Abstract

This utility model discloses a light-powered hair styling device. The device includes a main unit, a curling tube, a light-emitting lamp, and a PCBA control board. The curling tube is connected to the main unit, and the light-emitting lamp is located inside the curling tube. The light-emitting lamp is connected to the PCBA control board via a conductive wire, and an isolation bracket is provided between the light-emitting lamp and the conductive wire. By adding an isolation bracket between the light-emitting lamp and the conductive wire, this utility model utilizes the physical barrier effect of the isolation bracket to block the direct transmission of infrared rays emitted by the light-emitting lamp to the high-temperature radiation conductive wire.

Description

Technical Field

[0001] This utility model relates to the field of hair styling equipment technology, and in particular to a light-powered hair styling equipment. Background Technology

[0002] As a common styling tool, the heating efficiency and user experience of hair styling tools directly affect user needs, and the choice of heating element is the core factor determining these performance characteristics. Currently, most mainstream hair styling tools on the market use PTC (Positive Temperature Coefficient) or MCH (Metal-Ceramic) heating elements as their heating cores. While these heating elements can achieve basic heating functions, they have significant limitations in heating speed—due to their own thermal conductivity characteristics, they often require a long waiting time from startup to reaching the preset working temperature. This not only prolongs the user's styling preparation cycle but also reduces overall ease of use, making it difficult to meet consumers' demand for efficient hair styling tools.

[0003] To overcome this technological bottleneck, the industry has begun exploring more efficient heating solutions, among which carbon fiber lamps have come into focus due to their unique heating advantages. Carbon fiber lamps heat the styling device by radiating light, achieving surface temperatures as high as approximately 700 degrees Celsius. Compared to traditional PTC or MCH heating elements, this significantly accelerates the heating speed of the hair styling device, drastically shortens preheating time, and effectively improves the user experience. More importantly, during the heating process, carbon fiber lamps simultaneously emit infrared rays, especially far-infrared rays beneficial to the human body. These far-infrared rays can penetrate to the scalp surface, acting on the capillaries around the hair follicles, promoting vasodilation and accelerating blood flow. This delivers more oxygen and nutrients to the hair follicles, enabling hair styling while also helping to improve hair follicle health, giving the hair styling device additional care value and broad application prospects.

[0004] However, during actual testing of carbon fiber lamps in hair styling devices, researchers discovered serious safety hazards: due to the continuous high-intensity infrared and high-temperature radiation emitted by the carbon fiber lamps, the internal wires of the hair styling device (especially those near the lamps) are exposed to this radiation environment for extended periods. After only about 10 hours of continuous operation, the wire sheaths show obvious yellowing and aging. As the aging intensifies, the wire sheaths may even burn or break, exposing the internal wire cores. Exposed wire cores not only damage the insulation of the internal circuitry of the hair styling device, posing a short-circuit risk, but also potentially cause electric shock accidents during user operation, directly threatening the user's personal safety. This technical defect has become a key obstacle restricting the widespread application of carbon fiber lamps in the hair styling device field.

[0005] To address the aforementioned issue of wire aging, existing technologies have attempted to improve durability by using high-temperature resistant wire sheaths. However, limited by material costs and processing techniques, high-temperature resistant wires not only significantly increase the manufacturing cost of hair styling devices but also suffer from poor flexibility and adaptability, making it difficult to meet the complex wiring requirements within the devices. Other solutions have attempted to reduce radiation by increasing the distance between the wire and the carbon fiber lamp tube, but this approach increases the overall size of the hair styling device, contradicting the current trend towards miniaturization and portability, and reducing market competitiveness. Therefore, there is an urgent need for a technical solution that can effectively block the aging and burning of the wire caused by the infrared and high-temperature radiation of the carbon fiber lamp tube, while also considering cost control, product size, and safety, to promote the rational application of carbon fiber lamp tubes in the hair styling device field. Utility Model Content

[0006] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a light-powered hair styling device.

[0007] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0008] This utility model provides a light-powered hair styling device, including: a main unit, a curling tube, a light-emitting tube, and a PCBA control board. The curling tube is connected to the main unit, the light-emitting tube is disposed inside the curling tube, the light-emitting tube is connected to the PCBA control board through a conductive wire, and an isolation bracket is provided between the light-emitting tube and the conductive wire.

