Description

用于雾化器的触发组件以及雾化器 技术领域
本公开涉及一种用于雾化器的触发组件以及一种雾化器，所述雾化器可例如用于药液的雾化和/或喷射。
背景技术
在相关技术中，雾化器(或称喷雾器)中的容器装有待雾化或喷雾的液体，在该容器相对于喷射组件(例如泵)运动行程中，容器中的液体被雾化并从喷射组件的喷口中喷射出雾化液体。然而，这种雾化器的触发通常不够稳定，以致于液体的雾化和喷射过程时常不够流畅。此外，当该雾化器受到振动或晃动、例如意外滑落时，内部组件可能会不期望地自动运动，使得该雾化器被非人为地自动触发。
雾化器的这种意外的自动触发是不被期望的，其不仅会造成液体的无效浪费，而且可能会在用户未使用的情况下导致雾化器的泄漏、甚至损毁或失效。
发明内容

在本公开的范畴中，“雾化器”(亦称“喷雾器”)指用于雾化液体的设备。通常，雾化器被用于雾化流体(例如药液或类似物)并将被雾化的流体喷射到使用者(例如患者)的一些有待治疗的部位。由于在雾化器中装载的为药液，因此，雾化器的稳定性是尤为重要的。
在相关技术中，可通过机械方式、例如按压开关或旋转开关来操作雾化器。然而，这些开关在雾化器的不使用状态下的锁定可能是不牢靠的。此外，在无需雾化的情况下，雾化器可能会受到一些冲击或晃动，甚至可能会从高处不慎滑落，这些意外不仅使得雾化器中的药液被晃动，而且可能导致雾化器中的部件相对运动而不期望地雾化出液体。可以理解的是，这种不期望的雾化触发是无效的，因为药液在这种情况下并不会到达待治疗的部位，更糟糕的是，这种不期望的雾化触发可能是有害的，因为被意外喷出的雾化液体可能会到处流动并且可能会积在雾化器中，随着时间的推移可能会导致雾化器部件的功能损坏或失效。
有鉴于此，本公开提出一种改进的触发组件，该触发组件被安装到雾化器中，并且优选能够与雾化器的按压开关和/或旋转开关联动，从而通过触发组件在锁止位置和解锁位置之间的转换来控制雾化器的有效触发和/或防止雾化器的无效触发。
在本公开的范畴中，“触发组件”指用于控制雾化器触发的组件，例如能够控制和/或防止雾化器进行雾化或喷射操作的组件。在本公开中，触发组件可例如包括触发环1000和输送管座2000，它们的具体结构将在下文分别借助附图1至附图4、参照附图5至附图8详细说明。另外，触发组件在雾化器中的布置可例如参照附图17至附图19详细说明。
应理解的是，触发组件可不仅仅包括触发环1000和输送管座2000，还可包括其他元件，只要能够实现控制和/或防止触发功能即可。重要的是，触发组件具有(一个或多个)锁止位置与(一个或多个)解锁位置，并且能在它们之间进行切换。
在本公开的范畴中，触发组件的“锁止位置”指使雾化器被锁定的位置，即在没有人为作用的情况下，雾化器不能操作的位置。换句话说，当触发组件位于一“锁止位置”中时，雾化器只有被人为操作才能进行雾化或喷射的操作。在本公开中，触发组件的“锁止位置”还可指触发环1000与输送管座2000实现相互止挡作用的位置。作为一种示例，触发环1000与输送管座2000的“相互止挡”可例如意味着触发环1000阻止输送管座2000的运动、例如竖直方向上的移动，而同时输送管座2000也阻止触发环1000的进一步运动、 例如水平和/或竖直方向的平移。该“锁止位置”将在下文借助附图9至附图11进一步说明。
