Detailed Description

The following uses to illustrate embodiments of the utility model. Various features shown in the embodiments shown below may be combined with each other.

A hair iron according to an embodiment of the present disclosure will be described with reference to fig. 1 to 5. Fig. 1 is a perspective view showing a hair iron. Fig. 2 is a perspective view showing a state in which the tip side of the pressing plate is lifted.

Fig. 3 and 4 are exploded perspective views of the hair iron. Fig. 5 is a view of the permanent wave part as seen from the tip side (+x direction in the drawing) in a state where the cover is removed. In fig. 5, the structure other than the hair waving section is omitted.

In the following description, the good heat conductor is a material having high heat conductivity, and examples thereof include aluminum, copper, graphite sheet, aluminum nitride, and the like. The poor heat conductor is a material having low heat conductivity, and examples thereof include polyethylene terephthalate, polycarbonate, and ABS resin.

As shown in fig. 1, the hair iron 1 includes a handle portion 2, a hair waving portion 3, and a pressing portion 4. The hair iron 1 further includes a cover 6 and a power supply unit 7.

In a state where the hair waving portion 3 is heated, for example, the hair iron 1 can curl hair by winding the hair.

The cover 6 is disposed on the front end side (+x side in the drawing) of the hair iron 1, and is formed of a defective conductor of heat. In this way, the user can grasp the handle portion 2 and the cover 6 at the same time, and thus can stably perform the molding even if the force of grasping the handle portion 2 is weak.

The handle portion 2 is configured to be gripped by a user. As shown in fig. 2, the handle portion 2 includes a handle body 21, an operation portion 22, and a leg portion 23. The handle portion 2 (handle body 21) includes wiring, a board, and the like, not shown, inside. The handle portion 2 is formed of a poor conductor of heat to prevent heat from the hair waving portion 3 from being transferred to a user's hand or wiring, a substrate, etc. inside the handle body 2.

The handle body 21 has an elongated shape for the convenience of grasping by a user, and is formed such that a tip side (+x side in the drawing) is thicker than a base side (X side in the drawing). The surface of the handle body 21 can also be covered with a sheet having a cushioning function and/or an anti-slip function. Thereby, the user can grasp the handle body 21 more stably.

The operation unit 22 includes a power button 221 and a temperature adjustment button 222 that are operated by a user. The operation unit 22 includes a display panel 223 for displaying the temperature of the hair waving unit 3.

The leg portion 23 is a convex portion formed on the opposite side (the-Y side in the drawing) of the hair iron 1 from the pressing portion 4. The leg 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 an upper side, the leg portion 23 and the cover 6 contact the table or the like, and the whole of the hair iron 1 can be supported. At this time, since the hair waving portion 3 can be prevented from coming into contact with a table or the like, the hair waving device 1 can be mounted on the table or the like even in a state where the hair waving portion 3 is heated. Further, since the leg portion 23 is formed on the opposite side to the pressing portion 4, the pressing portion 4 is less likely to be an obstacle when the hair iron 1 is placed on a table or the like.

Note that, the portion constituting the support mechanism together with the leg portion 23 may be a portion (base end portion) on the base end side (X side in the drawing) of the handle main body 21 instead of the cap 6 on the tip end side. In this case, if a weight is provided inside or outside the base end portion of the handle body 21, the entire hair iron 1 can be stably supported by the leg portion 23 and the base end portion of the handle body 21 when the hair iron 1 is mounted on a table or the like. At this time, the leading end side (+x side in the drawing) of the hair waving section 3 is lifted obliquely upward against gravity, so that the hair waving section 3 can be prevented from touching a table top or the like.

A power supply unit 7 is attached to the base end side (X side in the drawing) of the handle body 21. When the power supply unit 7 is connected to a power source, not shown, electric power is supplied to the hair iron 1. The electric power supplied from the power supply unit 7 is supplied to each unit via a wiring or the like, not shown, inside the handle body 21.

The hair waving section 3 is provided on the tip side (+x side in the drawing) of the handle section 2, and is used when winding hair and curling it. As shown in fig. 5, the hair waving section 3 includes a hair waving device main body (main body) 31, a pair of electrodes 32, and a pair of heaters 38.

The hair iron body 31 is formed in a cylindrical shape to wind the hair of the user to be curled. Since the hair iron body 31 is formed of a good conductor of heat, the heat emitted from the heater 38 can be well transferred to the hair wound around the hair iron body 31.

