Description

Technical Field

[0001] This invention relates to the field of pet grooming equipment technology, and more particularly to a self-service pet grooming device. Background Technology

[0002] With the continuous rise in urban pet ownership and the accelerated pace of modern life, self-service pet grooming services are increasingly favored by pet owners due to their convenience, affordability, and flexibility. A self-service pet grooming device is typically installed in public or semi-public spaces such as communities, pet shops, or self-service grooming outlets. Its main structure includes a grooming chamber, a water supply system, a detergent supply system, a drying system, a drainage system, and a human-machine interface control panel. To ensure that wastewater meets municipal discharge standards and prevent solid debris from clogging public pipe networks, and considering that some self-service pet grooming devices use a circulating water mode to save water, filter components need to be installed in the drainage pipes to intercept and separate solids such as hair from the wastewater.

[0003] However, the filtration components in existing self-service pet grooming devices mostly use flat mesh panels or cylindrical filters, relying on gravity or natural water flow to achieve solid-liquid separation. Pet hair, due to its long, flexible, and scaly surface, easily tangles and bridges at the filter mesh. Simultaneously, dander and other tiny particles intertwine with the hair to form a highly adhesive filter cake layer, clogging some of the mesh. This rapidly reduces the effective filtration area, slows down the drainage flow, and causes contaminants in the wastewater to remain at the bottom of the tank for extended periods. This not only prolongs the single grooming cycle and negatively impacts user experience but also accelerates bacterial growth and odor generation, further shortening the equipment's maintenance cycle and lifespan. In other words, existing self-service pet grooming devices are prone to filter clogging during the wastewater filtration process. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, the purpose of this invention is to provide a self-service pet grooming device, in which the filter screen is not easily clogged during the process of filtering grooming wastewater.

[0005] The objective of this invention is achieved through the following technical solution:

[0011] A first driving component is connected to the scraper at its driving end, and the first driving component is used to drive the scraper to move.

[0012] Furthermore, the self-service pet grooming device also includes a collection box, which is detachably installed in the filter chamber and located below the edge of the filter screen; the collection box is used to collect debris scraped onto the edge of the filter screen by the scraper.

[0013] Furthermore, the collection box is slidably inserted through the side wall of the washing and care box and into the filter chamber. The collection box is slidably connected to the filter box. A handle is provided at the end of the collection box away from the filter chamber, and the handle is located outside the washing and care box.

[0014] Furthermore, the collection box is provided in at least two locations, with the at least two collection boxes respectively located on opposite sides of the filter screen in the horizontal direction.

[0015] Furthermore, the washing and care mechanism includes a spray pipe, a hot air pipe, and a second drive assembly. The spray pipe and the hot air pipe are both located inside the washing and care chamber. The drive end of the second drive assembly is connected to the spray pipe and the hot air pipe for driving the spray pipe and the hot air pipe to reciprocate along the length of the washing and care chamber.

[0016] Furthermore, the washing and care box also has an electrical installation cavity; the second drive assembly includes a motor, a first lead screw, a connecting block, and a guide rod. The guide rod is installed inside the washing and care cavity and extends along the length of the washing and care cavity; the connecting block is slidably sleeved on the outside of the guide rod, and the spray pipe and the hot air pipe are both installed on the connecting block; the first lead screw is rotatably installed in the washing and care cavity and screwed onto the connecting block so that the connecting block can slide along the axial direction of the guide rod; one end of the first lead screw is rotatably inserted through the side wall of the washing and care cavity and into the electrical installation cavity; the motor is installed in the electrical installation cavity, and the motor is driven by the first lead screw.

[0017] Furthermore, the second drive component is connected to the first drive component via a central transmission mechanism.

[0018] Further, the first drive assembly includes a slide rod and a second lead screw.

[0019] Furthermore, the central transmission mechanism also includes a transmission chain, through which the driving wheel is connected to the driven wheel.

