Method for filling ink into inkjet ink box

Abstract

The invention relates to a method for filling ink into an inkjet ink box. The method comprises the step of forming a first connection channel for filling the ink and a second connection channel for reducing pressure on the ink box. When the ink is filled, a filling hole is not required to be formed, so that harm to the performance of the ink box can be avoided; the ink is filled simply; the air inlet performance of the air connection channels can be fully guaranteed; the ink can be accommodated as much as possible; and the printing effect of the filled ink box is fully guaranteed.

Description

technical field [0001] The invention relates to an ink injection method for an inkjet ink box. Background technique [0002] With the widespread use of inkjet printers, the consumption of ink cartridges has gradually increased. However, as ink cartridges are used as consumables, most of them are discarded after use, and these discarded ink cartridges include plastics, films, chips, etc. Most of the components cannot be degraded naturally, which will not only cause waste of resources, but also bring a burden to the environment. Obviously, if the empty and used ink cartridges are not recycled, the pollution to the environment will become more and more serious. For this reason, the preferred solution is to recycle the ink cartridge, refill the ink, and make it obtain secondary use value. [0003] The common way of filling ink is the way of negative pressure ink filling, mostly the negative pressure inside the ink cartridge is sucked from the ink outlet of the ink cartridge, a...

Problems solved by technology

However, in order to maintain the quality of the stored ink for a long time and prevent the ink from evaporating and causing its viscosity to increase, the air intake passage on the ink cartridge is often arranged tortuous and has a thinner diameter, so when the ink is injected into the ink cartridge from the air inlet When it is used, it is easy to leave part of the ink in the air intake channel, and when the residual ink becomes dry, it will affect the performance of the air intake channel

In addition, in order to ensure a stable ink supply during the printing process and to monitor the ink exhaustion in a timely manner, the existing ink cartridges are often equipped with relatively complicated negative pressure control mechanisms and ink volume detection mechanisms, such as differential pressure valves installed in the ink channels. , piezoelectric sensors, etc. For this reason, the position of the injection hole must be carefully selected, otherwise, if the position of the injection hole is not selected properly, it may damage the performance of the internal components of the ink cartridge, thereby affecting the printing quality of the ink cartridge, resulting in poor regeneration of the ink cartridge

[0004] In addition, for multi-cavity ink cartridges, if the position of the injection hole is improperly selected, it may cause some air to be trapped in the cavity during ink filling, which may easily cause printing disconnection or affect the performance of the ink volume detection mechanism. Detection performance

[0005] Moreover, if the ink cartridge is processed more complicatedly in order to inject ink, the processing cost is higher, even higher than the cost of manufacturing a new ink cartridge, then regeneration does not make much sense
