Description

Technical Field

[0001] The present disclosure relates to a hair curler. Background Art

[0002] In the past, for example, Japanese Patent Publication No. 2018-102540 (hereinafter referred to as "Patent Document 1") disclosed a hair curler comprising: a first hair clamping portion having a first hair clamping surface; and a second hair clamping portion having a second hair clamping surface that can be opposite to the first hair clamping surface.

[0003] The hair iron disclosed in Patent Document 1 is a device that performs hair care by clamping hair in a state where a first hair clamping surface and a second hair clamping surface are opposed to each other.

[0004] Furthermore, the hair iron of Patent Document 1 includes a discharge device for generating ions and an ion emission port capable of emitting the ions generated by the discharge device toward the hair. This can further improve the hair care effect of the hair iron.

[0005] However, the above-mentioned conventional hair iron arranges the discharge device at a portion overlapping with the first hair clamping surface. Specifically, when viewed along the normal direction of the first hair clamping surface, the discharge device is arranged at a position where the discharge device and the first hair clamping surface overlap. Therefore, the thickness of the hair iron (the dimension in the normal direction of the first hair clamping surface) may become larger. Summary of the invention

[0006] The present invention provides a hair iron capable of improving the hair care effect and achieving miniaturization in the thickness direction.

[0007] The hair iron of the present disclosure includes: a first hair clamping portion having a first hair clamping surface; and a second hair clamping portion having a second hair clamping surface that can be opposite to the first hair clamping surface. In addition, the hair iron clamps hair in a state where the first hair clamping surface and the second hair clamping surface are opposite to each other. In addition, the hair iron also includes a discharge device for generating ions and an ion discharge port for discharging ions generated in the discharge device. In addition, the discharge device is arranged in a portion of the first hair clamping portion that does not overlap with the first hair clamping surface.

[0008] According to the present disclosure, it is possible to provide a hair iron that can improve the hair care effect and achieve miniaturization in the thickness direction. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] Hereinafter, the embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. In addition, in the following description, the vertical direction is defined based on the hair iron in a state where the first hair clamping surface and the second hair clamping surface are close to each other (the first hair clamping portion and the second hair clamping portion are closed) and the first hair clamping surface is located above the second hair clamping surface. In addition, the description is given with the hair clamping portion side of the hair iron being the front and the gripping portion side of the hair iron being the rear.

[0025] Furthermore, the description will be given with the front-rear direction (the length direction of the first hair holding surface and the second hair holding surface) under the above reference being the X direction, the width direction (the width direction of the first hair holding surface and the second hair holding surface) under the above reference being the Y direction, and the up-down direction (the thickness direction of the first hair holding portion and the second hair holding portion under the above reference) under the above reference being the Z direction.

[0026] (Implementation Method)

[0027] Below, refer to Figure 1 to Figure 4 A schematic structure of the hair iron 10 according to the embodiment of the present disclosure will be described.

[0028] like Figure 1 to Figure 4 As shown, the hair iron 10 of this embodiment includes a first arm 20A (upper arm) and a second arm 20B (lower arm), and the first arm 20A and the second arm 20B are connected to each other via a rotation connection portion 110 so as to be able to be opened into a substantially V-shape (including the V-shape). The first arm 20A and the second arm 20B are relatively rotated via the rotation connection portion 110. Thus, the hair iron 10 is configured so that the top end of the first arm 20A and the top end of the second arm 20B can contact / separate from each other.

[0029] That is, the hair iron 10 of this embodiment is configured so that the first arm 20A and the second arm 20B can rotate relative to each other, thereby making it possible to move the first hair holding surface 560A and the second hair holding surface 560B described later closer to or farther from each other.

[0030] Next, refer to Figure 5 The rotation connection portion 110 of the hair iron 10 will be described.

[0031] like Figure 5 As shown, the rotation coupling portion 110 includes a shaft 111 having a head portion 111 a and a shaft portion 111 b , a screw 112 threadedly engaged with the shaft portion 111 b , and a shaft cover 113 covering the head portion of the screw 112 .

[0032] The rotation connection part 110 includes a pair of protrusions 114, which are formed at the rear end of the first housing 210A of the first arm part 20A described later in the X direction (front-back direction). In addition, in the present embodiment, the pair of protrusions 114 are substantially disk-shaped (including disk-shaped), and the protrusions 114 are formed in a manner protruding downward from both ends of the first housing 210A in the Y direction (width direction). A through hole 114a is formed in the center of the protrusion 114 and penetrates in the Y direction (width direction).

[0033] The rotation connection part 110 includes a protrusion 115 formed at the rear end of the second housing 210B of the second arm part 20B described later in the X direction (front-back direction). In addition, in the present embodiment, the protrusion 115 is formed in a substantially cylindrical shape (including a cylindrical shape) and is formed so as to protrude upward from the second housing 210B. A through hole 115a is formed in the center of the protrusion 115 and penetrates in the Y direction (width direction).

[0034] Furthermore, the rotation coupling portion 110 includes a coil spring 116. The coil spring 116 is accommodated in a space portion formed in the protrusion 115 having a substantially cylindrical shape (including a cylindrical shape).

[0035] The rotation connection part 110 having the above-mentioned structure is formed by, for example, the following method.

[0036] Specifically, first, the coil spring 116 is arranged in the space of the protrusion 115 .

[0037] Next, a pair of protrusions 114 are disposed at both ends of the protrusion 115 in the Y direction (width direction). At this time, the through hole 114a and the through hole 115a communicate with each other in the Y direction (width direction).

[0038] Next, the shaft portion 111 b of the shaft 111 is inserted from one side in the Y direction (width direction) through the through hole 114 a and the through hole 115 a that communicate in the Y direction (width direction).

[0039] Next, the screw 112 is passed through the through hole 114 a and the through hole 115 a from the other side in the Y direction (width direction), and is threadedly engaged with the shaft portion 111 b of the shaft 111 .

[0040] Next, the shaft cover 113 is attached from the other side in the Y direction (width direction). Thus, the head of the screw 112 is covered by the shaft cover 113 so as not to be exposed to the outside.

[0041] As described above, the first arm portion 20A and the second arm portion 20B are configured to be relatively rotatable via the rotation coupling portion 110 .

[0042] At this time, the coil spring 116 urges the first arm portion 20A and the second arm portion 20B in directions in which they are separated from each other.

[0043] Below, refer to Figure 5 The locking mechanism 120 of the hair iron 10 will be described.

[0044] like Figure 6 As shown, the hair iron 10 of this embodiment has a locking mechanism 120 disposed at the rear end portion 10a. The first arm portion 20A and the second arm portion 20B are restricted from rotating in the opening direction by operating the locking mechanism 120. Alternatively, the first arm portion 20A and the second arm portion 20B are kept in a closed state by operating the locking mechanism 120.

[0045] Specifically, the locking mechanism 120 includes a sliding locking plate 121 and a limiting protrusion 122. The sliding locking plate 121 is mounted at the rear end of the upper portion of the second housing 210B in a manner that allows sliding along the X direction (front-rear direction). The limiting protrusion 122 is formed at the front end of the sliding locking plate 121 in a manner that protrudes upward (in the Z direction).

[0046] Furthermore, the lock mechanism 120 includes a restriction recess 123 formed at the rear end of the lower portion of the first housing 210A and a restriction protrusion 124 formed at the front side of the restriction recess 123 .

[0047] The restriction recess 123 is formed so as to face the restriction protrusion 122 of the slide lock plate 121 after the slide lock plate 121 is slid rearward in the X direction (front-rear direction).

[0048] Furthermore, the restriction protrusion 124 is formed so as to face the restriction protrusion 122 of the slide lock plate 121 after the slide lock plate 121 is slid forward in the X direction (front-rear direction).

[0049] That is, when the slide lock plate 121 is slid forward, the lower end of the restricting protrusion 124 abuts against the upper end of the restricting protrusion 122 of the slide lock plate 121. Thus, the first arm 20A and the second arm 20B are kept in a closed state.

[0050] As described above, the hair iron 10 of this embodiment attempts to open the first arm 20A and the second arm 20B relative to each other under the biasing force of the coil spring 116. However, the operation of the locking mechanism 120 can restrict the opening movement of the first arm 20A and the second arm 20B.

[0051] On the other hand, when the slide lock plate 121 of the lock mechanism 120 is slid backward, the interference with the restriction protrusion 124 is released. This allows the first arm 20A and the second arm 20B to rotate in the opening direction.

[0052] The first arm 20A and the second arm 20B rotate in the opening direction until the restriction protrusion 122 of the slide lock plate 121 engages with the restriction recess 123. Thus, further rotation of the first arm 20A and the second arm 20B in the opening direction is restricted.

