The protrusion receiving grooves 242 are formed along the front and rear direction of the second heating element 200, and are symmetrically disposed on the left and right sides of the second central portion 220.

The first central portion 120 and the second central portion 220 may be brought into contact with each other in a state where the first heating element 100 and the second heating element 200 are closed, and particularly, hair may be spread. That is, when the hair is put between the first heating element 100 and the second heating element 200, the first heating element 100 and the second heating element 200 are closed to press the heating element 10 in the combing direction M. The hair is ironed and spread by the heat emitted from the first heating element 100 and the second heating element 200 while the hair moves between the first central portion 120 and the second central portion. The combing direction (M) is a direction opposite to the root direction of the hair, and can be understood as a direction in which combing is performed. In FIG. 1, the combing direction M is expressed as one specific direction, but the other direction may be set to the combing direction M according to the direction of the hair grip and the direction of the hair root.

In the present embodiment, the first central portion 120 and the second central portion 220 are formed in a flat plate shape, and as another example, the first central portion 120 and the second central portion 220 may be formed to include some curved surfaces.

The comb protrusion 140 and the storage groove 240 may be partially brought into contact with each other in a state where the first heating element 100 and the second heating element 200 are closed.

The first heating element 100 and the second heating element 200 are closed by pressing the upper and lower sides of the iron body 10 with the hair placed between the first heating element 100 and the second heating element 200, The hair passes between the first central portion 120 and the second central portion 220 and passes between the comb protrusion 140 and the storage groove portion 240, Various hair styling can be performed on the hair by the heat radiated from the first heating element 100 and the second heating element 200 and the curved shape of the comb protrusion 140 and the storage groove 240.

In addition, the comb teeth protrusion 142 disperses or homogenizes the portion of the hair directly pressed by the first and second heating elements 100 and 200 so that the user can easily perform hair styling even with a small force, the effect of reducing the damage of the hair is obtained at the same time.

The first heating element 100, the comb protrusion 140, the second heating element, and the storage groove 240 may be made of one material. As the material capable of transmitting heat, a high temperature may be generated in a short time, and material can be used as long as it is not deformed by the material, and can be made of a metal material preferably electrically insulated.

As shown in FIG. 4, the comb teeth protrusion 142 may be formed to have a slope 142b on both sides of the ridge 142a. The inclined surface 142b allows the hair to be uniformly dispersed along the inclined surface 142b and allows the heat provided by the first and second heating elements 100 and 200 to be dispersed or homogeneously distributed to the hair do.

The angle of inclination or the surface shape of the inclined surface 142b of the comb teeth protrusion 142 can be somewhat deformed in consideration of the machining aspect and the like.

The protrusion receiving grooves 242 are formed to have a groove shape corresponding to the shape of the comb teeth protrusion 142, for example, uniform heat can be provided to the hair by the projection receiving grooves 242.

The comb teeth protrusion 142 and the protrusion receiving grooves 242 may be formed in the respective comb teeth protrusions 142 in the closed state of the first heating element 100 and the second heating element 200 according to an embodiment of the present invention, “a” is formed between the inclined surface 142b of the protrusion 142 and the inner surface 242b of each protrusion receiving groove for receiving the comb tooth protrusion 142.

Asian women have an average hair thickness of 0.08 to 0.1 mm, and Western women have hair thicknesses of about 0.05 mm, compared to Asians. The size of the first gap (a) can be formed such that about 3 to about 7 strands can be passed side by side on the basis of, for example, the hair of an Oriental woman, and preferably the first gap (a) may be formed to be 0.32 mm to 0.52 mm.

The first heating element 100 and the second heating element 200 are closed and the hair moves through the comb teeth protrusion 142 and the protrusion receiving groove 242 as the hair iron 10 moves, A plurality of hairs are positioned in the first gap a formed between the inclined surface 142b of the protrusion receiving groove and the inner surface 242b of the protrusion receiving groove. The plurality of hairs may be heated by the first and second heat generating bodies 100 and 200 while the first heat emitting body 100 and the second heat emitting body 200 are closed without exerting excessive pressure on the hair from both sides, and a variety of hair styling can be performed while passing between the comb protrusion 140 and the storage groove 240 without a large resistance.

The first gap (a) minimizes the overpressure of the first and second heating elements (100, 200) directly on the hair, thereby preventing the cuticle of the hair from being broken due to high temperature and high pressure. It is possible to reduce the amount of water to be melted and removed.

The comb teeth protrusion 142 according to an embodiment of the present invention is formed to have an inclined portion 142c connecting the ridge 142a and the first center portion 120 along the left and right direction.

In the closed state of the first heating element 100 and the second heating element 200, the inclined portion 142c of each comb protrusion 142 and the protrusions 142 of the respective protrusions 142a second gap b is formed between the side surfaces 242c.

