Abstract

本发明公开一种加热不燃烧型气溶胶生成装置，包括装置主体（1）、位于主体（1）内的容纳筒（2）和加热部（3）；容纳筒（2）具有底壁（22）；加热部（3）具有底端（32）；加热部（3）底端（32）在垂直高度上高于容纳筒（2）底壁（22）的高度，以使得加热部（3）底端（32）在垂直高度上高于气溶胶生成制品的气溶胶生成基质一侧的端面，从而保证气溶胶生成制品的气溶胶生成基质底端一侧部分区域不会被加热部围绕，从而使得此段的温度较低，几乎不产生气溶胶，这也就避免停止抽吸后，此段气溶胶冷凝并流出污染加热管的底壁的问题。另外，本发明气溶胶生成制品中气溶胶生成基质段（82）远离滤嘴段（84）的一端还具有紧密段（81）。

Description

一种加热不燃烧型气溶胶生成装置及包含其的气溶胶生成系统 技术领域
本发明专利涉及低温加热不燃烧气溶胶生成装置生产技术领域，具体涉及一种加热不燃烧型气溶胶生成装置及包含其的气溶胶生成系统。
背景技术
加热不燃烧气溶胶生成基质的加热温度一般在250-350℃之间，相对于普通燃烧卷烟，加热不燃烧气溶胶生成制品在保留传统卷烟口味的同时可大幅度减小气溶胶生成基质中的有害物质对抽吸者的伤害，不发生高温燃烧裂解过程，从而减少了气溶胶生成基质中焦油和有害物质的释放量，可大幅度降低二手烟的危害。
目前对气溶胶生成制品进行加热的加热技术通常包括电阻加热或电磁加热，而发热体的形态又通常包括管状的用于围绕气溶胶生成制品进行加热的加热管或片/针状的用于插入气溶胶生成制品的进行加热的加热片/加热针。对于电阻加热的发热体，其通过发热体上的电阻线路通过电时产生热量而加热气溶胶生成制品，而对于电磁加热的发热体，其通过感应磁场而产生电流并发热来加热气溶胶生成制品。现有的用于加热不燃烧的气溶胶生成制品包括用户嘴部抽吸的滤嘴段和远离滤嘴段的气溶胶生成基质段，气流可从气溶胶生成基质段的端面进入气溶胶生成制品并出滤嘴段的端面流出。这样带来的问题是，无论是通过加热管还是通过加热片/加热针对气溶胶生成基质进行加热，一方面，当用户不进行抽吸时，仍有少量冷空气通过气溶胶生成基质段的端面进入气溶胶生成基质段中，气溶胶生成基质段中被雾化的一小部分气溶胶遇到冷空气被冷凝，形成液体从气溶胶生成基质段的端面流出而污染器具，另一方面，在用户抽吸时，气溶胶生成基质段的负压较低使气溶胶流向滤嘴段，但用户不抽吸时，缺少了用户的抽吸力，在负压作用下，导致小部分气溶胶从滤嘴段向气溶胶生成基质段的方向流动，并在冷凝时，形成液体从气溶胶生成基质段的端面流出而污染器具。
除此之外，现有的通过加热管对气溶胶生成制品进行加热的加热不燃烧型气溶胶生成装置中，通常加热管的底端与气溶胶生成基质的底端平齐，且加热管的底壁面支撑气溶胶生成基质的底端面，此时加热管的对气溶胶生成基质底端(与滤嘴远离的一端)进行加热，这样在停止抽吸后，气溶胶生成基质段底端被雾化 产生的气溶胶来不及被抽吸，会冷凝从气溶胶生成基质段端面流出污染加热管底部，进一步的，如果此时还有外界空气从气溶胶生成基质段端面进入，气溶胶生成基质段底端被雾化产生的气溶胶预冷更容易冷凝并流出污染加热管的底壁。
因此，避免已经被雾化的气溶胶再次冷凝，是避免污染器具的一个重要方法。
为了解决以上问题，提出本发明。
发明内容
本发明提供一种加热不燃烧型气溶胶生成装置，其特征在于，包括装置主体1、位于所述主体1内的用于容纳气溶胶生成制品的容纳筒2和用于加热所述气溶胶生成制品以产生气溶胶的加热部3；

