Description

Technical Field

[0001] This utility model relates to the technical field of pet litter boxes, and more particularly to a pet litter box. Background Technology

[0002] As people's living standards improve, their demands for spiritual well-being also increase, leading to a rise in pet ownership (such as cats, rabbits, or dogs). Consequently, the demand for pet litter boxes for collecting feces and urine is also growing. Taking cat litter boxes as an example, these boxes are used in conjunction with cat litter as a toilet. To use them, cat litter is poured into the litter trough. The cat then urinates or defecates in the trough, mixing with the litter to form a litter ball. After the cat finishes and leaves, the litter ball containing feces and urine is pushed manually or electrically into a collection chamber on one side, where it is collected. Currently, the collection chamber lacks a locking mechanism, which means it may open outwards due to vibrations from the litter box's motorized operation. Alternatively, the cat may pull out the collection chamber out of curiosity, making it unreliable for collecting pet waste. Furthermore, an opened collection chamber releases unpleasant odors, significantly impacting the user experience. Therefore, existing pet litter boxes need improvement. Utility Model Content

[0003] This utility model provides a pet litter box, which mainly solves the technical problem of how to lock the waste collection chamber after it is installed in the main body of the litter box while also making it easy for the user to operate.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A pet litter box includes a litter box body, a waste collection chamber, a chamber door, and a locking mechanism; the litter box body has an upward-opening sand trough, the waste collection chamber is detachably connected to the litter box body, the waste collection chamber has a waste collection groove inside, the chamber door is movably connected to the litter box body and is used to cover the opening of the waste collection groove, the locking mechanism is disposed at the bottom of the waste collection chamber, and the bottom of the litter box body has a locking hole for the locking mechanism to be inserted;

[0006] The locking mechanism includes a button, a telescopic member, and an elastic member. The button and the telescopic member are slidably connected to the waste collection chamber in the longitudinal direction. The telescopic member is located above the button and is fitted with the elastic member. The telescopic member has a downward movement tendency due to the elastic force of the elastic member. The button is used to push the telescopic member to move upward. The waste collection chamber has multiple downwardly inclined guide slopes arranged circumferentially along the downward movement path of the telescopic member. The telescopic member slides downward along the guide slopes to a first position or a second position higher than the first position due to the elastic force of the elastic member. When the telescopic member is in the second position, it is inserted into the locking hole. When the telescopic member is in the first position, it disengages outward relative to the locking hole.

[0007] In one of the technical solutions, the waste collection chamber includes a bottom shell and a top shell that are fixedly connected. The bottom of the bottom shell is provided with a first through hole that extends upwards, and the top shell is provided with a second through hole that extends vertically at a position corresponding to the first through hole.

[0009] In one technical solution, a plurality of guide blocks are protruding from the wall of the first hole and spaced apart circumferentially. The top of the guide block is provided with the guide slope. The outer wall of the telescopic member is provided with a first slot that opens downward circumferentially. A second slot that opens downward is provided between two adjacent first slots. The upward extension depth of the first slot is greater than the upward extension depth of the second slot. The slot walls of the first slot and the slot walls of the second slot are provided with mating slopes parallel to the guide slope. The end of the button facing the telescopic member is provided with a plurality of circumferentially arranged serrations for driving the telescopic member to move upward by pressing the mating slope. When the guide block is embedded in the first slot, the telescopic member is in the first position. When the guide block is embedded in the second slot, the telescopic member is in the second position.

[0010] In one of the technical solutions, the number of the first card slot, the second card slot, and the guide block are all equal.

[0011] In one of the technical solutions, a sliding groove is provided between the two guide blocks in the first hole. The sliding groove extends in the longitudinal direction. The outer wall of the button is provided with a plurality of sliders arranged in the circumferential direction. The plurality of sliders slide into the sliding groove from top to bottom in a corresponding manner.

