具体实施方式
下面将参照附图更详细地描述本公开的优选实施例。虽然附图中显示了本公开的优选实施例，然而应该理解，可以以各种形式实现本公开而不应被这里阐述的实施例所限制。相反，提供这些实施例是为了使本公开更加透彻和完整，并且能够将本公开的范围完整地传达给本领域的技术人员。
在本文中使用的术语“包括”及其变形表示开放性包括，即“包括但不限于”。除非特别申明，术语“或”表示“和/或”。术语“基于”表示“至少部分地基于”。术语“一个示例实施例”和“一个实施例”表示“至少一个示例实施例”。术语“另一实施例”表示“至少一个另外的实 施例”。术语“第一”、“第二”等等可以指代不同的或相同的对象。
如上所述，常规的雾化器通常通过雾化介质仓的负压来锁住雾化介质，从而防止雾化器漏液。常规的雾化器在灌注完雾化介质后，可以通过多孔的雾化芯吸收雾化介质而在雾化介质仓中产生一定的负压来锁住雾化介质，或者可以通过在雾化芯中设置储液槽来存储雾化器中泄露的雾化介质，从而达到提升雾化介质仓的负压以锁住雾化介质的目的。在雾化芯中设置的用来存储泄露的雾化介质的储液槽在本文中可以称为直液式的储液槽。
然而，当雾化器在环境温度差异巨大的不同地点之间进行运输时，雾化器所经历的环境温度会急剧变化，这种温度变化会使雾化介质仓内与气流通道内的压力产生较大的正压力差。这种正压力差会将雾化介质挤出雾化介质仓，除非雾化芯中设置的直液式的储液槽足够多，否则仍然会有雾化介质泄露。此外，在大容量和长时间抽吸情况下，在抽吸周期的后期，雾化介质仓中无雾化介质的气体空间增加，这会使得每口抽吸所消耗的雾化介质量将不足以引起该气体空间的变化。因此，在抽吸后期，雾化介质仓内的气体压力将会不足以锁住雾化介质，导致在抽吸时出现漏液现象。此外，在抽吸周期的后期，例如在雾化介质仓具有2ml的雾化介质灌注容量且抽吸剩余0.6ml或更少的雾化介质余量的情况下，雾化器尤其容易受到环境温度波动的影响，导致出现漏液问题。因此，在抽吸后期或在雾化器所经历的环境温度急剧变化的情况下，采用负压方式仍然难以可靠地防止漏液。漏液问题一方面会造成高粘度的雾化介质的浪费，另一方面可能会造成抽吸通道堵塞，从而导致雾化器无法正常工作。
基于此，本公开的实施例提供了一种雾化器以及包括该雾化器的电子 雾化装置。在该雾化器中，设置了与雾化介质仓连通的换气介质仓，并且设置了与换气介质仓连通的漏液收集仓。利用这种布置，在抽吸后期或在雾化器所经历的环境温度急剧升高的情况下，雾化器的换气介质仓中的可牺牲介质优先泄露到漏液收集仓中，而雾化介质仓中的雾化介质将不会发生泄露，这一方面能够避免高粘度的雾化介质的浪费，另一方面可以防止因漏液而导致的抽吸通道堵塞问题，确保雾化器在抽吸时能够可靠运行。此外，与常规的经由雾化介质的换气方案相比，经由第一换气孔进入到第二内部空间中的气泡能够在可牺牲介质中快速上升，从而解决雾化介质换气困难的问题。
下面将结合图1至图4来详细描述本公开的原理。首先参考图1，图1示出了根据本公开的一个实施例的雾化器的剖面示意图。如图1所示，在此描述的雾化器100总体上包括第一储液仓1、第二储液仓2、雾化芯3和漏液收集仓5。第一储液仓1用于容纳具有较高粘度的雾化介质10。雾化介质10可以包括烟油或药液等。在雾化介质10为烟油的情况下，第一储液仓1也可以称为油仓。第二储液仓2用于容纳具有较低粘度的可牺牲介质20。可牺牲介质20在本文中也可以称为换气介质。可牺牲介质20的粘度小于雾化介质10的粘度，具有较低的表面张力。漏液收集仓5用于收集从第二储液仓2泄露的可牺牲介质20。在抽吸时或者在环境温度剧烈升高时，第二储液仓2中的可牺牲介质20可优先泄露到漏液收集仓5中，从而保证第一储液仓1中的雾化介质10不会发生泄露。
在一个实施例中，雾化介质10在25℃时的粘度在1000cps至10000000cps的范围内。在其他实施例中，雾化介质10在25℃时的粘度可以更高或更低，例如低于1000cps或高于10000000cps。