[0020] Furthermore, the filter screen is provided with a plurality of first filter holes, and the collection box is provided with a plurality of second filter holes; the diameter of each second filter hole is less than or equal to the diameter of each first filter hole.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. The pet washing box is equipped with a washing chamber, a door, a water outlet, and a drain outlet. The washing chamber is used to hold the pet; the door is located on the side wall of the washing box and is used to open or close the opening of the washing chamber; the water outlet is located on the bottom wall of the washing chamber; the drain outlet is located on the side wall of the washing box; and the washing mechanism is installed in the washing box to wash the pet inside the washing chamber. The operator can open the door to place the pet into the washing chamber, close the door, and then start the washing mechanism to begin washing. Wastewater containing pet hair and dander generated during the washing process can be discharged from the bottom wall of the washing chamber through the water outlet under gravity, preventing wastewater from accumulating inside the washing chamber and affecting the washing effect or causing bacterial growth. This provides a wastewater source and a directional flow path for subsequent filtration treatment, allowing wastewater containing pet hair and dander to be collected and guided to the filtration stage.

[0023] 2. The filter box is installed at the bottom of the washing and care tank. The filter box is equipped with a filter screen and a filter chamber. The filter screen is housed in the filter chamber. The water outlet and the drain outlet are located on opposite sides of the filter screen. The water outlet, filter chamber and drain outlet are connected in sequence along the flow direction of the washing and care wastewater. Thus, the wastewater containing impurities discharged from the water outlet enters the filter chamber under the action of gravity and flows through the filter screen. The solid impurities in the wastewater are trapped by the filter screen on the side of the filter screen near the water outlet. The filtered clear liquid continues to flow downward through the filter screen and is discharged from the washing and care tank through the drain outlet, thus achieving the filtration of washing and care wastewater.

[0024] 3. The scraper is movably positioned within the filter chamber, near the outlet of the filter screen. The scraper is used to scrape debris from the filter screen to its edge. The drive end of the first drive assembly is connected to the scraper, and the first drive assembly drives the scraper to move. Thus, under the action of the first drive assembly, the scraper can scrape up hair and debris trapped on the filter screen surface and push them to the edge area of ​​the filter screen during its movement, keeping the mesh openings in the central area of ​​the filter screen clear. The scraper's cleaning action can be performed periodically or continuously during the filtration process, achieving automatic cleaning without disassembling the filter screen. This reduces the frequency and maintenance costs of manual filter screen cleaning and prevents the filter screen from clogging during the filtration of washing wastewater.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0033] See Figures 1-4 The present invention illustrates a preferred embodiment of a self-service pet grooming device, comprising: a grooming box 1, a grooming mechanism 2, a filter box 3, a scraper 4, and a first drive assembly 5.

[0034] The pet grooming box 1 includes a grooming chamber 11, a door 12, a water outlet 13, and a drain outlet 14. The grooming chamber 11 is used to hold the pet. The door 12 is located on the side wall of the grooming box 1 and is used to open or close the opening of the grooming chamber 11. The water outlet 13 is located on the bottom wall of the grooming chamber 11. The drain outlet 14 is located on the side wall of the grooming box 1. The grooming box 1 can be made of stainless steel or engineering plastic, and has good waterproof and corrosion resistance. The grooming chamber 11 is a hollow cavity inside the grooming box 1, and its shape can be a cuboid or a rounded cuboid. The door 12 can be hinged to the side wall of the grooming box 1. A sealing strip can be installed between the door 12 and the grooming box 1 to prevent water leakage from the door gap during pet grooming. A transparent observation window can be installed on the door 12 for easy observation of the internal grooming status. The water outlet 13 is located at the lowest point of the bottom wall of the washing chamber 11, allowing the wastewater to be completely discharged from the washing chamber 11 under gravity and flow into the filter box 3. The drain outlet 14 is located at the lower part of the side wall of the washing box 1 and is used to connect to the external drainage pipe. This structure provides pets with an independent washing space, allowing the washing process to take place within the enclosed washing chamber 11, preventing water splashing and pet escape. At the same time, the wastewater is discharged from the washing chamber 11 through the water outlet 13 and then discharged from the washing box 1 through the drain outlet 14.

[0035] The washing and grooming mechanism 2 is installed in the washing and grooming box 1 and is used to wash and groom the pet inside the washing and grooming chamber 11. The washing and grooming mechanism 2 may include a spray device, a detergent supply device, and a blower. The washing and grooming mechanism 2 provides automatic or semi-automatic washing and grooming functions for the pet, and may include operations such as spray rinsing, detergent application, and drying to achieve cleaning and care for the pet.

