本申请一实施例提供了一种雾化器100，如图1和图2所示，包括壳体110、气流通道120、储液仓130、雾化组件140和进气阀150。壳体110开设有进气口111和出气口112，气流通道120形成于壳体110内部，并贯通进气口111和出气口112；储液仓130设置于壳体110内，储存供雾化组件140雾化使用的原料流体，例如烟油；雾化组件140设置于气流通道120，并与储液仓130流体连通，从而储液仓130内的流体可供应至雾化组件140，由雾化组件140雾化。抽吸过程中，外部气体从进气口111进入，在气流通道120内携带由雾化组件140雾化后的雾气后再由出气口112流出。
其中，进气阀150设置于进气口111至雾化组件140之间的气流通道120内，进气阀150的出气部靠近雾化组件140，进气阀150的进气部远离雾化组件140，进气阀150与雾化组件140之间形成储存漏液的储漏区域151。不使用时，由于气流通道120内的压力比外界压力大或相等，进气阀150可在压力差或自身弹性力的作用下保持密闭，即使储液仓130内的流体透过雾化组件140发生泄漏，也不会从进气阀150处泄漏，而是积存在储漏区域151内，避免了漏液从进气口111处泄漏后污染其他元件、造成损坏。除此之外，当抽吸完毕后，由于气流通道120内压力增大，会发生雾气回流的情况，在没有进气阀150的情况下，雾气穿过进气口111，遇到雾化器100的外壁，会冷凝成液，进气阀150可以防止雾气回流的情况发生。
在一实施例中，如图2所示，壳体110包括安装座113，安装座113用于支撑雾化组件140，并且限定进气口111，进气口111与出气口112分别位于壳体110的两端。其中，雾化组件140包括雾化芯141，由安装座113支撑固定在壳体110内，且其一部分位于气流通道120内，另一部分位于储液仓130内。雾化芯141可为多孔陶瓷体，外围包裹有一层导液棉，导液棉从储液仓130吸收流体，供雾化使用。
在一实施例中，如图2所示，使用雾化器100时，由于使用者在出气口112处抽吸，气流通道120内压力降低，进气阀150进气部的压强比出气部一侧的气流通道120内的压强大至少100pa时，进气阀150打开，外部的气体通过进气阀150进入气流通道120内。需要说明的是，进气阀150打开所需的两侧压强差还可以是200pa，500pa，1000pa，1500pa，2000pa或者更高，进气阀150打开所需的压强差取决于进气阀150的结构和材料，当进气阀150打开所需进气阀150进气部的压强比出气部一侧的气流通道120内的压强大100pa～2000pa时，进气阀150不仅能具有较好的防漏效果，而且使用者能较为轻松地进行抽吸。
在一实施例中，如图3所示，雾化器100还包括补气阀160，补气阀160设置于壳体110，补气阀160的出气部位于储液仓130内，补气阀160的进气部与外部大气连通。正常使用情况下，储液仓130内的气压比外界大气气压大或相等，补气阀160可在压力差或自身弹性力的作用下保持密闭，防止储液仓130内的流体通过补气阀160泄漏。随着储液仓130内的流体不断通过雾化组件140雾化消耗后，储液仓130内的气压降低，当补气阀160的进气部一侧压强比储液仓130内压强大至少100pa时，补气阀160打开，外界空气进入储液仓130内，补充储液仓130内的气压，避免出现储液仓130内气压过低，流体无法渗透至雾化组件140进行雾化的情况，提高雾化下液的流畅度。需要说明的是，补气阀160打开所需的两侧压强差还可以是200pa，500pa，1000pa，1500pa，2000pa或者更高，补气阀160打开所需的压强差取决于补气阀160的结构和材料，当补气阀160打开所需补气阀160进气部侧的大气压强比出气部一侧的储液仓130内的压强大100pa～2000pa时，补气阀160能及时补充储液仓130内的气压，保持储液仓130雾化下液的流畅度。
在一实施例中，如图3所示，补气阀160具有三个，其中，一个补气阀160位于壳体110上设有出气口112的第一端；一个补气阀160位于壳体110上设有进气口111的第二端；一个补气阀160位于壳体110上的第一端和第二端之间的侧壁上。在其他实施例中，补气阀160可以仅设置有一个，且可位于上述三个位置中的任一位置。或者，在其他实施例中，补气阀160还可以有二个、四个或者更多个，此处不作限定。
