Description

Technical Field

[0001] This application relates to the field of cat litter box technology, and more particularly to a water-circulating cleaning cat litter box. Background Technology

[0002] As living standards continue to improve, more and more families are choosing pets for daily companionship, especially in economically developed cities where the proportion of pet owners is higher. However, due to the limited living space per capita and restrictions on pets going out in economically developed cities, more pet owners tend to prefer felines, which do not require much space to roam. Felines require specialized litter boxes, which must be cleaned and disposed of regularly.

[0003] Currently, the main way to solve the problem of cat excretion in pet cats is through litter boxes. However, existing litter boxes usually do not have a litter cleaning function, which means that cats can urinate or defecate on the litter. The surface of the litter is contaminated with feces and excrement, which causes the litter to produce a noticeable odor, making both the owner and the cat uncomfortable. After a few days of use, the contaminated litter needs to be discarded and replaced with new litter, resulting in a lot of waste and environmental problems, as well as increased costs. This is undoubtedly a major pain point for cat owners. Utility Model Content

[0004] The purpose of this application is to provide a water-circulating cleaning litter box, which aims to solve the technical problem that existing litter boxes cannot clean the litter.

[0005] To achieve the above objectives, the technical solution of this application provides a water-circulating litter box for cleaning cat litter, comprising:

[0006] The basin has a sitting and lying space for placing cat litter for cats to defecate in, and the inner wall of the sitting and lying space is provided with filter holes for filtering out water.

[0007] A screening component for screening and discharging feces from the sitting / lying space, the screening component being movably mounted on the basin body;

[0008] A water washing chamber is disposed within the basin.

[0009] The feeding section is located between the sitting / lying space and the washing chamber, for discharging cat litter from the sitting / lying space into the washing chamber.

[0010] The circulating cleaning assembly includes a cleaning pump and a circulating pipe. The inlet of the cleaning pump is connected to the washing chamber, and the outlet of the cleaning pump is connected to the sitting / lying space through the circulating pipe.

[0011] As can be seen from the above technical solution, the water-circulating litter box of this application discharges the litter and water in the sitting and lying space into the water washing chamber through the feeding part. The washing pump then draws the litter and water from the water washing chamber, which flow along the circulation pipe and discharges it back onto the sitting and lying space. The water in the sitting and lying space is filtered out through the filter holes, thereby realizing the circulation and washing of the litter along with the water flow. This removes the small amount of excrement and obvious odor adhering to the surface of the litter, allowing the litter to be reused, saving the cost of using litter, and providing a clean and hygienic experience with a better user experience.

[0012] Furthermore, the washing chamber is located below the sitting / lying space, and there are multiple filter holes, which are disposed between the sitting / lying space and the washing chamber, so as to filter the water in the sitting / lying space into the washing chamber through the filter holes. The washing chamber is provided with a drain outlet.

[0013] Furthermore, the basin is provided with a collection cavity, so that the feces in the sitting and lying space can be screened and discharged into the collection cavity by the screening component.

[0014] Furthermore, the two ends of the screening component are movably connected to the opposite side walls of the sitting / lying space, so that the screening component can move from one end of the sitting / lying space to the other end of the sitting / lying space to screen and discharge the feces in the sitting / lying space.

[0015] Furthermore, the screening component includes a support member and a screening part. The screening part is disposed on the support member. A guide structure is provided between the two ends of the support member and the opposite side walls of the sitting and lying space, so as to guide the screening component to move along a preset path in the sitting and lying space through the guide structure, thereby screening and discharging feces.

[0016] Furthermore, the screening section includes a plurality of screening teeth, which are spaced apart along the length of the support to form a gap between two adjacent screening teeth for passing through cat litter, and the screening teeth extend toward the bottom wall of the sitting and lying space so that the ends of the screening teeth are close to or in contact with the bottom wall of the sitting and lying space.

[0017] Furthermore, the screening component also includes a drive unit, which includes a drive motor and a transmission mechanism. The transmission mechanism is disposed between the support member and the side wall of the sitting / lying space, so that the drive motor drives the screening component to move along a preset path of the guide structure through the transmission mechanism.

[0018] Furthermore, the guide structure includes a guide groove and a sliding part. The guide groove is disposed on the side wall of the sitting / lying space, and the sliding part is disposed on the end of the support member. The sliding part is slidably disposed in the guide groove. The guide groove extends in a straight line or curves in an arc so that the distance between the guide groove and the bottom wall of the sitting / lying space remains consistent along a preset path.

