Abstract:
An inductive heating assembly is provided for generating an aerosol from an aerosol-forming liquid, the assembly including: a ring-shaped liquid retention element configured to hold and to transport the aerosol-forming liquid; and a ring-shaped susceptor element coaxially arranged at an axial end face of the ring-shaped liquid retention element and being configured to heat the aerosol-forming liquid within the ring-shaped liquid retention element, the ring-shaped susceptor element including an inductively heatable susceptor material exclusively confined within an inner ring portion having an outer radial extension of at most 50 percent of an outer radial extension of the ring-shaped liquid retention element. An aerosol-generating article including the inductive heating assembly is also provided.
