Abstract

Abstract An ozonizer comprising a pair of electrodes including a grounding electrode and a high voltage electrode, a dielectric substrate disposed between the grounding electrode and the high voltage electrode, a perforated metal substrate disposed in a gap space between the grounding electrode and the dielectric substrate, wherein the perforated metal substrate comprises first spacing means interspaced between the perforated metal substrate and the dielectric substrate for maintaining a constant separation gap therebetween, second spacing means disposed between the perforated metal substrate and the grounding electrode to maintain the perforated metal substrate in position between the dielectric substrate and the grounding electrode, wherein a uniform separation distance promoting a uniform silent discharge is maintained between the perforated metal substrate and the dielectric substrate by the first and second spacing means.
