摘要：
The present invention provides a blowing fan (110), by which both high wind amount and high wind pressure can be simultaneously generated with a small size in an axial blowing direction. The present invention includes a rotational shaft (11) connected to a drive motor to rotate a cylindrical hub (12) fixed to the rotational shaft (11), at least one blade (13) spirally formed on an outer circumference of the hub (12) to have a width equal to or smaller than a radius of the hub (12), and a fan housing (15) having a predetermined curvature radius to enclose the at least one blade (13). And, the present invention includes a rotational shaft (11) connected to a drive motor to rotate, a cylindrical hub (12) fixed to the rotational shaft (11), and at least one blade (13) spirally formed on an outer circumference of the hub to have a width equal to or smaller than a radius of the hub (12).