[0009] In one specific embodiment, the conductive wire includes a first conductor and a second conductor. One end of the first conductor is connected to the PCBA control board, and the other end is arranged along the length direction of the light-emitting tube and connected to the top of the light-emitting tube. One end of the second conductor is connected to the PCBA control board, and the other end is connected to the bottom of the light-emitting tube. The isolation bracket is used to separate the light-emitting tube from the first conductor.

[0010] In one specific embodiment, the isolation bracket includes a mica end and a mica plate. The mica end is disposed at both ends of the light-emitting tube and the light-emitting tube passes through the mica end. The mica plate is connected between the two mica ends. The first wire is disposed along the length direction of the mica plate and passes through the mica end to connect to the top of the light-emitting tube.

[0011] In one specific embodiment, the mica end is further provided with a limiting groove corresponding to the first conductor.

[0012] In one specific embodiment, a temperature fuse is also connected to the middle section of the first conductor, and an NTC temperature sensor is also connected to the PCBA control board, the NTC temperature sensor extending into the inner side of the curling tube.

[0013] In one specific embodiment, the temperature fuse and the light-emitting tube are arranged in parallel, and the horizontal distance between the end of the temperature fuse and the end of the light-emitting tube is 20mm-30mm.

[0014] In one specific embodiment, a fiberglass tube is also sleeved on the outside of the first conductor.

[0015] In one specific embodiment, the first wire is fixed to the mica plate by a wire clamp.

[0016] In one specific embodiment, the curling tube is provided with a light-transmitting hole, and the light-emitting lamp tube generates heat and emits infrared rays when it works. The heat is transferred to the curling tube, and the infrared rays are emitted along the light-transmitting hole.

[0017] In one specific embodiment, the main unit is further provided with an elastic clip assembly on the outside of the curling tube body. The elastic clip assembly includes a compression spring and a clamping member. The compression spring is connected to the main unit, and the clamping member is hinged to the main unit and abuts against the compression spring.

[0018] The advantages of this new light-powered hair styling device compared to existing technologies are as follows: By adding an isolation bracket between the light-emitting tube and the conductive wire, the physical barrier of the isolation bracket directly blocks the direct transmission of infrared rays emitted by the light-emitting tube and high-temperature radiation to the conductive wire. The isolation bracket forms a "radiation barrier," preventing high temperature and infrared rays from directly acting on the outer sheath of the conductive wire. This fundamentally delays or even eliminates the aging, softening, and burning of the conductive wire sheath, effectively avoiding safety accidents such as short circuits and electric shocks, and improving the long-term reliability of the light-powered hair styling device. The invention addresses a key safety hurdle that has hindered the application of carbon fiber lamps in hair styling tools. Furthermore, the isolation bracket is characterized by low material cost and easy processing, eliminating the need to replace expensive, high-temperature resistant conductive wires and effectively controlling manufacturing costs. Simultaneously, the isolation bracket only needs to be placed in the gap between the lamp tube and the conductive wire, without occupying a large amount of space inside the curling tube or main unit, thus avoiding an increase in the size of the hair styling tool and a decrease in portability. This aligns with the current market design trend of "miniaturization and lightweighting" in hair styling tools, balancing technical practicality with product market competitiveness.

In addition, those skilled in the art can combine and integrate the different embodiments or examples described in this specification.

[0031] See Figures 1 to 3 The specific embodiment shown in this utility model discloses a light-powered hair styling device, including: a main unit 10, a curling tube 20, a light-emitting tube 30, and a PCBA control board 40. The curling tube 20 is connected to the main unit 10, the light-emitting tube 30 is disposed inside the curling tube 20, the light-emitting tube 30 is connected to the PCBA control board 40 through a conductive wire 50, and an isolation bracket 60 is provided between the light-emitting tube 30 and the conductive wire 50.

