Description

雾化器 技术领域
本发明涉及一种雾化器，尤其涉及一种可检测压力变化的雾化器。
背景技术
首先，现有技术的雾化器经启动后便持续地以相同速率喷化出药液气雾，没有自动配合患者的呼吸频率变化、速率变化、波形变化、肺活量大小做雾化量的调整，也就是没有全面考虑个体差异对药剂吸入量的影响。也就是说，在患者未进行吸气的时间雾化器仍会持续地以相同速率喷出药液气雾，导致药物利用率的下降且或使用者不适。为解决前述问题，现有雾化器采用压力检测器，用以检测病患使用雾化器时的呼吸压力变化，作为雾化器被驱动产生药物气雾的信息依据，然而压力检测器通常是安置在雾化器内部，因此雾化器的结构会导致雾化后的气体影响压力检测器的准确度下降。
故，如何通过雾化器的结构设计改良，以避免雾化后的气体进入压力检测通道而影响检测器对呼吸压力检测的灵敏度与准确度，来克服上述的缺陷，已成为该项事业所欲解决的重要课题之一。
发明内容
本发明所要解决的技术问题在于，针对现有技术的不足提供一种雾化器，其包括主机、接合件、杯体、咬嘴及感测组件。主机具有头部。杯体底部具有雾化模块。接合件包括相互连通的第一接口、第二接口以及第三接口。杯体通过第一接口耦接于接合件。接合件通过第三接口接合于头部而耦接于主机。接合件内部具有第一分隔壁。咬嘴具有相对设置的第一开口与第二开口。咬嘴通过第二开口接合于第二接口而耦接于接合件。咬嘴包括舌板，舌板设置在咬嘴内部并且抵靠于第一分隔壁。舌板将咬嘴内部分隔为第一通道与第二通道。感测组件设置在主机内部，感测组件与第一开口之间的水平距离小于雾化模块与第一开口之间的水平距离。
优选地，雾化器进一步包括一第二分隔壁，第二分隔壁可拆卸地设置在杯体底部，第二分隔壁与第一分隔壁将接合件内部分隔出一腔体，第一通道与腔体相连通，头部具有一 通孔，第二通道通过第二接口及通孔与主机内部相连通。
优选地，第二分隔壁可拆卸地设置在接合件内部。
优选地，接合件的两侧分别设置一第一扣接件，主机两侧分别设置一对应第一扣接件的第二扣接件，其中，当接合件耦接于主机时，第一扣接件扣接于第二扣接件。
优选地，通孔连通主机内部与第二通道，感测组件通过通孔连通第二通道，以感测第二通道的压力变化。
优选地，雾化器进一步包括一防水组件，防水组件套设在通孔。
优选地，通孔是开设在头部的上表面。
优选地，通孔是开设在头部的侧表面。
优选地，感测组件电性连接雾化模块，主机进一步包括一控制单元，当用户对第一开口吸气时，感测组件通过检测第二通道的压力变化而输出一第一感测信号至控制单元，控制单元依据第一感测信号而输出一第一控制信号至雾化模块。
优选地，当使用者对第一开口呼气时，感测组件通过检测第二通道的压力变化而输出一第二感测信号至控制单元，控制单元依据第二感测信号而输出一第二控制信号至雾化模块。

优选地，低平台表面为凹陷表面。
优选地，第一分隔壁包括一沉槽。
优选地，接合件在第二接口与第三接口之间的侧壁与头部的侧表面之间形成一凹槽。
本发明的其中一个有益效果在于，本发明所提供的雾化器，其能通过“舌板将咬嘴内部分隔为第一通道与第二通道，并分别连通腔体及通孔”以及“感测组件与第一开口之间的距离小于雾化模块与第一开口之间的距离”的技术方案，以避免雾化后的气体进入压力检测通道而影响对呼吸压力检测准确度，并提高压力检测的灵敏度。

具体实施方式
