电子烟是一种利用加热丝对烟液进行加热，使之雾化的电子产品，为吸烟者提供一种香烟的替代品。加热后的烟液变成气雾，通过通气管后从吸嘴盖的开口到达电子烟的外部。一般需要在电子烟的雾化器上使用密封圈，防止烟液从吸嘴盖处漏液，避免吸烟者直接吸到烟液。
但是加了原有的密封圈的电子烟在吸烟过程中吸嘴盖处容易冷凝烟液，由于密封圈隔绝冷凝烟液回流到储油棉上，造成吸烟时容易吸到冷凝的烟液。

本发明还提供一种电子烟雾化器，包括雾化套及设置在雾化套内的电子烟密封圈，电子烟密封圈设置有通气孔；雾化套内，位于电子烟密封圈的两侧分别形成有烟液 冷凝腔及烟液储液腔；烟液储液腔内设置有吸油材料， 其特征在于，电子烟密封圈的周缘与通气孔之间开设有至少一贯穿电子烟密封圈的回流孔，回流孔与烟液 冷凝腔及烟液储液腔相连通 。
本发明的电子烟雾化器，包括 依次设置在雾化套内的外螺纹套、上电极、绝缘环、雾化座、电热阻丝组件、通气管、储油棉； 还包括电子烟密封圈， 电子烟密封圈设置在储油棉的底端； 电子烟雾化器还包括套合在远离 外螺纹套一端的雾化套内的吸嘴盖，吸嘴盖与电子烟密封圈之间形成烟液冷凝腔； 电子烟密封圈上设置有连通烟液冷凝腔至储油棉的回流孔。

图1为雾化器的侧面剖视图；
图2为雾化器的分解示意图；
图3为电子烟密封圈的侧面剖视图；
图4.a为电子烟密封圈第一实施例的底视图；
图4.b为电子烟密封圈第二实施例的底视图；

图5为吸嘴盖的剖视图。
具体实施方式
以下结合附图和具体实施方式对本发明进行详细说明。
如图1和图2所示为安装了本发明电子烟密封圈的雾化器结构。整个雾化器包括自首端至末端依次设置的外螺纹套100、上电极200、绝缘环300、雾化座410、电热阻丝组件500、通气管600、储油棉700、电子烟密封圈800、吸嘴盖900，所有的组件装配在雾化套420内。绝缘环300设置在外螺纹套100和上电极200之间，使外螺纹套100和上电极200电性隔绝。电热丝组件500为一个'凵'形架，其两端的引脚穿过雾化座410后分别电连接电极200和外螺纹套100。储油棉700储存有液态的烟液，储油棉700设置在雾化座410和电子烟密封圈800之间。通气管600为中通结构，设置在储油棉700中间。吸嘴盖900与电子烟密封圈800之间还形成一个空腔。
雾化器工作的时候，外部电源的正负极分别连接到外螺纹套100和上电极200，电热阻丝组件500将外部电源的电能转化为热能，在通气管600内将储油棉700的烟液雾化成气体，雾化后的气体沿着通气管600通过电子烟密封圈800后，从吸嘴盖900的通孔到达外界。
当雾化后的气体通过吸嘴盖900与电子烟密封圈800之间形成的空腔时，可能会有部分残留，在吸嘴盖900处容易冷凝烟液，为了避免直接吸到这些冷凝的烟液，在电子烟密封圈800对应于储油棉700的位置开设有回流孔，使冷凝的烟液回流到储油棉700中。
以下结合图3、图4.a~图4.c具体说明密封圈的结构。电子烟密封圈800主要包括一个中间开有通气孔860的密封圈底盖810，在密封圈底盖810的边缘处，沿着垂直于密封圈底盖810所在平面的方向延伸出外壁820；在通气孔860的边缘处，沿着和外壁820相同的延伸方向，延伸出内壁830；内壁830和外壁820之间形成一个凹槽840。储油棉700的一端紧密卡嵌在凹槽840内，与内壁830、外壁820、密封圈底盖810贴合。在凹槽840所在的密封圈底盖810处开设有回流孔850，供冷凝后的烟液从密封圈底盖810外经过回流孔850到达凹槽840内的储油棉700。
回流孔850的形状、数量可以依据实际需要进行设置。例如在图4.a中，设置4个弧形孔。为了保证回流的烟液能够平均地流到储油棉700中，弧形孔与中间的通气孔860具有相同圆心。需要理解的是，当弧形孔扩大的时候，还可以变成一个圆环状的通孔。
图4.b中设置6个圆形孔，基于此形状，回流孔850还可以变形成椭圆形孔。在图4.b中，所有的圆形孔围绕中间的通气孔860平均分布，使得烟液能够平均地流到储油棉700中。
图4.c中，围绕中间通气孔860平均分布了6个正三角形的回流孔。正三角形还能改为四边形、多边形或者不规则的形状。
以下结合图5的吸嘴盖结构详细说明雾化后的烟液如何回流到储油棉中。吸嘴盖900包括带有中心孔的盖板910，从盖板910的边缘垂直延伸有用于连接雾化套420的外筒壁920、从盖板的吸气孔960的周缘轴向延伸形成一朝向与外筒壁920同向的内筒930，内筒930与外筒壁920之间具有第二凹槽940，第二凹槽940与电子烟密封圈800之间形成烟液冷凝腔。当雾化后的烟液通过通气孔860后首先到达烟液冷凝腔，再通过吸嘴盖900上的中心孔到达外界。当部分的雾化烟液在烟液冷凝腔内残留时，会冷却重新变回液态的烟液，由于在密封圈上设置有回流孔850使得冷凝的烟液可以从烟液冷凝腔经过回流孔850回到储油棉中。由于储油棉的吸附能力很强，冷凝的烟液会迅速被储油棉吸收，不会从吸嘴盖的中心孔被吸出。
以上仅为本发明具体实施方式，不能以此来限定本发明的范围，本技术领域内的一般技术人员根据本创作所作的均等变化，以及本领域内技术人员熟知的改变，都应仍属本发明涵盖的范围。
