Description

Hair iron {Hair iron}

The present invention relates to a hair iron, and more specifically, to a hair in straight hair by straight hair or straight perm, curling can be easily and stably formed, as well as a hair iron that can be easily performed in various forms of wave setting. It is about.

In general, the hair iron is used to form various types of waves on the hair by using heat generated from the heater, or, on the contrary, to straighten the hair of the curly or wave state by straightening the hair. It is a kind of beauty equipment widely used for the purpose of maintaining it for a long time by transforming it into a desired shape.

In particular, long hair women can not only manage their hair relatively easily without the help of a professional hairdresser to achieve a good hairstyle, but also hair in a relatively short time, unlike a perm that requires long-term treatment with chemicals. You can easily change the style and produce the style you want, and the curls are more natural than the wave of the perm that uses rods, so you can create an elegant hair design.

These hair irons are provided in various forms, and the most common types of hair irons are shown in FIGS. 1 and 2.

It is connected to a power cord 1 at one end thereof, and a pair of tongues (tong: 2, 3) having a temperature control device (not shown) therein allows a hinge shaft ( It is connected by a hinge (4), and it takes the form of a tong that can be rotated within an angle range. In addition, inside the distal end portions of the upper tongue 2 and the lower tongue 3, the upper heat plate 6 and the lower heat plate 7 on the plate on which the heater 5 is mounted are provided to face each other.

However, in the conventional hair iron having such a configuration, since the upper and lower hot plates 6 and 7 are formed in a flat surface, in order for the operator to form curls on the hair, as shown in FIG. The curl is formed using one edge of the lower heating plate 7 by twisting the wrist and pulling while rotating the iron while holding a certain amount of hair H between the heating plates 7.

Accordingly, it tends to pull excessively by twisting the wrist excessively for good curling while rotating the iron, thereby causing the hair (H) and the scalp to be damaged, while the desired shape of the curl due to the structural characteristics of the hot plate (6) (7). There was a difficult problem getting it.

That is, in the conventional iron, since the hot plate 6 and 7 have a simple planar shape, the hair H is strongly gripped when the iron is rotated for curling, and the gripped portion is preferentially heated to a straight shape. Even when twisting the iron while rotating to pull the curl (H) by the subsequent edge is difficult to form.

Because of this, repeated treatments are frequently performed several times to obtain desired curls. In this case, excessive heat can cause severe hair damage, as well as excessive fatigue on the operator's wrists and shoulders, and if the disease persists for a long time. There is also concern.

Furthermore, in the hair H held between the upper and lower hot plates 6 and 7, the moisture contained in the process evaporates to generate water vapor. In the conventional iron, the steam of the iron is not dried. Since the curl is formed to the edge of the hot plate 6 through rotation, it is difficult to form a good curl and the curl is easily released after the molding.

On the other hand, to solve the problem of such a flat iron plate, as shown in Figure 4, the iron is composed of a circular heating element (8) and an arc-shaped glove (9) surrounding it, gripping the hair between both Curling irons are also provided for curling while rotating.

However, the width of the hot plate of the curling dedicated iron has a width smaller than the width of the hair iron of the general flat hot plate method, which is configured to hold and curl a small amount of hair for easy shaping of the wave.

Therefore, the procedure is slowed down as much as the procedure is performed with less amount of hair, and the hair is severely damaged by applying heat to the hair for a long time over several times.

In addition, there is still a problem that curls are easily loosened by the spring back phenomenon of the hair after the procedure because there is no drying process of the steam generated in the hair as in the flat hot plate iron described above.

Recently, in addition to wave perm and straight perm, modified hairstyles using the above-described iron mechanisms such as volume perm and volume straight wave perm have become popular. This refers to a procedure that saves hair roots. This is called a "volume up" operation.

This volume up will make the hair look more rich and elegant. To do this, the wave or straightness of the entire hair must be good, but more importantly, the root of the hair must be alive from the scalp. .

However, due to the difference in the experience of the operator or the plastic surgery ability, the conventional general iron device has a very difficult time to deform the hair design in addition to the standardized procedure.

In other words, for the volume up procedure, the root of the hair should be kept as close as possible to the scalp while holding the hair with the iron. Due to its structural characteristics, the flat hot plate iron of 'Hot' requires a lot of attention and skill, but it is difficult to realize a good volume, and there are also concerns about scalp.

Therefore, for the volume up procedure, the curling-only iron and the like were mixed together to save the roots before the procedure.

The present invention was devised to solve such a conventional problem, and provides a hair iron that can easily and safely form curls on straight hair or straight perm hair as well as maintain molded curls for a long time. The purpose is.

