Description

一种不使用多通孔固件段的颗粒型气溶胶生成制品 技术领域
本发明属于气溶胶生成制品领域，尤其属于使用气溶胶源材料颗粒的气溶胶生成制品技术领域。
背景技术
颗粒型气溶胶生成制品是近年来新型的一种加热不燃烧型(Heat-Not-Burn，缩写为HNB)气溶胶生成制品，其以气溶胶源材料颗粒代替气溶胶源材料薄片作为气溶胶发生材料，气溶胶源材料颗粒比气溶胶源材料薄片受热更均匀，且气溶胶沿颗粒间间隙扩散也比沿薄片类材料间隙扩散更顺畅，因此深受消费者喜爱。
颗粒型气溶胶生成制品是市面上的已知产品，参考附图1说明其结构：其主体结构为一个一体化外套筒2，其远唇端被封口膜1所密封，然后向其中填充气溶胶源材料颗粒9形成颗粒段，并在颗粒段下游设置带有多通孔固件段(俗称“齿轮件”)20、然后留出一个空腔段10用于汇总和容纳气溶胶(有时候该空腔段10侧壁还设有空气进入孔以冷却该气溶胶，或者有时候该空腔段内填充有冷却材料或增香材料来冷却或增香)，空腔段10下游是过滤段4，兼作为烟嘴使用，供用户叼在口中。该烟支在使用时将远唇端插入加热器具中，加热器具具有中心加热元件，可刺破封口膜1插入到颗粒段内部对颗粒加热使其释放气态香味成分，气态香味成分在空腔段10中遇冷空气冷凝成肉眼可见的气溶胶，然后该气溶胶经过滤段过滤后进入用户口中。
其中空腔段10对于气溶胶形成是至关重要的，根据气溶胶科学理论，受热释放的气态香味成分需要遇冷才能冷凝成固体微粒或液体微粒，且该固体微粒或液体微粒需要悬浮在空气中才能形成肉眼可见的气溶胶(俗称“烟”或者“雾”或者笼统称为“烟雾”)，因此，在现有的颗粒型气溶胶生成制品中，都必须留有该空腔段。
此外，因颗粒是松散的且具有流动性，如果不对其进行约束，气溶胶生成制品水平放置或倒置时颗粒难免会大规模地流向下游的空腔段，导致插入的加热元件所能直接加热的颗粒大幅减少，释放的香味成分和后续产生的气溶胶量自然也会随着变少，为确保颗粒被充分加热，必须将颗粒约束在加热元件附近的有限空间内。这种约束目前是靠颗粒段上游设置封口膜1和在颗粒段下游提供多通孔固件段20来 实现，两端约束使颗粒不会到处流动。
其中多通孔固件段20材质通常是陶瓷或硅胶，其外壁通过粘合剂牢固粘贴在纸筒内壁上，其中心具有至少一个轴向通孔6，和/或，其外周具有至少一个周缘通气槽7，它们的尺寸均可供烟雾通过但不允许气溶胶源材料颗粒通过，既封堵气溶胶源材料颗粒又能传递烟气。此外，在将电阻发热片或电磁发热片插入到颗粒段中进行中心加热时，多通孔固件段因牢固粘附在纸筒内壁上，还能防止气溶胶源材料颗粒在加热片插入力(因充满的颗粒对加热片插入存在很大阻力，故用户需要对加热片提供一个插入力使其插入)推动下推动多通孔固件段本身向下游移动。但多通孔固件段的存在给颗粒型气溶胶生成制品的工业化制造带来了成本增加和诸多操作上的不便，因此，本领域技术人员一直希望能取消掉该多通孔固件段。但取消多通孔固件段后，在颗粒段下游必须存在空腔段的前提条件下，如何约束颗粒是个难题。
本发明旨在解决上述问题。
发明内容
本发明第一方面公开了一种不使用多通孔固件段的颗粒型气溶胶生成制品，其包括外套筒2、封堵住所述外套筒2的远唇端的封口膜1、插入到外套筒2内部的内套筒3，所述内套筒3底部被可破碎封堵件5封住，该可破碎封堵件5下游是填充有气溶胶源材料颗粒9的颗粒填充段，所述颗粒填下游具有过滤段4，所述可破碎封堵件5在轴向上离开所述封口膜1一段距离以在二者之间形成原生空腔段8。
其中所述上下游是以气体流动方向而确定的。
优选地，所述可破碎封堵件5为可破碎封堵膜，或为所述颗粒段的被压紧的端部。
