Ink cartridge and its closure assembly for continuous ink supply systems

The present invention relates to an ink cartridge, and more particularly to an ink cartridge and a closure assembly thereof for a continuous ink supply system having a gas permeable, double-layered seal and a pressure balance between internal and external.

In general, inkjet printers are popular among consumers because of their ease of operation and can be printed on a variety of inkjet media. However, inkjet printers use ink cartridges for a period of time. When you need to change the ink cartridges, the common replacement method is to discard the old ink and install a new ink to provide ink. This not only causes waste of the ink cartridge, but also invisibly increases due to the high price of ink cartridges. The user's overhead. In order to save printing costs and avoid waste of resources, a continuous ink supply system that reuses the same ink cartridge can be used.

The existing continuous ink supply system is an external continuous ink supply system, which is provided with a printing ink body outside the ink jet printer, and the ink cartridge inside the inkjet printer and the ink jet printer are connected by a pipeline. Using the principle of vacuum ink guiding, the ink is introduced into the ink cartridge from the printing cartridge, and then the ink consumption of the printing cartridge is visually observed to timely replenish the ink into the printing cartridge, thereby achieving ink ink supply. Intermittent continuous ink supply.

The ink refilling method of the conventional printing cartridge is injected into the printing cartridge by the ink introduction port provided at the top of the printing cartridge, so that the ink is gradually diffused downward from the top to the bottom of the printing cartridge, so the amount of ink injected The ink must be accumulated to a certain extent before the ink is supplied, and the speed of the ink replenishment must be greater than the speed of the ink supply of the printing cartridge. Otherwise, the ink supply will be slow, and the ink jet speed of the ink jet printer will be seriously affected. And print quality.

In addition, the squirt body of the commercially available continuous ink printer has a pressure regulating mechanism, and the pressure inside the squirt body is adjusted by the pressure adjusting mechanism to avoid high and low temperature difference during the process of transporting the ink and the process of conveying. The vibration generates internal pressure to reduce the overflow of the ink due to internal pressure. However, the aforementioned pressure regulating mechanism does not adjust the internal pressure very quickly, and cannot accurately adjust the internal pressure difference to be exactly the same as the external pressure. Once the internal pressure is generated in the ink cartridge, the pressure regulating mechanism cannot adjust the inside and outside in time. The pressure difference, the ink will still have doubts about overflow.

Furthermore, some of the commercially available continuous ink supply printers have a sneezing system in which the ink guiding needle is embedded, and a sealed space is created by inserting the ink guiding column to allow the ink to flow without overflowing. The assembly process of the setting method is complicated, and the pre-buried ink guiding column is easily skewed by the pressure, and it is also difficult to replace the embedded ink guiding column, resulting in poor ink guiding effect.

In view of this, how to develop an ink cartridge which can improve the lack of the aforementioned prior art is an urgent problem to be solved.

The main purpose of this case is to improve the ink refilling method of the conventional continuous ink supply printer, which is easy to cause ink overflow, and to solve the problem that the pressure regulating mechanism of the conventional continuous ink supply printer cannot adjust the internal and external pressure difference in time, and avoid continuous The ink supply printer must pre-embed the ink guiding needle in the body to cause complicated assembly process and easy deflection of the ink guiding column, and efficiently perform continuous fast ink supply operation.

In order to achieve the above object, one of the more broad aspects of the present invention provides an ink cartridge suitable for use in a continuous ink supply system comprising: a cartridge; and a lid assembly comprising: a lid corresponding to the cartridge And at least one venting hole penetrating through the cover body and at least one venting hole extending through the cover body; at least one positioning buckle ring correspondingly fixedly disposed on the at least one ink supply hole; at least one rubber ring correspondingly fixed Provided in the at least one ink supply hole; to a metal ink guiding column, which is integrally formed in the at least one ink supply hole, has an ink guiding flow path inside, and has an ink guiding hole on the column wall at the end; and at least one a film structure correspondingly fixedly disposed at each of the ink supply holes to close the ink supply hole; when continuous ink supply is to be performed, the at least one metal ink guiding column corresponds to the at least one ink supply to be disposed And puncturing the film structure disposed in the hole, so that the at least one metal ink guiding column is disposed in the at least one ink supply hole, and is engaged with the at least one positioning buckle, and the at least A metal ink guiding column is in communication with a continuous ink supply device for continuous ink supply.
