本申请涉及雾化技术领域，特别是涉及一种雾化器及电子雾化装置。
背景技术
电子雾化装置通常包括储液腔、气道管、雾化芯和电芯，电芯给雾化芯供电，雾化芯用于雾化储液腔的气溶胶基质，气道管则进一步将经雾化芯雾化后形成的气溶胶输送至电子雾化装置外部，以供用户吸食。然而，在雾化器中，由于雾化器体积限制，气道管分隔形成的两个储液腔之间联通空间十分有限，而气溶胶基质往往为粘性液体，经常会吸附在联通空间的两侧进而堵塞两个储液腔之间的联通通道，导致两个储液腔出液不平衡，气液差不断增加，甚至产生一侧储液腔液体尚未流出，另一侧储液腔液体已经流完的极端现象，严重影响用户的使用体验。

为解决现有雾化器中存在的两侧储液腔出液不平衡的问题，本申请提出一种雾化器及电子雾化装置。电子雾化装置可用于液态基质的雾化，通常包括相互连接的雾化器和电芯。请参阅图1，图1是本申请雾化器10一实施例的结构示意图。雾化器10用于存储液态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，液态气溶胶生成基质可以是药液、植物草叶类液体等液态基质；雾化器10具体可用于不同的领域，比如，医疗、电子气溶胶化等。电芯(未示出)用于为雾化器10供电，以使得雾化器10能够雾化待雾化基质形成气溶胶。雾化器10与电芯可以是一体设置，也可以是可拆卸连接，可根据用户实际需要进行具体设定，本申请在此不做限定。请参阅图2，图2是图1所示雾化器10沿AA视向的剖面结构示意图。
本申请雾化器10设置有外壳11、顶盖12和储液腔13。外壳11包括壳体14和气道管15，壳体14可用于容纳和保护雾化器10内的零部件；气道管15设置于壳体14内，并且气道管15的一端与壳体14相连 接，气道管15可用于将雾化器10内产生的气溶胶输送至壳体14外部以供用户吸食。
顶盖12连接壳体14的内壁和气道管15的另一端，并界定出储液腔13，储液腔13可用于存储液态气溶胶生成基质。在一些实施例中，顶盖12设有第一液孔17和第二液孔18，第一液孔17和第二液孔18分设于气道管15的两侧，且均连通储液腔13。第一液孔17和第二液孔18的设置可使得储液腔13内存储的气溶胶生成基质顺利通过顶盖12，并随后进入雾化芯19中进行雾化，以形成气溶胶，气溶胶随后经由气道管15输出至壳体14外部，以供用户吸食。
请结合参阅图1至图6，图3是图1所示雾化器沿BB视向的剖面结构示意图，图4是图3所示雾化器中C区域一实施例的放大结构示意图，图5是本申请外壳和储液腔一实施例的仰视结构示意图，图6是本申请外壳和储液腔另一实施例的仰视结构示意图。
本实施例中，壳体14沿气道管15的轴线上的横截面呈椭圆状，可将该椭圆的短轴延伸方向定义为壳体14的第一方向A，将该椭圆的长轴延伸方向定义为壳体14的第二方向B，第一方向A和第二方向B向垂直。
可选地，壳体14沿气道管15的轴线上的横截面还可以呈矩形状，可将该矩形的宽度方向定义为第一方向，将该矩形的长度方向定义为第二方向。
通常来讲，雾化器10的储液腔13沿第一方向A上的宽度尺寸a小于等于7.0mm。
例如，壳体14的横截面呈椭圆状，其在各处的宽度尺寸a不相同，储液腔13沿第一方向A上的宽度尺寸a小于等于7.0mm，可认为各处的宽度尺寸a中的最大宽度尺寸小于等于7.0mm。例如，最大宽度尺寸a可以是4.6mm、4.7mm、4.8mm、4.9mm、5.0mm、5.2mm、5.4mm、5.6mm、5.8mm、6.0mm、6.2mm、6.4mm、6.6mm、6.8mm或7.0mm等。
由于雾化器10的体积结构十分有限，为保证气道管15能够尽可能多地输送气溶胶，本申请将气道管15设置于储液腔13沿第一方向A上 的最大宽度尺寸a处。
