Description

TECHNICAL FIELD

[0001] The utility model relates to hairdressing device technical field especially relates to a light energy straightener. BACKGROUND

[0002] As a widely used personal care appliance, the main function of the straightener is to heat the hair through the heating element to achieve the effect of straightening or curling the hair. Traditionally, the core heating component of the straightener is a PTC (Positive Temperature Coefficient) heating body. Due to its automatic temperature limiting feature, i.e. the resistance increases when the temperature rises, thereby limiting the current passing through to prevent overheating, this feature makes it have a significant advantage in safety.

[0003] However, although the PTC heating body performs well in safety, it also has some obvious limitations in actual application. The primary problem is that the temperature rising speed is relatively slow. Due to the characteristics of PTC material, it takes a certain time to reach the ideal operating temperature during the heating process, which is undoubtedly an inconvenience for consumers who pursue fast styling effects. In addition, the PTC heating body mainly produces heat conduction and heat convection effects when working, lacking the function of directly emitting infrared rays.

[0004] As an electromagnetic wave, the thermal energy of infrared rays can directly penetrate the hair surface layer and act on the moisture and protein structure inside the hair, helping to reduce thermal damage and promote faster and more uniform heating of the hair. Therefore, the straightener with infrared emission function not only can improve the styling efficiency, but also can protect the hair quality to a certain extent and reduce the problems of dryness and splitting caused by high temperature.

[0005] In summary, the existing straightener using PTC heating body, although it ensures the safety of use, but there are deficiencies in the temperature rising speed and functional diversity, especially the lack of infrared emission ability, which limits its further improvement in hair styling effect and user experience. Therefore, developing a new type of straightener that can quickly heat and has infrared emission function has become an important direction of current hair styling tool technology innovation.

[0032] Referring to Figures 1 to 4The utility model discloses a light energy straightening iron, including: upper handle subassembly 10 and the lower handle subassembly 20 of articulation in upper handle subassembly 10, upper handle subassembly 10 and lower handle subassembly 20 all are equipped with installation cavity (not shown in the drawing), installation cavity is equipped with straightening board 30 and light emitting part 40, and light emitting part 40 is located the inside of straightening board 30, upper handle subassembly 10 or lower handle subassembly 20 still are equipped with control panel (not shown in the drawing), light emitting part 40 is electrically connected in control panel, straightening board 30 is equipped with the light transmission hole (not shown in the drawing) along the axial direction (other direction also can, as long as can evenly emit light), and control panel controls light emitting part 40 work produces heat and emits infrared, and the heat is transferred to straightening board 30, and infrared is emitted along the light transmission hole.

[0033] Specifically, by adopting light emitting part 40 as heating element, light emitting part 40 can not only produce heat when working, but also emit infrared, since the heating response speed of light emitting part 40 is fast, therefore straightening iron can quickly reach the ideal working temperature, greatly shorten the preheating time, improve the styling efficiency of user, and the infrared emitted by light emitting part 40 when working can penetrate hair, directly act on the moisture and protein structure inside hair, help to reduce heat damage, make hair more supple and lustrous. In addition, heat is directly transferred to the surface of straightening board 30 through light emitting part 40 inside straightening board 30, reduces the energy loss in heat transfer process, makes the heat energy utilization more efficient. In addition, the work of light emitting part 40 can be accurately controlled through control panel, so that user can adjust the temperature and infrared emission intensity of straightening iron according to individual needs, to increase the flexibility and personalization of use.

[0034] In an embodiment, the installation cavity is provided with a fixing ring 50 at both ends of the light emitting part 40, and the light emitting part 40 is arranged in the fixing ring 50 through the pins or connecting parts at both ends thereof.

[0035] Specifically, the fixing ring 50 is usually made of insulating material, such as ceramic, plastic or high-temperature-resistant rubber, to ensure good insulation performance and heat resistance. In the installation cavity, the fixing ring 50 is arranged at both ends of the light emitting part 40, and the light emitting part 40 is arranged in the fixing ring 50 through the pins or connecting parts at both ends thereof, to ensure that the light emitting part 40 maintains a fixed position in the installation cavity. The fixing ring 50 not only fixes the light emitting part 40, but also isolates the direct contact between the light emitting part 40 and the metal wall of the installation cavity through its insulating material, to prevent electrical short circuit.

[0036] That is, the design of the fixing ring 50 ensures the stable position of the light emitting member 40 in the installation cavity, prevents loosening or displacement due to vibration or external force, and improves the overall stability of the light energy straightener. In addition, the insulating material of the fixing ring 50 effectively isolates the direct contact between the light emitting member 40 and the metal wall of the installation cavity, preventing the risk of electrical short circuit and improving the electrical safety of the product.

