Due to the arrangement of the shielding door 160, when the sand bin 130 is at the initial position, the shielding door 160 is located above the drain port 113 to shield the drain port 113, so that the odor in the excrement collecting bin 111 can be prevented from entering a gap between the sand bin 130 and the concave part 112 in the base 110, and further the odor is prevented from being emitted into the air to influence the living environment of a pet owner. When the pet sand 300 or the excrement 200 in the sand silo 130 needs to be discharged, the sand silo 130 rotates forwards or reversely from the initial position to the predetermined position and then drives the shielding door 160 to move relative to the discharge port 113 so as to expose the discharge port 113 until the opening 132 is aligned with the discharge port 113, and therefore the shielding door 160 does not prevent the pet sand 300 or the excrement 200 in the sand silo 130 from being discharged to the collecting silo 111, and the use experience of a user is improved. In addition, when the user cleans the sand silo 130, the user can not see the excrement in the collection bin 111 through the drain outlet 113, and the use experience is better. The shielding door 160 in the above embodiments can be detached, and can be conveniently cleaned when no electronic device is provided.
