Through the above structure, the first locking device 7 and the second locking device 73 are effectively set. When the support frame 6 is moved to the unfolded position, the first locking device 7 locks the support frame 6 in the unfolded position, so that the second support part 22 and the third support part 62 can more stably support the base 2, so that the support frame 6 can lift the first support part 21 of the base 2 upward, so as to lift the first end 13 of the roller 1 and the first opening 11 upward to the inclined position, so that the bagged pet litter can be poured into the first receiving space 12 through the first opening 11 under its own weight. After the pet litter is added, the support frame 6 can be moved to the folded position, and the first locking device 7 locks the support frame 6 in the folded position to prevent the support frame 6 from shaking, so that the user can take the support frame 6 out at any time.

[0056] In this embodiment, the support frame 6 has a hollow groove 63, and several reinforcing ribs 64 are provided inside the hollow groove 63. Through this structure, the design of the hollow groove 63 reduces the weight of the support frame 6, thereby reducing the overall weight of the pet toilet and facilitating its transportation. Furthermore, the design of the hollow groove 63 saves materials used in the production of the support frame 6, making it more environmentally friendly.

[0057] In this embodiment, a door cover 1300 is also included. The door cover 1300 is rotatably connected to the roller 1, and the door cover 1300 opens or closes the second opening 42. When the roller 1 rotates to the discharge position, the door cover 1300 rotates under its own weight to open the second opening 42. When the roller 1 rotates to the initial position, the door cover 1300 rotates under its own weight to close the second opening 42. A limiting support column 131 is also provided on the inner side of the door cover 1300. When the roller 1 rotates to the discharge position, the door cover 1300 rotates under its own weight to open the second opening 42, and the limiting support column 131 is supported on the inner wall of the waste collection chamber 4. Specifically, the inner side of the door cover 1300 is also provided with a first insertion groove 132. The side wall of the first insertion groove 132 has multiple clearance slits 1321 and multiple elastic walls 1322 formed between the clearance slits 1321. The limiting support column 131 is inserted into the first insertion groove 132, and the elastic walls 1322 press the limiting support column 131 into the first insertion groove 132. With the above structure, when the roller 1 rotates to the discharge position, the door cover 1300 rotates under its own weight to open the second opening 42, so that the excrement flows into the collection chamber 4. When the roller 1 rotates to the initial position, the door cover 1300 rotates under its own weight to close the second opening 42, preventing the excrement from flowing out of the collection chamber 4, and can also seal the collection chamber 4 to prevent the odor of the excrement from escaping from the collection chamber 4. Furthermore, due to the presence of a limiting support column 131, when the door cover 1300 is opened, a backflow prevention space is formed between the inner side of the door cover 1300 and the inner wall of the feces collection chamber 4. This backflow prevention space can prevent excrement entering the feces collection chamber 4 from entering. The limiting support column 131 is an elastic limiting support column. Specifically, when a large clump of cat feces needs to enter the feces collection chamber 4, the adjustable angle of this elastic column will decrease, increasing the passage rate of larger clumps. When the roller 1 rotates to the excretion position, this angle is at its default larger angle, preventing previously entered clumps of cat feces from rolling out of the feces collection chamber. Further, the elastic support column can be made of elastic material, or it can be an elastic support column connected to a spring 133. For example, a spring 133 can be provided between the first insertion slot 132 and the support column 131 to achieve the aforementioned technical effects.

[0058] In this embodiment, the waste collection chamber 4 also has a third opening 43 and a mounting cover 44, which is used to open or close the third opening 43.

The push button 44111 is connected to the locking hook 44112, and the elastic reset member 44113 is connected to the push button 44111. The elastic reset member 44113 is used to push the push button 44111 and the locking hook 44112 to push and lock the locking hook 44112 into the locking port 442. When an external force greater than the elastic reset force provided by the elastic reset member 44113 is applied to the push button 44111, the push button 44111 can be pushed to push the locking hook 44112 out of the locking port 442. Furthermore, the roller 1 is also provided with a locking buckle mounting groove 4414, and includes a locking cover plate 44115. The locking buckle 441 is installed in the locking buckle mounting groove 4414, and the locking cover plate 44115 is detachably closed onto the locking buckle mounting groove 4414, and the locking cover plate 44115 stops the locking buckle 441 within the locking buckle mounting groove 4414. With the above structure, the user can push the push button 44111 to push the locking hook 44112 out of the locking port 442, and rotate the mounting cover 44 to open the third opening 43, making it convenient for the user to clean the excrement in the collection chamber 4.

The first connecting portion 82 and the first connecting mating portion 81 are detachably connected so that the tightening strap 8 forms a tightening space around it. The tightening space of the tightening strap 8 is used to tighten the garbage bag to the connecting sidewall 421. With the above structure, the garbage bag can be placed on the connecting sidewall 421 at the second opening 42, and then tightened to the connecting sidewall 421 by the tightening strap 8 to prevent the garbage bag from loosening. Furthermore, because of the tightening strap 8 that tightens the garbage bag to the connecting sidewall 421, the waste collection chamber 4 can use any type of garbage bag, eliminating the need for a specific drawstring garbage bag, greatly improving the user experience.

[0060] In this embodiment, the first connecting part 82 is a first connecting buckle, and the first connecting mating part 81 is a first connecting socket. The first connecting buckle and the first connecting socket are detachably connected.

With this structure, the connecting lugs 4212 facilitate the user fitting the garbage bag, and the tightening strap 8 tightens the garbage bag within the first limiting groove 4211, preventing the garbage bag and the tightening strap 8 from sliding.

[0061] In this embodiment, a litter box 24 is also included. The litter box 24 is connected to the base 2 and covers at least a portion of the first opening 11. The litter box 24 is used to contain pet litter within the first receiving space 12. With this structure, the litter box 24 can contain pet litter within the first receiving space 12, preventing it from overflowing and also preventing the pet from carrying litter out of the first receiving space 12 after defecation. Furthermore, since the litter box 24 is connected to the base 2, it does not need to rotate with the roller 1, allowing the roller 1 to rotate more smoothly and preventing the roller 1 from throwing pet litter out during rotation.

[0062] In this embodiment, the sand shield box 24 has an insertion portion 241 on its lower side, and the base 2 has a second insertion groove 242.

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.

[0064] 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.

[0065] 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 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, so that the support arm 9 can move between a folded storage position and a supporting position. With the above structure, when the pet toilet needs to be used, the support arm 9 can be rotated to the supporting position to support the roller 1. When the pet toilet is not needed, or when the pet toilet needs to be transported, the support arm 9 can be rotated to the folded position to reduce the volume of the pet toilet, making it easier to store, pack, and transport the pet toilet.

[0066] 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 reasonably designed and has a stable connection, effectively achieving a rotatable connection between the support arm 9 and the base 2, which facilitates the user's installation, folding, and unfolding of the support arm 9.

[0067] 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.
