Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of pet equipment, and particularly relates to an intelligent cat litter machine. BACKGROUND

[0002] With the continuous improvement of living standards, more and more families choose pets as daily companions, especially in economically developed cities, the proportion of people feeding pets is higher. Among them, since cats will habitually use sand to bury excrement after defecation, it is a clean behavior, and cats are pure and lovely, therefore, more and more people like to raise pet cats.

[0003] People who raise pet cats usually use a cat litter box for pet cats to defecate in, which is convenient for pet cats to bury excrement after defecation, so as to keep the living environment clean and tidy. After pet cats defecate several times in the ordinary cat litter box, the cat litter in the cat litter box must be cleaned or replaced in time, otherwise, the accumulation of buried feces in the cat litter will affect the pet cats to continue defecating. Therefore, the intelligent cat litter machine emerges as the times require. After the pet cats defecate each time, the intelligent cat litter machine can rake and filter the buried feces in the cat litter, so as to avoid the accumulation of buried feces in the cat litter. In this way, it not only facilitates the pet cats to continue defecating, but also reduces the frequency of cleaning or replacing the cat litter.

[0004] However, the cat litter rake of the current intelligent cat litter machine will have feces sticking to the rake teeth during the process of cleaning the cat litter. If the feces sticking to the cat litter rake is not cleaned in time, the feces will block the gap between the rake teeth, and then cause the resistance to increase in the subsequent process of raking and filtering the cat litter by the cat litter rake, resulting in the decline of the raking and filtering capacity of the cat litter rake. Moreover, the blocked gap between the rake teeth will rake out the cat litter together with the feces, causing the waste of cat litter. CONTENT OF THE UTILITY MODEL

[0052] As Figures 1 to 12As shown, the intelligent cat litter machine provided by the embodiments of the present application comprises a litter basin assembly 10, a litter rake mechanism 20 and a cleaning device 30. The litter basin assembly 10 comprises two opposite frame plates 13, which provide support for the entire intelligent cat litter machine and enable it to be stably placed on the ground. In addition, a first containing space 11 for containing cat litter and a second containing space 12 for collecting cat feces separated from the cat litter by the cat litter rake are arranged between the two frame plates 13. The cat litter is a sanitary product designed for pet cats to provide a place for defecation and is usually made of mineral substances, plant fibers, silica gel and the like. Therefore, purchasing cat litter is an important part of the cost of raising a cat. The cat litter rake 21 and two supports 22 are arranged in the litter basin assembly 10. The two supports 22 are respectively slidably arranged on the two frame plates 13, and the support 22 is provided with a triggering part 221. At least one support 22 is provided with a power device 23. The cat litter rake 21 comprises a plurality of rake teeth 212 for raking cat litter. The cleaning device 30 is arranged on the litter basin assembly 10. Specifically, the cleaning device 30 comprises a power structure 31 and a cleaning rake 32 connected with the power structure 31. The cleaning rake 32 comprises a plurality of cleaning teeth 322 extending towards the second containing space 12. During the process of raking cat litter by the cat litter rake 21, i.e., the cat litter rake 21 moves in the direction indicated by the arrow S1 in FIG. 1 and rakes cat litter, when the power structure 31 is triggered by the triggering part 221 to drive the cleaning rake 32 to rotate in the first direction W, the plurality of cleaning teeth 322 are in the first working position to avoid the plurality of rake teeth 212; when the power structure 31 is disengaged from the triggering part 221 to drive the first horizontal rod 321 to rotate in the reverse direction, the plurality of cleaning teeth 322 are in the second working position to cross the plurality of rake teeth 212 alternately, as shown in FIG. 2. Figure 3 As shown in FIG. 3, during the process of the plurality of rake teeth 212 retreating to the initial position, i.e., the cat litter rake 21 moves in the direction indicated by the arrow S2 in FIG. 2, the feces adhering to the plurality of rake teeth 212 are scraped off and collected in the second containing space 12. Figure 6 As shown in FIG. 4, the plurality of cleaning teeth 322 are in the first working position to avoid the plurality of rake teeth 212. Figure 7 As shown in FIG. 5, the plurality of cleaning teeth 322 are in the second working position to cross the plurality of rake teeth 212 alternately. Figure 6 As shown in FIG. 6, during the process of the plurality of rake teeth 212 retreating to the initial position, i.e., the cat litter rake 21 moves in the direction indicated by the arrow S2 in FIG. 2, the feces adhering to the plurality of rake teeth 212 are scraped off and collected in the second containing space 12.

