DETAILED DESCRIPTION

[0022] The following is an explanation of the embodiments of the present invention using the drawings. Various features shown in the embodiments shown below can be combined with each other.

[0023] The following will refer to Figures 1 to 5 A hair curler according to an embodiment of the present disclosure is described below. Figure 1 It is a three-dimensional diagram showing a hair curling iron. Figure 2 It is a perspective view showing a state in which the front end side of the pressing plate is lifted.

[0024] Figure 3 and Figure 4 It is an exploded perspective view of a hair curling iron. Figure 5 This is a view of the hair curling unit from the tip side (+X direction in the figure) with the cap removed. Figure 5 In the figure, structures other than the perm section are omitted.

[0025] In the following description, a good thermal conductor is a material with high thermal conductivity, such as aluminum, copper, graphite sheet, aluminum nitride, etc. In addition, a so-called poor thermal conductor is a material with low thermal conductivity, such as polyethylene terephthalate, polycarbonate, ABS resin, etc.

[0026] like Figure 1 As shown, the hair iron 1 includes a handle 2, a hair ironing part 3, and a pressing part 4. The hair iron 1 also includes a cover 6 and a power supply part 7.

[0027] In a state where the hair iron section 3 is heated, for example, the hair iron 1 can curl the hair by winding the hair.

[0028] The cover 6 is disposed at the tip side (+X side in the figure) of the hair iron 1 and is formed by a poor conductor of heat. Thus, the user can grasp the handle 2 and the cover 6 at the same time, and thus can stably perform styling even if the user grasps the handle 2 with a weak force.

[0029] The handle portion 2 is configured to be grasped by a user. Figure 2 As shown, the handle portion 2 includes a handle body 21, an operating portion 22, and a foot portion 23. In addition, the handle portion 2 (handle body 21) has wiring or a substrate, etc., which are not shown in the figure, inside. The handle portion 2 is formed of a poor conductor of heat to prevent the heat from the curling portion 3 from being transferred to the user's hand or the wiring and substrate, etc., inside the handle body 2.

[0030] In order to facilitate the user's grip, the handle body 21 has a long strip shape, and is formed so that the tip side (+X side in the figure) is thicker than the base side (-X side in the figure). The surface of the handle body 21 can also be covered with a sheet having a buffer function and / or an anti-slip function. As a result, the user can grip the handle body 21 more stably.

[0031] The operation unit 22 includes a power button 221 and a temperature adjustment button 222 that are operated by the user. In addition, the operation unit 22 includes a display panel 223 that displays the temperature of the hair ironing unit 3.

[0032] The foot 23 is a convex portion formed on the side of the hair iron 1 opposite to the pressing portion 4 (-Y side in the figure). The foot 23 functions as a supporting mechanism together with the cover 6. When the hair iron 1 is placed on a table or the like with the pressing portion 4 as the upper side, the foot 23 and the cover 6 are in contact with the table or the like and can support the entirety of the hair iron 1. At this time, since the hair iron 3 can be prevented from contacting the table or the like, the hair iron 1 can be placed on the table or the like even when the hair iron 3 is heated. In addition, since the foot 23 is formed on the side opposite to the pressing portion 4, the pressing portion 4 is unlikely to become an obstacle when the hair iron 1 is placed on the table or the like.

[0033] Note that the part that constitutes the support mechanism together with the foot 23 may also be the part (base end) of the base end side (-X side in the figure) of the handle body 21 instead of the tip end side cover 6. In this case, if a counterweight is provided inside or outside the base end of the handle body 21, when the hair iron 1 is placed on a table or the like, the entirety of the hair iron 1 can be stably supported by the foot 23 and the base end of the handle body 21. At this time, the tip end side (+X side in the figure) of the hair iron 3 overcomes gravity and is lifted obliquely upward, so that the hair iron 3 can be prevented from contacting the table or the like.

[0034] A power supply unit 7 is mounted on the base end side (-X side in the figure) of the handle body 21. When the power supply unit 7 is connected to a power source (not shown), electric energy is supplied to the hair iron 1. The electric energy supplied by the power supply unit 7 is supplied to each part via wiring (not shown) inside the handle body 21.