在本公开的范畴中，触发组件的“解锁位置”是使雾化器不被锁定的位置，即雾化器的可操作位置。换句话说，当触发组件处于“解锁位置”时，雾化器中的部件(例如触发环1000与输送管座2000)能够在不需要人为操作的情况下相对彼此运动，以实现雾化和/或喷射雾化液体的效果。可以理解的是，触发组件的“解锁位置”是相对于上述“锁止位置”的概念，只要雾化器不被锁定，则触发组件即位于解锁位置中。因此，触发组件可例如具有多个“解锁位置”，并且触发组件可在锁止位置与解锁位置之间、或在多个解锁位置之间进行转换。在触发组件的这些转换的过程中，雾化器可实现在初始位置、预触发位置和已触发位置之间的转换。该“解锁位置”将在下文借助附图12至附图14和附图15至附图16进一步说明。
首先，参照附图1至附图4描述根据本公开的一种实施方式的触发环1000。触发环1000可包括环本体1200和第一锁止部(在此，例如为锁止凸起部1100)。锁止凸起部1100从环本体1200的底侧向下突出。可理解的是，虽然附图中示出仅一个从环本体1200的底侧向下突出的锁止凸起部1100，但是锁止凸起部1100的数量和布置并不限制于此。作为示例，触发环1000也可包括多个锁止凸起部1100，例如在其一侧上设置两个或三个锁止凸起部1100，且这些锁止凸起部1100优选圆周等角度阵列地设置，由此可例如实现触发组件的多级的锁止和解锁。例如，在设置有两个锁止凸起部1100的情况下，这两个锁止凸起部1100延环本体1200的圆周呈180°阵列地布置。
作为另一示例，还可在环本体1200的两侧上都设置锁止凸起部1100，在这种情况下，上下两侧的锁止凸起部1100例如是互相错开地设置，并且与设置在触发环1000上下两侧的锁止凹口2100分别配合联动。
在附图中还可见，环本体1200的两侧还分别设置有一些肋结构，用于与其他部件相互连接或配合。例如，在环本体1200上方的两个肋1300形成槽1310，该槽可与雾化器的旋转件相配合，从而限定环本体1200的旋转使得该环本体1200仅进行平移。
锁止凸起部1100可包括第一锁止面1110，其例如是锁止凸起部1100的下斜面。在此可见，第一锁止面1110是在三维方向上均倾斜设置的斜面，亦即该第一锁止面1110不仅相对于水平平面(X’Y’平面)相倾斜，而且也相对竖直平面(Z’Y’平面和X’Z’平面)相倾斜。换句话说，该第一锁止面1110既是触发环1000的径向向外的表面，也是该触发环1000的轴向向外的表面。
作为一种示例，所述第一锁止面1110的法向方向F’与所述触发环1000的第一水平 方向X’的夹角β’在135°至178°的范围内，优选在155°至175°的范围，或夹角β’在150°至189°的范围，尤其优选为168.5°。所述第一锁止面1110的法向方向F’与所述触发环1000的第二水平方向Y’的夹角γ’在65°至90°的范围内，优选在65°至89°的范围，优选在70°至85°的范围，尤其优选为78.5°，并且其中，所述第一锁止面1110的法向方向F’与所述触发环1000的竖直方向Z’的夹角α’在115°至145°的范围内，优选在120°至140°的范围，尤其优选为130°。在本公开中，触发环1000的“第一水平方向X’”、“第二水平方向Y’”分别对应于该触发环1000的径向方向，并且其中，第二水平方向Y’还是触发环1000的触发方向，亦即当使用者按下按压开关时触发环1000受推力而水平移动的方向。触发环1000的“竖直方向Z’”对应于该触发环1000的轴向方向。这些方向X’、Y’和Z’参见附图1至附图3中的坐标系标记出。
在此，第一锁止面1110的这种三维倾斜布置是非常有利的，一方面，当其与设置在锁止凹口2100上的第二锁止面2110相配合时，用于将触发组件从锁止位置切换到解锁位置的操作力不会过大，否则使触发组件可能会被卡止在解锁位置中或使用者将需要非常的大力才能解除触发环1000与输送管座2000的相互止挡作用。另一方面，当需要锁止触发组件以例如使雾化器保持在预触发状态下时，该三维倾斜的第一锁止面1110能够在多个维度上均有效抵靠第二锁止面2110，防止其进一步的竖直向上的移动和/或旋转运动。由此可见，三维倾斜的第一锁止面1110在防止卡止与防止自动雾化之间取得了期望的平衡作用。
