Abstract
A volatile material diffuser includes a housing and first and second containers holding first and second volatile materials and having first and second wicks, respectively, in contact with respective volatile materials and extending out of respective containers, wherein the containers are inserted into and detachably attached to the housing. The diffuser further includes first and second heaters disposed within the housing adjacent the first and second wicks, respectively, to vaporize the first and second volatile materials, respectively. A means for providing an air flow is disposed in the housing such that air from the means for providing an air flow transports vaporized volatile materials away from the housing. The heaters are energized in an alternating sequence such that, when a heater is deactivated, the means for providing an air flow cools a wick associated with the deactivated heater.
