Portable Cosmetic Sprayer Using Compressed Air

The present invention relates to a cosmetic liquid spraying device, and more particularly, to a portable cosmetic liquid spraying device having a pressure spraying method that can be used neatly without leakage and has no independent parts such as a lid and is convenient to manage.

Cosmetics used for beauty are directly applied to the skin, so they have a sensitive effect on skin health. Therefore, high-end cosmetics tend to be preferred.

Recently, there are many women who suffer from skin problems due to problems of the environment, diet, or stress. As part of this, the importance of skin care is increasing, and accordingly, various types of cosmetics or skin protectants have been proposed on the market.

The present invention is in a liquid form, and cosmetics have been developed to simultaneously obtain the effects of moisturizing, skin beauty, and skin health by applying directly to the skin. These liquid cosmetics are applied to the skin through a cosmetic spraying device that sprays them on the face in the form of fine particles in order to increase skin absorption. Some cosmetic injection devices have a built-in small compressor that generates air pressure. This reduces the consumption of cosmetics by allowing the cosmetics to be sprayed together with compressed air and helps to increase the effect of use of cosmetics by atomizing them. In general, liquid cosmetics containing active ingredients beneficial to health are supplied to the skin through this cosmetic spraying device.

In the conventional cosmetic supply device, one or two drops of liquid leaked during use, which was inconvenient to use. In particular, in order to take out cosmetics from the sealed cosmetic capsule, an air hole is provided, and leakage occurs frequently through the air hole. When cosmetics leak, foreign substances sometimes get on them, the cosmetics are consumed, and sometimes they get on other items in the handbag.

In addition, as disclosed in Korean Patent Application No. 10-2017-0023673, a cap that must be separated from the body when used is often included, and in this case, it is inconvenient to manage the cap. That is, there is the inconvenience of using the cap every time it is used, and having to close the cap again after use.
