Description

Technical Field

[0001] The utility model relates to a hair straightener. Background Art

[0002] As a commonly used hairdressing tool, hair straighteners can straighten hair by clamping hair and heating it with a heating element. However, in the traditional design of hair straighteners, the heating element is usually made of metal material, directly exposed to the outside, and directly in contact with the hair during use. Although this design can quickly transfer heat and straighten hair, it also has some significant disadvantages and problems.

[0003] First, the high temperature of the metal heating element directly contacts the hair, which can easily cause hair damage. High temperature will destroy the cuticle on the surface of the hair, making the hair dry and brittle, and even causing hair breakage and split ends. At the same time, long-term and frequent use of high-temperature hair straighteners will cause cumulative damage to the health of the hair, causing the hair to lose its luster and elasticity.

[0004] Secondly, the temperature distribution of the metal heating element is uneven, and local overheating is prone to occur during use. This not only affects the consistency of the straightening effect, but may also burn the hair or scalp due to overheating, posing certain safety hazards. Even if some high-end hair straighteners are equipped with temperature control functions, it is still difficult to completely solve the various problems caused by the direct contact of the metal heating element with the hair. Utility Model Content

[0005] The utility model aims to provide a hair straightener which can evenly conduct heat and prevent the metal heating element from directly contacting the hair, thereby effectively reducing the damage of high temperature to the hair.

[0006] The purpose of the utility model is achieved in this way:

[0007] A hair straightener, comprising a clamp and a heat-conducting cloth sleeve, the clamp comprising a first clamping part and a second clamping part, the end surface of the first clamping part facing the second clamping part is provided with a heating element, the end surface of the second clamping part facing the first clamping part is provided with a heating element, the first clamping part is provided with an annular groove at the periphery of the heating element, the shape of the heat-conducting cloth sleeve matches the shape of the heating element, the heat-conducting cloth sleeve is sleeved on the heating element, the heat-conducting cloth sleeve and the heating element are bonded together, and the lower edge of the heat-conducting cloth sleeve is inserted into the annular groove and clamped;

[0008] The second clamping portion is located on the periphery of the heating element and is provided with an annular groove. The shape of the thermal conductive cloth sleeve matches the shape of the heating element. The thermal conductive cloth sleeve is placed on the heating element. The thermal conductive cloth sleeve and the heating element are bonded together. At the same time, the outer edge of the thermal conductive cloth sleeve is inserted into the annular groove and clamped.

[0009] Uniform heat transfer: The heat-conductive cloth covers the heating element, which can evenly distribute heat, so that the hair is heated more evenly and avoids damage to the hair caused by local overheating.

[0010] Improved safety: The heat-conductive cloth sleeve provides an extra layer of protection, reducing the possibility of direct contact between the heating element and the hair, reducing the risk of burns and enhancing safety during use.

[0011] Enhanced clamping effect: The design of the annular groove ensures that the thermal conductive sleeve is firmly fixed and is not easy to slide or fall off, thereby ensuring the stability and reliability of the clamp during use.

[0012] The purpose of the utility model can also be solved by the following technical measures:

[0013] Furthermore, the heat-conducting cloth sleeve and the heating element are bonded together by a high-temperature resistant adhesive.

[0014] Enhanced bonding strength: The high temperature resistant adhesive can maintain good bonding performance in high temperature environment, ensuring that the bonding between the thermal conductive cloth cover and the heating element is more firm and not easy to fall off.

[0015] Excellent high temperature resistance: The high temperature resistant adhesive can withstand the high temperature generated when the hair straightener is working, avoiding the problem of ordinary glue failing at high temperature, thus ensuring the reliability and safety of the product.

[0016] Improve service life: Since the high temperature resistant adhesive can maintain a stable bonding effect even at high temperatures, this greatly extends the service life of the thermal conductive cloth sleeve and the heating element, reduces the replacement frequency, and reduces maintenance costs.

[0017] Maintain thermal conductivity: The high temperature resistant adhesive will not deform or decompose in a high temperature environment, ensuring close contact between the thermal conductive cover and the heating element, thereby maintaining good thermal conductivity and improving the use effect of the hair straightener.

[0018] Increased safety: Since the high temperature resistant adhesive has good bonding strength and heat resistance, the risk of debonding caused by high temperature is reduced, thereby increasing safety during use.

[0019] Furthermore, the thermally conductive cloth sleeve includes a thermally conductive cloth sleeve wall and an annular lower edge that match the surface shape of the heating element. The thermally conductive cloth sleeve wall is tightly attached to the surface of the heating element, and the thermally conductive cloth sleeve wall and the surface of the heating element are bonded together. The annular lower edge is tightly attached to the side wall of the heating element, and the annular lower edge and the side wall of the heating element are bonded together, and the annular lower edge is inserted into the annular groove.

