Description

Ultrasonic atomizer and spraying method using the same

The present invention relates to an ultrasonic nebulizer and a spraying method using the same, and more particularly, to an apparatus and spraying method for remixing and spraying cosmetic ingredients stored in a state in which contact with oxygen is blocked using ultrasonic waves.

Sunscreen is a generic term for products that function to protect the skin from the sun's ultraviolet (UV) rays. Sunscreen is also called sunscreen, and generally refers to a sunblock in the cosmetic group.

Sunscreens are classified into inorganic (physical), organic (chemical), and mixed sunscreens. Inorganic tea has a white turbidity phenomenon, and it tends to have poor application properties compared to organic or mixed tea. It has a slightly oily feel and has good adhesion, so you need to thoroughly clean it. It has a UV protection effect right after application and is characterized by being the mildest to the skin.

The representative components of inorganic cars are titanium dioxide and zinc oxide. Organic tea does not have white turbidity, absorbs well and gives a refreshing feeling. It takes time to take effect, and there may be eye irritation. Organic tea ingredients can interfere with the skin regeneration of troubled skin, and children with sensitive skin are discouraged from using it, and it is characterized by being easily removed by water and sweat.

Representative ingredients of organic tea include ethylhexyl methoxycinmate, benzophenone-3 (oxybenzone), avobenzone, octylmeroxycinnamate, ethylhexyl salicylate, and homosalilate.

Mixed tea is a mixture of inorganic and organic components, and it is common to mix ethyl hexylcinmamate with zinc oxide, and there are cases where both inorganic and organic components are included. As a characteristic, an immediate effect appears and there is no cloudiness.

Among the types of sunscreen, most of the sunblocks released for commercialization use inorganic ingredients because of the disadvantage that the chemical action of organic sunscreens can harm the skin.

According to the commercialized form of the sunscreen, it has different characteristics in application convenience, portability, blocking effect, and oily feeling. If sunscreens are classified by product form, they can be classified into sun cream, sun stick, sun cushion, and sun spray.

Sunspray has the function of spraying sunscreen in the form of a mist. Sunspray is easy to use all over the body, can be sprayed on the desired area, and is easy to wipe off. Nevertheless, sunspray is pointed out as a disadvantage in that it is difficult to apply uniformly and control the amount of spraying. And the disadvantage pointed out in all types of products is that the shelf life is short due to the mixing of the emulsifier component with titanium dioxide and zinc oxide.

The mist supply, which can be used in a wider range than sunspray, can be used for liquid cosmetics containing an aqueous solution according to the user's purpose of use, such as lotion, moisturizing, whitening effect, and nutrient supply. It refers to a device that ejects into a state.

Such a mist supply includes a steam heating type mist supply that is used in a stationary manner, including a manual spray type mist supply that has been widely used in the past.

However, the existing manual spray type mist feeder has the inconvenience that the user has to repeatedly press the button to operate it, as well as the principle of dispersing the liquid using only the discharge pressure discharged through the fine jet hole, There is a problem in that the size of the fine particles of the liquid is relatively large, and it is difficult to spray it as it is uniformly dispersed.

On the other hand, the steam heating type mist supplyer uses a spray method that heats the liquid to atomize the liquid in a steam form, and has the advantage that it is possible to spray the liquid in the form of relatively small and uniform particles, but it is difficult to drive the heating device. In order to do this, relatively large power is required, so it is impossible to carry the device because the size of the device is large.

As a technology related to the present invention, the Republic of Korea Patent Publication discloses a portable liquid cosmetic electric mist supply comprising a storage container, a pump, an ultrasonic vibration means and a bucket, but the liquid cosmetic in the storage container is discharged using a pump. It is distinguished from the configuration of the present invention in which the contents are discharged using the high-pressure gas in the pressure vessel in this respect.
