Title:
PLUG-IN TYPE LIQUID ATOMIZER
Document Type and Number:
WIPO Patent Application WO2003047766
Kind Code:
A3
Abstract:
A piezoelectrically actuated liquid atomizer device which applies alternating voltages from an ordinary wall outlet to a piezoelectric actuator intermittently and at a high rate sufficient to cause an atomization plate which is vibrated by the actuator to form small droplets from liquid which is supplied to the plate. The intermittent application of voltages to the piezoelectric actuator is carried out according to a duty cycle in which the off times are adjustable. An override of the duty cycle is provided so that the piezoelectric actuator operates continuously for intervals which are manually or automatically controlled.
