Abstract

An ink cartridge for printer is disclosed which comprises a casing, a cover, and ink bags. Each kind of colorful ink is filled into its individual ink bag, which is mounted in the casing in an assembled manner. The ink bag has a negative-pressure mechanism for controlling the ink flow, and a flexible film is welded on a support for the ink bag. The ink contained in the ink bag flows into or out of an ink chamber via the negative-pressure mechanism during printing. There is not any air-intake system in the ink bag. The shape of the flexible film varies with the capacity of the ink bag. The ink contained in the ink bag should separate from air as much as possible, so that air couldn't enter into the ink-outlet.

打印机墨盒  Printer Cartridges
技术领域 Technical field
本实用新型涉及一种喷墨打印机用的带有储墨囊的打印机墨盒。 背景技术  The utility model relates to a printer ink cartridge with an ink storage bag for an inkjet printer. Background technique
目前出墨口有密封圈的喷墨打印机墨盒控制出墨量的方式， 主要有两种类型- 一种类型为用海绵储存墨水和海绵的毛细管的作用来控制打印。 墨盒用完后， 存在太多残余在海绵上的墨水， 造成一定的浪费和不利于环保， 同时成本增高。  At present, inkjet printer ink cartridges with a seal at the ink outlet have two types of ink control methods-one type uses a sponge to store ink and the function of a capillary tube to control printing. After the ink cartridge is used up, there is too much ink remaining on the sponge, which causes a certain amount of waste and is not good for environmental protection, and the cost increases.
另一种类型为无海绵方式， 其进气系统设计十分复杂， 同时墨盒结构复杂， 零 部件繁多，加工工艺流程多。由于其负压控制阀设置的高度以及墨水通道设计的原因， 同样会残留较多  The other type is the sponge-free method. The design of the air intake system is very complicated. At the same time, the structure of the ink cartridge is complicated, the number of parts is large, and the processing process is many. Due to the height of the negative pressure control valve and the design of the ink channel, there will be more residues.
墨水。 发明内容 ink. Summary of the invention
本实用新型目的是这样实现的： 一种带有储墨囊的打印机墨盒。 包括底壳、 面 盖和储墨囊。 各种颜色有单独的墨囊， 可以用装配方式装进底壳。 储墨囊上有负压机 构， 控制出墨口墨水流量。 储墨囊架两边焊有软膜， 软膜之间盛放墨水， 它们之间的 体积可以变化。 在打印过程中， 随着墨水量的消耗， 体积不断地变小。 墨水通过单向 阀流进出墨口腔。 出墨腔下面出墨口处设有密封圈、 单向阀芯及弹簧。 储墨囊上没有 任何进气系统， 最大限度地防止空气进入储墨囊内， 使墨水和空气相隔离， 避免气泡 进入出墨口。 在快速打印过程中， 打印性能稳定可靠， 打印质量提高。 附图说明：  The purpose of the utility model is achieved as follows: A printer ink cartridge with an ink storage capsule. Including bottom case, face cover and ink reservoir. There are separate ink sacs for each color, which can be assembled into the bottom case by assembly. There is a negative pressure mechanism on the ink storage bag to control the ink flow at the ink outlet. A soft film is welded on both sides of the ink storage bag holder. The ink is held between the soft films, and the volume between them can be changed. During the printing process, the volume becomes smaller as the amount of ink is consumed. Ink flows into and out of the mouth through a one-way valve. A seal ring, a one-way valve core and a spring are arranged at the ink outlet under the ink outlet cavity. There is no air intake system on the ink storage bag, which prevents air from entering the ink storage bag to the maximum extent, isolates the ink from the air, and prevents air bubbles from entering the ink outlet. In the fast printing process, the printing performance is stable and reliable, and the printing quality is improved. Brief description of the drawings:

如图 1所述， 本实用新型包括底壳 2、 面盖 1、 墨囊架 3、 每种颜色有单独墨囊， 每个墨囊包括一个负压机构， 它由阀弹簧 4、 阔膜 5、 阀圆盖 6组成， 墨囊架两边焊 有软膜 7， 墨水盛放在储墨腔 11。 储墨腔 11是由墨囊架 3和软膜 7共同组成， 是可 变体积的。 在墨盒的打印过程中， 随着墨水不断消耗， 储墨腔的体积不断变小。 储墨 腔 11的墨水通过墨水通道 12流进负压机构， 再由负压机构流进出墨口腔 13, 最终流 到出墨口 14。  As shown in FIG. 1, the utility model includes a bottom case 2, a face cover 1, an ink bag holder 3, and each color has a separate ink bag. Each ink bag includes a negative pressure mechanism, which is composed of a valve spring 4 and a broad film 5. The valve cover 6 is composed of a soft film 7 welded on both sides of the ink bag holder, and the ink is stored in the ink storage chamber 11. The ink storage chamber 11 is composed of the ink bag holder 3 and the soft film 7 and has a variable volume. During the printing process of the ink cartridge, as the ink is continuously consumed, the volume of the ink storage chamber is continuously reduced. The ink in the ink storage chamber 11 flows into the negative pressure mechanism through the ink channel 12, and then flows into and out of the ink oral cavity 13, and finally flows to the ink outlet 14 through the negative pressure mechanism.
