ELECTRONIC SMOKING ARTICLE

摘要

An electronic smoking article is disclosed, which includes an outer housing extending in a longitudinal direction; a micro pump system configured to pump a liquid material contained within a liquid supply reservoir through an outlet of the supply reservoir into a capillary; the capillary having an inlet and an outlet, the inlet in communication with the outlet of the liquid supply reservoir; a heating arrangement operable to heat the capillary to a temperature sufficient to at least initially volatilize the liquid material contained within the capillary; a power supply operable to apply voltage to the micro pump gas cell to generate a gas to drive the liquid material out of the liquid supply reservoir into the inlet of the capillary; at least one air inlet; and whereby air is mixed with the volatilized material to form an aerosol.