[0019] Furthermore, it also includes a drying assembly, which includes a drying channel, a heater, and a fan unit, so that the air blown out by the fan unit is heated by the heater and then blown into the sitting and lying space to dry the cleaned cat litter.

[0020] Furthermore, the feeding section includes a drive motor, a motion mechanism, and a cover plate. A first opening is formed in the inner wall of the sitting / lying space. The cover plate is movably positioned over the first opening. The drive motor, through the motion mechanism, drives the cover plate to open or close the first opening, so that when the first opening is open, cat litter and water in the sitting / lying space are fed through the first opening into the washing chamber; and / or

[0021] The litter box also includes a water injection assembly, a first water level sensor, and a circuit board. The water injection assembly includes a water injection pipe and an inlet solenoid valve to add water to the washing chamber and / or the sitting / lying space by connecting an external water source through the water injection pipe. The inlet solenoid valve is disposed on the water injection pipe. The first water level sensor is used to detect the water level in the washing chamber and / or the sitting / lying space so that the circuit board controls the inlet solenoid valve to close the water injection pipe when the water level detected by the first water level sensor reaches a preset value.

[0022] The technical solution of this application provides a water-circulating litter box for cleaning cat litter, including:

[0023] The basin has a sitting and lying space for placing cat litter for cats to defecate in, and the inner wall of the sitting and lying space is provided with filter holes for filtering out water.

[0024] A screening component for screening and discharging feces from the sitting / lying space, the screening component being movably mounted on the basin body;

[0025] A water washing chamber is disposed within the basin.

[0026] The circulating cleaning assembly includes a cleaning pump and a circulating pipe. The inlet of the cleaning pump is connected to the washing chamber, and the outlet of the cleaning pump is connected to one end of the circulating pipe. The other end of the circulating pipe is located above or on the side wall of the sitting and lying space, and one or more spray holes are provided at the other end of the circulating pipe so that the cleaning pump draws water from the washing chamber and cleans the cat litter in the sitting and lying space through the circulating pipe.

[0027] As can be seen from the above technical solution, the water circulation cleaning litter box of this application uses a cleaning pump to draw water from the water washing chamber and clean the litter in the sitting and lying space through a circulation pipe. The water in the sitting and lying space is filtered into the water washing chamber through a filter hole, thereby realizing water circulation to wash the litter, removing a small amount of excrement and obvious odor from the surface of the litter. This allows the litter to be reused, saving the cost of using the litter, making it clean and hygienic, and providing a better user experience.

[0046] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0047] Please refer to the following: Figures 1 to 11 This embodiment provides a water-circulating litter box, including a basin body 100, a screening component 200, a water washing chamber 120, a feeding section 300, and a circulating cleaning component. The basin body 100 has a sitting / lying space 110 for placing cat litter for cats to defecate in, and the inner wall of the sitting / lying space 110 is provided with filter holes 111 for filtering out water. The screening component 200 is used to screen and discharge feces in the sitting / lying space 110, and the screening component 200 is movably disposed on the basin body 100. The water washing chamber 120... The litter box 100 is located inside the basin; the feeding part 300 is located between the sitting / lying space 110 and the washing chamber 120 to feed cat litter from the sitting / lying space 110 into the washing chamber 120; the circulating cleaning assembly includes a cleaning pump 420 and a circulating pipe 410. The inlet of the cleaning pump 420 is connected to the washing chamber 120, and the outlet of the cleaning pump 420 is connected to the sitting / lying space 110 through the circulating pipe 410. The cleaning pump 420 adopts the Sanyo washing machine XQB55-496 impeller water pump assembly.

[0048] As can be seen from the above technical solution, the water circulation cleaning litter box of this embodiment discharges the litter and water in the sitting and lying space 110 into the water washing chamber 120 through the feeding part 300. The cleaning pump 420 draws the litter and water in the water washing chamber 120, which flows along the circulation pipe 410 and is then discharged back onto the sitting and lying space 110. The water in the sitting and lying space 110 is filtered out through the filter hole 111, thereby realizing the circulation and washing of the litter along with the water flow to remove the small amount of excrement and obvious odor adhering to the surface of the litter. This allows the litter to be reused, saving the cost of using the litter. It is clean and hygienic, and provides a good user experience.

