Figure 10 A shows a kind of ink feed control device 150 of example.Ink feed control device 150 comprises partition wall 970, diaphragm valve 900, side (body side) connected chamber 912, supply side connected chamber 906 and 908, deformation adjustment part 980 and helical spring 907.Ink feed control device 150 is fixed on the box body 120 by fixed part 151.
As the height of the carinate part 904 of deformation adjustment part 980 height less than the projection 913 of diaphragm valve 900.And the height of setting carinate part 904 forms clearance delta g (shown in Figure 10 B) and seals intercommunicating pore 910 reliably with the projection 913 that allows diaphragm valve 900.
In the print cartridge 100 with above structure, connector inserts in the ink supply port 160 supply valve 13 is pressed inwards.Like this, supply valve 13 is opened, and the air in the box is emitted.Deflating makes diaphragm valve 900 revolt springs 907 displacements, reduces the pressure in liquid supply side container cavity 292 and 294 thus.Under this state, when when first ink entrance 161 injects inks, ink is introduced into liquid supply side container cavity 292 and 294 and flow channel, make liquid supply side container cavity 292 and 294 and flow channel be full of ink.In addition, when from second ink entrance, 162 injection inks, ink flows into atmospheric side container cavity 270.When having charged into ink, seal 604 is placed on the ink supply port 160 to bond on it.In addition, seal 132 is placed on first ink entrance 161 and second ink entrance 162 to bond on it weakening under the pressure.Like this, the inside of box can be sealed to and have pressure below atmospheric pressure.
Box is put into vacuum packet 101 subsequently, is being lower than the opening that weakens pressure lower seal vacuum packet 101 of cassette interior pressure thereafter.Like this, encapsulate box weakening under the pressure, as shown in figure 12.
Under this state, atmos-valve 254 makes ink container cavity 111 and outside not be communicated with ink container cavity 111 and outside isolated.So, film 130 expansions of the opening of sealing box body 120.But because lid 140 closely contacts with film 130, film 130 is controlled by lid 140.Therefore, can suppress film 130 outside expansion amount as far as possible little.
Because film 130 is expansion slightly as mentioned above, the negative pressure in the vacuum packet 101 is passed film 130 and is acted on all inks in the ink container cavity 111, so continue to discharge air from ink.Print cartridge 100 is distributed under this state.Therefore, up to bringing into use print cartridge, can keep pressure in the ink container cavity and be lower than atmospheric pressure and keep ink in the ink container cavity to be in and discharge air state, because the air that comprises in the ink container cavity leaks the space that enters between vacuum packet and the box.
Take out print cartridge when bringing into use from vacuum packet 101, atmospheric pressure acts on the film 130 of print cartridge.So pressure in the atmospheric side container cavity 270 and the pressure differential between atmospheric pressure make film 130 to atmospheric side container cavity 270 strains, therefore reduce the degree of negative pressure in the atmospheric side container cavity 270.
As shown in figure 14, this meniscus that can reduce the nozzle opening place that is formed on fluid jetting head is drawn in the degree of print cartridge when print cartridge is installed on the support 200, and the negative pressure in the print cartridge causes described meniscus.
Especially in this example, the zone that forms the ink container cavity is sealed fully by film 130.So, compared by the situation of film 130 parts sealing with the ink container cavity, can remove negative pressure (being that pressure can increase) quickly.
Below, description is not used the situation of aforementioned film 130 or can not fully be removed the situation of negative pressure (being that pressure can not increase) because of the restriction of selection film 130 etc.Below describe and also relate to removing the effective structure of negative pressure more reliably.
When print cartridge is placed on the support 200 as shown in figure 13, and when packing into by rotating lever 204 as shown in figure 14 subsequently, ink feed pin 201 enter ink supply port 160 and subsequently atmos-valve 254 opened by the functional unit 202 on support 200 bottoms.
When ink feed pin 201 had contacted ink supply port 160, the rear surface of diaphragm valve 900 was communicated with atmosphere via the fluid jetting head 203 that is communicated with ink feed pin 201.Because the pressure in this moment ink container cavity is low, atmospheric pressure along towards the directive effect of ink supply port 160 on diaphragm valve 900 and make diaphragm valve 900 strains take place towards partition wall 970.But diaphragm valve 900 touches the deformation adjustment part 980 that is formed on the partition wall 970, thereby is stopped in preposition.
