Abstract

The invention discloses a mesh microstructure for atomizing high-viscosity liquid and a manufacturing method of the mesh microstructure. The manufacturing method comprises the steps that a mesh template is manufactured, wherein the mesh template comprises a convex column array; a mesh material layer is formed on a substrate; the mesh material layer is imprinted on the mesh template, wherein the convex column array is completely sunken into the mesh material layer, and the mesh material layer is solidified; and the mesh template and the substrate are removed to obtain a vibrating membrane, wherein meshes are formed in the position, exactly facing the convex column array, of the vibrating membrane. The mesh microstructure can achieve normal-temperature atomization of low-viscosity liquid andthe high-viscosity liquid, atomization is sufficient, the atomized liquid drop is small in size and large in flow, the meshes are smooth in surface, firm and easy to clean, and the manufacturing method is stable in technology and easy to repeat.

Description

technical field [0001] The invention belongs to the technical field of liquid atomization, and in particular relates to a mesh microstructure for high-viscosity liquid atomization and a manufacturing method thereof. Background technique [0002] The mesh microstructure used for high-viscosity liquid atomization is a spray device that drives the mesh sheet to vibrate through the vibration of the piezoelectric sheet, contacts the liquid, and drives the liquid to spray. Among them, the mesh diameter of the liquid outlet surface on the vibrating mesh sheet is a key factor determining the diameter of the atomized droplet, and the microstructure of the mesh is one of the factors determining the viscosity of the atomized liquid. At present, the methods of realizing vibrating mesh microstructure in the industry are mainly laser ablation, chemical etching or electroforming technology. The aperture, shape requirements and material selection of the atomizing mesh are greatly restricted...
