一种加热烟支要完成分多段、多次加热抽吸。
在分段加热部一侧设置有与侧出气部出口连通的烟气通道；
烟气通道变向设置、烟气通道变径设置和/或在烟气通道上设置有用于给烟气通道中的烟气进行通入空气的进气入口部。
本实用新型提出一种新型的加热不燃烧烟支及其加热器具，加热烟支的烟纸表面具有（预先或者后开的）多个或一个开孔或槽，一支烟支可分多段进行多次加热抽吸；加热烟具带有侧混气结构；烟支自器具下部反向插入加热器具，采用固定吸嘴进行抽吸。加热抽吸时，被加热烟料段气溶胶在负压作用下经烟支侧开孔释放至加热器具的侧边混气结构中，通过侧气流通道及其连通的吸嘴完成抽吸。用户将一支烟支分为多次（含一次）抽吸完成后，再整体取出烟支丢弃。
本实用新型的烟支结构包括由多段被加热烟料段组成，各加热烟料段之间连续分布或由空腔分割；烟纸表面印刷有（或没有）各加热烟料段区分标识线；烟支下部可包含有用于送入或取出加热器具的提拉段，烟支加热段也可设计为提拉段。烟支圆周介于15~30mm。
烟支侧开孔特征：在各加热烟料段的烟纸外周带有侧向出气孔，出气孔由一个或多个或多组微孔组成；纵向分布或周向分布在烟支表面；出气孔用于释放烟料段加热后产生的烟气气溶胶。侧开孔大小和形态：单段加热段侧开孔总面积>0.2mm2；所述的侧开孔，其形状特征不限于孔、槽、洞等规则形状以及不规则形状，也不限于连通、独立等形态。
侧开孔烟支特征使得加热烟弹段产生的气溶胶，在负压作用下能够从烟支内部经侧出烟孔溢出，改变了现有烟弹产品经烟弹顶面单一出流的模式。侧开孔烟支建立了烟支的多孔并联出流系统，避免了气溶胶的沿程截留、多孔介质的多变影响，创新了加热烟支的气溶胶溢出模式。
开孔方式：出气孔可以是烟支制成为成品时具备，也可以在插入加热器具前进行加工而具备，也可以在插入加热不燃烧器具后，由器具的打孔机构开孔形成。
加热烟料段：烟料段填充有不规则的丝状、片状、颗粒状加热基质，基质中含有丙三醇、丙二醇、致香成分等物质。加热段也可作为提拉段，用于将烟支插入或取出加热器具。
加热烟料段无需规则有序的排列方式、特殊的再造烟叶处理工艺，采用现有常规的卷烟制丝（包括润叶加料、切丝、烘丝、加香加料等工序）、卷制（包括卷接、包装等工序）工艺即可完成。提拉段可用烟料段代替，也可使用环保的纸基纤维等材料制作，大大降低了烟支的材料成本和生产成本。
卷烟纸特征：包裹烟支的卷烟纸类型可以包括传统卷烟纸或铝箔纸、硅油纸、用麻浆/木浆或草浆制成的盘纸或带有防油或耐油特性的防油纸等材料。卷烟纸可预先开孔，用于卷制带有侧出气孔的加热不燃烧烟支。
提拉段：烟支可设计为带有提拉段，与加热段首尾连接，具有透气性。提拉段可由空管、纸基嘴棒或植物纤维等制作而成，可包含带有增香功能的香精香料、爆珠等。
卷制方式：烟料段采用传统的制丝、卷包工艺完成；带有提拉段的烟支可采用传统的滤嘴卷接生产工艺完成。
加热器具总体特征：由支持多段加热的加热部件、侧向气流混气结构、固定吸嘴、电路控制板、电源部件等模块组成。侧向气流混气结构位于加热模组的侧边，加热释放的气溶胶，经由侧向气流混气结构和吸嘴进入吸食者口中。
加热器具与加热烟支共同组成了一个面向多孔介质、多孔出流、热温传导、节流膨胀、降温雾化、气溶胶分子聚合等多维度技术特征的复杂热流控制系统，整体保证了在多变阻力、多因素紧耦合环境下的热流一致性性能。
