Abstract: The device includes a substantially L-shaped body including a docking station for mounting a wick-based fragrance dispensing bottle within a range of sizes. The docking station can include a number of resilient support tabs that grasp the neck of the bottle and serve to localize the bottle's top wick to a central plane regardless of bottle size so that it can be adjustably engaged by a movable heater. Resilient guide tabs straddling the plane are stiffer than a resilient latching tab that moves within the plane. The heater can be mounted on a sliding carriage that can move along the plane to closely nest the wick for increased vapor emission and move away to decrease vapor emission.
