Be equipped with the hub connection portion between the motor shaft of sand dish 2 and motor 10, the sand dish 2 is installed on the motor shaft through hub connection portion dismantlement formula.

In this embodiment, the shaft connecting part is arranged at the bottom of the sand table 2, the motor shaft of the motor 10 extends out of the top of the base 1, a mounting groove for mounting the motor 10 is arranged in the base 1, and the shell of the motor 10 is fixed on the mounting groove through a bracket, a screw and the like.

In this embodiment, a circuit board is disposed in the base 1, the circuit board is electrically connected to the motor 10 through a wire, and the base 1 may be externally connected to a power supply, or a battery chamber for accommodating a battery is disposed in the base 1.

In this embodiment, the second sand silo 12 is provided with a first guide ramp which guides the drainage mixture 19 towards the faeces collection chamber 14; one side of the filter screen 13 is provided with a second guiding inclined plane which guides the discharged mixture 19 to the excrement collecting chamber 14 and the first sand silo 11. The guide slopes of the second sand silo 12 and the screen 13 are on the same plane.

The excrement collecting box 4 is assembled and disassembled on the sand disc 2 in a buckling, magnetic attraction or concave-convex assembly mode.

The excrement collecting box 4 is provided with an upper cover 16 for covering the excrement collecting chamber 14, and the upper cover is assembled and disassembled on the excrement collecting box 4 in a buckling, magnetic attraction or concave-convex assembly mode.

The bottom of the base 1 is provided with a gravity sensor 17, and the control panel of the base 1 is provided with a biosensor 18.

The gravity sensor 17 is used for judging the toilet behavior of the pet entering the sand pan: be provided with gravity sensor 17 on four footing of base, can be used for detecting whether the pet gets into first sand silo 11 of sand table 2, get into first sand silo 11 when the cat, the time difference of leaving first sand silo 11 to the cat exceeds 10 seconds, then judges that the pet is like the lavatory action to be established.

In the present embodiment, the biosensor 18 is electrically connected to the circuit board through a wire, and the circuit board is electrically connected to a button or the like of the control panel through a wire. The circuit board is provided with a control program through computer recording.

The chamber 14 may have only one or a plurality of movable doors 15, and a plurality of the chambers 14 are arranged in an array on the inner peripheral wall of the waste box 4 so as to be independently openable and to increase the opening of the waste mixture 19 into the chamber 14.

Referring to fig. 4, when the motor 10 is started, the motor shaft drives the sand pan 2 and the excrement collecting box 4 to rotate simultaneously, after the motor 10 stops working, the motor shaft stops rotating, the sand pan 2 and the excrement collecting box 4 stop moving along with the motor shaft, sand loses the support of centrifugal force, and slides down from the second sand silo 12 under the action of gravity, passes through the filter screen 13 and returns to the first sand silo 11.

Because the bottom of the first sand bin 11 is gradually gentle, the sand surface cannot be completely leveled under the action of gravity, the thickness of the peripheral sand is higher than that of the central area, but the thickness of the peripheral sand does not hinder the next excretion use of the pet, and the adhesion of the excrement of the pet to the machine is more favorably prevented. For example, because the probability of the cat tail being in the central area is low when the cat is in use, the discharge points of most adult cats in the litter box are close to the edge, so the litter on the edge is thicker, which is more favorable for preventing the cat urine from penetrating to the bottom and causing the litter to be hardened on the bottom of the machine.

Referring to fig. 5, in order to achieve a smoother and more beautiful sand surface after automatic cleaning, the motor 10 may be further started to perform intermittent reciprocating inching rotation after the automatic cleaning is finished, so as to obtain a smoother and more beautiful sand surface.

The foregoing is a preferred embodiment of the present invention showing and describing the basic principles, main features and advantages of the present invention. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are intended to illustrate the principles of the invention, and that various changes and modifications may be made without departing from the spirit and scope of the invention, and the scope of the invention is to be protected.
