【具体实施方式】
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请一部分实施例，而不是 全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，均属于本申请保护的范围。
请参阅图1至图4，图1是本申请的雾化器一实施例的立体结构示意图；图2是本申请的雾化器一实施例的剖面结构示意图；图3是图2中A部分的放大示意图；图4是本申请的雾化器一实施例的局部爆炸结构示意图。
如图1和图2所示，本申请实施例提供了一种雾化器100，其包括壳体110、储液腔120、雾化组件130和密封件140。其中，壳体110包括用于进气的进气端112和用于出气的出气端111，壳体110内部设有贯通进气端112和出气端111的第一气流通道113。储液腔120设置于壳体110内，用于储存气溶胶生成基质。雾化组件130设置于第一气流通道113，并与储液腔120流体连通，以将气溶胶生成基质雾化。密封件140具有密封件主体141和补气阀142，密封件主体141用于在壳体110和雾化组件130之间形成密封，增强雾化组件130与壳体110装配的气密性。补气阀142为单向阀，且补气阀142包括相对设置的第一侧1421和第二侧1422，第一侧1421与储液腔120相通，第二侧1422直接或间接连通外部气体。
上述的雾化器100在使用过程中，当第二侧1422的外部气体压强大于第一侧1421的储液腔120内压强，且压强差达到可推动补气阀142转动的阈值时，补气阀142打开，外部气体通过补气阀142进入储液腔120内，补充储液腔120内的气压，避免出现储液腔120内气压过低，液体无法渗透至雾化组件130进行雾化的情况，提高雾化供液的流畅度，避免出现供液不畅导致雾化组件130干烧过热的情况。需要说明的是，补气阀142为单向阀，正常情况下，储液腔120内的压强大于或等于外部气体的压强，储液腔120供液顺畅，补气阀142处于关闭状态，阻止储液腔120内的气溶胶生成基质从补气阀142处泄漏。
其中，密封件主体141为密封硅胶件144，补气阀142为弹性件143，补气阀142与密封件主体141一体成型，从而密封件主体141与雾化组件130装配更方便。
具体地，当补气阀142第二侧1422的外部气体压强比补气阀142第一侧1421的储液腔120内压强大200～2000pa时，补气阀142打开，例如200pa、600pa、1000pa、1500pa或者2000pa等。优选地，当补气阀142第二侧1422的外部气体压强比补气阀142第一侧1421的储液腔120内压强大600～1500pa时，补气阀142打开，例如600pa、900pa、1000pa或者1500pa等。
在一实施例中，如图2至图4所示，雾化组件130包括雾化座131，雾化座131外壁设有凹槽1315，凹槽1315与外部气体连通，并延伸至储液腔120，以供外部气体进入储液腔120。密封件主体141为密封硅胶件144，密封硅胶件144套设于雾化座131外。密封硅胶件144与凹槽1315间形成供外部气体进入储液腔120的换气通道150，换气通道150朝向储液腔120一端为出气口151。弹性件143位于雾化座131朝向储液腔120一侧，并覆盖于出气口151处。弹性件143包括连接于密封硅胶件144的第一端1431和与第一端1431相对的第二端1432，当弹性件143背向储液腔120的一侧的压强大于面向储液腔120一侧的压强，且压强差达到可推动弹性件143转动的阈值时，弹性件143的第二端1432朝向储液腔120内转动，从而供外部气体可从出气口151处进入储液腔120。
在一实施例中，如图2所示，雾化组件130还包括雾化元件132和雾化腔133，雾化元件132安装于雾化座131，雾化腔133设置于雾化元件132内，雾化元件132将储液腔120内储存的气溶胶生成基质在雾化腔133内雾化。
