Description

换气模组、雾化器及电子雾化装置 技术领域
本申请涉及电子雾化装置技术领域，尤其涉及一种换气模组、雾化器及电子雾化装置。
背景技术
电子雾化装置一般包括储液腔、多孔发热体、密封件。密封件用于防止储液腔的气溶胶生成基质流到发热体以外的地方。在加热雾化的时候，储液腔内的气溶胶生成基质减少，储液腔内部的气体空间增大，气压减少，液体流向发热体的阻力增大，容易导致供液不足，产生干烧现象。
为了解决上述问题，现有的电子雾化装置通道增设连通外部气体和储液腔的换气结构，在压力差的驱动下，外部气体通过换气结构给储液腔补充气体，平衡气压。但目前的换气结构难以做到满足快速换气的同时，还防止储液腔的气溶胶生成基质通过换气通道漏出。

下面结合附图和实施例对本申请进行详细的说明。
请参阅图1，图1是本申请提供的电子雾化装置的一实施例的结构示意图。在本实施例中，提供一种电子雾化装置100。该电子雾化装置100可用于气溶胶生成基质的雾化。电子雾化装置100包括相互电连接的雾化器1和主机2。
其中，雾化器1用于存储气溶胶生成基质并雾化气溶胶生成基质以形成可供用户吸食的气溶胶。该雾化器1具体可用于不同的领域，比如，医疗、美容、休闲吸食等；在一具体实施例中，该雾化器1可 用于电子气溶胶化装置，用于雾化气溶胶生成基质并产生气溶胶，以供抽吸者抽吸，以下实施例均以此休闲吸食为例；当然，在其他实施例中，该雾化器1也可应用于喷发胶设备，以雾化用于头发定型的喷发胶；或者应用于治疗上下呼吸系统疾病的设备，以雾化医用药品。
雾化器1的具体结构与功能可参见以下实施例所涉及的雾化器1的具体结构与功能，在此不再赘述。
主机2包括电池(图未示)和控制器(图未示)。电池用于为雾化器1的工作提供电能，以使得雾化器1能够雾化气溶胶生成基质形成气溶胶；控制器用于控制雾化器1工作。主机2还包括电池支架、气流传感器等其他元件。
雾化器1与主机2可以是一体设置，也可以是可拆卸连接，可以根据具体需要进行设计。
请参阅图2，图2是本申请提供的雾化器第一实施例的结构示意图。
雾化器1包括壳体10、雾化座11和发热体12。壳体10具有储液腔13、出气通道14，储液腔13用于储存液态的气溶胶生成基质，储液腔13环绕出气通道14设置。壳体10的端部还具有抽吸口15，抽吸口15与出气通道14连通；具体地，可以是出气通道14的一端口形成抽吸口15。壳体10在储液腔13背离抽吸口15的一侧具有与储液腔13连通的容置腔16，雾化座11设置于容置腔16中。也就是说，雾化座11设置于壳体10中，并与壳体10配合形成储液腔13，雾化座11的顶面为储液腔13的底壁。
雾化座11具有收容腔111。发热体12设置于收容腔111中，同雾化座11一起设置于容置腔16中。雾化座11靠近储液腔13的一端设置有流体通道(未图示)，流体通道的一端与储液腔13连通，另一端与收容腔111连通，即，流体通道使储液腔13与收容腔111连通，以使储液腔13中的气溶胶生成基质通道流体通道进入发热体12。也就是说，发热体12与储液腔13流体相通，发热体12用于吸收并加热雾化气溶胶生成基质。
在本实施例中，发热体12远离储液腔13的表面为雾化面，发热 体12的雾化面与收容腔111的内壁面之间形成雾化腔112，雾化腔112与出气通道14连通。雾化座11上设置有进气通道113，以使外界与雾化腔112连通；具体地，进气通道113设置于雾化座11远离储液腔13的一端。外界气体通过进气通道113进入雾化腔112，携带发热体12雾化好的气溶胶进入出气通道14，最终到达抽吸口15，被用户吸食。
雾化器1还包括密封顶盖17。密封顶盖17设置于雾化座靠近储液腔13的表面，用于实现对储液腔13与雾化座11、出气通道14之间的密封，防止漏液。可选的，密封顶盖17的材料为硅胶或氟橡胶。
