Abstract
A shisha device comprises a cooling element (13) disposed along an airflow channel to cool an aerosol. The cooling element unit utilizes active cooling and may additionally utilize passive cooling. The cooling element may comprise a conduit (21) comprising a thermally conductive material. The cooling element may be integrally formed with an accelerating element (14) disposed along the airflow channel. Cooling may occur before or during acceleration of the aerosol by the accelerating element. The cooling may contribute to the condensation in the aerosol.
Claims15
A shisha device comprising:
- a vessel defining an interior for housing a volume of liquid, the vessel comprising a head space outlet;
- an aerosol-generating element for receiving an aerosol-forming substrate, the aerosol-generating element in fluid communication with the interior of the vessel via an airflow channel, the airflow channel extending into the interior of the vessel from the aerosol-generating element;
- a cooling element along the airflow channel between the aerosol-generating element and the vessel, the cooling element configured to cool aerosol in the airflow channel that flows through the cooling element and couplable to a power source to provide active cooling to transfer heat away from the airflow channel;
- and
- an accelerating element along the airflow channel between the aerosol-generating element and the vessel, the accelerating element configured to accelerate aerosol in the airflow channel that flows through the accelerating element;
- and,
- a chamber along the airflow channel between the vessel and the accelerating element, the chamber configured to receive aerosol after being accelerated;
- wherein the cooling element is at least partially or entirely disposed between the chamber and the aerosol-generating element.
