Abstract
Disclosed is a cleaning robot capable of simultaneously driving a driving wheel and an impeller by a single motor, including a motor output shaft, a driving wheel provided with a second rotating shaft and an impeller provided with a first rotating shaft; a connector is connected between the motor output shaft and the first rotating shaft; and a speed reducer is connected between the connector and the second rotating shaft. The cleaning robot moves forward and backward and makes a turn by the driving wheel, allows wastes to enter an internal filter element under the action of negative pressure generated by the internal impeller, and discharges the purified water or air out of the equipment. The present invention can simultaneously drive the impeller and the driving wheel by using only one motor and can enable the driving wheel and the impeller to generate different rotating speeds.
