Fig. 1 is that expression will be installed to the sectional view of the state on the print cartridge 100 as the ink replenishing external member 1 of the utility model embodiment.Print cartridge 100 is to be used for for example print cartridge of printing equipment (not shown), and ink can roughly exhaust.In the print cartridge 100, in plastics system print cartridge shell 110, be formed with the ink supply port 102 that is used for providing ink to printing equipment.The inner space of print cartridge shell 110 is filled with negative pressure material 120.In print cartridge shell 110, relative with the formation face of ink supply port 102 to face on, be formed with ink hand-hole 112 and steam vent 114.Also can be pre-formed ink hand-hole 112 and steam vent 114, treat that ink uses up after, form ink supply port 102 when need replenishing ink again.Because print cartridge shell 110 is a plastics system, therefore can form the hole with simple tool (not shown) such as drill bits.
Deposited ink 10 in the ink bottle 20, the opening 22 of ink bottle 20 is jumped a queue by chimeric member 30.Being formed with ink discharge outlet 32 and airport 34 in the chimeric member 30, is to be used to be communicated with the inside and outside through hole of ink bottle 20.Owing to be to utilize ink bottle 20 storage inks 10, therefore,, the lid that does not show among the figure is installed in order to seal ink discharge outlet 32 and airport 34.Ink bottle 20 and chimeric member 30 constitute ink container 6.Ink bottle 20 is typically by polypropylene and forms, and pushes with hand and promptly is easy to generate distortion.In addition, chimeric member 30 can followingly constitute: the materials such as rubber that produce strain by meeting form and opening 22 connects airtight, and in addition, aftermentioned ink discharge nozzle 40 and providing ink nozzle 80 etc. and ink discharge outlet 32 and airport 34 are closely chimeric.
Airport 34 is connected with spray nozzle of the gas supply 80, and this spray nozzle of the gas supply 80 is disposed at the inside of ink bottle 20, extends to opening 22 opposition sides of ink bottle 20, promptly near the bottom (ink bottle 20 shown in Fig. 1 turns upside down, so the bottom among Fig. 1 is depicted in upside).In addition, said in this book " connection " comprises two kinds of situations: the situation that the space of hole, passage etc. links to each other, and between the member in the space with hole, passage etc., the spatial interpolation of a member is gone into the situation of other member.At the opening 22 of ink bottle 20 down the time, spray nozzle of the gas supply 80 has following length and gets final product: it is connected the opposition side end of side with airport 34, be that front end 84 arrives in the ullage space 14, this ullage space 14 is meant on the liquid level of ink 10, the spatial portion of air trapping; The ullage space 14 interior length that front end 84 arrives ink 10 are length-specific.The preferred rigid materials of spray nozzle of the gas supply 80 form, plastics such as vinyl chloride for example so that be inserted in the airport 34 of chimeric member 30, in addition, regardless of the configuration of ink bottle 20 towards, front end 84 all is positioned near the bottom of ink bottle 20.
Embed in the ink discharge outlet 32 of chimeric member 30 ink discharge nozzle 40 is arranged.Ink discharge nozzle 40 has cylindrical fitting portion 44, cylindrical insertion section 48 and extension 46, fitting portion 44 is embedded in the ink discharge outlet 32, insertion section 48 is embedded in the ink hand-hole 112 of print cartridge shell 110, extension 46 connects fitting portion 44 and insertion section 48, for area of section is wider than both cylindrical, and cover ink hand-hole 112.Be formed with ink via 42,,, connect insertion section 48 through extension 46 from fitting portion 44.Insertion section 48 sides of ink via 42 are connected with ink and inject pin 50.Ink discharge nozzle 40 is typically by the good plastics such as polyformaldehyde of dimensional stability and forms.
