Claims

[Scope of utility model registration request]

A foam nozzle shell that foams and emits fire extinguishing liquid, a main nozzle hole that is formed along the axial direction of this foam nozzle body and that spouts fire extinguishing liquid, and a space i in the circumferential direction surrounding the main nozzle hole. a plurality of sub nozzle holes which are arranged along the main nozzle hole and eject fire extinguishing liquid; a truncated cone-shaped throttle tapered surface serving as an inner diameter, and the flow of the extinguishing liquid from the sub-nozzle hole is caused to collide with the throttle taper surface and to be displaced toward the axis, so that the extinguishing liquid flows from the main nozzle hole. A fire extinguishing foam nozzle characterized by merging with the flow of fire extinguishing liquid.
