Description

Curling Iron {CURLING IRON}

The present invention relates to curling irons. More specifically, the present invention relates to a curling iron capable of applying heat and physical external force to the hair to produce a wave in the hair.

Curling Iron is a device that can apply heat and physical force to the hair to produce a wave to the hair. Curling iron is configured to open and fold in the form of tongs so that the user can physically hold the hair, the hot plate is provided in the portion in contact with the hair to generate a predetermined heat.

When the user pulls the hair while rotating the curling iron while holding the hair with the curling iron, the hair is twisted while being wound on the curling iron. At this time, as the binding between the particles constituting the hair is loosened by the heat of the hot plate, the hair is effectively bent. Since the heated hair is naturally cooled in the air, the binding between the hair particles is strengthened, thereby maintaining the wave state of the hair continuously.

Conventional curling irons are slowly cooled in the air of the hair, so binding between hair particles is likely to be delayed. Therefore, there is a problem that the wave of the curvature (curvature) desired by the user is released during natural cooling. As a result, in order to produce a wave of the hair desired by the user, it is inconvenient for the user to wind the hair above the desired curvature in consideration of the natural cooling time.

Meanwhile, FIG. 8 is a curling iron disclosed in registered patent No. 916545 (September 2, 2009; the following reference numerals refer to the registered reference No. 916545 and are not related to the reference numerals of the present invention).

It was configured to conduct heat. Therefore, the user's hair is not effectively cooled by the cooling plate 300, so that the binding between the hair particles is not strengthened, and it is difficult to continuously maintain the wave state of the hair. And because the outer circumferential surface of the curling iron is only semicircular, there was also a problem that the wave state of the hair is not sufficiently achieved.

And because there is a deep gap between the cooling plate (300, 400) and the connecting member (610, 910), and between the cooling plate (300, 400) and the first piece 100 and the second piece (200) In addition, the user's hair was pinched by this gap. In addition, the hot plate 110 is fixed to the first piece 100 and the second piece 200 is installed, the first piece 100 and the second piece 200 are coupled in the form of tongs by the hinge shaft 500. Since the entire surfaces of the two hot plates 110 do not contact each other accurately, there is also a problem in that the heating efficiency for the hair falls.

The present invention is to solve the conventional problems as described above, by increasing the contact area and the contact time of the cooling plate and the hair to easily form and maintain the wave state of the hair while increasing the cooling efficiency, the negative ion to the hair It is possible to supply, to solve the problem of hair pinching in the various grooves formed in the curling iron, and to provide a curling iron that can increase the heating efficiency by contacting the entire surface of the two hot plates.

The first piece 110 and the second piece 120 are rotatably connected to each other by the hinge shaft 130, so that the curling iron 100 can be opened and folded by the user's grip.

In addition, one side lower surface of the first piece 110 and one side upper surface of the second piece 120 are provided at positions where heat plates 140 generating heat face each other. As shown in FIG. 2, in the state in which the curling iron 100 is folded, the two hot plates 140 may be in close contact with each other. In addition, a control unit 150 having a switch or the like is formed on the side surface of the first piece 110 or the second piece 120 to control the heating of the hot plate 140. At this time, the hot plate 140 preferably comprises a nichrome wire containing nickel (Ni) and chromium (Cr).

In addition, on the opposite side on which the hot plate 140 is installed in the first piece 110 and the second piece 120, that is, the upper surface of one side of the first piece 110 and the lower surface of one side of the second piece 120 are respectively provided. The cooling plate 160 is provided. The two cooling plates 160 provided with the two pieces of the first piece 110 and the second piece 120 each have a curved surface, and two cooling plates 160 are provided on the outer surface of the first piece 110 and the second piece 120. Cooling plates 160 are spaced apart from each other by the boundary portion 162 at predetermined intervals in a symmetrical form. The cooling plate 160 is made of a material such as copper (Cu), aluminum (Al), brass (Cu + Zn) or iron (Fe) as a material having high thermal conductivity, and the hot plate 140 is in contact with the hair. It is a structure which can cool the hair heated by the.

4 is a side view of a curling iron according to the invention seen in the direction B of FIG. 1. Referring to FIG. 4, the hot plates 140 may be provided at positions where the first and second pieces 110 and 120 positioned vertically face each other. In addition, two cooling plates 160 are provided on the outer circumferential surfaces of the first piece 110 and the second piece 120, respectively, spaced apart by the boundary portion 162 so that the cross section of the curling iron 100 is circular. It is. In addition, a space 161 having a predetermined volume is formed between the cooling plate 160 and the first piece 110 and the second piece 120. The space 161 is formed to prevent conduction of heat generated from the hot plate 140 directly to the cooling plate 160. The space 161 may be formed by filling a material having a low thermal conductivity. have.

