The present invention is achieved by providing an air gun for cleaning which rapidly ejects compressed air to generate a shock wave. The air gun for cleaning is an air gun for cleaning which is formed in an easily gripped handgun-like shape and includes a main body with a passage penetrating between front and rear ends, wherein a straw for ejecting the compressed air and a compressed air supply pipe are connected at the front and rear ends of the main body, and an open/close structure, which is disposed at the center of the passage and is manipulated by a trigger to enable/disable the ejection of the compressed air while opening and closing the passage, is provided on a middle portion of the passage. The air gun for cleaning further comprises: a piston-type actuator which is installed in a traverse direction to the passage of the main body, appears and disappears by an open/close manipulation of the trigger, and includes a connection path for controlling a flow of the compressed air according to a relative alignment between the passage and the connection path, and a closing surface; a control element, which is screw-assembled at an end of the actuator to appear and disappear and adjusts a stroke distance of the actuator for opening and closing the passage according to the manipulation of the trigger; and a recovery element, which is installed at a rear end of the actuator to recover the actuator to an original position, such that an ejection amount of the compressed air is freely adjusted. |
