Pulsed aerosol generation

摘要

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.

主权项

1. A pulsed aerosol generator comprising:
a capillary passage having an inlet and an outlet; a liquid supply operable to supply liquid material to the inlet of the capillary passage only via capillary action along a supply path of capillary action, said supply path essentially free of heating; a power supply adapted to apply voltage across a heater arranged along a heated portion of the capillary passage to heat liquid material in the capillary passage to a temperature sufficient to at least partially volatilize liquid material in the capillary passage such that the liquid material is driven out of the outlet of the capillary passage and forms aerosolized liquid material; and wherein the capillary passage comprises an interior of a tube and the capillary passage includes a constriction at a location adjacent the inlet of the capillary tube.
