Problems solved by technology

Before the ink cartridge products obtained under this production process are used for printing, there will always be more air remaining in the ink storage cavity of the ink cartridge, and because the ink outlet, air guide port and ink filling port of the ink cartridge are all in a sealed state, so that After the vibration, bumps, and shaking caused by the transportation process, the air remaining in the ink storage chamber of the ink cartridge will enter the detection chamber, and even enter the ink pipeline in front of the ink outlet, causing the buoy in the detection chamber to lose buoyancy. , causing the ink cartridge to lose the function of detecting the ink capacity in its internal ink storage chamber
In the state of vibration or severe temperature change, air resistance may be formed on the ink outlet, resulting in no ink printing or line breakage.

Embodiment 1

[0027] In order to facilitate those skilled in the art to better understand the technical essence and essence of the present invention, the structure of an existing ink cartridge processed by the exhaust method of the present invention will be firstly introduced below in conjunction with the accompanying drawings. Throughout the drawings, the same reference numerals will be used to refer to the same components, features or structures. The specific structures or components targeted in the introduction of the embodiments are only used as reference examples for those skilled in the art to understand the exhaust method of the present invention, and those skilled in the art can also design no more than the present invention under the inspiration of this technical solution. Various equivalent or similar technical configurations of the technical scope and essence of the exhaust method. Therefore, it is inappropriate to use this exemplary description to limit the scope of protection c...

Embodiment 2

[0040] For the ink cartridge structure of Embodiment 1, its upstream link can also be adopted as that of Embodiment 1, and the last link of air extraction, pressure maintenance and pressure relief is slightly different from the technological process of Embodiment 1 to discharge the air in the ink cartridge, see image 3 . When the second embodiment is used to process the ink cartridge, the effects of the gas remaining in the detection chamber 9 and the ink outlet 5 are basically the same as those of the first embodiment. In the exhaust method of embodiment two, its pumping and pressure maintaining steps are as follows:

[0041] Place the port where the air guide port 4 communicates with the ink storage chamber 10 at the highest position in the vertical direction of the ink storage chamber 10, insert the air suction needle tube 23 into the air guide port 4 to communicate with the ink storage chamber 10, and extract the gas in the ink storage chamber 10 to Any specific value in...

Abstract

The invention relates to an inkjet printer used ink box exhausting method. The method comprises the following steps in sequence: firstly an ink inlet is sealed by elastic soft silica gel, an ink outlet is sealed by a one-way sealing valve, and an air guiding opening is remained in unblocked state; secondly the position of a testing cavity is remained at the lowest part along the plumb direction of the ink box; thirdly an ink conveying needle tube is inserted into an ink storage cavity through the elastic soft silicone along the ink inlet, the ink conveying needle tub is pulled out after the ink is injected for the full condition basically, and then the air guiding opening is sealed; fourthly, the ink inlet is maintained to be positioned at the highest part of the ink storage cavity along the direction of the plumb, an exhausting needle tube is inserted into the ink storage cavity through the elastic soft silicone along the ink inlet, the gas in the ink storage cavity is pumped, and anink box product can be obtained after pressure relief. The ink outlet and the testing cavity of the ink box processed through the method can achieve that the gas residual volume of the ink is extremely low udder storage, transportation, printing and other temperature variation environment.

Description

technical field [0001] The invention relates to an exhaust method for ink cartridges used in inkjet printers. This method is especially suitable for ink cartridges with the following characteristics: the inner chamber is filled with ink that is close to the full cavity or the design capacity, and the ink outlet is in a sealed state before receiving the ink supply needle of the inkjet printer, and the inner chamber is filled with ink. There is a detection chamber communicated with the ink outlet and provided with a buoy therein for detecting the ink capacity inside the ink cartridge. The recording head compatible with this ink cartridge is set on the inkjet printer carriage, and the ink cartridge as the ink containing device is detachably assembled on the inkjet printer carriage, and passes through the ink supply needle and the corresponding ink flow path. It is in communication with the nozzle on the recording head. Background technique [0002] For inkjet printers, the pr...
