密封件12设置在传输管11a与上支架13之间、底座16与上壳体11之间，以对传输管11a与上支架13之间、底座16与上壳体11之间的间隙进行密封。在另一示例中，密封件12可以包括多个分体的密封件，例如，设置在传输管11a与上支架13之间的一个密封件，设置在底座16与上壳体11之间的另一个密封件。在另一示例中，密封件12与底座16(或者上壳体11)一体形成也是可行的，例如：通过双色注塑一体形成。在另一示例中，不设置密封件12也是可行的。
进一步的实施中，密封件12内、和/或密封件12与传输管11a之间、和/或密封件12与上壳体11之间、和/或传输管11a与上支架13之间、和/或底座16与上壳体11之间，可以设置气压平衡通道，以向储液腔A补充气体进而使得储液腔A内外气压平衡，利于液体基质的传递。
上支架13大致呈管状。上支架13的上端朝向第一部分161延伸、且与传输管11a连接，上支架13的下端被收容在底座16的第二部分162内。上支架13的内部中空部分界定部分气流通道。上支架13中间部分的内径或者外径较其它部分的内径或者外径小。
进一步的实施中，上支架13靠近上端的外表面具有朝外径向延伸的定位部13b，底座16的第一部分161内具有凹槽161c。装配时，定位部13b需要对准凹槽161c，以使得定位部13b至少部分卡接在凹槽161c内，从而固定或者保持上支架13的上端。
进一步的实施中，在底座16的第二部分162内设置有支撑部162b，上支架13下端的端部与支撑部162b抵接。优选的实施中，支撑部162b包括多个间隔设置的凸块，该多个间隔设置的凸块凸出于第二部分162的内侧壁或者底壁；这样，液体基质或者冷凝后的液体基质可沿着该凸块之间的间隙流入收集腔162c。

雾化芯14包括感受器141。感受器141配置为与磁场发生器26感应耦合，在被变化磁场穿透下发热，进而对液体基质进行加热，以生成供吸食的气溶胶。感受器141可选用以下至少之一材料制成：铝、铁、镍、铜、青铜、钴、普通碳钢、不锈钢、铁素体不锈钢、马氏体不锈钢或奥氏体不锈钢。

