Description

Technical Field

[0001] This utility model relates to the field of pet supplies technology, and in particular to a novel cat litter box. Background Technology

[0002] With the increasing popularity of pet ownership, cats have become a favorite among many people. However, cleaning up after a cat is a constant source of trouble for owners. While cats can be trained to relieve themselves in designated spots, cleaning up their waste is still quite challenging. If waste isn't dealt with promptly, it not only affects the cat's ability to defecate but also produces an unpleasant odor, impacting people's daily lives and causing health and hygiene problems.

[0003] Currently, the main method for solving cat excretion problems is using litter boxes. However, existing litter boxes typically lack a cleaning function, causing cats to defecate directly onto the litter. This contaminated litter develops a noticeable odor, causing discomfort for both the cat and the owner. After a few days of use, the contaminated litter needs to be discarded and replaced with new litter, resulting in significant waste, environmental friendliness, and increased costs – a major pain point for owners. The inability to properly clean the litter further exacerbates the problem. Utility Model Content

[0055] 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 utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0056] Please refer to the following: Figures 1 to 13 This embodiment provides a novel cat litter box, including a shell, a cleaning chamber, a feeding section, and a circulating cleaning assembly. The shell has a holding space 121 for holding cat litter, and the cleaning chamber is disposed inside the shell for holding cat litter to be cleaned and water. The feeding section is disposed between the holding space 121 and the cleaning chamber, and is used to feed the cat litter to be cleaned from the holding space 121 into the cleaning chamber. The circulating cleaning assembly includes a circulating cleaning pump 210 and a circulating cleaning pipe 220. The inlet 211 of the circulating cleaning pump 210 is connected to the cleaning chamber, and the outlet of the circulating cleaning pump 210 is connected to the circulating cleaning pipe 220, so that the circulating cleaning pump 210 draws water and cat litter from the cleaning chamber, flows them along the circulating cleaning pipe 220 for cleaning, and then discharges them back into the holding space 121. A water-sand separation plate 140 is provided inside the holding space 121 to filter out the water in the holding space 121.

[0057] As can be seen from the above technical solution, the cat litter box of this utility model feeds the cat litter to be cleaned from the containing space 121 into the cleaning chamber through the feeding part, and the circulating cleaning pump 210 draws water and cat litter from the cleaning chamber and circulates them along the circulating cleaning pipe 220 for cleaning before discharging them back into the containing space 121. The water in the containing space 121 is filtered out by the water-sand separation plate 140, thereby realizing water circulation cleaning of the cat litter. The above-mentioned circulating water cleaning process can be repeated multiple times, resulting in a better cleaning effect, effectively reducing odors or smells, avoiding a large amount of cat litter waste, and allowing the cat litter to be reused after cleaning, providing users with a better user experience.

[0058] In some embodiments, the feeding section includes a screening plate 130, which is disposed between the accommodating space 121 and the cleaning chamber. The screening plate 130 is provided with a plurality of feeding holes 131 so that the cat litter in the accommodating space 121 is fed into the cleaning chamber through the feeding holes 131. The aperture of the feeding holes 131 is slightly larger than the particle size of the cat litter. The cat litter can basically pass through the feeding holes 131, while large pieces of cat feces cannot pass through the feeding holes 131 and are screened out. In some other embodiments, the large pieces of feces screened out by the screening plate 130 can also be manually removed.

[0059] Specifically, the housing includes a base 110, a rotating body 120, and a driving device. The rotating body 120 is rotatably mounted on the base 110. The driving device is driven to connect with the rotating body 120. The accommodating space 121 is disposed within the rotating body 120. The rotating body 120 is driven to rotate by the driving device, thereby causing the cat litter in the accommodating space 121 to slide onto the screening plate 130 and be discharged into the cleaning chamber through the discharge hole 131. The screening plate 130 is located on one side within the accommodating space 121, so that when the rotating body 120 rotates to the other side, the cat litter in the accommodating space 121 passes through the discharge hole 131 of the screening plate 130 and is discharged into the cleaning chamber for circulating cleaning.

[0060] The rotating body 120 can be spherical, hemispherical or bowl-shaped, preferably spherical. The front side of the rotating body 120 has an entrance 101 for cats to enter the accommodating space 121. The accommodating space 121 has a sitting and lying position for cats. The sitting and lying position is set on the water and sand separation plate 140. In normal conditions, a lot of cat litter is piled on the sitting and lying position for the pet cat to sleep or urinate and defecate.

