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] Pet toilets, especially automatic litter boxes for domestic cats, have become an essential part of modern pet care. These devices typically use a filter scoop that moves and swings within the inner tank to automatically remove clumps of pet excrement and transport it to a collection box, thus greatly reducing the cleaning burden on owners.

[0003] Currently, pet toilets with automatic cleaning functions on the market typically integrate walking and swinging mechanisms to drive the filter shovel's movement. However, this design presents significant challenges for daily maintenance. First, the filter shovel, being the part that directly contacts waste, requires frequent and thorough cleaning to maintain hygiene. Its fixed installation makes it difficult for users to remove for cleaning, leading to hard-to-reach areas. Second, and more significantly, the inner container, as the container for cat litter, is the part with the most waste residue and requires the most frequent disassembly and cleaning. However, because the filter shovel and its driving mechanism are often located above or to the side of the inner container, they create an obstacle, blocking the path to remove the inner container. Users often need to perform a series of cumbersome disassembly steps, sometimes requiring tools, or even tilting or flipping the entire device significantly, which is inconvenient and risks damaging the delicate internal components. This process is particularly unfriendly to users with limited strength (such as women or the elderly).

[0004] Therefore, a long-standing and unresolved contradiction exists in existing technologies: the complex mechanical structure required for automation functions clashes sharply with users' urgent need for convenient cleaning and maintenance of core, easily soiled components (especially the filter shovel and inner liner). How to achieve rapid, tool-free disassembly of the filter shovel and inner liner without affecting the stability of the equipment's automatic operation has become a pressing technical problem in this field. Utility Model Content

[0005] 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.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0037] The traction belt is fitted over the outside of the first and second traction wheels;

[0038] The traction belt is connected to the moving plate. When the traction belt moves, it can drive the moving plate to move on one side of the side plate. The walking component moves along the moving plate on the side plate of the main body.

[0039] Furthermore, a protective cover is provided on the outside of the traction assembly. The protective cover is fixedly installed on the side plate, and the buckle plate is fastened to the edge of the protective cover, so that the fixedly installed protective cover provides longitudinal support for the moving plate.

[0040] Both the first roller and the buckle plate provide the necessary support force for the moving plate to be installed on the side plate. When the walking assembly is detached from the top of the moving plate, the buckle plate independently provides the necessary support force for the moving plate to be installed on the side plate.

[0041] Furthermore, the driving components include:

[0042] The second drive motor is mounted on the main body;

[0043] The drive gear is installed at the power output end of the second drive motor;

[0044] The driven gear meshes with the driving gear;

[0046] The end of the drive shaft is connected to the first traction wheel, and is suitable for transmitting rotational torque to the first traction wheel.

[0047] Furthermore, the locking component includes:

[0048] The mounting section is located on the movable plate;

[0049] The elastic element is installed on the mounting part;

[0050] The locking element has a connecting part at one end and a locking part at the other end, with the connecting part abutting against the elastic element;

[0051] Under the elastic force of the elastic element, the locking part can pass through the outer shell of the moving plate and extend into the locking hole of the mounting plate.

[0052] The actuating element is mounted on the movable plate. When the actuating element is pressed, it can trigger the locking element to retract, causing the locking part to be pulled out from the locking hole.

[0054] The end of the trigger away from the second inclined surface is provided with a pressing part. When the pressing part is subjected to force, the second inclined surface can squeeze the first inclined surface and slide relative to it, so that the locking part retracts relative to the mounting plate.

[0055] Furthermore, one of the housings of the mounting plate and the movable plate is provided with a sliding groove, and the other housing of the mounting plate and the movable plate is provided with a slider corresponding to the sliding groove. After the slider slides into the sliding groove, the walking component is detachably mounted on the housing of the movable plate via the mounting plate.

[0056] Furthermore, there are two movable plates, which are respectively set on the side plates on both sides of the main body, and the swing mechanism can be selectively installed on one or both movable plates.

[0057] Furthermore, the pet toilet also includes a clump collection box, which is detachably installed on one side of the main body.

[0058] Furthermore, multiple guardrails are installed on the top of the main body after being removed.

