Description

Technical Field

[0001] This utility model relates to the field of hair care technology, and in particular to an electric heated comb. Background Technology

[0002] With people paying increasing attention to their personal image and hairstyle, electric hair styling tools have become indispensable hair care products in daily life. Among them, electric combs, as a tool that integrates combing, heating, and styling functions, are widely popular due to their ease of use and natural styling results.

[0003] The basic working principle of existing heated combs is as follows: a heating element (usually a metal-ceramic heater, PTC heating element, or heating wire) is placed inside the comb body. When the power is turned on, the heating element generates heat. To efficiently transfer heat to the hair, these heated combs typically use metal materials with excellent thermal conductivity (such as aluminum alloy or stainless steel) to manufacture the comb teeth. Heat is conducted from the internal heating element to the metal comb teeth, causing them to heat up rapidly. When the user combs their hair, the heated metal comb teeth heat the hair strands, thereby creating the desired curls or straight styles, significantly improving the styling ability of the hair.

[0004] However, this design using directly heated metal comb teeth has a significant technical drawback: metal itself is a good conductor of heat. After absorbing heat, the overall temperature of the comb teeth rises rapidly to a high level. High-temperature comb teeth can cause considerable damage to hair, easily leading to problems such as frizz and dryness.

[0005] Therefore, existing heated combs need to be improved to address the problem that they can easily damage hair due to excessively high comb temperatures.

[0006] The information disclosed in this background section is included only to enhance the understanding of the context of this disclosure, and therefore may contain information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0007] One objective of this invention is to provide an electric heating comb that effectively solves the problem that existing electric heating combs easily damage hair due to excessively high comb tooth temperatures.

[0008] To achieve the above objectives, this utility model provides an electric heating comb, comprising:

[0009] Hand-held comb body;

[0010] An electrically heated comb assembly, which is mounted on the handheld comb body, includes a metal inner core, a heating element located inside the metal inner core and in contact with the metal inner core for heat conduction, and an adhesive cover located outside the metal inner core and at least partially covering the outer surface of the metal inner core.

[0011] Optionally, the metal inner core includes a comb base that is in contact with the heating element on the inside, and a plurality of metal comb teeth fixed on the outside of the comb base.

[0012] Optionally, the adhesive cover is a continuous structure that completely covers the outer surface of all the metal comb teeth;

[0013] Alternatively, the adhesive cover may be provided only at the end of each metal comb tooth away from the comb tooth base.

[0014] Optionally, the electrothermal comb assembly further includes a limiting spring;

[0015] The limiting spring is located on the side of the heating element away from the metal core, and is used to elastically push the heating element toward the metal core;

[0016] The inner side of the comb base is provided with several spring clip fixing posts, which extend through the heating element and are fastened to the limiting spring clip.

[0017] Optionally, the handheld comb body includes:

[0018] Handheld casing;

[0019] A comb tooth mounting frame is mounted on the handheld housing, and the middle position of the comb tooth mounting frame is provided with a plurality of comb tooth mounting windows for mounting the electric heating comb tooth assembly.

[0020] Optionally, the comb mounting frame is snap-fitted to the handheld housing and / or secured with screws.

[0021] Optionally, the inner side of the comb base is further provided with several comb positioning posts;

[0022] The handheld housing is provided with a plurality of positioning post holes corresponding to each of the comb tooth positioning posts, and each of the comb tooth positioning posts is inserted into the corresponding positioning post hole.

[0023] Optionally, the edge of the comb mounting frame is provided with a plurality of non-heat-conducting comb teeth, and each of the non-heat-conducting comb teeth and the comb mounting frame is an integral injection-molded structure.

[0024] Optionally, each of the non-thermally conductive comb teeth is flush with each of the electrically heated comb tooth assemblies;

[0025] Alternatively, each of the non-thermally conductive comb teeth is higher than each of the electrically heated comb tooth assemblies;

[0026] Alternatively, each of the non-thermal comb teeth is lower than each of the electrically heated comb tooth assemblies.

[0027] Optionally, the cross-sectional dimensions of both the non-thermal-conducting comb teeth and the metal comb teeth gradually decrease from the inside out;

[0028] Furthermore, the ends of the non-thermal-conducting comb teeth are fixed with ball heads.

[0029] The beneficial effects of this utility model are as follows: It provides an electric heated comb where, when the comb is in operation, the heating element generates heat, which is conducted to the metal inner core in contact with it. Because the metal inner core is covered with a rubber cover, heat is transferred from the metal inner core to the rubber cover, which directly contacts the hair. The rubber cover is made of a rubber material (such as fluororubber or silicone), thereby reducing the surface temperature of the hair in direct contact and preventing hair damage due to high temperatures. This not only solves the problem of excessively high comb temperatures damaging hair in existing electric heated combs, but also provides a soft contact surface, further reducing mechanical damage to the hair.

