Embodiment Construction
[0182] figure 1 A schematic diagram of an induction heating element 10 according to an embodiment of the disclosure is shown. The induction heating element 10 is an elongated tubular element with a circular cross-section. The induction heating element 10 includes a first susceptor 12 , a second susceptor 14 and a space 15 between the first susceptor 12 and the second susceptor 14 . The first susceptor 12 and the second susceptor 14 are each an elongated tubular element having a circular cross-section. The first susceptor 12 and the second susceptor 14 are coaxially aligned end-to-end along the longitudinal axis A-A.
[0183] The induction heating element 10 includes a cylindrical cavity 20 open at both ends, which is defined by the inner surfaces of the first susceptor 12 and the second susceptor 14 . Cavity 20 is configured to receive a portion of a cylindrical aerosol-generating article (not shown) including an aerosol-forming substrate such that the outer surface of the ...

The present invention relates to a method of controlling an aerosol-generating system, the aerosol-generating system, and an aerosol-generating device for the aerosol-generating system. The aerosol-generating system comprises an inductive heating arrangement configured to heat an aerosol-forming substrate; and a power supply configured to supply power to the inductive heating arrangement. The inductive heating arrangement comprises an inductive heating element (10) including at least one susceptor (12, 14) that is heatable by penetration with a varying magnetic field to heat the aerosol-forming substrate; a first inductor coil (32); and a second inductor coil (34). The method comprises driving a first varying current in the first inductor coil (32) to generate a first varying magnetic field for heating a first portion of the inductive heating element (10), and controlling the first varying current such that the temperature of the first portion of the inductive heating element (10) increases from an initial temperature to a first operating temperature. The method further comprises driving a second varying current in the second inductor coil (34) to generate a second varying magnetic field for heating a second portion of the inductive heating element (10), and controlling the second varying current such that the temperature of the second portion of the inductive heating element (10) increases from an initial temperature to a second operating temperature. The second varying current is not driven when the first varying current is driven, and the first varying current is not driven when the second varying current is driven.
Description
technical field [0001] The present disclosure relates to a method of controlling an aerosol generating system with an induction heating device, an aerosol generating system with an induction heating device and an aerosol generating device with an induction heating device. Background technique [0002] A number of electrokinetic aerosol-generating systems have been proposed in the art in which an aerosol-generating device with an electric heater is used to heat an aerosol-forming substrate, such as a tobacco filter segment. One purpose of such an aerosol generating system is to reduce known types of noxious smoke constituents produced by the combustion and pyrolytic degradation of tobacco in conventional cigarettes. Typically, the aerosol-generating substrate is provided as part of an aerosol-generating article which is inserted into a cavity of the aerosol-generating device. In some known systems, in order to heat the aerosol-forming substrate to a temperature at which the ...