[0061] In this embodiment, the circulating cleaning component is mounted on the rotating body 120. The circulating cleaning component rotates with the rotating body 120 within a predetermined angle without interference. The inlet 211 of the circulating cleaning pump 210 is connected to the cleaning chamber through a water pipe. The end of the circulating cleaning pipe 220 extends through the accommodating space 121, so that the circulating cleaning pump 210 draws water and cat litter from the cleaning chamber, circulates and cleans them along the circulating cleaning pipe 220, and then discharges them into the accommodating space 121.

[0062] Furthermore, the driving device includes a drive motor 510, a transmission gear 520, and a gear ring 530. The drive motor 510 is a 42CM06 stepper motor from Leadshine Intelligent Technology Co., Ltd., with an 80:1 worm gear reducer. The drive motor 510 is mounted on the base 110. The transmission gear 520 is connected to the output shaft of the drive motor 510. The gear ring 530 is fitted onto the rear end of the rotating body 120 and meshes with the transmission gear 520, so that the drive motor 510 drives the transmission gear 520 to rotate, and the gear ring 530 drives the rotating body to rotate. The rotating body 120 rotates on the base 110. The outer circumference of the rotating body 120 is provided with multiple annular tracks 540. The base 110 is provided with multiple sets of rollers 550, each set of rollers 550 consisting of two rollers, which are spaced apart. The outer circumference of each roller 550 is provided with annular grooves. Each annular track 540 is movably embedded in the annular groove of each set of rollers 550. Each annular track 540 is supported and rotated by two rollers 550. The base 110 and the rotating body 120 are both installed inside the outer casing 100.

[0063] In some embodiments, the litter box further includes a water filling assembly for automatically adding water to the accommodating space 121. A drive device rotates the rotating body 120, causing the water and litter in the accommodating space 121 to flow through the discharge hole 131 into the cleaning chamber. The water filling assembly includes a water filling pipe 310 and a water valve 320. A through hole 124 is provided at the rear end of the rotating body 120 along its rotation axis. The water filling pipe 310 is fixed to the base 110, and one end of the water filling pipe 310 passes through the through hole 124 into the accommodating space 121. The water pipe 310 does not contact the inner wall of the perforation 124. The other end of the water pipe 310 is used to connect to an external water source pipe. The water valve 320 is set on the water pipe 310 to control whether the water pipe 310 is flowing. The water valve 320 can be a solenoid valve, preferably the water inlet solenoid valve of Haier washing machine. The perforation 124 is opened at the center of the rear end of the rotating body 120, and one end of the water pipe 310 is inserted into the perforation 124 to enter the accommodating space 121, so that the water pipe 310 will not interfere with the rotation of the rotating body 120.

[0064] Thus, cleaning water is automatically injected into the accommodating space 121 through the water inlet pipe 310, and the cleaning water flows into the cleaning chamber through the filter holes 141 of the sand and water separation plate 140, thereby realizing the addition of water to the cleaning chamber. The accommodating space 121 is equipped with a first water level sensor 128, which can be a conventional water level sensor. The controller controls the solenoid valve to close based on the water level detection signal of the first water level sensor 128, thereby stopping the addition of water and preventing cat litter and water from overflowing during the cleaning process due to excessive water level.

[0065] The inner wall of the accommodating space 121 is equipped with an infrared sensor 129. The infrared sensor 129 is a BGX-35N diffuse reflection sensor from Boyi Precision Technology Co., Ltd. The infrared sensor 129 is used to detect whether there is a pet cat in the accommodating space 121, so as to prevent the pet cat from being injured in the accommodating space 121 during the cat litter washing process. If the infrared sensor 129 detects a pet cat in the accommodating space 121, the controller will control the cat litter box to stop the cat litter washing operation.

[0066] In this embodiment, the litter box also includes a wastewater collection chamber 111, which is located at the bottom of the containing space 121. Water in the containing space 121 is filtered out through multiple filter holes 141 of the sand-water separation plate 140 and flows into the wastewater collection chamber 111. After the litter cleaning operation is completed once, clean water can be injected into the containing space 121 to repeat the cleaning cycle multiple times, resulting in a better cleaning effect. Specifically, the wastewater collection chamber 111 is located on the base 110, so that wastewater in the containing space 121 is filtered out through the filter holes 141 and flows into the wastewater collection chamber 111 for collection. The wastewater collection chamber 111 is provided with a drain outlet 112 to discharge the wastewater in the wastewater collection chamber 111.

