Description

[Technical field]

[0001] The present disclosure relates to a heating element that can be inserted into and removed from a hair rod used for perming, and a cap used for the heating element. [Background technology]

[0002] Among perms, hot perms are generally performed using a dedicated hair rod with an integrated heating element, and are carried out in the following steps. (1) Wind moistened hair around a hair rod (winding). (2) Apply the chemical (first liquid) to the hair. (3) Heat the hair rod and keep it heated for a specified time. (4) Apply the chemical (second liquid) to the hair. (5) Leave it for a specified time. (6) Remove the hair rod from the hair (rod off). (7) Rinse the hair with water to wash away the second liquid. (8) Dry the hair.

[0003] In this case, there was a problem that the weight of the hair rod placed a heavy burden on the person being treated from winding to rod off. In response to the above problem, Patent Document 1 discloses an idea for a heating element that can be inserted into and removed from a commercially available hair rod used in hot perms. A typical commercially available hair rod is formed into a hollow cylinder. The heating element disclosed in Patent Document 1 can be removed from the hair rod when heating is not required during treatment, thereby reducing the burden on the person being treated due to its weight. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Publication No. 3194018 Summary of the Invention [Problem to be solved by the invention]

[0005] Incidentally, in perm treatment, the strength of the perm is adjusted according to the part of the head and the part of the hair, etc. Also, the ease with which a perm can be applied varies depending on the hair quality of each individual.

[0006] For these reasons, hair rods of various sizes are used in perm treatments. Specifically, the size (specifically, diameter) of the hair rod is selected in order to adjust the strength of the perm or according to how easily (or how difficult) the perm will be applied to each individual's hair type.

[0007] Here, when performing a treatment using a commercially available general hair rod and a heating element that can be inserted into and removed from the hair rod as described above, it is necessary to select a compatible combination.

[0008] In one aspect of the present disclosure, when performing a treatment using a commercially available general hair rod and a heating element that can be inserted into and removed from the hair rod, it is preferable to be able to easily and quickly identify and use the heating element that corresponds to a selected specific hair rod. [Means for solving the problem]

[0009] The heating element of the present disclosure is used together with a hair rod for perm and is configured to be freely inserted into the hair rod. The heating element has a cylindrical main body and a cap provided on at least one of both ends of the main body, the main body having an outer diameter corresponding to the inner diameter of the hair rod, and the cap having a color corresponding to the color of the hair rod.

[0010] According to the heating element of the present disclosure, the cap provided on at least one of the ends of the cylindrical main body of the heating element has a color corresponding to the color of the hair rod that can be used in combination with the heating element, so that the practitioner can easily and quickly identify the heating element that corresponds to a given hair rod. Specifically, the practitioner can visually identify the heating element according to the color. Therefore, the practitioner can easily and quickly select the heating element that is suitable for the hair rod to be used in the treatment, improving convenience.

[0011] In addition, the heating element of the present disclosure has an outer diameter corresponding to the inner diameter of the hair rod, and is therefore suitable for use in a set with the hair rod. For example, the heating element of the present disclosure is expected to be used in a set with a commercially available hair rod, and in this case, it is advantageous in terms of convenience and versatility.

[0012] The heating element of the present disclosure may have an outer diameter corresponding to an inner diameter of the main body such that when the heating element is inserted into the hair rod, the heating element is held within the hair rod by friction between the main body and the hair rod.

[0013] With such a heating element, the heating element is held in the hair rod by the friction between the main body and the hair rod, so there is no need to provide a special mechanism for holding the heating element, and it is easy to attach and detach, and in addition, it is easy to ensure a holding force that is strong enough for practical use. Therefore, it is highly convenient and versatile.

[0014] In the heating element of the present disclosure, the color of the cap may be approximately the same as the color of the hair rod. With such a heating element, the heating element that is suitable for the hair rod can be more easily identified by its color. If the colors are substantially the same, it can be more intuitively identified by visual inspection.

[0015] The technical idea of ​​the present disclosure may be a cap that can be attached to an end of a heating element that is used together with a hair rod for perm and is configured to be freely insertable into the hair rod, the cap having a color corresponding to the color of the hair rod. The cap may have substantially the same color as the hair rod.

