By making it contact with the bottom face of 41, the rotation to the close direction of the upper arm part 2 and the lower arm part 3 is controlled.

  Furthermore, in the present embodiment, the hair iron device 100 includes the upper arm portion 2 and the lower side when the upper arm portion 2 and the lower arm portion 3 are restricted from rotating in the closing direction (restricted by a restriction member). Variable means for changing the angle formed by the arm portion 3 (relative position with respect to the lower holding portion 3b of the upper holding portion 2b) is provided.

  Specifically, as shown in FIG. 7, a slide member 50 is provided in the case 30 so as to be slidable in the longitudinal direction of the case 30, and the groove depth of the stopper groove 41 is changed by sliding the slide member 50. ing.

  In the present embodiment, a through hole 30k is provided in the top wall 30c, and a groove 51 having a bottom surface 50b is provided on the upper surface 50a of the slide member 50. Then, by sliding the slide member 50, as shown in FIG. 7A, the upper surface 50a closes the lower opening of the through hole 30k, and as shown in FIG. 7B, the through hole 30k The state in which the groove 51 is communicated can be switched.

  Thus, in the present embodiment, a shallow groove is formed by the through hole 30k and the upper surface 50a, and a deep groove is formed by the through hole 30k and the groove portion 51, thereby changing the depth of the stopper groove portion 41. ing.

  Further, in the present embodiment, the depth of the stopper groove 41 can be changed in conjunction with the attachment and detachment to the lower holding portion 3b of the set member 10. Specifically, as shown in FIGS. 9, 11, and 13, the slide member 50 is integrally provided with a slide plate 52 that is pressed by the set member 10 and slides backward through a connecting arm 53.

When the set member 10 is mounted on the lower holding portion 3b, the rear end surface 10g of the set member 10 abuts on the front end surface 52a of the slide plate 52 during the mounting, and the set member 10 slides backward. At the same time, the slide plate 52 is pressed backward, and the slide member 50 slides backward. When the set member 10 is mounted on the lower holding portion 3b, the slide member 50 slides to the position shown in FIG. 7B, and the through hole 30k and the groove portion 51 are in communication with each other.

  The slide member 50 is urged forward by an urging member (not shown). When the set member 10 is removed from the lower clamping portion 3b, the slide member 50 moves forward and is in a state shown in FIG. A state where a shallow groove is formed by the through hole 30k and the upper surface 50a.

  As described above, in this embodiment, when curling the hair H using the set member 10, the depth of the stopper groove 41 is increased, and the hair H is curled without using the set member 10. When attaching, the depth of the stopper groove 41 is made shallow so that the amount of hair pinching, the pressure applied to the hair, and the like can be made to be in a more suitable state depending on the application.

  Specifically, when the depth of the stopper groove 41 is increased, the stopper groove 41 is set so that it can be rotated until the state shown in FIG. 4B is reached, and the upper hair holding surface 22a and the lower hair holding surface are set. It is set so that the hair H sandwiched between 32a is pressed against the curved surface 32d by the protrusion 20c and, when shallow, the rotation in the closing direction is restricted in the state shown in FIG. Thus, the hair H is pressed with an appropriate pressure. The depth of the groove is not limited to this and can be set as appropriate.

  In addition, it is preferable that the hair holding surfaces 22a and 32a have a photocatalytic function. For example, as shown in FIG. 14, coating materials 22b and 32b containing photocatalyst particles are applied and coated on the surfaces of the plate portion 22 and plate portion 32. As shown in FIG. 15, the photocatalyst particles 22c and 32c are By making it contain in the plate part 22 and the plate part 32, the photocatalytic function can be given to the hair clamping surfaces 22a and 32a.

  A known material such as silver can be used as a material for causing the hair holding surfaces 22a and 32a to exhibit a photocatalytic function, and it is particularly preferable to use titanium dioxide. As described above, by using titanium dioxide, the hair holding surfaces 22a and 32a can be provided with a hydrophilic function by the titanium dioxide, so that the hair can be given a moist and smooth feeling.

  Here, the effect | action at the time of using the hair iron apparatus 100 with which the set member 10 was mounted | worn is demonstrated.

  First, the set member 10 is mounted, and the depth of the stopper groove 41 is increased so that the upper arm 2 and the lower arm 3 can be rotated until the state shown in FIG. . And the upper hair clamping surface 22a and the lower hair clamping surface 32a are heated so that it may become predetermined temperature.

  Then, in the state where the hair H is arranged so as to extend in the width direction of the upper clamping part 2b and the lower clamping part 3b between the upper clamping part 2b and the lower clamping part 3b opposed to each other, the upper hair The hair H is sandwiched between the clamping surface 22a and the lower hair clamping surface 32a. At this time, the case 20 moves relative to the case 30 downward, and the hair H is pressed downward by the protrusions 20c and pressed against the heated curved surface 32d. In this way, by pressing the hair H against the heated curved surface 32d, curled brazing can be applied to the hair H in which the hydrogen bonds between the hair fibers are cut, so the hair H can be easily curled. Can be brazed. Furthermore, since the hair fibers can be hydrogen-bonded in a state where the hair H is curled, the curl retention of the hair H can be increased.

