The outer portion 245 has a first positioning post 2451 in the center and third connecting holes 2452 on both sides. The first positioning post 2451 is connected to the first connecting hole 2441, and the second connecting holes 2442 and third connecting holes 2452 are connected by screws. Through the above structure, the sand-blocking box 24 is effectively installed, and the edge of the first opening 11 of the roller 1 can rotate within the first limiting groove 4211, ensuring that the sand-blocking box 24 does not affect the normal rotation of the roller 1 and improving the stability of the roller 1's rotation and cleaning.

[0069] In this embodiment, the sieve assembly 3 has a first connector 311 and a screen portion 32. The first connector 311 is connected to the inner wall of the roller 1. One side of the screen portion 32 is rotatably connected to the first connector 311. When the roller 1 rotates from the initial position to the excretion position, the other side of the screen portion 32 abuts against the inner wall of the roller 1 under its own gravity. Pet litter can enter the third receiving space 31 through the screen portion 32 of the sieve assembly 3. Excrement is restricted outside the third receiving space 31, and excrement can be discharged into the second receiving space 41 through the second opening 42 under its own gravity. When the roller 1 rotates from the excretion position to the initial position, the other side of the screen portion 32 detaches from the inner wall of the roller 1 under its own gravity, so that a pet litter channel 33 is formed between the other side of the screen portion 32 and the inner wall of the roller 1. Pet litter in the third receiving space 31 can pass through the screen portion 32 and the pet litter channel 33, and fall back into the first receiving space 12 under its own gravity. With the above structure, when the roller 1 rotates from the discharge position to the initial position, the other side of the screen part 32 detaches from the inner wall of the roller 1 under its own gravity, so that a pet litter channel 33 is formed between the other side of the screen part 32 and the inner wall of the roller 1. The pet litter in the third receiving space 31 can pass through the screen part 32 and the pet litter channel 33, and fall back into the first receiving space 12 under its own gravity. This facilitates the rapid return of pet litter to the first receiving cavity, prevents litter from getting stuck, and prevents pet litter from accumulating in the third receiving space 31.

[0070] In this embodiment, a support arm 9 is also included, which is supported on the second end 14 of the roller 1. The support arm 9 is movably connected to the base 2, allowing it to move between a folded storage position and a supported position. The support arm 9 has a rotating groove 91, and the second end 14 of the roller 1 has a rotating shaft 141, which can rotate within the rotating groove 91. The support arm 9 is rotatably connected to the base 2, allowing it to move between a folded storage position and a supported position. With this structure, when a pet toilet needs to be used, the support arm 9 can be rotated to the supported position to support the roller 1. When the pet toilet is not needed, or when it needs to be transported, the support arm 9 can be rotated to the folded position to reduce the size of the pet toilet, making it easier to store, pack, and transport.

[0071] In this embodiment, the base 2 has a mounting sidewall 25 and a mounting top wall 26, which are connected. The inner surface 9111 of the support arm 9 is rotatably connected to the base 2. When the support arm 9 is rotated to the folded storage position, the inner surface 9111 of the support arm 9 abuts against the mounting top wall 26 of the base 2, so that the support arm 9 and the base 2 are stacked. When the support arm 9 is rotated to the unfolded position, the inner surface 9111 of the support arm 9 abuts against the mounting sidewall 25, so that the support arm 9 can support the second end 14 of the roller 1. A hinge 92 is also included, one end of which is detachably connected to the inner surface 9111 of the support arm 9, and the other end of which is rotatably connected to the inner surface 9111 of the support arm 9; or, a hinge 92 is also included, one end of which is rotatably connected to the inner surface 9111 of the support arm 9, and the other end of which is detachably connected to the inner surface 9111 of the support arm 9. The above structure is rationally designed, securely connected, and effectively achieves a rotatable connection between the support arm 9 and the base 2, facilitating user installation, folding, and unfolding of the support arm 9. For example, refer to... Figure 3 When the support arm 9 is rotated to the unfolded position, if storage or packaging is required, a large packaging box 229113 of a larger size is needed; when the support arm 9 is rotated to the folded storage position, the support arm 9 and the base 2 are stacked, and if storage or packaging is required, a small packaging box 229112 of a smaller size can be used for packaging.

[0072] In this embodiment, the support arm and the base are detachably connected, allowing the support arm 9 to move between a folded storage position and a supported position. The base has an insertion port 225, and the support arm has an insertion block 226, which is detachably inserted into the insertion port. Specifically, the insertion block is connected to the inner wall of the insertion port via a snap fastener 227 to lock the insertion block within the insertion port. Further, the inner wall of the insertion port has an elastic locking wall 2271, and the snap fastener includes a locking hook 2272 on the elastic locking wall and a locking block 2273 on the insertion block. The locking hook and the locking block are connected to lock the insertion block within the insertion port. Further, the insertion block has several positioning grooves 2261, and several positioning protrusions 2262 extend from the inner wall of the insertion port, with the positioning protrusions connected to the positioning grooves. Furthermore, the support arm is provided with a first conductive end 228, and the base is provided with a second conductive end 229. The base contains a power supply 2291 and a control motherboard 2292. The first conductive end is electrically connected to the drive device, and the second conductive end is electrically connected to the power supply and the control motherboard. When the support arm moves to the support position, the first conductive end and the second conductive end are electrically connected, so that the drive device, the control motherboard, and the power supply are interconnected through the first conductive end and the second conductive end. Through the above structure, a detachable connection between the support arm 9 and the base 2 is effectively achieved, which facilitates the user to install, disassemble, and unfold the support arm 9. The detached support arm can also be moved to a folded position, so that the support arm and the base are stacked on top of each other to reduce the volume of the pet toilet. In some embodiments, the first conductive end and the second conductive end are electrically connected by a wire 229111.

[0073] In this embodiment, the support arm 9 also has a gear mounting groove 93. The drive device 5 includes a drive motor 51, a drive gear 52, and a transmission gear 53. The drive gear 52 is disposed in the gear mounting groove 93, and the output shaft of the drive motor 51 is connected to the drive gear 52 for driving the drive gear 52 to rotate. The transmission gear 53 is disposed at the second end 14 of the roller 1, and the drive gear 52 and the transmission gear 53 are meshed together so that the rotation of the drive gear 52 can drive the transmission gear 53 and the roller 1 to rotate on the base 2 and the support arm 9. Through the above structure, the drive device 5 is effectively configured so that the drive motor 51 can drive the drive gear 52 and the transmission gear 53 to rotate, thereby driving the roller 1 to rotate on the base 2 and the support arm 9 to the initial position or the discharge position.