[0035] The curling part 3 is provided at the tip side (+X side in the figure) of the handle part 2 and is used when curling the hair. Figure 5 As shown, the hair iron section 3 includes a hair iron body (main body) 31 , a pair of electrodes 32 , and a pair of heaters 38 .

[0036] The hair iron body 31 is formed in a cylindrical shape to be wound around the user's hair to curl it. Since the hair iron body 31 is formed of a good thermal conductor, the heat generated by the heater 38 can be well transferred to the hair wound around the hair iron body 31.

[0037] The pair of electrodes 32 are provided at relative positions on the circumferential surface of the hair iron body 31. Specifically, when the pressing portion 4 is set at the upper side (+Y side in the figure), the pair of electrodes 32 are provided at relative positions on the sides (+Z side and -Z side in the figure) of the hair iron body 31. In addition, the pair of electrodes 32 are exposed from the hair iron body 31. Therefore, the hair wound on the hair iron body 31 can be brought into contact with the electrodes 32 at the positions on the sides.

[0038] Since the exposed surface of each electrode 32 is formed into a curved surface, the curling shape of the hair wound around the hair iron body 31 is less likely to vary.

[0039] Each electrode 32 is in the shape of a strip and is arranged along the length direction (X direction in the figure) of the hair iron body 31. Therefore, even if the user has short hair, as long as the hair can be wrapped around half of the circumference of the hair iron body 31, the hair can be firmly in contact with the two electrodes 32.

[0040] The inner surface of each electrode 32 is in contact with a contact 321. A wiring 322 connected to a wiring (not shown) inside the handle body 21 is connected to each contact 321. Charge (current) flows into or out of each electrode 32 via the contact 321 and the wiring 322.

[0041] Each electrode 32 has the function of introducing or extracting ions into the hair. Specifically, when the hair is wound around the hair iron body 31, that is, when the hair contacts each electrode 32, when a pulse waveform current flows, ions are introduced into the hair from the electrode 32. Thus, the beauty ingredients contained in the hair care etc. can be ionized and fully penetrated into the hair. In addition, the electrode also has the function of adsorbing charged dirt on the hair.

[0042] An electrode holder 33 is disposed between each electrode 32 and the hair iron body 31. The electrode holder 33 is formed of a poor thermal conductor and can prevent the electrode 32 from being excessively heated by heat transfer from the hair iron body 31.

[0043] Each electrode 32 is inserted from the tip side (+X side in the figure) or the base side (-X side in the figure) into an electrode holder 33 fixed to the hair iron body 31 by screws (not shown), so as to be fixed in the up-down direction (Y direction in the figure) and the left-right direction (Z direction in the figure). In addition, a cover 6 is fixed to the tip side (+X side in the figure) of each electrode 32, and a handle 2 is fixed to the base side (-X side in the figure), which are respectively fixed to the hair iron body 31. Thus, each electrode 32 is prevented from falling off from the hair iron body 31 in each direction.

[0044] The pair of heaters 38 generate heat by electric energy supplied through the power supply unit 7. The pair of heaters 38 are disposed at the inner side of the hair iron body 31 and are disposed opposite to each other at a position further inward than the pair of electrodes 32. According to such an arrangement, compared with the case where the heaters 38 are disposed at the inner side of the hair iron body 31, that is, at the pressing portion 4 side (upper side, +Y side in the figure), the hair sandwiched between the hair iron body 31 and the pressing plate 41 (pressing portion 4) is prevented from being excessively heated. That is, damage to the hair due to heat or loss of moisture can be suppressed.

[0045] Each heater 38 is in the shape of a strip and is arranged along the length direction (Y direction in the figure) of the hair iron body (main body) 31. A heater pressing member 381 is arranged inside each heater 38 to prevent the heater 38 from leaving the hair iron body 31. By arranging two heaters 38 in this way, it is easy to quickly and evenly transfer heat to the entire hair iron body 31. Therefore, the inconvenience of the user caused by the long waiting time can be reduced, and the desired styling can be achieved.

[0046] Each heater 38 includes a heat generating element (not shown) and an insulator covering the heat generating element.

[0047] The insulator of each heater 38 is preferably composed of alumina as a main component. In this case, each heater 38 is also called a metal ceramic heater (Metal Ceramic Heater: MCH).

