Description

Technical Field

[0001] This utility model relates to the field of animal excrement collection equipment, and in particular to a pet toilet. Background Technology

[0002] Currently, most pet toilets on the market with guardrail units typically have the guardrail units integrally molded with the main body or connected by a permanent fixing method.

[0003] While this fixed design is simple in structure, it brings many inconveniences to use. First, cleaning and maintenance are difficult: the inside of the guardrail unit and the connection points are very easy to get covered with cat litter or excrement brought out by pets, creating a dead spot for hygiene. The fixed structure makes it impossible for users to thoroughly clean it, which can easily breed bacteria over time and affect the pet's health.

[0004] Secondly, storage and transportation are inconvenient: the fixed guardrail units make the product bulky and irregular in shape, which not only occupies too much storage and home space, but also makes it more susceptible to damage during packaging and transportation.

[0005] In addition, the functionality lacks adaptability: fixed-height guardrails cannot be flexibly adjusted or removed for pets of different sizes and habits (for example, kittens may need low entry points, while adult cats that like to dig in the litter box need high guardrail units), making it difficult to meet the diverse needs of users. Utility Model Content

[0006] The purpose of at least one specific embodiment of this utility model is to overcome the defects of the existing technology and provide a pet toilet.

[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0008] A pet toilet includes a main body and a plurality of guardrail units disposed on the top of the main body, the guardrail units being detachably mounted on the top of the main body.

[0009] Furthermore, the guardrail unit includes an insert rib and an insert guide groove, and adjacent guardrail units are spliced ​​together by the cooperation of the insert rib and the insert guide groove.

[0010] Furthermore, after multiple guardrail units are spliced ​​together as a whole, they can be detachably installed on the top of the main body.

[0011] Furthermore, the guardrail unit is installed on the main body in one or more combinations of plug-in, snap-on, or bolt-fixed methods.

[0012] Furthermore, a movable plate is installed on the side of the main body, and a swing mechanism is installed on the movable plate. The swing mechanism is connected to the filter shovel. The movable plate can drive the filter shovel to move in the inner cavity of the main body, and the swing mechanism is adapted to drive the filter shovel to swing back and forth.

[0013] Furthermore, one side of the main body is equipped with a clump foreign object collection box, and after the multiple guardrail units are installed on the top of the main body, the side of them near the clump foreign object collection box forms an unobstructed opening.

[0014] The opening is configured to provide a channel for clumps of foreign matter to fall into the clumps collection box when the swing mechanism causes the filter shovel to swing to the tilting position.

[0015] Furthermore, an inner liner is placed inside the cavity of the main body, and a frame is provided on the top of the main body, which can be used to limit the inner liner.

[0016] Furthermore, the guardrail unit is detachably mounted on the frame.

[0017] Furthermore, the guardrail unit has a perforated section.

[0018] The advantages of the pet toilet provided by the above-mentioned technical solution compared with the prior art are as follows: the detachable guardrail unit structure enables modular packaging of the product, significantly reducing the overall packaging volume and lowering warehousing and logistics costs. At the same time, the flat packaging form also reduces the risk of damage during transportation and improves the commercial circulation of the product;

[0019] This design allows users to decide whether to install guardrail units based on their pet's behavior (such as whether they tend to splash sand) or different stages of growth. This modular configuration makes the product more adaptable to individual needs and enhances the user experience.

[0020] Another technical solution adopted in this application is: providing a pet toilet, including a main body, and further including:

[0021] Multiple guardrail units are installed at the top of the main body;

[0022] The guardrail unit is installed on the top of the main body, and the side of the guardrail unit is provided with an avoidance structure. The avoidance structure is configured to provide movement space for the walking mechanism set on the main body when the guardrail unit is installed on the main body, so as to avoid interference.

[0023] Furthermore, the avoidance structure is a hollow portion formed on the side of the guardrail unit.

[0024] Furthermore, the walking mechanism includes a walking component adapted to move along a predetermined track on the top of the main body, and the projection of the avoidance structure in the vertical direction at least partially covers the movement path of the walking component.

