[0079] Specifically, the third shell 213 includes a mounting wall 2131 and a mounting shell 2132, the mounting wall 2131 is arranged below the second air duct 2130 and opposite to the middle of the axial length of the second shell 212, and the mounting shell 2132 is axially parallel to the second shell 212. The heating wire 31 of the heating wire assembly 3 is aligned with the mounting wall 2131 away from one end of the first air outlet 20.

The projection of the third shell 213 in the third air duct is the longitudinal section of the third shell 213, and the total projection of the third air duct is the longitudinal section of the second shell 212. When the area of the third shell 213 accounts for 30-60% of the total area of the third air duct, a better balance is achieved between the installation space effect of the third shell 213 and the auxiliary flow effect of the second air duct 2130.

[0117] Embodiment five:

[0118] At present, the heating wire assembly in the high-speed hair dryer is usually formed by an inner shell and a plurality of supporting sheets inserted outside the inner shell to form a supporting frame, and the heating wire is arranged in a ring shape outside the supporting frame. In order to ensure the safety of the use of the high-speed hair dryer, a temperature controller also needs to be arranged in the air duct of the hair dryer. However, the temperature controller in the current high-speed hair dryer is generally arranged at one end of the heating wire assembly close to the first air outlet of the high-speed hair dryer. On the one hand, the temperature controller will interfere with the airflow, causing turbulence after the airflow passes through the temperature controller, affecting the flow rate of the airflow after blowing out of the first air outlet, and also increasing the airflow noise. On the other hand, the temperature controller can be seen from the first air outlet, affecting the overall appearance of the hair dryer and reducing the user's experience.

[0120] Specifically, the wind generating assembly in the handle 12 includes a motor and an impeller, and the motor is preferably a brushless high-speed motor. In one embodiment, the tail of the handle 12 is the air inlet of the whole hair dryer, and after the airflow enters the handle 12 from the tail of the handle 12, it is introduced into the first air inlet 201 of the air duct 11 along the airflow channel in the handle 12, and then the airflow enters the air duct 11 from the first air inlet 201 of the air duct 11, passes through the heating of the heating wire assembly, and finally blows out from the first air outlet 20 of the air duct 11.

[0121] It should be noted that the second heat shield 5 is made of high-temperature-resistant, insulating and heat-insulating material, and the material of the second heat shield 5 is preferably mica sheet, and in other embodiments, the second heat shield 5 can also be made of porous ceramic or ceramic-based heat-insulating material. The temperature controller 301 is preferably a snap-action temperature controller 301, which has simple structure, stable performance, long service life and is not easy to be damaged.
