技术领域
本公开涉及烟草制品领域，尤其涉及一种加热不燃烧烟支。
背景技术
加热不燃烧烟支是一种由电子设备加热而又不燃烧的烟草物质制成的卷烟。这种加热不燃烧烟支在抽烟过程中无明火，也没有烟灰，因此是一种环境友好型卷烟。这种卷烟在采用电子加热设备抽吸时，消费者不仅能够感受烟草香味，并且加热不燃烧烟支是在低温条件下被加热，可大幅度降低主流烟气中的焦油和有害物质的释放，与传统卷烟相比减少了常规卷烟在燃烧中高温热解所产生的有害物质，为消费者提供了一条有效的健康式抽烟方式。这种抽烟方式在国内外越来越流行，已拥有一定的消费群体，并且因此加热不燃烧烟支已成为烟草行业发展的主流方向。
然而，现有的加热不燃烧烟支通常存在烟雾量较小以及入口烟气温度较高等问题，对用户的使用体验造成较为明显的消极影响。
发明内容
本公开的目的包括，例如，提供一种加热不燃烧烟支，特别是一种颗粒型加热不燃烧烟支，以克服现有技术中的不足。
本公开实施例提供如下技术方案：
一种颗粒型加热不燃烧烟支，包括：芯部以及周向包覆所述芯部的筒形包裹件；
芯部包括沿其轴向方向依次设置的烟芯元件、气雾流通元件和过滤元件；
烟芯元件中的加热不燃烧烟草材料为颗粒状，气雾流通元件设有用于向所述过滤元件流通所述烟芯元件产生的烟气的一个或多个通道。
上述轴向方向意指平行于筒形包裹件的主体的延伸方向。更具体地，筒形包裹件包括第一端和第二端，并且该第一端为在用户抽吸烟支时远离用户的嘴部的一端，相反地，第二端为靠近用户的嘴部的一端。筒形包裹件的主体在第一端与第二端之间延伸。
上述轴向方向也意指与用户在抽吸加热不燃烧烟支时所述烟气的总体上的流动方向平行的方向。烟气从芯部的上游流动至芯部的下游。烟芯元件设置在芯部的上游(上游端，也即邻近筒形包裹件的第一端的端部)，过滤元件设置在芯部的下游(下游端，也即邻近筒形包裹件的第二端的端部)，并且气雾流通元件设置在烟芯元件与过滤元件之间，使得用户在抽吸加热不燃烧烟支时由烟芯元件产生的烟气能够经由气雾流通元件到达过滤元件。
另外，在一些实施方式中，过滤元件可以是单独于烟支设置的元件，即芯部不包括过滤元件。
颗粒型的加热不燃烧烟草材料加热后产生的烟气更足、香气更浓烈，吸烟者的抽吸感受更好。通过设置气雾流通元件，将加热芯材和过滤元件隔离开，可以有效避免热的烟气快速到达吸烟者唇部所引起的高温不适感，同时也避免了单纯的中空部所引起的塌陷。与单纯的过滤元件相比，设置气雾流通元件可以使得烟气流通更顺畅，在降温的同时减少过滤元件过长所造成的烟气和香味的损失。通道的孔径可以设计成小于加热不燃烧烟草材料的粒径，以避免加热不燃烧烟草材料进入通道，造成堵塞。
需要说明的是，加热不燃烧烟草材料是由烟草原料粉碎后经过加工得到再造加热不燃烧烟草原料，然后颗粒化得到的，并不是指常规的烟草原料。
可选地，所述颗粒状可以为圆球状和/或椭球状。
对加热不燃烧烟草材料的形状的进一步优选，有利于进一步优化产生烟气的量，进而提升抽吸感受。
颗粒状的加热不燃烧烟草材料可以直接装填至筒形包裹件中形成烟芯元件，也可以预先成型后装填至筒形包裹件中，成型的形状可选例如中空柱状或圆柱体蜂窝状等。
可选地，通道可以由气雾流通元件和筒形包裹件共同构成。
由气雾流通元件和筒形包裹件形成的通道不易被颗粒状的烟芯材料堵塞并且更易聚集烟气，其原因在于，当颗粒状的加热不燃烧烟草材料灌入筒形包裹件，由于颗粒为圆球或椭圆状，颗粒与筒形包裹件内壁接触并形成一定的空间，筒形包裹件内壁附近的颗粒密度要小于中心部位的密度，故在抽吸时，烟气量容易聚集到筒形包裹件内壁附近；将通道设置在筒形包裹件内壁附近更有利于烟气顺利的进入气雾流通元件。
可选地，气雾流通元件包括中心部及沿中心部的表面周向地间隔设置的多个凸起部。
