图1为本申请一实施例中的雾化器的结构示意图；图2为图1所示的雾化器的剖面结 构示意图；图3为图1所示的雾化器的雾化组件的结构示意图；图4为图1所示的雾化器的雾化组件的另一视角的结构示意图。为便于描述，附图中仅示出了与本申请相关的结构。
本申请至少一实施例公开的电子雾化装置包括电源组件及雾化器100，电源组件与雾化器100电连接，用于向雾化可雾化介质的雾化器100提供能量。其中，可雾化介质可以是烟油、药液等介质，可雾化介质被雾化后形成可供用户吸食的气溶胶。
请参阅图1和图2，雾化器100包括壳体10及设于壳体10内的雾化组件20。雾化组件20包括具有雾化腔211的雾化座21及雾化芯，雾化座21的顶部开设有与雾化腔211连通的出液孔212，且雾化座21的顶部与壳体10的内壁围合形成用于存储可雾化介质的储液腔。雾化芯设于雾化腔211内，用于雾化可雾化介质。
雾化器100还包括沿自身轴向设置于壳体10内的中心管30，储液腔环绕中心管30设置，中心管30连通雾化腔211与外部。在实际使用中，储液腔内的可雾化介质通过出液孔212进入到雾化腔211，然后由雾化芯吸附并雾化。雾化形成的气溶胶通过中心管30传输到外部，例如用户的嘴中。
但是，在雾化器100的使用后期，可雾化介质剩余量不多时，流动性会越来越差，导致可雾化介质难以流动至出液孔212内，从而残留在雾化座21的顶部。
请参阅图2-4，故，在雾化座21的顶部设置有朝着出液孔212以下行坡度倾斜的导流面213。导流面213以下行坡度朝出液孔212倾斜设置的意思是，导流面213远离出液孔212的部分的垂直高度高于导流面213靠近出液孔212的部分的垂直高度，也即导流面213被构造为具有一有利于可雾化介质流向出液孔212的高度差。
在实际使用中，雾化座21顶部残余的可雾化介质能够借助导流面213，将自身的重力势能转化为动能，被快速地导流至出液孔212内，进而进入到雾化腔211内被雾化芯雾化。如此，降低了可雾化介质的残留率，提高了可雾化介质的利用率。
壳体10沿自身径向的截面形状呈椭圆状，雾化座21沿自身径向的截面形状为与壳体10相匹配的椭圆状，以与壳体10适配。因此，雾化座21具有长轴和短轴。
雾化组件20还包括密封件23，密封件23密封设置于雾化座21的顶部，出液孔212开设于密封件23上并延伸至雾化腔211内。具体地，密封件23密封于壳体10内表面与雾化座21之间，用于防止储液腔内的可雾化介质从壳体10与雾化座21之间的配合间隙泄露，影响用户体验。更具体地，密封件23可以为由硅胶材料制成的密封硅胶，当然也可以由其他材料制成，本申请在此并不作具体限定，只要能够保证密封性即可。
需要说明的是，密封件23配接在雾化座21上后，储液腔是由密封件23背离雾化座 21的顶部配合壳体10内壁围合形成。密封件23背离雾化座21的表面被构造形成有导流面213。也即，密封件23背离雾化座21的顶部具有朝着出液孔212以下行坡度倾斜的导流面213，以防止可雾化介质残留。
出液孔212包括沿雾化座21的长轴方向间隔设置的两个，两个出液孔212相互背离的一侧均布设有一导流面213。具体地，出液孔212包括位于中心管30两侧的两个，每一出液孔212远离中心管30的一侧布设有一导流面213。
更具体地，密封件23上贯穿自身设置有一个中心孔和两个出液孔212，中心孔沿雾化座21的长轴方向设于密封件23中间，两个出液孔212沿雾化座21的长轴方向分别间隔设于中心孔的相对两端。在每一出液孔212远离中心管30的一侧布设有朝着出液孔212以下行坡度倾斜的导流面213。
在实际使用中，雾化器100的使用后期，可雾化介质容易残留在两个出液孔212相互背离的一侧，也即每一出液孔212远离中心管30的一侧，通过在每一出液孔212远离中心管30的一侧布设有一导流面213，将有利于残留在两个出液孔212相互背离一侧的可雾化介质流向出液孔212内，从而减少可雾化介质残留率，提高可雾化介质利用率。
在一些实施例中，导流面213沿雾化座21的长轴方向位于出液孔212的至少一侧。具体到一些实施例中，导流面213沿雾化座21的长轴方向位于出液孔212的一侧，也可以位于出液孔212的两侧。
容易理解的是，本来可雾化介质就是主要残留在出液孔212沿雾化座21的长轴方向的一侧，若只沿雾化座21的长轴方向在出液孔212的一侧设置导流面213，将导致没有导流面213的另一侧容易残留可雾化介质，因此还是存在可雾化介质利用率不高的问题。故，在优选实施例中，导流面213沿雾化座21的长轴方向位于出液孔212的两侧。
在一些实施例中，导流面213沿雾化座21的短轴方向位于出液孔212的至少一侧。具体到一些实施例中，导流面213沿雾化座21的短轴方向位于出液孔212的一侧，也可以位于出液孔212的两侧。
容易理解的是，若只沿雾化座21的短轴方向在出液孔212的一侧设置导流面213，将导致没有导流面213的另一侧容易残留可雾化介质，因此还是存在可雾化介质利用率不高的问题。故，在优选实施例中，导流面213沿雾化座21的短轴方向位于出液孔212的两侧。
可以理解的是，上述仅为了举例说明，并不能理解为对本申请的限定。例如，导流面213不局限于沿雾化座21的短轴方向或者长轴方向设于出液孔212的侧边，也可以沿其他 方向设置在相应位置。因此，在实际生产设计过程中，导流面213应该根据需要而设定。
在一些实施例中，导流面213包括平面、曲面，或者平面与曲面的组合。曲面可以是阶梯状、弧面状等形状，也即，导流面213不仅可以为平面，也可以为上述形态的曲面，只要液体可以沿着这个导流面213导入到出液孔212中即可。
在一些实施例中，导流面213为以下行坡度倾斜的平面，且与出液孔212轴向之间形成夹角，该夹角为0～90度。在优选实施例中，该夹角为10～30度。需要说明的是，夹角需要结合实际需求进行设计。
上述的雾化组件20、雾化器100及电子雾化装置，雾化座21的顶部具有朝着出液孔212以下行坡地倾斜的导流面213。在雾化器100使用后期，倾斜设置的雾化座21顶部有利于剩余残留的可雾化介质朝出液孔212流动，从而可从出液孔212排出到雾化腔211。如此，能够减少可雾化介质残留，提高可雾化介质的利用率。
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。
