Description

一种用于加热不燃烧卷烟的烟支A cigarette used for heating non-burning cigarettes 技术领域Technical field
本发明涉及加热不燃烧卷烟领域，具体涉及一种用于加热不燃烧卷烟的烟支。The invention relates to the field of heat-not-burn cigarettes, in particular to a cigarette used for heat-not-burn cigarettes.
背景技术Background technique
加热不燃烧卷烟利用外部热源对烟草薄片进行加热，烟草只加热不燃烧就可得到烟气和烟碱的释放，烟草温度远远低于传统卷烟，可以减少烟草高温燃烧裂解产生的有害成分，烟气有害化学成分和毒性大幅降低；同时侧流烟气大幅降低，降低二手烟对非吸烟人群的危害。Heat-not-burn cigarettes use an external heat source to heat the tobacco flakes. The tobacco can be heated and not burned to obtain the release of smoke and nicotine. The temperature of the tobacco is much lower than that of traditional cigarettes, which can reduce harmful components produced by high-temperature combustion and pyrolysis of tobacco. The harmful chemical composition and toxicity of the gas are greatly reduced; at the same time, the sidestream smoke is greatly reduced, reducing the harm of second-hand smoke to non-smokers.
加热不燃烧卷烟对烟草加热的温度一般控制在400℃以下，在250℃～350℃的条件下达到雾化温度，高温雾化烟气通过滤嘴段进入到口腔中的温度会高于传统卷烟烟气的温度。研制合适烟气温度、释放充足烟气量的烟支结构是电加热加热不燃烧卷烟的关键。Heating non-burning cigarettes generally control the heating temperature of tobacco below 400℃, and reach the atomization temperature at 250℃～350℃. The temperature of high-temperature atomized smoke entering the mouth through the filter section will be higher than that of traditional cigarettes. The temperature of the gas. The development of a cigarette structure with suitable flue gas temperature and sufficient amount of flue gas is the key to heating cigarettes without burning.
目前，现有技术中加热不燃烧卷烟烟支都采用了多段式的滤棒对烟芯段产生的烟气进行处理，其滤棒包括支撑段，冷却段，滤嘴段，其中为了减少滤棒对气溶胶的吸附，减少滤棒对气溶胶产生段产生的烟气的截留，支撑段主要采用空管结构，例如中空纸管或中空醋酸纤维棒等。At present, the heat-not-burn cigarettes in the prior art all use multi-section filter rods to process the smoke generated by the core section. The filter rods include a support section, a cooling section, and a filter tip section. The adsorption of aerosols reduces the interception of the smoke generated by the aerosol generation section by the filter rod. The supporting section mainly adopts a hollow tube structure, such as a hollow paper tube or a hollow cellulose acetate rod.
中空纸管是用两至三层纸质基材叠合加工制成，纸质基材的材料特性限制了纸质空管的管壁厚度，一般只能在0.02-0.05mm，管壁厚度太小就会造成纸质空管的支撑性不足，经过切刀时会产生较大形变且无法回弹，严重影响生产效率和产品质量。The hollow paper tube is made of two to three layers of paper substrates. The material characteristics of the paper substrate limit the thickness of the tube wall of the paper hollow tube. Generally, it can only be 0.02-0.05mm. If it is small, it will cause insufficient support of the paper empty tube, which will deform and fail to rebound when passing through the cutter, which will seriously affect production efficiency and product quality.
中空醋酸纤维棒就是用普通醋酸纤维丝束通过滤棒成型机制成，醋酸纤维丝束本身存在高吸附性，且温度过高就会产生塌陷并释放出酸味、焦味气息，由于支撑段是高温气溶胶经过的第一站，中空醋纤棒不仅对气溶胶产生吸附还会释放出负面气息，影响加热不燃烧制品的吸味。The hollow cellulose acetate rod is made of ordinary cellulose acetate tow through the filter rod forming machine. The cellulose acetate tow itself has high adsorption, and if the temperature is too high, it will collapse and release a sour and burnt smell. Because the support section is high temperature The first stop where the aerosol passes, the hollow fiber acetate rod not only adsorbs the aerosol, but also releases a negative atmosphere, which affects the taste of heat-not-burn products.
而冷却段的目的在于降低烟芯段产生的烟气的温度，使其更加容易入口，现有技术中采用聚拢的聚乳酸材料为冷却段，其仍然存在以下问题：1、在对烟芯段产生的烟气降温的同时对烟气吸附大，且还会阻留部分烟气，导致烟气通过量低；2、聚乳酸材料具有热塑性，受热容易发生形变，导致冷却段塌陷，从而影响冷却段对烟支的支撑性能；3、烟支滤棒结构复杂，生产成本高；4、冷却段载 香需要在烟支冷却段制备完成后单独进行，工艺过程复杂，成本高。The purpose of the cooling section is to reduce the temperature of the flue gas generated in the core section to make it easier to enter. In the prior art, the gathered polylactic acid material is used as the cooling section, which still has the following problems: 1. The generated flue gas has a large absorption of flue gas while cooling, and it will also block some flue gas, resulting in low flue gas throughput; 2. Polylactic acid material has thermoplasticity, which is prone to deformation when heated, causing the cooling section to collapse, thereby affecting cooling The supporting performance of the section on the cigarette; 3. The structure of the cigarette filter rod is complex, and the production cost is high; 4. The incense loading in the cooling section needs to be carried out separately after the preparation of the cigarette cooling section is completed, and the process is complicated and the cost is high.
为了解决以上问题，提出本发明。In order to solve the above problems, the present invention is proposed.
