Description

Technical Field

[0001] The utility model relates to the field of ink cartridges, in particular to an integrated ink cartridge for an inkjet printer. Background Art

[0002] A printer is one of the output devices of a computer, which is used to print the computer processing results on related media. Common printers include laser printers and inkjet printers. Laser printers have fast printing speeds and low failure rates, but the cost of color printing is relatively high. Inkjet printers have bright colors, good effects, and relatively low printing costs. Inkjet printers are usually chosen for color printing.

[0003] Ink cartridges are devices used to store and supply ink in printers and are a type of printer consumables. The quality of ink cartridges directly affects the effect of printed output, such as the clarity of text and the vividness of images. Ink cartridges are usually divided into two types: integrated and split. Split ink cartridges separate the nozzle and ink cartridge design, while integrated ink cartridges integrate the nozzle on the ink cartridge. When the ink runs out and a new ink cartridge is replaced, it also means replacing a new print head at the same time, which can achieve relatively high printing accuracy, but the cost is higher.

[0004] Existing integrated ink cartridges are usually provided with an ink filling port on the box cover, and a label with the ink cartridge information is pasted on the surface of the box cover. When the label is pasted on the surface of the box cover, the ink filling port is closed to prevent ink from leaking from the ink filling port. When the ink is used up, the user can buy ink and tear off the label by himself with a syringe to add ink to the ink cartridge from the ink filling port without replacing the ink cartridge. However, the label is connected to the box cover with glue. After the label is torn off and then pasted again, the viscosity will decrease, resulting in incomplete adhesion, which may easily cause ink to leak from the ink filling port, and the label may be torn and cannot be pasted again.
