Aerosol Generating System With Multiple Inductor Coils

Patent No. EP3664645 (titled "Aerosol Generating System With Multiple Inductor Coils") was filed by Philip Morris on Aug 9, 2018. The application was issued on Jul 22, 2026.

Patent Summary

An aerosol-generating system comprises an aerosol-generating device and an article containing an aerosol-forming substrate and a mouthpiece. The device features a housing with a chamber having an open end for article insertion and a closed end opposite. The chamber defines a heating zone surrounded or flanked by two coils: a first drive coil couplable to an alternating current source and a second resonant coil of a resonant circuit. The second coil is inductively couplable to the first, potentially forming a resonant inductive coupling to increase current flow and magnetic field strength for improved efficiency. The system may further include a power supply, a controller for independent coil operation, and an elongate susceptor element inductively heated by the coils to heat the substrate.
