[0002] A hair dryer can be used to quickly dry hair and style hair, and is one of the essential household appliances in modern life. The common hair dryer looks very much like a "T" or "7" shape, that is, it consists of two major units: a handle + a main body, and the handle unit is either foldable or non-foldable. This structure causes the hair dryer to be large in size, making it extremely inconvenient to carry. If the above two major units are combined into one, the size of the hair dryer will be greatly reduced. In order to reduce the size of the hair dryer, if the above handle + main body units are combined into one, the design of the air duct structure, the position of the air inlet and the air outlet are not on the same line, which greatly reduces the loss of air volume and air pressure, forming a new problem.
