具体的，该雾化器20可包括雾化套管21和导热体22。
在具体实施例中，雾化器20还包括发热体(图未示)，发热体设置在雾化套管21内，用于在通电时加热并雾化烟油。具体的，雾化套管21内具有雾化腔，发热体具体容置在雾化腔内，并在通电时对进入雾化腔内的烟油进行加热；可以理解的是，发热体发热产生的热量经热传导会传导至雾化套管21上。
其中，雾化套管21具体可为一柱状体，且具有相对设置的第一端和第二端，导热体22具体与雾化套管21的第一端抵接，使得雾化套管21上的热量直接传导至导热体22，从而分散雾化套管21上的热量，避免热量集中而导致烫手的问题发生。在具体实施例中，雾化器20具有烟嘴，雾化套管21的第二端为朝向烟嘴的一端，并可与烟嘴连接。

具体的，参见图4，在一个实施例中，第二导热部222和第一导热部221均可为空心圆柱体，第二导热部222和第一导热部221轴向连接， 同轴设置且第一导热部221的直径小于第二导热部222的直径。具体的，第二导热部222的外侧壁上设置有凸缘223，凸缘223远离第二导热部222的外侧壁的一侧具体与外壳体23的内侧壁抵接，凸缘223与第二导热部222的外侧壁和外壳体23配合形成第一气道；其中，凸缘223具体可与第二导热部222的外侧壁一体成型；第一气道的一端与雾化腔连通，另一端与外界空气连通，以使外界空气能够经由第一气道进入雾化腔内，从而延长空气在第二导热部222上的流经路径，使得经过第一气道的空气能够尽可能多地带走第二导热部222上的热量，以达到进一步降温的目的；同时，可通过第二导热部222上的温度对新进的空气进行预热，以提高发热体的热利用率，且使用户吸入的空气具有一定温度，避免吸入凉气影响用户体验。

具体的，在该实施例中，可进一步在每个环形凸起223a设置多个缺口226，并使相邻两个环形凸起223a上的各个缺口226错位设置，以保证空气在第二导热部222上具有一定长度的流经路径的同时，降低空气吸阻。

具体的，雾化套管31的第一端与导热体33朝向储液腔外壳32的一侧表面抵接，以使雾化套管31上的热量能够传导至导热体33上，进而通过导热体33分散雾化套管31上的部分热量，以避免热量局部集中而导致烫手的问题发生。
在具体实施例中，导热体33可为柱状体，且导热体33上开设有进气孔342，进气孔342的一端与大气连通，另一端与雾化腔连通，以使外界空气能够经由进气孔342进入雾化腔内。

在另一实施例中，参见图15，图15为本申请另一实施例提供的图10所示雾化器的A-A向的剖视图；与上述实施例不同的是，外壳体34对应隔热空间S’的位置没有开设通气孔341，外壳体34与密封部332和雾化套管31的外侧壁配合形成一完全密封的隔热空间S’。通气孔341具体开设在底座35上，且在一具体实施例中，通气孔341沿底座35的轴向方向延伸；进气孔342具体开设在导热部331上，并沿导热部331的轴向方向延伸；在一具体实施例中，通气孔341与进气孔342的中心轴相同，且通气孔341的孔径小于进气孔342的孔径。

