技术领域
本公开涉及加热不燃烧卷烟领域，尤其涉及一种加热不燃烧烟支及其制备方法和加热不燃烧系统。
背景技术
加热不燃烧卷烟相对于普通卷烟，抽吸时温度较低，因此对消费者身体的伤害相对较小，受到抽烟爱好者的普遍欢迎。目前市面上的加热不燃烧卷烟多以菲莫的IQOS烟弹和英美烟草的GLO烟烟支为主，烟支结构以使用四元结构为主。
此类烟支结构对气溶胶吸附效果较强，抽吸时烟气量远不如传统卷烟，且加工过程较为复杂，成本较高。
此外，加热不燃烧烟支的烟芯材料无外乎片状、丝状、颗粒状等形态，对于片状、丝状烟芯材料，为保证被加热器充分加热，不管是有序排列还是无序排列，都需要排列得很紧密，增加接触面，以利热量传导，这样就不能为烟气的聚集提供空间，消费者吸食到口中的烟气量少、烟气浓度低。颗粒状烟芯材料虽然在颗粒与颗粒之间形成空隙，但存在表面的烟香物质很容易受热挥发，内部的却因为外表面的裹缚而难以溢出的问题。

连接词“由……组成”排除任何未指出的要素、步骤或组分。如果用于权利要求中，此短语将使权利要求为封闭式，使其不包含除那些描述的材料以外的材料，但与其相关的常规杂质除外。当短语“由……组成”出现在权利要求主体的子句中而不是紧接在主题之后时，其仅限定在该子句中描述的要素；其它要素并不被排除在作为整体的所述权利要求之外。
