参阅图1，本申请一实施例中，提供一种吸入装置200，包括雾化结构100及吸管210，吸管210的一端***雾化结构100内，吸管210的另一端用于***药剂瓶300内，当用户使用吸入装置200时，药剂瓶300内的气溶胶生成基质通过吸管210流向雾化结构100，然后通过雾化结构100雾化为气溶胶供用户吸入使用。
参阅图2-图3，一些实施例中，雾化结构100包括支架组件10和雾化组件30，雾化组件30安装于支架组件10内，且包括微流晶体32和包围微流晶体32的密封件34，微流晶体32具有相互连通的进液侧321和出液侧323，密封件34具有与出液侧323位于同一侧的顶面341。其中，微流晶体32为内部具有多条微流通道的结构件，液态的气溶胶生成基质在压力的作用下由进液侧321到出液侧323，流经微流晶体32内部后便可被雾化形成气溶胶。微流晶体32通常可以采用高分子材料、金属、陶瓷、玻璃或硅基材料中的至少一种制成。
并且，支架组件10朝向顶面341凸出设置凸缘11，密封件34被凸缘11挤压于支架组件10内，以从微流晶体32的出液侧323挤压密封件34，进而使密封件34向内变形，进而密封密封件34自身包围的微流晶体32，防止气溶胶生成基质流向微流晶体32时漏液。可以理解，上述设置方式的好处主要包括如下方面。一方面，凸缘11能使密封件34产生形变，形变能将凸缘11指向密封件34的轴向压力转换为包围微流晶体32四周的压力，即将轴向压力转换为与之垂直的平面方向的压力，提高微流晶体32固定的稳定性及密封效果，并同时使得压力均匀分散，避免压力集中损坏微流晶体32。另一方面，凸缘11设置于出液侧323的一侧，在装配过程中可以最后细微调整相关组件的配合关系，避免在装配过程中出现不一致情形需要重新组装整个结构的情形，提高了装配的便利性及一致性。
参阅图4，进一步地，凸缘11为圆形或者椭圆形，凸缘11没有尖角，以对密封件34均匀地施加挤压力，使密封件34能够均匀变形且密封固定。
参阅图3-图6，一些实施例中，密封件34内形成有安装通道343，微流晶体32套设于安装通道343内，且安装通道343具有分别对应进液侧321和出液侧323的第一开口42和第二开口44，如此通过密封件34上的安装通道343安装微流晶体32，且安装通道343具有第一开口42和第二开口44，气溶胶生成基质通过第一开口42流向微流晶体32内被雾化后，从第二开口44喷出。
一些实施例中，第一开口42的至少部分内壁与微流晶体32之间预留有第一间隙(423)，相当于第一开口42的至少部分内壁与微流晶体32不直接贴合，如此在第一开口42处为密封件34预留第一间隙(423)，当密封件34受到凸缘11的挤压向内形变且与微流晶体32紧密贴合时，第一间隙为密封件34在轴向上的形变预留空间，防止密封件34在向内形变的同时凸出进液侧321而造成其他问题，例如堵塞进液侧321的进液口，如此保证雾化效果的同时保证密封效果。
进一步地，微流晶体32为长方体，微流晶体32厚度方向的相对两侧分别为进液侧321和出液侧323，微流晶体32沿宽度方向的两侧中的至少一侧预留有第一间隙(423)，即微流晶体32在进液侧321的长边旁预留第一间隙(423)，密封件34围绕微流晶体32向靠近微流晶体32的内部变形时，密封件34对应微流晶体32长边的一侧形变较大，进而对应设置第一间隙(423)，来有效保证密封效果。或者，微流晶体32沿宽度方向相对两侧中的至少一侧预留有第一间隙，且微流晶体32沿长度方向相对两侧中的至少一侧预留有第一间隙，即在微流晶体32的长边旁及短边旁均设置第一间隙，来进一步保证密封效果。
具体地，第一开口42包括第一主开口421及均与第一主开口421连通的两个第一辅助开口423，第一主开口421与进液侧321对应，两个第一辅助开口423沿宽度方向位于第一主开口421的相对两侧，如此在微流晶体32进液侧321的两个长边旁边均设置第一
辅助开口423，第一辅助开口423被构造为第一间隙，通过第一辅助开口423预留密封件34向内形变时在轴向上所需的形变空间。
一些实施例中，第二开口44的至少部分内壁与微流晶体32之间预留有第二间隙(443)。相当于第二开口44的至少部分内壁与微流晶体32不直接贴合，如此在第二开口44处为密封件34预留第二间隙(443)，当密封件34受到凸缘11的挤压向内形变且与微流晶体32紧密贴合时，第二间隙为密封件34在轴向上的形变预留空间，防止密封件34在向内形变的同时凸出出液侧323，如此保证雾化效果的同时保证密封效果。
进一步地，密封件34可以采用硅胶等柔性材质。如图2-图6所示，密封件34为圆台形状。进一步地，圆台形密封件34的第二开口44开设于半径较大的一个底面，第一开口42开设于半径较小的一个底面。可以理解，圆台形密封件34更有利于装配，同时密封压力更加均匀。
