US 2026/0283097 A1 · SELF-CLEANING LITTER BOX

Abstract

The disclosed system, methods, and apparatus relates to a self-cleaning litter box. The self-cleaning litter box includes a movable rake. A mechanism controlling the rake can allow for control of the forward/reverse position, the vertical position, and the rotation of the rake using a different path of travel for the forward and reverse traversals of the rake across the litter box. The controlled positioning of the rake can reduce force on the rake and other mechanical components, and more evenly distribute litter. Further, some implementations may include a dumping mechanism that involve the rake flipping so that clumps of pet waste are forcibly removed from the rake by a mechanical impact. Further implementations allow for removal/replacement of the rake.

Dependent claims

A litter box comprising:

a chassis assembly having a first end and a second end, the chassis assembly including a side frame;
a motor;
a waste container at the second end of the chassis assembly;
a litter container placed within a lower portion of the chassis assembly;
a rake assembly including a rake, the rake assembly being movable between the first end and the second end of the chassis assembly, the rake assembly including a spring-loaded locking screw;
a carrier assembly including a support with an aperture configured to receive the spring-loaded locking screw to attach the rake assembly to the carrier assembly;
a drive mechanism operably connected to the carrier assembly, the drive mechanism being engageable by the motor to move the carrier assembly between the first end of the chassis assembly and the second end of the chassis assembly;
and
a guide path formed along the side frame, the guide path defining a path of travel of the rake from the first end toward the second end.