[0036] The filter box 3 is installed at the bottom of the washing and care box 1. The filter box 3 includes a filter screen 31 and a filter chamber 32. The filter screen 31 is housed within the filter chamber 32. The water outlet 13 and the drain outlet 14 are located on opposite sides of the filter screen 31. The water outlet 13, filter chamber 32, and drain outlet 14 are sequentially connected along the flow direction of the washing and care wastewater. The filter box 3 can be a box-shaped container made of plastic or stainless steel and can be installed at the bottom of the washing and care box 1 in a fixed or detachable manner. If it is detachable, it is easy to remove and clean. The filter screen 31 can be made of stainless steel wire mesh, nylon filter screen, or perforated plate, and its filtration accuracy is determined according to the particle size of pet hair and debris. The filter screen 31 divides the filter chamber 32 into an inlet area near the water outlet 13 and an outlet area near the drain outlet 14. The wastewater containing pet hair, dander, and impurities generated during the washing and care process is filtered, and solid debris is trapped on the side of the filter screen 31 near the outlet 13, so that the filtered wastewater is discharged from the drain outlet 14, preventing hair and debris from clogging the drain pipe or polluting the environment.

[0037] The scraper 4 is movably disposed within the filter chamber 32 and located on the side of the filter screen 31 near the outlet 13. The scraper 4 is used to scrape debris on the filter screen 31 to the edge of the filter screen 31. The scraper 4 can move in a rotating or linear manner. If it is set to linear movement, its movement direction can be reciprocating along the length of the filter screen 31. Guide blocks can be provided at both ends of the scraper 4 to cooperate with the guide grooves on the side wall of the filter chamber 32. By moving the scraper 4, the surface of the filter screen 31 is cleaned, and pet hair and debris trapped on the surface of the filter screen 31 are scraped to the edge of the filter screen 31 or scraped away from the surface of the filter screen 31, preventing debris from accumulating on the surface of the filter screen 31 and causing a decrease in filtration efficiency or clogging.

[0038] The drive end of the first drive assembly 5 is connected to the scraper 4, and the first drive assembly 5 is used to drive the scraper 4 to move. The first drive assembly 5 can be driven by an electric push rod or a cylinder. The telescopic end of the electric push rod or cylinder is directly connected to the scraper 4, and the scraper 4 is driven to reciprocate through telescopic movement. Under the drive of the first drive assembly 5, the scraper 4 can automatically reciprocate along the surface of the filter screen 31 in the filter chamber 32, thereby cleaning the filter screen 31.

[0039] To use, open the door 12 and place the pet into the washing chamber 11 through the opening. Then close the door 12 and start the washing mechanism 2. The washing mechanism 2 will then clean and dry the pet. Wastewater containing pet hair, dander, and dirt generated during the washing process will be discharged through the outlet 13 on the bottom wall of the washing chamber 11 into the filter chamber 32 of the filter box 3. After entering the filter chamber 32, the wastewater flows through the filter screen 31 under gravity. Solid impurities in the wastewater are trapped on the side of the filter screen 31 near the outlet 13. The filtered clear liquid continues to flow downward through the filter screen 31 and is discharged out of the washing box 1 through the drain 14. The first drive assembly 5 drives the scraper 4 to reciprocate along the surface of the filter screen 31 within the filter chamber 32. The side of the scraper 4 closest to the filter screen 31 abuts against the surface of the filter screen 31. During the movement, it scrapes up hair and debris attached to the filter screen 31 and pushes them to the edge area of ​​the filter screen 31, keeping the mesh openings in the central area of ​​the filter screen 31 clear, maintaining the filtration flow, and allowing the filter screen 31 to continue working. After the bathing and grooming is complete, open the door 12 and take out the pet.

[0040] The pet washing box 1 is equipped with a washing chamber 11, a door 12, a water outlet 13, and a drain outlet 14. The washing chamber 11 is used to hold the pet. The door 12 is located on the side wall of the washing box 1 and is used to open or close the opening of the washing chamber 11. The water outlet 13 is located on the bottom wall of the washing chamber 11. The drain outlet 14 is located on the side wall of the washing box 1. A washing mechanism 2 is installed in the washing box 1 and is used to wash the pet in the washing chamber 11. The operator can open the door 12 to put the pet into the washing chamber 11, close the door 12, and start the washing mechanism 2 to clean the pet. Wastewater containing pet hair and dander generated during the washing process can be discharged from the bottom wall of the washing chamber 11 through the water outlet 13 under gravity, preventing wastewater from accumulating in the washing chamber 11 and affecting the washing effect or causing bacterial growth. This provides a wastewater source and directional flow path for subsequent filtration treatment, allowing wastewater containing pet hair and dander to be collected and guided to the filtration stage.