优选的实施中，液体传递单元142采用多孔陶瓷，多孔陶瓷的材质 包括氧化铝、氧化锆、高岭土、硅藻土、蒙脱石中的至少一种。多孔陶瓷的孔隙率可以在10％～90％范围内调整，平均孔径可以在10μm～150μm范围内调整。在一些实施中，所述调整例如可以通过造孔剂添加量和造孔剂粒度选择进行。
在该优选的实施中，液体传递单元142被构造成内部中空的管状；可以是圆管状或者方管状，优选的采用圆管状。液体传递单元142还包括间隔部142a，间隔部142a纵向延伸布置。间隔部142a的壁厚(厚度尺寸)介于0.1mm～1mm；优选的，介于0.2mm～1mm；优选的，介于0.4mm～1mm；优选的，介于0.4mm～0.8mm；优选的，介于0.4mm～0.6mm；具体示例中，间隔部142a的壁厚为0.5mm。
间隔部142a的纵向延伸长度(纵向尺寸)与液体传递单元142相同。间隔部142a将液体传递单元142内部的中空分隔成第一腔室142b和第二腔室142c，这样利于保持液体传递单元142的强度，减小液体传递单元142的体积，提升雾化芯14的加热效率。第一腔室142b和第二腔室142c在大体上平坦的相对端面之间纵向延伸。第一腔室142b的横截面面积大于第二腔室142c的横截面面积。第一腔室142b的横截面为半圆形。
感受器141呈片状或者板状。感受器141的纵向延伸方向与液体传递单元142的中心轴平行或者重合。感受器141的纵向尺寸大于感受器141的横向尺寸。感受器141布置液体传递单元142内且感受器141的至少部分表面是与液体传递单元142接触的。具体地，感受器141布置在第一腔室142b内，且感受器141与间隔部142a的侧壁保持接触或者部分感受器141埋设在间隔部142a内(另一部分感受器141裸露在间隔部142a外)。感受器141保持在间隔部142a的侧壁上，感受器141的厚度尺寸小于间隔部142a的厚度尺寸。感受器141的横向尺寸与横截面为半圆形的第一腔室142b的直径(即为液体传递单元142的内径)相同；一般的其横向尺寸介于1mm～4mm；优选的介于1mm～3mm；优选的介于1mm～2.5mm；优选的介于1.5mm～2.5mm；优选的介于2mm～2.5mm。感受器141的纵向尺寸与液体传递单元142的纵向尺寸相同；一般的其纵向尺寸介于4mm～8mm；优选的介于4mm～7mm；优选的介于4mm～6mm。感受器141的厚度可尽量小，一般的其厚度介于0.05mm～0.5mm；优选的介于0.05mm～0.2mm；优选的介于0.05mm～0.15mm；优选的介于0.08mm～0.15mm。感受器141沿厚度方向具有多个间隔设置的通孔141a，孔径为0.1mm～0.5mm，形状可以是圆形、椭圆形、三角形、菱形、其它规则或者不规则形状。这样，一方面减小感受器141的体积，另一方面可使得感受器 141的雾化面积最大化，进一步提升雾化芯14的加热效率。
间隔部142a中与感受器141保持接触的侧壁界定或者形成雾化芯14的雾化面，液体传递单元142的外侧壁或者外表面界定或者形成吸取液体基质的吸液面；这样，吸取的液体基质传递至感受器141时被加热生成气溶胶，生成的气溶胶流入第一腔室142b内，与从第一腔室142b底部流入的空气一起流出第一腔室142b外。通过间隔部142a，液体传递单元142可及时的将液体基质传递至感受器141，避免感受器141干烧等现象。由于感受器141的热量可传导至间隔部142a的另一侧壁，该另一侧壁的液体基质同样可被加热生成气溶胶，生成的气溶胶流入第二腔室142c内，与从第二腔室142c底部流入的空气一起流出第二腔室142c外。这样，液体传递单元142内部的中空形成气流通道，外部空气可从液体传递单元142的一端流入并从液体传递单元142的另一端流出。
需要说明的是，在其它示例中，不设置间隔部142a，也是可行的。此时，液体传递单元142的横截面呈圆环状。感受器141两端(横向方向)的端部可嵌入或者埋设于液体传递单元142内。即感受器141的横向尺寸大于液体传递单元142的内径且小于液体传递单元142的外径。需要说明的是，在此示例中，感受器141可采用既可导液又可在变化的磁场中发热的材料制成。
需要说明的是，在其它示例中，不设置第二腔室142c或者说只有第一腔室142b，也是可行的。但相对的，液体传递单元142的体积较大。
需要说明的是，在其它示例中，由于感受器141的厚度尺寸较小，感受器141还可完全埋设于间隔部142a内(此时感受器141也可视为布置液体传递单元142内)，也是可行的。此时，第一腔室142b的横截面面积与第二腔室142c的横截面面积可以相同。
还需要说明的是，在其它示例中，还可由感受器141形成至少部分间隔部142a，通过感受器141将液体传递单元142内部的中空分隔成两个第一腔室142b和第二腔室142c。此时，第一腔室142b的横截面面积与第二腔室142c的横截面面积也可以相同。

第二部分162裸露在上壳体11或者雾化器10外。第二部分162的厚度方向尺寸小于第一部分161的厚度方向尺寸、第二部分162的宽度方向尺寸小于第一部分161的宽度方向尺寸(或者，第一部分161的横截面面积大于第二部分162的横截面面积)，而第二部分162的长度(或者纵向)方向尺寸要大于第一部分161的长度方向尺寸。