Another object of the present invention is to provide a hair iron that can more easily perform the hair volume up operation, which can effectively restore the root portion of the hair effectively, and can also set various types of wave to the hair.

Still another object of the present invention is to provide a hair iron which can reduce the hair treatment time by allowing the discharge of moisture generated by applying heat to the hair during hair treatment, easily and quickly.

Another object of the present invention is to provide a hair iron which is designed to minimize the damage of the hair by reducing the direct contact area between the hair and the hot plate.

The first embodiment of the hair iron according to the present invention for achieving the above object, a pair of upper and lower tongues that can be opened and closed at a predetermined angle around the hinge axis, and is provided to face the inner side of the upper and lower tongues In the hair iron comprising a pair of upper and lower hot plates for heat-molding in a state held between the two,

The lower heating plate is provided with a heating portion for holding and heating the hair, and a curling protrusion for protruding from at least one side of the heating portion to form a space between the heating portions and forming curls on the hair while subsequently moving to the heating portion. Characterized in that.

In the present invention, it is possible to form strong curls by curling protrusions while the hair heated in the heating part passes through the space and is discharged and dried to a certain extent, according to one preferred embodiment of the present invention. The curling protrusion protrudes outward from the case side of the lower tongue so that the curling protrusion is firmly grounded to the hair without curling the case when curling while rotating the iron to ensure stable curling operation.

In addition, according to another preferred feature of the first embodiment of the present invention, a plurality of curling protrusions are provided at intervals, so that a continuous curling effect can be obtained in one operation, and more reliable curling is possible.

In addition, a second embodiment of the hair iron according to the present invention for achieving the above objects, a pair of upper and lower tongues that can be opened and closed at a predetermined angle around the hinge axis, and provided to face the inner side of the upper and lower tongues A hair iron comprising a pair of upper and lower hot plates which are heat-molded in a state in which the hair is held between them, wherein the lower hot plate is provided with grooves in a longitudinal direction near at least one edge in the width direction of the lower hot plate. And a heating section for holding and heating the curling projections for curling the hair while moving subsequent to the heating section.

This second embodiment also allows the hair heated in the heating portion to form strong curls by the subsequent curling protrusion in a state in which water vapor is discharged and dried while being dried to a certain degree, which is a desirable feature of the second embodiment. According to the present invention, grooves are formed to be spaced apart in the width direction of the lower hot plate, and a plurality of curling protrusions are provided, so that a continuous curling effect can be obtained in one operation.

On the other hand, in the first and second embodiments of the present invention, the heating portion of the lower heating plate may be composed of a flat surface, it may be composed of a curved surface that is upwardly convex. Of course, in this case, the contact surface of the upper hot plate is configured in a form corresponding to the lower hot plate.

In particular, in the case where the heating portion of the lower hot plate is curved, the tip of the curling protrusion is positioned on the same curvature line as the heating portion, thereby making it possible to more reliably smooth and natural curling.

In addition, a third embodiment of the hair iron according to the present invention for achieving the above object is provided with a pair of upper and lower tongues that can be opened and closed at a predetermined angle about the hinge axis and opposed to the inner side of the upper and lower tongues. In the hair iron comprising a pair of upper and lower hot plates which are heated and molded in a state where the hair is held between them,

The surface of the lower heating plate is formed as a curved surface of the predetermined curvature upwardly convex, a plurality of grooves are formed on the surface of the lower heating plate spaced apart in the width direction so that the surface of the lower heating plate is composed of a plurality of protrusions, the upper surface facing the lower heating plate The contact surface of the hot plate is characterized in that the curved surface of the curvature corresponding to the curved surface of the lower hot plate.

In the third embodiment, a plurality of protrusions and recesses arranged in succession may be used to continuously process heating, air cooling, steam discharge, and curling in multiple stages, thereby forming curls very simply and reliably.

According to a preferred feature of this third embodiment, each of the protrusions has a curved surface with a predetermined curvature and is strongly grounded to the hair, thereby increasing the efficiency of curling.

According to the present invention, the curling protrusion is spaced apart from the heating portion holding the hair and the space (groove), the pressure is strongly pressed to the local sliding contact while moving subsequent to the heating portion during the procedure by the rotational movement of the iron. It will be able to easily form a strong curl edge.

In particular, the water vapor generated in the preceding heating unit is easily discharged through the space (groove), as well as quickly dried by air and radiant heat flowing through the space (groove), so that the curling protrusion is heated and dried to some extent. Since the hair is pressed in a state, it is possible to mold the curl more strongly and reliably, and it is possible to keep it stable for a long time without being easily released after the molding.

