Claims

[Scope of utility model registration request]

A cylindrical nozzle case with a protrusion at the tip is attached to the inner surface of the main body case, which is attached to the mounting holes made in the tank wall at both ends and the circulation pipe installed outside the tank, and the air injection pipe is attached at the required location. The nozzle case is screwed together so that it can move forward and backward, and the hollow part of the nozzle case serves as a secondary flow path that also serves as a mixing chamber for mixing air with the circulating water jetted from the primary side of the flow path, and the nozzle case has a hole in the tank at the tip. The air bubble jetting nozzle is disposed in a bubble jetting nozzle that spouts a foaming jet toward the target, and an annular groove is carved in the rear part, and an air supply hole is bored in the bottom of the groove, and the air supply hole is adjacent to the rear end of the annular groove and the main body case. A valve portion that adjusts communication between the air injection pipe and the air supply hole while slidingly contacting the inner peripheral surface is integrally provided, a valve seat that forms a throttle valve together with the valve portion is provided behind the valve portion, and the valve A bubble flow spouting fitting characterized in that the seat is disposed at a position where the valve opening is maximum when the front end of the valve portion and the rear end of the opening of the air injection pipe are located on the same line.
