Description

  The present invention relates to a hair iron.

  Conventionally, various hair irons have been proposed. For example, the portable hair management device described in Patent Document 1 includes a direct current power source, a heat transfer hollow tube, and a light bulb for generating heat to transfer heat to the hollow tube. The bulb is preferably a halogen and further includes a control circuit for the device to reach and maintain the desired temperature.

In such a portable hair management apparatus, a battery is used to supply power to the apparatus.

Special table 2007-522874

  However, the portable hair management device described in Patent Document 1 has several problems.

  First, as a fundamental problem, it is assumed that driving with a battery is almost impossible. That is, when the halogen proposed as a heat source is to be warmed up to a predetermined temperature by the battery power source, it is necessary to drive the battery beyond its capacity limit, and the battery becomes very hot.

  In addition, when a halogen lamp is installed as a heat source inside the hollow tube, it is necessary to install an air layer sandwiched between the heat conducting member due to the influence of glass breakage or the like. As a result, the conduction heat transfer efficiency is greatly reduced, and actually it takes a lot of time to warm the heat conduction member to a desired temperature. For this reason, it should be a method that uses light radiation (radiation) heating instead of small holes like perforations, and should work directly on hair moisture to increase temperature and significantly reduce time. .

  Moreover, since the frictional stress and thermal stress by a heat conductive base material are received simultaneously at the time of hair treatment, it has the subject that the damage degree of hair becomes large.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a hair iron that can easily perform hair treatment while suppressing hair stress.

  The present invention provides a hair iron that holds hair between a first holding portion and a second holding portion, and that does not contact hair with at least one of the first holding portion and the second holding portion. And a hair holding part for holding hair that has been heated in a non-contact manner by the heating part and brought into a correctable state.

  Moreover, in this invention, you may provide the reflection part which reflects light in the side facing the said heating part among the said 1st clamping part and the said 2nd clamping part.

  Moreover, in this invention, the coating which reacts to a predetermined wavelength may be given to the outer surface of the said heating part.

  Moreover, in this invention, the longitudinal direction front-end | tip of the said heating part may face the hair nipping surface side.

  Moreover, in this invention, the reinforced member may be inserted in the outer surface glass of the said heating part.

  In the present invention, the heating unit holding unit that holds the heating unit may include an elastic structure.

  In this invention, the heating part which heats hair non-contactingly is provided, and the hair holding part which hold | maintains the hair which became the state which can be corrected by heating non-contactingly by the heating part is provided. Thereby, it is possible to provide the hair iron which can perform hair treatment simply, suppressing hair stress.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

(First embodiment)
Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  As shown in the perspective view of FIG. 1 and the side view of FIG. 2, the hair iron 1 according to the present embodiment includes an upper arm portion 2 that is connected so as to be expanded in a substantially V shape via a rotation connecting portion 4. And a lower arm portion 3. By relatively rotating the upper arm portion 2 and the lower arm portion 3 via the rotation connecting portion 4, the tips of the upper arm portion 2 and the lower arm portion 3 can be brought into contact with and separated from each other.

  An upper gripping portion (first gripping portion) 2a and a lower gripping portion (second gripping portion) are provided on the rotation connecting portion 4 side of the upper arm portion 2 and the lower arm portion 3 (rear side of the hair iron 1). ) 3a is provided. On the other hand, an upper clamping part (first clamping part) 2b and a lower clamping part (second clamping part) 3b are provided on the distal end side of the hair iron 1, respectively. A surface that can be contacted when the upper arm portion 2 and the lower arm portion 3 are closed will be referred to as a hair holding surface 94.

  Curled portions 2d and 3d for curling hair are provided on the outer surfaces on the back side of the upper clamping portion 2b and the lower clamping portion 3b. Although details will be described later, the upper clamping unit 2b and the lower clamping unit 3b are provided with a heating unit 90 for heating the hair in a non-contact manner. The hair that has been heated in a non-contact manner by the heating unit 90 and is ready for correction is pinched by the hair holding unit 91, and the hair is crushed by being compressed or pulled.

