US 2021/0276034 A1 · APERTURE PLATE STRUCTURE AND APPLICATIONS THEREOF

Abstract

The present invention discloses an aperture plate and an aerosol generator. The aperture plate is made by metal materials with a plurality of apertures. The aperture plate has a multi-layer structure, which comprises a substrate, a protective layer and/or at least one intermediate layer between the substrate and the protective layer. The intermediate layer is configured to enhance the adhesion between the substrate and the protective layer, so that it can increase the durability of the aperture plate. The aperture plate can be a dome-shaped, a flat-shaped or an irregular shape. The aperture plate of the present invention can optimize the volume and size of droplets under the vibration at certain frequency.
