摘要： A heat-dissipating fan having a dust-proof structure includes a stator and a rotor. The stator includes a shaft and a bearing disposed in a shaft hole of the shaft. The rotor includes an axle inserted in the bearing. The axle of the rotor has an inner end connected with an axle seat. The axle seat is located in the shaft hole of the shaft. A slight gap is defined between an outer wall of the axle seat and an inner wall of the shaft hole. The outer wall of the axle seat has a plurality of guiding grooves to block external air from entering the bearing. The guiding grooves are spiral grooves or V-shaped grooves. The guiding grooves are used to expel the air along with the rotation of the rotor, achieving a dust-proof protective structure in a non-contact type to block external dust or water vapor from entering the bearing to influence the running of the bearing. The present invention can enhance the service life of the heat-dissipating fan.

摘要翻译： 具有防尘结构的散热风扇包括定子和转子。 定子包括轴和设置在轴的轴孔中的轴承。 转子包括插入轴承中的轴。 转子轴具有与轴座连接的内端。 轴座位于轴的轴孔中。 在轴座的外壁和轴孔的内壁之间限定了微小的间隙。 轴座的外壁具有多个导向槽，以阻止外部空气进入轴承。 导向槽是螺旋槽或V形槽。 引导槽用于与转子的旋转一起排出空气，实现非接触式的防尘保护结构，以阻止外部灰尘或水蒸汽进入轴承，从而影响轴承的运行。 本发明可以提高散热风扇的使用寿命。