[0025] Furthermore, the top of the main body is provided with a frame, the walking component includes a roller that rolls in contact with the frame, and the position of the avoidance structure corresponds to the area traversed by the roller when it moves.

[0026] Another technical solution adopted in this application is: providing a pet toilet, comprising:

[0027] Main body, walking mechanism and guardrail unit;

[0028] The walking mechanism includes a walking component that moves on top of the main body;

[0029] The guardrail unit is located on the top of the main body;

[0030] The guardrail unit has a cutout on the side facing the walking component to allow the walking component to pass.

[0031] While fulfilling its basic function (preventing cat litter from splashing), the guardrail unit provides the necessary movement space for the key moving parts of the walking mechanism (such as the walking components and rollers), fundamentally eliminating the risk of physical interference between the two and ensuring the stable and reliable operation of the automatic cleaning function.

[0032] Another technical solution adopted in this application is: providing a pet toilet, including a main body;

[0033] The pet toilet is composed of multiple functional modules, which include at least a guardrail unit module, a filter shovel, and an inner liner.

[0034] The guardrail unit module, the filter shovel, and the inner liner are all installed on the main body in a way that allows for independent detachment.

[0035] Another technical solution adopted in this application is: providing a pet toilet, including a main body, with a plurality of guardrail units provided on the top of the main body, the guardrail units being detachably installed on the main body, thereby allowing all the guardrail units to be removed from the main body as a whole module.

[0036] Furthermore, adjacent guardrail units are interconnected by a detachable splicing structure.

[0037] Users can disassemble and clean individual guardrail modules, filter shovels, or inner tanks as needed, without having to deal with a large and complex whole. This "point-to-point" maintenance method is intuitive, simple, and labor-saving, greatly reducing the barrier to daily cleaning and maintenance.

[0038] This facilitates production, assembly, and after-sales maintenance, reducing lifecycle costs. The modular design allows each functional unit to be produced and tested independently before final assembly, improving production efficiency. If a module fails, only that specific module needs to be replaced. Attached Figure Description

[0061] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0062] Reference Figures 1 to 3 , Figure 8 , Figure 9 A pet toilet 100 includes a main body 10, a filter scoop 20 disposed in the inner cavity of the main body 10, a movable plate 30 disposed on the side plate 101 of the main body 10, a swinging mechanism 40 mounted on the movable plate 30 and capable of driving the filter scoop 20 to swing back and forth in the inner cavity of the main body 10, and a walking mechanism 50 disposed on the side of the main body 10 and capable of driving the movable plate 30 to move on the main body 10. When the pet toilet 100 is used as a cat litter box structure, the inner cavity of the main body 10 is filled with cat litter.

[0063] The filter shovel 20 includes a connecting part 201 and a filter part 202 disposed on the connecting part 201. The connecting part 201 is connected to the swing mechanism 40.

[0064] In this embodiment, there are two movable plates 30, which are respectively disposed on the side plates 101 on both sides of the main body 10. The swing mechanism 40 can be selectively installed on one or both movable plates 30.

[0065] Specifically, the swing mechanism 40 includes an arc-shaped rack 401 disposed on the side of the movable plate 30, a first gear 402 meshing with the arc-shaped rack 401, and a swing arm 403 hinged to the movable plate 30. One end of the swing arm 403 hinged to the movable plate 30 is fixedly connected to the connection part 201 of the filter shovel 20. The other end of the swing arm 403 is equipped with a first drive motor 404, which provides driving force to the first gear 402. After the first drive motor 404 starts, it can drive the first gear 402 to rotate forward. The first gear 402 can move forward along the trajectory of the arc-shaped rack 401. During the movement, the first gear 402... The swing arm 403 rotates forward on the moving plate 30, and the swing arm 403 drives the filter shovel 20 to swing forward in the inner cavity of the main body, forming a sand-shoveling action. After the sand-shoveling action is completed, the first drive motor 404 drives the first gear 402 to rotate in the opposite direction. The first gear 402 moves in the opposite direction along the trajectory of the arc rack 401. The first gear 402 drives the swing arm 403 to rotate in the opposite direction on the moving plate 30. At this time, the swing arm 403 drives the filter shovel 20 to swing in the opposite direction in the inner cavity of the main body, forming a reset action after sand shoveling. When the first drive motor 404 rotates in the forward and reverse directions alternately, the filter shovel 20 forms a sand-shoveling-reset action cycle in the inner cavity of the main body.

