<p>PROBLEM TO BE SOLVED: To generate and store electric energy using mechanical energy generated by rotation of an electric fan and recycle, save, and store the energy generated by the electric fan.SOLUTION: An electric fan device includes: a blower unit 10; a power generator unit 18; and at least one energy storage unit 28. A DC motor 12 penetrated by a first shaft 14 is provided in the blower unit 10, and connecting one end of the first shaft 14 to blades 16 of the blower unit 10 enables the DC motor 12 to drive the first shaft 14 to rotate the blades 16. An installation member 142 for installing the power generator unit 18 is provided on the other end of the first shaft 14. The power generator unit 18 includes a three-phase electric generation coil 22 penetrated by the installation member 142 and attached to a sidewall of the DC motor 12; and a magnet ring surrounding the three-phase electric generation coil 22. If the first shaft 14 rotates, the magnet ring 24 is interlocked with the rotation, so that magnetic induction occurs in the three-phase electric generation coil 22 to induce an alternating electromotive force. The alternating electromotive force is fed to the at least one energy storage unit 28, which converts the alternating electromotive force to electric energy and stores the electric energy.</p> |