以下是通过特定的具体实施例来说明本发明所公开有关“雾化器”的实施方式，本领域技术人员可由本说明书所公开的内容了解本发明的优点与效果。本发明可通过其他不同的具体实施例加以施行或应用，本说明书中的各项细节也可基于不同观点与应用，在不悖离本发明的构思下进行各种修改与变更。另外，本发明的附图仅为简单示意说明，并非依实际尺寸的描绘，事先声明。以下的实施方式将进一步详细说明本发明的相关技术内容，但所公开的内容并非用以限制本发明的保护范围。
应当可以理解的是，虽然本文中可能会使用到“第一”、“第二”、“第三”等术语来描述各种元件，但这些元件不应受这些术语的限制。这些术语主要是用以区分一元件与另一元件。另外，本文中所使用的术语“或”，应视实际情况可能包括相关联的列出项目中的任一个或者多个的组合。
第一实施例
参阅图1与图2所示。本发明提供一种雾化器M，由雾化器M的外观结构来看，其主要结构包括主机1、接合件2、咬嘴3以及杯体6。咬嘴3进一步包括第一定位部35，所述接合件2在靠近第二接口212的地方设有对应第一定位部35的第二定位部25，咬嘴 3通过第一定位部35扣接于第二定位部25而接合于接合件2。
参阅图3与图4所示，分别表示雾化器的分解示意图。主机1、接合件2及咬嘴3是能够拆解以及组装的组件，也就是说，主机1与接合件2为相互接合而成的组合件，接合件2与咬嘴3为相互接合而成的组合件。然而，上述所举的例子只是其中一可行的实施例而并非用以限定本发明。举例来说，在另一实施例中，接合件2与咬嘴3也可以是一体成型的组件。进一步来说，主机1具有头部11。头部11具有一通孔111，通孔111是开设在头部11的上表面。更具体来说，主机1的头部11基本上为一阶梯形状的凸出结构，其包括一高平台表面113与一低平台表面114，低平台表面114设置在通孔111与高平台表面113之间。
继续参阅图4所示，接合件2的两侧分别设置第一扣接件22。主机1两侧分别设置一对应第一扣接件22的第二扣接件12。当接合件2耦接于主机1时，第一扣接件22扣接于第二扣接件12。在本发明中，第一扣接件22为一扣孔，而第二扣接件12为一卡勾。然而，本发明并不以此为限。
参阅图5所示，图5为本发明第一实施例的雾化器的接合件的示意图。接合件2包括相互连通的第一接口211、第二接口212以及第三接口213，且接合件2的内部具有第一分隔壁201。第二接口212与第三接口213之间具有一侧壁26。雾化器M进一步包括第二分隔壁202，第二分隔壁202与接合件2为一体成型。第二分隔壁202与第一分隔壁201将接合件2的内部分隔出一腔体203。第二分隔壁202具有第二贯孔204，第一接口211通过第二贯孔204与腔体203相连通，而第二接口212也与腔体203相连通。
图6为本发明第一实施例的雾化器的杯体与接合件的组合剖视示意图，杯体6与接合件2的组装可一并参阅图4所示。当杯体6与接合件2相组装时，杯体6是设置在第一接口211，且此时第一贯孔61与第二贯孔204相对设置。进一步来说，第一分隔壁201为一阶梯形状，第一分隔壁201相对于腔体203侧具有一容置部2011，容置部2011的形状与高平台表面113相互对应。
图7为本发明第一实施例的雾化器的剖视示意图，接合件2与主机1的组装可一并参阅图4所示。接合件2通过第三接口213接合于头部11而耦接于主机1，其中高平台表面113位在容置部2011中。咬嘴3具有相对设置的第一开口31与第二开口32。咬嘴3通过第二开口32接合于第二接口212而耦接于接合件2。如图7所示，本发明的雾化器M进一步包括雾化模块4与感测组件5，雾化模块4设置在第二贯孔204上方，感测组件 5设置在主机1内部。杯体6底部具有第一贯孔61，且第一贯孔61位于雾化模块4上方。换言之，雾化模块4是设置在第一贯孔61与第二贯孔204之间。
