[0010] Hereinafter, embodiments will be described in detail with reference to the drawings. However, unnecessary detailed description may be omitted. For example, detailed description of already well-known matters or redundant description of substantially the same configuration may be omitted.

[0011] The accompanying drawings and the following description are provided to enable those skilled in the art to fully understand the present disclosure, and are not intended to limit the subject matter described in the claims.

[0012] Furthermore, the following embodiments and their modifications include similar components, and therefore, in the following, the same reference numerals will be used to denote the similar components, and redundant explanations will be omitted.

[0013] (Embodiment) FIG. 1 is a diagram showing an example of a hair iron 1 according to an embodiment, and is a diagram schematically showing the hair iron 1 in a closed state. FIG. 2 is a diagram showing an example of a hair iron 1 according to an embodiment, and is a diagram schematically showing the hair iron 1 in an open state. FIG. 3 is a diagram schematically showing a state in which hair H is being treated using the example of the hair iron 1 according to the embodiment. The hair iron 1 according to the present embodiment includes a main body 10 that is elongated in one direction (hereinafter referred to as the front-to-rear direction). As shown in FIGS. 1 and 2 , the main body 10 includes a first arm 11 and a second arm 12 that are connected via a hinge 13 so as to be expandable (openable and closable) in a substantially V-shape. The first arm 11 and the second arm 12 are rotated relative to each other via the hinge 13, allowing the tips of the first arm 11 and the second arm 12 to move toward and away from each other.

[0014] That is, in this embodiment, as the first arm portion 11 and the second arm portion 12 rotate relative to each other, the first hair clamping surface (hair clamping surface: hair holding surface) 1131 and the second hair clamping surface (hair clamping surface: hair holding surface) 1231 described below can be moved closer to or farther away from each other.

[0015] Furthermore, a first gripping portion (grip) 112 and a second gripping portion (grip) 122 are provided on the hinge portion 13 side (rear side of the hair iron 1) of the first arm portion 11 and the second arm portion 12, respectively. A first hair clamping portion 113 and a second hair clamping portion 123 are provided on the tip side (front side of the hair iron 1) of the first arm portion 11 and the second arm portion 12, respectively.

[0016] The first hair clamping portion 113 and the second hair clamping portion 123 each have a first hair clamping surface 1131 and a second hair clamping surface 1231 that can move toward or away from each other (can be made to face each other) when the first arm portion 11 and the second arm portion 12 are rotated relative to each other. Specifically, as shown in FIG. 3 , when the first arm portion 11 and the second arm portion 12 are closed, the first hair clamping surface 1131 and the second hair clamping surface 1231 are parallel to each other and are configured to clamp the user U's hair H. The first hair clamping surface 1131 and the second hair clamping surface 1231 can be formed, for example, using an aluminum plate. In this case, the surface of the aluminum plate is anodized or glass-coated. When alkaline water is used, it is desirable to apply a ceramic coating to the surface of the aluminum plate, which has higher chemical resistance than glass-based coatings.

[0017] In addition, in this embodiment, the first hair clamping surface 1131 and the second hair clamping surface 1231 are formed in an approximately rectangular shape that is elongated in the front-to-back direction when viewed along the direction in which they face each other (the normal direction of the first hair clamping surface 1131 and the second hair clamping surface 1231) when the first arm unit 11 and the second arm unit 12 are closed.

[0018] It is preferable that the first hair clamping surface 1131 and the second hair clamping surface 1231 are configured to be able to float using a float mechanism such as a coil spring, or be able to be flexibly deformed, thereby preventing excessive load from being applied to the hair H clamped between the first hair clamping surface 1131 and the second hair clamping surface 1231. The flexibly deformable configuration can be achieved, for example, by arranging multiple elongated plates in the width direction intersecting the front-rear direction so that each plate can be independently floated in the up-down direction.

[0019] Fig. 4 is a diagram schematically illustrating an example of the liquid release unit 20 of the hair iron according to the embodiment. In this embodiment, as shown in Fig. 4, a first heater 114 and a second heater 124 serving as heating units are provided on the back side (the side opposite to the first hair clamping surface 1131 and the second hair clamping surface 1231) of the first hair clamping unit 113 and the second hair clamping unit 123. It is not necessary to heat both the first hair clamping unit 113 and the second hair clamping unit 123 with the heaters; it is also possible to heat only one of them.

[0020] As described above, in this embodiment, the hair iron 1 has a main body 10, which has a heating section (first heater 114 and second heater 124) and a hair clamping section (first hair clamping section 113 and second hair clamping section 123) that can clamp the hair H while heated by the heating section.

[0021] The first arm portion 11 and the second arm portion 12 are provided with a first housing 111 and a second housing 121 that form the outer shells of the first arm portion 11 and the second arm portion 12, respectively.

[0022] In addition, a power cord (not shown) is attached to the rear end 10a of the main body 10 of the hair iron 1, and this power cord is electrically connected to a control device 30 that controls the heaters (first heater 114, second heater 124) via lead wires (wiring) 40.

[0023] Furthermore, an operation switch 14 is provided on the first arm 11 of the hair iron 1, and power to the heaters (first heater 114, second heater 124) can be turned on and off by operating this operation switch 14. The heaters (first heater 114 and second heater 124), sensors (described below), etc. are preferably sealed with a ceramic material such as alumina that is resistant to alkali corrosion.

[0024] In addition, it is possible to make the hair iron into a cordless type by incorporating a battery (rechargeable battery) or storing replaceable (non-rechargeable) dry batteries inside the main body 10.

[0025] 3, when using such a hair iron 1, a user U grips the gripping portions (first gripping portion 112 and second gripping portion 122) and clamps the hair H between the first hair clamping surface 1131 and the second hair clamping surface 1231. With the hair H clamped between the first hair clamping surface 1131 and the second hair clamping surface 1231, heat generated by the first heater 114 and the second heater 124 is applied to the hair H via the first hair clamping surface 1131 and the second hair clamping surface 1231, thereby performing a treatment on the hair H (for example, curling or straightening the hair H).

[0026] In addition, hair H can be straightened, for example, by clamping the root side of the hair H between the first hair clamping surface 1131 and the second hair clamping surface 1231 with the hair iron 1 and sliding it along the hair H while pulling it down towards the ends.

