Patent ID: 7855868

Claim:
An aerosol charge neutralizer comprising: an aerosol flowing container having an aerosol input port at an upstream end, an aerosol output port at a downstream end, a tubular body made of conductive material and constituting an aerosol flow path capable of flowing aerosol, and an opening pair having a pair of openings disposed facing each other via a center line of said tubular body, each opening extending through a wall of said tubular body; an insulating tube having a tubular portion made of insulating material and a window pair having a pair of windows disposed facing each other via the center line of said tubular portion, each window extending through a wall of said tubular portion, and said insulating tube being concentrically engaged with an outer surface of said aerosol flowing container in such a manner that said window becomes coincident in position with said opening; a bipolar ion generator element having a discharge electrode formed on a dielectric film and closing said window, said bipolar ion generator element being mounted on said insulating tube in such a manner that said discharge electrode is exposed in said aerosol flow path; and an outer tube accommodating said insulating tube, said opening and said bipolar ion generator element in an airtight manner relative to said aerosol flowing container.