Therefore, curls can be reliably formed without repeating the procedure several times as in the prior art. Accordingly, the procedure is very easy and the fatigue of the operator can be significantly reduced. It is possible to achieve more simple and reliable curling.

In addition, since the curling protrusion has a curved surface spaced apart from the heating part, the volume of the root of the hair can be effectively saved without excessive use of the wrist or the arm, so that the volume up operation can be performed more easily.

Moreover, the direct contact between the hair and the hot plate can be reduced, thereby providing an effect of minimizing hair damage by the hot plate.

In addition, when the heating part of the lower heating plate has a convex curved shape, the hair in the straight state can be easily formed freely during the setting of the iron or the iron perm operation, and various types of wave setting operations are possible.

Such specific features and other advantages of the present invention will become more apparent from the following description of the preferred embodiments with reference to the accompanying drawings.

5 to 8b, the hair iron according to the first embodiment of the present invention, like the conventional hair iron, basically a rod-like upper tongue 10 for holding and heating the hair (H) therebetween and It consists of a lower tongue 20, one end of which is rotatably coupled by the hinge shaft 30 has a configuration of a tongs that can be rotated within a certain angle range.

And, one end of the upper tongue 10 and the lower tongue 20 is connected to the power cord 40, the inside of the lower tongue 20, the temperature control device 50 is connected to the power cord 40 circuitry It is built in.

Inside the front end portions of the upper tongue 10 and the lower tongue 20, an upper hot plate 12 and a lower hot plate 22 on which heaters 13 and 23 are mounted, respectively, are provided through the housings 14 and 24. Is provided so as to be mounted in the head 21 and is heated by the respective heaters 13 and 23 so that the hair H held therebetween can be molded.

Hair iron of the present invention having such a basic configuration is configured to be convenient for the lower hot plate 22 to curl the hair (H) of the straight hair according to the features of the first embodiment of the present invention.

As a configuration for this, the lower heating plate 22 protrudes by a predetermined length outwardly (horizontal direction) from the lower end portions of both sides of the heating portion 22a in contact with the upper heating plate 12 and both side lower ends of the heating portion 22a. And a curling protrusion 22b which slides while locally pressing the hair H after the heating portion 22a.

Accordingly, a constant space 22c is formed between the heating part 22a and the curling protrusion 22b, and this space 22c functions as an air passage during the curling procedure to vaporize water vapor generated when the hair H is heated. It is easy to discharge quickly and at the same time promote the drying of the hair (H) by indirect radiant heat.

Preferably, the tip of the curling protrusion 22b is formed in a curved shape so as to gently contact the hair H to prevent damage to the hair H and to form natural curl.

In other words, if the curling protrusion 22b is sharply configured to compress the hair H locally for strong curl formation, not only can the hair H be damaged by excessive local pressure but also the iron is rotated. While the pulling operation is not smooth, especially after the procedure, there is a high possibility that the shape of the curl may not be natural, and the tip of the curling protrusion 22b is configured to have a curved shape with an appropriate curvature.

In addition, the curling protrusion 22b is preferably protruded outward by a predetermined length s from the outer surface of the lower tongue 20 case 21 so as not to interfere with the case 21 of the lower tongue 20 during the procedure. Do.

8A and 8B, when the curling operation is performed while rotating the iron holding the hair H, the tip of the curling protrusion 22b is the outer surface of the lower tongue 20 case 21. The case of the lower tongue 20 because the case 21 is in contact with the hair (H) because the curling protrusion (22b) can not reliably press the hair (H) when located on the line or inside the line such as (21) to protrude more than the outer surface to strongly press the hair (H) without interference during the curling procedure.

Meanwhile, the upper hot plate 12 is formed in a planar shape corresponding to the heating part 22a of the lower hot plate 22, and both edges thereof have a round shape, so that the upper and lower tongues 10 and 20 have hair (H). When gripping the), the hair (H) is configured to be stably and easily grasped without breaking.

The upper hot plate 12 may be configured to have a width corresponding to the width of the lower hot plate 22, but preferably, the upper hot plate 12 has a width larger than the width of the lower hot plate 22 so that the space 22c of the lower hot plate 22 is formed. It is formed to cover.

Accordingly, by indirectly radiating heat up and down together with the space 22c of the lower heating plate 22 to the hair H that has passed through the heating part 22a during the curling procedure, the drying of the hair H is further promoted. This makes curling by the curling protrusion 22b easier.

