进一步参见图2和图3所示，感受器30是内部具有保持腔310的销钉或针状的形状；并且感受器30靠近开口50的前端为自由端、并通常被构造呈锥形尖端的形状便于插入至气溶胶生成制品A内，末端由保持腔310形成的敞口构造，便于在其内部装配感应线圈40；
感应线圈40，用于在交变电流下产生磁场；具体在结构上是沿感受器30的轴向延伸的螺旋形状。
在图3所示的实施中，感应线圈40是被完全装配和保持在感受器30的保持腔310内的，并且在装配后感应线圈40与感受器30彼此导热的。当然，感应线圈40与感受器30之间是彼此绝缘的；在可选实施中感应线圈40通过表面喷涂的绝缘层、或者包漆等方式形成绝缘的；或者感应线圈40与感受器30之间通过打胶、表面氧化、喷绝缘层等方式使它们接触的表面之间形成绝缘。
在实施中，采用感受性的金属或合金材质制备的感受器30，形成了对感应线圈40的磁场屏蔽器；感受器30基本能完全将感应线圈40产生的磁场吸收和屏蔽在内部，对于阻止气雾生成装置向外产生漏磁是有利的。作为另一实施，感受器30包括具有中空的细长状的基体和结合于基体上的感受发热部分，例如基体包括陶瓷材料，感受发热部分是结合在陶瓷基体的外表面或者内壁表面上的金属或合金材料层，或者是嵌入到陶瓷基体内的金属或合金材料，感应线圈收容在陶瓷基体的中空内部。作为可选实施，陶瓷基体可提供感应线圈与感受发热部分之间的绝缘。

在该实施例中，第一感受体31和第二感受体33能通过在感应线圈40的内部和外部发热；进而在使用中，能使加热器30在感应线圈40内部的中空内由第二感受体33保持热量；进而有助于保持加热器30的热容，对于阻止在抽吸中气流流过加热器30表面时使加热器30温度跳跃变化是有利的。
在该实施中，第一感受体31和第二感受体33均是由感受性的材质制备；例如良好的软磁材料或半硬磁材料，例如坡莫合金、不锈钢、FeAl合金等。
在该实施中，第一感受体31一方面通过自身的感应发热直接对气溶胶生成制品A进行加热，另一方面还能接收第二感受体33传递的热量转而对气溶胶生成制品A进行加热。
同样地，在一些实施中第二感受体33的外径基本是与感应线圈40的内径相同或接近的，进而基本是填满感应线圈40的内部空间；对于阻止在感应线圈 40内部的磁场向外产生漏磁是有利的。

在一个优选的实施中，细长的第二感受体基体331具有大约具有10～15mm的延伸长度；细长的第二感受体基体331大约具有低于1.5mm的外径。
根据图中所示，第二感受体基座332是与第一感受体31的保持腔310的内壁接触，进而彼此导热的。进而使第二感受体33在发热时的热量能直接通过与第一感受体31接触的方式传递至第一感受体31。
在一些其他的变化实施中，第二感受体33可以是通过感应线圈40进而与第一感受体31间接进行热量传递的。即，感应线圈40是同时与第一感受体31和第二感受体33导热的。
在又一些变化的实施中，感应线圈40的材质优选采用具有适当正向或负向电阻温度系数的材料制备，例如镍铝合金、镍硅合金、含钯合金、含铂合金等。在使用中，可以通过检测感应线圈40的电阻进而确定加热器30的温度。
或者在又一个变化的实施中，第一导电引脚41和第二导电引脚42分别采用不同的电偶丝材质，进而在它们之间可以形成用于检测感应线圈40/加热器30温度的热电偶。例如，第一导电引脚41和第二导电引脚42分别采用镍、镍铬合金、镍硅合金、镍铬-考铜、康青铜、铁铬合金等电偶材料中的两种不同材质制备的。
或者在其他的可选实施中，还可以通过在第一感受体31的保持腔310内部填装用于感测加热器30温度的传感器，例如常用的PTC温度传感器等，或者又例如在第一感受体31的保持腔310的内壁上焊接至少两个不同材质的电偶丝，进而在它们之间形成可用于检测加热器30温度的热电偶，可以理解上述传感器不限于热电偶。
