Description

Technical Field

[0001] This invention relates to the field of food cleaning technology, and in particular to a food cleaning tank and cleaning device. Background Technology

[0002] With increasing public awareness of food safety, efficient purification technologies for fruits, vegetables, and meats are receiving growing attention. Currently, intelligent cleaning devices integrating sterilization and pesticide residue degradation are widely available on the market. Their core components typically include a purification module, effectively removing microorganisms and chemical residues from the surface of food. To prevent food debris, sand, and fine fibers from entering the purification module and causing blockages or damage, most devices are equipped with draining components (such as drain baskets or filter racks) within their cleaning chambers to initially intercept large particles of impurities.

[0003] However, existing drainage structures can only effectively block larger particles such as leaves and fruit peels, lacking the ability to effectively intercept smaller particles. This allows some impurities to seep into the purification module, accumulating over time and reducing purification efficiency, thus affecting the purification effect and even causing equipment malfunction. To maintain equipment performance and hygiene standards, users have to frequently disassemble the purification module for manual cleaning, which is not only cumbersome and costly but also poses a risk of secondary contamination, severely diminishing the ease of use and user experience. Summary of the Invention

[0004] This invention addresses the technical problems existing in the prior art by providing a food washing tank and washing device. Through structural optimization, it achieves a self-cleaning function, reduces the frequency of manual cleaning by users, and improves the convenience and reliability of the equipment while ensuring purification efficiency.

[0005] The technical solution adopted by the present invention to solve its technical problem is as follows: a food washing tank, including a washing body, a draining component, and a purification module. The washing body is provided with a washing chamber, and the bottom of the washing chamber is provided with an openable and closable drain outlet. The bottom of the washing body is provided with an airflow channel. The purification module is disposed on the bottom wall of the washing chamber and located on one side of the drain outlet. The draining component is disposed in the washing chamber, and its draining area is located above the purification module. A first self-cleaning channel is formed between the draining component and the purification module, and the first self-cleaning channel is connected to the drain outlet. The bottom of the washing body is provided with an airflow channel, and the bottom surface of the washing chamber is provided with an air outlet at least in the area corresponding to the purification module. When airflow enters the airflow channel, the airflow is output through the air outlet, which can cause the first impurities falling into the first self-cleaning channel and / or the purification module to migrate along the first self-cleaning channel towards the drain outlet.

[0006] In a preferred embodiment, a second self-cleaning channel is formed between the purification module and the bottom wall of the cleaning chamber, and the second self-cleaning channel is connected to the drain outlet; when the air outlet is in the air-outlet state and / or the drain outlet is in the open state, the second impurity falling into the second self-cleaning channel migrates along the second self-cleaning channel toward the drain outlet.

[0007] In a preferred embodiment, the bottom surface of the second self-cleaning channel has a sloping structure, gradually decreasing in the direction from the end away from the drain outlet toward the drain outlet.

[0008] In a preferred embodiment, the purification module is an electrolysis generator, including an electrolysis support and multiple electrolysis plates. The multiple electrolysis plates are arranged side by side on the electrolysis support, and an elongated first grid extending along the drain outlet direction is formed between adjacent electrolysis plates. The air outlet of the bottom surface of the cleaning chamber, corresponding to the area of ​​the purification module, is located below the electrolysis plates or the first grid.

[0009] In a preferred embodiment, the draining area of ​​the draining member forms a plurality of elongated second grids, the extension direction of the second grids being non-parallel to the extension direction of the first grids.

[0010] In a preferred embodiment, the bottom surface of the cleaning chamber is provided with an installation groove, one end of the installation groove is connected to the drain outlet, and the bottom surface of the installation groove is provided with the water hole; the purification module is detachably embedded in the installation groove.

[0011] In a preferred embodiment, the draining component is a decorative cover, which is detachably embedded in the mounting groove, and the top surface of the decorative cover is higher than the upper edge of the mounting groove; the top surface of the decorative cover is an upwardly convex arc-shaped curved surface.

[0012] In a preferred embodiment, the system further includes a photo-sterilization module, which is embedded in the bottom surface of the cleaning chamber and located below the purification module.

