参阅图1，本申请一实施例提供了一种电子雾化器，包括雾化组件100及电源组件，雾化组件100与电源组件(图未示)电性连接，雾化组件100在电源组件的电能作用下加热膏状、流体状或油状的气溶胶生成基质200，从而产生气溶胶供使用者吸食。在下列实施例中，气溶胶生成基质200呈膏状或油状。
具体地，雾化组件100包括主壳体120、线圈140以及发热体160。主壳体120具有一端开口的雾 化腔1236以容纳气溶胶生成基质200。线圈140绕设于雾化腔1236外并与电源组件电连接，线圈140可在电源组件提供的交变电压的作用下产生交变磁场。发热体160收容于雾化腔1236内，并能够悬浮于雾化腔1236内的气溶胶生成基质200中，发热体160能够感应线圈140产生的交变磁场以产生交变电流，发热体160上的电荷高速无规律运动，碰撞摩擦产生热能而加热气溶胶生成基质200。
如此，发热体160悬浮于气溶胶生成基质200而于气溶胶生成基质200充分接触，可以根据需要设置为较大的体积，从而有效减少预热时间，提升了能量利用率。而且，发热体160悬浮于气溶胶生成基质200中，发热体160的所有外表面与主壳体120均不存在直接接触，因此可有效防止发热体150产生的热量向主壳体120传递，进而有效降低了主壳体120的外表面的温度。
请参阅图1及图2，主壳体120包括外壳体121及内壳体123。外壳体121呈中空的筒状结构，包括外壳体底壁1212及自外壳体底壁1212的边缘沿同一方向延伸形成的外壳体侧壁1214，外壳体侧壁1214沿周向环绕外壳体底壁1212以形成一端开口的容纳腔，外壳体底壁1212开设有至少一个连通外界环境和容纳腔的外壳体进气孔1212a。
内壳体123呈中空的筒状结构，包括内壳体底壁1232及自内壳体底壁1232的边缘朝同一方向延伸形成的内壳体侧壁1234，内壳体侧壁1234沿周向环绕内壳体底壁1232以形成一端开口的雾化腔1236，内壳体侧壁1234远离内壳体底壁1232的一端开设有至少一个连通雾化腔1236与内壳体123的外环境的内壳体进气孔1234a。内壳体123至少部分收容于主壳体120的容纳腔内，雾化腔1236的开口端与容纳腔的开口端同轴且位于主壳体120的同一端。作为一较佳的实施方式，内壳体侧壁1234远离内壳体底壁1232的一端端面与外壳体侧壁1214远离外壳体底壁1212的一端端面齐平。
进一步地，外壳体121的外壳体底壁1212的内表面凸设有伸入容纳腔的底壁限位凸起1212b，外壳体侧壁1214远离外壳体底壁1212的一端的内表面凸设有侧壁限位凸起1214a，侧壁限位凸起1214a沿外壳体侧壁1214的周向延伸并伸入容纳腔。收容于容纳腔内的内壳体123的内壳体底壁1232支撑于底壁限位突起上，内壳体侧壁1234则抵持于侧壁限位凸起1214a。
如此，外壳体121和内壳体123之间界定形成允许气流流过的进气通道125，进气通道125的一端通过外壳体进气孔1212a连通外界环境，进气通道125的另一端通过内壳体进气孔1234a连通雾化腔1236。外界环境中的空气从外壳体进气孔1212a进入进气通道125，然后朝容纳腔的开口端流动并通过内壳体进气孔1234a进入雾化腔1236，最后携带雾化腔1236中产生的气溶胶流出。
请继续参阅图1，线圈140沿周向缠绕于外壳体侧壁1214外，并自外壳体侧壁1214的轴向上的一端延伸至外壳体侧壁1214的另一端。申请人在研究中发现，在发热体160的尺寸较大、预热期较短的情况下，发热体160的加热功率较大，线圈140的匝数较少，线圈140匝与匝之间的间距较大。因此，本申请的线圈140呈多线并绕结构，即，线圈140通过多线并绕的方式缠绕于外壳体侧壁1214外，从 而填补匝间位置，在与单线绕线结构具有相同的电流密度的情况下可以减少线圈140的径向尺寸，使线圈140的厚度整体变薄而有利于外壳体121散热。作为一较佳的实施方式，线圈140采用2-3束直径相同的导线并绕的结构。
为了达到较高的能量转换效率，发热体160呈竖直状态悬浮于气溶胶生成基质200中，发热体160具有与雾化腔1236的轴向平行的长度方向，即，发热体160在雾化腔1236的轴向上的长度大于其在雾化腔1236的径向方向上的长度，因此可充分利用线圈140产生的交变磁场。而为了使悬浮于气溶胶生成基质200中的发热体160保持竖直状态，发热体160被配置为偏心结构，发热体160的重心位于发热体160的长度方向上的一端。如此，在重力作用下，悬浮于气溶胶生成基质200中的发热体160的重心始终朝下，发热体160始终保持竖直状态。
请参阅图1及图3，进一步地，发热体160呈回转体状结构，发热体160具有一沿自身长度方向延伸的中心线L，为了使发热体160更准确地维持竖直状态，发热体160的重心位于中心线L上。如此，在重力作用下，悬浮于气溶胶生成基质200中的发热体160始终准确地保持竖直状态，有效防止发热体160向四周倾斜。其中，悬浮于气溶胶生成基质200中的发热体160至少部分浸没于气溶胶生成基质200中，即，发热体160的一部分浸没于气溶胶生成基质200中，发热体160的另一部伸出气溶胶生成基质200，或者发热体160全部浸没于气溶胶生成基质200中。
