Abstract
An air pump device includes a housing having a barrel, a grasping device engaged in the housing for grasping an inflation valve to the housing selectively, a pumping mechanism coupled to the barrel of the housing for generating a pressurized air to the compartment of the housing, and a pressure gauge device engaged within the pumping mechanism for indicating a pressure in the chamber of the barrel and for preventing the pressure gauge device from being exposed. The pumping mechanism includes a tubular member having one end portion coupled to the barrel, and the tubular member includes a space for receiving the pressurized air from the tubular member.