在进一步的示例中，图3示出了图2中的局部R的放大示意图。在此可见，在此大致梯形设置的第一锁止面1110在水平平面的投影。在此，第一锁止面1110的投影与触发环1000的第一径向方向X’之间的夹角A’在5°至50°的范围内，优选在5°至30°的范围，例如为约15°，并且该投影与触发环1000的第二径向方向Y’之间的夹角B’在3°至60°的范围内，优选在5°至20°的范围内，例如为约20°。当夹角A’大于夹角B’(例如夹角A’比夹角B’大5°至10°)时是尤其有利的，由此，在解锁组件从锁止位置运动到解锁位置的过程中，锁止凸起部1100与锁止凹口2100之间的相对滑动是平稳且牢固的。同样有利的是，第一锁止面1110在竖直平面上的投影与触发环1000的轴向方向Z’之间的夹角C’在15°至80°的范围内，优选在30°至50°的范围内。
锁止凸起部1100还包括导向面1120，其在此为锁止凸起部1100的底面并且水平设置。当然，导向面1120也可以相对于水平平面稍倾斜地设置。在触发组件的位置转换过程中，该导向面1120可以与锁止凹口2100的凹槽底部相接触，由此使得转换过程更加平稳。
此外，锁止凸起部1100还包括过渡面1130，用于限制触发环1000的旋转运动，使得触发环1000在受其约束的情况下只能进行平移。
下面，参照附图5至附图8详细地描述根据本公开的一种实施方式的输送管座2000。该输送管座2000可包括桶状的管座本体2200以及设置在管座本体上的第二锁止部(在此，例如为在该管座本体2200的一侧内凹设置的锁止凹口2100)。虽然在图中示出有两个锁止凹口2100和2100’，但是应理解的是，锁止凹口2100的数量和布置并非是限制性的，而是根据需要可在管座本体2200的上壁上设置任意数量的锁止凹口2100并且在这些锁止凹口2100的一侧或两侧的壁上可分别设置不同数量的第二锁止面2110。锁止凹口2100的灵活设置可能性使得解锁组件的运动级可根据需要进行适配。
虽然本实施例中，以锁止凸起部1100作为第一锁止部的示例，并且以锁止凹口2100作为第二锁止部的示例，然而还可设想的是，在另一实施例中，第一锁止部构成为锁止凹口的形式，而第二锁止部则构成为锁止凸起部的形式。应理解的是，只要第一锁止部与第二锁止部能够实现互锁及解锁功能，则锁止凸起部与锁止凹口布置是可以互换的或可根据需求进行选择使用的。
锁止凹口2100的至少一个壁构成第二锁止面2110，该第二锁止面2110与上述第一锁止面1110向互配合，即当触发组件位于锁止位置中时，第二锁止面2110与第一锁止面1110相互抵靠。随着触发环1000例如在按压开关的作用下的移动，第一锁止面1110贴靠在第二锁止面2110地在其上滑动，当滑过第二锁止面2110时，则触发组件进入到解锁位置。
与第一锁止面1110相类似的是，该第二锁止面2110也是三维倾斜的斜面，亦即该第二锁止面2110不仅相对于水平平面(XY平面)相倾斜，而且也相对竖直平面(ZY平面和XZ平面)相倾斜。换句话说，该第二锁止面2110既是输送管座2000的径向向内的表面，也是该输送管座2000的轴向向内的表面。
