本申请提供一种电子雾化装置300，参阅图1至图2，图1是本申请提供的电子雾化装置一实施例的结构示意图，图2是图1所示电子雾化装置沿AA视向的剖视结构示意图。
该电子雾化装置100可以为一次性电子雾化装置，即其不可重复注液，也不可以更换存储有气溶胶基质的结构；电子雾化装置100也可以包括可拆卸连接的雾化器和主机，主机给雾化器供电，其中雾化器可更换或重复注液，雾化器用于雾化其内存储的气溶胶基质并生成供使用的气溶胶，该气溶胶基质可以是药液或营养液等。
例如，雾化器包括外壳、顶盖组件10、雾化芯和电极，其中顶盖组件10连接外壳并界定出储液腔，雾化芯至少部分地容置于顶盖组件10，且顶盖组件10内形成有雾化腔，电极连接顶盖组件10且电连接雾化芯，用于给雾化芯供电，雾化芯自储液腔吸液并在雾化腔生成气溶胶。
其中，顶盖组件10包括雾化座101，雾化座101可以包括可拆卸设置的顶盖12和底座(图未示)，雾化芯可以至少部分地容置于顶盖内，顶盖和底座之间形成有雾化腔，雾化芯的雾化面位于雾化腔；或者，雾化座101为一体式结构件，其具有如上述的顶盖12和底座所连接形成的结构，不再赘述。
本实施例中，该电子雾化装置100可以为一次性电子雾化装置，其包括顶盖组件10、外壳20、雾化芯、支架和电芯，其中顶盖组件10连接于外壳20内，并与外壳20界定出储液腔22，雾化芯至少部分地容置于顶盖组件10，支架连接顶盖组件10和/或外壳20，且支架和顶盖组件10之间形成有雾化腔，电芯连接支架背离雾化腔的一端且电连接雾化芯，其中顶盖组件10、雾化芯、支架和 电芯均容置于外壳20内。可以理解的，本实施例中的支架除具有与上述底座相同的，用于与顶盖形成雾化腔的功能外，该支架还可以作为电芯的安装结构。
其中，顶盖组件10、外壳20和雾化芯等组合而成的构件也可被命名为雾化器，本申请对此不作限定。
外壳20包括壳体24和出气管26，出气管26连接壳体24，用于将气溶胶从雾化腔输送至外界；顶盖组件10连接壳体24并与壳体24界定出储液腔22，出气管26连接顶盖组件10，以连通雾化腔。
结合参阅图2至图5，其中图3是图2所示电子雾化装置中顶盖组件一实施例的结构示意图，图4是图3所示顶盖组件中顶盖的结构示意图，图5是图2所示电子雾化装置中B区域一实施例的放大结构示意图。
顶盖组件10包括雾化座101，其中雾化座101包括顶盖12，顶盖12连接壳体24，例如顶盖12嵌设于壳体24内，或顶盖12采用螺接方式或通过螺钉、销钉等紧固件连接壳体24；顶盖12设有进液孔120和气溶胶出口122，进液孔120连通储液腔22，储液腔22内的气溶胶基质通过进液孔下液至雾化芯，出气管26连接气溶胶出口122，雾化腔内的气溶胶通过气溶胶出口122流向出气管26。
进一步地，顶盖12还设有通气孔124，通气孔124连通雾化腔，以通过雾化腔向储液腔22换气。
可选地，通气孔124还可以通过壳体24上的过孔直接连通外部大气。
顶盖12背离储液腔22的一端设有容置雾化芯的容置腔126，以及位于容置腔126两侧的过流腔128，过流腔128连通容置腔126和气溶胶出口122，通气孔124设置于顶盖12朝向储液腔22的端壁且连通过流腔128。
本实施例中，支架与顶盖12之间形成有雾化腔，雾化芯的雾化面位于雾化腔，且过流腔128连通雾化腔，进而通气孔124通过雾化腔连通外界大气。
雾化芯雾化生成的气溶胶通过顶盖12内的过流腔128流向气溶胶出口122，并在流动过程中无需接触壳体24，减少了热量耗散，使得气溶胶进入出气管26 的温度更高，从而有利于减少冷凝液的产生，气溶胶的量相对更多且温度更高，口感更佳。
通气孔124为直通孔，以便于生产，且其直接连通过流腔128，有利于使得其形成的孔深相对更小，即相对简化了制作工艺，有利于提升制作效率。
顶盖12上还设有通槽127，通槽127对应连通过流腔128及顶盖12的外周面，其中顶盖12的外周面还设有多个冷凝槽，用于收集冷凝液。