[0016] Such a cap can provide the same effects as those described above. If the heating element of the present disclosure is used with a commercially available cylindrical hair rod, the hair wound around the hair rod can be heated via the hair rod.

[0017] By using the heating element of the present disclosure, a typical cylindrical hair rod available on the market can be used as a hair rod for hot perms. In this case, the heating element of the present disclosure is allowed to be inserted into the hair rod only when heating in step (3) among the above steps (1) to (8), and removed from the hair rod in the other steps. This can reduce the weight load (especially the load due to the weight of the heating element) on the patient during the perm treatment.

[0018] Moreover, the cap in the heating element of the present disclosure has a color corresponding to the hair rod (in other words, corresponding to the size of the hair rod). In this case, it is assumed that commercially available hair rods have different colors (specifically, colors) depending on the size of the hair rod, and the color of the cap may be a color corresponding to the color of the commercially available hair rod. A color corresponding to the color of the hair rod includes any color that a practitioner can recognize as corresponding, such as the same color, a similar color, a color in a complementary color relationship, the same pattern, or a similar pattern. Here, the term "color" may also include a pattern, a surface texture (texture of a material), and the like.

[0019] This allows the user to easily and quickly visually determine which heating element is compatible with a particular hair rod, which allows for quicker hair treatment and reduces the burden on the hair treatment practitioner and the person being treated.

[0020] Here, the material of the main body of the heating element of the present disclosure may be aluminum, titanium, or plastic. The main body may be configured to have both ends open, or only one end open. If both ends of the main body are open, the cap may be attached to both ends, and if only one end of the main body is open, the cap may be attached to only that end.

[0021] The heating element may have a thermostat, and the heating temperature of the heating element may be detected via the thermostat. The heating temperature of the heating element may also be controlled. For example, in one example, the heating temperature of the heating element may be set in the range of 60°C to 110°C. In this case, it is considered that the heating temperature is adjusted according to the treatment area, hair type, size of the hair rod, and the like. In adjusting the heating temperature, it may be possible to adjust it to any temperature within a predetermined range, or to any of a plurality of preset temperatures. In one example, four different set temperatures can be used. This allows the needs of the treatment to be met more precisely and accurately. [Brief description of the drawings]

[Diagram 3] Fig. 3A is a cross-sectional view of the heat generating element of this embodiment, and Fig. 3B is a view taken along the X arrow in Fig. 3A. [Figure 4] FIG. 2 is an explanatory diagram showing the perm process of the present embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Hereinafter, an embodiment of the present disclosure will be described with reference to the drawings. The heating element 1 of this embodiment shown in FIG. 1A is used by inserting it into and removing it from a hair rod 3 formed into a cylindrical shape as shown in FIG. 1B.

[0024] The heating element 1 includes a cylindrical main body 10 and caps 12A and 12B attached to both ends of the main body 10. As shown in FIG. 2B, the heating element 1 further includes a heater 16 provided inside the main body 10, and a cord 14 connected to the heater 16 and extending to the outside via the cap 12A.

[0025] The main body 10 is made of carbon fiber reinforced plastic. The reason why the main body 10 is made of carbon fiber reinforced plastic is that the main body 10 emits far infrared rays when heated by the heater 16. Other materials that emit far infrared rays when heated by the heater 16 may be aluminum, but are not limited to aluminum and carbon fiber reinforced plastic. Also, depending on the application, the material may not be one that emits far infrared rays when heated by the heater 16.

[0026] The cap 12A has a plug body 120A and a leg portion 122A standing upright from the plug body 120A. The cap 12B has a plug body 120B and a leg portion 122B standing upright from the plug body 120B.

[0027] When caps 12A, 12B are inserted into openings formed at both axial ends of body 10, leg portions 122A, 122B come into contact with the inner walls of body 10 to fix caps 12A, 12B to body 10. When caps 12A, 12B are attached to body 10 in this manner, body 10 and plug bodies 120A, 120B as a whole have an external appearance that appears as if both ends are formed with a diameter tapering outward relative to body 10.

