Abstract
A hair dryer includes an air outlet portion, a holding portion, a start switch, an airflow rate control switch, an airflow rate indication portion, an input power control switch, and an input power indication portion. Thus, when the user presses the start switch, the hair dryer will start to perform with its previous setting in memory for the airflow rate and its power input. And when the user presses the airflow rate control switch or the input power control switch, the system enters the manual control mode, and is forced into the safety mode immediately, so that the user can adjust the input power and the airflow rate according to the preset safety values, thereby achieving the safe requirement.