It is thin steel hollow needle that ink injects pin 50, be inserted into negative pressure material 120 depths of print cartridge 100, if be provided with device such as filter near the formation face of the ink supply port 102 of print cartridge shell 110 or around the ink supply port 102, then ink injects pin 50 and can arrive near these devices.Ink injects pin 50 and can be fixed by the ink via 42 that is inserted into ink discharge nozzle 40, also can use fixing means such as adhesive to fix.
Then, to using ink replenishing external member 1 to describe to the method that print cartridge 100 replenishes ink 10.As shown in Figure 1, concrete state is: on the top of print cartridge 100, the opening 22 of ink bottle 20 is disposed down, and the front end of fitting portion 44 sides of ink discharge nozzle 40 is arranged in ink 10, and the front end 84 of spray nozzle of the gas supply 80 is for being projected into the ullage space 14 of the ink 10 in the ink bottle 20.
So, form as lower channel: the ink 10 from ink bottle 20, through the ink via 42 of ink discharge nozzle 40, hollow bulb, the inside of print cartridge, the air flue 62 of exhaust nozzle 60, air hose 70, the spray nozzle of the gas supply 80 that ink injects pin 50, arrive the ullage space 14 in the ink bottle 20.Therefore, the ink 10 in the ink bottle 20 injects pin 50 by ink via 42, ink, falls in the print cartridge 100.That is to say that ink 10 is injected in the print cartridge 100 from ink bottle 20.Corresponding to the volume that is injected into the ink 10 in the print cartridge 100, decompression in the ink bottle 20, but the air that equates with this volume can be from print cartridge 100, by air flue 62, air hose 70 and spray nozzle of the gas supply 80, flow into ullage space 14, therefore pressure keeps balance, and ink 10 is continued to be injected in the print cartridge 100.Ink 10 spreads in print cartridge 100 by negative pressure material 120, and ink is stranded in the print cartridge 100.In addition, also following situation might take place: when beginning to inject ink 10, for example flowing to the air of air flue 62, air hose 70 and spray nozzle of the gas supply 80, the negative pressure material 120 from print cartridge 100 can sneak into the micro-ink 10 that remains in the negative pressure material 120, in air flue 62, air hose 70 and spray nozzle of the gas supply 80, produce bubble, thereby cause ink 10 to be difficult to flow.When this thing happens, can form air intake passage 390 (with reference to Figure 10) etc. in advance near the bottom of ink bottle 20, open air intake passage 390 etc. flow ink 10.That is to say, can be by opening air intake passage 390 etc., keeping ullage space 14 is atmospheric pressure, guarantees that ink 10 can pass through ink via 42, ink injects pin 50 and flows.Ink 10 seals air intake passage 390 etc. after beginning to flow at once.Can eliminate the bubble that is produced in air flue 62, air hose 70 and the spray nozzle of the gas supply 80 by the ink 10 that begins to flow.
As shown in Figure 2, if ink 10 is detained in nozzle insertion section 66 leading sections 68 of exhaust nozzle 60, then air flue 62, air hose 70 and spray nozzle of the gas supply 80 inner meetings flow into ink 10, rather than air.Fig. 2 is illustrated in ink replenishing external member 1 is installed under the state on the print cartridge 100, has injected the sectional view of the state of specified quantitative ink 10.Ink 10 flows in the spray nozzle of the gas supply 80, the hollow bulb that injects pin 50 by the ink via 42 and the ink of the ink 10 in air flue 62, air hose 70 and spray nozzle of the gas supply 80, ullage space 14, the ink bottle 20, ink discharge nozzle 40 constitutes the channel system of sealing, this channel system has two fluid passages, clamp ullage space 14, promptly be full of ink 10 in the fluid passage.When the liquid level of the ink 10 in the liquid level in the spray nozzle of the gas supply 80 and the ink bottle 20 is consistent, two fluid passage pressure balances in the channel system of sealing, ink 10 does not flow.In addition, air flue 62, air hose 70 and spray nozzle of the gas supply 80 sides can be flowed into, therefore air can be involved in owing to be trapped in the negative pressure material 120 interior inks 10 of print cartridge 100.In case be involved in air, then can produce bubble in air flue 62, air hose 70 or the spray nozzle of the gas supply 80.If contain bubble, then the deadweight meeting of ink 10 correspondingly reduces, and the liquid level of the ink 10 in the spray nozzle of the gas supply 80 can rise to the liquid level place of the ink 10 in a little higher than ink bottle 20, and ink 10 can't flow.The rise situation of the height that is equivalent to bubbles volume of the liquid level of the ink 10 in the air nozzle 80 is also included within the notion of liquid level when consistent.Thus, the ink 10 that inject specified quantitative just can prevent to inject the above ink 10 of specified quantitative to print cartridge 100 time.
