Description

Portable Air Brush {A PORTABLE AIR BRUSH}

The present invention relates to a portable airbrush technology, and more particularly, it is possible to prevent the solution contained in the storage container from flowing backward through the air hole of the airbrush that sprays the solution contained in the storage container in a mist state. It relates to a portable airbrush that improves the structure of the airbrush so that it is convenient to carry and store.

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 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, the lotion was converted into a mist so that the active ingredient contained in the lotion could be evenly adsorbed and effectively penetrated into the skin or hair of the face. This mist refers to particulates contained in a gas, is composed of very small liquid particles floating in the air, and has a particle size of 0.1-100μ.

On the other hand, a device that generates mist through an air injection method is generally referred to as an airbrush, and the structure and principle of mist generation of such an airbrush are very diverse.

For example, Korean Patent Application Publication No. 10-1530424 (2015.06.15) relates to an airbrush, which discharges compressed air when the battery and power are supplied, and allows the power of the battery to be supplied or cut off to the air supply means. An air supply module equipped with a switch, a storage tank in which the injection liquid is stored, and a needle valve and a needle valve that allow the injection liquid contained in the storage tank to flow out or block through the outlet hole arranged in the injection hole, and the supply flow passage through which compressed air flows And a valve frame arranged adjacent to the outlet hole and formed with an orifice portion through which compressed air passing through the air supply passage is ejected in the direction of the injection hole, and a trigger for simultaneously operating needle valves and switches, and an injection hole is formed on one side and separated from the supply module. An airbrush for spraying a spray liquid in a mist state including a spray head that is possibly coupled is disclosed.

As another example, Korean Patent Publication No. 10-2046089 (2019.11.12) relates to a portable mist device, a case in which an air supply device is provided, an ampoule detachably provided on the upper part of the case, and A connecting member that is provided with an air supply device located at the bottom and an ampoule provided at the top to receive compressed air and beauty water, and a person who is provided at the front end of the connecting member and sprays beauty water in a mist state by compressed air It is made of sand and generates mist through the air injection method, but it is possible to stably spray mist by directly generating compressed air, and when not in use, it is possible to stably prevent leakage of the lotion contained in the ampoule provided removably. A portable mist device is disclosed.

On the other hand, in the conventional air brush, an injection port for injecting the injection liquid is formed on the upper side of the injection liquid storage container, and the injection hole cover has a ventilation hole that allows external air to flow into the storage container for smooth flow of the injection liquid. Will be formed.

However, when the airbrush is carried and moved while the spray liquid remains inside the storage container, there is a risk that the spray liquid flows backward through the ventilation hole and leaks to the outside.

The main body 110 may include a battery that supplies power therein, and may be installed so that a charging lamp 111 indicating a state of charge of the battery is exposed to the outer periphery. The charging lamp 111 is lit while the battery of the main body 110 is being charged, so that the user can identify that the battery is currently being charged. The main body 110 includes an air pump and a motor therein, and when driving force is transmitted to the air pump, it may suck the surrounding air to generate compressed air. At this time, when the motor is supplied with power, it may generate a driving force.

Here, the main body 110 and the injection head 120 may be detachably coupled to each other.

The spray head 120 may have a spray hole 121 formed on one side thereof, and a storage container 123 in which a spray solution is stored at an upper side of the spray hole 121. In one embodiment, the spray head 120 sprays the spray solution accommodated in the storage container 123 in the direction of the spray hole 121, and at this time, the compressed air discharged from the main body 110 is ejected to eject the spray solution. It is dispersed by the air current and can be sprayed in the form of mist.

The spray head 120 may have a spray button 125 formed on one side of the storage container 123 so that the airbrush 100 can be operated and stopped only by a user pressing the spray button 125. Here, the injection button 125 may be moved downward along one side of the storage container 123 and then returned to its original state.

The storage container 123 may include a container container 211 and a container lid 213. In one embodiment, the container container 211 and the container lid 213 may be integrally molded or combined in a detachable form. Here, the container container 211 and the container lid 213 may be made of the same material or a material having a different shape.

