[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] See Figures 1-4 This utility model discloses a self-cleaning cat litter box, including a basin body 10, a cleaning component, and a driving component. Specifically, a litter chamber 11 is provided in the basin body 10, and the cleaning component includes a cleaning element 20 and a filter element 30. The cleaning element 20 is provided with a cleaning cavity 23 and a plurality of cleaning teeth 21. The cleaning element 20 can be rotatably installed in the litter chamber 11. The cleaning cavity 23 is provided with a cleaning opening in the rotation direction, and a sand passage opening is provided at the bottom of the cleaning cavity 23. The plurality of cleaning teeth 21 are provided in the cleaning opening. In addition, the filter element 30 can be detachably installed in the cleaning cavity 23 to receive cat litter entering the cleaning cavity 23 for filtration. The filter element 30 is provided with a plurality of filter holes 31, and the plurality of filter holes 31 correspond to the sand passage opening. The driving component is used to drive the cleaning element 20 to rotate.

[0028] Based on the above structure, when using the self-cleaning cat litter box of this utility model, a cat litter chamber 11 can be provided in the basin body 10 for storing cat litter. Then, the driving component is electrically connected to an external power source and drives the cleaning component 20 to rotate. The cleaning component 20 is rotatably installed in the cat litter chamber 11. The cleaning component 20 is provided with a cleaning chamber 23 and several cleaning teeth 21. The cleaning chamber 23 is provided with a cleaning opening in the rotation direction. Several cleaning teeth 21 can be provided in the cleaning opening. A litter passage can be provided at the bottom of the cleaning chamber 23.

[0029] With this setup, when the litter box needs cleaning, the drive unit, electrically connected to an external power source, can rotate the cleaning unit 20 within the litter chamber 11. Since the cleaning chamber 23 has a cleaning opening in the rotation direction, several cleaning teeth 21 can be positioned at the opening. As the cleaning unit 20 rotates within the litter chamber 11, litter and excrement are guided into the cleaning chamber 23 through the cleaning teeth 21 and cleaning opening. A sand passage is located at the bottom of the cleaning chamber 23, allowing litter to flow out. Excrement, such as feces or urine, remains in the cleaning chamber 23 because feces are too large to pass through the sand passage. Urine, when discharged into the litter, causes the litter to clump together, forming large clumps that also cannot pass through the sand passage and remain in the cleaning chamber 23. This allows for the separation of excrement from uncontaminated litter, eliminating the need for manual cleaning of the litter box.

[0030] In addition, the filter element 30 can be detachably installed in the cleaning chamber 23 to receive the cat litter entering the cleaning chamber 23 for filtration. The filter element 30 can be provided with multiple filter holes 31, and the multiple filter holes 31 are arranged corresponding to the above-mentioned sand passage.

[0031] For example, a slot can be provided on the cleaning chamber 23 and a slot can be provided on the filter element 30. The filter element 30 is snapped into the cleaning chamber 23 by snapping into the slot. This allows the filter element 30 to rotate with the cleaning element 20 in the litter chamber 11. Cat litter and excrement can be guided into the filter element 30 through the cleaning teeth 21 and the cleaning opening. The filter element 30 is provided with multiple filter holes 31 and the multiple filter holes 31 are correspondingly set with the litter outlet. This allows cat litter to flow out of the filter element 30 through the filter holes 31 and then out of the cleaning chamber 23 through the litter outlet. Cat excrement, such as feces or urine, cannot pass through the filter holes 31 due to its large volume and remains in the filter element 30. When urine is discharged into the litter, it causes the litter to clump together, forming large clumps that also cannot pass through the filter holes 31 and remain in the filter element 30. This allows the excrement and uncontaminated litter to be separated by the filter element 30. Then, by removing the filter element 30 from the cleaning chamber 23, the excrement can be removed from the litter box along with the filter element 30, thereby improving cleaning efficiency.

[0032] Furthermore, the cleaning component 20 includes a rotating shaft 22 and a cleaning bracket. The rotating shaft 22 can be connected to the side of the cleaning bracket and rotatably engaged with the litter box 11. The cleaning box 23 is located on the cleaning bracket, and the filter element 30 can be detachably connected to the cleaning box 23. The driving component is used to drive the rotating shaft 22 to rotate.

