Description

泡沫分配器
技术领域
本发明涉及一种泡沫分配器，所述泡沫分配器包括具有加压推进气体的分配容器、具有下游发泡室的预混合阀、和用于致动所述预混合阀的按钮。
用于从容器中分配例如剃须泡沫或头发摩丝等的泡沫的泡沫分配器用于日常生活中。
背景技术
已知使用一种具有螺纹连接在泡沫分配器的容器上的汲取管的泡沫泵。另一方面，气雾容器与包括具有用于产生泡沫的网的发泡室的发泡构件一起使用。虽然仍在使用具有气雾剂的喷雾和发泡分配器，但是由于环境原因仅能使用基于加压空气的泡沫泵。因为泡沫泵产生的空气的压力取决于抽吸动作，所以对于每一个抽吸动作泡沫的质量可能不同。
发明内容
本发明的目标是提供一种产生恒定质量的泡沫的泡沫分配器。
该目标通过以下所述的泡沫分配器实现，所述泡沫分配器包括具有加压推进气体的分配容器、具有下游发泡室的预混合阀、和用于致动所述预混合阀的按钮。用于维持恒定的预定过压力的压力控制装置设置在分配容器中，所述压力控制装置包括：第一缸筒，所述第一缸筒具有敞开端和封闭端；压力调节活塞，所述压力调节活塞能够在所述第一缸筒内移动从而限定填充有施加所述预定过压力的气体的第一室；第二缸筒，所述第二缸筒限定第二室；通道，所述通道从所述第二室至所述压力控制装置的外侧通向所述容器；和压力调节阀，所述压力调节阀用于打开和关闭所述通道，其中所述第二室填充有压力高于所述预定过压力的气体，并且所述压力调节活塞具有一装置，所述装置用于根据所述第一室和所述容器之间的压力差致动所述压力调节阀以使得当所述容器中的流体压力下降至所述预定过压力之下时，气体从所述第二室流至所述容器，直至所述容器压力近似等于所述预定压力。
在本发明的优选实施例中，阀包括阀杆和具有用于加压气体进入的孔口的预混合室，并且汲取管连接至阀。
在本发明的另一优选实施例中，所述发泡室包括用于产生泡沫的两个相邻的网和用于安装在所述阀杆上的入口。
在本发明的另一优选实施例中，所述发泡室的入口具有比所述阀杆的直径小的直径。
在本发明的另一优选实施例中，具有孔的活塞设置在所述容器内，其中汲取管通过所述孔穿过所述活塞。
在本发明的另一优选实施例中，所述孔通过密封O形圈或通过密封唇相对于所述汲取管被密封。
在本发明的另一优选实施例中，所述活塞为穹顶形。
优选地，所述活塞具有外密封环，该外密封环具有上密封唇和下密封唇。
附图说明
现在，将通过示例参照附图更详细地描述本发明，在附图中：
图1示出具有容器和压力控制装置的泡沫分配器；
图2示出泡沫分配器的第二实施例；和
图3至5示出处于不同位置的第二实施例以解释其工作过程。
具体实施方式
在附图中，如果没有其它说明，相同的附图标记指代相同的元件。
在图1中，泡沫分配器1被描述为具有在WO 2005/082744A中全面描述的压力控制装置3和塑料容器2，该压力控制装置3具有杯状的第一缸筒30、能够以往复运动方式在第一缸筒30内移动的活塞31，以使得第一室32限定在活塞31和第一缸筒30之间。此外，设置高压容器或第二缸筒33，所述高压容器或第二缸筒33在其顶部包围第一缸筒30并且限定第二室34。通道35从第二室34通向压力控制装置3的外侧进入容器2中。阀36打开和关闭通道35。第一室32填充有施加预定的过压力的气体，并且第二室34填充有压力高于预定的过压力的气体。活塞31具有用于根据第一室32和容器2之间的压力差致动阀36的装置，以使得如果容器2中的流体压力下降至预定的过压力之下，则流体从第二室34流至容器2，直至容器压力近似等于预定的压力。在实践中，气体为标准大气。
容器2被具有所谓的尼克尔森(Nicholson)塞5的底部4封闭，该尼克尔森塞5被设置用于给压力控制装置3加压。在容器3的顶部上，安装有具有阀7的封盖6。阀7具有预混合室8，该预混合室8具有用于加压气体或空气的进入的孔口9。阀7连接至柔性汲取管10，该柔性汲取管10在容器2的内部中延伸并且几乎终止于压力控制装置3的顶部上。阀7还具有阀杆11，发泡室12以密封配合方式安装在该阀杆11上。发泡室12具有围绕阀杆11的入口13。在入口13的上游设置有具有小孔15的基部14。在发泡室12中，设置两个相邻的网18和19，其产生均匀紧密且细腻的泡沫。在网18和19的上游，设置具有帽21的出口20，用于挤压阀7并且由此分配泡沫。
填充在压力控制装置3中的空气的压力为大约8巴。由压力控制装置3保持在恒定水平的容器2中的空气的预定过压力为大约0.5巴(bar)。紧挨在压力控制装置3上方，容器2填充有流体25，直至预定的高度26。加压空气27位于流体25上方，该加压流体用于推动流体25通过阀7并且同时被迫通过孔口9进入到预混合室8中。
因为流体25和空气27在恒定压力下混合，所以泡沫非常均匀地产生。此外，两个细网18和19提供了非常紧密且细腻的泡沫。
如上所述的泡沫分配器1必须在大致直立的位置使用。新填充的泡沫分配器1也可以保持稍微倾斜。然而，如果泡沫分配器1是空的，那么加压空气可能会流进汲取管10中，从而使得泡沫的一致性改变并且变稀。另一方面，如果完全填充的泡沫分配器1被保持为几乎水平，那么加压空气也可能会流进汲取管10中，从而使得泡沫变稀。
在图2中，示出了泡沫分配器的另一个实施例50，其中相同的特征具有与图1中相同的附图标记。但是没有示出预混合室8也具有如图1中所示的孔口9。泡沫分配器50具有刚性汲取管51，该汲取管51在离压力控制装置3的上端一较短距离处终止。具有中心孔53和密封O形圈54的穹顶形活塞52围绕汲取管51。朝向容器2的内壁55，穹顶形活塞52具有外密封环56，该外密封环56具有上密封唇57和下密封唇58。柔性密封唇也可以代替O形圈54设置在中心孔53的边界处。
进一步地，泡沫分配器50的工作过程详细示出在图3至5中。在图3中，稍稍向下推动帽或按钮21，以使得阀7稍微打开并且气体或空气将缓慢流过汲取管51。在图4中，按钮21被进一步向下推动，以使得阀7完全打开并且空气27流过汲取管51并且同时穹顶形活塞52被空气27的过压力在活塞52的下侧向上推动，从而还使得活塞52上方的流体25流进预混合室8中，并且泡沫在发泡室12中产生并且被推动通过出口20。当按钮21被释放时，阀7关闭并且泡沫将不再流动。因为活塞52上方流体25的压力不足，所以它被向上推动直至在活塞52的下方和上方之间再次达到压力平衡。图5示出了泡沫分配器50的新的平衡状态。
泡沫分配器的第二实施50具有如下优点：泡沫可以不管该泡沫分配器的位置而被分配，即，即使分配器50被颠倒保持，分配器仍将产生相同质量的泡沫。
