A fire fighting nozzle is provided, which makes the particle of the water minute and remarkably reduces use of the water. A fire fighting nozzle comprises: a fire hose connection coupling(1) to which the fire hose is connected; a water path(2) for injecting the water to the water charge pipe and sending the water; an air hose(22) connected to the air gun adhered to the fire fighting nozzle bottom part; an air gun trigger(20) which is operated to send the air or the inert gas of the high pressure; air pipes(16,14) sending the air out through the air interception nozzle; a pneumatic piston(17) which pushes the water block cover if the air reaches the air pipe; and a nozzle hole.
