A heater for an aerosol-generating device is provided, the heater including: a flexible electrically insulating substrate including a first portion, a second portion, and a fourth portion, in which the flexible electrically insulating substrate is rolled into a tube; control electronics disposed on the first portion of the flexible electrically insulating substrate; a heating element including an induction coil and being disposed on the second portion of the flexible electrically insulating substrate; and a susceptor element arranged on the fourth portion of the flexible electrically insulating substrate. An aerosol-generating device is also provided, including a cavity to receive an aerosol-generating article including an aerosol-forming substrate, and the heater. A system is also provided, including the aerosol-generating device and the aerosol-generating article including the aerosol-forming substrate.

An aerosol-generating article is provided for producing an inhalable aerosol upon heating, the article including: a rod of aerosol-generating substrate; a downstream section at a location downstream of the rod and including an aerosol-cooling element in longitudinal alignment with the rod, in which the aerosol-cooling element includes a hollow tubular segment that defines a cavity extending all the way from an upstream end to a downstream end of the hollow tubular segment; and a ventilation zone at a location along the hollow tubular segment, the hollow tubular segment having a length of less than about 10 millimetres, in which a volume ratio between a ventilation airflow admitted into the article via the ventilation zone at the location along the hollow tubular segment and a sum of an airflow from the rod and the ventilation airflow is of from about 25 percent to about 45 percent.

Disclosed are a susceptor for an aerosol generation apparatus, and the aerosol generation apparatus. The susceptor includes: a metal body, which may be penetrated by a varying magnetic field to generate heat; and a protective layer, formed on the metal body, the protective layer containing a quasicrystal alloy material to reduce adhesion or deposition of organic matter from a smokable material on the surface of the susceptor. When in use, water vapor, aerosol condensation oil, and the like from the smokable material cannot spread on the surface of the quasicrystal alloy material, and can be maintained in a substantially spherical shape and can be easily separated from the susceptor. Meanwhile, solid-phase organic matter such as tobacco slag and carbon deposition falling on the susceptor is difficult to be stubbornly bound to the protective layer, without forming stubborn adhesion or deposition.

In some implementations, the susceptor pouch comprises the consumable unit. In other implementations, the substrate material is contained within a substrate container.

A heater assembly for accommodating and heating an aerosol generating article includes an accommodation space into which the aerosol generating article is inserted, a coil surrounding at least part of the accommodation space and configured to generate an induced magnetic field, and a susceptor disposed in the accommodation space and configured to generate heat according to the induced magnetic field, wherein, in a state in which the aerosol generating article is fully inserted into the accommodation space, a distal end portion of the susceptor is placed upstream of a boundary between the tobacco rod and the filter rod by a preset distance inside the aerosol generating article.

The present disclosure is directed to an aerosol delivery device and a holder for use with a removable substrate cartridge. The removable cartridge comprises an ignitable heat source and a substrate portion that includes a substrate material having an aerosol precursor composition configured to form an aerosol upon application of heat thereto. The holder includes a main body defining a receiving chamber configured to receive the substrate cartridge, a power source, and an inductive heating assembly. A least a portion of the inductive heating assembly is integral with the main body and is configured to ignite the ignitable heat source and to heat at least a portion of the substrate material.

Methods of embedding an elongate susceptor within a thermoplastic body and systems that perform the methods are disclosed herein. The methods include extending the elongate susceptor such that an extended portion of the elongate susceptor extends between a guide structure and a body-contacting structure. The methods also include heating a segment of the elongate susceptor to produce a heated portion of the elongate susceptor. The methods further include pressing a leading region of the heated portion of the elongate susceptor through a body surface of the thermoplastic body and into the thermoplastic body. The methods also include operatively translating at least one of the guide structure, the body-contacting structure, and an application tool that includes the guide structure and the body-contacting structure along an embedment pathway for the elongate susceptor.

A consumable for an aerosol generating device, methods and systems for manufacturing a consumable, and methods for using a consumable are provided. The consumable includes a columnar portion of aerosol generation substrate; and a heating element embedded in the columnar portion. The heating element includes a base portion and a plurality of elongate portions extending from the base portion along the columnar portion. The heating element is adapted to be driven towards the columnar portion via a force applied to the base portion.
