Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of hair dryers and straighteners, specifically a styling device that combines hot air drying and hair straightener heating functions, and is especially suitable for an integrated device that dries hair quickly and completes hair straightening simultaneously. Background Technology
[0002] Traditional hair straighteners typically require separate use after hair is blow-dried, a cumbersome process. Furthermore, the single heating plate often results in uneven heat distribution, necessitating repeated straightening and potentially damaging the hair. While some hair straightener-dryer combos exist (such as Dyson), their primary function remains blow-drying, with insufficient heating efficiency in the straightening module, limiting styling results. Therefore, achieving a seamless transition between efficient hot air drying and precise straightening, while minimizing heat damage, remains a key technical challenge. Utility Model Content
[0003] The purpose of this utility model is to provide a device that integrates hot air drying and secondary styling functions with dual heated aluminum plates. Through the synergistic effect of hot air preheating and instantaneous pressure on the aluminum plates, the styling time is shortened, smoothness is improved, and hair damage is reduced.
[0004] To achieve the above objectives, this utility model is implemented through the following technical solution: a hair dryer with a design that combines hot air and dual heating aluminum plates, comprising a housing, a control board inside the housing, a fan installed inside the housing, an air inlet assembly at the bottom of the housing for air intake by the fan, a Y-shaped air duct at the top of the housing, with one outlet of the Y-shaped air duct pointing towards the air outlet of the fan, and both outlets of the Y-shaped air duct pointing away from the housing, a connecting shaft fixedly connected to the inner wall of the housing at the middle of the Y-shaped air duct, two inner shells hinged to the connecting shaft, the two inner shells being symmetrical and their outer walls facing each other, a sealing shell fixedly connected to the inner side of the inner shell, the fan being able to blow air between the inner shell and the sealing shell through the Y-shaped air duct, an outer shell fixedly connected to the outer side of the sealing shell, and the edge of the outer shell wrapping around the edge of the inner shell.
[0005] A partition strip is fixedly connected to the inner wall of the inner shell. The opening of the partition strip is connected to the Y-shaped air guide pipe. A heating component is installed on the inner wall of the inner shell and inside the partition strip. An air outlet is opened on the inner wall of the inner shell and inside the partition strip. The airflow blown into the inner shell by the fan through the Y-shaped air guide pipe is heated by the heating component and then discharged through the air outlet.
[0006] A U-shaped aluminum plate is fixedly connected to the outer wall of the inner shell and recessed outside the partition strip. The bottom walls of the U-shaped aluminum plates on the two inner shells are in contact. A second heating component is provided inside the U-shaped aluminum plate. The first heating component and the second heating component are arranged in parallel.
[0007] Preferably, the heating assembly includes a heating wire, a temperature sensor, a fuse, and a wire frame. The heating wire is mounted on the wire frame on the inner wall of the inner shell, and the fuse is mounted on the heating wire. The temperature sensor is also mounted on the inner shell near the heating wire for temperature monitoring.
[0008] Preferably, the second heating component includes a ceramic heating element, a second temperature sensor, and a second fuse. The ceramic heating element is embedded in a U-shaped aluminum plate, and the second fuse is installed on the circuit of the ceramic heating element. The second temperature sensor is installed in the U-shaped aluminum plate for temperature monitoring.
[0009] Preferably, the heating wires and the ceramic heating element are both connected to the control board through a Y-shaped air duct.
[0010] Preferably, two mica heat insulation sheets are also fixedly connected to the wire frame. The two mica heat insulation sheets are located on the inner and outer sides of the heating wire, respectively, to isolate the heat transferred from the heating wire to the inner shell and the sealing shell.
[0011] Preferably, the bottom of the U-shaped aluminum plate is covered with a PPS heat insulation layer.
[0012] Preferably, the air outlet is located on the bottom wall of the inner shell, with the opening pointing away from the U-shaped aluminum plate, and the air outlet trajectory on the bottom wall of the inner shell is designed in a streamlined manner.
[0013] Preferably, the outer shell edge is provided with air holes at the position corresponding to the air outlet, and the outer shell outer wall edge is provided with comb teeth at the position corresponding to the air outlet.
[0014] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:
[0015] This hair dryer and straightener features a design that combines hot air and dual heating aluminum plates. The technical solution uses a dual-heating U-shaped aluminum plate as the heat source, which, together with the hot air heated by the heating components, works in a sequential linkage. This allows the hot air to pre-soften the hair, and then the U-shaped aluminum plate closes to apply heat and pressure, achieving high-temperature and rapid styling of the hair.
[0016] Furthermore, the hot air temperature is lower than that of the U-shaped aluminum plate, forming a stepped heating process of "softening first and then shaping," which avoids damage to the hair caused by concentrated high temperature.
[0017] The design of the temperature sensor enables independent temperature control of heating component one and heating component two, achieving independent control of the hot air and U-shaped aluminum plate temperature, allowing for adaptive selection for different hair types and reducing the risk of hair damage.

[0031] A U-shaped aluminum plate 13 is fixedly connected to the outer wall of the inner shell 7 and is recessed outside the partition strip 10. The bottom walls of the U-shaped aluminum plates 13 on the two inner shells 7 are in contact. A second heating component 14 is provided inside the U-shaped aluminum plate 13.