[0013] In a preferred embodiment, the bottom of the cleaning body is provided with a valve chamber communicating with the air outlet, and the bottom of the valve chamber is provided with an air inlet communicating with the airflow channel; a one-way valve is provided in the valve chamber, and the one-way valve automatically closes when there is no airflow input to the airflow channel; when gas is introduced into the airflow channel, the airflow pushes the one-way valve to open; the air outlet is a grid structure, or includes multiple air outlet holes spaced apart.

[0014] The present invention also provides a cleaning device, including a water tank and an air supply system, and further including a food cleaning tank as described above; the food cleaning tank is movably disposed inside the water tank; the air supply system is disposed outside the water tank, the air supply system is provided with an air outlet, and the water tank is provided with a clearance through hole corresponding to the air outlet; the air inlet end of the airflow channel is detachably connected to the air outlet.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this invention, a first self-cleaning channel is formed between the draining component and the purification module, connecting to the drain outlet. The bottom of the cleaning body is provided with an airflow channel, and the bottom surface of the cleaning chamber has an air outlet in at least the area corresponding to the purification module. When airflow enters the airflow channel, the airflow exits through the air outlet, causing the first impurities falling into the first self-cleaning channel and / or the purification module to actively migrate along the first self-cleaning channel towards the drain outlet. This structural design enables the invention to achieve a self-cleaning function, significantly reducing the accumulation of the first impurities at the bottom of the cleaning chamber, preventing them from remaining or clogging the internal structure of the purification module. This significantly reduces the frequency of manual cleaning by the user while continuously ensuring purification efficiency, improving the stability of equipment operation and overall ease of use.

[0017] 2. In a preferred embodiment, a second self-cleaning channel communicating with the drain outlet is formed between the purification module and the bottom wall of the cleaning chamber. When the air outlet is open and / or the drain outlet is open, the second impurities falling into the second self-cleaning channel can migrate towards the drain outlet under the guidance of the airflow. This structural design significantly improves the self-cleaning efficiency of the present invention, effectively reduces the accumulation of impurities at the bottom of the cleaning chamber, reduces maintenance frequency, and extends the service life of the equipment. Furthermore, the bottom surface of the second self-cleaning channel adopts a sloping structure, which allows the second impurities near the drain outlet to be flushed away when the drain outlet is open, thereby further improving the self-cleaning effect.

[0018] 3. In the electrolysis generator, a first grid extending along the drain outlet is formed between adjacent electrolysis plates. This effectively guides stains, silt, and other contaminants to flow directionally during drainage or bubble boiling cleaning, significantly improving drainage efficiency and cleaning effect. Furthermore, the second grid formed by the draining element extends in a direction that is not parallel to the first grid, effectively preventing residues and particles from accumulating along a single path, significantly reducing the risk of clogging, and simultaneously improving cleaning efficiency and convenience.

[0019] 4. The top surface of the decorative cover is higher than the upper edge of the mounting groove and is designed as a convex arc-shaped surface, which can effectively guide the water flow to drain smoothly and significantly reduce the residue on the surface of the decorative cover, thereby reducing the risk of contamination to the purification module.

[0020] 5. The air outlet has a grid structure or includes multiple small-diameter air outlets. While ensuring efficient aeration, it effectively blocks large particles of impurities from entering, limiting and reducing the risk of clogging and improving system operational stability. In addition, the small-diameter design can effectively suppress turbulence disturbances when water flows into the valve cavity, avoiding impact on the check valve, thereby enhancing sealing reliability and extending equipment service life.

[0021] 6. The bottom of the cleaning body of this invention has a valve chamber connected to the air outlet. This valve chamber contains a one-way valve, which automatically closes in non-aeration states, blocking liquid from entering the airflow channel at the source. This significantly reduces liquid residue in the airflow channel, inhibiting bacterial growth and scale buildup, comprehensively improving cleaning efficiency and preventing airflow channel blockage. The air outlet has a grid structure or includes multiple small-diameter air holes, ensuring efficient aeration while effectively blocking large particles of impurities, significantly reducing the risk of blockage and improving system stability. Furthermore, the small-diameter design effectively suppresses turbulent disturbances when water enters the valve chamber, avoiding impact on the one-way valve, thereby enhancing sealing reliability and extending equipment lifespan.

