Ink path of navigation 440 is ink flow paths from the ink discharge outlet 432 of surge chamber 430 to differential valve 40 that introduce ink from.
For present embodiment, the ink inflow entrance 391,431 of each ink accommodating chamber in each ink accommodating chamber, all be arranged on the top of the ink discharge outlet 371,311 that is provided with in each accommodating chamber and be positioned at the ink accommodating chamber diapire 375,395,435 near.
Below, at first with reference to figure 8 to Figure 12, to from describing as the top ink accommodating chamber 370 of main ink accommodating chamber ink path of navigation to ink feed portion 50.
Top ink accommodating chamber 370 is ink accommodating chambers of the upstream (upper) in the box main body 10, as shown in Figure 8, is formed on the face side of box main body 10.This top ink accommodating chamber 370 is the only about half of ink housing regions that occupy the ink accommodating chamber, is formed on the only about half of part that makes progress from box main body 10.
On the recess 374 of the diapire 375 of top ink accommodating chamber 370, offer the ink discharge outlet 371 that is connected with ink path of navigation 380.This ink discharge outlet 371 is positioned at than on the lower position of the diapire 375 of top ink accommodating chamber 370, even thereby the ink level F in the top ink accommodating chamber 370 drops to diapire 375, this ink discharge outlet 371 also is positioned at more below than the ink level F of this moment, thereby can continue stably to derive ink I.
As shown in Figure 9, ink path of navigation 380 is formed on the rear side of box main body 10, ink I is imported the bottom ink accommodating chamber 390 of below from the top.
Bottom ink accommodating chamber 390 is the ink accommodating chambers that import the ink I that stores in the top ink accommodating chamber 370, as shown in Figure 8, be the only about half of ink housing region that occupies the ink accommodating chamber of the face side that is formed on box main body 10, be formed on only about half of downward part from box main body 10.
The ink inflow entrance 391 that is communicated with ink path of navigation 380 is opened on the connection stream of diapire 395 belows that are configured in bottom ink accommodating chamber 390, flows into via this connection stream from the ink I of top ink accommodating chamber 370.
Bottom ink accommodating chamber 390 is used up sensor by the ink discharge outlet 311 of break-through diapire 395 with the upstream side ink and is connected stream 400 and is connected.Use up sensor at the upstream side ink and connect the labyrinth stream that is formed with three-dimensional in the stream 400, utilize this labyrinth stream to catch the bubble B of inflow before ink is used up so that it does not flow to the downstream.
The upstream side ink is used up sensor and is connected stream 400 and be connected stream 410 and be connected via use up sensor as the ink entry portion 427 of through hole and downstream ink, and ink I uses up sensor connection stream 410 via the downstream ink and is introduced in the ink surplus sensor 31.
Ink I in the introducing ink surplus sensor 31 passes the cavity (stream) in the ink surplus sensor 31, introduces the ink path of navigation 420 of the rear side that is formed on box main body 10 from the ink discharge outlet 312 as the cavity outlet.
Ink path of navigation 420 forms from ink surplus sensor 31 structure of direct ink I obliquely upward, and is connected on the ink inflow entrance 431 that is connected with surge chamber 430.Thus, the ink I that flows out from ink surplus sensor 31 is incorporated into the surge chamber 430 via ink path of navigation 420.
The ink I that flows in the differential valve 40 guides the downstream into by differential valve 40, and introduces outlet stream 450 via through hole 451.Outlet stream 450 is connected with ink feed portion 50, and ink I is supplied to the inkjet recording device side via the ink supply pin 240 that inserts in the ink feed portion 50.
In addition, use up sensor at the upstream side ink and connect and to be provided with the bubble of catching the bubble B that sneaks into ink I in the stream 400 and to cut and deposit stream 713, this upstream side ink is used up sensor, and to connect stream 400 be the detection position of ink surplus sensor 31 and the part of the ink path of navigation between the bottom ink accommodating chamber 390.
As Figure 13 and shown in Figure 14, this bubble cuts the approximate rectangular shape that the general structure of depositing stream 713 integral body is the bottom of including container body 10 in.
