Problems solved by technology

[0006] The "negative pressure ink filling" method does not need to apply a large positive pressure to achieve the purpose of filling ink in the ink cartridge to be filled. In practice, the ink filling device first needs to use the air pump 4 to draw air, and then the air pump The gas in the device 4 is injected into the storage box 1, and the ink in the storage box 1 is pressed into the pipette 2 by the gas pressure entering the storage box 1, and then enters the ink cartridge 7 to be filled. This operation process is not only cumbersome, but also It is difficult for the operator to control the amount of ink injected into the ink cartridge 7 to be filled. The amount of ink injected in the ink cartridge 7 to be filled may exceed a predetermined value, and then ink dripping occurs in the ink cartridge after filling; more importantly, , when using this method to fill ink, the ink outlet is located above the ink injection direction, so the space near the ink outlet of the ink cartridge 7 to be filled may not be filled with ink, when the filled ink cartridge is placed in the inkjet imaging device When in use, there will be a defect that the ink supply is not timely at the ink outlet, and it is necessary to improve the existing ink filling method

Embodiment 1

[0040] Figure 1A It is an exploded schematic diagram of the ink cartridge involved in the present invention; Figure 1B This is a perspective view of the ink cartridge according to the present invention when viewed from below.

[0041] The ink cartridge 100 includes a bottom case 20 and a surface cover 10 that are combined with each other. The ink is contained in the bottom case 20. For the convenience of description, the length direction of the ink cartridge 100 is defined as the front-rear direction, the width direction is the left-right direction, the height direction is the up-down direction, and the bottom direction is defined. The case 20 includes a front side panel 21 located at the front, a rear side panel 23 located at the rear, and a lower side panel 25 located between the front side panel 21 and the rear side panel 23 , and the face cover 10 is combined with the upper surface 24 of the bottom case 20 The bottom case 20 is formed with a cavity 28 for accommodating i...

Embodiment 2

[0065] Figure 5 It is a perspective view of the ink cartridge filling device according to the second embodiment of the present invention after the ink cartridge is installed; Image 6 It is an exploded schematic diagram of some components of the ink cartridge filling device involved in the second embodiment of the present invention.

[0066] This embodiment is a further improvement to the above-mentioned embodiment, and improves the operational convenience of the ink cartridge filling device. The following focuses on the differences of this embodiment.

[0067] like Figure 5 As shown, the ink cartridge filling device 200 further includes a fixing base 90 and a force applying component connected with the fixing base 90 , at least the movable portion 73 is fixedly installed in the installation groove 91 of the fixing base 90 , and the force applying component includes a force applying component connected with the operating portion 734 . The connecting part 92 , the force app...

Abstract

The invention relates to an ink cartridge filling device and a filling method. The filling device is used to inject ink into an ink cartridge to be filled. The to-be-filled ink cartridge includes a cavity for accommodating ink and an ink outlet communicated with the cavity; the filling device includes a replenishing box and an operating assembly. , a sealing component and a pipette, the supplementary box contains supplementary ink, the sealing component is used for sealing between the to-be-filled ink cartridge and the supplementary box and between the to-be-filled ink cartridge and the operation component, and the pipette is used to communicate the supplementary box and the to-be-filled box Ink cartridge; one end of the operating assembly is communicated with the ink outlet, and the other end is communicated with the replenishment box. When the operating assembly is operated, the end communicated with the ink outlet sucks the fluid in the ink cartridge to be filled, and at the same time, the other end communicated with the replenishment box One end forces the ink in the replenishment box to be injected into the cavity through a pipette. The filling device can ensure that the ink cartridge to be filled is just filled with a predetermined amount of ink, and the ink outlet is filled with ink, which can effectively prevent the ink supply from the ink outlet. timely.

Description

technical field [0001] The present invention relates to the field of inkjet imaging, and in particular, to an ink cartridge filling device and a filling method. The ink cartridge is detachably mounted to the inkjet imaging device. Background technique [0002] Regenerating the ink cartridge that has run out of ink is an existing preferred method for processing the empty ink cartridge shell, which enables the empty ink cartridge shell to be reused, which is beneficial to reducing environmental pollution. [0003] Filling the ink cartridge with ink is a key step in the ink cartridge regeneration process. A known ink filling method is called "positive pressure ink filling", that is, by applying positive pressure to the ink in the replenishment box, the ink is forced to be injected directly. The ink cartridge to be filled is simple and convenient, but because there is a certain amount of air in the ink cartridge to be filled, the air resistance in the ink cartridge to be filled ...