[0041] The filter box 3 is installed at the bottom of the washing and care tank 1. The filter box 3 is equipped with a filter screen 31 and a filter chamber 32. The filter screen 31 is housed in the filter chamber 32. The water outlet 13 and the drain outlet 14 are located on opposite sides of the filter screen 31. The water outlet 13, the filter chamber 32 and the drain outlet 14 are connected in sequence along the flow direction of the washing and care wastewater. Thus, the wastewater containing impurities discharged from the water outlet 13 enters the filter chamber 32 under the action of gravity and flows through the filter screen 31. The solid impurities in the wastewater are trapped by the filter screen 31 on the side of the filter screen 31 near the water outlet 13. The filtered clear liquid continues to flow downward through the filter screen 31 and is discharged from the washing and care tank 1 through the drain outlet 14, thus realizing the filtration of washing and care wastewater.

[0042] The scraper 4 is movably disposed within the filter chamber 32 and located on the side of the filter screen 31 near the outlet 13. The scraper 4 is used to scrape debris on the filter screen 31 to its edge. The drive end of the first drive assembly 5 is connected to the scraper 4, and the first drive assembly 5 is used to drive the scraper 4 to move. Thus, under the action of the first drive assembly 5, the scraper 4 can scrape up hair and debris trapped on the surface of the filter screen 31 and push it to the edge area of ​​the filter screen 31 during its movement, keeping the mesh openings in the central area of ​​the filter screen 31 unobstructed. The cleaning action of the scraper 4 can be performed periodically or continuously during the filtration process, achieving automatic cleaning without disassembling the filter screen 31. This reduces the frequency and maintenance costs of manual cleaning of the filter screen 31, and the filter screen 31 is less prone to clogging during the filtration of washing wastewater.

[0043] Preferably, a self-service pet grooming device further includes a collection box 6, which is detachably installed in the filter chamber 32 and located below the edge of the filter screen 31. The collection box 6 is used to collect debris scraped to the edge of the filter screen 31 by the scraper 4. The collection box 6 can be a box-shaped container made of plastic or stainless steel, with its opening facing downwards from the edge of the filter screen 31. After the scraper 4 pushes the hair and debris on the filter screen 31 to the edge of the filter screen 31, the debris falls into the collection box 6 located below the edge of the filter screen 31 under the action of gravity and is trapped inside the collection box 6. The collection box 6 can be detachably installed in the filter chamber 32 via a slide rail, buckle, or slot for easy removal, emptying of debris, and cleaning. Filter holes can be provided on the bottom or side wall of the collection box 6 to allow a small amount of liquid carried out with the debris to flow to the drain outlet 14. By setting up the collection box 6, the scraped debris is prevented from accumulating disorderly in the filter chamber 32 or re-attaching to the surface of the filter screen 31 with the water flow. At the same time, it is easy to remove and clean it regularly, preventing the debris from accumulating in the filter chamber 32 for a long time, fermenting and producing odors or breeding bacteria. It also prevents the scraped debris from flowing back to the surface of the filter screen 31 with the liquid and affecting the filtration effect.

[0044] Preferably, the collection box 6 is slidably mounted on the side wall of the washing and care tank 1 and extends into the filter chamber 32. The collection box 6 is slidably connected to the filter box 3. A handle 61 is provided at the end of the collection box 6 away from the filter chamber 32, and the handle 61 is located outside the washing and care tank 1. The collection box 6 can be slidably connected to the filter box 3 via a slide rail or slide groove. A guide structure is provided on the side wall or bottom of the filter box 3, and a sliding element that slides with the guide structure is provided on the bottom surface or side wall of the collection box 6. An opening can be provided on the side wall of the washing and care tank 1, which connects to the filter chamber 32. The shape of the opening corresponds to the cross-sectional shape of the collection box 6, and the collection box 6 is slidably connected to the side wall of the washing and care tank 1 through the opening. A sealing ring or brush seal can be provided at the opening to prevent sewage from leaking from the gaps. The handle 61 is fixed to the end of the collection box 6 located outside the washing and care tank 1. The handle 61 can be U-shaped, L-shaped, or concave to facilitate gripping and applying force. The surface of the handle 61 can be provided with anti-slip texture or covered with rubber to improve grip comfort. The operator simply needs to grasp the handle 61 located on the outside of the washing and care box 1 and pull it outwards. The collection box 6 will then slide out of the filter chamber 32 along the sliding direction, making it easy to empty the hair and debris trapped inside. After cleaning, the collection box 6 can be pushed back into the filter chamber 32 until it is in place, and the machine can continue to be used. The operator does not need to open the washing and care box 1 or reach into the filter chamber 32 to remove the collection box 6 and empty the debris, simplifying the cleaning process and improving ease of use.

