[0030] like Figure 1 and Figure 2 As shown in the figure, a hair straightener 1 provided in this embodiment of the present invention is mainly used for heat treatment of hair, so that the hair can be straightened after treatment. The hair straightener 1 includes a housing 11, a hair treatment component 12, and a heat insulation component 13. The housing 11 has an internal receiving space 110. The hair treatment component 12 can generate heat after being powered on, for heat treatment during the hair shaping process, thereby improving the effect of the hair shaping treatment. The hair treatment component 12 is disposed in the receiving space 110, and at least two are arranged opposite each other. The hair to be treated is placed between two hair treatment components 12, so that the hair is clamped and heated by the two hair treatment components 12, so that the hair can be heated evenly, thereby improving the effect of the hair shaping treatment.

[0031] Specifically, since both hair processing components 12 generate heat when powered on, this heat can be transferred to the housing 11 during use, especially for extended periods, causing the housing 11 to heat up and affecting the user's grip. Therefore, in this embodiment, a heat insulation component 13 is placed between the housing 11 and the hair processing components 12. This heat insulation component 13 at least blocks the transfer of heat from the hair processing components 12 to the housing 11. That is, the heat generated by the hair processing components 12 is not directly transferred to the housing 11 by the heat insulation component 13; instead, it is blocked by the heat insulation component 13, requiring the heat generated by the hair processing components 12 to be transferred to the heat insulation component 13 before it can be transferred to the housing 11. This reduces the temperature of the housing 11, effectively preventing high temperatures on the housing 11 from affecting the user's grip or causing safety hazards due to excessively high temperatures. The heat insulation element 13 effectively blocks the possibility of heat transfer to the housing 11, which improves the comfort and safety of using the hair straightener 1.

[0032] Optionally, to improve the heat insulation effect of the heat insulation component 13, the heat insulation component 13 can be made of a material with low thermal conductivity, thereby reliably achieving the heat insulation effect. Moreover, the heat insulation component 13 also serves as the overall outer shell of the hair straightener 1, thereby improving the overall structural strength of the hair straightener 1 and enhancing the product quality of the hair straightener 1.

[0033] Specifically, the heat insulation component 13 is disposed between the hair processing assembly 12 and the housing 11. The heat insulation component 13 can be connected to the housing 11, while the hair processing assembly 12 can be connected to the housing 11 and / or the heat insulation component 13, offering good assembly flexibility. With this configuration, the housing 11 serves as the main mounting support component, providing support for the overall structure, achieving assembly and fixation of the overall structure, resulting in structural stability and high reliability.

[0034] A hair straightener 1 provided in this embodiment of the invention includes a housing 11, a hair processing component 12, and a heat insulation component 13. The housing 11 has an internal receiving space 110, within which the hair processing component 12 is disposed, with at least two components arranged opposite each other, thereby enabling the clamping of hair for heat treatment. The heat insulation component 13 is positioned between the housing 11 and the hair processing component 12 to prevent heat generated by the hair processing component 12 from being transferred to the housing 11. Thus, the heat insulation component 13 effectively prevents heat transfer to the housing 11, preventing the housing 11 from overheating and thus avoiding situations where the housing 11 becomes too hot to hold or poses a safety hazard. The heat insulation component 13 prevents the housing 11 from becoming too hot, improving safety during use.

[0035] In some embodiments, such as Figure 2 As shown, the hair processing component 12 is positioned closer to or further away from the heat insulation component 13. That is, the hair processing component 12 is movable and can move relative to the heat insulation component 13, allowing the two opposing hair processing components 12 to move closer or further away. When the two hair processing components 12 are relatively far apart, a space is formed to accommodate the hair to be processed, allowing the hair to be inserted between the two hair processing components 12. When the two hair processing components 12 are relatively close, the inserted hair can be clamped, thereby achieving heat treatment of the clamped hair. In this embodiment of the invention, the hair processing component 12 is movable, resulting in a heat insulation gap 14 between the hair processing component 12 and the heat insulation component 13. That is, there is a gap between the heat insulation component 13 and the hair processing component 12, and they are not in complete direct contact. In this way, the heat on the hair processing component 12 is mainly transferred to the heat insulation component 13 through the air, which further reduces the rate of heating of the heat insulation component 13, thereby reducing the efficiency and total amount of heat transfer to the housing 11, effectively preventing the temperature on the housing 11 from becoming too high.

[0036] The hair straightener 1 provided in this embodiment of the invention employs a heat insulation component 13, with a heat insulation gap 14 formed between the hair processing component 12 and the heat insulation component 13. Thus, the hair straightener 1 has heat insulation from both the heat insulation component 13 and the heat insulation gap 14. This ingenious double heat insulation design prevents the temperature on the shell 11 of the hair straightener 1 from becoming excessively high, improving both user comfort and safety.

