US Patent 11375753 Aerosol-generating device having an inductor coil with reduced separation

An aerosol-generating device is provided, including a housing defining a chamber configured to receive at least a portion of an aerosol-generating article; an inductor coil disposed at least partially within the chamber, the housing defining a recess in an inner surface of the chamber, and the inductor coil being at least partially disposed within the recess; and a power supply and a controller connected to the inductor coil and configured to provide an alternating electric current to the inductor coil such that the inductor coil generates an alternating magnetic field to inductively heat a susceptor element and thereby heat at least a portion of the aerosol-generating article received within the inductor coil.
