需要说明的是，本申请定义子储液腔101位于发热体13的上方的状态为雾化器1为正置，子储液腔101位于发热体13的下方的状态为雾化器1为倒置。本实施例中，抽吸口1111朝上时，雾化器1为正置，子储液腔101位于发热体13的上方；抽吸口1111朝下时，雾化器1为倒置，子储液腔101位于发热体13的下方。
在本实施例中，发热体13为片状，发热体13包括导液基体(图未标)和发热元件(图未标)，发热元件设于导液基体的表面，导液基体用于导引气溶胶生成基质，发热元件用于雾化气溶胶生成基质。导液基体的材料可以为多孔陶瓷，也可以为致密材料；当导液基体的材料为致密材料，可以为石英、玻璃、致密陶瓷或硅。在其他实施例中，发热体13可以为现有的多孔陶瓷发热体或棉芯发热体，具体根据需要进行设计。发热体13实际用作雾化器1的雾化芯。可以理解，除了采用发热体作为雾化芯，雾化器1也可以采用其他类型的雾化芯，例如超声振动雾化片等，在此不做限定。
可以理解，在本实施例中，雾化座12由顶座121和底座122上下装配形成；在其他实施例中，雾化座12也可以由两个结构件左右装配形成，具体根据需要进行设计。也就是说，本申请并不限定雾化座12的结构，仅以顶座121和底座122形成的雾化座12为例对出液孔1211的具体设置进行详细介绍。
请参阅图3-图5，图3是图2提供的雾化器的壳体的仰视结构示意图，图4是图2提供的雾化器另一角度的结构示意图，图5是图2提供的雾化器的储液腔、出液孔以及锁液腔连接后的简易结构示意图。
壳体11的内部具有隔片112，隔片112的长度方向与雾化器1的轴向方向相同，隔片112将储液腔10分隔为多个子储液腔101。在本实施例中，多个子储液腔101的数量为两个，隔片112将储液腔10分隔为两个子储液腔101；具体地，壳体11具有两个隔片112，两个隔片112分别设置于出雾通道111的相对两侧，隔片112的一侧与出雾通道111的外表面连 接，隔片112的另一侧与壳体11的内表面连接，隔片112将壳体11与顶座121围设形成的空间分隔成相互独立的两个子储液腔101。顶座121上设有两个出液孔1211，一个出液孔1211与一个子储液腔101连通，另一个出液孔1211与另一个子储液腔101连通；即，两个出液孔1211与两个子储液腔101一一对应连通。可选的，壳体11一体成型有外壳(图未标)、中心出气管(图未标)及隔片112，隔片112连接外壳和中心出气管，起到加强肋的作用；其中，外壳用于与雾化座12配合形成储液腔10，中心出气管形成出雾通道111。
本实施例中，两个隔片112共面设置且两个隔片112所在的平面垂直于雾化器1的宽度方向。在其他实施例中，也可以不设置隔片112，将壳体11的内表面与出雾通道111的外表面相切并连接，从而将壳体11与顶座121围设形成的空间分隔成相互独立的两个子储液腔101。
雾化器1还包括密封件14，密封件14套设于顶座121的表面，用于防止漏液。密封件14设于顶座121的顶面和侧面，隔片112与密封件14位于顶座121的顶面的部分抵接，以将两个子储液腔101完全分隔开来，即，两个子储液腔101为相互独立的空腔。可以理解，当顶座121上并未设置用于密封的密封件14时，隔片112与顶座121抵接，以将两个子储液腔101完全分隔开来。密封件14位于顶座121的顶面的部分设有第一贯穿孔(图未标)，第一贯穿孔对应于顶座121上的出液孔1211和出雾孔1210设置，以使出液孔1211和出雾孔1210露出，实现出液孔1211与储液腔10连通，出雾孔1210与出雾通道111连通。
发热体13与顶座121配合形成锁液腔130，两个出液孔1211分别与锁液腔130连通。也就是说，两个子储液腔101位于锁液腔130的上方，发热体13直接与锁液腔130导液连通。其中，顶座121靠近底座122的一端具有台阶槽(图未标)，台阶槽包括靠近出液孔1211的第一凹槽(图未标)和远离出液孔1211的第二凹槽(图未标)；第二凹槽的尺寸大于第一凹槽的尺寸；发热体13设置于第二凹槽内并覆盖第一凹槽，发热体13与第一凹槽配合形成锁液腔130。抽吸口1111和所有子储液腔101位于锁液腔130的同一侧。
本申请的出液孔1211位于锁液腔130与子储液腔101之间，并流体连通锁液腔130与子储液腔101。出液孔1211靠近子储液腔101的端口为出液口1211a。需要说明的是，当出液孔1211的长度很短的情况下，可以认为出液孔1211即为出液口1211a。
