Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a spraying device, which disperses contents evenly in a short time by misting in a space where the circulation with outside air is cut off, such as a closed room. At the same time, it is also possible to uniformly adhere the contents to the surfaces of articles existing within the space.

Conventional spraying devices include aerosol products that spray in space, but because the spray particles have a large diameter and the content stays in the air for a short time, they can be sprayed at a location within the space.
It was difficult to disperse the false particles throughout the space. In addition, to partially achieve this type of purpose, smoke is generated by ignition or chemical reaction, and this smoke contains insecticidal ingredients,
There were some methods that attempted to kill insects in space, but they had the disadvantage that ignition, chemical reactions, etc. were dangerous, and they could not be used for anything other than extremely limited purposes such as insecticidal action. The present invention eliminates the above-mentioned drawbacks, lengthens the residence time of the mist particles in a certain space, makes it possible to uniformly disperse the contents of the mist, and has a moth effect, an anti-rust effect, and It is designed to achieve various purposes such as surface fertilizer effect.

In the present invention, by filling the pressure container with 15 wt% or more of carbon dioxide gas in a liquefied state together with the main spray agent, it is possible to significantly increase the pressure inside the pressure container compared to conventional aerosol products. By minimizing the particle size of the spray contents and lengthening the spatial residence time, it becomes possible to enhance the diffusion effect of the spray particles. The internal pressure of this pressure-resistant container is determined by the filling ratio of liquefied carbon dioxide gas and solvent into the pressure-resistant container, and the relationship varies depending on the type of solvent, but as an example, it corresponds to the filling ratio of kerosene and ethanol to carbon dioxide gas. The pressure inside the pressure vessel is as shown in FIG. Although the particle size of the atomized contents varies depending on the content processing method, pressure, etc., by filling 15 wt% or more of liquefied carbon dioxide into a pressure-resistant container together with the contents, it is possible to During injection, liquefied carbon dioxide gas is also injected at the same time, and the rapid expansion of this injected liquefied carbon dioxide produces a strong crushing effect.
An ideal ultra-small particle size can be obtained. This miniaturization of particle fleas allows the particles to stay in the air for a long time, allowing the contents to spread better in spaces where circulation with the outside air is blocked, such as indoors, and is used in insecticides, treetop odorants, foliar fertilizers, etc. In case,
It is possible for floor mist particles to easily penetrate into areas with air circulation, such as gaps, drawers, and the inside between the hollyhock surfaces, ensuring a reliable insecticidal effect.
It can produce a deodorizing effect. In addition, if the rust-preventing lubricant is used as the content and atomized under pressure with liquefied carbon dioxide gas, the rust-preventing lubricant that has become particles can adhere to the outer surface of the object regardless of its unevenness, curvature, etc. , it becomes possible to perform rust prevention treatment on a large number of articles located in a closed space at the same time. Furthermore, if the foliar fertilizer is sprayed in a greenhouse, the fertilizer can be applied uniformly to the leaves of the plants. By minimizing the spray particles as described above, it becomes possible to achieve various purposes.

In addition, it is safe because there is no ignition or chemical reaction when the contents are exposed to space fog, and the contents such as chemicals and rust preventive agents that are impermeable to ignition or chemical reactions can be effectively eliminated from space fog. It is something that can be done. Example 1: Insecticide nozzle diameter: 0.30 Spraying time: 60°F Spraying completed at 2 $ec.False particle fleas distribution As shown in Figure 2: Example 2: Insecticide nozzle diameter: 0.3°Misting time: 60° False mist particle size distribution, complete in 25 EC Example 3 as shown in Figure 3 Insecticide false aperture 0.40 Fly fog time 60 Flea spray completed in 1 sec False mist particle distribution Example as shown in Figure 4 4 Deodorizer counterfeit caliber 0.30 Spraying time 30 degrees spraying completed at 1 $ec Light mist particle distribution as shown in Figure 5 Example 5 Rust-preventing lubricant counterfeit diameter 0.50 30 degrees fog time 50 degrees As shown in Figure 6, the spray particle diameter distribution in the first to fifth embodiments was measured by attaching smoke generated by burning magnesium oxide to a glass plate. The Korokiri nozzle is located at an interval of 15 skins from the plate, and a shielding plate with a small opening □ is placed between the glass plate and the Akebono nozzle, and the shielding plate is quickly moved into the Korokiri from the Korokiri/Zuru. The forged particles that momentarily passed through the barrier were deposited on a glass plate, and the traces of the deposits were magnified and measured using a microscope or a photograph.