[0053] In the smart litter box provided by the embodiments of the present application, when the pet cat finishes defecating in the litter each time, the litter rake 21 is driven by the power device 23 to move on the shelf plate 13 in the direction S1, and the defecation block buried in the litter is separated by the rake, and the power device 23 drives the litter rake 21 to transfer and dump the defecation block separated by the rake into the second containing space 12, so as to collect the defecation block to facilitate subsequent cleaning of the defecation block. In the cleaning device 30 of the smart litter box, the second working position is the initial working position of the cleaning teeth 322 of the cleaning rake 32, that is, the cleaning teeth 322 are located at the second working position before the litter rake mechanism 20 moves to the second containing space 12. When the litter rake mechanism 20 moves to the contact part 221 to contact and trigger the power structure 31 of the cleaning device 30, the power structure 31 is started and drives the cleaning rake 32 to rotate in the first direction W, so that the cleaning teeth 322 are changed from the second working position to the first working position, so that the cleaning teeth 322 can avoid the rake teeth 212, and then the defecation block on the rake teeth 212 is smoothly dumped into the second containing space 12, as shown in Figure 4 、 Figure 5 and Figure 8 . Then, the litter rake mechanism 20 moves back to make the contact part 221 disengage the power structure 31, and the power structure 31 drives the cleaning rake 32 to rotate reversely (rotate in the direction opposite to the first direction W), so that the cleaning teeth 322 are returned from the first working position to the second working position, at this time, the plurality of cleaning teeth 322 and the plurality of rake teeth 212 are alternately crossed in sequence, as shown in Figure 6 and Figure 7 . In this way, in the process of the rake teeth 212 returning to the initial position, the cleaning teeth 322 scrape the defecation block adhered to the rake teeth 212 and collect it in the second containing space 12, so as to reduce the defecation block adhered to the rake teeth 212, reduce the possibility of the gap of the rake teeth 212 being blocked by the defecation block, so that the litter rake 21 can continuously maintain a high rake separation capacity, and reduce the waste caused by the litter adhered to the rake teeth 212.

[0054] Specifically, the sand rake mechanism 20 of the intelligent cat litter machine further comprises a control device (not shown), which is installed on the bracket 22 and electrically connected with the power device 23 to realize intelligent control. When the pet cat finishes defecating in the cat litter each time, the control device controls the power device 23 to start, and then the power device 23 drives the cat litter rake 21 to move along the direction S1 to separate the buried fecal pieces in the cat litter. In addition, the cat litter rake 21 further comprises a second cross rod 211, a plurality of rake teeth 212 are arranged at intervals on the second cross rod 211, and both ends of the second cross rod 211 are rotatably installed on the two brackets 22. The power device 23 is drivingly connected with the second cross rod 211 to drive the cat litter rake 21. Further, the cleaning device 30 is located between the first containing space 11 and the second containing space 12, and the cleaning rake 32 further comprises a first cross rod 321, a plurality of cleaning teeth 322 are arranged at intervals on the first cross rod 321, and the power structure 31 is connected with the first cross rod 321.

[0055] In the intelligent cat litter machine of the embodiment of the present application, as shown in Figures 1 to 10 The sand basin assembly 10 further comprises a cat litter basin 14 which is detachably arranged between the two shelf plates 13 to form the first containing space 11. That is, the cat litter basin 14 can be detached and taken out of the two shelf plates 13 by the user, so as to facilitate the user to deeply clean or replace new cat litter in the cat litter basin 14, prevent the cat litter from producing odor due to long-term use, and keep the environment clean. In addition, the cleaning rake 32 of the cleaning device 30 is fixedly installed on the side wall of the cat litter basin 14 facing the second containing space 12. In this way, when the cat litter basin 14 is detached and taken out of the two shelf plates 13 by the user, the cleaning rake 32 is also taken out together. Since the cleaning teeth 322 of the cleaning rake 32 are inevitably stuck with residual cat feces when scraping the cat feces adhered to the rake teeth 212, the cleaning rake 32 is taken out together with the cat litter basin 14, so that the user can clean the cleaning rake 32 to clean the residual cat feces adhered to the cleaning teeth 322.