[0053] Furthermore, a first gripping portion 30A (upper gripping portion) and a second gripping portion 30B (lower gripping portion) are provided on the rotation connection portion 110 side of the first arm 20A and the second arm 20B (the rear side in the X direction of the hair iron 10), respectively. A first hair clamping portion 40A (upper hair clamping portion) and a second hair clamping portion 40B (lower hair clamping portion) are provided on the top end side of the first arm 20A and the second arm 20B (the front side in the X direction of the hair iron 10), respectively.

[0054] The first hair clamping portion 40A has a first hair clamping surface 560A (upper hair clamping surface), and when the first arm portion 20A is relatively rotated relative to the second arm portion 20B, the first hair clamping surface 560A can approach or move away from the second hair clamping surface 560B (can be opposite to each other). On the other hand, the second hair clamping portion 40B has a second hair clamping surface 560B (lower hair clamping surface), and when the second arm portion 20B is relatively rotated relative to the first arm portion 20A, the second hair clamping surface 560B can approach or move away from the first hair clamping surface 560A (can be opposite to each other).

[0055] In addition, the first hair holding surface 560A and the second hair holding surface 560B of the present embodiment are formed in a substantially rectangular shape (including a rectangular shape) elongated in the X direction (front-back direction) when viewed in the Z direction (up-down direction: normal direction).

[0056] In addition, if Fig. 9 As shown, the outer surfaces 420aA and 420aB of the first hair clamping part 40A and the second hair clamping part 40B of the present embodiment are formed into a curved shape. Therefore, the hair can be easily rolled around the outer surfaces 420aA and 420aB. Thus, a curly shape can be applied to the hair.

[0057] In addition, the outer surface 420aA of the first hair clamping part 40A refers to the surface existing on the back side of the first hair clamping surface 560A among the outer surfaces of the first hair clamping part 40A. In addition, the outer surface 420aB of the second hair clamping part 40B refers to the surface existing on the back side of the second hair clamping surface 560B among the outer surfaces of the second hair clamping part 40B.

[0058] That is to say, Fig. 9 In the figure, the outer surface of the first hair clamping part 40A except the lower surface and the outer surface of the second hair clamping part 40B except the upper surface correspond to the outer surface 420aA of the first hair clamping part 40A and the outer surface 420aB of the second hair clamping part 40B, respectively.

[0059] And, if Fig. 9 As shown in FIG. 1 , the first hair holding part 40A and the second hair holding part 40B include a heater 530A and a heater 530B provided as a heat generating part.

[0060] In addition, if Figure 1 As shown, the hair iron 10 has a power cord 140 installed at the rear end 10a by means of a rotary connector 130. The power cord 140 is connected to the power cord 140 by means of a wire 581. Figure 6 The control device 340B (electrical component) for controlling the heaters 530A and 530B shown is electrically connected.

[0061] Furthermore, the hair iron 10 comprises Figure 8 Operation switch 150 is shown. Operation switch 150 can switch on / off the energization of heater 530A and heater 530B by operation of the user.

[0062] By using the hair iron 10 having the above-described structure, it is possible to give curly or straight shapes to the hair.

[0063] That is, when using the hair iron 10, the hair is first clamped by the first hair clamping surface 560A and the second hair clamping surface 560B. Then, the heat generated by the heater 530A and the heater 530B is applied to the hair via the first hair clamping surface 560A and the second hair clamping surface 560B. Thus, the hair can be shaped into a curly or straight shape.

[0064] Specifically, for example, curly styling is performed on the hair as follows.

[0065] First, the heated first hair clamping part 40A and the second hair clamping part 40B are made to face each other. Then, hair is arranged between the first hair clamping part 40A and the second hair clamping part 40B in a manner extending along the width direction (Y direction) of the first hair clamping part 40A and the second hair clamping part 40B. In this state, the hair is clamped by the first hair clamping surface 560A and the second hair clamping surface 560B.

[0066] Next, the hair iron 10 is rotated, for example, with the X direction as the rotation axis, while the hair is clamped. Thus, the hair on the hair root side that is not clamped by the first hair clamping surface 560A and the second hair clamping surface 560B is pressed against the outer surface 420aA of the first hair clamping part 40A or the outer surface 420aB of the second hair clamping part 40B. Then, while the hair is pressed against the outer surface 420aA or the outer surface 420aB, the hair iron 10 is slid along the hair and pulled down toward the hair tip. Thus, a curly shape is applied to the hair.

[0067] On the other hand, the hair is styled straight as follows.

[0068] First, the hair is clamped by the first hair clamping surface 560A and the second hair clamping surface 560B. In this state, the hair iron 10 is not rotated but slid along the hair and pulled down toward the hair tip. Thus, a straight shape is applied to the hair.

[0069] That is, the hair iron 10 of the present embodiment performs hair styling by applying a shape to the hair by heat.

[0070] Hereinafter, the above-mentioned first arm portion 20A will be described in more detail.

[0071] like Figure 1 As shown, the first arm portion 20A mainly includes a first housing 210A forming an outer wall. Moreover, the first housing 210A on the side of the rotation connection portion 110 (the rear side in the X direction of the hair iron 10) constitutes a first gripping portion side housing 310A, and the first gripping portion side housing 310A forms the outer wall of the first gripping portion 30A. On the other hand, the top end side of the first housing 210A (the front side in the X direction of the hair iron 10) constitutes a first hair clamping portion side housing 410A, and the first hair clamping portion side housing 410A forms the outer wall of the first hair clamping portion 40A.

[0072] The first housing 210A of the present embodiment is formed in a hollow shape by covering the opening portion of the upper housing 220A that opens downward with the lower housing 230A.

[0073] Specifically, the cover 330A covers the opening portion of the upper shell 320A of the first holding portion 30A that opens downward. Thus, the first holding portion side housing 310A is formed into a hollow shape. In addition, the first hair clamping member 50A covers the opening portion of the upper shell 420A of the first hair clamping portion 40A that opens downward. Thus, the first hair clamping portion side housing 410A is formed.

[0074] As described above, the upper case 220A of the present embodiment is formed by the upper case 320A of the first gripping part 30A and the upper case 420A of the first hair clipping part 40A. On the other hand, the lower case 230A is formed by the cover 330A and the first hair clipping member 50A.

[0075] In addition, in the present embodiment, the upper shell 320A of the first gripping part 30A and the upper shell 420A of the first hair clamping part 40A are formed integrally. That is, the rotation connection part 110 side of the upper shell 220A becomes the upper shell 320A of the first gripping part 30A. On the other hand, the top end side of the upper shell 220A becomes the upper shell 420A of the first hair clamping part 40A.

[0076] The cover 330A and the first hair holding member 50A are formed separately, and the lower case 230A is formed by attaching the cover 330A and the first hair holding member 50A to cover the opening portion of the upper case 220A.

[0077] Furthermore, in this embodiment, if Figure 6 As shown, the hollow portion S1 in the first housing 210A is partitioned into a hollow portion S2 on the first gripping portion 30A side and a hollow portion S3 on the first hair clamping portion 40A side by the partition wall 240A.

[0078] The partition wall 240A includes a wall portion 221A, a wall portion 331A, and a seal 250A. The wall portion 221A is formed so as to protrude from the inner side (lower surface side) of the center portion in the X direction (length direction: front-back direction) of the upper shell 220A toward the lower side in the Z direction. The wall portion 331A is formed so as to protrude from the inner side (upper surface side) of the front side in the X direction of the cover 330A toward the upper side in the Z direction. The seal 250A is sandwiched between the wall portion 221A and the wall portion 331A. Thus, the partition wall 240A is formed.

[0079] Here, in the present embodiment, the portion of the first arm portion 20A which is further rearward than the partition wall 240A is set as the first gripping portion 30A, and the portion which is further forward than the partition wall 240A is set as the first hair clamping portion 40A. That is, in the hair iron 10 of the present embodiment, the portion on the top end side (forward than the wall portion 331A) of the cover 330A also constitutes a part of the first hair clamping portion side housing 410A.

[0080] Moreover, in Figure 6 Various electrical components are housed in the hollow portion S2 on the first gripping portion 30A side and the hollow portion S3 on the first hair clamping portion 40A side.

[0081] Specifically, in this embodiment, electronic components (electrical components) such as the control device 340A are housed in the hollow portion S2 on the first gripping portion 30A side. The discharge device 600 (electrical component), the thermostat 582A (electronic component: electrical component), etc. are housed in the hollow portion S3 on the first hair clamping portion 40A side.

[0082] The above arrangement can improve the waterproof effect of electronic components (electrical components) such as the control device 340A housed in the hollow portion S2 on the first gripping portion 30A side.

[0083] The control device 340A and the discharge device 600 (electrical component) are electrically connected by a lead wire 581 , and the lead wire 581 passes through a through hole formed in the sealing member 250A.

[0084] In addition, in this embodiment, if Figure 3 As shown in FIG. 1 , the top end 222A (the end on the front side in the X direction) of the upper shell 220A is bent toward the lower side (the first hair clamping surface 560A side). That is, by bending the top end 222A, the user can easily hold the top end 222A when using the hair iron 10. In addition, a protrusion 222aA is formed on the top end 222A. The protrusion 222aA functions as an anti-slip member when the user holds the top end 222A. In addition, the protrusion 222aA also has the function of releasing the heat conducted from the heater 530A to the top end 222A (the gripping portion for the user to hold).

