Description

This disclosure relates to an aerosol generating system and a cartridge for an aerosol generating system. In particular, this disclosure relates to an aerosol generating system having an induction heating assembly and a cartridge for an aerosol generating system having an induction heating assembly, wherein the cartridge includes an aerosol-forming substrate and a susceptor assembly for heating the aerosol-forming substrate. Aerosol generating systems that use induction heating to heat an aerosol-forming substrate to generate an aerosol for user inhalation are generally known in the prior art. These systems typically comprise an aerosol generator including an induction heating assembly and a cartridge containing an aerosol-forming substrate that, when heated, releases volatile compounds and, when cooled, can form an inhalable aerosol. The cartridge may be configured to be connected to the aerosol generator. The induction heating assembly includes at least one inductor coil configured to generate an alternating magnetic field within a cavity. A susceptor, forming part of either the cartridge or the device, is positioned in close proximity to the aerosol-forming substrate and within the alternating magnetic field. When the susceptor is penetrated by the alternating magnetic field, it is heated by at least one of Joule heating from eddy currents induced within the susceptor and hysteresis losses. The heated susceptor heats the aerosol-forming substrate, releasing volatile compounds from it, which, when cooled, form an inhalable aerosol. One advantage of induction heating systems is that the system's electrical components can be isolated from the aerosol-forming substrate and the generated aerosol. Another advantage is that the cartridge structure can be simplified because it does not require an electrical connection to the device. Several susceptor configurations have been described in the prior art. In many of these configurations, a portion of the susceptor is in contact with other parts of the cartridge, such as the cartridge housing. This contact between the susceptor and other parts of the cartridge requires that the other parts of the cartridge in contact with the susceptor be configured to withstand the temperatures reached when the susceptor is heated. Furthermore, this contact can conduct heat from the susceptor, reducing the efficiency of the system that heats the aerosol-forming substrate.
