The main control module 12 starts timing by the signal timing unit 121 when receiving the level signal, until the level signal disappears, that is, the user ends the pressing action. The determining unit 122 determines whether the timing result exceeds a preset timing duration (e.g., 20ms, 30ms, etc.), and if so, the determining unit 122 determines that the level signal is an effective signal, and the pressing operation is effective.

In some embodiments, if the signal timing unit 121 counts the duration of the level signal to 3s (preset lockout duration), the main control unit 124 may control the shaver to enter the lockout state. When the shaver enters the locked state, the motor control module 13 stops driving the external motor 300 until receiving the level signal again for a duration of 3 s.