The pair of electrodes 32 are provided at opposing positions on the circumferential surface of the hair iron main body 31, specifically, at opposing positions on the sides (in the drawing, +z side, -Z side) of the hair iron main body 31 when the pressing portion 4 side is set to the upper side (in the drawing, +y side). In addition, a pair of electrodes 32 are exposed from the hair iron main body 31. Therefore, the hair wound around the hair iron main body 31 can be brought into contact with the electrode 32 at the positions on the sides.

Since the exposed surface of each electrode 32 is formed as a curved surface, the curl shape of the hair wound around the hair iron main body 31 is less likely to be uneven.

Each electrode 32 is elongated and is provided along the longitudinal direction (X direction in the drawing) of the hair iron main body 31. Thus, even in the case where the hair of the user is short, as long as the hair can be wound around half of the circumference of the hair iron main body 31, the hair can be brought into contact with the two electrodes 32 in a solid state.

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

Each electrode 32 has a function of introducing or extracting ions into or from hair. Specifically, when a pulse-shaped current flows in a state where hair is wound around the hair iron body 31, that is, in a state where hair contacts each electrode 32, ions are introduced from the electrode 32 to the hair. Thus, the cosmetic ingredients contained in hair care and the like can be ionized and sufficiently penetrated into the hair. In addition, the electrode has the function of adsorbing charged dirt on hair.

An electrode holder 33 is disposed between each electrode 32 and the hair iron main body 31. The electrode holder 33 is formed of a poor conductor of heat, and can prevent the heat from the hair iron main body 31 from being transferred to excessively heat the electrode 32.

The electrodes 32 are inserted from the distal end side (+x side in the figure) or the proximal end side (X side in the figure) into electrode holders 33 fixed to the hair iron main body 31 by screws not shown, and are fixed in the up-down direction (Y direction in the figure) and the left-right direction (Z direction in the figure). A cap 6 is fixed to the tip side (+x side in the drawing) of each electrode 32, and a handle 2 is fixed to the base side (X side in the drawing) and is fixed to the hair iron main body 31. Thereby, the electrodes 32 are prevented from falling off from the hair iron main body 31 in each direction.

The pair of heaters 38 generate heat by electric energy supplied through the power supply unit 7. The pair of heaters 38 are provided at positions inside the hair iron main body 31, and are disposed opposite to each other at positions further inside than the pair of electrodes 32, respectively. According to such an arrangement, the heater 38 is arranged at a position inside the hair iron main body 31, that is, on the pressing portion 4 side (upper side +y side in the drawing), and the hair sandwiched between the hair iron main body 31 and the pressing plate 41 (pressing portion 4) is prevented from being overheated. That is, damage to hair caused by heat or loss of moisture can be suppressed.

Each heater 38 is elongated and is provided along the longitudinal direction (Y direction in the drawing) of the hair iron main body (main body) 31. A heater pressing piece 381 is provided inside each heater 38 to prevent the heater 38 from being separated from the hair iron main body 31. By providing the two-piece heater 38 in this way, heat can be easily and rapidly transferred to the whole hair iron body 31. Therefore, inconvenience of the user due to the longer waiting time can be reduced, and a desired shaping can be achieved.

Each heater 38 has a heating element not shown and an insulator covering the heating element.

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 cermet heater (METAL CERAMIC HEATER: MCH).

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

In contrast, in the case where the heater 38 has an insulator composed mainly of alumina, the ease of current flow is not easily reduced (resistance value is increased) even when the temperature is increased, and therefore efficient and linear temperature control can be performed. In this way, the user can more quickly begin the build at the desired temperature.

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

The hair waving part 3 further has a temperature fuse 39. The thermal fuse 39 has a thermal fuse body 391 and a wire 392. The temperature fuse body 391 is in contact with the inside of the hair iron body 31. The lead 392 is connected to a wiring not shown, and the lead 392 extends to the inside of the handle body 21.

When the hair iron body 31 is overheated, the current is cut off in the temperature fuse body 391, and no current flows through the heater 38. By forcibly stopping the overheating of the hair iron main body 31 by the heater 38 in this way, it is possible to prevent accidents such as fire.

The hair waving part 3 further has a temperature sensor 310. The temperature sensor 310 is in contact with the inside of the hair iron body 31. A wiring (not shown) is connected to the base end side (X side in the drawing) of the temperature sensor 310, and extends into 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 part 2.