[0030] Therefore, this utility model provides an electric heating comb that can effectively solve the problem that existing electric heating combs easily damage hair due to excessively high comb tooth temperature. Attached Figure Description

[0049] See Figures 1-3 This embodiment provides an electric heating comb, comprising:

[0050] Hand-held comb body 1;

[0051] The electrically heated comb assembly 2 is mounted on the handheld comb body 1 and includes a metal inner core 201, an electric heating element 202 located inside the metal inner core 201 and in contact with the metal inner core 201 for heat conduction, and an adhesive cover 203 located outside the metal inner core 201 and at least partially covering the outer surface of the metal inner core 201.

[0052] Optionally, the adhesive cover 203 is made of fluororubber or silicone.

[0053] When the heated comb is in operation, the heating element 202 generates heat, which is conducted to the metal inner core 201 in contact with it. Since the metal inner core 201 is covered by a rubber cover 203, heat is transferred from the metal inner core 201 to the rubber cover 203, which directly contacts the hair. The rubber cover 203 is made of a rubbery material (such as fluororubber or silicone), thereby reducing the surface temperature of the hair in direct contact and preventing hair damage due to high temperatures. This not only solves the problem of excessively high comb temperatures damaging hair in existing heated combs, but also provides a soft contact surface, further reducing mechanical damage to the hair.

[0054] Therefore, this utility model provides an electric heating comb that can effectively solve the problem that existing electric heating combs easily damage hair due to excessively high comb tooth temperature.

[0055] In this embodiment, the metal inner core 201 includes a comb base 2011 that is in contact with the heating element 202 on the inner side, and a plurality of metal comb teeth 2012 fixed on the outer side of the comb base 2011.

[0056] Optional, see Figures 2-4 In this embodiment, the adhesive cover 203 has a continuous structure, completely covering the outer surface of all the metal comb teeth 2012. This complete coverage design provides comprehensive heat insulation protection, ensuring that the temperature of the entire comb tooth surface is reduced, resulting in superior protection.

[0057] Or see Figure 6 In some other embodiments, the adhesive cover 203 is provided only at the end of each metal comb tooth 2012 away from the comb tooth base 2011, and the circumferential surface of the metal comb tooth 2012 is not covered and is exposed. This end-only covering design provides localized heat insulation for the hair root area, saving material.

[0058] Whether it's full coverage or end coverage, both methods can effectively reduce the temperature of the comb teeth and prevent high-temperature damage to the hair.

[0059] In this embodiment, the electrothermal comb assembly 2 further includes a limiting spring 204. The limiting spring 204 is located on the side of the heating element 202 away from the metal inner core 201, and is used to elastically push the heating element 202 towards the metal inner core 201. Specifically, the inner side of the comb base 2011 is provided with a plurality of spring fixing posts 2011a, which extend through the heating element 202 and are fastened to the limiting spring 204.

[0060] The limiting spring 204 elastically pushes against the heating element 202, ensuring that the heating element 202 always maintains close contact with the metal inner core 201, thereby ensuring efficient heat transfer from the heating element 202 to the metal inner core 201. The limiting spring 204 ensures close contact between the heating element 202 and the metal inner core 201, avoiding poor thermal conductivity and improving thermal efficiency; the elastic pushing allows for thermal expansion and contraction, maintaining stable contact pressure.

[0061] In this embodiment, the handheld comb body 1 includes:

[0062] Handheld casing 101;

[0063] A comb tooth mounting frame 102 is mounted on the handheld housing 101, and the comb tooth mounting frame 102 is provided with a plurality of comb tooth mounting windows 1021 for mounting the electric heating comb tooth assembly 2 at the middle position.

[0064] Optionally, the comb mounting frame 102 is snap-fitted to and / or screwed into the handheld housing 101. Specifically, the comb mounting frame 102 is provided with a slot 1022 for snap-fitting and fixing to the handheld housing 101 and / or a threaded hole 1023 for screwing into the handheld housing 101.

[0065] Simple snap-fit ​​connections facilitate quick assembly and disassembly, improving assembly and maintenance efficiency; while simple screw fastening provides higher connection reliability and stability. Furthermore, the two methods can be combined: initial positioning is achieved through snap-fit ​​connections, followed by complete fixation through screw fastening, resulting in a more robust product structure and a longer service life.

[0066] It should be noted that the handheld housing 101 has a control circuit board that is electrically connected to the heating element 202. The specific structure of the circuit board is existing technology and will not be described in detail in this embodiment.