在一个实施例中，可牺牲介质20在25℃时的粘度在1cps至200cps的范围内。在其他实施例中，可牺牲介质20在25℃时的粘度可以更高或更低，例如低于1cps或高于200cps。在一个实施例中，可牺牲介质20包括以下至少一项：水、水溶液、乙醇溶液、丙二醇(PG)和丙三醇(VG)。可以理解，上述物质仅仅是可牺牲介质20的示例，粘度小于雾化介质10的任何其他成本较低的液体都可以用作可牺牲介质20。
应当注意，上述以及本公开其他地方可能提及的数字、数值等，都是示例性的，无意以任何方式限制本公开的范围。任何其他适当的数字、数值都是可能的。
可牺牲介质20的粘度小于雾化介质10并且成本远低于雾化介质10。通过使第二储液仓2中的可牺牲介质20优先泄露到漏液收集仓5中，能够防止第一储液仓1中的雾化介质10发生泄露，从而避免因雾化介质10的泄露而造成的成本浪费，并且能够解决因漏液而导致的抽吸通道堵塞的问题，保证雾化器100的可靠运行。
在一个实施例中，如图1所示，第一储液仓1具有第一内部空间11以及形成在第一储液仓1内部的雾化腔12。第一内部空间11具有预定灌注容量，用于容纳雾化介质10。作为示例，预定灌注容量可以是2ml。可以理解，预定灌注容量也可以高于或低于2ml。雾化芯3设置于雾化腔12内，用于加热雾化介质10。雾化芯3可以是陶瓷雾化芯或其他类型的雾化芯。在抽吸时，第一内部空间11中的少量雾化介质10可以克服流动阻力而流动到雾化芯3中，雾化芯3能够对雾化介质10进行加热，从而产生供抽吸的气溶胶。
在一个实施例中，如图1所示，第一储液仓1包括彼此相对的第一端 111和第二端112。第一端111邻近雾化器100的抽吸气流路径的进气端，而第二端112邻近雾化器100的抽吸端。在雾化器100沿着图1所示的竖直方向布置时，第一端111也可以称为第一储液仓1的底端，而第二端112也可以称为第一储液仓1的顶端。在一些情况下，在雾化器100沿着与图1所示的方向相反的方向布置时，即相对于图1所示的竖直方向倒置时，第一端111可以是第一储液仓1的顶端，而第二端112可以是第一储液仓1的底端。可以理解，在雾化器100沿着水平方向或倾斜方向布置时，第一端111和第二端112也将相应地朝向其他方向。
在一个实施例中，如图1所示，雾化腔12邻近第一储液仓1的第一端111设置。以此布置，当每次抽吸时，第一储液仓1中的少量雾化介质10可以克服流动阻力沿着雾化芯3的周界均匀地流向雾化芯3，从而进行雾化。可以理解，在其他实施例中，雾化腔12也可以相对于第一储液仓1居中设置，或是设置在第一储液仓1内部的其他位置。
在一个实施例中，如图1所示，第一储液仓1还开设有与雾化腔12连通的气流通道13。气流通道13从雾化腔12延伸至第一储液仓1的第二端112。在抽吸时，气体可以经由进气口6进入到雾化腔12中，进而与由雾化芯3所产生的气溶胶一起流经气流通道13。气流通道13、雾化腔12以及进气口6一起形成雾化器100的抽吸气流路径。气流通道13可以沿竖直方向或其他方向延伸，可以具有均匀或渐变的径向尺寸，也可以包括单个通道或与雾化腔12连通的多个子通道。
在一个实施例中，如图1所示，第二储液仓2设置在第一储液仓1的位于第一端111与第二端112之间的侧壁上。换而言之，第二储液仓2沿着竖直方向与第一储液仓1基本上并排布置，且共用同一个侧壁。第二储 液仓2包括邻近第一储液仓1的第一端111的第三端23和邻近第一储液仓1的第二端112的第四端24。在雾化器100沿着图1所示的竖直方向布置时，第三端23也可以称为第二储液仓2的底端，而第四端24也可以称为第二储液仓2的顶端。第二储液仓2的第三端23可以与第一储液仓1的第一端111基本齐平。第二储液仓2的第四端24可以与第一储液仓1的第二端112基本齐平。可以理解，沿着图1所示的竖直方向，第二储液仓2的第三端23也可以高于或低于第一储液仓1的第一端111，而第二储液仓2的第四端24也可以高于或低于第一储液仓1的第二端112。