相邻的凸起部与筒形包裹件、中心部一起形成烟气的通道，这样的设计使得通道的分布更加合理，进而使得烟气流通更加均匀。
另外地或可替代地，中心部沿轴向方向可以设置有通孔。
在中心部设置通孔，为烟气流通提供了额外的通道，烟气流通更加通畅。
可选地，通孔的孔径沿轴向方向保持一致或沿轴向逐渐变化。
孔径一致的通孔加工更方便，流通更均匀。孔径渐变的通孔可以使得烟气入口和烟气出口之间流速不同，形成气压差，能够对烟气起到一定的降温作用。
可选地，通孔的孔径可以沿轴向方向从烟芯元件朝向过滤元件的逐渐变小。
可选地，中心部可以包括圆筒部和底部，所述凸起部沿所述圆筒部的外侧周向设置，所述通孔开设在所述底部上。
将中心部设置成为圆筒状，一方面可以节约加工原料降低成本，另一方面可以减轻烟支重量，还可以使得烟气在通孔前后形成压力差，有助于烟气降温。
可选地，气雾流通元件的材质可以为能够耐受130-200℃的材料。
烟芯元件加热后会传导热量给气雾流通元件，采用耐高温材料是一方面为了避免气雾流通元件因受热而变形，保证烟支结构的稳定性，另一方面是为了避免气雾流通元件因受热产生异味，给吸烟者带来不适感和健康危害。气雾流通元件的材质仅需耐受烟气温度即可。气雾流通元件可以选用例如PP、PET，或者其他符合要求的工程塑 料，或者多种符合要求的高分子材料的混合物作为原料。
可选地，所述过滤元件为实心滤棒、中空滤棒或异形滤棒中的一种，所述过滤元件的材质为醋酸纤维或聚乳酸。
在一个可选的实施方式中，过滤元件可以采用常规的实心醋纤滤棒。采用中空滤棒或异形滤棒，相比实心滤棒而言，烟气流通效果更好，损失更小。
可选地，所述过滤元件为中空滤棒，所述中空滤棒的内径为1.6-6mm。
中空滤棒的内径尺寸可以选择成有利于保证烟气过滤、烟气流通量之间的平衡。
可选地，筒形包裹件为硬纸管。
采用硬纸管加工方便，加热不燃烧烟支结构的强度和稳定性能够得到保证，抽吸过程中不会发生塌陷。
可选地，所述硬纸管的厚度为0.25-1.2mm，所述硬纸管的外圆周长为16.9-25mm。
在其他的可选的实施方式中，硬纸管的厚度和周长可以根据实际需要进行调整。
可选地，所述颗粒型加热不燃烧烟支还包括端部中空部，所述端部中空部与所述过滤元件远离所述气雾流通元件的一端邻接。
设置端部中空部一方面可以方便加热不燃烧烟支在生产和装配时通过机械装置将各个部件放入筒形包裹件内，降低对生产的精度的要求；另一方面端部中空部作为抽吸者唇部和过滤元件的缓冲空间，避免抽吸者唇部直接接触过滤元件，进一步降低高温烟气所带给抽吸者的不适感。
可选地，颗粒型加热不燃烧烟支还包括封口部件，封口部件设置在烟芯元件的远离气雾流通元件的一端。
当采用直接装填方式将颗粒状的加热不燃烧烟草材料置入烟芯元件所对应的位置时，需要进行封装，用封口部件封闭颗粒型加热不燃烧烟支的头端。
可选地，烟芯元件的长度为13-15mm。
由于通常对烟芯元件进行加热的加热片的长度为12mm，因此加长烟芯元件的长度，使得使用时加热片与气雾流通元件之间存在1-3mm的间距，避免加热片对气雾流通元件进行直接加热，导致气雾流通元件变形及产生异味。
本公开实施例提供的上述颗粒型加热不燃烧烟支至少具有如下优点：
(1)使用颗粒型加热不燃烧烟草材料，烟雾量和香气更足，吸烟者的抽吸感受更好；
(2)气雾流通元件将烟芯元件和过滤元件隔开，采用多通道结构，一方面使得烟气流通更顺畅，另一方面能够避免筒形包裹件的塌陷，再一方面可以起到空气冷却作用，避免高温烟气烫嘴。
本公开实施例的目的还包括，例如，提供另一种加热不燃烧烟支，同样具有烟雾量大、入口烟气温度低等优点。
