近年来，随着《烟草控制框架公约》的颁布与实施，各国政府的烟草管控措施日趋严格，对烟草的监管立法也愈加严格，控烟和反烟的呼声越来越强烈，国内外市场竞争压力持续增大。同时，随着人们生活水平的不断提高，人们更加注重自己的身心健康和环境保护，对烟草有了新的认识。
诸如上述原因使传统卷烟的发展受到越来越多的制约，据2011年统计数据显示，在世界范围内卷烟产销量有所下降的同时，其他类型烟草制品呈现快速增长趋势，世界烟草市场产品结构不断发生深刻变化，积极发展全系列烟草制品逐渐成为各个跨国烟草公司的战略取向。目前，市场上已出现了三种主要的新型烟草制品类型：加热不燃烧型烟草制品、电子烟和无烟气烟草制品。其中，加热不燃烧烟草制品是一种靠加热不同形式的烟草材料产生释烟效果的新型烟草制品，始于20世纪80年代，是新型烟草制品的重要品类之一。
加热不燃烧烟草制品一般是通过“加热不燃烧”的方式将烟草香味传递给消费者，其外观与消费方式上也与传统卷烟相似，在一定程度上适应和满足了消费者的生理需要和心理需求。这种“加热不燃烧”的方式，使烟草只在较低的温度下(一般低于500℃)被加热，避免了烟草高温燃烧导致的焦油和大量有害化合物生成，而且由于基本没有侧流烟气，不会产生二手烟气，不会对公共环境产生影响。近年来众多烟草制造企业、研究机构都看到了加热不燃烧烟草制品的巨大潜力，重金投入这一领域，并收获颇丰。其中，电加热不燃烧烟草制品由于具有加热温度可控、加热方式灵活、使用方便时尚等优点，具有更高的关注度，是当前国内外加热不燃烧烟草制品的重要发展方向。
加热不燃烧烟草制品的技术核心主要包括热源和释烟材料两个方面。热源类型分为电加热、碳加热以及化学反应加热三种类型，其中电加热和碳加热两种热源已经应用于产品，如菲莫烟草公司的“iQOS”和雷诺烟草公司的“Revo”。释烟材料是影响加热不燃烧烟草制品抽吸体验的关键因素，目前所开发的释烟材料主要包括烟丝、烟末、烟草薄片等。这些材料在不同的加热环境下能够释放具有烟草特征香气的烟气，但普遍存在受热不均匀、易碳化、操作不便等缺陷。其中烟丝和烟末由于难以添加雾化剂，存在烟雾量小、发烟不均匀、易焦化等问题；而“iQOS”所用的烟草薄片虽然解决了发烟量问题，但制造工艺复杂、设备成本昂贵，可调控性不强，且烟气中存在较重的烧纸味，影响口感。同时，现有产品在使用后，释烟材 料由于焦化、碳化、粘结等原因会残留于电加热组件上，需要配套专门的工具对加热组件进行清洁；再者，现有薄片型加热不燃烧卷烟在抽吸完毕后，直接拔出，烟丝会掉落在烟具加热室内，因此需要烟支辅助拔出部件。
针对上述以烟丝、烟末、烟草薄片作为释烟材料的烟草制品所存在的问题，专利CN108065456A、CN108143003A、CN 108143005A、CN 108185524A等提出了一种以烟草颗粒为释烟材料的加热不燃烧烟草制品，但其皆存在以下问题：烟支结构设计复杂；烟草颗粒灌封效果差、效率低；所选择的烟草颗粒承载封堵材料在受热条件下收缩，导致颗粒掉落。因此，一种烟气释放充足均匀、烟草颗粒不掉落、烟支可直接拔出的新型加热不燃烧烟草制品亟待开发。

具体实施方式
下面对本发明的实施例作详细说明，本实施例在以本发明技术方案为前提下进行实施，给出了详细的实施方式和具体的操作过程，但本发明的保护范围不限于下述的实施例。