作为一种示例，第二锁止面2110的法向方向F与输送管座2000的第一水平方向X的夹角β在55°至90°的范围内，优选在67°至87°的范围，或优选在60°至90°的范围，尤其优选为77°，第二锁止面2110的法向方向F与输送管座2000的第二水平方向Y的夹角γ在145°至185°的范围内，优选在150°至180°的范围，优选在155°至178°的范围，尤其优选为167°，并且其中，第二锁止面2110的法向方向F与输送管座2000的所述竖直方向Z的夹角α在30°至60°的范围内，优选在40°至55°的范围，尤其优选为46.3°。在本公开中，输送管座2000的“第一水平方向X”、“第二水平方向Y”分别对应于该输送管座2000的径向方向，而输送管座2000的“竖直方向Z”对应于该输送管座2000的轴向方向。这些方向X、Y和Z参见附图5至附图8中的坐标系标记。
在此，第二锁止面2110的这种三维倾斜布置是非常有利的，一方面，当其与设置在第一锁止面1110相配合时，用于将触发组件从锁止位置切换到解锁位置的操作力不会过大，否则使触发组件可能会被卡止在解锁位置中或使用者将需要非常的大力才能解除触发环1000与输送管座2000的相互止挡作用。另一方面，当需要锁止触发组件以例如使雾化器保持在预触发状态下时，该三维倾斜的第二锁止面2110能够在多个维度上均有效抵靠第一锁止面1110，防止其进一步的运动。由此可见，三维倾斜的第二锁止面2110在防止卡止与防止自动雾化之间取得了期望的平衡作用。
在进一步的示例中，图7示出了图6中的局部S的放大示意图。在此可见，在此大致为平行四边形的第二锁止面2110在水平平面的投影。在此，第二锁止面2110在水平平面上的投影与输送管座2000的第一径向方向X之间的夹角A在5°至60°的范围内，优选在10°至45°的范围，例如为30°，并且第二锁止面2110在水平方向上的投影与输送管座2000的第二径向方向Y之间的夹角B在5°至60°的范围内，优选在5°至25°的范围内，例如为15°。当夹角A大于夹角B(例如夹角A比夹角B大5°至10°)时是尤其有利的，由此可控制解锁组件从锁止位置运动到解锁位置的行程。此外，第二锁止面2110在竖直平面上的投影与输送管座2000的轴向方向Z之间的夹角C在15°至80°的范围内，优选在35°至55°的范围内。
锁止凹口2100还包括可以与导向面1120相接触的凹槽底部以及两个侧壁，第二锁止面2110设置在一个壁中。从附图中还可见，作为一种优选的实施例，锁止凹口2100还包括引导斜面2120，该引导斜面2120具有与第二锁止面2110共用的边缘，并且第二锁止面2110的径向尺寸d1与引导斜面2120的径向尺寸之和等于管座本体2200该侧的径向壁厚尺寸d2。引导斜面2120也构成为大致平行四边形的形状并且与第二锁止面2110大致沿圆周方向等角度排列设置在同一位置。在此，该引动斜面2120可例如用于引导解锁组件到解锁位置中，以防在解锁组件突然离开锁止位置的情况下，解锁环由于过于自由的运动而偏离太远。在设置有该引导斜面2120的实施方式中，第二锁止面2110的径向尺寸d1大于输送管座2000该侧的径向壁厚尺寸d2的二分之一，优选大于输送管座2000该侧的径向壁厚尺寸d2的三分之二。引导斜面2120在水平方向上的投影在附图7中示出，该水平投影与输送管座2000的第二径向方向Y之间的夹角等于第二锁止面2110在水平方向上的投影与所述输送管座2000的第二径向方向Y之间的夹角B。优选的是，引导斜面2120在水平平面上的投影与所述输送管座2000的第一径向方向X之间的夹角D在20°至80°的范围内，优选在40°至65°的范围内，例如为45°。优选的是，该引导斜面2120的法向方向与输送管座2000的第一水平方向X的夹角在135°至160°的范围内，该引导斜面2120的法向方向 与输送管座2000的第二水平方向Y的夹角在115°至135°的范围内，并且其中，该引导斜面2120的法向方向与输送管座2000的竖直方向Z的夹角在115°至135°的范围内。