进一步地，微流晶体32为长方体，微流晶体32厚度方向的相对两侧分别为进液侧321和出液侧323，微流晶体32沿宽度方向相对两侧中的至少一侧预留有第二间隙(443)，即微流晶体32出液侧323的长边旁预留第二间隙，密封件34围绕微流晶体32向靠近微流晶体32的内部变形时，密封件34对应微流晶体32长边的一侧形变较大，进而对应设置第二间隙，来有效保证密封效果。或者，微流晶体32沿宽度方向相对两侧中的至少一侧预留有第二间隙，且微流晶体32沿长度方向相对两侧中的至少一侧预留有第二间隙，即在微流晶体32出液侧323的长边旁及短边旁均设置第二间隙，来进一步保证密封效果。
具体地，第二开口44包括第二主开口441及均与第二主开口441连通的四个第二辅助开口443，第二主开口441与出液侧323对应，四个第二辅助开口443中的两个第二辅助开口443沿宽度方向分别位于第二主开口441的相对两侧，四个第二辅助开口443中的另外两个第二辅助开口443沿长度方向分别位于第二主开口441的相对两侧，第二辅助开口443被构造为第二间隙。如此，在微流晶体32出液侧323的两个长边及两个短边旁边
均设置第二辅助开口443，第二辅助开口443被构造为第二间隙，通过第二辅助开口443预留密封件34向内形变时在轴向上所需的形变空间。
一些实施例中，支架组件10包括支架50、支撑模块70及盖体80，支架50上开设有安装腔51，支撑模块70设于安装腔51内，雾化组件30安装于支撑模块70内，以通过支撑模块70固定雾化组件30。并且，盖体80与支架50可拆卸连接并与支撑模块70位于出液侧323的一端抵接，且支撑模块70上设置有凸缘11，支撑模块70用于固定雾化组件30的同时，具有挤压密封件34的凸缘11，且盖体80盖设于支架50上时，与支撑模块70位于出液侧323的一端抵接，将支撑模块70挤压于支架组件10内，进而使支撑模块70上的凸缘11挤压密封件34，有效密封设于密封件34内的微流晶体32。
可选地，盖体80与支架50螺纹连接，方便安装及拆卸。
进一步地，支撑模块70包括第一支撑件72和第二支撑件74，第一支撑件72套设于安装腔51内，即第一支撑件72装配于支架50上，且第一支撑件72上开设有安装槽721，雾化组件30安装于安装槽721内，即套设于第一支撑件72内，第二支撑件74套设于第一支撑件72上，且面向密封件34的顶面341，并被夹持于盖体80和第一支撑件72之间。也就是说，雾化组件30安装与第一支撑件72的安装槽721内，第二支撑件74盖设于第一支撑件72上并通过盖体80的施压而压紧雾化组件30。并且，第二支撑件74面向顶面341的一侧设置有凸缘11，以通过第二支撑件74上的凸缘11对密封件34的顶面341施加挤压力，保证密封效果。
一些实施例中，第一支撑件72、第二支撑件74及盖体80上分别开设有第一过孔723、第二过孔741及喷射口82，第一过孔723与进液侧321连通，第二过孔741与出液侧323连通，喷射口82与第二过孔741连通，气溶胶生成基质通过第一过孔723进入微流晶体32后，从第二过孔741及喷射口82喷出，且形成雾化后的气溶胶。
进一步地，雾化结构100还包括过滤件94，过滤件94设于第一过孔723内，以对流
向微流晶体32的气溶胶生成基质进行过滤。
一些实施例中，雾化结构100还包括垫片92，垫片92设置于密封件34与第一支撑件72之间，如此垫高密封件34，防止密封件34包围的微流晶体32与第一支撑件72刚性接触，防止安装盖体80时，微流晶体32在向下移动并与第一支撑件72产生刚性挤压而损坏。
上述吸入装置200中，吸管210的一端***支架组件10内并与微流晶体32的进液侧321连通，吸管210的另一端用于***药剂瓶300内，药剂瓶300内的气溶胶生成基质通过吸管210流向微流晶体32内被雾化后喷出，且密封件34受到凸缘11的挤压后向内变形，以有效密封微流晶体32，防止气溶胶生成基质漏液。
雾化结构100的装配过程可以为：第一步，将包括第一支撑件72、雾化组件30等部件装配在支架50所形成的安装腔51*第二步，将第二支撑件74设置有凸缘11的一侧安装于顶面341；第三步，将盖体80于抵靠安装于第二支撑件74的另一侧，并提供逐步施压。上述步骤中，可以直接在第二步中调整相关部件的配合关系，避免调整第一步中已经安装好的部件，提高了装配的便利性及一致性。
一些实施例中，本申请一实施例中，提供一种上述雾化结构100。雾化结构100包括支架组件10和雾化组件30，雾化组件30安装于支架组件10内，且包括微流晶体32和包围微流晶体32的密封件34，微流晶体32具有相互连通的进液侧321和出液侧323，密封件34具有与出液位于同一侧的顶面341。其中，微流晶体32为内部具有多条微流通道的晶体件，气溶胶生成基质由进液侧321到出液侧323，流经微流晶体32内部后便可被雾化。
并且，支架组件10朝向顶面341凸出设置凸缘11，密封件34被凸缘11挤压于支架组件10内，以从微流晶体32的出液侧323挤压密封件34，进而使密封件34向内变形后有效密封自身包围的微流晶体32，防止气溶胶生成基质流向微流晶体32时漏液。
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。
