[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] See Figures 1-5 An open-type automatic litter box includes: a base 1 and a roller 2, the roller 2 being rotatably mounted on the base 1, and having an opening; the roller 2 also includes: a sand filter compartment 210 and a waste collection compartment 27; a sand guide plate 24 guiding litter clumps into the waste collection compartment 27; and a sand filter screen 29 guiding litter into the sand filter compartment 210, preventing litter clumps from passing through the sand filter screen 29; during the rotation of the roller 2, litter clumps are guided into the waste collection compartment 27 and litter into the sand filter compartment 210. After the cat uses the litter box, it automatically scoops the litter, eliminating the need for manual cleaning and ensuring hygiene. A motor 13, rotating forward, separates the waste clumps from the clean litter; the clean litter passes through the sand filter screen 29 into the sand filter compartment 210, while the waste clumps are transferred along the sand guide plate 24. A weight sensor detects when the cat has used the litter box and automatically scoops the litter after the cat leaves.

[0029] The upper end of the sand filter chamber 210 is also provided with an upper movable door 25. The first end of the upper movable door 25 is hinged to the opening of the feces collection chamber 27; the second end of the upper movable door 25 covers the end of the sand guide plate 24. The upper movable door 25 opens automatically by gravity and the impact of the feces, and the feces enter the upper cover 23.

[0030] The upper end of the filter sand chamber 210 is also provided with a lower movable door 26. The first end of the lower movable door 26 is hinged to the opening of the feces collection chamber 27; the second end of the lower movable door 26 overlaps with the lower side wall of the opening of the feces collection chamber 27. The lower movable door 26 is positioned and blocked by a torsion spring to prevent the feces in the feces collection chamber 27 from flowing back and overflowing.

[0031] The waste collection chamber 27 is also equipped with a waste collection chamber cover 28, which is hinged to the waste collection chamber 27. The waste collection chamber cover 28 can be opened to facilitate cleaning of the waste collection chamber 27.

[0032] A drive mechanism for rotating the roller 2 is also provided. The drive mechanism is a gear mechanism, including a large gear 21, a small gear 12, and a motor 13. The large gear 21 is fixed on the side wall of the roller 2, the motor 13 is mounted on the base 1, and the small gear 12 is connected to the rotating shaft of the motor 13, meshing with the large gear 21. When the motor 13 reverses, the stool clumps open the lower movable door 26 and enter the stool collection chamber 27. The upper movable door 25 returns to its original position by gravity, covering the stool outlet and preventing odor from escaping from the stool collection chamber 27.

[0033] The base 1 is also provided with side plates 11 on both sides, and the roller 2 is rotatably mounted on the side plates 11 on both sides. The bottom of the roller 2 is also provided with a bottom pad 211. The base 1 is also provided with rollers 14 that are adapted to the roller 2.

[0034] The top cover 23, sand guide plate 24, sand filter screen 29, and bottom pad 211 are all fixed with sliding grooves, locking positions, and Torx bolts, making it convenient for consumers to disassemble and reducing cleaning dead corners.

[0035] The machine is equipped with gravity sensors inside its four support feet. It pauses operation immediately when a cat enters and resumes operation only after the cat leaves. The machine operates without any sharp angles, eliminating the risk of trapping a cat. The open roller provides a larger litter box. The waste collection chamber is integrated into the roller, saving space. The roller's sides and bottom are connected to the base with casters for smoother rotation. An additional movable small filter screen ensures more thorough litter output and reduces litter residue.

[0036] With the above structure, the litter box can be automatically cleaned after the cat finishes using the litter box, eliminating the need for manual cleaning and ensuring cleanliness and hygiene.