[0028] The caps 12A, 12B have colors corresponding to the hair rod 3 (in other words, corresponding to the size of the hair rod 3). Specifically, there are heating elements 1 corresponding to the sizes of the hair rods 3 for each of a plurality of types (a plurality of sizes) of hair rods 3, and the caps 12A, 12B are colored so that the heating element 1 corresponding to a given hair rod 3 can be distinguished by the color of the cap 12A, 12B attached to that heating element 1.

[0029] For example, in one specific example, the caps 12A, 12B attached to the heating element 1 that matches the red hair rod 3 may be red (same color). In another example, the caps 12A, 12B attached to the heating element 1 that matches the checkered hair rod 3 may be checkered (same pattern) for a checkered hair rod 3. In addition, the colors may be similar or the same type of colors (warm colors, cool colors, etc.), complementary colors (colors that are opposite each other on the color wheel), the same type of patterns, or other colors that show a corresponding relationship. Here, the term "color" may also include patterns, surface textures (material textures), and the like.

[0030] The total length 1 of the heating element 1 may be standardized to 64.0 mm. The total length of the cap 12B may be standardized to 13.0 mm, while the total length of the cap 12A may vary depending on the type. The total length of the cap 12A may be 12.0 mm to 12.8 mm.

[0031] In cap 12B, the total length 12 of the part protruding from the end of heat generating element 1 may be unified to 8.0 mm. In the case of cap 12A having a cord port 4, the total length 11 of the part protruding from the end of heat generating element 1 may be 7.0 mm to 7.8 mm.

[0032] The caps 12A and 12B have different maximum diameters d depending on the type. The diameters of the caps 12A and 12B may be 8.5 mm to 21.2 mm. The cord 14 extends to the outside through a cord port 4 provided in one cap 12A of the two caps 12A, 12B.

[0033] A plug (not shown) is provided at the end of the cord 14, and the cord 14 can be connected to an external heat generation controller (not shown) via the plug. The heater 16 is not particularly limited and may be any heater suitable for perms, such as a sheet-shaped heater, a cylindrical heater, a rod-shaped heater, or a helical heater.

[0034] The steps for applying a perm using the heating element 1 and hair rod 3 described above will be described with reference to Fig. 4. Note that steps (1) to (8) are the same as the conventional steps for applying a perm, and steps (A) and (B) are steps when using the heating element 1 and hair rod 3 of the present disclosure.

[0035] (1) Winding: Wind damp hair around a hair rod. (A) Attaching the heating element: After washing the hair with water, the heating element 1 is attached to the hair rod 3. (2) Apply the first liquid to hair.

[0036] (3) Heating: The heating element 1 of the hair rod 3 is heated to heat the hair, and the hair is left for a predetermined period of time. (B) Removing the heating element: After being left to warm, the heating element 1 is removed from the hair rod 3.

[0037] (4) Apply the second liquid to the hair. (5) Leave it: Leave it for a specified period of time. (6) Rod off: The hair rod 3 is removed from the hair.

[0038] (7) Rinse with water: Rinse the hair with water. (8) Drying: Dry the hair. [Characteristic Effects of the Present Embodiment] Use of the heating element 1 described above provides the following characteristic functions and effects.

[0039] When the heating element 1 of this embodiment is inserted inside the hair rod 3, the heater 16 is located inside the hair rod 3, and by supplying power to the heater 16 via the cord 14, the hair rod 3 is heated.

[0040] Therefore, when the heating element 1 is used, a commercially available hair rod having a general cylindrical shape can be used as the hair rod 3 for perming. When using a conventional hair rod with a built-in heater, the person being treated must constantly feel the weight of the hair rod throughout steps (1) to (8). However, when using the heating element 1 of this embodiment, the person being treated only feels the weight of the hair rod 3 (more specifically, the weight of the heating element 1) when it is heated in step (3), so the person being treated is less likely to feel the weight associated with attaching the hair rod 3 to their head.

[0041] In addition, in the heating element 1 of this embodiment, the cord 14 extends directly from the outside to the heater 16 via the cap 12A, without going through a connector that is provided on the hair rod itself as in the conventional case, thereby eliminating failures such as corrosion and poor contact of the connector and reducing the risk of electric leakage or electric shock.

