[0002] An ink cartridge is a consumable for an inkjet imaging device. After the ink in the ink cartridge is consumed, the user needs to replace it with a new one, and the empty shell of the ink cartridge with consumed ink will be discarded, which will cause waste and environmental pollution. Considering environmental protection and cost reduction, the empty shell of the ink cartridge with consumed ink can be recycled to obtain a recycled ink cartridge.

[0003] In an existing ink cartridge, a differential pressure valve is provided on one side cover of the ink cartridge, and a sealing member for sealing the differential pressure valve is attached to the side of the ink cartridge where the differential pressure valve is provided, and there is a sealed space between the sealing member and the differential pressure valve; however, during transportation, affected by the external air pressure and temperature, the air pressure on both sides of the sealing member may be unbalanced, so the sealing member is prone to bulge or depression. Therefore, the original manufacturer usually sets through holes for balancing air pressure on the sealing member.

[0004] When recycling and manufacturing the above ink cartridge, due to the existence of the through holes, there may be liquid dirt in the space between the sealing member and the differential pressure valve. Therefore, in the recycled ink cartridge made from the empty shell of the ink cartridge with consumed ink, the liquid dirt formed by the original ink cartridge still exists, and during the transportation and sales of the recycled ink cartridge, the liquid dirt is prone to leakage, contaminating the user's hands or other components of the recycled ink cartridge.

[0019] Figure 3 It is a flowchart of the manufacturing method of the recycled ink cartridge related to the present utility model. Detailed implementation manners

[0020] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings.

[0021] The present utility model obtains a recycled ink cartridge 200 by recycling the original ink cartridge (abbreviated as "ink cartridge") 100 that has exhausted its ink. The basic structure of the ink cartridge 100 will be described below.

[0022] The ink cartridge 100 can be detachably installed to an imaging device, such as Figure 1 As shown, the ink cartridge 100 includes a cartridge body 10 and an ink outlet portion 20 that communicate with each other. An ink chamber 11 for containing ink is formed in the cartridge body 10. An ink outlet 21 is provided in the ink outlet portion 20. The ink in the ink chamber 11 is supplied to the outside of the ink cartridge 100 through the ink outlet 21. The ink cartridge 100 further includes a sixth sealing member 22 for sealing the ink outlet 21.

[0023] Taking the posture in which the ink cartridge 100 is installed to the imaging device as a reference, the cartridge body 10 has a top wall 12 and a bottom wall 13 in its height direction, a front side wall 14 and a rear side wall 15 in its front-rear direction, and a left side wall 16 and a right side wall 17 in its left-right direction. The top wall 12 and the bottom wall 13 are spaced apart, the front side wall 14 and the rear side wall 15 are spaced apart, the left side wall 16 and the right side wall 17 are spaced apart, and the top wall 12, the bottom wall 13, the front side wall 14, the rear side wall 15, the left side wall 16 and the right side wall 17 enclose to form the ink chamber 11; the height direction can be regarded as the up-down direction.

[0024] In some implementation manners, the ink outlet portion 20 and the cartridge body 10 are arranged in the up-down direction.

[0025] In some implementation manners, the ink outlet portion 20 and the cartridge body 10 are arranged in the front-rear direction.

[0026] In some implementation manners, the ink cartridge 100 is further provided with a handle 18 for easy handling, and the handle 18 is provided on the cartridge body 10.

[0027] As Figure 2As shown, the ink cartridge 100 includes an air guiding member 30 for communicating the ink chamber 11 with the atmosphere. The air guiding member 30 is disposed on the cartridge body 10. The air guiding member 30 at least includes a first communication hole 31, a second communication hole 32, and a connecting groove 33 connecting the first communication hole 31 and the second communication hole 32. The first communication hole 31 is used to communicate the atmosphere with the connecting groove 33, and the second communication hole 32 is used to communicate the ink chamber 11 with the connecting groove 33. The first communication hole 31, the second communication hole 32, and the connecting groove 33 form at least a part of the flow path for the atmosphere to flow into the ink chamber 11. It should be noted that the air guiding member 30 further includes an air guiding structure not shown in part of the figure. Optionally, the first communication hole 31 can be communicated with the connecting groove 33 through other conductor structures (not shown in the figure).

