    • A liquid dispensing device using a piezoelectric member in connection with an atomizing head and a passive metering method to supply liquid to the atomizing head. Preferably, the device is used to but not limited to dispensing of fragrances, insecticides or other aromatic solutions. The piezoelectric member does not vibrate the nozzle plate through which the liquid is dispensed. The passive metering method relies only on surface tension forces within the supply passageway. The device can work with a wider range of liquid properties than existing piezoelectric devices of this type. The passive metering method is robust and consistent, enabling larger and more varied liquid reservoirs because the reservoir height is not a factor in determining the performance of the device. The atomizing head functions with a wider range of liquids than atomizers whose nozzle plates are directly excited.
    • 使用与雾化头相关的压电元件的液体分配装置和向雾化头供应液体的被动计量方法。 优选地,该装置用于但不限于分配香料,杀虫剂或其它芳香族溶液。 压电元件不会使分配液体的喷嘴板振动。 被动计量方法仅依赖于供应通道内的表面张力。 该装置可以与现有的这种类型的压电装置一起工作,具有更广泛的液体特性。 被动计量方法是坚固和一致的,使得能够更大和更多变化的液体储存器,因为储层高度不是确定装置性能的因素。 雾化头与喷嘴板直接激发的雾化器相比具有更广泛的液体。