如图1所示，一种烟草颗粒型加热不燃烧烟草制品，包括烟草颗粒段1和滤嘴段。烟草颗粒段1是在纸空管11的前端和尾端分别固定有前端封堵结构13和尾端封堵结构14，在前端封堵结构13和尾端封堵结构14之间填充有烟草颗粒12；尾端封堵结构14与滤嘴段相临近。滤嘴段包括依次相连的第一降温段2、第二降温段3和过滤段4；第一降温段2靠近烟草颗粒段1、过滤段4位于唇端。烟草颗粒段1的纸空管与第一降温段2外包裹有不透气成型纸5，形成纸空管/第一降温段二元复合棒；第二降温段3和过滤段4外包裹有高透气成型纸6，形成第二降温段/过滤段二元复合棒；纸空管/第一降温段二元复合棒与所述第二降温段/过滤段二元复合棒通过商标纸7搓接。商标纸包裹所述第二降温段/过滤段二元复合棒的全部、包裹第一降温段的5cm长度。
前端封堵结构13和尾端封堵结构14皆呈瓶盖状，以前端封堵结构13为例，如图2所示，其包括一圆片状的盖部131和具有凸起褶皱和凹陷牙口的裙部132，盖部设置有若干通孔。前端封堵结构13以盖部临近纸空管内的烟草颗粒，裙部粘接固定在纸空管11的内壁上，且裙部顶端与纸空管11的前端口平齐；尾端封堵结构14以裙部临近纸空管内的烟草颗粒，塞入在纸空管11内，且盖部底端与纸空管11的尾端口平齐。尾端封堵结构和前端封堵结构的裙部采用具有凸起褶皱和凹陷牙口的啤酒瓶盖式结构，可以增加与纸空管内壁的接触面积，避免滑动；且可以保证前端封堵结构在纸空管内壁的粘接强度。尾端封堵结构的盖部用以防止烟草颗粒掉落至空腔嘴棒中，前端封堵结构的盖部用以防止烟草颗粒从纸空管中掉落至烟支外。
本实施例所用烟草颗粒材料参见专利CN108143003A实施例1。
具体实施时，前端封堵结构13所用材料为铝箔衬纸(本实施例中，其克重为45g/m 2)，尾端封堵结构14所用材料为铝箔(本实施例中，其厚度为40μm)。烟支抽吸时，冷空气从前端封堵材料铝箔衬纸进入，与烟草颗粒受热释放的烟气混在一起形成热气流，该热气流流经尾端封端材料铝箔后进入滤嘴段。因此，尾端封端材料采用铝箔，耐热性好、受热不会释放有害成分，并有一定的降温功效。前端封堵材料采用铝箔衬纸，是由于需通过粘合剂将铝箔衬纸的衬纸面与纸空管内壁粘合在一起，其粘合强度远远好于铝箔面与纸空管内壁之间的粘合强度。另外，采用铝箔衬纸作为前端封堵材料也要好于直接采用纸张作为前端封堵材料， 原因是铝箔衬纸中因为金属铝箔的存在，其塑性和防渗透性均好于纸张。
具体实施时，前端封堵结构13和尾端封堵结构14的盖部通孔直径在0.05-0.4mm、孔边距在1-2mm；前端封堵结构13的裙部高度和尾端封堵结构14的裙部高度均为1.0-2.5mm。若通孔直径低于0.05mm，会导致吸阻过大，烟气量小，抽吸体验差；若通孔直径高于0.4mm，会导致烟草颗粒掉落。若前端封堵结构的裙部高度低于1.0mm，其与纸空管粘结强度不够，存在封堵结构因粘结不牢固而掉落的风险；若后端封堵结构的裙部高度低于1.0mm，其与纸空管接触面积低，存在封堵结构滑动的风险。若前端封堵结构裙部高度大于2.5mm，会降低烟草颗粒的有效填充量，还会给制备带来难度，降低生产效率；若后端封堵结构裙部高度大于2.5mm，不仅浪费材料，还不利于高速生产。本实施例中：前端封堵结构13的盖部通孔直径为0.2mm、孔边距为1mm，裙部高度均为2mm；尾端封堵结构的盖部通孔直径0.1mm、孔边距为1mm，裙部高度均为2mm。
