Preferably, at least the side 621 of the second supporting plate 62 facing the first space S1 is a curved surface along the front-back direction of the ink cartridge C0, so as to adapt to the shape of fingers and improve the user experience of the operator.
[ method of modifying ink cartridges ]
The remanufacturing method of the ink cartridge C0 is described below with reference to fig. 2A and 2B. FIG. 2A is a perspective view of a small capacity type ink cartridge according to the present invention with a portion cut away; fig. 2B is a perspective view of a modified small-capacity type ink cartridge according to the present invention.
The method for expanding the capacity of the small-capacity ink box C0 is to install an external body C2 (described below) on the existing ink box C0 and communicate the existing ink box C0 cavity with the external body C2 cavity, so that air entering the existing ink box C0 cavity can be exchanged with ink in the external body C2 cavity, and the ink in the external body C2 cavity is supplemented into the existing ink box C0 cavity, thereby achieving the purpose of expanding the capacity of the existing ink box C0 cavity. The existing ink cartridge includes the ink cartridge C0 obtained in a recovery manner and having been depleted of ink, and also includes a new ink cartridge C1 obtained in an injection molding manner.
Specifically, the conventional ink cartridge C0/C1 is provided with a coupling portion, an air flow outlet 43, and an ink flow inlet 44, the external unit C2 is provided with a coupled portion, an air flow inlet tube 88, and an ink flow outlet 89, the coupling of the coupling portion and the coupled portion allows the coupling of the air flow outlet 43 and the air flow inlet tube 88, and the coupling of the ink flow inlet 44 and the ink flow outlet 89, and the conventional ink cartridge C0/C1 and the external unit C2 are coupled to a modified ink cartridge C described below.
As shown in fig. 2A, the closing plate 41 is cut away so that the first space S1 forms an opening K in the front-rear direction, and the arc surface 621 faces the opening K, and further, the arc portion 42 is cut away so that the opening K is larger, which is more beneficial to the combination of the external body C2; further, it is also possible to cut out a part of the upper rib 61 or a part of the lower rib 31 so that the upper rib 61 and the lower rib 31 have different lengths in the front-rear direction, and advantageous effects thereof will be described later.
Meanwhile, the ink cartridge C1 has the left support plate 32a and the right support plate 32b cut away, and as shown in the drawing, the upper rib 61 and the lower rib 31 are supported by the second support plate 62, and although the closing plate 41 and the arc portion 42 located at the rear are cut away, the opening K is formed between the top plate 60 and the upper side plate 30, and the top plate 60 located near the opening K is no longer supported, however, the second support plate 62 functions to support the top plate 60, and thus, the strength of the top plate 60 and the ink cartridge C1 can be ensured.
As shown in fig. 2B, at least one of the gas flow-out port 43 and the ink flow-in port 44 is opened on the side where the ink outlet 11 is not provided, that is, neither the gas flow-out port 43 nor the ink flow-in port 44 is provided on the same side plate as the ink outlet 11, and preferably, the gas flow-out port 43 and the ink flow-in port 44 are provided on the same side plate; more preferably, the air outlet 43 and the ink inlet 44 are provided on the rear side plate 40, and the air outlet 43 is located between the opening K and the ink inlet 44 in the vertical direction, so that the opening direction of the opening K is the same as the opening direction of the air outlet 43 and the ink inlet 44.
The gas outlet 43 and the ink inlet 44 are both arranged in a stepped shape, that is, a step surface 431 is formed between the gas outlet 43 and the rear side plate 40, and a step surface 441 is also formed between the ink inlet 44 and the rear side plate 40, wherein the gas outlet 43 is used for enabling the air entering the cavity of the ink cartridge C1 through the air inlet 12 to flow out to the external body C2, and the ink inlet 44 is used for enabling the ink in the external body C2 to flow into the cavity of the ink cartridge C1 after the air enters the cavity of the external body C2 from the cavity of the ink cartridge C1.