[0022] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments; however, the food washing tank and washing device of the present invention are not limited to the embodiments. Attached Figure Description

[0039] In this invention, the terms "first," "second," and "third," etc., are used only to distinguish similar objects, not to describe a specific order or sequence, nor should they be construed as indicating or implying relative importance. The use of terms such as "upper," "lower," "inner," "outer," "top," and "bottom" to indicate orientation or positional relationships is based on the orientation or positional relationships shown in the accompanying drawings, and is only for the convenience of describing the invention, not to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation; therefore, it should not be construed as a limitation on the scope of protection of this invention. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0040] Furthermore, in the description of this invention, unless otherwise stated, "multiple" refers to two or more; "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0041] Please see Figures 1-7 As shown, a food washing tank of the present invention includes a washing body 1, a draining component, and a purification module. The washing body 1 has a washing chamber 11, and the bottom of the washing chamber 11 has an openable and closable drain outlet 112. An airflow channel is provided at the bottom of the washing body 1. The purification module is disposed on the bottom wall of the washing chamber 11 and located on one side of the drain outlet 112. The draining component is disposed inside the washing chamber 11, and its draining area is located above the purification module. A first self-cleaning channel 23 is formed between the draining component and the purification module (e.g., ...). Figure 4 As shown), the first self-cleaning channel 23 is connected to the drain outlet 112; the bottom of the cleaning body 1 is provided with an airflow channel, and the bottom surface of the cleaning chamber 11 is provided with an air outlet at least in the area corresponding to the purification module. When airflow enters the airflow channel, the airflow is output through the air outlet to aerate the liquid in the cleaning chamber 11 and cause the first impurities that fall into the first self-cleaning channel 23 and / or the purification module to migrate along the first self-cleaning channel 23 toward the drain outlet 112.

[0042] In this embodiment, in addition to the air outlet in the area corresponding to the purification module, the bottom surface of the cleaning chamber 11 also has air outlets evenly distributed in areas outside the purification module to fully realize the aeration function, thereby achieving efficient aeration and oxygenation of the cleaning liquid and significantly improving the removal of dirt from the surface of fruits and vegetables and the overall cleaning effect. No air outlet is provided on the bottom surface of the cleaning chamber 11 in the area where the drain outlet 112 is located, so that impurities can be deposited near the drain outlet 112.

[0043] In this embodiment, the purification module is an electrolysis generator 2, which includes an electrolysis support 21 and multiple electrolysis plates 22. The multiple electrolysis plates 22 are arranged side by side on the electrolysis support 21, and an elongated first grid 221 extending along the drain outlet 112 is formed between adjacent electrolysis plates 22. Figure 2 As shown. The air outlet on the bottom surface of the cleaning chamber 11, corresponding to the area of ​​the purification module, is located below the electrolytic plate 22 or the first grid 221. This design effectively guides the directional flow of stains, silt, etc., during drainage or bubble boiling cleaning, significantly improving drainage efficiency and cleaning effect. The draining component is preferably a decorative cover 4, whose draining area forms multiple elongated second grids 41. The extension direction of the second grids 41 is not parallel to the extension direction of the first grid 221; preferably, they are perpendicular to each other. Through the intersecting configuration of the first grid 221 and the second grids 41, the path of continuous accumulation of residue or particles in a single direction can be effectively blocked, thereby significantly reducing the risk of blockage of the electrolytic generator 2 due to particle accumulation. In other embodiments, the purification module includes at least one of an ultrasonic generator, an ozone generator, etc. In other embodiments, the draining component is a drain basket.

[0044] In this embodiment, the bottom surface of the cleaning chamber 11 is provided with an installation groove 113, one end of the installation groove 113 is connected to the drain outlet 112, and the bottom surface of the installation groove 113 is provided with an air outlet; the purification module (i.e., the electrolysis generator 2) is detachably embedded in the installation groove 113. Specifically, the mounting groove 113 has L-shaped slots 115 on both inner walls in its width direction, and the electrolysis bracket 21 of the electrolysis generator 2 has a matching locking block 211 on the corresponding side. During installation, the locking block 211 slides into the vertical section of the L-shaped slot. As the electrolysis generator 2 moves along the direction of the drain outlet 112, the locking block 211 finally locks into the horizontal section of the L-shaped slot 115, achieving locking and structural fixation. During disassembly, force is applied along the drain outlet 112 to push the electrolysis generator 2, causing the locking block 211 to slide along the horizontal end of the L-shaped slot 115 and return to the vertical section, releasing the locking limit. Then, the electrolysis generator 2 can be easily removed upwards. Furthermore, a handle groove 212 is provided at the end of the electrolysis generator 2 near the drain outlet 112 to facilitate the user's application of force during disassembly, improving operational convenience.

