The opening and closing device in this embodiment is a normally closed solenoid valve 2131. The outlet of the one-way valve 2132 is directed towards the tank so that air in the pump chamber can enter the tank 211, whereas air in the tank 211 cannot enter the pump chamber 11. A screen 2133 is installed at the interface of the suction pipe 213 and the pump chamber 11 to reduce the possibility of impurities entering the normally closed solenoid valve 2131 and the check valve 2132.