弹性件143有多种设置方式，弹性件143可以与雾化器100的中心轴垂直设置，或者弹性件143与雾化器100的中心轴平行设置。在一实施例中，如图4所示，出气口151位于雾化座131顶部，即雾化座131朝向储液腔120一侧，出气口151所在平面与雾化器100的中心轴线垂直。在自然状态下，弹性件143水平贴合于出气口151处的雾化座131顶部，弹性件143的宽度大于出气口151的宽度，弹性件143贴合于雾化座131顶部。当换气通道150内外部气体的压强大于储液腔120内的压强，且压强差达到可推动弹性件143转动的阈值时，弹性件143向上转动，换气通道150内的外部气体通过出气口151，向上进入储液腔120内，以补充储液腔120内的气压。当储液腔120内的压强大于等于换气通道150内的外部压强时，弹性件143在自上而下的气压作用下，紧密贴合于雾化座131顶部的出气口151处，防止储液腔120内的气溶胶生成基质发生泄漏。
为了控制弹性件143的弹力范围，使其更易在换气通道150内外部气体的压强大于储液腔120内的压强时向上转动，如图3所示，弹性件143的第一端1431的厚度小于弹性件143的第二端1432的厚度，弹性件143的第一端1431的宽度小于弹性件143的第二端1432的宽度，从而弹性件143更能敏锐感知其两侧压强变化，在储液腔120内压强不足时，更易向储液腔120一侧转动，及时为储液腔120内补充外部气体。具体地，可根据储液腔120内的气溶胶生成 基质的密度、雾化组件130的吸液能力等综合考虑弹性件143的弹力范围，进而对弹性件143的第一端1431的厚度和宽度进行调整，使其弹力范围适宜。
请参阅图5至图7，图5是本申请的雾化器又一实施例的剖面结构示意图；图6是图5中B部分的放大示意图；图7是本申请的雾化器又一实施例的局部爆炸结构示意图。
在此实施例中，雾化器100的结构及外部气体进入储液腔120的路径与上述图1至图3所示的实施例大致相同，如图5至图7所示，出气口151位于雾化座131顶部，在自然状态下，弹性件143水平贴合于出气口151处的雾化座131顶部。不同之处在于，由于弹性件143为橡胶弹性件，雾化器100进一步包括阻挡部以限定弹性件143打开的幅度。具体地，阻挡部160包括设置于壳体110内壁的第一台阶面114，第一台阶面114抵设于弹性件143的第一端1431的上表面，弹性件143的第一端1431位于雾化座131和第一台阶面114之间。由于弹性件143为弹性材质，例如硅胶材质，弹性件143容易出现翘边的情况，而本申请的弹性件143的第一端1431位于雾化座131和第一台阶面114之间，第一台阶面114可以压住弹性件143的第一端1431，其不会影响弹性件143储液腔120内转动，同时，可以对弹性件143的打开范围起到一定限制作用，避免弹性件143在竖直方向上转动过度，从而防止弹性件143出现变形、翘边的情况。进一步地，第一台阶面114可提高密封硅胶件144的安装便捷性，方便密封硅胶件144的快速定位及安装。
除此之外，弹性件143在安装后，容易出现水平方向的偏移，导致弹性件143不能完全覆盖出气口151，导致弹性件143的密封作用失效。从而，如图5所示，雾化座131顶部设有承托部1313，承托部1313的中部凹陷形成容纳弹性件143的容置腔1314，容置腔1314起到对弹性件143的限位作用，可避免弹性件143发生水平方向的偏移，维持弹性件143的密封作用。
进一步地，容置腔1314的宽度大于弹性件143的宽度，即承托部1313与弹性件143之间留有一定的间隙，可避免承托部1313与弹性件143之间存在摩擦，保证弹性件143在换气通道150内外部气体的压强大于储液腔120内的压强时，弹性件143可以顺利向储液腔120内转动。
请参阅图8至图12，图8是本申请的雾化器又一实施例的剖面结构示意图；图9是本申请的雾化器又一实施例的局部爆炸结构示意图；图10是本申请的雾 化器又一实施例的局部剖视结构示意图；图11是本申请的雾化器一实施例的雾化座的整体结构示意图；图12是本申请的雾化器一实施例的雾化座的另一视角的整体结构示意图。
在此实施例中，雾化器100的结构及外部气体进入储液腔120的路径与上述图1至图5所示的实施例大致相同，不同之处在于，弹性件143与雾化器100的中心轴平行设置，具体地，如图8至图11所示，出气口151竖直设置于雾化座131内部；在自然状态下，弹性件143竖直贴合于出气口151处的雾化座131内壁。