[0067] The top of the sewage collection chamber 111 is open, and the top wall of the sewage collection chamber 111 extends in an arc shape to fit the outer peripheral surface of the spherical rotating body 120, so that the bottom of the rotating body 120 is at least partially housed in the sewage collection chamber 111. The inner wall of the top opening of the sewage collection chamber 111 is adjacent to the outer peripheral surface of the rotating body 120. A second water level sensor 113 is installed in the sewage collection chamber 111, so that the controller controls the timely discharge of sewage in the sewage collection chamber 111 according to the water level detection signal of the second water level sensor 113, so that the sewage in the sewage collection chamber 111 will basically not overflow. Of course, in other embodiments, a brush-shaped sealing ring can be provided between the top opening of the sewage collection chamber 111 and the outer peripheral surface of the rotating body 120, which can achieve a certain sealing effect without affecting the rotation of the rotating body 120.

[0068] Furthermore, the litter box also includes a partition 150, which is disposed within the cleaning chamber to divide the cleaning chamber into a temporary storage chamber 123 and a flushing chamber 122. The temporary storage chamber 123 is located between the partition 150 and the screening plate 130. The partition 150 and the sand-water separation plate 140 are integrally formed arc-shaped plate structures. The partition 150 has several connecting holes 151, which are elongated holes. The number of connecting holes 151 can be set from 1 to 5, so that the cat litter in the accommodating space 121 can be discharged into the temporary storage chamber 123 through the discharge hole 131. The cat litter is sequentially and orderly fed into the washing chamber 122 through the connecting hole 151. The inlet 211 of the circulating cleaning pump 210 is connected to the washing chamber 122. With this configuration, a large amount of cat litter is temporarily stored in the storage chamber 123 and sequentially and gradually fed into the washing chamber 122 through the connecting hole 151 for cleaning. This avoids the cat litter flowing into the washing chamber 122 at once, which would result in poor cleaning effect due to the flow of circulating water. It also prevents the circulating cleaning pump 210 from being blocked and jammed due to the suction of a large amount of cat litter, thus further improving the safety and reliability of the product.

[0069] Specifically, the litter box is driven by a controller to rotate the rotating body 120, thereby adjusting the height of the connecting hole 151 from the water level in the cleaning chamber and thus controlling the amount of litter flowing into the suction chamber 122. This adjusts the mixing ratio of litter and water entering the circulating cleaning pump 210. The litter box can be powered by an external power supply. It can be understood that the deeper the connecting hole 151 is submerged in the cleaning water in the cleaning chamber, the more litter flows into the suction chamber 122 through the connecting hole 151. With this setting, the cleaning effect of the litter can be effectively improved by adjusting the mixing ratio of litter and water sucked by the circulating cleaning pump 210. The circulating cleaning pump 210 is a Sanyo XQB55-496 impeller-type sewage drain pump for washing machines.

[0070] The water-sand separation plate 140 has multiple filter holes 141 arranged in two groups, left and right. The left group of filter holes 141 communicates with the cleaning chamber, and the right group of filter holes 141 communicates with the wastewater collection chamber 111. When the rotating body 120 rotates to the lowest point of the left filter hole 141, the circulating cleaning pump 210 draws water and cat litter from the cleaning chamber, flows them along the circulating cleaning pipe 220 for cleaning, and then discharges them onto the water-sand separation plate 140 in the containing space 121. Then, the water in the containing space 121 flows into the cleaning chamber through the multiple filter holes 141 on the left side of the water-sand separation plate 140. After multiple cycles of suction and cleaning, the rotating body 120 is rotated until the filter hole 141 on the right is at its lowest point. At this time, the water in the accommodating space 121 flows into the sewage collection chamber 111 through multiple filter holes 141 on the right side of the sand-water separation plate 140 for collection. The cleaned cat litter is left on the sitting and lying position on the right side of the sand-water separation plate 140 for reuse next time. In other embodiments, there may be no obvious dividing line between the two sets of filter holes 141 on the left and right sides of the sand-water separation plate 140, that is, the two sets of filter holes 141 on the left and right sides may be merged into a whole set, which is also within the protection range.

