摘要： The present invention relates to an air injection device. The air injection device includes: a body having an air passage formed therein; and an opening and closing part coupled to one end periphery of the body and having an opening and closing protrusion protruding from an inner surface thereof toward the air passage of the body by a given length in such a manner as to open and close the air passage, wherein the opening and closing protrusion is moved in a first direction toward the body or in a second direction opposite to the first direction by means of a user's control for the opening and closing part, and the movement of the opening and closing protrusion in the first direction or in the second direction is guided by means of a guide groove formed on an outer peripheral surface of one end portion of the body and a guide protrusion formed on the inner peripheral surface of the opening and closing part in such a manner as to be inserted into the guide groove.
