Aerosol generator including multi-component wick

摘要

An aerosol generator includes a composite conduit to transport multiple liquids to a heating element at flow rates such that the liquids arrive at the heating element in desirable concentrations. The heating element volatilizes the liquids to form volatilized fluid, which mixes with ambient air to form an aerosol with desirable concentrations of the multiple liquids.

主权项

1. An aerosol generator comprising:
a reservoir configured to hold multiple liquids, wherein the multiple liquids are separated into discrete layers with lower density liquids forming over higher density liquids; a heating element operable to volatilize the multiple liquids to form a volatilized fluid, which mixes with ambient air to form an aerosol; a composite conduit to transport the multiple liquids to the heating element, wherein the composite conduit includes a first capillary tube, which is concentrically surrounded by second and third capillary tubes, and wherein the first, second, and third capillary tubes have different lengths adapted to be in contact with a different liquid within the multiple liquids; and a mouthpiece configured to receive the aerosol, from which the aerosol may be inhaled.