The temperature sensor is preferably a negative temperature coefficient (Negative Temperature Coefficient: NT C) thermistor. In this case, since a minute temperature change is easily detected, the user can grasp with high accuracy whether the hair iron main body 31 is at a desired temperature via the display panel 223.

The hair waving part 3 further has a light emitting part 34. By irradiating the scalp with the light emitted from the light emitting portion 34, a hair growth effect and a hair styling effect can be expected by activating the cells of the scalp. As shown in fig. 4, when the pressing portion 4 side is upward (+y side in the drawing), the light emitting portion 34 is provided at a position above the hair iron main body 31 (+y side in the drawing). As shown in fig. 5, since the light emitting portion 34 is separated from the heater 38, it is possible to prevent the light emitting portion 34 from malfunctioning due to heat generated by the heater 38.

The light emitting section 34 includes an LED (light emitting element) 341, an LED holder (support) 342 for supporting the LED341, and an LED cover (support) 343. The LED341 is preferably a red LED that emits light having a wavelength of 615nm or more and 655nm or less. In addition, a halogen lamp may be used for the light emitting element instead of the LED341.

As shown in fig. 3, a plurality of LEDs 341 (three in the present embodiment) are provided on the LED holder 342 along the longitudinal direction (X direction in the drawing) of the hair iron main body 31. With this configuration, light from the LEDs 341 can be easily irradiated to a wide hair area.

The LED holder 342 is fixed to the LED cover 343 by a screw 344. By supporting the LED341 from above and below (Y direction in the drawing), the LED341 and necessary wiring can be stably held. In addition, the LED holder 342 and the LED cover 343 are formed of poor conductors of heat, so that excessive transfer of heat from the hair iron main body 31 to the LEDs 341 and the wires can be prevented.

The LED cover 343 has an opening 3431 through which light emitted from the LED341 passes.

The hair waving section 3 further includes a spring pad (urging member) 36 for urging the light emitting section 34 upward (+y side in the drawing) from the hair waving device main body 31. As shown in fig. 4, the spring pad 36 is embedded in a spring groove 3422 formed in the LED support 342.

As described below, when the hair of the user is held between the hair iron main body 31 and the pressing plate 41 (pressing portion 4), if the hair is pressed toward the hair iron main body 31 by the pressing plate 41, the pressing force acts on the LED cover 343 before acting on the hair iron main body 31. Accordingly, the spring pad 36 contracts, and the LE D holder 342 sinks downward (on the-Y side in the drawing). Thereby, damage caused by squeezing hair between the pressing plate 41 and the hair iron main body 31 can be suppressed.

The hair waving section 3 further includes a silica gel pad 35 provided above the hair waving device main body 31 than the light emitting section 34. The silica gel pad 35 is a stress buffering member having a sheet shape. The silica gel pad 35 has an effect of diffusing light emitted from the LED341 so that the light can be uniformly irradiated to a wide range of hair wound on the hair iron body 31.

The silica gel pad 35 is fixed to the light emitting section 34 by a silica gel pad holder (fixing member) 37. The silica gel pad holder 37 is formed of a good conductor of heat, so that the heat of the hair iron body 31 can be well transferred to the hair.

The silica gel pad holder 37 includes an opening 371 through which light emitted from the light emitting section 34 can pass (opening section). Thus, the light transmitted through the silica gel pad 35 from the LED341 of the light emitting part 34 can be irradiated to the hair held between the hair iron main body 31 and the pressing plate 41.

The silica gel pad 35 is embedded in the underside (the-Y side in the figure) of the silica gel pad holder 37. Then, the silica gel pad holder 37 has a plurality of fixing pins 372 (six in this embodiment), and the fixing pins 372 pass through the fixing holes 3421 provided in the same number on the LED holder 342. At the front end of the fixing leg 372, a fixing claw 3721 wider than the fixing hole 3421 is formed. In a state where the fixing leg 372 is inserted into the fixing hole 3421, the fixing claw 3721 is caught at the opening edge of the fixing hole 3421, and thus the fixing leg 372 is not easily detached from the fixing hole 3421. In this way, even if the spring pad 36 contracts to sink the LED holder 342 downward (in the drawing, the-Y side), or if the silicone pad holder 37 tries to move upward (in the drawing, +y side) due to an impact or the like, the position of the silicone pad holder 37 with respect to the LED holder 342 does not change significantly.