当子储液腔101位于锁液腔130上方时，子储液腔101内的气溶胶生成基质经出液孔1211进入锁液腔130；当子储液腔101位于锁液腔130下方时，气溶胶生成基质在出液口1211a形成液膜，液膜将锁液腔130和出液孔1211内的气溶胶生成基质封锁在锁液腔130和出液孔1211内。可以理解，本申请中，形成子储液腔101、出液孔1211和锁液腔130的方式不限于上述方式。
具体地，每个子储液腔101与锁液腔130之间仅通过一个出液孔1211流体连通。一个出液孔可以为单一的通孔，也可以包括多个当量直径总和与该单一的通孔的当量直径相同的子通孔。
为了在雾化器1倒置过程中，使气溶胶生成基质在出液口1211a容易形成液膜，且液膜能够保持稳定并将锁液腔130和出液孔1211内的气溶胶生成基质封锁在锁液腔130和出液孔1211内，本申请中，出液孔1211的壁面与出液口1211a周边的壁面形成的角度β不小于240°，且出液口1211a的孔径r满足公式：r<2σcosθ/ρgh，其中，σ为气溶胶生成基质的表面张力系数，ρ为气溶胶生成基质的密度，g为重力加速度，θ为气溶胶生成基质与出液孔1211靠近出液口1211a处的壁面的接触角，h为液膜上方的气溶胶生成基质的高度。对于非圆形出液口1211a，出液口1211a的孔径r为出液口1211a的当量半径。
可以理解，如果出液孔1211的壁面与出液口1211a周边的壁面形成的角度β小于240°，子储液腔101位于锁液腔130上方时，子储液腔101内的气溶胶生成基质更容易浸润到出液孔1211内，同理，当子储液腔101位于锁液腔130下方时，出液孔1211内的气溶胶生成基质也更容易浸润到子储液腔101内。因此，在雾化器1倒置的过程中，出液孔1211内的气溶胶生成基质不容易与子储液腔101内的气溶胶生成基质断开，即，出液孔1211内的气溶胶生成基质不容易形成液膜。优选，出液孔1211的壁面与出液口1211a周边的壁面形成的角度β大于270°，有利于出液孔1211内的气溶胶生成基质与子储液腔101内的气溶胶生成基质在出液口1211a处断开，从而将出液孔1211内的气溶胶生成基质液膜封在出液孔1211内。如果出液口1211a的孔径r太大，气溶胶生成基质在出液口1211a形成的液膜的表面张力会太小，该表面张力不足以将锁液腔130和出液孔1211内的气溶胶生成基质封锁在 锁液腔130和出液孔1211内。
当雾化器1仅有一个子储液腔101和一个锁液腔130时，出液口1211a的孔径r满足公式r<2σcosθ/ρgh，即可将锁液腔130和出液孔1211内的气溶胶生成基质封锁在锁液腔130和出液孔1211内。
当雾化器1包括多个子储液腔101且多个子储液腔101流体连通到同一个锁液腔130时，为了确保锁液腔130和出液孔1211内的气溶胶生成基质不会突破液膜，需要确保多个子储液腔101内的气压基本稳定，即多个子储液腔101位于锁液腔130下方时，多个子储液腔101内的气体和/或气溶胶生成基质不串流。因此，多个子储液腔101之间相互独立设置。
具体地，多个子储液腔101之间相互独立设置可以为：多个子储液腔101之间彼此物理隔离，仅通过出液孔1211和锁液腔130连通(如图5所示)；或多个子储液腔101之间彼此物理隔离，除通过出液孔1211和锁液腔130连通之外，仅通过具有锁液功能的微通道102连通(如图12所示)。
具体地，如图5中所示的N区域，出液孔1211与子储液腔101的连接处形成截面突变结构。通过突变结构使得出液孔1211的壁面与出液口1211a周边的壁面形成的角度β不小于240°，且出液口1211a的孔径r满足公式：r<2σcosθ/ρgh。
当雾化器1倾斜倒置，使得两个子储液腔101位于锁液腔130的下方时，截面突变结构使出液孔1211内的气溶胶生成基质形成液膜，将锁液腔130的气溶胶生成基质封锁在锁液腔130内。换句话说，在出液孔1211靠近子储液腔101的出液口1211a形成液膜，该液膜具有的表面张力封锁出液孔1211和锁液腔130内的气溶胶生成基质；截面突变结构在出液孔1211侧形成的液膜的表面张力与其对应的子储液腔101的气体压力之和为第一值，出液孔1211和锁液腔130内的气溶胶生成基质在出液孔1211靠近子储液腔101的端口的压力为第二值，第一值大于第二值，实现锁液。可以理解，由于锁液腔130是由发热体13与顶座121配合形成的，两个子储液腔101位于锁液腔130的下方，两个子储液腔101也就位于发热体13的下方，雾化器1为倒置的。