相对而言，气溶胶在顶盖组件10内或多或少会形成有一些冷凝液，这些冷凝液若不被收集起来，将聚集于支架，并增大向电芯漏液的风险。本实施例中，通槽127相对位于过流腔128的外侧，并与密封结构或壳体24形成有气流死角，以利于气溶胶在该气流死角处冷凝，并经通槽127导向顶盖12外周的冷凝槽，以被冷凝槽所收集，从而可减小支架上聚液的量，降低向电芯漏液的风险。
雾化座101还包括换气芯14，换气芯14设有换气孔道140，换气芯14连接顶盖12，且换气孔道140具有用于连通外部大气的第一端口，以及用于连通储液腔22的第二端口；其中，换气芯14与顶盖12可拆卸连接，或换气芯14与顶盖12呈一体结构。
顶盖组件10还包括封隔件16，封隔件16弹性套设于换气芯14位于储液腔22内的部分上，且封盖换气孔道140的第二端口；其中，换气孔道140一侧与储液腔22一侧之间的压差达到预设值时，封隔件16解封换气孔道140的第二端口，以使得第二端口与储液腔22连通，向储液腔22补气。
具体地，封隔件16的至少部分为弹性件，其弹性套设于换气芯14上，在储液腔22内的气压不至于过小时，其在自身弹性力的作用下紧紧地封盖换气孔道140的第二端口，以隔绝换气孔道140的第二端口和储液腔22；而在储液腔22内的气压下降的过低而致使封隔件16受压差作用而发生弹性形变，以解封换气孔道140的第二端口，使得其可连通储液腔22，并在压差作用下外界气体可通过通气孔124、换气孔道140和封隔件16与换气芯14之间形成的间隙进入储液腔22，以向储液腔22补气。
换气芯14呈管状，其可以是一端敞开且另一端封闭的管结构，或者为两端均呈敞开的管结构；封隔件16可以管套结构或管帽结构，且弹性套设于换气芯14上。
本实施例中，换气芯14的轴线垂直于顶盖12朝向储液腔22的端面，以便于安装封隔件16于换气芯14上。在其他实施方式中，换气芯14的轴线与顶盖12朝向储液腔22的端面之间还可以呈倾斜状态，本申请对此不作限定。
具体地，换气芯14和封盖件16配合用以向储液腔22内换气，实现单向进气反向锁液的功能。
储液腔22内因气溶胶基质的消耗，其内的存液量是逐渐减小的，进而导致其内气压也降低，换气芯14和封盖件16处所受到来自储液腔22的压力也是减小的，因而随着气溶胶基质的消耗，储液腔22与外部大气压形成负压差，在该负压差达到一定值时，将致使储液腔22下液不畅。
本申请中，封隔件16用于受来自换气孔道140一侧与来自储液腔22一侧之间的压差达到预设值而解封换气芯14的第二端口，换言之，封隔件16受到来自换气孔道140一侧与储液腔22一侧之间的压差达到预设值时，会解封换气芯14的第二端口，使得换气芯14的第二端口连通储液腔22，以向储液腔22内补气；而在此之前，封隔件16保持封闭换气芯14的第二端口，以阻止换气芯14的第二端口与储液腔22之间的连通。
具体地，来自换气孔道140一侧与储液腔22一侧之间的压差达到预设值时，该压差将使得封隔件16发生弹性变形，以形成连通储液腔22和换气芯14的第二端口的间隙，以对储液腔22进行补气，使得储液腔22内达到压力平衡，利于下液，并在该压差小于预设值时，封隔件16保持封闭换气芯14的第二端口，避免储液腔22内的存储液通过换气芯14泄露。
封隔件16可采用硅胶或塑胶等制成，其在两侧压持达到预设值时可发生弹性形变，以使得换气孔道140的第二端口连通储液腔22，其中该压差预设值可以是100±20Pa、200±20Pa、300±20Pa、400±20Pa或500±20Pa等，即该压 差预设值可以是一个范围。
市场上的电子雾化装置100常采用迷宫换气的方式向储液腔22内补气，即在顶盖12的外周设有迷宫换气槽，其也够实现对储液腔22补气，但在向储液腔22内注液时，其对注液量有限制，通常注液量超过5ml时，常导致因温冲、负压或高温实验等应用环境下的影响从换气槽漏液，也限制该技术的应用场景。
基于此，本申请提供了一种新的技术方案，以解除对注液量的限制，并在具有换气功能的同时还具有降低漏液风险的作用，使得换气压力调节简单、稳定且一致性好，换气顺畅。
