本申请要求于2017年12月07日提交中国专利局的申请号为201711284850.9、名称为“一种加热不燃烧卷烟滤嘴和加热不燃烧卷烟”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本申请涉及卷烟加工制造，具体而言，涉及一种加热不燃烧卷烟滤嘴、加热不燃烧卷烟及其使用方法。
背景技术
随着各国政府控烟力度的不断加强，以及人们越来越重视健康，烟草行业依赖传统的纸质卷烟获取利润增长的空间也在不断缩小，因此积极研发一种降低烟草有害成分释放量的新型烟草制品是一个必要的选择。
加热不燃烧卷烟利用特殊热源对烟丝进行加热(300℃左右)，烟丝只加热不燃烧，烟丝温度远远低于传统卷烟，烟气有害化学成分和生物毒性大幅降低，可以减少烟草高温燃烧裂解产生的有害成分；同时，与传统卷烟的阴燃不同，它在抽吸间歇时烟丝处于非加热状态，因此侧流烟气和环境烟气也大幅降低。
鉴于加热不燃烧型卷烟的独特优势，人们对其的研究越来越深入,然而市场上关于烟支结构设计方面的研究较少，现有的加热不燃烧卷烟抽吸过程中仍存在沿其通过量较低，产生烟气浓度大等问题。

参阅图1至图4，本申请提供了一种加热不燃烧卷烟滤嘴10，包括相连的第一部分和第二部分，第一部分可以为过滤棒100，第二部分可以包括至少一个降温部200和至少一个中空部300，降温部200可以包括至少一个贯穿的空腔通道210，中空部300的中部为贯穿的空腔结构，空腔结构与空腔通道210连通。
请一并参阅图1至图4，本申请还提供了一种加热不燃烧卷烟1，包括加热不燃烧卷烟滤嘴10和烟草棒20，加热不燃烧卷烟滤嘴10为上述的加热不燃烧卷烟滤嘴10；烟草棒20与加热不燃烧卷烟滤嘴10的第二部分相邻，加热不燃烧卷烟滤嘴10和烟草棒20外部包裹成形纸。
本申请提供的加热不燃烧卷烟滤嘴包括用于对烟气中焦油、尼古丁等物质进行过滤的过滤棒100、用于对流经的高温烟气进行降温处理的降温部200和用于对流经的烟气进行聚拢储存的中空部300，抽吸时，在烟草棒内插入加热器，烟草棒通过对应的加热器加热后，用户对加热不燃烧卷烟滤嘴的过滤棒进行抽吸，烟气在抽吸作用下通过第二部分的中空部300、降温部200以及第一部分的过滤棒100，最后到达过滤棒100的出烟一端。其中，中空部300的空腔结构为一个较大的容纳腔，能够对烟气进行聚拢和储存，从而有效提高了烟气的通过量和烟气浓度；降温部200的空腔通道210则对流经的烟气进行降温处理，降低烟气温度，减少高温烟气温度过高与其他部件发生反应生产不良气体，影响用户抽吸感受情况的发生，从而提升卷烟的抽吸品质等；此外，降温部200在实现对烟气降温的基础上，空腔通道210的设置还能够减少降温部200对烟气流通造成的阻碍，提高烟气的流通量，从而保证用户抽吸烟气量的饱满度。
其中，加热不燃烧卷烟滤嘴10的过滤棒100、降温部200、中空部300与烟草棒20的外形可以为一致的圆柱状，成形纸30包裹在外部时，外形一致且包裹紧密度较好。
优选地，过滤棒100可以为醋酸纤维素过滤棒。
醋酸纤维素是指在醋酸作为溶剂，醋酐作为乙酰化剂，在催化剂作用下进行酯化，而 得到的一种热塑性树脂；醋酸纤维素是一种纤维素有机酸酯。，醋酸纤维素作为多孔膜材料，具有选择性高、透水量大、环保无毒、加工简单等特点，该材料制成的过滤棒100对用户不良影响较小，且能够有效过滤烟气中的焦油、尼古丁等物质，过滤效果好，进一步提高加热不燃烧卷烟1的使用性。
此外，过滤棒100还可以为其它复合滤棒，如活性炭与醋酸纤维素的复合滤棒等。
优选地，如图5所示，降温部200可以包括多个贯穿的空腔通道210，可列举为3个、4个、6个或7个等。更优地，多个贯穿的空腔通道210相互平行设置，且均匀地分布在降温部200内。
上述空腔通道210的截面优选为圆形，其直径优选为0.2～7mm如0.2mm、0.7mm、1.2mm、1.8mm、2.5mm、3mm、4mm、5mm、6mm或7mm等。当然空腔通道210的截面还可以为方形或其他形状等。
需要理解的是，降温部200采用了多个贯穿的空腔通道210，一方面，烟气通过降温部200时，能够与多个空腔通道210的侧壁接触散热，从而加大了与降温部200的接触面积，提高降低烟气温度的效果；另一方面，多个贯穿的空腔通道210大大提高了烟气的通过量，保证了烟雾量的饱满度。
