ELECTRONIC CIGARETTE CARTRIDGE (VERSIONS) Russian patent published in 2025 - IPC A24F40/46 A24F40/42 A24F40/465 

FIELD: smoking accessories.

SUBSTANCE: disclosed is group of inventions, including versions of electronic cigarette cartridge. Cartridge contains a flow direction section, a smoke generation substrate section, a hollow section and a filter section, installed in series in the enveloping element. Enveloping element represents a hollow paper cylinder. Flow directing section is located at the female element far end. Flow directing section is formed by the internal cylindrical wall of the enveloping element and the first separating element. First separating element is adjacent or glued to the inner cylindrical wall of the enveloping element and separates the flow direction section from the smoke-generating substrate section. In the section of the smoke-generating substrate there is a smoke-generating substrate and an inductor. Smoke production substrate is represented by granules produced of tobacco and/or non-tobacco plants. Inductor is made from solid plate-like or cylindrical magnetic material by at least single bending. Longitudinal section of the inductor in the cigarette has not completely closed geometrical shape. Inductor has one end part and two side parts. One closed end of the inductor is an end part, and two open sides are side parts. Inductor is located in the smoke-generating substrate and is surrounded by the smoke-generating substrate. Hollow section is jointly formed by second separating element, inner cylindrical wall of enveloping element and filter section. Second separating element is adjacent or glued to the inner cylindrical wall of the enveloping element and separates the hollow section from the smoke-generating substrate section. Filter section is located at the female element proximal end. Filter section is made of a material capable of filtering and cooling smoke. First separating element and second separating element are flexible sheet material, their longitudinal section has ]-shaped form or [-shaped form.

EFFECT: higher quality of heating and providing an electronic cigarette cartridge suitable for both insert-type heaters and electromagnetic induction heaters of circular heating.