This deflection is approximate corresponding to the clearance delta g in this example, and this compares quite little with the situation that does not form deformation adjustment part 980, because deformation adjustment partly is the distortion that the carinate part 904 on the partition wall 907 has suppressed diaphragm valve 900 in this example.So the meniscus at the nozzle opening place of fluid jetting head 203 is stopped in such position, spurred the formation not influence of meniscus slightly to drop although make.
And, can think that forming diaphragm valve 900 is in order to allow the height by the projection 913 that reduces diaphragm valve 900, make the outer rim of diaphragm valve 900 touch partition wall 970 by the slight displacement of diaphragm valve 900.But in this case, it is exactly that the gap of 900 of partition wall 970 and diaphragm valves becomes littler and the fluid resistance that increased ink that a problem is arranged, thereby has reduced the ability of ink feed.The another one problem has increased expense exactly, because should control the size of projection 913 with high accuracy.
When box 100 installed the consumption of ink of back in the fluid jetting head 203 fully, the pressure of the ink feed part side of ink feed control device 150 was reduced to predetermined pressure or littler.So, the diaphragm valve 900 of formation ink feed control device 150 bears ink supply port 160 on the more large tracts of land at its rear portion negative pressure.In addition,, can not stop this displacement, because the area of intercommunicating pore 910 openings is compared much smaller with the area at diaphragm valve 900 rear portions although the negative pressure of ink supply port 160 also works via intercommunicating pore 910.
If act on the rear portion of diaphragm valve 900, promptly diaphragm valve 900 overcomes spring 907 in the negative pressure that is communicated with on the face of a side with ink supply port 160, and then diaphragm valve 900 leaves partition wall 970.So the ink in the flow channel 296 flows into the diaphragm valve side of partition wall 970 via intercommunicating pore 918, and distinguishes via intercommunicating pore in the partition wall 970 910 and connection subsequently or flow channel 304 inflow ink supply ports 160.Ink flows into ink supply port 160 and do not increase fluid resistance, and is open because near the cut-away of carinate part 904 intercommunicating pore 918 divided.
When air is drawn in the atmospheric side container cavity 270 via intercommunicating pore 242, ink in the atmospheric side container cavity 270 is drawn in the first liquid supply side container cavity 292 via communication passage 295, makes the second liquid supply side container cavity 294 refill ink via being communicated with district 276.
When the ink of scheduled volume flows into ink supply port 160 in this way and makes that acting on pressure differential on the diaphragm valve 900 becomes when being lower than by spring 907 applied pressures, diaphragm valve 900 is pushed back towards partition wall 970, interrupts the flow channel of ink thus.
By repeating aforementioned process, the pressure in the ink supply port 160 can maintain predetermined negative pressure and be supplied to fluid jetting head to allow ink.
In above-mentioned example, described box 100 and be parallel to ink feed pin 201 and move the situation of installing.Perhaps, as shown in figure 16, box 100 is arranged to locating piece 190 is placed in the bottom and install by making to move for this zone rotation of fulcrum, can allow atmos-valve 254 before ink supply port 160 and 201 engagements of ink feed pin, to touch functional unit 202 in this case, thereby with 111 pairs of atmosphere openings of ink container cavity.
Said circumstances will be described in more detail.When print cartridge 100 has been mounted, because atmos-valve district 250 is opened, air just flows into atmospheric side container cavity 270 from atmospheric side path 210 via ink side path 230.So, removed the pressure that weakens in the print cartridge 100.Under this state, when the ink feed pin of ink-jet recording apparatus enters ink supply port 160, because the pressure that weakens in the print cartridge 100 is removed, the pressure on the ink feed oral-lateral that is higher than diaphragm valve that just becomes of the pressure on the ink holding portion side of diaphragm valve.Thus, can prevent that the ink in the fluid jetting head is attracted or is withdrawn into the shortcoming that print cartridge 100 also can avoid drawing in from the nozzle opening of fluid jetting head air reliably.
The utility model is effective in following situation in having the device of above structure, promptly, for example, be later than the ink feed pin and insert ink supply port owing to the inappropriate installation that forces box to insert along the direction that is parallel to the ink feed pin makes the opening of atmosphere postponed till.
In above example, deformation adjustment partly forms the carinate part of the sub-circular with the part of cutting.But a plurality of parts that the deformation adjustment part relative with the peripheral edge portion 905 of diaphragm valve 900 distributes on can the face by partition wall 970 form, thereby do not hinder the function of closing diaphragm valve 900.In this case, can obtain with above-mentioned example described in identical effect.
