The invention discloses a creeping discharge basic unit, an ionic wind purifier and an ion quantity control system. The creeping discharge basic unit comprises two electrodes plated with a first non-metallic medium on the surface, and the two electrodes are embedded in a second non-metallic medium, the dielectric constant of the second non-metallic medium is greater than the dielectric constant of the first non-metallic medium, and the difference between the dielectric constant of the second non-metallic medium and the dielectric constant of the first non-metallic medium is greater than or equal to 3, so a discharge space of an electric field is formed on the surface of the second non-metal medium. The creeping discharge basic unit is provided with an air distribution duct, so that air forcibly passes through the discharge surface. The ion quantity control system comprises a discharge controller and a single-chip microcomputer which are connected with the discharge unit, and a gas detection module connected w
