Smoking substitute apparatus

A smoking substitute apparatus comprising:

• at least one main air inlet;
• an aerosol generator for generating an aerosol from an aerosol precursor for inhalation by a user;
• an outlet formed at a mouthpiece;
• an aerosol delivery conduit extending downstream from the aerosol generator to the outlet, the aerosol delivery conduit comprising a side wall;
• at least one air flow path between the main air inlet and the outlet and along the aerosol delivery conduit for conveying the aerosol to the user, the side wall of the aerosol delivery conduit surrounding the air flow path;
• wherein, in operation, the aerosol generator heats the aerosol precursor to form vaporised aerosol precursor, the vaporised aerosol precursor being transported in the air flow and condensing to form aerosol droplets for flow along the aerosol delivery conduit to the outlet,
• wherein the air flow path and the aerosol generator are configured to control the air flow characteristics at the aerosol generator to provide an aerosol with predetermined particle size characteristics at a first position along the air flow path in the aerosol delivery conduit,
• the apparatus further comprising at least one auxiliary air inlet into the aerosol delivery conduit at or downstream of the first position, the auxiliary air inlet being formed through the side wall of the aerosol delivery conduit,
• characterized in that the smoking substitute apparatus further comprises a housing surrounding the aerosol delivery conduit and defining a reservoir for holding the aerosol precursor;
• and wherein the apparatus further comprises a support member connected to the aerosol delivery conduit and the housing and that extends across the reservoir from the side wall of the aerosol delivery conduit to the housing.