具体实施时，纸空管11的内层粘附有一层铝箔。该铝箔层具有优良的阻隔功能，可有效防止储存或抽吸过程中烟草颗粒中化学物质的渗出。
具体实施时，纸空管11的外径为22.0-24.0mm、壁厚为0.2-0.4mm、长度为12-20mm。本实施例中，纸空管的外径为22.5mm、壁厚为0.2mm、长度为15mm。
具体实施时，第一降温段2为含有相变材料的异型醋纤嘴棒，其异型结构位于嘴棒外围和/或嘴棒内部。如图3所示，位于嘴棒外围的异形结构是在嘴棒圆柱面沿周向均匀分布有3-5个“V”形沟槽2a，沟槽体积占整个嘴棒体积的10-20％之间；位于嘴棒内部的异形结构是在嘴棒中轴设置有一个沿嘴棒轴向贯通的空腔，空腔截面呈圆形、三角形(如图4所示，图中2b为截面呈三角形的空腔)、四边形、五角星形、六角星形或七角星形，空腔体积占整个嘴棒体积的7-18％。相变材料为分子量在4000-40000之间的聚乙二醇，是在异型醋纤嘴棒加工时均匀喷洒在二醋酸纤维素上；相变材料的质量占异型醋纤嘴棒总质量的10-30％。本实施例中，用作第一降温段2的异型醋纤嘴棒的异形结构是在嘴棒圆柱面沿周向均匀分布有5个“V”形沟槽2a，沟槽体积占整个嘴棒体积的15％，所用相变材料为分子量6000的聚乙二醇，其质量占异型醋纤嘴棒总质量的20％。
具体实施时，用作第二降温段3的聚乳酸嘴棒是在第二降温段的成形纸31成形纸内包裹有聚乳酸降温材料32；聚乳酸降温材料为丝束状聚乳酸或面条状聚乳酸；丝束状聚乳酸的直径在50-300μm；面条状聚乳酸的宽度为0.5-2.0mm、厚度为25-50μm；当采用丝束状聚乳酸时，聚乳酸嘴棒的吸阻在300-1000pa/100mm；当采用面条状聚乳酸时，聚乳酸嘴棒的吸阻在100-400pa/100mm。本实施例采用直径在100μm的丝束状聚乳酸，嘴棒吸阻为500pa/100mm。
相变材料具有吸收存储热量的特性，通过在异型醋纤嘴棒中加入聚乙二醇相变材料，可 以降低烟气的温度。但含相变材料的异型嘴棒由于纵向气流通道较大，难以将烟气温度降低至空腔能接受的温度，因此采用了聚乳酸降温棒与其配合共同降温。聚乳酸嘴棒中的聚乳酸呈丝束状或面条状，具有较大比表面积，与烟气接触更为充分，因此降温效果更好。但如果全部用聚乳酸嘴棒，会导致烟气被截留过大，导致烟气量偏低，因此，选用两种降温棒配合使用。对于第一降温段：沟槽或空腔体积过低，会对烟气有较大截留；沟槽或空腔体积过高，降温效果大打折扣。对于第二降温段：若采用丝束状聚乳酸，吸阻超过1000pa/100mm时，对烟气截留严重，吸阻低于300pa/100mm时，材料有效地降温面积偏低，降温效果有限；若采用面条状聚乳酸，吸阻低于100pa/100mm时，降温效果有限，吸阻高于400pa/100mm时，同样会对烟气有较大截留。
具体实施时，用作过滤段的醋纤嘴棒是由过滤段的成形纸41包裹醋酸纤维素42而成；当过滤段采用异型醋纤嘴棒时，异形结构是在嘴棒中轴设置的一个沿嘴棒轴向贯通的空腔，空腔的体积占整个异型醋纤嘴棒的体积比不高于10％；当过滤段采用实心醋纤嘴棒时，吸阻不高于1000pa/100mm。本实施例的过滤段采用实心醋纤嘴棒，其吸阻为1000pa/100mm
具体实施时：第一降温段2的长度为7-12mm、直径为22.0-24.0mm；第二降温段3的长度为15-18mm、直径为22.0-24.0mm；过滤段4的长度为7-10mm、直径为22.0-24.0mm；烟草颗粒段1、第一降温段2、第二降温段3及过滤段4的直径相同。本实施例中，各段直径皆为22.5mm，第一降温段2、第二降温段3及过滤段4的长度分别为10mm、15mm、10mm。