Therefore, the injection rate of ink 10 can produce greatly influence to the position of nozzle insertion section 66 leading sections 68 of exhaust nozzle 60.Amount from inks 10 to print cartridge 100 that inject preferably ink 10 can fully be diffused into state negative pressure material 120 in, and can keep negative pressure material 120, does not inject the ink 10 more than this amount.That is to say, if the injection rate of ink 10 is when the amount that can keep negative pressure material 120 is above, when being installed to the printing equipment (not shown), the possibility that produces phenomenons such as ink overflows is very high, therefore the injection rate of preferred ink 10 is at this below boundary, and injects in large quantities.For this reason, the insertion position of the leading section 68 of nozzle insertion section 66 preferably is inserted in the negative pressure material 120 a little.If be positioned at negative pressure material 120 tops, the ink 10 that then surpasses the amount that can keep negative pressure material 120 is trapped on the negative pressure material 120, then, ink 10 begins to flow into air flue 62, air hose 70 and spray nozzle of the gas supply 80, thereby the injection rate that causes ink 10 is more than the amount that can keep negative pressure material 120.On the other hand, if it is dark excessively to be inserted into the degree of depth of negative pressure material 120, before ink 10 fully was diffused into negative pressure material 120, ink 10 can flow into air flue 62, air hose 70 and spray nozzle of the gas supply 80, causes the injection of ink 10 to stop.
In addition, ink injects pin 50 and preferably is inserted into negative pressure material 120 depths, ink 10 can be injected into the following position of negative pressure material 120, promptly the difference in height with the leading section 68 of nozzle insertion section 66 differs bigger position, after ink 10 diffusions, flow into air flue 62, air hose 70 and spray nozzle of the gas supply 80, thereby can inject a large amount of ink 10, but also can not be inserted into the depths.When the insertion depth that ink injects pin 50 is more shallow than exhaust nozzle front end 68, the ink 10 that injects is before being diffused into the bottom negative pressure material 120 of print cartridge 100, can arrive earlier in the groove 69 of exhaust nozzle 60, and then inflow air hose 70 and/or spray nozzle of the gas supply 80, when the height of the ink level of groove 69 in air hose 70 or spray nozzle of the gas supply 80 of the height of front end 52 that the ink in the print cartridge 100 injects pin 50 ink level in the ink bottle 20 and exhaust nozzle 60 reaches balance, stop to inject ink 10.In other words,, then be difficult to get rid of the air of negative pressure material 120 bottoms, might send out and to give full play to the original function of ink replenishing external member 1 if ink 10 is injected into negative pressure material 120 tops earlier.Therefore, the front end 52 that ink injects pin 50 preferably is inserted into the above position of certain depth, not device (not shown) such as contacted filter.Herein, certain depth can be different because of the difference of the shape of print cartridge 100, negative pressure material 120, in Fig. 1 or Fig. 2, be meant the degree of depth that is inserted into conscientiously above the uneven negative pressure material 120, the degree of depth more than 1/2nd of preferred print cartridge 100 height (interval between the formation face of the formation face of ink hand-hole 112 and ink supply port 102), the degree of depth that even more ideal is more than 3/4ths, especially good is near the formation face of ink supply port 102.