[0048] Here, the heater used as the heat source of the hair iron is generally composed of an insulator with barium titanate as the main component. However, since this heater has the characteristic that electric current is difficult to flow when the temperature rises to a certain temperature, it is relatively difficult to perform efficient and linear temperature control.

[0049] In contrast, when the heater 38 has an insulator mainly composed of aluminum oxide, the ease with which current flows is not easily reduced (resistance value increases) even when the temperature rises, so efficient and linear temperature control can be performed. This allows the user to start styling at a desired temperature more quickly.

[0050] The same effect can be expected even in a heater having an insulator composed mainly of zirconium dioxide instead of aluminum oxide.

[0051] The hair ironing section 3 also has a temperature fuse 39. The temperature fuse 39 has a temperature fuse body 391 and a lead wire 392. The temperature fuse body 391 is in contact with the inside of the hair iron body 31. The lead wire 392 is connected to a wiring not shown, and the lead wire 392 extends to the inside of the handle body 21.

[0052] When the hair iron body 31 is overheated, the power supply is cut off in the thermal fuse body 391, and no current flows through the heater 38. In this way, by forcibly stopping the overheating of the hair iron body 31 caused by the heater 38, the occurrence of accidents such as fire can be prevented.

[0053] The hair ironing section 3 also includes a temperature sensor 310. The temperature sensor 310 is in contact with the inner side of the hair iron body 31. A wiring (not shown) is connected to the base end side (-X side in the figure) of the temperature sensor 310 and extends into the inside of the handle body 21. The temperature of the hair iron body 31 detected by the temperature sensor 310 is displayed on the display panel 223 of the handle section 2.

[0054] The temperature sensor is preferably a negative temperature coefficient (NTC) thermistor. In this case, since it is easy to detect a slight temperature change, the user can accurately grasp whether the hair iron body 31 is at a desired temperature through the display panel 223.

[0055] The hair curling unit 3 further includes a light emitting unit 34. By irradiating the scalp with light emitted by the light emitting unit 34, it is expected that the hair growth effect and hair beautifying effect will be produced by activating the cells of the scalp. Figure 4 As shown in FIG. 1 , when the pressing portion 4 is on the upper side (+Y side in the figure), the light emitting portion 34 is arranged at the upper position of the hair iron body 31 (+Y side in the figure). Figure 5 As shown, since the light emitting unit 34 is separated from the heater 38 , it is possible to prevent the light emitting unit 34 from malfunctioning due to the heat generated by the heater 38 .

[0056] The light emitting unit 34 includes an LED (light emitting element) 341, an LED bracket (support body) 342 supporting the LED 341, and an LED cover (support body) 343. The LED 341 is preferably a red LED that emits light with a wavelength of 615 nm or more and 655 nm or less. In addition, a halogen lamp may be used instead of the LED 341 as the light emitting element.

[0057] like Figure 3 As shown, a plurality of LEDs 341 (three in this embodiment) are arranged on the LED bracket 342 along the length direction (X direction in the figure) of the hair iron body 31. With this configuration, the light from the LED 341 can easily irradiate a wider hair area.

[0058] The LED bracket 342 is fixed to the LED cover 343 by screws 344. By supporting the LED 341 from above and below (in the Y direction in the figure), the LED 341 and necessary wiring can be stably held. In addition, the LED bracket 342 and the LED cover 343 are formed of poor thermal conductors, so that excessive heat from the hair iron body 31 can be prevented from being transferred to the LED 341 and the wiring.

[0059] The LED cover 343 has an opening 3431 through which light emitted from the LED 341 passes.

[0060] The hair curling unit 3 further includes a spring pad (force applying member) 36 for applying force to the light emitting unit 34 from the hair curling unit body 31 upward (to the +Y side in the figure). Figure 4 As shown, the spring pad 36 is embedded in the spring groove 3422 formed in the LED bracket 342 .

[0061] As described below, when the user's hair is clamped between the hair iron body 31 and the pressing plate 41 (pressing portion 4), if the hair is pressed toward the hair iron body 31 by the pressing plate 41, the pressing force acts on the LED cover 343 before acting on the hair iron body 31. Therefore, the spring pad 36 contracts and the LED bracket 342 sinks downward (-Y side in the figure). As a result, damage caused by squeezing the hair between the pressing plate 41 and the hair iron body 31 can be suppressed.

