Description

Technical Field

[0001] The utility model relates to the technical field of printer ink cartridges, in particular to an integrated continuous ink supply cartridge structure. Background Art

[0002] Printer cartridges are an indispensable key component in inkjet printers, used to store and spray the ink required for printing. Ink cartridges are divided into integrated ink cartridges and split ink cartridges. Integrated ink cartridges mean that the nozzle is integrated on the ink cartridge. Replacing the ink cartridge means replacing the print head, which has the advantage of high printing accuracy. In order to reduce the frequency of replacing integrated ink cartridges, continuous ink supply can be used to provide continuous ink supply to the ink cartridge.

[0003] An integrated continuous ink supply cartridge generally consists of two ink cartridges, which are divided into an outer cartridge and an inner cartridge. The outer cartridge and the inner cartridge are connected by a delivery tube. The inner cartridge is installed in the printer, and the outer cartridge is hung outside. The large-capacity outer cartridge is used to supply ink to the inner cartridge to form a continuous supply. In the prior art, the ink in the outer cartridge needs to be added manually, and the outer cartridge needs to be opened each time for adding, so that the outer cartridge is exposed to the air. This may cause dust in the air or the added ink to be contaminated with dust and other particles and cannot be detected and added to the outer cartridge in time. When supplying ink, the ink with particulate impurities will enter the inner cartridge, blocking the inkjet port of the inner cartridge, thereby reducing the printing effect. Therefore, we disclose an integrated continuous ink supply cartridge structure to meet people's needs. Utility Model Content

[0004] The purpose of the present application is to provide an integrated continuous ink supply cartridge structure to solve the problem proposed in the above-mentioned background technology that the ink in the outer box needs to be added manually, and each time the outer box is opened to expose the outer box to the air, which may cause dust in the air or the added ink to be contaminated with dust and other particles to be unable to be discovered in time and added to the outer box. During the ink supply, the ink with particulate impurities will enter the inner box, blocking the inkjet port of the inner box and thus reducing the printing effect.
