ABSTRACT:
A discharge electrode structure which is a substantially II-shaped sheet unit integrally made from one single blank sheet. The discharge electrode sheet unit includes two conductive sections connected with each other by two bridge sections at two ends. Two sides of each bridge section are formed with screw holes. Each conductive section is formed with a middle transverse bar formed with multiple perpendicular discharge needles at equal intervals. Each discharge needle has a tip. After the discharge electrode is connected with a DC high voltage power supply, free electrons are produced by discharging. The tips of the discharge needles are perpendicularly arranged at equal intervals so that ionic equilibrium can be easily achieved.
