This abstract first appeared for US patent application 18701632 titled 'AEROSOL-GENERATING DEVICE HAVING A RESTRICTED AIRFLOW PATHWAY



Original Abstract Submitted

An aerosol-generating device is provided, including: an air inlet; a cavity configured to receive at least part of an aerosol-generating article; and an airflow channel defining an airflow pathway extending between the air inlet and the cavity, the airflow channel including a first airflow channel portion and a second airflow channel portion, a cross-sectional area of the airflow pathway in the first airflow channel portion being less than a cross-sectional area of the airflow pathway in the second airflow channel portion such that the aerosol-generating device is configured to restrict airflow in first airflow channel portion, and a resistance-to-draw through the airflow channel being between 25 millimetres of water gauge and 70 millimetres of water gauge. An aerosol-generating system including the aerosol-generating device and an aerosol-generating article is also provided.