In addition, the preferred ink insertion position of injecting the insertion position of pin 50 and nozzle insertion section 66 away from.After inserting ink injection pin 50 and nozzle insertion section 66, negative pressure material 120 on every side correspondingly is expressed on one side, on every side compact.So, the capillary force rising of this part, the ink 10 that injects pin 50 injections from ink at first injected the diffusion on every side of pin 50 to ink before spreading in print cartridge 100.If being inserted into ink, nozzle insertion section 66 injects near the pin 50, then the ink 10 that injects from ink injection pin 50 can directly flow to the nozzle insertion section 66 big part of capillary force on every side from the ink injection pin 50 big part of capillary force on every side, before in print cartridge 100, fully spreading, ink 10 can flow into from the leading section 68 of nozzle insertion section 66, thereby stops to inject ink 10.Therefore, the interval between the insertion position of the insertion position of ink injection pin 50 and nozzle insertion section 66 is preferably as follows length: around separately, the scope of negative pressure material 120 compacts can not become one.This length is meant that ink injects the length-specific of the insertion position of pin 50 to the insertion position of nozzle insertion section 66.Because the factor differences such as material of negative pressure material 120, length-specific also can be different, for example, the height of negative pressure material 120 (measuring height of Fig. 1 above-below direction) is that 30mm, width (the measurement width of Fig. 1 left and right directions) are the print cartridge 100 of 55mm, at interval more than or equal to 10mm, be preferably greater than and equal 15mm.
If it is transparent that at least a portion of air hose 70 constitutes,, can confirm that then ink 10 flows into the state of air flue 62, air hose 70 and spray nozzle of the gas supply 80, so preferred this structure so that range estimation confirms to flow in ink 10 wherein.That is to say that if be full of ink 10 in the air hose 70, the injection that the user is easy to just to discern ink 10 finishes.
Next, with reference to Fig. 3, the preferable shape of leading section 68 of ink being injected the nozzle insertion section 66 of the leading section 52 of pin 50 and exhaust nozzle 60 describes.Fig. 3 is the front view that the explanation ink injects nozzle insertion section 66 leading sections, 68 structures of pin 50 leading sections 52 and exhaust nozzle 60, what Fig. 3 (a) represented is the leading section 52 that ink injects pin 50, and what Fig. 3 (b) represented is nozzle insertion section 66 leading sections 68 of exhaust nozzle 60.Shown in Fig. 3 (a), the leading section 52 that ink injects pin 50 is tilted cutting, so that be inserted in the negative pressure material 120 (with reference to Fig. 1), but in order to ensure safety, front end can be processed as flat condition or circle, guarantees that leading section 52 is not sharp.In addition, groove 54 begins to form certain depth from leading section 52.The hollow that ink injects pin 50 penetrates into leading section 52, but because ink injection pin 50 is thinner, when being inserted in the negative pressure material 120, negative pressure material 120 might stop up hollow.Therefore, form groove 54, under the blocked situation of the front end of hollow, can be used as ink channel.Groove 54 forms certain depth, so that can inject ink 10 (with reference to Fig. 1) by groove 54.So-called certain depth stopped up by negative pressure material 120 even be meant the front end of hollow, but the not blocked degree of depth in this degree of depth place for example, is 30mm if ink injects the length of pin 50 that then certain depth is meant the degree of depth about 3mm.Also can inject the leading section 52 position formation through hole in addition of pin 50 at ink, replace groove 54, be communicated with hollow and outside, but be preferably formed groove 54, because of its handling ease.The formation quantity of groove 54 without limits, and is common, and what ink injected pin 54 uses is steel detail empty needle, is typically and forms 1 or 2 grooves 54.
