After a human body contacts the cutter head mesh enclosure 100 and the distributed capacitance of the human body is squeezed, the capacitance accessed by the touch pin of the main control chip IC1 is changed, so that the main control chip IC1 is automatically awakened to stop the sleep mode to start running an output control program. The sixth pin of the main control chip IC1 outputs a high level, the first MOS transistor Q1 is turned on after being connected to the high level, the first MOS transistor Q1 is turned on, the motor 500 is connected to the power supply for starting, the motor 500 starts to rotate for shaving, and meanwhile, the pin of the main control chip IC1 connected to the light emitting diode LED outputs the high level to drive the light emitting diode LED to light up, so that the indicating module 800 is in a normal working state. When the shaving device leaves a human body, the distributed capacitance of the touch pin of the main control chip IC1 is restored to be close to the original value, after the main control chip IC1 detects that the distributed capacitance of the human body changes, the cutter head mesh enclosure 100 is judged to be not in contact with the human body, after the time delay set by a program, the main control chip IC1 outputs a low level, the first MOS tube Q1 is cut off, the motor 500 stops rotating, the light emitting diode LED is turned off, the main control chip IC1 automatically returns to a power-saving sleep mode, and the intelligent on-off function of the shaving device is achieved. With the voltage reduction of the power module 700, the voltage output from the main control chip IC1 to the light emitting diode LED is also reduced, and then the light emitting diode LED gradually becomes dark, and it can be known whether the electric quantity of the power module 700 is approximately changed and the electric power is insufficient through the brightness of the light emitting diode LED, when the voltage output from the power module 700 is lower than the lowest working voltage of the main control chip IC1, the main control chip IC1 cannot normally work, at this time, the cutter head mesh enclosure 100 contacts with the human body, the device cannot be started, the light emitting diode LED cannot be lighted, and the user is prompted to replace the dry power module 700 or recharge the power module 700. If the LED can be normally turned on but the motor 500 does not rotate after the cutter head mesh enclosure 100 is touched, it is determined that the cutter head on the device is clogged with impurities or the motor 500 fails, and at this time, the user should clean up the impurities accumulated between the cutter head and the cutter head mesh enclosure 100 in time, so as to determine whether the motor 500 normally operates according to the rotation between the LED and the motor 500.