Figure 17 A, 17B and 18 show another example as the deformation adjustment part 980 of diaphragm valve 900 structures.The carinate part 914 of sub-circular can be formed on the outside of the projection 913 of diaphragm valve 900, with comprise intercommunicating pore 918 with partition wall 970 relative cut part.In this case, can obtain with above-mentioned example described in identical effect.In this example, carinate part 914 forms by this way, promptly height h1 be lower than diaphragm valve 900 projection 913 height h2 and can be when close diaphragm valve 900 at 970 formation of diaphragm valve 900 and partition wall clearance delta g, shown in Figure 17 B, thereby do not hinder the function of valve closing.
And in this example, when ink supply port 160 touched ink feed pin 201, ink supply port 160 was communicated with atmosphere via the fluid jetting head 203 that is communicated with ink feed pin 201.So, shown in Figure 19 A and 19B, the negative pressure that diaphragm valve 900 bears atmospheric pressure and bear atmospheric side container cavity 270 on opposite side on its ink feed part side, diaphragm valve 900 trends towards towards partition wall 970 strain taking place thus.But the carinate part 914 of diaphragm valve 900 touches partition wall 970, makes diaphragm valve 900 be stopped in preposition.So deflection is suppressed quite for a short time, although the nozzle opening place meniscus of fluid jetting head 203 is spurred the formation not influence of distortion to drop slightly thus.
In above example, the deformation adjustment of sub-circular partly forms has the part of cutting.Perhaps, the deformation adjustment part can be formed by a plurality of parts that distribute on the partition wall 970, thereby does not hinder the function of valve closing.In this case, can obtain identical effect.
In above example, the pressure-difference valve of print cartridge has such structure, wherein forms intercommunicating pore 910 and diaphragm valve 900 and move according to the pressure on the ink feed part side and open and close intercommunicating pore 910 around the center of partition wall 970.But the utility model may be used on having on the ink feed control section of structure shown in Figure 20 A.In the structure shown in Figure 20 A, partition wall 970 remove form in the excentral zone single intercommunicating pore 918 '; Around the center of partition wall 970, form projection 990; And around the center of diaphragm valve 900, form intercommunicating pore 992 by this way, make itself and projection 990 Elastic Contact.By the intercommunicating pore 992 of diaphragm valve 900 is contacted with projection 990, come the intercommunicating pore 992 of normally closed diaphragm valve 900.If reduce the pressure of ink feed part, the elastic force of diaphragm valve 900 resistance helical springs 907 is left projection 990, shown in Figure 20 B, supplies inks with the line shown in the A via the intercommunicating pore 992 of diaphragm valve 900 thus in Figure 20 B.In this case, can obtain identical effect described in the explanation with above-mentioned example.
Can be by carinate part 904 ' the regulate excessive deformation of diaphragm valve 900 towards partition wall 970 be set on the relative face of partition wall 970 and diaphragm valve 900, shown in Figure 21 A, carinate part 904 ' approach intercommunicating pore 918 ', have the part of cutting than projection 990 in the outer zone, perhaps on the relative face of diaphragm valve 900 and partition wall 970, form projection 914 ', around intercommunicating pore 992 and with the zone of the intercommunicating pore 918 of partition wall 970 ' relative in have the part of cutting.
Below, Figure 22 to 25 relates to the pressure that is used for liquid is injected the method and print cartridge 100 various pieces of print cartridge 100 according to another embodiment of the present utility model.Print cartridge shown in Figure 22 to 25 on basic structure and Fig. 1 to 11 shown in similar.But among the embodiment shown in Figure 22 to 25, partition wall 970 is not equipped with carinate part 904 and diaphragm valve 900 is not equipped with carinate part 914.Therefore, only describe shown in Figure 22 to 25 and Fig. 1 to 11 shown in box between different parts.
With reference to Figure 22, on the outer surface of film 130, lid 140 fits in film 130 and closely contacts, and makes the volume reduce film 130 and 140 spaces of lid as much as possible, film 130 be placed on the opening of box body 120 and bonds on it.So can prevent the damage film 130 that causes with collision such as projection and be contained in film 130 unsuitable expansions under the situation in the vacuum packet 101 when print cartridge 100.