[0056] As shown in Figures 10 to 12 The cleaning device 30 further comprises two connecting seats 33 which are fixedly connected to the two sides of the cat litter basin 14. In addition, both ends of the first cross rod 321 are rotatably installed on the two connecting seats 33, so that the first cross rod 321 can be smoothly reciprocated between the first working position and the second working position. In the cleaning device 30 of the intelligent cat litter machine, as shown in Figures 10 to 12As shown, the power structure 31 comprises a swing arm 311 and an elastic member 312, at least one end of the first cross bar 321 is fixedly connected with the swing arm 311, specifically, the swing arm 311 is locked on the end of the first cross bar 321 through a fastening screw 314, the swing arm 311 is located between the shelf plate 13 and the litter pan 14 to contact or disengage with the triggering part 221, the elastic member 312 is arranged between the swing arm 311 and the litter pan 14, the elastic member 312 provides an elastic force to reset the cleaning teeth 322 from the first working position to the second working position. When the sand rake mechanism 20 moves to the triggering part 221 to contact and trigger the swing arm 311 along the S1 direction, the sand rake mechanism 20 continues to move to overcome the elastic force of the elastic member 312, the swing arm 311 drives the first cross bar 321 to rotate in the first direction W, so that the cleaning teeth 322 of the cleaning rake 32 rotate from the initial working position (i.e. the second working position) to the first working position, so that the cleaning teeth 322 can avoid the rake teeth 212, and then smoothly dump the clumps on the rake teeth 212 into the second containing space 12. Then, the sand rake mechanism 20 moves back along the S2 direction to make the triggering part 221 disengage from the swing arm 311, the swing arm 311 drives the first cross bar 321 to reversely rotate (rotate in the direction opposite to the first direction W) under the action of the elastic force of the elastic member 312, so that the cleaning teeth 322 are restored from the first working position to the second working position, at this time, the plurality of cleaning teeth 322 and the plurality of rake teeth 212 are alternately crossed, as shown in Figure 6 and Figure 7 As shown. In this way, during the process of the rake teeth 212 returning to the initial position, the cleaning teeth 322 scrape the clumps adhered on the rake teeth 212 and collect them in the second containing space 12, thereby reducing the clumps adhered on the rake teeth 212, reducing the possibility of the clumps blocking the gap of the rake teeth 212, enabling the litter rake 21 to continuously maintain a high raking capacity, and reducing the waste caused by the litter being taken out by the clumps adhered on the rake teeth 212.

[0057] In the intelligent litter machine of the embodiment of the present application, as shown in Figures 2 to 7 , Figure 9 The litter pan assembly 10 further comprises a clump pan 15, the clump pan 15 is detachably arranged between the two shelf plates 13 to form the second containing space 12. In this way, the clump pan 15 can be detached and taken out from the two shelf plates 13 by the user, thereby facilitating the user to handle the clumps collected in the clump pan 15, preventing the clumps from accumulating too much and for too long to produce odor, and keeping the environment clean.

[0058] In the smart litter box of some embodiments of the present application, the cleaning device 30 further comprises two connecting seats 33, which are respectively fixedly connected to the two sides of the litter basin 14. Moreover, the two ends of the first horizontal rod 321 are respectively rotatably installed on the two connecting seats 33, so that the first horizontal rod 321 can be smoothly reciprocated between the first working position and the second working position. In the cleaning device 30 of the smart litter box, as shown in Figures 15 to 16 the power structure 31 comprises a swing arm 311, a resilient member 312 and a connecting member 313, the swing arm 311 is rotatably connected to the shelf plate 13, the swing arm 311 is located between the shelf plate 13 and the litter basin 14 to contact or disengage with the triggering part 221, the connecting member 313 is fixedly connected to the swing arm 311, the resilient member 312 is arranged between the swing arm 311 and the shelf plate 13, and the connecting member 313 is connected with the end of the first horizontal rod 321 when the litter basin 14 is placed between the two shelf plates 13, so that the connecting member 313 and the first horizontal rod 321 are synchronously rotated with the swing arm 311, and the resilient member 312 provides a resilient force to reset the cleaning teeth 322 from the first working position to the second working position. When the sand rake mechanism 20 moves to contact and trigger the swing arm 311, the sand rake mechanism 20 continues to move to overcome the resilient force of the resilient member 312, the swing arm 311 drives the first horizontal rod 321 to rotate in the first direction W, so that the cleaning teeth 322 of the cleaning rake 32 are rotated from the initial working position (i.e. the second working position) to the first working position, so that the cleaning teeth 322 can avoid the rake teeth 212, and then the clumps on the rake teeth 212 are smoothly poured into the second containing space 12. Then, the sand rake mechanism 20 moves back to make the triggering part 221 disengage from the swing arm 311, the swing arm 311 drives the first horizontal rod 321 to reversely rotate (rotate in the direction opposite to the first direction W) under the action of the resilient force of the resilient member 312, so that the cleaning teeth 322 are restored from the first working position to the second working position, at this time, the plurality of cleaning teeth 322 and the plurality of rake teeth 212 are alternately crossed. In this way, in the process of the rake teeth 212 returning to the initial position, the clumps adhering to the rake teeth 212 are scraped off and collected in the second containing space 12, thereby reducing the clumps adhering to the rake teeth 212, reducing the possibility of the gap of the rake teeth 212 being blocked by the clumps, enabling the litter rake 21 to continuously maintain a high raking capacity, and reducing the waste caused by the litter being taken out by the clumps adhering to the rake teeth 212.

