Referring to fig. 1, a schematic view of a circuit configuration of an electric shaver, a schematic view of an external appearance of an electric shaver, fig. 2, a schematic view of an internal configuration of an electric shaver, fig. 3, and a top view of a head of an electric shaver, fig. 4, the electric shaver including a body 10 and a head 20 which are interconnected; the body 10 includes a housing 110, a control chip 120 and a driving part 130 disposed in the housing 110, and a handle sensing element 140 disposed on the housing 110, and the cutter head 20 includes a head sensing element 210; the control chip 120 is connected to the driving part 130, the handle sensing element 140 and the head sensing element 210, respectively, and the driving part 130 is further connected to the cutter head 20.

The handle sensing element 140 is disposed at a handle position (a position gripped by a hand) of the body 10, and is configured to sense a first sensing signal generated when skin approaches and transmit the first sensing signal to the control chip 120; the head sensing element 210 is used for generating a second sensing signal when sensing that the skin approaches and sending the second sensing signal to the control chip 120; the control chip 120 is configured to send a driving control signal to the driving part 130 when receiving the first sensing signal and the second sensing signal, so that the driving part 130 drives the tool bit 20 to work.

In addition, the control chip 120 is further configured to send a closing control signal to the driving member 130 when the first sensing signal and the second sensing signal are not received or only one of the first sensing signal and the second sensing signal is received during the operation of the cutter head 20, so that the driving member 130 stops driving the cutter head 20. Thus, the automatic shutdown function of the electric shaver is realized, and the electric energy can be saved.

Specifically, the material of the housing 110 may be, but is not limited to, plastic. The control chip 120 may be an MCU (micro controller Unit). For example, the control chip 120 is a single chip microcomputer, and the model of the control chip 120 may be, but is not limited to, PL51T 020. One or more than one cutting head 20 may be provided, for example, two or three cutting heads 20 may be provided, and the number of the cutting heads 20 is not limited in this embodiment. The control chip 120 may be connected to the driving part 130, the handle sensing element 140, and the head sensing element 210 through transmission conductors (transmission lines), respectively.
