Description

[0001] The present invention relates to hair irons and hair irons, and more particularly,

The present invention relates to a hair iron, and more particularly, to an improved hair iron which is capable of perming perming treatment on wet hair as well as dry hair, while preventing damage to hair.

Generally, in the case of permanent surgery, a hair iron is used. Usually, the hair is dried by a hair dryer, and then a hair iron is used to perform the permanent operation.

Such a hair iron may be a so-called " dry hair ", which applies a strong pressing force on both sides to dry hair (hereinafter also referred to as " dry hair ") so as to become a straight permanent, It is a permanent mechanism.

The common feature of such a permanent apparatus such as a hair iron is that the thermal energy of the electric heater built in is transferred to the metal heating plate and the metal heating plate is put in direct contact with the dry hair.

 Since the metal heating plate is usually made of a metal such as aluminum or stainless steel, the metal heating plate has advantages of long life without corrosion such as rust in the adoption of the hair iron, and the heat transfer is relatively good.

However, when a direct heat treatment method in which the hair is directly contacted with the metal heating plate is tried, the medical agent (permanent medicine) applied to the hair is directly contacted with the metal heating plate, which receives heat energy from the electric heater of the hair iron There is a problem that water vapor explosion occurs instantaneously instantaneously, resulting in a water explosion phenomenon, which makes it impossible to perform permanent treatment.

In detail, the metal heating plate receives heat transfer from the electric heater. At this time, the metal has a large thermal conductivity coefficient because heat conduction is performed by free electrons.

As the thermal conductivity coefficient becomes larger as described above, the thermal energy of the electric heater is rapidly transmitted to the surface of the metal heating plate which is in direct contact with the hair.

Therefore, the amount of the medicine to be applied to the hair is very small, but the heat energy of the electric heater is continuously transmitted rapidly to the surface of the metal heating plate, so a minute amount of the medicine is instantaneously heated and the water explosion phenomenon occurs. Or when the medicine is applied, the hair can not be used at all. Only when the hair is completely dried, heat energy can be imparted to the hair.

Therefore, in the conventional state, only the indirect heat treatment method in which heat energy is radiated to the hair by the hair drier, the electric lamp, or the steamer described in the prior art documents in the state where the medicine is applied.

In this case, if the heat energy is continuously radiated to only one place, the heat treatment is performed in such a manner that the heater is radiated while the lamp is continuously rotated, because the medical agent is burned or evaporated.

Therefore, since heat energy can not be uniformly transferred to the entire hair, it causes non-uniform heat treatment, which makes it difficult to perform a good permanent operation and causes staining after dyeing, and it is necessary to radiate heat energy to hair for a long time. There is a problem that it takes a long time.

In the conventional indirect heat treatment method, when the thermal agent is applied, the thermal agent may be evaporated or burned when the thermal energy is radiated to heat the hair. Therefore, the hair has to be heat treated at a relatively middle temperature of 40-50 As a result, when the hair is stretched or the permanent hair is dried, the hair is completely dried and inconveniences and inconvenience are caused to re-perform the operation at a heating temperature of high temperature by using an apparatus such as an electric hair iron.

In addition, it is possible to perform permanent operation only for dry hair even if the operation is repeated with hair iron. Therefore, it is necessary to remove the permanent medicine at the time of permanent operation and then to perform the thermal permanent operation by the hair iron. And the like.

In addition, not only the hair treatment time was long, but also the treatment for imparting high heat energy to the dried hair caused the moisture contained in the hair tissue to evaporate and cause damage.

In detail, conventionally, since permer treatment can be performed only on dried hair, high thermal energy of the metal hair heating member is directly transferred to the dry hair, thereby evaporating the moisture in the fur material. Therefore, the hair is further dried and damaged, It will be further damaged and destroyed.

In the case of women with relatively long hair, the ends of the hair are usually gathered together. Therefore, if the hair is allowed to dry in the dry hair state, the moisture contained in the constituents of the fur material evaporates. As a result, the hair becomes stiff or brittle . ≪ / RTI >

Therefore, conventionally, in the case of permanent surgery, it is necessary to thoroughly check the state of hair health and perform permanent surgery, and it is difficult to expect a good permanent in a novice or a home, thereby causing a raise in the cost of permanent surgery in a beauty shop.

