An air inflation device includes an inflation unit defining an interior space, a handgrip unit connected to the inflation unit, and a pressure measuring mechanism disposed in the handgrip unit and including a first tubular member defining a receiving space, and a second tubular member defining a flow guide channel that has an air inlet communicating with the interior space, and an air guide hole communicating with the receiving space. A measuring unit is disposed in the receiving space and has a free end pushed to move relative to the first tubular member by air entering the receiving space from the flow guide channel. An indicating unit indicates a position of the free end in the first tubular member.