[0012] In one of the technical solutions, the main body of the sand basin includes a shell, a drive mechanism and a waste cleaning component, and the waste collection trough is disposed at an adjacent position to the sand trough along a first direction;

[0013] The waste cleaning assembly includes a movable seat and a waste shoveling component. The movable seat is slidably connected to the housing along the first direction. The driving mechanism is connected to the movable seat and is used to drive the waste cleaning assembly to reciprocate linearly along the first direction. The waste shoveling component extends into the sand trough and is slidably connected to the movable seat longitudinally. The housing is provided with guide grooves on two opposite inner sides. The bottom end of the guide groove extends to the path of the waste shoveling component moving along the first direction. The guide groove extends upward towards the waste collection chamber. The bottom surface of the sand trough includes an inclined surface that extends upward and gradually approaches the opening of the waste collection chamber.

[0014] In one of the technical solutions, the shovel component includes a mounting base and a shovel body. The mounting base and the movable base are slidably connected in the longitudinal direction, and the shovel body is rotatably connected to the mounting base and can swing in the first direction.

[0015] In one technical solution, racks are provided on both sides of the sand trough in a second direction, which is perpendicular to the first direction. The drive mechanism is housed within the movable seat. The drive mechanism includes a motor, a drive gear, a transmission gear, a transmission rod, and a traveling gear. The motor is fixedly connected to the movable seat, and the transmission rod is rotatably connected to the movable seat. Both ends of the transmission rod in the length direction extend beyond the movable seat along the second direction. The transmission gear is sleeved and fixed on the transmission rod. The drive gear is connected to the motor and meshes with the transmission gear. Both ends of the transmission rod in the length direction are sleeved and fixed with the traveling gear, which meshes with a corresponding rack.

[0016] In one of the technical solutions, the housing includes an outer shell and a sand chamber placed inside the outer shell, the sand chamber being provided with the sand trough, and the sand chamber being longitudinally detachable relative to the outer shell;

[0017] The shovel component is slidably connected to the side of the movable seat facing the collection chamber. The inner sidewall of the outer shell is provided with a mounting and disassembly groove that runs through both the top and bottom. When the cleaning component is reset to its initial position in the opposite direction of the first direction, the movable seat is located outside the path of the sand chamber moving upward, and the end of the shovel component in the length direction is located below the mounting and disassembly groove.

[0018] In one of the technical solutions, the main body of the sand basin also includes a first sensor and a second sensor. During the movement of the cleaning component in the sand trough, the sand trough is divided into a first space and a second space arranged adjacent to each other along the first direction. The first sensor and the second sensor are disposed on the housing or on the moving base. The first sensor is used to detect biometric information in the first space, and the second sensor is used to detect biometric information in the second space. Both the first sensor and the second sensor are signal connected to the drive mechanism.

[0019] Compared with the prior art, the pet litter box provided by this utility model has at least the following beneficial effects:

[0020] This design incorporates a locking mechanism on the waste collection chamber, specifically designed with a button, a telescopic component, and a spring-loaded component. When the button is pressed upwards, the telescopic component compresses the spring-loaded component. Upon releasing the button, the telescopic component moves downwards along the guide slope under the elastic force of the spring-loaded component, moving to either the first or second position. In practice, when the waste collection chamber needs to be removed for cleaning, the user simply presses the button upwards and releases it, allowing the telescopic component to remain in the higher second position. At this point, the telescopic component inserts into the locking hole of the litter box body, and the waste collection chamber is locked and cannot be removed. When the waste collection chamber needs to be removed, the user simply presses the button upwards again and releases it, allowing the telescopic component to remain in the lower first position. At this point, the telescopic component disengages from the locking hole, and the waste collection chamber is unlocked and can be removed. This solution specifically implements the function of locking the waste collection tank, and users can easily switch between the locked and unlocked states by simply pressing a button. Therefore, this solution has the advantage of being easy for users to operate. Attached Figure Description