可以理解的是，该引导斜面2120仅作为一种优选的布置结构，而并非是必须的。当不设置引导斜面2120的情况下，第二锁止面2110亦可以占据该壁厚的全部径向尺寸。
输送管座2000还包括与喷雾器的其他构件，例如容器4000、旋转件6000或壳体8000进行例如卡接的连接的接片2500。输送管座2000还包括输送管2400，用于将储存在容器4000中的液体输送到喷雾的喷射腔中。
作为一种优选的实施方式，在输送管座2000的底部还可设置有弹性件，例如弹簧5000。该弹簧5000始终向输送管座2000施加向上的推力，使得一旦触发组件离开锁止位置，则输送管座2000即可向上进行运动，即进行轴向运动。当输送管座2000的外径小于或等于触发环1000的内径时，该输送管座2000可在弹簧5000的作用下向上穿过触发环1000的，并且在向输送管座2000施加向下的力时，输送管座2000又可克服弹性力向下运动并回到锁止位置。应理解的是，该弹簧5000是雾化器的优选部件，而非必须的。还可设想其他的替代部件，例如按钮，只要这些部件也能为输送管座2000提供轴向向上的推力即可。
输送管座2000内部还可设置有螺旋部2600，其设置在从管座本体2200的内壁上径向向内的突出部的上表面。当输送管座2000布置到雾化器中时，该螺旋部2600可例如与吸嘴7000的对应的螺旋部7100相配合。由此，当将输送管座2000进行旋转时，该输送管座2000可在竖直方向，即轴向方向上进行运动。在本公开中，在输送管座2000向下运动的过程中，该输送管座2000在螺旋部的作用下进行带有旋转的向下运动，亦即进行同时旋转和向下平移的复合运动，而在该输送管座2000向上运动的过程中，该输送管座2000可进行单纯的向上平移运动，而不进行任何旋转。
在本公开中，触发组件可例如由上述触发环1000和上述输送管座2000构成，并且为了实现防止雾化器的自动触发，该触发组件可在锁止位置与解锁位置之间运动。下面，参照附图9至附图11详细地描述根据本公开的一种实施方式的触发组件的一种锁止位置，并且参照附图12至附图16详细地描述根据本公开的一种实施方式的触发组件的两种解锁位置，其中，附图12至附图14示出触发组件的第一解锁位置，而附图15至附图16示出触发组件的第二解锁位置。
在附图9至附图11中示出处于锁止位置中的触发组件。在此，该锁止位置例如对应于雾化器的预触发位置，即当雾化器的壳体8000被旋转使得输送管座2000沿着螺旋面对向下运动(优选带有旋转的向下运动)到锁止凸起部1100与锁止凹口2100相互止挡的位 置。在该预触发位置中，雾化器是稳定的，即被防止意外的触发，因为锁止凸起部1100与锁止凹口2100相互止挡使得它们之间的任何一个部件都不能在没有人为操作的情况下进行运动。
在该锁止位置中，锁止凸起部1100的第一锁止面1110抵靠在锁止凹口2100的第二锁止面2110上，以实现所述触发环1000与所述输送管座2000相互止挡。如上所述，由于不仅第一锁止面1110、而且第二锁止面2110均是三维斜面，这相互止挡是非常可靠的，且能够保证不会由于意外操作(例如雾化器的受撞击或意外滑落)而解锁。
作为一种有利的实施方式，在该锁止位置中，所述触发环1000相对于输送管座2000非同轴线地设置、即它们之间是偏心设置的。
为了使该触发组件转换至解锁位置，向触发环1000施加水平推力即可。该水平推力可以是由于按压开关被人为按压而间接施加到触发环1000上的，也可以是人为直接施加到触发环1000上的。
应理解的是，只要触发组件离开锁止位置，则其便进入到解锁位置。换句话说，只要雾化器不需要被锁止以防意外触发，触发组件即可到达解锁位置中，以便于雾化器的自由操作。
