Abstract

A battery operated atomizer device comprising, in a housing (22), a liquid reservoir (30) from which a capillary type liquid delivery system (38) extends to contact a piezoelectric actuator an atomization plate assembly (34), the assembly (34) being supported by means of wire-like elements (36) in cantilever fashion over the liquid delivery system, the liquid delivery system comprising an outer tubular member (52) and a solid rod (56) which have facing surfaces configured to define between them, longitudinal capillary liquid passages.
