基座25大致呈管状，其内部的中空部分界定或者形成至少部分接收腔C。装配后，底座16的第二连接部分162至少部分被接收在接收腔C内。在底座16的第二连接部分162被接收在接收腔C内时，第一连接部分161与基座25是保持接触的，而第二连接部分162的底表面与接收腔C的底壁之间是保持接触的或者间隙非常小可以忽略。
感应线圈26在交变电流下产生变化的磁场，电芯23将高频振荡电流提供给感应线圈26。供应到感应线圈26的交变电流的频率介于500KHz～3MHz；优选的，所述频率可以介于500KHz～2.5MHz；进一步优选的，所述频率可以介于500KHz～2MHz；进一步优选的，所述频率可以介于500KHz～1.5MHz；进一步优选的，所述频率可以介于500KHz～1MHz。
如图8所示，感应线圈26的主体部分26a被构造成围绕中心轴线S2螺旋卷绕的管状感应线圈。主体部分26a套设或者环绕在基座25外围，即周向或者环绕地布置在接收腔C的周围。主体部分26a可以具有椭圆形、圆形、正方形、矩形、三角形或其它多边形的横截面。例如，对于圆形横截面的主体部分26a，中心轴线S2为主体部分26a顶端的圆形横截面的中心与底端圆形横截面的中心之间的连线；其它形状与此类似。感应线圈26的电连接部26b、电连接部26c用于与电芯23电连接。
主体部分26a是由较长的导线材料绕制而成，例如：采用500～2000根导线卷绕成型，或者采用500～1900根导线，或者采用700～1900根导线，或者采用900～1900根导线，或者采用1000～1900根导线，或者采用1200～1900根导线，或者采用1400～1900根导线，或者采用1600～1900根导线。导线材料的截面可以是矩形、圆形或者椭圆形。
主体部分26a的匝数或者绕组介于4匝～20匝；优选的，介于6匝～20匝；进一步优选的，介于6匝～15匝；进一步优选的，介于6匝～12匝；进一步优选的，介于6匝～10匝。相邻匝数或者绕组之间的间距大约为0.1～0.5mm；在一个具体的实施例中，相邻匝数或者绕组之间的间距为0.2或者0.4mm。
基于感受器141的设计或者电子雾化装置100的整体设计等因素，感受器141沿中心轴线S1的轴向跨距d1通常为第二连接部分162的轴向跨距的 三分之一以下(大致在四分之一至三分之一之间)。为了在底座16的第二连接部分162被接收在接收腔C内时，使得感受器141能够被完全置入在感应线圈26内，感应线圈26沿中心轴线S2的轴向跨距d11大于感受器141沿中心轴线S1的轴向跨距d1，且感应线圈26沿中心轴线S2的轴向跨距d11为接收腔C沿中心轴线S2的轴向跨距d12的三分之二以上，最大可与d12相同。这样，感受器141能够被完全置入在感应线圈26内，由感应线圈26产生的交变磁场到感受器141的耦合显著增加。图9示出了感受器141被完全置入在感应线圈26内的情形。感受器141被完全置入在感应线圈26内，意味着感受器141的上下两端与感应线圈26的上下两端均是对应的保持间隔的。
在一示例中，感应线圈26沿中心轴线S2的轴向跨距d11可以为感受器141沿中心轴线S1的轴向跨距d1的二倍以上。优选的，介于2～3倍之间。
在一示例中，感应线圈26沿中心轴线S2的轴向跨距d11介于10mm～15mm；优选的，介于10mm～14mm；进一步优选的，介于10mm～13mm；进一步优选的，介于11mm～13mm。
进一步的实施中，感受器141的中心轴线S1与感应线圈26的中心轴线S2之间的偏移距离介于0～3mm(包括端点值)。感受器141沿中心轴线S1的轴向跨距的中点K1，与感应线圈26沿中心轴线S2的轴向跨距的中点K2之间的偏移距离介于0～3mm(包括端点值)。在感受器141的中心轴线S1与感应线圈26的中心轴线S2之间的偏移距离为0mm时，意味着中心轴线S1与中心轴线S2重合；在感受器141沿中心轴线S1的轴向跨距的中点K1与感应线圈26沿中心轴线S2的轴向跨距的中点K2之间的距离为0mm时，意味着感受器141的中心与感应线圈26的中心重合、或者轴向方向的中心重合。图10-图11示出了这2种都重合的情形。
这是有利的，感应线圈26产生的交变磁场在其中心处是最强的，而在其两端处是较弱的；因此，中心轴线S1与中心轴线S2重合、且感受器141的中心与感应线圈26的中心重合，意味着由感应线圈26产生的交变磁场到感受器141的耦合达到最佳，感应线圈26与感受器141构成的感应加热组件的转化效率达到最佳。
发明人对中心轴线S1与中心轴线S2之间的距离(对应以下表格中的D2)、感受器141沿中心轴线S1的轴向跨距的中点K1与感应线圈26沿中心轴线 S2的轴向跨距的中点K2之间的距离(对应以下表格中的D1)进行测试，测试结果如下：
以上测试结果能够表明：中心轴线S1与中心轴线S2重合、且感受器141的中心与感应线圈26的中心重合，感应加热组件的转化效率达到最佳，约为85.34％；中心轴线S1与中心轴线S2之间的距离增大、或者感受器141沿中心轴线S1的轴向跨距的中点K1与感应线圈26沿中心轴线S2的轴向跨距的中点K2之间的距离增大时，感应加热组件的转化效率均呈下降趋势；相对感受器141沿中心轴线S1的轴向跨距的中点K1与感应线圈26沿中心轴线S2的轴向跨距的中点K2之间的距离变化，中心轴线S1与中心轴线S2之间的距离变化对感应加热组件的转化效率影响较大。
请再参考图4-图5、图7所示，与前述类似的，感受器141沿中心轴线S1的轴向跨距的中点K1与第二连接部分162的底端表面之间的距离为d2，感应线圈26沿中心轴线S2的轴向跨距的中点K2与接收腔C的底壁之间的距离为d13，d2与d13之间的差值介于0～3mm。中心轴线S1与第二连接部分162的外表面之间的距离为d3，中心轴线S2与接收腔C的内壁之间的距离为d14，d3与d14之间的差值介于0～3mm。
进一步的实施中，感应线圈26与感受器141之间的最小径向距离d15介于3～7mm；优选的，介于3～6mm；进一步优选的，介于4～6mm。确保由感应线圈26产生的交变磁场到感受器141的耦合。
屏蔽件27环绕设置或套设在感应线圈26外。屏蔽件27用于屏蔽感应线圈26大致沿着径向方向散发的磁场，以避免该散发的磁场影响其它部件。
传感器28通过感应通道感应下壳体21内的气流变化，即检测用户的抽吸，以生成信号控制雾化器10启动工作。
