DUAL CAPILLARY FLUID VAPORIZING DEVICE

摘要

A fluid vaporizing device (10) useful for vaporizing fluid into an aerosol and includes first and second capillary tubes (20,30) connected electrically in series by providing separate electrodes (50, 52) at the inlet ends (20a, 30a) of each capillary tube (20,30), and connecting the outlet ends (20b, 30b) of the capillary tubes (20,30) by an electrical connection (54) that connects the outlet ends (20b,30b) both electrically and thermally. The capillary tubes (20, 30) are heated by the flow of electricity therethrough, and liquid flowing through the tubes (20,30) is vaporized. The outlet ends (20b, 30b) of the capillary tubes (20, 30) are easily maintained at a temperature for optimizing aerosol generation since there is minimal heat loss through the connection (54) connecting the outlet ends (20, 30b).
