Abstract
An inflator includes a mouthpiece, an adjustment mechanism, and an air cylinder mechanism that includes a large-diameter cylinder permitted to move relative to the mouthpiece. When the large-diameter cylinder is moved away from the mouthpiece, air from external environment is sucked into a first space of the air cylinder mechanism. The adjustment mechanism is operable to switch between a pressure relief state, where air in the first space is released to the external environment when the large-diameter cylinder is moved toward the mouthpiece, and a sealed state, where the air in the first space is injected into the mouthpiece when the large-diameter cylinder is moved toward the mouthpiece.
