AI Technical Summary
Existing microporous atomizing sheet substrates and micromesh films adopt an integrated structure, and the materials are mostly precious metals, resulting in high production costs.
The micro-mesh diaphragm, which uses a stainless steel support sheet and a palladium-nickel alloy material, has a separate structure. The piezoelectric ceramic sheet is used for atomization. Only the micro-mesh diaphragm uses palladium-nickel alloy material, combined with the stainless steel support sheet, which reduces material costs.
The split structure significantly reduces material costs while maintaining the performance of the atomizing plate, achieving an economical and efficient atomization effect.
