An Aerosol-Generating System Comprising A Cartridge With An Internal Air Flow Passage

Patent No. EP3145344 (titled "An Aerosol-Generating System Comprising A Cartridge With An Internal Air Flow Passage") was filed by Philip Morris on May 14, 2015. The application was issued on Jun 15, 2022.

Patent Summary

An electrically heated aerosol-generating system comprises a device housing and a replaceable cartridge. The device housing defines a cavity for receiving the cartridge and contains a power supply configured to provide a high-frequency oscillating current to an inductor coil. The inductor coil is positioned around or adjacent to the cavity, remaining outside the cartridge during use. The cartridge includes a housing containing a liquid aerosol-forming substrate held in an annular space surrounding an internal air passage. A susceptor element is positioned within the cartridge to heat the substrate. Operationally, the inductor coil generates a magnetic field that induces heat in the susceptor element via Joule heating and/or hysteresis losses, vaporizing the substrate to form an aerosol delivered through the internal passage.
