Description

Technical Field

[0001] The present application belongs to the technical field of pet equipment, and in particular, relates to an intelligent cat litter machine. Background Art

[0002] With the continuous improvement of living standards, more and more families choose pets as daily companions, especially in economically developed cities, where the proportion of people raising pets is relatively high. Among them, because cats habitually use sand to bury their excrement after defecation, which is a clean behavior, and cats are cute and adorable, more and more people like to keep pet cats.

[0003] People who keep pet cats usually use cat litter boxes for their pet cats to defecate in, so that the pet cats can bury their excrement after defecation, so that people's living environment can be kept clean. After the pet cat has defecated 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 feces buried in the cat litter in the cat litter box will accumulate a lot, affecting the pet cat's continued defecation. Therefore, smart cat litter machines on the market came into being. After each defecation of the pet cat, the smart cat litter machine can rake and filter the feces buried in the cat litter, thereby avoiding the accumulation of a large number of feces buried in the cat litter. In this way, it is not only convenient for the pet cat to continue to defecate, but also can reduce the frequency of cleaning or replacing the cat litter.

[0004] However, in the process of cleaning cat litter, the cat litter rake of the current intelligent cat litter machine may have feces stuck on the rake teeth. If the feces stuck on the cat litter rake are not cleaned in time, the feces will block the rake teeth gap, which will increase the resistance of the cat litter rake in the subsequent process of raking and filtering cat litter, resulting in a decrease in the raking and filtering capacity of the cat litter rake. In addition, the blocked rake teeth gap will rake out the cat litter and feces together, resulting in a waste of cat litter. Summary of the invention

[0052] like Figures 1 to 12As shown, the smart cat litter machine provided in the embodiment of the present application includes a litter box assembly 10, a sand rake mechanism 20 and a cleaning device 30. The litter box assembly 10 includes two opposite frame plates 13, and the two frame plates 13 provide support for the entire smart cat litter machine so that it can be placed firmly on the ground. In addition, a first accommodating space 11 and a second accommodating space 12 are provided between the two frame plates 13. The first accommodating space 11 is used to accommodate cat litter, wherein cat litter is a sanitary product designed for pet cats to defecate, and is usually made of materials such as minerals, plant fibers, and silica gel. Therefore, the purchase of cat litter is an important part of the cost of raising cats. The second accommodating space 12 is used to collect cat feces separated from the cat litter by rake filtering, so as to facilitate the subsequent cleaning of cat feces. The sand rake mechanism 20 includes a power device 23, a cat litter rake 21 and two brackets 22. The two brackets 22 are slidably arranged on the two frame plates 13, respectively, and the brackets 22 are provided with a touch portion 221, and at least one bracket 22 is installed with a power device 23. The cat litter rake 21 includes a plurality of rake teeth 212, and the plurality of rake teeth 212 are used to rake and filter cat litter. The cleaning device 30 is installed on the litter box assembly 10. Specifically, the cleaning device 30 includes a power structure 31 and a cleaning rake 32 connected to the power structure 31. The cleaning rake 32 includes a plurality of cleaning teeth 322, and the plurality of cleaning teeth 322 extend toward the second accommodation space 12. In the process of the cat litter rake 21 filtering the cat litter, that is, the cat litter rake 21 moves along the cat litter box assembly 10. Figure 3 The cleaning rake 32 moves in the direction indicated by the middle arrow S1 and rakes and filters the cat litter. When the power structure 31 is triggered by the triggering part 221 and drives 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 separated from the triggering part 221 and drives the first crossbar 321 to rotate in the opposite direction, the plurality of cleaning teeth 322 are in the second working position to alternately cross with the plurality of rake teeth 212 in sequence, as shown in FIG. Figure 6 and Figure 7 As shown, the cleaning teeth 322 scrape the feces sticking to the rake teeth 212 and collect them in the second accommodating space 12 during the process of the rake teeth 212 retreating to the initial position (the rake teeth 212 retreat, that is, the cat litter rake 21 moves along the cat litter rake 212). Figure 6 Move in the direction indicated by arrow S2).