[0066] Furthermore, the walking mechanism 50 includes a walking component 501, a traction component 502, and a drive component 503;

[0067] The outer side of the movable plate 30 is equipped with a housing 30a. In this embodiment, the walking component 501 is detachably installed on the housing 30a and moves along the side plate 101 of the main body 10 with the movable plate 30. The top of the main body 10 is provided with a frame 102, which provides a track for the walking component 501.

[0068] It is understandable that the frame 102 and the inner liner 80 can be either separate or integrally formed. In particular, when the inner liner 80 is made of a flexible material, such as silicone, the frame 102 can be used to fix the inner liner 80 separately; or, when the inner liner 80 is made of a rigid material, such as stainless steel, the frame 102 can be integrally formed with the inner liner 80.

[0069] The traction component 502 uses the main body 10 as the mounting carrier to provide traction force to the walking component 501; the drive component 503 uses the main body 10 as the mounting carrier to provide drive force to the traction component 502.

[0070] The traction component 502 is located in the area below the movable plate 30. After the main body 10 is placed horizontally on the ground, when viewed from above, the movable area of ​​the movable plate 30 and the attached outer shell 30a on the side plate 101 can cover the projection area of ​​the traction component 502. With this design, the traction component 502 can make good use of the space below the movable plate 30 without increasing the floor space of the pet toilet 100.

[0071] Furthermore, refer to Figures 4 to 12 The walking assembly 501 includes a mounting plate 5011, a support plate 5012, a first roller 5013, and a second roller 5014. The mounting plate 5011 is mounted on the top of the moving plate 30 via a locking assembly 504. The support plate 5012 is connected to the mounting plate 5011. The first roller 5013 is rotatably mounted on the support plate 5012 and rolls against the frame 102. The first roller 5013 provides the moving plate 30 with the required support force for mounting on the side plate 101.

[0072] In addition, the movable plate 30 has a buckle plate 301, the second roller 5014 is rotatably mounted on the buckle plate 301, and the side plate 101 is provided with a guide plate 103, and the second roller 5014 is in rolling contact with the guide plate 103.

[0073] Furthermore, the traction assembly 502 includes a first traction wheel 5021, a second traction wheel 5022, a traction belt 5023, and a protective cover 5024. The first traction wheel 5021 and the second traction wheel 5022 are rotatably mounted on the side plate 101. The traction belt 5023 is sleeved on the outside of the first traction wheel 5021 and the second traction wheel 5022. The traction belt 5023 is fixedly connected to the moving plate 30. In addition, the protective cover 5024 is fixedly mounted on the side plate 101 by bolts. The buckle plate 301 is fastened to the edge of the protective cover 5024, so that the fixedly mounted protective cover 5024 provides longitudinal support for the moving plate 30.

[0074] Both the first roller 5013 and the buckle plate 301 provide the necessary support force to the movable plate 30 for mounting on the side plate 101. When the walking assembly 501 is detached from the top of the movable plate 30, the buckle plate 301 independently provides the necessary support force to the movable plate 30 for mounting on the side plate 101.

[0075] In this embodiment, the outer sides of the first traction wheel 5021 and the second traction wheel 5022 are equipped with external teeth, and the inner side of the traction belt 5023 is equipped with internal teeth that mesh with the first traction wheel 5021 and the second traction wheel 5022, ensuring the stability of the cooperation between the first traction wheel 5021, the second traction wheel 5022 and the traction belt 5023. When the traction belt 5023 moves, it can drive the moving plate 30 to move on the side plate 101. During the movement of the moving plate 30, the first roller 5013 of the walking assembly 501 rolls on the frame 102, and the second roller 5014 rolls on the bottom surface of the guide plate 103, ensuring the continuity of the movement of the moving plate 30 on the side plate 101. During the movement of the moving plate 30, it drives the swing mechanism 40 and the filter shovel 20 to move together. During the movement of the filter shovel 20, the swing mechanism 40 drives the filter shovel 20 to swing back and forth, screening the clumped cat litter in the main body 10.

