FIGS. 2A and 2B are schematic views showing the internal structure of the ink cartridge according to the present invention after its regeneration; fig. 3 is a sectional view taken along a plane passing through the center line of the ink outlet portion of the ink cartridge according to the present invention and parallel to the mounting direction of the ink cartridge.
As shown in the figure, the handle 4 and the chip mounting portion 5 are located on the same side surface (front side) of the case 3, and the ink discharging portion 6 is provided on the other side surface (lower side); the cartridge body 3 further includes an air passage 33 provided therein, the air passage 33 being capable of communicating the ink chamber 30 with the external atmosphere, and referring to fig. 1, 2A and 2B, the lower side of the cartridge body 3 is further provided with an air inlet chamber 32, an air inlet 33a of the air passage 33 is provided in the air inlet chamber 32, the air inlet chamber 32 is communicated with a first intermediate port 33c located at the upper side of the ink chamber 30 through a first flow passage 33B provided in the cartridge body 3, the air guide chamber 34 is communicated with a first intermediate port 33c and a second intermediate port 33d, the second intermediate port 33d is communicated with an air outlet 33f through a second flow passage 33e provided in the cartridge body 3, the air outlet 33f is directly communicated with the ink chamber 30, and the external atmosphere is capable of entering the ink chamber 30 through the air passage 33 after the sealing member 2 covering the air inlet chamber 32 is unsealed.
The check valve assembly 7 includes a frame 71 provided in the cartridge body 3, a check valve (not shown) provided in the frame, and an ink inlet 72 and an ink outlet 73 provided in the frame, the check valve assembly 7 communicating with the ink outlet portion 6 through the ink outlet passage 37 isolated from the ink chamber 30, and as described above, the ink in the ink chamber 30 is controllably supplied to the ink outlet portion 6 through the check valve assembly 7.
As can be seen from the above description, in the existing ink cartridge, before being discharged, the ink needs to pass through the check valve assembly 7, in the empty ink cartridge/the ink cartridge before regeneration, the inevitable residual ink exists in the check valve assembly 7 and cannot be discharged, and particularly, the ink in the check valve is more difficult to be discharged, and the residual ink which is not discharged will harden and agglomerate along with the long-term placement of the empty ink cartridge/the ink cartridge before regeneration, so that the empty ink cartridge/the ink cartridge before regeneration cannot be cleaned in the cleaning step of starting regeneration, when the end user uses the regenerated ink cartridge, the agglomerate may enter the ink outlet portion 6 along with new ink, so that the ink outlet portion 6/the ink suction needle is blocked, and the imaging quality is finally affected.
Therefore, the invention provides a regeneration method, in which at least the one-way valve in the one-way valve assembly 7 is shielded, so that the ink in the regeneration ink box can not flow through the one-way valve assembly 7 or the one-way valve in the one-way valve assembly, thereby effectively preventing the problem that the ink outlet part 6/the ink sucking needle is blocked because the lumps in the one-way valve are mixed with new ink.
In the embodiment of the present invention, the one-way valve may be shielded by cutting or blocking, for example, the one-way valve assembly 7 may be directly cut off or the one-way valve may be integrally cut off to communicate the ink chamber 30 with the ink outlet channel 37, or at least one of the ink inlet 72 and the ink outlet 73 of the one-way valve assembly 7 may be blocked, and the communication port 36 may be formed in the ink chamber 30 to directly communicate the ink chamber 30 with the ink outlet channel 37, at which time, the ink does not flow through the one-way valve assembly 7 any more.