  Next, the hair iron device 100 is rotated halfway in a state where the hair H is sandwiched so that the hair H on the root side that is not sandwiched between the upper hair sandwiching surface 22a and the lower hair sandwiching surface 32a is curled on the set member 10 Press against 10e. Then, in a state where the hair H is pressed against the curled portion 10e of the set member 10, the hair iron device 100 is pulled down toward the hair tip while sliding along the hair H, so that curled wrinkles are formed on the hair H. Affixed.

For this reason, the hair H can be pushed toward the lower clamping part (second clamping part) 3b by the protrusion 20c. As a result, before the hair H is pressed against the set member 10 to be brazed, the hair H can be brazed by the protrusions 20c, and the hair H can be brazed more reliably. it can. Thus, according to this embodiment, the hair H can be hair-styled to a desired shape more reliably.

  In addition, according to the present embodiment, in the state where the hair H is sandwiched between the upper hair clamping surface (first hair clamping surface) 22a and the lower hair clamping surface (second hair clamping surface) 32a, the upper clamping unit A protrusion 20c is provided along the longitudinal direction (direction intersecting with the extending direction of the hair) at the end of the (first holding portion) 2b in the width direction (the extending direction of the inserted hair). Therefore, when the hair H is pinched by the upper hair holding surface (first hair holding surface) 22a and the lower hair holding surface (second hair holding surface) 32a, the lower holding portion of the hair H more uniformly. (2nd clamping part) It can push to 3b side.

  In addition, according to the present embodiment, the protrusions 20c are provided at both ends of the upper clamping part (first clamping part) 2b in the width direction (extending direction of the sandwiched hair). As a result, it becomes unnecessary to consider the direction of the tip of the hair H when pinching, and the usability of the hair iron 1 can be improved.

  In addition, according to the present embodiment, since the top of the protrusion 20c has a substantially arc shape, the hair H is sandwiched between the protrusion 20c and the lower hair clamping surface (second hair clamping surface) 32a. In addition, the load applied to the hair H can be reduced, and damage to the hair H can be reduced.

  In addition, according to the present embodiment, the hair clamping member 21 can be reciprocated relative to the case (clamping body) 20 relative to the normal direction of the upper hair clamping surface (first hair clamping surface) 22a.

Thus, by allowing the upper hair holding surface (first hair holding surface) 22a to move, the upper hair holding surface (first hair holding surface) 22a and the lower hair holding surface (second hair) It is possible to suppress an excessive load on the hair H sandwiched between the sandwiching surface) 32a and to prevent damage to the hair H. In addition, by moving the hair clamping member 21 relative to the normal direction of the upper hair clamping surface (first hair clamping surface) 22a, the top of the protrusion 20c and the upper hair clamping surface (first hair clamping surface) Since the step is formed with the surface 22a, the hair H can be brazed more reliably.

  In addition, according to the present embodiment, the lower hair holding portion (second holding portion) 2b is disposed so that the lower hair holding surface (second hair holding surface) 32a faces upward, and the upper hair holding portion is held. When the hair H is sandwiched between the surface (first hair clamping surface) 22a and the lower hair clamping surface (second hair clamping surface) 32a, the lower hair clamping surface (second hair clamping surface) 32a It can be arranged above the top of the protrusion 20c. Therefore, the hair H can be brazed between the top of the protrusion 20c and the upper hair clamping surface (first hair clamping surface) 22a, and the hair H can be brazed more reliably. become able to.

  By the way, when brazing hair H, thermal energy is applied to hair, hydrogen bonds between hair fibers are cut, and in that state, hair H is shaped into a desired shape (for example, curled shape). In this state, it is preferable that the hair H be held in a desired shape by depriving the heat energy and hydrogen bonding the hair fibers again.

  However, in the above-described prior art, the hair that is heated by being sandwiched between the heat generating portions is cooled until it comes into contact with the curled portion, and when pressed against the curled portion, the hair fibers are recombined by hydrogen bonding. There was a fear. Thus, when the hair in a state where the hair fibers are hydrogen-bonded is pressed against the curled portion, it is difficult to arrange the hair into a desired shape.

  On the other hand, in this embodiment, a heater that heats the hair H sandwiched between the upper hair clamping surface (first hair clamping surface) 22a and the lower hair clamping surface (second hair clamping surface) 32a ( By providing the heat generating portions) 23 and 33, the hair H in a state where the thermal energy is applied and the hydrogen bonds between the hair fibers are cut off, the lower holding portion (second holding portion) 3b side by the protrusion 20c Can be pushed to. Therefore, the hair H can be brazed more reliably.

  In addition, in the present embodiment, the hair H sandwiched between the upper hair clamping surface 22a and the lower hair clamping surface 32a is pressed against the curved surface 32d by the protrusion 20c, so that the hair H is more reliably brazed. Will be able to.

Therefore, the thickness of the hair iron device 100 can be reduced.

  In addition, since the set member is installed only in the lower holding portion (second holding portion) 3b, the set member can be easily replaced, the number of parts can be reduced, and the configuration can be simplified. It becomes possible. Moreover, since the hair H can be brazed only by half-turning the hair iron apparatus 100, the usability of the hair iron apparatus 100 can be improved.

  Further, according to the present embodiment, the curl portion 10e of the set member 10 in a state where it is mounted on the lower clamping portion (second clamping portion) 3b, lowers the lower clamping portion (second clamping portion) 3b.
