Aerosol-generating device with sensorial media cartridge
The invention relates to an aerosol-generating device ( 10 ) comprising a top portion ( 20 ), a main portion ( 70 ), and a cartridge ( 50 ). The top portion comprises a proximal end comprising a cavity ( 22 ) for receiving an aerosol-generating article ( 12 ). The top portion further comprises a distal end comprising a top cartridge connector ( 24 ) and a top airflow channel extending from the top cartridge connector to the cavity. The main portion comprises a proximal end comprising a main cartridge connector ( 72 ). The main portion furthers comprises a main air inlet and a main airflow channel extending from the main air inlet to the main cartridge connector. The top cartridge connector is removably attachable to a proximal end of the cartridge and the main cartridge connector is removably attachable to a distal end of the cartridge enabling a first mode of operation. The top cartridge connector is directly removably attachable to the main cartridge connector enabling a second mode of operation.
