a reciprocating engaging mechanism adapted to constrain a movement of the cover relative to the housing, the reciprocating engaging mechanism comprising:
a shaft disposed on the cover;
a rotary plate rotatably disposed on the shaft;
a first engaging component;
a second engaging component disposed on the housing; and
a linkage module, an end of the linkage module being connected to the rotary plate in a rotatable manner, rotation of the rotary plate driving the linkage module to move and switch the first engaging component between a locking mode and an unlocking mode, so as to tightly shelter the housing by the cover for preventing the gaseous matter inside the housing from leakage.