[0059] This application also provides a pet toilet, including:

[0065] A filter shovel, located in the inner cavity of the main body, includes a filter section and a connecting section detachably connected to the swing mechanism;

[0066] The movable plate is provided with a guide channel, which has a closed state and an open state:

[0067] In the closed state, the guide channel constrains the connecting portion of the filter shovel that passes through it, preventing it from detaching from the moving plate;

[0068] In the open state, the guide channel allows the connecting portion of the filter shovel to move out along the channel, thereby enabling selective removal of the filter shovel.

[0069] The state switching of the guide channel is achieved through an operable structure, allowing the user to selectively maintain the working position of the filter shovel or release its restriction as needed.

[0070] The operable structure includes a mounting plate spatially located above the outlet of the guide channel, the mounting plate being selectively removable and adapted to physically block the path of the connecting portion of the filter shovel being pulled upward from the guide channel.

[0071] The advantages of this pet toilet over existing technologies are as follows: By making the connection between the filter shovel and the swing mechanism detachable, users can easily remove the filter shovel from the main body cavity for thorough rinsing when cleaning is needed. This effectively solves the hygiene problem of bacteria growth and odor caused by the filter shovel's long-term contact with dirt. Simultaneously, this design also provides crucial operational space for disassembling the inner liner. With the filter shovel removed as a major obstacle, the inner liner can be vertically removed from the main body cavity without obstruction, making litter replacement and inner liner cleaning exceptionally convenient and greatly improving the user experience.

[0094] 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.

[0095] 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.

[0096] 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.

[0097] 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.

[0098] 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.

[0099] Furthermore, the walking mechanism 50 includes a walking component 501, a traction component 502, and a drive component 503;

[0100] 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 equipped with a frame 102, that is, a frame 102 is provided, and the frame 102 provides a track for the walking component 501.

[0101] 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.

[0102] 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.

[0103] 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.

[0104] 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.

[0105] In addition, the movable plate 30 has a buckle plate 301, and the second roller 5014 is rotatably mounted on the buckle plate 301. The side plate 101 is provided with a guide plate 103, and the second roller 5014 rolls in contact with the guide plate 103.

[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] The Pet Toilet 100 has three working modes: a sieving mode, a clumped foreign object collection mode, and a clumped foreign object transfer mode.

[0116] 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.

[0117] 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.

[0118] 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.

[0119] 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.

[0120] Furthermore, a sterilization lamp 200 is provided on the main body 10 or the movable plate 30. The sterilization lamp 200 can irradiate the inner cavity of the clumped foreign matter collection box 90, thereby disinfecting and sterilizing the collected clumped cat litter.

[0121] In some embodiments, refer to Figure 1 , Figure 16Multiple guardrails 300 are detachably installed on the top of the main body 10. The guardrails 300 can increase the enclosure height of the main body 10. Specifically, one guardrail 300 of this application is provided with an insert rib 310, and adjacent guardrails 300 are provided with an insert guide groove 320. When adjacent guardrails 300 are spliced, the insert rib 310 is inserted into the insert guide groove 320 of the adjacent guardrail 300. After all the guardrails 300 are spliced ​​into a whole, they can be fixed to the top of the main body 10 with bolts.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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:

[0126] S1. Reference Figure 18 Disassemble the entire guardrail 300 and then separate the individual guardrail units;

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] 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.

[0132] 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.

[0133] 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.

[0134] Thus, this application also provides a pet toilet, comprising:

[0135] Main body 10;

[0136] The inner liner 80 is detachably housed within the inner cavity of the main body 10;

[0137] The movable plate 30 is movably mounted on the side of the main body 10;

[0138] The walking mechanism 50 is disposed on the main body 10 and is used to drive the moving plate 30 to move along the main body 10;

[0139] The swing mechanism 40 is mounted on the movable plate 30 and is driven to move by the movable plate 30;

[0140] The filter shovel 20 is located in the inner cavity of the main body 10 and includes a filter part 202 and a connecting part 201 that is detachably connected to the swing mechanism 40.

[0141] 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 that passes 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.

[0142] 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.

[0143] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