[0071] In this embodiment, the inventors discovered during testing that, as Figure 11As shown, after multiple cycles of litter circulation and rinsing, the rotating body 120 is rotated by the controller until the position of the connecting hole 151 is higher than the height P of the cleaning water surface. At this time, the circulation cleaning pump 210 draws water and litter from the rinsing chamber 122 and discharges them into the receiving space 121 through the circulation cleaning pipe 220. Since the position of the connecting hole 151 is higher than the height P of the cleaning water surface, the litter discharged into the receiving space 121 will no longer flow into the rinsing chamber 122 through the connecting hole 151, thus achieving the retention of litter on the sand-water separation plate 140. The water in the receiving space 121 can still flow into the rinsing chamber 122 through the multiple filter holes 141 on the left side of the sand-water separation plate 140. After multiple cycles of rinsing by the circulation cleaning pump 210, the rinsing chamber 122 is rinsed. The cat litter in chamber 2 is almost completely replaced and discharged onto the sand-water separation plate 140 in the storage space 121. Then, the circulating cleaning pump 210 stops running and the rotating body 120 rotates clockwise, causing the water in the suction chamber 122 to flow into the storage space 121 through multiple filter holes 141 on the left side of the sand-water separation plate 140. Then, it flows into the sewage collection chamber 111 through multiple filter holes 141 on the right side of the sand-water separation plate 140, the interval space 126, and the through-hole 127, thereby completely draining the water in the suction chamber 122. There is basically no cat litter residue in the suction chamber 122, and even if some cat litter remains in the suction chamber 122, it can be extracted into the storage space 121 during the next cat litter cleaning process.

[0072] Furthermore, a space 126 is provided between the right half of the water-sand separation plate 140 and the inner wall of the rotating body 120. A baffle 142 is provided between the space 126 and the suction chamber 122 of the cleaning chamber. A through-hole 127 is provided at the bottom of the space 126 so that the multiple filter holes 141 on the right side of the water-sand separation plate 140 can be connected to the sewage collection chamber 111 through the through-hole 127. The water filtered by the multiple filter holes 141 on the right side of the water-sand separation plate 140 flows into the sewage collection chamber 111 for collection through the space 126 and the through-hole 127.

[0073] In some embodiments, the litter box further includes a drying assembly, which includes a drying channel 410, a heater 430, and a fan unit 420. The air blown out by the fan unit 420 is heated by the heater 430 and then blown into the receiving space 121 through the drying channel 410 and the filter hole 141 to dry the litter in the receiving space 121. In the litter drying state, one end of the drying channel 410 is correspondingly arranged with the through opening 127, and the fan unit 420 and the heater 430 are installed at the other end of the drying channel 410. The air blown out by the fan unit 420 is heated by the heater 430 and then blown into the receiving space 121 through the drying channel 410, the through opening 127, and the filter hole 141 to dry the litter in the receiving space 121.

[0074] One end of the drying channel 410 extends into the wastewater collection chamber 111, and the other end extends to the outside of the base 110. The other end of the drying channel 410 extends upward, and the fan unit 420 and heater 430 are installed at the top of the other end of the drying channel 410. One end of the drying channel 410 is at a certain height in the wastewater collection chamber 111. Due to the large inner width of the wastewater collection chamber 111, the water level of the wastewater after cleaning the cat litter is low and will not exceed the height of one end of the drying channel 410. Furthermore, the second water level sensor 113 in the wastewater collection chamber 111 will detect the water level to achieve timely drainage. The water in the wastewater collection chamber 111 will not flow into the drying channel 410. Even if a small amount of water seeps into the drying channel 410 through one end, it will not affect the normal operation of the higher-positioned fan unit 420 and heater 430.

[0075] In some embodiments, a discharge port 125 is provided on one side of the rotating body 120 so that when the rotating body 120 rotates, the cat's excrement on the receiving space 121 is separated from the cat litter by the screening plate 130 and discharged into the sewage collection chamber 111 through the discharge port 125. The screening plate 130 is located on the left side of the water-sand separation plate 140, and multiple feeding holes 131 are located on the right half of the screening plate 130. The left half of the screening plate 130 is a sand baffle. The discharge port 125 is located on the left side of the screening plate 130 so that multiple cat litter passes through the feeding holes 131 into the temporary storage chamber 123 to wait for washing during the cat litter screening process. Large pieces of cat excrement or feces are screened out by the screening plate 130 and roll into the sewage collection chamber 111 for collection along the screening plate 130 and the discharge port 125. Due to the blocking effect of the sand baffle, the cat litter in the temporary storage chamber 123 will not roll into the sewage collection chamber 111, thereby improving the reliability and practicality of the product.