所述加热部3底端32在垂直高度上高于所述容纳筒2底壁22的高度。此处，限定所述加热部3底端32在垂直高度上高于所述容纳筒2底壁22的高度的目的在于，当所述容纳筒2没容纳有气溶胶生成制品后，加热部3底端32在垂直高度上高于气溶胶生成制品的气溶胶生成基质一侧的端面。
优选地，所述加热部3为与所述容纳筒2分开设置的加热管，其与所述容纳筒2共同收容气溶胶生成制品。也就是说，所述加热管和所述容纳筒2是两个单独的部件。

优选地，所述容纳筒2的顶部开口21处设置有用于导入气溶胶生成制品的导向管4。
所述容纳筒2的底壁22可以对收容的气溶胶生成制品的气溶胶生成基材一侧的端面至少部分密封，以防止或降低气体经气溶胶生成基材一侧的端面进入气溶胶生成基材内。此处需要说明的是，所述底壁22可以对气溶胶生成基材一侧的端面至少部分密封，是可选的，当收容的气溶胶生成制品的气溶胶生成基材一侧的端面自带有密封件时，所述底壁22对该端面的至少部分密封设置可以省略也可以保留。但是当收容的气溶胶生成制品的气溶胶生成基材一侧的端面不带有密封件，也就是说气体可以不受阻碍的经此端面进入气溶胶生成基材时，所述底壁22对该端面的至少部分密封设置需要保留。
优选地，所述加热不燃烧型气溶胶生成装置为电磁型加热装置，所述加热部3外围缠绕有线圈5，所述线圈5可产生电磁感应，所述加热部3可接收所述线圈5产生的电磁感应而发热，所述加热部3选自但不限于电磁性金属材料；所述加热部3和所述线圈5之间具有隔热结构6，所述隔热结构6与所述加热部3间隔设置。