本实施例中，气道管15的管孔在最大宽度尺寸a处的沿第一方向A的宽度尺寸d大于等于1.6mm，以减小吸阻而利于用户抽吸，并可充分保证用户的每口抽吸量。
例如，宽度尺寸d为1.6mm、1.7mm、1.8mm、1.9mm、2.0mm、2.1mm或2.2mm等。
在一些实施例中，气道管15的管孔为圆孔或椭圆孔，当然，气道管15的管孔也可以呈其他形状，只要能够输送气溶胶即可，本申请在此不做具体限定。其中，当气道管15的管孔为椭圆孔时，椭圆孔的长轴沿第二方向B设置，椭圆孔的短轴沿第一方向A设置且位于最大宽度尺寸a处。这一设置使得气道管15在有限的空间下能够实现孔径面积最大化，进而有利于气溶胶在气道管15中的快速输送，并利于保证给用户供给充足的气溶胶量，以避免因输送速度过慢导致大量气溶胶在气道管15中滞留，从而使得温度较高的气溶胶在与温度较低的气道管15管壁相接触时析出大量冷凝液而产生的漏液现象。
在本申请中，气道管15将储液腔13沿第二方向B划分成第一腔22和第二腔23，第一腔22和第二腔23通过气道管15和壳体14之间的间隙24连通，从而使得储液腔13的第一腔22和第二腔23之间可以相互进行气体交换和流通，以实现第一腔22和第二腔23之间的气液平衡，避免一侧腔体下液较快，另一侧液体下液缓慢而使得两侧腔体中液体的高度差不断增加，甚至出现一侧腔体无液体，另一侧腔体中仍存放大量液体的极端现象。
而结合储液腔13的最大宽度尺寸a小于等于7.0mm，且气道管15在最大宽度尺寸a处的宽度尺寸d大于等于1.6mm，再加上气道管15的壁厚，则气道管15和壳体14之间的间隙24的尺寸及其有限，极容易导致被具有粘性的气溶胶基质在间隙24处形成液膜封堵。
请参阅图4至图6，在壳体14的第一方向A上，气道管15具有相背的两侧，其中至少一侧设置有凹部25，凹部25使得气道管15在其周围的部分相对不低于凹部25所在区域，进而可增大凹部25所在区域与 壳体14在第一方向A上的间隙24，以使得第一腔22和第二腔23之间流体输送更为顺畅和高效，极大程度上保证两侧储液腔13之间的气液平衡，并可避免气道管15和壳体14之间因间隙24过小而形成液膜的状况发生。
进一步地，在气道管15朝向顶盖12的端部设置有凹部25，凹部25使得气道管15和壳体14之间在最大宽度尺寸a处的最大间隙尺寸b大于等于0.75mm。本申请凹部25的设置，可使得在雾化器10体积限制下，最大化第一腔22和第二腔23之间通过气道管15和壳体14连通的间隙24，以使得第一腔22和第二腔23之间流体输送更为顺畅和高效，极大程度上保证两侧储液腔13之间的气液平衡，并且还可避免在某些情形下，储液腔13中液体吸附在气道管15和壳体14上并形成液膜，堵住气道管15和壳体14上之间的间隙24，从而导致两侧储液腔13流体输送受阻等情况发生。
在一些实施例中，凹部25为切削气道管15的外壁形成的斜平面、平面或曲面，当然，凹部25也可以设置为其它结构，只要能够实现在雾化器10体积限制下，气体能够在第一腔22和第二腔23之间通过气道管15和壳体14连通的间隙24进行交换和流通即可，本申请在此不做具体限定。
其中，如图5所示，凹部25为切削气道管15的外壁形成的斜曲面，该曲面绕气道管15的轴线设置。如图6所示，凹部25为切削气道管15的外壁形成的斜平面，该斜平面相对气道管15的轴线呈倾斜设置。可选地，凹部25还可以为切削气道管15的外壁形成的平面，该平面与气道管15的轴线呈平行设置。
可选地，凹部25还可以是在外壳11制作时通过磨具一体形成的，而无需采用切削方式形成。
结合参阅图2、图4至图6，气道管15包括连接的第一管体27和第二管体28，第一管体27的壁厚大于第二管体28的壁厚，凹部25设置于第一管体27连接第二管体28的端部，第二管体28与顶盖12的气雾出口31相装配。