在附图12至附图14和附图15至附图16中分别示出处于第一解锁位置和第二解锁位置中的触发组件。在此，“第一解锁位置”和“第二解锁位置”仅为了清楚说明而做出区分，而并不代表它们之间的顺位关系。
在附图12至附图14所示的第一解锁位置既可以是一个过渡状态，也可以是一种稳定状态，因为当第一锁止面1110不再与第二锁止面2110接触时，输送管座2000可相对于触发环1000在轴向方向上运动。并且如上所述，由于触发环1000被水平推动以使得触发组件离开锁止位置，因此，在第一解锁位置中，触发环1000相对于所述输送管座2000同轴线地设置，即它们之间不再偏心。此时，如果输送管座2000的外径小于或等于触发环1000的内径，则输送管座2000即可穿过触发环1000以到达第二解锁位置。
为了促使输送管座2000穿过触发环1000，可在输送管座2000的下方设置推力机构，例如弹簧5000。在设置有弹簧5000的情况下，该第一解锁位置是一个过渡的状态，因为一旦触发环1000被水平推动使得第一锁止面1110滑过第二锁止面2110，则输送管座2000即会在弹簧5000的作用下向上运动。在不设置弹簧的情况下，该第一解锁位置是一个相对稳定的状态，因为即使触发环1000被水平推动使得第一锁止面1110滑过第二锁止面2110，输送管座2000也不会立刻受力向上运动。在这种情况下可以考虑按钮等其他被动的操作结构。
无论是由于弹簧的主动加压还是按钮等其他替代结构的被动推动，在输送管座2000穿过触发环1000之后，触发组件即可到达附图15至附图16中示出的第二解锁位置。可以理解是，在触发组件从第一锁止位置转换到第二锁止位置的过程中，输送管座2000可进行单纯的竖直向上运动，即不带有旋转的向上移动，从而相对于触发环1000到达第二解锁位置。
附图15中示出的第二解锁位置可以对应于雾化器的初始转态，即雾化器未被进行任何操作的状态。从该初始状态出发，当输送管座2000随着壳体8000和旋转件6000进行旋转时，输送管座2000在螺旋面2600的作用下相对于触发环1000向下枢转，直至第一锁止面1110贴靠至所述第二锁止面2110，则到达附图9中示出的锁止位置，即雾化器的预触发状态。此时，向触发环1000施加基本水平的推力，即可使触发组件离开锁止位置以到达图12所示出的第一解锁位置，由此完成一个行程周期。
可以理解的是，触发组件的行程周期可以对应于触发环1000和输送管座2000的一整圈旋转或部分旋转，这取决于在触发环1000和和输送管座2000上所设置的锁止凸起部1100和锁止凹口2100的相应数量和布置位置。
最后，参照附图17至附图19来说明根据本公开一种示例的雾化器。为了控制或者说防止雾化器的触发，雾化器包括上述触发组件。在此，触发环1000构成为所述雾化器的开关按钮，或者触发环1000与雾化器的开关按钮连接，使得触发环1000能够随着开关按钮被按压而运动。输送管座2000构成为雾化器的壳体，或者输送管座2000与雾化器的壳体连接，使得输送管座2000能够随着壳体的旋转而旋转亦或螺旋地运动。
当雾化器处于初始位置时，触发组件位于解锁位置中，而当雾化器处于预触发位置时，触发组件位于锁止位置中。为此，输送管座2000能够在解锁位置中旋转，以使雾化器从初始位置运动至预触发位置，并且触发环1000能够在锁止位置中被按压以进行移动，例如大致水平运动，以使雾化器从预触发位置运动回初始位置。
