Patent ID: 11240885

Abstract:
There is provided an electrically operated aerosol-generating device for heating an aerosol-generating article including an aerosol-forming substrate by heating a susceptor element positioned to heat the substrate. The device includes a housing defining a chamber configured to receive at least a portion of the article, an inductor including an inductor coil disposed around at least a portion of the chamber, and a power source connected to the inductor coil and configured to provide a high frequency electric current to the inductor coil to generate a fluctuating electromagnetic field to heat the susceptor element and thereby heat the substrate. The inductor further includes a flux concentrator disposed around the inductor coil and configured to distort the fluctuating electromagnetic field towards the chamber. The flux concentrator includes a plurality of discrete flux concentrator segments positioned adjacent to one another. An aerosol-generating system and an inductor assembly are also provided.