  Various electrical components are accommodated in the upper arm portion 2 and the lower arm portion 3. For example, a control circuit for controlling the temperature or the like of the heating unit 90 is accommodated, and the heating unit 90 is connected to the control circuit via a lead wire. In addition, an operation switch is provided on the lower grip 3a side, and the operation of the heating unit 90 can be switched on and off by operating this operation switch. In addition, although various electric parts, such as an ion generator, a ventilation fan, and a thermistor, are accommodated, detailed description is abbreviate | omitted here.

  FIG. 3 is a cross-sectional view of the hair iron 1 according to the first embodiment. As shown in this figure, a heating part 90 is fixed by a fixing part 93 at a substantially central part of the upper holding part 2b and the lower holding part 3b. A hair holding part 91 is provided on both outer sides of the heating part 90, and the hair is held by the hair holding part 91 from above and below. The heating part 90 should just exist in at least one of the upper side clamping part 2b and the lower side clamping part 3b. There may be a pair of hair holding portions 91 at opposite positions on the hair holding surface 94.

  The heating unit 90 is a light heater, LED, PTC heater or the like that heats hair in a non-contact manner. “Heating in a non-contact manner” means heating directly without using a conventional heat conducting member. The light heater applies to the hair the hair straightening energy (for example, hair intermolecular bond cutting energy) necessary to obtain the desired hair shape. As the light heater, a halogen heater that efficiently expresses the hair straightening energy wavelength is preferable, but various heaters such as a carbon heater and a quartz heater can be employed. At that time, it is important to express the far-red and near-red wavelengths as much as possible.

  There are two main methods for obtaining hair straightening energy. One is a method of obtaining a wavelength that directly acts on intermolecular bond breaking. The other is a method of acting on the hair absorption wavelength such as moisture inside the hair to promote the generation of thermal energy and indirectly acting on the intermolecular bond breaking. Both work on the infrared region. An LED or the like that can effectively produce a specific wavelength band that generates these bond breakage or recombination promoting wavelengths is convenient and excellent in terms of safety and structure.

  Infrared rays are roughly classified into near infrared rays, medium infrared rays, and far infrared rays, and high efficiency can be achieved by using advantageous effects at each wavelength. For example, near-infrared rays that are susceptible to skin tissue reaction are dominant for internal penetration of skin and the like. As for the action on the human body surface, far infrared rays which have a high water absorbance and are easy to react with surface water are dominant.

  Halogen light is advantageous in that it works on hair moisture and internal tissues because it has a wide range of near infrared 1.0 μm to far infrared 30 μm and high light intensity. In order to make it act only on hair locally, it is more effective to take out only a specific wavelength of 3 μm to 30 μm among the halogen light wavelengths. Thereby, the effect | action on skin etc. can be suppressed and it becomes possible to take out the effect | action only to hair. In particular, LED and light source cut using only specific wavelengths of 4 μm, 5.7 μm, and 7 μm are effective.

  In FIG. 3, although the structure provided with the heating part 90 in both the upper side clamping part 2b and the lower side clamping part 3b is illustrated, this invention is not limited to this. For example, as shown in FIG. 4, the heating unit 90 may be provided only in the upper holding portion 2 b. Or as shown in FIG. 5, it is also possible to provide the heating part 90 of 2 rows in the lower side clamping part 3b. In this case, by providing the hair holding unit 91 between the two rows of heating units 90, it is possible to more reliably avoid the problem that the hair contacts the heating unit 90. In addition, as shown in FIG. 6, an elastic spring 95 may be provided between the outer housing that forms the outer portion of the upper holding portion 2 b and the hair holding portion 91, and the hair holding portion 91 may be elastically driven. Furthermore, although illustration is abbreviate | omitted, the hair clamping surface 94 side of the heating part 90 may be covered with the transparent cover or the mesh.

  The hair holding unit 91 holds the hair that has been ready for correction by receiving the hair correction energy. As for the material, shape, and structure of the hair holding portion 91, it is appropriate to adopt a material that is not easily subjected to hair friction stress. For example, a highly slidable material (fluorine, Teflon (registered trademark)) having a small surface friction resistance that is elastically driven, a material having a low surface roughness, a coating, and the like can be given. Moreover, it is good to comprise with materials (wood, plasticity, etc.) with low heat conductivity as much as possible.