杯体6内部能够置放药液，药液通过第一贯孔61，由雾化模块4将药液转化为气雾，接着气雾再通过第二贯孔204散布在腔体203。值得一提的是，雾化模块4的水平摆放方式，能够使其产生的气雾散布在腔体203而不是直接喷向第一开口31。此外，当接合件2耦接于主机1时，接合件2的侧壁26与头部11的侧表面112之间会形成一凹槽27。此外，本发明的雾化器M还进一步包括一密封圈8，密封圈8是环绕主机1的头部11设置。当接合件2耦接于主机1时，密封圈8位在接合件2与主机1的接合处。
再次参阅图7所示，咬嘴3包括舌板30，舌板30设置在咬嘴3内部并且抵靠于第一分隔壁201。舌板30将咬嘴3内部分隔为各自独立的第一通道33与第二通道34。其中，第一通道33与腔体203相连通，第二通道34通过第二接口212及通孔111与主机1内部相连通。通孔111连通主机1内部与第二通道34，因此设置在主机1内部的感测组件5能够感测第二通道34的压力变化。进一步来说，感测组件5与第一开口31之间的水平距离H1小于雾化模块4与第一开口31之间的水平距离H2，更具体来说，水平距离H1为感测组件5与咬嘴3用以形成第一开口31的端缘之间的距离，水平距离H2为雾化模块4与咬嘴3用以形成第一开口31的端缘之间的距离。此外，雾化器M还进一步包括一防水组件7，防水组件7套设在通孔111，并且完全遮盖感测组件5的感测区，其中，感测组件5依据通孔111的方位呈垂直方向设置于主机1内部。防水组件7能够阻隔水气，避免水气从通孔111进到主机1内部，影响主机1内部的电路及电子组件的功能性。
值得一提的是，虽然在本实施例中的第二分隔壁202与接合件2为一体成型，然而，本发明不限于此。在其他实施例中，参阅图8所示，第二分隔壁202也可以是独立的组件，并可拆卸地设置在杯体6底部，也可拆卸地设置在接合件2内部。
另外，雾化器M的主机1的头部11可以有不同的实施方式。请参阅图9与图10所示，头部11介于高平台表面113及通孔111之间的低平台表面114可为一凹陷表面，而接合件2的第一分隔壁201可形成一沉槽，沉槽的结构设计能够拉长第一分隔壁201与雾化模块4之间的距离，也就是让腔体203的空间变大。当雾化模块4将药液转化为气雾，而气雾通过第二贯孔204散布在腔体203时，由于第一分隔壁201与雾化模块4之间的距离拉长，延长了气雾碰触到第一分隔壁201而凝结成水珠的时间，让使用者能够吸入较多的气雾。
第二实施例
参阅图11及图12所示，第二实施例中的雾化器M与第一实施例中的雾化器M在结构及功能上大部分相同或相似，其相同或相似的结构及功能在此不再加以赘述。本发明第二实施例的雾化器M与第一实施例相比，最大的不同在于主机1的通孔111的出口方向有所相异。详细来说，本实施例中的通孔111是开设在头部11的侧表面112，其出口方向是往前朝向第一开口31。而在第一实施例中(见图4)，通孔111是开设在头部11的上表面，其出口方向是往上朝向第一分隔壁201。
同样地，在本实施例的雾化器M还包括一防水组件7，防水组件7套设在通孔111，并露出部分通孔111及感测组件5的感测区，其功能与第一实施例相同，是用来阻隔水气。值得一提的是，第二实施例中的雾化器M所示出的感测组件5本身即具有一定程度的防水功能，因此在防水组件7可露出感测组件5的感测区，其中，感测组件5依据通孔111的方位呈水平方向设置于主机1内部。因此，相较于第一实施例，第二实施例中的感测组件5更能明显的感测到第二通道34的压力变化，意即第二实施例中的感测组件5具有较佳的灵敏度。然而，上述所举的例子只是其中一可行的实施例而并非用以限定本发明。本发明的雾化器M并不受限于感测组件5与防水组件7的机构设计。
