Cooling filter rod, fuming product and application

Abstract

The invention relates to a cooling filter rod, a fuming product and the application. 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; and the inner surfaces of the passages are coated with a cooling material. The cooling filter rod is characterized in that the cooling material comprises an inorganic phase-change material; and the inorganic phase-change material comprises at least one of Na2HPO4.12H2O, Na2CO3.10H2O, CH3COONa.3H2O, CaCl2.4H2O and Na2SO4.10H2O. The cooling filter rod disclosed 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; particularly, the cooling section, by combined design of a cooling rod structure, the type of the cooling material and a use quantity of the cooling material, not only can make the fume easy to rapidly and smoothly flow out of a fuming section, butalso can obviously reduce the temperature of the high-temperature fume before the fume enters the oral cavity; the smoke volume is sufficient and the temperature is proper, 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 threemouths, also can be solved.

Description

technical field [0001] The invention relates to a cooling nozzle stick, a smoking product and its application, and belongs to the field of smoking products. Background technique [0002] The global new tobacco product market is growing rapidly and developing rapidly. In 2010, the global sales of new tobacco products were only 1.004 billion US dollars, which increased to 17.750 billion US dollars in 2017, with an average annual growth rate of 50.7%. Among them, the global sales of e-cigarettes in 2010 were only US$1.003 billion, which increased to US$11.441 billion in 2017, with an average annual growth rate of 41.6%. It has increased to 6.309 billion US dollars, with an average annual growth rate of 469.5%. The consumer groups of new tobacco products are already quite large. In 2017, there were 47 million global consumer groups, more than 37 million e-cigarette consumers, and about 10 million heat-not-burn cigarette consumers. Among them, Philip Morris International iQOS...

Problems solved by technology

According to Euromonitor International's estimates, the global sales of traditional cigarettes will continue to decline at a rate of 1-2% in the next five years, and sales will be difficult to maintain through price increases; Within the scope, the growth has reached the limit

[0004] At present, the mainstream heat-not-burn cigarettes on the market include Philip Morris’ iQOS and British American Tobacco’s glo. The temperature entering the mouth through the filter section will be higher than the burning temperature of ordinary cigarettes, resulting in overheating of the smoke at the entrance, and there is still a big gap with traditional cigarettes in terms of smoking experience and smoking experience.

[0005] The existing technology mainly uses phase-change cooling materials to cool the high-temperature flue gas that flows vertically. For example, the material of the cooling section of iQOS is mainly polylactic acid (PLA) sheets that are wrinkled, pleated, gathered and folded. The limitation of length and phase-change cooling material, and the relatively fast flow rate of smoke make it difficult to cool down the material; the lateral heat transfer of overheated smoke through the mouthpiece makes consumers feel like burning their lips when they smoke.

In addition, PLA flakes, a phase-change cooling material, will melt when exposed to high-temperature flue gas, which will block the flue gas passage, affect the cooling effect of the material, and even lead to a significant reduction in the amount of smoke