具体而言，管壁较薄的第二管体28更便于与设置在顶盖12上的气雾出口31相装配，具体装配方式可以是插接、卡接等，本申请在此不做具体限定。而将凹部25设置于第一管体27连接第二管体28的端部，则可实现在不改变气道管15输送体积的情况下，增大第一腔22和第二腔23之间通过气道管15和壳体14连通的间隙24。由此，既可保证气溶胶输送效率，又增加了第一腔22和第二腔23之间气体输送的通道体积，避免因液体堵塞联通通道而产生两侧储液腔出液不平衡的问题，进而可提高用户使用体验。
进一步地，凹部25的设置可使得第一管体27的端面与壳体14在最大宽度尺寸处的间隙24的最大间隙尺寸b大于等于0.75mm，且第一管体27的端面与第二管体28相连接。由此，本申请能够极大程度上保证第一腔22和第二腔23之间流体的相互交换与流通，有助于第一腔22和第二腔23之间达到气液平衡，避免第一腔22和第二腔23因间隙24堵塞而无法进行流体流通，进而影响储液腔13出液效果。
在一些实施例中，第一管体27的内壁面和第二管体28的内壁面共面，从而可利用第一管体27相对第二管体28多出的壁厚设置该凹部25，即凹部25设置于第一管体27相对第二管体28凸出的壁厚部；一方面利于气道管15的制作形成，另一方面也利于凹部25的制作形成，有效地降低了制作工艺的难度。
当第一管体27的内壁面和第二管体28的内壁面不共面时，气溶胶在从第二管体28流至第一管体27时，气溶胶极易在转折处与气道管15管壁发生接触，进而导致冷凝液析出量增多，影响出液效果，甚至出现漏液现象。而将第一管体27的内壁面和第二管体28的内壁面设置为共面则可以很好地避免这一现象发生。
在一些实施例中，本申请的雾化器10还包括密封件29，密封件29套设于顶盖12朝向储液腔13的一端，壳体14的内壁面为光滑曲面，顶盖12通过密封件29与壳体14的内壁面相嵌设，且密封件29止挡于第一管体27的端面上，以利用气道管15定位顶盖12和密封件29的位置，避免采用壳体14定位顶盖12和密封件29的位置而导致壳体14的 厚度增厚，即有利于减小雾化器100的在第一方向A的宽度尺寸。
由此，密封件29的设置一方面可使得顶盖12与壳体14的位置相互固定，另一方面还可避免储液腔13内的液体泄漏至壳体14与顶盖12之间的间隙24处，进而可提高雾化器10的使用寿命和使用效果。
区别于现有技术的情况，本申请公开了一种雾化器10及电子雾化装置，受限于雾化器储液腔13沿与第二方向B相垂直的第一方向A上的最大宽度尺寸小于等于7.0mm，也即a小于等于7.0mm，本申请通过将气道管15设置于储液腔13的最大宽度尺寸a处，并且在气道管15朝向顶盖12的端部设置凹部25，进而使得气道管15和壳体14之间在最大宽度尺寸处的间隙24最大尺寸大于等于0.75mm，也即b大于等于0.75mm。由此，本申请可在体积十分有限的雾化器10内，极大程度上加大第一腔22和第二腔23之间联通通道的面积，进而可保证第一腔22和第二腔23之间有足够的空间供流体流通，避免因间隙24过小而导致液体易堵封，从而引发第一腔22和第二腔23出液不平衡，甚至产生一侧有液一侧无液的极端现象。此外，本申请气道管15可以设置为第一管体27和第二管体28两个壁厚不同的管体部分，便于壁厚较小的第二管体28与顶盖12进行装配，在此基础上，本申请将凹部25设置于壁厚较大的第一管体27上，从而可实现在不改变气道管15输送体积的情况下，增加第一腔22和第二腔23之间流体输送的通道体积。
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。
