[0031] Example one:

[0032] refer to Figures 1 to 7The application discloses a cat litter basin anti-pinch structure which comprises a base 1, a cat litter bin 2 and a limiting structure 3. The cat litter bin 2 is provided with a central shaft 21 on both sides, and the base 1 is provided with a central hole 11 on both sides of the cat litter bin 2. The central shaft 21 is arranged in the central hole 11. The limiting structure 3 is used to limit the rotating stroke of the cat litter bin 2 on the base 1, so that the cat litter bin 2 has an anti-pinch space 4 with the base 1 in the rotating direction. The base comprises a lower hole seat 13 and an upper hole cover 14. The lower hole seat is provided with a lower half part 16 of the central hole, and the upper hole cover is provided with an upper half part 15 of the central hole. The upper hole cover and the lower hole seat are spliced to form the central hole. The upper hole cover can be rotated and opened relative to the lower hole seat. A driving mechanism (which can be a motor and is not shown in the figure) is arranged in the base. The output end of the driving mechanism is a driving gear 17. Correspondingly, a follow-up gear 22 is arranged on the central shaft and is engaged with the driving gear. The driving gear can drive the follow-up gear to rotate, that is, the driving mechanism can drive the cat litter bin to rotate.

[0033] Through the above structure, when in use, the central shaft of the cat litter bin can be arranged in the central hole of the base, so that the cat litter bin can rotate on the base. Moreover, the rotating stroke of the cat litter bin on the base can be limited by the limiting structure, so that the cat litter bin has an anti-pinch space with the base in the rotating direction. Especially when the driving mechanism of the cat litter bin fails, the limiting structure is particularly important, which can effectively prevent the cat from being pinched and eliminate the safety hazard of the existing cat litter basin.

[0034] The limiting structure 3 comprises a first stopper 31 and a second stopper 32. The first stopper 31 is arranged on the central shaft 21, and the second stopper 32 is arranged on the central hole 11. The first stopper 31 and the second stopper 32 are located on the same rotating circumference, so that the second stopper 32 forms a stop to the first stopper 31 of the central shaft 21 in the rotating direction, thereby limiting the rotating stroke of the central shaft 21. The second stopper 32 is arranged on the lower half part 16 of the central hole 11.

[0035] Specifically, the second stopper 32 is provided with a forward stop edge 33 and a reverse stop edge 34, when the litter box 2 is forward rotated to the first stopper 31 abutting against the forward stop edge 33, the litter box 2 has an anti-pinch space 4 with the base 1 in the direction of forward rotation; when the litter box 2 is reverse rotated to the first stopper 31 abutting against the reverse stop edge 34, the litter box 2 has an anti-pinch space 4 with the base 1 in the direction of reverse rotation. Through the above structure, even if the control mechanism fails, the maximum rotation stroke of the litter box is forward and reverse rotation between the forward stop edge and the reverse stop edge of the second stopper, so as to ensure that the forward rotation and the reverse rotation will reserve the anti-pinch space, and realize the anti-pinch effect of the cat. The width of the anti-pinch space is at least the size of the body of the cat, so as to ensure that the cat will not be pinched and cause injury.

[0036] Further, referring to Figures 8 to 11 , another structure of the second stopper is shown, the forward stop edge 33 is provided with a forward limiting groove 35, so that when the first stopper 31 abuts against the forward stop edge 33, the first stopper 31 is placed in the forward limiting groove 35; the reverse stop edge 34 is provided with a reverse limiting groove 36, so that when the first stopper 31 abuts against the reverse stop edge 34, the first stopper 31 is placed in the reverse limiting groove 36. The second stopper 32 is arranged in the lower half 16 of the center hole 11.

[0037] In the above structure, when the driving mechanism of the litter box fails, the litter box is rotated to the first stopper abutting against the forward stop edge, or the litter box is rotated to the first stopper abutting against the reverse stop edge, at this time, the driving mechanism (driving gear) exists the case of exerting upward lifting force on the center shaft, so that the upper half of the center hole (upper hole cover) will bear a large force; and since the upper hole cover can be rotated to open, it is not suitable to bear a large force. Therefore, by arranging the forward limiting groove on the forward stop edge and the reverse limiting groove on the reverse stop edge, the forward limiting groove and the reverse limiting groove can bear the above-mentioned force to a certain extent, that is, the lower hole seat (base) can bear the force, so that the overall structure is more balanced, and the product is more reliable and stable.

[0038] Further, the bottom of the forward limiting groove is provided with a forward avoiding part 37, and the bottom of the reverse limiting groove is provided with a reverse avoiding part 38, so as to facilitate the first stopper to be placed in the forward limiting groove or the reverse limiting groove, which is simple in structure and reasonable in design.

[0039] In this embodiment, the second stopper 32 is arc-shaped. The second stopper 32 and the side wall of the central hole 11 are integrally formed, which has a simple structure and is conducive to the structural layout of the product.

[0040] In this embodiment, the first stopper 31 is integrally formed with the central shaft 21 . The first stopper 31 is arc-shaped, has a simple structure, and is conducive to the structural layout of the product.

[0041] In this embodiment, the first stopper 31 is arranged outside the central axis 21 , and correspondingly, the second stopper 32 is arranged outside the central hole 11 , which has a simple structure and is conducive to the structural layout of the product.

[0042] In this embodiment, the inner wall of the center hole 11 is provided with a clearance groove 12 to reduce the friction between the center shaft 21 and the center hole 11. Specifically, the contact area between the center shaft and the center hole can be reduced, thereby reducing the friction.

[0043] Example 2:

[0044] Reference Figures 1 to 7 , a cat litter box, comprising the anti-pinch structure of the cat litter box as described above.

[0045] Because the cat litter box of this embodiment includes the aforementioned anti-pinch structure, the central axis of the litter bin can be positioned within the central hole of the base during use, allowing the litter bin to rotate on the base. Furthermore, the position-limiting structure limits the rotational travel of the litter bin on the base, ensuring an anti-pinch space between the litter bin and the base in the direction of rotation. The position-limiting structure is particularly important in situations such as when the litter bin's drive mechanism malfunctions, effectively preventing cats from becoming trapped and eliminating the safety hazards associated with existing litter boxes.

Any similarity or similarity with the methods, structures, etc. of the present invention, or any technical deduction or substitution based on the concept of the present invention, shall be deemed to be within the scope of protection of the present invention.
