Embodiment 1

[0030] Such as figure 1 As shown, a heat-not-burn cigarette filter rod 1 includes a tobacco section 2 and a rod section 3. The rod section 3 includes a cooling part 4, a mouth contact part 5, a heat insulation part, etc., and the heat insulation part is With a hollow structure, the cooling part 4 includes at least one cavity structure 7 with different opening sizes at both ends of the cavity structure 7, wherein the large mouth end faces the tobacco section 2 and the small mouth end faces the mouth contact part 5.

[0031] When the heat-not-burn cigarette filter rod 1 is smoking, insert the tobacco section 2 into the corresponding heating device for heating. After the heating is completed, the mouth touch part 5 is smoked. The smoke enters the heat insulation part from the tobacco section 2 and gathers. Then enter the cooling part 4, and further gather and store in the cooling part 4. Since the cross-sectional area of ​​the cooling part 4 gradually decreases along the flue gas flo...

Embodiment 2

[0033] Such as figure 1 As shown, a heat-not-burn cigarette filter rod 1 includes a tobacco section 2 and a rod section 3. The rod section 3 includes a cooling part 4, a mouth contact part 5, a heat insulation part, etc., and the heat insulation part is A hollow structure made by cutting the hollow nozzle rod, the cooling part 4 includes at least one cavity structure 7 with different opening sizes at both ends of the cavity structure 7, wherein the large mouth end faces the tobacco section and the small mouth end faces the mouth contact part.

[0034] When the heat-not-burn cigarette filter rod 1 is smoking, insert the tobacco section 2 into the corresponding heating device for heating. After the heating is completed, the mouth touch part 5 is smoked. The smoke enters the heat insulation part from the tobacco section 2 and gathers. Then enter the cooling part 4, and further gather and store in the cooling part 4. Since the cross-sectional area of ​​the cooling part 4 gradually dec...

Embodiment 3

[0036] Such as figure 2 As shown, a heat-not-burn cigarette filter rod 1 includes a tobacco section 2 and a rod section 3. The rod section 3 includes a cooling part 4, a mouth contact part 5, a heat insulation part, etc., and the heat insulation part is Hollow structure, the cooling part 4 includes at least one cavity structure 7, the two ends of the cavity structure 7 have different opening sizes, wherein one end of the large mouth faces the tobacco section, and the end of the small mouth faces the mouth contact part, the cavity of the cooling part 4 The structure 7 is formed by filling the heat-absorbing material in a spiral loose roll shape, and the heat-absorbing material is polylactic acid.

[0037] When the heat-not-burn cigarette filter rod 1 is smoked, the tobacco section 2 is inserted into the corresponding heating device for heating. After the heating is completed, the mouth touch part 5 is smoked, and the smoke flows from the tobacco section 2 into the heat insulation...

Abstract

The invention provides a heat-not-burn cigarette filter stick and relates to the technical fields of processing and manufacturing of cigarettes. The heat-not-burn cigarette filter stick comprises a tobacco section and a holder bar section, wherein the holder bar section comprises a cooling part, a mouth contact part and the like; the cooling part at least comprises a cavity structure, the sizes ofopenings in two ends of the cavity structure are different, the big opening end faces towards the tobacco section, and the small opening end faces towards the mouth contact part. In the smoking process, the tobacco section is heated, and the smoke flows through the tobacco section, is gathered and cooled at the cooling part and then flows into the mouth contact part. By adopting the heat-not-burncigarette filter stick, the concentration of the smoke is effectively increased, the temperature of the smoke is decreased, and the smoking quality of cigarettes is improved.

Description

Technical field [0001] The invention relates to the technical field of cigarette processing and manufacturing, in particular to a heat-not-burn cigarette filter rod. Background technique [0002] With the improvement of tobacco control situation and smokers’ health awareness, traditional cigarettes will crack and release a large amount of harmful substances during the combustion process due to their high burning temperature, so their development has been greatly restricted. The tobacco industry depends on traditional cigarettes for profit growth. The space is gradually reduced. [0003] Heat-not-burn tobacco products are products that best reflect the original taste of tobacco and are less harmful to the body. They are heated by electronic equipment. The tobacco does not participate in the combustion. The temperature during heating is between 250-300°C, and the highest temperature does not exceed 350°C. The burning temperature of traditional cigarettes can reach 800℃, so it can re...