本实施例中，两个子储液腔101、两个出液孔1211以及锁液腔130形成U型结构。具体地，两个子储液腔101分别为第一子储液腔101、第二子储液腔101；两个出液孔1211分别为第一出液孔1211和第二出液孔1211，第一子储液腔101、第一出液孔1211、锁液腔130、第二出液孔1211以及第二子储液腔101依次连接形成U形结构。两个子储液腔101位于锁液腔130下方时，两个子储液腔101之间的气体和/或气溶胶生成基质不串流。
继续参见图5和图2，两个子储液腔101的出液孔1211的截面突变结构在雾化器1的中轴线上的同一高度位置，即两个子储液腔101的出液口1211a在雾化器1的中轴线上的同一高度位置，使得两个子储液腔101内的气压基本相同，利于保持锁液后的平衡。
请参阅图6和图7，图6是现有技术中雾化器的储液腔、出液孔以及锁液腔连接后的简易结构示意图，图7是现有技术中雾化器的储液腔、出液孔以及锁液腔连接后的结构在倾斜过程中气液流动示意图。
现有的储液腔包括两个子储液腔201以及连通两个子储液腔201的连通储液腔202。两个出液孔203的一端分别与连通储液腔202连通，两个出液孔203的另一端分别与锁液腔204连通。锁液腔204直接与发热体205流体连通。
现有雾化器在初始状态下，即雾化器朝上，且发热体205位于子储液腔201下方，两个子储液腔201内的空气压力分别为P A、P B，在雾化器倾斜或翻转时，子储液腔201内的气溶胶生成基质在重力作用下会流向相对位置更低的区域，从而导致两个子储液腔201之间的气压平衡被破坏，失衡的气体压力通过连通储液腔202进行流通，如此往复，最终在雾化器倒置状态下，即雾化器朝下，发热体205位于子储液腔201上方，气溶胶生成基质将全部汇聚到下方区域，发热体205所在的上方区域无法存储气溶胶生成基质，从而造成发热体205干烧。
请参阅图8，图8是图2提供的雾化器的储液腔、出液孔以及锁液腔连接后的结构在倾斜过程中气液流动示意图。
而本申请通过将第一子储液腔101、第一出液孔1211、锁液腔130、第二出液孔1211以及第二子储液腔101依次连接形成U形结构，雾化器1在倾斜或翻转的过程中，两个子储液腔101内的气体无法突破出液孔1211靠近子储液腔101的端口形成的液膜的表面张力，无法实现两个子储液腔101之间的气体流通，两个子储液腔101内的液位产生的压力差通过 两个子储液腔101内的气体的膨胀和压缩来平衡。雾化器1倾斜或翻转时，两个子储液腔101内的气溶胶生成基质在重力作用下向远离发热体13的方向流动，即流动至储液腔10的下方；由于两个子储液腔101之间无法实现气体流通，两个子储液腔101内的气溶胶生成基质和气体只能在各自区域内进行流动；也就是说，两个子储液腔101内的气体被气溶胶生成基质隔离，雾化器1倾斜或翻转过程中，两个子储液腔101内的气压基本保持不变。而其整体若要向某一侧流动，则必然受到两侧气体的阻力，因此在两个子储液腔101内气体压力的作用下，锁液腔130内的气溶胶生成基质只能滞留在锁液腔130内，以及出液孔1211内的气溶胶生成基质只能滞留在出液孔1211内，从而达到实现倾斜和倒置后在锁液腔130和出液孔1211内储液的效果，保证倒抽时的供液充足，短时间内不会出现发热体13烧焦或烧断的现象。
本申请还对U形结构的锁液能力进行了实验。实验证明，U形结构倒置放最长两天没问题，如无强烈外力震荡不会导致液体垮掉，具有较好的锁液能力。
当锁液腔130的气溶胶生成基质将U型结构的底部封堵时，在雾化器1倾斜倒置使得两个子储液腔101位于锁液腔130下方的过程中，多个子储液腔101彼此之间不串流气体和/或气溶胶生成基质。可以理解，本申请中雾化器1的倾斜倒置是指用户一般速度的倾斜倒置过程，通常1秒内完成，而不包括非常缓慢的倾斜倒置过程。
可以理解，沿着雾化器1的轴向，子储液腔101的横截面积相同；由于子储液腔101的横截面积较大，在子储液腔101内形成的液膜的表面张力较小，且整体液位高度较大，子储液腔101内形成的液膜的表面张力易突破，子储液腔101内的气溶胶生成基质可以顺畅的流至出液孔1211。由于子储液腔101内形成的液膜的表面张力较小，雾化器1旋转时，子储液腔101内形成的液膜的表面张力不足以支撑子储液腔101内的气溶胶生成基质，所以两个子储液腔101内的气溶胶生成基质在各自区域内可随意流动。