[0085] Furthermore, in this embodiment, if Fig. 9 As shown, there is a heat insulating member 430A disposed on the inner surface 420bA of the upper shell 420A. The heat insulating member 430A suppresses heat conduction from the heater 530A to the upper shell 420A. In addition, the heat insulating member 430A is formed in a shape along the concave inner surface 420bA of the upper shell 420A. The heat insulating member 430A has a through hole 431A formed in a part.

[0086] On the other hand, a projection 421A that projects downward (projects toward the first hair holding member 50A) is formed at a portion corresponding to the through hole 431A.

[0087] The heat insulating member 430A is disposed on the inner surface 420bA of the upper shell 420A in a state where the protrusion 421A penetrates the through hole 431A. Thus, the heat insulating member 430A is disposed in a state where it is positioned relative to the upper shell 420A.

[0088] That is, the heat insulating member 430A is disposed on the inner surface 420bA of the upper case 420A. Thus, even when the thickness of the first hair holding part 40A is reduced, heat transfer from the heater 530A to the upper case 420A can be suppressed.

[0089] In addition, if Fig. 9 As shown, the first hair holding member 50A constituting a part of the lower case 230A includes a plate member 510A. The plate member 510A is formed of a material having high thermal conductivity, such as copper or aluminum.

[0090] The first hair clamping member 50A includes a holding member 520A and a heater 530A. The holding member 520A is supported by the upper shell 420A of the first hair clamping portion 40A and holds the plate member 510A. The heater 530A is thermally coupled to the plate member 510A and conducts the generated heat to the plate member 510A.

[0091] The plate member 510A includes a plate portion 540A that is substantially plate-shaped (including plate-shaped). The plate portion 540A has a substantially flat (including flat) first hair clamping surface 560A formed on its surface (lower surface). In the present embodiment, the first hair clamping surface 560A is formed in a substantially rectangular shape (including rectangular shape) that is elongated in the longitudinal direction of the first housing 210A when viewed from above (when viewed from the bottom).

[0092] And, if Fig. 9 As shown, both ends of the plate portion 540A in the Y direction (width direction: the same direction as the width direction of the first hair clamping portion 40A) are formed to be curved toward the inside of the first housing 210A. In addition, the first hair clamping surface 560A has curved surfaces 562A at both ends in the Y direction (width direction), and the curved surfaces 562A are formed to be convex toward the oblique outside when viewed from a width direction section (a surface obtained by cutting with a vertical plane along the width direction).

[0093] That is, the first hair holding surface 560A is composed of a flat surface 561A (flat portion) in the center in the width direction and curved surfaces 562A formed at both ends in the width direction of the flat surface 561A.

[0094] Furthermore, the plate member 510A has a pair of legs 550A on the back side (upper side) of the plate portion 540A, which are continuously provided with the plate portion 540A in a manner facing the inner side (upper side). The pair of legs 550A is held by the holding member 520A. Thus, the plate member 510A is held by the holding member 520A. Furthermore, the heater 530A is accommodated in the storage portion 570A formed between the pair of legs 550A. At this time, the heater 530A accommodated in the storage portion 570A is arranged in a manner abutting against the inner surface of the plate portion 540A.

[0095] And, if Figure 6 As shown, electrical components such as a thermostat 582A are stored on the back side (lower side) of the heater 530A in the storage portion 570A.

[0096] As the heater 530A, for example, a PTC heater (Positive Temperature Coefficient heater) can be used. By using a PTC heater, continuous temperature control can be performed. However, as a heating device, it is not necessary to use a PTC heater, for example, a nichrome wire heater or other heating devices can also be used.

[0097] In addition, if Fig. 9 As shown, the holding member 520A has a shape that is open downward, and is formed in a substantially mountain shape (including a mountain shape) that protrudes upward when viewed in cross section in the width direction.

[0098] In detail, the holding member 520A includes a top wall portion 521A, a side wall portion 522A, an upper flat portion 521aA, an inclined portion 521bA, a lower flat portion 521cA and a side wall portion 522A. The side wall portion 522A is extended downward at both ends of the top wall portion 521A in the Y direction. The upper flat portion 521aA is located in the central portion of the Y direction (width direction) and is disposed at the upper side of the top wall portion 521A. The inclined portion 521bA is continuously provided at both ends of the upper flat portion 521aA of the top wall portion 521A in the Y direction (width direction), and extends outward and downward in the Y direction. In addition, the lower flat portion 521cA is continuously provided at both ends of the inclined portion 521bA of the top wall portion 521A, and extends horizontally toward the outer side in the Y direction. Furthermore, as described above, the side wall portion 522A is provided continuously with both ends of the lower flat portion 521 cA of the top wall portion 521A in the Y direction.

[0099] In addition, it is preferable that at least one of the first hair clamping part 40A and the second hair clamping part 40B is supported to be relatively reciprocatingly movable in the up-down direction (normal direction) relative to the upper shell 420A of the first hair clamping part 40A and the lower shell 420B of the second hair clamping part 40B. According to this structure, it is possible to suppress excessive load from being applied to the hair clamped between the first hair clamping surface 560A and the second hair clamping surface 560B. As a result, it is possible to suppress damage to the hair.

[0100] Therefore, in the present embodiment, the first hair clamping portion 40A includes a first floating mechanism 60A. The first floating mechanism 60A holds the first hair clamping member 50A on the upper shell 420A (see Fig. 9 and Fig.10 ).

[0101] The first floating mechanism 60A includes two elastically deformable floating rubbers 610A (floating parts). The floating rubbers 610A are arranged in the center of the Y direction (width direction) in a state separated in the X direction (front-back direction). Moreover, the first hair clamping member 50A is relatively moved (floated) relative to the upper shell 420A by the elastic deformation of the two floating rubbers 610A.

[0102] The floating rubber 610A of this embodiment is formed in an arrow shape when viewed in cross section in the width direction, and has a neck 611A on the root side and an arrow portion 612A on the tip side. The arrow portion 612A has a shape that decreases in diameter as it goes toward the tip side, and has a flat surface 612aA with a larger area on the root side. On the other hand, the tip of the arrow portion 612A has a flat surface 612bA with a smaller area than the flat surface 612aA. In addition, the neck 611A is provided continuously with the center of the flat surface 612aA.

[0103] The neck 611A on the root side of the floating rubber 610A passes through the through hole 621A formed in the upper flat portion 521aA of the top wall portion 521A. Thus, the floating rubber 610A is held by the top wall portion 521A of the retaining member 520A. At this time, the flat surface 612aA on the root side (neck 611A side) of the arrow portion 612A is accommodated in the space 623A surrounded by the rib 622A formed on the upper flat portion 521aA of the top wall portion 521A.

[0104] On the other hand, the flat surface 612bA on the tip side (reduced diameter portion) of the arrow portion 612A is accommodated in a space 632A surrounded by a peripheral wall 631A formed on the upper portion of the protrusion 421A of the upper shell 420A.

[0105] According to the above structure, in the present embodiment, the first hair clamping member 50A is supported on the upper shell 420A by means of the elastically deformable floating rubber 610A. In other words, the first hair clamping member 50A is held on the upper shell 420A in a floating manner. Thus, the first hair clamping surface 560A can swing along the normal direction (Z direction: up and down direction) of the first hair clamping surface 560A.

[0106] In addition, the swinging of the first hair holding surface 560A along the normal direction of the first hair holding surface 560A includes the case where the first hair holding surface 560A moves parallel to the normal direction of the first hair holding surface 560A. In addition, the above-mentioned swinging also includes the case where one end of the first hair holding surface 560A moves relative to the other end of the first hair holding surface 560A along the normal direction of the first hair holding surface 560A.

[0107] That is, in the present embodiment, the swinging of the first hair holding surface 560A along the normal direction of the first hair holding surface 560A means the movement of the first hair holding surface 560A parallel to the normal direction of the first hair holding surface 560A, and the rotation of the first hair holding surface 560A around the axis along the XY plane.

[0108] And, if Fig.11 and Fig.12 As shown, the first hair holding part 40A of this embodiment includes a first rotating mechanism 70A. The first rotating mechanism 70A is configured to rotate the first hair holding surface 560A (first hair holding member 50A) around a first rotating shaft 710A extending in the X direction (front-rear direction).

[0109] Specifically, the first rotating mechanism 70A includes a first rotating piece 720A and a support portion 730A that slidably supports the first rotating piece 720A.

[0110] The first rotating piece 720A is formed on both sides of the holding member 520A in the X direction in a manner protruding outward in the X direction. The first rotating piece 720A has a shape that is curved in a manner protruding upward (in the Z direction). In addition, the concave surface 721A formed on the lower side (the first hair clamping surface 560A side) of the first rotating piece 720A is supported on the supporting portion 730A in a slidable manner.

