Abstract
An ion wind generating device includes a high voltage power supply, a capacitor connected in parallel to the high voltage power supply, a first metal cone connected in series to the high voltage power supply, a ground plate disposed on the same axis as the first metal cone, a starter motor, and a second metal cone disposed on a connecting shaft. The starter motor includes a rotating shaft and a connecting shaft perpendicular to the rotating shaft. After second metal cone moves to be located between first cone and the ground plate, the starter motor stops rotating. The high voltage power supply charges the capacitor with the high voltage power, and the capacitor discharges the first metal cone. When the second metal cone is located between the first metal cone and the ground plate, the first metal cone causes the second metal cone to discharge to generate an ionic wind.
