The heater assembly (300) comprises a retention material (302) containing an aerosol-forming substrate in condensed form. The aerosol-forming substrate comprises a first compound and a second compound, the second compound having a higher boiling point than the first compound. At least one airflow path (306) is defined through the retention material (302). The heater assembly (300) comprises at least one heating element (304) shaped to define an interior volume, the interior volume being filled with the retention material. The interior volume has a cross-sectional area that decreases along a longitudinal axis; and the at least one airflow path (306) passes through a first central region (312) of the interior volume and a second central region (310) of the interior volume, the first and second central regions (312, 310) being spaced-apart along the longitudinal axis.

Abstract: An aerosol-generating device (10) for generating an aerosol from an aerosol-forming substrate comprises a cavity (200) having an opening (220) for receiving the aerosol-forming substrate, and at least one induction coil (250,260) located external to the cavity and arranged to generate, in operation, a fluctuating magnetic field within the cavity. The cavity is defined by side walls (210) extending away from the opening. The side walls (210) of the cavity are formed from a nonmagnetic material, preferably a non-susceptor material, and are permeable to air thereby allowing a radial influx of air into the cavity through the side walls.

The cartridge further comprises a septum (160) forming a common wall member of the vaporization chamber and the reservoir chamber as well as a liquid-conveying susceptor arrangement (140) configured and arranged to convey aerosol-forming liquid from the reservoir chamber into the vaporization chamber and to be inductively heated in use with the device in order to vaporize aerosol-forming liquid within the vaporization chamber. In addition, the cartridge comprises a vapor-conveying conduit (120) providing a fluid communication for vaporized aerosol-forming liquid from the vaporization chamber to a region proximal the reservoir chamber. The septum comprises a through hole which the vapor-conveying conduit passes through or is supported in at a distal end portion and at least one filling hole (169) for filling aerosol-forming liquid into the reservoir chamber via the vaporization chamber. The invention further relates to an aerosol-generating article comprising such a cartridge as well as to an aerosol-generating system comprising such an article.

Abstract: The present invention relates to a cartridge of a stick-shaped aerosol-generating article for use with an inductively heating aerosol-generating device. The cartridge comprises a vaporization chamber at a distal end portion of the cartridge for vaporizing aerosol-forming liquid therein, wherein the vaporization chamber comprises at least one air inlet. The cartridge further comprises a reservoir chamber proximal the vaporization chamber for storing aerosol-forming liquid. Furthermore, the cartridge comprises a liquid-conveying susceptor arrangement which is configured and arranged to convey aerosol-forming liquid from the reservoir chamber into the vaporization chamber and to be inductively heated in use with the device in order to vaporize aerosol-forming liquid within the vaporization chamber. Furthermore, the cartridge comprises a vapor-conveying conduit providing a fluid communication for vaporized aerosol-forming liquid from the vaporization chamber to a region proximal the reservoir chamber. Apart from the at least one air inlet and the fluid communication from the vaporization chamber to the region proximal the reservoir chamber, the vaporization chamber is fully enclosed by wall members, wherein any wall member of the vaporization chamber is inductively non-heatable. The invention further relates to an aerosol-generating article comprising such a cartridge as well as to an aerosol-generating system comprising such an article.

Abstract: An aerosol provision device heating system is described. The system includes a heating region that can receive at least a portion of an article comprising aerosol generating material. The system also includes a first susceptor that extends within the heating region, and a second susceptor that at least partially surrounds at least a portion of the heating region. A first induction coil generates a first varying magnetic field that penetrates, and causes heating in, the first susceptor. A second induction coil generates a second varying magnetic field that penetrates, and causes heating in, the second susceptor. The first and second induction coils may be independently controllable.
