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.
Claims24
A fragrance disperser comprising:
- first and second sources of fragrance,
- first and second flowpaths, each associated with a respective source of fragrance,
- a fan for providing a flow of air along the first and second flowpaths to release the associated fragrances, and
- a flow controller separate from the fan and movable by an actuator between a first position in which air flows along the first flowpath to allow release of the first fragrance and a second position in which air flows along the second flowpath to allow release of the second fragrance,
- wherein the fan is within a housing and the housing includes a chamber housing the fan and first and second passages leading from the housing and forming respectively the first and second flowpaths.
A fragrance disperser comprising:
- first and second sources of fragrance,
- first and second flowpaths, each associated with a respective source of fragrance,
- a fan for providing a flow of air along the first and second flowpaths to release the associated fragrances, and
- a flow controller separate from the fan and movable by an actuator between a first position in which air flows along the first flowpath to allow release of the first fragrance and a second position in which air flows along the second flowpath to allow release of the second fragrance,
- wherein the fan is rotatable in respective opposite first and second senses, rotation of the fan in the first sense passing air through the first flowpath with the flow controller in the first position and rotation of the fan in the second sense with the flow controller in the second position passing air through the second flowpath.
A fragrance dispenser comprising:
- first and second sources of fragrance,
- first and second flowpaths, each associated with a respective source of fragrance,
- a fan for providing a flow of air along the first and second flowpaths to release the associated fragrances, and
- a flow controller separate from the fan and movable by an actuator between a first position in which air flows along the first flowpath to allow release of the first fragrance and a second position in which air flows along the second flowpath to allow release of the second fragrance,
- wherein the flow controller is movable by the actuator to at least one position between said first and second positions to provide a proportionate increase of both fragrances.
