Abstract
An aerosol generator periodically forms aerosolized fragrance material by repeatedly supplying a liquid fragrance material to a capillary passage via only capillary action and heating the capillary passage, such that the liquid fragrance material at least partially volatilizes and is driven out of an outlet of the capillary passage. A wick feeds the liquid fragrance material to an inlet of the capillary passage by capillary action. An apparatus and method for generating such an aerosolized fragrance material, as well as the methods of heating, are disclosed.