[0111] That is, the concave curved surface 721A is formed as an arc centered on the first rotation axis 710A when viewed in cross section in the width direction (Y direction).

[0112] Here, in the present embodiment, a first groove portion 711A (groove) extending along the X direction (front-back direction: length direction) is formed in the Y direction (width direction) center portion of the first hair holding surface 560A (see Fig.13 ). The depth of the first groove 711A is, for example, about 1 mm. Moreover, the first groove 711A corresponds to the first rotation axis 710A. Therefore, in the present embodiment, the concave curved surface 721A is formed as an arc centered on the first groove 711A when viewed in cross section in the width direction.

[0113] The support portion 730A of the first rotating mechanism 70A includes two outer ribs 731A and two inner ribs 732A. The outer ribs 731A are provided at the outer side in the Y direction (width direction). The inner ribs 732A are provided at the inner side in the Y direction (width direction) of the two outer ribs 731A.

[0114] The outer rib 731A and the inner rib 732A are respectively Figure 6 The inner surface of the hollow portion S3 on the first hair holding portion 40A side of the lower shell 230A is formed so as to protrude toward the upper shell 420A.

[0115] In the present embodiment, the outer rib 731A and the inner rib 732A on one side (the rear side in the front-to-back direction) are formed on the cover 330A serving as the lower shell 230A. Furthermore, the outer rib 731A and the inner rib 732A on the other side (the front side in the front-to-back direction) are formed on a portion of the lower shell 230A covering the opening of the upper shell 220A on the front side relative to the first hair clamping member 50A.

[0116] Furthermore, in the present embodiment, the protrusion amount of the two inner ribs 732A is smaller than the protrusion amount of the two outer ribs 731A.

[0117] Furthermore, the concave surface 721A of the first rotating piece 720A is brought into sliding contact with the top ends of the two inner ribs 732A. Thus, the first rotating piece 720A is supported on the supporting portion 730A in a slidable manner. At this time, the two outer ribs 731A are configured to suppress the displacement of the first rotating piece 720A in the Y direction (width direction). Thus, when the first hair clamping surface 560A (first hair clamping member 50A) is relatively rotated relative to the upper shell 220A, the sliding contact between the concave surface 721A of the first rotating piece 720A and the top ends of the two inner ribs 732A is not released.

[0118] As described above, in this embodiment, the first rotating piece 720A is rotatably supported by the supporting portion 730A. Thus, the first hair holding surface 560A can rotate around the first groove portion 711A (first rotating shaft 710A) extending in the X direction (front-rear direction).

[0119] In addition, in the present embodiment, an example in which the first rotation axis 710A is an invisible axis has been described, but it may be a visible axis.

[0120] The first arm portion 20A is configured as described above.

[0121] Hereinafter, the second arm portion 20B described above will be described in more detail.

[0122] like Figure 2 As shown, the second arm 20B mainly includes a second housing 210B forming an outer wall. Moreover, the second housing 210B on the side of the rotation connection portion 110 (the rear side in the X direction of the hair iron 10) constitutes a second gripping portion side housing 310B, and the second gripping portion side housing 310B forms the outer wall of the second gripping portion 30B. On the other hand, the top end side of the second housing 210B (the front side in the X direction of the hair iron 10) constitutes a second hair clamping portion side housing 410B, and the second hair clamping portion side housing 410B forms the outer wall of the second hair clamping portion 40B.

[0123] The second housing 210B of the present embodiment is formed in a hollow shape by covering the opening portion of the lower shell 220B that opens upward with the upper shell 230B.

[0124] Specifically, the cover 330B is used to cover the opening portion of the lower shell 320B of the second holding part 30B that opens upward. Thus, the second holding part side housing 310B is formed into a hollow shape. In addition, the second hair clamping member 50B is used to cover the opening portion of the lower shell 420B of the second hair clamping part 40B that opens upward. Thus, the second hair clamping part side housing 410B is formed.

[0125] As described above, the lower case 220B of the present embodiment is formed by the lower case 320B of the second gripping part 30B and the lower case 420B of the second hair clipping part 40B. On the other hand, the upper case 230B is formed by the cover 330B and the second hair clipping member 50B.

[0126] In addition, in the present embodiment, the lower shell 320B of the second holding part 30B and the lower shell 420B of the second hair clamping part 40B are formed integrally. That is, the rotation connection part 110 side of the lower shell 220B becomes the lower shell 320B of the second holding part 30B. On the other hand, the top end side of the lower shell 220B becomes the lower shell 420B of the second hair clamping part 40B.

[0127] Furthermore, the cover 330B and the second hair holding member 50B are formed separately, and the upper case 230B is formed by attaching the cover 330B and the second hair holding member 50B so as to cover the opening portion of the lower case 220B.

[0128] Furthermore, in this embodiment, if Figure 6 As shown, the hollow portion S4 in the second housing 210B is partitioned into a hollow portion S5 on the second gripping portion 30B side and a hollow portion S6 on the second hair clamping portion 40B side by the partition wall 240B.

[0129] The partition wall 240B includes a wall portion 221B, a wall portion 331B, a seal 250B, and the like. The wall portion 221B is formed so as to protrude from the inner side (upper surface side) of the central portion of the lower shell 220B in the X direction (length direction: front-back direction) toward the upper side in the Z direction. The wall portion 331B is formed so as to protrude from the inner side (lower surface side) of the front side in the X direction of the cover 330B toward the lower side in the Z direction. The seal 250B is sandwiched between the wall portion 221B and the wall portion 331B. Thus, the partition wall 240B is formed.

[0130] Here, in the present embodiment, the portion of the second arm 20B that is further rearward than the partition wall 240B is set as the second gripping portion 30B, and the portion of the second arm 20B that is further forward than the partition wall 240B is set as the second hair clamping portion 40B. That is, in the hair iron 10 of the present embodiment, the portion on the top side (forward than the wall portion 331B) of the cover 330B also constitutes a part of the second hair clamping portion side housing 410B.

[0131] Moreover, in Figure 6 Various electrical components are housed in the hollow portion S5 on the second gripping portion 30B side and the hollow portion S6 on the second hair clamping portion 40B side.

[0132] Specifically, in this embodiment, electronic components (electrical components) such as the control device 340B for controlling the heater 530A and the heater 530B are housed in the hollow portion S5 on the second gripping portion 30B side. Electrical components such as the fuse 582B and the thermistor 583B are housed in the hollow portion S6 on the second hair clamping portion 40B side.

[0133] The above arrangement can enhance the waterproof effect of electronic components (electrical components) such as the control device 340B housed in the hollow portion S5 on the second gripping portion 30B side.

[0134] The heater 530A and the thermostat 582A are electrically connected to the control device 340B via the lead wire 581 that passes through the through hole formed in the seal 250A. In addition, the electrical components such as the fuse 582B and the thermistor 583B are electrically connected to the control device 340B via the lead wire 581.

[0135] In addition, in this embodiment, if Figure 3As shown in FIG. 1 , the top end 222B (the end on the front side in the X direction) of the lower shell 220B is bent toward the upper side (the second hair clamping surface 560B side). That is, by bending the top end 222B, it is easy for the user to hold the top end 222B when using the hair iron 10. In addition, a protrusion 222aB is formed on the top end 222B. The protrusion 222aB functions as an anti-slip member when the user holds the top end 222B. In addition, the protrusion 222aB also has the function of releasing the heat conducted from the heater 530B to the top end 222B (the gripping portion for the user to hold).

[0136] Furthermore, in this embodiment, if Fig. 9 As shown, there is a heat insulating member 430B arranged on the inner surface 420bB of the lower shell 420B. The heat insulating member 430B suppresses heat conduction from the heater 530B to the lower shell 420B. In addition, the heat insulating member 430B is formed in a shape along the concave inner surface 420bB of the lower shell 420B. The heat insulating member 430B has a through hole 431B formed in a part.

[0137] On the other hand, a protrusion 421B that protrudes upward (protrudes toward the second hair holding member 50B) is formed at a portion corresponding to the through hole 431B.

[0138] The heat insulating member 430B is disposed on the inner surface 420bB of the lower shell 420B in a state where the protrusion 421B penetrates the through hole 431B. Thus, the heat insulating member 430B is disposed in a state where it is positioned relative to the lower shell 420B.

[0139] That is, the heat insulating member 430B is disposed on the inner surface 420bB of the lower case 420B. Thus, even when the thickness of the second hair holding part 40B is reduced, heat transfer from the heater 530B to the lower case 420B can be suppressed.

[0140] In addition, if Fig. 9 As shown, the second hair holding member 50B constituting a part of the upper shell 230B includes a plate member 510B. The plate member 510B is also formed of a material having high thermal conductivity, such as copper or aluminum.

[0141] In addition, the second hair clamping member 50B includes a holding member 520B and a heater 530B, etc. The holding member 520B is supported by the lower shell 420B of the second hair clamping part 40B, and holds the plate member 510B. The heater 530B is thermally coupled to the plate member 510B, and conducts the generated heat to the plate member 510B.

