Abstract

An air inflation device includes an inflation unit having a chamber in which air can be compressed to generate a high pressure air, and an air outlet channel communicating with the chamber. A pressure gauge unit includes a pressure gauge, a shaft extending outwardly from the pressure gauge and inserted into the air outlet channel, and a check valve sleeved on the shaft and movable between an open state for allowing the high pressure air in the chamber to flow into the air outlet channel, and a closed state for preventing the high pressure air in the air outlet channel to flow back into the chamber. An air guide unit is connected to the inflation unit for guiding the high pressure air to flow out of the air outlet channel.