The most serious disadvantage is that conventional hair irons can only perform permanent operations on dried hair, so even if the skilled person is skilled, the hair can not be damaged.

Therefore, the applicant has made a hair iron which is entirely covered with a rubber layer entirely at the front end of the hair iron, thereby preventing the occurrence of trouble and sealing the heating part, as disclosed in Korean Patent No. 10-0905499.

However, the above-mentioned prior art is disadvantageous in that the hair is not slipped smoothly due to the high coefficient of friction due to the material properties of the rubber, although the front end of the hair iron is entirely covered with the rubber layer,

Therefore, when the permanent operation such as pulling the hair iron in contact with the dried hair is performed, the hair does not come out easily or is not released, so that it is very difficult to perform the permanent operation and in case of severe case, Even serious cases have been caused.

That is, when the hair is heated by the metal heating member in the related art, it is impossible to perform the wet permanent operation due to the water explosion phenomenon and the hair is damaged. The hair iron developed by the present applicant can perform the wet permanent operation without damaging the hair The hair did not slip well, so dry permanent surgery was difficult.

It is an object of the present invention to provide an improved hair iron which is capable of both dry and wet permanent operation without damaging the hair.

It is a further object of the present invention to allow non-skilled persons to perform permanent surgery well without damaging the hair.

The present invention provides a hair iron having at least one hair heating unit having a handle portion having a circuit portion therein and a metal heating member heated by a heater for applying heat energy to the hair in front of the handle portion, A rubber layer for allowing the latent heat energy to be transmitted to the hair by any one of wrapping the whole of the hair heating part to be concealed or wrapped only to the heating member of the metal body, a non-metallic slip layer superposed on the outside of the rubber layer to allow the hair to slip And a coating layer.

The non-metallic slip coating layer is different from silicon or urethane.

And a nonmetal slip coating layer is deposited on the outside of the circuit part to be waterproofed.

The non-metallic slip coating layer may be coated by any one of known spray coating methods for automatically spraying and drying the coating solution through nozzles, or known chemical vapor deposition methods for coating with vaporized vapor. .

The present invention can provide thermal energy to the hair even when the hair is wet or the medicine is applied to the hair, so that it is possible to perform the wet permanent operation and the hair and the hair heating part can be slipped smoothly. There is an effect of providing a hair iron which becomes possible.

In addition, since the present invention allows the latent heat energy to be imparted to the hair, the permer is completed before the moisture contained in the hair is evaporated at the time of the dry perming operation, and the moisture can be supplemented Therefore, it is possible to perform permanent surgery without damaging the hair.

Therefore, since the hair is not damaged at the time of permanent operation, it is possible to provide the effect of allowing the non-expert to perform the permanent operation by the hair iron very easily and satisfactorily.

In addition, since the hair can be slipped smoothly by the non-metallic slip coating layer in the state where the hair and the hair heating unit are in contact with each other, the hair is easily released or loosened when the permanent operation such as pulling the hair iron is performed, The operation can be performed very easily without difficulty.

In addition, the present invention has the effect of enabling quicker perming procedures because the medicine can be applied to the hair and thermal energy can be imparted directly by the hair iron.

And because of the rubber layer of the hair heating part, it is prevented in advance that the water or medical agent penetrates into the hair iron during the perming procedure, and the circuit part is also waterproofed so that electric shorting phenomenon and electric shock accident are prevented beforehand. It is the effect that makes it possible to do.

The present invention will be described in more detail with reference to the accompanying drawings.

1 to 3 illustrate an embodiment of the present invention, and show a hair ironer 10 for a wave permer having a hair heating unit 13.

The hair iron 10 has a handle 11 and a hair heating unit 15 having a metal heating member 15 heated by a heater 14 for applying heat energy to the hair H is provided in front of the handle 11, And a heating unit 13.

Further, a circuit unit 12 for controlling the heater 14 is incorporated in the handle 11. [ Reference numeral 121 denotes an electric cable.

Accordingly, the present invention is configured such that the rubber layer 16 is wrapped around the hair heating unit 13 so that the entire hair heating unit 13 is concealed.

 A non-metallic slip coating layer 17 is formed on the outer surface of the rubber layer 16 to allow the hair H to slip. The non-metallic slip coating layer 17 is coated with either silicon or urethane.

