According to an embodiment of the present invention, a hair dryer 25 is provided as shown in FIG. 1 to FIG. 2 . The embodiment of the present application provides a hair dryer 25 . The hair dryer 25 includes: a first shell 6 in the shape of a bar; A first air outlet 1 and a first air inlet 4 at the upper and lower ends of a housing 6, a first air duct 7 communicating with the first air inlet 4 and the first air outlet 1 is arranged in the first housing 6, and the first air A motor group 3 and a heating wire group 2 are arranged in the duct 7 in sequence; there is an installation gap 17 between the outside of the first air duct 7 and the inside of the first housing 6, and a PCB control board 20 is arranged in the installation gap 17, and the PCB control board 20 One side is fixed on the first casing 6 , and the other side is arranged close to the first air duct 7 .

In this embodiment, the first housing 6 is in the shape of a bar, preferably a cylindrical shape, which is convenient for users to hold. The first air outlet 1 and the first air inlet 4 are respectively opened at the upper and lower ends of the first housing 6. The duct 7 communicates with the first air inlet 4 and the first air outlet 1 and is located in the first casing 6. The first air duct 7 is formed by at least one arc-shaped plate fixed in the first casing 6. The unit 3 is installed in the first air duct 7 in an up and down sequence. The motor unit 3 is composed of a fan blade and a driving motor unit 3. The fan blade is driven to rotate by the driving motor, so that the external air is sucked into the first air duct 7 from the air inlet to form a wind. , the air flows out from the first air outlet 1 after being heated by the heating wire group 2, the first air duct 7 is arranged in a straight line in the longitudinal direction, and an installation gap is reserved between the first air duct 7 and the inside of the first housing 6 17, that is, the installation gap 17 is also linear, and the PCB control board 20 is longitudinally fixed in the installation gap 17 in a long strip shape, and is electrically connected with the motor group 3 and the heating wire group 2. Since a plurality of components of different types and sizes are mounted on the PCB control board 20, the shape of the installation gap 17 should be consistent with the overall shape of the PCB control board 20, so that the size of the installation gap 17 is small enough, and the PCB control board 20 After installation, it is closely attached to the first air duct 7, which makes the product smaller in size and convenient for storage and carrying without affecting too much wind speed and air volume. There are problems that the internal structure layout is relatively scattered, which affects the wind speed and air output, and the structure is complex and inconvenient for storage and carrying.
