HEATING SMOKING SET WITH LOW OXYGEN CONTENT, HEATING CIGARETTE WITH LOW OXYGEN CONTENT, LOW-OXYGEN HEATING CIGARETTE UNIT COMPRISING SAID KIT AND CIGARETTE, AND METHOD OF SMOKING LOW-OXYGEN HEATING CIGARETTE Russian patent published in 2025 - IPC A24D1/20 

FIELD: smoking accessories.

SUBSTANCE: group of inventions relates to a heating smoking set with low oxygen content, a heating cigarette, a heating cigarette unit and a method of smoking such a cigarette. Heating smoking set with low oxygen content comprises a heating section with a cavity formed therein to accommodate a cigarette and an element for extracting smoke, which is made separately from the heating smoking set with low oxygen content. Smoke extraction element comprises a hollow smoke extraction cone and a smoke transfer pipe which is fixed or detachably fitted on the periphery of the cone housing of the smoke extraction cone. At the top of the cone and/or the side wall of the conical housing, a conical hole is provided, at least one through hole is provided on the cylindrical side wall of the smoke transfer pipe, and the axial distance from the said at least one through hole to the lower surface of the conical body is less than the distance from the conical hole to the lower surface of the conical body. Due to the use of the Venturi effect and the Coanda effect for extracting smoke, the oxygen content can be reduced, thus, the heating temperature can be significantly increased, which leads to the use of both reconstituted tobacco and conventional cigarette formulas.

EFFECT: due to use of a sealed structure, tobacco residues do not fall out and the smoking set does not require frequent cleaning.