[0028] The ink cartridge 100 further includes a first sealing member 34 for sealing the first communication hole 31. Before the ink cartridge 100 is used, the first sealing member 34 needs to be removed / ripped off. In some embodiments, the first sealing member 34 is fixed to the cartridge body 10 by welding or bonding.

[0029] The ink cartridge 100 further includes a first covering member 35, which is configured to allow the atmosphere to pass through while preventing liquid from passing through. Specifically, the atmosphere can pass through the first covering member 35, enabling the ink chamber 11 to communicate with the atmosphere. Ink cannot pass from the ink chamber 11 through the first covering member 35 to reach the connecting groove 33 / the first communication hole 31, thus preventing ink leakage to the first communication hole 31. In some embodiments, the first covering member 35 has a smooth surface.

[0030] In some embodiments, the first communication hole 31, the second communication hole 32, and the connecting groove 33 are not disposed on the same side wall of the cartridge body 10.

[0031] The ink cartridge 100 further includes a communication channel 36 that communicates with the second communication hole 32 through an internal channel of the cartridge body 10. The atmosphere can also enter the ink chamber 11 from the communication channel 36.

[0032] In some embodiments, the communication channel 36 is disposed on one side of the left side wall 16 facing the ink chamber 11 or on one side of the right side wall 17 facing the ink chamber 11.

[0033] An adjusting member 40 for opening / closing the ink flow path is further disposed in the cartridge body 10. Specifically, the ink flow path in the ink cartridge 100 flows from the ink chamber 11 to the ink outlet 21. The adjusting member 40 is disposed in the cartridge body 10 and on the ink flow path, and is set to a closed state when the ink cartridge 100 does not supply ink to the imaging device. When a certain amount of ink is consumed from the cartridge body 10, a negative pressure is generated at one end of the adjusting member 40 close to the ink outlet 21, and then the adjusting member 40 changes to an open state under the action of this negative pressure.

[0034] Further, the regulating member 40 includes a chamber 41 and at least one support member 42. The chamber 41 forms a fluid communication with the ink chamber 11 through other conductor structures (not shown in the figure), and the support member 42 is used to prevent the regulating member 40 from being excessively deformed.

[0035] In some embodiments, the regulating member 40 is located on one of the left side wall 16 and the right side wall 17.

[0036] In some embodiments, the regulating member 40 is configured as a differential pressure valve.

[0037] In some embodiments, the regulating member 40 is provided with 4 support members 42, and the 4 support members 42 cause the first chamber 41 to form 4 sub-chambers.

[0038] The ink cartridge 100 further includes a second sealing member 50 for sealing the second communication hole 32, the connection groove 33, the communication channel 36, and the regulating member 40. With this arrangement, ink will not leak to the outside of the ink cartridge 100; a third communication hole 51 is further provided on the second sealing member 50, and the third communication hole 51 is used to balance the internal and external air pressures of the cartridge body 10 during transportation and prevent the ink cartridge from deforming.

[0039] In some embodiments, in the left-right direction, at least a part of the third communication hole 51 coincides with the regulating member 40. Specifically, at least a part of the third communication hole 51 coincides with the first chamber 41 or the sub-chambers of the first chamber, so that the air permeability effect of the third communication hole 51 is better.

[0040] The regenerated ink cartridge 200 provided by the present utility model is an ink cartridge regenerated and manufactured using the above-mentioned ink cartridge 100. In the regenerated ink cartridge 200, the components identical to those of the ink cartridge 100 are numbered the same. Hereinafter, an example will be given in which the air guiding member 30, the communication channel 36, and the regulating member 40 are all provided on the same side wall of the cartridge body 10.

[0041] During the manufacturing process of the regenerated ink cartridge 200, a fourth communication hole 61 needs to be provided on the second sealing member 50 of the ink cartridge 100. A gas flow is formed between the fourth communication hole 61 and the first cover member 35. The fourth communication hole 61 can increase the amount of gas entering the second communication hole 32, and has a high air permeability efficiency, which is convenient for making the filling process proceed faster during the process of filling ink into the ink chamber 11; the regenerated ink cartridge 200 further includes a fifth communication hole 62, and the fifth communication hole 62 is formed on the second sealing member 50 and is used to allow the communication channel 36 to be opened / exposed. During the manufacturing process, the ink filling device passes through the fifth communication hole 62, and the ink is directly filled into the ink chamber 11 through the communication channel 36.