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0047] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0048] Please refer to the following: Figure 1 , Figures 10 to 15 This utility model provides a pet litter box, mainly including a litter box body 300, a waste collection chamber 2, a chamber door 200, and a locking mechanism 400. The litter box body 300 is provided with an upwardly opening sand trough 11. The waste collection chamber 2 is detachably connected to the litter box body 300 and is provided with a waste collection groove 21 inside the waste collection chamber 2. The chamber door 200 is movably connected to the litter box body 300 and is used to cover the opening of the waste collection groove 21. In this embodiment, the chamber door 200 is preferably designed to be rotatably connected to the litter box body 300 so that the opening of the waste collection groove 21 can be opened by flipping the chamber door 200. The locking mechanism 400 is designed at the bottom of the waste collection chamber 2, and the bottom of the litter box body 300 is provided with a locking hole 301 for the locking mechanism 400 to be inserted.

[0049] The locking mechanism 400 specifically includes a button 401, a telescopic member 402, and an elastic member 403. Both the button 401 and the telescopic member 402 are slidably connected to the waste collection chamber 2 in the longitudinal direction. The telescopic member 402 is positioned above the button 401, and the aforementioned elastic member 403 is sleeved on the telescopic member 402. The elastic member 403 is preferably a spring. The telescopic member 402, under the elastic force of the elastic member 403, has a downward tendency to move. The button 401 is used to push the telescopic member 402 upward, so that the telescopic member 402 can compress the elastic member 403 upward. Furthermore, the waste collection chamber 2... Multiple guide slopes 22, which are spaced apart in the circumferential direction and all inclined downward, are provided on the path of the telescopic member 402 moving downward. After being subjected to the elastic force of the elastic member 403, the telescopic member 402 will move downward along the guide slope 22 to a first position or a second position. The second position is higher than the first position. It can be understood that when the telescopic member 402 is in the second position, it extends upward relative to the collection chamber 2. At this time, the telescopic member 402 is used to insert into the locking hole 301. When the telescopic member 402 is in the first position, the telescopic member 402 will disengage downward relative to the locking hole 301.

[0050] Specifically, this solution includes a locking mechanism 400 on the waste collection chamber 2. The locking mechanism 400 is designed to include a button 401, a telescopic member 402, and an elastic member 403. When the button 401 is pressed upwards, the telescopic member 402 compresses the elastic member 403. When the button 401 is released, the telescopic member 402 moves downwards along the guide slope 22 under the elastic force of the elastic member 403, allowing it to move downwards to either a first or second position. In practice, when the waste collection chamber 2 needs to be removed for cleaning... The user simply presses and releases button 401 upwards, causing the telescopic component 402 to stop at the higher second position. At this point, the telescopic component 402 inserts into the locking hole 301 of the litter box body 300, and the waste collection chamber 2 is locked and cannot be removed. To remove the waste collection chamber 2, the user simply presses and releases button 401 upwards again, causing the telescopic component 402 to stop at the lower first position. The telescopic component 402 then disengages downwards from the locking hole 301, and the waste collection chamber 2 is unlocked and can be removed. This solution effectively locks the waste collection chamber 2, and the user can easily switch between the locked and unlocked states by pressing button 401, making it user-friendly.

[0051] Please refer to the following: Figures 11 to 15 The waste collection chamber 2 specifically includes a bottom shell 23 and a top shell 24. The top shell 24 is located on top of the bottom shell 23 and is fixedly connected to the bottom shell 23. The bottom of the bottom shell 23 is provided with a first through hole 231 extending upwards, and the bottom of the top shell 24 is provided with a second through hole 241 extending vertically. The second through hole 241 is designed to correspond to and communicate with the first through hole 231. When the waste collection chamber 2 is installed into the sand basin body 300, the locking hole 301 is actually located directly above the second through hole 241. The button 401 is housed in the first through hole 231. The elastic member 403 is housed in the second hole 241 and abuts against the wall of the second hole 241. One part of the telescopic member 402 is housed in the first hole 231, and the other part of the telescopic member 402 is housed in the second hole 241. The guide slope 22 is actually designed in the first hole 231. When the telescopic member 402 is in the second position, the telescopic member 402 is actually exposed upward relative to the second hole 241. With this design, it is easy to process the guide slope 22 and easy to install the locking mechanism 400 in the waste collection chamber 2.