[0037] In some embodiments, such as Figure 2 As shown, the heat insulation component 13 at least covers the side of the hair processing component 12 facing the housing 11. With this configuration, the side of the hair processing component 12 facing the housing 11 is covered by the heat insulation component 13, so that the hair processing component 12 does not directly contact the housing 11, and thus the heat on the hair processing component 12 is not directly transferred to the housing 11, thereby improving the effect of the heat insulation component 13 in blocking temperature transfer.

[0038] In some embodiments, such as Figure 2As shown, the hair treatment assembly 12 includes a heating element 121 and a fixing shell 122. The heating element 121 is used for shaping and heat treatment of the hair. The fixing shell 122 is movably connected to the heat insulation element 13 and can move relative to the heat insulation element 13. The heating element 121 is mounted on the fixing shell 122. Specifically, the heating element 121 is an object that can generate heat when energized, such as an electric heating element, electric heating wire, or electric heating plate, and is shaped according to design requirements. The heating element 121 is mounted on the fixing shell 122, which provides support for the mounting position of the heating element 121. When the heating element 121 is energized, it heats up and comes into direct contact with the hair for heat treatment. In this embodiment of the invention, the fixing shell 122 is positioned between the heating element 121 and the heat insulation element 13, so that the heat generated by the heating element 121 can be directly transferred to the heat insulation element 13 through the fixing shell 122. Furthermore, the fixed shell 122 and the heat insulation component 13 are spaced apart to form a heat insulation gap 14. That is, the fixed shell 122 and the heat insulation component 13 are not in direct contact, but there is a gap. In this way, the heat on the fixed shell 122 needs to be conducted through the air between the heat insulation gaps 14. Since air has low heat conduction efficiency, the efficiency of heat transfer to the heat insulation component 13 is reduced, which further reduces the efficiency of the shell 11 heating up, thereby improving the comfort and safety of the user when holding the shell 11.

[0039] In some embodiments, such as Figure 2 As shown, a guide structure 15 is provided between the heat insulation member 13 and the fixed shell 122 to guide the movement of the fixed shell 122. Specifically, since the hair processing component 12 needs to be close to or far away from the heat insulation member 13, when they are close to each other, there should be a gap between the two hair processing components 12 to allow the hair to be processed to be inserted; and when they are far apart, the hair to be processed can be clamped between the two hair processing components 12 for heat treatment. Therefore, the guide structure 15 is provided to guide the movement of the fixed shell 122 relative to the heat insulation member 13, so that the fixed shell 122 can move smoothly and steadily, thereby improving the reliability of the hair insertion or clamping heating function. The guide structure 15 can be a matching structure that allows the heat insulation member 13 and the fixed shell 122 to cooperate with each other and provide guidance and limitation for the relative movement between them, providing a more reliable guarantee for the smooth movement of the hair processing component 12 within the shell 11.

[0040] In some embodiments, such as Figure 2As shown, the guide structure 15 is configured to include a guide post 151 and a guide hole. The guide post 151 is disposed on either the heat insulation member 13 or the fixed shell 122, and the guide hole 152 is disposed on the other one of the heat insulation member 13 and the fixed shell 122. The guide post 151 is movably inserted into the guide hole 152. In this way, the guide post 151 can provide guidance in the direction of movement. By inserting the guide post 151 into the guide hole 152, and through the mutual cooperation between the guide hole 152 and the guide post 151, the fixed shell 122 can move along the extension direction of the guide post 151, thereby achieving guidance and limitation of the movement direction of the fixed shell 122. This configuration has a simple overall structure and good guiding effect.

[0041] In some embodiments, such as Figure 2 As shown, the hair straightener 1 also includes an elastic element 16, which is connected to at least one hair processing component 12. The elastic element 16 drives the connected hair processing component 12 to move closer to or further away from the other hair processing component 12. The elastic element 16 is disposed between the heat insulation component 13 and the hair processing component 12, and is connected to the heat insulation component 13 and / or the hair processing component 12. Thus, the elastic element 16 generates a driving force, enabling the hair processing component 12 to move within the housing 11. Specifically, the two opposing hair processing components 12 normally remain relatively close or have a certain gap. After hair is inserted between the two hair processing components 12, the hair compresses the two hair processing components 12, causing them to move relatively away, thereby compressing the elastic element 16. Consequently, the restoring force generated by the elastic element 16 pushes the connected hair processing component 12 to compress the hair, allowing the hair to be clamped and effectively heated. The elastic element 16 can not only automatically adjust the distance between the two hair processing components 12 to accommodate different amounts of hair without manual adjustment, but also drive the hair processing components 12 to always keep in close contact with the hair, thus achieving reliable heat treatment of the hair.

