具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
现有的雾化装置的雾化吸嘴在由用户进行抽吸时，雾化装置产生雾化喷雾的过程中，在气道的内壁容易出现喷雾凝结而形成冷凝液的问题，用户抽吸的过程中可能会抽到冷凝液，从而影响用户体验。对此，本申请提供一种雾化吸嘴及雾化装置，用以解决此问题。具体的，本申请的雾化吸嘴及雾化装置形成与导气通道连通的第一开孔，在进行抽吸时，将空气从第一开孔的位置处吸入，使空气在管体内壁和雾化喷雾之间形成气膜，从而阻隔雾化喷雾，以减少雾化喷雾撞击吸嘴壁而产生的冷凝液。下面结合附图和实施例对本申请进行详细的说明。
请参见图1，为本申请雾化吸嘴的第一实施例的结构示意图。本实施例提供的雾化吸嘴包括：气道部12及吸嘴部。其中，吸嘴部包括管体11，管体11具有导气通道111。气道部12安装于管体11的一端，气道部12具有气道入口13，气道部12的气道入口13与管体11的导气通道111连通。其中，气道入口13用于导入雾化喷雾，并将雾化喷雾输送至导气通道111中。
结合图2，图2为本申请雾化吸嘴的第一实施例的立体结构示意图，其中，气道部12安装于管体11的一端时，部分抵接于导气通道111的一端，并遮挡部分导气通道111。气道部12遮挡导气通道111的位置处设置有与导气通道111连通的第一开孔14。可选地，气道部12具有抵接导气通道111的一端并遮挡部 分导气通道111的壁部123，第一开孔14位于壁部123上，并与导气通道111连通。
由于雾化喷雾中含有水汽，容易在导气通道111的内壁形成冷凝液，设置第一开孔14，第一开孔14通入空气，在雾化吸嘴进行抽吸时，即在管体11远离气道部12的一端进行抽吸时，在雾化吸嘴内部形成气压差，在气压差的作用下，使得第一开孔14中进入的空气附着在导气通道111的内壁，并在导气通道111的内壁形成高速气膜，进而将雾化喷雾与导气通道111的内壁隔离，以减少雾化喷雾在导气通道111的内壁形成的冷凝液。在雾化吸嘴未进行抽吸时，雾化吸嘴内部没有气压差，导气通道111的内壁没有高速气膜。
可选地，为了使导气通道111的内壁均附着有高速气膜，在一具体实施例中，第一开孔14的数量至少为一个，且至少一个第一开孔14沿壁部123周向排布。
请一并参见图3，为本申请雾化吸嘴的气道部的第一开孔的结构示意图。气道部12包括遮挡导气通道111的壁部123。第一开孔14位于壁部123，且与导气通道111连通。如图3所示，第一开孔14的数量为多个，其均匀的沿壁部123周向排布。在一具体实施例中，第一开孔14的形状不做限定，其只要能够在抽吸时使空气进入导气通道111即可。在一可选实施例中，第一开孔14的形状可以为方形、圆形、三角形中任意一种或任意组合。
进一步的，在设置第一开孔14时，当对其大小进行合理规划时，可实现第一开孔14中进入的空气能够在导气通道111的内壁形成完全覆盖导气通道111的内壁的高速气膜。
请继续参见图1，本申请的雾化吸嘴的气道部12包括第一气道部121、第二气道部122及连接第一气道部121与第二气道部122并遮挡部分导气通道111的壁部123。其中，气道入口13主要位于第一气道部121中，且与导气通道111连通，第二气道部122套设在吸嘴部的管体11的外侧。在一具体实施例中，壁部123抵接导气通道111的一端，在另一实施例中，壁部123还可以与导气通道111的一端具有间隙，其只要能够保证雾化喷雾不会外泄即可。
