Description

Multi purpose spraying device {MULTIPURPOSE SPRAY DEVICE}

The present invention relates to a multipurpose injector, and more particularly, to a multipurpose injector used for injecting a mixture beneficial to the skin of the human body to the skin.

Until now, there are many kinds of spraying apparatuses for supplying liquids such as cosmetics, medicines, colorings, etc., but these spraying apparatuses are mainly used in areas such as painting, art, and tattoos.

Recently, there is an increasing demand for an injection device that utilizes basic makeup materials, color materials, and the like as women's makeup by using compressed air or carbon dioxide discharge power. In general, it is well known that a carbon dioxide bath is good for health and beauty in the case of an injection device using a carbon dioxide discharge power. However, the carbon dioxide gas is absorbed into the skin well because oxygen permeability of the cell membrane is about 25 times higher than that of oxygen. This is because it increases the increase.

The effects of carbon dioxide are known as vasodilating effect, anti-inflammatory effect, vascular fluidity improving effect, bore effect (oxygen parallel effect) and the like. In addition, by using the percutaneous absorption effect of carbon dioxide gas to obtain a whitening effect and skin care effect to soften the texture, the development of such an injection device is being actively made.

The compressed air or carbon dioxide gas is injected by mixing with the basic cosmetic liquid and the like by the injection device, the injection device according to an embodiment of the prior art is integral with the main body or the housing portion is coupled to the liquid container that stores the basic cosmetic liquid, etc. It is formed.

When using the injection device, it is necessary to replace or clean the parts of the portion where the liquid container is coupled. In the prior art, the parts to which the liquid container is coupled are formed integrally with the main body, and so on. There was a lot of inconvenience.

And the injection device according to an embodiment of the prior art controls the flow of liquid and gas in two stages of operation.

That is, since the flow of liquid and gas is controlled by pressing and rotating operations, it is difficult to operate and control of the flow is not easy. In addition, there is a disadvantage that the liquid and gas leakage during use because there is no control function of the gas.

Furthermore, one embodiment of the prior art has a disadvantage in that the spraying shape at the tip of the nozzle of the spraying device has a straight or local spraying shape, so that the spraying effect of the liquid mixture is insufficient and the spraying of the liquid mixture is not uniform.

And one embodiment of the prior art is a structure in which a part of the main body of the injection device in which the liquid container is integrated can be disassembled and assembled from the main body, but the used liquid cannot be reused. There is discomfort.

In particular, since the axis of the nozzle and the liquid container are assembled on the same axis, the liquid is exposed to the nozzle, which may cause oxidation or deterioration when left for a long time.