Shown in Fig. 3 (b), the shape of nozzle insertion section 66 leading sections 68 of exhaust nozzle 60 is also basic identical with the leading section 52 of ink injection pin 50, forms the groove 69 as air duct.But exhaust nozzle 60 is a plastics system, and it is thick that pin 50 is injected than ink in nozzle insertion section 66, therefore, normally makes exhaust nozzle 60 attenuation by number or the increase width that increases groove 69.Under the situation that is formed with groove 69, it is the degree of depth that ink 10 is detained the deep of groove 69 that ink 10 is detained the degree of depth (with reference to Fig. 2) in nozzle insertion section 66 leading sections 68 of exhaust nozzle 60.Identical with ink injection pin 50, also can form through hole and replace groove 69, as the air duct that leads to air flue 62.
Next, with reference to Fig. 1 and Fig. 4, the structure of the airport 34 that is used to inject ink is carried out more accurate explanation.Fig. 4 is the sectional view that is used to illustrate chimeric member 30, has check-valves 36 in the airport 34 of this chimeric member 30.During from spray nozzle of the gas supply 80 sides observation airport 34, airport 34 is spent in the thicker part office continuous bend 90 that embeds spray nozzle of the gas supply 80, and attenuates herein, and air hose 70 is connected to the part that attenuates.Check-valves 36 is set in such a way: in the position that begins to attenuate from thicker part step is set, this step as valve seat, is added a cover the taper portion of airport 34.Check-valves 36 can be plastics sheeting, and promptly so-called swing check-valves supports the top of check-valves 36 rotationally, if want to make air,, in print cartridge 100, reflux through air hose 70 from spray nozzle of the gas supply 80, check-valves 36 can be closed, stops flowing of air.On the other hand, check-valves 36 moves along the direction of arrow of Fig. 4, makes air from print cartridge 100, through spray nozzle of the gas supply 80, flows into ink bottle 20 (with reference to Fig. 1) and clog-free.
If check-valves 36 is set in airport 34, then can be by push, discharge the operation of ink bottle 20 repeatedly with hand, forcibly make the ink 10 in the ink bottle 20 inject pin 50, be injected in the print cartridge 100, and the air in the print cartridge 100 is sent in the ink bottle 20 by ink.That is to say, push ink bottle 20 with hand, then the increased pressure in the ink bottle 20 by the pressure of head difference generation and the pressure of pushing generation, is injected into ink 10 in the print cartridge 100 from ink bottle 20.Air by spray nozzle of the gas supply 80, airport 34, air hose 70 and exhaust nozzle 60 can utilize check-valves 36 to stop to flow.If stop to push, discharge ink bottle 20, for example the ink bottle 20 that is formed by polypropylene can elasticity revert to original form, and its inside becomes decompression state.Thereby can pass through exhaust nozzle 60, air hose 70, airport 34 and spray nozzle of the gas supply 80, from print cartridge 100 sucking-off air.Inject pin 50 etc. by ink, also can sucking-off ink 10, but since ink to inject pin 50 thinner, and the viscosity of ink 10 is greater than air, therefore a sucking-off air in fact.Ink replenishing external member 1 is installed on the print cartridge 100, when ink 10 begins to flow, because capillary effect, ink 10 might be difficult to flow, when this thing happens, in the manner described above, push ink bottle 20 with hand, forcibly make ink 10 begin to flow, this method is very effective.In addition, check-valves 36 need not to be arranged in the airport 34, can be arranged on the air duct any position of the air flue 62 of exhaust nozzle 60 to 80 of spray nozzle of the gas supply.