出液孔1211靠近子储液腔101的端口的截面积要小于子储液腔101的横截面积，在出液孔1211靠近子储液腔101的端口形成的液膜的表面张力较大，且出液孔1211内的气溶胶生成基质要远小于子储液腔101内的气溶胶生成基质，因此，雾化器1倒置时，出液孔1211靠近子储液腔101的端口形成的液膜的表面张力可以锁住出液孔1211和锁液腔130内的气溶胶生成基质。
在一实施方式中，截面突变结构在出液孔1211侧的当量直径为1mm-6mm，在保证下液顺畅的同时具有一定的表面张力，以使雾化器1倒置时可以通过液膜的表面张力锁住出液孔1211、锁液腔130内的气溶胶生成基质，进一步提高了锁液能力。截面突变结构在出液孔1211侧的当量直径小于1mm，从出液孔1211进入锁液腔130的下液量较少，易造成发热体13供液不足；截面突变结构在出液孔1211侧的当量直径大于6mm，在出液孔1211侧形成的液膜的表面张力太小，无法实现较好的锁液效果。示例性的，截面突变结构在出液孔1211侧的当量直径为4mm。
在一实施方式中，截面突变结构在子储液腔101侧的截面积与截面突变结构在出液孔1211侧的截面积的比大于1.2，即子储液腔101靠近出液孔1211的端口的截面积与出液孔1211靠近子储液腔101的端口的截面积的比大于1.2。可选的，截面突变结构在子储液腔101侧的截面积与截面突变结构在出液孔1211侧的截面积的比大于1.5。
在一实施方式中，出液孔1211靠近子储液腔101的端口的横截面相对其对应的子储液腔101靠近出液孔1211的端口的横截面收窄，以在出液孔1211与子储液腔101的连接处形成截面突变结构；和/或，出液孔1211靠近子储液腔101的端口的横截面形状不同于其对应的子储液腔101靠近出液孔1211的端口的横截面形状，以在出液孔1211与子储液腔101的连接处形成截面突变结构，以使出液孔1211与储液腔10的连接处存在流动状态变化。其中，出液孔1211靠近子储液腔101的端口为图4中所示A区域，子储液腔101靠近出液孔1211的端口为图4中所示B区域。
在一实施方式中，截面突变结构在子储液腔101侧与气溶胶生成基质的接触角小于截面突变结构在出液孔1211侧与气溶胶生成基质的接触角，即子储液腔101靠近出液口1211a处的壁面与气溶胶生成基质的接触角小于出液孔1211靠近出液口1211a处的壁面与气溶胶生成基质的接触角，气溶胶生成基质易在出液孔1211靠近子储液腔101的端口断开，利于在出液孔1211靠近子储液腔101的端口形成液膜，实现较好的锁液效果。
具体实施中，密封件14的材料与壳体11的材料具有不同亲液性，且密封件14设于截 面突变结构的子储液腔101侧，即，密封件14与气溶胶生成基质的表面接触角大于子储液腔101的内壁与气溶胶生成基质的表面接触角，以使在出液孔1211与子储液腔101的连接处具有与气溶胶生成基质接触角突变，气溶胶生成基质易在出液孔1211靠近子储液腔101的端口断开，利于在出液孔1211靠近子储液腔101的端口形成液膜，实现较好的锁液效果。示例性的，密封件14的材料为硅胶，壳体11的材料为塑胶；其中，硅胶与气溶胶生成基质的表面接触角大于塑胶与气溶胶生成基质的接触角。
请参阅图9a，图9a是本申请提供的雾化器第二实施例的局部结构示意图，图9b是图9a提供的雾化器的密封件与顶座的分解示意图。
雾化器1的第二实施例与雾化器1第一实施例的结构基本相同，不同之处在于：顶座121的顶面上还设有凸台1212，凸台1212沿着出液孔1211的周缘设置。
密封件14对应于出液孔1211的位置设有贯穿孔14a，凸台1212穿设于贯穿孔14a内。具体地，密封件14包括顶壁(图未标)和环形侧壁(图未标)，密封件14的顶壁设于顶座121的顶面，密封件14的环形侧壁设于顶座121的侧面；密封件14的顶壁对应于出液孔1211处设有贯穿孔14a，以使凸台1212穿过贯穿孔14a。通过上述设置，在雾化器1倾斜或翻转过程中，凸台1212围设形成的空间内的气溶胶生成基质的表面更易与壳体11内的气溶胶生成基质的表面断开，即出液孔1211内的气溶胶生成基质的表面与子储液腔101内的气溶胶生成基质的表面更易断开，这是因为壳体11的内表面与凸台1212的端口之间无法形成连续的液膜，防止凸台1212的端口形成的液膜的表面张力被破坏。可以理解，由于出液孔1211靠近储液腔的一侧的周缘设有凸台1212，通过凸台1212的端口形成的液膜的表面张力可以锁住出液孔1211和锁液腔130内的气溶胶生成基质。