[0032] Specifically, the curling tube 20 is first securely assembled with the main unit 10 using snap-fit ​​connections or threaded fastenings, ensuring that the curling tube 20 will not loosen or shift during hair styling operations. Next, the light-emitting tube 30 (preferably a carbon fiber light-emitting tube, which has high light radiation efficiency and stable heating temperature) is embedded into the pre-reserved mounting groove inside the curling tube 20. A high-temperature resistant insulating pad is attached to the inner wall of the mounting groove to prevent heat loss due to direct contact between the light-emitting tube 30 and the metal inner wall of the curling tube 20, and to prevent the risk of leakage. Then, the PCBA control board 40 is fixed to the circuit board bracket inside the main unit 10, and the positive and negative terminals of the light-emitting tube 30 are connected to the corresponding power supply interfaces of the PCBA control board 40 via conductive wires 50. Simultaneously, the isolation bracket 60 is integrally molded from mica material, with an overall U-shaped structure. Its opening size is adapted to the outer diameter of the light-emitting tube 30, and the side wall thickness of the bracket is 1-2mm, with a length greater than the length of the light-emitting tube 30, ensuring complete shielding of the radiation emitted by the light tube. During assembly, first, the bottom of the isolation bracket 60 is glued and fixed to the mounting groove on the inside of the curling tube 20 with high-temperature resistant adhesive, so that the U-shaped opening of the bracket faces the light tube 30, and a safety gap of 1-2mm is maintained between the bracket and the light tube 30; then, the conductive wire 50 is placed on the side of the isolation bracket 60 away from the light tube 30, and a physical barrier is formed through the side wall of the bracket to block infrared rays and high-temperature radiation from directly acting on the conductive wire 50.

[0033] In other words, by adding an isolation bracket 60 between the light-emitting tube 30 and the conductive wire 50, the physical barrier effect of the isolation bracket 60 can directly block the direct transmission of infrared rays emitted by the light-emitting tube 30 to the high-temperature radiation conductive wire 50. The isolation bracket 60 can form a "radiation barrier," preventing high temperature and infrared rays from directly acting on the outer sheath of the conductive wire 50. This fundamentally delays or even eliminates the aging, softening, and burning of the outer sheath of the conductive wire 50, effectively avoiding safety accidents such as short circuits and electric shocks, improving the long-term reliability of the light-powered hair styling device, and solving the problem of carbon dioxide... The key safety hurdles in the application of fiber lamp tubes in the hair styling tool field are addressed. In addition, the isolation bracket 60 has the characteristics of low material cost and easy processing, eliminating the need to replace the expensive high-temperature resistant conductive wire 50, which can effectively control the production and manufacturing costs. At the same time, the isolation bracket 60 only needs to be placed in the gap between the light-emitting tube 30 and the conductive wire 50, without taking up a large amount of extra space inside the curling tube 20 or the main unit 10, which will not lead to an increase in the size of the hair styling tool or a decrease in portability. It fits the current market design trend of "miniaturization and lightweighting" of hair styling tools, and takes into account both technical practicality and product market competitiveness.

[0034] In one embodiment, the conductive line 50 includes a first conductor 51 and a second conductor 52. One end of the first conductor 51 is connected to the PCBA control board 40, and the other end is arranged along the length direction of the light-emitting tube 30 and connected to the top end of the light-emitting tube 30. One end of the second conductor 52 is connected to the PCBA control board 40, and the other end is connected to the bottom end of the light-emitting tube 30. The isolation bracket 60 is used to separate the light-emitting tube 30 from the first conductor 51.

[0035] Specifically, both the first conductor 51 and the second conductor 52 are made of silicone-insulated wire with a temperature resistance rating of not less than 150 degrees Celsius. The conductor core uses multi-strand tin-plated copper wire, which ensures both stable current transmission and good flexibility to meet the bending wiring requirements inside the hair styling device. The insulation sheath of the conductor is 0.3-0.5mm thick, with a smooth and abrasion-resistant surface to reduce wear when in contact with other components. In addition, one end of the first conductor 51 is connected to the "positive power supply interface of the lamp tube" on the PCBA control board 40 through a tin-plating process; the other end extends along the length of the light-emitting tube 30 (carbon fiber lamp tube), and near the top of the lamp tube, it is fixedly connected to the metal conductive pin at the top of the lamp tube through a crimp terminal. After crimping, an insulating heat-shrink tubing is sleeved on the outside of the terminal to achieve sealed insulation at the connection between the terminal and the conductor. At the same time, one end of the second conductor 52 is also connected to the "negative power supply interface of the lamp tube" on the PCBA control board 40 through a tin-plating process, which is the same as that of the first conductor 51; the other end extends directly upward and connects to the metal conductive pin at the bottom of the light-emitting tube 30.

