 本发明的实施方式
为了更清楚的阐释本申请的整体构思，下面结合说明书附图以示例的方式进行详细说明。
在本申请中，应理解，诸如“包括”、“包含”或“具有”等术语旨在指示本说明书中所公开的特征、数字、步骤、行为、部件、部分或其组合的存在，并且不旨在排除一个或多个其他特征、数字、步骤、行为、部件、部分或其组合存在的可能性。
另外还需要说明的是，在不冲突的情况下，本申请中的实施例及实施例中的特征可以相互组合。下面将参考附图并结合实施例来详细说明本申请。
参考图1-图3，本申请的实施例提供一种加热可抽吸制品2，包括：沿加热可抽吸制品2长度方向依次排列的雾化基质段201、冷却段202和过滤段203；冷却段202用于冷却雾化基质段201受热所产生的烟雾，过滤段203用于过滤烟雾中的至少一种成分。
雾化基质段201内的材料在加热时通常挥发气溶胶。雾化基质段201内的材料可以是含非烟草的材料或含烟草的材料。雾化基质段201内的材料可以包括例如烟草本身、烟草衍生物、膨胀烟草、复原烟草、烟草提取物、均质化烟草或烟草替代物中的一种或多种。
当然，为将雾化基质段201、冷却段202和过滤段203结合成一个整体，通常会采用例如烟纸的材料(未示出)将它们包裹成一个长条棍状。
为使烟雾的温度下降到合适的温度，本申请作出两方面的探索。以下分别介绍两种降温手段。需要说明的是，这两种手段可以结合在一起使用。
参考图3，在第一种降温手段中，冷却段202包括涂布在其主体结构的内表面上的相变涂层2024，相变涂层2024包含相变材料，相变材料中的成分在45℃到150℃的温度范围内至少具有两个相变温度，相变温度为固体-固体相变温度或固体-液体相变温度。
固体材料在发生相变时，会吸收大量的热能。本申请的实施例采用的相变材料完成相变后可能呈固体态，仍保留在相变涂层2024内。相变材料完成相变后也可能呈液体态，通过控制液体的含量，可以使得这些液体以薄膜的形态吸附在冷却段202主体结构的内表面上。相变材料中的一些成分可能是在一个温度下发生相变，而另一些成分在另一个温度下发生相变。通过对这些不同相变材料的成分比例的控制，可以实现将烟雾的温度控制在一个较为小的温度区间内。这个较为小的温度区间是可控的，换言之是可定制的。如此，能够提升用户体验。
当然，相变材料也可以是单一成分。
相变材料存在的形式不限于相变涂层。例如冷却段的主体结构可以是多层的，相变材料设置在两层之间的夹缝里，等等。
可选地，相变材料中的成分在52℃到100℃的温度范围内至少具有两个相变温度。如此，可以使出加热可抽吸制品2的烟雾的温度更接近用户感到舒适的温度区间。
可选地，相变材料包括：聚乙二醇、巴西棕榈蜡、聚乙烯醇、聚乙烯、聚乳酸、葡苷聚糖中的至少两种成分。
可选地，相变涂层2024还包含辅助材料，辅助材料用于提升口味。
例如，辅助材料包括香精、多糖、植物粉末中的至少一种成分。
可选地，相变材料按重量份记为40份-80份，辅助材料按重量份记为0.5份-10份。辅助材料的比重过低则改善口味效果不明显，过高则影响降温效果。
可选地，相变涂层2024还包含导热材料。导热材料用于提升相变涂层2024整体的热导率。
例如，导热材料包括石墨。
可选地，相变材料按重量份记为40份-80份，导热材料按重量计为5份-10份。导热材料比重过低影响热传导效率，过高则影响降温效果。
可选地，相变涂层2024还包含增塑剂。从而使得相变涂层2024柔韧性增强，易于加工。
例如，增塑剂包括甘油、三醋酸甘油酯、羧甲基纤维(CMC)、海藻酸钠中的至少一种成分。
可选地，相变材料按重量份记为40份-80份，增塑剂按重量份计为5份-10份。增塑剂比重过低，则改善相变材料性质不明显，过高则影响降温效果。
可选地，相变涂层2024与冷却段202的质量比在5％-10％。相变涂层2024过重，则发生固体-液体相变时，液滴可能会从冷却段202的主体结构的内表面掉落。相变涂层2024过轻，则冷却效果不佳。
参考图1和图2，本申请实施例提供的第二种降温手段为：冷却段202上开设有多个通气孔2023。参考图4和图5，加热可抽吸制品2插入烟具主体1的容纳腔101时，通气孔2023应位于容纳腔101外，或者虽然位于容纳腔101内但仍与外界空气连通。由此，当用户吸食烟雾时，从通气孔2023内会有新鲜的空气流入冷却段202，对烟雾进行稀释的同时也会降低烟雾的温度。
具体地，通气孔2023可以是沿冷却段202的周向排成一排或多排。当然，通气孔2023的分布方式不限于此。
可选地，冷却段202的通风率在10％-70％。通风率过小，则降温效果不明显。通风率过大，则烟雾过于稀释，而影响口感。
可选地，参考图1，冷却段202的主体由一段中空纸筒形成。
可选地，冷却段202包括至少两段冷却子段，通气孔2023开设在其中一个冷却子段上。
参考图2，冷却段202由第一冷却子段2021和第二冷却子段2022连接而成。通气孔2023开设在第一冷却子段2021上。由于通气孔2023更靠近雾化基质段201，对烟雾的降温效果更明显。
采用多段冷却子段进行拼接，一方面便于加工，即可以分别加工具有通气孔2023的冷却子段和没有通气孔2023的冷却子段。另一方面，不同冷却子段的长度以及吸阻可以灵活调整，从而对烟雾温度的梯度进行更精确的调控，也就是对烟雾温度能够进行灵活精确的调控。
可选地，开设有通气孔的冷却子段的主体由中空纸筒形成。这是由于中空纸筒上开通气孔2023，可以很好地将外界空气进入冷却段202。
可选地，至少一段冷却子段的主体由中空醋纤棒形成。相对而言，中空醋纤棒的气阻更大，而且烟雾热量散发的更慢一些。
可选地，冷却段202由两段冷却子段拼接而成，两段冷却子段的长度均在7mm-22mm的范围内。该长度范围能够保障足够的冷却效果，又不会使加热可抽吸制品过长以至不方便使用。
参考图4和图5，本申请的实施例还提供一种加热不燃烧系统，包括烟具主体1和上述的加热可抽吸制品2，烟具主体1形成容纳腔101，容纳腔101具有开口，用于将加热可抽吸制品2的雾化基质段201插入容纳腔101，烟具主体1还包括设置在容纳腔101内表面上的加热元件102，用于对加热可抽吸制品2的雾化基质段201进行加热。
可选地，容纳腔101的深度与加热可抽吸制品2的长度之比在0.15-0.88的范围内。如此，便于对加热可抽吸制品2的雾化基质段201有效加热，又能留有适当空间对烟雾进行散热。
可选地，加热元件102位于容纳腔101的内部侧面上，发热元件102的发热区域的下边界高出雾化基质段201的下边界至少1mm。
换言之，发热元件102的发热区域与容纳腔101底部的距离比雾化基质段201与容纳腔101底部的距离至少大1mm。
如此，可防止烟雾从雾化基质段201底端流出。
可选地，加热元件102为红外加热元件。具体可以是涂布在容纳腔内部侧面上的红外涂层。红外涂层两端施加电压能够发出红外线，对雾化基质段201的加热更均匀。
以下为本申请提供的几个实验例，对以上两种降温手段的降温效果进行说明。
实验例一
如图4和图5所示，烟具主体1与加热可抽吸制品2配合使用。烟具主体1包括设有红外加热元件102的容纳腔101。加热可抽吸制品2包括：雾化基质段201、冷却段202和过滤段203。冷却段202长度为33mm，布置在紧邻雾化基质段201的下游。冷却段202为中空纸管。过滤段203为二醋酸纤维素丝束。过滤段203布置在冷却段202的下游，其吸阻为10Pa/mm。冷却段202周向布置有一排通气孔2023，形成通风率为30％的透气效果。容纳腔101深度与加热可抽吸制品2长度的比值控制在0.4-0.6，以此获得从过滤段203端部流出的烟雾温度能够控制在40℃-60℃之间。红外加热元件102围绕加热可抽吸制品2。红外加热元件102围成的加热腔室。插入容纳腔101的雾化基质段201应略超出红外加热元件102所围成的加热腔室的底端至少1mm，以防止烟雾从雾化基质段201底端逸出。