本申请通过限定雾化座101包括换气芯14，换气芯14至少部分位于储液腔22内，且换气芯14还设有换气孔道140，换气孔道140的第一端口用于连通外部大气，且通过设置封隔件16弹性套设于换气芯14上且封盖换气孔道140的第二端口，以隔绝换气孔道140和储液腔22，并利用封隔件16来自换气孔道140和储液腔22两侧的压差以使得其能够自动实现换气压力调节，且封隔件16弹性套设于换气芯14上的方式，使得封盖件可完全地将换气通道140的第二端口包裹住，以利用其自身的弹性使得在常压下可紧密地封盖换气孔道140的第二端口，以隔绝换气孔道140的第二端口和储液腔22，且可免受被其他部件拉扯，避免在注液时等无需换气的状况下与储液腔22相通，从而使得封隔件16对换气芯14的第二端口的封盖更稳定。而且，即使碰上温冲、负压或高温实验等使得储液腔22内的压强大于大气压的应用环境，封隔件16在压差作用下能够更加紧密地套设在换气芯14上，以增加对第二端口的密封强度，进而可降低有效地降低漏液风险，使得具有该换气芯14的顶盖组件10能够用于储液腔22内注射有较大剂量的气溶胶生成基质的电子雾化装置100。
本实施例中，如图3和图5所示，换气芯14与顶盖12可拆卸连接，从而换气芯14可独立制造，相对可降低制作难度，换气芯14可与顶盖12采用过盈配合或螺接等方式连接。
顶盖组件10还包括密封件18，密封件18套设于顶盖12上，且设置于顶盖 12与壳体24、出气管26之间，以使得顶盖12与外壳20之间呈密封设置，防止漏液。
本实施例中，封隔件16与密封件18彼此相独立，即封隔件16也是一个独立的零部件，从而也便于封隔件16的制造，可降低制造难度，且也便于封隔件16与换气芯14的套设装配。
参阅图6，图6是图2所示电子雾化装置中B区域另一实施例的放大结构示意图。在另一实施例中，封隔件16与密封件18还可以呈一体结构。
换气芯14为金属管或塑胶管，换气芯14可采用金属管标件，例如铜、铝或不锈钢钢等，或者采用PCTG管(非晶型共聚酯透明塑料)等，即可使得换气芯14的结构简单易通用，且也容易标准化，其制造工艺也简单且便捷，成本低。
本实施例中，换气芯14采用金属管，且其与通气孔124过盈配合。
参阅图5和图6，换气芯14呈管状，第二端口开设于换气芯14的侧壁；换气孔道140包括换气管道142和设置于换气芯14的侧壁的换气孔144，换气孔144连通换气管道142，换气管道142连通通气孔124，封隔件16弹性套设于换气芯14的管壁，且封盖换气孔144，在封隔件16解封换气孔144时，换气孔144连通储液腔22。其中，换气管道142连通通气孔124的端口为换气孔道140的第一端口，换气孔144远离换气管道142的端口为换气孔道140的第二端口。
换气芯14的侧壁设有至少一个换气孔144，例如换气孔144的数量可以是两个、三个或四个等，其均连通换气管道142，以增加换气的快捷性。
换气芯14包括管体141和盖体143，盖体143与管体141伸入储液腔22内的一端连接，管体141的另一端连接顶盖12，换气孔144设置于管体141的管壁上，管体141形成有换气管道142，封隔件16弹性套设于管体141上，以利用其自身弹性及套设连接方式提升与换气芯14的连接稳定性，使得不管储液腔22内注液量的大小，均能够使得其在各种可靠性实验中均能够有效控制换气孔道140的漏液风险。
封隔件16可以是弹性套管，其弹性套设于管体141，其受两侧压差达到预设值时，该弹性套管发生弹性形变可从弹性套管的两端中的任一端连通储液腔22。
本实施例中，封隔件16包括管套162，管套162弹性套设于管体141上且封盖换气孔144；其中管套162受压差达到预设值而与管体141之间形成连通换气孔道140的第二端口和储液腔22的间隙，即管套162受压差达到预设值而发生弹性形变，以连通换气孔144和储液腔22。
封隔件16还包括连接管套162一端的环筋164，环筋164连接于管套162远离盖体143的一端，并沿管套162的径向向外延伸。其中，环筋164相对设置于管套162朝向顶盖12的一端，以限定该端相对另一端不易发生形变，使得管套162的另一端受压差作用发生弹性形变而连通储液腔22和换气孔144，即封隔件16发生弹性变形的一端是确定的，提升了换气压力调节的稳定性和一致性。