[ external component ]
Fig. 3A and 3B are perspective views of the external body according to the present invention.
The external unit C2 contains ink for combining with the modified ink cartridge C1 to expand the cavity capacity of the ink cartridge C1. as shown in the figure, the external unit C2 includes an external unit 80 and a combined part 90 combined with the external unit 80, the ink is contained in the external unit 80, and the combined part 90 is used for combining with a combined part arranged on the ink cartridge C1.
Like the ink cartridge C0 and the ink cartridge C1, the exterior body C2 also has the front, rear, upper, lower, left, and right, and the coupled portion 90 projects forward from the front panel 81 of the exterior member 80. The exterior member 80 has the same size in the up-down direction as the ink cartridge C0 and the ink cartridge C1, and thus the ink cartridge C after expansion is substantially flush in the up-down direction (as shown in fig. 5).
The exterior member 80 includes a front panel 81, a rear panel 82, an upper panel 83, a lower panel 84, a right panel 85 and a cover member 86, wherein the front panel 81, the rear panel 82, the upper panel 83, the lower panel 84 and the right panel 85 enclose an ink storage space S4 with one side open, and the cover member 86 covers the opening, so that the ink storage space S4 can be sealed; preferably, the cover 86 is made of a transparent material, for example, the cover 86 is a transparent PP film, so that an operator can observe whether ink is still in the ink storage space S4 from the outside of the cover 86.
As described above, the coupled portion 90 protrudes forward from the front panel 81, the exterior member 80 further includes the gas inflow tube 88 and the ink outflow tube 89 provided on the front panel 81, the gas inflow tube 88 is for coupling with the gas outflow port 43 provided on the ink cartridge C1, the ink outflow tube 89 is for coupling with the ink inflow port 44 provided on the ink cartridge C1, and the gas inflow tube 88 and the ink outflow tube 89 protrude forward from the front panel 81. Also, the gas inflow tube 88 is located between the ink outflow tube 89 and the joined portion 90 in the up-down direction.
Preferably, the ink inlet port 44 and the ink outlet port 89 are disposed as close as possible to the lower side plate 50 of the ink cartridge C1 and the lower surface plate 84 of the exterior member 80, respectively, however, in consideration of the actual shape of the ink cartridge C1, there is always a certain distance between the ink inlet port 44 and the lower side plate 50 in the up-down direction, and therefore the ink outlet port 89 is also always a certain distance from the lower surface plate 84. As shown in fig. 3A, the external member 80 further includes a partition plate G, which partitions the empty chamber S3 in the ink storage space S4, and the ink outflow tube 89 is disposed adjacent to the partition plate G, so as to ensure that all the ink stored in the ink storage space S4 is consumed without waste.
Of course, the partition plate G is not essential, and for example, the size of the external member 80 is smaller than that of the ink cartridge C1 in the up-down direction, and the difference in size between the two is the size of the empty chamber S3 in the up-down direction; further, the external member 80 further includes a flow guide member 87 provided in the ink storage space S4, and preferably, the flow guide member 87 is a plate-shaped member protruding from the right panel 85 toward the ink storage space S4, and the flow guide member (flow guide plate) 87 is inclined toward the ink outflow tube 89 and is not in contact with other portions of the external member 80, so that the flow efficiency of the ink in the ink storage space S4 is effectively improved, and the resistance from the flow guide member 87 to the flow of the air and the ink in the ink storage space S4 can be greatly reduced.
As shown in fig. 3B, the joined portion 90 includes a first joining rod 91 and a second joining rod 92 extending forward from the front panel 81, the first joining rod 91 and the second joining rod 92 being parallel to each other and forming a clamping space 93; when the coupled portion 90 is coupled with the ink cartridge C1 in the front-rear direction, at least one of the upper rib 61 and the lower rib 31 enters the clamping space 93, the first coupling lever 91 and the second coupling lever 92 are restricted by the top plate 60 and the upper side plate 30 in the up-down direction, the first coupling lever 91 and the second coupling lever 92 are restricted by at least one of the upper rib 61 and the lower rib 31 in the left-right direction, and finally, the position of the exterior body C2 with respect to the ink cartridge C1 is determined.
