HOOKAH DEVICE WITH ACTIVE COOLING, PROVIDING IMPROVED AEROSOL CHARACTERISTICS Russian patent published in 2022 - IPC A24F1/30 

FIELD: tobacco industry.

SUBSTANCE: invention relates to hookah devices, and more specifically to hookah devices that heat aerosol forming substrate without burning substrate. The proposed hookah device contains a vessel defining the inner part to accommodate a volume of liquid, while the vessel contains an outlet element of a free space; an aerosol generating element to accommodate aerosol forming substrate; a cooling element along a channel for air flow between the aerosol generating element and the vessel; and an accelerating element along the channel for air flow between the aerosol generating element and the vessel. In this case, the aerosol generating element is in communication via fluid with the inner part of the vessel by means of the air flow channel, while the air flow channel extends into the inner part of the vessel from the aerosol generating element. The cooling element is made with the possibility of cooling aerosol in the air flow channel, which flows through the cooling element, and can be connected to a power source to provide active cooling for heat transfer from the air flow channel. The accelerating element is made with the possibility of acceleration of aerosol in the air flow channel, which flows through the accelerating element.

EFFECT: creation of a hookah device that generates satisfactory amount of visible aerosol and/or the total mass of aerosol with sufficiently low drag resistance, while heating substrate so that no combustion by-products occur.