To this end, the container lid 213 may be provided with an injection port for injecting the spray solution.

The container lid 213 may be coupled to an injection port cover 127 for opening and closing the injection port. The injection port cover 127 may have various structures capable of sealing the injection port. When the user wants to inject the spray solution into the storage container 123, the injection port cover 127 is opened to expose the injection port, and then the spray solution flows into the container container 211 of the storage container 123 through the exposed injection port. You can do it. In one embodiment, the injection port cover 127 may be made of the same material as the container lid 213 or a release material. Here, the injection port cover 127 may be made of a material having elasticity.

The upper side of the storage container 123 may include a backflow prevention part 129 that forms a ventilation hole so that air passes only in a direction toward the inside of the storage container 123. In one embodiment, the backflow prevention part 129 is disposed at the center of the injection port cover 127 and is formed in a one-way valve structure, so that the injection solution accommodated in the storage container 123 flows backward through the vent hole. Can prevent leakage. Here, the backflow prevention part 129 may be formed in a duckbill shape.

The backflow prevention unit 129 prevents vacuum in the storage container 123 by opening the ventilation hole so that outside air flows into the spray liquid receiving space of the storage container 123 when spraying the spray solution, and does not spray the spray solution. If not, that is, when the airbrush 100 is not used, the ventilation hole may be sealed to prevent external leakage of the spray liquid.

The protective cap 130 covers the spray head 120 as a whole and may be detachably coupled to the spray head 120.

2A-2B are perspective views of main parts showing a state in which the injection port cover of the storage container is opened and closed in the injection head of FIG. 1, and FIG. 2A is a state in which the injection port of the storage container 123 is closed with the injection port cover 127, FIG. 2B shows a state in which the injection port of the storage container 123 is open, respectively, and FIG. 3 is a cross-sectional view taken along line A-A' of FIG. 2A.

Referring to FIGS. 2A to 3, the storage container 123 may store a spray solution to be sprayed in the form of a mist using the air brush 100. The storage container 123 is disposed on the upper side of the spray head 120 and may be composed of a container 211 and a container lid 213.

The container container 211 may have an accommodation space in which the spray solution is stored, and an outlet 215 through which the spray solution accommodated in the accommodation space is discharged may be formed at the lower side. The spray solution discharged from the discharge port 215 may flow out in the direction of the spray hole 121 along the flow path in the spray head 120. At the lower side of the container 211, a fastening portion for fastening with the injection head 120 may protrude on both sides of the discharge port 215.

The container lid 213 may be coupled to cover the upper side of the container 211, and an injection port 217 for injecting a spray solution may be formed in the center. The injection hole cover 127 may be installed in the injection hole 217 so as to be open and close. The container lid 213 may have a concave groove 213a on one side of the rim to facilitate the user opening and closing operation of the injection port cover 127.

When the spray solution that has been accommodated in the receiving space in the container container 211 is exhausted, as shown in FIG. 2B, the injection port cover 127 is opened and the injection port 217 is opened, and the spray solution in the container container 211 Can be injected.

In one embodiment, the injection port cover 127 is connected to the opposite side of the position where the concave portion 213a of the container lid 213 is formed, and may be coupled to cover the opening of the injection port 217 and bend to one side. It may be formed so that the coupling with the injection hole 217 is released. Here, the injection port cover 127 may be sealed or released from the injection port 217. The injection port cover 127 has an annular protrusion 127a formed on the lower side, so that the protrusion 127a can be forcibly fitted to the opening of the injection port 217, so that watertightness between the injection port 217 and the injection port cover 127 Structure can be formed. Accordingly, it is possible to prevent the injection solution from leaking between the injection port 217 and the injection port cover 127.

