Embodiment Construction

[0022] like Figure 1-3 Shown, a kind of recovery method of inkjet printer ink box, described ink box 1 comprises: ink storage chamber 2, can hold the ink that supplies to inkjet printer printhead; The ink in 2 is supplied to the print head; the valve mechanism 4 is set in the ink supply port 3 and consists of a valve core, a spring and a sealing ring. When the ink cartridge is not installed on the printer, it will Under the action of the elastic force of the spring, the valve mechanism is in a closed state. When the ink cartridge is installed on the printer, the ink supply needle on the printer cooperates with the ink supply port, and at this time the When the insertion force of the ink needle is greater than the elastic force, the valve mechanism is opened; the air communication channel 5 communicates the ink storage chamber with the external atmosphere, and has a gas-liquid separation membrane 6 and a through hole 7 on it, and the gas-liquid Separation membrane 6 is formed...

Abstract

The invention relates to a method for recycling ink box with differential pressure valve. The method comprises the following steps: (1) removing gas-liquid separation membrane, sealing through holes, and opening a new small hole communicating with an ink storage chamber on the ink box; (2) injecting proper amount of ink through the small hole; (3) sealing the small hole and pumping proper amount of ink back through an ink supplying port. Ink is injected through the small hole when being recycled, and when the recycled ink box is used for printing, the small hole can be used as an air inlet hole to lead external air into the ink box, thus ensuring air inlet to be smooth and printing to be smooth, avoiding ink leakage when ink flows backwards, solving the technical problems that existing method for recycling ink box with differential pressure valve is complicated and that the recycled ink box is easy to leak. The invention also provides an ink box recycled by the above recycling method.

Description

technical field [0001] The invention relates to a recovery method of an ink box with a differential pressure valve and the recovered ink box. Background technique [0002] At present, a split type ink cartridge is commonly seen on the market, which mainly includes: an ink storage chamber for storing ink, an ink supply port for supplying ink to the print head, and an atmospheric communication channel for guiding the external atmosphere into the interior of the ink cartridge, which is located on the atmospheric communication channel and only A gas-liquid separation membrane that allows air to pass through, a liquid guide channel that guides the ink in the ink storage chamber to the ink supply port, and a differential pressure valve located in the liquid guide channel to control the negative pressure of the ink cartridge to stably supply ink to the ink supply port. [0003] In addition, ink cartridges are used as consumables for printers, and most of them are discarded after us...