具体地，如图8和图11所示，雾化座131沿其中心轴方向向雾化座131内部开设有竖直槽1311，竖直槽1311顶部与储液腔120连通，竖直槽1311包括第一侧壁1312和与第一侧壁1312相对的第二侧壁1313，换气通道150的出气口151位于第一侧壁1312。当换气通道150内外部气体的压强大于储液腔120内的压强，且压强差达到可推动弹性件143转动的阈值时，弹性件143向竖直槽1311内转动，换气通道150内的外部气体通过出气口151进入竖直槽1311，进而进入储液腔120内，以补充储液腔120内的气压。当储液腔120内的压强大于等于换气通道150内的外部压强时，弹性件143在储液腔120内高压强的作用下，紧密贴合于竖直槽1311的出气口151处，防止储液腔120内的气溶胶生成基质发生泄漏。
由于弹性件143位于竖直槽1311内，竖直槽1311可对弹性件143起到限位作用，避免弹性件143发生偏移而不能完全覆盖出气口151，从而维持弹性件143的密封作用。进一步地，本实施例中的阻挡部160为第二侧壁1313，由于弹性件143贴合于第一侧壁1312，第一侧壁1312和第二侧壁1313间的距离大于弹性件143的厚度，且小于弹性件143的长度。弹性件143向第二侧壁1313转动的幅度，与换气通道150内外部气体和储液腔120内的压强差有关，压强差越大，弹性件143转动的幅度越大，第二侧壁1313可对弹性件143的打开范围起到一定限制作用，避免弹性件143在竖直方向上转动过度，从而防止弹性件143出现变形、翘边的情况。
需要说明的是，第一侧壁1312与第二侧壁1313间的距离可根据弹性件143的弹性能力、弹性件143的第一端1431至第二端1432的长度进行调整，使得弹性件143既能向第二侧壁1313转动，以供外部气体通过出气口151进入竖直槽1311，同时避免弹性件143在竖直方向上转动过度，从而防止弹性件143出 现变形、翘边的情况。
在一个实施例，换气通道150与雾化腔133连通。具体地，如图11和图12所示，雾化座131外壁设有若干翅片1316，若干翅片1316平行间隔设置，相邻翅片1316之间形成横向毛细槽1317，雾化座131还具有至少一纵向通气槽1318，纵向通气槽1318连通各横向毛细槽1317。雾化座131设有至少一个连通雾化腔133的通气孔1319。横向毛细槽1317具有吸液和通气的作用。
雾化腔133的气体从通气孔1319进入横向毛细槽1317或者纵向通气槽1318，随后汇聚至换气通道150，并经过补气阀142打开的出气口151进入储液腔120，以补充储液腔120内的压强。
当补气阀142打开关闭的过程中，液体可能从雾化座131顶部的出气口151溢出时，横向毛细槽可以吸收溢出的液体并进行锁液。
在其他实施例中，换气通道150可以直接与外部大气连通，例如通过在壳体110上设置换气口，换气通道150通过与换气口连通，进而直接与外部大气连通，外部气体通过换气口进入换气通道150，随后经过补气阀142打开的出气口151进入储液腔120，以补充储液腔120内的压强。
当然，在其他实施例中，换气通道150可以与雾化腔133连通，并同时与外部大气直接连通，以实现为储液腔120补充压强。
需要说明的是，上述外部气体与储液腔120连通的具体细节也适用于上述任一实施例中。请参阅图13，图13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，电子雾化装置200包括电源组件(图未示，位于电子雾化装置200内部)和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210用于为所述雾化器100进行供电，以使得所述雾化器100能够将气溶胶生成基质雾化成烟雾。
综上所述，本申请的电子雾化装置200在使用过程中，当第二侧1422的外部气体压强大于第一侧1421的储液腔120内压强，且压强差达到可推动弹性件143转动的阈值时，补气阀142打开，外部气体通过补气阀142进入储液腔120内，补充储液腔120内的气压，避免出现储液腔120内气压过低，液体无法渗透至雾化组件130进行雾化的情况，提高雾化供液的流畅度，避免出现供液不畅导致雾化组件130干烧过热的情况。正常情况下，储液腔120内的压强大于或等于外部气体的压强，储液腔120供液顺畅，补气阀142处于关闭状态，防 止储液腔120内的气溶胶生成基质从补气阀142处泄漏。
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。
