Description

Injection valve device for aerosol

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an aerosol spray injection valve device, in which a jet propulsion body is rotated by a cyclone shaft installed therein into a jet nozzle, and the jetted jet body and the contents filled in the pressure vessel are rotated and jetted in a jet nozzle of the jet nozzle. It relates to an aerosol spray injection valve device that is ejected to the outside by the pressure of the propellant.

In general, the aerosol spray is composed of a pressure vessel in the shape of an enclosure having an open top, and an injection device that is opened and closed by a push button in the opening of the pressure vessel. The lower end of the injector is equipped with a straw extending into the pressure vessel to guide the contents to the injector. In the pressure vessel of the aerosol spray is filled with the contents according to the intended purpose, the contents are filled with the gas inside to eject the contents through the injector.

In the conventional aerosol spray, a portion of the inner space of the pressure vessel is filled with the packing liquid (the content to be ejected) and the gas, and the remaining space is composed of the expansion space of the gas. The inside of the container maintains a state in which the internal pressure is applied by the vapor pressure of the liquefied petroleum gas. At this time, when the injection device installed in the pressure vessel is operated (opened), the mixture of the crude liquid and the liquefied petroleum gas is simultaneously ejected.

However, the gas filled in the conventional aerosol spray uses a flammable gas that has a harmful effect on the environment, such as liquefied natural gas, butane gas, and the like, there is a risk of fire when the raw liquid is ejected, and due to the release of harmful gas into the atmosphere There was a problem that adversely affects.

In addition, the conventional filling gas is sensitive to temperature, when the temperature is high, there is a risk of explosion, when the temperature is low, there is a problem that the injection force is lowered.

In addition, since it is essential to ensure the safety of the use of liquefied petroleum gas and butane gas, there have been various problems such as the production of a container using only iron or aluminum materials.

In addition, with the development of building technology, such as soundproofing and sealing effect, in the modern living environment where even ventilation is poor. Conventional liquefied petroleum gas (LPG) sprays release large amounts of VOCs into the atmosphere. Pollution of indoor air destroys our indoor environment and harms our health, and secondary problems such as atopic skin diseases caused by invisible petrochemical irritants occur.

In addition, in order to solve the problems of the conventional filling gas, there is a method of ejecting the fluid by air pressure, but when using only the air pressure, there is a problem that the performance of the aerosol spray is lowered because the injection force is lower than the conventional filling gas As a result, there is an urgent need for research to improve this situation.
