外筒31套接在内筒32上，且包括管状的本体31a、自本体31a朝 向远离本体31a方向延伸的延伸部31b，延伸部31b大致呈半管状。与外筒31类似的，内筒32也包括管状的本体312a、延伸部32b。外筒31具有卡孔31a1、收容槽31a2以及端部31a3，磁性件33收容在收容槽31a2中。
在隔热组件30插接在电源组件60时，内筒32的延伸部32b紧贴着支架63的侧壁往下移动且固定在插槽63g中，外筒31的延伸部31b抵接在插槽63g的边缘。进一步地，卡孔31a1与凸扣63i相配合，以将外筒31与支架63卡扣连接。
提取器20用于提取接收于加热腔室A的气溶胶生成制品200。提取器20被构造成沿加热腔室A的轴向延伸的管状，管状的中空部分形成加热腔室A。在提取器20未提取气溶胶生成制品200时，其一端伸入到内筒32内，另一端保持在外筒31的端部31a3上。提取器20的外壁设置有腔室，以收容磁性件21；这样，通过磁性件21与磁性件33的配合，利于将提取器20保持在外筒31上。
上盖10套接在隔热组件30和提取器20上，上盖10与提取器20的端部抵接。上盖10与电源组件60的壳体61齐平，保持外观整洁一致。上盖10还具有开口，气溶胶生成制品200通过该开口可移除地接收在加热腔室A中。
请结合图6-图7进行理解，加热组件40包括加热器41、基座42以及固定座43。
加热器41用于加热接收在加热腔室A中的气溶胶生成制品200，以生成可吸食的气溶胶。加热器41可被构造成针状或者片状，其近端可穿过提取器20的一端(提取器20伸入到内筒32内的一端设置有通孔)、并插入接收于加热腔室A的气溶胶生成制品200中。加热器41的远端保持在基座42中，固定座43用于保持基座42。加热器41与基座42可以一体形成，也可以分体形成。
在图6-图7的示例中，加热器41包括电阻加热元件(未示出)，以与电芯62藕接而发热。加热器41与基座42分体形成，基座42大致呈柱状、且具有通孔。加热器41的远端保持在基座42的通孔中，可通过焊接、打胶等方式固定。
固定座43包括座体43a、自座体43a的第一敞口端朝向气溶胶生成装置100外径向延伸的第二延伸部43b。座体43a具有第一敞口端、与所述第一敞口端相对的第二敞口端、以及自所述第一敞口端延伸至所述第二敞口端的收容室43c；基座42至少部分被收容在收容室43c中。收容室43c与基座42的形状相匹配。
座体43a的内壁上具有多个间隔设置的凸棱43d；这样，在基座42被收容在收容室43c中时，凸棱43d与基座42抵接，从而使得基座42与固定座43之间至少部分保持一定的间隙。基座42的外壁、座体的内壁大致由4个面组成，凸棱43d与基座42的接触面积要小于基座42外壁中一个面的表面积；优选的，凸棱43d与基座42的接触面积小于一个面的表面积的二分之一；进一步优选的，凸棱43d与基座42的接触面积小于一个面的表面积的四分之一；进一步优选的，凸棱43d与基座42的接触面积小于一个面的表面积的六分之一；进一步优选的，凸棱43d与基座42的接触面积小于一个面的表面积的八分之一；进一步优选的，凸棱43d与基座42的接触面积小于一个面的表面积的十六分之一。这样，通过设置的凸棱43d，减少了基座42与固定座43的接触面积，避免加热器41的热量损失。
可以理解的，直接在基座42与固定座43之间设置类似于凸棱43d的第一间隔件，或者，在基座的外壁上设置多个上述凸棱43d，使得基座42与固定座43之间至少部分保持一定的间隙，也是可行的。
还可以理解的，固定座43被构造成围绕至少部分基座42也是可行的；此时，第一间隔件与基座42的接触面积小于基座42外壁的表面积或者基座42外壁中任意一个面的表面积；或者，第一间隔件与固定座43的接触面积小于固定座43内壁的表面积或者固定座43内壁中任意一个面的表面积。
优选的实施中，间隙介于0.1mm～0.3mm；进一步优选的，间隙介于0.15mm～0.3mm；进一步优选的，间隙介于0.2mm～0.3mm；进一步优选的，间隙介于0.25mm～0.3mm。
固定座43还包括自所述第二敞口端径向延伸的第一延伸部43e；这样，在基座42被收容在收容室43c中时，基座42可保持在第一延伸部43e上。进一步地，第一延伸部43e上具有朝向所述第一敞口端延伸的第一凸块43f，从而使得基座42与第一延伸部43e之间至少部分保持一定的间隙。与前述类似的，可以在基座42与第一延伸部43e之间设置类似于第一凸块43f的第二间隔件，使得基座42与第一延伸部43e之间至少部分保持一定的间隙，也是可行的。
