  Further, the angle formed by the center line of the toggle hole 101 and the vertical direction is 18 ° to 22 °. In the present embodiment, this configuration allows the main shaft of the fan power head 300 to be swung to a position close to horizontal and directly sprayed on the human body without the toggle hole 101 interfering with the lever 810. Further, the angle formed by the center line of the toggle hole 101 and the vertical direction is 20 °, and the main axis of the fan power head 300 is swung to a horizontal position.

  Further, referring to FIG. 2, the angle β formed by the axis of the lever 810 and the axis of the fan power head 300 is 22 ° to 28 °. In the present embodiment, the main axis of the fan power head 300 is swung up to near the vertical direction based on the fact that the angle formed by the center line of the toggle hole 101 and the vertical direction is 18 ° to 22 °. Therefore, it is possible to blow the fan power head 300 almost vertically upward and almost horizontally, thereby realizing three-dimensional blowing. Specifically, the angle formed by the center line of the toggle hole 101 and the vertical direction is 20 °, and the angle formed by the axis of the lever 810 and the axis of the fan power head 300 is 25 °.