[0076] Furthermore, the drive assembly 503 includes a second drive motor 5031, a driving gear 5032, a driven gear 5033, and a transmission shaft 5034; wherein, the second drive motor 5031 is mounted on the main body 10, the driving gear 5032 is mounted on the power output end of the second drive motor 5031, the driven gear 5033 meshes with the driving gear 5032, the transmission shaft 5034 is rotatably mounted on the main body 10 and connected to the driven gear 5033, and the end of the transmission shaft 5034 is connected to the first traction wheel 5021, and the second drive motor 5031 is open. After starting, the drive shaft 5034 transmits rotational torque to the first traction wheel 5021. The first traction wheel 5021 drives the traction belt 5023 to run. The traction belt 5023 drives the entire moving plate 30 to move on the side plate 101. During the movement, the first roller 5013 rolls on the frame 102, and the second roller 5014 rolls on the bottom surface of the guide plate 103. The first roller 5013 and the second roller 5014 form two stable walking tracks, ensuring that the moving plate 30 and the filter shovel 20 on the moving plate 30 are in a stable walking posture.

[0077] Furthermore, refer to Figure 13 The locking assembly 504 includes a mounting portion 5041 disposed on the movable plate 30, an elastic member 5042 disposed on the mounting portion 5041, a locking member 5043, and an actuating member 5044. The actuating member 5044 is mounted on the movable plate 30. The elastic member 5042 is preferably a spring. One end of the locking member 5043 is a connecting portion 5045, and the other end is a locking portion 5046. The connecting portion 5045 abuts against the elastic member 5042. The mounting plate 5011 has a locking hole 5047. Under the elastic force of the elastic member 5042, the locking portion 5046 can pass through the outer shell 30a of the movable plate 30 and extend into the locking hole 5047 of the mounting plate 5011. The mounting plate 5011 is in a locked state on the outer shell 30a of the movable plate 30.

[0078] Furthermore, the locking member 5043 is provided with a socket 5048, the socket 5048 is provided with a first inclined surface 5049, one end of the actuating member 5044 is provided with a second inclined surface 5040, the end of the actuating member 5044 extends into the socket 5048, and the first inclined surface 5049 and the second inclined surface 5040 are in contact and engaged.

[0079] The actuating member 5044 has a pressing part 504a at one end away from the second inclined surface 5040. When the pressing part 504a is subjected to force, the second inclined surface 5040 can press the first inclined surface 5049 and slide relative to it, so that the locking member 5043 retracts relative to the mounting plate 5011, the locking part 5046 is pulled out from the locking hole 5047, and the locking state of the mounting plate 5011 on the moving plate 30 is released.

[0080] Furthermore, refer to Figure 14 One of the housings 30a of the mounting plate 5011 and the movable plate 30 is provided with a groove 60, and the other of the housings 30a of the mounting plate 5011 and the movable plate 30 is provided with a slider 70 corresponding to the groove 60. The slider 70 slides with the groove 60 to play a role in installation and positioning. In this embodiment, the top of the housing 30a of the movable plate 30 is provided with a groove 60. When the mounting plate 5011 is installed on the housing 30a, the mounting plate 5011 slides on the top of the housing 30a, so that the slider 70 is engaged with the groove 60. After the movement is in place, the locking hole 5047 is aligned with the locking part 5046. Under the elastic force of the elastic member 5042, the locking part 5046 passes through the moving plate 30 and extends into the locking hole 5047 of the mounting plate 5011. At this time, the mounting plate 5011 is locked on the top of the outer shell 30a. After the mounting plate 5011 is installed, it is equivalent to the walking component 501 being successfully installed on the side plate 101. At this time, the assembly state is that the first roller 5013 is supported on the top of the frame 102, and the second roller 5014 is supported on the bottom of the guide plate 103.

[0081] In some embodiments, an inner liner 80 is detachably installed in the inner cavity of the main body 10, and the inner liner 80 includes a horizontal section 801 and an arc-shaped section 802.

[0082] The Pet Toilet 100 has three working modes: a sieving mode, a clumped foreign object collection mode, and a clumped foreign object transfer mode.