本公开实施例提供的另一种加热不燃烧烟支包括筒形包裹件、设于所述筒形包裹件内部并且依次排列的烟芯元件、气雾流通元件以及过滤元件。气雾流通元件中设有多个烟气通道。气雾流通元件与过滤元件间隔设置，例如，加热不燃烧烟支还包括设于气雾流通元件与过滤元件之间的第一中空部。
在本公开实施例中，烟芯元件、气雾流通元件以及过滤元件沿筒形包裹件的轴向方向顺序地设置在筒形包裹件围成腔室内，其中，烟芯元件设置在筒形包裹件的上游 (即，设置在筒形包裹件的远离用户抽吸烟支时的嘴部的一端)，过滤元件设置在筒形包裹件的下游(即，设置在筒形包裹件的靠近用户抽吸烟支时的嘴部的一端)，并且气雾流通元件设置在烟芯元件与过滤元件之间，并且其中，用户在抽吸加热不燃烧烟支时烟芯元件产生的烟气从上游流通至下游。
可选地，气雾流通元件包括中心部以及分布于所述中心部的表面并且间隔设置的多个凸起部，所述多个凸起部之间的间隔区域形成所述多个烟气通道。
可选地，中心部上设有一个或多个用于使烟气流通的通孔。
可选地，中心部上仅设一个通孔，所述通孔包括相互连接以形成贯通的通孔的第一孔与第二孔，所述第二孔的长度与孔径分别大于所述第一孔的长度与孔径。
可选地，第一孔邻近烟芯元件设置，所述第二孔邻近第一中空部设置。

抽吸时，使用加热片烟芯元件2，使得加热不燃烧烟草材料产生烟气，并且在吸烟者的抽吸力作用下，烟气流通经过气雾流通元件3，再经过过滤元件4到达吸烟者的口腔。
本公开实施例提供的加热不燃烧烟支的剖面呈矩形截面形状，该烟支的至少由芯材2、包括多个用于流通烟气的通道5的气雾流通元件3以及过滤元件4构成的芯部设置在由筒形包裹件1围成的腔室内。芯材2可以设置在腔室的远离用户抽吸烟支时的嘴部的一端，过滤元件可以设置在腔室的靠近用户抽吸烟支时的嘴部的另一端，并且气雾流通元件3可以设置在芯材2与过滤元件4之间。气雾流通元件3的一侧与芯材2连通，相反的另一侧与过滤元件4连通，使得用户在抽吸烟支时由芯材2产生的烟气能够通过气雾流通元件3到达过滤元件4，并进一步地经由过滤元件4到达用户的口腔。

参见图3，本公开实施例提供了另一种颗粒型加热不燃烧烟支，其整体上呈圆柱体状，并且总体上包括芯部以及周向地包覆芯部的筒形包裹件1。与图1和图2所示的实施例类似，本实施例中的芯部也包括沿其轴向依次设置的烟芯元件2、气雾流通元件3、过滤元件4，但不同之处在于，本实施例中的芯部还包括端部中空部6。特别地，本实施例中的烟芯元件2、气雾流通元件3和过滤元件4的设置与参照图1、2的描述基本上类似，在此不再赘述。
在本实施例中，端部中空部6可以与过滤元件4的远离气雾流通元件3的一端邻接。
在本实施例中，筒形包裹件1类似地可以为硬纸管，硬纸管的厚度例如为1mm，和/或硬纸管的外圆周长例如为20mm。加热不燃烧烟草材料可以为椭球状。烟芯元件2的长度可以为13mm。
此外，可替代地，如图4所示，气雾流通元件3可以包括中心部7及沿中心部的外表面周向地间隔设置的凸起部8，相邻的两个凸起部与中心部7、筒形包裹件1一起构成通道5。气雾流通元件3的中心部7可以为实心结构，当然，在其他实施例中，该中心部也可以为中空或部分中空的结构。在此替代性实施例中，气雾流通元件3可以由能够耐受110℃高温的工程塑料制得。此外，气雾流通元件3的长度可以为7mm。过滤元件4可以为中空醋纤滤棒，并且相应地，中空醋纤滤棒的内径可以为3mm，长度可以为20mm。端部中空部6的长度可以为2mm。
在其他的实施例中，气雾流通元件3、过滤元件4和端部中空部6的长度可以根据需要进行调整。
需要说明的是，凸起部8的形状并不局限于图4中所示出的形状，在其他实施例中，其形状也可以是圆弧形、圆形、三角形等，图中仅作示意说明。
