Claim 6:
7. The bidirectional vent valve according to claim 1, wherein the bidirectional vent valve further comprises:
a mounting seat, wherein the mounting seat is movably disposed on the valve seat, and a pressure relief duct is provided on the mounting seat;
a third valve plate, wherein the third valve plate is fixed onto the valve seat and is located at the second end of the gas duct, and the third valve plate is configured to open or close the pressure relief duct through movement of the valve seat relative to the mounting seat;
a second elastic component, configured to exert a force on the third valve plate to close the pressure relief duct, wherein, when an air pressure at the first end of the gas duct is greater than an air pressure at the second end and the air pressure difference reaches a second threshold, the third valve plate is configured to overcome the force of the second elastic component to open the pressure relief duct,
wherein, the second threshold is greater than the first threshold.