As shown in figure 14, cut for this bubble and to deposit stream 713, be formed with ink supply water I at the substantial middle place of upper surface from the ink discharge outlet (inlet) 311 that bottom ink accommodating chamber 390 flows into, on the lateral surface that is positioned at sensor one side, be formed with the ink entry portion (outlet) 427 that discharges ink I.
As Figure 14 and shown in Figure 15, this bubble cuts to be deposited stream 713 and is combined by a plurality of vertical direction transformation component 721a～721g and a plurality of horizontal direction transformation component 723a～723f, form the numerous complicated flow passage structure of bend, wherein, described vertical direction transformation component 721a～721g oppositely is transformed into vertical direction with the flow direction of ink I, and described horizontal direction transformation component 723a～723f makes it become horizontal direction about 90 degree of the each variation of the flow direction of ink I.
And, this bubble cuts to be deposited stream 713 and is formed with bubble collection space 724a～724c in stream many places midway, described bubble collection space 724a～724c and described bubble cut the front and back stream that the port of export of depositing stream 713 adopts the position, be that standard stream sectional position A (with reference to Figure 15) compares, flowing path section is expanded vertically upward.
For illustrated embodiment, in bubble collection space 724a～724c, will lean on the bubble collection space 724c in downstream to be set at maximum volume most.
In addition, cut at the bubble of present embodiment and to deposit in the stream 713, be formed with the bubble collection space 725 that blocks at stream midway.
In addition, to cut and deposit the ink discharge outlet 311 that stream 713 connected be that diameter is the following circular cross-section stream of 2mm to bubble.In addition, in the present embodiment, bubble cuts to be deposited stream 713 and is positioned at the upstream side ink and uses up the end by bottom ink accommodating chamber 390 1 sides that sensor connects stream 400, and bubble cuts the inlet of depositing stream 713, is that ink outlet 311 also is to use up the ink supply port (liquid supply port) that sensor connects stream 400 from bottom ink accommodating chamber 390 to the upstream side ink.
In addition, in the present embodiment, bubble cuts to be deposited stream 713 and forms by the resin injection molding, constitutes the flowing path section that bubble cuts each stream of depositing stream 713 and is set to rectangle.
In the print cartridge 1 of above explanation, because waiting, vibration can make that the air in the ink accommodating chamber is mixed in ink I during carrying after manufacturing, perhaps in use because the vibration or the variations in temperature of print cartridge 1 are sneaked among the ink I bubble B, even in these cases, for using up sensor and connect floating bubble B among the ink I the stream 400 flowing into the upstream side ink that flows to ink feed portion 50 from bottom ink accommodating chamber 390, when its from than be arranged on the upstream side ink use up detection position that sensor connects stream 400 ink surplus sensor 31 midway more by the bubble of upstream cut deposit stream 713 by the time, also can be owing to being filled in that this bubble cuts the ink I that deposits in the stream 713 and on this bubble B effect its buoyancy that flows into downstream of prevention is arranged.Therefore, bubble B from ink I, isolate and be captured (with reference to Figure 15).Thereby bubble B can not flow into ink surplus sensor 31 sides.
Therefore, sneaking into bubble B among the ink I of bottom ink accommodating chamber 390 can not be attached near the ink surplus sensor 31 that is arranged at the ink feed portion 50, thereby the liquid residue test section of ink-jet recording apparatus can flase drop not be measured the ink surplus vanishing of bottom ink accommodating chamber 390 or is decreased to the situation of ormal weight, and can detect the ink surplus vanishing of ink accommodating chamber 390 exactly or be reduced to the situation (what is called is about to use up) of ormal weight.
In addition, in the print cartridge 1 of present embodiment, bubble cuts deposits stream 713 by being a plurality of vertical direction transformation component 721a～721g of vertical direction with flow-reversal and being that a plurality of horizontal direction transformation component 723a～723f of horizontal direction combine with flow-reversal, therefore can save the space and constitute three-dimensional complicated flow passage structure, separate the effect of the bubble B among the ink I by the direction transformation portion performance of each flow direction.Thereby, the ink I that flows to ink feed portion 50 is before arriving ink surplus sensor 31, accept repeatedly the seizure of bubble B is handled, become the state that the bubble B that sneaks into is separated fully removal, thereby can prevent from reliably to be attached to and to cause flase drop to be surveyed on the ink surplus sensor 31 owing to being blended into bubble B among the ink I.
