摘要： An aerosol-generating system is provided, including: a liquid storage portion including a container configured to hold a liquid aerosol-forming substrate and defining an opening at an end thereof; a heater assembly extending across the opening along a plane transverse to a longitudinal axis of the portion and including an arrangement of one or more electrically conductive flat filaments; a capillary material disposed between the portion and the heater assembly and being configured to convey the substrate to the one or more filaments; and conductive contacts, disposed in electrical contact with corresponding contacts of the heater assembly, the portion being disposed at a first side of the heater assembly and a first airflow channel being disposed at a second side of the heater assembly, and the first airflow channel defining an airflow pathway that extends in a direction orthogonal to the plane and to a surface of the capillary material.

摘要： An aerosol-generating system is provided, including a liquid storage portion including a container configured to hold a liquid aerosol-generating substrate and defining an opening; a heater assembly extending across the opening along a plane transverse to the opening and including at least one electrically operated heating element; and a first channel defining a first flow route, a portion of the first channel being arranged with respect to the plane transverse to the opening such that at least a portion of the first channel is configured to direct air originating from outside the system to impinge against and across a surface portion of the at least one electrically operated heating element. A method for guiding an airflow in an electrically operated aerosol-generating system is also provided.

摘要： A smoking article having a proximal end and a distal end is provided, including a combustible heat source disposed at the distal end; an aerosol-forming substrate downstream of the combustible heat source; a mouthpiece downstream of the aerosol-forming substrate and disposed at the proximal end; and a tubular element, which is slideable from a first position towards the distal end to a second position. In the second position, the tubular element at least partially extends over the combustible heat source and is configured to reduce the air supply to the combustible heat source. The tubular element is configured to modify a heat output of the combustible heat source, and to control a resistance-to-draw of the smoking article by selectively covering air inlets.
