摘要： The ink cartridge comprises a cartridge body with an ink chamber. On one side of the cartridge body is provided an ink supply port, and an air channel is positioned on the opposite side. The ink chamber is composed of a main chamber and a communicating sub-chamber, an ink-out inspection prism being provided close to the communicating portion. A check valve through which the sub-chamber is communicated with the ink supply port is provided sideways between the side walls adjacent to the ink supply port. In this invention, the nominal volume of each ink cartridge is increased, and there is no such problem that a certain amount of ink continues to be fed after the ink-out indicative signal being sent out in case of no porous material. Further, the technical solution of the sideways-provided check valve improves the manufacturability and the ink supply stability.
摘要翻译：墨盒包括具有墨水室的墨盒本体。在盒体的一侧设置有供墨口，空气通道位于相对侧。墨水室由主室和连通副室构成，在该连通部附近设有防墨检查棱镜。在与供墨口相邻的侧壁之间侧面设置有与副供墨口连通的止回阀。在本发明中，每个墨盒的标称体积增加，并且没有在没有多孔材料的情况下发出墨水指示信号之后继续供给一定量的墨水的问题。此外，侧面提供的止回阀的技术方案提高了可制造性和供墨稳定性。

摘要： A valve body provided in ink chamber of the ink cartridge comprises a supporting foot, a supporting wall projected obliquely from the inside of the supporting foot, a supporting shoulder curved from the supporting wall towards the inside, and a supporting head with a central hole therethrough projected from the supporting shoulder. A valve seal means seals the central hole, and makes the ink being maintained. A seal member provided at the ink outlet port includes an integrally formed supporting portion which fits into the ink outlet port closely, a seal annular portion projected from the supporting portion, a block cooperating with the annular portion, and a connecting portion surrounding between the block and the annular portion. The valve body has an annular and staged configuration, which makes it sensitive to pressure, and at the same time, the seal member of the present invention acts well during use and non-use.
