[0025] The working principle of this specific implementation is as follows: the power supply voltage of the vehicle electric mouse is DC12V, and the power supply is connected to the car battery.

If there is vibration during operation, the vibration switch LIB1 will work, and the buzzer, ultrasonic wave and high voltage will stop working immediately. After waiting for 60 seconds (the time will be reset if there is vibration during the waiting process), the buzzer, ultrasonic wave and high voltage will resume and start working again at the same time; when the power is turned on or the vibration is restored after waiting for one minute, the white light LED-W will flash three times while the red light LED-R is on, or the white light LED-W will flash six times when the mouse touches the high voltage board, and will not flash at other times. When the mouse touches the high voltage metal sheet 9 of the high voltage board 8, the white light LED-W will flash six times. The mouse will feel pain when touching the metal high voltage board, and will flee in fear of the flashing white light, thus being repelled.

[0026] This specific implementation method connects the high-voltage positive and negative electrodes to a high-voltage board composed of two metal sheets, which makes mice that touch the high-voltage board feel painful and flee. At the same time, the 12kHz-25kHz mouse ultrasonic frequency and the light that are emitted in a loop will also make the mice feel scared due to nerve and visual confusion and stay away, thereby effectively driving away the mice. The driving effect is good, the operation is easy, and it has broad market application prospects.