进一步地，如图5所示，盖体143相对管体141形成外伸的凸缘145，环筋164连接于管套162背离凸缘145的一端，管套162的另一端与凸缘145之间形成有缝隙，以便于换气，且该凸缘145可对管套162的一端进行遮挡，以增强对管套162的端部防护，避免因其他因素而变形导致储液腔22和换气孔道140在非换气时连通而漏液。
在另一实施例中，如图6所示，封隔件16与密封件18还可以呈一体结构，管套162设有环筋164的一端还连接密封件18。
在其他实施方式中，换气芯14为两端敞开的金属管，其两端口为上述的第一端口和第二端口，封隔件16为弹性帽，该弹性帽套设于换气芯14上，该弹性帽可参阅下述实施例中封隔件16的具体结构，不再赘述。
参阅图7至图9，图7是图2所示电子雾化装置中顶盖组件另一实施例的结构示意图，图8是图7所示顶盖组件沿CC视向的剖视结构示意图，图9是图7所示顶盖组件沿DD视向的剖视结构示意图。
可选地，换气芯14与顶盖12呈一体结构，而封隔件16与密封件18彼此相独立，或封隔件16与密封件18呈一体结构。
换气芯14呈管状，换气孔道140贯穿换气芯14；封隔件16包括管套162和连接管套162的顶壁166，管套162弹性套设于换气芯14的周壁上，顶壁166朝向第二端口，且顶壁166与换气芯14设有第二端口的表面之间具有间隙，即顶壁166封盖换气孔道140；其中，在压差达到预设值时，管套162与换气芯14的周壁之间形成连通其第二端口和储液腔22的间隙，即管套162受压差达到预设值而发生弹性形变，以连通换气孔144的第二端口和储液腔22。
例如，封隔件16与密封件18彼此相独立，则封隔件16发生弹性形变时不会受到密封件18的限制，可直接地向储液腔22内换气。
例如，如图7和图9所示，封隔件16与密封件18呈一体结构时，则密封件18上还设有过孔180，封隔件16发生弹性形变而与换气芯14的周壁之间形成的间隙通过该过孔180连通封隔件16背离换气芯14一侧的空间，即连通储液腔22。
结合参阅图9至图11，图10是如图7所示顶盖组件中雾化座的结构示意图，图11是如图7所示顶盖组件中封隔件与密封件的结构示意图。
如图9至图11所示，换气芯14的周壁上设有第一导气槽146，第一导气槽146的一端连通换气孔道140的第二端口；管套162上设有第二导气槽167，第二导气槽167的一端连通封隔件16背离换气芯14一侧空间，即第二导气槽167的一端用于连通储液腔22；其中，第一导气槽146和第二导气槽167彼此相向延伸，以缩短第一导气槽146和第二导气槽167之间的间距，使得第一导气槽146和第二导气槽167更容易导通，以增加换气的便捷性，使得封隔件16发生较小地弹性变形即可实现换气。
如图9和图11所示，封隔件16与密封件18呈一体结构时，第二导气槽167的一端连通过孔180，以通过该过孔180连通储液腔22，且第二导气槽167的一部分还设置于密封件18朝向顶盖12的表面。
本申请通过限定雾化座包括换气芯，换气芯至少部分位于储液腔内，换气芯还设有换气孔道，换气孔道的第一端口用于连通外部大气，且通过设置封隔件弹性套设于换气芯上且封盖换气孔道的第二端口，并利用封隔件来自换气孔道和储液腔两侧的压差以使得其能够自动实现换气压力调节，封隔件弹性套设于换气芯上的方式，使得封隔件可完全地将换气通道的第二端口包裹住，以利用其自身的弹性使得在常压下可紧密地封盖换气孔道的第二端口，以隔绝换气孔道的第二端口和储液腔，避免在注液时等无需换气的状况下与储液腔相通，从而使得封隔件对换气芯的第二端口的封盖更稳定。而且，即使碰上温冲、负压或高温实验等使得储液腔内的压强大于大气压的应用环境，封隔件在压差作用下能够更加紧密地套设在换气芯上，以增加对第二端口的密封强度，进而有效地降低漏液风险，使得具有该换气芯的顶盖组件能够用于储液腔内注射有较大剂量的气溶胶生成基质的电子雾化装置。
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。
