Abstract:
The present invention relates to an electric hair dryer air channel structure, comprising a columnar air channel shell (1) and an arc-shaped flow guide grid (2). A vertical air cavity (3) is provided inside the columnar air channel shell (1), an air inlet (4) in communication with the vertical air cavity (3) is provided at the bottom of the columnar air channel shell (1), and a horizontal air outlet (5) in communication with the vertical air cavity (3) is provided in a side wall of the columnar air channel shell (1), an arc transition being used to connect the vertical air cavity (3) and the horizontal air outlet (5). One end of the arc-shaped flow guide grid (2) is mounted on an inner wall of the vertical air cavity (3), and the other end of the arc-shaped flow guide grid (2) is mounted on an inner wall of the horizontal air outlet (5). By means of the arc-shaped flow guide grid (2), vertical flowing air sucked into the vertical air cavity (3) via the air inlet (4) is adjusted to become horizontal flowing air expelled from the horizontal air outlet (5). The invention has the advantages of a small volume, high blowing speed, large air volume and a moderate air output angle.
