ELECTRONIC CIGARETTE Russian patent published in 2017 - IPC A24F47/00 

FIELD: tobacco industry.

SUBSTANCE: invention relates to electronic cigarette. Electronic cigarette comprises heater for evaporation of liquid substance in order to generate vapour, mouthpiece insert with at least two deflecting protrusions, located at the ends of inclined channels; air flow deflector, at least partially located near heater and prevents incoming air to reduce vapour output due to cooling of heater during drawing cycles; outer cylindrical tube, extending in longitudinal direction; inner cylindrical tube, located in outer cylindrical tube; means of feeding liquid, containing a liquid substance and located in outer annular space between outer and inner cylindrical tubes; central air channel, connected to inlet end of inner cylindrical tube; a wick connected with liquid supply means and with a heater, so as to feed liquid substance to heater to heat the liquid substance heater to temperature sufficient for its evaporation and formation of vapour in inner cylindrical tube; electric power supply to apply voltage on heater; and at least one air inlet opening, designed to supply air into central channel when electronic cigarette is drawn, wherein heater is located in inner cylindrical tube at its outlet with a gap relative to central air channel; and air flow deflector is configured for removal of at least some part of air flow from surface of heater and comprises an impermeable plug, arranged on outlet end of central air channel, and at least one radial air channel, extending from inlet end of central air channel to external longitudinal air channel, which at least partially surrounds output end of central air channel, when air flow deflector is configured to direct airflow from surface of heater.

EFFECT: technical result is ensuring high yield of aerosol and better taste in mouth.
