  • Publication number: 20250024889
    Abstract: A vapour delivery apparatus is configured to deliver a vapour comprising an active ingredient to a user drawing air through the apparatus for inhalation. The apparatus comprises an air passage defined between an air inlet and an outlet, and a vapour generator arranged in the air passage. The vapour generator comprises a substrate loaded with a source of an active ingredient for generation of the vapour. The vapour generator also comprises a constricted air flow region adapted to provide a higher air flow velocity in the constricted air flow region than an air flow velocity in the air passage upstream of the vapour generator for a given air flow rate from the air inlet to the outlet. The constricted air flow region is bounded on at least one side by the substrate to extract vapour from the substrate into the air flow in the constricted air flow region. There is also provided a method of using a vapour delivery apparatus.

  • Publication number: 20230116576
    Abstract: The present disclosure relates to an aerosol delivery component (e.g., a smoking substitute component) comprising: a first aerosolisation portion (which may be a passive aerosolisation portion) configured to generate a first aerosol from a first aerosol precursor; and a second aerosolisation portion (which may be an active aerosolisation portion) configured to generate a second aerosol from a second aerosol precursor. The component further comprises a mouthpiece nozzle rotatable between a first position and a second position, wherein in the first position the component is configured to supply the first aerosol and the second aerosol through the mouthpiece nozzle, and in the second position the component is configured to supply only the second aerosol through the mouthpiece nozzle.
