Although the type, style and size of the hair dryer are very different, but their internal structure is basically the same, mainly by the motor and its driving wind blade, heating components and electrical control switch components of three parts, the product structure is relatively simple. When the hair dryer is energized, the electric heating wire will generate heat, and the wind blown by the fan will pass through the electric heating wire and become hot air. If only the small fan rotates, and the electric heating wire is not hot, then the wind that blows out is just equivalent to room temperature.