Shown in Figure 23 A, ink supply port 160 comprises: supply valve 13, thus can open in the pressure effect lower slider of the ink feed pin of support; Seal member 12 is set to cooperate around the ink feed pin, and has the mouth of insertion 26; With bias component 14, form by helical spring, be used for supply valve 13 is pressed to seal member 12.Supply valve 13, seal member 12 and bias component 14 are in order to method assembling down.Bias component 14 is installed in the box body 120, and seal member 12 fits into ink supply port 160 subsequently.At last, supply valve 13 is pushed ink supply port 160 from inserting mouth 26.Like this, the process that does not just need fixing spring in the assembling.Only need just can finish assembling by the element that ink supply port 160 is installed.
On the outer rim 905 of diaphragm valve 900, form annular groove with according to pressure differential generation strain or move easily and seal or open intercommunicating pore 910.
And as shown in figure 22, the filter 130 that is used for filtering ink can be contained in side connected chamber 912.In this case, can stop the foreign particles that is included in the ink, guarantee the sealing function of diaphragm valve 900 thus to stop foreign particles moving downstream.Can also prevent obstruction such as the fluid jetting head of record head.Please note that the example shown in Figure 22 does not comprise carinate part 904.
In the print cartridge 100 with above structure, blast pipe 181 at first inserts ink supply port 160 in airtight mode and makes that supply valve 13 is further pushed inward, shown in Figure 23 A.So, supply valve 13 open and ink supply port 160 in air be discharged from.Therefore at this moment, diaphragm valve 900 bears the negative pressure of ink supply port 160 and overcomes spring 907 applied forces and leave partition wall 970 on the large tracts of land of diaphragm valve 900 rear surfaces.So the air in the ink container cavity 111 (270 and 290) is inhaled into ink supply port 160 via intercommunicating pore 910 and connection district 304.This suction continues preset time, and the pressure in the print cartridge 100 reduces to become vacuum up to the inside of print cartridge 100 thus.
Then, when ink ascending pipe 182 inserted first ink entrance 161 in the close mode of liquid, shown in Figure 23 B, ink was inhaled into and is in the ink container cavity 111 (270 and 290) that weakens under the pressure.So the nearly all space from liquid supply side container cavity 290 to ink supply port 160 all has been full of ink and has not contained air.
Next, pressing component 198 pushes inward the axle 264 of atmos-valve 254 to open atmos-valve 254, shown in Figure 24 A, makes the atmosphere of print cartridge 100 survey container cavity 270 and atmosphere is communicated with.Then, ink ascending pipe 183 with the close mode of liquid insert second ink entrance 162 and subsequently ink under pressure, inject atmospheric side container cavity 270.The process that please notes the process of opening atmos-valve 254 and inject ink can be carried out simultaneously.In this case, the required time of ink injection process can shorten.
Under this state, there is not pressure differential between ink container cavity 111 and the ink supply port 160.Therefore, diaphragm valve 900 both sides are that the pressure in the upstream of diaphragm valve 900 and downstream thereof is identical.So as shown in figure 22, diaphragm valve 900 keeps approximate straight.
Under this state, ink ascending pipe 184 inserts ink supply port 160 to the degree of depth of opening supply valve 13 in the close mode of liquid, and ink injects ink supply port 160 under pressure subsequently.So as shown in figure 25, the ink of pressurization flows into the downstream of diaphragm valve 900, i.e. the side that is communicated with ink supply port 160 of diaphragm valve 900 makes diaphragm valve 900 such strains, and promptly diaphragm valve 900 pericentral zones become to partition wall 970 protrusions.Under the state after just injecting pressurized ink, the area that diaphragm valve 900 bears pressure near on helical spring 907 sides greater than on the opposite side, and the cross-sectional area of the intercommunicating pore 910 of partition wall 970 is quite little.Therefore, diaphragm valve 900 is in the state that is pressed towards partition wall 970.
Then, when the extra ink of finishing scheduled volume injects, remove pressing component 198 atmos-valve 254 is moved on to the position of sealing, and ink ascending pipe 184 is shifted out from ink supply port 160.So, the support of supply valve 13 is removed from supply valve 13, supply valve 13 is biased parts 14 applied forces and cuts out thus.So, 900 the space from ink supply port 160 to diaphragm valve, promptly the pressure in the space in the downstream of diaphragm valve 900 becomes and is higher than in diaphragm valve 900 upstreams.
When having charged into ink, seal 604 is placed on the ink supply port 160 to bond on it.And, film 132 is placed on first ink entrance 161 and second ink entrance 162 to bond on it weakening under the pressure, thus in the inside of pressure below atmospheric pressure lower seal box.