具体地，发热体160包括发热壳体161及配重单元163。发热壳体161呈中空的壳体状结构，发热壳体161的内部形成封闭的容置腔1611，配重单元163收容于容置腔1611内。如此，配重单元163的位置决定了发热体160的重心位置。当配重单元163位于发热壳体161的长度方向上一端时，发热体160的重心位于配重单元163所在的一端，从而使悬浮于气溶胶生成基质200中的发热体160保持竖直状态。
而为了使发热体160更准确地维持竖直状态，发热壳体161包括在其长度方向上依次设置的第一发热部1612、第二发热部1614以及第三发热部1615。第二发热部1614连接于第一发热部1612和第三发热部1615之间，第一发热部1612和第三发热部1615中的至少一者呈背向第二发热部1614向外凸出的球冠状，且第一发热部1612的顶点和第二发热部1614的顶点的连线与发热体160的中心线L重合。
当发热体160悬浮于气溶胶生成基质200时，配重单元163在重力作用下至少部分限位于第三发热部1615中，因此发热体1615处于竖直状态，第三发热部1615位于发热体160的底端，第一发热部1612位于发热体160的顶端。由于第一发热部1612的顶点和第二发热部1614的顶点的连线与发热体160的中心线L重合，从而可避免配重单元163在发热壳体161的径向方向上移动，进而保证配重单元163的重心位于发热体160中心线L上，最终保证发热体160的重心位于发热体160的中心线L中。
作为一较佳的实施方式，如此，第二发热部1614的外表面相对于雾化腔1236的中心轴线倾斜延伸， 在发热体160的长度不变的情况下，外表面倾斜延伸第一发热部1612具有更大的表面积，从而进一步提高了发热体160的能量转换效率。
如图3所示，具体在一实施例中，发热壳体161的第二发热部1614的外径处处相等，发热壳体161的纵截面呈腰型，第一发热部1612和第二发热部1614的半径相同。
如图4所示，具体在另一实施例中，第一发热部1612的外径小于第三发热部1615的外径，第二发热部1614的外径自连接第一发热部1612的一端至连接第三发热部1615的一端逐渐减小，发热壳体161的纵截面包括两个大小不同的圆弧段及连接于两个圆弧段之间的直线段，两个直线段以中心线L的对称轴对称，且每条直线段的延伸方向相对中心线倾斜以与中心线形成夹角α，优选的，0°≤α≤30°。如此，在发热体160的长度不变的情况下，第二发热部1614具有更大的表面积，从而进一步提高了发热体160的能量转换效率。
如图5所示，本申请还提供一实施例，发热体160的第二发热部1614的外径自连接第一发热部1612的一端至另一端先逐渐增大后逐渐减小，发热壳体161的纵截面呈椭圆形，第一发热部1612和第二发热部1614的半径相同。
在上述实施例中，发热壳体161的侧壁厚度为0.05mm-0.4mm，优选为0.1mm-0.12mm。发热壳体161由磁性金属导体材料形成，包括铁、铁基合金、镍、镍基合金或4系列不锈钢中一种或多种，且上述磁性金属导体材料的外表面可覆盖陶瓷釉料或耐高温抗氧化金属材料(例如钛)以起到保护作用。可以理解，发热壳体161的形状、厚度以及制造材料不限，可根据需要设置以满足不同要求。
配重单元163由球状、颗粒状或粉末状中至少一者形成，且球状的配重单元163的外径小于第一发热部1612的内径。配重单元163由热不良导体材料形成，从而减少对发热壳体161的热量的吸收，进而减少发热壳体161的热量损失。具体地，配重单元163可由玻璃、低导热系数陶瓷(例如氧化锆)、黏土和二氧化硅中的一种或多种材料形成。可以理解，配重单元163的形态以及制造材料不限，可根据需要设置以满足不同要求。
在其它一些实施例中，发热体160呈块状结构，发热体160由单位质量不同的多种材料形成，单位质量不同的材料分布于发热体160的不同区域，从而使发热体160形成偏心结构。
在一些实施例中，可通过控制发热壳体161的加热功率以使气溶胶生成基质200在最佳温度下加热。具体地，在预热期，线圈140采用大功率工作以使发热体160迅速达到最佳温度，在恒温期，线圈140采用小功率工作以保持发热体160的温度，从而达到良好的加热效果。其中，气溶胶生成基质200的最佳加热温度等于发热体160居里温度点。
上述雾化组件100及电子雾化器，通过悬浮于气溶胶生成基质200中的发热体160加热气溶胶生成基质200，有效缩短了预热时间，提升了能量利用率，同时降低了主壳体120的外壁温度而便于使用者 持握，且发热体160的外表面光滑延伸，因此可以方便地进行清洁。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