[0027] As described above, the hair iron 1 according to the present embodiment has gripping portions (first gripping portion 112 and second gripping portion 122) having hair gripping surfaces (first hair clamping surface 1131 and second hair clamping surface 1231) for gripping the hair H, and heating portions (first heater 114 and second heater 124) for heating the hair H gripped by the gripping portions (first gripping portion 112 and second gripping portion 122) on the hair gripping surfaces (first hair clamping surface 1131 and second hair clamping surface 1231). The hair iron 1 according to the present embodiment has such a configuration that it thermally sets the hair H, and performs hair styling (treatment of the hair H) by thermally setting the hair H.

[0028] Here, in this embodiment, it is possible to further improve the treatment effect on the hair H while minimizing heat damage to the hair H caused by the treatment.

[0029] Specifically, as shown in Fig. 4, the hair iron 1 includes a liquid discharge unit (produced water discharge unit) 20 provided in the main body 10. The liquid discharge unit 20 has a discharge port (produced water discharge unit) 21 that can discharge acidic water or alkaline water to the outside of the main body 10.

[0030] Furthermore, in this embodiment, the liquid release section 20 is provided with a storage section (liquid supply tank) 22 capable of storing liquid, a flow path 23 connecting the storage section 22 with the release port 21, and a liquid delivery pump (liquid delivery section) 24 provided in the flow path 23 and capable of delivering the liquid in the storage section 22 to the release port 21 side.

[0031] The reservoir 22 can store raw water such as tap water or well water. One method of supplying liquid to the reservoir 22 is to removably hold a container that constitutes the reservoir 22 on the main body 10, remove the container from the main body 10, store liquid in the container, and then attach the container to the main body 10. Another method is to provide the main body 10 with an opening that is closed openably and closably with a lid member so as to communicate with the reservoir 22, and then remove the lid member to inject the liquid through the opening, thereby supplying the liquid to the reservoir 22.

[0032] The liquid such as raw water stored in the storage section 22 is supplied to the discharge port 21 through the flow path 23. In this manner, in the present embodiment, the flow path 23 extending from the storage section 22 to the discharge port 21 serves as the main flow path 231 of the liquid discharge section 20. In other words, the flow path 23 includes one main flow path 231 extending from the storage section 22 to the discharge port 21.

[0033] A liquid delivery pump (liquid delivery unit) 24 is connected to the flow path 23 downstream of the storage unit 22, and by driving this liquid delivery pump (liquid delivery unit) 24, the raw water or other liquid stored in the storage unit 22 is delivered to the downstream side of the flow path 23. This liquid delivery pump (liquid delivery unit) 24 is electrically connected to a control device 30 via wiring (not shown), and the control device 30 controls the supply of power and operation (drive).

[0034] Furthermore, in this embodiment, a liquid generating unit 25 is disposed downstream of the liquid feeding pump (liquid feeding unit) 24 in the flow path 23. By driving the liquid feeding pump (liquid feeding unit) 24, a liquid such as raw water stored in the storage unit 22 is supplied to the liquid generating unit 25. The liquid generating unit 25 generates at least one of acidic water and alkaline water. The acidic water or alkaline water generated in the liquid generating unit 25 is sent (transmitted) to the discharge port 21 by the liquid feeding pump (liquid feeding unit) 24 and discharged from the discharge port 21 toward the hair H. Preferably, the acidic water or alkaline water is discharged from the discharge port 21 in the form of a mist. This configuration can be achieved, for example, by using the discharge port 21 as the outlet of a spray nozzle or by generating ultrasonic atomization using an ultrasonic element. The discharge of the liquid (acidic water or alkaline water) from the discharge port 21 toward the hair H can be performed continuously or intermittently. Such continuous or intermittent operation can be controlled by, for example, the control device 30.

[0035] Furthermore, in this embodiment, an ion exchange unit 251 capable of performing ion exchange with the liquid passing through the inside is used as the liquid generating unit 25. That is, the liquid discharging unit 20 is exemplified, in which the liquid generating unit 25 is provided with the ion exchange unit 251.

[0036] This ion exchange section 251 can be provided with a cation exchange section 2511 having a cation exchange resin regenerated to H type, or with an anion exchange section 2512 having an anion exchange resin regenerated to OH type.

[0037] For example, if the ion exchange unit 251 is provided with a cation exchange unit 2511 having a cation exchange resin that has been regenerated to H type, when a liquid such as raw water is passed through the cation exchange unit 2511, the cations contained in the liquid such as raw water and the H ions in the ion exchange resin undergo ion exchange to produce acidic water.

[0038] On the other hand, if the ion exchange section 251 is equipped with an anion exchange section 2512, when a liquid such as raw water is passed through the anion exchange section 2512, an ion exchange occurs between the anions contained in the liquid such as raw water and the OH ions in the ion exchange resin, producing alkaline water.

[0039] As described above, in this embodiment, the liquid generating unit 25 includes an ion exchange unit 251 incorporating an ion exchange resin that generates acidic water or alkaline water. Note that the ion exchange unit 251 may include a member capable of ion exchange, such as an ion exchange fiber or an ion exchange filter carrying an ion exchange resin. In other words, the ion exchange unit 251 can be formed using at least one type of member capable of ion exchange, such as an ion exchange resin, an ion exchange fiber, or an ion exchange filter carrying an ion exchange resin.

[0040] In this embodiment, a replenisher liquid, which is tap water or the like supplemented with saline solution as an electrolyte whose concentration has been adjusted in advance, is stored as raw water in the reservoir 22. Note that raw water may be supplied to the reservoir 22 containing salt tablets, thereby generating a replenisher liquid supplemented with saline solution in the reservoir 22. In this manner, a liquid to which salt has been added as an electrolyte, i.e., a liquid with an increased amount of dissolved ions, is supplied to the liquid generator 25.

[0041] In this manner, in this embodiment, the ion exchange capacity can be adjusted by the electrolyte (salt).

[0042] In this way, even if the water, such as tap water, is soft water with a low hardness content, it is possible to generate acidic water or alkaline water with a desired pH range (a pH appropriate for treating the hair H). In other words, even if tap water from a soft water area is used, the necessary amount of acid or alkaline liquid can be supplied to the hair H when treating the hair H with the hair iron 1.

