chamber 104 away from the air pump 403 form a gas convection channel with the air pump 403. When the air pump 403 is working, outside air is drawn into the working chamber 104 through the breathable filter holes 105. During the air flow in the chamber, it can carry away the heat generated by the high-frequency vibration of the ultrasonic transducer 3 in time, effectively reducing the working temperature of the transducer, avoiding performance degradation or component damage due to overheating, and ensuring the continuous and stable operation of the ultrasonic cleaning function. At the same time, the filter hole structure can prevent impurities from entering the working chamber 104, ensuring the cleanliness of the device and the safety of operation.

[0033] Multiple rows of insertion ports are equidistantly arranged between the interior of the water storage shell 1 and the working chamber 104. Heat exchange copper pillars 106 are fixedly connected to these insertion ports. The lower ends of the heat exchange copper pillars 106 extend into the working chamber 104 and are located near the vent filter holes 105. The upper ends of the heat exchange copper pillars 106 are flush with the bottom of the water storage shell 1. The heat exchange copper pillars 106 installed inside the water storage shell 1 penetrate the working chamber 104 through the insertion ports. Utilizing the excellent thermal conductivity of copper, the heat generated by the ultrasonic transducer 3 within the working chamber 104 is rapidly conducted away. At the bottom of the water storage tank 1, the lower end of the heat exchange copper column 106 is close to the vent filter hole 105. With the airflow driven by the air pump 403, the heat dissipation is further accelerated, forming a dual heat dissipation mechanism of conduction and convection. This effectively reduces the operating temperature of the transducer and avoids performance degradation and component damage caused by overheating. In addition, the design of the copper column being flush with the bottom of the water storage tank 1 does not occupy extra space, ensuring a compact device structure. It can also use the contact between the cleaning liquid and the bottom of the water storage tank 1 to assist in heat dissipation, improving heat dissipation efficiency and device operation stability.

[0034] Example 5: Reference Figures 1-6 A gas-liquid mixing self-cleaning device for clothing surface stains is basically the same as in Example 4, but with a further improvement: the water storage shell 1 includes a rigid bottom shell 101, a flexible ring 102, and a rigid top ring 103. The working chamber 104 is opened inside the rigid bottom shell 101. The intercepting filter plate 2 is threadedly connected to the rigid bottom shell 101. The flexible ring 102 is fixedly connected to the upper end of the rigid bottom shell 101, and the rigid top ring 103 is fixedly connected to the upper end of the flexible ring 102. The rigid bottom shell 101, the flexible ring 102, and the rigid top ring 103 are integrally formed. The water storage shell 1 is constructed using a rigid bottom shell 101, a flexible ring 102, and a rigid top ring 103. The composite structure design of the soft ring 102 and the hard top ring 103 utilizes the elastic deformation characteristics of the soft ring 102 to allow the hard top ring 103 to be folded towards the hard bottom shell 101 during storage, significantly reducing the overall height of the device and minimizing space occupation. The one-piece molding process ensures structural sealing and stability, and the folding process does not affect the liquid storage function or the connection of internal components. The hard bottom shell 101 protects the precision components inside the working chamber 104, and the hard top ring 103 maintains the open shape for easy operation. It balances portability and storage with reliable use, making it especially suitable for flexible carrying and storage in scenarios such as travel and business trips.

[0035] The rigid bottom shell 101, flexible ring 102, and rigid top ring 103 are all made of plastic sheets. Plastic sheets have low density and are lightweight, which significantly reduces the overall weight of the device and makes it easy to carry. They are also highly malleable, which is conducive to the realization of complex structural designs through one-piece molding processes, ensuring the folding function and sealing of the water storage shell 1. At the same time, plastic sheets have good chemical stability, are resistant to corrosion by cleaning liquids, and extend the service life of the device. In addition, plastic sheets have low cost, which can effectively control production costs, and the processing technology is mature, which is conducive to large-scale production and market promotion.

[0036] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention.
