Description
Technical Field
The invention belongs to the field of novel tobacco smoking sets, and relates to an aerosol generation method for multi-section heating non-combustible cigarettes.
Background
The combustion temperature of the traditional cigarette is about 900 ℃, smoke containing harmful chemical components (such as polycyclic aromatic hydrocarbons) can be generated in the combustion process, and the environmental pollution can be caused. In recent decades, various tobacco companies in the world have developed new generations of tobacco products or tobacco substitutes, and it is desired to minimize the harm caused by tobacco while satisfying the needs of consumers. The cigarette is heated (the temperature is lower than 500 ℃) instead of burning tobacco to bake out the flavor substances in the tobacco, so that harmful substances and side stream smoke generated by high-temperature burning of the cigarette are not generated, and the cigarette is one of important development directions of the tobacco industry in the future.
The cigarette without burning is heated to generate smoke by heating the loaded spice loaded on the tobacco sheet, and the generation principle of the cigarette has certain similarity with that of the traditional cigarette, so the acceptance of the smoke taste is better. The current market-oriented non-burning cigarette heating is mainly divided into a central heating type (such as IQOS) and a circumferential heating type (such as GLO) from a heating position; however, both of these types of cigarettes have some drawbacks that cause them to be a series of troubles in production and consumption: firstly, because a central heating type non-burning cigarette is inserted into a heater, a substrate (usually reconstituted tobacco) for generating atomized smoke is required to be orderly arranged along the radial direction of the cigarette, and most typically IQOS series products of Femo company; in addition, a support section (usually a central hollow round tube) must be provided at the rear end of the substrate to prevent backward movement of the substrate section that might be caused by heater insertion; secondly, the circumferential heating type heating non-combustible cigarette has poor heating effect due to the fact that the heater is located on the periphery of the cigarette, smoke cannot directly pass through the heater, the heat energy utilization rate is low, the difference between the smoke and the traditional smoke is caused, and the sensory quality of the smoke is finally influenced; and thirdly, cigarettes consumed by the two heating modes cannot be mixed, so that the investment of a consumer on a heating device (smoking set) is overlarge, and the consumption enthusiasm of the consumer is reduced. In general, the design requirements of the existing central heating type non-combustion heating cigarette are too complex, the smoke quality of the circumferential heating type non-combustion heating cigarette has certain defects, and the two cigarettes cannot be used in a mixed manner.
PM corporation has moved forward in the world in this research area, and its patents on heating means design for a non-combustible cigarette smoking device cover both central heating and circumferential heating of a non-combustible cigarette.
The development of Chinese non-combustible heating cigarettes is increasingly popular, but the following two disadvantages exist in general: firstly, the heating mode is limited by the patent barriers of PM company, and there are few innovative smoking method designs which are really practical; secondly, under the guidance of the existing PM company products, the design of domestic heating non-burning cigarettes basically follows the structural mode, and the real Chinese style cigarettes are few. However, as China goes deeper in this respect, products which replace PM company filled smoking substrates with hollow tubes loaded with smoke generating agents have recently appeared in China; the method provides a chance for breaking through the patent blockade of PM company for the design of a smoking method for heating non-burning cigarettes in China. The invention provides an aerosol generating method for multi-section heating of non-combustible cigarettes.

In the preferred embodiment of the present invention, the multi-stage heated non-burning cigarette 5 is placed in the cigarette accommodating chamber 3, the heater 6 is located in the second hollow tube section 54, and heating is performed by controlling the controller 4, and when the heating temperature reaches a predetermined value, smoking can be started. The flow of the air flow 7 during the suction is shown in the attached figure 3, the air flow 7 flows through the outer wall 8 of the cigarette accommodating cavity and flows into the hollow cavity of the cigarette through the bottom of the heater 6; the cigarettes are heated sufficiently by the heater, and the air flow 7 heats the cigarettes by a large amount of hot air due to the larger area in direct contact with the heater 6, so that the efficiency of generating aerosol is higher, and a large amount of aerosol reaches the oral cavity of a consumer after passing through the filter section of the cigarettes.
The invention relates to a multi-section heating non-combustible cigarette 5, which comprises a cooling filter section 51, a first hollow pipe section 52, a smoking section 53 and a second hollow pipe section 54 which are sequentially connected from a near lip end to a far lip end, wherein films wrap the outside of the cooling filter section 51, the first hollow pipe section 52, the smoking section 53 and the second hollow pipe section 54, the second hollow pipe section 54 can accommodate a heater 6 with the diameter being 70% larger than that of the smoking section 53, the length of the heater 6 is smaller than that of the second hollow pipe section 54, and the smoking section 53 comprises one or a mixture of random oriented reconstituted tobacco or traditional cigarette tobacco.

In a preferred embodiment of the present invention, the cooling filter stage 51 has a three-dimensional net structure or a polymer rod structure with through holes formed by foaming using a foaming technique.
In a preferred embodiment of the present invention, the cooling filter segment 51 is a three-dimensional network structure of polylactic acid tow with a longitudinal porosity of 50% to 90%. The cooling filter segment 51 mainly plays a role of cooling and filtering smoke, and may be a tow segment of a three-dimensional net structure (such as a filter stick structure of a traditional filter tip) processed by tows such as Polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polyethylene terephthalate (PET), polylactic acid (PLA), Cellulose Acetate (CA) and the like, or a polymer rod (such as a popcorn structure) with through holes formed by foaming through a foaming technology; the cooling filter stage 51 has a certain longitudinal porosity.
"longitudinal porosity" cools a measure of the space in the cross-section of the filter segment 51 not filled by the tow. For example, if 50% of the area of the cross-section of the cooling filter segment 51 is not filled with tow or foam, the porosity will be 50%; similarly, if the cross-section is completely filled with tow or foam, the porosity of the section is 0%.
