Description of the invention: [Technical field to which the invention pertains] The present invention relates to a printing ink cartridge and a venting structure to which it is applied, and more particularly to a printing ink cartridge suitable for a continuous ink supply system and a row thereof to which it is applied Gas structure. [Prior Art] ❹ 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 will be used for a period of time. When the ink of the ink E is exhausted and the ink needs to be replaced, the common replacement method is to discard the old ink and install a new ink to provide the ink, which not only causes waste of the ink cartridge, but also the price of the ink cartridge. Expensive and intangible increases the user's overhead. In order to save printing costs and avoid waste of resources, the continuous ink supply system that reuses the same ink cartridge is born. ❹ The existing continuous ink supply system is an external continuous ink supply system, which is provided with an ink supply cartridge outside the inkjet printer, and connects the ink supply cartridge and the inkjet printer inside the inkjet printer through a pipeline.匣, using the principle of vacuum ink guiding, the ink is introduced into the ink cartridge from the ink supply cartridge, and then the ink consumption of the ink cartridge is visually observed to timely replenish the ink into the ink cartridge, thereby achieving the printing ink cartridge. Ink supply for continuous ink supply. However, the above continuous ink supply system has many limitations and inconveniences in its use. First, the height of the ink supply must be on the same plane as the inkjet printer, and the ink level of the ink supply must be slightly lower than that of the inkjet printer, 6 200924987 to avoid printing ink from the supply. The ink is too large to cause the ink to overflow from the ink outlet. However, after standing for a period of time, the printing ink cartridge often returns to the ink supply cartridge due to its high ink level, which not only seriously affects the ink supply state, but also wastes a certain amount of ink when re-used. Ink and ink pressure restores balance and smooth ink supply. Secondly, because the position of the ink supply cassette is concealed, the user is prone to make up the ink. When the ink of the ink supply is used up, the ink supply of the ink supply cannot be normally supplied, and even the printing may be blocked due to lack of ink drying. The ink outlet of the ink. Furthermore, the assembly of ink cartridges, ink cartridges and pipelines is complicated. If improper installation of the pipeline will affect the movement of the ink cartridge carrier, the printing quality will be reduced, and if the pipeline is loose, it will cause ink leakage and entanglement. The pipeline also affects the aesthetics of the exterior of the inkjet printer. In addition, the conventional ink jet top has a small hole for eliminating excess gas inside the ink jet and balancing the pressure inside the ink jet, however, when the continuous ink supply system is operated, when the ink is continuously When injected into the ink cartridge, the pressure inside the ink cartridge is changed, but since the opening is in communication with the outside, the airtightness in the ink cartridge is affected, and even leakage through the opening is easily caused. In the case of ink, the service life and print quality of the ink cartridges will be reduced. In view of this, how to develop a printing ink cartridge suitable for the continuous ink supply system and the exhaust structure to which it is applied, which can improve the above-mentioned conventional disadvantages, is an urgent problem to be solved. SUMMARY OF THE INVENTION The main purpose of the 200924987 f case is to provide a printing ink cartridge and an exhaust structure suitable for the same, which solves the conventional technique by printing a small hole in the top of the ink to exclude the ink cartridge.
