Abstract
A fan system is electrically connected with a driving source generator and includes a first fan, a second fan and an energy storage element. The second fan is rotated by the first fan for generating an electric energy. The energy storage element is electrically connected with the second fan for storing the electric energy and keep supplying power when the driving source generator is out of order or the fan is rotating in lower rotation speed.
Claims21
A fan system, comprising:
- a first fan having a motor which is electrically connected with a driving source generator, wherein the motor of the first fan is driven by the driving source generator;
- a second fan having a motor which is induced for generating an electric energy by the first fan;
- and
- an energy storage element having an input terminal and two output terminals, wherein the input terminal is electrically connected with the second fan for storing the electric energy therein, and the output terminals are electrically connected with the first fan and the second fan, respectively.
