Description
Technical Field
The invention relates to a cooling filter tip and a heating non-combustible cigarette, belonging to the field of cigarette processing and manufacturing.
Background
The heated non-combustible cigarette is closest to the traditional cigarette in the aspects of physiological feeling, psychological feeling, smoking mode and the like, and has good development potential. The fimo international iQOS rapidly occupies 15% of its domestic market since 2014 market in japan, becoming the global largest heating non-combustion tobacco product market. Germany is the second major market, and the united states will exceed germany in 2021; in addition, the third and fourth major markets for such products are swiss and portugal, respectively, which are also the fastest growing markets in both countries. In 5 months 2017, iQOS was marketed in Korea with similar success, and the contemporaneous growth amplitude after marketing has exceeded Japan, becoming the fastest growing market for iQOS. The third quarter of the year Mo Guoji 2017, purportedly shows that iQOS has reached 2.5% in the market share of korea in the short months, proving that the success of this product in Japan is not an exception.
Currently, the iQOS product of Feimo International has been sold in 38 countries in Europe, latin America, asia and Africa, and the global sales of matched cigarettes Heatsticks reaches 362 hundred million. In 2016, 11 months, yingmei tobacco was proposed in Japan as the first electrically heated non-combustible cigarette glo and was planned to expand to about 20 countries at the end of 2018. In month 6 of 2017, the Japanese tobacco company has proposed a bloom Tech. In 11 months 2017, korea corporation pushed out electrically heated non-combustible cigarettes li in the first few, all sold-out once the first few. In general, through years of development innovation, the heated non-combustible cigarettes enter the market innovation burst period, products and consumer groups have a good foundation, the predictable profit margin is high, the development power of tobacco enterprises is strong, and the development is accelerated in a future period of time. From the consumption perspective, along with the increasingly strict cigarette consumption environment and the innovation and upgrading of novel tobacco products, the smoking satisfaction of related products is better, the harm is smaller, the smoking mode is more convenient, and the market space of the heating non-burning type cigarette is rapidly expanded.
According to the investigation data recently issued by European Rui International company, it is shown that the heating of the non-burning product will be the fastest growing product in the next 5 years, the sales will reach $154 billion by 2021, and 20 billion dollars higher than 2016, will reach 691% of increase. Global heating of non-combustion products will increase 691% for the next 5 years. Aiming at the rapid development of novel tobacco, philips Moris tobacco International company, huge funds have been invested in 2017 to build new factories in the east Germany. The company also produces the device and its associated heater bars in italy, swiss and greece. The fimbrian international built a heated cigarette factory with annual energy production of up to 300 million in italy, corresponding to 6% of the sales of the company in europe. The investment in iQOS by Feimo International in 2016 will be 12 billion dollars, and 2017 will be 15 billion dollars. To date, this company has invested in iQOS in excess of 30 billion dollars, and Philips Morris (Philip Morris) has placed bets on new tobacco products with reduced toxicity. The company indicates a desire to phase out traditional cigarettes for the next 10 years. By the end of 2018, the yield of the company's wanbao road heating rod is expected to be 2 times that of the current company, and 1000 hundred million.
The large tobacco companies, including the Fei Mo Guoji, re-design cigarettes aiming at the defects of scalding the flue gas and the like, and adopt different solutions. The matched cigarette Marlboro HeatSticks of the iQOS of the heating non-burning cigarette, such as the one proposed by Feimo, uses embossed gathering PLA film cooling materials in the composite filter rod; glo of Yingmei tobacco is a heating product, and a perforated hard paper hollow tube tip rod is used in an ultrafine Kent cigarette to reduce the temperature of smoke; the lil from KT & G corporation of korea is a central pin type heating product, and the Fit cigarette is cooled by using a woven bundle of PLA fibers.
Related research work is also carried out by various domestic tobacco companies, and the tobacco companies are applied to products thereof. The Sichuan medium smoke is 'wide and narrow', the embossed gathered aluminum foil composite paper is adopted for cooling, and the length of a cooling section is 18mm; the smoke 'MOK' in Hubei uses embossing with the length of 20mm to gather PLA cooling sections; the tobacco "MC" tobacco branch in Yunnan uses 10mm embossing gathering PLA film; the Guangdong middle tobacco 'MU' tobacco branch uses a 23mm starch empty pipe as a cooling section; the south-pass acetic acid technology center developed temperature-reducing type acetate fiber particles. The flue gas cooling effect of the heating non-burning cigarettes in the prior art is improved to a certain extent, but the problem of burning the flue gas is not completely solved.
In addition, as the heating temperature of the heated non-combustible cigarettes is lower, the cracking of tobacco materials is insufficient, the release amount of aroma components in smoke is obviously reduced compared with that of the traditional cigarettes, and if the smoke interception efficiency of the filter rod is high, the taste of the smoke is poorer.

Further, the smoke generating segment is composed of a tobacco rod composed of unordered arrangement of treated tobacco shreds or flakes, or other heating non-burning smoke generating materials.
Compared with the prior art, on one hand, the material forming the columnar structure has poor heat conduction capability, and the heat absorbed by the cooling material is not easy to be quickly transferred to the suction end, so that the burning of a user can be prevented; on the other hand, no matter in a central heating mode or a surrounding heating mode, a large amount of water vapor is generated during the suction of the first three openings, and the high-temperature water vapor enters the oral cavity to be condensed and releases a large amount of heat, so that the scalding sense of the oral cavity (particularly the tongue) is obviously enhanced; in still another aspect, after the cooling material is coated on the surface of the rod, the adsorption capacity of the rod to particulate matters such as tar can be remarkably improved, and meanwhile, the through holes in the rod and gaps between the rod and the rod are beneficial to the passing of smoke without resistance, so that the interception of particulate matters is reduced, and the adsorption loss of particulate matters in the smoke is extremely small during suction, thereby being beneficial to improving the suction experience.
In the invention, the cooling filter tip has the advantages of ensuring the smoke quantity of the smoke, reducing the temperature of the smoke entering the oral cavity and the like, particularly, the cooling section, through the combined design of the rod structure, the type and the dosage of cooling materials, not only can the smoke easily flow out of the smoke section quickly and smoothly, but also the temperature of the high-temperature smoke before entering the oral cavity can be obviously reduced, thereby improving the comfort and satisfaction of smoke suction; the problems of excessive water vapor, small smoke amount and poor taste of the prior heating non-burning cigarettes during the front three-mouth smoking can be solved.
