Automatic power recharging device for fan

The invention relates to an automatic power recharging device for a fan, and particularly relates to a device capable of recharging power and saving energy and electricity. The automatic power recharging device for the fan consists of a motor, a coil assembly, blades, a rectifier and a storage battery. The coil assembly is arranged at the front end of the motor of the fan, a plurality of coil columns are arranged on the coil assembly, and magnetic rings are arranged in the centers of the blades, are arranged on the axis of the motor and cover the coil columns. When the blades rotate, current is generated by magnetic force, so that the power can be recharged into the storage battery, the aims of saving energy and electricity are fulfilled, and the automatic power recharging device has high practicability. 本发明涉及一种风扇自动回充电力装置，特别是指一种可以回充电力，节能省电的装置。该风扇自动回充电力装置由马达、线圈组、叶片、整流器及蓄电池所组成。其主要是在风扇的马达前端安装线圈组，该线圈组上设有数个线圈柱，叶片中心内部设有磁圈，装设于马达的轴心并使磁圈覆盖于线圈柱，当叶片旋转时利用磁力产生电流，使电力能回充至蓄电池中，以达到节能省电的目的，具有相当的实用性。
