The present invention relates to a device for spraying paraffin wax, and more particularly, to a spray gun capable of dissolving and spraying paraffin wax.

Recently, as interest in beauty, skin care, and the like grows into a social phenomenon, new beauty instruments or beauty therapies are being developed in response to such social demands.

Among these, paraffin therapy is used for skin care in skin care rooms or for physical therapy in orthopedic surgery, and the demand is gradually increasing.

Paraffin wax refers to a colorless or white, slightly translucent and hard wax consisting of a mixture of straight chain hydrocarbons having a melting point of about 48 ° C. to 66 ° C. Recently, however, paraffin waxes are also being developed that melt at lower temperatures than the normal melting point. Candles are a kind of paraffin wax, but paraffin wax, which is used on the skin, is used to reduce oil content as much as possible. In addition, if necessary, it is applied to the skin by containing an oil having various functions.

Paraffin therapy is to dissolve the paraffin wax by heating to an appropriate temperature to apply to the skin of the subject to discharge the waste accumulated on the skin with sweat by the warmth and thermal conductivity of paraffin. In addition to the discharge of waste products, paraffin therapy is known to have a moisturizing effect that moisturizes dry skin and removes dead skin cells from the skin surface.

An example of a device used to perform such paraffin therapy is 'Korean Registered Utility Model No. 20-0345499', 'far infrared amputee physiotherapy device' (hereinafter referred to as 'prior art').

The far-infrared amputee physiotherapy apparatus according to the prior art has a container with heating means. Paraffin wax for skin care is put into the container and heated to dissolve the paraffin. After that, soak your hands or feet and take them out to dry in the air.

However, since the device according to the prior art contains paraffin in a small container, it is possible to directly apply paraffin by soaking only hands or feet, and using a method such as applying paraffin on a wide body part by brush or the like has a cumbersome surface. . In addition, it was used to soak hands or feet rather than the amount directly applied to the skin, which was discarded afterwards. In the case of reusing the paraffin, which was once used to recycle it, there was an unsanitary shave due to keratin or sweat coming off the skin.

As to solve the above problems,

An object of the present invention is to provide a means for dissolving the paraffin in the amount of the paraffin so as to directly spray on the skin instead of immersing the paraffin in the dissolved paraffin in order to coat the paraffin on the skin.

In addition, an object of the present invention is to form a device used for the injection of the paraffin smaller than the device according to the prior art and to improve the ease of treatment by enabling the direct use in the body parts to be treated paraffin therapy.

In order to achieve the above technical problem, the present invention,

A spray having a container, a trigger, an air passage, an injection liquid passage, an air control unit connected to the trigger to open and close the air passage and the injection liquid passage, and an air nozzle and an injection liquid nozzle to which air and injection liquid are injected, respectively. In matters,

The vessel is provided with a heating unit for heating the contents contained in the vessel above the melting point.

Meanwhile, the container and the spray passage may be formed of a material having high thermal conductivity.

With reference to the accompanying drawings will be described a preferred embodiment of the present invention. Unless otherwise defined or mentioned, terms indicating directions such as 'up, down, left and right' used in the present description are based on the states indicated in the drawings.

Paraffin spray gun according to the present invention can be broadly divided into the configuration of the container 10, the spray gun and the air compressor (not shown) having the heat transfer unit 11 as a whole.

Spray guns and air compressors (not shown) are generally identical in configuration to those used in conventional spray guns. Conventional spray guns are classified into various types according to the paint supply method and the location where the paint and air are mixed.

Spray guns are generally divided into suction type, gravity type and pressure type according to the paint supply method.

The suction type draws the paint by vacuuming the front of the air cap by the pressure of the air in such a manner that the container is installed under the spray gun.

Gravity type is a method in which the container is attached to the upper part and the content of the container reaches the injection liquid nozzle by gravity applied to the content in the container. Compared to the suction type, the gravity applied to the contents is added to the spraying force. It is also advantageous in that it can be ejected to the end of the contents.

On the other hand, the feed type is provided with a separate container and direct pressure on the spray liquid in the container to send to the nozzle of the spray gun. Since the spray gun does not have a container, the gun is easy to operate and a large amount of paint can be easily used at a time, so it is usually used when painting a large area.

