该第一支撑臂112和该第二支撑臂113在一些实施例中可呈板状。第一支撑臂112和第二支撑臂113的内侧面还设有分别凹陷形成有收容槽1122、1132，以供上座体14的嵌套部142嵌置于其中。收容槽1122、1132形成于第一支撑臂112和第二支撑臂113的上半部，并分别在第一支撑臂112和第二支撑臂113上形成有台阶1126、1136。雾化组件12的两端分别搭接在台阶1126、1136上。第一支撑臂112和第二支撑臂113的顶端外侧还分别设有用于与上座体14卡扣的卡合部1122、1132。在一些实施例中，第一支撑臂112和第二支撑臂113呈左右对称设置，以方便组装；也即组装时，组装人员可以不用先分辨那端是左，那端是右。
下座体11在一些实施例中还可包括U型的进气槽结构114和U型的出气槽结构115，进气槽结构114和出气槽结构115分别连接于第一支撑臂112和第二支撑臂113的外侧，并均水平向外延伸。该第一支撑臂112上形成有将进气槽结构114与雾化腔110相连通的通孔1120，该第二支撑臂113上形成有将出气槽结构115与雾化腔110相连通的通孔1130，以引入空气将雾化腔110中的烟气带走；通孔1120、1130分别位于收容槽1122、1132的下方。
上座体14在一些实施例中可包括大致呈长方体的主体部141、由主体部141的底面中部向下伸出的嵌套部142以及由主体部141的底面右端部向下伸出的第二进气通道143。该嵌套部142呈环形，其容置于下座体111的第一支撑臂112和第二支撑臂113之间的收容槽1122、1132中，并套设在密封套13外围。上座体14还包括两个由主体部141的顶面延伸至底面的液体通道144、形成于侧壁上的环绕右侧液体通道144且与第二进气通道143相连通的槽道145以及与槽道145相连通的第二出气通道146，第二出气通道146由上座体14的顶面中部贯穿连通至槽道145。上座体14的顶面左端还向下凹陷形成两个定位孔147，以与套体15相配合，起到定位和防呆的功能。上座体14还包括向下伸出的卡勾148，以勾扣在下座体11上。
套体15在一些实施例中可为硅胶套，其可包括顶壁151、由顶壁151周缘向下延伸的环状第一挡壁152以及分别自第一挡壁152的两端向下伸出的两个U型第二挡壁153和154。顶壁151上形成有两个进液孔155以及一个套体出气通道156，该两个进液孔155分别与上座体14的两个液体通道144对应，该套体出气通道156插设于上座体14的第二出气通道146中，与第二出气通道146相连通。第一挡壁152用于包覆在上座体112的主体部141的侧壁上，覆盖在侧壁上的槽道145，形成一个密闭的环形上座体连接通道。第二挡壁153和154分别覆盖在下座体111的进气槽结构1114和出气槽结构1115上，与第一支撑臂1112和第二支撑臂115一道分别形成密闭的第一进气通道和第一出气通道。左侧第二挡壁153上形成有一个第一进气孔157，该第一进气孔157用于与外界环境相连通，以将空气引入该第一进气通道。该第一出气通道与第二进气通道143相连通。套体15的顶壁151底面的左端向下伸出有两个定位柱158，以分别与上座体14的两个定位孔147配合，主要是为了让套体15左侧的第一进气孔157能够准确地位于上座体112和下座体111的组合体的左侧，保证其与第一进气通道是连通的，起到防呆功能。
储液单元20在一些实施例中可包括带有出气口210的壳体21以及设置于壳体21中且与该出气口210相连通的气流管道22。该壳体21包括储液部211以及与该储液部211相连接的套接部212，该储液部211与该气流管道22之间形成有储液腔23，该储液腔23包括一个出液口230，该套接部212连接于该出液口230的周缘，用于紧密地套接在雾化单元10上。套接部212的内壁面与储液部211的内壁面之间形成有一个台阶213，该台阶213抵靠在雾化单元10的顶面上。在一些实施例中，该套接部212与该储液部211一体成型。出气口210处可以被设置呈扁平的喇叭状作为吸嘴。
该气流管道22由出气口210朝出液口230延伸，且末端延伸至套接部212内，插置在套体15的出气孔156中，进而与该第二出气通道146相连通。该套接部212的左右两侧上还设有第二进气孔2120，其中左侧的第二进气孔2120与套体15的第一进气孔157相连通，从而可以让壳体21外部的空气进入套体15与下座体11形成的第一进气通道内。优选地，壳体21整体呈对称设置，以方便组装；因为，如果只有一侧有第二进气孔2120，工人组装时需要增加第二进气孔2120是否与第一进气孔157处于同一侧的判断步骤。该套接部212的左右两侧内壁面上还形成有卡槽2122，以分别与下座体111的卡勾1112相配合，让壳体21与下座体111能够方便地卡扣在一起。
