Problems solved by technology

[0008] However, since the coils are individual individual coils, the properties (e.g., inductance) of the individual individual coils affecting the heating of the susceptor may vary to some extent such that individual segments of the tobacco-laden substrate rod may not be heated evenly , which in turn can cause non-uniform aerosolization of tobacco flavor compounds and possibly additional flavor compounds of the tobacco-laden matrix, and thus can cause a non-uniform consumption experience

Embodiment Construction

[0062] figure 1 A first embodiment of an induction heating device 1 according to the invention is shown, wherein an aerosol-forming article 2 is arranged in a cavity 11 of a device housing 10 of the induction heating device 1, the induction heating device 1 and the aerosol-forming article 2 jointly forming a Aerosol delivery systems of the present invention. Such as figure 1 As shown in , the aerosol-forming article 2 may comprise a tobacco-filled solid substrate 20 and a filter portion 21 , however, this is by way of example only and not mandatory. Such asfigure 1 In addition, it can be seen that the tobacco-laden solid matrix 20 includes susceptor particles 22 distributed in the tobacco-laden matrix 20, but in figure 1 is depicted only in the lower half of the tobacco-laden substrate 20. As already mentioned, the aerosol-forming article 2 may be in the shape of a rod, wherein the inner surface 110 of the cavity 11 is sized and shaped to accommodate the tobacco-filled subs...

Abstract

An inductive heating device (1) for heating an aerosol-forming substrate (2) comprising a susceptor (22) comprises: a device housing (10) comprising a cavity (11) having an internal surface (110) shaped to accommodate at least a portion of the aerosol-forming substrate (2), a coil (L) arranged to surround at least a portion of the cavity (11), an electrical power source (12), and a power supply electronics (14) connected to the electrical power source (12) and to the coil (L), for supplying an alternating current to the coil (L), wherein the coil is a single coil (L) having a plurality of connection taps (L11, L21, L31, L12, L22, L32) being arranged at different locations along the coil length to divide the single coil (L) into a plurality of individual coil segments (L1, L2, L3), and wherein the power supply electronics (14) is configured to individually supply the alternating current to each individual coil segment (L1; L2; L3).

Description

technical field [0001] The present invention relates to an induction heating device for heating an aerosol-forming substrate comprising a susceptor, and more particularly to an induction heating device for heating an aerosol-forming article. Background technique [0002] More conventional smoking articles known previously, such as cigarettes, deliver flavor and aroma to the user due to the combustion process. Masses of combustible material, primarily tobacco, are allowed to burn and adjacent portions of the material pyrolyze due to the applied heat drawn through it, with typical combustion temperatures in excess of 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 aroma...
