What's the difference between a wall-mounted hair dryer and an ordinary hair dryer?

The difference between wall-mounted hair dryer and ordinary hair dryer is that wall-mounted hair dryer is generally a touch switch, which starts when the hand is pressed and stops when the hand leaves. For example, the wall-mounted hair dryer produced by Fengjie Sanitary Ware is a touch switch, with overheating protection and wavy heating wire. Personally, I think it would be better for people who are forgetful to use a wall-mounted hair dryer.
