Description

双鸭嘴阀组件
技术领域
本发明总体上涉及鸭嘴阀领域，更具体而言，涉及一种新的鸭嘴阀布置。
背景技术
鸭嘴阀已被普遍熟知。鸭嘴阀前端(上端)具有缝隙，在正压差下，该缝隙开启以允许流体从其中流出。反之，在负压差下，该缝隙关闭以阻止回流。不同形状和大小的鸭嘴阀用于特定的运用。例如，其可用在导流式牙刷中。
然而已经知道，牙刷中的现有可用鸭嘴阀可从刷毛板上掉落下来，或能被轻易从其所在的刷毛板上拉出来。此外，目前尚没有典型的利用自动化制造设备能便捷可靠地将鸭嘴阀定位在刷毛板上的方法。因此，鸭嘴阀的缝隙在刷毛板上的位向可变。
另外，常规的鸭嘴阀可被堵塞，或由于存在鸭嘴阀构造的限制，流出的流体未能覆盖期望的区域。此外，特别对于牙刷，可能需要导流一股以上的流体，这将导致鸭嘴阀的流体路径复杂化。
人们期待着能克服上述一种或一种以上缺陷的鸭嘴阀的问世。
发明内容
因此，本发明是一种鸭嘴阀组件，包括：
至少两个鸭嘴阀构件；及凸缘构件，在该鸭嘴阀构件之间延伸并以特定位向连接该鸭嘴阀构件。
附图说明
图1是本发明鸭嘴阀应用于牙刷的刷柄/刷头部分的分解图。
图2是图1所示鸭嘴阀的立体图。
图3是带有图1和图2所示鸭嘴阀的牙刷刷柄/刷头的正视图。
图4是带有图1和图2所示鸭嘴阀的牙刷刷头的剖面图。
具体实施方式
现参阅图2，本发明双鸭嘴阀组件，总体上用附图标记10来标示，包括两个鸭嘴阀构件12，14，该两个鸭嘴阀构件12，14在其各自的基部通过凸缘16相连。鸭嘴阀构件12，14类似于常规鸭嘴阀，其包括圆形下部18及带有矩形上表面21的锥形上部20。每个鸭嘴阀构件12，14均系中空结构，并且带有用以容纳流体的开口基部(下端)及位于上表面21上的缝隙22，该缝隙22延伸过该上表面21的大部分长度以使流体从阀中流出，鸭嘴阀构件12，14系用诸如橡胶等柔性材料制成。
在正压差下，缝隙22开启以允许流体自由流过该阀。在负压差下，缝隙22保持紧闭以阻止回流过阀体。另外，鸭嘴阀的基本结构已熟知；因应用不同，制造时对鸭嘴阀的尺寸及构造的广泛改变都是可接受的。
在申请者的发明中，凸缘16连接着双鸭嘴阀构件的基部，由此形成整体物件并且维持该分离的阀构件的固定空间关系。
在该实施例中，凸缘构件16也系柔性材料制成，其厚度约为0.5mm。凸缘构件16可具有各种构造，如图2所示，其包括两个笔直的平行纵向侧面28，30，带有弯曲端部32，34连接着该纵向侧面，且略为超出鸭嘴阀构件的边缘以便于制造。在该实施例中，凸缘构件16长为13.8mm，宽约为4.2mm，两个鸭嘴构件彼此分离，其中心线距离为10.5mm，上述尺寸可因不同应用改变。
图1表示双鸭嘴阀组件10应用于牙刷的分解图。图3和图4表示装配组合图。鸭嘴阀组件10插入到位于刷毛板44上的腔体42中。刷毛板的保持厚部48中设有相间的孔，两个单独的鸭嘴阀构件12，14从该孔中伸出以致延伸到安装于刷毛板44上的刷毛50的区域。安置构件55遂设在位于腔体42中的鸭嘴阀组件10的上面，以将该组件安置在腔体42中适当位置且抵靠在刷毛板的保持厚部48上。该插入的安置构件设置成：在刷毛板中界定了容纳从罐流经刷柄部分58的流体的腔体57或通道。鸭嘴构件的开口基部通过位于凸缘16上的孔52，54与位于刷毛板中的腔体流体地相连通。此布置允许当处于正压差下，流体流到单独的鸭嘴阀构件12，14，并从其具有缝隙的上端流出，达到刷毛区域50。
尽管该所示布置包括的两个单独鸭嘴阀构件的位向定成：其缝隙22-22互相平行横向地穿过凸缘16，但是，该两个鸭嘴阀构件的位向也可定成：使得缝隙在沿着牙刷的单一线路内(在单一直立平面内)。
此外，应该理解，在具体的组件中，鸭嘴阀构件的数量也可以多于两个。再者，单独的鸭嘴阀构件可分别具有彼此不同的大小和/或形状以收容两股不同的流体。但是，如果该两个鸭嘴阀构件连通于相同的流体路径，有益地，其大小、形状及位向就设置成彼此相同。另外，在牙刷中应用时，如图1所详示，有益地，鸭嘴阀构件彼此相分离开距离，以收容位于其之间的刷毛区的刷毛。
本发明多个鸭嘴阀的组件具有以下优点。第一，当鸭嘴阀组件只能以一个位向装配在刷毛板上时，准许具有适宜鸭嘴位向的简易自动装配。此外，因为凸缘16与刷毛板的保持厚部48的内表面相接触，所以很难从刷毛板上将鸭嘴拉出；再者，如上所指，本鸭嘴组件结构能收容两个分离的流体路径，该路径用于两股不同的流体通过牙刷刷柄。因此，本发明多个鸭嘴阀的组件不仅克服了单一鸭嘴组件的缺点，还具有附加的优点。
尽管作为示例，已经揭示了本发明的优选实施例，应该理解，在不偏离本发明的、由下述权利要求书所界定的精神下，可以对实施例作出各种变更，修改及替代。
