Patent abstract

A micro-spray system resonance frequency modulation method and device designed to minimize resonance frequency drift during atomization involves using a resonance frequency modulation unit for modulating resonance frequency and nodes, controlling and calibrating resonance frequency, and performing real-time measurement and correction to prevent operating frequency from drifting beyond a preferred operating frequency range, with a view to increasing spray flow and spray area, minimizing effects of ambient factors, and overcoming drawbacks of prior art.