[0053] In the smart cat litter machine provided in the embodiment of the present application, after the pet cat finishes defecating in the cat litter each time, the cat litter rake 21 is driven by the power device 23 to move along the S1 direction on the frame plate 13, and the feces buried in the cat litter are raked and filtered for separation, and the power device 23 drives the cat litter rake 21 to transfer and dump the feces separated by raking and filtering into the second storage space 12, so as to collect the feces in a centralized manner to facilitate the subsequent cleaning of the feces. In the cleaning device 30 of the smart cat litter machine, 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 sand rake mechanism 20 moves to the second storage space 12. When the sand rake mechanism 20 moves to the point where the trigger portion 221 contacts and triggers the power structure 31 of the cleaning device 30, the power structure 31 starts 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 feces on the rake teeth 212 are smoothly dumped into the second accommodating space 12. Figure 4 , Figure 5 and Figure 8 Then, the sand rake mechanism 20 moves backward so that the triggering portion 221 is separated from the power structure 31, and the power structure 31 drives the cleaning rake 32 to rotate in the opposite direction (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 sequence, as shown in FIG. Figure 6 and Figure 7 In this way, when the rake teeth 212 retract to the initial position, the cleaning teeth 322 scrape the feces sticking to the rake teeth 212 and collect them in the second accommodating space 12, thereby reducing the feces sticking to the rake teeth 212 and reducing the possibility of the gaps between the rake teeth 212 being blocked by feces, so that the cat litter rake 21 can continue to maintain a high raking and filtering capacity, and reduce the waste of cat litter caused by feces sticking to the rake teeth 212.

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

[0055] In the smart cat litter machine of the embodiment of the present application, Figures 1 to 10 As shown, the litter box assembly 10 also includes a cat litter box 14, which is detachably arranged between the two racks 13 to form a first accommodation space 11. That is, the cat litter box 14 can be removed from the two racks 13 by the user, so that the user can deeply clean the cat litter in the cat litter box 14 or replace it with new cat litter, prevent the cat litter from generating 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 box 14 facing the second accommodation space 12. In this way, when the cat litter box 14 is removed from the two racks 13 by the user, the cleaning rake 32 is also taken out. Since the cleaning teeth 322 of the cleaning rake 32 will inevitably stick to the residual cat feces when scraping off the feces sticking to the rake teeth 212, the cleaning rake 32 is taken out with the cat litter box 14, so that the user can clean the cleaning rake 32 and clean the residual cat feces sticking to the cleaning teeth 322.

[0056] like Figures 10 to 12 As shown, the cleaning device 30 also includes two connecting seats 33, and the two connecting seats 33 are respectively fixedly connected to the two sides of the cat litter box 14. In addition, the two ends of the first cross bar 321 are rotatably mounted on the two connecting seats 33, so that the first cross bar 321 can smoothly reciprocate between the first working position and the second working position. Figures 10 to 12As shown, the power structure 31 includes a swing arm 311 and an elastic member 312. At least one end of the first cross bar 321 is fixedly connected to the swing arm 311. Specifically, the swing arm 311 is locked on the end of the first cross bar 321 by a fastening screw 314. The swing arm 311 is located between the frame 13 and the cat litter box 14 to contact or disengage with the trigger part 221. The elastic member 312 is arranged between the swing arm 311 and the cat litter box 14. 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 sand rake mechanism 20 moves along the S1 direction until the triggering portion 221 contacts and triggers the swing arm 311, the sand rake mechanism 20 continues to move and overcomes the elastic force of the elastic member 312, and 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 feces on the rake teeth 212 into the second accommodating space 12. Then, the sand rake mechanism 20 moves back along the S2 direction so that the triggering portion 221 is separated from the swing arm 311. The swing arm 311 drives the first cross bar 321 to rotate in the opposite direction (rotate in the opposite direction of the first direction W) under the elastic force of the elastic member 312, 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 sequence, such as Figure 6 and Figure 7 In this way, when the rake teeth 212 retract to the initial position, the cleaning teeth 322 scrape the feces sticking to the rake teeth 212 and collect them in the second accommodating space 12, thereby reducing the feces sticking to the rake teeth 212 and reducing the possibility of the gaps between the rake teeth 212 being blocked by feces, so that the cat litter rake 21 can continue to maintain a high raking and filtering capacity, and reduce the waste of cat litter caused by feces sticking to the rake teeth 212.