第二部分162的底端设置有进气口162a，形成进气口162a的壁凸出于第二部分162的底端，以避免收集腔162c收集的液体基质直接通过该进气口162a流向电源组件20。外部空气通过进气口162a流入，依次经过管状结构的液体传递单元142(和/或感受器141)、上支架13、传输管11a后，从上壳体11的出气口流出，从而界定或者形成电子雾化装置100气流通道。

磁场发生器26在交变电流下产生变化的磁场，磁场发生器26包括但不限于感应线圈。磁场发生器26靠近接收部C设置。磁场发生器26至少部分围绕接收部C。磁场发生器26的主体部分26a套设在基座25的主体部分25a外。磁场发生器26的电连接部26b、电连接部26c用于与电芯23电连接。底座16的第二部分162至少部分被接收在接收部C内时，雾化芯14或者感受器141是完全位于接收部C内的，从而磁场发生器26产生的磁场能够基本上覆盖感受器141；这样，减少了感受器141与磁场发生器26的耦合距离，能够提升雾化器10的加热效率。优选的实施中，底座16的第二部分162至少部分被接收在接收部C内时，感受器141与磁场发生器26是同轴的，均沿着电子雾化装置100的轴向方向延伸。磁场发生器26沿轴向方向的延伸长度大于感受器141沿轴向方向的延伸长度。
如图13-图14所示，磁场发生器26的主体部分26a是由较长的导线材料绕制的螺线管线圈，例如：采用1600～1900根0.02mm利兹线卷绕成型，也可采用750～1050根0.03mm利兹线卷绕成型。螺线管线圈的匝数或者绕组介于6匝～20匝；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。相邻绕组之间的间距大约为0.1～0.5mm；相邻绕组之间的间距可以相同，也可以不同。
导线材料的截面具有沿磁场发生器26的径向方向X延伸的第一边，以及沿磁场发生器26的轴向方向Y延伸的第二边。导线材料的截面大致呈矩形状，第一边的尺寸L大于第二边的尺寸H，进而使得磁场发生器26的导线材料是扁平构造，对于在单位长度上提升磁场发生器26的匝数进而提升电感值是有利的。另外，第二边贴靠接收部C的壁布置，即贴靠基座25的主体部分25a的外表面布置，也可在有限的高度空间内提升磁场发生器26的匝数。
优选的实施中，第一边的尺寸L与第二边的尺寸H的比值介于1.5～3；优选的，介于2～3；进一步优选的，介于2.5～3。例如一个具体的实施例中，第一边的尺寸L与第二边的尺寸H的比值为2.8。
优选的实施中，第一边的尺寸L大约为1～5mm；第二边的尺寸H大约为0.3～1mm。例如一个具体的实施例中，第一边的尺寸L为2.5mm；第二边的尺寸H为0.9mm。
优选的实施中，磁场发生器26的主体部分26a沿轴向方向Y的总长度大约为5～20mm；在一个具体的实施例中，磁场发生器26的主体部分26a沿轴向方向Y的总长度为12.2mm。
优选的实施中，主体部分26a的中空部分呈椭圆形，椭圆形的长轴与短轴的差值介于0.5mm～2mm。具体地，该椭圆形的长轴R1的长度介于8mm～15mm(优选的，介于8mm～12mm；进一步优选的，介于8mm～10mm；进一步优选的，介于9mm～10mm)；该椭圆形的短轴R2的长度介于8mm～13mm(优选的，介于8mm～11mm；进一步优选的，介于8mm～10mm；进一步优选的，介于8mm～9mm)。在一个具体的实施例中，椭圆形的长轴R1的长度为9.7mm，椭圆形的短轴R2的长度为8.9mm。
屏蔽件27套设在磁场发生器26的主体部分26a外。屏蔽件27用于屏蔽磁场发生器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223c感应凹槽223a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。