[0052] Please refer to them again. Figures 11 to 15The first hole 231 has a plurality of guide blocks 232 arranged circumferentially on its hole wall. The top of the guide block 232 is provided with the aforementioned guide slope 22. The outer wall of the telescopic member 402 is provided with a downwardly opening first slot 4021 along the circumferential direction. A downwardly opening second slot 4022 is provided between each two adjacent first slots 4021. The upward extension depth of the first slot 4021 is greater than the upward extension depth of the second slot 4022. The slot walls of the first slot 4021 and the slot walls of the second slot 4022 are provided with a mating slope 4023 parallel to the aforementioned guide slope 22. The end of the button 401 facing the telescopic member 402 (i.e., the top of the button 401) is provided with a plurality of circumferentially arranged serrations 4011. Specifically, when button 401 is pressed upwards, the serrations 4011 on button 401 will drive the telescopic member 402 to move upwards by pressing against the inclined surface 4023. When button 401 moves upwards to its final position, the telescopic member 402 will no longer be restricted by the guide block 232. The inclined surface 4023 of the telescopic member 402 will rotate slightly under the push of the serrations 4011. Then, simply release button 401, and the telescopic member 402 will be released under the elastic force of the elastic element 403. As the button 401 moves downwards, the inclined surface 4023 will naturally abut against the guide inclined surface 22. Guided by the guide inclined surface 22, the telescopic member 402 will rotate while moving downwards. Finally, the guide block 232 will be embedded in the first slot 4021 or the second slot 4022. When the guide block 232 is embedded in the first slot 4021, the telescopic member 402 is in the first position mentioned above. When the guide block 232 is embedded in the second slot 4022, the telescopic member 402 is in the second position mentioned above. In fact, after each press of the button 401, the telescopic member 402 will rotate by the same angle in the same direction. Moreover, the number of first slots 4021, second slots 4022 and guide blocks 232 are equal to ensure that after each press of the button 401, all guide blocks 232 are either embedded one-to-one in the respective first slots 4021 or one-to-one in the respective second slots 4022.

[0053] In other embodiments, the guide block 232 can also be designed on the telescopic member 402. In this case, the guide slope 22 needs to be designed at the lower end of the guide block 232. Correspondingly, the first slot 4021 and the second slot 4022 need to be designed in the first hole 231. Moreover, the first slot 4021 and the second slot 4022 need to be designed to open upward so that the guide block 232 on the telescopic member 402 can be inserted downward into the first slot 4021 or the second slot 4022.

[0054] Preferably, please refer to the following: Figure 11 and Figure 15In the first hole 231, a slide groove 233 is provided between the two guide blocks 232. The slide groove 233 extends in the longitudinal direction. The outer wall of the button 401 is provided with a plurality of sliders 4012 arranged in the circumferential direction. The plurality of sliders 4012 slide into the slide groove 233 from top to bottom in a corresponding manner to realize the sliding connection between the button 401 and the collection chamber 2 in the longitudinal direction.

[0055] Please refer to the following: Figure 1 , Figures 3 to 7 The main body 300 of the litter box also includes a housing 1, a drive mechanism 3 and a cleaning component 4. The collection trough 21 is arranged at an adjacent position to the litter trough 11 along the first direction X. The cleaning component 4 extends into the litter trough 11. The cleaning component 4 and the housing 1 are slidably connected along the first direction X directly or indirectly through connecting other components. The drive mechanism 3 is connected to the housing 1 and the cleaning component 4 respectively. The drive mechanism 3 is used to drive the cleaning component 4 to reciprocate linearly along the first direction X. Taking cat use as an example, when using the litter box 11, cat litter needs to be poured into the litter box 11 beforehand. The cat defecates and urinates in the litter box 11, and the feces and urine will mix with the cat litter to form a litter ball. After the cat finishes using the litter box and leaves, the litter cleaning component 4 will move in a straight line along the first direction X under the drive of the drive mechanism 3. The litter cleaning component 4 pushes the litter ball containing feces and urine into the litter collection chamber 2 on one side, and the litter collection chamber 2 collects the litter ball containing feces and urine. After the litter cleaning is completed, the litter cleaning component 4 will return to the initial position in the opposite direction of the first direction X under the drive of the drive mechanism 3.