具体的，在该实施例中，由于第一气道的路径较长，用户的抽吸过程中所受的吸阻较大，为了在延长空气的流经路径的同时，降低吸阻，使抽吸更加顺畅；进一步可在环形槽3321的槽壁上设置若干缺口3322， 并使若干缺口3322在密封部332的轴向方向上错位设置；其中，环形槽3321的槽壁相当于上述实施例中的环形凸起223；可以理解的是，在该实施例中，参见图5，环形槽3321具体可通过缺口3322分割为多个沿密封部332的轴向方向间隔设置且通过缺口3322相互连通的长度较短的子环形槽；具体的，在该实施例中，每个子环形槽具体呈倾斜状态；外界空气可从通气孔341进入其中一个子环形槽，并在缺口3322处可直接进入与当前子环形槽连通的其它子环形槽，从而大大缩短了空气的流经路径，有效降低了吸阻。
在另一具体实施例中，参见图6，环形槽3321包括多个圆环形槽3321a，多个圆环形槽3321a沿密封部332的轴向方向间隔设置，且圆环形槽3321a所在的平面与密封部332的轴向方向垂直，即，圆环形槽3321a沿平行于密封部332的径向方向设置，这样能够降低工艺难度系数，方便技术人员加工；具体的，在该实施例中，每个圆环形槽3321a的槽壁具有至少一个缺口3322，以使相邻两个圆环形槽3321a连通，进而使外界空气能够经由各个圆环形槽3321a、进气孔342进入雾化腔内。具体的，为了延长空气在通气孔341与进气孔342之间的路径，可使相邻两个圆环形槽3321a的槽壁上的缺口3322错位设置。当然，在其他实施例中，圆环形槽3321a所在的平面也可朝向导热体33的方向倾斜设置。
具体的，在该实施例中，可进一步在每个圆环形槽3321a的槽壁上设置多个缺口3322，并使相邻两个圆环形槽3321a的槽壁上的各个缺口3322错位设置，以保证空气在密封部332上具有一定长度的流经路径的同时，降低空气吸阻。
进一步地，在具体实施例中，可在储液腔外壳32和导热部331的外侧壁上套设散热套36，以通过散热套36吸收部分储液腔外壳32和导热部331上的温度，从而降低传导至外壳体34上的热量。其中，散热套36的材质具体可为塑料。
具体的，参见图17，图17为本申请一实施例提供的散热套的结构示意图；具体的，散热套36具体可包括连接套361和设置在连接套361的外侧壁上的若干连接条362；其中，连接套361具体可为环形套，用 于嵌入凹陷部并套设在导热部331的外侧壁上；且在具体实施例中，连接套361的厚度H 1与凹陷部的深度H 2和长度L 1相同；若干连接条362具体可为条状体，且连接条362的轴向长度大于连接套361的轴向长度，连接条362沿储液腔外壳32的径向方向上的厚度H 3与隔热空间S’的宽度W 1相同；具体的，若干连接条362沿连接套361的周向方向间隔设置，且连接条362的延伸方向与连接套361的轴向方向相同，相邻两个连接条362与连接套361的外侧壁配合形成第一通气槽3323；在一具体实施例中，连接条362的设置于连接套361的外表面的其中一个端部，与连接套361的靠近导热部331的一端部平齐，以使每个第一通气槽3323从连接套361的靠近导热部331的一端延伸至另一端；同时，每两个连接条362的靠近连接套361的一端连接在一起，以使第一通气槽3323的一端为封闭端；在具体实施例中，若干连接条362用于套设在储液腔外壳32的外侧壁上，并与储液腔外壳32的外侧壁配合形成若干第二通气槽；可以理解的是，第一通气槽3323远离第二通气槽的一端为封闭端，第一通气槽3323与第二通气槽连通。
在具体实施例中，第一通气槽3323和至少一对相邻设置的第二通气槽与外壳体34的内侧壁配合形成第二气道，第二气道与第一气道连通，以使经过第一气道的空气进一步经过第二气道进入进气孔342内，从而使空气可进一步流经储液腔外壳32所在的表面，进而能够带走储液腔外壳32上的热量，以降低储液腔外壳32上的温度。第二气道与第一气道的连通方式具体可参见上述实施例中相关的连通方式，在此不再赘述。
需要说明的是，在该实施例中，设置在导热部331上的进气孔342与连接套361上形成的第一通气槽3323的位置对应，且连接套361对应进气孔342的位置开设有通孔，该通孔与进气孔342连通，以使空气经由第二气道之后进入进气孔342，从而使经过第一气道的空气能够进一步流经第二气道，进而带走部分储液腔外壳32上的热量，以进一步降低传导至外壳体34上的热量。
在本实施例中，参见图18，图18为本申请一实施例提供的电子雾 化装置的结构示意图；提供一种电子雾化装置100，该电子雾化装置100具体可为电子烟；具体的，该电子雾化装置100可包括电源组件101和与电源组件101连接的雾化器102。