雾化器1还包括导通件(未图示)，导通件固定于雾化座11远离储液腔13的端部。导通件的一端于发热体12电连接，另一端用于与主机2电连接，以使发热体12能够工作。
随着加热雾化的进行，储液腔13内的气溶胶生成基质被消耗，储液腔13内部的气体空间增大，气压减少，气溶胶生成基质流向发热体12的阻力增大，容易导致供液不足，产生干烧现象。为了避免出现上述现象，现有的电子雾化装置有的使用装配间隙对储液腔进行换气，但采用该种方式进行换气的换气压力不稳定，极大程度易导致干烧或漏液。现有的电子雾化装置还有通过直液式换气结构对储液腔进行换气，可以通过换气通道的设计来调节换气压力，但通过对该种换气方式的储液腔负压曲线进行研究发现，使用直液式换气结构进行换气会导致储液腔中的负压波动较大，一般为-900Pa～-300Pa，大幅度的负压波动不利于抽吸时稳定供液；一般在抽吸结束之后才会进行换气，如果使用微孔阵列结构，或者薄片多孔结构组成发热体时，在抽吸停止的一刹那，储液腔内负压达到最大，雾化腔负压恢复为大气压，在极大的压差条件下，气泡极有可能通过发热体进入储液腔，卡在发热体靠近储液腔的表面，影响下液，从而导致干烧。因此，需要开发一种换气结构，可以实现快速换气，避免供液不足造成的干烧；同时，换气结构还需能够防止储液腔中的气溶胶生成基质通过该换气结构漏出，避免换气造成的漏液现象。
为了解决上述问题，本申请提供了一种换气模组18，换气模组 18用于对储液腔13进行换气。具体地，储液腔13的腔壁上设置有换气口131，换气模组18设置于换气口131，以对储液腔13进行换气。
请参阅图3，图3是图2提供的雾化器中换气模组的结构示意图。
换气模组18包括外壳181、单向阀182、防水透气膜183。外壳181具有进气口1811和出气口1812，单向阀182设置于进气口1811处，防水透气膜183设置于出气口1812处。外壳181内储存有预置介质184。单向阀182控制外界气体进入外壳181内部，穿过预置介质184和防水透气膜183；即，当满足单向阀182打开的条件时，外界气体通道进气口1811进入外壳181内部，穿过预置介质184和防水透气膜183从出气口1812流出。
当单向阀182的外侧气压与内侧气压的差值达到第一预设阈值时，单向阀182打开；当单向阀182的外侧气压与内侧气压的差值达到第二预设阈值时，单向阀182关闭。单向阀182的内侧指的是单向阀182朝向外壳181内部的一侧，单向阀182的外侧指的是单向阀182朝向外界气体的一侧。单向阀182的打开方向朝向外壳181的内部。可以理解，单向阀182的外侧气压与内侧气压的差值达到第一预设阈值时，单向阀182打开，单向阀182打开的大小足够气泡进入；当单向阀182的外侧气压与内侧气压的差值达到第二预设阈值时，单向阀182关闭；当单向阀182的外侧气压与内侧气压的差值在第一预设阈值与第二预设阈值之间时，单向阀182处于半开状态。
其中，单向阀182为悬臂阀、桥阀、轮式阀、伞阀、两端固支阀、弹簧阀、以及鸭嘴阀中的一种。预置介质184为液体或气体；当预置介质184为液体时，液体可以为水、丙二醇以及丙三醇中的一种或多种的混合物；当预置介质184为气体时，气体可以为空气。防水透气膜183的材料包括聚四氟乙烯，能耐高温。防水透气膜183具有多个孔径为1μm-50μm的微孔，以使气体通过并防止液体通过。预置介质184要求无毒，其表面张力不能过低，以防止预置介质184随着外界气体一起进入储液腔13。