[0043] When treating hair H using a hair iron 1 configured in this manner, acidic water or alkaline water is generated and sprayed onto the hair H, and the hair H is straightened using the heated hair clamping surfaces (first hair clamping surface 1131 and second hair clamping surface 1231), thereby thermally setting the hair H.

[0044] Specifically, when the operation switch 14 is operated to turn on the power, the liquid delivery pump (liquid delivery unit) 24 is driven by the control device 30. When the liquid delivery pump (liquid delivery unit) 24 is driven by the control device 30, the NaCl aqueous solution (aqueous solution in which NaCl as an electrolyte is dissolved) stored in the storage unit 22 is supplied to the ion exchange unit 251 serving as the liquid generation unit 25.

[0045] At this time, if the ion exchange unit 251 is provided with a cation exchange unit 2511 having a cation exchange resin regenerated to H type, the internal cation exchange resin is replaced with H type and is strongly acidic, so that NaCl in the NaCl aqueous solution is ＋ and H bound to the cation exchange resin ＋ The ion exchange lowers the pH of the liquid, producing acidic water.

[0046] The acidic water produced in the ion exchange unit 251 is then sprayed from the outlet 21 toward the hair H. At this time, it is preferable that the acidic water is sprayed toward the ends of the hair H clamped between the first hair clamping surface 1131 and the second hair clamping surface 1231. In this way, when the hair iron 1 is pulled down toward the ends, the acidic water is applied to the hair H before it is clamped between the first hair clamping surface 1131 and the second hair clamping surface 1231. Therefore, when the hair H is clamped between the first hair clamping surface 1131 and the second hair clamping surface 1231 and treated, the ionic bonds of the hair H are broken by the acidic water, which makes it possible to further improve the treatment effect on the hair H, even for hair H with strong curls.

[0047] On the other hand, when the ion exchange unit 251 is provided with the anion exchange unit 2512 having an anion exchange resin regenerated to the OH type, the internal anion exchange resin is strongly basic due to substitution to the OH type, and therefore the Cl of the NaCl aqueous solution is － and OH bound to anion exchange resin － The ion exchange between the two raises the pH of the liquid, producing alkaline water.

[0048] Then, the alkaline water produced in the ion exchange unit 251 is sprayed from the outlet 21 toward the hair H. In this way, the hair H whose ionic bonds have been broken by the alkaline water is clamped between the first hair clamping surface 1131 and the second hair clamping surface 1231 and treated, so that even if the hair H is very curly, the treatment effect on the hair H can be further improved.

[0049] In this way, in this embodiment, when treating hair H using hair iron 1, acidic water or alkaline water is released toward hair H from outlet 21, and hair H can be treated with acidic water or alkaline water attached to hair H.

[0050] Then, by applying acidic water or alkaline water to the hair H, the acidic water or alkaline water breaks the ionic bonds of the amino acids in the hair H. When the ionic bonds of the amino acids in the hair H are broken in this way, the cuticle of the hair H opens, making it possible to make the hair H in a state in which it is easy to straighten its curls. In other words, it becomes possible to make the hair H in a state in which it is easy to treat it into a desired shape.

[0051] The hair H in this state can then be clamped by the hair clamping units (the first hair clamping unit 113 and the second hair clamping unit 123) heated by the heating unit, thereby more reliably shaping the hair H into the desired shape, even if the hair H is very curly.

[0052] Then, by clamping the hair H in this state with the hair clamping parts (first hair clamping part 113 and second hair clamping part 123) heated by the heating part and performing the treatment, it becomes possible to more reliably shape the hair H into the desired shape even if the hair H is very curly.

[0053] In this way, by using the hair iron 1 according to this embodiment, it is possible to further improve the treatment effect on the hair H.

[0054] Furthermore, by using the hair iron 1 described in this embodiment, it becomes possible to treat the hair H in a state where the ionic bonds have been broken in advance using acidic water or alkaline water. Therefore, even if the temperature of the hair clamping parts (first hair clamping part 113 and second hair clamping part 123) is set lower than usual, it becomes possible to further improve the treatment effect on the hair H. In this way, it becomes possible to treat the hair H with less thermal damage.

[0055] In this way, the hair iron 1 according to the present embodiment can further improve the treatment effect on the hair H while minimizing the thermal damage to the hair H caused by the treatment.

[0056] At this time, if alkaline water is applied to the hair H, the alkali can swell the cuticle layer, allowing the alkali to penetrate further into the hair H. As a result, the ionic bonds of amino acids are broken even inside the hair H, making it possible to further improve the treatment effect even for hair with strong curls.

[0057] Furthermore, if acidic water is applied to the hair H, the cations contained in the liquid such as raw water are ion-exchanged with the H ions in the ion exchange resin when the acidic water is produced, making it possible to remove the Ca ions contained in the liquid such as raw water. As a result, the adhesion of Ca to damaged parts of the hair H is suppressed, and the stiffness of the hair H can be further reduced.

[0058] Furthermore, in this embodiment, the storage section 22 is configured to store liquid, so that even when the hair iron 1 is used alone, acidic water or alkaline water can be applied to the hair H when treating the hair H. This makes it possible to apply acidic water or alkaline water to the hair H when treating the hair H, even when the hair iron 1 with liquid stored in the storage section 22 is carried and used alone while traveling, for example, and thereby makes it possible to further improve the usability of the hair iron 1.

[0059] In addition, in this embodiment, an electrolyte (salt) that does not contain Ca is used to increase the amount of ions dissolved in the raw water. This makes it possible to generate acidic water or alkaline water using a liquid with a small amount of dissolved Ca ions. In this way, when an OH-type ion exchange resin is used, CaCO 2 in an alkaline state can be generated. ３ It is possible to suppress the deposition of scale.

[0060] Furthermore, when an H-type ion exchange resin is used, Ca ions are removed (ion-exchanged with H ions) when acidic water is produced, making it possible to supply a liquid (acidic water) with less Ca to the hair H.

[0061] In this embodiment, as an example of a method for increasing the amount of ions dissolved in the raw water, a replenisher liquid prepared by supplementing tap water or the like with saline solution having a pre-adjusted concentration as an electrolyte is stored in the storage section 22. However, it is possible to increase the amount of ions dissolved in the raw water in various ways.

