ABSTRACT:
An air nozzle for an automatically inflatable air cushion includes a mounting seat, a connecting pipe having a first end mounted on the mounting seat and a second end formed with a passage connected to the mounting seat, a control valve including a valve body movably mounted on the connecting pipe and a valve cap mounted on the valve body and provided with a protruding seal portion that is movable to seal the passage, and an elastic member to push the seal portion outwardly relative to the passage. Thus, the air nozzle can be locked quickly and exactly to interrupt the air flow to prevent the air flow from being returned into the automatically inflatable air cushion.
