The main body 100 can be formed up and down, and the main body 100 can be combined with the heating plate 210. At this time, the coupling with the heating plate 210 may be a fitting coupling based on the engaging shape of the main body 100 and the heating plate 210, and a bolting coupling may be used in parallel to supplement the fitting coupling.

In addition, the shape of both sides of the main body 100 may be a shape corresponding to the both sides of the heating plate 210, and preferably, both ends of the heating plate 210 and both ends of the main body 100 are It may have a shape that is continuously extended and connected. This is to facilitate wave forming of the hair. If both ends of the heating plate 210 and both ends of the main body 100 are formed to be stepped, a problem of the hair being bent as the step is formed occurs. It can be. Additionally, the main body portion 100 may be formed in a shape that reflects the curvature that corresponds to the shape of the curved surface (R100) of the heating plate 210 and maintains connectivity with the shape of the curved surface (R100).

The heating unit 200 may be combined with the main body 100, and the heating unit 200 may also be configured in an upper and lower direction according to the upper and lower configuration of the main body 100.

For example, the heating unit 200 is coupled to the main body unit 100 and is located in a heating plate 210 that contacts the hair to apply heat to the hair and an internal space of the heating plate 210, and generates heat through the heating plate 210 to apply heat to the hair. The heating plate 210 may be provided with a heating element 220 that conducts heat.

For example, the material of the heating plate 210 may be at least one selected from the group consisting of aluminum, stainless steel (SUS), and ceramic materials, and preferably may be aluminum. This is because aluminum has good thermal conductivity, and because of this, the heating element 220 can be used with a small heating capacity or a small size, which can be more economical. However, it is not limited to this, and the material of the heating plate 210 can be modified in various ways at a level that is obvious to those skilled in the art.

In addition, the heating plate 210 may be located above and below the main body 100, so that two heating plates face each other. In this case, the heating plate 210 has curved surfaces R100 in the longitudinal direction on both sides. It is formed so that both ends of the heating plate 210 facing each other can be spaced apart by a predetermined distance.

This is a means to solve the problems of the conventional straightening iron. In the hair iron of the present invention, the heating plate 210 has curved surfaces (R100) formed in the longitudinal direction on both sides, and both ends of the heating plate 210 face each other. By being spaced apart by a predetermined distance, the hair can be naturally curled according to the space formed between the curved surfaces (R100) and the curvature of the curved surface (R100). In addition, hair can be naturally wrapped along the shapes of both sides of the main body 100, which are formed to correspond to the curved surface R100 formed on the heating plate 210, making it easy to wavy hair styling.

In addition, the curvature of the curved surface (R100) is the ratio of the thickness and width of the heating plate 210 and the ratio of the curved surface (R100) and the flat surface (P100) based on the width direction of the heating plate 210 (D110+D120:D200) ) can be adjusted depending on the

For example, the ratio of the thickness of the heating plate 210 to the width of the heating plate 210 may be 1:7 to 1:10. At this time, the ratio (D110+D120:D200) of the curved surface (R100) and the flat surface (P100) based on the width direction of the heating plate 210 may be 1:3 to 3:1.

For example, the heating plate 210 shown in FIGS. 4 and 5 shows a case where the thickness and width ratio is 1:10. In this case, FIG. 4 shows the ratio (D110) of the curved surface (R100) and the flat surface (P100). +D120:D200) is 1:3, FIG. 5(a) shows the case where the ratio (D110+D120:D200) of the curved surface (R100) and the flat surface (P100) is 1:1, and FIG. 5(b) shows the case. is a diagram showing a case where the ratio (D110+D120:D200) of the curved surface (R100) and the flat surface (P100) is 3:1.

In addition, in the hair iron of the present invention, the thickness and width ratio of the heating plate 210 is 1:10, and the ratio (D110 + D120:D200) between the curved surface (R100) and the flat surface (P100) of the heating plate 210 is 1. :1 is most preferable, but is not limited to this.

In addition, the hair iron according to the first embodiment of the present invention may further include a heat blocking unit 300 that blocks heat from the heating unit 200 from being transferred to the main body 100.

For example, the heat blocking unit 300 may be located in the internal space of the main body 100 and attached along the shape of the main body 100. This means that when the main body part 100 touches the scalp or skin during hair styling, heat from the heating part 200 is transmitted to the main body part 100 by the heat blocking part 300. This makes hair styling easier.

At this time, the material of the heat blocking unit 300 may be glass fiber or ceramic, but is not limited to this and can be variously modified into materials with excellent fire resistance and heat insulation properties.

For example, the material of the heating plate 210 may be at least one selected from the group consisting of aluminum, stainless steel (SUS), and ceramic materials, and preferably may be aluminum. This is because aluminum has good thermal conductivity, and because of this, the heating element 220 can be used with a small heating capacity or a small size, which can be more economical.

Additionally, the material of the heating plate 210 may be different from that of the first heating plate 211 and the second heating plate 212. For example, the first heating plate 211 may be made of aluminum, and the second heating plate 212 may be made of ceramic. This is to make the hair resistant to damage and easy to style the hair by varying the temperature of the first heating plate 211 and the second heating plate 212. However, it is not limited to this, and the material of the heating plate 210 can be modified in various ways at a level that is obvious to those skilled in the art.

Additionally, the temperature of heat applied to the hair may be set differently by varying the thickness of the first heating plate 211 and the second heating plate 212.