[0076] The sewage collection chamber 111 is equipped with a pulverizer 610 at its discharge port 112. The pulverizer 610 uses a common 4052 DC motor for crushing feces, which crushes large pieces of cat excrement. The output port of the pulverizer 610 is connected to an external pipe and a sewage pump 620. The sewage pump 620 is a Sanyo XQB55-496 impeller-type sewage pump. The crushed feces dissolve in the sewage and are discharged by the suction of the sewage pump 620. This configuration allows for the centralized collection and discharge of large pieces of cat excrement and sewage in the sewage collection chamber 111, making it convenient to use.

[0077] In some embodiments, a magnetic flux sensor 560 is provided on the base 110, and a magnet is provided on the rotating body 120. The controller controls the drive device to drive the rotating body 120 to rotate and reset to the initial state based on the signal detected by the magnetic flux sensor 560, so as to prepare for the next cycle cleaning process. The controller also controls the drive device to drive the rotating body 120 to rotate to a preset rotation angle corresponding to the cat litter screening state, feces discharge state, cat litter cycle cleaning state, cat litter draining state, and cat litter drying state. The cat litter box is programmed with preset rotation angles corresponding to each state before leaving the factory, so that the rotating body 120 can switch to the corresponding working state by rotating to the corresponding preset rotation angle. The degree of automation is high, it is easy to use, and basically no manual assistance is required.

[0078] Please refer to the following when using it. Figure 7 In its initial daily state, the litter box contains a large amount of litter piled on the litter separator 140 for the cat to use for urination and defecation. After the cat has finished and left, the litter box cleaning program is activated, and the rotating body 120 rotates counterclockwise. Figure 8 As shown, contaminated cat litter and feces in the containing space are sifted through the screening plate 130 under the action of gravity. The cat litter passes through the discharge hole 131 of the screening plate 130 and enters the temporary storage chamber 123, while the cat feces are screened out. As the rotating body 120 continues to rotate, as... Figure 9 As shown, cat feces, under the influence of gravity, roll through the discharge port 125 into the sewage collection chamber 111, and then the rotating body 120 rotates, as... Figure 10 As shown, the water valve 320 of the water inlet pipe 310 is opened, and cleaning water is injected into the accommodating space 121. The cleaning water is used to rinse part of the route that the feces have taken, reducing residue. At the same time, the wastewater after rinsing also enters the wastewater collection chamber 111, where the cat's feces are soaked and softened, and can be crushed and discharged by the pulverizer 610.

[0079] During the litter circulation cleaning process, the rotating body 120 rotates clockwise until the height of the inlet 211 of the circulation cleaning pump 210 is at its lowest point. The first water level sensor 128 detects the water level in the cleaning chamber and the storage space 121. After reaching an appropriate water level, the controller stops the water supply, and the water level submerges the inlet 211 of the circulation cleaning pump 210. The rotating body 120 rotates counterclockwise, causing a large amount of litter in the storage space 121 to enter the temporary storage chamber 123. The large amount of litter flows sequentially through the connecting hole 151 into the suction chamber 122. The controller then controls the circulation cleaning pump 210 to open, so that the water and litter in the suction chamber 122 are drawn out by the circulation cleaning pump 210, flow along the circulation cleaning pipe 220 for cleaning, and then discharged back into the storage space 121. The litter box uses a controller to drive a rotating body 120, which in turn adjusts the water level in the cleaning chamber from the connecting hole 151. This controls the amount of litter flowing into the suction chamber 122, thus adjusting the mixing ratio of litter and water entering the circulating cleaning pump 210. The controller can set the mixing ratio based on the litter particle diameter, the power of the circulating cleaning pump 210, and the water flow rate. The controller uses an STM32 MCU as the main controller. During the circulating water pump 210's pumping process, the impeller of the circulating cleaning pump 210 rubs against the litter, while the water flow in the circulating cleaning pipe 220 also impacts, rubs, and vibrates the litter, quickly cleaning the contaminated litter. The cleaning effect is excellent, and because it uses a circulating system, water consumption is very low, making it environmentally friendly and energy-efficient.