Next, box is placed in the vacuum packet 101 and is being lower than the pressure lower seal vacuum packet 101 of cassette interior pressure subsequently.So, as shown in figure 12, encapsulate box weakening under the pressure.Feng Zhuan box is distributed under this state like this.During distributing, the shell wall that the air in the ink container cavity 111 passes print cartridge 100 leaks the space that enters between vacuum packet 101 and the box gradually.So, can under atmospheric pressure keep ink container cavity 111 and from diaphragm valve 900 to ink supply port the pressure 160 the space, can keep ink discharging under the air state thus.Because the ink that exists 160 the space from diaphragm valve 900 to ink supply port bears even is similar to the pressure that weakens of 111 of ink supply port 160 and ink container cavities, diaphragm valve 900 keeps caused strain when having charged into ink, and this will be clearly.
When the print cartridge 100 in being encapsulated in vacuum packet 101 like this takes out from vacuum packet 101, with regard to being placed on the support 200 as shown in figure 13, and when packing into by rotating lever 204 as shown in figure 14 subsequently, ink feed pin 201 enter ink supply port 160 and subsequently the functional unit 202 that is positioned on support 200 bottoms of atmos-valve 254 open.
When ink feed pin 201 had touched ink supply port 160, the rear side of diaphragm valve 900 (helical spring side) was communicated with atmosphere via the fluid jetting head 203 that is communicated with ink feed pin 201.Therefore, the ink pressure that acts on diaphragm valve 900 zones is released, and ink is pushed into ink feed pin 201 thus, and extra ink injects and makes diaphragm valve 900 that strain take place.
So negative pressure does not act on the ink feed pin 201, can prevent the shortcoming that the meniscus at the nozzle opening place of fluid jetting head 203 is attracted or retracts.
Finish in the above described manner when print cartridge 100 and to lay and when packing into, diaphragm valve 900 returns to original state, promptly returns to straightened condition as early as possible, as shown in figure 22.Therefore, can open and close diaphragm valve 900 according to the pressure differential (pressure reduction) between ink supply port 160 and the liquid supply side container cavity with the supply ink.
In above example, when having charged into the ink of scheduled volume, just carry out extra ink and charge into up to the central area of diaphragm valve 900 generation strain from ink supply port 160.Perhaps, can carry out ink in the following manner charges into.At first, pressing component 198 is pressed the axle 264 of atmos-valve 254 so that the atmospheric side container cavity 270 of box and liquid supply side container cavity 290 are communicated with atmosphere, shown in Figure 23 A and 23B inwards.Then, ink ascending pipe 181 and 182 inserts first and second ink entrances 160 and 162 in the close mode of liquid respectively, injects ink afterwards and reaches scheduled volume.
Then, pressing component 198 is retracted and is closed atmos-valve 254.Under this state, when ink is pressurized, carry out extra ink and charge into.The downstream area of diaphragm valve 900 retracted diaphragm valve 900 and therefore enters by the ink resistance helical spring 907 of pressurization.Then, pressing component 198 is opened atmos-valve 254 when finishing extra ink and charge into, 270 pairs of atmosphere openings of atmospheric side container cavity, the pressure of atmospheric side container cavity 270 when pressure in the liquid supply side container cavity 290 charges into extra ink is just compared and has been reduced thus.This pressure reduces to make diaphragm valve 900 resistance helical springs 907 applied pressures with intercommunicating pore 910 sealings.So, ink pressure from diaphragm valve 900 to ink supply port 160 the space is increased to than the relative higher pressure in atmospheric side container cavity 270 and the liquid supply side container cavity 290, make diaphragm valve 900 such strains, be that its central area becomes to partition wall 970 protrusions, as shown in figure 25.
As mentioned above,, act on by extra ink and inject and ink pressure on diaphragm valve 900 central areas of strain is released, thus effect and ink released enter ink feed pin 201 when finishing when being installed to box on the ink feed pin.Therefore, can prevent the shortcoming that the nozzle opening place meniscus of fluid jetting head 203 is attracted.
In above example, print cartridge has the structure of atmos-valve, and the engagement by print cartridge and tape deck is used for ink container cavity and atmosphere are communicated with.Perhaps, the utility model may be used on a kind of print cartridge, and wherein the engagement between print cartridge and tape deck is opened a part of path of being communicated with the atmospheric side of ink container cavity ink container cavity and atmosphere are communicated with.In this case, can obtain with above example described in identical effect.
