With inject posture with ink after liquid injection port 304 is injected into liquid accommodating chamber 340; With the sealing of liquid injection port 304 usefulness plug member 304 and become under the situation of using posture; Air in the liquid accommodating chamber 340 produces and expands, and negative pressure is kept in liquid accommodating chamber 340.In addition, be communicated with atmospheric air open port 318 through air receiving room 330 and keep atmospheric pressure.
Using under the posture, form the other end 352 of meniscus, be positioned at the position lower than record head 17.Thus, produce water-head d1.In addition, using under the posture, also will be called " water-head d1 just often " at the water-head d1 under the state of the other end 352 formation meniscus.
Through attract the ink of ink storeroom 204 with record head 17, ink storeroom 204 becomes more than the negative pressure of regulation.Become when ink storeroom 204 more than the negative pressure of regulation, then the ink of liquid accommodating chamber 340 supplies to ink storeroom 204 via flexible pipe 24.That is, the ink of the amount that flows out from record head 17 adds to ink storeroom 204 automatically from liquid accommodating chamber 340.In other words; From the attraction (negative pressure) of printer 12 sides greater than by with ink tank 30 in the ink level that contact of air receiving rooms 330 and the water-head d1 of the difference in height generation of the vertical of record head (nozzle in detail), thereby the ink quilt from liquid accommodating chamber 340 to 204 supplies of ink storeroom.
When the ink of liquid accommodating chamber 340 was consumed, the air G of air receiving room 330 (also being called " bubble G ") imported to liquid accommodating chamber 340 via interconnecting part 350.Thus, the liquid level of liquid accommodating chamber 340 descends.
Fig. 9 is the figure that is used to explain ink tank 30.State under the use posture of the ink tank 30 shown in Fig. 9 presentation graphs 7 (A).In addition, Fig. 9 supplies with the figure of the state (user mode) of ink to secondary jar 20 via flexible pipe 24 for ink tank 30 under the expression use posture.
As shown in Figure 9, when the ink of liquid accommodating chamber 340 becomes ormal weight when following, in order to prevent printer 12 unfavorable condition (leak source etc.) appears, and the user carries out replenishing of ink.For example, inject the limit line of the target in period as ink at can body 32 marks, and the water level of ink drop to the limit line when following the user replenish ink.At this, drop to the situation below the limit line with the water level of STA representation ink shown in Figure 9.When ink was injected into liquid accommodating chamber 340, shown in arrow YR, rotation ink tank 30 made liquid injection port 304 direction on vertical.
Figure 10 is the figure of expression ink to the injection state of ink tank 30.Figure 10 (A) be under the ink remaining amount state shown in Figure 9 with ink tank 30 from using the figure of posture change when injecting posture.Figure 10 (B) is the figure of the state of expression when the ink of normal amount has been injected in liquid accommodating chamber 340.Figure 10 (C) is the figure of the state of expression when too much ink has been injected in liquid accommodating chamber 340." inject the ink of normal amount to liquid accommodating chamber 340 " and be meant that the ink of not enough ormal weight is accommodated in the situation in the liquid accommodating chamber 340.For example, be to point to liquid accommodating chamber 340 injection inks to be positioned at the position of more leaning on the below than liquid injection port 304 until the liquid level of ink.In addition, " injecting too much ink to liquid accommodating chamber 340 " is meant, injects ink until the ink of taking in more than the ormal weight to liquid accommodating chamber 340.For example, be to point to liquid accommodating chamber 340 to inject ink reaches liquid injection port 304 until ink degree.
Shown in Figure 10 (A), plug member 302 dismountings (Fig. 9) to being assemblied in liquid injection port 304 when injecting ink are injected ink from liquid injection port 304.In addition, the injection of ink is under the state that connects ink tank 30 and secondary jar 20 through flexible pipe 24, to carry out.Form meniscus (liquid bridges formation) at the nozzle of record head 17 (Fig. 8), only otherwise apply external force (piezoelectric element imposes on the pressure of ink), ink just can not be from nozzle ejection.That is,,, and remain in the liquid leading-out portion 306 so the inks in the liquid leading-out portion 306 that is communicated with nozzle can be to the refluence of liquid accommodating chamber 340 sides because the nozzle of record head 17 is being held ink with certain trying hard to keep.
Shown in Figure 10 (A), under the few state of ink remaining amount, from using posture change when injecting posture, liquid maintaining part 345 suppresses other parts that inks flow out to liquid accommodating chamber 340.That is, partition wall portion 342 obstruction inks flow to the direction (Z axle positive direction) away from an end 349.Therefore, injecting under the posture, can keep the water level higher in liquid maintaining part 345 than other parts.More detailed, can the water level of liquid maintaining part 345 be maintained more than the height of an end 349 through partition wall portion 342.Thus, even under the few situation of ink remaining amount, the ink that also can make ink and liquid maintaining part 345 in the liquid leading-out portion 306 is not via air ground continued presence.Thus, can reduce air when ink injects (bubble) from an end 349 influent leading-out portions 306 and via the possibility of flexible pipe 24 to secondary jar of 20 inflows.Thus, because air can not flow into record head 17 (Fig. 5) side when ink injects, so can suppress to beat the leak source that causes the decline of print quality by sky.
