The granted patent (Publication Number: US11883587B2) discloses an aerosol delivery device comprising a control body with a resonant transmitter and a control component to drive it. The device is designed to receive substrate tablets containing a granular substrate material and a susceptor component that can be heated by the resonant transmitter. These tablets have a unique design with passages along the peripheral surface and different end surfaces.
The patent further details the formation of the substrate tablets through processes like wet granulation, dry granulation, or direct compression. The tablets can have various shapes, with a preference for a round profile shape. The susceptor component, which can be a susceptor ring or granular material mixed with the substrate, plays a crucial role in heating the tablet. Additionally, the control body is capable of accommodating multiple substrate tablets with different compositions, susceptor components, and shapes, allowing for customizable aerosol delivery based on user preferences and requirements.