4 (a), the rubber layer 16 is formed on the outer surface of the metal heating member 5 so as to be superimposed on the outer surface of the rubber layer 16, The non-metallic slip coating layer 17 may be stacked.

As shown in FIG. 4 (b), the non-metal slip coating layer 17 may be formed on the outer surface of the metal heating member 15, (Cured) so as to be adhered with the adhesive agent 151 so that the adhesive agent 15 is sandwiched therebetween.

The non-metallic slip coating layer 17 'is coated on the outside of the circuit part 11 so as to be embedded in the inside of the grip part 11.

The non-metallic slip coating layer 17, 17 'may be coated by a spray coating method in which the coating solution is automatically sprayed through a nozzle and dried.

The other method is chemical vapor deposition (CVD) or physical vapor deposition (PVD). Since the deposition of the thin film by the CVD method has a smaller contribution of high-speed particles than that of the PVD method, There is an advantage of less damage to the surface.

CVD (Chemical Vapor Deposition) is a method in which gaseous compounds are reacted on the surface of a heated base material to deposit a high product on the surface of the base material. Chemical vapor deposition is a well known technique that is most widely used as a commercially available thin film manufacturing technique.

Accordingly, the nonmetal slip coating layer 17 or 17 'according to the present invention can be coated by any one of spray coating method and chemical vapor deposition method. The spray coating method or the chemical vapor deposition method Since the deposition method is a known coating technique known in the art, detailed drawings or descriptions will be omitted.

The hair iron 10 is provided with a glove 18 for pressing the hair H in a state where the hair H is wound around the hair heating unit 13. The glove 18 has a May be configured to be actuated to widen and pivot by pushbutton 181 as shown, or to act to widen and pivot by handle 181 'as shown in FIG.

Therefore, the glove 18 may be coated with the rubber layer 16 and the non-metallic slip coating layer 17 may be coated on the outer surface of the glove 18, but the glove 18 functions to press the hair H The rubber layer 16 and the nonmetal slip coating layer 17 do not necessarily have to be provided.

Therefore, in the hair iron 10 of the embodiment of the present invention, after the hair H is wound around the hair heating unit 13 at the time of perming operation, the heater 14 is activated, As shown in FIG. 5, the state of being transferred to the hair H through the non-metal slip coating layer 7 that is directly transferred to the heating member H after being transferred to the heating member 15 and transferred to the rubber layer 16 The hair H is given heat energy.

The metal heating member 15 has a relatively high heat transfer coefficient. As already known, a metal such as aluminum in which heat transfer is satisfactory is a metal having a heat transfer coefficient of 229 kcal / H and copper having a thermal conductivity of 386 kcal / relatively high. The metal heating member 15 has a heat transfer coefficient of 150 kcal / H < / RTI > or higher corresponds to a metal having a generally high thermal conductivity.

However, the thermal conductivity of the rubber layer 16, which is a non-metallic material, is relatively lower than that of the metal heating member 15 due to its material properties.

Therefore, the heat energy generated in the heater 14 is primarily transferred to the metal heating member 15 having a heat transfer coefficient of 150 kcal / H or more, and the thermal energy of the metal heating member 15 has a heat transfer coefficient of 0.20 kcal / H or less And is transferred to the hair H through the nonmetal slip coating layer 17 made of a non-metallic material.

Therefore, when the metal heating member 15 having a relatively high heat transfer coefficient receives heat energy from the heater 14, the heat is transferred to the outer surface of the metal heating member 15 rapidly due to the nature of the metal material, It can be quickly heated.

Since the rubber layer 16 of the metal heating member 15 has a weak strength due to its material properties, the metal heating member 15 serves as a pedestal for maintaining the shape of the rubber layer 16 as it is, It is preferable to adopt a metal made of aluminum or stainless steel.

Accordingly, when the rubber layer 16 having a low thermal conductivity is received from the metal heating member 15, the heat energy is not rapidly transferred from the inner surface to the outer surface of the rubber layer 16 without being rapidly transferred to the rubber layer 16. Accordingly, the rubber layer 16 and the nonmetal slip coating layer 17 The latent heat is transferred to the hair H, so that the hair H is given heat energy.

Therefore, when the non-metallic slip coating layer 11 is contacted with a liquid such as water or a permanent liquid on the hair H, latent heat energy is transferred to the non-metallic slip coating layer 11, so that the liquid does not evaporate instantaneously due to its physical properties.