Subsequently, the first heating plate 211 may be positioned above and below the main body 100, so that the two heating plates face each other. In this case, the first heating plate 211 extends in the longitudinal direction on both sides. A curved surface R100 is formed so that both ends of the first heating plate 211 facing each other can be spaced apart by a predetermined distance.

The hair iron of the present invention has curved surfaces (R100) formed in the longitudinal direction on both sides of the first heating plate 211, and the first heating plate 211 faces each other. ), the two ends of the hair can be naturally curled according to the space formed between the curved surfaces (R100) and the curvature of the curved surface (R100) by being spaced apart by a predetermined distance. In addition, hair can be naturally wrapped along the shapes of both sides of the main body 100, which are formed to correspond to the curved surface R100 formed on the heating plate 210, making it easy to wavy hair styling.

In addition, the curvature of the curved surface (R100) is the ratio of the thickness and width of the first heating plate 211 and the ratio (D110) between the curved surface (R100) and the flat surface (P100) based on the width direction of the first heating plate 211. +D120:D200).

For example, the ratio of the thickness of the first heating plate 211 and the width of the first heating plate 211 may be 1:7 to 1:10. At this time, the ratio (D110+D120:D200) of the curved surface (R100) and the flat surface (P100) based on the width direction of the first heating plate 211 may be 1:3 to 3:1.

Additionally, the second heating plate 212 may be formed in the height direction on both sides of the first heating plate 211. At this time, the second heating plate 212 may have a shape corresponding to both sides of the first heating plate 211, and preferably, both ends of the first heating plate 211 and the second heating plate 212 are continuous. It may have a shape that is extended and connected. This is to facilitate wave forming of the hair, and if both ends of the first heating plate 211 and the second heating plate 212 are formed to be stepped, a problem of the hair being bent as the step is formed occurs. It can be. Additionally, the second heating plate 212 may be formed in a shape that corresponds to the shape of the curved surface R100 of the first heating plate 211 and reflects the curvature that can maintain connectivity with the shape of the curved surface R100.

In addition, the heating element 220 may include a first heating element 221 located in the inner space of the first heating plate 211 and a second heating element 222 located in the inner space of the second heating plate 212. You can.

For example, the hair iron according to the second embodiment of the present invention can adjust the heating temperatures of the first heating element 221 and the second heating element 222 to be different from each other through a control unit (not shown), which causes , can enable more diverse types of hair styling.

In addition, the hair iron according to the second embodiment of the present invention may further include a heat blocking unit 300 that blocks heat from the heating unit 200 from being transferred to the main body 100.

This makes hair styling easier.

At this time, the material of the heat blocking unit 300 may be glass fiber or ceramic, but is not limited to this and can be variously modified into materials with excellent fire resistance and heat insulation properties.

Since the configurations of the hair iron according to the third embodiment of the present invention described below can be applied in the same way as those described in the first and second embodiments of the present invention, detailed description within the overlapping scope will be omitted. do.

Figure 7 is a cross-sectional view of a hair iron according to a third embodiment of the present invention. In addition, Figure 7 is a diagram showing only the lower part of the hair iron configured to face each other up and down, and the upper part is omitted because it is symmetrical to the lower part.

Referring to FIG. 7, the hair iron according to the third embodiment of the present invention includes a main body 100 spaced apart at a predetermined angle about the hinge axis; A heating unit 200 including a heating plate 210 connected to the main body 100 and a heating element 220 located in an internal space of the heating plate 210; and a heat blocking unit 300 that blocks heat from the heating unit 200 from being transferred to the main body 100.

The heating plate 210 may include a first heating plate 211 and a second heating plate (not shown) formed in the height direction on both sides of the first heating plate 211.

In addition, the curvature of the curved surface R100 formed in both longitudinal directions of the heating plate 210 may be changed as it moves up and down.

Specifically, the first heating plate 211 includes a 1-1 heating plate (211-a) and a 1-2 heating plate (211-b), and the 1-2 heating plate (211-b) is the first heating plate (211-b). 1-1 When the heating plate (211-a) rises, it changes from the first shape (M100, see Figure 7(a)) to the second shape (M200, see Figure 7(b)) around the rotation axis (C100). can be rotated

In addition, the rotation axis (C100) of the 1-2 heating plate (211-b) is made of an elastic body such as a spring, so that when the 1-1 heating plate (211-a) descends, the rotational restoring force of the rotation axis (C100) It can be rotated from the second shape (M200) to the first shape (M100).

At this time, the hair iron according to the third embodiment of the present invention may further include a dial unit 400 that moves the first heating plate 211 up and down through a dial-type rotation operation.

For example, the first heating plate 211 is connected to the heat blocking unit 300, and a protruding portion (F100, see FIG. 7(b)) is formed at the bottom of the heat blocking unit 300, The protruding portion F100 may be introduced into the dial portion 400.

When (211-b) is the second shape (M200), the length (D200) of the plane (P100) may be shorter. This is because when the dial unit 400 is rotated clockwise, the 1-1 heating plate 211-a rises, and the curved portion of the 1-1 heating plate 211-a is drawn out. am.

As a result, it is possible to easily adjust the curvature of the curved surface (R100) and the length (D200) of the plane (P100) by moving the heating plate (210) up and down through the rotation of the dial unit (400), thereby making it possible to easily adjust the curvature of the curved surface (R100) and the length (D200) of the plane (P100). Styling can become easier.