[0062] The hair ironing part 3 further includes a silicone pad 35, which is disposed above the hair iron body 31 more than the light emitting part 34. The silicone pad 35 is a stress buffering component having a sheet shape. The silicone pad 35 has the effect of diffusing the light emitted by the LED 341, so that the light can be evenly irradiated to a wide range of the hair wrapped around the hair iron body 31.

[0063] The silicone pad 35 is fixed to the light emitting portion 34 via a silicone pad holder (fixing member) 37. The silicone pad holder 37 is formed of a good thermal conductor, so that the heat of the hair iron body 31 can be well transferred to the hair.

[0064] In addition, the silicone pad holder 37 has an opening (opening) 371 through which the light emitted by the light emitting unit 34 can pass. Thus, the light emitted by the LED 341 of the light emitting unit 34 through the silicone pad 35 can be irradiated onto the hair sandwiched between the hair iron body 31 and the pressing plate 41.

[0065] The silicone pad 35 is embedded in the lower side (-Y side in the figure) of the silicone pad bracket 37. Then, the silicone pad bracket 37 has a plurality of fixing legs 372 (six in this embodiment), and the fixing legs 372 pass through the fixing holes 3421 provided in the same number on the LED bracket 342. At the tip of the fixing legs 372, a fixing claw 3721 wider than the fixing hole 3421 is formed. When the fixing legs 372 are inserted into the fixing holes 3421, the fixing claw 3721 is stuck in the opening edge of the fixing hole 3421, so that the fixing legs 372 are not easy to fall off from the fixing holes 3421. In this way, even if the spring pad 36 contracts and the LED bracket 342 sinks downward (-Y side in the figure), or the silicone pad bracket 37 attempts to move (displace) upward (+Y side in the figure) due to impact, the position of the silicone pad bracket 37 relative to the LED bracket 342 will not change significantly.

[0066] On the other hand, the upper side (+Y side in the figure) higher than the tip of the fixing foot 372 is formed by the shaft portion 3722 having a narrower width than the fixing hole 3421. Therefore, the silicone pad bracket 37 can be displaced in the vertical direction (Z direction in the figure) by the length of the shaft portion 3722 relative to the LED bracket 342.

[0067] And, if Figure 5 As shown, the silicone pad 35 and the silicone pad holder 37 extend from the opening 311 of the hair iron body 31 and are arranged slightly above (on the +Y side in the figure) the upper side (on the +Y side in the figure) of the hair iron body 31 .

[0068] Therefore, when the hair is pressed toward the hair iron body 31 by the pressing plate 41, the pressed hair contacts the silicone pad holder 37 and transmits the pressing force. Then, the silicone pad holder 37 can slightly sink toward the LED holder 342 side (-Y side in the figure) while pressing the silicone pad 35. Therefore, damage caused by the hair being pressed can be more effectively suppressed.

[0069] When the silicone pad bracket 37 is displaced by the length of the shaft portion 3722 of the fixing foot 372, the silicone pad bracket 37 contacts the LED bracket 342 and cannot be further displaced relative to the LED bracket 342. Therefore, the pressing force acts on the LED bracket 342 and the spring pad 36 disposed thereunder. At this time, the spring pad 36 contracts, causing the light emitting portion 34 of the LED bracket 342, the silicone pad 35, and the silicone pad bracket 37 to sink downward.

[0070] At this time, when the spring pad 36 is fully contracted, the outer peripheral surface of the silicone pad bracket 37 is substantially consistent with the outer peripheral surface of the hair iron body 31.

[0071] That is, according to the hair iron 1, before the hair is pressed between the hair iron body 31 and the pressing plate 41, the force of the pressing plate 41 pressing the hair iron body 31 is mitigated by both the spring pad 36 and the silicone pad 35. Therefore, damage to the hair caused by being squeezed can be effectively suppressed.

[0072] Note that the silicone pad 35 may also be fixed to the LED cover 343 by a light-transmitting adhesive, instead of being fixed to the LED bracket 342 by the silicone pad bracket 37 .