可选的，凸台1212与顶座121一体成型。例如，凸台1212与顶座121的材质为塑胶。
可选的，凸台1212沿着出液孔1211的周缘一整周设置，凸台1212为环形的，凸台1212的内表面与出液孔1211的内表面齐平。凸台1212的外表面与顶座121的侧壁以及出雾孔1210均间隔设置。
请参阅图10a和图10b，图10a是本申请提供的雾化器第三实施例的局部结构示意图，图10b是图10a提供的雾化器的密封件与顶座的分解示意图。
雾化器1的第三实施例与雾化器1第一实施例的结构基本相同，不同之处在于：密封件14具有向远离顶座121方向延伸的第一凸起部142。
密封件14包括密封本体部141和第一凸起部142。密封本体部141套设于顶座121的表面，密封本体部141对应于出液孔1211的位置设有贯穿孔14a，第一凸起部142环绕贯穿孔14a且向远离顶座121的方向延伸，即，第一凸起部142向子储液腔101内延伸。其中，密封本体部141包括顶壁(图未标)和环形侧壁(图未标)，密封本体部141的环形侧壁设于顶座121的侧面，密封本体部141的顶壁设于顶座121的顶面，密封本体部141的顶壁对应于出液孔1211的位置设有贯穿孔14a。
通过上述设置，在雾化器1倾斜或翻转过程中，第一凸起部142围设形成的空间内的气溶胶生成基质的表面更易与壳体11内的气溶胶生成基质的表面断开，即第一凸起部142内的气溶胶生成基质的表面与子储液腔101内的气溶胶生成基质的表面更易断开，这是因为壳体11的内表面与第一凸起部142的端口之间无法形成连续的液膜，防止第一凸起部142的端口形成的液膜的表面张力被破坏。可以理解，由于出液孔1211靠近储液腔的一侧的周缘设有第一凸起部142，通过第一凸起部142的端口形成的液膜的表面张力可以锁住出液孔1211和锁液腔130内的气溶胶生成基质。
可选的，第一凸起部142为环绕贯穿孔14a一整周的凸环，第一凸起部142的内表面与出液孔1211的内表面齐平。第一凸起部142的外表面与顶座121的侧壁以及出雾孔1210均间隔设置。
可选的，密封件14的材质为硅胶。
需要说明的是，雾化座12的材质为塑胶。由于硅胶与气溶胶生成基质的表面接触角大于塑胶与气溶胶生成基质的接触角，使密封件14具有第一凸起部142(雾化器1的第三实施例)相对于顶座121的顶面上设置凸台1212(雾化器1的第二实施例)，雾化器1倾斜或翻转过程中，更利于阻碍与壳体11之间形成连续的液膜，更易于使气溶胶生成基质与壳体11的内表面断开。
请参阅图11a和图11b，图11a是本申请提供的雾化器第四实施例的局部结构示意图， 图11b是图11a提供的雾化器的密封件与顶座的分解示意图。
雾化器1的第四实施例与雾化器1第一实施例的结构基本相同，不同之处在于：出液孔1211的孔壁靠近储液腔10的部分设有疏液结构1213，以在出液孔1211与子储液腔101的连接处具有与气溶胶生成基质接触角突变，壳体11的内表面与疏液结构1213靠近储液腔10处无法形成连续的液膜，以使雾化器在倾斜或翻转过程中，出液孔1211内的气溶胶生成基质的表面更易与壳体11内的气溶胶生成基质的表面断开，使得疏液结构1213靠近储液腔10处形成的液膜具有的表面张力能够实现锁液功能。可选的，疏液结构1213沿着出液孔1211的孔壁的周向整周设置。也就是说，出液孔1211在靠近子储液腔101侧的内壁面与气溶胶生成基质的接触角大于出液孔1211靠近锁液腔130侧的内壁面与气溶胶生成基质的接触角；其中，疏液结构1213位于出液孔1211在靠近子储液腔101侧的内壁。
在一实施方式中，疏液结构1213为设置于出液孔1211的孔壁的涂层，涂层具有疏气溶胶生成基质的性能。
在另一实施方式中，疏液结构1213为通过对出液孔1211的孔壁进行改性处理的微结构，该微结构具有疏气溶胶生成基质的性能。