[0049] In this embodiment, the washing chamber 120 is located below the sitting / lying space 110. There are multiple filter holes 111, and the filter holes 111 are arranged between the sitting / lying space 110 and the washing chamber 120 to filter the water in the sitting / lying space 110 into the washing chamber 120 through the filter holes 111. The washing chamber 120 is provided with a drain outlet so that after the cat litter is circulated and washed multiple times, the feeding part 300 is closed, and the water in the sitting / lying space 110 is discharged into the washing chamber 120 through the filter holes 111, thereby retaining the cat litter in the sitting / lying space 110 for subsequent use.

[0050] Specifically, the basin 100 is provided with a storage cavity 130, so that the cat's feces in the sitting and lying space 110 can be screened and discharged into the storage cavity 130 for centralized storage through the screening component 200, thereby improving the practicality and convenience of the product.

[0051] Furthermore, the two ends of the screening component 200 are movably connected to the opposite side walls of the sitting / lying space 110, so that the screening component 200 can move from one end of the sitting / lying space 110 to the other end of the sitting / lying space 110 to screen and discharge feces in the sitting / lying space 110. The screening component 200 includes a support member 210 and a screening part. The screening part is disposed on the support member 210. The two ends of the support member 210 are provided with a guide structure between them and the opposite side walls of the sitting / lying space 110, so as to guide the screening component 200 to move along a preset path in the sitting / lying space 110 to screen and discharge feces. The structure is simple, stable and reliable. In this way, the cat feces in the sitting / lying space 110 are screened and discharged first, which facilitates the water circulation and cleaning of the cat litter in the sitting / lying space 110.

[0052] Preferably, the screening section includes a plurality of screening teeth 270, which are spaced apart along the length of the support member 210 to form a gap between adjacent screening teeth 270 for cat litter to pass through. The screening teeth 270 extend toward the bottom wall of the sitting and lying space 110 so that the ends of the screening teeth 270 are close to or in contact with the bottom wall of the sitting and lying space 110. In this way, since the cat litter particles are small enough to pass through the gap between adjacent screening teeth 270, the cat litter remains in the sitting and lying space 110 during the operation of the screening teeth 270. However, the cat feces are larger and cannot pass through the gap between adjacent screening teeth 270, so they are pushed by the screening teeth 270 and fall into the collection cavity 130 for centralized collection, thereby realizing the screening and discharge of cat feces in the sitting and lying space 110.

[0053] In this embodiment, the screening component 200 also includes a drive unit, which includes a drive motor 220 and a transmission mechanism. The transmission mechanism is disposed between the support member 210 and the side wall of the sitting and lying space 110, so that the drive motor 220 drives the screening component 200 to move along the preset path of the guide structure through the transmission mechanism, thereby realizing the automatic screening of cat feces in the sitting and lying space 110 by driving the screening claw 270 to operate. The product has a high degree of intelligence and automation and is easy to use.

[0054] Specifically, the guiding structure includes a guide groove 291 and a sliding part. The guide groove 291 is disposed on the side wall of the sitting and lying space 110, and the sliding part is disposed on the end of the support member 210. The sliding part is slidably disposed in the guide groove 291. The guide groove 291 extends in a straight line or curves so that the distance between the guide groove 291 and the bottom wall of the sitting and lying space 110 remains consistent along a preset path. This arrangement ensures that the end of the screening claw 270 is close to or in contact with the bottom wall of the sitting and lying space 110 during the operation of the screening claw 270, thereby preventing cat feces from leaking out during screening and remaining in the sitting and lying space 110, affecting the cat litter cleaning effect, and thus improving the practicality and stability of the product.

[0055] Furthermore, the transmission mechanism includes a transmission shaft 230, gears 240, and racks 280. A drive motor 220 is disposed within a support member 210. The support member 210 includes an interlocking upper and lower shell and is shaft-shaped. The transmission shaft 230 is rotatably mounted on the support member 210, with both ends of the transmission shaft 230 extending from both ends of the support member 210. The output shaft of the drive motor 220 is connected to the transmission shaft 230 via a transmission belt. Gears 240 are respectively disposed at both ends of the transmission shaft 230, and racks 280 are respectively disposed at the ends of the sitting / lying space 110. The inner walls of the guide grooves 291 on both sides are opposite each other, and the gear 240 meshes with the rack 280 for transmission. The rack 280 extends along the length of the guide groove 291 so that the drive shaft 230 is driven to rotate by the drive motor 220, which in turn drives the gear 240 to rotate along the rack 280. Under the guidance of the guide structure, the screening claw 270 moves from one end of the sitting and lying space 110 to the other end of the sitting and lying space 110, thereby screening and discharging the feces mixed in the cat litter into the collection cavity 130 for centralized collection. The collection cavity 130 is installed at the other end of the sitting and lying space 110.