[0020] Enhanced thermal conductivity: The wall of the heat-conducting cloth sleeve is close to the surface of the heating element, ensuring that heat is evenly transferred from the heating element to the heat-conducting cloth sleeve, thereby evenly heating the hair and improving the thermal conductivity of the hair straightener.

[0021] More stable structure: The annular bottom edge is not only bonded to the side wall of the heating element, but also inserted into the annular groove. The double fixing method greatly enhances the stability of the heat-conducting cloth sleeve and prevents it from shifting or falling off during use.

[0022] Uniform heating: The close contact between the wall of the heat-conducting cloth sleeve and the surface of the heating element and the multi-point bonding of the annular lower edge ensure that the heat-conducting cloth sleeve is heated evenly, avoiding damage to the hair caused by local overheating and improving safety of use.

[0023] Extended service life: The multi-point bonding and clamping design allows the heat-conducting cloth cover to remain firm at high temperatures and not easily damaged, thereby extending the service life of the hair straightener and reducing the frequency of replacement.

[0024] Improved safety: The design of the annular bottom edge inserted into the annular slot prevents the risk of the heat-conducting cloth sleeve falling off at high temperatures, enhances safety during use, and users can operate the hair straightener more confidently.

[0025] Furthermore, a metal plate is adhered to the inner wall of the annular lower edge.

[0026] Improve verticality and stability: The metal plate is pasted on the inner wall of the annular lower edge, which can significantly improve the verticality of the annular lower edge, making it more stable and less likely to deform when pasted on the side wall of the heating element, thereby ensuring close contact between the thermal conductive cloth sleeve and the heating element.

[0027] Enhanced fixing effect: The presence of the metal plate makes the annular bottom edge more solid, helps the annular bottom edge to be more conveniently inserted into the annular slot, and clamped and fixed to prevent the thermal conductive cloth sleeve from loosening or falling off during use.

[0028] Uniform heat transfer: The metal plate has good thermal conductivity, which can help the heat-conducting cloth cover to distribute the heat of the heating element more evenly, further improving the heating efficiency of the hair straightener, ensuring that the hair is heated evenly and reducing damage.

[0029] Easy installation and maintenance: Due to the support of the metal plate, the annular bottom edge is smoother when inserted into the annular slot, and the installation and removal process becomes easier, which is convenient for users to maintain and replace.

[0030] Improved safety: The solid annular bottom edge can better fix the heat-conducting cloth cover, avoiding the risk of displacement or falling off during use, further improving the safety of use, and users can operate the hair straightener more safely.

[0031] Furthermore, the heat-conducting cloth sleeve is a heat-conducting cloth sleeve made of glass fiber cloth coated with glue or a heat-conducting cloth sleeve made of Teflon cloth.

[0032] Glue coating on glass fiber cloth: Glass fiber cloth has extremely high heat resistance. After glue coating, its high temperature resistance can be further enhanced to ensure that the thermal conductive cloth sleeve will not be deformed or damaged in a high temperature working environment.

[0033] Glue-coated fiberglass cloth: Glue-coated fiberglass cloth has good thermal conductivity and can quickly transfer the heat of the heating element, ensuring uniform heating of the hair and improving the straightening effect.

[0034] Glue coating on glass fiber cloth: The glue-coated glass fiber cloth can remain stable in high temperature environment, reducing the risk of thermal conductive cloth cover falling off or deforming, and increasing the safety of use.

[0035] Fiberglass cloth coated with glue: The soft material increases the comfort of use, and the user will not feel hand discomfort during operation.

[0036] Teflon cloth: Teflon cloth (PTFE cloth) also has excellent high temperature resistance and a low friction coefficient, which can effectively prevent hair from sticking and improve smoothness of use.

[0037] Teflon cloth: Teflon cloth not only has good thermal conductivity, but also can evenly distribute heat, reduce local overheating, and protect hair from damage.

[0038] Teflon cloth: The high temperature stability and chemical inertness of Teflon cloth ensure that it will not release harmful substances during use, protecting the health and safety of users.

[0039] Teflon cloth: Its smooth surface and low friction properties make the hair slide more smoothly on the straightening iron, improving the usage experience.

[0040] The beneficial effects of the utility model are as follows:

[0041] In the utility model, the heat-conducting cloth sleeve covers the heating element, which can evenly distribute the heat, so that the hair is heated more evenly, thus avoiding the damage to the hair caused by local overheating.

[0042] The utility model has a high temperature resistant adhesive backing which can maintain good bonding performance in a high temperature environment, thereby ensuring that the bonding between the heat conductive cloth sleeve and the heating element is more firm and is not easy to fall off.

[0043] In the utility model, the annular lower edge is not only bonded to the side wall of the heating element, but also inserted into the annular groove. The double fixing method greatly enhances the stability of the heat-conducting cloth sleeve and prevents displacement or falling off during use. BRIEF DESCRIPTION OF THE DRAWINGS
