[0030] In order to make the purpose, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] Here, it should be noted that in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution of the present invention are shown in the drawings, while other details less relevant to the present invention are omitted.

[0032] In addition, it should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0033] Please refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 7 As shown, the present invention discloses a litter box 100, which includes a basin body 10, a side cover 20 mounted on the basin body 10, a basin cover 30 and a driving mechanism 40.

[0034] Please refer to Figure 2 、 Figure 3 and Figure 4 As shown, the basin body 10 includes a housing 11, an excretion module 12, a packing module 13, a filter plate 14 and a storage box 15. The housing 11 includes a plurality of side walls 111. The plurality of side walls 111 enclose to form a receiving cavity 112 for receiving the excretion module 12, the packing module 13 and the filter plate 14. A storage groove 113 is further provided at the bottom of the housing 11 for receiving the storage box 15. The excretion module 12 is disposed below the basin cover 30 and is used for a cat to excrete. The excretion module 12 includes a sand box 121, a grooming rake 122 and a first driving assembly 123. The sand box 121 is used for storing cat litter so that a cat can excrete here. The grooming rake 122 is used to clean the excrement buried in the cat litter to the packing module 13. The grooming rake 122 can be various structures with gaps larger than the cat litter but smaller than the cat excrement, such as a plurality of parallel straight rods arranged side by side, a mesh structure with a grid design, and so on.

[0035] Please refer to Figure 5As shown, the first driving assembly 123 includes a slide rail 1231, a sliding module 1232 sliding along the slide rail 1231, a first driving arm 1233 mounted on the sliding module 1232, and a crank 1234 pivotally mounted on the basin body 10. A guiding groove 12311 is provided on the slide rail 1231. The distance between the guiding groove 12311 and the bottom wall of the housing 11 gradually increases from the end of the guiding groove 12311 away from the filter plate 14 to the end close to the filter plate 14. The driving slider 1232 moves along the guiding groove 12311. One end of the first driving arm 1233 is mounted on the driving slider 1232, and the other end is mounted on the grooming rake 122. The crank 1234 is pivotally mounted on the basin body 10 and includes a first arm (not shown) cooperating with the driving slider 1232 and a second arm 12341 cooperating with the filter plate 14. When the driving slider 1232 slides along the guiding groove 12311, the first driving arm 1233 drives the grooming rake 122 to move under the action of the driving slider 1232, thereby realizing the cleaning of the cat litter. Since the distance between the guiding groove 12311 and the bottom wall of the housing 11 gradually increases from the end of the guiding groove 12311 away from the filter plate 14 to the end close to the filter plate 14, when the grooming rake 122 moves from the end away from the filter plate 14 to the end close to the filter plate 14, the grooming rake 122 continuously rises, so as to clean the excrement in the litter box 121.

[0036] Please refer to Figure 2 and Figure 3 As shown, the filter plate 14 is pivotally mounted on the basin body 10, and the packing module 13 is arranged below the filter plate 14 and communicated with the storage box 15. When the driving slider 1232 abuts against the first arm, the crank 1234 rotates, so that the second arm 12341 abuts against the filter plate 14, and further the filter plate 14 is opened, facilitating the grooming rake 122 to clean the excrement into the packing module 13. The packing module 13 packs the excrement into a packing bag, and then the packed packing bag falls into the storage box 15 under the action of gravity for the user to take away and throw away.

[0037] Please refer to Figure 1 and Figure 2As shown, the side cover 20 is pivotally installed on one side of the basin body 10, and the basin cover 30 is pivotally installed on the other side of the basin body 10. Preferably, the side cover 20 is transparent. In this way, it is convenient for users to observe the situation inside the litter box 100. A channel 31 is formed between the side cover 20 and the basin cover 30, so that the cat can enter the excretion module 12 through the channel 31. Since the filter plate 14 is located above the packing module 13, after the cat excretes, the cat needs to pass through the channel 31 to get out of the litter box 100, so that the cat litter, excrement, etc. sticking to the cat's claws can leak into the packing module 13 through the filter plate 14, thereby avoiding polluting the environment around the litter box 100.

[0038] Please refer to Figure 7 , Figure 8 , Figure 6 and Figure 4 As shown, the driving mechanism 40 includes a first connecting rod 41 and a second connecting rod 42. One end of the first connecting rod 41 is pivotally installed on the side cover 20, and the other end is pivotally installed on the second connecting rod 42. The end of the second connecting rod 42 away from the first connecting rod 41 is directly or indirectly installed on the basin body 10. When the basin cover 30 is opened, the basin cover 30 directly or indirectly drives the second connecting rod 42 to rotate, and the second connecting rod 42 drives the first connecting rod 41 to rotate, and then the side cover 20 is opened through the first connecting rod 41. In this way, when the user opens the basin cover 30, the side cover 20 can be automatically opened, and then the internal structure of the litter box 100 can be exposed, which is convenient for users to clean, replace, repair, etc.

