Background Currently, an ultrasonic beauty instrument is used as a non-invasive skin treatment device, and the core technology of the ultrasonic beauty instrument depends on an ultrasonic focus generated by an ultrasonic transducer to act on deep skin tissues, so that the beauty effects of tightening, lifting and the like are realized through a thermal effect. In order to improve the nursing efficiency, a skin treatment device (taking an ultrasonic beauty instrument as an example) in the prior art generally adopts a motor to drive an ultrasonic transducer to move along a preset track (such as rotating or translating around an axis) at a set speed in combination with a transmission assembly, so that the coverage area of an ultrasonic focus is enlarged, and the dotting time of single nursing is shortened. However, in the actual use of the existing ultrasonic beauty instrument, abnormal rotation speed of the motor may occur, for example, the rotation speed of the motor is lower than the set rotation speed, or the motor is blocked (i.e. the rotation speed is 0). When the rotating speed of the motor is lower than the set rotating speed, the acting time of the ultrasonic transducer on the same position of the skin can be prolonged, and when the motor is blocked, the ultrasonic transducer stops moving to continuously act on the same position of the skin, and the two abnormal conditions can cause skin or deep tissue burn or scald, so that the existing ultrasonic beauty instrument has potential safety hazards.
