 本发明的实施方式
为了对本发明的技术特征、目的和效果有更加清楚的理解，现对照附图详细说明本发明的具体实施方式。
如图1、2所示，本发明第一实施例的电子烟的气流开关支架，包括基座10。在电子烟中，以基座10朝向烟嘴的一面为顶面，相对的另一面则为底面。基座10的底面设有凹槽101，用于容置定位气流开关。
其中，凹槽101自基座10的底面向基座10的顶面方向延伸，不贯穿基座10的顶面，使基座10的顶面形成有一密封在凹槽101上的薄壁层102。从基座10上看，凹槽101开口朝下，薄壁层102也构成凹槽101的顶端。
薄壁层102可与基座10为一体模压成型的一体结构，其在厚度方面较基座10的其他部分小，可薄至接近或等于薄膜的厚度，从而可以发生形变及复原。
薄壁层102的厚度可为0.05±0.02mm。
在电子烟中，薄壁层102在气流经过时可发生形变，使凹槽101和气流开关之间的空间产生负压而控制气流开关的启闭， 从而不需要设置通孔供气流通过，进而也杜绝了烟液等液体从通孔漏到气流开关、供电装置上导致的污染问题。
凹槽101进一步可包括相连通的第一槽部111和第二槽部112。气流开关主要容置在第一槽部111，气流开关容置在第一槽部111内时其外周与第一槽部111的内周密封配合。第二槽部112位于第一槽部111和薄壁层102之间，留空在气流开关和薄壁层102之间，且该第二槽部112可在气流经过薄壁层102时产生负压，使气流开关开启或关闭。
本实施例中，第二槽部112的外周尺寸小于第一槽部111的外周尺寸。例如，对于圆形的凹槽101，第一槽部111的直径大于第二槽部112的直径，两者的连接处形成有台阶面，气流开关的顶部可抵接台阶面。
本实施例中，基座10的底面还设有两个电极槽103，用于容置电极。两个电极槽103位于凹槽101的两侧且与凹槽101隔绝不连通。基座10的顶面设有两个电极孔104，用于电极的端部穿出基座10。两个电极孔104位于薄壁层102的两侧，且分别对应在两个电极槽103的上方，连通对应的电极槽103。
在电子烟中，气流开关支架安装在供电装置中。如图1所示，本实施例中，基座10整体呈矩形结构，两个长边为弧形，该种形状的基座10适用于扁平状（非圆柱状）的供电装置。
此外，基座10的外周面上还可设有至少一道凸环105，用于与供电装置的外壳或支架内壁紧配合实现固定。

其中，凹槽201自基座20的底面向基座20的顶面方向延伸，不贯穿基座20的顶面，使基座20的顶面形成有一密封在凹槽201上的薄壁层202。从基座20上看，凹槽201开口朝下，薄壁层202也构成凹槽201的顶端。
薄壁层202可与基座20为一体模压成型的一体结构，其在厚度方面较基座20的其他部分小，可薄至接近或等于薄膜的厚度，从而可以发生形变及复原。
薄壁层202的厚度可为0.05±0.02mm。
本实施例中，基座20的外周形状为圆形，凹槽201、薄壁层202的形状也分别为圆形。该实施例的基座20适用于圆柱状的供电装置。
如图4、5所示，本发明一实施例的电子烟，包括相接的供电装置1和雾化装置2、配合在雾化装置2远离供电装置1的一端上的吸嘴3。电子烟还包括外壳4，供电装置1和雾化装置2装配在外壳3内，吸嘴3以其端部周缘与外壳4相接为一体。
其中，供电装置1包括呈框形的支架11、设置在支架11内的电池12、气流开关组件13和控制组件14。气流开关组件13和控制组件14分别位于电池12的相对两端并均与电池12电连接。气流开关组件13位于电池12朝向雾化装置1的一端，用于与雾化装置1连接导通；控制组件14位于电池12背向雾化装置1的另一端，处于电子烟的底部。
气流开关组件13包括转接板（PCBA板）131、气流开关132以及气流开关支架133；转接板131与电池12电连接。气流开关支架133结构可以是上述第一实施例或第二实施例的气流开关支架。
本实施例中，以图1、2所示第一实施例的气流开关支架为例对气流开关组件13进行说明：气流开关132连接在转接板131上且容置在气流开关支架133的基座10的凹槽101上，且气流开关132的外周与凹槽101的内周密封配合。
气流开关组件13还包括两个连接在转接板131上的电极134，两个电极134穿进基座10的电极槽102内且顶部穿出与电极槽103连通的电极孔104。穿出电极孔104的电极134顶部用于与雾化装置2的导体25电连接，实现雾化装置2和供电装置1之间的导通。电极134可采用弹性电极134，可保持与导体25的接触电连接。
雾化装置2可通过卡扣或磁吸等方式与供电装置1连接在一起。
雾化装置2采用现有技术的雾化装置即可，例如其可包括壳体21、设置在壳体21内的导气管22、设置在壳体21一端的雾化座23、设置在雾化座23上的发热组件24及导体25等。壳体21内设有用于储存烟液的储液仓211，导气管22穿插在壳体21的中部，储液仓211位于导气管22的外围。
壳体21的另一端上设有出气孔与导气管22内部通道相连通，雾化装置的壳体21的侧面或者雾化装置2与供电装置1的连接处设有进气孔，进气孔还贯穿外壳4至其外侧，与外部空气连通。进气孔、导气管22内部通道、出气孔和吸嘴3依次连通形成气流通道。气流通道经过气流开关支架133上薄壁层102的上方，通过进气孔进入雾化装置2内的气流，经过气流开关组件13的薄壁层102上方使其发生形变，使气流开关组件13内产生负压而控制气流开关132的启闭。
结合图2、图5，采用本发明的电子烟在吸烟时，气流从进气孔进入气流通道，经过雾化装置1底部和薄壁层102表面，薄壁层102发生形变，产生负压启动气流开关132，供电装置1给雾化装置2供电，发热组件24通电后发热将烟液雾化形成烟雾，烟雾沿着气流通道从吸嘴被使用者吸入口中。当使用者停止抽烟时，没有气流经过薄壁层102表面，薄壁层102恢复原状，薄壁层102与气流开关132之间的压力恢复原状，气流开关132断开，供电装置1停止给雾化装置2供电。
本发明的电子烟，因薄壁层102上没有孔，所以可以有效防止雾化装置2在工作过程产生的冷凝液或漏液传导到气流开关组件13上，避免造成转接板131或电池12污染，增加电子烟的使用寿命和安全性能。
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。
