Abstract

A blower includes an axial fan for generating airflow. The axial fan includes a center hub capable of rotating around a central axis and several blades extended outward from the center hub in a radial direction and arranged around the central axis. The several blades and the center hub are integrated as a whole. Each blade is provided with a suction surface and a pressure surface for generating airflow. Two opposite ends of the suction surface and a pressure surface are intersected to form a front edge and a rear edge, and the front edge is in the front of the rear edge in a rotation direction of the axial fan. The front edge has a point close to the center hub which is defined as a root point, and the front edge has another point far from to the center hub which is defined as a tip point.