[0037] In an embodiment, the fixing ring 50 is made of ceramic material.

[0038] Specifically, the ceramic material has very high resistivity and breakdown voltage, which can effectively isolate the direct contact between the light emitting member 40 and the metal wall of the installation cavity, prevent electrical short circuit and leakage, and improve the electrical safety of the product. In addition, the ceramic material can withstand long-term work in high temperature environment and will not soften or deform due to temperature rise, thereby ensuring the stability and reliability of the light energy straightener in high temperature. In addition, the ceramic fixing ring 50 has high hardness and strength, which can withstand the vibration and impact force generated by the light emitting member 40 during work, preventing the light emitting member 40 from loosening or damaging.

[0039] In an embodiment, the back side of the light emitting member 40 is further provided with a limiting plate 60, and the straightening plate 30 is provided with a limiting groove 31 corresponding to the limiting plate 60.

[0040] Specifically, the cross section of the limiting plate 60 is arc-shaped, and the limiting plate 60 is provided with protrusions on both sides and along the length direction. The straightening plate 30 is provided with a limiting groove 31 corresponding to the protrusions in the axial direction (i.e. the length direction of the limiting plate 60). That is, the cross section of the limiting plate 60 is arc-shaped, which is designed to better fit the back profile of the light emitting member 40, ensure the close contact between the limiting plate 60 and the light emitting member 40, and provide stable support, effectively preventing the light emitting member 40 from shifting or shaking, improving the overall stability and reliability of the light energy straightener. In addition, the limiting plate 60 is provided with protrusions on both sides and along the length direction, which are used as positioning elements to accurately match the limiting groove 31 on the straightening plate 30, ensuring the accurate positioning of the limiting plate 60 during installation.

[0041] In an embodiment, the back side of the installation cavity of the limiting plate 60 is further provided with a heat insulating member 70.

[0042] Specifically, in order to further reduce the impact of the heat generated by the light-emitting element 40 on other elements inside the installation cavity, while improving the transmission efficiency of thermal energy to the straightening iron 30, a heat insulation element 70 is additionally provided on the back side of the installation cavity. The heat insulation element 70 is made of heat insulation cotton, which is a material with excellent heat insulation properties and can effectively block the transmission of heat while maintaining a certain degree of flexibility and corrosion resistance. The arrangement of the heat insulation element 70 not only blocks the transmission of heat generated by the light-emitting element 40 to other elements inside the installation cavity, but also forces the heat to be transmitted more to the straightening iron 30, which helps to optimize the heat transfer path and improve the efficiency of heat energy utilization.

[0043] In an embodiment, the installation cavity on the back side of the straightening iron 30 is also provided with a support frame 80, and the straightening iron 30 is connected to the support frame 80.

[0044] Referring to Figure 2 As shown, the support frame 80 is composed of an upper end and a lower end. Specifically, in order to enhance the stability and support of the straightening iron 30, a support frame 80 is additionally provided on the back side of the installation cavity. The support frame 80 not only serves to support and fix the straightening iron 30, but also optimizes the overall structure and improves the durability and safety of the light energy straightener. In addition, the support frame 80 is composed of two parts, an upper end and a lower end, which facilitates installation and disassembly. The support frame 80 is made of high-strength, corrosion-resistant materials such as stainless steel or aluminum alloy to ensure that it has sufficient strength and stability during use.

[0045] That is, the design of the support frame 80 enhances the stability of the straightening iron 30, reducing the risk of loosening or damage due to vibration or external forces, which helps to improve the overall stability and durability of the light energy straightener.

[0046] In an embodiment, the straightening iron 30 is also provided with a light-transmitting sealing element 90 corresponding to the position of the light-transmitting hole.

[0047] Specifically, in order to ensure that the light-transmitting hole can effectively transmit infrared light and prevent heat leakage and external impurities from entering the interior of the straightening iron 30, a light-transmitting sealing element 90 is provided on the straightening iron 30 corresponding to the position of the light-transmitting hole. In specific implementation, the light-transmitting sealing element 90 is designed as a ring-shaped or sheet-shaped structure that closely fits the inner wall of the straightening iron 30, and its material is selected from materials with high thermal stability, good light-transmitting properties and certain elasticity, such as transparent silicone, polyimide film or special optical glass, etc. These materials can maintain stable light-transmitting properties in high-temperature environments while having a certain sealing effect.

