The cleaning assembly driving device 200 in this embodiment can be used to drive the cleaning assembly 300 first so that the cleaning assembly 300 can rotate or reciprocate relative to the working surface to clean the working surface.

Referring to fig. 2 to 7, in order to reduce the risk of the cleaning assembly 300 getting stuck or caught and to prevent secondary pollution, the cleaning assembly driving device 200 of the present embodiment mainly includes a first supporting member 1, a moving block 2, a first driving motor 3, a first transmission assembly 4, and an output shaft 5.

7. The cleaning assembly drive of claim 1, wherein the first drive assembly includes an eccentric drivingly coupled to the power output of the first drive motor and a drive arm having one end drivingly coupled to the power output of the eccentric and another end connected to the moving mass;

the first driving motor drives the eccentric wheel to rotate, the transmission arm is driven to move forwards or backwards along a first direction, and the moving block moves forwards or backwards along the first direction relative to the guide mechanism.

8. The cleaning assembly drive of claim 7 further comprising a trigger switch disposed opposite the front of the actuator arm, the trigger switch configured to: when the first driving motor drives the moving block to advance along with the transmission arm in a first direction, so that the suspension part is suspended at the first end of the sliding rail, the transmission arm triggers the touch switch to disconnect the power supply of the first driving motor.

9. The cleaning assembly drive of any one of claims 1-8 further comprising a second drive motor and a second transmission assembly, wherein the second transmission assembly is drivingly coupled between the second drive motor and the output shaft, and wherein the second drive motor is configured to drive the output shaft for rotation by driving the second transmission assembly to rotate the cleaning assembly attached to the first end of the output shaft.

10. The cleaning assembly drive of claim 9 further comprising a second support member disposed relatively below said first support member, said first support member covering said second support member and defining a receiving chamber therebetween; at least the first driving motor, the second driving motor and the second transmission assembly are contained in the containing cavity; the first end of the output shaft is exposed from the lower surface of the second support member, and the cleaning assembly is connected to the first end of the output shaft outside the accommodating cavity.

11. A cleaning robot comprising a cleaning assembly drive as claimed in any one of claims 1 to 10.