继续参见图2，换气模组18设置于换气口131处，换气模组18 的出气口1812与储液腔13连通，实现对储液腔13的换气。当外界气体的气压与储液腔13内的气压的差达到第一预设阈值时，单向阀182控制外界气体通过换气模组18进入储液腔13内。具体地，当外界气体的气压与储液腔13内的气压的差达到第一预设阈值时，外界气体通道进气口1811进入外壳181内部，穿过预置介质184和防水透气膜183从出气口1812流至储液腔13，完成换气过程。可以理解，换气模组18的单向阀182的阀片覆盖换气口131，以实现单向阀182控制外界气体何时进入储液腔13，并防止储液腔13内的气溶胶生成基质从换气口131漏出。
在一实施方式中，当外界气体的气压与储液腔13内的气压的差达到第一预设阈值时，单向阀182打开，外界气体控进入储液腔13；当外界气体的气压与储液腔13内的气压的差低于第一预设阈值时，单向阀182关闭；即，当储液腔13内的负压为第一预设阈值时，单向阀182打开；当储液腔13内的负压低于第一预设阈值时，单向阀182关闭。
在另一实施方式中，当储液腔13内的负压为第一预设阈值时，单向阀182打开，外界气体控进入储液腔13；当储液腔13内的负压为第二预设阈值时，单向阀182关闭。可选的，第一预设阈值为-300pa～-500pa，第二预设阈值为-100pa～-200pa。可以理解，由于单向阀182的阀片张开的大小可以控制气泡的大小，当几个小气泡与一个大气泡换气量相当时，小气泡换气会使储液腔13中的负压波动较小，因此，可以通过单向阀182的阀片张开的大小来控制气泡的大小，也就是说，可以通过单向阀182的形变量与其内外两侧压差之间的关系来设置第一预设阈值和第二预设阈值，实现小气泡换气。
在本实施例中，换气口131设置于储液腔13的底壁。具体地，在雾化座11的顶面具有凹坑114，凹坑114作为换气口131。换气模组18设置于凹坑114内，即，换气模组18位于换气口131内。换气模组18的防水透气膜183与储液腔13内的气溶胶生成基质接触。防水透气膜183将储液腔内的气溶胶生成基质与预置介质184分隔开，防水透气膜183只允许气体通过，不允许气溶胶生成基质和预置介质 184液体通过。
通过将换气口131设置于储液腔13的底壁，换气模组18设置于换气口131内，由于液位高度原因，换气模组18的单向阀182易闭合，能有效的防止漏液；且对于现有的电子雾化装置，只需更改雾化座11的顶面结构即可，加工较简单，适用性较广。而随着液位的高度的降低，压力变化导致的单向阀182张合压差变化范围不大，在100Pa左右，对换气的稳定性影响较小。
可以理解，当在换气口131处设置单向阀，通过单向阀控制换气过程时，在储液腔13中还有较多气溶胶生成基质的状态下，单向阀浸润于气溶胶生成基质，气溶胶生成基质对单向阀的阀片会有较强的粘附力，即，单向阀处于湿模态；随着雾化的进行，储液腔13中的气溶胶生成基质被消耗的越来越少，单向阀可能不与气溶胶生成基质接触，单向阀从湿模态转换成干模态。而单向阀的阀片在湿模态和干模态下的张开力度会有极大变化，不利于换气压力的稳定。
本申请提供的换气模组18通过在外壳181内储存预置介质184，使得位于外壳181进气口1811处的单向阀182的阀片一直处于湿模态，保证单向阀182的阀片的张合的一致性，以保证换气压力的稳定。
本申请通过换气模组18对储液腔13进行换气，换气模组18的防水透气膜183防止气溶胶生成基质通过，且换气模组18的单向阀182覆盖换气口131，实现在换气的同时防止气溶胶生成基质从换气口131漏出。
在本实施例中，雾化座11还具有换气通道19，换气通道19的一端与外界气体连通，换气通道19的另一端与凹坑114连通。可选的，换气通道19的另一端延伸至凹坑114的底面，从而与凹坑114连通；换气模组18的单向阀182的阀片覆盖该换气通道19的端口，确保气溶胶生成基质不会从换气口131漏液，并控制外界大气是否可以进入储液腔13。