另外地或可替代地，在其他实施例中，硬纸管的厚度还可以例如为1.2mm，硬纸管的外圆周长可以例如为25mm；加热不燃烧烟草材料的形状可以为椭球状，烟芯元件2的长度可以为15mm。
另外地或可替代地，在一些实施例中，如图5和图6所示，气雾流通元件3可以包括具有通孔型通道的中心部7及沿中心部的外表面周向地间隔设置的凸起部8，并且相邻的两个凸起部与中心部7、筒形包裹件1一起构成通道5。通孔或通孔型通道9沿腔室的轴向方向延伸贯穿中心部7，并且通孔9的孔径可以沿轴向方向保持一致，但不限于此，例如该孔径的大小还可以根据需求而沿轴向方向变化。过滤元件4可以为异形滤棒。气雾流通元件3可以由能够耐受例如150℃高温的材料制得。
在一些实施例中，为了保证颗粒状加热不燃烧烟草材料在烟芯元件2中的整体稳定性，还可以在烟芯元件2远离气雾流通元件3的一端设置封口部件21，如图5所示。
另外地或可替代地，在一些实施例中，硬纸管的厚度还可以为0.5mm，和/或硬纸管的外圆周长还可以为22mm。加热不燃烧烟草材料可以为圆球状和椭球状材料的混合物。烟芯元件2的长度可以为13mm。

另外地或可替代地，参见图8，气雾流通元件3包括中心部7和凸起部8。中心部7可以包括圆筒部11和底部12。凸起部8可以沿圆筒部11的外侧周向设置。通孔9可以开设在底部12上，和/或可以与圆筒部11同轴设置。
与现有的加热不燃烧烟具例如IQOS加热不燃烧烟具相比，本公开实施例提供的颗粒型加热不燃烧烟支烟雾量大、抽吸劲头足，平均每支抽吸口数为13-15口，高于IQOS加热不燃烧烟具的11-12口，此外烟草原味接近传统卷烟，陈皮特征香、酒香特征香和沉香特征香特征明显。
请参阅图9至图14B，本公开实施例还提供另一种加热不燃烧烟支，特别是颗粒型加热不燃烧烟支，其总体上包括筒形包裹件10、设于所述筒形包裹件10内部并且沿筒形包裹件的轴向方向依次排列的烟芯元件20、气雾流通元件30以及过滤元件50。上述轴向方向与筒形包裹件的主体的整体延伸方向一致。
在本实施例中，气雾流通元件30中可以设有多个烟气通道40，例如图12A所示。
气雾流通元件30还可以与过滤元件50间隔开设置，例如，加热不燃烧烟支还可以包括设于气雾流通元件30与过滤元件50之间的第一中空部60。
如图9至图11所示，在本公开的一些实施方式中，第一中空部60可以由筒形包裹件10的一部分围成。
本公开实施例提供的加热不燃烧烟支在使用时，采用加热不燃烧烟具插入烟芯元件20中对其进行加热，烟芯元件20受热后产生烟气，烟气穿过气雾流通元件30后进入第一中空部60，再进入过滤元件50中，之后从过滤元件50远离第一中空部60的一端进入用户口腔内。
本公开实施例中的气雾流通元件30的作用例如包括，但不限于此：

2、气雾流通元件30中设有多个烟气通道40，使烟芯元件20在加热过程中产生的烟气能够顺利通过并进入第一中空部60中；
3、气雾流通元件30能够对烟气进行节流，起到类似膨胀阀的作用，烟气从气雾流通元件30中流过后，气压降低，温度降低。
第一中空部60的作用可以例如包括对穿过气雾流通元件30的多个烟气通道40的烟气进行聚拢，提升入口烟雾量，同时对烟气起到进一步降温的作用。
气雾流通元件30的材料可以为能够耐受90-200℃高温的材料，例如工程塑料。
如图12A至图14B所示，气雾流通元件30包括中心部31以及分布于所述中心部31表面并且沿中心部的表面间隔设置的多个凸起部32。多个凸起部32之间的间隔区域形成多个烟气通道40。可以看出，气雾流通元件30的整体结构大体上呈齿轮状。
在一些实施例中，中心部31的直径可以沿着轴线方向保持均匀一致，或者也可以沿着轴线方向渐变，例如中心部的直径从朝向烟芯元件的一端到朝向第一中空部或过滤元件的一端逐渐变大或变小。
