Technical Field

[0001] The utility model relates to the technical field of printing equipment, in particular to an ink cartridge which is capable of filling ink into the back of the ink cartridge and has an automatic filling function. Background Art

[0002] An ink cartridge is a supporting device for supplying ink to a printer. An ink cartridge mainly refers to a component in an inkjet printer that is used to store printing ink and ultimately complete printing. From the perspective of the composition structure of ink cartridges currently on the market, in general, they can be divided into: split ink cartridges and integrated ink cartridges. An integrated ink cartridge has the nozzle integrated into the ink cartridge. When the ink is used up and a new ink cartridge is replaced, it also means that a new print head is replaced at the same time. With the continuous development of technology, people's requirements for the manufacturing process of ink cartridges are becoming higher and higher.