[0057] In the smart cat litter machine of the embodiment of the present application, Figures 2 to 7 , Fig. 9 As shown, the litter box assembly 10 further includes a stool collecting bowl 15, which is detachably arranged between the two racks 13 to form a second accommodating space 12. In this way, the stool collecting bowl 15 can be removed from the two racks 13 by the user, so that the user can conveniently process the stool collected in the stool collecting bowl 15, prevent the stool from accumulating too much and generating odor for too long, and keep the environment clean.

[0058] In some embodiments of the smart cat litter machine of the present application, the cleaning device 30 further includes two connecting seats 33, and the two connecting seats 33 are respectively fixedly connected to the two sides of the cat litter box 14. In addition, the two ends of the first cross bar 321 are respectively rotatably mounted on the two connecting seats 33, so that the first cross bar 321 can smoothly switch back and forth between the first working position and the second working position. Figure 15 to Figure 16 As shown, the power structure 31 includes a swing arm 311, an elastic member 312 and an adapter 313. The swing arm 311 is rotatably connected to the frame 13. The swing arm 311 is located between the frame 13 and the cat litter box 14 to contact or disengage with the trigger portion 221. The adapter 313 is fixedly connected to the swing arm 311. The elastic member 312 is arranged between the swing arm 311 and the frame 13. Moreover, when the cat litter box 14 is placed between the two frame plates 13, the adapter 313 is connected to the end of the first cross bar 321 so that the adapter 313 and the first cross bar 321 rotate synchronously with the swing arm 311. 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 sand rake mechanism 20 moves to the point where the triggering portion 221 contacts and triggers the swing arm 311, the sand rake mechanism 20 continues to move and overcomes the elastic force of the elastic member 312, and the swing arm 311 drives the first crossbar 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 accommodating space 12. Then, the sand rake mechanism 20 moves back to make the triggering portion 221 separate from the swing arm 311, and the swing arm 311 drives the first crossbar 321 to rotate in the opposite direction (rotate in the opposite direction of the first direction W) under the elastic force of the elastic member 312, so that the cleaning teeth 322 return from the first working position to the second working position, and at this time, the plurality of cleaning teeth 322 and the plurality of rake teeth 212 are alternately crossed in sequence. In this way, when the rake teeth 212 retract to the initial position, the cleaning teeth 322 scrape the feces stuck on the rake teeth 212 and collect them in the second accommodating space 12, thereby reducing the feces stuck on the rake teeth 212 and reducing the possibility of the gaps between the rake teeth 212 being blocked by feces, so that the cat litter rake 21 can continue to maintain a high raking and filtering capacity and reduce the waste caused by cat litter being carried out by feces stuck on the rake teeth 212.

[0059] In other embodiments of the smart cat litter machine of the present application, the litter box assembly 10 also includes a feces collecting bowl 15, which is detachably arranged between the two frames 13 to form a second accommodating space 12. That is to say, the feces collecting bowl 15 can be removed from the two frames 13 by the user, so as to facilitate the user to process the feces collected in the feces collecting bowl 15, prevent the feces from accumulating too much and for too long to produce odor, and keep the environment clean. In addition, the cleaning device 30 also includes two connecting seats 33, which are respectively fixedly connected to the two sides of the feces collecting bowl 15, and the two ends of the first cross bar 321 are respectively rotatably installed on the two connecting seats 33, so that the first cross bar 321 can smoothly reciprocate between the first working position and the second working position. In the cleaning device 30 of the smart cat litter machine, Fig.13 and Fig.14 As shown, the power structure 31 includes a swing arm 311 and an elastic member 312. At least one end of the first cross bar 321 is fixedly connected to the swing arm 311. Specifically, the swing arm 311 is locked on the end of the first cross bar 321 by a fastening screw 314, and the swing arm 311 is located between the frame 13 and the feces collecting bowl 15 to contact or disengage with the trigger portion 221. The elastic member 312 is arranged between the swing arm 311 and the feces collecting bowl 15. The elastic member 312 provides elastic force to reset the cleaning tooth 322 from the first working position to the second working position. When the sand rake mechanism 20 moves to the point where the triggering portion 221 contacts and triggers the swing arm 311, the sand rake mechanism 20 continues to move and overcomes the elastic force of the elastic member 312, and the swing arm 311 drives the first crossbar 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 accommodating space 12. Then, the sand rake mechanism 20 moves back to make the triggering portion 221 separate from the swing arm 311, and the swing arm 311 drives the first crossbar 321 to rotate in the opposite direction (rotate in the opposite direction of the first direction W) under the elastic force of the elastic member 312, so that the cleaning teeth 322 return from the first working position to the second working position, and at this time, the plurality of cleaning teeth 322 and the plurality of rake teeth 212 are alternately crossed in sequence. In this way, when the rake teeth 212 retract to the initial position, the cleaning teeth 322 scrape the feces stuck on the rake teeth 212 and collect them in the second accommodating space 12, thereby reducing the feces stuck on the rake teeth 212 and reducing the possibility of the gaps between the rake teeth 212 being blocked by feces, so that the cat litter rake 21 can continue to maintain a high raking and filtering capacity and reduce the waste caused by cat litter being carried out by feces stuck 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 cat 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 helical tension spring, a helical compression spring, a spring sheet, or other components that can provide 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 here.