[0067] Furthermore, the inner side of the comb base 2011 is provided with a plurality of comb positioning posts 2011b. The handheld housing 101 is provided with a plurality of positioning post insertion holes 1011 corresponding to each of the comb positioning posts 2011b, and each comb positioning post 2011b is inserted into the corresponding positioning post insertion hole 1011.

[0068] When installing the electric heating comb assembly 2, the comb positioning post 2011b inside the comb base 2011 will be precisely inserted into the corresponding positioning post insertion hole 1011 on the handheld housing 101. The cooperation between the comb positioning post 2011b and the positioning post insertion hole 1011 achieves precise positioning of the electric heating comb assembly 2 on the handheld housing 101, preventing it from shifting.

[0069] In this embodiment, the edge of the comb mounting frame 102 is provided with a plurality of non-heat-conducting comb teeth 103, and each of the non-heat-conducting comb teeth 103 and the comb mounting frame 102 is integrally injection molded. When combing hair, the electric heating comb tooth assembly 2 is responsible for heating and shaping, while the non-heat-conducting comb teeth 103 located on the edge of the comb mounting frame 102 assist in combing the hair and are not used for heat conduction. The presence of the non-heat-conducting comb teeth 103 can reduce the opportunity for direct contact between the hot comb teeth and the scalp, improve the comfort of use, and help to comb the hair more evenly.

[0070] Optionally, each of the non-heat-conducting comb teeth 103 is flush with each of the electric heating comb tooth assemblies 2; or, each of the non-heat-conducting comb teeth 103 is higher than each of the electric heating comb tooth assemblies 2; or, each of the non-heat-conducting comb teeth 103 is lower than each of the electric heating comb tooth assemblies 2.

[0071] The following is a detailed explanation of the specific working process and beneficial effects of these three types of high-level relationships:

[0072] 1. The non-heat-conducting comb teeth 103 are higher than the electrically heated comb tooth assembly 2.

[0073] During combing, the higher non-heat-conducting comb teeth 103 will first contact the scalp and hair roots, forming a safe gap to ensure that the heated comb teeth assembly 2 keeps a distance from the scalp and avoids direct contact.

[0074] The non-heat-conducting comb teeth 103 have a core function of safety protection that surpasses the electric heating comb teeth assembly 2. They can effectively prevent the high-temperature electric heating comb teeth assembly 2 from directly contacting the scalp, preventing burns. They are especially suitable for users with thin hair, sensitive scalps, or for combing and styling close to the scalp.

[0075] 2. The non-heat-conducting comb teeth 103 are flush with the electrically heated comb tooth assembly 2.

[0076] The ends of all the comb teeth (including the electrically heated comb tooth assembly 2 and the non-heat-conducting comb teeth 103) are on the same plane, simultaneously contacting and combing the hair. The heat is provided by the electrically heated comb tooth assembly 2, while the non-heat-conducting comb teeth 103 mainly serve a physical combing function.

[0077] The core function of the non-heat-conducting comb teeth 103 being flush with the electrically heated comb teeth assembly 2 is to evenly comb and heat the hair. This design is closest to the user experience of a traditional comb, providing uniform heating and physical support throughout the combing process, ensuring even heating of the hair and a naturally smooth style. It offers a basic and universal user experience.

[0078] 3. The non-heat-conducting comb teeth 103 are lower than the electrically heated comb tooth assembly 2.

[0079] During combing, the heated comb teeth 2 contact the hair before the non-heat-conducting comb teeth 103. Heat is preferentially applied to the hair, and the non-heat-conducting comb teeth 103 follow up, mainly serving to assist in combing and styling.

[0080] The core function of the non-heat-conducting comb teeth 103, which are lower than those of the heated comb teeth 2, is to enhance heating efficiency and styling ability. This design ensures that heat can be absorbed by the hair more directly and quickly, making it particularly suitable for localized styling that requires focused heating (such as creating volume at the roots or dealing with stubborn curls) or for styling coarser hair, thus improving styling efficiency.

[0081] Furthermore, the cross-sectional dimensions of both the non-heat-conducting comb teeth 103 and the metal comb teeth 2012 gradually decrease from the inside out; and the ends of the non-heat-conducting comb teeth 103 are fixed with ball heads. The gradual decrease in cross-sectional dimensions from the inside out not only facilitates insertion into the hair roots but also reduces the pulling sensation during combing. The ball head structure disperses the combing force, preventing sharp ends from scratching the scalp, significantly improving comfort and safety.

[0082] Finally, it should be noted that although the above embodiments have been described in the text and drawings of this application, this should not limit the scope of patent protection of this application. Any technical solutions that are based on the essential concept of this application and utilize the content described in the text and drawings of this application, resulting in equivalent structural or procedural substitutions or modifications, as well as the direct or indirect application of the technical solutions of the above embodiments to other related technical fields, are all included within the scope of patent protection of this application.