在隔热组件30插接在电源组件60时，第二延伸部43b保持在支架63的端部上。第二延伸部43b与支架63的端部可以直接抵接，并通过打胶进行密封处理。优选的实施中，支架63的端部间隔设置有多个朝向第二延伸部43b凸出的第二凸块63j，第二延伸部43b与第二凸块63j抵接，利于减少第二延伸部43b与支架63的接触面积，避免加热器41 的热量损失，同时防止壳体61的温度过高。
在第二延伸部43b保持在支架63的端部上时，隔热腔室63a至少部分围绕座体43a；隔热腔室63a的设置可减少热量传递到支架63，防止壳体61的温度过高。可以理解的，隔热腔室63a可密封空气、设置隔热材料、抽真空等方式进行隔热。
图10本申请第二实施方式提供的固定座的剖面示意图。
固定座430包括座体430a、第二延伸部430b、收容室430c、凸棱430d、第一延伸部430e，这些部件与图7示例的类似，具体的可参考前述内容，在此不作赘述。
与图7不同的是，固定座430还包括自第二延伸部430b朝向加热器的近端轴向延伸的第三延伸部430g；第三延伸部430g可插入接收于加热腔室A的气溶胶生成制品200中，以将固定座430的热量传递给气溶胶生成制品200。第三延伸部430g可采用与其它部件不同的材质，优选的实施中，第三延伸部430g的导热系数大于座体430a和/或第二延伸部430b的导热系数，从而利于将固定座430的热量传递给气溶胶生成制品200。在其它示例中，第三延伸部430g可采用与其它部件相同的材质，固定座430还可包括设置在第三延伸部430g上的导热件(未示出)，所述导热件用于将固定座430的热量传递给气溶胶生成制品200。
图11-图16本申请第三实施方式提供的气溶胶生成装置及其部件示意图。
需要说明的是，大部分结构可参考图1-图9的示意图及其说明，以下针对与图1-图9的示例不同的地方进行说明：
在图11-图16的示例中，加热器410配置为被变化的磁场穿透而发热。
在图11-图16的示例中，第一间隔件包括形成在基座420的外壁上的第二凸棱420a，其优选的实施中，多个第二凸棱420a间隔设置；在基座420保持在固定座4300中时，第二凸棱420a与固定座4300抵接，使得基座420与固定座4300之间至少部分保持一定的间隙。
在图11-图16的示例中，基座420与固定座4300配置为卡扣连接；具体地，基座420的外壁上具有凸扣420b，固定座4300靠近第二敞口端的侧壁上具有与凸扣420b相配合的卡孔4300i。
在图11-图16的示例中，固定座4300包括自第二延伸部4300b朝向支架630轴向延伸的第四延伸部4300h；第二延伸部4300b通过第四延伸部4300h保持在支架的台阶630j上，台阶630j形成在隔热腔室630a中。优选的实施中，第四延伸部4300h可以为多个间隔设置的凸块，以 减少固定座4300与支架的接触面积。
在图11-图16的示例中，气溶胶生成装置还包括密封件440，密封件440设置在基座420与固定座4300之间。密封件440与加热器410之间的轴向距离小于第一间隔件与加热器410之间的轴向距离，即密封件440相对第二凸棱420a，更靠近加热器410的近端设置。
请参考图15所示，密封件440包括本体440a和偏置部440b。本体440a与偏置部440b一体形成。本体440a套接在基座420上。偏置部440b的一端设置在本体440a上，另一端偏离本体440a并与固定座4300抵接。这样，减少密封件440与固定座4300之间的接触面积，从而减少热量传递。
优选的实施中，密封件440的纵截面呈倒V形状。偏置部440b与本体440a之间的夹角θ小于90°；进一步优选的，偏置部440b与本体440a之间的夹角θ小于60°；进一步优选的，偏置部440b与本体440a之间的夹角θ小于45°。
需要说明的是，在其它示例中，密封件440可以为液体密封胶，通过液体密封胶实现基座420与固定座4300之间的密封也是可行的。
需要说明的是，本申请的说明书及其附图中给出了本申请的较佳的实施例，但是，本申请可以通过许多不同的形式来实现，并不限于本说明书所描述的实施例，这些实施例不作为对本申请内容的额外限制，提供这些实施例的目的是使对本申请的公开内容的理解更加透彻全面。并且，上述各技术特征继续相互组合，形成未在上面列举的各种实施例，均视为本申请说明书记载的范围；进一步地，对本领域普通技术人员来说，可以根据上述说明加以改进或变换，而所有这些改进和变换都应属于本申请所附权利要求的保护范围。
