Description

墨盒灌墨装置
本发明涉及打印机耗材，更具体地说，涉及一种用于给喷墨打印机墨盒补充墨水的灌墨装置。本申请要求于2011年09月01日提交中国专利局、申请号为201120326269.0、名称为“墨盒灌墨装置”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
目前市场上有很多喷墨打印机用的墨盒为一体盒，也就是将打印喷嘴与墨水容器集成在一起，一般为海棉墨盒的结构，又称为打印头。这类墨盒有一个特点，在用户用完了墨水后，可以对墨盒进行灌墨然后继续使用。
常用的灌墨方法有以下几种：
1、喷嘴灌墨法。厂家为用户设计并提供了齐全的附件，包括墨水瓶、墨盒盖、螺丝钉，让用户从墨盒的喷嘴对墨盒内注入墨水。这种方法的缺点在于，从喷嘴加墨水，将会使可能堵塞喷嘴的灰尘及其他大颗粒物质不经过墨盒过滤系统直接进入墨盒，假如兼容墨水质量不高，很可能造成喷嘴堵塞，使墨盒报废，而这种一体式墨盒如果使用原装墨水原本是应该具有较长寿命的。
2、扩孔灌注法。在各个墨盒上都有一个气孔，这是为了维持墨盒内部压力平衡而设计的呼吸器官。用户将墨盒上的气孔扩大，然后从此处灌注墨水。这种方法的缺点在于，如果气孔被扩大，造成气压调节功能失灵，墨水将从喷嘴溢出。破坏气孔，严重的将会使墨盒报废。
3、钻孔灌注法。墨盒本身除了喷嘴以外没有出墨口，气孔又不能破坏，所以只能使用钻孔灌注法。厂家为用户设计并提供了齐全的附件，有带有针头的墨水瓶、钻头、皮老虎（手风器）。这种方法的缺点在于，需要钻孔，操作麻烦；钻孔时易有细屑掉入墨盒内；需要的辅助工具较多；难以控制灌墨量，墨水很容易从喷嘴和面盖上的灌墨孔溢出。
因此，现有的各种灌墨方法主要存在以下一些缺点：
1、采用正压灌墨，容易出现墨水不能很好地充满供墨柱下面，从而造成打印条纹和断墨；
2、海绵式墨盒使用以上的方法易出现加墨不均匀的情况；
3、操作控制不当易使墨水外漏，弄脏衣服和手；
4、用钻头扩充墨盒空间时需掌握力度；
5、采用注射器或弹簧瓶填充时，回抽不灵活；
6、使用的辅助工具多，操作复杂；
7、上机后常出现漏墨、打印机不认墨盒等问题；
8、金属芯片上墨水擦拭不干净，容易引起打印机短路。
本发明要解决的技术问题在于，针对现有技术的上述缺陷，提供一种使用方便、干净卫生且灌墨效果好的墨盒灌墨装置。
本发明解决其技术问题所采用的技术方案是：提供一种墨盒灌墨装置，包括用于放置墨盒的底座、盛装墨水的墨水容器、负压源和可通过墨盒的灌墨孔插入墨盒内的灌墨针头，所述底座的下部设有密封墨盒的喷嘴的第一密封件，所述底座的上部设有密封墨盒的灌墨孔的第二密封件，所述灌墨针头的上端通过第一导管与墨水容器中的墨水连通，所述墨水容器的液面上部空间连接于所述负压源，并且所述液面上部空间还通过导气阀连接大气。
进一步的技术方案为，所述底座包括底板、从底板向上伸出的多个支柱、以及顶板，顶板通过向下伸出的多个套管套在相应支柱上，所述第一密封件设于所述底板的上表面，所述第二密封件设于所述顶板的下表面，所述灌墨针头穿设在所述顶板上。
较佳地，所述第一密封件和第二密封件为硅胶垫。
进一步的技术方案为，所述第一导管连接至墨水容器的底部。
进一步的技术方案为，所述液面上部空间通过第二导管连接于所述负压源。
较佳地，所述负压源为微型真空泵。
进一步的技术方案为，所述液面上部空间与引入大气的第三导管连通，所述导气阀设置在所述第三导管上。
本发明的墨盒灌墨装置先利用负压源对墨盒的储墨腔进行抽负压，到达一定的负压值后停止抽负压，通过大气把墨水容器内的墨水压入墨盒内，同时也是墨盒内的负压把墨水容器中的墨水吸到墨盒内。此种负压灌墨装置的优点在于：
1、先把墨盒密封，再抽去墨盒内空气，然后再让墨盒吸墨，到最后墨盒内压力依然和外界的大气压力平衡，因而不会出现少灌墨水和墨水多灌后溢出的情况。
2、使用负压源例如真空泵，抽负压更简单方便。