A backflow prevention part 129 may be installed at the center of the injection port cover 127. In one embodiment, the backflow prevention part 129 is a valve that extends to pass through the air hole 311 and the ventilation hole 311 and whose end is sealed or released depending on whether the injection head 120 is injected. A member 313 may be included. Here, the ventilation hole 311 is to allow external air to flow into the spray liquid receiving space of the container container 211. That is, as the air brush 100 is operated and the spray solution accommodated in the storage container 121 flows along the spray solution flow path of the spray head 120, the ventilation hole is equal to the volume of the spray liquid discharged from the storage container 123. This is to allow the spray solution to flow smoothly by allowing external air to flow into the storage container 123 through 311).

The valve member 313 may be formed to be gradually narrower in a planar shape toward the lower side from the annular ventilation hole 311, and a gap 313a in a linear shape may be formed at an end thereof. In one embodiment, the valve member 313 may be formed in a one-way valve structure that passes air introduced through the ventilation hole 311 only in a direction toward the receiving space of the container 211. Here, the valve member 313 may be formed in a duckbill shape.

The duckbill valve is a one-way valve made of rubber and has a structure that gradually narrows from a cylindrical shape to a plane shape, and a discharge port is formed in the plane shape, so that discharge is possible from the discharge port of the cylindrical part to the plane part. , It is a kind of one-way valve in which inflow from the surface-shaped part to the cylindrical part is impossible.

The backflow prevention part 129 according to an embodiment can pass air through the gap 313a of the valve member 313 from the vent hole 311 by applying the structure of the duckbill valve, but conversely, the gap between the valve member 313 It is impossible to pass the solution from (313a) to the ventilation hole (311). The backflow prevention part 129 pressurizes the valve member 313 while passing through the ventilation hole 311 when the spraying liquid is sprayed, so that the gap 313a is opened, and air is passed through the gap 313a. 211) It is introduced into the interior. When the airbrush 100 is not used, the backflow prevention part 129 is pressurized toward the valve member 313 within the container container 211 to close the gap 313a so that the spray solution in the container container 211 is passed through. It is possible to prevent leakage into the pores 311.

4A-4B are cross-sectional views showing the operating state of the backflow prevention unit installed in the storage container in FIG. 1, FIG. 4A is a state of the valve member when the air brush is operated, and FIG. 4B is a state of the valve member when the air brush is stopped. Respectively.

4A and 4B, in order for the user to operate the airbrush 100, the injection button 125 is specified by applying a force to the injection button 125 provided on the top of the injection head 120 in a specific direction. When moving in the direction, the airbrush 100 is operated. In one embodiment, when the injection button 125 is moved in a downward direction along one side of the container 211, the injection head 120 operates a needle disposed under the injection button 125 so that the body 110 The compressed air generated from and the spray solution discharged from the outlet 215 provided at the lower side of the container 211 flow through each flow path to the spray hole 121, and the spray solution and compressed air discharged through the nozzles respectively. It can be ejected and sprayed outside in a mist state.

When the spray liquid is sprayed, the backflow prevention part 129 is a duckbill-shaped valve member 313 extending under the vent hole 311 while air is introduced in the direction of the arrow in FIG. 4A through the vent hole 311. ) Is pressed to open a gap 313a formed at the lower end. Therefore, the lower end of the ventilation hole 311 is opened by the gap 313a that is opened, and the incoming air passes through the opened gap 313a to prevent vacuum in the container container 211 and accommodated in the container container 211 It allows the spray solution to flow smoothly.

When the spray liquid is not sprayed and the airbrush 100 is not used, the backflow prevention unit 129 is the valve member in the direction of the arrow in FIG. 4B because the internal pressure of the container 211 is relatively higher than the external atmospheric pressure. The pressure is applied to 313 so that the gap 313a formed at the lower end of the valve member 313 is collected. Accordingly, the lower end of the vent hole 311 is sealed by the gathered gap 313a to prevent the reverse flow of the spray solution remaining in the container container 211. In this state, even if the user knocks down the airbrush 100, the solution in the container 211 does not leak to the outside.

The portable airbrush according to an embodiment is opened when spraying a solution to prevent vacuum in the storage container, and the structure of a duckbill valve that closes the ventilation hole during storage to prevent leakage during storage, making it easy to store or carry. It can be used hygienically.