[0083] When in screening mode, the travel of filter shovel 20 is located in the horizontal section 801 of the inner liner 80. When the walking mechanism 50 drives the filter shovel 20 to travel in the inner cavity of the main body 10, the swing mechanism 40 drives the filter shovel 20 to swing back and forth (the filter shovel 20 is in a sand-resetting action cycle). The filter part 202 of the filter shovel 20 intermittently contacts the horizontal section 801, and the filter shovel 20 screens the clumps of foreign matter (clumps of cat litter containing animal feces) in the main body 10.

[0084] When in the clumped foreign object collection mode, the travel of the filter shovel 20 is located in the arc-shaped section 802 of the inner liner 80. At this time, the walking mechanism 50 drives the filter shovel 20 to continue to move, and the swing mechanism 40 keeps the filter shovel 20 rotated to the collection posture position and drives the filter shovel 20 to swing in one direction. The filter part 202 of the filter shovel 20 continuously contacts the arc-shaped section 802 until the filter shovel 20 collects the clumped foreign objects in the main body 10. The collected clumped foreign objects are concentrated on the filter part 202.

[0085] When in the working mode of transferring clumped foreign objects, the walking mechanism 50 drives the filter shovel 20 to reset to the initial position. During the reset process, the swing mechanism 50 does not work. After the filter shovel 20 is reset to the initial position, the swing mechanism 50 drives the filter shovel 20 to flip over, and pours the clumped foreign objects collected by the filter shovel 20 into the clumped foreign object collection box 90.

[0086] Furthermore, refer to Figure 1 , Figure 2 , Figure 15 The clumped foreign object collection box 90 is detachably installed on one side of the main body 10. The clumped foreign object collection box 90 has a cover plate 901. Specifically, one side of the clumped foreign object collection box 90 has a hanging plate 902. The clumped foreign object collection box 90 is fastened to one side of the main body 10 by the hanging plate 902. In this embodiment, one side of the clumped foreign object collection box 90 has a recessed mounting opening 903. After the clumped foreign object collection box 90 is installed on one side of the main body 10, the recessed mounting opening 903 can cover the outside of the drive component 503, thus protecting the drive component 503.

[0087] Furthermore, the main body 10 or the movable plate 30 is equipped with a sterilization lamp 200, which can irradiate the inner cavity of the clumped foreign matter collection box 90, thereby disinfecting and sterilizing the collected clumped cat litter.

[0088] In some embodiments, refer to Figure 1 , Figure 16Multiple guardrail units 300 are detachably installed on the top of the main body 10. The guardrail units 300 can increase the enclosure height of the main body 10. Adjacent guardrail units 300 are connected to each other through a detachable splicing structure. Specifically, one guardrail unit 300 of this application is provided with an insert rib 310, and adjacent guardrail units 300 are provided with an insert guide groove 320. The insert rib 310 and the insert guide groove 320 form a splicing structure. When adjacent guardrail units 300 are spliced, the insert rib 310 is inserted into the insert guide groove 320 of the adjacent guardrail unit 300. After all the guardrail units 300 are spliced ​​into a whole, they can be fixed to the top of the main body 10 with bolts.

[0089] It should be noted that in this embodiment, the guardrail unit 300 is detachably installed on the frame 102, and the guardrail unit 300 is installed by one or more of the following methods: plug-in type, snap-on type, or bolt fixing type.

[0090] Reference Figure 2 , Figure 6 After the guardrail unit 300 is installed on the top of the main body 10, its side near the clump foreign object collection box 90 forms an unobstructed opening; this opening is configured to provide a channel for clump foreign objects to fall into the clump foreign object collection box 90 when the swing mechanism drives the filter shovel 20 to swing to the tilting position. In addition, the guardrail unit 300 has a cutout portion 330.

[0091] The detachable guardrail unit structure enables modular packaging of products, significantly reducing overall packaging volume and lowering warehousing and logistics costs. At the same time, the flat packaging format reduces the risk of damage during transportation and improves the product's commercial viability.

