背景技术
电子雾化装置的雾化器内置加热元器件，通过电池供电发热，使发热体附近的液体基质挥发，形成气溶胶。当雾化器储液仓内液体基质形成气溶胶被吸出，储液仓内形成负压，需要进气补偿平衡压力。
目前，市面上的圆柱陶瓷雾化器通常采用陶瓷外包棉的结构形式，即在圆柱陶瓷发热体外表面包棉，以此来进行导液和锁液，这种方式会造成该工序很难做到自动化组装，而且人工组装带来生产的稳定性能差。导致产品一致性低，雾化效率低，TPM(Total Particulate Matter，总粒相物)不稳定，容易产生糊味或者漏液，降低口感。
而采用传统不包棉陶瓷芯结构往往在抽吸后，气溶胶在温度降低后形成冷凝液而累积在陶瓷中心孔，造成堵孔问题，用户体验较差。

以下本申请实施例描述电子雾化装置1000的示例性结构。
如图1所示，本申请提供的电子雾化装置1000包括雾化器100，以及为该雾化器供电的电源机构200。电子雾化装置1000可以用于医用或者其他用途。其中，雾化器100可以作为分体式的电子雾化装置1000的一部分，用于将储存于其内的液体基质雾化。电源机构200与雾化器100电连接，其内部可以装载可拆卸的电池，便于用户更换。
以下本申请实施例描述雾化器100的示例性结构。
如图2和图3所示，雾化器100包括沿纵向方向相背离的近端1和远端2、吸气口3、储液腔4、多孔体5、通孔6和加热元件7。
其中，吸气口3位于近端1。吸气口3为雾化器100的出气方向，用户通过吸气口3吸食液体基质被雾化所形成的气溶胶。
储液腔4用于存储液体基质。液体基质可以是含有药物或者其他活性成分的液体。
如图3所示，多孔体5与储液腔4流体连通进而至少部分接收或吸取液体基质。如图4所示，多孔体5包括靠近近端1的第一端51、以及靠近远端2的第二端52。多孔体5可以是以刚玉砂、碳化硅、堇青石等优质原料为主料、经过成型和特殊高温烧结工艺制备的一种具有开孔孔径、高开口气孔率的一种多孔性陶瓷材料，具有耐高温，高压、抗酸、碱和有机介质腐蚀，良好的生物惰性、可控的孔结构及高的开口孔隙率、使用寿命长、产品再生性能好等优点。多孔体5也可以由玻璃纤维等其他不同材料制成。
如图4所示，通孔6由多孔体5的第一端51贯穿或延伸至第二端52。通孔6包括靠近第一端51的第一区段61、以及靠近第二端52的第二区段62。其中，第二区段62在第二端52处的横截面积大于在靠近第一区段61处的横截面积。因此，液体基质被雾化后形成的气溶胶在温度降低之后形成的冷凝液利于沿着第二区段62的外周朝远端2的方向流出，避免多孔体5被冷凝液堵塞而影响进一步的雾化效果。
如图4所示，第一区段61的横截面积基本恒定。例如，在本实施例中，第一区段61可以被设置为横截面积一致的圆柱体形状。第二区段62的横截面积沿靠近第一区段61的方向逐渐减小。例如，在本实施例中，第二区段62可以被设置为喇叭口的形状，其横截面积沿靠近第一区段61的方向逐渐减小。进一步地，第一区段61的长度大于第二区段62的长度。其中，第一区段61的长度为4-8mm；和/或，第二区段62的长度为2-4mm。例如，在一些实施例中，第一区段61的长度为4mm，第二区段62的长度为2mm；或者第一区段61的长度为6mm，第二区段62的长度为3mm；或者第一区段61的长度为8mm，第二区段62的长度为4mm等。
如图5所示，在另一实施例中，第二区段62的横截面积基本恒定。例如，其形状可以配置为与前述实施例不同的喇叭口不同的圆柱体型。换言之，第一区段61为横截面积一致的圆柱体形状，而第二区段62为横截面积一致但大于第一区段61的横截面积的圆柱体形状。
在其他实施例中，第一区段61也可以称为第一子段，第二区段62 也可以称为第二子段。第一子段与第一区段61的结构和功能相同，第二子段与第二区段62的结构和功能相同。
如图4所示，加热元件7结合于多孔体5并毗邻通孔6布置，以用于加热多孔体5的至少部分液体基质生成气溶胶。加热元件7被布置成至少部分围绕第一区段61并避开第二区段62。因此，液体基质集中于通孔的第一区段61内被雾化形成气溶胶。