Then, with reference to Fig. 5, the variation that chimeric member 30 is described is chimeric member 130.Fig. 5 is the sectional view of the chimeric member 130 of explanation, and this chimeric member 130 is formed by rigid plastics, and is provided with spring valve 140.Chimeric member 130 is formed by for example polyformaldehyde etc.If form by rigid plastics, for airtight chimeric (comprising that liquid is close), and disposed O type ring 135 with the opening 22 (with reference to Fig. 1) of ink bottle 20, this point is different with situation about being formed by rubber etc., because rubber can produce strain.In addition, the ink discharge outlet 132 that embeds ink discharge nozzle 40 has also disposed O type ring 134.The connected mode of chimeric member 130 and air hose 70 is: make nozzle 136 outstanding, air hose 70 is embedded in the nozzle 136, this nozzle 136 is the effective fitting portions with chimeric member 136 one.If constitute in this manner, under the elastic reaction of air hose 70, air hose 70 is connected to nozzle 136 airtightly.The connected mode of chimeric member 130 and spray nozzle of the gas supply 80 makes as spray nozzle of the gas supply and gives prominence to the nozzle 138 of fitting portion too, and spray nozzle of the gas supply 80 is fitted in the nozzle 138.
Mode according to the ink discharge outlet 132 that covers chimeric member 130 is provided with spring valve 140.Spring valve 140 has spring support 142, spring 146 and valve plate 144, spring support 142 is by constituting from chimeric the member 130 a plurality of foots 141 on the side direction (with reference to Fig. 1) and flat board 143 of being supported by foot 141 in ink bottle 20, spring 146 is a disc spring, one end is fixed on the flat board of spring support 142, valve plate 144 is applied power towards ink discharge outlet 132 directions of chimeric member 130, and valve plate 144 covers ink discharge outlets 132.Valve plate 144 is covered ink discharge outlet 132 by spring 146 application of forces, thus closed ink discharge outlet 132.That is to say that ink 10 (with reference to Fig. 1) can't flow out from ink discharge outlet 132.But, by inserting ink discharge nozzle 40 to ink discharge outlet 132, fitting portion 44 makes the application of force of valve plate 144 antagonism springs 146, away from chimeric member 130, the ink via 42 (with reference to Fig. 1) of ink discharge nozzle 40 and the internal communication of ink bottle 20 (with reference to Fig. 1), ink 10 flows out.Because it is skewed that the front end of fitting portion 44 forms, so ink via 42 can be by valve plate 144 closures.
Because the structure of chimeric member 130 is: formed by rigid plastics, use O type ring 134,135 and air hose 70, spray nozzle of the gas supply 80 to connect airtightly, therefore, even cause air-tightness to reduce after long-time the use, also renewal part at an easy rate, thus air-tightness can be kept.In addition, owing to possess spring valve 140, therefore ink discharge nozzle 40 is not installed, ink 10 just can not flow out, thereby can prevent spilling of ink 10.In addition, the structure of spring valve 140 is not limited to structure shown in Figure 5, also can be other well-known valve cell, perhaps uses well-known closed cell to replace spring valve 140.
Then, with reference to Fig. 6, ink barrel 170 is described, ink barrel 170 is when the ink in the ink bottle 20 10 reduces, and makes the anchor clamps of the shower nozzle work of ink 10.Fig. 6 is the key diagram of ink barrel 170, what Fig. 6 (a) represented is not use under the situation of ink barrel 170, ink discharge nozzle 41 injects being connected of pin 50 with ink, Fig. 6 (b) expression be to inject connection when using ink barrel 170 between the pin 50 at ink discharge nozzle 41 and ink, what Fig. 6 (c) represented is that ink replenishing external member 1 is installed to the state of print cartridge 100 under the situation of using ink barrel 170.
Shown in Fig. 6 (a), the thin projection 49 of ink discharge nozzle 41 is 47 outstanding from the insertion section, and and is connected to ink to inject the lid 56 of pin 50 chimeric.That is to say that the external diameter of the internal diameter of lid 56 and projection 49 forms same size.In addition, the internal diameter of lid 56 has step, so that chimeric with ink hand-hole 112 (with reference to Fig. 1).Ink via 42 47 begins to extend to projection 49 from the insertion section, is formed with through hole in the lid 56, is communicated with the hollow that ink injects pin 50, and the hollow that the ink via 42 of ink discharge nozzle 41 and ink inject pin 50 is connected.