[0036] In other words, the first conductor 51 and the second conductor 52 are connected to the top and bottom of the light-emitting tube 30, respectively, forming independent positive and negative power supply paths. This avoids the problem of concentrated heat generation in the wire core caused by a single conductor simultaneously bearing both positive and negative current. Furthermore, the use of multi-strand tinned copper wire cores reduces line resistance and current transmission losses, ensuring that the lamp tube can stably obtain the rated operating current and avoiding slow heating or brightness fluctuations due to insufficient power supply. In addition, the isolation bracket 60 effectively blocks the infrared radiation and high-temperature radiation emitted by the carbon fiber lamp tube from affecting the first conductor 51, preventing the outer sheath of the first conductor 51 from yellowing or softening, thus maintaining good insulation performance of the wire core and fundamentally avoiding the risk of short circuits and electric shock.

[0037] In one embodiment, the isolation bracket 60 includes a mica end 61 and a mica plate 62. The mica end 61 is disposed at both ends of the light-emitting tube 30, and the light-emitting tube 30 passes through the mica end 61. The mica plate 62 is connected between the two mica ends 61. The first wire 51 is disposed along the length direction of the mica plate 62 and passes through the mica end 61 to connect to the top end of the light-emitting tube 30.

[0038] Specifically, the mica end 61 is made of muscovite material with a temperature resistance rating of ≥800 degrees Celsius. This material combines excellent high-temperature resistance and insulation, making it suitable for the high-temperature environment during the operation of the light-emitting tube 30. The mica end 61 is designed as an "I"-shaped structure, with a circular through hole in the middle matching the outer diameter of the light-emitting tube 30. This ensures the stability of the tube during installation and buffers minor vibrations during operation. Fixing ears extend from both ends of the end, with mounting holes for connection to the inner wall of the curling tube 20 via screws. Additionally, the mica plate 62 is also made of muscovite material. Based on the circumference of the curling tube 20 and the distance between the two mica ends 61, the mica plate 62 is machined into an "arc-shaped strip"—its length matches the distance between the two ends, and its width covers the area between the light-emitting tube 30 and the first conductor 51, ensuring both heat insulation and structural strength.

[0039] In other words, the framework structure of "mica ends 61 at both ends + mica plate 62 in the middle" forms a three-dimensional protection around the key radiation area of ​​the light-emitting tube 30: the mica ends 61 can block the infrared rays and high-temperature radiation that diffuse outward from both ends of the tube, preventing radiation from bypassing the isolation structure from the ends of the tube and acting on the wire; the middle mica plate 62 directly isolates the tube body from the first wire 51, preventing the outer skin of the first wire 51 from showing signs of yellowing or softening.

[0040] In one embodiment, the mica end 61 is further provided with a limiting groove 611 corresponding to the first conductor 51.

[0041] Specifically, the limiting groove 611 is formed on the side of the mica end 61 facing the first conductor 51. The limiting groove 611 has a U-shaped cross-section, and the groove width matches the outer diameter of the first conductor 51, which ensures that the conductor can be stably embedded in the groove, while avoiding the conductor from being completely embedded and difficult to remove during subsequent maintenance.

[0042] In other words, the limiting groove 611 of the mica end 61 directly limits the insertion position of the first wire 51 through the physical constraint of the U-shaped groove, preventing the wire from deviating from the preset path due to external force during use of the hair styling device (such as flipping, shaking, or collision), and preventing the wire from approaching the high-temperature area of ​​the light tube 30. In addition, the limiting groove 611 and the wire clamp of the mica plate 62 form a continuous "end-middle-end" fixing system: the limiting groove 611 fixes the two ends of the wire (the key positions near the top and bottom of the light tube), and the wire clamp fixes the middle section of the wire, so that the wire as a whole remains smooth and without bending, avoiding wire core breakage or poor contact caused by wire bending.

[0043] In one embodiment, a temperature fuse 70 is also connected to the middle section of the first wire 51, and an NTC temperature sensor 80 is also connected to the PCBA control board 40, the NTC temperature sensor 80 extending into the inside of the curling tube body 20.

