Abstract
A liquid atomizing device for dispensing liquid droplets includes a container for holding a liquid, the container having a porous wick positioned to communicate the liquid from the container, and an orifice plate with apertures, the orifice plate being vibrated by a piezoelectric element to cause liquid communicated from the container to be atomized and dispensed as liquid droplets through the apertures. The device employs a unique placement and design of heaters or fans to promote evaporation and dispersion of the atomized liquid while the liquid is airborne.
