Description

Portable Air Brush {A PORTABLE AIR BRUSH}

The present invention relates to a portable airbrush, and more particularly, to a portable airbrush with an improved structure to stably prevent leakage of the solution remaining inside the cartridge after use of the airbrush that sprays the solution in a mist state. About.

In general, lotion is a transparent liquid cosmetic used for moisturizing, astringent, nutrition, soothing, whitening, wrinkle improvement, hair care, etc. after washing the face or hair.

This lotion is prepared as a liquid with a transparent appearance by solubilizing a water-soluble substance and stabilizing it thermodynamically.

On the other hand, recently, in the process of manufacturing a lotion, technologies such as microemulsion and lipid nanospare are employed.Using these technologies, a little oil component is emulsified and the specific gravity of the oil phase and the aqueous phase is adjusted to allow creaming or sedimentation even at low viscosity. A lotion is sometimes made in a translucent or opaque shape where the back does not occur.

These lotions are applied directly to the skin or hair at body temperature and are used.Since the lotion used in this way is not effective in penetration of the active ingredient into the skin, it is effective by covering a towel moistened with hot water after using the lotion. There is a hassle such as assisting the penetration of ingredients.

In addition, since the lotion is a low-viscosity liquid, there is a problem that it is difficult to spread evenly on the skin or hair.

Therefore, it was used by spraying the lotion in a mist state so that the active ingredient contained in the lotion can be evenly adsorbed and effectively penetrated into the facial skin or hair.

Such a device for spraying the lotion in a mist state is generally referred to as an air brush, and the structure and principle of mist generation of such an air brush are very diverse.

Meanwhile, FIG. 1 is a view showing a part of an injection structure of a conventional airbrush.

Referring to (A) and (B) of FIG. 1, the conventional airbrush is inserted and supported in a form in which the needle 20 is movable inside the nozzle 10. The needle 20 advances or retreats with respect to the injection direction inside the nozzle 10 to flow out or block the injection solution. As the needle 20 moves, it contacts the nozzle 10 to block the flow path of the spray solution.

However, since both the nozzle 10 and the needle 20 are made of metal, abrasion may occur between the nozzle 10 and the needle 20 due to frequent use for a long time, and a gap 30 may be formed therebetween. In this case, if the solution remains inside the cartridge without using the airbrush, there is a concern that the solution may leak into the nozzle 10 through the gap 30.

The nozzle cap 245 protects the nozzle 243 and may form a compressed air flow path 270 between the nozzle 243 and eject compressed air flowing out along the compressed air flow path 270.

In one embodiment, the nozzle 243 may form a coupling groove (243a) for coupling with the leak preventing portion 250, as shown enlarged in Figure 4, the leak preventing portion 250 is a coupling groove ( 243a) can be combined in the form of a force fit.

The leak prevention part 250 is interposed between the needle 231 and the nozzle 243, so that when the needle 231 blocks the injection solution, it is in close contact with the stepped 231a of the needle 231 to prevent leakage of the injection solution. have. The leak prevention part 250 may be made of a silicon packing, and the coupling protrusion 250a may be coupled to the coupling groove 243a of the nozzle 243 in a form of force fitting. The leak prevention part 250 is coupled to the nozzle 243 to prevent abrasion between the needle 231 and the nozzle 243 due to the movement of the needle 231 and prevent solution leakage. The leakage preventing unit 250 is coupled to the nozzle 243 at the front end of the injection hole 241 from which the solution is ejected, and one side of the needle 231 is inserted into the nozzle 243 to advance toward the injection hole 241 When moving to, it is in close contact with the stepped jaws 231a of the needle 231 to maintain airtightness.

When the user does not use the airbrush 100, one side of the needle 231 moves forward in the spray solution flow path 260 as shown in FIG. 4 to close the spray solution flow path 260. At this time, the stepped jaw 231a of the needle 231 is in close contact with the exposure preventing unit 250 to maintain airtightness. Accordingly, even if the solution remains in the cartridge and is discharged through the solution discharge port 210, it is possible to prevent leakage toward the nozzle 243. That is, when the air brush 100 is not used, compressed air is not ejected from the main body 110, and the injection solution flow path 260 is closed by the needle 231 in close contact with the leakage preventing unit 250. Since the solution remains in the cartridge, the solution does not leak to the nozzle 243 and is prevented from leaking to the outside.

FIG. 5 is a longitudinal sectional view showing the injection head when the airbrush in FIG. 3 is in operation, and FIG. 6 is an enlarged view of a portion indicated by “B” in FIG. 5.

The airbrush 100 is operated if it is moved in the direction in which it is moved. In one embodiment, when the injection button 123 is moved downward, the movable member 237 is pressed and rotated.

In this process, the needle guide 233 slides toward the other side of the needle 231, that is, in the opposite direction of the injection hole 241.

The elastic member 235 is compressed by the sliding movement of the needle guide 233, and one side of the needle 231 retreats from the injection liquid flow path 260 and the injection hole 241, as shown enlarged in FIG. The spray solution accommodated in the cartridge is discharged through the solution discharge port 210 by opening the space between the prevention unit 250 and the spray solution flow path 260 that is opened. The discharged spray solution is dispersed by compressed air and sprayed to the outside of the spray head 120 through the spray hole 241 in the form of a mist.

Conversely, when the user releases the force applied to the injection button 123, the shape of the elastic member 235 is restored by the elastic force of the elastic member 235, and the needle 231 advances to prevent leakage as shown in FIG. It is in close contact with the unit 250 to maintain airtightness, and the operation of the airbrush 100 is stopped.

The portable airbrush according to an exemplary embodiment maintains airtightness between the needle and the nozzle even if the solution remains in the cartridge after use to prevent leakage of the solution, so that it can be easily stored or carried and used hygienically.
