Description

Technical Field

[0001] This utility model relates to the field of hair dryer technology, and in particular to an infrared heating hair dryer. Background Technology

[0002] In the field of personal care appliances, infrared heated hair dryers, as devices that integrate rapid drying and styling functions, are widely used in hair salons and daily home care because they can directly heat the surface of objects using infrared radiation, achieving a highly efficient and uniform heating effect. Compared with traditional heating methods, infrared heating technology has significant advantages such as fast heating speed, low energy consumption, and high thermal efficiency, which can significantly improve the user experience and meet diverse usage needs.

[0003] However, infrared-heated hair dryers currently on the market generally have a significant safety hazard in their design: their infrared heating element, i.e., the infrared lamp, is usually directly and unprotectedly fixed inside the hair dryer body. While this design ensures good heating performance during normal use, the infrared lamp is highly susceptible to breakage in the event of accidental collisions, drops, or other forms of external impact. Once the lamp breaks, the glass fragments inside may be blown out through the air outlet by the powerful airflow generated by the motor assembly inside the hair dryer, directly threatening the user's personal safety, especially sensitive areas such as the face and eyes, potentially causing serious physical injury.

[0004] Therefore, developing a technology that can effectively isolate the infrared lamp tube from the airflow channel, ensuring that even if the infrared lamp tube breaks, its fragments will not be carried out of the hair dryer by the airflow, thereby protecting user safety, has become an urgent technical problem to be solved in this field. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an infrared heating hair dryer.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] This utility model provides an infrared heating hair dryer, including: a main unit, the main unit having a heating frame assembly, an air duct cylinder, a heat insulation cylinder, an infrared lamp, a reflector cup, and a protective cover inside, the front end of the heating frame assembly being located inside the air duct cylinder, the heat insulation cylinder being located inside the heating frame assembly, the reflector cup being connected to the front end of the heating frame assembly, the protective cover being connected to the front end of the reflector cup, the heat insulation cylinder, the reflector cup, and the protective cover forming a receiving cavity, and the infrared lamp being located inside the receiving cavity.

[0008] In one specific embodiment, the rear end of the heat insulation cylinder is provided with a slot, and the infrared lamp is located inside the heat insulation cylinder and connected to the slot.

[0009] In one specific embodiment, the protective cover is provided with a plurality of micropores, the diameter of which is 0.1mm-0.6mm.

[0010] In one specific embodiment, a power component is further provided at the rear end of the heating frame assembly. The airflow generated by the power component is heated by the heating frame assembly and then blown out along the gap between the heating frame assembly and the air duct cylinder.

[0011] In one specific embodiment, the power assembly consists of a motor and an impeller, with the impeller being driven to the motor.

[0012] In one specific embodiment, the heating frame assembly consists of a support frame and a heating element.

[0013] In one specific embodiment, the host is further provided with a PCB board, and the infrared lamp, the heating frame assembly and the power assembly are all electrically connected to the PCB board.

[0014] In one specific embodiment, the heat-insulating cylinder is made of mica, plastic, or glass.

[0015] In one specific embodiment, the protective cover is made of metal, glass, or plastic material.

[0016] In one specific embodiment, the reflector cup is made of a metallic material.

[0017] Compared with existing technologies, the advantages of this infrared heating hair dryer are as follows: By placing the infrared lamp inside a cavity composed of a heat-insulating cylinder, a reflector cup, and a protective cover, this design ensures that even if the infrared lamp breaks due to accidental collision, drop, or other external forces during use, the glass fragments will be completely confined within the cavity and will not come into contact with the airflow channel inside the hair dryer. Therefore, when the airflow blows out along the gap between the heating element assembly and the air duct cylinder, it will not carry any fragments out of the cavity, thus completely eliminating the risk of injury to the human body that may be caused by the breakage of the infrared lamp in traditional designs, and improving the safety of the product.

[0029] See Figures 1 to 2 The specific embodiment shown in this utility model discloses an infrared heating hair dryer, including: a main unit 10, wherein the main unit 10 is provided with a heating frame assembly 20, an air duct cylinder 30, a heat insulation cylinder 40, an infrared lamp tube 50, a reflector cup 60, and a protective cover 70. The front end of the heating frame assembly 20 is located inside the air duct cylinder 30, the heat insulation cylinder 40 is located inside the heating frame assembly 20, the reflector cup 60 is connected to the front end of the heating frame assembly 20, and the protective cover 70 is connected to the front end of the reflector cup 60. The heat insulation cylinder 40, the reflector cup 60, and the protective cover 70 form a receiving cavity, and the infrared lamp tube 50 is located inside the receiving cavity.