在一个实施例中，如图1所示，第二储液仓2具有用于容纳可牺牲介质20的第二内部空间21。第二内部空间21通过连接通道4与第一内部空间11连通。连接通道4内设有允许气体通过并且阻止雾化介质10和可牺牲介质20通过的隔膜42。在一些实施例中，连接通道4包括形成在第一储液仓1的侧壁上的通孔41。隔膜42设置在通孔41中。隔膜42可以允许第一内部空间11与第二内部空间21之间的气体交换，而不允许雾化介质10流动到第二内部空间21中，也不允许可牺牲介质20流动到第一内部空间11中。利用隔膜42，可以保持第一内部空间11与第二内部空间21内的气压基本上相等。
在一些实施例中，隔膜42包括以下至少一项：多孔聚四氟乙烯(PTFE)膜、多孔碳膜、多孔聚偏二氟乙烯(PVDF)膜、多孔膨胀聚四氟乙烯(EPTFE)膜和碳纤维膜。可以理解，上述膜材料仅仅是隔膜42的示例材料，允许气体通过并且阻止雾化介质10和可牺牲介质20通过的任何其他膜材料都可以用来形成隔膜42。
可以理解，第二储液仓2可以以任何适当的方式设置在第一储液仓1 的侧壁上。例如，在一些实施例中，如图1所示，第二储液仓2可以仅设置在第一储液仓1的部分侧壁上。在一些实施例中，第二储液仓2可以环绕第一储液仓1的整个侧壁设置。在一些实施例中，第二储液仓2也可以设置在第一储液仓1的第二端112上。
在一些实施例中，第二储液仓2也可以与第一储液仓1间隔设置。在这种情况下，为了实现第一内部空间11与第二内部空间21之间的气体连通，连接通道4可以包括连接第二储液仓2和第一储液仓1的管路。
在一个实施例中，如图1所示，第二储液仓2上开设有允许气体进入第二内部空间21的第一换气孔22。第一换气孔22对可牺牲介质20的流动阻力小于雾化介质10从第一内部空间11流向雾化芯3所经受的流动阻力。因此，第一换气孔22可以在抽吸时作为漏液路径并且在停止抽吸时作为换气路径。利用这种布置，在抽吸时或者在环境温度剧烈升高时，第二储液仓2中的可牺牲介质20可以经由第一换气孔22优先泄露到漏液收集仓5中，而第一储液仓1中的雾化介质10不会发生泄露。在停止抽吸时，漏液收集仓5中的气体可以经由第一换气孔22进入到第二内部空间21中，从而完成换气。
在一些实施例中，如图1所示，连接通道4邻近第一储液仓1的第二端112以及第二储液仓2的第四端24设置，并且第一换气孔22设置在第二储液仓2的第三端23。利用这种布置，在进行抽吸时，第一内部空间11和第二内部空间21的顶部部分可以分别形成气体空间，并经由连接通道4连通，从而确保第一内部空间11与第二内部空间21内的气压基本上相等。
在一个实施例中，如图1所示，漏液收集仓5具有第三内部空间51， 第三内部空间51经由第一换气孔22与第二内部空间21连通并且经由第二换气孔52与雾化腔12连通。漏液收集仓5用于收集从第二内部空间21经由第一换气孔22泄露的可牺牲介质20。由于第一换气孔22对可牺牲介质20的流动阻力小于雾化介质10从第一内部空间11流向雾化芯3所经受的流动阻力，因此在抽吸时或者在环境剧烈升高时，第二储液仓2中的可牺牲介质20可以经由第一换气孔22优先泄露到漏液收集仓5中，而第一储液仓1中的雾化介质10不会发生泄露。在停止抽吸时，漏液收集仓5中的气体可以经由第一换气孔22进入到第二内部空间21中，从而完成换气。由于可牺牲介质20的粘度较小，因此气体在经由第一换气孔22进入到第二内部空间21后，气泡能够以较快的速度在可牺牲介质20中上升，到达顶部的气体空间，从而能够可靠顺畅地完成换气，避免雾化芯3发生焦糊。
在一个实施例中，如图1所示，漏液收集仓5邻近第一储液容器1的第一端111以及第二储液容器2的第三端23设置，且漏液收集仓5的底部开设有与雾化腔12连通的进气口6。在抽吸时，气体可以经由进气口6进入到雾化腔12中，进而与由雾化芯3所产生的气溶胶一起流经气流通道13。以此布置，气流通道13、雾化腔12以及进气口6一起形成雾化器100的抽吸气流路径。第二换气孔52设置在漏液收集单元5的邻近雾化腔12的侧壁上，以使第三内部空间51与雾化腔12连通。