[0044] Specifically, when the hair styling device is powered on, the PCBA control board 40 outputs a drive signal to the light-emitting tube 30. The light-emitting tube 30 immediately releases light energy and radiates heat, which is quickly transferred to the curling tube 20, causing it to heat up. Simultaneously, the NTC temperature sensor 80 collects real-time temperature data of the inside of the curling tube 20, converting the analog temperature signal into an electrical signal and transmitting it to the PCBA control board 40. The PCBA control board 40 analyzes the temperature signal using its built-in chip. If the temperature is lower than the preset styling temperature (e.g., 160-200 degrees Celsius), it maintains or increases the power supply to the light-emitting tube 30. When the temperature reaches the preset value, the power supply is reduced or the power supply is stopped to achieve dynamic and stable temperature control. When the NTC temperature sensor 80 malfunctions due to wire breakage, component aging, or other reasons, it cannot transmit an accurate temperature signal to the PCBA control board 40, causing the light tube 30 to continue heating and the temperature of the curling tube 20 to exceed the safety threshold. When the temperature of the temperature fuse 70 near the curling tube 20 reaches its rated melting temperature, the internal fuse melts rapidly, cutting off the power supply circuit between the light tube 30 and the PCBA control board 40. The light tube 30 immediately stops working, and the hair stylist enters the shutdown state.

[0045] In other words, on the one hand, the NTC temperature sensor 80 connected to the PCBA control board 40 extends into the inside of the curling tube 20, which can monitor the temperature changes inside the curling tube 20 in real time and transmit the temperature signal to the PCBA control board 40. The PCBA control board 40 then dynamically adjusts the heating state of the light tube 30 according to the preset temperature threshold, achieving precise temperature control under normal operating conditions and avoiding damage to hair quality or safety hazards caused by excessive temperature. On the other hand, a temperature fuse 70 is installed in the middle of the first wire 51 connecting the light tube 30 and the PCBA control board 40. This temperature fuse 70 can serve as a backup safety protection unit. If the NTC temperature sensor 80 malfunctions due to aging, poor contact, external interference, or other factors, or if the temperature control logic of the PCBA control board 40 is abnormal, causing the normal temperature to drop, the circuit will be closed. In the event of a control failure, the temperature fuse 70 can directly monitor the actual temperature inside the curling tube 20. Once the temperature exceeds its preset safety threshold, the temperature fuse 70 will immediately and automatically burn out, cutting off the power supply circuit to the light tube 30 and forcing the hair stylist to stop, thus completely blocking the risk of the temperature continuing to rise. Compared to the traditional single temperature control scheme that relies solely on the NTC and circuit board, this scheme forms a dual insurance mechanism of "active monitoring and control + passive emergency cut-off" through the coordinated operation of the NTC temperature sensor 80 and the temperature fuse 70. Even in extreme scenarios where a single protection unit fails, it can still reliably ensure that the hair stylist will not experience temperature runaway, fundamentally reducing the probability of safety accidents such as equipment damage, hair damage, or even fire caused by high temperatures, and significantly improving the safety and reliability of the product.

[0046] In one embodiment, the temperature fuse 70 and the light-emitting tube 30 are arranged in parallel, and the horizontal distance between the ends of the temperature fuse 70 and the light-emitting tube 30 is 20mm-30mm.

