Control device of exhaust valve

[0025] The invention provides a control device for an exhaust valve, which is used to control the movement of the valve cover of the exhaust valve, thereby opening or closing the exhaust valve. The device includes a power supply, a control circuit, a motor and a mechanical part, and the power supply supplies power to the motor, In order to make the motor drive the mechanical part to move, so that the mechanical part drives the valve cover to move; when the mechanical part moves to a fixed position in a certain direction, the mechanical part triggers the control circuit, and the control circuit controls the power supply to continue to supply power to the motor for a period of time and then power off.

[0026] Wherein, before the control circuit is triggered by the mechanical part, the power supply charges the control circuit, and after the control circuit is triggered by the mechanical part, it discharges, so that the power supply continues to supply power to the motor until the con
