Cleaning device can select the cat litter and clear up the excrement when rotating or removing in the cat litter basin in the past direction, can clear up the cat litter when rotating or removing in the opposite direction.

Referring to fig. 1, 2, 3 and 4, in an alternative embodiment, the cleaning device comprises a fixed plate 1 and a flap 2 rotatably fixed to the fixed plate 1. Turn over board 2 and be open state when clearance excrement, turn over board 2 and be closed state when clearance cat litter. Specifically, when the operation direction is clockwise rotation, the turning plate 2 is pushed away by the force from bottom to top. The cat litter slides out from the gap between the turning plates 2, and the cat litter is blocked by the gap between the turning plates 2 to rotate along with the cleaning device. When the traffic direction is anticlockwise rotation, turn over board 2 and receive from top to bottom power and close it, the cat litter moves along with cleaning device.

Referring to fig. 1 and 3, in an alternative embodiment, the cleaning apparatus further comprises tines 3 fixed to the fixed plate 1. Each rake tooth 3 is connected with a turning plate 2. Specifically, the turning plate 2 is matched with the rake teeth 3 to better block cat feces.

Referring to fig. 5, in an alternative embodiment, a spring 4 is further disposed between the fixed plate 1 and the rake teeth 3. Specifically, rake teeth 3 go up and down under the effect of spring 4, can adapt to the cat litter basin of the different degree of depth.

Referring to fig. 5 and 6, in an alternative embodiment, a mounting portion 21 is integrally connected to the turning plate 2, a locking block 22 is further connected to the turning plate 2, and the mounting portion 21 is rotatably mounted on the tine 3 after being clamped with the locking block 22. The mounting portion 21 is provided with a stopper groove 211 for stopping the flap when the flap is opened. The locking block 22 is provided with a limit protrusion 221 for limiting the turning plate when the turning plate is closed. Specifically, the mounting portion 21 is integrally connected to the flap 2. The locking block 22 and the mounting part 21 are clamped and then can be rotatably mounted on the rake teeth 3. The limiting groove 211 can prop against the rake teeth 3 when the turning plate is opened, and cannot be opened continuously. The turning plate 2 is blocked by the limit protrusion 221 when being closed, and is in a completely closed state.

Referring to fig. 5, in an alternative embodiment, the tines 3 are mounted parallel to the fixed plate 1. The rake teeth 3 comprise a telescopic part 31 arranged below the spring 4, an anti-rotation rod 32 extending from the tail end of the telescopic part 31, a clamping part 33 extending from the other end of the telescopic part 31 and used for installing the turning plate 2, an inclined limiting rod 34 extending from the tail end of the clamping part 33 and a bending part 35 extending from the tail end of the inclined limiting rod 34 and inclined towards the turning plate 2.

Referring to fig. 5, in an alternative embodiment, a lower cover 11 is provided at the bottom of the fixed plate 1, and the lower cover 11 fixes the spring 4 and the expansion part 31 in the fixed plate 1. In particular, the lower cover 11 and the fixed plate 1 can be detached, and the spring 4 is convenient to replace.

Referring to fig. 1, 7 and 8, in an alternative embodiment, a hinged end 12 is also provided on one side of the fixed plate 1. In particular, the fixing plates 1 can be hinged together through the hinge ends 12, so that the fixing plates can be conveniently used in cat litter boxes with different lengths. The fixed plate 1 with a specific length does not need to be customized, and the processing is convenient.

Referring to fig. 5, in an alternative embodiment, a beveled edge 23 is provided on flap 2. In particular, the inclined edge 23 increases the force to which the flap 2 is subjected when it is closed, making closure easier.

Referring to fig. 2, in an alternative embodiment, the maximum angle of the flap 2 with respect to the fixed plate 1 when the flap is opened is less than 90 °.

The specific working process is as follows:

as shown in fig. 7 and 8, the device of the present invention is used when used with a round litter box. One end of the fixing plate 1 is driven to rotate by a motor, and the other end of the fixing plate 1 is hinged with two fixing plates 1 in sequence. During the clockwise rotation, the flap 2 opens. The cat litter can be pushed by the gaps between the turning plates 2 and the rake teeth 3, and the cat litter is driven to rotate together until the cat litter is discharged. During the opening process of the turning plate 2, the limiting groove 211 of the turning plate 2 is abutted against the inclined limiting rod 34 so as to limit the turning plate 2 to be opened continuously.

One end of the fixing plate 1 is driven to rotate by a motor, and the turning plate 2 can be closed in the process of anticlockwise rotation. The turning plate 2 stops after contacting the adjacent turning plate 2. A sealed plate is formed between the turning plates 2, and the cat litter is driven to rotate together until the cat litter is cleaned up.

Example two:

the same structure as in the embodiment is adopted. When being used in square cat litter box, only need to push fixed plate 1 around. When the cat litter box is pushed downwards in fig. 2, the turnover plate 2 is opened to clean cat litter. When fig. 4 is pushed up, flap 2 can be closed to clean litter.

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modification, equivalent replacement or improvement made within the spirit and principle of the present invention should be included in the present invention.