如图4所示，加热元件7具体可包括发热丝71、与发热丝71两端分别连接的第一引线72和第二引线73。该发热丝71呈螺旋状缠绕设置在该多孔体5的第一端51的至少部分内壁并避开第二端52，利于将多孔体5吸收的液体基质充分雾化。在其他实施例中，发热丝71也可以呈网格状等不同形式设置，以利于将不同理化性质的液体基质充分加热雾化。加热元件7在通电状态下发热，以将由多孔体5外部渗入的液体基质进行雾化，通常由金属丝(例如是镍铬合金等)制成。
其中，多孔体5和加热元件7的组合也可以称为雾化组件，用于雾化液体基质生成气溶胶。
如图3和图6所示，雾化器100还可以包括第一管状元件8，并且该多孔体5还可包括弹性元件9。该第一管状元件8至少部分沿雾化器100的纵向方向于储液腔4内延伸。多孔体5被容纳或保持于第一管状元件8内。
如图4所示，进一步地，多孔体5可以包括第一部分53和第二部分54。其中，第一部分53围绕或界定通孔6的第一区段61；第二部分54围绕或界定通孔6的第二区段62。可以通过结烧等方式将第一部分53和第二部分54一次性成型。其中，第一部分53的底端的外壁与第一管状元件8的内壁之间的间隙在0.2mm以内。如此，可避免换气气泡在第一部分53外壁和第一管状元件8内壁之间的间隙中长大，累积成大气泡影响储液腔4内部负压，进而影响液体基质向多孔体5渗入。
如图3和图6所示，弹性元件9至少部分弹性抵接于第一管状元件8和第二部分54之间。第一管状元件8至少通过弹性元件9弹性耦合于第二部分54，以使多孔体保持在第一管状元件8内。弹性元件9在第二部分54和第一管状元件8之间被沿径向挤压或压缩。进一步地，第一管状元件8用于界定或围绕传输管81。该传输管81与雾化器100的近端1和远端2相互连通，因而多孔体5内被雾化的气溶胶能够沿气流路径流动至吸气口3。
如图4和图7所示，在另一个实施例中，多孔体5的弹性元件9可实施为柔性第一密封件。该柔性第一密封件至少部分位于第二部分54 和第一管状元件8之间，以在它们之间提供密封。如此，多孔体5易于被固定于第一管状元件8之内而不发生位移。柔性第一密封件的材质可以是硅胶、橡胶等软性材料。进一步地，多孔体5还可以包括柔性第二密封件55。该柔性第二密封件55至少部分位于第一部分53和第一管状元件8之间，以在它们之间提供密封。柔性第二密封件55的材质同样可以是硅胶、橡胶等软性材料。柔性第一密封件和柔性第二密封件55的配合可避免多孔体5装入第一管状元件8内时出现拉扯、翻边、脱出等装配不良的情况。
如图2和图3所示，雾化器100还可以包括第一承接元件1010。该第一承接元件1010位于第二区段62在第二端52的端口与远端2之间，以用于承接气溶胶冷凝液。沿雾化器100的纵向方向，第一承接元件1010至少部分与通孔6相对或对准。第一承接元件1010朝向通孔6和/或多孔体5的表面上设置有第一凹腔101，以用于容纳或保持所承接的气溶胶冷凝液，避免长期漏液而腐蚀其他组件。第一承接元件1010朝向通孔6和/或多孔体5的中心区域还开设有中心孔102。中心孔102的横截面沿着远离通孔6和/或多孔体5的方向逐渐增大。例如，中心孔102的形状可以是喇叭口型、锥型等。如此，便于第一凹腔101内溢出的冷凝液沿中心孔102向下流，防止堵塞第一承接元件1010的中心孔102。
如图2和图3所示，雾化器100还可以包括吸嘴组件11、外壳12和底座组件13。其中，吸嘴组件11用于界定雾化器100的近端1，且其内部开设有出气孔111。该出气孔111与传输管81相连通，使得气溶胶朝向雾化器100的近端1方向流出。外壳12连接于吸嘴组件11远离近端1的另一端，底座组件13与外壳12远离吸嘴组件11的另一端连接。
