The existence of the control component introduces an intelligent control system for the hair dryer. Users can use this component to easily adjust various parameters, such as wind speed, temperature, etc., which improves the personalization and convenience of use.

[0006] In one embodiment, the air duct assembly is provided with a third air outlet connecting the first channel and the second channel, and the third air outlet is spaced apart from the second air outlet.
