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.

Abstract: A massaging device includes a plurality of pebble-shaped massaging media which directly touch and surround the user's two feet. Thus, the pebble-shaped massaging media directly touch the user's two feet, so that the vibration force are fully and thoroughly transmitted to the user's two feet through the pebble-shaped massaging media, thereby enhancing the massaging effect for the user's two feet. In addition, the pebble-shaped massaging media are freely moving and rolling around the user's feet during container vibrating that provides a great massaging feeling to the user.

Abstract: A hair roller assembly includes a cover made of a soft elastomer material having an inner wall formed with an inner space, and a sponge unit mounted in the inner space of the cover. The cover has a determined length with different sizes. The sponge unit includes a first sponge, a second sponge and a third sponge having different shapes, diameters and density, so that the soft cover mounted on the sponge unit presents different shapes and sizes, and the user's hair curled around the cover also presents different shapes and styles, thereby enhancing variation of the styles of the user's hair.
