Description

Technical Field

[0001] The utility model relates to the technical field of cat litter boxes, in particular to a cat litter box with a drum purification function. Background Art

[0002] An automatic cat litter box is a device that can automatically separate cat feces and cat litter. It generally includes a base and a rotating drum. The cat feces and cat litter are separated by the rotation of the drum, so that the cat litter in the cat litter box is kept clean. At present, China Patent Publication No.: CN114793917B discloses a cat litter box with easy cat litter replacement. When the cat litter box is in use, the cat litter box rotates through the drum and the filter is set at the feces outlet. Only by rotating the drum, the cat feces in the cat litter can be filtered out and the cat feces can be cleaned and collected in the cat feces bin; however, in the above-mentioned cat litter box structure, during the long-term use of the cat litter box, the inside of the drum will have a peculiar smell due to the cat's defecation, and the peculiar smell will spread to the environment outside the cat litter box, thereby polluting the environment around the cat litter box.
