Description

Cooling filter tip and cigarette
Technical Field
The invention relates to a cooling filter tip and a cigarette, and belongs to the technical field of cigarettes.
Background
The cigarette which is not combusted by heating is closest to the traditional cigarette in the aspects of physiological sensation, psychological perception, smoking mode and the like, and has good development potential. The iQOS of Feimo world rapidly occupies 15% of the domestic market since the release in the Japanese market in 2014, and becomes the largest heating non-combustible tobacco product market in the world. Germany is the second largest market, and the united states will exceed germany in 2021; in addition, the third and fourth major markets for such products are swiss and portuguese, respectively, which are also the fastest growing markets. In 5 months 2017, iQOS was marketed in Korea with similar success, and the increase in synchronization after marketing has surpassed that in Japan, becoming the fastest growing market for iQOS. It is known that the third quarter of 2017 in fimo international show that iQOS market share in Korea reaches 2.5% in as short as several months, proving that the success of the product in Japan is not an exception.
Currently, the iQOS product of Feimo is sold in 38 countries in Europe, Latin America, Asia and Africa, and the global sales of the matched cigarettes, Heatsticks, reaches 362 hundred million. In 2016, 11 months, the first electrically heated non-combustible cigarette glo was introduced by tobacco in the united states, and the expansion to about 20 countries was planned at the end of 2018. In 6 months 2017, the company Nicotiana Japan introduced Ploom Tech. In 11 months in 2017, the electrically heated non-combustible cigarette li was introduced by korea corporation in seoul, and all the cigarettes were sold out once the first batch appeared. Generally, through years of development and innovation, the cigarette without combustion after being heated enters the market innovation outbreak period, products and consumer groups have better foundation, the foreseeable profit rate is higher, the development power of tobacco enterprises is very strong, and the development of the cigarette is accelerated in the future. From the consumption perspective, along with the increasingly strict cigarette consumption environment and the innovation and the upgrade of novel tobacco products, the smoking satisfaction of related products is better, the harmfulness is smaller, the smoking mode is more convenient, and the market space for heating non-burning cigarettes is rapidly expanded.
According to recent survey data published by eurui international company, it is shown that heating non-combustible products will be the fastest growing product in the next 5 years, and the sales amount will reach $ 154 billion by 2021, and reach 691% increase higher than $ 20 billion in 2016. The global heating of non-combustible products will increase 691% in the next 5 years. Aiming at the rapid development of new tobacco, Philips Morris tobacco International, 2017 has invested a large amount of capital to build a new factory in east Germany. The company also produces the device and its associated heating rods in italy, switzerland and greece. Feimo has built a heated cigarette factory in Italy with an annual capacity of 300 million cigarettes, corresponding to 6% of the company's sales in Europe. Femo international will invest an iQOS of $ 12 billion in 2016 and increase to $ 15 billion in 2017. To date, this company has invested over 30 billion dollars in iQOS, and Philip Morris corporation (Philip Morris) has placed bets on new tobacco products with reduced toxicity. The company indicates that it is expected to phase out traditional cigarettes within the next 10 years. By 2018, the yield of the heating rod in the Wanbao road of the company is expected to be 2 times that of the current heating rod, and the yield reaches 1000 hundred million.
In order to overcome the defects of over-burning of smoke and the like, the tobacco companies including Feimeo nations re-design cigarettes and adopt different solutions. For example, the heated non-burning cigarette iQOS matched with Marlboro HeatSticks proposed by Felmo International uses embossing gathered PLA film cooling material in a composite filter tip; glo of Yingmei tobacco is a surrounding heating product, and a perforated hard paper hollow nozzle rod is used in the superfine Kent cigarette to reduce the smoke temperature; the finished cigarette is manufactured by heating a product with a center pin, which is a lil product from KT & G, Korea corporation, and the finished cigarette is cooled by using a woven bundle of PLA fibers.
Related research work is also carried out by various domestic cigarette companies, and the tobacco products are applied to the tobacco products. The width of the Sichuan Zhongyan is reduced by adopting embossed gathered aluminum foil composite paper, and the length of the reduced temperature section is 18 mm; the MOK cigarette in Hubei uses embossing gathering PLA cooling section with length of 20 mm; the 'MC' cigarette in Yunnan province uses 10mm of embossing gathered PLA film; the MU cigarette in Guangdong uses a starch hollow pipe with the diameter of 23mm as a cooling section; the Nantong acetic acid technology center develops cooling type acetate fiber particles. Although the smoke cooling effect of heating the non-burning cigarettes in the prior art is improved to a certain extent, the problem that the mouth is scalded by smoke is not completely solved.
In addition, the heating temperature for heating the non-combustible cigarette is lower, so that the cracking of tobacco substances is insufficient, the release amount of aroma components in smoke is obviously reduced compared with that of the traditional cigarette, and if the smoke interception efficiency of the filter rod is high, the taste of the smoke is poorer.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a cooling filter tip and a cigarette, which are used for reducing the temperature of a smoke inlet and further improving and promoting the smoking experience of the cigarette while basically not reducing particulate matters in the smoke.
In order to solve the technical problems, the technical scheme of the invention is as follows:
a cooling mouth rod comprises a cooling section, wherein a plurality of channels penetrating through two ends of the cooling section are arranged in the cooling section, and the ratio of the total cross sectional area of the channels to the cross sectional area of the cooling section is 1-9:10, generally 2-9:10, and preferably 3-8: 10; the side wall of the channel is coated with a cooling material;
