Aerosol delivery system and method of operating the aerosol delivery system

Abstract

An aerosol delivery system comprises an inductive heating device (1; 3) and an aerosol-forming article (2; 4). The aerosol-forming article (1; 3) comprises - a plurality of aerosol-forming segments (200, 201; 400, 401); and - at least two different susceptors (203, 204; 403, 404). The inductive heating device (1; 3) comprises - a device housing (10; 30) comprising a cavity (11; 31) to accommodateat least a portion (20; 40) of the aerosol- forming article (2; 4) comprising the plurality of aerosol- forming segments (200, 201; 400, 401); - a coil (L) arranged to surround the cavity (11; 31); -an electrical power source (12); and - a power supply electronics (14) connected to the electrical power source (12) and to the coil (L). The power supply electronics (14) is configured to supply an alternating current to the coil (I; I1, I2) to generate an alternating magnetic field having magnetic field strength (H) and a frequency (f) to in at least one aerosol-forming 20 segment (200; 201; 400; 401) generate a thermal power (PS;PS1, PS2) which is greater than the rate of heat loss (QLOSS) of this aerosol-forming segment (200; 201; 400; 401).

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