接着，请参阅图13与图14所示，图13为本发明第二实施例的雾化器在吸气时动作示意图，图14为本发明第二实施例的雾化器在呼气时动作示意图。需说明的是，有关本发明的雾化器M的动作方式虽是以本实施例(第二实施例)示出的雾化器M结构来做为示例说明，然而，上述所举的例子只是其中一可行的实施例而并非用以限定本发明。事实上，本发明的雾化器M的动作方式同样适用于第一实施例所示的雾化器M结构，合先叙明。
如图13所示，感测组件5电性连接雾化模块4，且主机1进一步包括一控制单元13。当使用者对第一开口31吸气时(第一开口31处的箭头指示方向为吸气方向)，感测组件5通过检测第二通道34的压力变化而输出一第一感测信号S1至控制单元13。控制单元13依据第一感测信号S1而输出第一控制信号C1至雾化模块4。雾化模块4依据第一控制信号C1而启动将药液转化为气雾，并且气雾通过第二贯孔204散布在腔体203。接着，气雾通过第一通道33与第一开口31被使用者吸入体内。
如图14所示，当使用者对第一开口31呼气时，感测组件5通过检测第二通道34的压力变化而输出第二感测信号S2至控制单元13。控制单元13依据第二感测信号S2而输出第二控制信号C2至雾化模块4。雾化模块4依据第二控制信号C2而停止将药液转化为 气雾。
实施例的有益效果
本发明的其中一个有益效果在于，本发明所提供的雾化器M，其能通过“舌板30将咬嘴3内部分隔为第一通道33与第二通道34，并分别连通腔体203及通孔111”以及“感测组件5与第一开口31之间的距离小于雾化模块4与第一开口31之间的距离”的技术方案，以避免雾化后的气体进入压力检测通道而影响对呼吸压力检测准确度，并提高压力检测的灵敏度。
进一步来说，如图13与图14所示，当使用者对着第一开口31吸气或呼气，会在第二通道34间凝结成水气。通过凹槽27的结构设计，能让所凝结的水气自然积聚于其中，避免凝结水气流入通孔111。
更进一步来说，感测组件5与第一开口31之间的水平距离H1小于雾化模块4与第一开口31之间的水平距离H2，这表示感测组件5相较于雾化模块4更接近第一开口31，也就是更靠近使用者的口腔。当感测组件5设置越接近第一开口31，感测组件5能够感测到较明显的压力变化，意即增加感测组件5的灵敏度。
更进一步来说，在本发明的雾化器M的结构设计中，当咬嘴3接合于接合件2时，舌板30与第一分隔壁201能准确的接合在一起。舌板30将咬嘴3内部分隔为独立分开的第一通道33与第二通道34。其中，第一通道33与腔体203相连通，第二通道34通过通孔111与主机1内部相连通。通孔111连通主机1内部与第二通道34，进一步来说感测组件5是设置在通孔111中，因此设置在主机1内部的感测组件5能够感测第二通道34的压力变化。也就是说，第一通道33与腔体203形成一气雾通道，第二通道34与通孔111形成一压力检测通道。气雾通道与压力检测通道是独立分开，避免药液形成的气雾进入压力检测通道，使气雾的气流干扰到感测组件5对于用户对第一开口31吸气及呼气时的压力检测判断。
以上所公开的内容仅为本发明的优选可行实施例，并非因此局限本发明的权利要求书的保护范围，所以凡是运用本发明说明书及附图内容所做的等效技术变化，均包含于本发明的权利要求书的保护范围内。
