Fragrance dispenser for evaporating aromatic liquid
First Claim
1. A fragrance dispenser for circulating air and evaporating an aromatic liquid into the air comprisinga wick holder body having a fluid reservoir for holding an aromatic fluid and the like, and a wick receiving passage, said passage communicating with said fluid reservoir and having an exposed wick receiving channel portion, and wherein said wick holder body includes an air passageway extending therethrough and having an air inlet opening and circular air outlet opening, said exposed portion of said wick receiving channel extending adjacent the peripheral edge of said circular outlet opening,a wick longitudinally positioned in said wick receiving passage and being exposed along the wick length received in the channel, said wick having a fluid receiving end disposed in said reservoir for drawing fluid therefrom into said wick,a fan housing mounted to said wick holder body, and a fan mounted to said fan housing for blowing air through said housing and over said exposed wick portion,a wick cover supported by said wick holder body and movable between a substantially closed position covering the exposed portion of the wick and an extended open position where the wick is fully exposed to a flow of air produced by the fan, andmeans operatively connected to said wick cover for moving the wick cover from the substantially closed position into preselected open positions between said closed and extended, open positions 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.

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.