在又一实施方式中，密封件14设于顶座121的侧面和顶面，且密封件14位于顶座121的顶面的部分延伸至出液孔1211的孔壁形成疏液结构1213(如图11a和11b所示)。具体地，密封件14包括密封本体部141和第二凸起部143，密封本体部141套设于顶座121的表面，密封本体部141对应于出液孔1211的位置设有贯穿孔14a，第二凸起部143环绕贯穿孔14a且沿着出液孔1211的孔壁延伸至出液孔1211内形成疏液结构1213，第二凸起部143的长度小于出液孔1211的深度；其中，密封本体部141包括顶壁(图未标)和环形侧壁(图未标)，密封本体部141的环形侧壁设于顶座121的侧面，密封本体部141的顶壁设于顶座121的顶面，密封本体部141的顶壁对应于出液孔1211的位置设有贯穿孔14a。
可选地，第二凸起部143为环绕贯穿孔14a一整周设置的凸环。第二凸起部143的高度小于出液孔1211长度的一半。例如，第二凸起部143的高度为出液孔1211长度的五分之一到四分之一。
出液孔1211的孔壁具有多个翅片1214，多个翅片1214沿着出液孔1211的孔壁的周向间隔设置。翅片1214的长度方向与出液孔1211的轴线平行设置。每个翅片1214靠近储液腔10的端面为平面。每个翅片1214与出液孔1211靠近储液腔10的端口均间隔设置；多个翅片1214靠近储液腔10的端面与出液孔1211靠近储液腔10的端口之间的距离相同。每个翅片1214远离出液孔1211的孔壁的端面为平面。多个翅片1214的底端可以均直接设置于出液孔1211的底壁上。密封件14的第二凸起部143的端面与翅片1214靠近储液腔10的端面间隔设置或抵接。
可以理解，由于多个翅片1214之间是间隔设置的，气溶胶生成基质可以通过翅片1214之间形成的间隙具有的毛细作用力流至发热体13，进一步提高了锁液能力。
请参阅图12和图13，图12是本申请提供的雾化器第五实施例的储液腔、出液孔以及锁液腔连接后的简易结构示意图，图13是图12提供的储液腔、出液孔以及锁液腔连接后的结构在倾斜过程中气液流动示意图。
雾化器1的第五实施例与雾化器1第一实施例的结构基本相同，不同之处在于：两个子储液腔101之间除了可以通过锁液腔130连通，还可以通过一个或多个微通道102连通。通过在两个子储液腔101之间设置微通道102，将两个子储液腔101之间进行流体连通，相邻两个子储液腔101中一侧的气溶胶生成基质的液面低于微通道102时，低液位一侧的子储液腔101内的气体可以通过微通道102进入到另一侧的子储液腔101内，使得各子储液腔101内的气压相同，从而最终使得各子储液腔101内的液位高度相同。即使由于气溶胶生成基质消耗不均匀或单侧换气等原因导致了两个子储液腔101之间的液位不平衡，当相邻两个子储液腔101中有一侧的气溶胶生成基质的液面低于微通道102时，低液位一侧的子储液腔101内的气体可以突破微通道102的表面张力并进入到高液位一侧的子储液腔101内，以此可以对两个子储液腔101内的气压进行平衡，进而消除两个子储液腔101中的液位差，防止两个子储液腔101内的液位差一直增加导致低液位一侧的子储液腔101内的气溶胶生成基质被消耗完而造成雾化器1干烧。通过设置微通道102来消除各子储液腔101内气溶胶生成基质的液位差，提升雾化器1的雾化性能，进而提升用户使用体验。
可选的，微通道102的当量直径尺寸小于等于5mm，以使微通道102形成较强的毛细 作用力以实现液封。具体地，在雾化器1倾斜或翻转过程中，子储液腔101内气溶胶生成基质的液位低于微通道102的一侧或两侧时，微通道102较强的毛细作用力实现液封，避免两个子储液腔101之间的气体相互流动造成子储液腔101内的气压变化，使其与完整的U形结构具有相同的锁液效果(如图13所示)。也就是说，在不破坏U形结构的锁液功能的前提下，两个子储液腔101之间通过微通道102连通。
可选的，两个子储液腔101靠近发热体13的一端通过微通道102连通。