[0142] The plate member 510B includes a plate portion 540B that is substantially plate-shaped (including plate-shaped). The plate portion 540B has a substantially flat (including flat) second hair clamping surface 560B formed on its surface (upper surface). In the present embodiment, the second hair clamping surface 560B is formed in a substantially rectangular shape (including rectangular shape) that is elongated in the longitudinal direction of the second housing 210B when viewed from above (when viewed from the bottom).

[0143] And, if Fig. 9 As shown, both ends of the plate portion 540B in the Y direction (width direction: the same direction as the width direction of the second hair clamping portion 40B) are formed to be curved toward the inside of the second housing 210B. In addition, the second hair clamping surface 560B has curved surfaces 562B at both ends in the Y direction (width direction), and the curved surfaces 562B are formed to be convex toward the oblique outside when viewed from a width direction section (a surface obtained by cutting with a vertical plane along the width direction).

[0144] That is, the second hair holding surface 560B is composed of a flat surface 561B (flat portion) in the center in the width direction and curved surfaces 562B formed at both ends in the width direction of the flat surface 561B.

[0145] Furthermore, the plate member 510B has a pair of legs 550B continuously arranged inwardly (downwardly) on the back side (downward side) of the plate portion 540B. The pair of legs 550B is held by the holding member 520B. Thus, the plate member 510B is held by the holding member 520B. Furthermore, the heater 530B is accommodated in the storage portion 570B formed between the pair of legs 550B. At this time, the heater 530B accommodated in the storage portion 570B is arranged in a manner of abutting against the inner surface of the plate portion 540B.

[0146] And, if Figure 6 As shown, electrical components such as a fuse 582B and a thermistor 583B are stored on the back side (lower side) of the heater 530B in the storage portion 570B.

[0147] As the heater 530B, for example, a PTC heater (Positive Temperature Coefficient heater) can be used. By using a PTC heater, continuous temperature control can be performed. However, as a heating device, it is not necessary to use a PTC heater, and for example, a nichrome wire heater or other heating devices can also be used.

[0148] In addition, a configuration may be adopted in which the heater (heat generating portion) is provided only in one of the first hair holding part 40A and the second hair holding part 40B.

[0149] In addition, as described above, in the present embodiment, the control device 340B for controlling the heater 530A and the heater 530B is housed in the hollow portion S5 on the second gripping portion 30B side. Furthermore, the temperature of the first hair clamping surface 560A and the temperature of the second hair clamping surface 560B can be set in stages by the control of the control device 340B.

[0150] Specifically, the thermostat 582A is mounted on the back side of the plate portion 540A and is electrically connected to the control device 340B. Then, the control device 340B controls the temperature of the heater 530A using the thermostat 582A.

[0151] On the other hand, thermistor 583B is mounted on the back of plate portion 540B and is electrically connected to control device 340B. Control device 340B controls the temperature of heater 530B using the resistance value of thermistor 583B, specifically, the resistance value of thermistor 583B that changes as the temperature of heater 530B changes.

[0152] In addition, in the present embodiment, the fuse 582B is provided on the back side of the plate portion 540B. Thus, when the temperature of the first hair clamping surface 560A and the temperature of the second hair clamping surface 560B exceed the predetermined temperature due to damage of the control device 340B, the fuse 582B is melted. Thus, the power supply to the heater (heater 530A, heater 530B) is blocked, and the occurrence of an undesirable situation can be prevented before it occurs. In addition, it is more preferable that the above-mentioned fuse is also provided on the back side of the plate portion 540A. Thus, the occurrence of an undesirable situation can be prevented more reliably.

[0153] In addition, if Fig. 9 As shown, the holding member 520B has a shape that is open upward, and is formed in a substantially mountain shape (including a mountain shape) that protrudes downward when viewed in cross section in the width direction.

[0154] In detail, the retaining member 520B includes a bottom wall portion 521B, a side wall portion 522B, a lower flat portion 521aB, an inclined portion 521bB, an upper flat portion 521cB and a side wall portion 522B. The side wall portion 522B is extended upward at both ends of the bottom wall portion 521B in the Y direction. The lower flat portion 521aB is located in the central portion of the Y direction (width direction) and is arranged at the position of the lower side of the bottom wall portion 521B. The inclined portion 521bB is respectively continuously provided at both ends of the lower flat portion 521aB of the bottom wall portion 521B in the Y direction (width direction), and extends outwardly and upwardly in the Y direction. In addition, the upper flat portion 521cB is respectively continuously provided at both ends of the inclined portion 521bB of the bottom wall portion 521B, and extends horizontally toward the outer side in the Y direction. Furthermore, as described above, the side wall portion 522B is provided continuously with both ends in the Y direction of the upper flat portion 521 cB of the bottom wall portion 521B.

[0155] In addition, it is preferable that at least one of the first hair clamping part 40A and the second hair clamping part 40B is supported to be relatively reciprocatingly movable in the up-down direction (normal direction) relative to the upper shell 420A of the first hair clamping part 40A and the lower shell 420B of the second hair clamping part 40B. According to this structure, it is possible to suppress excessive load from being applied to the hair clamped between the first hair clamping surface 560A and the second hair clamping surface 560B. As a result, it is possible to suppress damage to the hair.

[0156] Therefore, in this embodiment, the second hair clamping part 40B includes a second floating mechanism 60B. The second floating mechanism 60B holds the second hair clamping member 50B in a floating manner on the lower shell 420B (see Fig. 9 and Fig.10 ).

[0157] The second floating mechanism 60B includes two elastically deformable floating rubbers 610B (floating parts). The floating rubbers 610B are arranged at the center of the Y direction (width direction) in a state separated in the X direction (front-back direction). Moreover, the second hair clamping member 50B is relatively moved (floated) relative to the lower shell 420B by the elastic deformation of the two floating rubbers 610B.

[0158] The floating rubber 610B of this embodiment is formed in an arrow shape when viewed in cross section in the width direction, and has a neck 611B on the root side and an arrow portion 612B on the top side. The arrow portion 612B has a shape that decreases in diameter as it goes toward the top side, and has a flat surface 612aB with a larger area on the root side. On the other hand, the top of the arrow portion 612B has a flat surface 612bB with a smaller area than the flat surface 612aB. In addition, the neck 611B is provided continuously with the center of the flat surface 612aB.

[0159] The neck 611B on the root side of the floating rubber 610B passes through the through hole 621B formed in the lower flat portion 521aB of the bottom wall portion 521B. Thus, the floating rubber 610B is held by the bottom wall portion 521B of the retaining member 520B. At this time, the flat surface 612aB on the root side (neck 611B side) of the arrow portion 612B is accommodated in the space 623B surrounded by the rib 622B formed in the lower flat portion 521aB of the bottom wall portion 521B.

[0160] On the other hand, the flat surface 612bB on the tip side (reduced diameter portion) of the arrow portion 612B is accommodated in a space 632B surrounded by a peripheral wall 631B formed at the lower portion of the protrusion 421B of the lower shell 420B.

[0161] According to the above structure, in the present embodiment, the second hair clamping member 50B is supported on the lower shell 420B by means of the elastically deformable floating rubber 610B. In other words, the second hair clamping member 50B is held on the lower shell 420B in a floating manner. Thus, the second hair clamping surface 560B can swing along the normal direction (Z direction: up and down direction) of the second hair clamping surface 560B.

[0162] In addition, the swing of the second hair holding surface 560B along the normal direction of the second hair holding surface 560B includes the situation that the second hair holding surface 560B moves parallel to the normal direction of the second hair holding surface 560B. In addition, the above-mentioned swing also includes the situation that one end of the second hair holding surface 560B moves relative to the other end of the second hair holding surface 560B along the normal direction of the second hair holding surface 560B.

[0163] That is, in the present embodiment, the swinging of the second hair holding surface 560B along the normal direction of the second hair holding surface 560B means the movement of the second hair holding surface 560B parallel to the normal direction of the second hair holding surface 560B, and the rotation of the second hair holding surface 560B around the axis along the XY plane.

[0164] And, if Fig.11 and Fig.12 As shown, the second hair holding part 40B of this embodiment includes a second rotation mechanism 70B. The second rotation mechanism 70B is configured to rotate the second hair holding surface 560B (second hair holding member 50B) around a second rotation axis 710B extending in the X direction (front-rear direction).

[0165] Specifically, the second rotation mechanism 70B includes a second rotation piece 720B and a support portion 730B that slidably supports the second rotation piece 720B.

[0166] The second rotating piece 720B is formed on both sides of the holding member 520B in the X direction in a manner protruding outward in the X direction. The second rotating piece 720B has a shape that is curved in a manner protruding downward (in the Z direction). In addition, the concave surface 721B formed on the upper side (the second hair clamping surface 560B side) of the second rotating piece 720B is supported on the supporting portion 730B in a slidable manner.

