如图2和图3所示，圆台包括背向设置的顶面23和底面24，顶面23的直径小于底面24的直径，加热体21安装在顶面23上，第二连接端13内设置有与圆台的外侧壁密封配合的渐缩形空腔结构14。本实施例中，中空腔11内的渐缩形空腔结构14与圆台的渐缩形侧壁相适配连接，渐缩形的缩口结构提高了气溶胶生成装置的结构连接稳定性，进而提高了对第二连接端13的端面开口进行封堵的密封性。
如图2和图3所示，底面24连接有圆柱凸台25，圆柱凸台25的直径大于底面24的直径，圆柱凸台25抵接在第二连接端13的周向侧壁上。本实施例中，圆柱凸台25一方面增加了加热件2的结构强度，增加了加热件2的结构稳定性，进一步地提高了气溶胶生成装置的结构稳定性；另一方面， 圆柱凸台25的端面进一步地封堵住第二连接端13的端面开口，进而进一步地提高了提气溶胶发生基质段31区域的密封性。
如图2所示，第一连接端12内设置有依次相连通的第一空腔结构15、渐扩形空腔结构16及第二空腔结构17，第一空腔结构15位于渐缩形空腔结构14和渐扩形空腔结构16之间，渐扩形空腔结构16位于第一空腔结构15和第二空腔结构17之间，第一空腔结构15的内径小于气溶胶发生基质段31的外径，第二空腔结构17的内径大于气溶胶发生基质段31的外径。需要说明的是，第一空腔结构15、渐扩形空腔结构16及第二空腔结构17均为光滑内壁。本实施例中，具体地，第一空腔结构15可以为柱状空腔结构，第一空腔结构15的内径小于气溶胶发生基质段31的外径，第一空腔结构15与气溶胶发生基质段31之间为过盈配合，提高了气溶胶发生基质段31插入中空腔11内的结构稳定性，具体地，第二空腔结构17也可以为柱状空腔结构，第二空腔结构17的内径大于气溶胶发生基质段31的外径，提高了气溶胶发生基质段31从中空腔11内拔出的操作方便性；渐扩形空腔结构16使气溶胶发生基质段31较顺畅地在第一空腔结构15与第二空腔结构17之间移动，提高了气溶胶生成装置的结构稳定性及操作方便性。
如图2和图3所示，第二连接端13内还设置有第一过渡空腔结构18和第二过渡空腔结构19，第一过渡空腔结构18位于第二过渡空腔结构19和渐缩形空腔结构14之间，第二过渡空腔结构19位于第一过渡空腔结构18和第一空腔结构15之间，且第一过渡空腔结构18的内壁与加热体21的外壁相适配连接，第二过渡空腔结构19的内径大于加热体21的外径大小。需要说明的是，加热体21的形状可以为片状、针状或异性柱状，对应地，第一过渡空腔结构18和第二过渡空腔结构19均与加热体21相适配连接即可。本实施例中，具体地，第一过渡空腔结构18的内径小于加热体21的外径，当加热体21安装在中空腔11内时，加热体21的外壁紧密贴合在中空腔11内，提高了溶胶生成装置的结构稳定性；第二过渡空腔结构19的内径大于加热体21的外径大小，提高了加热体21从中空腔11内拔出的操作方便性。
如图2所示，提取件1包括可拆卸且密封连接的第一主体10和第二主体20，渐缩形空腔结构14设置在第一主体10内，第一空腔结构15、渐扩 形空腔结构16及第二空腔结构17均设置在第二主体20内，第一主体10的材质为柔性材料，第二主体20的材质为刚性材料。具体地，第一主体10与第二主体20之间可以通过啮合、胶粘、凹凸配合等方式进行密封连接。本实施例中，第一主体10为柔性材料，具体地，可以为硅胶，当加热件2插入中空腔11内时，第一主体10的内壁发生弹性变形，通过与圆台外侧壁之间的过盈配合实现圆台与第一主体10的密封连接，提高了气溶胶生成装置端面密封操作的方便性；第二主体20为刚性材料，气溶胶发生基质段31为柔性材料，两者之间也可以较好地通过过盈配合，实现气溶胶发生基质段31与中空腔11之间较适配的安装，提高了气溶胶发生基质段31区域的结构稳定性。
如图4所示，气溶胶生成装置还包括气溶胶介质3，气溶胶介质被配制成可与气溶胶生成装置配合使用的独立的且可替换的整体，气溶胶介质3包括端面依次抵接的气溶胶发生基质段31、气溶胶提取段32和功能滤嘴33，气溶胶提取段32位于气溶胶发生基质段31和功能滤嘴33之间，气溶胶发生基质段31的外侧壁密封贴合在第一连接端12内的内壁上，气溶胶提取段32位于第一连接端12外。本实施例中，具体地，气溶胶介质3为圆柱状结构，可以为烟支或烟弹；气溶胶发生基质段31、气溶胶提取段32和功能滤嘴33可同轴设置。当消费者抽吸气溶胶介质3时，气溶胶气体沿着朝向消费者口腔的一端扩散，进而使外面空气无法从靠近消费者口腔的一端进入到气溶胶发生基质段31内，从而进一步地实现对气溶胶发生基质段31区域进行封闭，提高了气溶胶发生基质段31区域的密封性，降低了气溶胶发生基质段31区域的氧气含量，进而降低了消费者在抽吸烟草制品时有害物质的生成；功能滤嘴能够有效地过滤掉气溶胶气体中的有害物质，减少了气溶胶对消费者的健康损害。
如图1和图4所示，气溶胶提取段32内设置有贯穿气溶胶提取段32长度方向的空腔35，且气溶胶提取段32的外侧壁上开设有至少一个与空腔35相连通的通孔34，通孔34沿垂直于气溶胶提取段32的长度方向贯穿气溶胶提取段32。本实施例中，通孔34可以为多个，多个通孔34沿气溶胶提取段32的外侧壁周向排列。上述通孔34作为气流通道，可有效提取气溶胶发生 基质段31受热产生的气溶胶，同时降低了消费者抽吸时的空气阻力，提高了消费者的体验舒适度。
