Claims

[Claims for Utility Model Registration] 1. A concave hole having a dome-shaped concave surface is provided in the nozzle main body in a rearward open state, and the front end of the nozzle main body has a relatively deep groove with a letter-shaped cross section, an inverted trapezoid,
A relatively shallow groove with a wide bottom, such as a rectangular or U-shaped cross section, is carved into a synthetic groove obtained by overlapping the bottoms of both grooves back and forth at an appropriate angle, intersecting the concave surface. A distribution control type fan-shaped spray nozzle characterized by forming a nozzle approximately in the shape of a boat bottom. 2. A concave hole having a semicylindrical concave surface is provided in the nozzle main body in a rearward open state, and the front end of the nozzle main body has a relatively deep groove with a V-shaped cross section and a wide groove with an inverted trapezoid, square, U-shaped cross section, etc. A relatively shallow groove with a bottom and a synthetic groove obtained by overlapping the bottoms of both grooves back and forth at an appropriate angle are carved perpendicularly to the semicylindrical concave surface to form a substantially boat bottom. A distribution control fan-shaped spray nozzle characterized by having a shaped nozzle.
