As shown in Figure 8, top ink accommodating chamber 370 is ink accommodating chambers of the upstream (position is by last) in the toner cartridge main body 10, forms in the face side of toner cartridge main body 10.This top ink accommodating chamber 370 is half ink housing regions that account for the ink accommodating chamber, forms in roughly half part up of toner cartridge main body 10.The ink discharge 371 that is communicated with ink path of navigation 380 is at depressed part 374 split sheds of the diapire of top ink accommodating chamber 370.This ink discharge 371 be positioned at than the rib 10a of the diapire that becomes top ink accommodating chamber 370 by under the position, even therefore the ink level in the top ink accommodating chamber 370 drops to diapire, this ink discharge outlet 371 also is positioned at the below of ink level this moment, therefore can continue stably to derive ink I.
As shown in Figure 9, ink path of navigation 380 is formed on the rear side of toner cartridge main body 10, and ink I is imported to the bottom ink accommodating chamber 390 of below from the top.
Bottom ink accommodating chamber 390 is ink accommodating chambers that ink I stored in the ink accommodating chamber 370 of top is imported into, as shown in Figure 8, be half the ink housing region that accounts for the ink accommodating chamber that forms in the face side of toner cartridge main body 10, form in roughly half part down of toner cartridge main body 10.Near the rib 10a of the diapire that becomes this bottom ink accommodating chamber 390, the connection stream split shed of the ink inflow entrance 391 that is communicated with ink path of navigation 380 below the diapire 395 that is configured in bottom ink accommodating chamber 390 is communicated with stream from the ink I of top ink accommodating chamber 370 via this and flows into.
Bottom ink accommodating chamber 390 is used up sensor by the ink discharge outlet 311 that runs through diapire 395 with the upstream side ink and is communicated with stream 400 connections.Use up sensor at the upstream side ink and be communicated with that dimensional topography becomes the labyrinth stream is arranged in the stream 400, before ink is used up, catch the bubble B etc. of inflow, make it can not flow to the downstream by this labyrinth stream.
Upstream one side ink is used up sensor and is communicated with stream 400 and uses up sensor via not shown through hole and downstream ink and is communicated with stream 410 and is communicated with, and uses up sensor connection stream 410 with ink I importing ink remaining amount sensor 31 via the downstream ink.
The ink I that is imported into ink remaining amount sensor 31 is imported the ink path of navigation 420 that forms in the back side of toner cartridge main body 10 side by the chambers (stream) in the ink remaining amount sensor 31 from the ink discharge outlet 312 as the outlet of chamber.Ink path of navigation 420 flows into 431 with the ink that is communicated with surge chamber 430 and is connected according to ink I is formed from the mode of ink remaining amount sensor 31 guiding oblique uppers.Thus, the ink that flows out from ink remaining amount sensor 31 is imported into surge chamber 430 via ink path of navigation 420.
The ink I that flows into differential valve 40 is directed to the downstream by differential valve 40, and is directed to outlet stream 450 via through hole 451.Outlet stream 450 is communicated with ink supply aperture 50, and ink I is supplied to the ink-jet recording apparatus side by the ink supply pin 240 that is inserted in the ink supply aperture 50.
In addition, under the situation of above-mentioned print cartridge 1, as shown in Figure 8,, except being formed with aforesaid ink accommodating chamber (top ink accommodating chamber 370, bottom ink accommodating chamber 390, surge chamber 430), air chamber (ink cuts and deposits chamber 340, is communicated with surge chamber 350), ink path of navigation (upstream side ink use up sensor is communicated with stream 400, the downstream ink is used up and is communicated with stream 410), also dividing and be formed with the not non-filled chamber 501 of filling ink I in the face side of toner cartridge main body 10.
The hatched area of the left surface face side that non-filled chamber 501 is toner cartridge main bodies 10, close is by top ink accommodating chamber 370 and bottom ink accommodating chamber 390 clampings.
And, be provided with the atmosphere opening hole of running through to rear side 502 in the upper left corner of the interior zone of this non-filled chamber 501, be communicated with extraneous gas by this atmosphere opening hole 502.
When print cartridge 1 being reduced pressure the encapsulation packing, this non-filled chamber 501 becomes the degas chamber of the pressure accumulation degassing with negative pressure.
