Transmission assembly and cleaning device

Abstract

The application discloses a transmission assembly and a cleaning device. The transmission assembly is connected to a cleaning assembly, and drives the cleaning assembly to rotate in a first direction or a second direction. The first direction is opposite to the second direction. The transmission assembly comprises a first transmission member and a second transmission member. The second transmission member is connected to the first transmission member. The second transmission member is provided with a track surface. The first transmission member is movably abutted on the track surface. In the second direction, the track surface comprises a first region and a second region. When the first transmission member is abutted on the first region, the cleaning assembly is located at a cleaning position in contact with the ground. When the first transmission member is abutted on the second region, the cleaning assembly is located at a ground-leaving position away from the ground. The application solves the problem of low precision of the existing technology using a lead screw to realize the lifting of a mop.