外壳12的内壁和第一管状元件8的外壁界定储液腔4，且储液腔4的两端分别被吸嘴组件11和底座组件13封堵，以形成密闭的空间。外壳12的材质可以设置为透明的，以方便用户观测其内的液体基质的含量，待液体基质消耗完后可以补充。
第一管状元件8与多孔体5的第二部分54抵接的外周可以开设有若干个壁孔82。储液腔4内的液体基质可以通过若干个壁孔82向多孔体5渗透，以待进一步被雾化形成气溶胶。例如，在本实施例中，壁孔82的数量为两个，且分别对应于多孔体5的第二部分54的径向方向。
如图3所示，底座组件13内壁设置有绝缘环131，绝缘环131内壁套设有电极132。其中，第一引线72和第二引线73可分别与电极132和导电的底座组件13连接，以在通电后发热将液体基质雾化形成气溶 胶。电极132和底座组件13用于电连接电源机构200的正极和负极，绝缘环131用于将电极132和底座组件13绝缘，防止短路。
雾化器100还包括进气口14及位于所述进气口14与吸气口3之间的气流通道15。进气口14位于远端2。进气口14为雾化器100的进气方向。
其中，电极132被设置为中空的环状，其内壁用于界定进气孔133。进一步地，电极132的侧壁上设置有至少一个第二壁孔134，使得进气孔133进入的空气由第二壁孔134进入雾化组件。
进气口14、吸气口3和气流通道15布置成限定从进气口14经由雾化组件到吸气口3的气流路径，以将气溶胶传递到吸气口3。换言之，雾化器100在使用时，吸吮吸嘴组件11在外壳体12内产生负压，外部大气通过进气口14进入至电极132的进气孔133内，然后沿着图6中箭头R2所示路径，由电极132的第二壁孔134进气第一承接元件1010的中心孔102；继续沿着图6中箭头R1所示路径，再携带多孔体5生成的气溶胶，依次经第一管状元件8的传输管81，直至吸嘴组件11的出气孔111处被吸食，形成完整的气流通道15。
综上所述，本申请将雾化器100的通孔6设置成由多孔体5的第一端51贯穿或延伸至第二端52。该通孔6包括靠近第一端51的第一区段61、以及靠近第二端52的第二区段62。其中，第二区段62在第二端52处的横截面积大于在靠近第一区段61处的横截面积。因此，多孔体5内部的气溶胶冷凝时能够沿通孔第二区段62外周向下流出，避免多孔体5中通孔6被堵塞，进而影响雾化效果。
现有电子雾化器中用于雾化的液体基质通常呈脂或膏状，其常温粘稠度一般在100000-1000000pa.s。在使用电子雾化器后，液体基质被雾化后其内部雾化组件，例如多孔体，会残留较多的冷凝液。若无特殊结构储存或回收冷凝液，常温状态下会堵塞多孔体。
为解决这一技术问题，本申又一实施例公开了一种电子雾化装置1000。如图1所示，图1是本申请电子雾化装置一实施例立体结构示意图。本申请提供的电子雾化装置1000包括雾化器100，以及为该雾化器供电的电源机构200。电子雾化装置1000可以用于医用或者其他用途。其中，雾化器100可以作为分体式的电子雾化装置1000的一部分，用于将储存于其内的液体基质雾化。电源机构200与雾化器100电连接，其内部可以装载可拆卸的电池，便于用户更换。
以下本申请实施例描述雾化器100的示例性结构。
如图2和图8所示，图2是图1所示的电子雾化装置的雾化器的立 体结构示意图；图8是图2所示的雾化器的剖面结构示意图。该雾化器100包括沿纵向方向相背离的近端1和远端2、吸气口3、储液腔4、多孔体5、加热元件7、第一承接元件1010。雾化器100还包括第二承接元件1110、进气口14、第二管状元件80、吸嘴组件11、外壳12、底座组件13、气流通道15。
其中，吸气口3位于近端1。进气口14位于远端2。吸嘴组件11用于界定雾化器100的近端1。底座组件13用于界定雾化器100的远端2。吸嘴组件11的内部开设空腔，该空腔界定为吸气口3。吸嘴组件11的内部同样开设有空腔，该空腔界定为进气口14。外壳12连接于吸嘴组件11远离近端1的一端，底座组件13与外壳12远离吸嘴组件11的另一端紧密连接。