[0167] That is, the concave curved surface 721B is formed as an arc centered on the second rotation axis 710B when viewed in cross section in the width direction (Y direction).

[0168] Here, in the present embodiment, a second groove portion 711B extending along the X direction (front-back direction: length direction) is formed in the Y direction (width direction) center portion of the second hair holding surface 560B (see Fig.13 ). In addition, the depth of the second groove portion 711B is also formed, for example, at about 1 mm. Moreover, the second groove portion 711B corresponds to the second rotation axis 710B described above. Therefore, in the present embodiment, the concave curved surface 721B is formed as an arc centered on the second groove portion 711B when viewed from a cross-section in the width direction. In the present embodiment, the second groove portion 711B is formed in such a manner that the second groove portion 711B is opposite to the first groove portion 711A in the Z direction (thickness direction) when the first arm portion 20A and the second arm portion 20B are closed.

[0169] The support portion 730B of the second rotating mechanism 70B includes two outer ribs 731B and two inner ribs 732B. The outer ribs 731B are provided at the outer side in the Y direction (width direction). The inner ribs 732B are provided at the inner side in the Y direction (width direction) of the two outer ribs 731B.

[0170] The outer rib 731B and the inner rib 732B are respectively Figure 6 The inner surface of the hollow portion S6 on the second hair holding portion 40B side of the upper shell 230B shown in the figure is formed so as to protrude toward the lower shell 420B.

[0171] In addition, in the present embodiment, the outer rib 731B and the inner rib 732B on one side (the rear side in the front-to-back direction) are formed on the cover 330B serving as the upper shell 230B. Furthermore, the outer rib 731B and the inner rib 732B on the other side (the front side in the front-to-back direction) are formed on the portion of the upper shell 230B covering the opening of the lower shell 220B on the front side relative to the second hair clamping member 50B.

[0172] Furthermore, in the present embodiment, the protrusion amount of the two inner ribs 732B is smaller than the protrusion amount of the two outer ribs 731B.

[0173] Furthermore, the concave surface 721B of the second rotating piece 720B is brought into sliding contact with the top ends of the two inner ribs 732B. Thus, the second rotating piece 720B is supported on the supporting portion 730B in a slidable manner. At this time, the two outer ribs 731B are configured to suppress the misalignment of the second rotating piece 720B along the Y direction (width direction). Thus, when the second hair clamping surface 560B (second hair clamping member 50B) is relatively rotated relative to the lower shell 220B, the sliding contact between the concave surface 721B of the second rotating piece 720B and the top ends of the two inner ribs 732B is not released.

[0174] As described above, in this embodiment, the second rotating piece 720B is rotatably supported by the supporting portion 730B. Thus, the second hair holding surface 560B can rotate around the second groove portion 711B (second rotating shaft 710B) extending in the X direction (front-back direction).

[0175] In addition, in the present embodiment, an example in which the second rotation axis 710B is an invisible axis has been described, but it may be a visible axis.

[0176] In addition, in the present embodiment, a predetermined interval d is formed between the first hair holding surface 560A and the second hair holding surface 560B when the first arm 20A and the second arm 20B are closed. The predetermined interval d is equivalent to the space formed between the first hair holding surface 560A and the second hair holding surface 560B.

[0177] The second arm portion 20B is configured as described above.

[0178] In addition, in the hair iron 10 of the present embodiment, as described above, the discharge device 80 is disposed in the hollow portion S3 on the first hair clamping portion 40A side (see Figure 6 ).

[0179] The discharge device 80 generates ions and supplies the generated ions to the hair, thereby further improving the hair care effect.

[0180] Furthermore, the hair iron 10 of the present embodiment can achieve miniaturization in the Z direction (thickness direction) of the hair iron 10 by providing the discharge device 80 at the above-mentioned position.

[0181] Specifically, the discharge device 80 is arranged at a portion in the hollow portion S3 in the first hair holding portion 40A that does not overlap with the first hair holding surface 560A. That is, in the present embodiment, the discharge device 80 is arranged in a state where the discharge device 80 and the first hair holding surface 560A do not overlap when viewed along the normal direction (Z direction: thickness direction) of the first hair holding surface 560A. By arranging the discharge device 80 as described above, it is configured so that the normal line of the first hair holding surface 560A and the discharge device 80 do not intersect.

[0182] Furthermore, in the present embodiment, the discharge device 80 is arranged near the approximate center (including the center) of the short side (the short side on the rear side) of the adjacent first hair holding surface 560A.

[0183] Specifically, the partition wall 240A is arranged at the rear of the X direction (front-back direction), and the partition wall 240A divides the hollow portion S1 in the first housing 210A into a hollow portion S2 on the first holding portion 30A side and a hollow portion S3 on the first hair clamping portion 40A side. In addition, in the present embodiment, the partition wall 240A is arranged in a manner that is located at a position that is rearward of the X direction (front-back direction) than the partition wall 240B. Thus, the length (length in the X direction) of the first hair clamping portion 40A formed at a position that is forward of the partition wall 240A is longer. As a result, a relatively large space can be formed between the partition wall 240A and the first hair clamping surface 560A (first hair clamping member 50A).

[0184] The discharge device 80 is disposed in a space formed between the partition wall 240A and the first hair holding surface 560A (first hair holding member 50A). In other words, the discharge device 80 is disposed close to the short side (the short side on the rear side) of the first hair holding surface 560A.

[0185] In the present embodiment, the discharge device 80 is arranged at the center of the space formed between the partition wall 240A and the first hair holding surface 560A in the Y direction (width direction). Thus, the discharge device 80 is arranged near the approximate center (including the center) of the short side (the short side on the rear side) of the first hair holding surface 560A to which it is adjacent.

[0186] In addition, in this embodiment, if Fig.15 As shown, the discharge device 80 is exemplified as a structure including, for example, a first electrode 810 and a second electrode 820 (counter electrode: an electrode that forms a pair with the first electrode 810). The second electrode 820 is arranged separately from the first electrode 810, and discharge is performed between the second electrode 820 and the first electrode 810 (see Fig.15 ). The first electrode 810 and the second electrode 820 are formed of, for example, a transition metal such as stainless steel or titanium.

[0187] The discharge device 80 includes a moisture-proof cover 830 that holds the first electrode 810 and the second electrode 820. The moisture-proof cover 830 is formed in a substantially box shape (including a box shape) that is open upward, and the first electrode 810 and the second electrode 820 are held in a hollow portion of the moisture-proof cover 830 in an exposed state.

[0188] The first electrode 810 and the second electrode 820 of the discharge device 80 of this embodiment are connected by Figure 6 The wire 581 shown is electrically connected to the control device 340A. Then, a high voltage is applied between the first electrode 810 and the second electrode 820. Thus, the discharge device 80 is configured to be able to generate discharge (corona discharge, etc.).

[0189] In addition, as the discharge device 80, for example, a charged particle generating device that generates a charged particle liquid (for example, mist or the like) or a metal particle generating device that generates metal particles can be used.

[0190] Furthermore, the ions (charged particle liquid such as mist, metal particles) generated in the above-mentioned discharge device 80 (charged particle generating device, metal particle generating device) are emitted toward the hair from the ion emission port 333A. Thus, the ions generated in the discharge device 80 are supplied to the hair via the ion emission port 333A. Therefore, the hair care effect can be further improved by the supplied ions.

[0191] In this embodiment, if Fig.13 and Fig.14 As shown, an ion emission port 333A is formed in the front portion of the cover 330A which covers the space formed between the partition wall 240A and the first hair holding surface 560A.

[0192] Specifically, the cover 330A is formed in a manner that its front end portion faces upward (toward the upper shell 220A side) and is inclined. In addition, the cover 330A is provided with an opening 334A having a substantially rectangular shape (including a rectangular shape) formed at the inclined portion of the front end. The opening 334A is connected to the hollow portion S3 ( Fig.15 The opening 334A is divided into three openings of a substantially rectangular shape (including a rectangular shape) by two partition walls 335A arranged separately in the Y direction (width direction). Among the divided openings, the openings formed on both sides of the Y direction (width direction) serve as ion emission ports 333A.

[0193] That is, in the present embodiment, the ion emission port 333A is arranged on the surface of the first hair holding part 40A facing the second hair holding part 40B and is arranged close to the rotation coupling part 110 side of the first hair holding surface 560A.

[0194] The two ion emission ports 333A are formed to communicate with the discharge device 80 (the hollow portion in the moisture-proof cover 830). That is, the first electrode 810 and the second electrode 820 of the discharge device 80 are arranged to face the ion emission ports 333A.

[0195] Furthermore, in this embodiment, the ion emission port 333A faces Fig. 9 The hair holding surface 560A and the hair holding surface 560B are formed to have a predetermined interval d (a space formed between the first hair holding surface 560A and the second hair holding surface 560B).

