SMOKING ARTICLE Russian patent published in 2017 - IPC A24F47/00 

FIELD: tobacco industry.

SUBSTANCE: invention relates to a smoking article, which consists of a smoking part and a mouthpiece connected thereto, wherein smoking part comprises central core made from material which forms when heated an aerosol which is inhaled by smoker, heat-conducting shell surrounding central core, and a fuel layer outside heat-conducting shell, wherein parameters of heat release during combustion of fuel layer and heat transfer parameters of heat-conducting shell are chosen from condition, that during combustion of fuel layer central core is heated through heat-conducting shell to temperature sufficient for evaporation of material of central core and formation of aerosol inhaled by smoker, but lower than temperature of its ignition, mouthpiece has a central channel, adjacent to end of central rod of smoking part to allow passage of aerosol inhaled by smoker, and an annular cavity with an open end, adjacent to end of fuel layer of smoking part, and closed end face on opposite side, in central channel of mouthpiece there is an air rotor with blades, enabling rotation of air rotor around longitudinal axis of article due to air stream inhaled by smoker when drawing, in annular cavity of mouthpiece there is an impeller, connected to air rotor with possibility of transferring axial rotation from air rotor to impeller, and annular cavity is connected with outer space by means of at least one hole.

EFFECT: technical result is preventing penetration of combustion products of fuel layer into respiratory tracts of smoker.
