Description

一种具有感应加热堵头的加热卷烟烟支及其适配烟具 技术领域
本发明属于烟草技术领域，具体涉及一种具有感应加热堵头的加热卷烟烟支及其适配烟具。
背景技术
近年来，随着全球控烟形势加剧以及消费者健康意识提升，非燃烧、低危害的加热不燃烧卷烟获得了各国烟草企业的关注。加热不燃烧卷烟通过外源加热烟草无需点燃烟草，温度通常维持在400℃以下，远低于传统卷烟燃烧温度的600至900℃，减少了约90％燃烧产生的有害物质，同时侧流烟气和环境烟气释放量也大幅度降低。
现有技术用于加热不燃烧卷烟的加热方式主要是电阻式周向加热和中心加热。周向加热一般利用不锈钢管外包柔性电路板来实现加热卷烟烟支的周向加热，热量从烟支外周向内部传导；但不可避免地存在热量向外侧扩散的问题，导致烟具热利用效率低、加热速率慢。中心加热通常以陶瓷厚膜片或圆柱体发热棒作为加热元件，刺入加热卷烟烟支中进行中心加热，热量从烟支的内部向外周传导，烟具热利用效率高、加热速率快；但加热元件易折断损坏，同时加热元件上的发热电路与烟草烟芯大面积接触，加热过程中产生的焦油类物质容易在加热元件的外表面上烧结粘附，进而会使加热元件的电热性能大打折扣。以上两种电阻加热烟具还共同存在以下问题：靠近热源部分的烟草烟芯由于受热过度极易出现碳化的现象，而远离热源部分的烟草烟芯又因为加热不充分导致香气及有效成分释放量不足；同时因碳化掉落的烟丝、烟末等也不易清洁。
为解决电阻加热方式的弊端，新推出了电磁加热方式的烟具及配套烟支。电磁加热方式的烟具加热速率快，使用方便；配套烟支主要由滤嘴段、降温段、包裹感应芯的烟草烟芯段、堵头等四部分组成；堵头为醋纤基棒，可以有效防止烟芯及感应芯掉落、同时截留焦油类物质；电磁加热方式的烟具还具有使用后易清洁的优点。但该电磁加热方式的烟具存在以下问题：1、烟具加热时热量从感应芯由内向外传导，加热均匀性不好，导致烟草芯的利用率不高，香味释放不充分， 逐口稳定性差。2、由于配套烟支的烟芯段中央包裹感应芯，配套烟支生产时烟丝只能有序填充，且需要使用专用卷烟设备，烟草生产企业无法利用现有的传统卷烟生产设备进行配套烟支的生产。
为解决上述问题提出本发明。
发明内容
