Abstract
In accordance with the present invention, there is provided an air purification device including: a first electrode in the shape of a hollow cylinder having both ends open; a second electrode in the shape of a solid needle having a tip end portion of a predetermined length including a pointed tip; a dielectric member covering the second electrode except the tip end portion; and a power supply for applying a high voltage across the two electrodes in order to create a corona discharge, for generating ozone and ion wind. The dielectric material may be of any type of silicone or plastic (including epoxy) as long as it is inexpensive and easy to mold. The dielectric member is, for example, in the shape of a circular flange, providing ease of maintenance and safety measures as well as permitting effective airflow.
