Claims

[Scope of utility model registration request]

The inlet passage into which the air-water mixture is introduced has at least one hole extending from the bottom opening of the columnar nozzle body to the inside of the nozzle body along the axis of the nozzle body to near the top surface of the nozzle body. The nozzle body is formed as a linear injection hole at the bottom, and is provided in the vicinity of the intersection except for the intersection with the axis of the injection hole on the top surface of the nozzle body, which is formed as one plane approximately perpendicular to the axis of the injection hole. A notched sloped surface is formed from the ridge line to the other side of the nozzle body that slopes from the top surface to the bottom surface, corresponding to each of the injection holes, and furthermore, on the respective types of sloped surface. A concave groove having a figure 7 cross section with a constant depth and running longitudinally along an inclined line approximately perpendicular to the dividing ridge line at a position on at least one side that is set at a certain distance from the axis of the corresponding injection hole. The bottom of the concave groove and the top of the injection hole communicate with each other to open a discharge port, and the air-water mixture is introduced under high pressure into the inlet channel opened at the bottom of the nozzle body. A spray nozzle characterized in that a substantially uniform atomized mist is sprayed from the discharge port at the top of the spray hole through the groove to the front of the top surface of the nozzle body within a certain range.
