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.

Abstract: An aerosol generator configured to generate an aerosol from an aerosol-forming substrate is provided, the aerosol generator including: a non-thermal aerosol-generating element configured to aerosolise an aerosol-forming substrate; at least one air inlet; at least one air outlet; a chamber between the air inlet and the air outlet, the non-thermal aerosol-generating element being arranged in the chamber and being further configured to release aerosolised aerosol-forming substrate into the chamber; an airflow path extending through the chamber between the air inlet and the air outlet, via the non-thermal aerosol-generating element; and a side wall circumscribing the non-thermal aerosol-generating element, the side wall having a curved surface defining a curved surface of the chamber, the air inlet extending through the side wall and being configured to direct air into the chamber in a direction tangential to the curved surface of the chamber.

Abstract: A method includes generating an aerosol by heating, without combusting, an aerosol generating substrate (300) in a shisha device (100). The method further includes introducing at least one aerosol condensation particle to an airflow path (103) of the shisha device. The airflow path (103) carries the aerosol generated by the aerosol generating substrate to an outlet (104) of the shisha device for delivery to a user.

Abstract: A cartridge for an aerosol-generating system is provided, the cartridge containing: a first liquid formulation including at least one of water and one or more water-miscible solvents; and a second liquid formulation including one or more water-immiscible solvents having a water solubility at 20° C. of less than or equal to about 100 mg/ml, in which at least one of the first liquid formulation and the second liquid formulation comprises nicotine. An aerosol-generating system is also provided, including the cartridge; and an aerosol-generating device including one or more atomizers configured to generate an aerosol from the first liquid formulation and the second liquid formulation contained in the cartridge.

Abstract: An aerosol-generating device is provided, including: a first storage portion; a first liquid aerosol-forming substrate contained within the first storage portion; an electrospray device to generate a first aerosol from the first liquid aerosol-forming substrate, the electrospray device including a nozzle to receive the first liquid aerosol-forming substrate from the first storage portion, and a voltage circuit including a circuit ground, the voltage circuit to apply a voltage difference between the first liquid aerosol-forming substrate and the circuit ground; a second storage portion; a second liquid aerosol-forming substrate contained within the second storage portion; a heater to heat second liquid aerosol-forming substrate from the second storage portion; and a mixing chamber in fluid communication with the nozzle and the heater, the heater being downstream of the nozzle.
