[0034] Reference Figures 1 to 4 This utility model proposes a self-cleaning cat litter box, including: a bottom shell 1, the upper end surface of the bottom shell 1 having a plurality of sliding holes 101, a push rod 102 slidably connected to each of the plurality of sliding holes 101, an adjusting plate 103 fixedly connected to the bottom end of the plurality of push rods 102, and an ejection drive assembly 2 connected to the adjusting plate 103 to drive the push rods 102 to eject from the upper end surface of the bottom shell 1;

[0035] The cleaning mechanism 3 includes a top shell 301 installed on the upper surface of the bottom shell 1. A through groove 302 is provided on the first side of the top shell 301. A control plate 303 is slidably connected to the through groove 302. A threaded adjusting rod 304 is threadedly connected to the control plate 303. An adjusting motor 305 is also provided on the first side of the top shell 301. The threaded adjusting rod 304 is fixedly connected to the output shaft of the adjusting motor 305. A pull plate 306 is fixedly connected to one side of the control plate 303. A plurality of push rods 307 are provided on one end face of the pull plate 306. A drain port 308 is also provided on the second side of the top shell 301 perpendicular to the axial direction of the threaded adjusting rod 304.

[0036] In the above embodiment, the bottom shell 1 and the cleaning mechanism 3 work together to achieve efficient cleaning of cat litter. The upper surface of the bottom shell 1 has several sliding holes 101, through which a top rod 102 is slidably connected. The bottom end of the top rod 102 is fixedly connected via an adjusting plate 103, which is further connected to the ejection drive assembly 2. When the ejection drive assembly 2 is activated, the adjusting plate 103 pushes the top rod 102 upwards along the sliding holes 101, thereby ejecting the clumps of cat litter inside the bottom shell 1 to the upper surface of the bottom shell 1. This structural design effectively solves the problem of low cleaning efficiency of traditional vibrating filters through mechanical pushing, and provides a basis for subsequent separation operations, ensuring a more efficient and reliable cleaning process.

[0037] The cleaning mechanism 3 is installed on the upper surface of the bottom shell 1. Its core is the top shell 301. A through groove 302 is opened on the first side of the top shell 301. A control plate 303 is slidably connected in the through groove 302. The control plate 303 is fixedly connected to the adjusting motor 305 through a threaded adjusting rod 304. When the adjusting motor 305 drives the threaded adjusting rod 304 to rotate, the control plate 303 can move precisely along the through groove 302. At the same time, through the fixedly connected pull plate 306 and several push rods 307 set on the end face of the pull plate 306, a pushing force is applied to the ejected clumps of cat litter or excrement, pushing them towards the drain port 308 on the second side of the top shell 301, and finally completing the discharge of waste. The design of this cleaning mechanism makes the movement of clumps of cat litter more stable, avoiding the problems of component wear and incomplete cleaning in traditional vibration methods. At the same time, the reasonable arrangement of the drain port 308 further optimizes the collection and discharge path of waste, reduces the complexity of user maintenance, and significantly improves the cleaning effect and reliability of the device.

[0038] In summary, by setting the ejection drive assembly 2 to push the adjusting plate 103 to move the push rod 102 upward, the clumps of cat litter containing excrement can be effectively pushed, separating the clumps from the clean cat litter. Using the cooperation of the control plate 303 and the threaded adjusting rod 304, the pull plate 306 pushes the push rod 307 to move, allowing the push rod 307 to push the ejected clumps of cat litter towards the drain outlet 308 for smooth discharge. This effectively solves the problem of the cleaning mechanism 3 failing to return to its efficient position, achieving efficient separation and cleaning of cat litter and excrement, and significantly improving cleaning efficiency.

The bottom end of the ejector threaded rod 201 is fixedly connected to the output shaft of the ejector drive motor 202, which is mounted on the inner bottom wall of the bottom shell 1, thereby providing stable support through the bottom shell 1. In this structure, the ejector drive motor 202 drives the adjusting plate 103 to move along the threaded rod axial direction by rotating the ejector threaded rod 201, further pushing the ejector rod 102 upward along the sliding hole 101, thereby realizing the ejection function of cat litter inside the bottom shell 1.