可选的，第一气道部121还包括通气部124及连接部125，其中，连接部125位于壁部123远离第二气道部122的一侧，通气部124位于连接部125远离壁部123的一侧。其中，连接部125的直径小于通气部124的直径，连接部125 与通气部124连接的位置处形成卡接口126，卡接口126用于卡接喷雾产生装置(图未示)。进一步地，请结合图2及图7，卡接口126的位置处形成有综合气道31，空气从综合气道31进入第一开孔14，进而从第一开孔14进入至导气通道111，在抽吸时，产生压力差后，在压力差的作用下在导气通道111的内壁形成高速气膜72。如图7所示，高速气膜72将雾化喷雾71与导气通道111隔离，进而减少雾化喷雾71在导气通道111形成的冷凝液。
可选地，在一实施方式中，气道部12中的第一气道部121、第二气道部122及连接第一气道部121及第二气道部122的壁部123一体成型。在另一实施方式中，气道部12中的第一气道部121、第二气道部122及连接第一气道部121及第二气道部122的壁部123还可以通过焊接等工艺连接而成。
可选的，气道部12的第二气道部122套设于吸嘴部的管体11的外侧。具体的，在一实施方式中，气道部12与管体11可以一体成型设计。在另一实施方式中，第二气道部122还可以通过匹配的方式套设于吸嘴部的管体11的外侧，为了防止雾化喷雾外泄，在将第二气道部122套设于吸嘴部的管体11的外侧时可使用过盈配合的方式进行设置。
本实施例提供的雾化吸嘴，在遮挡导气通道111的壁部123设置与导气通道111连通的第一开孔14，在管体11有抽吸动作时，雾化喷雾从气道入口13进入导气通道111的同时，空气从第一开孔14的位置处进入导体通道111，在气压的作用下，从第一开孔14进入的空气会在导气通道111的内壁形成高速气膜，从而将雾化喷雾与导气通道111的内壁隔离，进而防止雾化喷雾在导气通道111的内壁形成冷凝液。
请参见图4，为本申请雾化吸嘴的第二实施例的结构示意图。与上述图1所示的第一实施例相比，区别在于：本实施例在通气部124的外侧设置有第二开孔21。第二开孔21用于加快雾化喷雾的排出速度，以进一步防止雾化喷雾在导气通道111的内壁形成冷凝液。
可选的，第二开孔21包括进气部211及导气部212，具体地，进气部211在通气部124的周围沿平行于壁部123的方向设置，导气部212沿平行于气道入口13的方向设置，且导气部212连接进气部211位于通气部124内的一端。其中，空气自进气部211中进入，并从导气部212流向导气通道111。
可选的，请参见图5，为本申请的雾化吸嘴的立体结构示意图。如图所示， 第二开孔21位于通气部124，第一开孔14位于连接第一气道部121及第二气道部122的壁部123。在一具体实施例中，当吸嘴部的管体11产生抽吸力时，雾化喷雾从气道入口13进入，空气从第二开孔21及第一开孔14的位置进入。请结合图6，为本申请雾化吸嘴仰视图。如图所示，第一开孔14的位置较之第二开孔21中的导气部212更靠近于吸嘴部的管体11的导体通道111的内壁。因此，当进行抽吸时，在气压的作用下，第一开孔14进入的空气在吸嘴部的管体11的导体通道111的内壁形成高速气膜，进而将从气道入口13进入的雾化喷雾与导体通道111的内壁隔离，以减少雾化喷雾与导体通道111的内壁形成的冷凝液。进一步的，设置第二开孔21，在进行抽吸时，第二开孔21进入空气，该空气加快自气道入口13进入的雾化喷雾在导气通道111中的排出速度，进一步防止雾化喷雾与导体通道111的内壁形成冷凝液。
