AEROSOL-GENERATING SYSTEM WITH IMPROVED AIR FLOW CONTROL

摘要

There is provided an aerosol-generating system (10) comprising an aerosol-generating device (12) and an aerosol-forming cartridge (14) comprising at least one aerosol-forming substrate (32), wherein, in use, the aerosol-forming cartridge (14) is at least partially received within the aerosol-generating device (12). The system (10) further comprises at least one electric heater (34) arranged to heat the at least one aerosol-forming substrate (32) during use, at least one air inlet (18) and at least one air outlet (20). In use, the aerosol-generating system (10) further comprises an air flow channel (40) extending between the at least one air inlet (18) and the at least one air outlet (20). The air flow channel (40) is in fluid communication with the aerosol-forming substrate (32), and the air flow channel (40) has an internal wall surface (42) on which one or more flow disturbing devices (44) are disposed, the flow disturbing devices (44) being arranged to create a turbulent boundary layer in a flow of air drawn through the air flow channel (40).
