The invention discloses a basic component unit of a plate-type ozone generator. The basic component unit comprises two end plates and a composite electrode plate arranged between the two end plates, wherein the composite electrode plate comprises an outer frame; a spacing washer and two ceramic dielectric plates respectively arranged on the front and back surfaces of the spacing washer are arranged in the outer frame; a conducting material layer and an insulating dielectric layer are sequentially arranged between the internal surface of each ceramic dielectric plate and the spacing washer from outside to inside; and the external surface of each ceramic dielectric plate is provided with a plurality of insulating washers which protrude outwards. When at least two composite electrode plates are arranged between the two end plates, the base component unit also comprises a cooling plate which is laminated between the two adjacent composite electrode plates. Besides, the invention also discloses an intelligentized ozone generator module containing the basic component unit, and a large-size intelligentized ozone generator set composed of at least one intelligentized ozone generator module.
