  • Automatic trash bag sealing device in an automatic cat litter box and automatic cat litter box
    Patent number: 11793154
    Abstract: The present disclosure discloses an automatic trash bag sealing device for an automatic cat litter box and an automatic cat litter box. In the automatic trash bag sealing device, a drive motor drives a first rod and/or a second rod to rotate, thereby driving a pushing member to move towards a sealing member, and the trash bag is sealed when the sealing member is interfaced with the pushing member. The sealing device has fewer parts and is simple to assemble, effectively reducing the difficulty of process assembly and the overall cost of the automatic cat litter box.