[0062] For example, the liquid discharge unit 20 may be provided with an electrolyte reservoir (electrolyte addition unit) 26 that is disposed upstream of the liquid generation unit 25 and that is capable of adding an electrolyte (salt) to the liquid. FIG. 5 is a diagram schematically illustrating a first modified example of the liquid discharge unit 20 according to the embodiment. Specifically, as shown in FIG. 5 , an electrolyte reservoir (electrolyte addition unit) 26 that stores an electrolyte (salt) may be disposed between the liquid delivery pump (liquid delivery unit) 24 and the liquid generation unit 25, and the liquid to which the electrolyte (salt) has been added may be supplied to the liquid generation unit 25 after passing through the electrolyte reservoir (electrolyte addition unit) 26.

[0063] FIG. 6 is a diagram schematically illustrating a second modified example of the liquid release unit 20 according to the embodiment. As shown in FIG. 6 , an inlet path 232 communicating with the electrolyte reservoir (electrolyte adding unit) 26 may be connected to the flow path 23 between the liquid feed pump (liquid feed unit) 24 and the liquid generating unit 25, and the electrolyte (salt) stored in the electrolyte reservoir (electrolyte adding unit) 26 may be introduced into the flow path 23 via the inlet path 232, thereby supplying the liquid to which the electrolyte (salt) has been added to the liquid generating unit 25. In this case, the introduction of the electrolyte (salt) into the flow path 23 may be performed continuously or intermittently. Such continuous or intermittent operation may be controlled, for example, by the control device 30.

[0064] In addition, when the generated acidic water or alkaline water is released from the release port (generated water release section) 21 toward the hair H, it is also possible to configure the device so that it is controlled so that the water is selected and released at an appropriate timing depending on the condition of the hair H.

[0065] The electrolyte added to the liquid is not limited to salt, and various electrolytes can be added to the liquid. For example, various electrolytes (neutral salt electrolytes) such as potassium chloride, sodium carbonate, sodium sulfate, and copper chloride can be added to the liquid. In this case, one type of electrolyte may be added to the liquid, or multiple types of electrolytes may be added to the liquid.

[0066] 7 is a diagram schematically illustrating a third modified example of the liquid discharging unit 20 according to the embodiment. As shown in Fig. 7, the liquid discharging unit 20 may include a water quality determining unit 28 that determines the hardness of the liquid introduced into the liquid generating unit 25, and an electrolyte reservoir (electrolyte adding unit) 26 that is arranged upstream of the liquid generating unit 25 and that can add an electrolyte to the liquid.

[0067] For example, a hardness sensor that measures the hardness of the liquid can be used as this water quality determination unit 28. Alternatively, the water quality determination unit 28 may be equipped with a hardness sensor and a hardness determination unit that determines whether the liquid introduced into the liquid generation unit 25 is soft water or hard water based on the hardness measured by the hardness sensor.

[0068] It is also possible to configure the system so that an appropriate method of adding electrolytes is controlled based on the result of the liquid hardness determination by the water quality determination unit 28. Such control can also be performed by the control device 30. For example, if the water quality determination unit 28 includes a hardness sensor and a hardness determination unit, it can control the addition of electrolytes in an appropriate manner based on the determination by the hardness determination unit (determination of whether the water is soft or hard). Such a hardness determination unit can be provided in the control device 30.

[0069] This allows a liquid of a more appropriate hardness to be introduced into the liquid generating section 25, making it possible to more reliably generate acidic water or alkaline water with a pH within the desired range (a pH appropriate for treating hair H).

[0070] Furthermore, as a method for controlling the appropriate supply of electrolyte by the control device 30, there is a method for adjusting the amount of electrolyte to be added based on the result of the liquid hardness determination by the water quality determination unit 28.

[0071] There is also a method of adjusting the type of electrolyte to be added based on the result of the liquid hardness determination by the water quality determination unit 28. In this case, it is possible to select and add one type of electrolyte, or to select and add multiple types of electrolytes mixed in an appropriate ratio.

[0072] The hair iron 1 may also be equipped with a hair condition detection unit that detects the condition of the hair H. The detection of the condition of the hair H by the hair condition detection unit can, for example, detect the pH of the hair surface using a pH sensor to collect information on deviation from a stable isoelectric point in advance. This detection can also be performed by a conventionally known method, such as image diagnosis using an imaging device such as a camera. The hair condition detection unit can also detect the strength of the curl of the hair H, such as the degree of curvature of the hair H, as the condition of the hair H.

[0073] It is also possible to configure the system so that the appropriate method of applying the electrolyte is controlled based on the detection result of the hair condition detection unit (the condition of the hair H). Such control can also be controlled by the control device 30.

[0074] As a method for controlling the appropriate application of electrolyte by the control device 30, there is a method for adjusting the amount of electrolyte to be added based on the detection result (condition of the hair H) of the hair condition detection unit.

[0075] There is also a method of adjusting the type of electrolyte to be added based on the detection result of the hair condition detection unit (the condition of the hair H). In this case, it is possible to select and add one type of electrolyte, or to select and add multiple types of electrolytes by mixing them in an appropriate ratio.

[0076] This also makes it possible to introduce a liquid of a more appropriate hardness into the liquid generating section 25, making it possible to more reliably generate acidic water or alkaline water with a pH within the desired range (a pH appropriate for treating hair H).

[0077] In addition, the hair iron 1 can be provided with a hair condition detection unit and an acidity / alkalinity control unit that controls the acidity of the acidic water or the alkalinity of the alkaline water based on the detection results of the hair condition detection unit (the condition of the hair H), so that acidic water with a more appropriate acidity or alkaline water with a more appropriate alkalinity is released onto the hair H.

[0078] It is also possible to use a liquid that does not require the addition of an electrolyte.

[0079] For example, it is possible to produce acidic water or alkaline water using hard water containing a large amount of hardness components such as Ca and Mg.

[0080] However, when alkaline water is produced using hard water containing a large amount of hardness components such as Ca and Mg, ３ Scale may be deposited, or Ca may adhere to damaged parts of the hair H.

[0081] 8 is a diagram schematically illustrating a fourth modified example of the liquid release unit 20 according to the embodiment. When using hard water containing a large amount of hardness components such as Ca and Mg, it is preferable to provide a hardness component removal unit 27 capable of removing hardness components from the liquid upstream of the liquid generation unit 25 in the flow path 23, as shown in FIG.