  The hair holding portion 91 has a shape protruding from the light heater toward the hair holding surface 94 side. Thereby, since possibility that hair touches a light heater directly can be excluded, it becomes possible to suppress that unexpected light heater heat is applied to hair. Further, assuming that the hair holding portion 91 may be elastically driven, a structure in which the top of the hair holding portion 91 protrudes from the light heater to the hair holding surface 94 side even when the elastic driving bottom dead center is reached. Keep it. The shape of the hair holding part 91 is preferably a protrusion. The stress per unit area becomes higher with respect to the pinching force of the same user than the surface contact, and the hair shape correction performance is improved. When the user applies more pinching force than necessary, user discomfort can be eliminated by elastic driving. The hair holding part 91 may have a cooling function. In that case, since warm addition and cold addition can be implemented, the hair treatment effect is further improved by rapid thermal cooling. Further, when the hair holding unit 91 is cooled, the hair holding unit 91 can be brought closer to the base of the hair.

  A series of operation | movement at the time of using the hair iron 1 of such a structure is demonstrated.

  First, the hair inserted between the hair holding surfaces 94 is sandwiched between a pair of hair holding portions 91. At this time, since a light heater is installed in a portion other than the hair holding portion 91, the hair in that portion receives the hair straightening energy from the light heater and becomes ready for softening correction. Therefore, when the hair is pressed against the curled portion 2d or the curled portion 3d and the hair iron 1 is pulled down toward the hair tip while sliding along the hair, curled brazing is applied to the hair. If the hair iron 1 is pulled down toward the end of the hair while sliding along the hair without rotating, it is possible to give a straight brazing to the hair. As described above, the hair inserted between the hair holding surfaces 94 is given an environment where the treatment can be performed by the light heater, and an environment where the hair can be straightened is given by the hair holding unit 91.

  As described above, the present embodiment includes the heating unit 90 that heats the hair in a non-contact manner, and the hair holding unit 91 that holds the hair that has been heated in a non-contact manner by the heating unit 90 and is in a correctable state. ing. Thereby, since the radiant energy of the heating part 90 can be used efficiently, non-contact type hair correction becomes possible and the simultaneous load of hair stress, especially thermal stress and friction stress can be suppressed. In addition, since the radiation energy is directly used to act on the hair, it is not necessary to warm up the heat conductive base material, and the treatment time can be shortened.

  Furthermore, since the kind of light heater can be selected appropriately and the energy of the light heater can be used efficiently, the required energy efficiency is also increased. In addition, taking advantage of the radiation characteristic of the light heater, it is absorbed by the hair and not absorbed by other parts (such as the body), so the body temperature rise that was a problem with conventional hair heating devices Etc. can be avoided.

(Second Embodiment)
FIG. 7 is a cross-sectional view of the hair iron 1 according to the second embodiment. As shown in FIG. 7, the hair iron 1 includes a heating unit 90 in the upper holding portion 2b and a reflecting portion 96 in the lower holding portion 3b. Thereby, it becomes possible to supply light radiation energy to hair effectively, and it is possible to realize a reduction in W of the light heater and an increase in energy efficiency.

  In order to effectively exhibit the function of the reflecting part 96, it is important to prevent external leakage of light as much as possible during the treatment. Therefore, it is preferable to install the reflecting portion 96 in a range surrounded by the hair holding portion 91 and the hair holding surface 94. When it is installed on either one, the light condensing effect or the diffusion effect is efficiently added to the reflecting portion 96. As the structure of the reflecting portion 96, a structure using a facet shape is more effective. Suitable materials are SiO2, Al2O3, and the like.

  Consideration of light distribution in the light heater is important. By installing the reflection part 96, the light energy to hair can be raised more. At that time, the balance between light collection and diffusion is important, and is considered depending on the installation method and installation arrangement of the light heater. When installing the reflection part 96 in one of the upper side holding part 2b and the lower side holding part 3b, it is better to install it in the side facing the optical heater installation side. This is for ensuring the supply of light energy to the hair on the counter electrode side that does not receive direct light energy with respect to the light energy supply to the hair on the side facing the light heater. Of course, as shown in FIG. 8, the reflection part 96 may be provided in both the upper holding part 2b and the lower holding part 3b. In this case, the fixing portion 93 of the heating unit 90 can have a reflection function.

