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

[0050] Such as figure 1 As shown, a cooling nozzle rod includes a cooling section 2, and the cooling section 2 has a plurality of passages 203 passing through both ends of the cooling section. The ratio of the total cross-sectional area of ​​the several passages 203 to the cross-sectional area of ​​the cooling section 2 is 1-9:10; the sidewall of the channel 203 is coated with a cooling material;

[0051] The cooling material includes at least two of low molecular weight PEG, medium molecular weight PEG and high molecular weight PEG. A heat-not-burn cigarette, comprising a filtering section 1, a cooling section 2 and a smoking section 3 connected in sequence, the filtering section 1 and the cooling section 2 constitute the main part of the cooling tip stick, the filtering section is composed of a cooling and low-smoke It is composed of retained special acetate filter rods, and the cooling section is formed by wrapping a columnar structure formed by a plurality of first rods 2...

Embodiment 2

[0059] 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

[0061] 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 filter rod and a cigarette. The cooling filter rod comprises a cooling section; a plurality of passages running through both ends of the cooling section are formed in the cooling section; a ratio of a total cross section area of the plurality of passages to a cross section area of the cooling section is 1-9 to 10; the side walls of the passages are coated with acooling material; and the cooling material comprises at least two of low-molecular-weight PEG (polyethylene glycol), a medium-molecular-weight PEG and high-molecular-weight PEG. The cooling filter roddisclosed by the invention has the advantages of ensuring a smoke volume of fume, reducing a temperature of the fume entering an oral cavity and the like; by design of a cooling rod structure and thecooling material composition, not only can the fume be easy to rapidly and smoothly flow out of a fuming section, but also the temperature of the high-temperature fume before the fume enters the oralcavity can be obviously reduced, so that comfort and satisfaction of smoking are promoted; and problems of excessive water vapor, small smoke volume and bad taste, which are generated when an existing HNB (Heat Not Burning) cigarette is smoked by first three mouths, also can be solved.

Description

technical field [0001] The invention relates to a cooling nozzle stick and a cigarette, belonging to the technical field of cigarettes. 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 the fastest growing market for iQ...
