Abstract
A multifunctional air gun, designed to be operable in a sucking mode, a blowing mode or a sucking and blowing mode, is disclosed. In the air gun, a tubular body has an on/off valve unit in addition to upper and lower openings communicating with each other. A fixed spool is set within the upper opening of the tubular body and connects the air supply tube to an air jet pipe while controlling the flowing direction of compressed air. A vacuum valve unit is set within the lower opening of the tubular body and is assembled with suction and exhaust nozzles at both ends while allowing the two nozzles to communicate with each other. The vacuum valve unit vacuumizes the interior of the two nozzles due to the compressed air. A first control knob is assembled with the fixed spool to control the compressed air for the vacuum valve unit, thus controlling the suction force generated by the compressed air for the vacuum valve unit. A second control knob is assembled with the fixed spool to control the compressed air for the air jet pipe while controlling the blowing force generated by the compressed air for the air jet pipe.
