ELECTRICAL HEATING NODE FOR HEATING AEROSOL FORMING SUBSTRATE Russian patent published in 2022 - IPC A24F40/40 A24F40/46 A24F40/00 

FIELD: tobacco industry.

SUBSTANCE: group of inventions relates to the tobacco industry, namely to a heating node for heating aerosol forming substrate, an electrically heated aerosol generating device, and an aerosol generating system. The heating node for heating aerosol forming substrate contains a bowl-shaped heating chamber for accommodation of aerosol forming substrate to be heated. The heating chamber is formed by at least a sleeve part and a lower part, which is located at a far end of the heating chamber opposite to an open near end of the heating chamber. The heating node contains the first electrical heater containing at least one first heating element placed along the circumference around the sleeve part for heating the sleeve part to at least the first temperature. The heating node additionally contains the second electrical heater containing at least one second heating element placed on an outer end surface of the lower part for heating the lower part to at least the second temperature.

EFFECT: increase in the efficiency of heating.
