The upper shell, the middle shell, the lower shell and the air cavity are integrated into an integrated assembly. The air cavity includes a cylinder head. A ventilation plate is arranged on the outside of the cylinder head. When pumping, the gas pushes up one side of the ventilation plate from the air inlet hole of the cylinder head.
