In addition, the heating power of the heating wire 83 can also be adjusted by operating the second control switch 317 to meet the user's requirements for hot air flows with different temperatures.

In the using process of the wireless hair dryer 100, because a part of the airflow flowing into the air outlet channel 201 from the air inlet channel 301 passes through the rechargeable battery 51 and the main control board 56, the heat generated by the rechargeable battery 51 and the main control board 56 during operation is dissipated in time by the airflow flowing into the air outlet channel 201 from the air inlet channel 301, so that the wireless hair dryer 100 is more stable in operation, the rechargeable battery 51 and the main control board 56 can be prevented from being damaged due to overhigh temperature, and the service life of the wireless hair dryer 100 is prolonged.

Preferably, the main control board 56 is further provided with a battery protection circuit module, which is used for effectively protecting the rechargeable battery 51 in the machine body 20, i.e. preventing overcharge protection, over-discharge protection, over-current protection, short-circuit protection and the like of the rechargeable battery 51.

Preferably, the wireless hair dryer 100 is further provided with a display module electrically connected to the main control board 56, the display module is used for displaying the working state of the wireless hair dryer 100, and a user can know the working state of the wireless hair dryer 100 in time by observing the display module.

In other embodiments, the main housing 21 may also be a rectangular cavity, an oval cavity, a polygonal cavity, etc.

The foregoing is illustrative of embodiments of the present invention, and it should be noted that modifications and adaptations to those skilled in the art may be made without departing from the principles of the embodiments of the present invention and are intended to be within the scope of the present invention.
