[0056] In some embodiments, the discharging part comprises a screening plate 130 arranged between the containing space 121 and the cleaning cavity. The screening plate 130 is provided with a plurality of discharging holes 131, so that cat litter in the containing space 121 is discharged into the cleaning cavity through the discharging holes 131. The diameter of the discharging holes 131 is slightly larger than the particle size of the cat litter, and the cat litter can basically pass through the discharging holes 131, while large feces of the cat cannot pass through the discharging holes 131 and are screened out. In other embodiments, the large feces screened out by the screening plate 130 can also be manually cleaned out.

[0057] Specifically, the shell comprises a base 110, a rotating body 120 rotatably mounted on the base 110, and a driving device drivingly connected with the rotating body 120. A containing space 121 is arranged in the rotating body 120. The driving device drives the rotating body 120 to rotate, so that the cat litter in the containing space 121 slides onto the screening plate 130 and is discharged into the cleaning cavity through the discharge hole 131. The screening plate 130 is located on one side of the containing space 121, so that when the rotating body 120 rotates towards the other side, the cat litter in the containing space 121 is discharged into the cleaning cavity through the discharge hole 131 of the screening plate 130 for circulating flow cleaning.

[0058] In the embodiment, the rotating body 120 can adopt a spherical, hemispherical or bowl structure, preferably a spherical structure. A cat entrance 101 is formed on the front side of the rotating body 120 for the cat to enter the containing space 121. The containing space 121 has a sitting and lying position for the cat to sit and lie. The sitting and lying position is arranged on the water-sand separation plate 140. In the daily state, a large amount of cat litter is piled on the sitting and lying position for the pet cat to sleep or urinate on the sitting and lying position.

[0059] In the embodiment, the circulating cleaning assembly is arranged on the rotating body 120. The circulating cleaning assembly rotates within a predetermined angle with the rotating body 120 without interference. The inlet 211 of the circulating cleaning pump 210 is communicated with the cleaning cavity through a water pipe. The end of the circulating cleaning pipeline 220 extends into the containing space 121, so that the circulating cleaning pump 210 can extract the water and cat litter in the cleaning cavity to flow along the circulating cleaning pipeline 220 for circulating flow cleaning and then be discharged into the containing space 121.

[0060] Further, the driving device comprises a driving motor 510, a transmission gear 520 and a gear ring 530. The driving motor 510 adopts a 42CM06 stepper motor of Raysee Intelligence Company, wherein the reduction box is an 80:1 worm reduction box. The driving motor 510 is arranged on the base 110. The transmission gear 520 is drivingly connected with the output shaft of the driving motor 510. The gear ring 530 is sleeved on the rear end of the rotating body 120 and is in meshing connection with the transmission gear 520, so that the driving motor 510 drives the transmission gear 520 to rotate and drives the rotating body 120 to rotate on the base 110 through the gear ring 530. The outer periphery of the rotating body 120 is spaced apart to form a plurality of annular tracks 540. A plurality of groups of rollers 550 are arranged on the base 110. Each group of rollers 550 has two rollers 550 which are spaced apart. The outer periphery of each roller 550 is provided with an annular groove. Each annular track 540 is movably embedded in the annular groove of each group of rollers 550. Each annular track 540 is rotatably supported and installed by the two rollers 550. The base 110 and the rotating body 120 are both arranged in the shell 100.

[0061] In some embodiments, the cat litter box further comprises a water adding assembly for automatically adding water into the accommodating space 121 through the water adding assembly, and driving the rotation body 120 to rotate through the driving device so that the water and cat litter in the accommodating space 121 are discharged into the cleaning cavity through the discharge hole 131, the water adding assembly comprises a water adding pipe 310 and a water valve 320, the rear end of the rotation body 120 is provided with a through hole 124 along the rotation axis direction, the water adding pipe 310 is fixed on the base 110, one end of the water adding pipe 310 is arranged in the accommodating space 121 through the through hole 124, the water adding pipe 310 does not contact the inner wall of the through hole 124, the other end of the water adding pipe 310 is used for connecting with a water source pipeline, and the water valve 320 is arranged on the water adding pipe 310 to control whether the water adding pipe 310 is communicated through the water valve 320. The water valve 320 can adopt an electromagnetic valve, preferably an inlet electromagnetic valve of a Haier washing machine. The through hole 124 is arranged at the center of the rear end of the rotation body 120, and one end of the water adding pipe 310 is arranged in the through hole 124 to enter the accommodating space 121, so that the water adding pipe 310 does not interfere with the rotation of the rotation body 120.