在一个实施例中，漏液收集仓5中设置有用于吸附泄露的可牺牲介质20的吸液件53。当第二储液仓2中的可牺牲介质20经由第一换气孔22泄露到漏液收集仓5内时，吸液件53可以可靠地吸附泄露的可牺牲介质20，进一步提升雾化器100的防漏液性能。吸液件53可以包括吸液棉或 其他类型的吸液材料。
接下来，将结合图2和图3来描述图1所示的雾化器100在抽吸时和停止抽吸时的气体流动路径。为了便于描述，在此将第一内部空间11和第二内部空间21顶部的气体空间的气压定义为P1，将雾化腔12中的气压定义为P2。
图2示出了图1所示的雾化器在抽吸时的气体流动路径。如图2所示，在抽吸时，外部气体可以沿箭头701所示的方向经由进气口6进入到雾化腔12中，并且第三内部空间51中的部分气体沿箭头703所示的方向进入到雾化腔12中，进而与由雾化芯3所产生的气溶胶一起沿箭头702所示的方向流经气流通道13。在这个过程中，气压P1将会大于气压P2，使得基本相同的正压力差P1-P2同时作用在雾化介质10和可牺牲介质20上。由于第一换气孔22对可牺牲介质20的流动阻力小于雾化介质10从第一内部空间11流向雾化芯3所经受的流动阻力，因此第二储液仓2中的可牺牲介质20可以经由第一换气孔22优先泄露到漏液收集仓5中，而第一储液仓1中的雾化介质10只有少量流动到雾化芯3用于进行雾化，而其余雾化介质10不会发生泄露。可牺牲介质20泄露到漏液收集仓5中会使得气压P1降低。
在雾化器100的环境温度剧烈升高时，第二储液仓2中的可牺牲介质20能够以类似的方式优先泄露到漏液收集仓5中。具体而言，在温度升高时，气压P1会增大至大于气压P2，使得基本相同的正压力差P1-P2同时作用在雾化介质10和可牺牲介质20上。由于第一换气孔22对可牺牲介质20的流动阻力小于雾化介质10从第一内部空间11流向雾化芯3所经受的流动阻力，因此第二储液仓2中的可牺牲介质20可以经由第一换气 孔22优先泄露到漏液收集仓5中，而第一储液仓1中的雾化介质10只有少量流动到雾化芯3用于进行雾化，而其余雾化介质10不会发生泄露。
图3示出了图1所示的雾化器在停止抽吸时的气体流动路径。如图3所示，在停止抽吸时，气压P2变为大于气压P1，使得漏液收集仓5中的气体可以沿箭头704所示的方向经由第一换气孔22进入到第二内部空间21中。由于可牺牲介质20的粘度较小，因此气体在经由第一换气孔22进入到第二内部空间21后，能够以较快的速度在可牺牲介质20中上升，到达顶部的气体空间，从而能够稳定可靠地完成换气。
图4示出了根据本公开的另一实施例的雾化器的结构示意图。图4所示的第二实施例的雾化器100的结构与图1至图3所示的第一实施例的雾化器100的结构较为类似，区别仅在于第二换气孔52的设置位置不同。如图4所示，第二换气孔52设置在漏液收集仓5的邻近进气口6的侧壁上。以此方式，也实现了使第三内部空间51与雾化腔12连通。利用这种布置，同样能够保证在抽吸时或在环境温度剧烈升高时，第二储液仓2中的可牺牲介质20经由第一换气孔22优先泄露到漏液收集仓5中，而第一储液仓1中的雾化介质10只有少量流动到雾化芯3用于进行雾化，其余雾化介质10不会发生泄露。
本公开的实施例还提供了一种电子雾化装置，包括上述任一实施例的雾化器100和用于对雾化器100进行供电的电源组件。雾化器100在供电时，其中的雾化芯3可以对液态的雾化介质10进行加热雾化，以产生供抽吸的气溶胶。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只 要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对申请专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