Another embodiment in atmos-valve of the present utility model district 250 is described referring now to Fig. 2 to 7.According to present embodiment, atmos-valve district 250 comprises that the atmos-valve that holds atmos-valve 254 holds district 232.Atmos-valve district 250 also comprises intercommunicating pore 239, has the diameter than axle 264 the slightly larger in diameter of atmos-valve 254, and it is arranged in the lower wall that atmos-valve holds district 232.Intercommunicating pore 239 is also as flow channel.Spring 255 always makes the bottom of the axle 264 deflection boxes 100 of atmos-valve 254, makes the axle 264 of atmos-valve 254 can insert intercommunicating pore 239 slidably.So, atmos-valve 254 sealing intercommunicating pores 239 when print cartridge 100 is not installed in the box support 200 of balladeur train of ink-jet recording apparatus described below.So atmos-valve 254 is arranged to and can be moved along a direction, this direction is installed to direction on the support 200 of balladeur train perpendicular to print cartridge 100 substantially.In the time will being installed to print cartridge on the support, near parts (abutment member) 60 atmos-valve 254 is upwards pushed away, and open intercommunicating pore 239, near parts 60 the examples that are formed in the support of balladeur train near part.In addition, will be described below an aspect of the spring load of spring 255.
After ink was contained in the ink container cavity 111 of the print cartridge 100 with above-mentioned structure, print cartridge 100 was encapsulated in the vacuum packaging of being made by for example aluminium and at the pressure below atmospheric pressure lower seal.So ink container cavity 111 inside of print cartridge 100 also vacuumize and become to be lower than atmospheric pressure.When from then on vacuum packaging is opened under the state, print cartridge 100 will be exposed under the atmosphere.In this case, because atmospheric pressure is higher than the pressure in the ink container cavity 111, so the side that pressure is exposed to from atmos-valve 254 under the atmosphere is applied on the atmos-valve 254 to a side of ink container cavity 111.Because make atmos-valve 254 have above-mentioned bias force from a lateral deviation of ink container cavity 111 to the spring 255 of intercommunicating pore 239, the power that atmos-valve 254 is revolted spring 255 by atmospheric pressure moves up, and opens to be communicated with district 224.Therefore, ink container cavity 111 is communicated with by intercommunicating pore 239 and atmosphere, and the pressure in the ink container cavity 111 increases.So atmos-valve 254 can reduce the pressure differential between ink container cavity 111 and atmosphere.
When further reducing from the pressure differential between the further increase of the pressure of above-mentioned state ink container cavity 111 and ink container cavity 111 and atmosphere, the power of spring 255 becomes greater than the power that is applied to by the pressure differential between ink container cavity 111 and atmosphere on the atmos-valve 254, makes atmos-valve 254 seal intercommunicating pore 239 again.So intercommunicating pore 239 does not keep sealing when print cartridge 100 is installed in the ink-jet recording apparatus, make to prevent that ink from leaking from print cartridge 100.
As mentioned above, print cartridge 100 according to present embodiment, because in a single day the power of atmospheric pressure resistance bias component move up atmos-valve 254 and open and be communicated with district 224 when opening the vacuum packet of encapsulation print cartridge 100, by print cartridge 100 has just been reduced poor between pressure in the print cartridge 100 and atmospheric pressure to atmospheric exposure.So, when print cartridge 100 is installed on the ink-jet recording apparatus, prevent that print cartridge 100 from attracting ink from the record head of ink-jet recording apparatus, and can prevent to enter record head and the record head fault that causes by bubble.
And, as shown in Figure 5, because spring 255 in the present embodiment as bias component, can regulate how many ink container cavities 111 of each print cartridge 100 and the pressure differential between the atmosphere reduced by the spring load of selecting spring 255 suitably.For example, the spring load of spring 255 is low more, and the pressure differential when opening vacuum packet between ink container cavity 111 and the atmosphere is more little.
In addition, as above described with reference to figure 2 and 3, because 160 sealed 604 sealings of ink supply port, ink supply port 160 and atmospheric isolation, thus prevent that ink container cavity 111 is exposed under the atmosphere via ink supply port 1160.Therefore, be exposed to atmosphere following time when opening vacuum packet and print cartridge 100, atmos-valve 254 does not move with not losing efficacy and reduces negative pressure in the ink container cavity 111 reliably.
Though the utility model is illustrated by exemplary embodiment, but should be appreciated that, those skilled in the art can be under the situation that does not break away from spirit and scope of the present utility model, carry out multiple change and replacement, spirit and scope of the present utility model only are defined by the following claims.