[0082] The hardness component removal section 27 can be formed using a cation exchange resin that has been regenerated into the Na type. That is, the hardness component removal section 27 can have a cation exchange resin that has been regenerated into the Na type.

[0083] In this way, when a liquid (hard water) such as tap water is passed through the hardness component removal section 27, the hardness components (e.g., Ca ions or Mg ions) contained in the liquid such as tap water are ion-exchanged with the Na ions in the ion exchange resin, thereby removing the hardness components (e.g., Ca ions or Mg ions). Therefore, even when hard water containing a large amount of hardness components is used, it is possible to prevent CaCO3 scale from being precipitated in an alkaline state and Ca from adhering to damaged parts of the hair H.

[0084] In this way, by using the hardness component removal section 27 having a cation exchange resin regenerated to the Na type, it is possible to remove hardness components (e.g., Ca ions or Mg ions) contained in water such as tap water while simplifying the configuration.

[0085] However, if the liquid, such as tap water, is high-hardness water containing a very large amount of hardness components, acidic water with an excessively low pH or alkaline water with an excessively high pH will be produced.

[0086] 9 is a diagram schematically illustrating a fifth modified example of the liquid release unit 20 according to the embodiment. When using high-hardness water containing a very large amount of hardness components, it is preferable that the flow path 23 includes a bypass flow path 233 that branches off from the main flow path 231 downstream of the hardness component removal unit 27, bypasses the liquid generation unit 25, and joins the main flow path 231 downstream of the liquid generation unit 25, as shown in FIG.

[0087] In this way, it is possible to dilute the acidic water or alkaline water by mixing the acidic water or alkaline water generated by passing through the liquid generating unit 25 with the liquid that has passed through the bypass flow path 233. Therefore, even when acidic water or alkaline water is generated using high-hardness water, it is possible to generate acidic water or alkaline water with a pH within the desired range (a pH appropriate for treating the hair H).

[0088] In this way, by providing the flow path 23 with the bypass flow path 233, even if the liquid, such as tap water, is high-hardness water with a very high content of hardness components, it is possible to produce acidic water or alkaline water with a desired pH range (a pH appropriate for treating the hair H). As a result, even when high-hardness water is used, the hair H is prevented from being subjected to an excessive load of acid or alkali, and heat damage to the hair H when treating it with the hair iron 1 can be minimized.

[0089] It is also possible to configure the hair iron 1 to release both acidic water and alkaline water onto the hair H when treating the hair H. Fig. 10 is a diagram schematically illustrating a sixth modified example of the liquid release unit 20 according to the embodiment.

[0090] For example, as shown in Fig. 10, the outlet 21 may include a first outlet 211 capable of releasing acidic water to the outside of the main body 10 and a second outlet 212 capable of releasing alkaline water to the outside of the main body 10. It is preferable that the first outlet 211 and the second outlet 212 are formed as far apart as possible on the main body 10 to prevent the acidic water and alkaline water sprayed from the respective outlets from mixing and being neutralized before adhering to the hair. Fig. 10 shows an example in which the first outlet 211 is provided on the tip side of the first hair clip 113 and the second outlet 212 is provided on the second gripping portion 122 side of the second hair clip 123.

[0091] The flow path 23 includes a first flow path 234 connected to the first discharge port 211 and a second flow path 235 connected to the second discharge port 212 .

[0092] This makes it possible to neutralize the acidic water and alkaline water remaining in the hair H after the hair H has been treated with acidic water or alkaline water, thereby preventing the hair H from remaining in an acidic or alkaline state, as occurs when the hair H is treated with only acidic water or alkaline water.

[0093] Therefore, as shown in Figure 10, if the hair H is treated using acidic water and alkaline water, after the treatment, the acidic water and alkaline water remaining in the hair H can be neutralized, returning the hair H to its normal state (a weakly acidic state which is the isoelectric point of healthy hair H), thereby providing the hair H with a so-called rinsing effect.

[0094] Fig. 11 is a diagram schematically illustrating a seventh modified example of the liquid releasing unit 20 according to the embodiment. In Fig. 10, the first flow path 234 and the second flow path 235 are independent flow paths, and acidic water and alkaline water are separately produced. However, as shown in Fig. 11, it is also possible to use a configuration in which the flow path 23 is branched midway and an electrolytic liquid producing unit 252 capable of producing both acidic water and alkaline water is disposed at the branched portion.

[0095] That is, the liquid generating unit 25 may include an electrolytic liquid generating unit 252 that electrolyzes a supplied liquid to generate an electrolytic liquid. The flow path 23 may include an inlet path 236 that communicates with the electrolytic liquid generating unit 252 on the upstream side of the electrolytic liquid generating unit 252, a first flow path 234 that communicates with the side of the electrolytic liquid generating unit 252 where acidic water is generated (acidic water discharge path 2521), and a second flow path 235 that communicates with the side of the electrolytic liquid generating unit 252 where alkaline water is generated (alkaline water discharge path 2522).

[0096] This makes it possible to reduce the number of parts of the liquid release section 20 capable of imparting a rinsing effect to the hair H, thereby making it possible to make the configuration of the liquid release section 20 capable of imparting a rinsing effect to the hair H simpler.

[0097] It is also possible to provide the main body 10 of the hair iron 1 with a liquid discharge section 20 having a plurality of paths, so that any of the paths can be selected.

[0098] For example, it is possible to configure the liquid discharging section 20 as shown in Fig. 12. Fig. 12 is a diagram schematically showing an eighth modified example of the liquid discharging section 20 according to the embodiment.

[0099] FIG. 12 shows an example in which any one of the routes shown in FIG. 4, the route shown in FIG. 8, and the route shown in FIG. 9 can be selected.

[0100] Specifically, an on-off valve 29 formed by an electromagnetic valve or the like is disposed at a branch point located downstream of the liquid delivery pump (liquid delivery section) 24 of the flow path 23. This on-off valve 29 is electrically connected to the control device 30 via wiring 40, and is controlled by the control device 30 so that only one of the paths is open.

[0101] An on-off valve 29 formed by a solenoid valve or the like is also disposed at a branch point on the upstream side of the bypass flow path 233. This on-off valve 29 is also electrically connected to the control device 30 via wiring 40, and is controlled by the control device 30 so that only one of the paths is open.

