Embodiment Construction

[0031] like figure 2 The shown ink cartridge for an inkjet printer includes a box body, a detection mechanism for detecting the ink cartridge and the remaining amount of ink, and the box body includes an ink storage chamber for storing ink and an ink outlet for supplying ink to the print head of the printer. port 7 and atmospheric inlet 2, the ink storage chamber includes a first ink chamber 20 and a second ink chamber 21, a gravity valve 9 and a buoyancy valve 8 are arranged between the first ink chamber 20 and the second ink chamber 21, and the gravity valve 9 and The buoyancy valve 8 cooperates to control the ink in the first ink chamber 20 to be consumed preferentially over the ink in the second ink chamber 21. The buoyancy valve 8 generates negative pressure only when the ink in the ink storage chamber prints to a certain amount. The atmospheric inlet 2 is set at on the first ink chamber 20 .

Abstract

The invention relates to an ink box of an ink jet printer. The ink box comprises a box body and a detecting mechanism for detecting the ink box and the surplus quantity of ink, wherein the box body comprises an ink storage cavity for storing ink, an ink outlet for supplying ink for a printing head of the printer and an atmosphere inlet; the ink storage cavity comprises a first ink cavity and a second ink cavity, and a first negative pressure mechanism and a second negative pressure mechanism are arranged between the first ink cavity and the second ink cavity; the first negative pressure mechanism and the second negative pressure mechanism are matched to control the ink in the first ink cavity to be consumed more preferentially than the ink in the second ink cavity; and the second negative pressure mechanism ensures that negative pressure is generated when the ink in the ink storage cavity is used to a certain quantity. Because the negative pressure is not generated when the ink in the ink storage cavity is not used to a certain quantity, the negative pressure is generated only when the surplus quantity of the ink is less in the end, and the technical problems that parts in the ink box are easy to damage and deform because the negative pressure exists all the time in a using process and the printing quantity is influenced cannot occur.

Description

technical field [0001] The invention relates to an ink cartridge on an ink jet printer. Background technique [0002] The ink cartridges of the existing inkjet printers are equipped with a negative pressure mechanism in the ink cartridge, which can generate negative pressure inside the ink cartridge, but the negative pressure is generated at the beginning of the ink cartridge printing, and it is maintained until the ink is consumed. However, when the ink cartridge is in a negative pressure state for a long time, it is easy to suck out the ink of the print head, resulting in damage to the print head and affecting the print quality. [0003] There is also a class of inkjet printers that use an off-axis ink supply design. This type of printer has a replaceable ink tank located below the print head. A suction pump is used to pump ink into the non-replaceable ink tank above the print head. The ink cartridge above the head communicates with the nozzle and has a negative pressure ...