[0062] In this way, the cleaning water is automatically injected into the accommodating space 121 through the water adding pipe 310, and the cleaning water flows into the cleaning cavity through the filter hole 141 of the water and sand separation plate 140, so as to realize water adding into the cleaning cavity. The first water level sensor 128 is arranged in the accommodating space 121, and the first water level sensor 128 can adopt a conventional water level sensor, so as to control the electromagnetic valve to be closed and the water adding to be stopped through the controller according to the water level detection signal of the first water level sensor 128, so as to avoid the overflow of cat litter and water in the cleaning process due to the too high water level.

[0063] The inner wall of the accommodating space 121 is provided with an infrared sensor 129, the infrared sensor 129 adopts a BGX-35N diffuse reflection sensor of Bo Yijingke Company, and 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 damaged in the cat litter cleaning process. If the infrared sensor 129 detects that the pet cat is in the accommodating space 121, the cat litter box is stopped for cat litter cleaning work by the controller.

[0064] In the embodiment, the cat litter box further comprises a sewage collection bin 111 arranged at the bottom of the accommodation space 121 to filter out the water in the accommodation space 121 through the plurality of filter holes 141 of the water-sand separation plate 140 and flow into the sewage collection bin 111, and clean water can be injected into the accommodation space 121 again after one cat litter cleaning operation to repeat the cleaning of the cat litter multiple times, so that the cleaning effect is better. Specifically, the sewage collection bin 111 is arranged on the base 110 to filter out the sewage in the accommodation space 121 through the filter holes 141 and flow into the sewage collection bin 111 for collection, and the sewage collection bin 111 is provided with a sewage outlet 112 to discharge the sewage in the sewage collection bin 111 through the sewage outlet 112.

[0065] The top of the sewage collection bin 111 is arranged in an open manner, and the top wall of the sewage collection bin 111 extends in an arc shape to adapt to the outer circumferential surface of the spherical rotating body 120, so that the bottom of the rotating body 120 is at least partially accommodated in the sewage collection bin 111. The top open inner wall of the sewage collection bin 111 is arranged adjacent to the outer circumference of the rotating body 120, and a second water level sensor 113 is arranged in the sewage collection bin 111 to control the timely discharge of the sewage in the sewage collection bin 111 according to the water level detection signal of the second water level sensor 113 through the controller, so that the sewage in the sewage collection bin 111 basically will not overflow. Of course, in other embodiments, a brush-shaped sealing ring can be arranged between the top open of the sewage collection bin 111 and the outer circumference of the rotating body 120 to achieve a certain sealing effect without affecting the rotation of the rotating body 120.

[0066] Further, the cat litter box further comprises a partition plate 150 arranged in the cleaning cavity to divide the cleaning cavity into a temporary storage cavity 123 and a pumping and washing cavity 122 through the partition plate 150. The temporary storage cavity 123 is located between the partition plate 150 and the screening plate 130, and the partition plate 150 and the water-sand separation plate 140 are an arc-shaped plate structure formed integrally. A plurality of communication holes 151 are formed in the partition plate 150, and the communication holes 151 are long strip-shaped holes. The number of communication holes 151 can be 1-5. The cat litter in the accommodation space 121 is discharged to the temporary storage cavity 123 through the discharge hole 131 and then sequentially and orderly discharged to the pumping and washing cavity 122 through the communication holes 151. The inlet 211 of the circulating cleaning pump 210 is communicated with the pumping and washing cavity 122. In this way, a large amount of cat litter is temporarily stored in the temporary storage cavity 123 and sequentially and orderly discharged to the pumping and washing cavity 122 for cleaning through the communication holes 151, which avoids the poor cleaning effect of the cat litter caused by the large amount of cat litter flowing with the circulating water flow when the large amount of cat litter is discharged into the pumping and washing cavity 122 at the same time, and prevents the circulating cleaning pump 210 from being blocked and jammed caused by the large amount of cat litter being sucked by the circulating cleaning pump 210, thereby further improving the safety and reliability of the product.

