Abstract

A volatile material atomizing device comprises a housing having a fan, a fluid outlet, a plurality of air inlets and a plurality of air outlets. The plurality of air outlets are positioned at least partially around the fluid outlet. A fluid reservoir includes a wick and containing a volatile material. The fluid reservoir is disposed within the housing. An atomizing assembly is in fluid communication with the wick and positioned in the housing. The atomizing assembly is configured to dispense the volatile material out of the fluid outlet.
