Abstract

Disclosed is an air pumping gun, using an small electric motor driven by a fixed power source or a batter to drive a gear train. The end driven gear of the gear train is loose fitted to a main shaft which is provided with a fix connected driving disc and coupled with one face of the driven gear by a ball clutch. Another face of the driven gear is connected to a pressure adjusting spring exerting a back pressure, which can be adjusted through an knob, on the ball clutch. The end of the main shaft is formed into a crank connected with a connecting rod by a crank pin and the connecting rod is connected with a piston provided in a fixed cylinder by a connecting rod pin. In addition, a pre-pressurized spring is provided between the cylinder and the connecting rod, of which the pulling force can help the piston pressurize air in a labor-saving manner while reciprocating in the cylinder, reduce the vibration resulted from the operation, and make the distribution of piston pressure more even. By driving the main shaft through the driving disc, the piston can reciprocate in the cylinder and press the air outputting through the opening at the front end of the cylinder to complete the pumping operation. Once the pressure of the output end exceeds the preset value, the resulted stress will cause the ball clutch to disengage and end driven gear of the gear train to idle, so as to avoid excessive pumping operation.