[0061] In some other embodiments of the smart cat litter machine of the present application, the litter box assembly 10 also includes a cat litter box 14, which is detachably arranged between the two frame plates 13 to form a first accommodating space 11. That is to say, the cat litter box 14 can be removed from the two frame plates 13 by the user, so as to facilitate the user to deeply clean the cat litter in the cat litter box 14 or replace it with new cat litter, prevent the cat litter from generating odor due to long-term use, and keep the environment clean. In addition, the cleaning device 30 also includes two connecting seats 33, and the two connecting seats 33 are respectively fixedly connected to the two sides of the cat litter box 14, and the two ends of the first cross bar 321 are respectively rotatably installed on the two connecting seats 33, so that the first cross bar 321 can smoothly reciprocate between the first working position and the second working position. In the cleaning device 30 of the smart cat litter machine, Fig.17 and Fig.18As shown, the power structure 31 is installed on the frame 13, and the power structure 31 includes a driver 315 and a trigger 316. The driver 315 is electrically connected to the trigger 316. The trigger 316 is located between the frame 13 and the cat litter box 14 to contact or separate from the trigger portion 221. Moreover, when the cat litter box 14 is placed between the two frame plates 13, the driver 315 is drivingly connected to the end of the first crossbar 321, and the driver 315 is separable from the first crossbar 321. When the sand rake mechanism 20 moves to contact the trigger portion 221 and triggers the trigger 316, the trigger 316 controls the driver 315 to start, and the driver 315 drives the first crossbar 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 accommodating space 12. Then, the sand rake mechanism 20 moves backward so that the touch part 221 is separated from the trigger 316, and the trigger 316 cancels the control of the driver 315, and the driver 315 drives the first crossbar 321 to rotate in the opposite direction (rotate in the opposite direction of 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 sequence. In this way, when the rake teeth 212 retreat to the initial position, the cleaning teeth 322 scrape the feces sticking to the rake teeth 212 and collect them in the second accommodating space 12, thereby reducing the feces sticking to the rake teeth 212 and reducing the possibility of the gaps of the rake teeth 212 being blocked by feces, so that the cat litter rake 21 can continue to maintain a high rake filtering capacity and reduce the waste caused by the feces sticking to the rake teeth 212.

[0062] In some other embodiments of the smart cat litter machine of the present application, the litter box assembly 10 also includes a feces collecting bowl 15, which is detachably arranged between the two frames 13 to form a second accommodating space 12. In other words, the feces collecting bowl 15 can be removed from the two frames 13 by the user, so as to facilitate the user to process the feces collected in the feces collecting bowl 15, prevent the feces from accumulating too much and for too long to generate odor, and keep the environment clean. In addition, the cleaning device 30 also includes two connecting seats 33, which are respectively fixedly connected to the two sides of the feces collecting bowl 15, and the two ends of the first cross bar 321 are respectively rotatably installed on the two connecting seats 33, so that the first cross bar 321 can smoothly reciprocate between the first working position and the second working position. In the cleaning device 30 of the smart cat litter machine, Fig.17 and Fig.18As shown, the power structure 31 is installed on the frame 13, and the power structure 31 includes a driver 315 and a trigger 316. The driver 315 is electrically connected to the trigger 316. The trigger 316 is located between the frame 13 and the toilet bowl 15 to contact or separate from the trigger part 221. In addition, when the toilet bowl 15 is placed between the two frames 13, the driver 315 is driven and connected to the end of the first cross bar 321 through the power output part 3151, and the power output part 3151 of the driver 315 is separable from the first cross bar 321, wherein the power output part 3151 includes but is not limited to a coupling. When the sand rake mechanism 20 moves to the point where the trigger 221 contacts and triggers the trigger 316, the trigger 316 controls the driver 315 to start, and the driver 315 drives the first crossbar 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 accommodating space 12. Then, the sand rake mechanism 20 moves back to make the trigger 221 disengage from the trigger 316, and the trigger 316 cancels the control of the driver 315, and the driver 315 drives the first crossbar 321 to rotate in the opposite direction (rotate in the opposite direction of the first direction W), so that the cleaning teeth 322 return from the first working position to the second working position, and at this time, the plurality of cleaning teeth 322 and the plurality of rake teeth 212 alternately cross in sequence. In this way, when the rake teeth 212 retract to the initial position, the cleaning teeth 322 scrape the feces stuck on the rake teeth 212 and collect them in the second accommodating space 12, thereby reducing the feces stuck on the rake teeth 212 and reducing the possibility of the gaps between the rake teeth 212 being blocked by feces, so that the cat litter rake 21 can continue to maintain a high raking and filtering capacity and reduce the waste caused by cat litter being carried out by feces stuck on the rake teeth 212.

