Referring to fig. 10, fig. 10 shows a block diagram of a cleaning robot in the present embodiment, the cleaning robot 600 further includes a detector 630 and a controller 640, wherein the detector 630 is disposed on the housing 610 for detecting the position of the transmission member 400. The controller 640 is disposed in the casing 610 and is electrically connected to the detector 630 and the driving component 620, and the controller 640 controls the driving component 620 according to the position detected by the detector 630. The detector 630 can detect the position of the transmission member 400, and when the transmission member 400 is in the extended or retracted position, the controller 640 controls the second motor 622 of the driving assembly 620 to stop working, so as to avoid causing stalling and affecting the service life. In particular, the detector 630 may be a hall sensor or an infrared sensor.

Further, the transmission member 400 is provided with a limiting portion 440, and the limiting portion 440 may be engaged with the driving assembly 620 to limit the rotation of the transmission member 400. The limiting portion 440 further limits the rotation of the driving member 400, so as to ensure that the cleaning member 220 swings outward to a maximum position, i.e. a side position, when the driving member 620 is interfered.

It will be apparent that the embodiments described above are merely some, but not all, embodiments of the utility model. Based on the embodiments of the present utility model, those skilled in the art may make other different changes or modifications without making any creative effort, which shall fall within the protection scope of the present utility model.
