  • Patent number: 6296196
    Abstract: There is described a battery driven atomizer in which an alternating voltage is applied to a piezoelectric actuation element to cause it to expand and contract and vibrate an atomizing orifice plate. The alternating voltage is controlled to produce a high amplitude vibration during a first portion of a drive period, to initiate atomization, and thereafter to produce a lower amplitude vibration to sustain atomization during the remainder of the drive period. The frequency of the alternating voltage is swept repeatedly during each drive period.