在一实施方式中，换气通道19的一端与雾化腔112连通，换气通道19通过雾化腔112与外界气体连通。在一实施方式中，换气通道19的一端直接与外界气体连通，并不经过雾化腔112；即，换气 通道19为从凹坑114的底面延伸至雾化座11的底面的通孔，换气通道19与雾化腔112间隔设置(如图2所示)。
可以理解，在其他实施方式中，可以将换气模组18设置于储液腔13中，换气模组18的单向阀182的阀片覆盖换气口131，凹坑114作为换气口131；即，换气模组18浸润于储液腔13的气溶胶生成基质中，单向阀182设置于凹坑114的开口处并覆盖凹坑114的开口，以防止气溶胶生成基质从换气口131漏出。
请参阅图4，图4是本申请提供的雾化器第二实施例的结构示意图。
图4提供的雾化器1与图2提供的雾化器1区别在于：换气口131的设置位置不同，除此之外的结构设置基本相同，相同部分不再赘述。可以理解，换气模组18对应于换气口131设置，换气口131设置位置不同，换气模组18设置位置也不同。
图4结合图3，在本实施例中，换气口131设置于储液腔13的侧壁，换气模组18设置于储液腔13中，换气模组18的单向阀182覆盖换气口131。
具体地，换气口131为设置于储液腔13的侧壁上的通孔。由于壳体10与雾化座11配合形成的储液腔13，储液腔13的侧壁为壳体10的侧壁。换气模组18浸润于储液腔13的气溶胶生成基质中。单向阀182可以设置于换气口131靠近储液腔13内部空间的端口处，单向阀182也可以设置于换气口131的中间部分，单向阀182也可以设置于换气口131远离储液腔13内部空间的端口处。
可以理解，换气口131设置于储液腔13的侧壁的高度可以根据需要进行设计，本申请对此并不限定。对于现有的电子雾化装置，只需将换气模组18整体设置于储液腔13中即可，加工简单，适用性较广；而随着液位的高度的降低，压力变化导致的单向阀182张合压差变化范围不大，在100Pa左右，对换气的稳定性影响较小。
请参阅图5，图5是本申请提供的雾化器第三实施例的结构示意图。
图5提供的雾化器1与图2提供的雾化器1区别在于：换气口 131的设置位置不同，除此之外的结构设置基本相同，相同部分不再赘述。可以理解，换气模组18对应于换气口131设置，换气口131设置位置不同，换气模组18设置位置也不同。
图5结合图3，在本实施例中，换气口131设置于储液腔13的顶壁，换气模组18设置于储液腔13中，换气模组18的单向阀182覆盖换气口131。
具体地，换气口131为设置于储液腔13的顶壁上的通孔。由于壳体10与雾化座11配合形成的储液腔13，储液腔13的顶壁为壳体10的顶壁。壳体10的端部具有抽吸口15，换气口131与抽吸口15间隔设置。在本实施例中，雾化器1还包括吸嘴盖101，吸嘴盖101套设于壳体10的端部并覆盖换气口131，且吸嘴盖101上对应于抽吸口15设置有通孔1011，以使用户能够吸食到气溶胶。若不在壳体10的端部套设吸嘴盖101，用户在抽吸时，口腔内部的压力会影响换气口131处单向阀182的打开，可能会在储液腔13内还不需换气时打开单向阀182，因此，可以通过在壳体10的端部套设吸嘴盖101，吸嘴盖101覆盖换气口131，可以平衡压力，减小用户抽吸时的压力波动对打开单向阀182的影响。可以理解，吸嘴盖101虽然覆盖换气口131，但并没有使换气口131封闭，还是能够使换气口131与外界气体连通的。
可以理解，换气模组18浸润于储液腔13的气溶胶生成基质中。单向阀182可以设置于换气口131靠近储液腔13内部空间的端口处，单向阀182也可以设置于换气口131的中间部分，单向阀182也可以设置于换气口131远离储液腔13内部空间的端口处。对于现有的电子雾化装置，只需将换气模组18整体设置于储液腔13中即可，适应性较广，加工简单。
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。