[0030] Specifically, the air duct body 30 is installed in a pre-set fixed position inside the main unit 10. The air duct body 30 is made of a material with certain strength and heat resistance. Additionally, the heating frame assembly 20 is installed inside the main unit 10, with its front end precisely positioned inside the air duct body 30. Furthermore, a heat-insulating sleeve 40 is placed inside the heating frame assembly 20. The heat-insulating sleeve 40 uses high-efficiency heat-insulating materials, such as ceramic fiber or aerogel felt. The heat-insulating sleeve 40 and the heating frame assembly 20 are connected using appropriate methods, such as snap-fit ​​or screw fixing. Finally, a reflector cup 60 is connected to the front end of the heating frame assembly 20. The reflector cup 60 is typically made of a material with high reflectivity, such as aluminum or stainless steel, and its inner surface undergoes special treatment, such as polishing or coating, to improve the reflection efficiency of infrared rays. The reflector cup 60 is designed with a specific curved surface, such as a parabola or ellipsoid, to focus and reflect the infrared rays emitted by the infrared lamp tube 50, allowing the infrared rays to be more concentrated on the area to be heated, thus enhancing the heating effect. The reflector cup 60 can be connected to the heating frame assembly 20 by welding or riveting. Additionally, a protective cover 70 is connected to the front end of the reflector cup 60, forming a receiving cavity together with the heat-insulating cylinder 40 and the reflector cup 60. The protective cover 70 is made of transparent or semi-transparent high-temperature resistant material, such as high-temperature resistant glass or polycarbonate, ensuring that infrared rays can pass through while also providing physical protection for the infrared lamp tube 50, preventing external objects from directly contacting it. The protective cover 70 and the reflector cup 60 are sealed together, for example, using rubber sealing rings or silicone adhesive, ensuring good sealing of the receiving cavity.

[0031] When the hair dryer is turned on, the power unit 80 starts to work and generate airflow. The airflow is blown out along the gap between the heating element 20 and the air duct 30. Since the infrared lamp 50 is located inside the receiving cavity, the airflow does not pass through the receiving cavity, but flows directly from the gap to the air outlet, thus realizing the functions of drying and styling hair.

[0032] In other words, by placing the infrared lamp 50 inside a cavity comprised of a heat-insulating cylinder 40, a reflector cup 60, and a protective cover 70, this design ensures that even if the infrared lamp 50 breaks due to accidental collision, drop, or other external forces during use of the hair dryer, its glass fragments will be completely confined within the cavity and cannot come into contact with the airflow channels inside the hair dryer. Therefore, when the airflow generated by the power assembly 80 blows out along the gap between the heating element assembly 20 and the air duct cylinder 30, it will not carry any fragments out of the cavity, thus completely eliminating the risk of injury to the human body that may be caused by the breakage of the infrared lamp 50 in traditional designs, and improving product safety. In addition, the curved design of the reflector cup 60 can focus and reflect the infrared rays emitted by the infrared lamp 50, allowing the infrared rays to be directed more concentratedly towards the area that needs to be heated, reducing infrared scattering and waste, and improving the utilization rate of infrared rays.

[0033] In one embodiment, the rear end of the heat insulation cylinder 40 is provided with a slot 41, and the infrared lamp tube 50 is located inside the heat insulation cylinder 40 and connected to the slot 41.

[0034] Specifically, the slot 41 at the rear end of the heat insulation cylinder 40 provides a stable and precise installation position for the infrared lamp 50. By connecting the infrared lamp 50 to the slot 41, the position of the infrared lamp 50 can be effectively fixed, preventing it from shaking or shifting due to vibration, airflow impact, or other factors during the operation of the hair dryer. This ensures that the infrared lamp 50 is always in the correct working position and emits infrared rays stably, thereby guaranteeing the heating performance and shaping effect of the hair dryer.

[0035] In one embodiment, the protective cover 70 is provided with a plurality of micropores, the diameter of which is 0.1mm-0.6mm.

[0036] Specifically, the protective cover 70 is provided with micropores with a diameter of 0.1mm-0.6mm, which provides a channel for infrared rays to escape while ensuring the structural strength of the protective cover 70. Compared with a protective cover 70 without micropores, this design reduces the reflection and absorption of infrared rays on the surface of the protective cover 70, allowing more infrared rays to pass through the protective cover 70 and radiate to the outside, thereby improving the infrared radiation efficiency and enhancing the heating effect of the hair dryer. In addition, the infrared lamp 50 generates a lot of heat when it is working. If this heat cannot be dissipated in time, the temperature inside the housing cavity will rise, which will not only affect the service life of the infrared lamp 50, but may also damage other components. The micropores on the protective cover 70 act as heat dissipation channels, allowing the hot air inside the housing cavity to exchange heat with the outside air through convection, accelerating heat dissipation, thereby effectively reducing the temperature inside the housing cavity and ensuring the normal operation of the infrared lamp 50.

[0037] In one embodiment, the rear end of the heating frame assembly 20 is further provided with a power assembly 80, and the airflow generated by the power assembly 80 is heated by the heating frame assembly 20 and then blown out along the gap between the heating frame assembly 20 and the air duct cylinder 30.