When the latent heat energy is transferred to the liquid, the latent heat that is present on the outer surface of the non-metallic slip coating layer 17 and the rubber layer 16, which are in contact with the liquid, moves toward the liquid The temperature of the inner surface of the rubber layer 16 in contact with the inner surface of the rubber layer 16 becomes relatively low.

At this time, since the thermal conductivity of the rubber layer 16 is low, the thermal energy on the inner surface is not rapidly transmitted to the outer surface, so that the liquid (the treating agent) does not receive the heat energy of high temperature rapidly and only the latent heat energy The liquid is not rapidly heated instantaneously, so that the water contained in the treatment agent is not explosively evaporated.

Therefore, it is preferable that the rubber layer 16 of the present invention employs a rubber material having a relatively low heat transfer coefficient of 0.20 kcal / H or less. The non-metal slip coating layer 17 is in direct contact with a medicinal agent, It is preferable to coat it with silicone or urethane which has weatherability, aging resistance, oil resistance and abrasion resistance and has a smooth surface property in a cured state. However, in some cases, other types of base metal may be coated.

That is, the silicon or urethane constituting the non-metallic slip coating layer 17 has excellent heat resistance and can be continuously used because of its stable mechanical, electrical and chemical properties even at a high temperature. (15,000 Hrs) can be generally used between 150 ° C and 250 ° C, permitting permanent operation to be carried out at a permer temperature of typically about 100 ° C to 180 ° C.

In addition, since it has good cold resistance, it can be used at a cryogenic temperature of up to -115 ° C, and is harmless to the human body because it is nontoxic, colorless, odorless and physiologically inert.

And because of its good chemical resistance, it has excellent resistance to organic compounds such as permanent chemicals, which makes it possible to increase the lifetime of hair irons.

Further, since there is a hot water resistance which does not substantially change the physical properties even if it is precipitated in water for a long time or comes into contact with steam, no problem occurs even if the hair heating unit 13 is contacted with water or steam during the permanent procedure.

Since the insulator is waterproof and waterproof, the insulator can sufficiently function as an insulator even under harsh conditions. Therefore, moisture can not penetrate into the hair heating part 13, and the circuit part 12 is coated with the same components as the non-metal slip coating layer 17 As it becomes waterproof, electricity shortage caused by moisture or steam penetration can be prevented, and permanent operation can be planned safely without electric shock accident.

In particular, according to the present invention, since the non-metal slip coating layer 17 has latent heat together with the rubber layer 16, latent heat energy is given to the hair H, so that the water explosion phenomenon does not occur.

Since the non-metallic slip coating layer 17 has a smooth surface, the hair H can be easily released from the hair heating unit 15, So that the hair is not broken in the process of unwinding.

In addition, since the present invention can apply thermal medicine to the hair (H) and immediately impart heat energy to the hair by the hair iron, it is possible to perform the quicker permer treatment. In addition, in addition to imparting heat energy to the hair, So that it is possible to prevent hair from being damaged. In addition, since hair damage is not caused even by heat permer, non-expert can also perform permanent operation well.

FIG. 6 shows a configuration diagram of a hair H for explaining that it becomes a permanent operation to help understand the present invention.

6 (a), the hair H is composed of a cuticle Ha, a cortex Hb and a medulla Hc at the center.

The eye patch Ha is located at the outermost part of the hair H and overlaps like a scaly or tiled roof shape, but it is a material that appears translucent because there is no melanin pigment.

And the follicle (Hb) is located inside the skin (Ha) and occupies 85-90% by volume of most of the hair. The components of follicles (Hb) consist of caratin protein, intercellular interstitial material, cortical cells, and water, and cortical cells consist of cells in the form of fiber bundles. This is the part that is most affected by perming because it contains hydrophilic and melanin pigment.

In addition, the nature and texture of the hair vary depending on the amount of the insect material, which is considered to be the nutritional component of the hair. In other words, in addition to maintaining proper moisture and elasticity to the hair, it can be said that it is formed as a resilient wave permanent state, and it is very difficult to recover again if the insect material is lost due to chemical or physical causes.

The water quality (Hc) is located in the center of the hair (H) and can not be found on the fluffy or thin hair. It is mainly seen in the thick hair (H), and there are some melanin pigment particles.