具体的，降温部200的多个空腔通道210之间可以相互平行设置，且均匀分布于降温部200内部。降温部200内部的多个空腔通道210相互平行设置，烟气通过降温部200时流向一致，在实现对烟气降温的基础上，能够有效提高烟气流经降温部200时的气流稳定性，相应提高烟气的流通量，提高烟气饱满度。
本实施例中，中空部300空腔结构的轴线可以与降温部200空腔通道210的轴线共线或相互平行设置。烟气流经空腔结构与空腔通道210时，两者的轴线共线或相互平行设置，烟气流动方向不变，能够进一步提高烟气流经第二部分时的稳定性，进一步提高烟气的流通量及其饱满度。
需要说明的是，降温部200包括一个贯穿的空腔通道210时，优选地该空腔通道210位于所述降温部正中间，与降温部200共轴线设置，且该空腔通道210的直径为4～7.8mm如4mm、5mm、6mm、7mm或7.8mm等。
优选地，降温部200和中空部300的长度均可以为5～30mm如5mm、10mm、15mm、20mm、25mm或30mm等。
优选地，降温部200和中空部300均为圆柱形状，降温部200的直径为5～8mm如5mm、6mm、7mm或8mm等。
优选地，中空部300的直径可以为5～8mm如5mm、6mm、7mm或8mm等。
中空部空腔结构的直径可以为0.2～7mm，优选地，中空部300的空腔结构的直径可以 为2～5mm如2mm、3mm、4mm或5mm等。
优选地，中空部300与降温部200可以为材质相同的一体结构；其中，中空部300空腔结构的横截面积可以大于或等于空腔通道210的横截面积，也可以小于空腔通道210的横截面积。中空部300与降温部200为材质相同的一体结构，一方面，可以提高生产第二部分时的便捷度，降低生产成本；另一方面，还能够提高中空部300与降温部200连接的牢固度，且提高第二部分的整体性，相应提高成形纸包裹加热不燃烧卷烟滤嘴10及烟草棒20时的便捷性及牢固度。
这里需要说明的是，上述“中空部300空腔结构的横截面积”是指中空部300内一个、两个或多个空腔结构时，能够供烟气流通的所有空腔结构的总的横截面积；类似的，上述“空腔通道210的横截面积”是指降温部200内一个、两个或多个空腔通道210时，能够供烟气流通的所有空腔通道210的总的横截面积。
具体的，中空部300空腔结构的直径可以大于降温部200空腔通道210的直径，且中空部300空腔结构的横截面积等于降温部200空腔通道210的横截面积。这里是一种具体情况，该情况时，单个空腔结构的直径大于单个空腔通道210的直径，且中空部内空腔结构的总的横截面积等于降温部内空腔通道的总的横截面积，相应可知，降温部200内空腔通道210的个数要多于中空部300内空腔结构的个数。
此外，中空部300与降温部200还可以为材质不同的结构，其中，降温部200可采用聚乳酸材质或纸质材质，中空部300可采用醋酸纤维素材质。
需要说明的是，降温部200可以采用聚乳酸高分子材料，烟气通过时，不会由于烟气温度过高而引起的其他异味或造成烟支塌陷，可以有效提高用户抽吸舒适度。
优选地，烟草棒20为沿卷烟径向方向的若干规则且有序排列的烟丝条挤压靠拢在一起形成。
需要说明的是，烟草棒20采用的烟叶可为造纸法再造烟叶、干法再造烟叶、稠浆法再造烟叶、辊压法再造烟叶等人为加工的再造烟叶。
需要说明的是，上述将烟丝条有序排列使得烟丝条之间也形成了有序排列的空隙，较无序排列烟丝条大大提高了孔隙率，保证了卷烟内部良好的通气性和气流一致性；有序排列的烟丝条及其形成的有序排列的空隙，为烟气的流通提供了近似直线的气流通道，减少了抽吸的阻力及烟丝对烟气吸附性能，提高了烟气的通过效率，从而提高烟气的通过量并保证用户抽吸烟气的饱满度。

这里需要说明的是，文中将卷烟中过滤棒100端的方向定义为上游方向，相对的，卷烟中烟草棒20端的方向定义为下游方向。
上述加热不燃烧卷烟1用于抽吸时，将烟草棒20内插入相应的加热器，进行加热，待加热完成后，在醋酸纤维素过滤棒100处进行吸食，烟气通过其中一个中空部300内，将烟气聚拢后通过降温部200，再通过另一个中空部300，沿其流经第二部分的过程中，不仅降低了烟气温度，提高了烟气浓度，而且在烟支卷接复合时，减少了一次复合，提高生产效率，降低了烟支的成本。