Shown in Figure 10 (B), under the situation of the ink that has injected normal amount to liquid accommodating chamber 340, injecting under the posture, the ink level Lf1 of liquid accommodating chamber 340 is positioned at the position of more leaning on the below than liquid injection port 304.At this, injecting under the posture, because the height H 1 of liquid injection port 304 is lower than the height H 2 of atmospheric air open port 318,, can prevent that ink from overflowing from atmospheric air open port 318 so inject in liquid accommodating chamber 340 under the situation of ink of normal amount.
In addition, shown in Figure 10 (C), even when the water level of ink arrives liquid injection port 304, can prevent that also ink from overflowing from atmospheric air open port 318 injecting too much ink.In addition, owing to can when ink injects, reduce 316 whole possibilities of being soaked of sheet member, so function that can long term maintenance sheet member 316 by ink.
Like this, the ink tank 30 of first embodiment liquid injection port 304 under the injection posture is lower than atmospheric air open port 318.Thus, the possibility that ink overflows from atmospheric air open port 318 in the time of can reducing the ink injection.In addition; Owing to have liquid maintaining part 345; Even so ink remaining amount tail off and with ink tank 30 from use posture change for the situation of injecting posture under, also can keep ink and the ink continuum of states (Figure 10 (A)) of liquid maintaining part 345 in the liquid leading-out portion 306.Thus, can ink be injected under the situation of liquid accommodating chamber 340, reduce air flows into record head 17 via liquid leading-out portion 306, flexible pipe 24 possibility.
B-2. second embodiment:
Figure 11 is the figure that is used to explain the ink tank 30a of second embodiment.Figure 11 (A), (B) are the suitable figure of Fig. 7 (A) with first embodiment.Figure 11 (A) is the figure of the formation of the ink tank 30a that is used to explain second embodiment.Figure 11 (B) is the figure that is used to explain the state of the ink tank 30a when the ink injection rate is too much.Be the structure of liquid accommodating chamber 340a and the height and position that injects the liquid injection port 304a under the posture with ink tank 30 differences of first embodiment.Other structures are identical with first embodiment, so mark identical label and omit explanation.In addition, the ink tank 30a of the second embodiment also ink tank 30 with first embodiment is the same, is used for liquid injection system 1 (Fig. 2).In addition, for ease of understanding, be shown in broken lines plug member 302 among Figure 11 (A).
Shown in Figure 11 (A), liquid injection port 304a is to be lower than atmospheric air open port 318 under the posture and to be lower than an end 351 of interconnecting part 350 that is the mode of opening 351 is formed on the can body 32 injecting.That is, injecting under the posture, the height H 1 of liquid injection port 304a is less than the height H 2 of atmospheric air open port 318 and the height H 3 of an end 351.
And liquid accommodating chamber 340 possesses the air-storage chamber 341 with volume V 1.Air-storage chamber 341 likens the part that for one of liquid injection port 304a distolateral opening 304m (being called " lower ending opening 304m "), promptly is formed on the position higher than the opening 304m on the wall of liquid accommodating chamber 340 to for being located in a part of injecting liquid accommodating chamber 340 under the posture.Air-storage chamber 341 is served as reasons and is formed the formed concavity shape of wall of liquid accommodating chamber 304m, is injecting under the posture towards vertical lower direction opening.In other words, air-storage chamber 341 for inject deleading under the posture hang down beyond the direction around (direction) the concavity shape of being surrounded by the wall of liquid accommodating chamber 340.Air-storage chamber 341 is injecting when to liquid accommodating chamber 340 in, injecting too much ink up to the degree of the open upper end 304p of ink arrival liquid injection port 304a under the posture, also can store the air (volume V 1) of ormal weight.In other words, no matter air-storage chamber 341 can both be stored the air of ormal weight volume (volume V 1) at least in the injection rate of injecting ink under the posture.Wherein, using under the posture (Z axle negative direction becomes the posture of vertical below), in the part of liquid accommodating chamber 340, the part that occupies the position more than the residing height of liquid injection port 304a is defined as inlet adjacency section 343.That is, inlet adjacency section 343 is at the height that uses more than the bottom 304f that is positioned at liquid injection port 304a under the posture.Here, when the volume with inlet adjacency section 343 was made as V2, ink tank 30a satisfied V1 >=V2.