[0048] That is, the design of the light-transmitting seal 90 ensures that infrared rays can smoothly pass through the light-transmitting hole without being blocked by the material or structure of the seal, which guarantees the effective use of infrared rays during heating and hair styling of the hair straightener and improves the hair styling effect. In addition, the light-transmitting seal 90 not only has light-transmitting property but also has certain heat insulation performance. It can effectively prevent the heat inside the hair straightener 30 from leaking to the external environment through the light-transmitting hole, thereby improving the thermal efficiency and use safety of the hair straightener. In addition, the sealing performance of the light-transmitting seal 90 can also prevent external impurities such as dust and moisture from entering the inside of the hair straightener 30 through the light-transmitting hole, thereby protecting the light-emitting element 40 and electronic components inside the hair straightener 30 from damage and prolonging the service life of the hair straightener.

[0049] In an embodiment, the light-emitting element 40 is tubular or bulb-shaped.

[0050] Specifically, referring to Embodiment I shown in Figure 2 and Figure 3 , the light-emitting element 40 is tubular. The design of the tubular light-emitting element 40 allows light to uniformly irradiate onto the hair. Preferably, the light-emitting element 40 is a halogen lamp. As a light source, the halogen lamp has the advantages of stable color temperature and high brightness, which allows the light-emitting element 40 to provide a stable light environment during hair curling and avoids the problem of affecting the hair curling effect due to fluctuations in the light source.

[0051] Referring to Embodiment II shown in Figure 4 , the light-emitting element 40 is bulb-shaped. Each fixing ring 50 is provided with one light-emitting element 40. Preferably, the light-emitting element 40 is a halogen lamp. As a light source, the halogen lamp has the advantages of stable color temperature and high brightness, which allows the light-emitting element 40 to provide a stable light environment during hair curling and avoids the problem of affecting the hair curling effect due to fluctuations in the light source.

[0052] In an embodiment, the upper handle assembly 10 or the lower handle assembly 20 is further provided with a temperature sensor 100, which extends into the area of the light-emitting element 40.

[0053] Specifically, to monitor the temperature of the area of the light emitting member 40 in real time, ensure the safety and stability of the product during operation, a temperature sensor 100 is added to the upper handle assembly 10 or the lower handle assembly 20. The sensing end or probe part of the temperature sensor 100 extends into the area of the light emitting member 40, can directly measure the temperature of the area, and feed back the temperature information to the control panel to achieve accurate control of the temperature of the light emitting member 40. The temperature sensor 100 uses high-precision, fast-response thermistors, thermocouples, or infrared temperature sensors 100, etc. to ensure the accuracy and real-time of the measurement. The control panel sets an over-temperature protection mechanism according to the signal of the temperature sensor 100. When the temperature of the area of the light emitting member 40 exceeds the preset safety threshold, the control panel will automatically cut off the heating power supply to prevent safety hazards such as fire and burns caused by excessive temperature.

[0054] That is, by monitoring the temperature of the area of the light emitting member 40 in real time, overheating conditions can be discovered and handled in a timely manner, effectively preventing safety hazards such as fires and burns caused by excessive temperature, and improving the overall safety of the light energy straightening iron. In addition, the real-time temperature information provided by the temperature sensor 100 allows the control panel to accurately adjust the heating power of the light emitting member 40 to keep the temperature within the optimal working range, which helps to optimize heating efficiency, reduce energy waste, and improve the energy efficiency ratio of the light energy straightening iron. In addition, by accurately controlling the temperature of the light emitting member 40, the light energy straightening iron can maintain stable heating effects during operation, avoiding problems such as poor hair styling results or burns caused by temperature fluctuations, which helps to improve user experience and meet users' higher demands for hair styling products.

[0055] In an embodiment, the straightening plate 30 is made of aluminum material.

[0056] Specifically, the straightening plate 30 is made of high-purity aluminum or aluminum alloy material, which has good thermal conductivity and mechanical strength, and can meet the high requirements of the light energy straightening iron on the straightening plate 30. In addition, aluminum material has good thermal conductivity, which can quickly transfer the heat generated by the light emitting member 40 to the surface of the straightening plate 30, thereby achieving rapid heating of the hair, which helps to improve the heating efficiency of the light energy straightening iron and shorten the heating time. In addition, through the high-efficiency thermal conductivity of the aluminum material and the uniform heating element design on the surface of the straightening plate 30, uniform heat distribution can be achieved, ensuring that the hair is uniformly heated during the heating process, which helps to reduce damage to the hair caused by local overheating and improve the hair styling effect. In addition, aluminum material has relatively light density and high mechanical strength, so that the straightening plate 30 has relatively light weight and high durability while ensuring heating efficiency, which helps to reduce the overall weight of the light energy straightening iron and improve user experience.

[0057] Specifically, the other structures of the upper handle assembly 10 and the lower handle assembly 20 adopt existing publicly available technologies, which will not be elaborated on here.

[0058] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