储液腔4用于存储液体基质。液体基质可以是含有药物的液体或其他液体基质，通常其理化形状不同。例如，一些液体基质的粘度较大，而其他液体基质的粘度较小。
第二管状元件80设置于外壳12的内部，且一端容置于吸嘴组件11的内部，另一端容置于底座组件13的内部。第二管状元件80的内壁用于界定气流通道15。气流通道15位于进气口14与吸气口3之间。
外壳12的内壁和第二管状元件80的外壁界定储液腔4。吸嘴组件11内部设置有密封圈111。该密封圈111围设于第二管状元件80的外周，且一端容置于吸嘴组件11远离近端1的一端，另一端延伸至外壳12内部且与外壳12内壁抵靠，进而使得第二管状元件80的上端83被抵靠，防止发生不必要的位移。外壳12的底端呈弯折状，且边缘延伸至第二管状元件80的下端84，进而支撑第二管状元件80的下端84的外周，使其被固定。因此，第二管状元件80的外壁和外壳12的内壁形成密闭的储液空间4。外壳12可以设置为透明玻璃或者树脂等材质，以方便用户观测其内的液体基质的含量，待液体基质消耗完后可以补充。
请继续结合图9和图10，其中，图9是图8所示的雾化器的部分放大示意图；图10是图8所示的雾化器的第一承接元件的立体结构示意图。第一承接元件1010位于多孔体5和远端2之间，以用于承接通孔6的气溶胶冷凝液。第一承接元件1010设有至少一个导流结构1011。液体基质被雾化后形成的气溶胶在温度降低之后，易在多孔体5外周形成冷凝液。该导流结构1011被布置成由第一承接元件1010朝向通孔6延伸，用于将通孔6内的气溶胶冷凝液朝第一承接元件1010进行引导。在本实施例中，第一承接元件1010具体设置在第二管状元件80的靠近下端84的内壁。在其他实施例中，第一承接元件1010也可以设置于底 座组件13的内部。在本实施例中，至少一个导流结构1011的数量是一个。当冷凝液的粘度较小流动性较强时，可以选择仅设置一个导流结构1011。在其他实施例中，少一个导流结构1011的数量可以是多个，例如两个，三个，四个等。多个导流结构1011被布置为沿第一承接元件1010的纵向相间隔。当冷凝液的粘度较大流动性较差时，可以选择设置多个导流结构1011，以提高引导效率。
导流结构1011被构造成是由第一承接元件1010朝向通孔6延伸的柱状。例如，导流结构1011的形状可以是方柱状、圆柱状、椭柱状等。在一些实施例中，导流结构1011的横截面积可以保持一致。在其他实施例中，导流结构1011的横截面积可以设置为朝通孔6的方向逐渐变小，以利于引导冷凝液迅速流动。在本实施例中，导流结构1011的形状为横截面积一致的方柱体。
导流结构1011沿雾化器100的纵向方向的投影部分位于通孔6内。由于冷凝液沿多孔体5的内壁流动时，部分悬挂于通孔6内，将导流结构1011布置成沿雾化器100的纵向方向的投影部分位于通孔6利于承接延伸至通孔6的冷凝液。
在本实施例中，导流结构1011与多孔体5是不接触的，以形成间隙。沿雾化器100的纵向方向，导流结构1011与通孔6的第二端52之间保持有间隙以界定形成毛细通道，以通过毛细作用将气溶胶冷凝液由通孔6的第二端52吸附至导流结构1011上。导流结构1011与通孔6的第二端52之间的间隙介于0.2～2mm。例如，间隙的距离为0.2mm、0.3mm、0.5mm、0.8mm、1.0mm、1.5mm、1.8mm、2.0mm。在其他实施例中，导流结构1011可以被布置成直接与多孔体5接触，也即导流结构1011与多孔体5之间无间隙。如此，冷凝液可以直接沿导流结构1011流动。例如，当液体基质的粘度较大时，可以选择将导流结构1011布置成直接与多孔体5接触。
第一承接元件1010毗邻多孔体5的表面上界定有凹槽1012，以用于容纳或保持气溶胶冷凝液。气溶胶形成的冷凝液沿着朝向远端2的方向流出，在导流结构1011的引导下流入凹槽1012，避免多孔体5被冷凝液堵塞而影响进一步的雾化效果。