[0042] In some embodiments, the fourth communication hole 61 is provided as an opening formed simultaneously in the second seal 50 and the first cover 35. The second seal 50 and the first cover 35 are opened simultaneously, so that the air guiding effect of the second communication hole 32 is better.

[0043] In some embodiments, the fifth communication hole 62 is provided as an opening formed by melting on one side wall of the second seal 50 and the ink cartridge 100.

[0044] The recycled ink cartridge 200 further includes a third seal 63, a fourth seal 64, a fifth seal 65 and a second cover 66. The third seal 63 is used to seal the third communication hole 51, the fourth seal 64 is used to seal the fourth communication hole 61, and the fifth seal 65 is used to seal the fifth communication hole 62. A brand-new first seal 34 is also required for the recycled ink cartridge to seal the first communication hole 31, so as to ensure good sealing performance of the recycled ink cartridge 200; the second cover 66 is used to cover / wrap the third seal 63, the fourth seal 64, the fifth seal 65 and the second seal 50, so that the recycled ink cartridge 200 is cleaner and more beautiful.

[0045] In some embodiments, since it is relatively difficult to cover the smooth surface of the second seal 50 with a plastic film, the fourth seal 64 and the third seal 63 are respectively fixed to the second seal 50 / the cartridge body 10 by means of glue sealing.

[0046] In some embodiments, since the fifth communication hole 62 is an opening formed by melting, the fifth seal 65 is fixed to the second seal 50 / the cartridge body 10 by means of welding.

[0047] In some embodiments, during the manufacturing process, an expansion member can also be placed in the first communication hole 31 to make the first communication hole 31 larger and improve the air permeability efficiency. For example, the expansion member is a sponge.

[0048] As Figure 3 shown, the manufacturing method of the recycled ink cartridge 200 in the present invention is as follows:

[0049] Cleaning the ink cartridge 100 and the first airtightness detection: First, suck out the ink remaining in the ink chamber 11 from the ink outlet 21. In this step, the atmosphere enters the cartridge body 10 through the first communication hole 31; then, an opening is formed in the second seal 50 and the first cover 35 to form the fourth communication hole 61, and the fourth communication hole 61 is temporarily sealed. The airtightness is detected by filling gas into the cartridge body 10 from the first communication hole 31 and detecting the air pressure in the cartridge body 10. Subsequently, the temporary seal of the fourth communication hole 61 is released;

[0050] First cleaning: Pour clear water into the first communication hole 31 and discharge it from the ink outlet 21. After that, pour the cleaning agent into the first communication hole 31, mill the ink outlet film, and leave it for half a month.

[0051] Second cleaning: Draw out the waste cleaning agent through the ink outlet 21. After that, repeatedly rinse with clear water and pump water.

[0052] Second airtightness detection and sealing: First, expand the first communication hole 31, then fill the expansion part into the first communication hole 31, temporarily seal the fourth communication hole 61, and detect the airtightness of the cartridge body 10 by filling gas into the cartridge body 10 from the first communication hole 31 and detecting the air pressure inside the cartridge body 10. This process can also further ensure that there is no liquid in the ink chamber 11. After that, seal the third communication hole 51 with the third seal 63 and seal the fourth communication hole 61 with the fourth seal 64. If the airtightness is unqualified, it is necessary to re-seal and detect.

[0053] Ink filling and sealing: The ink filling device directly fills ink into the ink chamber 11 through the fifth communication hole 62 via the communication channel 36. After filling, seal the fifth communication hole 62 with the fifth seal 65.

[0054] Seal the ink outlet 21: Seal the ink outlet 21 with the sixth seal 22.

[0055] Third airtightness detection and sealing of the seal, detect the airtightness of the cartridge body 10 by filling gas into the cartridge body 10 from the first communication hole 31 and detecting the air pressure inside the cartridge body 10. After the airtightness is qualified, seal the first communication hole 31 with a new first seal 34. If the airtightness is unqualified, re-seal and detect.

[0056] Wrapping / covering: Finally, wrap the third seal 63, the fourth seal 64, the fifth seal 65, and the second seal 50 with the second covering member 66.

[0057] In the above method, when detecting the airtightness by filling gas into the cartridge body 10 from the first communication hole 31 and detecting the air pressure inside the cartridge body 10, the pressure of the ink cartridge 100 can also be detected. If it reaches the set standard, proceed to the next step. If it does not reach the set standard, it is necessary to re-seal and detect.

[0058] [Beneficial effects]