实验例六
与实验例一相比，为方便设备加工，冷却段202可由第一冷却子段2021和第二冷却子段2022组成，第二冷却子段2022位于第一冷却子段2021的下游。为避免紧邻雾化基质段201下游的第一冷却子段2021受热引起变形或产生异味，第一冷却子段2021为中空纸管，长度为13mm。第一冷却子段2021周向布置有一排通气孔2023，形成通风率为70％的透气效果。第二冷却子段2022为中空纸管，长度为20mm。
实验例七
如图3所示，与实验例一相比，冷却段202内设有多级相变材料，其添加形式为在冷却段202内壁涂覆有占冷却段202重量5％相变涂层2024。相变涂层2024内各成分按重量份如下：相变材料包含聚乙二醇30-50份、巴西棕榈蜡10-30份、葡苷聚糖粉2-5份；导热材料为石墨5-10份；增塑剂为甘油5-10份。其中聚乙二醇能在58℃下发生相变，由固态转化为液态吸热；巴西棕榈蜡能够在72℃下发生相变，由固态转化为液态吸热。
该相变涂层2024制备方法为：(1)称取聚乙二醇30-50份、巴西棕榈蜡8-20份放入容器中进行加热，加热温度设置为90℃左右；(2)待上述材料完全受热熔化变为液态后，将葡甘聚糖粉2-10份、石墨5-10份、甘油5-10份加入容器中，搅拌均匀；(3)将上述材料通过涂布工艺添加到冷却段202中。

采用上述实验例制成加热可抽吸制品2后，用烟具主体1内进行加热，并用测温仪器测试过滤段203出口处烟雾温度，具体数据如下。
 
Figure 457592dest_path_image001
从上述结果可以看出，当冷却段202全部使用中空纸管时，由于其内部空间较大，有利于降低烟气温度。进一步增加冷却段202通气孔2023的通风率，通过冷空气稀释，也可降低烟气温度，但是随着通风率增加，烟气浓度即烟雾量会降低。采用相变涂层2024涂覆冷却段202内表面后，在保证较大的烟雾浓度的同时，能够具有更好的降温效果。
以上仅为本申请的实施例而已，并不用于限制本申请。对于本领域技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原理之内所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