[0073] In addition, as a stress relief component, the hair curling unit 3 may also include other elastic cushions to replace the silicone pad 35. In addition, the shape of the stress relief component is not limited to a sheet, and may also be a block (spherical, rectangular, etc.). In this case, as a stress relief component, a plurality of silicone blocks may be fixed to the LED bracket 342, for example, by a fixing component or an adhesive.

[0074] Note that in addition to the silicone pad 35 and the silicone pad holder 37, or instead of it, a silicone pad (stress relief member) may be provided on the side of the hair curling section 3 of the pressing plate 41 of the pressing section 4. In this case, the silicone pad may be fixed to the pressing plate 41 by bonding with an adhesive, welding (thermal welding, ultrasonic welding, high-frequency welding), etc. In addition, a silicone pad and a silicone pad holder may be provided on the side of the hair curling section 3 of the pressing plate 41.

[0075] The pressing portion 4 functions as a hair holding mechanism for holding the hair wound around the hair iron body 31. Figure 1 As shown, the pressing portion 4 includes a pressing plate 41 and a finger rest 42 .

[0076] The pressing plate 41 is a plate-shaped member that is arranged to be able to approach and leave the hair curling section 3 and is configured to press the hair wound around the hair curling section 3 toward the hair curling section 3. The hair can be curled by clamping the hair of the user between the hair curling machine body 31 and the pressing plate 41 or by winding the hair around the hair curling machine body 31. As described above, the light emitting section 34 is arranged above the hair curling machine body 31 (on the +Y side in the figure), so that when the hair is clamped between the hair curling machine body 31 and the pressing plate 41, the light from the light emitting section 34 can be effectively irradiated to the hair.

[0077] In addition, since the pressing plate 41 is formed of a good thermal conductor, the heat from the hair iron body 31 can be transferred to the hair well.

[0078] The finger rest 42 is a part on which the user places his fingers, palms, etc., and is used to perform the operation of moving the pressing plate 41 toward or away from the curling part 3. A plurality of convex strips or grooves (convex and concave) are formed on the outer surface of the finger rest 42 to prevent slipping. In the XY plane in the figure, the finger rest 42 is fixed to the handle part 2 in a rotatable manner. When the finger rest 42 is pressed downward (-Y side in the figure), the tip side of the pressing plate 41 can move upward (+Y side in the figure) (see FIG. 2 ). Figure 2 ). That is, the pressing plate 41 can be separated from the hair curling section 3. In addition, the finger rest 42 is urged upward (to the +Y side in the figure) by a spring (not shown). Thus, when the force pressing the finger rest 42 downward (to the -Y side in the figure) is removed, the finger rest 42 moves upward (to the +Y side in the figure), and the pressing plate 41 fixed to the finger rest 42 moves downward (to the -Y side in the figure). That is, the pressing plate 41 can be brought close to the hair curling section 3.

[0079] Therefore, the user can put the hair between the hair iron body 31 and the pressing plate 41 by pressing the finger rest 42 , and can clamp the hair between the hair iron body 31 and the pressing plate 41 by removing the pressing force.

[0080] The pressing plate 41 has an opening (opening portion) 411 that passes through the pressing plate 41 in the thickness direction thereof. The opening 411 is formed to correspond to the opening 371 of the silicone pad holder 37, that is, to allow the light emitted by the LED 341 to pass through. Therefore, even when the hair is not clamped between the hair iron body 31 and the pressing plate 41 and the hair is wound from above the hair iron body 31 and the pressing plate 41, the light emitted by the LED 341 can be irradiated to the hair.

[0081] Furthermore, when the hair is clamped between the hair iron body 31 and the pressing plate 41 and heated, the steam generated by the hair can be discharged from the opening 411. Therefore, it is possible to prevent the clamped hair from becoming too hot.

[0082] According to the hair iron 1 as described above, it is possible to care for the hair while minimizing damage to the hair.

[0083] Hereinafter, various modified examples of the hair iron 1 of the present disclosure will be described, but the differences from the above-mentioned structural example will be mainly described, and the description of the same matters will be omitted.

[0084] (Variant 1)

[0085] Figure 6 This is a perspective view of the appearance of a hair iron according to Modification 1. Figure 7 This is a perspective view of the appearance of a hair iron according to Modification 1. Figure 8 This is a view of the hair curling unit from the tip side (+X direction in the figure) with the cap removed. Figure 8 In the figure, structures other than the perm section are omitted.