Shown in Fig. 6 (b),, joint 160 is connected to the projection 49 of ink discharge nozzle 41 in order to use ink barrel 170.Joint 160 is by strain and the chimeric airtightly pipe of projection 49, and its internal diameter size is identical with the external diameter of projection 49, thereby can be chimeric with projection 49.Ink barrel 170 is fitted on projection 49 opposition sides of joint 160.Ink barrel 170 is pipes that the external diameter of external diameter and projection 49 equates, is typically by rigid plastics to form.Because the external diameter of ink barrel 170 and the external diameter of projection 49 equate, therefore the lid 56 that is connected to ink injection pin 50 can be fitted to ink barrel 170.In this manner, inject configuration ink barrel 170 between the pin 50 at ink discharge nozzle 41 and ink.
Shown in Fig. 6 (c), use ink barrel 170, when print cartridge 100 injects ink 10, identical from ink replenishing external member 1 with situation shown in Figure 1, ink bottle 20, exhaust nozzle 60 etc. are installed.By using ink barrel 170, the interval of ink bottle 20 and print cartridge 100 is elongated.In addition, because air hose 70 has flexibility, therefore, even the interval of ink bottle 20 and print cartridge 100 is elongated, the connection of exhaust nozzle 60 and airport 34 (with reference to Fig. 1) and spray nozzle of the gas supply 80 still is easy to.Append ink barrel 170, raising ink bottle 20 is arranged on the height on the print cartridge 100, therefore, even if the amount of the ink 10 in the ink bottle 20 reduces, the pressure that difference in height the produced reduction of the liquid level of the ink 10 of the liquid level of the ink 10 in the ink bottle 20 in the print cartridge 100, but because rising, shower nozzle is equivalent to the height of ink barrel 170 length, so ink 10 still can flow to print cartridge 100 from ink bottle 20 at an easy rate.In addition, can prepare the ink barrel 170 of all lengths, the surplus according to the ink 10 in the ink bottle 20 changes employed ink barrel 170 to raise ink bottle 20.
At this,,, conclude explanation to the method that the print cartridge 100 that is filled with negative pressure material 120 replenishes ink 10 to above-described use ink replenishing external member 1 with reference to Fig. 1, Fig. 2 and Fig. 7.In addition, more than be to describe as example with the method that the ink replenishing external member 1 of using Figure 1 and Figure 2 is replenished ink 10, also can use other ink replenishing external member.Fig. 7 is that expression replenishes the flow chart of the method for ink 10 to print cartridge 100.At first, in print cartridge 100, relative with ink supply port 102 formation faces to face on form ink hand-hole 112 and steam vent 114 (step S10).The formation in hole 112,114 can be used (not shown) such as drill bit.Ink hand-hole 112 and steam vent 114 are separated, so that injected ink 10 that pin 50 injects before fully being diffused into negative pressure material 120 from ink, can not be sucked out from exhaust nozzle 60.Then, ink is injected pin 50 and be connected to the ink container 6 (step S20) of depositing ink 10.During connection, can between ink container 6 and ink injection pin 50, sandwich ink barrel 170 (with reference to Fig. 6).Next, exhaust nozzle 60 is connected to (step S30) in the ink container 6.Even directly connect exhaust nozzle 60 and ink container 6, also can insert air hose 70 and connection by between.Exhaust nozzle 60 by with being connected of ink container 6, and be connected with spray nozzle of the gas supply 80.In addition, spray nozzle of the gas supply 80 is communicated with the airport 34 of chimeric member 30 in advance, is fixed on the chimeric member 30.
