Pet toilet

Abstract

A pet toilet, characterized in that it comprises: a drum (1) having a first opening (11) and a first receiving chamber (12), wherein the first opening (11) is connected to the first receiving chamber (12), and wherein the first receiving chamber (12) is used to receive pet excrement and pet litter; a base (2) wherein the drum (1) is supported on the base (2), and wherein the base (2) has a second opening (21); a sieve component (3) connected to the drum (1), wherein the sieve component (3) and the inner wall of the drum (1) form a second receiving chamber (13), and wherein the second receiving chamber (13) adjoins the first receiving chamber (12), and wherein the sieve component (3) is used to sieve pet litter and excrement; a drive device (4) used to drive the drum (1) to rotate on the base (2);wherein, when the first opening (11) rotates from the initial position towards the excrement outlet position by the rotation of the drum (1), pet litter can enter the second receiving chamber (13) through the sieve component (3), with the excrement being retained outside the second receiving chamber (13), and wherein, when the first opening (11) rotates by the rotation of the drum (1) until it aligns with the second opening (21), the first opening (11) is connected to the second opening (21) so that the excrement can exit through the first opening (11) and the second opening (21) under its own weight;and wherein, when the first opening (11) rotates from the excrement outlet position to the starting position by the rotation of the drum (1), the first opening (11) is offset from the second opening (21) and the drum (1) covers the second opening (21), and wherein the pet litter in the second receiving chamber (13) can pass through the sieve component (3) and fall back into the first receiving chamber (12) under its own weight; and wherein the pet toilet further comprises an internal infrared sensing device (10) attached to the base (2) and a control main board (44), and wherein the internal infrared sensing device (10) is electrically connected to the control main board (44) to detect whether a pet has entered the second opening (21), thereby preventing the pet from being trapped and injured;and wherein the inner infrared detection device (10) is located above the second opening (21), and wherein, when the first opening (11) rotates from the excrement outlet position to the starting position due to the rotation of the drum (1), and the inner infrared detection device (10) detects that a pet has entered the second opening (21), the main control board (44) controls the drive device (4) to cause the drum (1) and the first opening (11) to rotate back towards the excrement outlet position.