第一承接元件1010上设有与通孔6基本同轴布置的第一气孔1013；且第一气孔1013至少部分的直径小于通孔6至少部分的直径。第一气孔1013在使用中供空气进入经由该第一气孔1013进入通孔6。如此，当凹槽1012内的冷凝液过多而溢出时，可以沿第一气孔1013向下流，防止堵塞第一承接元件1010的第一气孔1013。第一气孔1013的横截面 积沿远离多孔体5的方向逐渐变大。例如，第一气孔1013的形状可以是喇叭口型、锥型等。喇叭口型或锥型等形状有利于加快冷凝液的流速。
第一承接元件1010还开设有两个避让槽，第一引线72和第二引线73分别通过该两个避让槽伸入底座组件13。
请继续结合图8、图9和图11所示，其中，图11是图8所示的雾化器的第二承接元件的立体结构示意图。第二承接元件1110位于第一承接元件1010和远端2之间，以用于承接由第一气孔1013流出的气溶胶冷凝液。沿雾化器100的纵向方向，第二承接元件1110与第一承接元件1010间隔布置。在本实施例中，第二承接元件1110具体设置在底座组件13的内部。在其他实施例中，第二承接元件1110也可以设置于第二管状元件80的靠近下端84的内壁。换言之，第一承接元件1010和第二承接元件1110均设置于第二管状元件80的靠近下端84的内壁，或者第一承接元件1010和第二承接元件1110均设置于底座组件13的内部。
可选地，第二承接元件1110毗邻第一承接元件1010的表面上界定有第二凹腔1111，以用于容纳或保持气溶胶冷凝液。气溶胶形成的冷凝液沿着朝向远端2的方向流出，在导流结构1011的引导下流入凹槽1012，当凹槽1012内的冷凝液溢出时，沿着第一气孔1013的周向继续流动。第二凹腔1111被设置成与第一承接元件1010朝向远端的一侧对准，则第一气孔1013流出的冷凝液被第二凹腔1111承接，对于避免多孔体5被冷凝液堵塞起到双重保障的作用。
第二承接元件1110上设有与第一气孔1013基本同轴布置的第二气孔1112；且第二气孔1112至少部分的直径小于第一气孔1013至少部分的直径。第二气孔1112在使用中供空气进入经由该第二气孔1112进入第一气孔1013，进而进入通孔6。如此，当凹槽1012内的冷凝液过多而溢出时，可以沿第一气孔1013向下流至第二凹腔1111，防止堵塞第一承接元件1010的第一气孔1013。第二气孔1112的横截面积沿远离第一承接元件1010的方向逐渐变大。例如，第二气孔1112的形状可以是喇叭口型、锥型等。喇叭口型或锥型等形状有利于加快冷凝液的流动。
第二承接元件1110同样开设有两个避让部，该两个避让部与第一承接元件1010开设的两个避让槽一一对准，第一引线72和第二引线73分别通过该两个避让槽和两个避让部伸入底座组件13。
如图8和图9所示，底座组件13内壁设置有绝缘环131，绝缘环131内壁套设有电极132。其中，第一引线72和第二引线73可分别与电极132和导电的底座组件13连接，以在通电后发热将液体基质雾化 形成气溶胶。电极132和底座组件13用于电连接电源机构的正极和负极，绝缘环131用于将电极132和底座组件13绝缘，防止短路。
综上所述，本申请将雾化器100通过设置第一承接元件1010以承接通孔6内的气溶胶冷凝液。且第一承接元件1010设有至少一个导流结构1011，该导流结构1011被布置成由第一承接元件1010朝向通孔6延伸，能够将通孔6内的气溶胶冷凝液朝第一承接元件1010进行引导，进而避免通孔被堵塞。
区别于现有技术的情况，本申请提供的雾化器通过设置第一承接元件以承接通孔的气溶胶冷凝液；且，该第一承接元件设有至少一个导流结构，该导流结构被布置成由第一承接元件朝向通孔延伸。该导流结构能够将通孔内的气溶胶冷凝液朝第一承接元件进行引导，进而避免通孔被堵塞。
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。
