- providing the electronic article with,a capillary tube,a compressible liquid supply reservoir configured to contain a liquid, an outlet of the liquid supply reservoir being in communication with an inlet of the capillary tube, the liquid supply reservoir being formed from an elastomeric material,a power source,a pressure switch in electrical communication with the power supply,an electrical heater operative upon the capillary tube;
operating a heated capillary tube by,delivering the liquid to the capillary tube by manually communicating pressure to the compressible liquid supply reservoir;
activating the pressure switch to communicate electrical power from the power source to the electric heater, wherein the heated capillary tube discharges the liquid communicated to the capillary tube in an at least partially volatized condition;
the discharging including,discharging the liquid into a chamber on an end of the capillary tube to produce a vapor; and

Abstract
An electronic cigarette includes a capillary tube in communication with a liquid supply including liquid material and a heater operable to heat the capillary tube to a temperature sufficient to vaporize the liquid material contained therein and form an aerosol. The liquid supply is adapted to be squeezed or otherwise compressed so as to allow a smoker to manually pump liquid to the capillary tube and simultaneously activate the heater.
