Description

[Detailed description of the invention] This invention relates to an insect-proof humidifying device for greenhouse cultivation, and is designed to prevent insects and maintain humidity in the greenhouse, and to prevent sudden changes in the greenhouse temperature when spraying insect repellent.

In greenhouse cultivation, the indoor humidity is kept constant at all times, making it easy for pests to appear, and since the greenhouse is isolated from the outside with glass or plastic cloth, the humidity must be kept constant.

Sprayers conventionally used to spray insect repellents and maintain humidity are equipped with a blower pipe in contact with the outlet of the spray pipe that sucks up the insect repellent or water in the tank, and the air pressure from the blower pipe blows the tank There are some that suck up the chemical solution in the tank and spray it in the form of a mist, and others that apply air pressure to the tank and spray the chemical solution or water in the form of a spray.

However, since these sprayers are devices that suck up or force out the liquid in the tank through the spray pipe, in addition to the fact that suspended particles in the tank may clog the outlet of the spray pipe, mist particles may Because the fog particles are large, there is a disadvantage that when spraying insect repellent or insecticide, the chemical does not reach the underside of the leaves.Furthermore, since the mist particles are large, there are disadvantages such as the indoor temperature dropping rapidly when spraying chemical solutions or humidifying. .

The present invention is intended to solve the above-mentioned drawbacks, and an embodiment thereof will be explained with reference to the drawings. Reference numeral 1 denotes a sprayer, and the sprayer includes a spherical hollow air pressure bulb 2 and an air supply pipe connected to the air pressure bulb 2. 3, a mounting plate 4 through which the air pipe 3 passes, and a diffusion method 5 erected on the mounting plate.

6 is a small exhaust hole opened on the outer periphery that intersects with the virtual horizontal plane passing through the center of the air pressure bulb 2, and in the diffusion method 5, the center of the ball is a straight line connecting the center of the air pressure ball 2 and the center of the small exhaust hole 6. located above,
And there is a slight gap (for example, 3 to 4 spaces) 8 between the air pressure bulb 2 and the air pressure bulb 2.
Set on the mounting plate 4 with the

The position where the small exhaust hole 6 is opened is not limited to the above-mentioned part, but as described later, when the chemical solution is dropped from the top of the air pressure bulb 2 to the outer circumferential surface, the coating is thinnest on the iron part, so When air is blown out from a small exhaust hole, the finest mist can be generated, so it is best to install it in an iron part.

The above is an example in which the air pressure bulb has one small exhaust hole 6, but as shown in the plan view of FIG. It is also possible to form a sprayer by opening a plurality of exhaust holes 6 in the bulb 2 and setting the same number of diffusion methods as the exhaust holes 6 in opposing parts of the exhaust holes 6.

Reference numeral 9 denotes a funnel-shaped spray valley surface, in which the atomizer 1 is set, the air supply pipe 3 is connected to a compressor 11 outside the atomizer surface via a pipe 10, and the outlet 12 of the spray dense surface 9 is connected to the compressor 11 outside the atomizer surface. The return pipe 13 is connected to the chemical tank 14, the suction side of the suction pump 15 is connected to the chemical tank 14, the discharge side is connected to the pipe 16, and the discharge port 11 of the pipe 16 is fixed close to the upper center point of the air pressure method 2. A spray hose 18 of a required length is set on the diffusion bulb 5 side of the spray dense surface 9.

In the above device, when air pressure is sent from the compressor 11 to the air pressure method 2, the air pressure is strongly ejected from the small exhaust hole 6, collides with the diffusion bulb 5, and is diffused in all directions.

Next, the suction pump 15 is operated and the discharge port 17 of the pipe 16 is
When a liquid such as an insect repellent is dropped, the liquid descends as a liquid film along the spherical surface of the atmospheric pressure method 2, and the liquid that flows down near the small exhaust hole 6 is blown out from the small exhaust hole 6 due to the atmospheric pressure. ), the particles are released into the small exhaust hole, and together with the air pressure, they turn into a mist of very small particles and collide with the diffusion bulb 5. Due to the collision, the mist particles are further divided into small mist and dispersed. The chemical solution is sprayed into the room from the spray hose 18 due to the air pressure ejected from the small exhaust hole, and the chemical liquid that flows down from the air pressure method 2 is returned to the return pipe 1.
3, it is reduced to the chemical liquid Kunk 14.

To maintain indoor humidity, connect pipe 16 to chemical liquid Kunk 1.
Although not shown in the drawings from 4, if the water is transferred to a fresh water tank and the suction pump 15 is operated, a mist of ultrafine particles can be sprayed in the same manner as in the case of spraying a chemical solution.

That is, since the sprayer 1 in this device atomizes the liquid dropped on the surface of the air pressure sphere using the air pressure ejected using the air pressure method, there is no risk of the spray pipe becoming clogged as with conventional sprayers, and there is no risk of the spray pipe clogging using the air pressure method (0).
The mist that is atomized through the small exhaust hole 6 is further collided with the diffusion bulb and broken down, so that the size of the mist particles is approximately constant and becomes a mist of extremely fine particles. It adheres to the underside of leaves, improving its insect repellent and killing effects.

In addition, since the mist particles are extremely fine, they are effective in preventing the indoor temperature from dropping rapidly when spraying chemical solutions or spraying mist to maintain humidity.
This is a useful idea for greenhouse cultivation.
