  • Fragrance dispersers
    Publication number: 20070036688
    Abstract: A fragrance disperser includes a first source (25) of fragrance associated with a first flowpath (21) and a second source of fragrance (26) associated with a second flowpath (23). A fan (17) provides a flow of air along the first flowpath (21) or the second flowpath (23) to release the associated fragrance. A flow controller (38, 52) is movable by an actuator (34) to open and close the flowpaths (21, 23) so that only one fragrance is released at a time or a proportionate mixture of the two fragrances is released.