[0196] Thus, ions (negative ions, positive ions) and charged particle liquid generated in the discharge device 80 are discharged from the ion discharge port 333A to the space (predetermined interval d) formed between the first hair holding surface 560A and the second hair holding surface 560B.

[0197] That is, the ion emission port 333A is formed so as to be able to supply ions (negative ions, positive ions) and charged particle liquid generated in the discharge device 80 to the hair clamped by the first hair clamping surface 560A and the second hair clamping surface 560B.

[0198] In the present embodiment, the opening formed in the center of the three openings in the Y direction (width direction) constitutes a liquid suction port 332A, which introduces the liquid from the hair into the hollow portion in the substantially box-shaped (including box-shaped) moisture-proof cover 830 (see Fig.13 and Fig.14 ).

[0199] Therefore, in the present embodiment, the ion emission ports 333A are respectively arranged near both end portions of the short sides of the adjacent first hair holding surface 560A with the liquid suction port 332A interposed therebetween.

[0200] That is, the liquid suction port 332A of the present embodiment is arranged on the surface of the first hair clamping part 40A that is opposite to the second hair clamping part 40B and is arranged close to the rotation connection part 110 side of the first hair clamping surface 560A. In addition, the liquid suction port 332A is arranged near the approximate center (including the center) of the short side of the first hair clamping surface 560A to which it is close.

[0201] As described above, the liquid suction port 332A is formed to communicate with the discharge device 80 (hollow portion in the moisture-proof cover 830). The liquid suction port 332A and the first groove portion 711A (groove) are arranged on substantially the same axis (first rotation axis 710A).

[0202] Thus, the moisture from the hair sandwiched between the first hair holding surface 560A and the second hair holding surface 560B can be easily supplied to the discharge device 80 via the first groove portion 711A.

[0203] That is, the liquid suction port 332A is formed to introduce liquid such as water held by the hair sandwiched between the first hair holding surface 560A and the second hair holding surface 560B into the discharge device 80. In addition, as the liquid, for example, hair conditioning agents can be exemplified in addition to water.

[0204] And, if Figure 8 As shown, the liquid suction port 332A of the present embodiment is arranged so as to also face the second groove portion 711B.

[0205] According to the above configuration, water from the hair sandwiched between the first hair holding surface 560A and the second hair holding surface 560B is supplied from the first groove portion 711A and the second groove portion 711B to the discharge device 80 via the liquid suction port 332A.

[0206] That is, in the present embodiment, the first groove portion 711A and the second groove portion 711B constitute a liquid passage for supplying liquid such as water to the discharge device 80 .

[0207] As described above, the liquid suction port 332A is formed to introduce liquid such as water held by the hair sandwiched between the first hair holding surface 560A and the second hair holding surface 560B into the discharge device 80 .

[0208] On the other hand, the ion emission port 333A is formed to supply ions (negative ions, positive ions) and charged particle liquid generated by discharge between the first electrode 810 and the second electrode 820 to the hair clamped by the first hair clamping surface 560A and the second hair clamping surface 560B.

[0209] Thus, when the hair iron 10 is used, liquid from the hair clamped by the first hair clamping surface 560A and the second hair clamping surface 560B is introduced from the liquid passage (the first groove 711A and the second groove 711B) through the liquid suction port 332A into the discharge device 80. Then, the gas such as water vapor introduced into the discharge device 80 contacts the first electrode 810 and the second electrode 820 to form condensation.

[0210] Furthermore, the liquid passage described above can also be applied to a discharge device having a structure that performs discharge without causing condensation of liquid such as water and generates only ions.

[0211] Furthermore, when discharge occurs in the discharge device, a negative voltage may be applied between the electrodes to generate negative ions, and a positive voltage may be applied between the electrodes to generate positive ions.

[0212] In addition, a structure in which negative voltage and positive voltage are applied alternately when discharge occurs in the discharge device may be used to alternately generate negative ions and positive ions. Furthermore, the structure may be formed by a discharge device having a plurality of electrodes. In this case, a structure in which a negative voltage is applied to any electrode among the plurality of electrodes and a positive voltage is applied to any electrode among the other electrodes may be used to simultaneously generate negative ions and positive ions.

[0213] The discharge device 80 described in the present embodiment is merely an example, and various discharge devices may be arranged in a portion that does not overlap with the first hair holding surface 560A.

[0214] Hereinafter, an example of the operation and effect of the hair iron 10 configured as described above will be described.

[0215] First, user operation (open) Figure 8 The operation switch 150 provided in the hair iron 10 is shown to energize the heaters (heaters 530A and 530B). As a result, the heaters (heaters 530A and 530B) generate heat, and the heat is transferred from the heated heaters (heaters 530A and 530B) to the plate portions 540A and 540B. As a result, the plate portions 540A and 540B are heated.

[0216] At this time, the control device 340A controls the temperature of the first hair clamping surface 560A and the temperature of the second hair clamping surface 560B to be heated to a predetermined temperature (e.g., 170° C.). Figure 8 The display unit 160 formed by the second arm portion 20B shown in the figure is displayed. Thus, the user is informed that the temperature of the first hair holding surface 560A and the temperature of the second hair holding surface 560B have reached a predetermined temperature. In addition, the display unit 160 is composed of, for example, an LED, a light guide member, etc.

[0217] Next, in a state where the first hair holding surface 560A and the second hair holding surface 560B are heated to a predetermined temperature, the user clamps the hair between the first hair holding surface 560A and the second hair holding surface 560B.

[0218] At this time, the first hair holding surface 560A can be subjected to floating deformation and a rotational motion based on the first rotation axis 710A.

[0219] Likewise, the second hair holding surface 560B can be subjected to floating deformation and a rotational motion based on the second rotation axis 710B.

[0220] Thereby, the hair of the user can be appropriately heated by the first hair holding surface 560A and the second hair holding surface 560B.

[0221] At this time, when the user wants to give a curly shape, the user rotates the hair iron 10, for example, more than half a turn, while the hair is clamped between the first hair clamping surface 560A and the second hair clamping surface 560B. As a result, the hair at the part not clamped by the first hair clamping surface 560A and the second hair clamping surface 560B is spirally wound on the outer surface (outer surface 420aA, outer surface 420aB).

[0222] Then, the user slides the hair iron 10 along the hair and pulls it down toward the hair tip while pressing the hair against the outer surface (outer surface 420aA, outer surface 420aB), thereby giving the hair a curly shape.

[0223] On the other hand, when the user wants to give a straight shape, the user does not rotate the hair iron 10 but slides along the hair and pulls it down toward the hair tip while holding the hair. Thus, a straight shape is given to the hair.

[0224] When the hair iron 10 is used, if a high voltage is applied between the first electrode 810 and the second electrode 820 of the discharge device 80, discharge (corona discharge, etc.) will occur. As a result, ions (negative ions, positive ions) and charged particle liquid are generated. Then, the generated ions (negative ions, positive ions) and charged particle liquid are passed through Fig.13 The ion emission port 333A is shown to emit ions toward the hair.

[0225] Furthermore, when the hair iron 10 is used, as the hair is heated, moisture from the user's hair evaporates, generates water vapor, and expands. Then, due to the generation and expansion of water vapor, moisture from the user's hair reaches the liquid suction port 332A via the liquid passage (the first groove 711A and the second groove 711B).

[0226] In addition, in the present embodiment, the first groove 711A and the liquid suction port 332A are arranged on substantially the same axis (including the same axis). Therefore, even when the first hair clamping surface 560A is rotated, the positional relationship between the first groove 711A and the liquid suction port 332A remains almost unchanged.

[0227] Furthermore, when the first arm 20A and the second arm 20B are closed, the second groove 711B is also arranged on substantially the same axis (including the same axis) as the liquid suction port 332A. Therefore, when the hair is clamped between the first hair clamping surface 560A and the second hair clamping surface 560B, the positional relationship between the second groove 711B and the liquid suction port 332A remains almost unchanged even if the second hair clamping surface 560B rotates.

[0228] According to the above configuration, the moisture in the liquid passage (the first groove portion 711A and the second groove portion 711B) can be more efficiently allowed to reach the liquid suction port 332A.

[0229] Then, by applying a voltage to the discharge device 80, the water derived from the hair and reaching the liquid suction port 332A is converted into plasma.

[0230] Then, the ions generated in the discharge device 80 are discharged forward from the ion discharge port 333A, and are supplied to the hair clamped by the first hair clamping surface 560A and the second hair clamping surface 560B.

[0231] That is, by applying a high voltage between the first electrode 810 and the second electrode 820 of the discharge device 80, the generated ions (negative ions, positive ions) and charged particle liquid are supplied to the hair, thereby giving the user's hair a curly or straight shape.

[0232] At this time, if a charged particle generating device that generates mist is provided as the discharge device 80, the condensed water is atomized by a discharge action such as corona discharge. Thus, very small mist of nanometer size (negatively charged mist containing negative ions) is generated, and the generated mist is supplied to the hair. Thus, the hair can be moisturized.

