摘要： A seal part for an ink cartridge of an inkjet printer including a seal end for sealing an ink outlet port of the ink cartridge is provided. The seal part is column-shaped, a cylindrical cavity exists inside the seal part, and a diameter of the cavity is greater than a diameter of an ink supply needle of the printer. The seal end for sealing the ink output port of the ink cartridge is a cylindrical surface, or is a cylindrical surface having at least a circle of sealing flange. One end surface is a closed plane for preventing the ink from flowing out from the ink outlet port after the ink cartridge is detached from the printer, and the other end surface is a plane with an aperture in the center. The size of the aperture is adequate to seal the ink supply needle of the printer. The seal part seals the ink supply needle of the printer after the ink cartridge is installed in the printer, and prevents the ink leakage after the ink cartridge is detached from the printer.
摘要翻译：提供一种用于喷墨打印机的墨盒的密封部分，其包括用于密封墨盒的墨水出口的密封端。密封部分为柱状，密封部分内部存在圆柱形空腔，空腔的直径大于打印机的供墨针的直径。用于密封墨盒的墨水输出口的密封端是圆柱形表面，或是具有至少一圈密封凸缘的圆柱形表面。一个端面是一个封闭平面，用于在墨盒从打印机上拆下之后防止墨从墨出口流出，而另一端表面是具有中心孔径的平面。孔径大小足以密封打印机的供墨针头。在将墨盒安装在打印机中之后，密封部分密封打印机的供墨针，并防止墨盒从打印机上拆下后泄漏墨水。
