Abstract
A ceiling fan air freshener diffusion device comprising a scent receptive chamber, a removable drawer for holding a volatile scented medium and a heater for volatilizing the scent medium. The chamber comprises a housing defining a cap for mounting to the hub of a ceiling fan and a continuous sidewall extending downward from the cap. The sidewall defines scent diffusion orifices and a drawer receptive opening. A floor is secured to the housing, abutting the sidewall to seal the housing. An adjustment baffle captivated between the floor and the cap also defines scent diffusion control orifices for regulating diffusion of scent in conjunction with the scent diffusion orifices defined in the sidewall. A tab extending from the baffle through an adjustment slot in the side wall is used to control the aperture defined by the sidewall and baffle orifices together. The preferred embodiment uses a switched resistance heating element located within a base below the floor of the chamber to volatilize the scent medium. The base comprises a bottom and upwardly projecting walls. The base defines orifices to receive a lighting kit. Alternatively, byproduct heat from the fan motor or one or more li…