Therefore, the principle of permer is to change the structure of hair (H) by the action of heat or chemical (pesticide) so as to artificially form wavy curl. Usually, in pre-treatment step, And the hair follicle Ha of the hair iron 10 is softened so that the follicle Ha is divided and opened as shown in Fig. 6 (b) Wave curl is formed so that the curled elastic yarn H is bent and then the curled elastic yarn Ha is restored to its original state as shown in Fig. 6 (a) by a neutralizing agent To become a permanent.

Therefore, the present invention is performed such that thermal energy is applied to the hair H by using the hair iron 10 in a state in which the skin Ha of the hair H is divided and opened as shown in FIG. 6 (c) As described above, even if a permanent medicine which receives the latent heat energy of the rubber layer 16 and the nonmetal slip coating layer 17 comes into contact with the nonmetal slip coating layer 17, it does not evaporate or burn down rapidly, Thermal energy can be transferred to the hair H in the state of FIG.

Therefore, even when the heat energy of high heat is transferred to the hair (H), the hair (H) is not only allowed to perform heat perming treatment in a wet state by the use of the warming agent but also the hair Moisture is not evaporated, and nutrients and water are replenished.

Accordingly, since the present invention is applied in a wet state even when high thermal energy is imparted to the hair H, the moisture in the fur material is not evaporated but replenished, so that the hair is dried and damaged more There is no problem at all.

In particular, even if the extreme damage caused by contact with the nonmetal slip coating layer 17 is caused by high temperature, the moisture contained in the constituent components of the fur material is not evaporated, so that the extreme damage is not stiffened or broken. It can be prevented in advance.

In the past, hair must be permanently applied by hair iron in the state of dry hair. "Hair cleaning → Hair drying → Permanent application → Permanent medicine washing → Hair drying → Thermal piercing by hair iron → Neutralizing agent → Neutralizer cleaning → Applying hair nutrient "I had to do a lot of perming procedures.

However, according to the present invention, the perming operation can be performed even in the state of wet hair, and thus, as a step of "applying a permanent agent → applying thermal perming by a hair iron of the present invention → applying a neutralizing agent → neutralizing agent cleaning → applying a hair nutrient" It is possible to greatly reduce the duration of the permanent operation.

The present invention enables dry permanent operation.

That is, according to the present invention, when performing permanent operation with the hair iron 10, the hair H is wound on the hair heating unit 13, and then heated for a while, and the hair H is loosened.

At this time, when the dried hair H is subjected to perming treatment, the present invention allows the latent heat energy to be imparted to the hair H, so that the hair H is rapidly heated without being transmitted high heat.

Therefore, the moisture contained in the hair H is not rapidly heated, and the hair H is gradually heated. Thus, in the initial stage after the hair H is wound on the hair heating unit 13, It is not evaporated.

In order to facilitate understanding of the present invention, since hair heat is rapidly transferred to the hair at a high temperature, the moisture contained in the hair is rapidly heated, thereby causing moisture evaporation, resulting in hair damage.

However, after the hair H is wound on the hair heating unit 13, the hair H is slowly heated by the latent heat energy during the heating for a while, and then the hair H is loosened until the temperature reaches the temperature at which the moisture is evaporated Even during permanent operation, even if the permanent hair is applied to the dried hair (H), the hair is not damaged.

Therefore, in the present invention, the moisture contained in the follicle constituents of the hair H is not evaporated during the dry permanent operation, and the hair H is further supplemented with water for the wet permanent operation, So that the non-expert can easily and easily perform the permanent operation.

In particular, since the surface of the non-metallic slip coating layer 17 is smooth, the hair H is easily released from the hair heating unit 15, so that the hair does not break during the hair releasing process, It is possible to perform permanent perming operation as well as wet permanent perming operation.

7 to 10 illustrate another embodiment of the present invention, in which a hair iron 10 'for a straight permer having one or more (two) hair heating portions 13 is shown.

The hair iron 10 'has a handle 11 and a metal heating member 15 which is heated by a heater 14 for applying thermal energy to the hair H is provided in front of the handle 11 And a hair heating unit 13, respectively.

In addition, a circuit portion 12 for controlling the heater 14 is incorporated in one of the knob portions 11. Reference numeral 121 denotes an electric cable, and reference numeral 111 denotes a resilient member for causing the pair of grip portions 11 to mutually oppose to each other in the outward direction.