As for the lengths of the upper rib 61 and the lower rib 31 in the front-rear direction, as described above, the lengths of the two are not uniform, i.e., the upper rib 61 is longer than the lower rib 31 in the front-rear direction, or the lower rib 31 is longer than the upper rib 61, whichever is longer, and the shorter rib can provide a space for the coupled portion 90 to swing in the left-right direction when the coupled portion 90 is coupled with the ink cartridge C1, thereby making the coupling of the external body C2 with the ink cartridge C1 more efficient.
As described above, the ink cartridge C1 needs to be provided with a joint portion capable of being joined to the joined portion 90, and particularly, in the embodiment of the present invention, the joint portion includes the top plate 60, the upper side plate 30, and at least one of the upper rib 61 and the lower rib 31, wherein the top plate 60 and the upper side plate 30 restrict the joined portion 90 in the up-down direction, and at least one of the upper rib 61 and the lower rib 31 restricts the joined portion 90 in the left-right direction, that is, when the exterior body C2 is joined to the ink cartridge C1 in the front-back direction, the joint portion includes a member capable of restricting the joined portion 90 in the up-down direction and the left-right direction; generally, the joint portion includes a member that spatially restricts the joined portion 90 in a direction perpendicular to a direction in which the external unit C2 and the ink cartridge C1 are joined.
Although the upper side plate 30 is a part forming the cavity of the ink cartridge C1, if only the structure of the joint is considered, the upper side plate 30 may be peeled off from the part forming the cavity of the ink cartridge C1, so that the joint can be described as: includes a top plate (upper member) 60 for restricting the coupled portion 90 in the upper direction, an upper side plate (lower member) 30 for restricting the coupled portion 90 in the lower direction, and at least one of an upper rib 61 and a lower rib 31 for restricting the coupled portion 90 in the left-right direction, wherein the upper rib 61 and the lower rib 31 protrude in the upper-lower direction from the upper member 60 and the lower member 30, respectively; in connection with the embodiment of the present invention, the joint portion is provided above the cavity of the ink cartridge C1, however, it is also possible to provide a joint portion at other portions of the ink cartridge C1, for example, a joint portion is provided at the left, right, lower, etc. of the ink cartridge C1, as long as the joint with the joined portion 90 is achieved.
As described above, in the modified ink cartridge C1, the second support plate 62 remains between the upper rib 61 and the lower rib 31, and when the joining portion is joined to the joined portion 90, the second support plate 62 enters the nip space 93 along with the upper rib 61 and the lower rib 31. In order to further enhance the strength of the expanded ink cartridge C, as shown in fig. 3A and 3B, a support table 94 is further provided in the nip space 93, and when the joining portion is joined to the joined portion 90, at least a part of the upper rib 61 and the lower rib 31 is supported by the support table 94, and the upper rib 61, particularly the top plate 60, is restrained from shaking in the up-down direction by the support table 94.
The support stand 94 may be formed to be smaller than the clamping space 93 in the up-down direction, and the support stand 94 may be formed to extend forward from the front panel 81, or may be formed only in the clamping space 93 without contacting the front panel 83, and when the support stand 94 is formed in the latter manner, the support stand 94 may be formed separately from the coupling rod, i.e., the support stand 94 is a separate member externally mounted to the clamping space 93, and in the front-rear direction, the clamping space 93 is formed to be partitioned into a front clamping part 93a and a rear clamping part 93b, preferably, in the direction in which the size of the front clamping part 93a and the size of the rear clamping part 93b are substantially the same as the size of the second space S2 and the size of the first space S1, respectively, in the up-down direction, the size of the support stand 94 is substantially the same as the size of the first space S1, and when the coupling part of the coupling rod 91 and the coupled part of the coupled rod 92 facing the front clamping part 93a is coupled to the coupled part 90 is opposed to the second space S2 The support stand 94 is opposite to the first space S1, and the support stand 94 substantially fills the first space S1.