[0033] With this configuration, the drive unit, electrically connected to an external power source, can drive the rotating shaft 22 to rotate. The rotating shaft 22 is connected to the side of the cleaning bracket and rotatably engages with the litter box 11. This allows the cleaning bracket to rotate within the litter box 11 as the rotating shaft 22 rotates. The cleaning chamber 23 is located on the cleaning bracket, allowing it to collect litter and excrement from the litter box 11. The filter element 30 is detachably connected to the cleaning chamber 23. After the litter and excrement in the litter box 11 are collected in the cleaning chamber 23, they are filtered and separated by the filter element 30. Uncontaminated litter can return to the litter box 11 through the filter holes 31 on the filter element 30 and the sand passage on the bottom wall of the cleaning chamber 23. Excrement can be removed from the cleaning chamber 23 after passing through the filter element 30. This eliminates the need for manual cleaning of excrement in the litter box, improving cleaning efficiency.

[0034] It should be noted that the filter element 30 is connected to the cleaning chamber 23 in a detachable manner, which can be achieved by a snap-fit ​​structure in the prior art. For example, a slot can be provided on the cleaning chamber 23, and a locking block can be provided on the filter element 30. The filter element 30 can be detached and installed in the cleaning chamber 23 by the locking block engaging with the slot. This setting makes detachment and installation simple and facilitates later maintenance.

[0035] Furthermore, a rotating seat 12 can be provided in the middle of the litter box 11, and the rotating shaft 22 can be rotatably inserted into the rotating seat 12. When it is necessary to clean the litter in the litter box 11, the rotating shaft 22 can be rotatably inserted into the rotating seat 12, and the cleaning component 20 is also placed in the litter box 11 along with the rotating shaft 22 and rotates in coordination with the litter box 11. Then, after the drive component is connected to an external power source, it drives the rotating shaft 22 to rotate, causing the cleaning component 20 to rotate in the litter box 11, so that the cleaning component 20 can collect the excrement in the litter box 11. When cleaning is completed or when it is necessary to clean and maintain the cleaning component 20, the rotating shaft 22 can be removed from the rotating seat 12, and the cleaning component 20 is also removed from the litter box 11. This eliminates the space occupied by the cleaning component 20 in the litter box 11, so that the space in the litter box 11 is used rationally and the flexibility of the litter box is enriched.

[0036] Furthermore, the driving component can be installed at the bottom of the basin 10. The driving component includes a drive motor 41 and a gear transmission mechanism 42. The rotating shaft of the drive motor 41 can be connected to the rotating shaft 22 through the gear transmission mechanism 42. The gear transmission mechanism 42 can be a gear transmission mechanism 42 in the prior art. This allows the drive motor 41 to drive the rotating shaft 22 to rotate through the gear transmission mechanism 42 after being electrically connected to an external power source, thereby improving the stability of the rotating shaft 22 when it rotates.

[0037] Furthermore, the cleaning teeth 21 gradually slope downwards from the end closest to the cleaning opening to the end furthest from the cleaning opening. This arrangement creates a ramp structure for the cleaning teeth 21, which gradually slopes upwards from the end furthest from the cleaning opening to the cleaning opening. As the cleaning teeth 21 rotate with the cleaning chamber 23, they can gradually guide cat litter and excrement to the cleaning opening and then flow into the cleaning chamber 23.

[0038] Furthermore, the filter element 30 includes a filter box, which may have a filter port 32. The filter port 32 is used to correspond to the cleaning opening after the filter box is installed in the cleaning chamber 23. A filter hole 31 is provided on the bottom wall of the filter box, so that the cat litter and excrement in the litter chamber 11 can reach the filter box through the cleaning opening and the filter port 32, while the uncontaminated cat litter can be discharged through the filter hole 31 provided on the bottom wall of the filter box, thus preventing the cat litter from accumulating in the filter box.

[0039] Furthermore, filter holes 31 can be provided on the side wall of the filter box away from the filter port 32. This can improve the filtration efficiency of the filter box and prevent cat litter from accumulating inside the filter box and affecting the filtration effect.

[0040] Furthermore, a handle 33 is provided at the top of the filter box, making it easy for a person to remove the filter box from the cleaning chamber 23 by hand.

[0041] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