In addition, in the print cartridge 1 of present embodiment, the bubble B that separates from ink I in the 721a～721g of direction transformation portion, the 723a～723f that flows to is stored in bubble collection space 725a, the 725b that compares bubble collection space 724a～724c that flowing path section is expanded vertically upward with the front and back stream or block, can unify to store a large amount of bubble B by these bubble collection spaces 724a～724c, 725a, 725b, thereby can eliminate the situation that bubble B is caught in leakage that the deficiency owing to bubble collection space capacity produces.
In addition, because the stream before and after it is positioned at the below of bubble collection space, thereby can on the gas in being stored in bubble collection space 724a～724c, act on its approaching buoyancy of stream downwards of prevention is arranged by being filled in ink I in this bubble collection space.Thereby even the strong vibration of print cartridge 1 effect to unloading from equipment in use, when perhaps acting on the impact that causes because of whereabouts etc., the gas that is stored in the bubble collection space also is difficult to flow to outside the bubble collection space.In addition, can store a large amount of bubble B by enough bubble collection spaces.
In addition, just in case the gas that stores in bubble collection space is owing to the vibration or the impact that act on the print cartridge 1 flow to adjacent flow passages, effluent air also can be positioned at the vertical direction transformation component in its downstream or the bubble collection space that blocks is caught once more or stored, thereby can't arrive ink surplus sensor 31.
Therefore, even in use act on judder at the print cartridge 1 that unloads from equipment, when perhaps acting on the impact that causes because of whereabouts etc., being blended into bubble B among the ink I of bottom ink accommodating chamber 390 can not be attached near the ink surplus sensor 31 that is installed on the ink feed portion 50 yet, the liquid residue test section of ink-jet recording apparatus can not surveyed the ink surplus vanishing of bottom ink accommodating chamber 390 or be reduced to ormal weight by flase drop, thereby can detect reliably.
In addition, in the print cartridge 1 of present embodiment, ink from bottom ink accommodating chamber 390 exports, is ink outlet (bubble cuts the inlet of depositing stream 713) the 311st, the circular cross-section stream that diameter 2mm is following, ink discharge outlet 311 has formed the meniscus that prevents that bubble B from flowing out, thereby can suppress bubble B and flow to ink surplus sensor 31 1 sides from ink accommodating chamber 390, alleviate bubble and cut the burden of depositing the bubble capture on the stream 713, thereby can improve the reliability that prevents that bubble B from adhering to ink surplus sensor 31.
In addition, in the print cartridge 1 of present embodiment, flowing path section is rectangular, thereby compare with the situation that forms circular cross-section, between parallel stream, wasting space can be do not stayed, complicated stream can be formed to high-density, in addition, cut under the situation of depositing stream 713 forming bubble by ester moulding, also can improve forming property.
And, at flowing path section is under the situation of rectangle, with stream is that the situation of circular cross-section is compared, can form the slow zone of flowing in the corner of rectangle flowing path section portion, its inner upper corner portion plays a part the bubble collection space held back by the isolated bubble B of direction transformation portion that flows to, thereby the seizure of bubble B or collect also is easy to.
In addition, cut at bubble and to deposit stream 713 midway, perhaps, also can dispose the porous plastid of catching bubble B by the ink path of navigation of upstream midway than the detection position of ink surplus sensor 31.
So, can more effectively catch the bubble that is blended in the ink owing to be arranged on stream porous plastid midway, thereby can improve the capturing efficiency of bubble, thereby can improve the reliability of bubble capture.
As mentioned above, above-mentioned print cartridge 1 has adopted the structure of stream being caught or collecting bubble to all directions conversion, on all directions, thereby no matter which kind of attitude print cartridge 1 is in, and can both prevent reliably that bubble B from reaching ink surplus sensor 31.Therefore, greatly improve the precision that accurate detection ink is used up, prevented to be created in the problem of replacing print cartridge 1 under the situation of residual ink I.
Then, illustrate from the ambient air flow path 150 of atmosphere opening hole 100 to top ink accommodating chamber 370 with reference to figure 8～Figure 12.