This first embodiment of the hair iron of the present invention, as shown in Figure 8a is a hair iron as shown in Figure 8b in a state in which a certain amount of hair (H) is held between the upper and lower hot plates (12, 22) The curl is formed by the curling protrusion 22b by pulling while rotating appropriately.

At this time, the water vapor generated in the hair H is not only quickly discharged through the space 22c subsequent to the heating portion 22b, but also to the radiant heat provided at the edge of the space 22c and the upper heating plate 12. The rapid drying of the heated hair (H) is achieved.

Accordingly, the subsequent curling protrusion 22b applies a local strong sliding pressure to the hair H in the heat-dried state, thereby making it possible to reliably form curls even in a single procedure, and also form curls after the procedure. It is not easily released and can be kept stable for a long time.

In addition, since the curling protrusion 22b protrudes horizontally from the side of the lower heating plate 22, the curling protrusion 22b can be easily performed without excessively approaching the iron close to the scalp during the volume up procedure.

In addition, since the heating part 22a of the upper hot plate 12 and the lower hot plate 22 is formed in a flat surface, not only the curling procedure but also a procedure of straightening the curly hair or wave hair H in a straight state is also possible. .

The remaining reference numerals 15 and 25 are known frames which are integrally provided for installing the upper and lower hot plates 12 and 22 on the respective housings 14 and 24, and 16 and 26 are used when holding the hair H. It is an elastic member for imparting appropriate tension to the cases 11 and 21.

9 shows another form of the first embodiment of the hair iron according to the present invention. This is in the configuration of the first embodiment described above, in which the heating portion 22a of the lower hot plate 22 is formed in a curved shape with a predetermined curvature upwardly convex, and the upper hot plate in contact with the heating portion 22a of the lower hot plate 22. The contact surface 12a of (12) is the structure formed in the concave curved surface of the same curvature corresponding to the heating part 22a.

In this configuration, curling is more advantageous because the heating part 22a is curved, in addition to having the same effect as that of the heating part 22a, and the formation of the wave formed by alternatingly repeating curling is particularly advantageous. It has an easy advantage.

Therefore, it is preferable for the curling protrusion 22b to form smooth curl whose tip is located on the same radius of curvature as the curvature of the heating portion 22a.

10 and 11 schematically show still other forms of the first embodiment of the hair iron according to the present invention, in which the heating portion 22b of the lower heating plate 22 described above is a planar and curved surface. A second curling protrusion 22d is further provided between the 22a and the curling protrusion 22b to form a plurality of curling protrusions 22b and 22d and a plurality of spaces 22c and 22e, respectively.

The hair iron of the present invention having such a configuration allows the drying through the spaces 22c and 22e and the local sliding compression by the curling protrusions 22b and 22d after the heating of the hair H during the curling procedure. As a result, curling of the hair H becomes easier and more reliable.

Meanwhile, FIG. 12 shows a second embodiment of the hair iron according to the present invention, except for the lower heat plate 62 mounted on the case of the lower tongue, the remaining parts are the same as those of the first embodiment described above. Only couples are drawn and shown, and corresponding descriptions will be avoided by avoiding duplicate explanations.

In the second embodiment, concave grooves 62c are formed near both edges of the lower heating plate 62, respectively, to form a planar heating portion 62a for holding and heating the hair H, and the heating portion 62a. Curling protrusions (62b) to form a curl by locally pressing the hair (H) between the grooves (62c) between both sides are provided with spaced apart.

The recess 62c functions as an air passage like the space 22c of the first embodiment described above, and when steam moves while rotating the iron during the curling procedure, water vapor generated from the heated hair H while passing through the heating portion 62a. It quickly dissipates and provides indirect radiant heat to promote drying of hair (H).

Subsequently, the curling protrusion 62b subsequent to the hair H, which has been somewhat dried, is locally strongly squeezed and pressed to make it possible to easily and reliably form strong curled edges as in the first embodiment. The procedure can also be performed more easily.

Therefore, the tip of the curling protrusion 62b may be formed to have a curved surface as shown in order to prevent the damage of the hair H while being able to press the hair H strongly, and to form natural curl by a smooth curling operation. Do.

Also in this second embodiment, the upper hot plate 12 may be formed to have a width corresponding to only the heating portion 62a of the lower hot plate 62, but preferably has a width larger than the width of the lower hot plate 62b. It is configured to cover 62c to promote rapid drying of the hair H.

FIG. 13 shows another form of the second embodiment of the hair iron according to the present invention, which is a curved surface having a predetermined curvature in which the heating portion 62a of the lower heating plate 62 is convex upward in the configuration of the second embodiment. The contact surface 12a of the upper hot plate 12 in contact with the lower hot plate 62 is formed of a concave curved surface of curvature corresponding to the curved surface of the lower hot plate 62.