On the other hand, an upper side (+y side in the drawing) higher than the tip of the fixing leg 372 is formed by a shaft portion 3722 narrower in width than the fixing hole 3421. Accordingly, the silicone pad holder 37 can be displaced in the vertical direction (Z direction in the drawing) by the length of the shaft portion 3722 with respect to the LED holder 342.

As shown in fig. 5, the silica gel pad 35 and the silica gel pad holder 37 extend from the opening 311 provided in the hair iron main body 31, and are provided slightly above (in the figure, +y side) the upper surface (in the figure, +y side) of the hair iron main body 31.

Therefore, when the hair is pressed toward the hair iron main body 31 by the pressing plate 41, the pressed hair contacts the silica gel pad holder 37, transmitting the pressing force. Then, the silica gel pad holder 37 can slightly sink toward the LED holder 342 side (the-Y side in the drawing) while pressing the silica gel pad 35. Therefore, damage due to hair being pressed can be suppressed more firmly.

When the silicone pad holder 37 is displaced by the length of the shaft portion 3722 of the fixing leg 372, the silicone pad holder 37 is in contact with the LED holder 342 and cannot be further displaced with respect to the LED holder 342. Accordingly, the pressing force acts on the LED holder 342 and the spring pad 36 disposed thereunder. At this time, the spring pad 36 contracts, causing the light emitting part 34 including the LED holder 342, the silica gel pad 35, and the silica gel pad holder 37 to sink downward.

At this time, when the spring pad 36 is completely contracted, the outer circumferential surface of the silica gel pad holder 37 substantially coincides with the outer circumferential surface of the hair iron main body 31.

That is, according to the hair iron 1, the force of the pressing plate 41 to press the hair against the hair iron body 31 is relaxed by both the spring pad 36 and the silica gel pad 35 before the hair is pressed between the hair iron body 31 and the pressing plate 41. Therefore, damage due to hair being pressed can be effectively suppressed.

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

The permanent wave portion 3 may be provided with another cushion having elasticity as a stress relaxation member instead of the silica gel pad 35. The shape of the stress relaxation member is not limited to a sheet shape, and may be a block shape (spherical shape, rectangular parallelepiped shape, or the like), for example. In this case, as the stress relaxation member, a plurality of silicone blocks may be fixed to the LED holder 342 by a fixing member or an adhesive, for example.

Note that, in addition to or instead of the silica gel pad 35 and the silica gel pad holder 37, a silica gel pad (stress relaxing member) may be provided on the side surface of the hair waving section 3 of the pressing plate 41 of the pressing section 4. At this time, the silicone pad can be fixed to the pressing plate 41 by adhesion of an adhesive, welding (thermal welding, ultrasonic welding, high-frequency welding), or the like. In addition, a silica gel pad and a silica gel pad holder may be provided on the side surface of the permanent wave part 3 of the pressing plate 41.

The pressing portion 4 functions as a hair holding mechanism for holding the state where the hair is wound around the hair iron main body 31. As shown in fig. 1, the pressing portion 4 includes a pressing plate 41 and a finger rest 42.

The pressing plate 41 is provided so as to be able to approach and separate from the hair waving section 3, and is a plate-like member configured to press hair wound around the hair waving section 3 toward the hair waving section 3. The hair of the user can be curled by sandwiching the hair between the hair iron body 31 and the pressing plate 41 or by winding the hair around the hair iron body 31. As described above, since the light emitting portion 34 is provided at a position above (on the +y side in the drawing) the hair iron body 31, the light from the light emitting portion 34 can be efficiently irradiated to the hair even when the hair iron is interposed between the hair iron body 31 and the pressing plate 41.

Further, since the pressing plate 41 is formed of a good conductor of heat, the heat from the hair iron main body 31 can be transferred to the hair with good efficiency.

The finger rest 42 is a member for placing a finger, palm, or the like of a user for performing an operation of moving the pressing plate 41 toward or away from the hair waving section 3. A plurality of protrusions or grooves (concavities and convexities) are formed on the outer surface of the finger rest 42 to prevent sliding. In the XY plane of the drawing, the finger rest 42 is rotatably fixed to the handle portion 2. When the finger rest 42 is pressed downward (the-Y side in the drawing), the tip side of the pressing plate 41 can be moved upward (the +y side in the drawing) (see fig. 2). That is, the pressing plate 41 can be separated from the hair waving section 3. The finger rest 42 is biased upward (toward +y in the figure) by a spring (not shown). Thus, when the force pressing down the finger rest 42 downward (on the-Y side in the drawing) is removed, the finger rest 42 moves upward (on the +y side in the drawing), and the pressing plate 41 fixed to the finger rest 42 moves downward (on the-Y side in the drawing). That is, the pressing plate 41 can be brought close to the permanent wave unit 3.

