Description

TECHNICAL FIELD

[0001] The present application relates to the field of excrement collection equipment for animals, in particular to a pet toilet. BACKGROUND

[0002] Automatic cleaning pet toilets, especially intelligent cat litter boxes, have become an important device for improving pet convenience and home hygiene. Its core function relies on a set of precise walking mechanisms that drive the filter shovel to move and swing in the cat litter inner container to complete the screening, collection and removal of clumped foreign matter.

[0003] In the prior art, the mechanism for realizing the walking of the filter shovel usually includes a driving assembly, a traction assembly (such as a belt, a gear transmission system) and a walking assembly.

[0113] The walking mechanism 50 of the present application can drive the filter shovel 20 to stably walk in the inner cavity of the main body 10, thereby improving the screening and collecting efficiency of the clumped cat litter.

[0114] The filter shovel 20, the moving plate 30, the swing mechanism 40, the walking mechanism 50 and the inner container 80 provided by the present application can be detached from the main body 10, which is convenient for assembly, especially the filter shovel 20 and the inner container 80, which are convenient for disassembly and cleaning.

[0115] Since the inner container 80 stores cat litter, cat feces can easily soak the cat litter and penetrate to the bottom of the inner container 80, so the inner container 80 needs to be frequently disassembled, the contaminated cat litter inside is replaced, and the inner container 80 is cleaned, and the filtering shovel 20 is also easily contaminated with animal feces when screening the clumped cat litter, so the filtering shovel 20 also needs to be disassembled and cleaned. The disassembly process of the inner container 80 and the filtering shovel 20 will be described in detail below in combination with specific disassembly steps.

[0116] Referring to Figure 2 , when each component of the present application is assembled and needs to be disassembled, the specific steps are as follows:

[0117] S1. Referring to Figure 18 , disassemble the overall guardrail 300, and then separate each guardrail unit;

[0118] S2. Referring to Figure 13 , Figure 19 , disassemble the walking assembly 501, manually press the pressing part 504a of the touch part 5044, the locking part 5043 is retracted relative to the mounting plate 5011, the locking part 5046 is extracted from the locking hole 5047, the locking state of the mounting plate 5011 on the moving plate 30 is released, the sliding mounting plate 5011 is slid, the sliding block 70 is separated from the sliding groove 60, and the sliding mounting plate 5011 and the first roller 5013 are removed from the top of the shell 30a of the moving plate 30. It needs to be noted that since the buckle plate 301 on the moving plate 30 is buckled with the edge of the protective cover 5024, the fixedly installed protective cover 5024 supports the moving plate 30 longitudinally, and the moving plate 30 will not fall off the main body 10 after the first roller 5013 is removed;

[0119] S3. Referring to Figure 17 , Figure 20 , disassemble the filtering shovel 20, since the moving plate 30 has the inclined groove 302, when the filtering shovel 20 is disassembled, the connecting part 201 of the filtering shovel 20 is extracted from the inclined groove 302, and the connecting part 201 is separated from the swing arm 403, so that the filtering shovel 20 can be disassembled;

[0120] S4. Referring to Figure 21 , disassemble the frame 102 at the top of the main body 10, and the frame 102 is taken out from the main body 10 together with the inner container 80. Of course, the frame 102 and the inner container 80 can also be taken out separately in steps.

[0121] Therefore, after the walking assembly 501 is disassembled from the shell 30a, the filtering shovel 20 can be separated from the swing mechanism 40 and disassembled from the main body 10, after the filtering shovel 20 is disassembled, the frame 102 can be disassembled from the main body 10, and after the frame 102 is disassembled, the inner container 80 can be separated from the main body 10 together with the frame 102 or be independently separated and taken out.

[0122] The disassembled filter shovel 20 and the inner container 80 are convenient to clean, and when the cat litter is replaced, the inner container 80 and the filled cat litter can be taken out together, without overturning the entire cat litter basin structure, which is suitable for female users at home and is convenient and labor-saving.

[0123] When the walking assembly 501 is disassembled, a person presses the pressing part 504a of the touch piece 5044 and slides the mounting plate 5011, and after the walking assembly 501 is disassembled, the connecting part 201 of the filter shovel 20 is pulled out from the chute 302, and the disassembly of the filter shovel 20 is completed. After the filter shovel 20 is disassembled, the frame 102 can be directly taken off from the main body 10, the inner container 80 can be taken out from the main body 10, or the frame 102 and the inner container 80 can be taken out from the main body 10 together. The walking assembly 501, the filter shovel 20 and the inner container 80 are all convenient to disassemble and do not need complicated operation; moreover, after the walking assembly 501, the filter shovel 20 and the inner container 80 are disassembled, the moving plate 30 is buckled with the edge of the protective cover 5024 through the buckle plate 301 thereon, and the stable installation state of the moving plate 30 is not affected, and the traction assembly 502 and the driving assembly 503 are stably installed on the main body 10 and are not affected.

[0124] As can be seen from FIGS. Figure 14 、 Figure 17 、 Figure 19 and Figure 20 , after the mounting plate 5011 is installed in place, it is located above the outlet of the guide channel (the chute 302) in space, and therefore, the existence of the mounting plate 5011 physically blocks the path of the filter shovel connecting part 201 pulled out upward from the chute 302. Disassembling the mounting plate 5011 is the first step to release the space limitation of the filter shovel.

[0125] Specifically, the moving plate 30 is provided with a guide channel (corresponding to the chute 302 described in the specification), which is configured to have two working states: in the closed state, it forms a movement constraint to the connecting part 201 of the filter shovel 20 penetrating through it, limiting its displacement in the unintended direction, thereby ensuring that the filter shovel 20 maintains a stable connection relationship with the moving plate 30 and the swing mechanism 40 during the working process; in the open state, the guide channel forms a channel allowing the connecting part 201 to move out along a specific path, so that the filter shovel 20 can be selectively and conveniently taken out from the inner cavity of the main body 10.

[0126] The state switching of the guide channel is realized by an operable structure, which enables the user to flexibly select to lock the filter shovel 20 in the working position or release the position limitation according to the maintenance or cleaning needs. As a preferred embodiment, the operable structure includes a mounting plate 5011 (belonging to the walking assembly 501) which is spatially located above the outlet of the guide channel, and the mounting plate 5011 can be selectively mounted or removed by a locking assembly 504. When the mounting plate 5011 is in place, it physically blocks the path of the connecting part 201 of the filter shovel 20 from being pulled out upwardly from the guide channel, so that the guide channel is in the closed state; when the mounting plate 5011 is removed, the upward moving path of the connecting part 201 is released, and the guide channel is converted to the open state, at which time the filter shovel 20 can be moved out along the channel.

[0127] Finally, it should be noted that: the above examples are only used to illustrate the technical solutions of the present application, and not to limit it; although the present application has been described in detail with reference to the foregoing examples, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing examples, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solutions of the embodiments of the present application.