[0045] The top surface of the decorative cover 4 is higher than the upper edge of the mounting groove 113 and is designed as a convex arc-shaped curved surface. Specifically, the perimeter of the decorative cover 4 is rectangular, extending along the drain outlet 112, and its top surface has a vertical cross-section in the width direction that is an arc shape with lower sides and a higher middle. Figure 5 As shown. This design effectively guides the water flow to drain smoothly, significantly reducing the residue residue on the surface of the decorative cover 4, thereby reducing the risk of contamination to the purification module (i.e., the electrolysis generator 2).

[0046] In a preferred embodiment, a second self-cleaning channel 24 is formed between the purification module (i.e., the electrolysis generator 2) and the bottom wall of the cleaning chamber 11 (specifically, the bottom surface of the mounting groove 113). This second self-cleaning channel 24 is connected to the drain outlet 112. When the air outlet is in the air-outlet state and / or the drain outlet 112 is open, the second impurities falling into the second self-cleaning channel 24 migrate along the second self-cleaning channel 24 towards the drain outlet 112. The first impurities include impurities that can pass through the drain piece (i.e., the decorative cover 4) but cannot enter the purification module (i.e., the electrolysis generator 2), with a particle size of about 2-4 mm, such as small pieces of broken leaves, large stems, etc. In addition, the first impurities may also include impurities that can enter the purification module and can be pushed upward into the first self-cleaning channel 23 by the airflow. The second impurities include impurities that can pass through the drain piece and the purification module and enter the second self-cleaning channel 24, such as mud, gravel, or small stems, etc. The second grid 41 on the decorative cover 4 can intercept and block large particles such as broken leaves and branches from passing through, effectively preventing such impurities from entering the first self-cleaning channel 23, thereby reducing the risk of blockage.

[0047] Furthermore, the bottom surface of the second self-cleaning channel 24 has a sloping structure, gradually decreasing from the end away from the drain outlet 112 towards the drain outlet 112. This allows the second impurities near the drain outlet 112 to be flushed away when the drain outlet 112 is opened, thereby improving the self-cleaning effect.

[0048] The present invention also includes a photo-sterilization module 3, which is embedded in the bottom surface of the cleaning chamber 11 and located below the purification treatment module (i.e., the electrolysis generator 2). It can perform cleaning and sterilization of the cleaning chamber 11, as well as self-cleaning and sterilization, and also function as a breathing ambient light. Specifically, the photo-sterilization module 3 includes a UV blue light panel 31 and a transparent or semi-transparent lampshade 32. The panel 31 is fixed to the lampshade 32 with fasteners. The photo-sterilization module 3 is specifically embedded in a receiving groove 114 opened in the central area of ​​the mounting groove 113. The lampshade 32 is sealed with the inner walls of the receiving groove 114 by a sealing ring 33 to ensure waterproof performance.

[0049] like Figure 6 As shown, the bottom of the cleaning body 1 has a valve chamber 162 connected to the air outlet below it. The bottom of the valve chamber 162 has an air inlet 161 connected to the airflow channel. The air inlet 161, valve chamber 162, and air outlet together can be referred to as the aeration section 16. A one-way valve is installed inside the valve chamber 162. When there is no airflow into the airflow channel, the one-way valve automatically closes; when gas is introduced into the airflow channel, the airflow pushes the one-way valve open. Therefore, this invention can block liquid from entering the airflow channel at the source, significantly reducing liquid residue in the airflow channel, thereby inhibiting bacterial growth and scale deposition, comprehensively improving cleaning efficiency, and preventing blockage of the airflow channel.

