Description

一种烟芯段加香的气溶胶产生制品 技术领域
本发明涉及加热不燃烧卷烟技术领域，具体涉及一种烟芯段加香的气溶胶产生制品。
背景技术
随着消费者对于健康问题的重视及对卷烟产品个性化体验的需求提升，烟草行业不断响应消费者的需求升级，开发出各种具有降焦减害的吸烟制品。其中，加热不燃烧型卷烟由于其卷烟加热方式不同于传统卷烟制品，使其能够在满足消费者对于卷烟产品的感官需求的同时提供更加健康的抽吸体验。
现有气溶胶产生制品主要包括发烟芯材段、支撑段、降温段和滤嘴段，其中支撑段不仅对吸烟制品起到支撑的作用，更主要的是汇聚烟气并协助降温段对烟气降温。现有技术通过在线激光打孔的方法打穿支撑段管壁、包裹管壁的成型纸(5)和接装纸(6)形成通风孔，使外界空气进入支撑段内部与烟气混合，从而增加烟雾量，有效降低烟气温度，但是其对烟气的降温效果和使空气与烟气的混合效果仍然不佳，原因在于以下两点：1、支撑段的管壁径向支撑力不足，管壁受到外力后向管腔中心塌陷，造成烟气和空气的气流通道被堵塞及烟雾量不足的问题；2、烟气与支撑段管壁的接触面积有限，不能实现有效的降温；3、烟气和空气在支撑段中停留时间短，烟气和空气直接快速通过支撑段进入降温段，不能达到充分混合。因此，为了进一步实现对烟气的降温，目前主要是针对降温段的降温材料进行改进或者直接增加降温材料的用量，但降温材料多为相变材料，在抽吸几口后，相变材料缩塌并堵住气流通道，吸阻大幅度升高，影响抽吸体验。
除此之外，现有气溶胶产生制品增香一般通过烟草材料、滤嘴、卷烟纸载香，载香工艺难度大、效率低并且香味释放不稳定。更关键的是，很多香料的挥发性强，用户在打开包装后，这些特征香味很容易散失，导致每包后面几支卷烟没有香气品质差。
为了解决以上问题，提出本发明。
发明内容
本发明采用前置爆珠的方式，使用气溶胶产生制品时，自动加香，提高加香效率和释香的稳定性。同时本发明支撑段2再次补香，透气中空段3引入空气， 可以降低吸阻，提升舒适性，进一步保证烟雾量和适宜的烟气温度。