[0086] In the modification 1 of the hair iron 1, the following structure is different, and other than that, the structure is the same as the above-mentioned structure example.

[0087] That is, Figure 6 As shown, the hair iron 1 does not have the pressing part 4, but instead has a suction part as a hair holding mechanism. The suction part has a suction port 312, a fan part not shown, and an exhaust port not shown. Figure 7 and Figure 8 As shown, the suction port 312 is provided in the hair iron body 31. In addition, the fan unit is provided inside the handle body 21, for example, and the exhaust port is formed to connect the inside and the outside of the handle body 21.

[0088] When the user presses the suction button 224 provided on the operation part 22 of the handle part 2 while winding the hair around the hair iron body 31, the fan part (not shown) is activated, and air is sucked into the inside of the hair iron body 31 from the suction port 312, and air is discharged from the exhaust port. At this time, the user's hair wound around the hair iron body 31 is attracted to the outer peripheral surface of the hair iron body 31 by the flow of the air sucked into the hair iron body 31. Therefore, even if the hair iron 1 does not have the pressing part 4, the hair can be wound and held on the outer peripheral surface of the hair iron body 31.

[0089] Therefore, the user does not need to frequently press the finger rest 42 , which can prevent the user from losing balance when grasping the handle portion 2 or feeling finger fatigue due to pressing the finger rest 42 .

[0090] Note that the hair iron body 31 may also have a plurality of suction ports 312. In this case, since the hair can be adsorbed at multiple locations, styling can be performed more stably. In addition, since the force of adsorbing the hair can be dispersed through the plurality of suction ports 312, damage to the hair can be reduced.

[0091] In the modification 1, the hair is less likely to be damaged by being squeezed because the hair iron 1 does not have the pressing part 4. Thus, in the hair iron body 31, the silicone pad 35, the silicone pad holder 37 and the spring pad 36 are omitted.

[0092] like Figure 6 As shown, in the hair iron body 31, the LED cover 343 is exposed from the opening 311 instead of the silicone pad 35 and the silicone pad support 37. The LED cover 343 has a light-transmitting cover 3432, which is configured to protect the LED 341 and transmit the light emitted by the LED 341.

[0093] In addition, if Figure 8 As shown, the LED bracket 342 is directly supported by the hair iron body 31 without the spring pad 36 .

[0094] As described above, according to Modification 1, it is possible to provide a hair iron 1 that can reduce user fatigue and suppress hair damage.

[0095] (Variant 2)

[0096] In the modification 2 of the hair iron 1, the following structure is different, and other than that, the structure is the same as the above-mentioned structure example.

[0097] That is, the hair iron 1 includes a brush portion as a hair holding mechanism instead of the pressing portion 4. The brush portion is provided over a wide range of the outer peripheral surface of the hair iron body 31 and has a plurality of brushes (protrusions) protruding in the radial direction of the hair iron body 31. The brush portion is formed of a poor conductor of heat.

[0098] When the user winds the hair around the hair iron body 31, the hair enters between the multiple brushes of the brush part and can maintain the state of winding. The user can put the hand that is not holding the handle body 21 from the brush of the brush part to the hair, so that the state of winding the hair can be maintained more stably. At this time, even if the hair iron body 31 is heated, the tip of the brush of the brush part is unlikely to reach a high temperature, so it is possible to prevent the user's hand and the like from being exposed to high temperature.

[0099] Compared with clamping the hair between the pressing portion 4 and the hair iron body 31, holding the hair with a brush allows the user to style the hair more intuitively.

[0100] In addition, similar to the first modification, the hair is less likely to be damaged by being squeezed because the hair iron 1 does not have the pressing portion 4. Therefore, the silicone pad 35, the silicone pad holder 37 and the spring pad 36 are omitted in the hair iron body 31. Note that the structure of the light emitting portion 34 may be the same as that of the first modification.

[0101] Thus, according to the second modification, it is possible to provide a hair iron 1 that can perform intuitive styling while suppressing hair damage.

[0102] In addition, the present invention can also be provided in various ways as described below.