  As described above, in the present embodiment, since the reflection unit 96 that reflects light is provided on the side facing the heating unit 90, it is possible to increase the efficiency of adding light energy to the hair. As a result, efficient light energy supply can be achieved, and low W can be achieved.

(Third embodiment)
In the hair iron 1 according to the third embodiment, the outer surface of the heating unit 90 is coated with a coating that reacts to a predetermined wavelength. The functions required for coating are roughly divided into two types. One is a type that exhibits an accelerating reaction with respect to the wavelength expressed by the light heater, and the other is a type that aims to cut an unnecessary wavelength with respect to the wavelength expressed by the light heater. . In the case of the former, what has the characteristic which responds to near infrared rays, far infrared rays, etc. mainly, such as a tourmaline paint, is good. In the latter case, it is preferable to have a characteristic of transmitting far-red to near-infrared wavelengths that are generally easily absorbed by the human body and not transmitting other wavelengths to the outside. Of course, a coating may be applied not only to the surface of the light heater but also to the entire hair holding surface 94.

  As described above, in the present embodiment, a coating that reacts to a predetermined wavelength is applied to the outer surface of the heating unit 90. Therefore, not only the characteristic unique to the light heater but also other characteristics can be applied to the hair, so that the necessary action on the hair can be expanded and unnecessary action can be blocked. That is, it becomes possible to further enhance the far-red effect and to prevent unnecessary excessive stress (such as heat stress).

(Fourth embodiment)
FIG. 9 is a cross-sectional view of the hair iron 1 according to the fourth embodiment. In this hair iron 1, as shown in FIG. 9, the front-end | tip of the longitudinal direction of the heating part 90 has faced the hair nipping surface 94 side. As a result, the highest strength side such as quartz glass constituting the outer shell of the light heater is exposed, and it is possible to suppress the influence such as glass breakage which is a concern with a halogen lamp or the like. With respect to the light emitting action, it is possible to compensate for high efficiency by using the internal filament shape and reflector setting.

  As described above, in the present embodiment, the longitudinal tip of the heating unit 90 faces the hair holding surface 94 side. Therefore, it is possible to install a portion having high strength against the risk of glass breakage or the like on the hair holding surface 94 side.

(Fifth embodiment)
FIG. 10 is a cross-sectional view of the hair iron 1 according to the fifth embodiment. In this hair iron 1, as shown in FIG. 10, a reinforcing member 97 is inserted into the outer surface glass of the heating unit 90. If a linear reinforcing member such as a wire is employed as the reinforcing member 97, the light heater component strength can be increased without affecting the light heater light distribution, light intensity, or the like.

  As described above, in this embodiment, the reinforcing member 97 is inserted into the outer glass of the heating unit 90. Thereby, it is possible to reduce the risk of breakage of the outer surface glass of the heating unit 90 and to reduce the risk of scattering at the time of breakage.

(Sixth embodiment)
FIG. 11 is a cross-sectional view of the hair iron 1 according to the sixth embodiment. In this hair iron 1, as shown in FIG. 11, the heating part holding | maintenance part 98 holding the heating part 90 is provided with the elastic structure. Specifically, a spring or rubber material is employed as an elastic function for the power supply connector of the optical heater. Thereby, the impact etc. in use can be attenuated. Such a damping mechanism can be configured so as to be able to cope with the longitudinal axis direction as well as the short axis direction.

  As described above, in the present embodiment, the heating unit holding unit 98 that holds the heating unit 90 includes an elastic structure. Thereby, glass breakage can be suppressed against excessive impact such as impact, vibration or drop during use, and damage to the internal structure can also be suppressed.

  In addition, although preferred embodiment was described above, this invention is not limited to the said embodiment, A various deformation | transformation is possible. For example, in FIG. 1, the plurality of heating units 90 are arranged vertically, but as shown in FIG. 12, only one columnar heating unit 90 may be installed horizontally. In addition, the specifications (shape, size, layout, etc.) of the heating unit 90 and the hair holding unit 91 can be changed as appropriate.