[0059] In the smart litter box of some other embodiments of the present application, the litter basin assembly 10 further comprises a feces collecting basin 15 which is detachably arranged between the two shelf plates 13 to form the second accommodating space 12. That is, the feces collecting basin 15 can be detached by the user from the two shelf plates 13, so as to facilitate the user to dispose the fecal pellets collected in the feces collecting basin 15, prevent the fecal pellets from being accumulated for too long time to generate odor, and keep the environment clean. Moreover, the cleaning device 30 further comprises two connecting seats 33 which are fixedly connected to the two sides of the feces collecting basin 15, and the two ends of the first horizontal rod 321 are rotatably installed in the two connecting seats 33, so that the first horizontal rod 321 can be smoothly reciprocated between the first working position and the second working position. In the cleaning device 30 of the smart litter box, as shown in Figure 13 and Figure 14 the power structure 31 comprises a swing arm 311 and an elastic member 312, at least one end of the first horizontal rod 321 is fixedly connected with the swing arm 311, specifically, the swing arm 311 is locked on the end of the first horizontal rod 321 by a fastening screw 314, and the swing arm 311 is located between the shelf plate 13 and the feces collecting basin 15 to contact or disengage with the triggering part 221, and the elastic member 312 is arranged between the swing arm 311 and the feces collecting basin 15, and the elastic member 312 provides elastic force to reset the cleaning teeth 322 from the first working position to the second working position. When the sanding rake mechanism 20 moves to contact and trigger the swing arm 311, the sanding rake mechanism 20 continues to move to overcome the elastic force of the elastic member 312, the swing arm 311 drives the first horizontal rod 321 to rotate in the first direction W, so that the cleaning teeth 322 of the cleaning rake 32 are rotated from the initial working position (i.e. the second working position) to the first working position, so that the cleaning teeth 322 can avoid the rake teeth 212, and then the fecal pellets on the rake teeth 212 are smoothly poured into the second accommodating space 12. Then, the sanding rake mechanism 20 retreats to move so that the triggering part 221 disengages from the swing arm 311, the swing arm 311 drives the first horizontal rod 321 to reversely rotate (rotate in the direction opposite to the first direction W) under the action of the elastic force of the elastic member 312, so that the cleaning teeth 322 are restored from the first working position to the second working position, at this time, the plurality of cleaning teeth 322 and the plurality of rake teeth 212 are alternately crossed. In this way, in the process of the rake teeth 212 retreating to the initial position, the cleaning teeth 322 scrape the fecal pellets adhered on the rake teeth 212 and collect them in the second accommodating space 12, so as to reduce the fecal pellets adhered on the rake teeth 212, reduce the possibility of the gap of the rake teeth 212 being blocked by the fecal pellets, enable the cat litter rake 21 to continuously maintain a high raking capacity, and reduce the waste caused by the cat litter being taken out by the fecal pellets adhered on the rake teeth 212.

[0060] The elastic member 312 is preferably a torsion spring. One end of the torsion spring abuts against the swing arm 311, and the other end of the torsion spring abuts against the litter box 14. The torsion spring provides sufficient elastic force to the swing arm 311, so that the cleaning teeth 322 of the cleaning rake 32 remain in the initial working position (i.e., the second working position) when no external force is applied. Of course, the elastic member 312 can also be a spiral tension spring, a spiral compression spring, a spring sheet, or any other component capable of providing sufficient elastic force, so that the cleaning teeth 322 of the cleaning rake 32 remain in the second working position when no external force is applied, which is not limited herein.

