ように噴口６に取付けて使用される（第９図参照）。(Prior art) As the orifice 1 of the nozzle suitable for generating fine mist,
Conventionally, as shown in FIGS. 6 to 8, an orifice plate 2 having a diametrically long bulge 3 formed in the center thereof and an orifice hole 4 provided in the center of the bulge 3 has been used. ing. This orifice hole 4 is made by punching a rectangular hole in the center of the orifice plate 2, forming a diametrically long bulge 3 around the hole, and further extending the bulge 3 in the longitudinal direction. The protruding portion 5 is formed by squeezing the upper portions of both side surfaces and raising the central portion. Therefore, when viewed in cross section in the width direction of the bulging portion 3, the orifice hole 4 has a tapered shape that expands toward the bulging side, as shown in FIG. The orifice 1 described above is used by being attached to the nozzle 6 so that the bulging portion 3 faces outward (see FIG. 9).

。As shown in FIG. 10, the spray pattern ejected from the nozzle 6 with the orifice 1 installed as described above is composed of a portion of fine mist 7 that expands in the direction of expansion of the orifice hole 4, and a portion of relatively large particles around it. There is a part where mist 8 exists in the origin, and thin streaks 9 appear on the furthest sides. The expansion angle θ1 of the part of the fine mist 7 is such that the punch dimensions of the orifice hole 4 (the size of the hole when punching in a flat plate state) are 0.3 m in length and 0.4 m in width.
m, water pressure of 15 kg/c, the temperature is about 18 degrees.
細霧を必要とする噴霧２＝（例えば夏季においてビニー

均等に分散することが望ましいわけであるが、従来の場
合は、拡散角が小さく、また大粒の霧８の部分が存在し
たり、細い霧の筋９が生じるなど、均等性にも欠けると
いう問題があった。For spraying 2 = that requires a fine mist (for example, when spraying water into a plastic greenhouse to lower the temperature in the greenhouse in summer), it is desirable that the fine mist be dispersed as widely and evenly as possible. However, in the conventional case, there were problems in that the diffusion angle was small, and the uniformity was also lacking, such as the presence of large fog particles 8 and thin fog streaks 9.
そこで、この発明はこれらの問題点を解決し、細霧の拡
散性及び均等性に優れた噴口を提供することを目的とす
る。SUMMARY OF THE INVENTION It is an object of the present invention to solve these problems and provide a nozzle with excellent mist dispersibility and uniformity.