[0056] Please refer to the following: Figure 1 , Figures 3 to 5 In this embodiment, the litter box body 300 also includes a first deodorizing box 7 and a second deodorizing box 8. The first deodorizing box 7 is detachably connected to the door 200 and is used to deodorize the waste collection trough 21. The second deodorizing box 8 is detachably connected to the side of the waste cleaning component 4 facing the waste collection trough 2 and is used to deodorize the litter trough 11. Specifically, this solution provides a first deodorizing box 7 on the door 200 to deodorize the waste collection trough 21, and a second deodorizing box 8 on the waste cleaning component 4 to deodorize the litter trough 11. By providing the first deodorizing box 7 and the second deodorizing box 8, it is beneficial to alleviate the odor released from the pet litter box during use, thereby improving the user experience. In addition, both the first deodorizing box 7 and the second deodorizing box 8 can be independently disassembled, allowing users to refill them with new deodorizing agent.

[0057] Please refer to the following: Figure 3 , Figure 6 and Figure 7The feces-cleaning component 4 specifically includes a movable seat 41 and a feces-shoveling component 42. The movable seat 41 is slidably connected to the housing 1 along the first direction X. The drive mechanism 3 is connected to the movable seat 41 and is used to drive the movable seat 41 to reciprocate along the straight line of the first direction X. The feces-shoveling component 42 extends into the sand trough 11 and is slidably connected to the movable seat 41 along the longitudinal direction. Preferably, the outer surface of the movable seat 41 is provided with a guide rail portion 411 extending longitudinally. The feces-shoveling component 42 slides down from this guide rail portion 411. The housing 1 is provided with guide grooves 12 on two opposite inner sides. The bottom end of the guide groove 12 extends to the path on which the feces-shoveling component 42 moves along the first direction X. The guide groove 12 extends upward at an incline toward the feces collection chamber 2. The bottom surface of the sand trough 11 includes an inclined surface 113 that extends upward and gradually approaches the opening of the feces collection trough 21. The inclined surface 113 is preferably extended in an arc shape. Specifically, after the cat finishes using the litter box 11, the litter-cleaning component 4, driven by the drive mechanism 3, moves to its end along the first direction X. The scooping component 42 then slides into the guide groove 12 and moves upwards under its guidance. Simultaneously, the scooping component 42 pushes the litter clump containing urine and feces upwards along the inclined surface 113 until it is pushed into the waste collection chamber 2 on one side. Through this design, the scooping component 42 essentially only pushes litter clumps containing urine and feces into the waste collection chamber 2, while normal litter without urine and feces is almost never pushed into it, thus reducing litter consumption. Preferably, the end of the shovel component 42 in the second direction Y (the second direction Y is perpendicular to the first direction X) is connected to a freely rotatable roller 43. The roller 43 is designed to slide along the guide groove 12 to prevent mutual wear between the shovel component 42 and the groove wall of the guide groove 12, while improving the smoothness of the shovel component 42 sliding along the guide groove 12.

