Background technique

Heated cigarettes, also known as low-temperature cigarettes, are a new type of tobacco product that uses a special heat source to heat cut tobacco, and the nicotine and aroma substances in the cut tobacco are volatilized to generate smoke to meet the needs of smokers. The filter rod of the heated cigarette has the functions of filtering the smoke, reducing the temperature of the smoke, balancing the delivery of the smoke, and adding aroma-carrying substances to enhance the fragrance. At present, various tobacco companies have various specifications of heated cigarette products on the market, and their filter rods are also in various forms, all of which have certain functions such as cooling or aroma.

However, the design of cigarettes for the closed anaerobic heating cup smoking set is relatively rare, because the heating temperature of the closed anaerobic heating cup smoking set is 30℃-60℃ higher than that of the traditional heating smoking set. The cooling and aroma-enhancing effects also put forward higher requirements. At the same time, when the temperature rises, the shape and quality of the smoke will also change accordingly, and the filter rod section of the cigarette needs to be redesigned.

Sample 1.

Comparative Example 1

In this comparative example, referring to the connection sequence of the quaternary composite filter rod of test sample 1, the quaternary composite filter rod of comparative sample 1 was prepared by using the same materials and length dimensions as those of test sample 1 for each section. Among them, the hollow section 2 in the test sample 1 is adjusted to a solid structure, the hollow tube cavity is not retained, and the cooling aroma-carrying section 3 is not filled with any aroma-carrying material, and is wrapped and connected with the smoking material section on the side near the support section with pine paper. , the support section 4 is not perforated, and the cigarette comparative sample 1 is obtained.

Comparative Example 2

In this comparative example, referring to the connection sequence of the quaternary composite filter rod of test sample 1, the quaternary composite filter rod of comparative sample 2 was prepared by using the same material and length dimension as those of test sample 1 for each section. Among them, the hollow section 2 in the test sample 1 is adjusted to a solid structure, and the hollow tube cavity is not retained. Cigarette Comparative Sample 2 was prepared.

Comparative Example 3

In this embodiment, referring to the connection sequence of the quaternary composite filter rod of test sample 1, the quaternary composite filter rod of comparative sample 3 is prepared by using the same materials and length dimensions as those of test sample 1 for each section. Among them, the hollow section 2 in the test sample 1 is adjusted to a solid structure, and the hollow tube cavity is not retained. Cigarette Comparative Sample 3 was prepared by retaining the same position and number of perforated structures.

Example 4

According to Yunnan China Tobacco Enterprise Standard "Sensory Evaluation Method for New Cigarettes" (Q/YNZY.J04.022-2015), smoking evaluation experts were invited to use the same heat-not-burn smoking device to evaluate the smoking of the example samples. See Table 1 below.

According to the results of the evaluation, it was found that:

The comprehensive smoking effect of test sample 1 is the best, and the performance of smoke volume, smoke temperature, aroma and fragrance is the best, especially the fusion effect of tobacco original incense and popped pearl incense is the best.

In comparison sample 1, since the hollow section 2 has no hollow cavity and explosive beads, the smoke volume and aroma and fragrance performance are not good, the smoke temperature is also high, the suction resistance is too large, and the suction sensory performance is poor.

The difference in structure between the comparative sample 2 and the comparative sample 3 is the perforation, and the main difference in the suction experience is the different flue gas temperature. Therefore, the flue gas temperature can be reduced after the filter rod support section 4 is perforated.

This is because the comparison sample 2 and the comparison sample 3 do not have a hollow cavity in the hollow section 2, and the fusion of the tobacco original incense and the fried pearl incense shows an obvious sense of layering and peeling.

Therefore, it can be seen from the samples of the examples that the beneficial effects of the present invention are relatively significant.

The above are only specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art can easily think of changes or substitutions within the technical scope disclosed by the present invention. should be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