[0080] like Figure 10As shown, after multiple litter circulation and rinsing cycles, the controller controls the rotating body 120 to rotate until the position of the connecting hole 151 is higher than the height P of the cleaning water surface. At this time, the circulation cleaning pump 210 draws water and litter from the rinsing chamber 122 and discharges them into the receiving space 121 through the circulation cleaning pipe 220. Since the position of the connecting hole 151 is higher than the height P of the cleaning water surface, the litter discharged into the receiving space 121 will no longer flow into the rinsing chamber 122 through the connecting hole 151, thus achieving the effect of the litter remaining on the water-sand separation plate 140, while the water in the receiving space 121 can still flow through the multiple filter holes 141 on the left side of the water-sand separation plate 140. The litter enters the suction chamber 122 and is repeatedly pumped by the circulating cleaning pump 210, which can replace and discharge almost all the litter in the suction chamber 122 onto the sand-water separation plate 140 in the holding space 121. Then, the circulating cleaning pump 210 stops running and the rotating body 120 rotates clockwise, causing the water in the suction chamber 122 to flow into the holding space 121 through multiple filter holes 141 on the left side of the sand-water separation plate 140. Then, it flows into the sewage collection chamber 111 through multiple filter holes 141 on the right side of the sand-water separation plate 140, the interval space 126, and the through-hole 127, thereby achieving the complete discharge of the water in the suction chamber 122.

[0081] Furthermore, the controller controls the rotating body 120 to rotate to the litter draining state, such as... Figure 12 As shown, the cleaned cat litter is drained through the filter hole 141 on the right side of the water-litter separation plate 140. Excess water in the containing space 121 is discharged into the wastewater collection chamber 111 through the through-hole 127 for collection. After draining, the controller controls the drive device to rotate the rotating body 120 to the cat litter drying state. At this time, the through-hole 127 at the bottom of the rotating body 120 is aligned with the drying air vent of the drying channel 410, so that the air blown out by the fan unit 420 is heated by the heater 430 and then blown into the containing space 121 through the drying channel 410, the through-hole 127 and the filter hole 141 to dry the cat litter in the containing space 121. After the cat litter is dried, the litter box stops working and is ready for the next use.

[0082] In other embodiments, this embodiment provides a novel litter box, including a shell, a cleaning chamber, and a circulating cleaning assembly. The shell has a receiving space 121 for holding cat litter, and the cleaning chamber is disposed within the shell. The circulating cleaning assembly includes a circulating cleaning pump 210 and a circulating cleaning pipe 220. The inlet 211 of the circulating cleaning pump 210 is connected to the cleaning chamber, and the outlet of the circulating cleaning pump 210 is connected to the circulating cleaning pipe 220, so that water in the cleaning chamber is drawn by the circulating cleaning pump 210, flows along the circulating cleaning pipe 220, and is discharged into the receiving space 121 to rinse the cat litter. A water-sand separation plate 1 is provided within the receiving space 121. 40. Water in the holding space 121 is filtered out by the sand-water separation plate 140 and then flows back into the cleaning chamber. The only difference from the above embodiment is that the cat litter is always in the holding space 121 and does not enter the cleaning chamber. The circulating cleaning pump 210 draws water from the cleaning chamber, flows along the circulating cleaning pipe 220 and discharges it into the holding space 121 to rinse the cat litter. Of course, in this embodiment, large pieces of cat excrement can be manually removed first, and then the circulating water flow can be started to rinse the cat litter in the holding space 121, so that small particles of feces dissolve in the water and are discharged with the water flow, which can also achieve the effect of circulating water to clean the cat litter.

[0083] As can be seen from the above technical solution, in this embodiment, the litter box uses a circulating cleaning pump 210 to draw water from the cleaning chamber, which circulates along the circulating cleaning pipe 220 and is then discharged into the containing space 121 to rinse the litter. The water in the containing space 121 is filtered out by the water-sand separation plate 140, thus achieving the cleaning of the litter. This cleaning process can be repeated multiple times, resulting in good cleaning effect, effectively reducing odors and avoiding significant litter waste. The litter can be reused after cleaning. The litter is made of PLA (polylactic acid), a biodegradable material, and can typically be processed into egg-shaped particles with a diameter of 3mm-5mm. Its smooth surface facilitates cleaning and improves the feel under the cat's paws. Because it is a completely biodegradable material with small particle size, even if a small amount is carried into the wastewater tank by the cat's feces and discharged into the sewer, it will not have an adverse impact on the environment.