More preferably, as shown in fig. 3B, the front end of the supporting platform 94 is further provided with a mating surface 941 that mates with the second supporting plate side 621, so that the combination of the combining portion and the combined portion 90 is tighter, and the entire ink cartridge C has better strength after expansion.
While the above has been described with the joint being provided on the ink cartridge C1 and the coupled part 90 being provided on the outer body C2, it is contemplated that the positions of the joint and the coupled part 90 may be interchanged, i.e., the joint is provided on the outer body C2 and the coupled part 90 is provided on the ink cartridge C1; regardless of whether the ink cartridge C1 is provided with the joint portion or the joined portion 90, it is preferable that neither the joint portion nor the joined portion 90 be provided on the side of the ink outlet 11.
[ combination of external body and modified ink cartridge ]
FIG. 4 is a schematic view showing a state where the modified small-capacity type ink cartridge is coupled to the external unit; fig. 5 is a perspective view of the modified small capacity type ink cartridge combined with an external unit.
Since the modified ink cartridge C1 is separately opened with the gas outlet 43 and the ink inlet 44, before the ink cartridge C1 is filled with ink, the gas outlet 43 and the ink inlet 44 are separately sealed, as shown in fig. 4, the ink cartridge C1 further includes a self-sealing member 70 for sealing the gas outlet 43 and the ink inlet 44, and the self-sealing member 70 is capable of automatically sealing without being subjected to an external force, and includes a sealing body 71 having an insertion port 73 and a flange 72 formed at one end of the sealing body 71, the sealing body 71 is engaged with the gas outlet 43, and the flange 72 is engaged with the step surface 431, and does not extend beyond the rear side plate 40 in the front-rear direction after the sealing member 70 is mounted. When the external unit C2 is coupled to the ink cartridge C1, the gas inlet tube 88 is inserted into the cavity of the ink cartridge C1 through the insertion port 73, thereby allowing gas communication between the cavity of the ink cartridge C1 and the cavity of the external unit 80.
Similarly, the ink inlet 44 is sealed by the self-sealing member 70, and the ink outlet tube 89 is inserted into the cavity of the ink cartridge C1 through the inlet 73, so that the ink (liquid) communication is established between the cavity of the ink cartridge C1 and the cavity of the exterior member 80. Since the self-sealing member 70 does not extend beyond the rear side plate 40, as shown in fig. 5, when the external body C2 is combined with the ink cartridge C1, the rear side plate 40 of the ink cartridge C1 can be tightly combined with the front panel 81 of the external member 80, thereby improving the appearance of the ink cartridge C after expansion.
Alternatively, the gas outflow port 43 and the ink inflow port 44 may be provided as a gas outflow port and the ink outflow port 89 may be provided as an ink inflow port in the ink cartridge C1, and correspondingly, the gas inflow port 88 and the ink outflow port may be provided as a gas inflow port and an ink outflow port in the external member 80, respectively.
[ replacement of external component ]
As described above, the external body C2 is combined with the modified ink cartridge C1 to form an expanded ink cartridge C, and then the expanded ink cartridge C can be filled with ink as the unmodified ink cartridge C0, and in the up-down direction, when the ink line in the ink cartridge C1 is higher than the gas outflow port 43, the ink in the ink cartridge C1 will be consumed first, when the ink line in the ink cartridge C1 is lower than the gas outflow port 43, the air entering the cavity of the ink cartridge C1 will enter the ink storage space S4 of the external member 80 through the gas outflow port 43, resulting in the increase of the air pressure in the ink storage space S4, and the ink in the ink storage space S4 will flow into the cavity of the ink cartridge C1 through the ink outflow port 89, so that the ink line in the cavity of the ink cartridge C1 is consistent with the gas outflow port 43, and the process is repeated until the ink in the external body C2 is consumed, and then the ink cartridge in the cavity of the ink cartridge C1 starts to be consumed; the ink amount in the chamber of the ink cartridge C1 is always maintained at a constant value, i.e., the ink line is at the same height as the gas outlet 43, until the ink in the external body C2 is consumed, so that even if the ink cartridge C is shaken during operation of the ink jet printer, the pressure change of the ink cartridge C1 to the print head is almost negligible, thereby ensuring stable printing quality.
