Claims

[Scope of utility model registration request]

A tubular base is attached to the end of the hose that sends the extinguishing liquid, and the first, first and second tubes are spaced apart from each other inside this base.
The second orifice is fixed, and the flow path area of the two orifices is set such that the flow path area of the second orifice on the downstream side is two-thirds that of the first orifice on the upstream side. A foaming nozzle for a fire extinguisher, which is constructed by connecting a mixing tube that changes the flow path of fire extinguishing liquid ejected from a central throttle opening, and having a through hole drilled in a portion of the mixing tube near the throttle opening.