Then, illustrate from atmosphere opening hole 100 to the ambient air flow path 150 of top ink accommodating chamber 370 with reference to Fig. 8～Figure 12.
When the ink I in the print cartridge 1 is consumed and when causing print cartridge 1 pressure inside to reduce, the atmosphere (air) suitable with the reduction of stored ink I can flow into the top ink accommodating chamber 370 from atmosphere opening hole 100.
The aperture 102 that is arranged on 100 inside, atmosphere opening hole is communicated with an end of the serpentine pathway 310 that forms in the back side of toner cartridge main body 10 side.Serpentine pathway 310 forms elongated sinuous path, thereby can prolong from atmosphere opening hole 100 to the distance of top ink accommodating chamber 370, suppresses the water evaporates in the ink.The other end of serpentine pathway 310 is connected with gas-liquid separation filter 70.
On the bottom surface of the 70a of gas-liquid separation chamber that constitutes gas-liquid separation filter 70, be formed with through hole 322, be communicated with space 320 in the face side formation of toner cartridge main body 10 via through hole 322.In gas-liquid separation filter 70, between the other end of through hole 322 and serpentine pathway 310, dispose gas-liquid separation membrane 71.Gas-liquid separation membrane 71 is formed by the net of scolding the fibrous material of oiliness to weave into high water repellency and height.
When the face side of toner cartridge main body 10 is observed, space 320 forms in the upper right side of top ink chamber.In space 320, through hole 321 is at the upper opening of through hole 322.Space 320 links stream 330 via this through hole 321 with the top of side formation overleaf and is communicated with.
Top links stream 330 and comprises: circuit portion 333, by the top side of print cartridge 1, the i.e. part of the top of the gravity direction under the state that print cartridge has been installed,, extend to the right along growing the limit from through hole 321 when when rear side is observed; And circuit portion 337, turning back near return portion 335 places minor face, by than circuit portion 333 upper face side by last print cartridge 1, and extends near the through hole 341 of formation through hole 321.In addition, through hole 341 and the ink that forms in face side cut and deposit chamber 340 and be communicated with.
Here, when observing this top binding stream 330 from rear side, the circuit portion 337 that extends to through hole 341 from return portion 335, be provided with the position 336 that forms through hole 341 and on the print cartridge thickness direction than position 336 recessed darker recess 332, and be formed with a plurality of ribs 331 that separate this recess 332.In addition, extend to the circuit portion 333 of return portion 335 than the depth as shallow that extends to the circuit portion 337 of through hole 341 from return portion 335 from through hole 321.
In this example, link stream 330 because the part in the top of gravity direction forms top, therefore ink I can not surpass that top links stream 330 and to atmosphere opening hole 100 side shiftings basically.In addition, top links stream 330 and has widely to the thickness of the degree that ink I flows backwards can taking place owing to capillarity etc., and owing to be formed with recess 332 in circuit portion 337, therefore can easily catch the ink I that refluence is come.
When from positive unilateral observation, ink cuts deposits the space that chamber 340 is rectangular shapes of forming of the top-right corner positions at toner cartridge main body 10.As shown in figure 12, when when face side is observed, through hole 341 cuts near the opening bight of the upper left inboard of depositing chamber 340 at ink.In addition, cut the bottom-right bight of a side at the moment of depositing chamber 340 at ink and be formed with the cut and notch 342 that forms of the part of rib 10a of interval action, via this notch 342 be communicated with surge chamber 350 connections.Here, ink cuts and deposits chamber 340 and be communicated with surge chamber 350 is the air chambers that enlarged the form of ambient air flow path 150 volume midway, form in such a way: even at ink I for a certain reason and under the situation about flowing backwards from top ink accommodating chamber 370, also can make ink I be deposited in ink and cut and deposit chamber 340 and be communicated with in the surge chamber 350, and ink I can not continued to atmosphere opening hole 100 side inflows.The back will illustrate that ink cuts the concrete effect of depositing chamber 340 and being communicated with surge chamber 350.
The through hole 372 of one end of thin communication paths 360 is via ambient air flow path 150 air flow that extraneous gas imports in the top ink accommodating chamber 370 to be exported.In addition, the through hole 351 of the other end of thin communication paths 360 be communicated with surge chamber 350 and be communicated with, be from being communicated with surge chamber 350 imports air flow inlet from extraneous gas to thin communication paths 360.