[0058] Please refer to the following: Figure 6 and Figure 7The shovel component 42 includes a mounting base 421 and a shovel body 422. The mounting base 421 and the aforementioned movable base 41 are slidably connected in the longitudinal direction through a connecting guide rail 411. The shovel body 422 is rotatably connected to the mounting base 421. Moreover, the shovel body 422 can swing in the first direction X when rotating. In use, the scoop body 422 directly removes the litter clumps in the litter trough 11. By designing the scoop body 422 as a rotatable floating design, when the scoop body 422 moves in the opposite direction of the first direction X to reset, even if the scoop body 422 encounters a large obstacle (for example, if another cat enters the litter trough 11 to urinate or defecate while the scoop body 422 is moving in the first direction X, causing a new litter clump containing urine and feces to form in the litter trough 11), the scoop body 422 can automatically swing in the first direction X under the reaction force of the obstacle, so that the scoop body 422 can easily overcome the obstacle, thereby ensuring that the entire litter cleaning assembly 4 can reset to the initial position in the opposite direction of the first direction X, preventing the litter cleaning assembly 4 from being stuck in the middle position.

[0059] Please refer to the following: Figure 3 and Figure 4 In this embodiment, the main body 300 of the sand basin also includes a first sensor 5 and a second sensor 6. During the movement of the cleaning component 4 in the sand trough 11, the sand trough 11 is actually divided into a first space 111 and a second space 112. The first space 111 and the second space 112 are arranged adjacent to each other along the first direction X. The first sensor 5 and the second sensor 6 are set on the housing 1 or on the moving base 41. The first sensor 5 is used to detect the biometric information in the first space 111, and the second sensor 6 is used to detect the biometric information in the second space 112. The first sensor 5 and the second sensor 6 are both signal connected to the aforementioned drive mechanism 3. Specifically, during the movement of the litter cleaning component 4 along the first direction X, if a pet enters the litter box 11, the pet will be detected by either the first sensor 5 or the second sensor 6. As long as either the first sensor 5 or the second sensor 6 detects that a pet has entered the litter box 11, the first sensor 5 or the second sensor 6 will transmit this information to the main control board 100, which will then control the drive mechanism 3 to stop operating. At this time, the litter cleaning component 4 can be controlled to be in a stopped state to ensure that the litter cleaning component 4 will not continue to move and harm the pet. Only when neither the first sensor 5 nor the second sensor 6 detects a pet will the drive mechanism 3 continue to drive the litter cleaning component 4 to clean along the first direction X or reset along the opposite direction of the first direction X. This solution ensures the safety of pets when using the toilet and improves the user experience.

[0060] Please refer to them again. Figure 3 and Figure 4In this embodiment, the first sensor 5 is preferably fixed inside the housing 1 and located in the direction opposite to the stool collection chamber 2 of the stool cleaning assembly 4, and the second sensor 6 is preferably disposed on the side of the movable seat 41 facing the stool collection chamber 2. In other embodiments, the first sensor 5 and the second sensor 6 may both be fixed on the movable seat 41, or the first sensor 5 and the second sensor 6 may both be fixed inside the housing 1.

[0061] Please refer to the following: Figure 1 , Figures 3 to 5 In this embodiment, the compartment door 200 is designed to automatically cover the opening of the collection trough 21 under its own weight. A drive unit 201 protrudes from the compartment door 200. When the scooping component 42 continues to move along the guide groove 12 in the first direction X, the scooping component 42 will push the compartment door 200 upwards by squeezing the drive unit 201, thereby opening the opening of the collection trough 21. When the cleaning component 4 moves away from the collection chamber 2 in the opposite direction of the first direction X, the compartment door 200 will automatically fall down due to gravity and cover the collection trough 21 again.

