Cleaning device and control method thereof

A cleaning device, comprising:

• a chassis, the chassis being recessed to form a trough;
• a first drive mechanism comprising a first motor, the first drive mechanism being mounted on the chassis;
• a rotating plate and a cleaning plate, the rotating plate being fitted to and mounted in the trough, the cleaning plate being eccentrically mounted to the rotating plate, the rotating plate being provided with a transmission structure, an input end of the transmission structure being in transmitting connection with the first drive mechanism, an output end of the transmission structure being in transmitting connection with the cleaning plate to drive the cleaning plate to rotate;
• a second drive mechanism comprising a second motor, the second drive mechanism being connected with the rotating plate, wherein driven by the second drive mechanism, the rotating plate is caused to rotate about an axis of the rotating plate, so that the rotating plate drives, through rotation thereof, the cleaning plate to move for displacement;
• and
• an elevation mechanism, wherein
• the elevation mechanism is connected with the first drive mechanism and configured to drive the cleaning plate to ascend or descend;
• when the first drive mechanism performs transmission in a first direction with respect to the transmission structure, the elevation mechanism drives the cleaning plate to ascend, and when the first drive mechanism performs transmission in a second direction with respect to the transmission structure, the elevation mechanism drives the cleaning plate to descend;
• and
• when the elevation mechanism drives the cleaning plate to descend to a lowest position, the rotating plate is located in the trough.
