Multi-section type heating non-combustion cigarette

Abstract

The invention discloses a multi-section type heating non-combustion cigarette, comprising sequentially connected cooling filter section (4), first hollow tube section (3), smoke section (2) and secondhollow pipe section (1), from a proximal lip end to a distal lip end, wherein the cooling filter section (4), the first hollow tube section (3), and the second hollow pipe section (1) are coated witha thin film; a heater having a diameter greater than 70% of the diameter of the smoke section (2) can be accommodated in the second hollow pipe section (1); the length of the heater is smaller than the length of the second hollow pipe section (1); the smoke section (2) comprises one or a mixture of disorderly oriented recycled tobacco leaves or conventional cigarette tobacco shreds, and the outerfilm of the smoke section (2) and the second hollow pipe section (1); and the second hollow pipe section is arranged at one end of the smoke section away from the near lip end, and the second hollowpipe section can accommodate a heater with a diameter larger than 70% of the diameter of the smoke section 2, thereby greatly increasing the heating area of the heater, improving the utilization efficiency of heat energy, shortening the heating speed of the cigarette branch, and simultaneously increasing the amount of smoke.

Description

technical field [0001] The invention belongs to the technical field of new tobacco, and in particular relates to a multi-stage heat-not-burn cigarette. Background technique [0002] With the improvement of living standards, people pay more and more attention to their own health problems. In recent years, there has been a high degree of attention to smoking health problems. In order to meet the changing consumer demand, major enterprises at home and abroad have developed various completely hollow tobacco products that replace traditional cigarettes. Among these growing fully hollow tobacco products, e-cigarettes and heat-not-burn cigarettes are among the best. [0003] As an expanded application of electronic products in the tobacco industry, e-cigarettes have the advantage of strong variability in taste, and can adjust the smoke flavor by adjusting the components of e-liquid. The taste, especially the sense of heat, is still different from that of traditional cigarettes th...

AI Technical Summary

Problems solved by technology

Currently marketed heat-not-burn cigarettes are mainly divided into two types: central heating (such as IQOS) and circumferential heating (such as GLO) according to the heating position; A series of troubles have arisen in the production and consumption of cigarettes: ①The central heating type heat-not-burn cigarettes must be arranged in an orderly manner along the radial direction of the cigarettes because the heater must be inserted into the substrate (usually reconstituted tobacco leaves) that produce atomized smoke , the most typical is the IQOS series products of Philip Morris; in addition, a support section (usually a hollow tube in the center) must be set at the rear end of the matrix to prevent the heater from being inserted into the back of the matrix section. ②Circumferentially heated heat-not-burn cigarettes, because the heater is located on the periphery of the cigarette, the smoke cannot directly pass through the heater, and the heat energy utilization rate is low, resulting in poor heating effect and the difference between the smoke and the traditional smoke , and ultimately affect the sensory quality of smoke; ③Cigarettes consumed by the two heating methods cannot be mixed, resulting in consumers’ excessive investment in heating devices (smoking sets), which reduces consumers’ enthusiasm for consumption

In general, the current centrally heated heat-not-burn cigarettes have too complicated design requirements, while the smoke quality of circumferentially heated heat-not-burn cigarettes has certain defects, and the two types of cigarettes cannot be mixed
