Description

Technical Field

[0001] This utility model relates to the field of hair care product technology, specifically to a multifunctional hair dryer comb. Background Technology

[0002] Traditional hair dryers can only be used to dry hair, and hair needs to be separated by hand or comb to dry the inner hair faster. Therefore, hair dryer combs have appeared on the market, which integrate the functions of hair dryer and comb. They can comb hair while drying, which is not only more convenient to use, but also more efficient and leaves hair smoother. However, the function of hair dryer combs is still relatively simple. Utility Model Content

[0003] The purpose of this invention is to provide a multifunctional hair dryer comb that is more efficient at drying hair.

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

[0005] A multifunctional hair dryer includes a handle and a comb body. The handle includes a tubular housing, a fan assembly disposed within the housing, and a first heating element disposed between the air outlet of the fan assembly and the comb body. The comb body includes an air guide shroud that connects to the air outlet of the tubular housing, a heat insulation shroud fixed to the bottom of the air guide shroud, and a metal plate embedded in the bottom of the heat insulation shroud. An air guide cavity is formed between the air guide shroud and the heat insulation shroud, and a heat insulation cavity is formed between the heat insulation shroud and the metal plate. A second heating element is installed on the top surface of the metal plate within the heat insulation cavity. The bottom surface of the metal plate is evenly distributed with downwardly extending metal heat-conducting comb teeth, and heat insulation comb teeth are installed on the metal plate, which are staggered with the heat-conducting comb teeth and whose bottom ends extend beyond the heat-conducting comb teeth. The heat insulation shroud has a vertically penetrating air outlet corresponding to the outer periphery of the heat insulation cavity, so that the air from the fan assembly is blown out towards the comb teeth after passing through the air guide cavity.

[0006] In a preferred embodiment, the air guide shroud has a central hole, such that the air guide cavity is an annular channel arranged around the circumference of the comb body.

[0007] In a preferred embodiment, the housing is further provided with a control circuit board located behind the fan assembly along the axial direction. The control circuit board includes a first plate located below and a second plate that is electrically connected and fixed above the first plate in parallel. The second plate is shorter than the first plate and is located at the rear of the first plate, while the front part of the first plate is located below the fan assembly.

[0008] In a preferred embodiment, the fan assembly includes a high-speed brushless motor, fan blades driven by the high-speed brushless motor, and a cylindrical fixing sleeve disposed outside the high-speed brushless motor and the fan blades.

[0009] In a preferred embodiment, the first heating component includes a cylindrical sheath that is connected to the front end of the fixed sleeve, a plurality of mica sheets disposed axially within the sheath, and an electric heating wire wound on the mica sheets, wherein the front end of the sheath communicates with the air guide cavity.

[0010] In a preferred embodiment, a negative ion generator is further provided behind the fan assembly within the handle.

[0011] In a preferred embodiment, the top surface of the metal plate is formed with a plurality of grooves, and a fixing strip is embedded in the grooves, while the heat-insulating comb teeth are formed on the fixing strips.

[0012] In a preferred embodiment, the second heating component includes a heat-conducting plate fixed to the top surface of the metal plate, a mounting cavity formed on the heat-conducting plate, and a PTC heating element and an NTC temperature sensor disposed within the mounting cavity.

[0013] The beneficial effects of this utility model are as follows: When quick hair drying is required, the fan assembly is activated, and the first heating assembly and the second heating assembly are turned on simultaneously. High-speed air is heated by the first heating assembly and blown out from the air outlet on the comb teeth. At the same time, the heat-conducting comb teeth heat the roots of the hair that are most difficult to dry while combing and separating the hair, so that the hair can be dried quickly. Compared with ordinary combs, the hair drying efficiency is higher. When the first heating assembly is turned off, the fan assembly blows out natural cool air from the air outlet, and the heat-conducting comb teeth heat the hair to soften it. When the heated and softened hair encounters the cool air blown out from the edge of the comb body, it can be quickly cooled and styled, so it can be used for straightening hair or assisting in styling hair.

