[0044] refer to Figures 1 to 8 A smart cat toilet and a control method according to an embodiment of the present invention are described.

[0045] like Figures 1 to 8 As shown, in order to solve the problem that the existing cat feces and cat urine agglomerates (cat urine and water-soluble cat litter agglomerates) need to be manually removed, and the cat urine agglomerates are both sticky and hard, and are usually difficult to remove manually. What's more, the so-called automatic cat feces processors on the market can only process some cat feces, but for cat urine agglomerates, they still need to be manually removed in the end. At the same time, cat feces and cat urine have a serious odor, which will spread rapidly if not cleaned in time, polluting the environment. For this reason, this embodiment provides a smart cat toilet and a control method, including a body 1, a cat litter box 10, a frame 20, a sewage discharge device 30, and a casing 40.

The tooth spacing of the poop shoveling rake 2111 is greater than the diameter or minimum size of the cat litter. The poop shoveling rake separates cat poop from cat litter during movement.

[0050] Furthermore, in some embodiments, when the driving device 212 drives the moving device 21 to move from the starting point to the end point, the poop scooping rake 2111 separates cat feces from cat litter. When the moving device reaches the end point, the driving device stops moving and the poop scooping mechanism is started at the same time, that is, the first driving motor 2121 stops working, and the second driving motor 2112 starts working, and the poop scooping rake 2111 flips 30 to 80 degrees to shovel the agglomerated cat feces into the sewage discharge device 30.

[0051] In addition, the frame 20 is provided with an in-position detection device 27 for detecting the in-position of the driving device 212. When it is detected that the frame 20 is in a designated position, the flushing device 22 and the stirring device 24 start to work.
