Abstract: An aerosol forming component for volatilizing a liquid in an aerosol delivery device is disclosed. The aerosol forming component includes a first aerosol-forming member configured to be heated up to a first operating temperature and thereafter to a second higher operating temperature, and a second aerosol-forming member configured to be heated up to at least the first operating temperature as the first aerosol-forming member reaches the second higher operating temperature so that liquid volatilized from the two aerosol-forming members mix with one another.

Abstract: An electronic vapor provision system includes a vaporizer for vaporising liquid for inhalation by a user of the electronic vapor provision system; a power supply comprising a cell or battery for supplying power to the vaporizer; a sensor for measuring the rate of airflow through the electronic vapor provision system as a result of the inhalation by the user; and a control unit for controlling the power supplied to the vaporizer based on a cumulative airflow for this inhalation by the user, wherein the cumulative airflow is determined based on the measurements of airflow rate by the sensor. Such a system allows the user control over the amount of vaporized liquid obtained in a given inhalation based on the cumulative airflow for the given inhalation.

Abstract: A vaporizer assembly including a vaporizer and a matrix suitable for retaining a vaporizable liquid, wherein the vaporizer includes first and second surfaces forming a common edge, the first surface having a greater surface area than the second surface, wherein the vaporizer is in contact with the matrix via the second surface.

Abstract: An aerosol-forming member comprising a sheet of material configured to wick and to heat a solution is disclosed. The sheet of material comprises a non-planar inner major surface having a capillary structure configured to emit vapor during use, and an outer major surface that is configured to emit less vapor than the inner major surface during use.

Abstract: An aerosol provision system, such as an electronic cigarette, comprises an aerosol source for generating an aerosol from a source liquid comprising a liquid formulation, for example containing nicotine, is described. The system comprises an air channel arranged between the aerosol source and a mouthpiece opening through which a user inhales the aerosol during use. The air channel is defined by a wall, and at least a portion of an inner surface of the wall is provided with a surface finish to increase the wettability of the surface to the liquid formulation. Increasing the wettability of the air channel can help reduce the likelihood of the aerosol condensing into droplets of the liquid formulation on the walls of the air channel and being drawn into a user's mouth therefrom.