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] refer to Figures 1 to 6 This embodiment of a multifunctional hair dryer includes a handle 1 and a comb body 2. The handle 1 includes a housing 11, a fan assembly 12 disposed within the housing 11, and a first heating element 13 disposed between the air outlet of the fan assembly 12 and the comb body 2. The comb body 2 includes an air guide shroud 21 that connects to the air outlet of the housing 11, a heat insulation shroud 22 fixed to the bottom of the air guide shroud 21, and a metal plate 23 embedded in the bottom of the heat insulation shroud 22. An air guide cavity is formed between the air guide shroud 21 and the heat insulation shroud 22. A heat insulation cavity is formed between the heat shield 22 and the metal plate 23. A second heating component 24 is installed on the top surface of the metal plate 23 inside the heat insulation cavity. The bottom surface of the metal plate 23 is evenly distributed with downwardly extending metal heat-conducting comb teeth 231. Heat-insulating comb teeth 25 are installed on the metal plate 23, which are staggered with the heat-conducting comb teeth 231 and whose bottom ends extend beyond the heat-conducting comb teeth 231. The heat shield 22 is provided with a vertically penetrating air outlet 221 corresponding to the outer periphery of the heat insulation cavity, so that the air from the fan assembly 12 is blown out towards the comb tooth surface after passing through the air guide cavity.

[0023] During operation, the fan assembly 12 operates, allowing natural air to pass through the first heating assembly 13 into the air guide hood 21 and be blown out from the air outlet 221 around the heat insulation hood 22; while the metal plate 23 and the heat-conducting comb teeth 231 are heated by the second heating assembly 24 to heat the hair while combing it, and the heat-insulating comb teeth 25 are used to prevent the heat-conducting comb teeth 231 from burning the scalp. When quick hair drying is needed, the blower assembly 12 is activated, and the first heating assembly 13 and the second heating assembly 24 are turned on simultaneously. High-speed air is heated by the first heating assembly 13 and blown out from the air outlet 221 on the comb teeth. At the same time, the heat-conducting comb teeth 231 heat the roots of the hair that are most difficult to dry while combing and separating the hair, so that the hair can be dried quickly. Compared with ordinary combs, the hair drying efficiency is higher. When the first heating assembly 13 is turned off, the blower assembly 12 blows out natural cool air from the air outlet 221, while the heat-conducting comb teeth 231 heat the hair to soften it. When the heated and softened hair encounters the cool air blown out from the edge of the comb body 2, it can be quickly cooled and styled, so that it can be used to straighten hair or assist in styling hair.

[0024] In a preferred embodiment, the air guide shroud 21 has a central hole 211, making the air guide cavity an annular channel arranged around the comb body 2. The central hole 211 ensures that the airflow from the blower assembly 12 does not blow towards the center of the heat shield 22 when passing through the air guide cavity. Since the center of the heat shield 22 is directly below the second heating element 24, the cool air passing through the air guide cavity will not interfere with the heat of the second heating element 24 when used for straightening or styling. Furthermore, the central hole 211 increases the airflow pressure through the air guide cavity, resulting in a stronger airflow from the air outlet 221.

[0025] In a preferred embodiment, the housing 11 of this embodiment also includes a control circuit board 14 located axially behind the fan assembly 12. The control circuit board 14 includes a first plate 141 located below, and a second plate 142 electrically connected and fixed above the first plate 141. The second plate 142 is shorter than the first plate 141 and located at the rear of the first plate 141, while the front portion of the first plate 141 is located below the fan assembly 12. The control circuit board 14 is arranged in two staggered positions, which can significantly reduce the length of the handle 1, making the structure more compact.

[0026] In a preferred embodiment, the fan assembly 12 includes a high-speed brushless motor 121, fan blades driven by the high-speed brushless motor 121, and a cylindrical fixing sleeve 122 disposed outside the high-speed brushless motor 121 and the fan blades. The fixing sleeve 122 not only mounts and fixes the high-speed brushless motor 121, but also makes the airflow from the fan assembly 12 more concentrated and directed towards the front end.

[0027] In a preferred embodiment, the first heating component 13 includes a cylindrical sheath 131 that abuts against the front end of the fixing sleeve 122, a plurality of mica sheets 132 axially disposed within the sheath 131, and heating wires wound around the mica sheets 132. The front end of the sheath 131 communicates with the air guide cavity. The sheath 131 not only serves as heat insulation but also allows the air from the fan assembly 12 to be blown more concentratedly into the air guide cavity.

[0028] In a preferred embodiment, a negative ion generator 15 is further provided behind the fan assembly 12 inside the handle 1.

[0029] In a preferred embodiment, the top surface of the metal plate 23 is formed with a plurality of grooves 232, and a fixing strip 251 is embedded in the grooves 232, while the heat-insulating comb teeth 25 are formed on the fixing strip 251.

[0030] In a preferred embodiment, the second heating component 24 includes a heat-conducting plate 241 fixed to the top surface of the metal plate 23, a mounting cavity formed on the heat-conducting plate 241, and a PTC heating element 242 and an NTC temperature sensor 243 disposed in the mounting cavity.

[0031] The above description does not limit the technical scope of this utility model. Any modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of this utility model shall still fall within the scope of the technical solution of this utility model.
