PURPOSE: A impact type air jet fog nozzle is provided to control pressure of an air jet which faces a high pressure liquid jet, thereby preventing bending or abrasion of an impact fin. CONSTITUTION: An impact type air jet fog nozzle comprises a main body(10), an orifice(20), an air-jet feeding part and a second air jet feed port. The orifice is penetrated into the inside of the main body and guides the sprayed liquid jet. A first air jet feed port brings a corpuscle liquid jet discharged through the orifice to collide with a high pressure air jet in order to perform primary atomization. A second air jet feed port brings the first atomized fluid to collide with the high pressure air jet and additionally performs atomization and spray direction control. The first air jet feed port comprises an air-jet flowing pipe(32) and a first pumping area(34). The second air jet feed port comprises an assistant air-jet(42) and a second pumping area(44).
