Abstract
A device comprises a delivery engine comprising a volatile composition and a microporous membrane, and an evaporation assistance element. In some embodiments the device includes a fan is configured to move a volume of air over the microporous membrane to facilitate evaporation of the volatile composition into the atmosphere.
Claims25
1-20. (canceled)
A device comprising:
- a housing;
- a fan assembly positioned within said housing;
- a delivery engine positioned within said housing, wherein said delivery engine comprises:
- a reservoir containing a liquid volatile composition, and
- a microporous membrane in fluid communication with said liquid volatile composition when said delivery engine is activated, wherein said microporous membrane comprises an evaporative surface area of about 2 cm2 to about 100 cm2;
- and
- wherein said fan assembly is configured to move a volume of air at least partially over said microporous membrane to evaporate said liquid volatile composition into the atmosphere.
4 more elements
A method of freshening the air, the method comprising the steps of:
- providing a delivery engine comprising a reservoir for containing a liquid volatile composition;
- using a fan assembly to evaporate the liquid volatile composition from the delivery engine;
- and
- changing one or more of the fan assembly speed, frequency of run time, or on/off time as the liquid volatile composition is evaporated from the delivery engine.
1 more element
A method of freshening the air, the method comprising the steps of:
- providing a housing, the housing comprising a delivery engine and a fan, the delivery engine comprising a reservoir for containing a liquid volatile composition and a microporous membrane in fluid composition with the volatile composition in the delivery engine, wherein the microporous membrane has an evaporative surface area of about 2 cm2 to about 100 cm2;
- and
- moving a volume of air across the microporous membrane with the fan assembly to evaporate the liquid volatile composition from the microporous membrane.
A device comprising:
- a housing;
- a fan assembly positioned within said housing;
- a delivery engine positioned within said housing, wherein said delivery engine comprises:
- a reservoir containing a liquid volatile composition, and
- a microporous membrane in fluid communication with said liquid volatile composition when said delivery engine is activated, wherein said microporous membrane comprises an evaporative surface area of about 2 cm2 to about 100 cm2;
- and
- a controller coupled to the fan assembly, wherein the controller is configured to operate the fan assembly at a fan speed of about 550 rpm to 1750 rpm to move a volume of air at least partially over said microporous membrane to evaporate said liquid volatile composition into the atmosphere.