[0102] Furthermore, an on-off valve 29 formed by a solenoid valve or the like is also disposed at the junction located upstream of the discharge port 21. This on-off valve 29 is also electrically connected to the control device 30 via wiring 40, and is controlled by the control device 30 so that only one of the paths is open. This prevents the water from flowing into the other path.

[0103] The control device 30 controls the opening and closing of each on-off valve 29, thereby allowing the selection of one of the paths shown in Figure 4, Figure 8, and Figure 9. This path selection can be performed, for example, by operating a mode selection switch provided on the main body 10. It is also possible to provide a sensor in the storage unit 22, and have the control device 30 select the optimal path based on the measurement results of at least one of hardness and pH by the sensor.

[0104] In addition, in Figure 12, the liquid delivery pump (liquid delivery unit) 24 is also electrically connected to the control device 30 via wiring 40, and the drive of the liquid delivery pump (liquid delivery unit) 24 is controlled by this control device 30.

[0105] [Functions and Effects] The following describes the characteristic configurations of the hair irons shown in the above-described embodiment and the modifications thereof, and the effects obtained thereby.

[0106] (Technology 1) The hair iron 1 shown in the above embodiment and its modified examples includes a main body 10. The main body 10 has a heating unit (first heater 114 and second heater 124) and hair clamping units (first hair clamping unit 113 and second hair clamping unit 123) that can clamp hair H while heated by the heating unit.

[0107] Furthermore, the hair iron 1 has a liquid discharge part 20 provided in the main body 10, which has a discharge port 21 capable of discharging the acidic water or alkaline water to the outside of the main body 10.

[0108] When such a hair iron 1 is used to treat the hair H, the hair H can be treated with acidic water or alkaline water attached to the hair H.

[0109] In this way, by applying acidic water or alkaline water to the hair H, the acidic water or alkaline water breaks the ionic bonds of the amino acids in the hair H, opening the cuticle of the hair H, making it possible to make the hair H in a state in which it is easy to straighten its curls. In other words, it becomes possible to make the hair H in a state in which it is easy to treat it into a desired shape.

[0110] Then, by clamping the hair H in this state with the hair clamping parts (first hair clamping part 113 and second hair clamping part 123) heated by the heating part and performing the treatment, it becomes possible to more reliably shape the hair H into the desired shape even if the hair H is very curly.

[0111] In this way, by using the hair iron 1 shown in the above embodiment and its modified example, it is possible to further improve the treatment effect on the hair H.

[0112] Furthermore, by using the hair iron 1 described in the above embodiment and its modified examples, it becomes possible to treat the hair H in a state where the ionic bonds have been broken in advance using acidic water or alkaline water. Therefore, even if the temperature of the hair clamping parts (first hair clamping part 113 and second hair clamping part 123) is set lower than usual, it becomes possible to further improve the treatment effect on the hair H. In this way, it becomes possible to treat the hair H with less thermal damage.

[0113] In this way, the hair iron 1 shown in the above embodiment and its modified examples can further improve the treatment effect on the hair H while minimizing the thermal damage that the hair H receives during treatment.

[0114] (Technology 2) In the above (Technology 1), the liquid discharge unit 20 may include a storage unit 22 capable of storing liquid, and a flow path 23 that connects the storage unit 22 with the discharge port 21. Furthermore, the liquid discharge unit 20 may include a liquid delivery pump (liquid delivery unit) 24 that is provided in the flow path 23 and is capable of delivering the liquid in the storage unit 22 to the discharge port 21 side.

[0115] By configuring the hair iron 1 in this way and storing liquid in the storage section 22, even when using only the hair iron 1, it becomes possible to apply acidic water or alkaline water to the hair H when treating the hair H. In this way, even when the hair iron 1 with liquid stored in the storage section 22 is carried and used alone while traveling, for example, it becomes possible to apply acidic water or alkaline water to the hair H when treating the hair H, thereby further improving the usability of the hair iron 1.

[0116] (Technology 3) In the above (Technology 2), the liquid release section 20 may be provided in the flow path 23 and may include a liquid generation section 25 capable of generating at least one of acidic water and alkaline water.

[0117] With this configuration, simply storing tap water or the like in the storage unit 22 makes it possible to apply acidic water or alkaline water to the hair H when treating the hair H. That is, acidic water or alkaline water is generated in the liquid generating unit 25 using water such as tap water, and the generated acidic water or alkaline water can be applied to the hair H when treating the hair H with the hair iron 1. In this way, even when the hair iron 1 is carried alone and used at a destination such as a trip, it becomes possible to use water at the destination to apply acidic water or alkaline water to the hair H when treating the hair H, thereby further improving the usability of the hair iron 1.

[0118] (Technology 4) In the above (Technology 3), the liquid generating section 25 may include an ion exchange section 251 .

[0119] In this way, acidic water or alkaline water can be produced simply by passing tap water or other water through the ion exchange section 251, thereby simplifying the configuration and making it easier to produce acidic water or alkaline water using tap water or other water.

[0120] (Technology 5) In the above (Technology 4), the ion exchange section 251 may include a cation exchange section 2511 having a cation exchange resin regenerated to H-type.

[0121] In this way, when water such as tap water is passed through cation exchange unit 2511, cations contained in the water such as tap water are exchanged with H ions in the ion exchange resin to produce acidic water. Therefore, if ion exchange unit 251 is provided with cation exchange unit 2511, acidic water can be produced simply by passing water such as tap water through cation exchange unit 2511, making it possible to more easily produce acidic water using water such as tap water while simplifying the configuration.

[0122] Furthermore, if the cations contained in tap water or other water are ion-exchanged with the H ions in the ion exchange resin, it becomes possible to remove the Ca ions contained in tap water or other water, which in turn prevents Ca from adhering to damaged areas of the hair H, thereby further reducing the stiffness of the hair H.

[0123] Furthermore, if the ion exchange section 251 is provided with a cation exchange section 2511, it becomes possible to further improve the treatment effect even for hair with stronger curls.

[0124] (Technology 6) In the above (Technology 4) or (Technology 5), the ion exchange unit 251 may include an anion exchange unit 2512 having an anion exchange resin regenerated into the OH type.