[0050] As a preferred embodiment, the one-way valve includes a valve core 17 that relies on self-realignment, requiring no external drive or spring mechanism. It has a simple structure, high reliability, and is not easily affected by mud, sand, or dirt. During routine maintenance, even if a small amount of impurities enter the valve cavity 162, the deposits can be easily removed by simply shaking the valve core 17 or by using low-pressure flushing, ensuring that the valve core 17 maintains high sealing performance for a long time.

[0051] The valve core 17 is preferably a spherical structure, which, thanks to its excellent rolling characteristics, enables automatic reset in multiple directions within three-dimensional space. To improve the reset accuracy and response speed of the valve core 17, the bottom surface of the valve cavity 162 is provided with a first guide slope 1621 surrounding the air inlet 161. This first guide slope 1621 has a ring-shaped structure that is wider at the top and narrower at the bottom, which can accurately guide the valve core 17 back to the center position, ensuring a stable, rapid, and reliable reset process. In this embodiment, the valve core 17 is a solid plastic sphere. Specifically, the valve core 17 can be made of engineering plastics with a density slightly greater than that of water, such as POM (polyoxymethylene) or PET (polyethylene terephthalate), whose density is about 0.4 g / cm³ higher than that of water. This allows the valve core 17 to be stably sealed to the air inlet 161 by its own weight when there is no air pressure, and to be opened under very small positive air pressure, achieving efficient opening and closing, thereby significantly reducing air source energy consumption and improving system energy efficiency.

[0052] In this embodiment, the air outlet includes multiple small-diameter air holes 163, which effectively block large particles of impurities from entering while ensuring efficient aeration, significantly reducing the risk of clogging and improving the stability of system operation. Furthermore, the small-diameter design effectively suppresses turbulent disturbances when water flows into the valve cavity 162, avoiding impact on the valve core 17 and thus enhancing sealing reliability. The multiple air holes 163 are arranged radially from the center, with at least one air hole 163 located at the center and the remaining air holes 163 evenly arranged around it circumferentially; of course, the layout of the multiple air holes 163 is not limited to a radial arrangement, and other reasonable layouts such as a rectangular array can also be used. In other embodiments, the air outlet has a grid structure composed of intersecting ribs, which also effectively blocks large particles of impurities from entering and effectively suppresses turbulent disturbances when water flows into the valve cavity 162, thereby reducing the impact on the valve core 17. The bottom of each air outlet 163 is designed with beveled or rounded corners, which not only helps the airflow to be discharged smoothly, but also provides a guiding effect when mud or dirt enters the valve chamber 162. With the help of airflow, the mud and dirt are smoothly carried out along the bevel, effectively preventing blockage and improving the reliability of exhaust and self-cleaning ability.

[0053] like Figure 6 , Figure 7As shown, a second guide slope 1611 is provided at the bottom periphery of the air inlet 161. The second guide slope 1611 has a ring-shaped structure that is narrow at the top and wide at the bottom, which can effectively guide the airflow to smoothly enter the air inlet 161.

[0054] like Figure 1 , Figures 5-7 As shown, the airflow channel includes an inlet section 14 and an outlet section 15 connected sequentially along the airflow direction. The bottom wall of the inlet section 14 slopes upward from the inlet end 143 of the airflow channel along the airflow direction. The outlet section 15 extends upward from the top of the inlet section 14 and communicates with the air inlet 161 of each aeration section 16. In this embodiment, the outlet section 15 is a columnar channel extending vertically upward, but it is not limited to this.

[0055] Preferably, such as Figure 1 As shown, the air intake section 14 includes an air intake main section 141 and multiple air intake sub-sections 142 connected to the air intake main section 141. One end of the air intake main section 141 forms an air intake end 143 of the airflow channel, and its bottom wall slopes upward from the air intake end 143 to the other end. The multiple air intake sub-sections 142 are distributed on both sides of the extension direction of the air intake main section 141, and the bottom wall of each air intake sub-section 142 slopes upward from the end connected to the air intake main section 141 to the end away from the air intake main section 141. Multiple air outlet sections 15 and aeration sections 16 are provided, and each air outlet section 15 and aeration section 16 are connected in a one-to-one correspondence. The air intake main section 141 and each air intake sub-section 142 correspond to at least one air outlet section 15. This layout of the air intake section 14, combined with the multiple air outlet sections 15, enables multi-point air outlet, providing a structural basis for the flexible layout of multiple aeration sections 16.