[0056] The sliding part is a roller 260 structure, and the sliding part and the transmission shaft 230 are spaced apart. The sliding part and the gear 240 are both housed in the guide groove 291. The inner wall of the guide groove 291 is provided with a transmission groove 292, which extends along the length of the guide groove 291. The width of the transmission groove 292 is smaller than the width of the guide groove 291. The end of the transmission shaft 230 is fitted with a bearing 250 so that the bearing 250 can be movably installed in the transmission groove 292 to improve the smoothness and stability of the operation of the screening component 200.

[0057] In this embodiment, the top of the storage cavity 130 is open, and a top cover 131 is rotatably installed on the top of the storage cavity 130 to cover the top opening of the storage cavity 130. At least one side of the top cover 131 extends toward the sitting / lying space 110 to form a wing plate 132, so that when the screening component 200 moves to screen feces, the support member 210 abuts against the wing plate 132 to lift the top cover 131, thereby opening the storage cavity 130 and pushing the feces into the storage cavity 130 for storage. The structure is simple and easy to use.

[0058] Specifically, the washing chamber 120 is connected to the storage chamber 130, and a filter screen 121 is provided between the washing chamber 120 and the storage chamber 130 to prevent the cat litter in the washing chamber 120 from being accidentally discharged when the sewage in the washing chamber 120 flows into the storage chamber 130. A sewage pump 510 is provided in the sewage chamber, and a sewage outlet is provided at the bottom of the sewage chamber. The sewage outlet is connected to a sewage discharge pipe 520. A solenoid valve can be installed on the sewage discharge pipe 520 to control automatic opening or closing, so that the sewage pump 510 can run to discharge the sewage in the sewage chamber and the feces dissolved in the sewage through the sewage discharge pipe 520.

[0059] In this embodiment, the litter box also includes a drying assembly, which includes a drying channel 610, a heater 620, and a fan unit 630. The air blown out by the fan unit 630 is heated by the heater 620 and then blown into the sitting / lying space 110 to dry the cleaned litter. One end of the drying channel 610 is connected to the washing chamber 120, and the other end of the drying channel 610 extends upward. The heater 620 and the fan unit 630 are installed at the other end of the drying channel 610 so that after the sewage in the washing chamber 120 is discharged, the hot air in the drying channel 610 is blown upward into the sitting / lying space 110 through the filter holes 111 to dry the cleaned litter, making it easier for the pet cat to continue using the litter.

[0060] Furthermore, the feeding section 300 includes a drive motor 320, a motion mechanism, and a cover plate 310. A first opening 112 is provided on the inner wall of the sitting / lying space 110. The cover plate 310 is movably positioned over the first opening 112. The drive motor 320 drives the cover plate 310 to move via the motion mechanism, thereby opening or closing the first opening 112. When the first opening 112 is open, cat litter and water in the sitting / lying space 110 are fed through the first opening 112 into the washing chamber 120. When water flows through the washing chamber 120... When water flows into the sitting / resting space 110 through the filter hole 111 and the first opening 112 is open, the cleaning pump 420 draws water from the washing chamber 120 and discharges it into the sitting / resting space 110 through the circulation pipe 410. The end of the circulation pipe 410 is connected to the sitting / resting space 110 through the through-hole 113 on the side wall of the sitting / resting space 110. The cat litter in the sitting / resting space 110 flows into the washing chamber 120 along with the water flow through the first opening 112, and then the cleaning pump 420 draws water and cat litter from the washing chamber 120 for circulation. The litter is discharged into the sitting / lying space 110, where it is washed by the circulating water. The friction between the litter and the blades of the washing pump 420 also helps to clean the litter. This water circulation and washing process is repeated multiple times to thoroughly clean the litter surface. Then, the cover 310 of the discharge section 300 closes the first opening 112, preventing the litter from flowing into the washing chamber 120 and keeping it trapped within the sitting / lying space 110. Water in the sitting / lying space 110 can pass through the filter holes 11. 1. The litter flows back into the washing chamber 120. Through multiple cycles of the cleaning pump 420, the litter and water in the washing chamber 120 are extracted and discharged into the sitting and lying space 110. This allows the litter in the washing chamber 120 to be re-displaced into the sitting and lying space 110. In actual testing, the applicant found that almost all the litter in the washing chamber 120 can be replaced into the sitting and lying space 110. Even if a few litter particles remain in the washing chamber 120, they can be replaced into the sitting and lying space 110 for continued use during the next litter cleaning.