本发明第二方面提供一种气溶胶生成系统，其包括本发明第一方面所述的加热不燃烧型气溶胶生成装置，以及气溶胶生成制品8。
优选地，所述气溶胶生成制品包括紧密段81、气溶胶生成基质段82、气道段83和滤嘴段84；
所述气道段83位于所述气溶胶生成基质段82和所述滤嘴段84之间；
所述紧密段81位于所述气溶胶生成基质段82远离所述滤嘴段84的一端；
所述气道段83具有轴向贯穿所述气道段83的气流通道831；
所述紧密段81的轴向透气度小于所述气溶胶生成基质段82的轴向透气度。优选地，所述紧密段81的轴向透气度为0，即不允许气体轴向通过。
所述紧密段81、气溶胶生成基质段82、气道段83和滤嘴段84为通过包裹件卷制形成所述气溶胶生成制品中的各段，或者通过灌装入一体成型的管件中装填形成所述气溶胶生成制品中的各段。
优选地，所述加热部3底端在垂直高度上高于或者齐平于所述紧密段81与所述气溶胶生成基质段82连接处。
优选地，所述紧密段81选自非气溶胶生成材料，选自但不限于碳纤维材料、金属膜片、陶瓷或高分子材料；所述高分子材料选自但不限于聚乙烯、聚丙烯、聚氯乙烯、聚对苯二甲酸乙二醇酯或聚乳酸。
或者，所述紧密段81与所述气溶胶生成基质段82材料相同，均选自气溶胶生成材料，所述紧密段81的堆积密度大于所述气溶胶生成基质段82的堆积密度。也就是说，此时紧密段81的材料和气溶胶生成基质段82材料一致，均是气溶胶生成材料，但是两端的紧实度完全不一致，所述紧密段81的密度大于所述气溶胶生成基质段82的密度。所述紧密段81的轴向透气度小于所述气溶胶生成基质段82的轴向透气度。当紧密段81为气溶胶生成材料时，其可在气溶胶生成基质制造过成中可以与气溶胶生成基质段82一体形成，并且通过压紧工艺形状高密度气溶胶生成基质段作为紧密段81，制造简单。
优选地，所述气道段83是中空的，其具有侧壁和中空腔，所述中空腔为轴向贯穿所述气道段83的气流通道831；所述气道段83为圆柱体状，采用醋酸纤维材料制成。
优选地，所述气道段83的侧壁上还具有贯通所述侧壁的侧流孔832；所述侧流孔832的轴向位置靠近所述气溶胶生成基质段82的位置而远离所述滤嘴段84的位置；更加靠近所述气溶胶生成基质段82的位置的原因是，侧流孔832的轴向位置越靠近所述气溶胶生成基质段82，越容易从气溶胶生成基质段82提取出气溶胶。所述侧流孔832的数量可以为但不限于6-8个。
优选地，所述气道段83包括靠近所述气溶胶生成基质段82的第一气道段833和靠近所述滤嘴段84的第二气道段834；所述第一气道段833和第二气道段834可以是一体的，也可以是可分离的两段。
所述第一气道段833的气流通道831的横截面积小于等于或者大于述第二气道段834的气流通道831的横截面积。当所述气道段83是中空的时，其具有侧壁和中空腔，所述中空腔为轴向贯穿所述气道段83的气流通道831。第一气道段833的中空腔体内径小于等于或者大于所述第二气道段834的中空腔体内径，此时两者连接处可以是锥形斜面，也可以是垂直断面，既可以是平角，也可以是具有倒圆角结构。当第一气道段833的中空腔体内径大于第二气道段834的中空腔体内径时，第一气道段833引入的空气量更多，对气溶胶的提取作用更好，气溶胶量更大。而当第一气道段833的中空腔体内径小于第二气道段834的中空腔体内径时，第二气道段834可以汇聚更多的气溶胶，对气溶胶的冷凝效果更好，气溶胶降温效果更好，更加适合抽吸。
优选地，当所述加热不燃烧型气溶胶生成装置为电磁型加热装置时，所述气溶胶生成基质段82内还具有沿轴向设置的金属片7，中间的金属片7也可以感受线圈产生的电磁而发热。
优选地，所述气道段83为圆柱体状，选自但是不限于醋酸纤维材料、高分子材料制成。
气溶胶生成基质段82内含有气溶胶生成材料，所述气溶胶生成材料为颗粒或丝状形式的气溶胶生成材料。
此处，只是举例说明气溶胶生成材料的形式，但实际并不限定于以上几种形式，只要是能产生气溶胶的气溶胶生成媒介均适用。
本发明中气溶胶生成制品总长度可以为30-80mm，其中紧密段的范围为2-10mm，优先为5mm，气溶胶生成基质段82的长度为8-25mm，优选为12mm，气道段83长度为10-20mm，优选为15mm，滤嘴段84长度为8-15mm，优选为10mm。
在不冲突的前提下，以上优选方案可以自由组合。
相对于现有技术，本发明具有以下有益效果：