[0038] Specifically, the airflow generated by the power component 80 can quickly pass through the heating element assembly 20, allowing the heat generated by the heating element to be transferred to the airflow in a timely manner, achieving rapid heating. Compared with traditional heating methods, this design can significantly shorten the heating time and improve the efficiency of the hair dryer. For example, the airflow can be heated to a suitable temperature in a short time, meeting the user's need for quick hair drying. Since the airflow is blown out evenly along the gap between the heating element assembly 20 and the air duct body 30, the airflow distribution at the air outlet is uniform, which allows the heated object (such as hair) to receive uniform hot air, avoiding the problems of local overheating or underheating, and improving the styling effect and user comfort of the hair dryer. In addition, placing the power component 80 at the rear end of the heating element assembly 20 makes full use of the internal space of the hair dryer, making the entire structure more compact. This design not only reduces the size of the hair dryer, making it easier to carry and store, but also reduces production costs.

[0039] In one embodiment, the power assembly 80 consists of a motor and an impeller, with the impeller being driven to the motor.

[0040] Specifically, the appropriate motor type should be selected based on factors such as the power requirements of the hair dryer, the usage scenario, and cost control. Common types include DC brushed motors, DC brushless motors, and AC motors. Additionally, suitable fasteners, such as screws and nuts, should be used to securely fix the motor in its mounting position. The appropriate impeller type should be selected based on the airflow and air pressure requirements of the hair dryer, as well as the motor's speed characteristics. Common impeller types include centrifugal impellers and axial impellers. The impeller is typically connected to the motor shaft via a key connection, a flat key connection, or a set screw connection.

[0041] In other words, the motor drives the impeller to rotate at high speed, which can generate a strong airflow. The generated airflow is heated by the heating frame assembly 20 and then blown out along the gap between the heating frame assembly 20 and the air duct cylinder 30.

[0042] In one embodiment, the heating frame assembly 20 consists of a support frame and a heating element.

[0043] Specifically, the support frame adopts a frame design, and the heating element can be an electric heating wire or a mica heating plate. The support frame structure provides stable support for the heating element, ensuring that it will not loosen, deform, or be damaged during operation due to vibration, collision, or its own weight. Even under prolonged use or frequent movement of the hair dryer, the heating frame assembly 20 maintains a stable structure, ensuring the normal operation of the hair dryer.

[0044] In one embodiment, the host 10 is further provided with a PCB board 90, and the infrared lamp tube 50, the heating frame assembly 20 and the power assembly 80 are all electrically connected to the PCB board 90.

[0045] Specifically, the infrared lamp 50, heating frame assembly 20, and power unit 80 are centrally controlled via the PCB board 90. Users can control the operating status of all components through a single control panel or operating interface, simplifying the operation process and improving ease of use. For example, users can simultaneously activate the infrared lamp 50, heating frame assembly 20, and power unit 80 by pressing a single button, achieving functions such as drying and heating. Furthermore, the PCB board 90 can uniformly manage and adjust the operating parameters of each component. For instance, based on different usage scenarios and needs, the control program on the PCB board 90 automatically adjusts the luminous intensity of the infrared lamp 50, the temperature of the heating frame assembly 20, and the rotation speed of the power unit 80, achieving intelligent control and improving the adaptability and performance of the equipment.

[0046] In one embodiment, the heat-insulating cylinder 40 is made of mica, plastic, or glass.

[0047] Preferably, the heat-insulating cylinder 40 is made of mica material. Mica material itself has very low thermal conductivity, which can effectively prevent heat conduction. In electrical equipment, the heat-insulating cylinder 40 can isolate the heat generated by the heating element from other components, reducing the impact of heat on surrounding components. In addition, mica is an excellent insulating material with high insulation resistance and voltage withstand performance. In electrical equipment, the heat-insulating cylinder 40 can play a role in electrical insulation, preventing short circuits between the heating element and other metal parts, and ensuring the safe operation of the equipment.

[0048] In one embodiment, the protective cover 70 is made of metal, glass, or plastic material.

[0049] Specifically, metallic materials possess high strength and hardness, effectively resisting external mechanical impacts and collisions. Furthermore, metallic materials have high melting points and good heat resistance, remaining stable in high-temperature environments. The glass protective cover 70 has good transparency, allowing infrared radiation to pass through. Plastic materials generally have a much lower density than metals and glass, therefore the plastic protective cover 70 is lightweight, and the raw material cost of plastic materials is relatively low.

[0050] In one embodiment, the reflective cup 60 is made of a metallic material.

[0051] Specifically, metal materials inherently possess high reflectivity, which can be further enhanced through surface polishing and coating. Furthermore, metal materials exhibit high strength and hardness, enabling them to withstand certain mechanical impacts and pressures without easily deforming or being damaged. Compared to reflective cups 60 made of materials such as plastic, metal reflective cups 60 have a longer service life.

[0052] Specifically, the other structures of the host 10 adopt existing publicly available technologies, which will not be elaborated on here.

[0053] 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.
