Abstract
A fragrance dispenser includes a housing and a plurality of heating elements disposed in the housing. A controller is disposed in the housing to control an amount and temporal distribution of power distributed to each heating element. Prongs extend from the housing to provide power to the controller. A volatile material holder is held within the housing and includes a plurality of reservoirs adapted to align with the corresponding plurality of heating elements, wherein each of the plurality of reservoirs includes a volatile material. A mode selector switch is disposed on the housing. A setting of the mode selector switch at least partly determines the amount and temporal distribution of power distributed by the controller to each heating element. The setting includes at least one of a sequential setting, a concurrent setting, and a combined sequential and concurrent setting.