On the other hand, spray guns are classified into internal and external spray guns according to where the mixture of the spray liquid and the air is made.

The internal mixing formula refers to a method in which the compressed air and the injection liquid are mixed inside the air cap 23. External mixing is a method commonly used as a spray gun in which compressed air and paint are mixed outside the air cap 23.

Preferred embodiments according to the present invention include externally mixed and gravity spray guns.

With reference to FIG. 1, the structure by the preferable Example of this invention is demonstrated.

The gravity spray gun according to the present invention is an air passage 21, an injection liquid passage 31, a trigger 40, a needle 32, an air control unit 22, an air nozzle 20, and an injection liquid nozzle 30. The main configuration is.

The air passage 21 is formed from the lower part of the spray gun to the air nozzle 20 at the left end through which air is injected. Inside the handle portion of the spray gun, an air adjusting portion 22 supported by a spring blocks the air passage 21.

The injection liquid passage 31 is connected to the lower part of the container 10 installed on the upper part of the spray gun, and is formed up to the injection liquid nozzle 30 formed at the left end of the spray gun through which the contents of the container 10 are sprayed. It is also blocked by the needle 32 which is supported by the spring. The injection liquid passage 31 is generally formed by cutting the inside of the body of the spray gun to form a passage, but the tube 10 is formed by forming a pipe separately from a material having high thermal conductivity such as aluminum alloy and inserting it into the passage formed in the body. When heated, it is preferable to receive heat from the container 10 so that the temperature can be heated similarly to the container 10.

When the user adjusts the air control unit 22 and the trigger hook unit 33 by the spring and pulls the trigger 40, it is pushed to the right while receiving elasticity by the spring. The needle 32 is connected to the left end of the trigger hook portion 33.

The container 10 is installed on the upper portion of the spray gun, and the lower portion of the container 10 is connected to the injection liquid passage 31 so that contents can flow into the injection liquid passage 31. The container 10 is preferably made of a material having high thermal conductivity such as aluminum alloy so that the contents of the container 10 can be easily heated when heated.

Outside the vessel 10 is provided with an electrothermal heating portion 11 surrounding the vessel 10 to heat the vessel 10 to a predetermined temperature or more.

Electric heating methods include resistance heating, arc heating, high frequency heating and infrared heating. Among them, resistance heating is a method of heating using Joule's heat generated by the resistance of the object when current flows through the object. Electric heating devices such as electric irons, rice cookers, electric blankets, and coffee pots used at home use resistance heating. Resistance heating is efficiently obtained a high temperature, there is a feature that can control the temperature freely.

In the embodiment of the present invention, a resistance heating method is preferably used. It is also possible to use a nichrome wire or iron chromium wire used when heating to a temperature below 1,000 ° C as a heating element (coil) and attach a separate sensor (not shown) to maintain or limit the container to a specific temperature during heating. However, it is preferably limited so as not to be heated above a certain temperature by using a PTC element as a heating element.

PTC device is an abbreviation of Positive Temperature Coefficient and refers to a device whose resistance increases as the temperature increases. In other words, when the temperature is low, the current flows a lot, and the device itself becomes hot. On the other hand, when the temperature rises above a certain level, the resistance of the device increases, the current flowing decreases and the amount of heat generated by the device decreases. For example, in many cases, the electronic mosquito scent that is frequently used in summer is adopted by heating with PTC element. At this time, the limiting temperature for blocking the current of the PTC device is formed between approximately 50 ° C. and 80 ° C., although somewhat different depending on the characteristics of the device.

On the other hand, the electrothermal heating part 11 is wrapped in a heat insulating portion 12 formed of a low thermal conductivity material so as not to be exposed.

