A printer supply system with an ink filter system, including an ink holding chamber and a negative pressure generating unit chamber, and a negative pressure generating unit with an ink outlet at the bottom of the gravity direction. The ink accommodating chamber is connected to the bottom of the negative pressure generating unit on the bottom, and the negative pressure occurs in the upper and lower cross section of the chamber. Gradually decreasing, the material filled in the bearing chamber and the ink outlet of the negative pressure generator is a porous material formed in one. The density gradient is formed from the upper to the bottom. The density of the material in the outlet of the ink outlet is the highest and the printer system of the ink filter system has the function of the ink supply system. The ink box is simple in structure, reliable in performance, and with large ink capacity. It is convenient to make and low in cost. The invention provides ink directly to the sponge cavity through the ink supply channel on the partition board, and does not need to open the ink supply channel on the two sides of the bottom shell so as not to weld the sealing side film, so that the structure of the cartridge is simple and the cost is reduced, and the manufacturing cost of the development die of the cartridge box is reduced.

具有出墨滤嘴系统的打印机供墨系统
本专利技术涉及墨盒,尤其是一种用来为喷墨打印机供应墨水的墨盒。
技术介绍
在市场上一种比较常用的打印机墨盒中,其出墨口装有一个具有出墨滤嘴系统的打印机供墨系统,出墨口上方的腔体内装有多孔材料吸附墨水,在打印头的负压作用下,墨水从多孔吸附材料释放至具有出墨滤嘴系统的打印机供墨系统,经打印头的喷嘴打印到媒介上形成文字和图案,为使打印流畅并减少残墨量,通常放置两块密度不同的多孔材料从而形成“密度台阶”,上面一块密度较小对墨水吸附能力较弱,下面一块密度较大对墨水吸附能力较强,这种结构的墨盒材料成本和组装成本都比较高,且具有出墨滤嘴系统的打印机供墨系统和多孔材料是分开设置的,制造工艺繁杂,组装成本也比较高。因此需要提供一种改进的墨水瓶装置以克服上述缺陷。
技术实现思路
本专利技术的目的是为了解决现有技术中打印机墨盒所存在的缺陷,提供一种性能稳定、材料成本低、结构简单且便于制造的打印机墨盒。为了实现上述目的,本专利技术采用的技术方案是:具有出墨滤嘴系统的打印机供墨系统,包括墨水容纳腔和负压发生部件容纳腔,负压发生部件容纳腔沿重力方向的底部设有出墨口,墨水容纳腔与负压发生部件容纳腔在底部相互连通;所述负压发生容纳腔和出墨口内填充的是一体成型的多孔材料,该多孔材料从上到下具有密度梯度,出墨口部位材料的密度最高。优选地,所述负压发生部件容纳腔的横截面由上到下逐渐减小。优选地,所述多孔材料底部密度是上部密度的1.25—5倍,更合适的是在1.5倍到3倍之间。本专利技术所述的墨盒中,所述供墨通道为设置在所述隔板中上的多个规则排列的通孔,所述通孔连通所 ...