U型的储液结构中两个子储液腔101的两侧下液并不同步，通常是一侧的液面低至出液孔1211的底端，另一侧才开始下液；其原因主要为雾化器1设有两个独立的换气结构，一个换气结构对应一个子储液腔101设置，另一个换气结构对应另一个子储液腔101设置，以上述的两个换气结构进行换气时，气体一旦开通从一侧换气结构换气后，就习惯于从这一侧换气结构换气，另一侧基本不会换气，并且在另一侧下液的时候，依然是这一侧换气结构换气，气泡会从发热体13靠近储液腔10的表面去到另一侧通道，增大了气泡附着在发热体靠近储液腔表面的概率，易导致供液不足。由于单侧换气，导致单侧子储液腔101内的气溶胶生成基质消耗至其液位低于微通道102的出口，将两个子储液腔101靠近发热体13的一端通过微通道102连通，高液位的子储液腔101内的气溶胶生成基质可以通过微通道102进入低液位的子储液腔101，低液位的子储液腔101内的气体可以通过微通道102流向高液位的子储液腔101，防止高液位的子储液腔101进行换气时气体流经发热体13靠近储液腔10的表面，避免了气泡粘附在发热体13靠近储液腔10的表面，利于保证供液充足。
可选的，微通道102为设置在隔片112靠近顶座121一端的通孔或者缺口，通孔或者缺口的端口尺寸小于等于5mm。
可选的，隔片112靠近顶座121一端的端面与密封件14之间间隔设置，在形成相互独立的两个子储液腔101的同时形成微通道102(如图14所示，图14是本申请提供的雾化器第五实施例的结构示意图)。密封件14与隔片112之间的间隔距离小于等于5mm。示例性的，密封件14与隔片112之间的间隔距离为1mm。
请参阅图15-图17，图15是本申请提供的雾化器第六实施例的结构示意图，图16是图15提供的雾化器的顶座的结构示意图，图17是图16提供的顶座的局部放大结构示意图。
雾化器1的第六实施例与雾化器1第一实施例的结构基本相同，不同之处在于：在两个子储液腔101的相邻处设置换气槽1215，换气槽1215分别与两个子储液腔101连通，以对两个子储液腔101进行换气。
具体地，顶座121上设有相互连通的换气槽1215和导气槽1216，导气槽1216与外界气体或雾化腔120连通；换气槽1215位于两个子储液腔101的相邻处，且分别与两个子储液腔101连通，以使换气气泡可以较为随机的进入两个子储液腔101中，保证两侧均能够进行换气，而不是仅有单侧能够进行换气，使得两侧均能够下液，保证供液充足。
具体地，换气槽1215和导气槽1216均设置于顶座121的侧面，换气槽1215设于导气槽1216靠近储液腔10的一侧。换气槽1215沿雾化器1的轴向方向延伸，换气槽1215为导气槽1216靠近储液腔10一侧的凹槽。导气槽1216包括多个间隔设置且沿雾化器1的周向延伸的子导气槽1216a，多个子导气槽1216a之间相互连通或依次连通。换气槽1215通过导气槽1216的侧壁上的开口(图未标)与导气槽1216连通。
在本实施例中，密封件14设于顶座121的表面和侧面，密封件14位于顶座121的侧面的部分盖设于换气槽1215和导气槽1216的开口，即，密封件14与换气槽1215配合形成换气孔(图未标)，密封件14与导气槽1216配合形成换气通道(图未标)，换气孔和换气通道组合形成雾化器1的换气结构。由于换气槽1215与导气槽1216相互连通，密封件14与换气槽1215、导气槽1216配合形成的换气孔和换气通道相互连通；导气槽1216与外界气体或雾化腔120连通，密封件14和导气槽1216配合形成的换气通道与外界气体或雾化腔120连通。
换气槽1215设于隔片112在顶座121上的投影处，以使换气槽1215位于两个子储液腔101的相邻处；隔片112的两侧均有部分换气槽1215暴露，以使换气槽1215分别与两个子储液腔101直接连通。具体地，顶座121上设有两个对称的换气槽1215，两个换气槽1215与两个隔片112一一对应设置；即，一个隔片112在顶座121上的投影处设有一个换气槽1215。
由于隔片112与密封件14抵接，隔片112位于换气槽1215的上方，隔片112会对进入 换气槽1215的换气气泡起到阻挡作用，以对换气气泡进行缓速或卡在换气槽1215内，利用气泡随机流动的特性，卡住或缓速的气泡随机进入两个子储液腔101，实现对两个子储液腔101的随机换气。其中，换气槽1215形成的开阔空间与隔片112配合形成的腔体可以有效的对换气气泡进行缓速。
可以理解，在电子雾化装置加热雾化的开始阶段，若出现气泡只往两个子储液腔101中一侧运动的情况，在抽吸几口后，气泡会卡在换气这一侧对应的子换气槽1215a中，从而使得换气气泡向另一侧运动，实现两侧换气的目的，整体呈现处“伪随机”状态。在雾化器1倒置(发热体13位于储液腔10上方)，换气槽1215处于液封状态，不会影响上述所述的U型结构的储液功能。
