    • Fan including a rotation shaft (1) rotatably coupled to a driving motor, a cylindrical hub (2) fixed to the rotation shaft (1), a plurality of helical blades (3) on an outside circumferential surface of the hub (2), and partition lines (5) each connecting a top end (3b) of the blade to a bottom end (3a) of an adjacent blade formed in the outside circumferential surface at a time of injection molding with molds, or alternatively, a fan including a rotation shaft rotatably coupled to a driving motor, a cylindrical hub (2) fixed to the rotation shaft (1), a plurality of helical blades (3) formed on an outside circumferential surface of the hub (2) such that the blades (3) do not overlap with one another when the blades are seen from a direction of the rotation shaft, thereby providing a fan which is easy to fabricate favorable for mass production, has a high air flow rate and a high air pressure, and an axial air flow direction.
    • 风扇包括可旋转地联接到驱动电动机的旋转轴(1),固定到旋转轴(1)的圆柱形毂(2),在轮毂(2)的外圆周表面上的多个螺旋叶片(3) 以及分隔线(5),每个分隔线(5)在注射成型模具时将叶片的顶端(3b)连接到形成在外圆周表面中的相邻叶片的底端(3a),或者替代地,包括 可旋转地联接到驱动电动机的旋转轴,固定到旋转轴(1)的圆柱形轮毂(2),形成在轮毂(2)的外圆周表面上的多个螺旋叶片(3),使得叶片(3) )在从旋转轴的方向观察叶片时彼此不重叠,从而提供容易制造的风扇,其有利于批量生产,具有高空气流速和高气压,以及轴向空气 流动方向。