除了触发组件之外，雾化器还可包括其他构件，例如，壳体8000、按压开关3000、用于容装待雾化的液体的容器4000、向输送管座2000施加推力的弹簧5000、套设在输送管座2000上的旋转件6000、(在使用过程中可被放置于使用者口部的)吸嘴7000、用于雾化并喷射出雾化液体的喷射组件9000、防尘盖11000等。
在如附图17至附图19所示的配置下，雾化器可以、但不必然具有如下操作方式。
首先，当雾化器处于初始位置中时(此时，触发组件位于如附图15和16所示的第二解锁位置)，使用者握住壳体8000并将壳体旋转一定的角度，旋转件6000带着输送管座2000一起随着壳体8000的旋转而(例如螺旋地)向下移动，直至触发组件运动到如附图9 至附图11所示的锁止位置。
此时，雾化器处于预触发位置，第一锁止面1110贴靠至第二锁止面2110上，使得触发环1000与输送管座2000相互止挡，两者都不能再无外力的情况下进一步运动。在该锁止位置中，如果使用者不刻意施加外力，则雾化器不会进行雾化或喷射操作，即使该雾化器受到外力冲击，例如撞击或晃动，甚至是从高处滑落等意外情况。因此，雾化器在该状态下被有效地锁止。
当使用者要使用雾化器时，可对按压开关3000施加径向向内的推力。由于第一锁止面1110和第二锁止面2110分别三维倾斜的结构，该推力被控制在合理的范围内。否则，为了保证锁止效果，使用者将必须在解锁时施加较大的操作力，这无疑将造成使用感受的下降并且降低用户友好性。此时，触发环1000随着按压开关3000的移动也进行移动。可以理解的是，由于第一锁止面1110在第二锁止面2110进行三维方向地滑动，触发环1000的这种随着按压开关3000的移动并非仅仅是直线平移，而是可以做带有旋转的曲线平移。这种曲线平移使得触发组件在锁止位置与解锁位置之间进行相对平稳的转化。优选的是，在该滑动过程中，触发环1000的导向面1120也与锁止凹口2100的凹槽底部相接触并相对滑动，这种双重的接触滑动可减少第一锁止面1110与第二锁止面2110之间的摩擦，并从而延长触发组件的使用寿命。
一旦触发环1000的第一锁止面1110相对于第二锁止面2110运动到不再接触的位置，则雾化器将从预触发位置进入自由位置(此时触发组件将位于如图12至14所示的第一解锁位置)。在该自由位置中，雾化器不被锁定，因此输送管座2000是相对于触发环1000可自由运动的。然而，由于在该雾化器中，输送管座2000在径向方向上受到旋转件6000或壳体8000的约束，所以该输送管座2000只能在轴向方向上相对于触发环1000运动。又由于输送管座2000的外径小于触发环1000，因此该输送管座2000可以被动地或主动地，例如通过弹簧力或推力地穿过触发环1000向上竖直运动到最高点，从而触发组件又例如回到了如附图15和16所示的第二解锁位置，亦即，雾化器有恢复到了初始位置中。
应理解的是，附图中所示出的雾化器的内部结构和部件是示例性的，而非限制性的结构。在此，只要能够实现雾化器的防止误操作或防止意外触发的功能即可，因此，包括上述能够实现该功能的触发组件的雾化器可具有任何结构和部件，而不限于上述附图中的部件和布置。此外，雾化器的上述操作方式也同样是示例性的，而非限制性的。当雾化器中的部件被省略或替换是，其操作方式也可进行相应的变换以满足使用需求。
以上所述仅为本公开的实施例或示例，并非因此限制本公开的专利范围，凡是在本公开的构思下，利用本公开说明书及附图内容所作的等效结构变换，或直接/间接运用在 其他相关的技术领域均包括在本公开的专利保护范围内。实施例或示例中的各种要素可以被省略或者可由其等同要素替代。此外，可以通过不同于本公开中描述的次序来执行各步骤。进一步地，可以以各种方式组合实施例或示例中的各种要素。重要的是随着技术的演进，在此描述的很多要素可以由本公开之后出现的等同要素进行替换。