在本实施例中，换气槽1215为沿雾化器1轴向延伸的凹槽，隔片112垂直于换气槽1215的宽度方向设置。隔片112在顶座121上的投影将换气槽1215分隔为两个子换气槽1215a。一个子换气槽1215a对应于一个子储液腔101，对该子储液腔101进行换气；另一个子换气槽1215a对应于另一个子储液腔101，对该子储液腔101进行换气。
可选的，换气槽1215的宽度W1大于0.2mm，以使其具有足够的宽度能够与两个子储液腔101分别连通。
可选的，换气槽1215的宽度W1大于导气槽1216的宽度W2；和/或，换气槽1215的深度大于等于导气槽1216的深度，以使与两个子储液腔101直接连通的换气槽1215形成相对于导气槽1216的开阔空间，实现对换气气泡的缓速，缓速的气泡可以较为随机的进入两个子储液腔101中，保证两侧均能够进行换气，而不是仅有单侧能够进行换气，使得两侧均能够下液，保证供液充足。在一实施方式中，换气槽1215的宽度W1为4倍-10倍导气槽1216的宽度W2，以形成相对于导气槽1216的开阔空间。
参阅图17，换气槽1215包括第一槽段1215b和第二槽段1215c，第一槽段1215b位于第二槽段1215c靠近储液腔10的一侧，第一槽段1215b的宽度大于第二槽段1215c的宽度。进一步，在换气槽1215的中间位置设有分隔柱1217，分隔柱1217设于第一槽段1215b，分隔柱1217将换气槽1215分隔为两个子换气槽1215a，一个子换气槽1215a与一个子储液腔101连通，另一个子换气槽1215a与另一个子储液腔101连通；子换气槽1215a的宽度大于导气槽1216的宽度。需要说明的是，隔片112在顶座121上的投影与分隔柱1217重合。通过设置分隔柱1217，除了能对气泡起到阻挡作用，还可以起到分割气泡的作用，随机卡泡，避免一直单侧换气。
可以理解，换气槽1215的中间位置是否设置分隔柱1217，均可以通过换气槽1215形成的开阔空间与隔片112配合形成的腔体有效的对换气气泡进行缓速，随机卡泡，避免一直单侧换气；而在换气槽1215的中间位置设置分隔柱1217，进一步对换气气泡进行缓速，且可以分割气泡，能够更好的避免单侧换气。分隔柱1217为可选结构，根据需要进行设计。
请参阅图18，图18是本申请提供的雾化器第七实施例中储液腔、出液孔及锁液腔的简易结构示意图。
雾化器1的第七实施例与雾化器1第一实施例的结构基本相同，不同之处在于：只有一个子储液腔101，相同部分不再赘述。
在子储液腔101与出液孔1211的连接处形成截面突变结构，截面突变结构使出液孔1211内的气溶胶生成基质形成液膜，将锁液腔130的气溶胶生成基质封锁在锁液腔130内。截面突变结构的具体设置方式可参见雾化器1第一实施例中的具体介绍，实现相同的技术效果，不再赘述。本实施例中，出液孔1211相对于子储液腔101和锁液腔130均形成收缩。在其他实施例中，出液孔1211可以仅相对于子储液腔101形成收缩，而与锁液腔130的截面形状和尺寸相同。
请参阅图19，图19是本申请提供的雾化器第八实施例中储液腔、出液孔及锁液腔的简易结构示意图。
雾化器1的第七实施例与雾化器1第一实施例的结构基本相同，不同之处在于：储液腔10包括两个以上的子储液腔101，多个子储液腔101与出液孔1211为一一对应关系，多个出液孔1211分别与锁液腔130流体连通，相同部分不再赘述。
在每个子储液腔101与出液孔1211的连接处均形成截面突变结构，截面突变结构使出液孔1211内的气溶胶生成基质形成液膜，将锁液腔130的气溶胶生成基质封锁在锁液腔130内。多个子储液腔101位于锁液腔130下方时，多个子储液腔101彼此之间不串流气体和/ 或气溶胶生成基质。多个子储液腔101的出液孔1211的截面突变结构在雾化器1的中轴线上的同一高度位置。截面突变结构的具体设置方式可参见雾化器1第一实施例中的具体介绍，实现相同的技术效果，不再赘述。
需要说明的是，本申请提供的上述雾化器1的实施例，可以根据需要进行任意组合，均属于本申请的保护范围。
以上仅为本申请的实施方式，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他相关的技术领域，均同理包括在本申请的专利保护范围内。
