  • Patent number: 6715487
    Abstract: A fluid vaporizing device useful for vaporizing fluid into an aerosol and includes first and second capillary tubes connected electrically in series by providing separate electrodes at the inlet ends of each capillary tube, and connecting the outlet ends of the capillary tubes by an electrical connection that connects the outlet ends both electrically and thermally. The capillary tubes are heated by the flow of electricity therethrough, and liquid flowing through the tubes is vaporized. The outlet ends of the capillary tubes are easily maintained at a temperature for optimizing aerosol generation since there is minimal heat loss through the connection connecting the outlet ends.
    Type: Grant

    Date of Patent: April 6, 2004

  • Patent number: 6640050
    Abstract: A fluid vaporizing device useful for vaporizing fluid into an aerosol includes a capillary tube made from an electrically conductive material, an upstream electrode connected to the tube, and a downstream electrode connected to the tube and provided with an electrical resistivity sufficient to cause heating of the downstream electrode during operation to approximately the same temperature as the tube at the point of connection. The upstream and downstream electrodes connected to the capillary tube divide the tube into an initial feed section, a heated section, and a tip. A source of material to be volatilized is provided to the tube at the feed section, passes downstream into the heated section, is vaporized, and then exits from the tube through the tip. The temperature profile of the tube along the heated section is controlled by varying parameters to substantially eliminate any effect of the downstream electrode as a heat sink.