Accordingly, the present invention is configured such that the rubber layer 16 is wrapped around the hair heating unit 13 so that the entire hair heating unit 13 is concealed.

 A non-metallic slip coating layer 17 is formed on the outer surface of the rubber layer 16 to allow the hair H to slip. The non-metallic slip coating layer 17 is coated with either silicon or urethane.

The rubber layer 16 is formed by forming a rubber layer 16 on the entire outer surface of each hair heating portion 13 using a molding die and then forming a nonmetal slip coating layer 17 on the outer surface of the rubber layer 16 After the rubber layer 16 is formed into the same shape as the hair heating section 13, the non-metal slip coating layer 17 is deposited on the outer surface of the rubber layer 16, (Cured) so as to be adhered with an adhesive agent so as to be fitted to each other.

The non-metallic slip coating layer 17 'is coated on the outside of the circuit part 11 so as to be embedded in the inside of the grip part 11.

The non-metallic slip coating layer 17, 17 'may be coated by a spray coating method that automatically spreads and dries the coating solution through a nozzle as described in one embodiment, or may be coated by a chemical vapor deposition .

10, the thermal energy of the heater 14 is applied to the metal heating member 15 and the heat generating member 15 as the hair H is put between the pair of the hair heating units 13 as shown in FIG. And is transferred to the hair H through the rubber layer 16 and the nonmetal slip coating layer 17.

Since the hair H receives the latent heat energy of the rubber layer 16 and the nonmetal slip coating layer 11, the hair H does not instantaneously rapidly heat the liquid such as water or perm solution due to its physical properties, As the moisture does not evaporate explosively, it is possible to perform a thermal perming treatment which imparts heat energy to the hair even in a wet state of hair or a state where the permanent agent is applied to the hair. The detailed description thereof will be omitted.

In addition, since the hair is wet even in the permanent procedure, it is the same as that of the embodiment described above that the hair H itself is in a state in which the moisture of the hair H itself is not evaporated but the nutrients and water are replenished. do.

On the other hand, the hair iron 10 'for straight perming is provided at one point of the hair H when the hair heating unit 13 is in direct contact with the hair H in a state where a medicine is applied on the surface of the hair H, The hair iron 10 'is moved from the upper portion of the hair H to the end portion of the hair H so as to be heat-transferred, so that the medicines do not burn or instantaneously evaporate Latent heat energy is transferred.

Particularly, when the hair iron 10 'is moved from the upper portion of the hair H to the end portion of the hair H to perform heat transfer, the surface of the non-metallic slip coating layer 17 is smooth, Since the hair H slides smoothly between the hair heating units 15, there is no hair scraping phenomenon and the hair is not broken, so that it is not difficult to perform the permanent operation very easily. As a result, It is also possible to perform the procedure.

11 and 12 show another embodiment of the present invention. In this case, only the metal heating member 15 having the heater 14 is covered with the rubber layer 16, and the outer surface of the rubber layer 16 And a non-metallic slip coating layer 17 is deposited on the non-metallic slip coating layer 17.

In this case, one or more (two) hair heating portions 13 are arranged in such a manner that the thermal energy of the heater 14 is applied to the metal heating member 15 The rubber layer 16 can impart latent heat energy to the hair through the nonmetal slip coating layer 17. [

Therefore, even in the above-described embodiment, latent heat energy of the rubber layer 16 and the nonmetal slip coating layer 17 is transferred to the hair H, so that even when the hair H is wet or the permanent medicine is applied, Since the hair is smoothly slipped at the time of permanent operation by the non-metallic slip coating layer 17, the operation of allowing the permanent hair to be applied to the dried hair H is the same as that of the previously described embodiments, Is omitted.

In addition, since the hair is wet even in the permanent procedure, it is the same as the previously described embodiments in that the hair H itself is not evaporated but is supplemented with nutrients or moisture.

Therefore, while the present invention has been shown and described with respect to a number of embodiments, the present invention is not limited thereto, and can be practiced in all hair irons that can perform permanent treatment by heater heat energy irrespective of the shape of hair irons.

Therefore, it should be understood that the present invention may be embodied in many other specific forms without departing from the spirit or scope of the general inventive concept as defined by the appended claims.
