Automatic cat litter box

Abstract

This invention relates to an automatic cat litter device, comprising a conveying mechanism, a sieving mechanism, and a transmission mechanism. The sieving mechanism is connected to the conveying mechanism; the transmission mechanism connects the sieving mechanism and the conveying mechanism. Cat litter is contained in the conveying mechanism, and after excretion, the conveying mechanism transports the used cat litter to the sieving mechanism. The sieving mechanism separates clumped cat litter from clean cat litter. The transmission mechanism then transports the clean cat litter back to the conveying mechanism for recycling, effectively separating clumps from clean cat litter, simulating the action of manually scooping litter, and thus achieving automatic litter replenishment.