可选地，烟气通道40可以为弯曲的通道，例如螺旋形通道。弯曲的通道能够增加烟气在烟气通道40中的流通时间，从而增加烟气与气雾流通元件30接触的时间，更有利于烟气的降温。
可选地，中心部31与多个凸起部32为同种材质并且为一体结构。
可选地，中心部31上设有一个或多个沿上述轴向方向延伸贯穿中心部以用于使烟气流通的通孔33，通孔33能够类似地起到烟气通道40的作用，相当于增加了气雾流通元件30中烟气通道40的数量。
例如，参见图12A、图12B以及图12C，气雾流通元件30的中心部31上可以仅设一个通孔33，该通孔33包括第一孔331(参见图12A)与第二孔332(参见图12B)。第一孔331与第二孔332连通以共同地形成通孔33，如图12C所示。第二孔332的长度与孔径可以分别大于第一孔331的长度与孔径，但是在其他实施例中，第二孔332的长度也可以小于第一孔的长度，和/或，第二孔332的孔径也可以小于第一孔331的孔径。
可选地，所述第一孔331邻近所述烟芯元件20设置，所述第二孔332邻近所述第一中空部60设置。
可选地，第一孔331与第二孔332可以例如均为圆孔，但是其他几何形状也不受限。
可选地，中心部31的长度可以为5-7mm。
可选地，第一孔331的直径可以为0.1-0.5mm，和/或第一孔331的长度可以为0.5-2mm。
可选地，第二孔332的直径可以为3-5mm，和/或第二孔332的长度可以为3-5mm。
再例如，参见图13A、图13B以及图13C，气雾流通元件30的中心部31上也类似地仅设一个通孔33，但不同之处在于，例如，通孔33具有位于中心部31一端的小孔端333以及位于中心部31另一端的大孔端334。通孔33的孔径从小孔端333至大孔端334逐渐增大，如图13C所示。通孔33既能以小孔端333朝向烟芯元件20设置，也能以大孔端334朝向烟芯元件20设置。
可选地，通孔33以大孔端334邻近烟芯元件20设置，以小孔端333邻近第一中空部60设置。当烟气从大孔端334进从小孔端333出时，通孔33能够起到类似节流阀的作用，烟气从通孔33流出后，烟气的压力降低，温度降低，从而增强气雾流通元件30的降温效果。
可选地，中心部31与通孔33同轴心设置，通孔33的轴截面为等腰梯形。
可选地，小孔端333的直径为0.5-2mm，大孔端334的直径为3-6mm。
又例如，参见图14A与图14B，气雾流通元件30的中心部31上设有间隔设置的多个通孔33。
可选地，所述多个通孔33均平行于所述中心部31设置，并且所述通孔33的孔径沿轴向保持均匀一致，所述通孔33的直径为0.5-2mm。
可选地，中心部31可以呈圆柱状，和/或中心部31的直径可以为3-5mm。
可选地，凸起部32的高度可以为0.3-2mm，和/或每两个相邻的凸起部32之间的间隔区域的宽度可以为0.5-2mm。
可选地，筒形包裹件10可以为圆筒形。
可选地，筒形包裹件10可以为纸管，纸管的厚度可以为0.25-1.2mm，和/或纸管的外圆直径可以为5-8mm。
可选地，烟芯元件20中的烟草材料为颗粒型烟草材料。
可选地，颗粒型烟草材料呈圆球状、椭球状或者不规则形状。
可选地，颗粒型烟草材料的粒径大于烟气通道40的径向尺寸。
可选地，多个通孔33沿中心部31的轴线平行地设置，通孔33的孔径沿轴向保持均匀一致。
可选地，过滤元件50可以为醋酸纤维滤棒或聚乳酸材料滤棒。
可选地，过滤元件50可以呈实心柱状、中空柱状或者不规则形状。
可选地，第一中空部60的长度可以为10-20mm。
可选地，如图9与图11所示，过滤元件50的下游还可以设有第二中空部(其也可以被称为端部中空部)70，在本公开实施方式中，第二中空部70可以例如由筒形包裹件10围成。该第二中空部70的作用例如包括使烟气在入口前进一步降温。该第二中空部70的长度可以为2-3mm。