[0039] Furthermore, the driving mechanism 40 is further provided with a second driving component 43. The second driving component 43 includes a second driving arm 431. When the basin cover 30 is rotated, the basin cover 30 drives the second driving arm 431 to rotate, and the second driving arm 431 drives the second connecting rod 42 to rotate.

[0040] Preferably, please refer to Figure 11 As shown, the second driving arm 431 is provided with a driving post 4311. The second connecting rod 42 is provided with a relief groove 421 that cooperates with the driving post 4311.

[0041] Please refer to Figure 9As shown, the give-way slot 421 has a first position 4211 and a second position 4212, and the first position 4211 and the second position 4212 are respectively located at the two ends of the give-way slot 421. When the basin cover 30 is rotated, the basin cover 30 drives the second driving arm 431 to rotate, and the driving column 4311 moves from the first position 4211 along the give-way slot 421, and the side cover 20 does not move at this time. When the driving column 4311 moves to the second position 4212, the driving column 4311 abuts against the second connecting rod 42, so that the second connecting rod 42 rotates with the second driving arm 431. With such a configuration, the basin cover 30 can be rotated by a first angle first, and then the side cover 20 can be driven to rotate by a second angle together. In this way, the problem of inconsistent angles required to rotate the side cover 20 and the basin cover 30 can be effectively solved.

[0042] Furthermore, the cat litter box 100 is provided with a first buffer and a second buffer, and the first buffer and the second buffer are configured to store force to slow down the closing or opening speed of the basin cover 30 when the basin cover 30 is closed or opened.

[0043] Specifically, the first buffer member can be a first torsion spring 432, and the first torsion spring 432 is arranged in the second drive assembly 43. One end of the torsion spring 432 is fixed to the second drive assembly 43, and the other end is directly or indirectly fixed to the basin body 10. When the basin cover 30 is closed, the first torsion spring 432 is in the process of accumulating force. In this way, when the basin cover 30 is closed, a buffer force can be generated to prevent the basin cover 30 from being damaged due to the basin cover 30 being closed too hard. Preferably, the second drive assembly 43 is also provided with a bearing 433. The bearing 433 is fixedly mounted on the shell of the basin body 10. The other end of the first torsion spring 432 is fixed to the bearing 433. Of course, it can be understood that in other embodiments, the bearing 433 may not be provided, and the other end of the first torsion spring 432 is directly fixed to the shell of the basin body 10.

[0044] Further, the second driving assembly 43 is further provided with a driving shaft 434. The driving shaft 434 and the second driving arm 431 are fixed together to rotate synchronously. The driving shaft 434 includes a pivot shaft 4341 and a shaft cover 4342 located at one end of the pivot shaft 4341. The second connecting rod 42 is provided with a through groove 422. The pivot shaft 4341 passes through the through groove 422. The first torsion spring 432 is located between the shaft cover 4342 and the second driving arm 431. Preferably, the basin cover 30 is provided with a first driving portion (not shown), and the pivot shaft 4341 is provided with a second driving portion 4343 that cooperates with the first driving portion. One of the first driving portion and the second driving portion 4343 is an asymmetric groove, and the other is a cylinder that cooperates with the groove. With such a setting, the rotational movement of the basin cover 30 can be transmitted to the pivot shaft 4341 through the cooperation of the first driving portion and the second driving portion 4343, so that the pivot shaft 4341 rotates following the basin cover 30. In this embodiment, the groove is located on the basin cover 30, and the cylinder is located on the pivot shaft 4341.

[0045] Further, the second buffer member may be a second torsion spring 423, and the second torsion spring 423 may be disposed on the second connecting rod 42. One end of the second torsion spring 423 is fixed to the second connecting rod 42, and the other end is fixed to the basin body 10. When the side cover 20 is opened, the second torsion spring 423 is in a power storage process.

[0046] In other embodiments of the present invention, the first buffer member is a first rubber block 4321. One end of the first rubber block 4321 is fixed to the basin body 10, and the other end of the first rubber block 4321 is used to abut against the upper end of the second connecting rod 42. The second buffer member is a second rubber block 4231. One end of the second rubber block 4231 is fixed to the basin body 10, and the other end of the second rubber block 4231 is used to abut against the lower end of the second connecting rod 42. That is, the first rubber block 4321 and the second rubber block 4231 are respectively disposed at the upper and lower ends of the second connecting rod 42 to abut against the second connecting rod 42 from both sides.

[0047] Preferably, the basin body 10 is further provided with a protective cover 16 to protect the driving mechanism 40. The protective cover 16 is detachably mounted on the basin body 10. With such a setting, it is convenient for the user to disassemble the protective cover 16 and then clean and replace the combing rake 122.

[0048] Compared with the prior art, the cat litter box 100 of the present invention realizes the linkage between the basin cover 30 and the side cover 20 through the driving mechanism 40, so that when the user opens the basin cover 30, the side cover 20 can be automatically opened, which is convenient for the user to clean, replace, repair, etc., and avoids the problem that the inside of the existing drum-type cat litter box is difficult to clean.

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
