Wind acts on the second fan blade 23, so that the rotating rod 16 drives the rotating shaft 4 to rotate through the transmission mechanism, and further drives the rotor 5 to cut the magnetic induction lines generated by the stator 3, thereby generating current. In the rotating process of the rotating shaft 4, the first fan blade 6 draws the external air flow into the first housing 1 from the air inlet through hole 12, and under the guiding action of the second guiding plate 11 and the third guiding plate 8, the air flow enters the gap between the stator 3 and the rotor 5 to take out the heat, and the heat is discharged out of the first housing 1 from the air outlet through hole 13 under the guiding action of the first guiding plate 10.