[0061] After the cat litter is cleaned, the wastewater pump 510 draws out the wastewater from the collection chamber 130 and discharges it through the wastewater discharge pipe 520. During the discharge of wastewater from the collection chamber 130, the wastewater in the washing chamber 120 continuously flows into the collection chamber 130 for centralized discharge, and the wastewater in the sitting and lying space 110 flows into the washing chamber 120 through the filter hole 111 and is also discharged. In this way, the surface of the cat litter can be cleaned. Of course, water can be added again to circulate and clean the cat litter multiple times to improve the cleaning effect.

[0062] Specifically, the cover plate 310 has shaft ends 311 on both opposite sides, and the first opening 112 has mounting holes on both opposite side walls, so that the shaft ends 311 can be inserted into the mounting holes to allow the cover plate 310 to rotatably cover the first opening 112. The cover plate 310 is provided with a support frame 340, and the support frame 340 has a strip-shaped movable groove 350. The motion mechanism includes a lead screw 330 and a connecting member 360. The end of the connecting member 360 is provided with a guide rod 370, which is movably inserted into the strip-shaped movable groove 350. The connecting member 360 has a threaded hole. The lead screw 330 is connected to the output shaft of the drive motor 320, and the lead screw 330 is connected to the threaded hole so that the drive motor 320 drives the motor. The lead screw 330 rotates, and under the helical force of the lead screw 330 and the threaded hole, the connector 360 is driven to rise or fall along the lead screw 330. This causes the guide rod 370 of the connector 360 to press down or lift the support frame 340, thereby driving the cover plate 310 to rotate and open or close the first opening 112. The circuit board controls the rotation angle of the cover plate 310 according to the drive motor 320, thereby controlling the size of the opening of the first opening 112. This controls the proportion of cat litter in the sitting and lying space 110 flowing into the washing chamber 120 through the first opening 112, so as to avoid too much cat litter flowing into the washing chamber 120 at once and being drawn into the cleaning pump 420, causing jamming and affecting the cat litter cleaning effect. The structural design is stable and reliable.

[0063] In this embodiment, the litter box also includes a water injection component, a first water level sensor, and a circuit board. The circuit board uses an STM32 MCU as the main controller. The first water level sensor and the solenoid valve can use existing functional components. The water injection component includes a water injection pipe 710 and an inlet solenoid valve 720, which connects to an external water source through the water injection pipe 710 to add water to the washing chamber 120 and / or the sitting / lying space 110. The inlet solenoid valve 720 is disposed on the water injection pipe 710. The first water level sensor is used to detect the water level in the washing chamber 120 and / or the sitting / lying space 110. The water level is controlled by the first water level sensor to reach a preset value, thereby controlling the water inlet solenoid valve 720 to close the water inlet pipe 710. One end of the water inlet pipe 710 is connected to the receiving cavity 130, so that water is added to the receiving cavity 130 first through the water inlet pipe 710. After the water level in the receiving cavity 130 rises, it flows into the washing cavity 120 and the sitting and lying space 110. Under normal circumstances, the first water level sensor can detect and control the water level in the sitting and lying space 110 to prevent the washing water from overflowing, thereby improving the safety and reliability of the product.

[0064] Furthermore, an infrared sensor 140 is installed in the sitting / lying space 110. The sensor can be a BGX-35N diffuse reflection sensor from Boyi Precision Technology Co., Ltd., to detect whether there is a pet cat in the sitting / lying space 110, so as to ensure that the cat litter cleaning program is started only when the pet cat is not in the sitting / lying space 110.

