ELECTRONIC SMOKING ARTICLE Russian patent published in 2018 - IPC A24F47/00 

FIELD: tobacco industry.

SUBSTANCE: invention relates to innovative smoking articles, such as electronic cigarettes, cigars and aerosol generators. Electronic smoking article 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; capillary having an inlet and an outlet, the inlet in communication with the outlet of the liquid supply reservoir; first and second electrical leads each of which is connected to the capillary operable to heat to a temperature sufficient to at least initially volatilize the liquid material contained within the capillary; 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; a mixing chamber configured to receive air from the air outlet ant at least portion of the initially volatilized liquid material from the capillary for mixing with the air, the capillary is located within the mixing chamber; valve between the outlet of the liquid supply reservoir and an inlet of a capillary, wherein the valve upon closure inhibits a flow of liquid material back into the liquid supply reservoir.

EFFECT: technical result of the invention is improved smoking articles, in particular application of a gas cell based micro pump as a fluid delivery device in an aerosol based smoke delivery device.
