摘要： A handheld aerosol generating system comprises a cartridge (4) removably attached to an aerosol generating device (2), the cartridge (4) supplying an aerosol generating liquid (31) to mixing chamber (14) along a fluid flow path (32). The system is primed before use by reducing the pressure in at least part of the mixing chamber (14) below ambient pressure to draw fluid along the fluid flow path (32) and expel any air that entered the fluid flow path (32) when the cartridge (4) was attached. The said part of the mixing chamber (14) may be isolated from a mouthpiece (10) during the priming operation. A liquid jet head (82) may be used to deliver aerosol generating liquid (31) into the mixing chamber (14).

摘要： A cartridge (4) for an aerosol generating device (2) comprises a liquid storage passage (20) having an inlet (22) open to atmosphere and an outlet (24) for supplying aerosol generating liquid (18) to the aerosol generating device (2), the liquid storage passage (20) being configured to retain aerosol generating liquid (18) by capillary action. The liquid storage passage (20) is preferably a long and narrow passage, which may comprise a plurality of fluidly connected passage sections (30) configured in a serpentine arrangement. The cartridge (4) may comprise a plurality of said liquid storage passages (20) arranged in respective tiers (40). The cartridge (4) is suitable for supplying the aerosol generating liquid (18) to liquid jet heads (28) in the device (2).
