Abstract

本发明涉及一种用于喷漆枪的可闭合混合容器的盖，该盖设有一通气口，通气口形成为具有相互嵌入的、且其彼此间允许空气流动的外圆管体、内圆管体和圆管件的一迷宫式曲折状密封结构。

Description

用于喷漆枪的混合容器的盖
技术领域
本发明涉及一种用于喷漆枪的可闭合混合容器的盖，此盖设有一通气口。
背景技术
以一次性盖形式形成的用于喷漆枪的可闭合混合容器的盖为已知的(德国专利29825119U1)。所述盖配置在开放的混合容器上，盖的底部有一气孔，且设有配合容器的一次性衬里。此一次性盖压入一次性衬里的开放端，且其中心开口通过一插销接头连接至一连接管。
另一种用于喷漆枪的可闭合混合容器的盖(德国专利公开案102004007733A1)是已知的，其包含一连接件以在喷漆枪上放置一流量杯或放置一转接头，此容器包含可由一阀闭合的通气口。
至今，在使用喷漆枪后，实际上通常需要利用溶剂(氯代烃)来高价清洁和/或洗涤喷漆枪与其喷漆枪杯。因此产生数百万升的污染的溶剂(清洁稀释液)。由于喷漆枪杯具有由油漆润湿的最大表面，因而几乎90％的清洁稀释液耗费与此杯有关。
有一种所谓的袋系统，在该系统中将一个壁厚非常薄的杯(类似一个袋)放置在一个可再使用的杯内。接着，将一个盖螺锁在此系统上，且接着头朝前地与喷漆枪连接。在喷漆时，此“袋”中产生低压且此袋收缩。该系统有两个严重的缺点。第一，需要一个额外的混合杯将不同油漆组分混合在一起。因此产生额外的成本，且必须将两个杯抛弃或回收；第二，“袋”中产生的低压会改变喷漆枪的喷洒模式。这意指此“袋”收缩量越大，从喷漆枪中喷出的漆越少。
再者，下述混合杯系统被付诸实践，其中使用一特殊的漆混合杯作为基础，油漆组分在漆混合杯中混合。漆混合杯装设一个盖，且头朝前旋转并与喷漆枪连接。在喷漆时，此杯中产生低压。所述低压阻碍油漆均匀地流动到喷漆枪，因而在杯的底部安装一个手动阀。此阀必须由喷漆者打开(当他要喷漆时)或关闭(当他将杯底朝下放置时)。但是此操作常会被忘记，使得油漆会流出此杯，或者喷漆枪会开始不灵活。因此这种系统中的制造成本非常的高。
发明内容
在此本发明提供一解决方案且其应该满足下列标准：
所需要的部件的制造必须是有成本效益的。
可以不需要一个手动阀。
必须可用在现有的混合杯系统上。
不需依赖会改变喷洒模式的低压。
本发明可达到这些标准，即通过用于喷漆枪的可闭合混合容器的盖，此盖设有一通气口，其特征在于通气口形成为具有三个相互嵌入的、且其彼此间允许空气流动的外圆管体、内圆管体和圆管件的一迷宫式曲折状密封结构。
在较佳实施例中，在相互嵌入的外圆管体、内圆管体和圆管件彼此相邻的至少一周缘表面上形成有沟槽或槽道，此沟槽或槽道特别地沿着外圆管体、内圆管体和圆管件的轴向延伸。
详细言之：此盖为可简单地扣合在现有的混合杯系统上。此盖有一通气系统，其在制造上非常简单，但是日常使用上可提供很大的利益。喷漆者不再需要思考如何关闭或打开阀。在混合杯装设此盖之后，它也是头朝前地旋转并连接在喷漆枪上。大气压力通过一特殊的通气道延伸到杯内。在此，此特征在于油漆在“翻转过程”不会从通气道泄漏。为此目的发明了一新颖的通气道几何形状，其实质运行像一个迷宫式曲折状密封结构。
通气口中的圆管状迷宫式密封结构本身为已知的，然而其并未与喷漆枪的混合容器盖相结合。因此在用于传动器的防溅水和防爆炸的通气件的通气槽上，迷宫式密封结构为已知的(DD 73432A)。再者，有一油箱密封结构(DD 6851A)其通过一横向部件安装至一油箱注油管，以允许外界空气通过一迷宫式密封结构进入到此油箱内。
以下，使用附图示例性地解释本发明。
附图说明
图1为用于喷漆枪的混合容器的盖的剖视图。
图2为迷宫式密封结构的细节图。
具体实施方式
10表示基本圆锥形的盖。其为一旋转对称部件。可以看出，此部件在边缘区域装设在未示出的混合杯上。9表示可以与喷漆枪连接的部件。
在本发明中，在盖10上显示有延伸到混合杯内部空间的一双圆管体设计。提供一外圆管体11，其与此盖一体成型。一较小的内圆管体12设在所述较大的外圆管体11中，且也与盖10一体成型。内圆管体12朝向顶端开放。
一盖件13设置在外圆管体11和内圆管体12的底端，且包含向上延伸的一圆管件14。该圆管件14的长度小于外圆管体11和内圆管体12的轴向长度。它的壁厚尺寸设为可利用些微间隙插入外圆管体11和内圆管体12之间的空间。形成具有盖件13的圆管件14，盖件13从底端封闭内圆管体12的内部空间，但没有完全密封。空气可经由位于内圆管体12底端的内圆管体12进入外圆管体11和内圆管体12之间的空间，即在圆管件14的位置。空气从此底端向上(在图的观看方向)能通过圆管件14且再向下流通，且由于盖13的具体形状使得在底端空气能再次进入到未示出的混合杯的内部空间20，亦即，形成从此混合杯及/或盖10的外部空间到此混合杯的内部空间20的气桥。如果个别的尺寸够小，此气桥将很容易可形成。然而，位于内部空间20中的油漆液体不能穿透此通气道到达外部。在一方面，由于在操作期间存在相应的低压，且另一方面由于液体的粘性使其无法通过该通气道。液体最多只能进入位于外圆管体11与圆管件14外部空间之间的空间一小截的距离，而不会影响使用性。
从图2中可以非常好地辨识流量比率，在此其为图示，而非真实比率的描绘。
在相互嵌入的圆管体彼此相邻的至少一周缘表面上可以形成有沟槽或槽道，并且特别地，此沟槽或槽道沿外圆管体、内圆管体和圆管件的轴向延伸。