[0061] In some embodiments of the intelligent litter box machine, the litter box assembly 10 further comprises a litter box 14, which is detachably arranged between the two frame plates 13 to form the first accommodating space 11.

In addition, the cleaning device 30 further comprises two connecting seats 33, which are respectively fixedly connected to the two sides of the litter box 14. The two ends of the first horizontal rod 321 are respectively rotatably installed in the two connecting seats 33, so that the first horizontal rod 321 can smoothly reciprocate between the first working position and the second working position.

When the sand rake mechanism 20 moves to the actuating portion 221 to contact and trigger the trigger 316, the trigger 316 controls the driver 315 to start, and the driver 315 drives the first horizontal rod 321 to rotate in the first direction W, so that the cleaning teeth 322 of the cleaning rake 32 rotate from the initial working position (i.e. the second working position) to the first working position, so that the cleaning teeth 322 can avoid the rake teeth 212, and then the clumps on the rake teeth 212 are smoothly poured into the second containing space 12. Then, the sand rake mechanism 20 moves back to make the actuating portion 221 disengage from the trigger 316, the trigger 316 cancels the control of the driver 315, and then the driver 315 drives the first horizontal rod 321 to rotate reversely (rotate in the direction opposite to the first direction W), so that the cleaning teeth 322 return from the first working position to the second working position, at this time, the plurality of cleaning teeth 322 and the plurality of rake teeth 212 are alternately crossed. In this way, during the rake teeth 212 return to the initial position, the cleaning teeth 322 scrape the clumps adhered on the rake teeth 212 and collect them in the second containing space 12, so as to reduce the clumps adhered on the rake teeth 212, reduce the possibility of the gap of the rake teeth 212 being blocked by the clumps, enable the litter rake 21 to continuously maintain a high rake filtering capacity, and reduce the waste caused by the litter being taken out by the clumps adhered on the rake teeth 212.

[0062] In some embodiments of the intelligent litter machine, the litter box assembly 10 further comprises a clump collecting box 15, which is detachably arranged between the two shelf plates 13 to form the second containing space 12. That is, the clump collecting box 15 can be detached from the two shelf plates 13 by the user, so as to facilitate the user to handle the clumps collected in the clump collecting box 15, prevent the clumps from being accumulated for too long time to produce odor, and keep the environment clean. In addition, the cleaning device 30 further comprises two connecting seats 33, which are respectively fixedly connected to the two sides of the clump collecting box 15, and the two ends of the first horizontal rod 321 are respectively rotatably mounted on the two connecting seats 33, so that the first horizontal rod 321 can be smoothly changed between the first working position and the second working position.

When the rake mechanism 20 moves to the touch part 221 to contact and trigger the trigger 316, the trigger 316 controls the driver 315 to start, and the driver 315 drives the first horizontal rod 321 to rotate in the first direction W, so that the cleaning teeth 322 of the cleaning rake 32 rotate from the initial working position (i.e. the second working position) to the first working position, so that the cleaning teeth 322 can avoid the rake teeth 212, and then smoothly dump the feces on the rake teeth 212 into the second containing space 12. Then, the rake mechanism 20 moves back to make the touch part 221 disengage from the trigger 316, and the trigger 316 cancels the control of the driver 315, and then the driver 315 drives the first horizontal rod 321 to rotate reversely (rotate in the direction opposite to the first direction W), so that the cleaning teeth 322 return from the first working position to the second working position, at this time, the plurality of cleaning teeth 322 and the plurality of rake teeth 212 are alternately crossed. In this way, during the rake teeth 212 return to the initial position, the cleaning teeth 322 scrape the feces adhered on the rake teeth 212 and collect them in the second containing space 12, thereby reducing the feces adhered on the rake teeth 212, reducing the possibility of the gap of the rake teeth 212 being blocked by the feces, so that the litter rake 21 can continuously maintain a high rake filtering capacity, and reduce the waste caused by the cat litter being taken out by the feces adhered on the rake teeth 212.