优选地，所述可破碎封堵件5封堵住所述内套筒3的整个远唇端，这适用于圆柱形内套筒，更适用于底端径向收缩的圆台形内套筒；或者，所述内套筒3的远唇端具有带有底部通孔31的底壁，所述可破碎封堵件5封堵住该底部通孔31，所述底部通孔31的尺寸大于所述气溶胶源材料颗粒9的尺寸，以便于颗粒从该底部通孔漏出到原生空腔段8中。带有底部通孔的方案是更优选的，因为内套筒底壁可以很大程度上防止颗粒从底部通孔再回流到内套筒中。如果使用带尖端的加热元件即加热元件顶部尺寸比主体尺寸更小，还可以在颗粒都流入到原生空腔中后进一步沿轴向推动该加热元件使其主体部分位于底部通孔处，二者之间的间隙进一步能防止 颗粒回流到所述内套筒内。同理，如果所述使用圆台形内套筒，也有同样的防颗粒回流效果。
所述颗粒的填充量可以根据实际需要进行设计，例如可以正好填满原生空腔10而清空内套筒内部空间，这是最优选的，当然也可以在填满原生空间10后还有一部分留在内套筒内部。
所述内套筒3可以以任何方式固定在外套筒2内部，例如靠胶粘剂或摩擦力或二者之间机械结构的配合而固定在外套筒2内部。
优选地，所述外套筒2或内套筒3各自独立地为整体式纸筒。
优选地，所述过滤段4置于内套筒3内或者置于外套筒2内。
优选地，在非加热状态下，所述过滤段4位于所述颗粒段3的紧接下游。当然，如有必要，也可以在颗粒段3和过滤段4之间再留出一个空腔。
本发明第二方面公开了一种气溶胶生成器具-气溶胶生成制品组合套装，其包括带有加热元件的气溶胶生成器具和不使用多通孔固件段的颗粒型气溶胶生成制品，所述加热元件尖端带有倒刺。所述倒刺的作用是能防止颗粒回流到所述内套筒内。
本发明第三方面公开了根据本发明第一方面所述的不使用多通孔固件段的颗粒型气溶胶生成制品的使用方法，其包括如下步骤：用加热元件刺破所述封口膜1后再刺碎所述可破碎封堵件5，使得所述气溶胶源材料颗粒9经由被刺碎处流入到所述原生空腔段8中被所述加热元件加热，所述气溶胶源材料颗粒9原来所占据的空间被空出来而原位形成新的空腔段，用于对气溶胶源材料颗粒9受热后释放的气态香味成分进行冷凝以形成气溶胶，并经过滤段4过滤后离开所述颗粒型气溶胶生成制品。
所述封口膜1可以起到提取器的作用，确保用户抽吸完毕后拔出所述气溶胶生成制品时，该封口膜1兜住所有颗粒一起随气溶胶生成制品被拔出而不是散落在气溶胶生成器具内。
上述技术方案在不矛盾的前提下，可自由组合。
本发明具有以下有益效果：
1、取消了多通孔固件段，但同时仍能对颗粒进行两端约束：存储状态时，靠内套筒上的可破碎封堵件5(必要时配合内套筒底壁)和过滤段4对颗粒进行两端 约束；工作状态时，靠封口膜1和内套筒底壁或加热元件与底部通孔之间的间隙，将颗粒两端约束。
2、原来的颗粒型气溶胶生成制品是四节段制品(从远唇端到近唇端依次为颗粒段、多通孔固件段、空腔段和过滤段)，必须在同一工作现场先后装填四个节段，导致单件成品所耗工时较长。本发明取消掉多通孔固件段首先简化了生产，而且本发明可以事先在A地将颗粒段和过滤段装填到内套筒中组装好后作为独立的预制半成品运到B地再将该内套筒插入到外套筒中即可制得成品，其中A地可以与B地在同一地点或不同地点，劳动分工会导致单件成品所耗工时变短，提高生产效率，也便于生产商将一部分工作进行外包。

具体实施方式
下面通过具体实施方式进一步说明本发明的内容。
实施例1
