Abstract:
An exhaust blower comprises an exhaust cover (1) and an electric fan (2) connected fixedly on the inner side of the exhaust cover (1). A direct current generator (3), an illuminating lamp (4) and an accumulator (5) which are electrically connected in series are arranged on the exhaust blower. A solar energy receiver is disposed at a place where the accumulator (5) and the direct current generator (3) are located. The solar energy receiver is connected electrically with the accumulator (5). The direct current generator (3) coaxial with the motor of the electric fan (2) is connected fixedly on a main shaft of the electric fan (2). The exhaust blower illuminates by LED with direct current power and the accumulator is charged by the direct current generator driven by the electric fan. The exhaust blower is energy-saving, safe and has prolonged service life. When the fan runs, a solar energy board and battery control device thereof can supply power excellently for the exhaust blower and the LED, and while the fan stops working, the solar energy board can charge the accumulator so as to save energy.