[0047] Specifically, when the light-emitting tube 30 is working, the heat is concentrated in the middle area, where the central temperature can reach about 700 degrees Celsius, while the end, being close to the mica end 61 and the heat dissipation structure, has a relatively lower temperature (about 300-350 degrees Celsius). Maintaining a 20mm-30mm gap between the temperature fuse 70 and the end of the tube completely avoids the high-temperature zone in the middle of the tube, preventing the fuse from being exposed to high temperatures for extended periods, thus accelerating the aging of the internal fuse wire, significantly extending its service life, and reducing equipment failures caused by premature fuse aging. In addition, the 20mm-30mm gap design prevents the temperature fuse 70 from accidentally blowing due to its proximity to the high-temperature zone in the middle of the tube (such as accidental triggering due to high temperature during normal operation), while also ensuring that the temperature fuse 70 can promptly detect temperature changes and blow when the entire curling tube 20 overheats (such as when the NTC malfunctions and heat is conducted to the tube wall). Meanwhile, the temperature fuse 70 is positioned parallel to the lamp tube, allowing it to receive heat more evenly from the curling tube 20. This avoids delayed temperature sensing due to angular deviations, ensuring rapid circuit cutoff in case of temperature runaway and completely preventing danger, further enhancing the reliability of the double safety measure. Furthermore, the temperature fuse 70 can be positioned at either the front or rear of the lamp tube 30, providing flexibility in the internal structure layout of the hair styling device. This flexible placement allows the temperature fuse solution to adapt to different sizes and shapes of curling tubes 20 without requiring adjustments to the overall structure due to fuse placement limitations, thus improving the compatibility and practicality of the technical solution.

[0048] In one embodiment, the first wire 51 is fixed to the mica plate 62 by a wire clamp.

[0049] Specifically, a high-temperature resistant mica material rivet clamp adapted to the thickness of the mica plate 62 is selected. The clamp body has a U-shaped structure, and an arc-shaped groove matching the outer diameter of the first conductor 51 is opened on the inner side. A 0.2mm thick high-temperature resistant silicone pad (temperature resistance ≥300 degrees) is pasted on the inner wall of the groove, which not only avoids damage to the insulation layer of the first conductor 51 when the clamp is tightened, but also enhances the fixing friction. The rivet is a mica rivet of the same material, and the length matches the thickness of the mica plate 62 (ensuring that there is no excess protrusion after penetrating the mica plate 62).

[0050] In other words, by fixing the first wire 51 to the mica plate 62 with rivet clamps, the swing amplitude of the first wire 51 can be completely limited, ensuring that the temperature protection component 70 is always in the preset temperature sensing position, so that it can accurately capture the actual temperature change of the curling tube 20, which not only avoids accidental melting during normal operation, but also ensures a rapid response when out of control, thus improving the reliability of safety protection.

[0051] In one embodiment, a fiberglass tube 90 is also sleeved on the outside of the first conductor 51.

[0052] Specifically, based on the outer diameter and length of the first conductor 51, an alkali-free fiberglass tube 90 with a temperature resistance rating of ≥300 degrees and an inner diameter 0.5mm-1mm larger than the outer diameter of the first conductor 51 is selected (it has excellent insulation performance and strong aging resistance).

[0053] In other words, the fiberglass tube 90, sleeved on the outside of the first conductor 51, effectively isolates it from external physical impacts, preventing the temperature fuse 70 from being damaged by external pressure or scratches, or its pins from falling off. Simultaneously, the fiberglass tube 90 also serves to isolate the first conductor 51 and provides double insulation with the wire sheath. Furthermore, if the infrared radiation emitted by the light-emitting tube 30 directly irradiates the fiberglass tube 90, it will accelerate the aging process of the fiberglass tube 90, leading to a decrease in its strength, a decline in its insulation performance, and a shortened service life. The mica plate 62, however, can block infrared radiation, placing the fiberglass tube 90 in a low-radiation environment. Combined with the high-temperature resistance of the fiberglass tube 90 itself, this slows down the aging process.

[0054] In one embodiment, the curling tube 20 is provided with a light-transmitting hole 21, and the light-emitting lamp tube 30 generates heat and emits infrared rays when it works. The heat is transferred to the curling tube 20, and the infrared rays are emitted along the light-transmitting hole 21.

[0055] Specifically, a light-transmitting hole 21 is formed along the length of the wall of the curling tube 20 to ensure that infrared rays can evenly cover the circumferential area of ​​the curling tube 20. At the same time, a layer of high-temperature resistant quartz glass is covered on the outside of the light-transmitting hole 21. The quartz glass is sealed to the wall of the curling tube 20 by a high-temperature resistant silicone sealing ring. The quartz glass has high infrared transmittance and can prevent hair, dust or sweat from entering the interior of the curling tube 20 during the hair styling process, so as to avoid contaminating the light-emitting lamp tube 30 or affecting its heat dissipation.