[0042] In some embodiments, such as Figure 2 As shown, each hair processing component 12 is connected to at least two elastic elements 16, which are spaced apart. This arrangement ensures that each hair processing component 12 has at least two elastic elements 163 providing driving force. The relatively large driving force allows the hair processing component 12 to move reliably and remain relatively close, thereby achieving reliable hair clamping. Specifically, the multiple elastic elements 163 connected to each hair processing component 12 can be evenly spaced to ensure balanced force distribution on the hair processing component 12, thereby improving the smoothness and stability of its movement.

[0043] Specifically, the elastic element 16 can be a spring or a sheet, which can undergo elastic deformation under the action of external force and generate driving force through its own elastic deformation. It has a simple structure and can reliably drive the connected hair processing component 12 to move.

[0044] In some embodiments, such as Figure 2 and Figure 3 As shown, the hair to be processed is typically inserted through the open ends of the two hair processing components 12. Therefore, an anti-pinch gap 17 is provided at least between the fixing shell 122 and the heating element 121 at the end for inserting the hair to prevent hair from getting stuck. That is, the fixing shell 122 and the heating element 121 at the open end are spaced apart, so that even if hair enters the anti-pinch gap 17, the width of the anti-pinch gap 17 is greater than the thickness of the hair, allowing the hair to move freely within the anti-pinch gap 17, thus preventing the hair from getting stuck. In other words, during use, hair that enters the anti-pinch gap 17 can smoothly detach from it without getting stuck, effectively avoiding the pulling pain caused by stuck hair and improving the user's actual comfort.

[0045] In some embodiments, two heating elements 121 may be used to abut against each other at the ends into which the hair is inserted. In this way, after the hair is inserted between the two heating elements 121, the hair can be heated from two opposite sides by the two heating elements 121, so that the hair can be heated evenly and the heating efficiency of the hair can be improved, thereby improving the effect of heating the hair.

[0046] Specifically, the width of the anti-pinch gap 17 can be reasonably designed according to the diameter of a typical hair. In this embodiment of the invention, the width of the anti-pinch gap 17 is set to a range of 0.3mm to 0.6mm. For example, it can be 0.3mm, 0.4mm, 0.45mm, 0.5mm, or 0.6mm. It can also be any other value within the range of 0.3mm to 0.6mm. Thus, the width of the anti-pinch gap 17 is several times larger than the diameter of a hair, thereby not only reliably preventing hair from being pinched, but also effectively avoiding affecting the aesthetics of the product due to an excessively large gap size, ensuring the integrity of the product's appearance and guaranteeing its quality.

[0047] The hair straightener 1 provided in this embodiment of the invention employs a heat insulation member 13 disposed between the housing 11 and the hair processing component 12. This heat insulation member 13 reduces the transfer of heat generated by the hair processing component 12 to the housing 11, thereby effectively preventing the temperature of the housing 11 from rising. Furthermore, the fixing shell 122 and the heat insulation member 13 are spaced apart to form a heat insulation gap 14. This forces heat from the fixing shell 122 to be conducted through the air between the heat insulation gaps 14. Since air has low thermal conductivity, this reduces the efficiency of heat transfer to the heat insulation member 13, further reducing the efficiency of the housing 11 heating up. Thus, it effectively avoids situations where the temperature of the housing 11 becomes too high, making it inconvenient to hold the housing 11 directly or causing safety hazards due to excessively high housing temperature, thereby improving safety during use.

[0048] like Figure 4 As shown, this embodiment of the present invention also provides a hair straightener 2, including a body 21 and a hair straightener head 1 as described in any of the above embodiments, the hair straightener head 1 being connected to the body 21. The body 21 can be configured to be held and used by hand, and mainly contains an operable control circuit board, buttons, and power supply components. The hair straightener head 1 is connected to the body 21, thereby enabling control such as power on / off switching, and thus control of the heating function switch. The hair straightener head 1 has two opposing hair processing components 12 inside, which can heat up after being powered on to achieve heat treatment of the hair. By incorporating a heat insulation component 13, the hair straightener head 1 can effectively prevent the heat generated by the hair processing components 12 from being transmitted to the housing 11, thereby effectively avoiding the problems of the housing 11 being too hot to hold or causing safety hazards. Furthermore, the two opposing hair-handling components 12 can automatically adjust the space for clamping the hair and automatically maintain the clamped state, so that once the hair is inserted into the straightener head 1, no manual clamping force is required. Therefore, the hair straightener 2, using the aforementioned straightener head 1, is comfortable to use, safe and reliable, and provides good stability in straightening the hair. The straightening operation is simple, improving the ease of use of the hair straightener 2.

[0049] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