本实施例还提供了上述烟草颗粒型加热不燃烧烟草制品的制作方法，包含以下步骤：
1)基棒制备：
利用螺旋纸管机将纸和铝箔纸螺旋粘接形成纸空管；
将相变材料聚乙二醇通过高压雾化的工艺均匀喷洒在醋酸纤维素中，然后利用嘴棒成型机制成作为第一降温段的异型醋纤嘴棒；
利用嘴棒成型机将聚乳酸降温材料包裹在成型纸内，形成用作第二降温段的聚乳酸嘴棒；
利用嘴棒成型机将醋酸纤维素包裹在成型纸内，形成用作过滤段的实心或异型醋纤嘴棒；
2)复合嘴棒制备：
利用二元复合嘴棒成型机，将纸空管和第一降温段通过不透气成型纸包裹连接、将第二降温段和过滤段通过高透气成型纸包裹连接，分别获得纸空管/第一降温段二元复合棒、第二降温段/过滤段二元复合棒；
3)空管烟支制备：利用卷烟搓接机，将纸空管/第一降温段二元复合棒与第二降温段/过滤段二元复合棒通过商标纸搓接，形成空管烟支；
4)烟草颗粒的灌封：利用转换鼓轮将空管烟支转移到纸空管垂直向上的状态；将尾端封 堵结构塞入纸空管内；再利用量杯法将烟草颗粒定量灌装进纸空管内，并在前端预留出前端封堵结构所需的高度；然后利用移印涂胶技术将未灌装烟草颗粒的纸空管内壁涂胶后，将前端封堵结构塞入并粘牢；最后经干燥，即完成烟草颗粒型加热不燃烧烟草制品的制作。
将本实施例所提供的烟草颗粒型加热不燃烧烟支产品与某市售薄片型烟支产品进行对比，在相同烟具抽吸下，抽吸模式是抽吸持续时间2s、抽吸间隔是30s，连续抽吸8口，测试3次，取平均值。烟气温度变化如表1所示，可以看出，本实施例所提供的烟支产品烟气逐口温度和总平均温度均低于某市售产品，说明本实施例的降温组合具有较高的烟气降温效果。另外，本实施例的滤嘴对烟气总截留量为25.3％，而市售产品对烟气总截留量为26.9％，本实施例烟气截留量略低于某市售产品。综合来看，在基本不增加烟气总截留量的前提下，本实施例的烟支产品具有更优良的烟气降温效果。

    1)基棒制备：
    利用螺旋纸管机将纸制成纸空管，或利用螺旋纸管机将纸和铝箔纸螺旋粘接形成纸空管；
    将相变材料聚乙二醇通过高压雾化的工艺均匀喷洒在醋酸纤维素中，然后利用嘴棒成型 机制成作为第一降温段的异型醋纤嘴棒；
    利用嘴棒成型机将聚乳酸降温材料包裹在成型纸内，形成用作第二降温段的聚乳酸嘴棒；
    利用嘴棒成型机将醋酸纤维素包裹在成型纸内，形成用作过滤段的实心或异型醋纤嘴棒；
    2)复合嘴棒制备：
    利用二元复合嘴棒成型机，将纸空管和第一降温段通过不透气成型纸包裹连接、将第二降温段和过滤段通过高透气成型纸包裹连接，分别获得纸空管/第一降温段二元复合棒、第二降温段/过滤段二元复合棒；
    3)空管烟支制备：利用卷烟搓接机，将纸空管/第一降温段二元复合棒与第二降温段/过滤段二元复合棒通过商标纸搓接，形成空管烟支；
    4)烟草颗粒的灌封：利用转换鼓轮将空管烟支转移到纸空管垂直向上的状态；将尾端封堵结构塞入纸空管内；再利用量杯法将烟草颗粒定量灌装进纸空管内，并在前端预留出前端封堵结构所需的高度；然后利用移印涂胶技术将未灌装烟草颗粒的纸空管内壁涂胶后，将前端封堵结构塞入并粘牢；最后经干燥，即完成烟草颗粒型加热不燃烧烟草制品的制作。
