Problems solved by technology

Although the flue gas cooling effect of heat-not-burn cigarettes using the existing technology has been improved to a certain extent, it has not completely solved the problem of the smoke burning the mouth
[0007] In addition, due to the low heating temperature of heat-not-burn cigarettes, the cracking of tobacco substances is insufficient, and the release of aroma components in smoke is significantly lower than that of traditional cigarettes. If the smoke retention efficiency of the mouth stick is high, the smoke taste will be worse

Embodiment 1

[0047] Such as figure 1 As shown, a heat-not-burn cigarette includes sequentially connected filter section 1, cooling section 2 and smoking section 3, and the filtering section 1 and cooling section 2 form the main part of the cooling tip rod, and the filtering section is composed of cooling and It consists of a special acetate filter rod with low smoke interception, and the cooling section is formed by wrapping a columnar structure formed by a plurality of first rods 201 with the outer packaging layer 4, and the surface of the first rods is coated with a cooling material. The first rod is a cylindrical barrel, and the flue gas flow channel 203 is mainly composed of through holes in the first rod and gaps between the first rods.

[0048] Wherein, the first rod is a round rod with an outer diameter of 0.3 mm.

[0049] The first rod is made of a cellulose paper material with a low absorbent capacity. The quantitative of the cellulose paper is 100g / m 2 .

[0050] The cooling ...

Embodiment 2

[0055] Example 1 was repeated, only changing the outer diameter of the first rod to 0.5 mm. Through comparative research, it was found that the highest flue gas temperature at the inlet was 43°C, which was 20°C lower than that of iQOS; at the same time, the total particulate matter in the flue gas was 16.0 mg / piece, which was 16.0 mg per stick, which was 20°C lower than that of iQOS flue gas. The temperature of the inlet flue gas was significantly reduced, and the amount of smoke at the inlet flue gas was also increased, achieving the effect of lowering the temperature and lowering the retention of flue gas (see Table 1 for the results).

Embodiment 3

[0057] Example 1 was repeated, changing only the outer diameter of the first rod to 0.8 mm. A comparative study found that the maximum flue gas temperature at the inlet was 45°C, which was 18°C ​​lower than that of iQOS; at the same time, the total particulate matter in the flue gas was 16.3 mg / piece, which was 16.3 mg per stick, which was 18°C ​​lower than that of the iQOS flue gas. The phase matter increased by 1.1 mg / stick, the temperature of the inlet flue gas decreased significantly, and the amount of smoke at the inlet flue gas also increased, achieving the effect of lowering the temperature and lowering the retention of flue gas (see Table 1 for results).

Abstract

The invention relates to a cooling holder rod and a cigarette incombustible in heating. The cooling holder rod comprises a cooling section, wherein the cooling section is of a columnar structure formed by M first rods and N second rods, a plurality of through holes penetrating through two ends of each first rod are formed in the first rods, the second rods are solid rods, the surfaces of the firstrods and the surface of the second rods are both coated with a cooling material, M and N are both natural numbers, and the sum of the M and N is greater than or equal to 2. The cooling holder rod hasthe advantages of ensuring smoke amount, reducing the temperature of smoke entering the mouth and the like, especially the cooling section can make smoke easily, quickly and smoothly flow out of a fuming section and can also remarkably the temperature of high-temperature smoke before the smoke is sucked into the mouth by adopting the combined design of the rod structure and the variety and use amount of the cooling material, and accordingly the smoking comfort and satisfaction are improved. The problem can also be solved that water steam is excessive, the smoke amount is small and the taste is poor during first three puffs of an existing cigarette incombustible in heating.

Description

technical field [0001] The invention relates to a cooling nozzle stick and a heat-not-burn cigarette, belonging to the field of cigarette processing and manufacturing. Background technique [0002] Heat-not-burn cigarettes are closest to traditional cigarettes in terms of physiological feelings, psychological perception, and smoking methods, and have good development potential. Since its launch in the Japanese market in 2014, Philip Morris International's iQOS has quickly occupied 15% of its domestic market, becoming the world's largest heat-not-burn tobacco product market. Germany is the second largest market, and the United States will surpass Germany in 2021; in addition, the third and fourth largest markets for this type of product are Switzerland and Portugal, which are also the fastest growing markets. In May 2017, iQOS was launched in South Korea and achieved similar success. After its launch, the growth rate in the same period has surpassed that of Japan, becoming t...