The second gap (b) temporarily dissolves the pressure and the high temperature directly applied to the hair passing between the first center portion 120 and the second center portion 220 while the second gap (b) is similar to the first gap a thereby minimizing the destruction of the cuticle. According to an embodiment of the present invention, the size of the second gap (b) may be about 3 to 7 strands so as to be parallel to each other when the oriental female hair is used as a reference, preferably 0.33 mm to 0.53 mm.

In FIGS. 5 and 6, the curved shape formed by the first and second central portions 120 and 220 and the inner side surface 242c of the projection receiving groove is formed by the comb tooth projection 142 and the projection storage groove. A variety of hair styling can be performed on the hair in addition to the curved shape formed by the hair 242.

The shape of the first and second center portions 120 and 220 and the curved shape formed by the first and second central portions and the inner side surface 242c of the projection receiving groove and the shape of the comb tooth projection 142 and the projection receiving groove 242. It is possible to give a straight or various kinds of curls to the hair by merely adjusting the rotation angle [alpha] of the ironing iron according to an embodiment of the present invention and combing in the combing direction M.

For example, the straightness of the hair may be determined in a state where the rotation angle [alpha] is 0 with respect to the plate-like surfaces of the first central portion 120 and the second central portion 220, can be accomplished by moving the hair iron in the combing direction (M).

As another example, a curl of hair may be formed in a state where the rotation angle [alpha] is not 0 based on the plate-like surfaces of the first central portion 120 and the second central portion 220, rotation can be accomplished by moving the hair iron in the combing direction (M).

The shape of the curl can be expressed differently according to the magnitude of the rotation angle [alpha], and the strong curl can be achieved as the rotation angle [alpha] is larger.

For example, C-curl at about 45°, J-curl at about 90°, and S-curl at about 180° may be formed at a rotation angle α of about 45°, The shape of the bending structure formed by the inner side surface 242c of the projection receiving groove and the shape of the comb tooth projection 142 and the projection receiving groove 242 can be changed.

Particularly, when the upper and lower portions of the iron plate are used upside down, for example, when the first heat generating element is positioned so as to be upward, even if the same rotation angle is given, a strong curl forming effect can be obtained.

The first heating element 100 according to the embodiment of the present invention is curved in the direction in which the left and right ends are away from the corresponding ends of the second heating element 200. FIGS. 5 and 6, the second heating element 200 is curved in a direction opposite to the position of the second heating element 200 that is, in a direction opposite to the position of the second heating element 200 and is formed to have a shape to surround a part thereof.

The second heating element 200 is formed to surround a part of the first heating element 100 and the first gap (a) and/or the second gap (b) are formed, when the two heat generating elements 100 and 200 evaporate, the entire amount is not discharged to the outside but a substantial amount can be present inside. Damage to the hair due to heat at a high temperature can be reduced due to moisture in the form of vapor present between the first heating element 100 and the second heating element 200.

The comb teeth protrusions 142 may be curved in such a manner that their outer ends (both ends of the left and right sides) are lowered when the ends of the first heating element 100 are curved, curling can be performed more easily by curving formation in which the outer end of the comb tooth protrusion 142 is lowered when the curl is formed.

The maximum projecting height (h) of the comb teeth protrusion 142 according to an embodiment of the present invention is preferably 2.4 mm to 2.6 mm.

When the maximum projecting height of the comb teeth protrusion 142 is larger than the above range, the hair is placed between the first heating element 100 and the second heating element 200 and the first heating element 100 and the second heating element 200 in the closed state, more force is required to move the ironing unit 10 in the lateral direction.

In addition, when the maximum projecting height of the comb teeth protrusion 142 is smaller than the above range, the curling effect on the hair may be lowered.

The center distance (p) between each of the comb teeth protrusions 142 according to an embodiment of the present invention is formed to be 3.5 mm to 4.5 mm.

When the center distance between the comb teeth protrusions 142 is too short, the tension is increased during the straight operation, so that more force is required to move the iron body 10 in the left and right direction, and the center distance between the comb teeth protrusions 142 is too long the effect of curling on the hair may be lowered.

The comb teeth protrusion 142 may be formed so that the cross-sectional area of the comb tooth protrusion decreases from the inner end portion to the outer end portion of the comb tooth protrusion 142. In this case, the hair positioned can be easily discharged from the hair iron 10 when the hair iron 10 is moved in the combing direction M.

The first heat generating body 100 and the second heat generating body 200 may have a first heat generating body coupling part 150 and a second heat generating body coupling part 250. The first and second heat generating body coupling parts 150, the first and second heating elements 100 and 200 can be firmly coupled to the hair iron 10 by being slidably coupled to a body coupling portion (not shown) formed on the hair iron 10.

The first heating element 100 and the second heating element 200 may be provided with electric heating parts (e.g., coils) on the outside of the first heating element 100 and the second heating element 200, respectively.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art without departing from the scope of the invention. Accordingly, the scope of the invention should be construed as being limited by the scope of the claims set forth as including many such variations.
