滴液发生器

Droplet generator
Abstract:
The present invention provides a droplet generator (10) of the velocity modulation type, the generator (10) being configured so that substantially all the modulation energy generated by piezo-electric crystals (60) is transformed into vibration of the nozzle (34). The generator preferably also includes an internal closure mechanism (70) which blocks off the nozzle (34) when the generator is not in operation, but which is de-coupled from the modulation process when the generator is operating.
Abstract(Chinese):

本发明提供了一种速度调制型的液滴发生器（10），发生器（10）被配置为使得压电晶体（60）产生的基本上所有调制能量都转变成喷嘴（34）的振动。 发电机优选地还包括内部闭合机构（70），当发电机不工作时，内部闭合机构（70）阻挡喷嘴（34），但是当发电机工作时，其从调制过程中去耦合。
