[0031] The base 1 has a curved concave surface 11 at its top, and a support roller at its bottom. The litter drum 5 is mounted on this surface and supported by the support roller. The drive mechanism includes a motor 41 and a drive gear 4. Motor 41 is mounted within the base 1 and is in transmission connection with the drive gear 4, which is mounted at the front end of the lower end plate 2. A gear ring 6 is mounted concentrically with the central axis 61 at the rear end of the litter drum 5, meshing with the drive gear 4. In this embodiment, the motor 41 drives the drive gear 4 via a pulley drive pair. The outer diameter of the drive gear 4 is smaller than that of the gear ring 6, thus providing a reduction gear.

[0032] The front end of the lower end plate 2 is provided with a lower semicircular groove 21, the driving gear 4 is located at the bottom of the lower semicircular groove 21, the front end of the upper end plate 3 is provided with an upper semicircular groove 31, and the gear ring 6 is located in the area enclosed by the lower semicircular groove 21 and the upper semicircular groove 31.

[0033] The left side of the lower end plate 2 is provided with a hinged ear 22, and the right side is provided with a convex buckle 24; the left side of the upper end plate 3 is provided with a pivot hinged to the hinged ear 22, and the right side is provided with a buckle 34 buckled with the convex buckle 24, and the upper semicircular groove 31 of the upper end plate 3 is open front and back on the right side to form an arc-shaped elastic arm 33 at the edge of the right side of the upper end plate 3, and the lower end of the arc-shaped elastic arm 33 extends downward, and the buckle 34 is arranged on the inner side of the lower end of the arc-shaped elastic arm 33.

[0034] The upper semicircular groove 31 of the upper end plate 3 forms a retaining edge 32 on the right side of the back plate, and a retaining plate 37 extends upward from the rear end of the lower end plate 2. The front end of the retaining plate 37 is provided with an L-shaped limit buckle 25, which blocks the retaining edge 32.

[0035] The lower portion of the lower end plate 2 corresponding to the convex buckle 24 is provided with a finger buckle groove 26 for facilitating the insertion of a finger to lift the lower end of the arc-shaped elastic arm 33 to unlock the upper end plate and subsequently remove the cat litter drum 5.

[0036] The support rollers include a middle support roller 12 and a front support roller 13 . A convex ring 55 is provided at the open outer end of the cat litter drum 5 , and the outer periphery of the convex ring 55 is supported on the front support roller 13 .

[0037] The inner circumference of the cat litter drum 5 is sequentially distributed with a litter basin area 59, a sand collecting chamber 56 and a feces collecting chamber 57. A sand filter net 54 and a feces guide plate 53 are sequentially provided between the sand collecting chamber 56 and the corresponding litter basin area 59 and the feces collecting chamber 57. A feces collecting opening 58 is provided on the inner side of the feces collecting chamber 57.

The pressure ring 513 and the bag opening are then buckled together to secure the garbage bag 7 to the pressure ring 513. At the same time, since the opening of the garbage bag covers the pressure ring, it prevents the pressure ring from sticking to cat feces, which is more hygienic.

[0039] The front end of the base 1 is provided with a recessed portion 15, and a slot 14 is provided in the recessed portion 15. The slot 14 can be matched with some small accessories, such as Figure 8 As shown, the small accessory is a ramp 8, and the upper bottom of the ramp is provided with a plug 81 which is plugged into the slot 14, so that the kitten can climb into the cat litter drum 5 through the ramp. Figure 9 As shown, the second small accessory is a tag 9. When there are multiple kittens, the tags 9 can be placed in the slots 14 of different litter boxes, and each kitten can be guided to its own litter box to defecate.

[0040] A control panel 16 is also provided at the front end of the base 1 .

[0041] Its working principle is: when Figure 4 When the litter basin area 59 in the state contains a mixture of sand and feces, the cat litter drum 5 is rotated counterclockwise, and the sand and feces mixture reaches the sand filter net 54. The cat litter passes through the sand filter net 54 and enters the sand collecting chamber 56. The cat feces with cat litter remain on the mesh surface of the sand filter net 54. The cat litter continues to rotate counterclockwise, and the filtered cat litter accumulates in the area behind the feces guide plate 53. The cat feces then rolls through the feces guide plate 53 to the feces collection port 58 and falls into the garbage bag 7 of the feces collection chamber 57; at this time, the user can take out the garbage bag containing cat feces. The cat litter drum is rotated clockwise, and the cat litter in the sand collecting chamber 56 is re-introduced into the litter basin area 59. In addition, when the cat litter in the litter basin area 59 is uneven, the cat litter drum 5 can be controlled to continuously rotate slightly forward and reverse to level the cat litter.
