The current common atomization methods include: pressure atomization, air atomization, impingement atomization, and sonic atomization. Wherein, the overall structure of pressure atomization is simple, and the liquid drop is evenly distributed after the atomization, but the required pressure is generally larger. The air atomization makes the particle size of the atomized liquid smaller, but simultaneously, the characteristic of larger air consumption is accompanied, thus relatively increasing heavier economic burden for users. The particles produced by impact atomization are larger and the liquid particles are less uniform, but the spray distribution is wider. The acoustic atomization cost is relatively high and the structure is relatively complex. It follows that nozzles of various atomisation types have different degrees of advantages and disadvantages.
