Abstract: An aerosol-generating device is provided, including: a heater casing housing a heating chamber, the heating chamber configured to receive an aerosol-generating article including an aerosol-forming substrate; an air-flow tube configured to provide air to the heating chamber; and a controller configured to control operation of the aerosol-generating device, in which the heater casing, the air-flow tube, and the control element are mounted to one another and form a self-supporting component of the aerosol-generating device. A self-supporting component for an aerosol-generating device, and an aerosol-generating system including the aerosol-generating device and an aerosol-generating article, is also provided.

Abstract: A heater assembly for an aerosol-generating device is provided, including: an elongate heating chamber configured to heat an aerosol-forming substrate; and a heating element arranged around the elongate heating chamber, the elongate heating chamber having a first length and the heating element having a second length, the first length of the elongate heating chamber being greater than the second length of the heating element, such that there is a proximal distance between a proximal end of the elongate heating chamber and a proximal end of the heating element, and the proximal distance being between 0.1 millimeter and 4 millimeters. An aerosol-generating device including the heater assembly, and an aerosol-generating system including the aerosol-generating device and an aerosol-generating article, are also provided.

Abstract: A heating assembly for an aerosol-generating device is provided, the heating assembly including: a substrate layer that is an electrically isolating substrate layer; and a heating element arranged on a first portion of the substrate layer, the substrate layer including a second portion on which the heating element is not disposed, the substrate layer being rolled into a tubular shape, such that the first portion of the substrate layer is positioned as an inner layer, the second portion of the substrate layer being positioned as an outer layer surrounding the first portion of the substrate layer, and the heating element being arranged between the first portion of the substrate layer and the second portion of the substrate layer.

Abstract: A heater assembly for an aerosol-generating device is provided, including: a heating chamber configured to heat an aerosol-forming substrate; a heater casing arranged around the heating chamber, the heater casing being arranged radially distanced from the heating chamber; a first connecting wall and a second connecting wall; and an air-tight hollow space defined between the heating chamber, the heater casing, and the first and the second connecting walls, the air-tight hollow space being filled with a gaseous composition at ambient pressure, and a heating element being arranged at least partly around the heating chamber. An aerosol-generating device including the heater assembly, and an aerosol-generating system including the aerosol-generating device and the aerosol-forming substrate, are also provided.
