Description

[Detailed description of the invention] In a sprayer having a nozzle that sprays in a horizontal direction, if the nozzle is of a multi-hole type, the mist tends to be dense and light, which tends to cause uneven spray results.

Therefore, in this proposal, the mist is applied to the blades and dispersed by rotating the rotary impeller using the spray pressure.
The aim is to reduce the unevenness of the fog and improve its distribution.

Next, an embodiment of the present invention shown in the drawings will be described.

In the figure, 1 is a spray head main body of a spray machine, and the main body 1, which is arranged almost vertically in use, includes a connecting part 2 to a spray machine (not shown) and an automatic valve using water pressure. 3 and a liquid passage 4 are formed, and each of the liquid passages 4 extends in a substantially horizontal direction (that is, a direction perpendicular to the direction in which the spray head main body 1 is disposed) through a plurality of pores 5. The nozzles 6 are opened radially with respect to the spray head main body 1 at approximately equal angular intervals.

Below the nozzle 6, the spray head main body 1 rotatably supports a rotary impeller 7, the axis of rotation of which is aligned with the axis of the spray head main body 1.

A plurality of blades 8 are attached to the rotary impeller 7, with which the mist sprayed from the nozzle 6 collides. The receiving surface 8' of each blade 8 is angled with respect to the direction of the spray from the nozzle 6 so that when the mist from the nozzle 6 collides, a force is generated to rotate the rotary impeller 7 in one direction. It is to be set up and admonished.

As a result of the above configuration, the nozzle 6 as shown by the dashed arrow in the figure.
When the spray is generated, the pressure of the spray acts on the blades 8, causing the rotary impeller 7 to rotate at high speed.

In this way, as a result of the rotary impeller 7 rotating at high speed,
This time, conversely, the mist from the nozzle 6 is dispersed by the blades 8, and the overall spray can be averaged in each direction.

In this case, in order to increase the rotational inertia of the rotary impeller 7, the member 9 that reduces resistance must be connected to the rotary impeller 7 and the receiving washer 1.
It is best to insert it between 0 and 0.

Normally, with a nozzle that sprays horizontally, the mist does not come directly below the nozzle, but according to the structure of the present invention, the mist that hits the blade 8 loses velocity energy, falls directly below, and travels far away. Fog distribution will be better regardless of distance or short distance.

In addition, to explain the structure and function of the above-mentioned automatic valve 3 using water pressure, the valve body 12 is seated on the valve seat 11 formed in the middle of the passage 4 leading to the connection part 2 in the spray head main body 1,
A piston-shaped split wall body 14 that slides in an air-water tight manner within a cylindrical body 13 that is integrally formed with the main body 1 is integrated with the valve body 12, and is arranged on the upstream side of the valve seat 11, that is, on the side of the connecting portion 2. The force of a spring 15 facing the passage 4 and loaded on the valve body 12 presses the valve body 12 against the valve seat 11. Modifiable and adjustable.

Note that 17 is an air vent. In the automatic valve having the above-mentioned configuration, when a set hydraulic pressure is applied to the screw-type split wall body 14, the valve body 12 separates from the valve seat 11 and guides the liquid to be sprayed to the nozzle 6, causing the liquid to be sprayed. When the pressure drops below the spray set pressure, the force of the spring 15 instantly presses the valve body 12 against the valve seat 11, cutting off the supply of liquid.
