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.

Abstract: An electrode panel-drawing device of a static ion discharger, including a box body. A top section of the box body is formed with an opening. A bottom section of the box body is disposed with a connecting seat. The box body is disposed with ventilators, an activating switch and an adjustment button. A motor, a fan and an AC-to-DC circuit board are disposed in the box body. A drawer body is fitted into the opening of the box body. The drawer body is disposed with discharge needles and electrode panels at equal intervals. The positive terminal of the circuit board is connected to the discharge needles, while the negative terminal of the circuit board is connected to the electrode panels. The positive discharge needles ionize the air to eliminate the static electricity. The drawer body can be drawn out of the box body for directly washing the discharge needles and the electrode panels.