如图3所示，本发明的不使用多通孔固件段的颗粒型气溶胶生成制品包括外套筒(2)、封堵住所述外套筒(2)的远唇端的封口膜(1)、插入到外套筒(2)内 部的内套筒(3)，所述内套筒(3)底壁具有底部通孔，其被淀粉材质的可破碎封堵件(5)从该通孔下侧封住，该可破碎封堵件(5)下游是填充有气溶胶源材料颗粒(9)的颗粒填充段，所述颗粒填下游具有过滤段(4)，所述可破碎封堵件(5)在轴向上离开所述封口膜(1)一段距离以在二者之间形成原生空腔段(8)。
进一步如图4所示，当用加热元件11刺破所述封口膜(1)后再刺碎所述可破碎封堵件(5)后，所述气溶胶源材料颗粒(9)经由被刺碎处流入到所述原生空腔段(8)中并填满该原生空腔段8，然后被所述加热元件加热，所述气溶胶源材料颗粒(9)原来所占据的空间被空出来而原位形成新生空腔段(10)，用于对气溶胶源材料颗粒(9)受热后释放的气态香味成分进行冷凝以形成气溶胶，并经过滤段(4)过滤后离开所述颗粒型气溶胶生成制品。因为内套筒底壁可以很大程度上防止颗粒从底部通孔再回流到内套筒中。
内套筒底壁可避免颗粒回流到内套筒内；带尖端的加热元件还可以在颗粒都流入到原生空腔中后进一步沿轴向推动该加热元件使其主体部分位于底部通孔处，二者之间的间隙进一步能防止颗粒回流到所述内套筒内；加热元件还可以如图7所示带有倒刺；这三种因素中的任何一种或几种的组合都有助于防止颗粒回流到内套筒内。
实施例2
与实施例1基本相同，区别仅在于可破碎封堵件5正好位于底部通孔处，详见附图5。
实施例3
与实施例1基本相同，区别仅在于内套筒具有内径收缩段，且可破碎封堵件5为经压紧的颗粒封堵层覆盖整个内套筒下端面，详见附图6。该经压紧的颗粒封堵层可耐受正常颠簸而不破碎，在被加热元件刺碎后则整个内套筒下端敞开允许颗粒流下。
以上所述，仅为本发明的具体实施方式，但本发明的保护范围并不局限于此，任何熟悉本技术领域的技术人员在本发明揭露的技术范围内，可轻易想到变化或替换，都应涵盖在本发明的保护范围之内。因此，本发明的保护范围应以权利要求的保护范围为准。

  3. 根据权利要求1所述的颗粒型气溶胶生成制品，其特征在于，所述可破碎封堵件(5)封堵住所述内套筒(3)的整个远唇端；或者，所述内套筒(3)的远唇端具有带有底部通孔(31)的底壁，所述可破碎封堵件(5)封堵住该底部通孔(31)，所述底部通孔(31)的尺寸大于所述气溶胶源材料颗粒(9)的尺寸。
  4. 根据权利要求1所述的颗粒型气溶胶生成制品，其特征在于，所述内套筒(3)靠胶粘剂或摩擦力固定在外套筒(2)内部。
  5. 根据权利要求1所述的颗粒型气溶胶生成制品，其特征在于，所述外套筒(2)或内套筒(3)各自独立地为整体式纸筒。
  6. 根据权利要求1所述的颗粒型气溶胶生成制品，其特征在于，所述过滤段(4)置于内套筒(3)内或者置于外套筒(2)内。
  7. 根据权利要求1所述的颗粒型气溶胶生成制品，其特征在于，在非加热状态下，所述过滤段(4)位于所述颗粒段(3)的紧接下游。
  8. 一种气溶胶生成器具-气溶胶生成制品组合套装，其特征在于，其包括带有加热元件的气溶胶生成器具和不使用多通孔固件段的颗粒型气溶胶生成制品，所述加热元件尖端带有倒刺。
  9. 根据权利要求1所述的不使用多通孔固件段的颗粒型气溶胶生成制品的使用方法，其特征在于，所述方法包括如下步骤：用加热元件刺破所述封口膜(1)后再刺碎所述可破碎封堵件(5)，使得所述气溶胶源材料颗粒(9)经由被刺碎处流入到所述原生空腔段(8)中被所述加热元件加热，所述气溶胶源材料颗粒(9)原来所占据的空间被空出来而原位形成新生空腔段(10)，用于对气溶胶源材料颗粒(9)受热后释放的气态香味成分进行冷凝以形成气溶胶，并经过滤段(4)过滤后离开所述颗粒型气溶胶生成制品。
