HEATED SMOKING DEVICE AND SYSTEM FOR HEATING TOBACCO WITHOUT COMBUSTION Russian patent published in 2023 - IPC A24D1/20 

FIELD: tobacco smoking devices and systems.

SUBSTANCE: group of inventions relates to a heated smoking device and a tobacco heating system without combustion. A heated smoking device is proposed, which includes an aerosol-forming substrate section, a cooling section, and a filtration section arranged in series along the length of the heated and smoking devices. The cooling section is for cooling the smoke generated by the aerosol-forming substrate section when heated, and the filtering section is for filtering at least one component in the smoke. The cooling section includes a phase change material, the components in the phase change material have at least two phase change temperatures in the temperature range from 45 to 150°C, and the phase transition temperatures are solid-solid phase transition temperatures or solid-liquid phase transition temperatures. The phase change material is contained in the phase change coating applied to the interior surface of the cooling section housing structure. The cooling section is provided with a number of ventilation holes. The cooling section includes at least two cooling subsections and a number of ventilation holes provided in one of the cooling subsections. The body of at least one of the cooling subsections is made of a hollow cellulose acetate rod.

EFFECT: inventions provide effective reduction of smoke temperature, which is regulated in a range more comfortable for the user.