[0067] Specifically, the cat litter basin drives the rotating body 120 to rotate by the driving device controlled by the controller, so as to adjust the distance between the communication hole 151 and the liquid level of the water in the cleaning cavity, and then control the entering amount of the cat litter into the pumping and cleaning cavity 122, so as to adjust the mixing ratio of the cat litter and water entering the circulating cleaning pump 210. The cat litter basin can be powered by externally inserting a power supply. It can be understood that the deeper the communication hole 151 is immersed in the cleaning water in the cleaning cavity, the more cat litter enters the pumping and cleaning cavity 122 through the communication hole 151. In this way, the mixing ratio of the cat litter and water sucked by the circulating cleaning pump 210 can be adjusted, so as to effectively improve the cleaning effect of the cat litter. The circulating cleaning pump 210 adopts a Sanyo washing machine XQB55-496 impeller type sewage drainage pump.

[0068] Among them, the plurality of filter holes 141 on the water and sand separation plate 140 are arranged as two groups on the left and right. The plurality of filter holes 141 on the left are in communication with the cleaning cavity, and the plurality of filter holes 141 on the right are in communication with the sewage collection bin 111. When the rotating body 120 is rotated to the leftmost point of the filter hole 141, the water and cat litter in the cleaning cavity are extracted by the circulating cleaning pump 210, and then flow along the circulating cleaning pipeline 220 for cleaning and then discharged into the water and sand separation plate 140 in the containing space 121. Then, the water in the containing space 121 flows into the cleaning cavity through the plurality of filter holes 141 on the left of the water and sand separation plate 140. After multiple cycles of suction and flow cleaning, the rotating body 120 is rotated to the rightmost point of the filter hole 141. At this time, the water in the containing space 121 is filtered and flows into the sewage collection bin 111 through the plurality of filter holes 141 on the right of the water and sand separation plate 140 for collection. The cat litter after cleaning is left on the sitting and lying position on the right of the water and sand separation plate 140 for repeated use next time. In other embodiments, of course, there is no obvious boundary between the two groups of filter holes 141 on the water and sand separation plate 140, that is, the two groups of filter holes 141 are integrated into a whole group, which is also within the protection scope.

[0069] In the present embodiment, the applicant found in the process of testing that, as shown in FIG. 11, after the cat litter is repeatedly cleaned by the circulation, the rotating body 120 is controlled by the controller to rotate to a position of the communication hole 151 higher than the height P of the cleaning water level, at which time the circulation cleaning pump 210 sucks the water and cat litter in the cleaning cavity 122 and discharges them into the containing space 121 through the circulation cleaning pipeline 220. Since the position of the communication hole 151 is higher than the height P of the cleaning water level at this time, the cat litter discharged into the containing space 121 will not flow into the cleaning cavity 122 through the communication hole 151, so as to achieve the cat litter retention on the water-sand separation plate 140, while the water in the containing space 121 can still flow into the cleaning cavity 122 through the plurality of filter holes 141 on the left side of the water-sand separation plate 140. After the circulation cleaning pump 210 is repeatedly circulated and sucked, the cat litter in the cleaning cavity 122 can be basically replaced and discharged onto the water-sand separation plate 140 in the containing space 121. Then, the circulation cleaning pump 210 stops running, the rotating body 120 is rotated in the clockwise direction, and the water in the cleaning cavity 122 flows into the containing space 121 through the plurality of filter holes 141 on the left side of the water-sand separation plate 140, and then sequentially flows into the sewage collection bin 111 through the plurality of filter holes 141 on the right side of the water-sand separation plate 140, the interval space 126, and the through hole 127, so as to achieve the complete discharge of the water in the cleaning cavity 122. Among them, there is basically no cat litter remaining in the cleaning cavity 122, and even if there are some cat litter remaining in the cleaning cavity 122, it can be sucked out into the containing space 121 in the next cat litter cleaning process.

[0070] Further, the interval space 126 is arranged between the right half of the water-sand separation plate 140 and the inner wall of the rotating body 120, the baffle 142 is arranged between the interval space 126 and the cleaning cavity 122 of the cleaning cavity 122, and the through hole 127 is arranged at the bottom of the interval space 126, so as to make the plurality of filter holes 141 on the right side of the water-sand separation plate 140 communicate with the sewage collection bin 111 through the through hole 127.