进一步在图14或图15所示优选的实施中，装置还包括：
基座或法兰34；在图中该基座或法兰34是PEEK、陶瓷例如ZrO 2和Al 2O 3陶瓷等耐热材料。在制备上，将基座或法兰34通过高温粘胶粘接、模制例如模内注塑、或者是焊接等方式固定在第一感受体31的下端并保持固定连接；进而气雾生成装置可以通过支撑、夹持或保持等方式对基座或法兰34对加热器30进行稳定安装和保持。
进一步根据图14和图15所示的优选实施，基座或法兰34呈环形的形状，并具有中孔341；当基座或法兰34与加热器30下端装配后，第一导电引脚41和第二导电引脚42由基座或法兰34的中孔341贯穿出来，进而便于与电路20连接。
同时根据图15所示的优选实施，基座或法兰34的中孔341的内径小于第二感受体33的第二感受体基座332的外径，对于通过支撑第二感受体33进而使其固定和保持在第一感受体31内是有利的。
进一步图17示出了又一个优选实施，包括有：
销钉或针状的第一感受体31b，第一感受体31b内的保持腔310b用于容纳和封装感应线圈40a；
第二感受体33b，包括呈细长杆状的第二感受体基体331b、以及第二感受体基座332b；第二感受体基座332b与第二感受体基体331b结合的部位形成有台阶333b。
感应线圈40a用于产生变化的磁场；第一感受体31b和第二感受体33b被变化的磁场穿透而发热；第一感受体31b部分可以直接感应发热以加热气溶胶生成制品A、另一部分还能通过接收第二感受体33b的热量转而加热气溶胶生成制品A。
在装配中第二感受体33b的第二感受体基体331b由感应线圈40a的上端贯穿至感应线圈40a的下端；第二感受体33b通过台阶333b抵靠在感应线圈40a的上端形成止动。同时，感应线圈40a的第一导电引脚41a和第二导电引脚42a由基座或法兰34b的中孔341b贯穿至第一感受体31b外，进而与便于电路20连接。
在该实施中，第二感受体33b的第二感受体基座332b大体是呈锥形，并通过该锥形的第二感受体基座332b与第一感受体31b的保持腔310b的锥形顶端配合装配固定、或接触形成相互导热。
当然在该实施中，第二感受体33b的第二感受体基体331b沿感应线圈40a的轴向的延伸长度大于或等于感应线圈40a的轴向延伸长度。
本申请的又一个实施例中，以上第一感受体31/31b、感应线圈40/40a与第二感受体33/33b之间是彼此绝缘的。在一个优选的实施中，它们之间是通过填充的耐高温绝缘胶例如环氧树脂胶进行绝缘；具体在装配的过程中，将感应线圈40/40a和第二感受体33/33b表面浸涂/刷涂耐高温绝缘胶后，将它们装配至第一感受体31/31b内，而后通过加热使耐高温绝缘胶固化即可。在一个可选的实施中，通过热风枪对准第一感受体31/31b的保持腔310/310b吹热风，使耐高温绝缘胶加热固化。或者在又一个可选的实施中，通过对感应线圈40/40a供电使其发热进而使耐高温绝缘胶固化，例如刚开始以较小功率加热一段时间，然后逐渐增大到4W左右，直到第一感受体31/31b内部的耐高温绝缘胶完全固化为止。
通常在实施中，以上第一感受体31/31b可以是由单一的感受性材质制备。作为又一个变化的实施例，以上第一感受体31/31b是由具有保持腔310的细长状的基体和结合于基体上的感受性材料的涂层，例如基体包括陶瓷材料、石英灯，感受性材料的涂层是结合在陶瓷基体或石英基体的外表面或者内壁表面上的感受性的金属或合金材料层(例如涂层)制备获得。在该可选实施，陶瓷基体可提供第一感受体31/31b与感应线圈40/40a之间的绝缘。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
