[0002] With the improvement of living standards, people's demand for personal care products is increasing, especially for quick hair drying and styling. Traditional hair dryers generate hot air through simple heating elements, which can meet basic drying needs, but are insufficient in terms of temperature control, airflow adjustment, and minimizing hair damage. In recent years, to improve user experience and protect hair health, various improved hair dryer combs have emerged on the market, such as negative ion hair dryers and ceramic-coated heaters. This utility model relates to a hot air comb based on duct heating, aiming to solve the problems of uneven temperature, large heat loss, and heat damage to hair caused by existing hair dryers. This hot air comb adopts a unique duct design, optimizing airflow path and heating method to achieve more uniform temperature distribution and higher energy efficiency. Combined with an intelligent temperature control system, it ensures a suitable temperature in different usage scenarios, effectively reducing hair damage and improving the user experience. Furthermore, this hot air comb integrates a comb function, allowing users to easily style their hair while drying, meeting the needs of modern people for an efficient and convenient lifestyle.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A hot air comb based on duct heating includes a comb body assembly and a hot air assembly. The comb body assembly includes a comb handle side cover, a sealing strip, and a limiting end cover. The sealing strip is snapped between the comb handle side covers. A switch guard ring is installed on the outer side of the comb handle side cover. A dustproof end cover is snapped onto one end of the comb handle side cover, and a comb tooth plate is snapped onto the other end. An air outlet is opened on the comb tooth plate. A heat insulation cover is fixed on the outer side of the comb tooth plate. One end of the comb tooth plate is threadedly connected to the limiting end cover. The hot air assembly includes a temperature control module. From bottom to top, the temperature control module, an air guide cavity, and an air duct are sequentially snapped onto the inner side of one end of the comb handle side cover. A power cord is provided on the temperature control module. A motor is provided in the air guide cavity. A fan blade is installed on the motor, and the motor is electrically connected to the temperature control module. A heat-conducting plate is fixed in the air duct. A thermal resistance wire is provided on the heat-conducting plate, and the thermal resistance wire is electrically connected to the temperature control module.

[0006] Furthermore, both the comb handle side cover and the sealing strip are made of heat-insulating materials, effectively isolating the heat generated by the hot air assembly, preventing the hands from feeling high temperatures, and improving user comfort.

[0007] Furthermore, a filter screen is installed inside the dustproof end cover to effectively prevent dust from entering the hot air assembly, extend its service life, and maintain cleanliness and hygiene.

[0008] Furthermore, the sides of the heat-conducting plates are all serrated, which increases the heat exchange area and improves the uniformity of hot air and the accuracy of temperature control.

[0009] Furthermore, the comb teeth on the comb plate are arranged with varying spacing to accommodate different types of hair, reduce pulling and tangling, and improve combing effectiveness.

[0010] Furthermore, the air outlets are arranged in an elliptical shape to ensure that hot air is evenly distributed throughout the comb area, improving drying efficiency and avoiding localized overheating.

[0011] Compared with existing hot air combs based on duct heating, this invention has at least the following advantages:

[0012] 1. Precise temperature control: Through the cooperation of temperature control module and thermal resistance wire, the temperature of hot air is precisely controlled to avoid damage to the hair due to overheating.

[0013] 2. Uniform airflow distribution: The design of the air guide cavity and heat conduction plate ensures that hot air is evenly distributed throughout the comb tooth area, improving drying efficiency.

[0014] 3. Reasonable comb design: The comb teeth are arranged with varying spacing to accommodate different hair types and reduce pulling and tangling.

[0015] 4. Excellent dustproof performance: A filter screen is installed inside the dustproof end cap to effectively prevent dust from entering and extend service life.

[0016] 5. Excellent heat insulation performance: The comb handle side cover and sealing strip are made of heat insulation material, so the hands are not easily exposed to high temperatures, improving the comfort of use. Attached Figure Description
