Abstract
Abstract An air-ionizing and deozonizing electrode block is fixed at the center of an insulating shell. The electrode block is made of a material containing manganese dioxide or copper oxide. The electrode block has many uniformly distributed perforations parallel to the axis of the insulating shell. Each perforation contains a conductive needle with its end bent 90° and fixed on the rear of the electrode block by conductive material. The point of the conductive needle in the central perforation of the electrode block projects from the front surface of the deozonizing block; the rest are within their perforation. The electrode block both generates negative ions in high concentration and clears ozone when high voltage of negative DC 10 KV-100 KV is applied.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
163 words
An electrode for producing a high concentration of negative ions in air and, at the same time, clearing ozone therefrom, comprising: a cylindric insulating shell (1); a cylindric electrode block (2) inside the insulating shell, the electrode block having perforations (5) therethrough between front and rear surfaces of the electrode block, one of the perforations being central of the electrode block; a conductive needle (3a, 3b) in each perforation, one end of each needle being pointed and the other end of each needle being bent about 90° to the axis of the needle and fixed to the rear surface of the electrode block for the needle to project along the axis of one of the perforations, the point of the needle in the central perforation so projecting from the front surface of the electrode block, the needle in each other perforation so projecting only within the perforation in which it projects; and a high tension lead wire (4) connected to the electrode block.
Claim 2
Dependent Claim
