Aerosol provision systems

An apparatus for an electronic aerosol provision system comprising:

• a reservoir for a source liquid;
• and
• a carrier module that defines an airflow path within the reservoir and comprises a heating element supported in the airflow path within the reservoir for generating an aerosol from the source liquid, wherein the carrier module comprises a first part and a second part which cooperatively engage to support the heating element, wherein the first part and the second part of the carrier module cooperatively engage at an interface which extends in a direction that is substantially parallel to a direction along which air flows in the airflow path when the apparatus is in normal use, and wherein the heating element comprises a sheet material extending in a plane which is substantially parallel to the interface between the first part and the second part, and wherein a gap between the first part and second part provides a capillary channel arranged to draw source liquid to the heating element from the reservoir,
• wherein at least one of the first part and the second part of the carrier module comprises one or more locating pegs received in corresponding locating holes of the other of the first part and the second part of the carrier module so as to help maintain their relative alignment, and
• wherein the one or more locating pegs pass through one or more corresponding openings in the heating element so as to help maintain the heating element in position relative to the first and second parts of the carrier module.

• wherein the arrangement of the airflow path within the reservoir is such that the reservoir is around the airflow path, the apparatus further comprising an outer housing in which the carrier module is received such that the reservoir around the airflow path is defined at least in part by a space between the carrier module and the outer housing,
• wherein the apparatus further comprises a first sealing element for providing a seal between the carrier module and the outer housing at one end of the carrier module and a second sealing element for providing a seal between the carrier module and the outer housing at another end of the carrier module, and
• wherein the second sealing element comprises a support tube providing an extension to the air flow path and having a first end coupled to the carrier module and a second end coupled to an aerosol outlet end of the outer housing.
