Description

一种用于墨盒的灌墨装置 技术领域
本发明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2010年08月05日提交中国专利局、申请号为201020282868.2、名称为“一种用于墨盒的灌墨装置”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。
背景技术
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。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: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，而这个一体式的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: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上盖的灌墨孔溢出。
现有灌墨方法的缺点总结：
1、海绵式墨盒使用以上的方法易出现加墨不均匀的情况；
2、操作控制不当易使墨水外漏，弄脏衣服和手；
3、用钻头扩充墨盒空间时需掌握力度；
4、采用注射器或弹簧瓶填充时，回抽不灵活；
5、使用的辅助工具多，操作复杂；
6、上机后常出现漏墨、打印机不认墨盒等问题；
7、金属芯片上墨水擦拭不干净，容易引起打印机短路。
 技术问题
本发明所要解决的技术问题在于针对现有技术的缺陷，提供一种用于墨盒的灌墨装置，其使用方便、干净卫生且填充效果好。
技术解决方案
为解决上述技术问题，本发明采用了以下的技术方案：设计一种用于墨盒的灌墨装置，所述墨盒的顶部具有灌墨孔，底部具有喷嘴，其特征在于：所述灌墨装置包括底座、连接于该底座的上盖和容纳墨水的灌墨容器，所述底座内具有用于放置所述墨盒的墨盒容纳腔，所述上盖设有用于与所述灌墨容器的出墨口对接的灌墨接口和用于插入所述灌墨孔的灌墨针，所述灌墨容器为可对所述墨盒预先抽气的负压灌墨容器。
　　优选地，所述墨盒容纳腔的底部设有用于在灌墨时密封所述喷嘴的密封垫，该密封垫固定在所述底座上。所述密封垫可以为硅胶垫。
　　所述灌墨针上最好设有用于在灌墨时密封所述灌墨孔的密封件。
　　所述上盖的底部还设有可沿所述灌墨针的轴向移动的灌墨针保护板，该灌墨针保护板上具有可供所述灌墨针穿过的通孔。所述上盖设置有与所述灌墨针保护板配合的导柱，所述导柱上套有弹簧。
　　所述负压灌墨容器可以为内部具有负压的灌墨瓶，该灌墨瓶上具有在灌墨时撕下的导气膜。此外，所述负压灌墨容器还可以为注射器，该注射器包括外筒和可在该外筒内往复移动的推杆。所述推杆可以为实心杆或空心杆，为空心杆时，其内的空腔与所述外筒的内腔相连通。
 有益效果
本发明的的灌墨装置具有以下的优点和有益效果：
　　1、在灌墨过程中，无需用户接触墨水，不会弄脏用户的手和周围的环境。
　　2、灌墨过程中，墨盒的喷嘴朝下，能更好地保证把喷嘴和滤网下面的供墨柱内墨水灌满，达到良好的打印效果。
　　3、灌墨采用负压进行灌墨，灌墨量是墨盒腔体能吸进去的墨水量，不会少灌或多灌，不会出现冒墨和喷嘴漏墨的现象，并且灌墨效果也更好。

 本发明的实施方式
实施例一
　　参见图1至图6，实施例一的灌墨装置包括了用于直立地放置墨盒1的底座2、连接于该底座2的上盖3和容纳墨水的灌墨瓶4。该墨盒1的顶部具有三个灌墨孔11，底部具有喷嘴12，墨盒1的内部具有储墨腔13。底座2具有由底板21和若干个侧壁围成的墨盒容纳腔22，该墨盒容纳腔22的上部为开口结构，其中较长的两个侧壁23、24的内侧各平行设置有一块定位板221、222，定位板221与侧壁23之间形成定位槽223，定位板222与侧壁24之间形成定位槽224。墨盒容纳腔22的底部设有用于在灌墨时密封墨盒1的喷嘴12的硅胶垫25，该硅胶垫25固定在底板21的内壁面上。底座2的上部两端侧各设有一个扣位26。