Paraffin wax has a melting point of 45 degrees to 65 degrees as described above is common, and recently, paraffin wax has been developed that the melting point is formed even at a temperature of 45 ℃ or less. On the other hand, when the human body is exposed to a temperature of 60 ° C. or higher, a first degree burn is caused. Therefore, even when the temperature is dropped while the injection liquid is injected, it is preferable that the heat-heating unit 11 is not heated to a maximum of about 65 degrees or more. On the other hand, in order to dry the paraffin wax sprayed on the human body, the melting point of the paraffin wax should be formed above the temperature of each part of the human body to which the paraffin wax is applied. Therefore, paraffin wax is used having a melting point of approximately 36 ℃ or more.

Therefore, the electrothermal heating unit 11 preferably heats the container 10 at 36 ° C. or higher but cuts off the current at 65 ° C. or lower by using a PTC element having a high resistance at 65 ° C. or lower.

On the other hand, the handle of the spray gun is finished using a synthetic resin having the properties of insulation and insulation to protect the user's hand from the power supplied to the heating element 11 and the heat generated from the heating element (11). .

On the other hand, as shown in [FIG. 3], the trigger hook portion 33 can be put a little play from the portion that the trigger 40 and the trigger hook portion 33 is caught. Even when the trigger 40 is pulled, the needle 11 connected to the trigger hook part 33 and the trigger hook part 33 retreats to the right only after the trigger 40 is pulled by a predetermined angle or more due to the play.

The operation of the preferred embodiment of the present invention will be described with reference to FIG. 2.

When the container 10 is heated above the melting point of the contents (mainly cosmetic paraffin wax) by the heat transfer part 11, the contents inside the container 10 are melted. The liquid content flows into the injection liquid passage 31 through the lower portion of the container 10 and reaches the injection liquid nozzle 30.

When the user retracts the trigger 40, the air adjusting unit 22 and the needle 32 retreat to the right, and the air passage 21 and the injection liquid passage 31 are opened. As the air passage 21 is opened, the high pressure air compressed by the air compressor (not shown) is injected through the air inlet 24, and is injected through the air nozzle 20 through the air passage 21.

Due to the air that is rapidly injected through the air nozzle 20, the front portion of the air cap 23 is the pressure drops. The contents are ejected through the injection liquid nozzle 30 by the low pressure portion formed in the front portion of the air cap 23 and the gravity of the contents contained in the container 10. The contents injected through the injection liquid nozzle 30 are mixed with the air injected through the air nozzle 20, atomized, and directed to the target object.

The user performs paraffin therapy by drying the area where the contents are applied in air and removing it after a certain time.

On the other hand, referring to Figure 3, as described in the configuration of the preferred embodiment of the present invention, if the length of the trigger hook portion 33 is formed to be a short play from the trigger 40, pull the trigger 40 When the air control unit 22 and the trigger hanger 33 is caught by the trigger 40, the starting point is different. That is, when the user pulls the trigger 40, initially only the trigger hook part 33 is retracted to inject air, and after the trigger 40 is retracted to the right by a predetermined angle or more, the trigger hook part ( 33) is also caught by the trigger 40 to start the retreat and the contents contained in the container 10 is also sprayed together. In other words, the user has a play between the trigger hook portion 33 and the trigger 40 for quick drying after applying paraffin wax to the user's skin, or to shake off dirt such as dust attached to the skin before applying the paraffin wax. By pulling the trigger 40 within the range, only air can be injected.

Although the preferred embodiment of the present invention has been described above, the technical idea of the present invention is not limited to the above-described preferred embodiment, and various heating means are provided in a range not departing from the technical idea of the present invention specified in the claims. Can be implemented with a spray gun.

From the above structural features,

Paraffin spray gun according to the present invention has the convenience that can be paraffin therapy by spraying paraffin in any part of the body, regardless of the size or size as needed.

In addition, the paraffin spray gun according to the present invention can be used by dissolving the amount of paraffin necessary for the procedure to prevent waste of paraffin, and thus there is no need to recycle the paraffin, thereby enabling hygienic paraffin therapy.

In addition, the paraffin spray gun according to the present invention has a high convenience because of its small size, so that it is more easily handled and can be used near the treatment site.

In addition, the paraffin spray gun according to the present invention is configured to have a predetermined clearance from the trigger part so that only air can be sprayed for cleaning the skin or for quick drying of the applied paraffin.
