Pet cat excrement screening device

Abstract

The invention relates to the technical field of pet supplies, and discloses a pet cat excrement screening device. The pet cat excrement screening device comprises a supporting base and a roller rotationally installed on the supporting base, a roller driving device is installed on the supporting base, the roller can be driven by the roller driving device to rotate between a first position and a second position, and the rotating angle of the roller is smaller than 360 degrees; a pet inlet is formed in the side wall of a roller body of the roller and is always exposed out of the supporting base in the rolling process of the roller; and a screening mechanism is installed in the roller, a waste discharge port is formed in the rear end of the roller, the screening mechanism comprises a screeningnet and a spiral collecting bin, the spiral collecting bin is provided with a spiral surface spirally bent towards the waste discharge port, the screening net is used for screening excrement from catlitter to the spiral surface, and the spiral surface is used for guiding the excrement into the waste discharge port along with rotation of the roller. According to the pet cat excrement screening device, the pet inlet is always exposed out of the supporting base, and the safety of a pet cat is guaranteed when the roller rotates by mistake.

Description

technical field [0001] The invention relates to the technical field of pet products, in particular to a pet cat excrement screening device. Background technique [0002] With the continuous improvement of people's material living standards, people's spiritual life requirements are also gradually improving, and there are more and more people who like to keep pet cats. Although many cat lovers like pet cats very much, they have no time to clean up the excrement produced by pet cats, so they have special automatic pet cat toilets. Among the existing automatic pet cat toilets, the drum-type automatic pet cat toilet based on the principle of gravity screening is becoming more and more mainstream in the development of similar products due to its high efficiency, stability, and easy maintenance. [0003] Under the existing technology, the drum-type automatic pet cat toilets based on the principle of gravity screening almost all need to rely on sensor detection and software algorit...