In above-mentioned thin communication paths 360, be arranged on as the through hole 372 of the air flow of one end outlet upstream top ink accommodating chamber 370 diapire 375 (with reference to Figure 10) near, and, be arranged on and the diapire 375 of top ink accommodating chamber 370 below at a distance of H1 as the through hole 351 of the air flow of other end inlet.
As Figure 10 (b) and shown in Figure 14, thin communication paths 360 forms the shape of approximate L word, and it comprises: from as the through hole 372 of air flow outlet first communication paths 361 near normal below extended distance H1; And from the lower end of this first communication paths 361 to horizontal direction extended distance L1 and second communication paths 362 that is communicated with through hole 351 as the air flow inlet.
The thin communication paths 360 that is formed approximate L word shape by first communication paths 361 and second communication paths 362 is that flowing path section forms than other communication paths thin communication paths of at least a portion partly that constitutes ambient air flow path 150, and the part that the meniscus by path will be contained in the ink I in the top ink accommodating chamber 370 remains in first communication paths 361 and second communication paths 362.
Because all parts of communication paths 360 are all thin to the degree that can form meniscus, even therefore when the air of ink accommodating chamber 370 inside, top because thereby variations in temperature etc. are former thereby expand or when shrinking the liquid that causes formation communication paths 360 in and moving, also can be at the formation of the somewhere in the communication paths 360 meniscus.
In addition, as get off the length H1 that sets aforesaid first communication paths 361 and the length L 1 of second communication paths 362: the suitable amount of quantity of ink that remains on the inside of thin communication paths 360 for the ink I that is contained in the top ink accommodating chamber 370 and atmosphere outside are completely cut off.
In the print cartridge 1 of as above explanation, ambient air flow path 150 by by the ink I that part kept that is arranged on its thin communication paths 360 midway by fluid-tight, therefore the moisture that is stored in the ink in the top ink accommodating chamber 370 can be from ambient air flow path 150 to external evaporation, thereby can prevent because the viscosity rising of the ink I that the evaporation of moisture causes.In addition, when the air pressure in the top ink accommodating chamber 370 descends owing to the consumption of the ink I in the top ink accommodating chamber 370, fluid-tight meeting in the thin communication paths 360 makes atmosphere outside become small bubble state and it is imported in the top ink accommodating chamber 370 by the ink that carries out fluid-tight, thereby make the air pressure in the top ink accommodating chamber 370 revert to atmospheric pressure, and when the air pressure in the top ink accommodating chamber 370 did not descend, atmosphere outside was not imported into.
That is,, therefore can suppress owing to ink I contacts the deterioration that causes ink I with ozone owing to will be restricted to necessary Min. via the atmosphere that ambient air flow path 150 flow in the ink accommodating chamber 370.
Therefore, can keep the quality of ink I stored in each ink accommodating chamber 370,390,430 steadily in the long term.
In addition, under the situation of above-mentioned print cartridge 1, in carrying out the thin communication paths 360 of fluid-tight, be arranged on as the through hole 372 of the air flow of an end inlet top ink accommodating chamber 370 diapire 375 near, be arranged on and the diapire 375 of top ink accommodating chamber 370 below as the through hole 351 of the air flow inlet of the other end at a distance of H1.
Therefore, for example when in factory etc., in toner cartridge main body 10, filling the ink I of ormal weight, can carry the ink I of aequum and keep this ink I to the part of thin communication paths 360 by the hydraulic pressure of the ink I in the top ink accommodating chamber 370 that acts on air flow outlet, thus can be easily in the fluid-tight of the formation midway portion of ambient air flow path 150.
In addition, under the situation of above-mentioned print cartridge 1, because the part of thin communication paths 360 forms the shape of approximate L word, therefore the meniscus that produces at the bend of approximate L word shape has been given play to the confining force that limit ink I moves (refluence) to the ink I of the sealing usefulness in the part that is stored in thin communication paths 360, thereby can maintain the fluid-tight state that maintains liquid in the part of thin communication paths 360 more steadily in the long term.
In addition, in above-mentioned print cartridge 1, in a toner cartridge main body, divide and form three ink accommodating chambers, but the quantity of the ink accommodating chamber that is equipped with in the toner cartridge main body can be set at any number more than three, the outfit quantity of ink accommodating chamber is many more, bubble cuts storage multipleization more, thereby can improve the performance that stops bubble B to move downstream.