1、本发明加热不燃烧型气溶胶生成装置包括装置主体1、容纳筒2和加热 部3；所述加热部3底端32在垂直高度上高于所述容纳筒2底壁22的高度，以使得加热部3底端32在垂直高度上高于气溶胶生成制品的气溶胶生成基质一侧的端面。这样保证气溶胶生成制品的气溶胶生成基质底端一侧部分区域不会被加热部围绕，从而使得此段的温度较低，几乎不产生气溶胶，这也就避免了停止抽吸后，此段未被抽吸掉的气溶胶冷凝并从端面流出污染加热管的底壁的问题。
2、在本发明优选地实施方案中，所述容纳筒2的底壁22可以对收容的气溶胶生成制品的气溶胶生成基材一侧的端面至少部分密封，以防止或降低气体经气溶胶生成基材一侧的端面进入气溶胶生成基材内。从而可以防止冷空气通过气溶胶生成基质段的端面进入气溶胶生成基质段中，气溶胶生成基质段中被雾化的一小部分气溶胶遇到冷空气被冷凝，形成液体从气溶胶生成基质段的端面流出。
3、本发明中所述加热管和所述容纳筒2可以是两个单独的部件，两个部件同轴设置，且在垂直方向上可以有部分重叠，也可以是完全分开的两段。另外，所述加热管和所述容纳筒2也可以是一体的，所述加热部3为所述容纳筒2的一部分。即，所述容纳筒2靠近顶端的部分具有发热的功能，既作为收容气溶胶生成制品的容纳筒，又作为加热气溶胶生成制品的加热部，结构更加简单，易于实施。
4、在本发明优选地实施方案中，使用的气溶胶生成制品8在气溶胶生成基质段82远离所述滤嘴段84的一端设置紧密段81，而所述紧密段81的轴向透气度小于所述气溶胶生成基质段82的轴向透气度，可以降低和防止空气经所述紧密段81进入所述气溶胶生成基质段82，从而可以防止冷空气通过气溶胶生成基质段的端面进入气溶胶生成基质段中，气溶胶生成基质段中被雾化的一小部分气溶胶遇到冷空气被冷凝，形成液体从气溶胶生成基质段的端面流出。
4、现有技术中，抽吸过程中气溶胶生成基质段的端部有气体通过，气溶胶生成基质段在抽吸过程中处于负压的状态，所以停止抽吸的瞬间，会发生未被抽吸走的气溶胶从滤嘴段逆流向气溶胶生成基质段的问题。
但是当气溶胶生成基质段前面加上紧密段后，在用户抽吸过程中，由于外界气体几乎不能通过紧密段补充进入气溶胶基质段，因此气溶胶基质段的负压不会上升，可以防止停止抽吸时，气溶胶倒流至气溶胶基质段并从气溶胶生成基质段的端面流出，进一步解决气溶胶冷凝液从气溶胶生成基质段的端面流出而污染器 具的问题。
5、在优选地实施方案中，所述紧密段81选自非气溶胶生成材料，选自但不限于碳纤维材料、金属膜片、陶瓷或高分子材料，或者所述紧密段81选自气溶胶生成材料，所述紧密段81的密度大于所述气溶胶生成基质段82的密度，材料选择范围广，另外，当紧密段81为气溶胶生成材料时，其可在气溶胶生成基质制造过成中可以与气溶胶生成基质段82一体形成，并且通过压紧工艺形状高密度气溶胶生成基质段作为紧密段81，制造简单。
6、在优选地实施方案中，所述气道段83的侧壁上还具有贯通所述侧壁的侧流孔832，该侧流孔的设置便于用于抽吸气溶胶，以减小抽吸时的吸阻。
7、在优选地实施方案中，所述侧流孔832的轴向位置靠近所述气溶胶生成基质段82的位置而远离所述滤嘴段84的位置，该侧流孔引入的空气对于气溶胶生成基质段82产生的气溶胶具有提取作用。
8、在优选地实施方案中，所述气道段83包括靠近所述气溶胶生成基质段82的第一气道段833和靠近所述滤嘴段84的第二气道段834。所述第一气道段833的气流通道831的横截面积小于等于或者大于述第二气道段834的气流通道831的横截面积；当所述气道段83是中空的时，其具有侧壁和中空腔，所述中空腔为轴向贯穿所述气道段83的气流通道831。第一气道段833的中空腔体内径小于等于或者大于所述第二气道段834的中空腔体内径。
当第一气道段833的中空腔体内径大于第二气道段834的中空腔体内径时，第一气道段833引入的空气量更多，对气溶胶的提取作用更好，气溶胶量更大。
而当第一气道段833的中空腔体内径小于第二气道段834的中空腔体内径时，第二气道段834可以汇聚更多的气溶胶，对气溶胶的冷凝效果更好，气溶胶降温效果更好，更加适合抽吸。

实施例7
本实施例使用的加热不燃烧型气溶胶生成装置与实施例1一致。区别在于气溶胶生成制品不同。
如图7所示具有紧密段的气溶胶生成制品8，其结构与实施例1的区别在于：所述紧密段81选自气溶胶生成材料，所述紧密段81的密度大于所述气溶胶生成基质段82的密度。也就是说，此时紧密段81的材料和气溶胶生成基质段82材料一致，均是气溶胶生成材料，但是两端的紧实度完全不一致，所述紧密段81的密度大于所述气溶胶生成基质段82的密度。所述紧密段81的轴向透气度小于所述气溶胶生成基质段82的轴向透气度。
紧密段81在气溶胶生成基质制造过成中可以与气溶胶生成基质段82一体形成，并且通过压紧工艺形状高密度气溶胶生成基质段作为紧密段81，制造简单。