[0125] In this way, when water such as tap water is passed through anion exchange unit 2512, alkaline water is produced by ion exchange between the anions contained in the water such as tap water and the OH ions in the ion exchange resin. Therefore, if ion exchange unit 251 is provided with anion exchange unit 2512, alkaline water can be produced simply by passing water such as tap water through anion exchange unit 2512, making it possible to more easily produce alkaline water using water such as tap water while simplifying the configuration.

[0126] Furthermore, if alkaline water is applied to the hair H, the alkali can swell the cuticle layer, allowing the alkali to penetrate further into the hair H. As a result, the ionic bonds of amino acids are broken even inside the hair H, making it possible to further improve the treatment effect even on hair with strong curls.

[0127] (Technology 7) In any of the above (Technology 3) to (Technology 6), a liquid to which an electrolyte has been added may be supplied to the liquid generating unit 25.

[0128] In this way, the amount of ion exchange can be adjusted using electrolytes, so even if the water, such as tap water, is soft water with a low hardness content, it is possible to produce acidic or alkaline water with a pH within the desired range (a pH appropriate for treating hair H).

[0129] In this way, by supplying a liquid with added electrolytes to the liquid generating unit 25 to generate acidic water or alkaline water, it becomes possible to supply the necessary amount of acidic or alkaline liquid to the hair H when treating the hair H with the hair iron 1, even when using tap water in a soft water area.

[0130] (Technology 8) In the above (Technology 7), the electrolyte may be table salt.

[0131] In this way, since the electrolyte does not contain Ca, it is possible to generate acidic water or alkaline water using a liquid with a small amount of Ca ions. Therefore, when an OH type ion exchange resin is used, CaCO 3 in an alkaline state is generated.３ It is possible to suppress the deposition of scale.

[0132] Furthermore, when an H-type ion exchange resin is used, Ca ions are removed (ion-exchanged with H ions) when acidic water is produced, making it possible to supply a liquid (acidic water) with less Ca to the hair H.

[0133] Furthermore, if salt is used as the electrolyte, it becomes possible to further improve the treatment effect even for hair with stronger curls.

[0134] (Technology 9) In the above (Technology 7) or (Technology 8), the liquid release unit 20 may include a water quality determination unit 28 that determines the hardness of the liquid introduced into the liquid generation unit 25, and an electrolyte storage unit (electrolyte addition unit) 26 that is arranged upstream of the liquid generation unit 25 and can add electrolyte to the liquid. The hair iron 1 may adjust the amount of electrolyte to be added based on the result of the liquid hardness determination by the water quality determination unit 28.

[0135] This allows a liquid of a more appropriate hardness to be introduced into the liquid generating section 25, making it possible to more reliably generate acidic water or alkaline water with a pH within the desired range (a pH appropriate for treating hair H).

[0136] (Technology 10) In addition, in any of the above-mentioned technologies (Technology 3) to (Technology 9), a hardness component removal section 27 capable of removing hardness components from the liquid may be provided upstream of the liquid generation section 25 of the flow path 23.

[0137] In this way, it is possible to supply the liquid from which ions such as Ca and Mg have been removed to the liquid generating unit 25. Therefore, even if hard water containing a large amount of hardness components is used, the liquid can be alkaline and contain CaCO ３ It is possible to suppress the deposition of scale.

[0138] (Technology 11) In the above (Technology 10), the hardness component removing section 27 may have a cation exchange resin regenerated into the Na type.

[0139] In this way, when water such as tap water is passed through the hardness component removal section 27, hardness components (e.g., Ca ions or Mg ions) contained in the water such as tap water are ion-exchanged with Na ions in the ion exchange resin, and the hardness components (e.g., Ca ions or Mg ions) are removed. Therefore, even if hard water containing a large amount of hardness components is used, the hardness components (e.g., CaCO ions) in an alkaline state are removed. ３ It is possible to suppress the deposition of scale.

[0140] In this way, by using the hardness component removal section 27 having a cation exchange resin regenerated to the Na type, it is possible to remove hardness components (e.g., Ca ions or Mg ions) contained in water such as tap water while simplifying the configuration.

[0141] (Technology 12) In the above (Technology 10) or (Technology 11), the flow path 23 may be provided with a bypass flow path 233 that branches off from the main flow path 231 downstream of the hardness component removal section 27, bypasses the liquid generation section 25, and joins the main flow path 231 downstream of the liquid generation section 25.

[0142] In this way, it is possible to dilute the acidic water or alkaline water by mixing the acidic water or alkaline water generated by passing through the liquid generating unit 25 with the liquid that has passed through the bypass flow path 233. Therefore, even when acidic water or alkaline water is generated using high-hardness water, it is possible to generate acidic water or alkaline water with a pH within the desired range (a pH appropriate for treating the hair H).

[0143] In this way, by providing the flow path 23 with the bypass flow path 233, even if water such as tap water is high-hardness water with a very high content of hardness components, it is possible to produce acidic water or alkaline water with a pH within the desired range (a pH appropriate for treating the hair H). As a result, even when high-hardness water is used, it is possible to prevent the hair H from being subjected to an excessive load of acid or alkali, and minimize heat damage to the hair H when treating the hair H with the hair iron 1.

[0144] (Technology 13) In any of the above-mentioned (Technology 3) to (Technology 12), the outlet 21 may include a first outlet 211 capable of releasing acidic water to the outside of the main body 10, and a second outlet 212 capable of releasing alkaline water to the outside of the main body 10. The flow path 23 may include a first flow path 234 connected to the first outlet 211, and a second flow path 235 connected to the second outlet 212.

[0145] In this way, after treating the hair H with acidic water or alkaline water, it is possible to neutralize the acidic water and alkaline water remaining in the hair H, thereby preventing the hair H from remaining in an acidic or alkaline state, as would occur if the hair H were treated using only acidic water or alkaline water.

[0146] Therefore, if the hair H is treated using acidic water and alkaline water, the acidic water and alkaline water remaining in the hair H can be neutralized after the treatment, returning the hair H to its normal state (a weakly acidic state which is the isoelectric point of healthy hair H), thereby providing the hair H with a so-called rinsing effect.