Then, illustrate according to Figure 13～Figure 14 depleted or inject an embodiment of the method for ink I when being reduced to ormal weight to this print cartridge of finishing using 1 as the ink I in the above-mentioned print cartridge 1.
At first, the reinject structure of device of employed ink describes in the method for implanting to present embodiment.
As shown in figure 13, the ink device 600 that reinjects comprises: ink injects unit 610, is connected with the inlet of offering on print cartridge 1 by perforation processing 601; And vacuum draw unit 620, be connected with the ink supply aperture 50 of toner cartridge main body 10.
Ink injects unit 610 and comprises: China ink jar 611 stores the ink I that fills; Pump 613, with the ink I in this China ink jar 611 to stream 612 force feeds that are connected with described inlet 601; And valve 614, between described pump 613 and inlet 601, open and close closed channel 612.
In the present embodiment, considered the 26S Proteasome Structure and Function of toner cartridge main body 10, the position that processes the inlet 601 that forms by toner cartridge main body 10 is bored a hole is equipped to the through hole 351 at the upstream extremity place that is positioned at thin communication paths 360 and is communicated with, and described thin communication paths 360 constitutes the part of ambient air flow path 150.
The inlet 601 that is communicated with through hole 351 forms as follows.
At first, pull down cover 20, expose the film 80 of the face side that is deposited over toner cartridge main body 10 from print cartridge 1.Then, consistently on film 80, offer the hole, form inlet 601 thus with through hole 351.In addition, for example be provided with sealing ring etc. on the leading section of the stream 612 in inserting this inlet 601, when described leading section was compressed against on the through hole 351, the container wall around sealing ring and the through hole 351 was close to airtightly, thus the state that 360 one-tenth of stream 612 and through holes are connected airtightly.
In addition, the upstream and be communicated with ambient air flow path 150 that the inlet 601 on the toner cartridge main body 10 is positioned at the upstream extremity of thin communication paths 360 gets final product, and the outfit position of inlet 601 is not limited to above-mentioned embodiment.
For example, also can be set at as shown in Figure 14 with to the relative position P1 of the intercommunicating pore 322 of the 70a of the gas-liquid separation chamber opening that constitutes gas-liquid separation filter 70.At this moment, peel off the gas-liquid separation membrane 71 that constitutes gas-liquid separation filter 70 and stream 612 is connected with through hole 322.
In the present embodiment, carry out following operation at first successively: inlet forms operation, offers the inlet 601 that is communicated with ambient air flow path 150 on toner cartridge main body 10, and this inlet 601 is positioned at the upstream of the upstream end portion of thin communication paths 360; The vacuum draw operation is removed ink and the residual gas that remains in inside by vacuum draw unit 620 from ink supply aperture 50 suctions; The liquid injection process injects unit 610 injects ormal weight from inlet 601 ink I by ink; And sealing process, after finishing, the liquid filling work procedure seals inlet 601.Thus, the print cartridge 1 of finishing using is regenerated as the print cartridge (liquid container) that can reuse.
Also can after carry out above-mentioned vacuum draw operation as mentioned above, between suction operation and liquid filling work procedure, keep the operation of decompression state, and then carry out the operation of filling liquid.
In addition, also can the vacuum draw operation begin the liquid filling work procedure midway, perhaps also can when carrying out the vacuum draw operation, carry out the liquid filling work procedure.
In the liquid filling work procedure, specifically, when beginning vacuum draw operation, synchronously make switch valve 614 be in closed condition with the suction operation, make and inject the inlet 601 of unit 610 to before injecting, becoming decompression state between the stream 612 from ink, open switch valve 614 then, thus can be in aforesaid three kinds of situations, that is: 1. situations of carrying out vacuum draw operation and filling work procedure successively; 2. make the situation of the part repetition of vacuum draw operation and filling work procedure; With carry out the vacuum draw operation when roughly synchronously carrying out the situation etc. of filling work procedure, under the considerably less situation of the intake of air, carry out liquid at short notice and fill, thereby the quality of regeneration print cartridge can not descended.
In addition, when the degassing degree of the ink I that recharges very high (dissolved air is few, the ratio of dissolved air little), can the quality of regeneration print cartridge can not descended by control vacuum draw unit 620 so that the ink injection rate of liquid filling work procedure does not comparatively slowly have the liquid filling that bubble is taken in.