[0062] Please refer to the following: Figures 1 to 3 and Figure 8 The housing 1 includes an outer shell 13 and a sand chamber 14 disposed inside the outer shell 13. The sand chamber 14 contains the aforementioned sand trough 11. The sand chamber 14 is detachable longitudinally relative to the outer shell 13. By designing a detachable sand chamber 14, users can remove the sand chamber 14 separately to clean the internal sand trough 11, thereby facilitating the cleaning of the sand trough 11. To achieve the detachable function of the sand chamber 14, this solution designs the shovel component 42 to be slidably connected to the side of the movable seat 41 facing the collection chamber 2. Furthermore, a vertically penetrating mounting and disassembly groove 131 is provided on the inner side wall of the outer shell 13. Specifically, when the cleaning component 4 is reset to its initial position in the opposite direction of the first direction X, the movable seat 41 is located outside the upward movement path of the sand chamber 14, so that the movable seat 41 will not interfere with the upward removal of the sand chamber 14. At the same time, the end of the shovel component 42 in the length direction (i.e., the second direction Y) is located below the mounting and disassembly groove 131. In other words, when the sand bin 14 needs to be disassembled, the entire cleaning assembly 4 needs to be moved to the initial position in the opposite direction of the first direction X. Then, the shovel part 42 is taken out upward along the mounting and disassembly groove 131. Only then can the sand bin 14 be easily taken out upward. During the upward removal process, the sand bin 14 will collide with the drive part 201 of the bin door 200 to drive the bin door 200 to automatically open upward. Of course, the bin door 200 can also be manually opened upward before removing the sand bin 14.

[0063] Please refer to the following: Figure 7 and Figure 9The litter trough 11 has racks 9 fixed on both sides in the second direction Y. The length direction of the racks 9 extends in the first direction X. The aforementioned movable seat 41 preferably achieves a sliding connection with the housing 1 in the first direction X by directly sliding with the racks 9 in the first direction X. The aforementioned drive mechanism 3 is preferably designed to be housed within the movable seat 41 to save space occupied by the drive mechanism 3, thereby helping to reduce the overall size of the pet litter box. The drive mechanism 3 preferably includes a motor 31, a drive gear 32, a transmission gear 33, a transmission rod 34, and a travel gear 35. The motor 31 is fixedly connected to the movable seat 41, the transmission rod 34 is rotatably connected to the movable seat 41, and both ends of the transmission rod 34 extend beyond the movable seat 41 along the second direction Y. The transmission gear 33 is sleeved and fixed on the transmission rod 34. The drive gear 32 is connected to the motor 31 and meshes with the transmission gear 33. The travel gear 35 is sleeved and fixed at both ends of the transmission rod 34 in the length direction (i.e., the second direction Y). The travel gear 35 meshes with a corresponding rack 9. When motor 31 drives the drive gear 32 to rotate, the drive gear 32 will drive the transmission gear 33 to rotate. Since the transmission gear 33 and the transmission rod 34 are fixedly connected, the transmission rod 34 will rotate with the transmission gear 33, thereby causing the traveling gear 35 at the end of the transmission rod 34 to roll relative to the rack 9. This achieves the purpose of enabling the entire cleaning assembly 4 to move along the first direction X. In fact, by controlling the forward and reverse rotation of motor 31, the entire cleaning assembly 4 can be controlled to move in the positive or negative direction of the first direction X. In other embodiments, the drive mechanism 3 can also be a lead screw module or a linear motor.

[0064] Please refer to the following: Figure 1 , Figure 3 and Figure 9 Considering that cats usually bury the litter box manually after using it, and that litter may fall onto the rack 9 during the process, causing severe wear on the rack 9 as the traveling gear 35 rolls on it, this embodiment addresses this issue by providing flexible dustproof strips 10 on both sides of the opening of the litter trough 11 along the second direction Y. The dustproof strips 10 are designed inside the rack 9 to separate it from the litter trough 11. The upper or lower end of the dustproof strip 10 is fixedly connected to the housing 1. The aforementioned transmission rod 34 extends from the dustproof strip 10 to the top or bottom of the rack 9, allowing the traveling gear 35 at the end of the transmission rod 34 to mesh with the rack 9. This design prevents litter from splashing onto the rack 9 without affecting the movement of the entire litter cleaning assembly 4 in the first direction X. In other embodiments, a bellows cover can be used to simultaneously cover both the rack 9 and the traveling gear 35.

These descriptions are only for explaining the principles of the present utility model and should not be construed as limiting the scope of protection of the present utility model in any way.