[0063] In some other embodiments of the present application, the intelligent cat litter machine, such as Figure 1 , Figure 8 , Fig. 9 , Fig.19 and Fig. 20As shown, the intelligent cat litter machine further includes a water supply device 40 and a flip cover device 50, which can be flipped and installed on the two frame plates 13, and the flip cover device 50 and the power structure 31 of the cleaning device 30 operate synchronously, and the flip cover device 50 is used to cover the second accommodation space 12 and the cleaning rake 32 when the cat litter rake 21 exits the second accommodation space 12. That is to say, the flip cover device 50 is in a normally closed state of covering the second accommodation space 12 at ordinary times. When the sand rake mechanism 20 moves to the point where the trigger portion 221 contacts and triggers the power structure 31 of the cleaning device 30, the power structure 31 and the flip cover device 50 are started synchronously, and the flip cover device 50 opens the second storage space 12, so that the rake teeth 212 of the cat litter rake 21 can enter the second storage space 12 and dump the feces separated by the rake filter into the second storage space 12; when the sand rake mechanism 20 moves backward so that the trigger portion 221 is separated from the power structure 31 and the rake teeth 212 of the cat litter rake 21 completely withdraw from the second storage space 12, the flip cover device 50 covers the second storage space 12 and covers the cleaning rake 32. In the cleaning device 30 of the smart cat litter machine, the water supply device 40 includes a water supply pipe 41, the first cross bar 321 is provided with a flow channel 3211 and a plurality of water outlets 3212 connected to the flow channel 3211, the plurality of water outlets 3212 correspond to the plurality of cleaning teeth 322 one by one, and the water outlets 3212 are arranged to face the cleaning teeth 322, and the water supply pipe 41 is connected to the flow channel 3211. In this way, the water supply device 40 supplies water to the flow channel 3211, and the water flow sprays toward the cleaning teeth 322 for flushing, and the residual cat feces adhering to the cleaning teeth 322 are flushed away as much as possible, and the cleaning teeth 322 are kept 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's use experience. Furthermore, since the flip cover device 50 covers the second accommodating space 12 and the cleaning rake 32 , the water flow sprayed toward the cleaning teeth 322 is blocked by the flip cover device 50 , thereby preventing the water flow from splashing everywhere, and the water flow finally falls completely into the second accommodating space 12 .

[0064] Moreover, in the smart cat litter machine of the present application, the flip cover device 50 keeps the second accommodation space 12 closed at ordinary times, and covers the feces collected in the collecting bowl 15. This makes the environment harmonious, and to a certain extent can prevent the feces in the collecting bowl 15 from emitting odor and polluting the air, keeping the ambient air fresh.

[0065] In order to prevent the accumulation of water and stink in the second storage space 12, the litter box assembly 10 of the smart cat litter machine is provided with a sewage discharge device (not shown) to collect or directly discharge the sewage falling into the second storage space 12 into the sewer. In this way, the sewage is collected or directly discharged to avoid the accumulation of water and stink. The sewage discharge device includes but is not limited to a sewage tank or a sewage discharge pipeline, which is not limited here.

[0066] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