Sealing process specifically waits the treatment process of carrying out the air-tightness sealing by bonding or deposited diaphragm seal on inlet 601.In addition, the state of the inlet 601 when the print cartridge state when reclaiming or regeneration are handled is difficult to wait when carrying out the air-tightness sealing by diaphragm seal bonding, deposited, also can utilize the encapsulant (soft resin material, bonding agent etc.) beyond the film that can carry out the air-tightness sealing.
And, also can increase the operation that the regeneration print cartridge of the sealing process that is through with is encapsulated with gas barrier material (gas barrier film or gas barrier property metal material, aluminium etc.), therefore the regeneration print cartridge of Zhi Zaoing can keep more stable regeneration quality at the environment that can directly not contact before reaching in consumer's hand through the process of circulation once more in the process of circulation like this.And,, can keep more stable regeneration quality by under the state that the air in the package of gas barrier material has been carried out the degassing, the regeneration print cartridge being encapsulated.
In the present embodiment of above explanation, the processing of toner cartridge main body 10 being carried out in order to inject ink I comprises: for the upstream in the upstream end portion of thin communication paths 360 is communicated with ambient air flow path 150, offer the processing of the inlet 601 that is used to inject ink; And the processing that after filling ink I, seals inlet 601.Above-mentioned processing is simple processing.Therefore, processing cost is low, and can save time and the labour.
And, in the present embodiment, comprise removing and remain in the inner ink and the vacuum draw operation of residual gas from ink supply aperture 50 suction, therefore at the liquid filling work procedure that injects the ink of ormal weight from inlet 601, each ink path of navigation 380,420,440 of toner cartridge main body 10 and each ink accommodating chamber are managed is reduced pressure atmosphere, thereby not only can ink be filled in the ink accommodating chamber 370,390,430 efficiently, but also can be filled into each corner until all ink path of navigation of ink supply aperture 50.
In addition, the bubble that can sneak into when the outside is discharged at filling ink I from ink supply aperture 50 by vacuum draw, perhaps utilize reduced pressure atmosphere in the container that forms by vacuum draw with the gas bubble that flows into, eliminate in liquid.
Therefore, the bubble of sneaking into when injecting ink I can not suspend or adheres to and remain on the stream wall at ink accommodating chamber or ink path of navigation, therefore, for example can not take place to cause the unfavorable condition that the ink remaining amount sensor can't operate as normal near the test section of ink remaining amount sensor owing to bubble remains in.
In addition, because therefore the position that inlet 601 is set can be injected into ink in the part of this thin communication paths 360 for the upstream as the part of the thin communication paths 360 of the part of ambient air flow path 150.
Be filled into ink in the part of the thin communication paths 360 in the ambient air flow path 150 and can intercept the ink in the ink accommodating chamber 370 and the atmosphere outside of ambient air flow path 150, thereby required Min. is arrived in the contact inhibition of ink I in the ink accommodating chamber 370 and extraneous gas, can prevent the deterioration of ink I thus, make the function (preventing the evaporation of the moisture in the stored ink etc.) of the part of this thin communication paths 360 identical when reverting to the container coming of new.Promptly, according to said structure, get final product when when the print cartridge 1 of finishing using injects ink, toner cartridge main body 10 being carried out less processing, and can under the situation of the various functions of not damaging this print cartridge 1, inject ink, thereby can utilize the print cartridge 1 of finishing using at low cost.
And by this print cartridge is provided, print cartridge is prolonged as the life of product of container, therefore can help to economize on resources, prevent the pollution of the environment.In addition, because cost is low,, therefore help to reduce the use cost of inkjet recording device so print cartridge at a low price can be provided.
The employed ink device 600 that reinjects specifically can replace with the utensil that obtains easily when carrying out present embodiment.
For example, can use the injector that constitutes by body and piston as syringe to replace, perhaps also can use the additional bottle that in the PET bottle that can be out of shape, accommodates additional ink to replace.
In addition, liquid container of the present invention is not limited to the print cartridge shown in above-mentioned each embodiment.In addition, the liquid consuming device with container installation portion that liquid container of the present invention is installed also is not limited to the inkjet recording device shown in the above-mentioned embodiment.