At this time, the front end of the curling projection (62b) is preferably located on the radius of curvature of the heating portion 62b, the upper hot plate 12 is larger than the width of the lower hot plate 62 to cover the groove (62c) It is formed in a large width.

As a result, curling of the hair H is more advantageous and smoother curling can be obtained than in the case where the heating part 62a is planar, and easy wave molding is possible.

Figure 14 shows another form of the second embodiment of the hair iron according to the present invention, which in the second configuration of the second embodiment, a plurality of grooves (62c) (62e) are continuously spaced apart to form a curling protrusion It is the structure provided with two or more (62b) and 62d.

Also in this case, it is, of course, preferred that the curling protrusions 62b and 62d are equally positioned on the radius of curvature of the heating portion 62a.

In this configuration, the iron has the same effect as the above-described embodiments, and in addition, a procedure of locally compressing the hair H passing through the heating part 62a and then pressing it locally is performed continuously in one operation. As a result, curls can be formed very reliably and stably, and a stable curl state can be maintained for a long time after the procedure.

Meanwhile, FIG. 15 shows a third embodiment of the hair iron according to the present invention, and this embodiment also differs from the above-described first and second embodiments only in the configuration of the lower heating plate 72 embedded in the case of the lower tongue. For the sake of convenience, only the necessary parts are drawn and the corresponding codes are described to avoid duplicate explanation.

In the third embodiment, the surface of the lower hot plate 72 for holding and heating the hair H together with the upper hot plate 12 is formed of a curved surface having a predetermined curvature upwardly, and a plurality of grooves ( 72b) is formed to be spaced apart from the plurality of protrusions (72a) is provided on the surface.

Therefore, the contact surface 12a of the upper hot plate 12 is formed as a concave curved surface of curvature corresponding to the curvature of the lower hot plate 72 to uniformly contact the tip of each of the projections (72a).

At this time, each of the projections (72a) is preferably located on the same radius of curvature so as to form a uniform shape of curls without undulation in the hair (H), each projection (72a) due to the characteristics of the curling procedure to pull while rotating ) Is preferably formed to have a curved surface to perform a smooth procedure while pressing the hair (H) locally without damage.

In addition, the groove 72b formed between each of the protrusions 71a serves as a discharge passage for water vapor generated in the process of being heated by the adjacent protrusions 72a and indirectly radiates heat to the hair H. Provide rapid curling to induce strong curling.

The third embodiment has the same effect as the first and second embodiments described above, but in particular, the surface itself of the lower heating plate 72 has a plurality of protrusions (continuous in the width direction (the operation movement direction of the iron)) 72a) consists of a groove 72b between each protrusion 72a, so that the procedure of “heating-drying-local compression curling” of the present invention is repeatedly repeated several times in a single procedure. The curl can be formed with certainty, which is very advantageous for wave molding.

Figure 16 shows another form of a hair iron third embodiment according to the present invention, wherein the hair iron shown is provided with an upper tongue 80 and a lower tongue 70, but only the lower tongue 70 is opened. This is to be supplied as the lower tongue itself in the form of a tube to form a hot plate.

Therefore, since the lower hot plate 72 formed by the lower tongue 70 has a cylindrical shape, an inner circumferential surface of the lower hot plate 72 forms an inner surface of the upper tongue 80 that contacts the surface of the lower hot plate 72. A curved surface corresponding to the curved surface is formed.

On the surface of the lower hot plate 72, as in the above-described third embodiment, a plurality of grooves 72b are continuously spaced apart in the radial direction thereof on the surface, such that the plurality of protrusions 72a are repeatedly provided on the surface. Configuration.

That is, the plurality of protrusions 72a and the recesses 72b are formed on the surface of the lower heating plate 72 in the longitudinal direction.

At this time, each of the protrusions (72a) is preferably formed in a curved surface so as to be continuously repeated in the same size, to locally compress the hair (H) without damage.

In addition, the groove 72b formed between each of the protrusions 71a serves as a discharge passage for water vapor generated in the process of being heated by the adjacent protrusions 72a and indirectly radiates heat to the hair H. To facilitate rapid drying and to reduce the area of hair contacting the hotplate to minimize damage to the hair due to contact with the hotplate.

In particular, the surface of the lower heating plate 72 shown in FIGS. 16 and 17 is composed of a plurality of protrusions 72a which are continuously repeated, and has grooves 72b between each of the protrusions 72a. The procedure of "Local Compression Curling" is repeated continuously in one procedure, which makes it possible to form curls very stably and reliably.