That is, in the curling iron 100 according to the present invention, the hair is heated between two hot plates 140 provided between the first piece 110 and the second piece 120, and the first piece 110 and the second piece. The hair is cooled while being in contact with the four cooling plates 160 provided on the outer surface of the piece 120. As a result, the binding between the particles constituting the hair is loosened by the heat of the hot plate 140, the hair 140 is bent while the wave state. Thereafter, the cooling plate 160 is rapidly cooled to connect the hair particles, thereby strengthening the binding of the hair particles, thereby continuously maintaining the wave state of the hair. At this time, since the cross section of the curling iron 100 is circular and the outer shape is a cylindrical structure by the four cooling plates 160, the user's hair is wound around the outer circumferential surface of the circle, so that the wave can be effectively formed on the hair. .

Meanwhile, the cooling plate 160 may be spaced apart from the direct contact with the hot plate 140 to prevent heat from being transferred from the hot plate 140. However, since the heat of the hair H is transferred to the cooling plate 160 when the hair H heated by the hot plate 140 is in contact with the cooling plate 160, the curling iron 100 is used. As the time increases, the cooling plate 160 may also be gradually heated, thereby reducing the cooling efficiency of the curling iron 100.

The present invention is provided with two cooling plates 160 spaced apart from each other in each piece (110, 120) in order to reduce the cooling efficiency reduction problem. That is, since the heat of the hair H heated by the hot plate 140 is first cooled in the first cooling plate 160 and then secondly cooled in the second cooling plate 160, the hair H is cooled. This is done in two steps. In addition, since the two cooling plates 160 are provided to be spaced apart from each other by the boundary part 162, even when the first cooling plate 160 is first heated by the heat of the hair H, the two cooling plates 160 are heated to the second cooling plate 160. It takes a long time to reduce the cooling efficiency. In addition, since two cooling plates 160 are provided, the area in contact with the time at which the hair H and the cooling plate 160 are in contact also increases, and therefore, the curling iron 100 according to the present invention has the hair (H) in comparison with the prior art. May provide an effect of increasing the cooling efficiency.

2. negative ion supply

Meanwhile, FIG. 5 is an enlarged view of the portion 'C' in FIG. 3. Referring to FIG. 5, the configuration of the anion generating unit 170 of the curling iron 100 according to the present invention is as follows.

Various devices for generating negative ions may be applied to the negative ion generating unit 170. For example, an ion generating device is installed to ionize particles in the air by using an electrode through which direct current flows, or tourmaline (Gourmet) or GNC is installed. As such, a substance which naturally generates negative ions may be installed.

And the negative ion generated in the negative ion generating means 170 is discharged toward the user's hair (H), the negative ion outlet in one side adjacent to the hot plate 140 on the side (110, 120) is installed (110, 120) 172 is inclined at a predetermined angle toward the portion where the hot plate 140 is located. In addition, a cover 174 is formed on the second piece 120 to manage the replacement of consumables included in the negative ion generating means 170 or the repair of the negative ion generating means 170. The cover 174 is opened and closed. As a result, it is preferable to facilitate the operation of installing and removing the anion generator 170 from the second piece 120.

3. Prevent hair from pinching

Next, Figure 6 is an exploded perspective view of the upper portion of the first piece 110 in the curling iron according to the present invention. Hereinafter, the cooling plate 160 in the curling iron 100 according to the present invention will be described with reference to FIG. 6 while being coupled to each piece 110 and 120, and looks at a structure for preventing the pinching of the hair H. For reference, although only the coupling structure of the first piece 110 and the cooling plate 160 is shown in FIG. 6, the coupling structure of the second piece 120 and the cooling plate 160 is also the same structure. Duplicate explanations are omitted.

Referring to FIG. 6, a boundary portion 162 is formed at the center of the first piece 110 in which the cooling plate 160 is installed, and a space 161 (see FIG. 4) is formed at the left and right sides of the boundary portion 162. do. In the first piece 110, a plate-shaped horizontal portion 116 is formed at a lower portion of the space 161 in a horizontal direction, and a plate-shaped vertical portion formed in a vertical direction at a portion contacting the boundary portion 162. 114 is provided. A portion formed between the horizontal portion 116 and the vertical portion 114 becomes the space 161, and the protrusions 112 face each other at both ends of the horizontal portion 116 and the vertical portion 114. It is formed to protrude in the direction.

In response to this, the surface of the cooling plate 160 is curved, and the lower portion of the cooling plate 160 is bent in the direction of the inner boundary portion 161 to form a flat bent portion 164. In addition, a groove 166 is formed between the two protrusions 168 by the two protrusions 168 protruding in the lower direction boundary portion 161 in the upper portion of the cooling plate 160.