　　上盖3具有顶板31和侧壁32，侧壁32可由墨盒容纳腔22的上部开口插入，并与墨盒容纳腔22内的定位槽223、224配合。所述顶板31的两端侧各设有一个扣件311，每个扣件311上各具有一个可与扣位26配合的扣孔312。顶板31上插设有三根灌墨针33，此三根灌墨针33可由墨盒1顶部的三个灌墨孔11插入墨盒1内部的储墨腔13，以建立灌墨通道。灌墨针33上设有用于在灌墨时密封灌墨孔11的密封件35。顶板31在对应于三根灌墨针33的位置还设有三个呈管状的灌墨接口34，灌墨时，灌墨针33的顶部通过灌墨接口34与灌墨瓶4底部的出墨口41对接。
　　灌墨瓶4为一个内部预先抽有负压（例如为-90KPA）的负压灌墨瓶，以便在灌墨前对墨盒1预先抽气，灌墨瓶4的顶部设有导气槽44和用于将该导气槽44密封的导气膜42，该导气膜42在灌墨时应撕下，灌墨瓶4底部的出墨口41内设有密封塞组件43。在灌墨时，只要将灌墨瓶4底部的出墨口41与灌墨接口34对接，使灌墨针33的顶部穿过密封塞组件43并插入到灌墨瓶4内部，带有负压的灌墨瓶4便会先抽出墨盒1的储墨腔13内的空气，然后再把灌墨瓶4上的导气膜42撕掉，在外界大气的压力下，灌墨瓶4内的墨水便会被自动吸入墨盒1内，完成墨水的灌注。
　　以下对本实施例一的使用方法进行说明：
　　1、把墨盒1喷嘴朝下地放入底座2的墨盒容纳腔22内, 墨盒容纳腔22内的硅胶垫25正好对应于喷嘴12而将其密封。
　　2、把上盖3插入底座2，上盖3上的灌墨针33插入到墨盒1的储墨腔13内，把上盖3上的扣件311扣到底座2的扣位26上，。灌墨针33上的密封件35把墨盒1顶部的灌墨孔11的周边密封。
　　3、把灌墨瓶4插到上盖3的灌墨接口34上，灌墨针33的顶部插入灌墨瓶4内而建立灌墨通道，由于灌墨瓶4内保持有负压，这时，墨盒1内的气体被抽到灌墨瓶4内，灌墨瓶4内有气泡冒起。
　　4、待不再冒气泡后，撕掉灌墨瓶4上的导气膜42，墨水将在外界的大气压力下灌到墨盒1的储墨腔13内。
　　5、其他的各颜色依次进行，最后完成三色墨盒的三个墨水腔体的灌墨。
　　实施例二
　　参考图7和图8，实施例二提供的灌墨装置在组成上与实施例一基本类似，同样包括了容纳墨盒1的底座2、上盖5和灌墨瓶4等，区别主要在于上盖5的结构。与实施例一相比，实施例二的上盖5在其上盖本体51的底部还设有可沿灌墨针53的轴向移动的灌墨针保护板52，该灌墨针保护板52上具有可供灌墨针53穿过的通孔521。上盖5设置有与灌墨针保护板52配合的两根导柱54，导柱54的顶部固定在上盖5的顶板55上，导柱54上套有位于顶板55与灌墨针保护板52之间的弹簧56。本实施例由于设置有灌墨针保护板52，在灌墨装置的安装过程中可以避免灌墨针外露伤人，使用起来更加安全。
　　实施例三
　　参见图9，本实施例三使用注射器6替代了上述实施例一和二的墨水瓶进行抽负压和灌墨，该注射器6包括外筒61和可在该外筒61内往复移动的实心推杆62。以下对注射器6的使用方法进行说明：
把注射器6插到上盖3的灌墨接口34上，拔起实心推杆62，把墨盒1的储墨腔13内的气体抽出来，注射器6内预先装有四分之一左右的墨水，可以看到有气泡冒起，表示在对储墨腔13抽负压。待把实心推杆62抽拉到外筒61的接近顶端时，松开实心推杆62，此时实心推杆62在外界的大气压力下往下走，注射器6内的墨水也被压到墨盒1的储墨腔13内。
　　实施例四
　　参见图10，本实施例使用注射器7进行抽负压和灌墨，该注射器7包括外筒71和可在该外筒71内往复移动的空心推杆72，该推杆72内的空腔721与外筒71的内腔711相连通。以下对注射器7的使用方法进行说明：把注射器7插到上盖3的灌墨接口34上，拔器注射器7的空心推杆72，把墨盒1的储墨腔13内的气体抽出来，外筒71内预先装有三分之一左右的墨水，可以看到有气泡冒起，表示在对储墨腔13抽负压。待把空心推杆72抽拉到外筒71的接近顶端时，松开空心推杆72，此时空心推杆72在外界的大气压力下往下走，注射器7内的墨水也被压到墨盒1的墨水腔13内。
　　以上所述的仅是本发明的优选实施方式，应当指出，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。
 工业实用性
采用本发明的灌墨装置进行灌墨时，无需用户接触墨水，不会弄脏用户的手和周围的环境；灌墨过程中，墨盒的喷嘴朝下，能更好地保证把喷嘴和滤网下面的供墨柱内墨水灌满，达到良好的打印效果。而且，本发明采用负压进行灌墨，灌墨量是墨盒腔体能吸进去的墨水量，不会少灌或多灌，不会出现冒墨和喷嘴漏墨的现象，并且灌墨效果也更好。