[0065] When using, such as Figure 1 As shown, in the initial daily state, the screening component 200 is located at one end of the sitting / lying space 110, which contains many cat litter pellets for the cat to use for excretion. When the cat litter needs to be cleaned, the screening teeth 270 of the screening component 200 first move from one end of the sitting / lying space 110 to the other end, thereby screening out the cat feces mixed in the litter. Figure 2 As shown, the litter box is in the feces-filtering state, so that when the filtering component 200 moves to the other end of the adjacent sitting / lying space 110, the top cover 131 is lifted by the support member 210 abutting against the wing plate 132. Figure 3 As shown, the storage cavity 130 is then opened, and the cat's feces are pushed into the storage cavity 130 for centralized collection by the screening claws 270, as shown. Figure 4 As shown, the inlet solenoid valve 720 is then opened, and some water is added to the collection chamber 130 through the water injection pipe 710. Then, the sewage pump 510 is started. The rotating blades of the sewage pump 510 agitate the feces in the collection chamber 130, grinding or breaking them up. An existing water pump with a feces-grinding function can be used for the sewage pump 510. This dissolves the ground feces particles in water, which are then discharged through the sewage discharge pipe 520. Afterward, cleaning water is added for water circulation to clean the cat litter. Figure 5 As shown, when the amount of cleaning water added reaches a preset value, the cleaning pump 420 is activated, and the cover plate 310 of the feeding section 300 opens the first opening 112, allowing the cat litter in the sitting / lying space 110 to flow into the washing chamber 120 through the first opening 112. The cleaning pump 420 then draws water and cat litter from the washing chamber 120 and discharges them into the sitting / lying space 110 through the circulation pipe 410. The water in the sitting / lying space 110 can flow into the washing chamber 120 through the filter holes 111, and the cat litter in the sitting / lying space 110 can also flow into the washing chamber 120 through the filter holes 111. The first opening 112 recirculates the water into the washing chamber 120, repeating the above-mentioned cat litter water circulation and washing process to clean the cat litter effectively. This cleaning process effectively reduces surface odors and prevents significant litter waste, allowing the litter to be reused after washing. The cat litter is made of PLA (polylactic acid), a biodegradable material, and is typically processed into egg-shaped particles with a diameter of 3mm-5mm. Its smooth surface facilitates cleaning and improves the comfort for cats walking on it. Because the cat litter is a completely biodegradable material with small particle size, even if a small amount is carried into the collection chamber 130 by cat feces and discharged into the sewer, it will not have an adverse impact on the environment.

[0066] In another embodiment, a water-circulating litter box is provided, including a basin body 100, a screening component 200, a water washing chamber 120, and a circulating cleaning component. The basin body 100 has a sitting / lying space 110 for placing cat litter for cats to defecate in, and the inner wall of the sitting / lying space 110 is provided with filter holes 111 for filtering out water. The screening component 200 is used to screen and discharge feces in the sitting / lying space 110, and the screening component 200 is movably disposed on the basin body 100. The water washing chamber 120 is disposed inside the basin body 100. The circulating cleaning component includes a cleaning pump 420 and a circulation pipe 410. The inlet end of the cleaning pump 420 is connected to the water washing chamber 120, and the outlet end of the cleaning pump 420 is connected to the circulation pipe 410. One end of the circulation pipe 410 is connected to the upper part or side wall of the sitting and lying space 110. The other end of the circulation pipe 410 is provided with one or more water spray holes so that the cleaning pump 420 can draw water from the water washing chamber 120 and clean the cat litter in the sitting and lying space 110 through the circulation pipe 410. The difference between this embodiment and the above embodiment is that the feeding part 300 is eliminated in this embodiment, so that the cat litter can be cleaned only in the sitting and lying space 110 without flowing into the water washing chamber 120. Of course, in order to ensure the cleaning effect of the cat litter, multiple water spray holes can be provided at the other end of the circulation pipe 410, similar to the structure of a shower head, so as to spray water to rinse and clean the cat litter in the sitting and lying space 110.

[0067] As can be seen from the above technical solution, the water circulation cleaning litter box of this application allows the cleaning pump 420 to draw water from the water washing chamber 120 and clean the litter in the sitting and lying space 110 through the circulation pipe 410. The water in the sitting and lying space 110 is filtered through the filter hole 111 and sent to the water washing chamber 120, thereby realizing water circulation to wash the litter, removing a small amount of excrement and obvious odor adhering to the surface of the litter, so that the litter can be reused, saving the cost of using the litter, making it clean and hygienic, and providing a better user experience.