进一步地，连接部125与通气部124连接的位置处形成卡接口126，卡接口126用于卡接喷雾产生装置(图未示)。进一步地，请结合图5及图7，卡接口126的位置处形成有综合气道31，空气从综合气道31进入第一开孔14及第二开孔21，进而从第一开孔14进入至导气通道111，在抽吸时，产生压力差后，在压力差的作用下在导气通道111的内壁形成高速气膜72。如图7所示，高速气膜72将雾化喷雾71与导气通道111隔离，进而减少雾化喷雾71在导气通道111内壁形成冷凝液。空气从第二开孔21进入导气部212，在进入导气通道111形成第二气流73，第二气流73加快雾化喷雾71的排出速度。
可选的，在本实施例中，第二开孔21的导气部212可以为方形、圆形、三角形中任意一种或任意组合。第二开孔21的进气部211同样可以为方形、圆形、三角形中任意一种或任意组合，具体不做限定，其只要能够将空气引入导气部212，进而进入导气通道111中即可。
在一实施例中，第二开孔21为至少一个，且其在通气部124的外侧周向排布。
在一实施例中，第二开孔21可以与第一开孔14的位置对应设置，在另一实施例中，第二开孔21还可以与第一开孔14的位置错开设置。具体的，为了减少进入第一开孔14及第二开孔21的空气形成的气流之间的相互影响，第二开孔21与第一开孔14的位置错开设置。
在一实施例中，在设置第一开孔14及第二开孔21时，为保证第一开孔14 进入的空气在导气通道111的内壁形成高速气膜，进而实现将雾化喷雾与导气通道隔离，并实现自第二开孔21进入的空气能够加快雾化喷雾的排出速度，第二开孔21及第一开孔14形成的气流具有速度差。在一具体实施例中，第一开孔14形成的气流的流速要大于第二开孔21形成的气流的流速，以此能在实现减少冷凝液的效果的同时，减少对雾化喷雾的传输方向的影响。
具体的，第一开孔14及第二开孔21形成的气流的流速与开孔的尺寸相关，开孔的尺寸越大，流速越快。因此，在一具体实施方式中，为实现第一开孔14形成的气流的流速要大于第二开孔21形成的气流的流速，设置第一开孔14的尺寸大于第二开孔21的尺寸，或者在另一实施例中，设置第一开孔14的数量大于第二开孔21的数量。
请参见图7，为本申请雾化吸嘴的第一开孔及第二开孔中的气体仿真示意图。如图所示，第一开孔14中进入的空气在进行抽吸而产生气压差，在气压差的作用下在导气通道111的内壁形成高速气膜72，雾化喷雾71呈喇叭状，高速气膜72将雾化喷雾71与导气通道111隔离，以减少雾化喷雾71在导气通道111的内壁形成冷凝液。第二开孔21进入的空气在导气通道中形成第二气流73，第二气流73沿雾化喷雾71形成的喇叭状的外边沿进行流动，以加快雾化喷雾71的排出速度。
请参见图8，为本申请雾化装置的一实施例的结构示意图。雾化装置61包括喷雾产生装置63及雾化吸嘴62。其中，喷雾产生装置63用于产生喷雾。雾化吸嘴62为上述图1至图5所示的雾化吸嘴，在此不再赘述。雾化吸嘴62与喷雾产生装置63连接。具体的，喷雾产生装置63通过雾化吸嘴62中的通气部124与连接部125形成的卡接口126卡接在雾化吸嘴62上，以使喷雾产生装置63产生的喷雾自气道入口13进入吸嘴部。
在一具体实施方式中，本申请提供的雾化装置61可应用于雾化吸入治疗行业，雾化吸入治疗是通过不同的装置把药物以气溶胶的形式输出并随呼吸进入体内。气溶胶是指固体微粒或液体微粒混悬于空气或空气中组成的分散体系，可以随空气流动传输。在雾化吸入治疗中，选择合适的装置及正确的吸入方法对治疗效果有很大影响。本申请提供的雾化装置61具体可应用于如定量压力气雾剂、干粉吸入剂、喷射雾化器等设备。
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。
