Ink cartridge for color printer

Abstract

The invention discloses an ink cartridge for a color printer. The ink cartridge comprises a cartridge body. The cartridge body is provided with an ink outlet for guiding out ink. A connecting base isarranged on the cartridge body. The connecting base is provided with a pipeline which communicates with the ink outlet and inclines upwards. The pipeline is provided with a closing mechanism for preventing the ink from leaking out. A water sucking body sucks the ink in the cartridge body for storing. A piston carries out conveying. It can be ensured that the ink has certain pressure when the ink is provided, the influence of outside environment is avoided, and ink supply is continuous. The pipeline is arranged in an inclination shape, and thus excessive ink can flow back into the water suckingbody to be stored. When the piston slides toward one side of a cavity in the cartridge body, the excessive ink in the pipeline can be sucked back into the water sucking body, and thus the situation that a large amount of ink in the pipeline deposits, and blocking is caused can be prevented.

Description

technical field [0001] The invention relates to the field of office supplies, in particular to an ink cartridge for a color printer. Background technique [0002] At present, printers are an indispensable item in the office. There are various types of printers on the market, especially for some color printers, because they need to carry different colors of ink, color printers need to be equipped with different ink cartridges to meet the requirements of the printer. work. [0003] The ink cartridges of current color printers are generally equipped with a one-way valve at the ink outlet. When the ink is discharged, it will flow automatically by gravity. However, when a certain amount is used, the ink cannot be delivered normally due to insufficient pressure. The pipeline of the tube is relatively thin, and it is very troublesome to control the ink delivery by gravity. When the internal and external air pressure of the ink cartridge is different, the ink cannot be delivered, a...

[0003] The ink cartridges of current color printers are generally equipped with a one-way valve at the ink outlet. When the ink is discharged, it will flow automatically by gravity. However, when a certain amount is used, the ink cannot be delivered normally due to insufficient pressure. The pipeline of the tube is relatively thin, and it is very troublesome to control the ink delivery by gravity. When the internal and external air pressure of the ink cartridge is different, the ink cannot be delivered, and the ink delivered to the pipeline cannot be returned. When it is not used for a long time, it will Situations that lead to clogged pipes