[0056] In other words, the light tube 30 can not only generate heat, but also emit infrared rays at the same time. The infrared rays can penetrate the hair strands, heat them from the inside, accelerate moisture evaporation, promote the closure of the hair cuticles, reduce heat damage, and protect the hair quality. In addition, the infrared rays can also promote blood circulation, enhance the natural shine and elasticity of the hair strands, and make the curling effect more natural and lasting. Through the light-transmitting holes 21 set along the axial direction of the curling tube 20, the infrared rays can be emitted evenly, ensuring the maximization of the hair styling effect throughout the entire curling process.

[0057] In one embodiment, the host 10 is further provided with an elastic clip assembly 100 on the outside of the curling tube body 20. The elastic clip assembly 100 includes a compression spring and a clamping member. The compression spring is connected to the host 10, and the clamping member is hinged to the host 10 and abuts against the compression spring.

[0058] Specifically, when the clamping member is pressed, the spring member is compressed under the pressure. At this time, the hair can be wrapped around the curling tube 20. Then, the clamping member is released, and the spring member quickly returns to its original position using its elasticity, so that the clamping member and the curling tube 20 cooperate to clamp the hair.

[0059] In other words, the design of the elastic clip assembly 100 allows users to quickly clamp and release hair. By simply pressing and releasing the clamping element, hair can be secured and released, greatly improving the convenience and efficiency of hair styling operations. Furthermore, the elasticity of the spring and the structural design of the clamping element ensure that the hair is firmly clamped onto the curling tube 20. Even if the hair is subjected to a certain amount of tension or external force during the hair styling process, the clamping element and the spring element can work together to maintain a stable clamped state. In addition, through the stable clamping effect, the elastic clip assembly 100 ensures that the hair is evenly heated and styled during the curling process, which helps improve the hair styling effect while reducing safety hazards caused by loose or falling hair.

[0060] In one embodiment, a sealing head 110 is also connected to the end of the curling tube 20 away from the main unit 10.

[0061] Specifically, the sealing head 110 effectively prevents heat leakage from the inside of the curling tube 20. During the curling process, excessive heat leakage not only reduces the curling effect but may also pose safety hazards such as burns to the user. The sealing head 110 reduces heat leakage, allowing the heat inside the curling tube 20 to concentrate more effectively, thus improving the curling effect. Furthermore, the sealing head 110 prevents external impurities (such as dust and moisture) from entering the curling tube 20. These impurities could damage the internal structure of the curling tube 20, affecting its lifespan and performance. The sealing effect of the sealing head 110 effectively blocks the entry of these impurities, protecting the internal structure of the curling tube 20 from damage.

[0062] In one embodiment, the end of the sealing head 110 away from the curling tube body 20 is also connected to a handheld component 120.

[0063] Specifically, the handheld component 120 allows users to more easily rotate and operate the curling tube 20, making it easier to style and set the hair, and preventing burns. Furthermore, the handheld component 120 allows users to more easily adjust the angle and direction of the curling tube 20, enabling more diverse hairstyle designs and enhancing operational flexibility and precision.

[0064] In one embodiment, the host 10 is provided with a control switch, which is electrically connected to the PCBA control board 40.

[0065] Specifically, the operating power of the light-emitting tube 30 can be adjusted by controlling the switch. The operating power of the light-emitting tube 30 can be set to 30-60W. When the operating temperature is set to 60 degrees Celsius, it is ensured that the light-emitting tube 30 can work and generate infrared light to meet the needs of use in a low-power state.

[0066] In other words, for the 30-60W operating power range of the light tube 30, three power parameters can be set: low 30W, medium 45W, and high 60W, ensuring stable power at each level without significant fluctuations. Through the three-level control switch, users can freely adjust the power according to hair type (e.g., 30W for fine hair, 60W for coarse hair) and styling needs (e.g., 30W for low-temperature care, 60W for quick curls), adapting to different usage scenarios. In particular, the combination of low 30W and low 60°C meets users' needs for "low-temperature styling and reduced hair damage" (e.g., hair care after dyeing and perming), solving the problem of traditional hair styling tools having fixed power and being unable to adapt to various hair types, thus expanding the product's applicability.

[0067] Specifically, the other structures of the host 10 adopt existing publicly available technologies, which will not be elaborated on here.

[0068] 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.