侧向气流混气机构：加热部件带有侧向出气结构，侧向出气结构形状为槽或孔；侧向出气结构旁边为气流空腔，气流空腔的外侧带有外界空气进气结构；加热部件侧向出气结构、气流空腔与外界进气结构形成混气机构。气流空腔的侧边或上部设计有气流通道，通道与吸嘴连通。
气流混气模式：加热抽吸时，混气机构以及烟支烟料段形成负压，负压施加于侧向开孔的烟支的侧孔，将气溶胶物质释放至器具的气流空腔，与外界空气混合后，经由气流通道进入吸嘴部分。
在该侧向混气机构和混气模式下，基于建立的多歧管沿程泄流仿真模型、热外场气液固多相膨胀时间序列预测方法以及混气机构压力损失函数等，使得各烟弹段在独立加热抽吸模式下，能获得良好的气溶胶溢出能力和雾化性能，取得了流体、热力、化学多维度的技术协同，保证了烟支加热抽吸的感官特性与多段口感一致性。
加热模式：加热部件具有多个可被独立控制的加热区，电路板和软件算法对被加热烟料段的对应加热区进行单独加热控制。再次加热抽吸时，自动切换到下一段加热区进行加热控制。
作为扩展，独立加热控制方案设计了电阻温升关系模型、自适应PID控制算法、动态温度曲线优化方法以及功耗优化方法等，解决了多温区串联结构下的测温不准、温控波动大、温度超调跑飞、功耗过大等问题，避免烟支加热过度、加热不足、热耗散过多等诸多影响感官质量的缺陷。
 有益效果
本实用新型采用烟支设计为多段、多次加热抽吸模式，完全改变了1支烟支加热抽吸1次的模式，大幅提升了抽吸体验，大大降低了烟支成本和消费成本。烟支侧边出气的负压释放机制，保障了多段抽吸的感官质量体验一致性，避免了烟气上行截留问题，为加热烟支设计提供了全新的技术思路。加热器具的侧边气流混气机构，实现了流体、热力、烟气化学的有机融合，创新了气溶胶雾化机理，形成了更具满足感、香气丰富的抽吸体验。多段式、分区加热、便于自动分段切换的加热温控模式，实现了1支烟支多次加热抽吸，大幅提高了烟支利用率、功耗控制和用户操作体验。本实用新型烟支无需降温段、过滤段，解决了当下加热卷烟结构复杂、不可降解等技术难点，并采用传统卷烟生产工艺，大幅降低了烟支材料成本与生产成本，极大降低了传统卷烟企业向加热不燃烧产品迁移的成本。
本实用新型设计合理、成本低廉、结实耐用、安全可靠、操作简单、省时省力、节约资金、结构紧凑且使用方便。

如图1所示，本实施例的加热不燃烧烟支，包括连接设置的提拉段1与烟弹段2；其可以是常规烟支或新作的烟支，烟支、烟弹中的烟可以是其他植物加热物料，均属于保护范围。
烟弹段2为若干段，可以是三段或其他；
在相邻烟弹段2之间设置有间隔部4或相邻烟弹段2直接连接；间隔部4可以是中空部，也可以台阶等，从而实现物理隔离，减少热传导，方便掰开，避免因为掰断时候造成烟丝散落分散，可以是划线，方便剪断。
在烟弹段2插入加热器具加热之前或之后，烟弹段2具有侧出烟孔3，方便透气，从而烟弹段2用于加热后释放烟气气溶胶；
烟弹段2用于加热后从侧出烟孔3释放烟气气溶胶，这是现有技术所不具备的，其实现侧向排出烟气，减少了烟气在整个烟支中的流动；
各烟弹段2独立加热或组合加热，均是保护范围，可以根据所需烟气排放量调整；
侧出烟孔3在烟弹段2的外壁上；例如烟纸上，烟管上或烟锡纸上等。
侧出烟孔3连通加热物料与外界；实现透气，其可以多个，螺旋的，线性分布以及离散分布的，可以是槽、孔等。
提拉段1为中空管或内置有过滤部5、作为具有侧出烟孔3的烟弹段2或不具有侧出烟孔3的烟弹段2，可以是滤嘴等其他外露的部分或其他类似均构成侵权。
