Patent ID: 7700052

Claim:
An ozone generator for generating ozone using high voltage discharging between an electrode plate ( 20 ) forming a first electrode and a heat sink ( 30 ) forming a second electrode, the ozone generator comprising: an inner tube ( 22 ) and a middle tube ( 24 ) each of which is made of ceramic and concentrically disposed, the electrode plate ( 20 ) being interposed between the inner tube ( 22 ) and the middle tube ( 24 ), wherein the inner tube is shorter than the middle tube, wherein the electrode plate ( 20 ) is interposed and sealed between the inner tube ( 22 ) and the middle tube ( 24 ) so as not to be subject to oxidation in air during discharging; an adhesive ( 26 ) sealing both ends of the electrode plate between the inner tube ( 22 ) and the middle tube ( 24 ); an electrode pipe ( 40 ) made of metal for electrically connecting to a power source and disposed within the electrode plate ( 20 ), the electrode pipe including an opening at one end thereof for admitting cooling air for cooling heat generated during high-voltage discharging and a return hole ( 42 ) at a side surface portion at another end of the electrode pipe ( 40 ) at another end for reversing a flow of the cooling air, wherein the electrode pipe ( 40 ) comprises an electrode plate fixing screw ( 60 ) screwed at the another end of the electrode pipe ( 40 ) to electrically connect to an electrode terminal ( 20 a ) of the electrode plate ( 20 ) for providing electricity to the electrode plate ( 20 ); a passage formed through a middle of the heat sink ( 30 ); and an outer tube ( 32 ) made of ceramic installed in an inner periphery surface of the passage, the outer tube ( 32 ) being concentrically disposed to maintain a predetermined distance from an outer periphery surface of the middle tube ( 24 ), wherein the heat sink ( 30 ) comprises a plurality of integrally-formed heat-dissipating fins extending radially from an outer surface of the heat sink ( 30 ).
