Definitions

  • the present invention concerns an aerosol generating device with improved modularity.
  • aerosol generation devices comprise a storage portion for storing an aerosol forming precursor, which can comprise for example a liquid or a solid.
  • a heating system is formed of one or more electrically activated resistive heating elements arranged to heat said precursor to generate the aerosol.
  • the aerosol is released into a flow path extending between an inlet and outlet of the device.

  • the precursor is stored in a removable cartridge.
  • the aerosol generating device comprises then an outside casing defining a cavity in which the cartridge may be inserted.
  • a screw-threaded or magnetic connection or any other connection means can for example be used.
  • the shape of the cavity in which the cartridge may be inserted cannot be modified and therefore only one type of cartridge may be inserted.
