Patent ID: 8353467

Claim:
A fluid spraying gun, comprising: a gripping portion, on which a rotatable lever is provided; an open/close portion which opens and closes a supply path of gas from a gas supply source, through rotation of the lever; a flow separation portion, which separates the flow of gas which has passed through the open/close portion in an open state into a forward flow portion and a downward flow portion; a tube-shape guide, the diameter of which gradually expands toward a front end thereof, and which has a ring-shape front end portion on which a brush extending forward is implanted; a nozzle, which is formed of a flexible pipe member with a front end thereof as a free end, and sprays one portion of gas, which is supplied from the forward flow portion and passes through the nozzle, toward the brush from the front end thereof, while the nozzle undergoes the gyrating motion guided by the tube-shape guide; a flow rate adjustment portion, which has an operating portion, and adjusts the flow rate of another portion of gas supplied from the downward flow portion, in accordance with operation input to the operation portion; an inner nozzle, which sprays gas from a tip thereof, the gas having passed through the downward flow portion; and a liquid distribution pipe, which penetrates the tube-shape guide, links an inside of the tube-shape guide with a liquid supply source, has an intermediate portion into which the inner nozzle is inserted in a state where the inner nozzle is directed toward the tube-shape guide, and draws up liquid from the liquid supply source by a negative pressure arising from spraying of gas by the inner nozzle to cause spraying of liquid on the inside of the tube-shape guide.