[0056] To effectively compensate for pressure loss along the airflow during long-distance transport, alleviate pressure attenuation at the far end, and achieve stable and uniform airflow transport, the cross-sectional area of ​​the intake section 141 is gradually reduced along the airflow direction (i.e., from one end of the intake section 141 to the other). Specifically, the intake section 141 is composed of multiple unit segments arranged sequentially along the airflow direction, with the cross-sectional area of ​​each unit segment decreasing progressively, meaning the cross-sectional area of ​​the preceding unit segment is larger than that of the following unit segment. Each unit segment is connected to an intake sub-section 142 at least on one side of the airflow direction. Through the graded, gradually reducing structure and the synergistic effect of multi-point air intake, the uniformity of airflow distribution is further optimized, and the overall air transport efficiency of the system is improved.

[0057] like Figure 1As shown, the cleaning body 1 includes a tank 11, a bottom cover 12, and an air duct cover 13. The tank 11 has a cleaning chamber 111. The bottom cover 12 is connected to the bottom end of the tank 11. The air duct cover 13 is located between the bottom cover 12 and the tank 11, and the air duct cover 13 and the bottom cover 12 enclose an airflow channel. An aeration section 16 is formed between the air duct cover 13 and the bottom end of the tank. Specifically, the air inlet section 14 of the airflow channel is formed by sealing the air duct cover 13 and the bottom cover 12 through processes such as ultrasonic welding. Each air outlet section 15 of the airflow channel is formed on the air duct cover 13. The air outlet 161 of the aeration section 16 is located on the air duct cover 13 and corresponds to the upper end of the air outlet section 15. The valve chamber 162 is formed by the air duct cover 13 and the bottom end of the tank 11. Each air outlet 163 is located on the bottom wall of the tank 11.

[0058] In this embodiment, the drain outlet 112 is located at one end of the length direction of the bottom of the tank 11, and the drain outlet 112 is opened and closed by a plug assembly 5 through insertion and removal.

[0059] Please see Figures 1-15 As shown, a cleaning device of the present invention includes a water tank 6, an air supply system, and a food cleaning tank (hereinafter referred to as cleaning tank 8) as described in the above embodiment; the cleaning tank 8 is movably disposed inside the water tank 6; the air supply system is disposed outside the water tank 6, and the air supply system is provided with an air outlet 711, and the water tank 6 is provided with a clearance through hole 61 corresponding to the air outlet 711 (e.g., Figure 11 (As shown); the air inlet 143 of the airflow channel is detachably connected to the air outlet 711.

[0060] As a preferred embodiment, the air supply system is located outside the water tank 6, with the air inlet 143 protruding outside the cleaning tank. The air inlet 143 and the air outlet 711 are pluggable and detachable, which facilitates quick installation and disassembly by the user and improves the ease of operation and maintenance efficiency.

[0061] Furthermore, such as Figure 11 , Figure 12 As shown, the two inner sides of the water tank 6 are respectively provided with horizontally extending support rails 63 to support and guide the movement of the cleaning tank 8. The extension direction of the support rails 63 is perpendicular to the insertion and removal direction of the air inlet 143. When the cleaning tank 8 slides along the support rails 63 to the end close to the air supply system, the air inlet 143 can pass through the clearance hole 61 and be inserted into the air outlet 711 of the air supply system. This structural design enables the air inlet 143 and the air outlet 711 to be quickly and accurately aligned, significantly improving the convenience of use for users.

[0062] In this embodiment, the air supply system includes a fan 73, an air supply duct 72, and a housing 71. The fan 73 and the air supply duct 72 are located inside the housing 71, and the air outlet 711 is located in the housing 71. Therefore, the air supply system of the present invention can also be referred to as a control box 7. Figure 10 As shown, the air supply duct 72 has an arc-shaped structure, with its radial direction perpendicular to the axis of the air outlet 711. Its upper end is connected to the air outlet of the fan 73, and its lower end is connected to the air outlet 711. This design can significantly extend the airflow path of the air supply duct 72 within a limited height space, thereby effectively delaying the risk of water in the cleaning tank 8 or water tank 6 flowing back into the fan 73 along the air supply duct 72.