[0042] Furthermore, since the main body 10 is made of carbon fiber reinforced plastic, it emits far infrared rays when heated, which can improve the effectiveness of the perm treatment compared to a case where only the heater 16 is provided.

[0043] By using the caps 12A, 12B of this embodiment, it is possible to distinguish the hair rod 3 that corresponds (matches) the heating element 1 based on the color of the caps 12A, 12B, and it is possible to easily and quickly select the heating element 1 that corresponds to the hair rod 3 and insert it into the hair rod 3. This makes it possible to shorten the selection time that occurs during perm work, and to reduce the burden on both the patient and the practitioner (beautician).

[0044] By using a variety of sizes of heating elements 1 and hair rods 3, it is possible to apply a desired perm to each part of the hair. This allows us to provide a treatment service that is more tailored to the needs of the person being treated.

[0045] To explain this in more detail, when winding hair, a hair rod 3 of an appropriate size is selected and hair is wound around the hair rod 3. When heating the hair, it is necessary to attach a heating element 1 of a size that corresponds to the hair rod 3 used when winding the hair.

[0046] In the present application, by checking the colors of the caps 12A, 12B attached to the main body 10 of the heating element 1, the heating element 1 corresponding to each hair rod 3 can be easily and quickly selected.

[0047] Specifically, the caps 12A, 12B having the same color as the color of the hair rod 3 can be visually checked to select the heating element 1. Due to the color selection feature of the caps 12A, 12B, even when hair rods 3 of various sizes are used, a corresponding heating element 1 can be easily selected.

[0048] Since the caps 12A, 12B are removable from the main body 10, when necessary, the caps 12A, 12B can be removed from the main body 10, facilitating maintenance and cleaning of the caps 12A, 12B and the main body 10. If the caps 12A, 12B are damaged, only the caps 12A, 12B need to be replaced.

[0049] A thermostat for adjusting the heating temperature is used for the heating element 1 of this embodiment, and the power output can be adjusted to provide a perm that is more precisely and accurately tailored to the patient. By adjusting the amount of power supplied (in other words, the heating temperature) depending on the area being treated, the final finish of the perm can be adjusted.

[0050] This makes it possible to provide treatment services tailored to the needs of the person receiving the treatment. [Other embodiments] Although the embodiments have been described above, it goes without saying that the present disclosure is not limited to the above-described embodiments and can take various forms.

[0051] The heating element 1 described in the above embodiment is merely an example, and is not limited to this.

[0052] The heating element may have a sheet-like configuration. In such a case, the sheet-like heating element is rolled and inserted into the hair rod. The ends of the heating element (both ends of the heating element after rolling) may be configured to have a color corresponding to the hair rod, similar to the characteristics of the cap of the above embodiment. Also, the heating element may be formed in a cylindrical shape, and instead of being provided with a cap, both ends of the cylindrical heating element may be directly colored to correspond to the hair rod. In the above embodiment, the cylindrical hair rod 3 is used, but the hair rod 3 may be a cylinder having an elliptical or polygonal cross section. In this case, the heating element 1 may be configured so that its shape matches the shape of the hair rod 3.

[0053] In the above embodiment, an example has been described in which the main body 10 is formed from carbon fiber reinforced plastic, but plastics other than carbon fiber reinforced plastic may also be used.

[0054] As for materials other than carbon fiber reinforced plastic, since the heating element 1 of this embodiment is used in the head, a material having a specific gravity of 4.9 g / cm 3 The following lightweight materials are recommended:

[0055] The specific gravity of aluminum is 2.7g / cm 3 , the specific gravity of titanium is 4.51g / cm 3 The specific gravity of the plastic is 0.9g / cm for the lightweight polyethylene material. 3 , heavy fluororesin type, 2.2g / cm3 Therefore, the main body 10 may be formed from these materials.

[0056] The specific gravity of carbon fiber reinforced plastic is 1.7g / cm 3 It is. The specific gravity of iron is 7.8g / cm 3 , the specific gravity of stainless steel is 8.0g / cm 3 , the specific gravity of brass is 8.7g / cm 3 When a material with a high specific gravity is used, the weight can be reduced by reducing the thickness of the material.