3、使用负压灌墨，墨水的分布情况更好，集中在灌墨针头附近，有利打印供墨。
4、墨盒喷嘴朝下，灌墨效果更好，有利于喷嘴上方的灌墨。
下面将结合附图及实施例对本发明作进一步说明，附图中：
图1是现有墨盒的立体结构示意图；
图2是图1所示的墨盒的剖视图；
图3是根据本发明一个实施例的墨盒灌墨装置的结构示意图。
为了使本发明的目的、技术方案及优点更加清楚明白，以下结合附图及实施例，对本发明进行进一步详细说明。应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
　　图1和图2分别示出了现有的喷墨打印机所使用的一体式墨盒10的立体结构图和剖视图。如图1和图2所示，墨盒10主要由储墨腔11、以及设于储墨腔11上部的面盖12和设于储墨腔11下部的喷嘴13构成，面盖12上设有多个灌墨孔14，储墨腔11内设置储墨海绵14。
　　为了给墨盒10灌墨，本发明提出了一种使用负压灌墨的墨盒灌墨装置。图3示出了根据本发明一个实施例的墨盒灌墨装置100的结构示意图。如图3所示，该灌墨装置100包括灌墨底座20、墨水容器40和负压源90。待灌墨的墨盒10以喷嘴朝下的方式放置于灌墨底座20中，墨盒10的喷嘴和面盖上的灌墨孔分别通过灌墨底座20上设置的第一密封件25和第二密封件26密封。灌墨针头27穿过密封墨盒10的面盖的第二密封件26并通面盖上的灌墨孔插入墨盒10内的储墨海绵中。灌墨针头27的上端通过第一导管30与墨水容器40的底部连通。墨水容器40中盛装大约一半容积的墨水50。墨水容器40内的液面上部空间41通过第二导管80连接负压源90，该负压源90可以是例如微型真空泵。此外，墨水容器40内的液面上部空间41还通过第三导管60连通大气，且第三导管60上设有导气阀70。
　　进一步如图3所示，灌墨底座20由底板21、从底板21向上伸出的多个支柱22、以及顶板23构成，顶板23通过向下伸出的多个套管24套在相应的多个支柱22上。底板21上表面对应墨盒10的喷嘴设有第一密封件25，顶板23下表面对应墨盒10的面盖设有第二密封件26。具体实施例中，该第一密封件25和第二密封件26可以选用硅胶垫。灌墨针头27穿设在顶板23上。当将墨盒10以喷嘴朝下的方式放置在底板21上之后，将顶板23向下压，从而将墨盒10固定在底板21和顶板23之间并通过第一密封件25和第二密封件26上下密封。
　　图3所示的灌墨装置100的工作过程如下：
　　第一步，将待灌墨的墨盒10放置入灌墨底座20中，由第一密封件25和第二密封件26分别将墨盒10的喷嘴和灌墨孔密封。
　　第二步，压下灌墨底座20上的灌墨针头27，将灌墨针头27通过墨盒10上的灌墨孔插入墨盒10内的储墨海绵中，优选将灌墨针头27插入到墨盒10内离滤网大约3-5mm处。
　　第三步，关闭墨水容器40上的导气阀70。
　　第四步，打开真空泵90进行抽负压。真空泵90会先抽出墨水容器40中的一部分空气，然后墨盒10内的空气经过灌墨针头27、第一导管30和墨水容器40被真空泵90抽出。当抽到一定的负压值（例如大约在-50KPA左右）之后，关停真空泵90。
　　第五步，打开墨水容器40上的导气阀70，将大气通过第二导管60引入墨水容器40中。此时，墨水容器40内的墨水50在外界大气压的作用下，经第一导管30和灌墨针头27被吸入到墨盒10的储墨海绵中。
　　大约十几秒钟后，吸入墨盒10内的墨水填补了被抽走的空气占据的空间，使得墨盒10内的压力与外界大气压保持平衡，不再吸入墨水，墨盒10完成灌墨。从灌墨底座20上取下墨盒10，便可以上打印机进行打印使用，简单方便。
　　以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本发明的保护范围之内。
本发明的墨盒灌墨装置可以在工业上制造和使用。本发明的墨盒灌墨装置利用负压灌墨，不会出现少灌或多灌后溢出的情况，墨水分布情况好，灌墨效果更好。因此，本发明具备工业实用性。
