    • 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).
    • 本发明提供一种吹风机(110),通过该吹风机(110),能够在轴向吹风方向上以小尺寸同时产生大风量和高风压。 本发明包括连接到驱动马达以使固定到旋转轴(11)上的圆柱形轮毂(12)旋转的旋转轴(11),螺旋地形成在轮毂(12)的外圆周上的至少一个叶片(13) )具有等于或小于轮毂(12)的半径的宽度,以及具有预定曲率半径的风扇壳体(15)以包围所述至少一个叶片(13)。 并且,本发明包括连接到驱动马达以旋转的旋转轴(11),固定到旋转轴(11)的圆柱形轮毂(12),以及螺旋形成在旋转轴(11)的外周上的至少一个叶片(13) 轮毂的宽度等于或小于轮毂(12)的半径。