The change in the amount of ink in the ink storage space S4 of the external member 80 can be observed at any time by the operator through the transparent cover member 86, and the ink outflow tube 89 is disposed in close proximity to the partition G, which results in complete consumption of the ink in the ink storage space S4. In the embodiment of the present invention, the external body C2 is replaceable, that is, the external body C2 and the ink cartridge C1 are detachably coupled, and when the operator observes that the ink in the ink storage space S4 is consumed, the external body C2 which has consumed the ink can be separated from the ink cartridge C1, and then a new external body C2 is replaced to be coupled with the ink cartridge C1.
The replacement process of the external body C2 is as follows:
first, the external body C2 and the ink cartridge C1, which have been exhausted, are separated from each other, and since the self-sealing member 70 has a self-sealing function, the self-sealing member 70 located at the air outlet 43 and the ink inlet 44 is automatically sealed after the air inlet tube 88 and the ink outlet tube 89 are disengaged from the air outlet 43 and the ink inlet 44, respectively, so that the ink in the ink cartridge C1 does not flow out.
Then, the front panel 81 where the gas inflow tube 88 and the ink outflow tube 89 of the prepared exterior body C2 are located is placed upward, the rear panel 40 where the gas outflow port 43 and the ink inflow port 44 of the ink cartridge C1 are located is placed downward, so that the gas outflow port 43 corresponds to the gas inflow tube 88, the ink inflow port 44 corresponds to the ink outflow tube 89, and at least one of the rib 61 and the rib 31 corresponds to the holding space 93, and finally the ink cartridge C1 is combined with the new exterior body C2.
By making the external unit C2 replaceable, an operator can expand the capacity of the ink cartridge C according to the type of the ink jet printer by combining the external unit C2 and the ink cartridge C1, that is, the capacity of the expanded ink cartridge C is not a fixed value, but can be changed arbitrarily according to the requirement.
In summary, the expansion method according to the present invention is applicable not only to the new ink cartridge C1 formed by injection molding but also to the existing ink cartridge C0 that has consumed ink, and only when the existing ink cartridge C0 that has consumed ink is used, the ink cartridge C0 is modified or regenerated into the ink cartridge C1 so that the joint or the joined portion 90 is formed in the ink cartridge C1, and the specific method is as follows:
preparing an external body C2 containing ink;
cutting off the closing plate 41, the arc part 42 and the first support plate 32 on the polygon body (the modified ink box) C0 to form a modified ink box C1;
an air outlet 43 and an ink inlet 44 are arranged on the rear side plate 40;
a part of the external body C2 (bonded portion 90) is inserted between the upper side plate 30 and the top plate 60 such that at least one of the upper rib 61 and the lower rib 31 is opposed to the external body C2, and the external body C2 is in gas communication and liquid communication with the polygonal body C1 through the gas flow outlet 43 and the ink flow inlet 44.
Wherein, cutting away first support plate 32 includes cutting away left support plate 32a located at the left side of the second support plate and right support plate 32b located at the right side of the second support plate, and finally, second support plate 62 is further provided between upper side plate 30 and top plate 60.
The external body C2 is detachably coupled to the polygonal body (modified ink cartridge) C1, and forms a gas communication and an ink (liquid) communication therebetween, thereby forming the volume-expanded ink cartridge C.