[0063] The control box 7 also includes a power supply component located within the box body 71, such as... Figure 10 , Figure 15 As shown, the power supply assembly includes a fixed frame 75, a movable frame 76, and multiple power supply conductive elements 77. The movable frame 76 is slidably mounted on the fixed frame 75, and the multiple power supply conductive elements 77 are fixed to the movable frame 76 and arranged parallel to each other to achieve synchronous extension and retraction. In the extended state, the multiple power supply conductive elements 77 can be electrically connected one-to-one with multiple conductive elements 18 provided on the side wall of the tank 11. A first elastic element (not shown in the figure) is provided between the movable frame 76 and the box 71 to drive the movable frame 76 to automatically reset in the retraction direction after the external force is removed. A first magnet 78 is provided on the movable frame 76 to magnetically engage with a second magnet 19 provided on the side wall of the tank 11, forming a magnetic positioning structure to ensure that the movable frame 76 is stably maintained in the working position in the extended state. The control box 7 also includes a circuit board 74 disposed within the box 71, which is electrically connected to the multiple power supply conductive elements 77 and the fan 73.

[0064] In a preferred embodiment, the control box 7 is provided with a positioning structure 10 for positioning the air inlet 143 inserted into the air outlet 711, ensuring the assembly stability and airtightness of the air inlet 143 and the air supply channel 72. Figure 11 , Figure 12 As shown, the positioning structure 10 includes a positioning rod 101 and a second elastic element 102. The positioning rod 101 is slidably disposed in the housing 71 along an axial direction perpendicular to the air outlet 711, and is held in a preset position with its end extending into the air outlet channel 72 under the action of the second elastic element 102. When the air inlet 143 is inserted into the air outlet 711, its outer surface presses against the end of the positioning rod 101, overcoming the elastic force of the second elastic element 102, and pushing the positioning rod 101 to retract in the direction of exiting the air outlet 711. After the air inlet 143 is fully in place, the end of the positioning rod 101 automatically engages in the preset positioning groove 1431 on the outer wall of the air inlet 143 under the restoring force of the second elastic element 102, thereby achieving dual axial and radial limiting of the air inlet 143.

[0065] like Figure 11 , Figure 12As shown, the air outlet 711 is equipped with a sealing assembly 9, which includes a sealing plug 91 and a third elastic member 92. The sealing plug 91 is slidably disposed within the air supply channel 72 along the axial direction of the air outlet 711, and the third elastic member 92 is disposed between the sealing plug 91 and the inner wall of the air supply channel 72. When the air inlet 143 is inserted into the air outlet 711, the air inlet 143 pushes the sealing plug 91, causing the air outlet 711 to open; when the air inlet 143 is separated from the air outlet 711, the sealing plug 91 is driven back to its original position by the third elastic member 92 and closes the air outlet 711, thereby effectively preventing water mist, splashing water or moisture backflow in the cleaning environment.

[0066] like Figure 3 As shown, the side wall of the air inlet 143 is provided with an air inlet opening 1432. When the air inlet 143 is inserted into the air outlet 711, the air inlet opening 1432 connects to the air outlet channel 72. The air inlet opening 1432 is preferably a notch structure, but is not limited to this; in other embodiments, the air inlet opening 1432 can also be a through hole structure with four surrounding walls. The setting of the air inlet opening 1432 allows airflow to directly enter the airflow channel through the air inlet opening 1432 even when the air inlet 143 pushes against the sealing plug 91 and the air outlet 711 is open, without relying on the gap between the air inlet 143 and the sealing plug 91 to achieve air intake. Thus, it can effectively avoid the inability to intake air due to the lack of an intake gap between the air inlet 143 and the sealing plug 91, or the existence of an intake gap but insufficient flow area, thereby ensuring a stable air intake volume and smooth airflow in the airflow channel 1, and improving aeration efficiency.

