Abstract:
An airbrush comprising a barrel, said barrel comprising a transversely extended through hole, an air valve mounted in the through hole of said barrel at a bottom side, said air valve comprising an air hole, a piston rod adapted to close/open the air hole of said air valve, and spring means adapted to force said piston rod to close the air hole of said air valve, a nozzle head fastened to a front end of said barrel, a nozzle cap fastened to said nozzle head to hold a nozzle tip, a needle holder mounted in said barrel and axially moved in said barrel, a needle fastened to said needle holder and moved with said needle holder to close/open a paint passage through said nozzle head and said nozzle tip, a spring cap fastened to a rear end of said needle holder, a spring mounted in said spring cap to support said needle holder in a front position where said needle closes the paint passage, and a fluid cup fastened to said barrel and adapted to provide a paint to said nozzle head for enabling the pair to be forced out of said nozzle tip by compressed air passing from said air valve, and a main lever mounted in the through hole of said barrel at a top side and adapted to move said piston rod in opening the air hole of said air valve and to simultaneously move said needle holder and said needle in opening said paint passage, wherein said main lever comprises a through hole for the passing of said needle, a push rod stopped at a front end of said needle holder, and an arched bottom recess, which receives a spherical top end of said piston rod for enabling said main lever to be turned on said spherical top end of said piston rod to push said needle barrel backwards in opening said pain passage after said main lever had been pressed to move said piston rod downwards in opening the air hole of said air valve.