雾化器1组装时，可以采用如下步骤：
（1）
先将密封套13套在雾化组件12上；
（2）
将密封套13和雾化组件12的组合体塞到上座体14的嵌套部142中；
（3）
再将上座体14盖在下座体11上，让上座体14的让雾化组件的卡勾148卡扣到下座体11的卡合部1122、1132上，实现上座体14与下座体11的卡扣连接；同时让雾化组件12的电极引线与下座体11上的电极柱1114电性连接；
（4）
再将套体15套接到上座体14上，完成雾化单元10的组装；
（5）
最后将倒着塞入装有烟液的储液单元20的套接部212中，顶面与台阶213相抵，封堵住储液腔23的出液口230，并让下座体11的卡勾1112卡入套接部212的卡槽2122中，实现雾化器1的组装，组装非常方便快捷。
由此，空气在雾化器1中流动路径如图32的箭头所示：空气首先通过第二进气孔2120及第一进气孔157进入到第一进气通道，然后再通过通孔1120进入雾化腔110与气溶胶混合。气溶胶空气混合物再通过通孔1130进入第一出气通道，然后进入第二进气通道143。再进入环形上座体连接通道，然后进入第二出气通道1466。最后进入气流管道22，最后经由出气口210排出雾化器1。储液腔23中的烟液则依次经过套体15的进液孔155和上座体14的液体通道144，进入到雾化组件12的凹槽120中，与吸液面接触，实现液体的导送。
在一些实施例中，第二进气孔2120的位置高于雾化腔110，此种设置可以较好地防止正常使用状态下泄漏烟液从第二进气孔2120处流出。雾化器1整个气流通道底部呈大致U型，位于雾化腔110位置的气流方向与雾化组件12的雾化面1211平行，更加容易带走雾化面1211雾化的烟气。
如图8至图11所示，雾化组件12在一些实施例中可包括用于吸取气溶胶生成基质的多孔陶瓷体121以及结合于该多孔陶瓷体121上、以将多孔陶瓷体121吸取的气溶胶生成基质进行加热雾化的发热元件122。
该多孔陶瓷体121在一些实施例中可大致呈长方体状，其包括用于吸液的第一表面1211以及与该第一表面1211相对的第二表面1212，该第一表面1211中部朝向第二表面1212内凹形成有一个凹槽1210，使得该多孔陶瓷体121大致呈碗型。多孔陶瓷体121大致呈碗型一方面整体的高度足够高，方便于雾化组件12的安装以及密封套115的设置；另一方面，保证吸液面到雾化面1211的距离足够近，以在方便安装时，又保证了雾化效果。
凹槽1210的内表面形成多孔陶瓷体121的吸液面，凹槽1210可以增加吸液面积，方便气溶胶生成基质的传输。该多孔陶瓷体121的第二表面1212中部朝向第一表面1211内凹的形成一个横截面呈弧形的雾化面1213，以供发热元件122容置于其中，对气溶胶生成基质进行加热雾化。可以理解地，多孔陶瓷体121并不局限于呈长方体状，其也可以呈圆柱状等其他适合的形状。
多孔陶瓷体121在一些实施例中还可包括一对挡墙1214，该一对挡墙1214分别设置于该雾化面1213的两相对长边上，以进一步抵挡发热元件122，防止雾化组件12在成型过程中发热元件122在翘起。
发热元件122在一些实施例中可采用金属发热片通过冲压等方式一体成型，其可包括平板状的第一导电部1221、平板状的第二导电部1223以及位于第一导电部1221和第二导电部1223之间的弧形板状发热部1222，该弧形板状发热部1222部分地或全部地嵌置于多孔陶瓷体121的雾化面1213上，以在烧结成型过程中，多孔陶瓷体收缩时，会压紧发热元件，防止发热部1222翘起。优选地，该发热部1222被镂空呈S型，以提升方便热阻的分布。
发热元件122在一些实施例中可包括一对第一固定部1224和一对第二固定部1225；该一对第一固定部1224呈片状，并分别垂直设置于第一导电部1221的两相对侧边；该一对第二固定部1225呈片状，并分别垂直设置于该第二导电部1222的两相对侧边。该一对第一固定部1224和该一对第二固定部1225分别嵌置于该多孔陶瓷体121中，以让发热元件122与多孔陶瓷体121的结合更加紧固。
以上所述仅为本发明的实施例，并非因此限制本发明的专利范围，凡是利用本发明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，均同理包括在本发明的专利保护范围内。
