p X Q X v (H: Collision force, p: Specific mass, Q:
Flow rate (■: flow velocity), and a force equivalent to the collision force H acts on the nozzle as a reaction force of the jetted water (the problem that the invention aims to solve). It simply converts the pressure energy of the fluid into velocity energy by reducing the cross-sectional area of the fluid, and its cleaning power is also limited, making it difficult to remove dirt from places such as depressions, and the cleaning area (spraying area) is also narrow. Furthermore, although it is possible to increase the impact force of the jet water by increasing the water pressure, as mentioned above, the same reaction force is applied to the nozzle, and the jet water bounces back significantly. .

It is an object of the present invention to provide a nozzle that can obtain a wide spray area and also reduce recoil related to the nozzle.

その商品価値は険めて高い。(Effects of the Invention) As explained above, according to the present invention, in addition to the strong collision force of the jet water jetted from the direct nozzle, the jet water is jetted while the nozzle body rotates, resulting in higher cleaning power and Not only can it remove stubborn dirt, but it can also remove dirt that has settled even in hard-to-reach places and crevices. Furthermore, the rotation radius is large, so it has a wider cleaning pattern (wider) than a flat spray (fan-shaped) nozzle. Cleaning area) and cleaning time can be significantly shortened, and unlike conventional nozzles, the impact force of the jetted water does not directly become a reaction force.
The reaction force related to the nozzle is divided and the reaction force behind the nozzle is weakened, so the effort required by the cleaning operator (supporting force of the nozzle, etc.)
It has great effects such as reducing water spray and dirt splashing.
Its product value is extremely high.
