Claims

[Claims for Utility Model Registration] 1. A central body having a tapered air-water mixing chamber formed therein, a fountain nozzle body attached to the central body such that a nozzle opening is located within the air-water mixing chamber, An air diffuser comprising: an air introduction path opened near the nozzle opening of the fountain nozzle body; and an air diffuser plate disposed on the exit side of the air/water mixing chamber so as to block the air/water mixing chamber. 2. Utility Model Registration The device according to claim 1, wherein the air diffuser plate is a flat plate that is perpendicular to the streamline of the air-water mixed flow.
