本实施例中，如图6和图7所示，发热顶座1441的顶壁1441b靠近发热底座1442的表面具有卡接部1441e，密封件145靠近发热顶座1441的顶壁1441b的表面具有卡接槽1452，卡接部1441e与卡接槽1452卡接。卡接部1441e与固定座142夹持卡接槽1452的底壁，也可以是卡接部1441e与发热底座1442夹持卡接槽1452的底壁，通过设置卡接部1441e和卡接槽1452，能使发热顶座1441对密封件145进行进一步地固定和限位。
在其他实施例中，也可以是发热顶座1441的顶壁1441b靠近发热底座1442的表面具有卡接槽1452，密封件145靠近发热顶座1441的顶壁1441b的表面具有卡接部1441e，卡接槽1452与卡接部1441e卡接。卡接槽1452与卡接部1441e的形状不限，可以根据需要设计，只要发热底座1442和密封件145中的一个具有卡接部1441e，另一个具有卡接槽1452即可。发热座组件144与密封件145之间的设置方式不限于本申请提到的几种结构，也可以是其他的结构。
进一步地，卡接部1441e靠近固定座142的一端具有凸起部1441f，密封件145的卡接槽1452的底壁上具有通孔1453，通孔1453与凸起部1441f对应设置。凸起部1441f设置于通孔1453中，通过凸起部1441f和通孔1453的配合，可以对密封件145进一步的固定和限位。在一种实施例中，通孔1453与凸起部1441f过盈配合，以阻隔液体沿发热顶座1441的凸起部1441f渗漏，以增加发热体组件14的密封效果。
凸起部1441f和通孔1453的数量可以相同，并且，凸起部1441f和通孔1453的数量可以是一个或者多个，本实施例中，凸起部1441f和通孔1453的数量均为三个。凸起部1441f和通孔1453的数量越多，对密封件145的固定效果越好。 在其他实施例中，通孔1453也可以为盲孔，不仅可以固定和限位，且不会漏液。
在一种实施例中，如图6和图8所示，图8为本申请一实施例提供的发热底座的结构示意图。发热底座1442具有限位槽1442a，固定座142设置于限位槽1442a中。限位槽1442a的形状可以与固定座142的形状相同，以使固定座142设置于限位槽1442a中，限位槽1442a能对固定座142进行固定和限位。通过将固定座142设置于限位槽1442a中，一方面，可以实现发热体141的固定，另一方面，可以使得固定座142的轴线与发热座组件144的轴线平行，在发热体141与固定座142垂直的情况下，进而使得发热体141的轴线与发热座组件144的轴线平行，通过调整发热座组件144与第一安装座12以及第二安装座13的轴线平行，能使得发热体141的轴线与加热腔131的轴线平行或者重合。从而，发热体141能均匀地对加热腔131中的气溶胶产生基质20加热。
本实施例中，发热顶座1441的凸起部1441f也可以穿过通孔1453，并且与固定座142靠近连接部1413的一面抵接，以使凸起部1441f与限位槽1442a共同配合对固定座142的四周进行限位，从而实现了发热体141的固定。在其他实施例中，发热座组件144对固定座142的固定方式也可以是其他的方式，不限于本申请提到的固定方式。
在一种实施方式中，如图9所示，图9为本申请另一实施例提供的发热体组件的剖视结构示意图。在该实施例中，固定座142套设在基体1411的第一端1411a，基体1411的第一端1411a的端部穿过固定座142设置于固定座142远离基体1411的第二端1411b的一侧。发热底座1442上的限位槽1442a的底壁上具有限位孔1442b，基体1411位于固定座142远离基体1411的第二端1411b的部分设置于限位孔1442b中，并且，限位孔1442b与基体1411过盈配合。在该实施例中，发热顶座1441的第二安装孔1441d也与基体1411过盈配合。发热顶座1441的第二安装孔1441d以及发热底座1442的限位孔1442b均与基体1411过盈配合，从而可以通过第二安装孔1441d和限位孔1442b直接实现基体1411的固定，并且，通过使第二安装孔1441d和限位孔1442b的轴线重合，可以直接实现发热座组件144的轴线与发热体141的轴线重合，从而实现发热体141与加热腔131的轴线重合，以使发热体141能均匀的对气溶胶产生基质20的四周加热。这种通过发热座组件144对发热体141直接固定的方式，降低了固定 座142与发热体141的垂直度的要求，并且对固定座142的形状的要求降低，对固定座142的制造精度要求降低，从而减小了发热体组件14的制造难度。
以上仅为本申请的实施方式，并非因此限制本申请的专利范围，凡是利用本申请说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本申请的专利保护范围内。
