ABSTRACT:
A fragrance dispenser for circulating air and evaporating an aromatic fluid into the air is disclosed. The fragrance dispenser include a wick holder body having a fluid reservoir and a wick receiving passage. The passage communicates with the fluid reservoir and includes an exposed wick receiving passage and channel portion. A wick is disposed in the wick receiving channel and has a fluid receiving end disposed in the reservoir for drawing liquid therefrom into the wick and an exposed portion positioned in the exposed portion of the wick receiving channel. A fan housing is connected to the wick holder body and includes a fan for blowing air over the exposed portion of the wick. A wick cover, supported by the wick holder body, is movable between a substantially closed position covering the exposed portion of the wick and an open position where the wick is exposed to the flow of air provided by the fan. A sleeve and linkage mechanism connects the wick cover for moving the wick cover from a substantially closed position and a preselected open position for selectively limiting the amount of air which flows over the exposed portion of the wick and controlling the amount of fluid evaporated from the wick.