[0067] The working principle of this invention is as follows:

[0068] When the cleaning tank 8 moves along the support slide rail 63 to the preset working position inside the water tank 6, the second magnet 19 installed on it attracts the first magnet 78 on the movable frame 76, overcoming the elastic force of the first elastic element, and driving the movable frame 76 to slide closer to the cleaning tank 8. This causes each power supply conductive element 77 to extend and pass through the telescopic clearance hole 62 provided on the side wall of the water tank 6 into the water tank 6, achieving a reliable electrical connection with the corresponding power receiving conductive element 18 on the side wall of the tank body 1 (e.g., ...). Figure 13 As shown in the diagram, a conductive path is formed, causing the circuit board 74 to trigger the purification module (i.e., the electrolysis generator 2) to operate. When the cleaning tank 8 is removed from the preset working position, the magnetic attraction between the second magnet 19 and the first magnet 78 is released, and the movable frame 76 slides in the opposite direction under the restoring force of the first elastic element, causing each power supply conductive element 77 to retract into the box 71, disconnecting the circuit connection, and the purification module stops working.

[0069] Furthermore, when the cleaning tank 8 moves to the working position, the air inlet 143 of its airflow channel can be inserted into the air outlet 711 of the housing 71. At this time, the air inlet 143 pushes the sealing plug 91 inside the air outlet 711, opening the air outlet 711; in addition, the end of the positioning rod 101 is embedded in the positioning groove 1431 provided on the outer wall of the air inlet 143, realizing mechanical positioning and centering. When the fan 73 starts, the airflow is guided downward through the air outlet 72 and enters the interior of the airflow channel through the air inlet opening 1432, forming a stable airflow; when the airflow pressure acts on the valve core 17 at the air outlet 161, the valve core 17 is lifted and opened, and the airflow then enters the valve chamber 162 (e.g., Figure 7 As shown), the cleaning solution is released into the cleaning chamber 111 through the air outlet 163 (some air outlets may be blocked after the valve core 17 is lifted), which is not blocked by the valve core 17, thereby achieving efficient aeration and oxygenation of the cleaning solution and greatly improving the removal of dirt on the surface of fruits and vegetables and the overall cleaning effect.

[0070] During the cleaning process, large particles such as broken leaves and twigs are intercepted and blocked by the second grid 41 on the decorative cover 4; small fragments, large stems, and other first impurities pass through the first self-cleaning channel 23 of the decorative cover 4 and migrate towards the drain outlet 112 under the guidance of airflow disturbance; third impurities such as mud, gravel, or small stems pass through the decorative cover 4 and the electrolysis generator 2 in sequence into the second self-cleaning channel 24 and migrate towards the drain outlet 112 under the guidance of airflow disturbance. When the drain outlet 112 is opened, various impurities accumulated near the drain outlet 112 will be discharged from the drain outlet under the influence of water flow.

[0071] When the fan 73 stops or the airflow is interrupted, the valve core 17 automatically falls back under its own gravity, resealing the air outlet 161 and effectively preventing liquid from seeping into the airflow channel. When the cleaning tank 8 leaves the working position, the air inlet 143 of the airflow channel separates from the air outlet 711, and the sealing plug 91 at the air outlet 711 automatically returns to its original position under the automatic return of the third elastic element 92, resealing the air outlet 711 and preventing liquid from flowing back into the air supply channel 72. If a small amount of liquid accidentally seeps into the airflow channel due to valve core 17 failure, delayed closing, or the flushing process, its air inlet 143 adopts an open design, which can serve as a safe discharge channel, allowing the seeped liquid and dirt to drain naturally, greatly reducing the risk of residual liquid accumulation. Furthermore, the bottom surface of the airflow channel is designed to slope upward from the air inlet 143 along the airflow direction, so that residual liquid automatically flows to the air inlet 143 and is discharged under gravity, realizing an active self-cleaning function.

[0072] This invention achieves self-cleaning functionality by designing a first self-cleaning channel 23 and a second self-cleaning channel 24, combined with an aeration function. This significantly reduces the accumulation of impurities at the bottom of the cleaning chamber 111, preventing them from stagnating or clogging the internal structure of the purification module. Thus, while maintaining continuous purification efficiency, it greatly reduces the frequency of manual cleaning by the user, improving the stability of equipment operation and overall ease of use. Furthermore, the electrolysis generator 2 is designed to be detachable, facilitating later maintenance and replacement. Especially when stains accumulate to the point where self-cleaning is no longer possible, the electrolysis generator 2 can be completely disassembled for independent flushing and cleaning.