[0233] If a metal particle generator is provided as the discharge device 80, metal particles (metal molecules, ions, etc.) are discharged from the first electrode 810, the second electrode 820, etc. by a discharge action such as corona discharge, and the discharged metal particles are supplied to the hair.

[0234] In addition, the first electrode and the second electrode of the metal particle generating device can be composed of a transition metal (such as gold, silver, copper, platinum, zinc, titanium, rhodium, palladium, iridium, ruthenium, osmium, etc.) single body, alloy, or a component obtained by plating the transition metal.

[0235] Furthermore, when the metal particles generated and discharged by the discharge portion of the metal particle generating device contain gold, silver, copper, zinc, etc., the contained metal particles can be used to produce an antibacterial effect. In addition, when the metal particles contain platinum, zinc, titanium, etc., the contained metal particles can be used to produce an antioxidant effect.

[0236] In addition, it is known that platinum particles have an extremely high anti-oxidation effect. In addition, the portion of the metal particle generator that does not emit metal particles (for example, an electrode that functions as a ground electrode) can be made of, for example, stainless steel, tungsten, or the like.

[0237] Alternatively, the discharge portion of the metal particle generating device may generate ions (e.g., negative ions, such as NO2) by discharge. － 、NO3 － The ions generated collide with the first electrode, the second electrode, other components containing metal materials and metal components, etc., thereby generating metal particles. Specifically, the second electrode and the other components are composed of materials containing the above-mentioned transition metal. Moreover, the structure in which metal particles are released from the material containing the transition metal can also be used.

[0238] According to the above-mentioned structure, when the hair is treated using the hair iron 10, damage to the hair due to the treatment can be effectively suppressed.

[0239] As described above, the hair iron 10 of this embodiment includes: a first hair clamping portion 40A having a first hair clamping surface 560A; and a second hair clamping portion 40B having a second hair clamping surface 560B that can be opposite to the first hair clamping surface 560A. In addition, the hair iron 10 clamps hair in a state where the first hair clamping surface 560A and the second hair clamping surface 560B are opposite to each other.

[0240] The hair iron 10 of this embodiment includes a discharge device 80 for generating ions and an ion discharge port 333A for discharging ions generated in the discharge device 80. The discharge device 80 is disposed in a portion of the first hair holding portion 40A that does not overlap with the first hair holding surface 560A.

[0241] That is, by providing the discharge device 80 in the hair iron 10, the hair care effect can be further improved.

[0242] Furthermore, the discharge device 80 is disposed in a portion that does not overlap with the first hair holding surface 560A in the first hair holding portion 40A. Thus, the thickness of the first hair holding portion 40A can be further reduced. As a result, the height (thickness) of the hair iron 10 can be suppressed to be small.

[0243] According to the structure of the hair iron 10 of the present embodiment described above, it is possible to achieve miniaturization in the thickness direction while improving the hair care effect.

[0244] Furthermore, by achieving miniaturization in the thickness direction, the hair iron 10 can be moved to a position closer to the hair root side when the hair iron 10 is used. Furthermore, the hair closer to the hair root side can also be clamped by the hair iron 10. As a result, the hairdressing performance of the hair iron 10 can be further improved.

[0245] However, if the discharge device 80 is disposed in the portion overlapping with the first hair holding surface 560A in the first hair holding portion 40A, when the first hair holding surface 560A is supported to be rotatable and floating, there is a possibility that the discharge device 80 may interfere. Therefore, there is a possibility that the structure in which the first hair holding surface 560A is supported to be rotatable and floating cannot be adopted.

[0246] Therefore, in the hair iron 10 of the present embodiment, the discharge device 80 is arranged in the first hair clamping portion 40A at a portion that does not overlap with the first hair clamping surface 560A. Thus, it is possible to adopt a structure in which the discharge device 80 does not exist within the rotation range and floating support range of the first hair clamping surface 560A. Therefore, it is possible to more reliably adopt a structure in which the first hair clamping surface 560A is supported to be rotatable and floating.

[0247] Furthermore, the ion emission port 333A may be disposed in the first hair holding portion 40A in a state facing a space (predetermined interval d) formed between the first hair holding surface 560A and the second hair holding surface 560B.

[0248] That is, the ion emission port 333A is arranged in the first hair holding portion 40A at a portion facing the space sandwiched between the first hair holding surface 560A and the second hair holding surface 560B. Thus, a sufficient amount of ions can be supplied to the hair.

[0249] Furthermore, the hair iron 10 of the present embodiment may be configured such that a first groove portion (groove) 711A extending along the longitudinal direction of the first hair holding surface 560A is formed on the first hair holding surface 560A.

[0250] Thus, the first groove portion (groove) 711A can function as a liquid passage for supplying liquid such as water originating from the hair sandwiched between the first hair holding surface 560A and the second hair holding surface 560B to the discharge device 80. As a result, liquid such as water originating from the hair sandwiched between the first hair holding surface 560A and the second hair holding surface 560B can be easily supplied to the discharge device 80. As a result, stable generation of ion components can be promoted.

[0251] Furthermore, the hair iron 10 of the present embodiment may be configured to include a liquid suction port 332A connected to the discharge device 80, and the first groove portion (groove) 711A and the liquid suction port 332A may be arranged substantially on the same axis.

[0252] Thus, the hair iron 10 has the liquid inlet 332A connected to the discharge device 80, and the first groove 711A and the liquid inlet 332A are arranged on substantially the same axis (including the same axis). As a result, liquid such as water from the hair can be supplied to the discharge device 80 more efficiently.

[0253] Furthermore, the hair iron 10 of the present embodiment may be configured such that the first hair holding surface 560A is rotatable about the first rotation axis 710A, and the first groove portion (groove) 711A is configured as the first rotation axis 710A.

[0254] Thus, the first hair holding surface 560A can be rotated while minimizing the position change of the first groove portion (groove) 711A. As a result, regardless of the rotation state of the first hair holding surface 560A, liquid such as water derived from the hair can be more efficiently supplied to the discharge device 80.

[0255] Furthermore, the hair iron 10 of the present embodiment may be configured such that the first hair clamping portion 40A is provided with a floating rubber 610A (floating portion) that causes the first hair clamping surface 560A to swing in the normal direction of the first hair clamping surface 560A.

[0256] Thus, the contact between the first hair clamping surface 560A and the hair can be more reliably ensured. As a result, the heating efficiency of the hair can be further improved. In addition, the adhesion of the first hair clamping surface 560A to the hair can be further improved. Therefore, when the hair is shaped in a straight shape, the straightness of the hair can be further improved.

[0257] Furthermore, the hair iron 10 of the present embodiment may be configured such that the second hair clamping portion 40B is provided with a floating rubber 610B (floating portion) which causes the second hair clamping surface 560B to swing along the normal direction of the second hair clamping surface 560B.

[0258] Thus, the contact between the second hair clamping surface 560B and the hair can be more reliably ensured. Therefore, the heating efficiency of the hair can be further improved. In addition, the fit of the second hair clamping surface 560B to the hair can be further improved. Therefore, when the hair is shaped in a straight shape, the straightness of the hair can be further improved.

[0259] As mentioned above, although the preferred embodiment of this disclosure was described, this disclosure is not limited to the above-mentioned embodiment, and various modifications are possible.

[0260] For example, the present disclosure can also be applied to a hair iron in which the first hair holding surface and the second hair holding surface can come into contact with each other.

[0261] Furthermore, in the above-mentioned embodiment, the configuration in which the second electrode faces the first electrode is described as an example, but the present invention is not limited thereto. For example, the configuration in which the second electrode does not face the first electrode may be adopted.

[0262] In the above embodiment, the structure including the first electrode and the second electrode is described as an example, but the present invention is not limited thereto. For example, a structure may be adopted in which the second electrode is not provided and discharge is performed between the first electrode and a component member located near the first electrode.

[0263] In addition, in the above-mentioned embodiment, the structure in which the discharge unit is provided on the upper hair clamping part side, i.e., the first hair clamping part, is described as an example, but the invention is not limited thereto. For example, a discharge device may also be provided on the lower hair clamping part, i.e., the second hair clamping part. In addition, a structure in which the discharge device is provided only on the second hair clamping part may also be provided. In addition, in the case in which the discharge device is provided only on the lower hair clamping part, in the present embodiment, the lower hair clamping part is equivalent to the first hair clamping part, and the upper hair clamping part is equivalent to the second hair clamping part.

[0264] In addition, in the above-mentioned embodiment, the hair iron having a structure in which the first holding portion is provided separately from the first hair clamping portion is described as an example, but the invention is not limited thereto. For example, the hair iron may be provided with a structure in which a part of the first hair clamping portion functions as the holding portion, and a discharge device is arranged in the holding portion, which is a part of the first hair clamping portion.

[0265] Furthermore, in the above-described embodiment, it is needless to say that the specifications (shape, size, layout, etc.) of the corresponding holding portion, hair clamping portion, and other detailed portions can also be appropriately changed.