在烟弹段2中设置有烟丝，也可以根据自己所需选择添加物。
如图1-图4、图8，本实施例的加热不燃烧烟支的加热器具 ，包括壳体部6，一般采用保温隔热结构；在壳体部6上设置有分段加热部11，实现了加热所需段，而不是需要每次需要剪断加热后的加热段；分段加热部11的一端用于插入分段加热烟支12的烟支物料段13；
分段加热部11具有加热内腔22，以容纳烟支，对其进行加热产生烟气；
在加热内腔22的内侧壁上设置有至少进口与加热内腔22连通的侧出气部25；其优选为三个，加热对应段的烟支产生的烟气从对应的侧出气部25侧向输出，避免加热的烟气对其他段的烟丝产生影响。
在加热内腔22的内侧壁与烟支的外侧壁之间设置有通气间隙23；在分段加热部11一侧设置有与侧出气部25出口连通的气流汇集腔24，气流汇集腔24至少用于汇集加热内腔22中烟支产生的烟气，其空间变化，使得烟气实现扩散，避免聚集，提高吸烟体验，同时，实现降温其混合的空气来源可以是从间隙或其他位置补入空气；
气流汇集腔24连通有侧旁通孔16的进口；侧旁通孔16出口连通有侧向气流通道9的进口；气流汇集腔24中汇集的烟气通过侧旁通孔（16）输出给侧向气流通道9；其实现了对气流的进行节流整流，实现烟气与空气的混合。
分段加热烟支12为加热不燃烧烟支；在分段加热部11一侧连通有侧旁通孔16，从而实现烟气流通；在侧旁通孔16连通有侧向气流通道9，在侧向气流通道9出口处设置有烟气输出通道8，在烟气输出通道8上设置有吸嘴部7，从而实现烟气流通。
在分段加热部11、侧旁通孔16或侧向气流通道9连通有进气入口部10，用于进入空气；优选为设置在侧向气流通道9进口处，从而实现对气流的二次整流雾化；
分段加热部11电连接有电路控制板14，在壳体部6内腔中设置有电池15，实现电路控制。
侧出气部25沿加热内腔22长度方向间隔设置，用于对应分段加热烟支12不同位置的烟弹段2；从而实现了烟气侧向出气，实现分段加热。
侧出气部25与相应的侧出烟孔3对应，从而实现侧向快速排气，阻力小。
在加热内腔22的内侧壁与烟支的外侧壁之间设置有通气间隙23，其根据不同烟支外径，其间隙大小有所差异，实现了补入空气；
侧出气部25采用通透的槽和/或孔等透气通道。  
作为一改进，在分段加热部11另一端设置有烟道端口，在烟道端口设置有顶部扣盖17；在壳体部6上配套有工艺豁口18，用于作为进气入口部10和/或打开顶部扣盖17的工艺空间。 烟道端口用于通过加热后的烟弹段2。其通过豁口实现进气，当需要将加热后烟弹，直接从该端口取出，实现一进一出，从而避免插拔的麻烦，避免因为插拔使得烟支断在加热腔中，通过工艺豁口18方便手扣打开。
作为一改进，在侧向气流通道9出口处设置有第一斜面套座19，在第一斜面套座19的斜面上垂直设置有斜向中间管20，在斜向中间管20连接有第二斜面转体管21的斜面；为了满足不同抽食方式，使得第二斜面转体管21以斜向中间管20轴心线旋转，从而满足吸嘴部7的不同角度设置。
第二斜面转体管21连接有烟气输出通道8。
作为一改进，分段加热部11的插入烟弹段2一端与吸嘴部7在壳体部6上同侧设置，相比于传统从下部插入烟支的问题，从上部插入，避免烟支因为插入间隙过大，导致烟支掉落，当然为了避免烟支在加热时挡碍，也可以将吸嘴或烟支斜向设置构成等同。
