Patent ID: 7179432

Claim:
An improved corona generator structure, comprising essentially of: an insulating sleeve possessing an insulating effect; a ground tube body having a connecting plate extending from an end thereof, wherein said ground tube body is sheathed within said insulating sleeve, and said connecting plate thereon penetrates outside said insulating sleeve; a sealing lid having a salient protruded from a top edge thereof, said salient being provided with a port, wherein said sealing lid is coupled within said insulating sleeve and connected to an end portion of said ground tube body such that said connecting plate of said ground tube body penetrates through and outside said port, and an insulating layer is coated onto the top surfaces of said insulating sleeve so as to seal said sealing lid and said ground tube body in said insulating sleeve; at least one piece of high voltage electrode plate uniformly provided with a plurality of apertures and a plurality of venting ports, an inner side of said aperture being engaged with a spacer, a conductive plate being extended from an end of said high voltage electrode plate, wherein said high voltage electrode plate is disposed onto an external surface of said insulating sleeve, and said conductive plate thereon penetrates through and outside said insulating sleeve; and a first and a second retaining sleeves provided with two multiple wind-guiding channels corresponding to each other on side peripheries thereof, two inserting ports on opposite surface thereof, and a retaining port on a proper position of said first retaining sleeve, wherein said first and said second retaining sleeves are coupled with both end of said insulating sleeve such that said salient of said sealing lid penetrates through and outside said retaining port of said first retaining sleeve, and said conductive plate of said high voltage electrode plate penetrates outside said inserting ports of said first retaining sleeve such that both end portions of said high voltage electrode plate are clamped by said first and said second retaining sleeves so as to be firmly positioned on a surface of said insulating sleeve.