When the mode of cutting off the check valve assembly 7 is adopted, the originally occupied space of the check valve assembly 7 can be vacated, at the moment, the volume of the ink cavity 30 is increased, and the ink box 30 can contain more ink; when the mode of cutting off the one-way valve is adopted, the ink in the ink cavity 30 can still enter the frame body 71 of the one-way valve component and then is supplied to the middle ink outlet part 6 through the ink outlet channel 37, the space occupied by the one-way valve is utilized originally, and the volume of the ink cavity 30 is also increased; when it is adopted to block at least one of the ink inlet 72 and the ink outlet 73, it is common to install a filler such as a filler plug, a rubber block or the like in the ink inlet 72 and/or the ink outlet 73, or glue is injected into the ink inlet 72 and/or the ink outlet 73, or a sealing member is welded/bonded around the ink inlet 72/the ink outlet 73, or by deforming the cartridge around the ink inlet 72 and/or outlet 73 by means of ironing, in a manner of closing/blocking the ink inlet 72 and/or the ink outlet 73, etc., at this time, the ink does not flow through the check valve assembly 7, and particularly, when both the ink inlet 72 and the ink outlet 73 are blocked, the ink does not enter the frame 71 of the check valve assembly at all, the lumps in the check valve assembly 7 do not reach the ink outlet portion 6/ink suction needle with the flow of ink.
As shown in fig. 2B, the communication port 36 is opened in a rib forming the ink outlet passage 37, and the ink in the ink chamber 30 flows first to the ink outlet passage 37 in a direction d1, and then flows to the ink outlet portion 6 in the ink outlet passage 37 in a direction d2, the direction d1 intersecting the direction d2, preferably, perpendicular to each other, that is, the ink in the ink chamber 30 does not flow directly to the ink outlet portion 6, and thus, the pressure of the ink in the ink chamber 30 to the ink outlet portion 6 can be reduced.
It is to be understood that the communication port 36 may be disposed at other positions in communication with the ink outlet passage 37, for example, when the amount of ink in the ink chamber 30 is relatively small when the regeneration ink cartridge has a small capacity, the communication port 36 may be disposed at a position closer to the ink outlet portion 6, and when the amount of ink in the ink chamber 30 is relatively large when the regeneration ink cartridge has a large capacity, the communication port 36 may be disposed at a position farther from the ink outlet portion 6.
As is apparent from the above description, the ink cartridge recycling method provided by the present invention includes the steps of:
a step of providing the empty cartridge/the cartridge before regeneration, in which a check valve assembly 7 is provided;
the step of shielding the one-way valve assembly 7 so that the ink in the ink chamber 30 no longer flows through at least the one-way valve;
a step of opening a communication port 36, the communication port 36 directly communicating the ink chamber 30 and the ink outlet passage 37/ink outlet portion 6;
a cleaning step, cleaning the empty ink box/the regeneration ink box;
a step of installing a negative pressure generating member for controlling the flow rate and the flow velocity of the ink flowing out from the ink outlet portion 6 by controlling the flow rate and the flow velocity of the air flowing into the ink chamber 30 during the operation of the regeneration cartridge;
a step of refilling ink into the ink chamber 30;
and sealing the ink box refilled with the ink to form a regenerated ink box.
In the step of shielding the check valve assembly 7, the steps can be implemented by cutting or blocking, and the like, which is specifically described above and will not be described herein again; further, the above regeneration steps do not constitute a limitation on the order of the steps of the regeneration method according to the present invention, and in actual production, the above steps do not need to be strictly followed, and the above steps may be adjusted according to production conditions, for example, the step of the shielding check valve assembly 7 and the cleaning step may be interchanged, and in this case, the cleaned cartridge may make the sealing member and the cartridge more firmly combined in a manner of installing the sealing member around the ink inlet 72/the ink outlet 73 by welding/bonding or the like; the cleaning step and the step of opening the communication port 36, and the step of opening the communication port 36 and the shielding check valve assembly 7 may be interchanged.
Further, when the gas flow path 33 in the empty ink cartridge is provided on the surface of the cartridge body 3, or one side of the cartridge body 3 is open, before the step of refilling ink, a step of sealing the gas flow path 33 and the open with a sealing member is further included; accordingly, before the cleaning step, a step of removing the sealing member for sealing the gas flow path 33 and the opening is further included.
By using the regeneration method, the empty ink box/the ink box before regeneration can be reused, which is beneficial to reducing environmental pollution, and meanwhile, the ink outlet part 6 of the regenerated ink box can not be blocked by the agglomeration in the check valve component 7, so that the imaging quality is improved.