[0092] This design allows users to decide whether to install the guardrail unit 300 based on their pet's behavior (such as whether it tends to splash sand) or different growth stages. This modular configuration makes the product more suitable for personalized needs and enhances the user experience.

[0093] The guardrail unit 300 is installed on the top of the main body 10, and the side of the guardrail unit 300 is provided with an avoidance structure. The avoidance structure is configured to provide movement space for the walking mechanism 50 set on the main body 10 when the guardrail unit 300 is installed on the main body 10, so as to avoid interference. Specifically, the avoidance structure is a hollow part 330 formed on the side of the guardrail unit 300. The projection of the avoidance structure (hollow part 330) in the vertical direction at least partially covers the movement path of the walking component 501.

[0094] Since the walking assembly 501 includes a first roller 5013 that rolls into contact with the frame 102, the position of the avoidance structure (cutout 330) corresponds to the area that the first roller 5013 passes through when it moves.

[0095] In summary, the mounting plate 5011 and the first roller 5013 in the walking assembly 501 move on the frame 102 at the top of the main body. By designing the cutout portion 330, the necessary movement space is provided for the key moving parts of the walking mechanism 50 (such as the walking assembly 501 and the first roller 5013), allowing the walking assembly 501 to complete its reciprocating walking task along the frame 102 without obstruction, thus ensuring the normal operation of the entire automated manure screening function.

[0096] Furthermore, the pet toilet of this application consists of multiple functional modules, which include at least a guardrail unit 300, a filter shovel 20, and an inner liner 80.

[0097] The guardrail unit 300, filter shovel 20 and inner liner 80 are all installed on the main body in a detachable manner. Multiple guardrail units 300 are provided on the top of the main body 10. The guardrail units 300 are installed on the main body 10 in a detachable manner, thereby allowing all guardrail units 300 to be removed from the main body as a whole module.

[0098] Users can disassemble and clean the guardrail unit 300, filter shovel 20, or inner liner 80 individually as needed, without having to deal with a large and complex whole. This "point-to-point" maintenance method is intuitive, simple, and labor-saving, greatly reducing the threshold for daily cleaning and maintenance.

[0099] This facilitates production, assembly, and after-sales maintenance, reducing lifecycle costs. The modular design allows each functional unit to be produced and tested independently before final assembly, improving production efficiency. If a module fails, only that specific module needs to be replaced.

[0100] Furthermore, the walking mechanism 50 of this application can drive the filter shovel 20 to move stably in the inner cavity of the main body 10, thereby improving the screening and collection efficiency of clumped cat litter.

[0101] The filter shovel 20, moving plate 30, swing mechanism 40, walking mechanism 50 and inner tank 80 provided in this application can all be disassembled from the main body 10 for easy assembly. In particular, the filter shovel 20 and inner tank 80 are easy to disassemble for cleaning.

[0102] Since the inner liner 80 contains cat litter, cat feces can easily soak into the litter and seep to the bottom of the inner liner 80. Therefore, the inner liner 80 needs to be disassembled frequently to replace the contaminated cat litter and clean the inner liner 80. In addition, the filter shovel 20 is also prone to getting contaminated with animal feces when sifting clumped cat litter, so the filter shovel 20 also needs to be disassembled and cleaned. The disassembly process of the inner liner 80 and the filter shovel 20 is explained in detail below with specific disassembly steps.

[0103] Reference Figure 2 After the various components of this application are assembled, when each component needs to be disassembled, the specific steps are as follows:

[0104] S1. Reference Figure 18 Disassemble the entire guardrail unit 300, and then separate the individual guardrail units;

[0105] S2. Reference Figure 13 , Figure 19 Disassemble the walking assembly 501, press the pressing part 504a of the trigger 5044 by hand, the locking part 5043 retracts relative to the mounting plate 5011, the locking part 5046 is pulled out from the locking hole 5047, the locking state of the mounting plate 5011 on the moving plate 30 is released, after sliding the mounting plate 5011, the slider 70 separates from the slide groove 60, the sliding mounting plate 5011 and the first roller 5013 are removed from the top of the outer shell 30a of the moving plate 30. It should be noted that since the buckle plate 301 on the moving plate 30 is fastened to the edge of the protective cover 5024, the fixedly installed protective cover 5024 provides longitudinal support for the moving plate 30, and the moving plate 30 will not fall off the main body 10 after the first roller 5013 is removed.