[0063] In some other embodiments of the intelligent cat litter machine of the present application, as shown in FIG. 9, the power structure 31 is mounted on the shelf plate 13, the power structure 31 comprises a driver 315 and a trigger 316, the driver 315 is electrically connected with the trigger 316, the trigger 316 is located between the shelf plate 13 and the litter basin 15 to contact or separate with the touch part 221, and the driver 315 is drivingly connected with the end of the first horizontal rod 321 through a power output part 3151 when the litter basin 15 is placed between the two shelf plates 13, and the power output part 3151 of the driver 315 is detachable from the first horizontal rod 321, wherein the power output part 3151 comprises but is not limited to a shaft coupling. When the rake mechanism 20 moves to the touch part 221 to contact and trigger the trigger 316, the trigger 316 controls the driver 315 to start, and the driver 315 drives the first horizontal rod 321 to rotate in the first direction W, so that the cleaning teeth 322 of the cleaning rake 32 rotate from the initial working position (i.e. the second working position) to the first working position, so that the cleaning teeth 322 can avoid the rake teeth 212, and then smoothly dump the feces on the rake teeth 212 into the second containing space 12. Then, the rake mechanism 20 moves back to make the touch part 221 disengage from the trigger 316, and the trigger 316 cancels the control of the driver 315, and then the driver 315 drives the first horizontal rod 321 to rotate reversely (rotate in the direction opposite to the first direction W), so that the cleaning teeth 322 return from the first working position to the second working position, at this time, the plurality of cleaning teeth 322 and the plurality of rake teeth 212 are alternately crossed. In this way, during the rake teeth 212 return to the initial position, the cleaning teeth 322 scrape the feces adhered on the rake teeth 212 and collect them in the second containing space 12, thereby reducing the feces adhered on the rake teeth 212, reducing the possibility of the gap of the rake teeth 212 being blocked by the feces, so that the litter rake 21 can continuously maintain a high rake filtering capacity, and reduce the waste caused by the cat litter being taken out by the feces adhered on the rake teeth 212. Figure 1 , Figure 8 , Figure 9 , Figure 19 and Figure 20As shown, the intelligent cat litter machine further comprises a water supply device 40 and a flip cover device 50, the flip cover device 50 is reversibly installed on the two frame plates 13, and the flip cover device 50 is synchronously operated with the power structure 31 of the cleaning device 30, and the flip cover device 50 is used to cover the second containing space 12 and cover the cleaning rake 32 when the cat litter rake 21 exits the second containing space 12. That is, the flip cover device 50 is in a normally closed state of covering the second containing space 12 at ordinary times. When the sand rake mechanism 20 moves to contact and trigger the power structure 31 of the cleaning device 30 through the triggering part 221, the power structure 31 synchronously starts the flip cover device 50, and the flip cover device 50 opens the second containing space 12, so that the rake teeth 212 of the cat litter rake 21 can enter the second containing space 12 and dump the feces separated by the rake into the second containing space 12; when the sand rake mechanism 20 moves back to make the triggering part 221 disengage from the power structure 31 and the rake teeth 212 of the cat litter rake 21 completely exit the second containing space 12, the flip cover device 50 covers the second containing space 12 and covers the cleaning rake 32.

In this way, the water supply device 40 supplies water to the flow channel 3211, and the water flow is sprayed towards the cleaning teeth 322 for flushing, so as to flush away the residual cat feces adhered to the cleaning teeth 322 as much as possible, and make the cleaning teeth 322 as clean as possible, which can greatly reduce the frequency of taking out the cleaning rake 32 for deep cleaning, reduce the workload of the user, and improve the user experience. Moreover, since the flip cover device 50 covers the second containing space 12 and the cleaning rake 32, the water flow sprayed towards the cleaning teeth 322 is blocked by the flip cover device 50, avoiding the situation that the water flow splashes everywhere, and the water flow finally completely falls into the second containing space 12.

[0064] Moreover, in the intelligent cat litter machine of the present application, the flip cover device 50 keeps closing the second containing space 12 at ordinary times, covering the feces collected in the feces collecting basin 15. In this way, the environment is coordinated, and to some extent, the feces in the feces collecting basin 15 can prevent the emission of odor to pollute the air, keeping the environment fresh.

[0065] In order to prevent the accumulated water in the second containing space 12 from emitting odor, the sand basin assembly 10 of the intelligent cat litter machine is provided with a sewage discharge device (not shown), which collects or directly discharges the sewage falling into the second containing space 12 to the sewer. In this way, the sewage is collected or directly discharged, avoiding the situation that the accumulated water emits odor.