[0045] Preferably, at least two collection boxes 6 are provided, and the at least two collection boxes 6 are respectively located on opposite sides of the filter screen 31 along the horizontal direction. The scraper 4 can be correspondingly configured to reciprocate linearly. The at least two collection boxes 6 are located at both ends along the moving direction of the scraper 4, and their structures are identical. They can all be detachably installed in the filter chamber 32 via slide rails or buckles, and are respectively installed through the side wall of the washing and care box 1. Each has a handle 61 located outside the washing and care box 1. When the scraper 4 reciprocates along the surface of the filter screen 31, moving in one direction pushes the debris into the collection box 6 on that side, and moving in the other direction pushes the debris into the collection box 6 on the other side, thereby improving the collection efficiency of the debris and extending the single cleaning cycle.

[0046] Preferably, the washing and care mechanism 2 includes a spray pipe 21, a hot air pipe 22, and a second drive assembly 23. Both the spray pipe 21 and the hot air pipe 22 are located within the washing and care chamber 11.

The spray pipe 21 and the hot air pipe 22 are fixed to the connecting block 233 by pipe clamps or brackets. Motor 231 drives the first lead screw 232 to rotate. The first lead screw 232 drives the connecting block 233 to slide axially along the guide rod 234 through the threaded pair. The connecting block 233 drives the spray pipe 21 and the hot air pipe 22 to move back and forth synchronously, realizing dynamic coverage of spraying and drying.

[0049] Preferably, the second drive assembly 23 is connected to the first drive assembly 5 via a central transmission mechanism 7. The central transmission mechanism 7 can take various forms, such as including a drive gear, a driven gear, and a drive shaft. The drive gear is installed at the power output end of the second drive assembly 23, the driven gear is installed at the power input end of the first drive assembly 5, and the drive shaft connects the drive gear and the driven gear to achieve torque transmission. The central transmission mechanism 7 can also use a synchronous belt drive or a chain drive to transmit power from the second drive assembly 23 to the first drive assembly 5. The central transmission mechanism 7 can also use a worm gear drive or a linkage drive to change the direction and speed ratio of power transmission. By setting the central transmission mechanism 7, the second drive assembly 23 can synchronously transmit power to the first drive assembly 5, enabling the operation of the washing and care mechanism 2 to be linked with the cleaning action of the scraper 4. That is, while the washing and care mechanism 2 sprays and cleans the pet, the scraper 4 simultaneously cleans the filter 31, eliminating the need for a separate drive source for the scraper 4, reducing energy consumption, equipment costs, and failure rate.