According to above-described mode ink container 6 is set, begins to inject ink 10 then.Usually, can confirm that bubble flows, and confirms to begin to inject ink 10 in air hose 70 or spray nozzle of the gas supply 80 by range estimation.When beginning to inject ink 10,, can push ink container 6 (step S80) with hand if ink 10 is difficult to flow (step S70).Perhaps can temporarily open air intake passage 390 (with reference to Figure 10) etc.After ink 10 flowed, whether visual ink 10 flowed into air hose 70.If confirm to have in the air hose 70 ink 10 or ink 10 to flow, represent that then ink 10 fully is injected in the print cartridge 100, therefore, finish replenish (the step S90) of ink 10.In addition, even if former state is placed, ink 10 also can rise to spray nozzle of the gas supply 80 gradually, when ink container 6 in and in the liquid level pressure reduction in the print cartridge 100 and the spray nozzle of the gas supply 80 with print cartridge 100 in liquid level pressure reduction when equating, can stop to inject ink 10 automatically.Because the additional meeting of ink 10 finishes automatically, therefore can prevent to inject ink 10 above specified quantitative.In addition, each sequence of steps discussed above can change, and perhaps can carry out simultaneously.
Then, with reference to Fig. 8, the ink replenishing external member 201 of other type is described.Fig. 8 is that expression will be installed to the sectional view of the state on the print cartridge 100 as the ink replenishing external member 201 of the utility model second embodiment.Repeat specification is omitted in the aspect common with ink replenishing external member shown in Figure 11, and different aspects only is described.The side of (ink bottle 220 shown in Fig. 8 turns upside down, so the bottom among Fig. 8 is depicted in upside) is formed with air entry 292 near ink bottle 220 bottoms of ink container 206, and air intake duct 294 is connected to air entry 292.Dispose cock 296 in the air intake duct 294 as on-off valve.Air entry 292, air intake duct 294 and cock 296 constitute air intake passage 290.In addition, exhaust nozzle 260 is communicated with through air hose 70 and balance pipe 280.A front end of balance pipe 280 is that open end 284 is positioned at ullage space 14.Balance pipe 280 is the same with spray nozzle of the gas supply 80 (with reference to Fig. 1), is configured in the ink bottle 220, but also can be configured in outside the ink bottle 220, as long as its open end 284 is at the height place of ullage space more than 14.The height of ullage space more than 14 is meant the height that is higher than the liquid level of ink 10 in the ink bottle 220.Wherein, if balance pipe 280 is configured in the ink bottle 220, when the additional end of ink 10, when reverting to the opening 22 of ink bottle 220 up, the inks 10 that remain in the balance pipe 280 can turn back in the ink bottle 220, so preferably should dispose.
In the ink replenishing external member 201, the insertion section 248 of ink discharge nozzle 240 and the ink hand-hole 112 that is formed on the print cartridge 100 are chimeric airtightly.In addition, the nozzle insertion section 266 of exhaust nozzle 260 is chimeric airtightly with the steam vent 114 that is formed on the print cartridge 100.Seal ink hand-hole 112 and steam vent 114 airtightly, thereby the passage 42,50,62,70,280 that connects print cartridge 100, ink bottle 220 and these unit becomes airtight conditions.
As mentioned above, ink replenishing external member 201 is installed to print cartridge 100 after, open cock 296 utilizes air intake passage 290, and ullage space 14 and atmosphere in the ink bottle 220 are communicated with.So-called atmosphere is meant ink bottle 220 and print cartridge 100 space on every side.By ullage space 14 and atmosphere are communicated with, the pressure of ullage space 14 can be remained atmospheric pressure.Therefore, the ink 10 in the ink bottle 220 injects pin 50 from ink via 42 by ink, is injected in the print cartridge 100, and the air in the print cartridge 100 is sucked out by the air duct 62 of exhaust nozzle 260, through balance pipe 280, is sent in the ullage space 14.In addition, utilize vacuum condition, not sucking-off air, and pressurizeed to inhaling space (herein in the finger writing or painting box 100), thereby make air flow in the situation of the air duct 62 of exhaust nozzle 260, be also included within the notion of " sucking-off air ".