本发明气溶胶产生制品既适用于周向型气溶胶产生制品烟具，也适用于中心型气溶胶产生制品烟具，只要是烟芯材料段的温度可以达到加香胶囊11破裂的温度即可。
相对于现有技术，本发明具有以下有益效果：
1、本发明首次将加香胶囊11放置到所述发烟芯材段1下游支撑段2紧邻所述发烟芯材段1一端的端部，且所述加香胶囊11的囊壁选自可以在150-200℃的环境温度下破裂的材料，这就使得不进行抽吸时，由于囊壁的保护，加香胶囊11内部的香味物质并不会释放出来，且加香胶囊放置到支撑段2的加香小孔21 中，由于支撑段2管壁以及成型纸5的保护，进一步避免了长期放置时香味物质的损失。另外，本发明的加香胶囊11并非同现有爆珠一样，需要消费者捏破从而使内部的加香物质释放，而是选自在80-200℃的环境温度下破裂的材料作为囊壁，消费者在进行抽吸时，烟芯材料段的温度最高，在120℃左右，当热烟气到达支撑段2后，部分烟气顺着中空大孔22进行汇集，少量烟气通过加香小孔，当进入加香小孔21中的烟气达到囊壁破裂温度时，加香胶囊自然破裂。采用加香胶囊受热破裂的好处是：①恰好利用加香胶囊11在支撑段2紧邻所述发烟芯材段1一端的端部的优势，如果在其他段，温度达不到破裂温度；②之前爆珠多是添加到醋纤滤嘴段，由于支撑段管壁的回弹性远不如醋纤，捏破爆珠后醋纤回弹，几乎无形变，而如果通过支撑段管壁捏破爆珠，支撑段会发生变形，以至于改变了支撑段结构和气流通道，影响抽吸效果，带来不好的消费体验，而受热破裂完美解决了此问题；③加香胶囊11的囊壁受热破裂可以进一步降低烟气的温度。
进一步的，本发明在所述发烟芯材段1下游支撑段2紧邻所述发烟芯材段1一端的端部放置加香胶囊11，而非在发烟芯材段1内部放置加香胶囊11的原因和优势在于：消费者在进行抽吸时，烟芯材料段的温度最高，在120℃左右，如果将加香胶囊11放置到烟芯材料段，由发烟材料包裹，则在抽吸过程中，加香胶囊11会受到持续高温，导致加香胶囊11的囊壁迅速破裂，内部的香精香料迅速挥发，这样就导致一方面抽吸前几口香味浓厚，而后几口烟气几乎没有增香的效果。另一方面，由于加香胶囊11受到的温度高，虽然囊壁确实更容易破裂，但是加香胶囊11内部有一些挥发温度较低的香精香料，比如薄荷醇、橙油、玫瑰精油等，这样就产生了囊壁需要一定温度破裂，但是温度过高囊壁内的低挥发温度香精香料会瞬间挥发的两难问题。
本发明将加香胶囊11放置到所述发烟芯材段1下游支撑段2紧邻所述发烟芯材段1一端的端部，且是放到支撑段2的加香小孔中，由于支撑段2此端部靠近所述发烟芯材段1，所以所述发烟芯材段1过来的烟气仍然具有较高的温度，可以达到使加香胶囊11破裂的程度。但是由于加香胶囊11在支撑段2的加香小孔中，发烟芯材段1过来的烟气大部分会进入中空大孔22中，仅有少量烟气进入加香小孔中，这些少量的烟气在加香胶囊11囊壁吸热破裂后温度已经降低， 不会使加香胶囊11内部的香精香料迅速挥发，从而达到稳定缓释香气的效果。
结合此支撑段的结构，本发明将支撑段2下游的透气中空段3打孔，形成引入空气的通气孔，而并非如现有技术一样在支撑段2的管壁上打孔引入空气，这样的原因和效果在于：不在支撑段2打孔引入空气可以首先保证支撑段2内部的加香胶囊11可以有足够的烟气温度破裂加香，而在烟气已经初步降温加香后，进一步从透气中空段3引入空气，可以进一步降温和汇聚烟气。
2、本发明所述发烟芯材段1由防渗卷烟纸12包裹而成，在烟支存放过程中发烟材料内的水分，渗到所述卷烟纸管外侧，产生黄斑，所以需要对装填发烟材料的卷烟纸管内壁添加防水层。防水层可以防止发烟材料内的水分，渗到所述卷烟纸管外侧。
同样的，发烟材料中会添加发烟剂等，长时间放置过程中，发烟材料中的发烟剂会携带香精香料渗透到纸管外侧，产生黄斑，影响纸管外观，而由于发烟剂是油性的，所以需要对填发烟材料的卷烟纸管内壁添加防油层。防油层可以防止发烟材料中发烟剂携带香精香料向纸管外壁渗透，防止黄斑的产生。
更为关键点，本发明在所述发烟芯材段1下游支撑段2紧邻所述发烟芯材段1一端的端部放置加香胶囊11，所以所述成型纸5靠近所述支撑段2一侧具有防渗层，抽吸过程中，待囊壁破裂后，加香胶囊11内部的香味物质也有可能渗透到支撑段2管壁，而防渗层可以避免香精香料渗到成形纸上的问题。
3、本发明支撑段2具有加香小孔21和中空大孔22，其中加香小孔21用于加香，中空大孔22用于汇聚烟气。部分加香小孔21内靠近所述发烟芯材段1一侧端部具有加香胶囊11，可以控制加香胶囊11的添加量。中空大孔22可以用来汇聚烟气，减小对烟气的吸附，增加烟雾量。另一方面，所述加香小孔21分散在所述中空大孔22外侧，加香更加均匀。
4、本发明气溶胶产生制品还包括中空结构的支撑段2，其中支撑段不仅能够对气溶胶产生制品起到支撑的作用，更主要的是汇聚烟气并协助降低烟气的温度，解决进入吸烟者口腔的温度高，烟气烫嘴的问题。
5、本发明透气中空段3上具有通风孔31，在本发明所述通风孔31和现有技术在支撑段上打的孔形状和尺寸均一致的情况下，本发明所述通风孔31距离吸烟者嘴端更近，故通风孔31处的吸力明显大于现有技术在支撑段上打的孔处 的吸力，所以本发明所述通风孔31的通风效果更好，引入的环境空气的量更大，从而更利于降低烟气温度。同时，本发明烟支支撑段2具有空腔，透气中空段3也具有空腔，引入的空气可以更好的和烟气接触混合，进一步降低烟气温度。本发明在降温段打孔而非支撑段，从而进一步利用吸力的变化来增加空气进量，降低烟气温度。

从表1可以看出，气溶胶产生制品样品1和气溶胶产生制品样品2在香气香味、刺激性改善、口感等方面都有不同程度的增加，且气溶胶产生制品样品1和气溶胶产生制品样品2在加热过程中，产生的烟雾量充足，满足吸烟者需求。