进一步地，如图3所示，雾化器100还包括吸嘴阀170，吸嘴阀170设置于气流通道120内，且位于出气口112和雾化组件140之间，吸嘴阀170的出气 部朝向出气口112，吸嘴阀170的进气口111朝向雾化组件140。在使用者抽吸过程中，吸嘴阀170打开，雾化后的雾气可经吸嘴阀170从出气口112流出，抽吸完毕后，吸嘴阀170在自身弹性力的作用下闭合，进一步防止漏液从出气口112处流出。当吸嘴阀170的进气部一侧的压强比吸嘴阀170的出气部一侧的外部压强大至少100pa时，吸嘴阀170打开，需要说明的是，吸嘴阀170打开所需的两侧压强差还可以是200pa，500pa，1000pa，1500pa，2000pa或者更高，吸嘴阀170打开所需的压强差取决于吸嘴阀170的结构和材料，当吸嘴阀170打开所需吸嘴阀170进气部侧的压强比出气部一侧的外部压强大100pa～2000pa时，吸嘴阀170不仅能具有较好的防漏效果，而且使用者能较为轻松地进行抽吸。
在一实施例中，如图3和4所示，进气阀150、补气阀160和吸嘴阀170均为单向阀180，单向阀180包括底座181和变形壁182。底座181开设有贯通口(图未示)，变形壁182设置于贯通口上，变形壁182设置有切口1851，变形壁182与贯通口相连一侧形成进气部183，切口1851处形成出气部184。在正常情况下，切口1851处封闭；在变形壁182的进气部183压强比出气部184压强大至可使得变形壁182变形时，切口1851处打开，单向阀180进行通气。
具体地，如图4所示，单向阀180的变形壁182包括两个第一变形壁，两个第一变形壁由贯通口向外逐渐靠拢形成条形末端185，并在条形末端185形成细长状的切口1851。
在其他实施例中，请参阅图5至图9，单向阀180可有多种结构，具体如下文所述。
如图5所示，单向阀180的变形壁182可以为圆筒形，变形壁182由贯通口向外延伸后闭合形成半球形末端185，并在半球形末端185形成十字形的切口1851，其中，圆筒形处的变形壁182为可变形或不可变形的材料均可，半球形末端185为可变形材料。
如图6所示，单向阀180的变形壁182为圆筒形，变形壁182由贯通口处向外延伸后闭合形成平面末端185，并在平面末端185形成两个弧形的切口1851，切口1851为劣弧形，其中，圆筒形处的变形壁182为可变形或不可变形的材料均可，平面末端185为可变形材料。
如图7和图8所示，单向阀180的变形壁182为圆筒形，变形壁182由贯通口处向外延伸后闭合形成平面末端185，并在平面末端185形成一个弧形的切 口1851，切口1851为优弧形，变形壁182内部设置有支撑平面末端185的支撑件1822，防止其向进气部183一侧打开。其中，圆筒形处的变形壁182为可变形或不可变形的材料均可，平面末端185为可变形材料。
如图9所示，单向阀180的变形壁182为圆筒形，变形壁182由贯通口处向外延伸后闭合形成平面末端185，并在侧壁形成一弧形的切口1851。
可根据实际需求或者使用条件选择上述不同结构的单向阀180。
请参阅图10，图10是本申请的电子雾化装置一实施例的立体结构示意图。
本申请又一实施例提供了一种电子雾化装置200，包括上述任一实施例中的雾化器100。电子雾化装置200还包括电源组件，电源组件用于为所述雾化器100进行供电，以使得所述雾化器100能够将气雾生成基质雾化成烟雾。
综上所述，本申请的雾化器100通过在进气口111至雾化组件140之间的气流通道120内设置进气阀150，进气阀150与雾化组件140之间形成储存漏液的储漏区域151，即使储液仓130内的流体透过雾化组件140发生泄漏，也不会从进气阀150处泄漏，而是积存在储漏区域151内，避免了漏液从进气口111处泄漏后污染其他元件、造成损坏；当抽吸完毕后，进气阀150可以防止雾气回流的情况发生。本申请的雾化器100还通过在壳体110设置补气阀160，正常使用情况下，储液仓130内的气压比外界大气气压大或相等，补气阀160可在压力差或自身弹性力的作用下保持密闭，防止储液仓130内的流体通过补气阀160泄漏，在储液仓130内气压不足时，补气阀160能及时补充储液仓130内的气压，保持储液仓130雾化下液的流畅度。
以上所述仅为本申请的实施例，并非因此限制本申请的专利范围，凡是利用本申请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它相关的技术领域，均同理包括在本申请的专利保护范围内。
