Aerosol delivery system and method of operating the same

Abstract

An aerosol delivery system comprising an induction heating device (1; 3) and an aerosol-forming article (2; 4) comprising a plurality of aerosol-forming segments (200, 201; 400 , 401); and - at least two different receptors (203, 204; 403, 404). Said induction heating device (1; 3) comprises - a device housing (10; 30) comprising a chamber (11; 31) for containing said aerosol-forming article (2; 4) comprising said plurality of aerosol forming at least a part (20; 40) of a segment (200, 201; 400, 401); - a coil (L) arranged to surround said cavity (11; 31); - a power supply (12); and - power supply electronics (14) connected to said power source (12) and said coil (L). The power supply electronics (14) are configured to supply the coil with an alternating current (I; I 1 , I 2 ) to generate an alternating magnetic field having a predetermined magnetic field strength (H) and frequency (f), the alternating magnetic field is used to generate an aerosol greater than this in the at least one aerosol forming section (200, 201; 400, 401) The heat loss rate (Q LOSS ) thermal power (P S ;P S1 ,P S2 ).

Description

technical field [0001] The present invention relates to an aerosol delivery system comprising an induction heating device and an aerosol-forming article, and a method of operating the aerosol delivery system. Background technique [0002] More conventional smoking articles known previously, such as cigarettes, deliver flavor and aroma to the user due to the combustion process. A large amount of combustible material, mainly tobacco, is ignited and adjacent parts of the material pyrolyze due to the applied heat drawn through it, with typical combustion temperatures exceeding 800°C during smoking. During this heating process, combustible materials undergo inefficient oxidation and produce various distillation and pyrolysis products. When these products are drawn through the body of the smoking article towards the user's mouth, the products cool and condense to form an aerosol or vapor, providing the consumer with the flavors and aromas associated with smoking.

Problems solved by technology

[0008] Since the coils are individual individual coils, the property (e.g. induction) of the individual individual coils affecting the heating of the susceptor may vary to such an extent that individual segments of the tobacco-laden substrate rod may not be heated uniformly, This in turn can cause non-uniform aerosolization of the tobacco flavor compounds, possibly with additional flavor compounds of the tobacco-laden substrate, and thus can cause a non-uniform consumption experience