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

The pressing plate 41 has an opening (opening portion) 411 penetrating in the thickness direction thereof. The opening 411 is formed to correspond to the opening 371 of the silica gel pad holder 37, that is, to pass light emitted from the LED 341. Therefore, even when the hair is wound from above the hair iron body 31 and the pressing plate 41 without sandwiching the hair between the hair iron body 31 and the pressing plate 41, the light emitted from the LED341 can be irradiated to the hair.

Further, when the hair is heated while being sandwiched between the hair iron main body 31 and the pressing plate 41, water vapor generated from the hair can be discharged from the opening 411. Therefore, the temperature of the held hair can be prevented from being excessively high.

According to the hair iron 1 as described above, it is possible to minimize damage to hair and to care for hair.

Hereinafter, each modification of the hair iron 1 of the present disclosure will be described, but differences from the above-described structural examples will be mainly described, and the description thereof will be omitted for the same matters.

Modification 1

Fig. 6 is an external perspective view of a hair iron according to modification 1. Fig. 7 is an external perspective view of a hair iron according to modification 1. Fig. 8 is a view of the permanent wave part as seen from the tip side (+x direction in the drawing) in a state where the cover is removed. In fig. 8, the structure other than the hair waving section is omitted.

The hair iron 1 of modification 1 is identical to the above-described configuration except that the following configuration is different.

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

When the user presses the suction button 224 provided on the operation portion 22 of the handle portion 2 while winding the hair around the hair iron main body 31, a fan portion, not shown, is activated, and air is sucked from the suction port 312 into the hair iron main body 31 and discharged from the exhaust port. At this time, the hair of the user wound around the hair iron main body 31 is adsorbed to the outer circumferential surface of the hair iron main body 31 by the flow of the air sucked into the hair iron main body 31. Therefore, even if the hair iron 1 does not have the pressing portion 4, the hair can be wound around and held by the outer peripheral surface of the iron body 31.

Accordingly, the user does not need to frequently press the finger rest 42, which can prevent the user from losing balance while gripping the handle 2 or feel finger fatigue by pressing the finger rest 42.

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

In modification 1, since the hair iron 1 does not have the pressing portion 4, the hair is less likely to be damaged by being pressed. In this way, the silica gel pad 35, the silica gel pad holder 37 and the spring pad 36 are omitted from the hair iron main body 31.

As shown in fig. 6, in the hair iron main body 31, the LED cover 343 is exposed from the opening 311 instead of the silicone pad 35 and the silicone pad holder 37. The LED cover 343 has a light-transmitting cover 3432, and is configured to protect the LED341 and to transmit light emitted from the LED 341.

As shown in fig. 8, the LED holder 342 is directly supported by the hair iron main body 31 without the spring pad 36.

Thus, according to modification 1, the hair iron 1 capable of reducing fatigue of the user and suppressing damage to the hair can be provided.

Modification 2

The hair iron 1 of modification 2 is identical to the above-described configuration except that the following configuration is different.

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 in 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.

When the user winds the hair around the hair iron main body 31, the hair enters between the brushes of the brush section, and the wound state can be maintained. The user can put the hand, which is not holding the handle body 21, on the hair from the brush of the brush portion, so that the wound state of the hair can be maintained more stably. At this time, even if the hair iron main body 31 is heated, the tip of the brush portion is hard to reach a high temperature, so that the user's hand or the like can be prevented from being exposed to a high temperature.

Holding hair by the brush enables a user to style more intuitively than holding hair between the pressing part 4 and the hair iron main body 31.

In addition, since the hair iron 1 does not have the pressing portion 4, the hair is less likely to be damaged by being pressed, as in modification 1. Therefore, in the hair iron main body 31, the silica gel pad 35, the silica gel pad holder 37 and the spring pad 36 are omitted. Note that the structure of the light emitting portion 34 may be the same as that of modification 1.

Thus, according to modification 2, the hair iron 1 capable of intuitively styling and suppressing damage to hair can be provided.