As a result, in the process of combining the cooling plate 160 and the first piece 110, the bent portion 164 of the cooling plate 160 is in contact with the upper portion of the horizontal portion 116, the groove of the cooling plate 160 The vertical portion 114 is inserted into and fixed to 166. In addition, both end portions of the cooling plate 160 is fixed while contacting the contact portion 112 of the first piece (110). In order to fix the cooling plate 160 to the first piece 110, a separate coupling member (not shown) such as a bolt may be provided.

As such, the configuration of the bent portion 164, the protrusion 112, and the groove 166 is provided at the portion where the cooling plate 160 and the first piece 110 are coupled to each other, whereby the cooling plate 160 and the first piece 110 are provided. It is possible to prevent the phenomenon that the user's hair (H) is caught in the gap formed between the pieces (110).

In general, the deeper and narrower the gap formed between the cooling plate 160 and the first piece 110 is, the easier it is to pinch the hair (H). However, in the curling iron 100 according to the present invention, the end portion is bent inwardly while the end portion is flattened by the bent portion 164 between the bent portion 164 and the horizontal portion 116, the gap that can be pinched the hair (H) This will not exist. In addition, since the protrusions 112 contacting both end portions of the cooling plate 160 are formed in the first piece 110, the depth of the gap formed between the cooling plate 160 and the protrusion 112 becomes shallow and the user is in the gap. Will also reduce the chance of hair (H) pinched. In addition, since the vertical portion 114 of the first piece 110 is fixed to the groove 166 formed between the two protrusions 168 on the upper portion of the cooling plate 160, the cooling plate 160 and the vertical portion 114 are fixed. The problem that the hair (H) is caught between) is also solved.

4. Increased heating efficiency

Finally, Figure 7 is an exploded perspective view of the lower portion of the second piece 120 in the curling iron according to the present invention. Looking at the structure of the curling iron according to the present invention with reference to Figure 7 so that the entire area of the two hot plate 140 can easily contact each other as follows. In FIG. 7, only the structure of the second piece 120 is illustrated for convenience, but the structure of the first piece 110 is the same, and overlapping description thereof will be omitted.

Referring to FIG. 7, the hot plate 140 of the curling iron according to the present invention is installed with a predetermined elasticity with respect to the second piece 120 by the elastic member 142. Specifically, the hot plate 140 of the present invention is fixed to the second piece 120 as in the prior art, and does not move together with the second piece 120, but the elastic member 142 with respect to the second piece 120. It is installed to enable elastic movement within the elastic force range of). In addition, a cover 144 of an insulator material having a low thermal conductivity, such as heat-resistant plastic, is fixed to the lower portion of the hot plate 140, and the cover 144 is in contact with the elastic member 142, but the hot plate 140 is an elastic member. It is formed so as not to be in direct contact with the 142, to prevent the heat of the hot plate 140 is conducted to the second piece 120 to the cooling plate 160.

In the process of folding the first piece 110 and the second piece 120 by the user's grip in the curling iron 100 according to the present invention, the inside of the two hot plates 140 on the structure of the curling iron 100 of the tongs 140a) parts are first in contact with each other, and then, when the user further applies a grip force, a process of contacting the outer portions 140b of the two hot plates 140 is also in contact with each other.

The curling iron is not manufactured so that the two hot plates 140 or the two pieces 110 and 120 are horizontally precise from the beginning, or the two hot plates 140 are not kept horizontal as the hinge shaft 130 is loosened. May occur. In this case, in the curling iron as in the prior art, it is easy to cause a problem in that the entire surfaces of the two hot plates 140 cannot come into contact with each other. For example, a situation may arise in which only the outer surfaces 140b of the two hot plates 140 are in contact with each other. In this case, when the user's hair H, which is located between the two hot plates 140, is heated, heating efficiency for the hair H is heated. Also decreases.

However, in the curling iron 100 according to the present invention, the hot plate 140 is elastically coupled to the second piece 120 through the elastic member 142. Therefore, even if the two pieces 110 and 120 are not precisely made horizontally or the coupling of the hinge shaft 130 is loosened, each hot plate 140 may be formed by the elastic member 142. As the angle with respect to 120 is inclined, the two hot plates 140 are brought into contact with each other. As a result, the user's hair H, which is located between the two hot plates 140, may also be heated in a close contact between the two hot plates 140, thereby increasing the heating efficiency of the curling iron.

In addition, the elastic member 142 may include any configuration that can store a predetermined elastic force, such as a spring (see FIG. 7) or rubber or sponge, as shown in Figure 7 two springs are arranged at a predetermined interval Most preferably.

The present invention is not limited to the described embodiments, and various modifications and changes can be made to those skilled in the art without departing from the spirit and scope of the present invention. It belongs to the claims of the.