[0050] Preferably, the first drive assembly 5 includes a slide rod 51 and a second lead screw 52. The slide rod 51 is connected to the scraper 4 near the electrical appliance mounting cavity 15 and extends axially along the guide rod 234. The slide rod 51 is slidably inserted through the side wall of the filter cavity 32 and extends out of the filter box 3. The second lead screw 52 is rotatably installed in the washing and care box 1. The second lead screw 52 extends axially along the slide rod 51 and is screwed to the slide rod 51. The central transmission mechanism 7 includes a drive wheel 71 and a driven wheel 72. Both the drive wheel 71 and the driven wheel 72 are located inside the electrical appliance mounting cavity 15. The drive wheel 71 is driven and sleeved outside the first lead screw 232, and the driven wheel 72 is driven and sleeved outside the second lead screw 52. The drive wheel 71 is driven and connected to the driven wheel 72. The slide rod 51 is a long, strip-shaped rod, which can be made of metal or engineering plastic. One end is connected to the scraper 4 near the electrical installation cavity 15 (i.e., the connecting end where the scraper 4 extends to the outside of the filter cavity 32), and the other end extends axially along the guide rod 234 and passes through the side wall of the filter cavity 32. A sealing ring or sealing sleeve is provided where the slide rod 51 passes through the side wall of the filter cavity 32 to prevent sewage from leaking along the slide rod 51. The second lead screw 52 is rotatably mounted on the bottom of the washing and care tank 1 or inside the electrical installation cavity 15 through a bearing seat. Its axis is parallel to the axis of the slide rod 51 and is screwed into the slide rod 51. The driving wheel 71 can be connected to the end of the first lead screw 232 by a key or a set screw, and the driven wheel 72 can be connected to the end of the second lead screw 52 by a key or a set screw. The driving wheel 71 and the driven wheel 72 can be driven by gear meshing, synchronous belt drive, or chain drive. The length of the filter chamber 32 can be set to be less than the length of the washing and care chamber 11. By adjusting the transmission ratio between the drive wheel 71 and the driven wheel 72, the rotational speed of the second lead screw 52 and the rotational speed of the first lead screw 232 are kept in a corresponding proportion. This ensures that when the connecting block 233 completes a full stroke from one end to the other in the washing and care chamber 11, the scraper 4 also completes a full stroke from one end to the other in the filter chamber 32. This allows the movement of the scraper 4 to be synchronized with the movement of the spray pipe 21 and the hot air pipe 22, ensuring that the reciprocating motion of the washing and care mechanism 2 and the cleaning action of the scraper 4 are coordinated.

[0051] Preferably, the central transmission mechanism 7 further includes a transmission chain 73, through which the driving wheel 71 is connected to the driven wheel 72. Both the driving wheel 71 and the driven wheel 72 are sprockets, with teeth on their outer circumference matching the transmission chain 73. The transmission chain 73 is a bushing roller chain or a toothed chain. The driving wheel 71 is fixedly connected to the end of the first lead screw 232 via a key, and the driven wheel 72 is fixedly connected to the end of the second lead screw 52 via a key. The transmission chain 73 surrounds the outer circumference of the driving wheel 71 and the driven wheel 72, forming a closed transmission circuit. A protective cover may be provided on the outer side of the transmission chain 73 to prevent foreign objects from entering the meshing area and to prevent lubricating oil from splashing and contaminating the electrical mounting cavity 15. The drive chain 73 enables flexible power transmission between the drive wheel 71 and the driven wheel 72, allowing the rotational power of the first lead screw 232 to be accurately transmitted to the second lead screw 52. At the same time, it allows for a certain center distance deviation or installation error between the drive wheel 71 and the driven wheel 72, reducing the requirements for assembly accuracy and facilitating the installation and maintenance of the equipment.

[0052] As an alternative configuration, the transmission chain 73 can be replaced with a synchronous belt. Synchronous belt drives have the advantages of smooth transmission, no lubrication required, and low noise, making them suitable for clean environments. A tensioning pulley can be installed between the transmission chain 73 and the driving pulley 71 and the driven pulley 72 to adjust the tension of the transmission chain 73 and ensure the accuracy and stability of the transmission.

[0053] Preferably, the filter screen 31 has a plurality of first filter holes 311, and the collection box 6 has a plurality of second filter holes 62; the diameter of each second filter hole 62 is less than or equal to the diameter of each first filter hole 311. The first filter holes 311 are through holes on the filter screen 31 used for filtering sewage, and their diameter is determined according to the filtration accuracy. The second filter holes 62 are through holes opened in the side wall or bottom of the collection box 6, and their diameter is less than or equal to the diameter of the first filter holes 311. The number and distribution of the second filter holes 62 can be determined according to the structure of the collection box 6, for example, they can be evenly distributed at the bottom and lower part of the side wall of the collection box 6. After the scraper 4 scrapes the debris on the surface of the filter screen 31 to the edge of the filter screen 31 and falls into the collection box 6, the residual liquid carried in the debris seeps out of the collection box 6 through the second filter hole 62, flows back to the filter chamber 32 and is discharged through the drain outlet 14, thereby achieving further dehydration and reduction of the debris; at the same time, the pore diameter of the second filter hole 62 is less than or equal to the pore diameter of the first filter hole 311, ensuring that any fine particles that can pass through the first filter hole 311 into the collection box 6 will not leak out of the collection box 6, avoiding the collected debris from re-entering the filter chamber 32 and causing secondary pollution.