本领域技术人员能够理解的是，术语“上游”、“下游”可以指示用户在抽吸加热不燃烧烟支时烟气流动的方向，烟气从筒形包裹件的上游(远离用户嘴部的一端)向筒形包裹件的下游(靠近用户嘴部的一端)流动。
可选地，加热不燃烧烟支的整体长度可以为40-45mm，外圆直径可以为5-8mm。
可选地，烟芯元件20的长度可以为13-20mm，特别地为13-14mm。目前市面上出售的加热不燃烧烟具中的加热棒(或加热片)的长度通常为12mm，本公开实施例通过将烟芯元件20的长度设计为13-20mm，特别地为13-14mm，也即是说，烟芯元件20的长度比加热棒(或加热片)的长度长，特别地比加热棒(加热片)的长度长1-2mm，能够避免加热棒与气雾流通元件30直接接触从而造成气雾流通元件30的损坏。
可选地，气雾流通元件30的长度可以为5-7mm。
可选地，过滤元件50的长度可以为5-7mm。
可选地，如图9、图10、图11所示，加热不燃烧烟支还可以包括设于烟芯元件20远离气雾流通元件30的一端处的封口部件80。封口部件80的材料例如包括烟草薄片、非烟草薄片、锡箔、铝箔、纸等材料中的至少一种。
可选地，封口部件80通过胶粘剂黏合或热压黏合等方式与烟芯元件20连接在一起，从而实现对烟芯元件20封口处理。
目前市面上的加热不燃烧抽吸制品的烟芯段与加热器接触的一端均为裸露状态，具有裸露烟芯段的加热不燃烧抽吸制品产品存在以下几个问题：1.裸露烟芯段的加热不燃烧抽吸制品在开封后，其烟支容易回潮，抽吸时导致烟雾量较小，烟气发烫；2.裸露烟芯段的加热不燃烧抽吸制品在烟支卷接包装的过程中容易掉落烟芯材料，会对产品质量带来参差不齐的影响；3.裸露烟芯段的加热不燃烧抽吸制品在放入加热器进行抽吸的过程中(插入加热器中或从加热器中拔出)，烟芯材料会脱落在加热器中，造成对加热器的污染，且必须要频繁的清理加热器，给消费者带来诸多的不良体验。
本公开实施例通过采用封口部件80对烟芯元件20进行封口处理，能够避免出现烟芯材料回潮、烟芯材料易掉落等问题，并且封口后的加热不燃烧烟支不会改变其本身具有的各种性能。
综上所述，本公开实施例提供的加热不燃烧烟支在烟芯元件20与过滤元件50之间设置气雾流通元件30，气雾流通元件30能够阻挡烟芯元件20中的烟草材料移动，防止烟草材料进入过滤元件50中；此外，气雾流通元件30中设有多个烟气通道40，使烟芯元件20受热时产生的烟气能够顺利通过气雾流通元件30并进入过滤元件50中，另外，气雾流通元件30还能够对烟气起到降温效果；本公开实施例提供的加热不燃烧烟支还可以在气雾流通元件30与过滤元件50之间设置第一中空部60，第一中空部60的作用例如包括对穿过气雾流通元件30后的烟气进行聚拢，提升入口烟雾量，同时对烟气起到进一步降温的作用。
另外地，本公开实施例提供的加热不燃烧烟支还可以在过滤元件50的下游设置第二中空部70，该第二中空部70的作用例如包括使烟气在入口前进一步降温。
另外地，本公开实施例提供的加热不燃烧烟支还可以采用封口部件80对烟芯元件20进行封口处理，以例如避免出现烟芯材料回潮、烟芯材料易掉落等问题。
下面将结合具体实施例对本公开提供的加热不燃烧烟支进行详细描述，但是本领域技术人员将会理解，下列实施例仅用于说明本公开，而不应视为限制本公开的范围。实施例中未注明具体条件者，按照常规条件或制造商建议的条件进行。
此外，要强调的是，下述不同的实施例并非严格的独立不相关的关系，事实上，下述实施例中的部件的特征在不影响实施的情况下可以相互组合或拆分从而形成另外的实施例。
