Abstract
A shisha device () comprises an aerosol-generating element () for receiving an aerosol-forming substrate (). The shisha device also comprises a vessel () spaced from the aerosol-generating element and defining an interior for housing a volume of liquid. The vessel comprises a head space outlet (). The shisha device also comprises an aerosol conduit () positioned between the aerosol-generating element and the interior of the vessel. The aerosol conduit comprises a proximal end portion defining a proximal opening () positioned to receive airflow from the aerosol-generating element, a distal end portion defining a distal opening () positioned in the interior of the vessel, and a ventilation opening () positioned between the proximal and distal end portions. A ratio between the total aperture area of the ventilation opening and a transverse cross-sectional area of the aerosol conduit positioned proximate to the ventilation opening is at most 1:1000. Applying a negative pressure at the head space outlet causes airflow through the aerosol conduit from the proximal opening to the distal opening and causes airflow through the aerosol conduit from the ventilation opening to the distal opening.