[0106] S3. Reference Figure 17 , Figure 20 When disassembling the filter shovel 20, since the moving plate 30 has a guide channel, which can be specifically implemented as an inclined groove 302, when disassembling the filter shovel 20, the connecting part 201 of the filter shovel 20 is pulled out from the inclined groove 302, and the connecting part 201 is separated from the swing arm 403, so the filter shovel 20 can be disassembled.

[0107] S4. Reference Figure 21 Remove the top frame 102 of the main body 10. The frame 102 and the inner liner 80 can be removed from the main body 10 together. Alternatively, the frame 102 and the inner liner 80 can be removed separately in steps.

[0108] Therefore, after the walking assembly 501 is removed from the outer shell 30a, the filter shovel 20 can be separated from the swing mechanism 40 and removed from the main body 10. After the filter shovel 20 is removed, the frame 102 can be removed from the main body 10. After the frame 102 is removed, the inner liner 80 can be separated from the main body 10 together with the frame 102 or removed separately.

[0109] The detachable filter scoop 20 and inner liner 80 are easy to clean. Moreover, when changing the cat litter, the inner liner 80 and the filled cat litter can be removed together without having to overturn the entire litter box structure, making it suitable for home-based female owners, convenient and labor-saving.

[0110] When disassembling the walking assembly 501, simply press the pressing part 504a of the trigger 5044 and slide the mounting plate 5011. After disassembling the walking assembly 501, the connecting part 201 of the filter shovel 20 can be pulled out from the inclined groove 302 to complete the disassembly of the filter shovel 20. After the filter shovel 20 is disassembled, the frame 102 can be directly removed from the main body 10, and the inner liner 80 can be removed from the main body 10, or the frame 102 and the inner liner 80 can be removed from the main body 10 together. The disassembly of the walking assembly 501, the filter shovel 20, and the inner liner 80 is very convenient and does not require complicated operations. Moreover, after the walking assembly 501, the filter shovel 20, and the inner liner 80 are disassembled, the moving plate 30 is fastened to the edge of the protective cover 5024 by the buckle 301 on it, and the stable installation state of the moving plate 30 will not be affected. The traction assembly 502 and the drive assembly 503 are both stably installed on the main body 10 without being affected.

[0111] Therefore, referring to Figure 14 , Figure 17 , Figure 19 and Figure 20 As shown, after the mounting plate 5011 is installed in place, it is spatially located above the outlet of the guide channel (sloping groove 302). Therefore, the presence of the mounting plate 5011 physically blocks the path of the filter shovel connection 201 as it is pulled upward from the sloping groove 302. Removing the mounting plate 5011 is the first step in releasing the spatial restriction on the filter shovel.

[0112] Specifically, the movable plate 30 is provided with a guide channel (corresponding to the inclined groove 302 described in the specification). The guide channel is configured to have two working states: in the closed state, it forms a motion constraint on the connecting part 201 of the filter shovel 20 passing through it, restricting its displacement in the unintended direction, thereby ensuring that the filter shovel 20 maintains a stable connection with the movable plate 30 and the swing mechanism 40 during operation; in the open state, the guide channel forms a channel that allows the connecting part 201 to move out along a specific path, so that the filter shovel 20 can be selectively and conveniently removed from the inner cavity of the main body 10.

[0113] The state switching of the guide channel is achieved through an operable structure, allowing the user to flexibly choose to lock the filter shovel 20 in the working position or release its limit according to maintenance or cleaning needs. In a preferred embodiment, the operable structure includes a mounting plate 5011 (part of the walking assembly 501) spatially located above the outlet of the guide channel. This mounting plate 5011 can be selectively installed or removed via a locking assembly 504. When the mounting plate 5011 is in place, it physically blocks the path of the connecting portion 201 of the filter shovel 20 as it is pulled upwards from the guide channel, thus closing the guide channel. When the mounting plate 5011 is removed, the upward movement path of the connecting portion 201 is released, the guide channel opens, and the filter shovel 20 can then be moved out along the channel.
