Abstract: An apparatus for an electronic aerosol provision system may include a replaceable cartridge for the electronic aerosol provision system or a fixed component of a re-fillable or disposable electronic aerosol provision system. The apparatus includes a reservoir for a source liquid and a carrier module supported within the reservoir. The carrier module defines an airflow path within the reservoir and includes a heating element supported in the airflow path for generating an aerosol from the source liquid and first and second mounting parts which cooperatively engage to support the heating element. The first and second mounting parts cooperatively engage at an interface which extends in a direction substantially parallel to a direction along which air flows in the airflow path when the apparatus is in normal use. A gap between the first and second mounting parts may provide a capillary channel for drawing source liquid to the heating element from the reservoir heating during use.

Abstract: A vapor provision apparatus including a vapor generation chamber containing a vaporizer for generating vapor from a vapor precursor material; and an air channel wall defining an air channel between the vapor generation chamber and a vapor outlet at a mouthpiece end of the vapor provision apparatus through which a user can inhale vapor during use; wherein an inner surface of the air channel wall is provided with at least one protrusion extending into the air channel to modify (redirect) a flow of air in the air channel during use. For example, the at least one protrusion may be arranged to define one or more portions of a helical wall extending into the air channel so as to impart a degree of rotation about an axis of extent of the air channel to air flowing in the air channel during use.
