Abstract

A gas switching device incudes a valve body, a switching assembly, and a manipulating member. The valve body has an inlet portion having an inlet passage and an outlet portion having an outlet port and a receiving chamber. A wall of the receiving chamber has a side opening communicating with the inlet passage. The switching assembly includes a plug member located in the receiving chamber. The manipulating member is detachably connected to the outlet port via the connecting end connected to the plug member, and a gas passage of the connecting end communicates with an axial hole of the plug member. The manipulating member drives the plug member to turn between a first position that an outer peripheral surface of the plug member closes the side opening and a second position that the through hole communicates with the side opening.