[0147] (Technology 14) In the above (Technology 13), the liquid generator 25 may include an electrolytic liquid generator 252 that electrolyzes a supplied liquid to generate an electrolytic liquid. The flow path 23 may include an inlet path 236 that communicates with the electrolytic liquid generator 252 upstream of the electrolytic liquid generator 252, a first flow path 234 that communicates with the side of the electrolytic liquid generator 252 where acidic water is generated (acidic water outlet path 2521), and a second flow path 235 that communicates with the side of the electrolytic liquid generator 252 where alkaline water is generated (alkaline water outlet path 2522).

[0148] This makes it possible to reduce the number of parts of the liquid release section 20 capable of imparting a rinsing effect to the hair H, thereby making it possible to make the configuration of the liquid release section 20 capable of imparting a rinsing effect to the hair H simpler.

[0149] [Others] The hair iron according to the present disclosure has been described above, but it is obvious to those skilled in the art that it is not limited to these descriptions and that various modifications and improvements are possible.

[0150] For example, the present disclosure can be applied to embodiments in which the configurations shown in the above-described embodiments and their modifications are modified, replaced, added, omitted, etc. Furthermore, it is also possible to combine the components described in the above-described embodiments and their modifications to create new embodiments.

[0151] In addition, when the liquid generating unit 25 generates acidic water and alkaline water, and the generated acidic water or alkaline water is released from the release port (generated water release unit) 21 toward the hair H, it is possible to control the release so that each is selected and released at an appropriate timing depending on the condition of the hair H.

[0152] In this way, for example, a treatment performed by releasing acidic water with too low a pH or alkaline water with too high a pH onto the hair H can be performed while appropriately diluting it with alkaline water or acidic water. That is, when a treatment is performed by releasing acidic water with too low a pH onto the hair H, it can be controlled so that it is appropriately diluted with alkaline water, and when a treatment is performed by releasing alkaline water with too high a pH onto the hair H, it can be controlled so that it is appropriately diluted with acidic water. In this way, it becomes possible to prevent the hair H from being subjected to more stress than necessary due to acid or alkali, while further improving the treatment effect on strongly curled hair H.

[0153] It is also possible to configure the system so that the supply state of alkali or acid supplied to the hair H is detected by a sensor or the like, and if an excess is being supplied, the system is controlled so that it is appropriately diluted with the opposite liquid (acidic water if an excess of alkali is being supplied, or alkaline water if an excess of acid is being supplied).

[0154] The present disclosure can also be applied to various types of hair irons.

[0155] For example, the present disclosure can be applied to hair irons 1 as shown in Fig. 13 and Fig. 14. Fig. 13 is a diagram showing another example of the hair iron 1 according to the embodiment, and is a diagram showing a schematic view of the hair iron 1 in a closed state. Fig. 14 is a diagram showing another example of the hair iron 1 according to the embodiment, and is a diagram showing a schematic view of the hair iron 1 in an open state.

[0156] In the hair iron 1 shown in Figures 13 and 14, a power supply unit 15 having an operator such as a power switch button 16 on the side is provided near the hinge portion 13, i.e., on the side of the gripping portions (first gripping portion 112 and second gripping portion 122) of the first arm portion 11 and the second arm portion 12.

[0157] The power supply unit 15 is housed in a partially exposed state inside the housing (first housing 111 and second housing 121). When the hair iron 1 is in a closed state, the power switch button 16 and other controls are entirely covered by the housing (first housing 111 and second housing 121) in a side view. On the other hand, when the hair iron 1 is in an open state, the power switch button 16 and other controls are exposed from the housing (first housing 111 and second housing 121).

[0158] The hair iron 1 is also provided with a locking section 17, which can be operated to hold the first arm section 11 and the second arm section 12 in a closed state.

[0159] In this way, the operator cannot be operated while the first arm section 11 and the second arm section 12 are closed, but the operator can be operated by releasing the lock by the lock section 17 and setting them in an open state.

[0160] With this configuration, for example, when the hair iron 1 is stored or carried in a bag or the like, the first arm 11 and the second arm 12 can be prevented from opening. Furthermore, since the controls cannot be operated when the first arm 11 and the second arm 12 are closed, accidental operation of the controls while the hair iron 1 is stored can be prevented. In other words, it is possible to more reliably prevent the power from being turned on unintentionally.

[0161] This configuration is particularly effective when the hair iron 1 is a cordless type.

[0162] 13 and 14 illustrate an example in which, when the hair iron 1 is in the closed state, the entirety of the controls, such as the power switch button 16, is covered by the housing (the first housing 111 and the second housing 121) in a side view. However, it is sufficient that the controls, such as the power switch button 16, cannot be operated when the hair iron 1 is in the closed state. For example, it is also possible to configure the controls so that a portion of the controls is exposed from the housing (the first housing 111 and the second housing 121) in a side view.

[0163] In addition, it is possible to configure the hair iron 1 so that it can be operated simply by closing it, but that it cannot be operated when it is locked by the locking section 17.

[0164] In addition, in the above embodiment and its modified example, a hair iron 1 in which the grip portion is divided into a first grip portion 112 and a second grip portion 122 is exemplified, but it is also possible to make a hair iron in which a first hair clamp portion 113 and a second hair clamp portion 123 are connected to one end of an undivided grip portion.

[0165] Furthermore, in the above embodiment and its modified example, the liquid release section 20 including the liquid generation section 25 has been exemplified, but it is also possible to configure the liquid release section without including the liquid generation section 25 .

[0166] For example, it is possible to store pre-generated acidic water or alkaline water in the storage section 22, and by driving the liquid delivery pump (liquid delivery section) 24, the acidic water or alkaline water stored in the storage section 22 is released through the flow path 23 and from the release port 21 toward the hair H.

[0167] It is also possible to use a commercially available alkaline water generator or the like, and connect the alkaline water discharge path or acidic water discharge path provided in the commercially available alkaline water generator or the like to the flow path 23 using an adapter or the like, so that the acidic water or alkaline water generated by the commercially available alkaline water generator or the like is released toward the hair H from the release port 21.

[0168] In addition, the specifications of the hair clamping portion, gripping portion, and other details (shape, size, layout, etc.) can also be changed as appropriate.

[0169] As described above, the hair iron of the present disclosure can minimize the heat damage to hair during treatment while further improving the hair treatment effect, and can be used in various hair irons, including those for home and commercial use.
