With reference to figure 5B, when hollow tube 153 is inserted among the opening 51a via black exhaust openings 46a, moves with sweep 51c and separate with annular protrusion 51b thereby the tip of hollow tube 153 and spherical member 52 forms contact and spherical member 52.When this takes place; The state of first valve 50 is changed into open mode from closed condition, and in off position, first valve 50 prevents that the China ink among the black outlet pathway 43a from flowing via first valve 50; In open mode, first valve 50 allows the China ink among the black outlet pathway 43a to flow via first valve 50.Hollow tube 153 has the opening 153b through its formation, and the inner space 153a of hollow tube 153 is via the external communications of opening 153b and hollow tube 153.When first valve 50 is in open mode following time, the opening 153b of hollow tube 153 through opening 51a, makes the inner space 153a of hollow tube 153 and black outlet pathway 43a be interconnected via opening 153b.When hollow tube 153 moves when being drawn out opening 51a, spherical member 52 is because the bias voltage of helical spring 53 and moving towards annular protrusion 51b.When spherical member 52 contacted with annular protrusion 51b formation, the state of first valve 50 was changed into closed condition from open mode.When hollow tube 153 is moved further when being drawn out opening 51a, spherical member 52 forms tight the contact with sweep 51c.Correspondingly, first valve 50 is constructed to according to the insertion of hollow tube 153 and removes and optionally be under open mode and the closed condition.Because first valve 50 comprises the helical spring 53 towards seal member 51 bias voltage spherical members 52,, the structure of first valve 50 leaks from first valve 50 so being simplified and can preventing China ink.
With reference to figure 5A and 5B, second valve 60 is arranged on black outlet pathway 43a place, and is arranged between China ink bag 42 and first valve 50.Second valve 60 comprises: valve seat 61; Valve member 62 as second valve member; Helical spring 63 with the conduct that places black outlet pathway 43a second biasing member.Pipe 44 comprises along first direction and protrudes into the annular protrusion 44a the black outlet pathway 43a in pipe 44 pars intermedia office from managing 44 inner surface.Valve seat 61 by elastomeric material for example rubber etc. process, and comprise the annular protrusion 44a that is clipped in pipe 44 and manage the flange 61a between 45 the terrace part 45a.In another embodiment, valve seat 61 can be processed by inelastic materials fully.In yet another embodiment, valve seat 61 can save, and pipe 44 can be processed by inelastic materials fully.In such embodiment, valve member 62 can be configured to when the annular protrusion 44a of valve member 62 contact tubes 44, prevents that the China ink among the black outlet pathway 43a from flowing out through second valve 60.Valve seat 61 has the opening 61b through its formation, and opening 61b extends along first direction in the pars intermedia office of valve seat 61, makes the inside of pipe 44 and the inside of pipe 45 be interconnected to form black outlet pathway 43a.More specifically, the inside of pipe 44, the inside of pipe 45 and the opening 61b of valve seat 61 form black outlet pathway 43a.In other words, valve seat 61 has opening 61b, forms at least a portion of at least one sidewall that limits black outlet pathway 43a.In the illustrated embodiment, the cross section of valve seat 61 has shape basically.Yet in another embodiment, the cross section of valve seat 61 can have other shapes.In addition, in shown embodiment, valve seat 61 forms in pipe 44.Yet in another embodiment, valve seat 61 can be formed with one or two in pipe 44 and the pipe 45.Valve member 62 places the black outlet pathway 43a that is limited pipe 44 with helical spring 63, and each diameter less than the black outlet pathway 43a that is limited pipe 44 in the diameter of the diameter of valve member 62 and helical spring 63.
One end of helical spring 63 contacts with valve member 62, and the other end of helical spring 63 contacts with coupling part 42a.Helical spring 63 is constructed to consistently towards valve seat 61 and seal member 51 bias valve parts 62.Valve member 62 be constructed to when valve member 62 contact valve seats 61 around the part of opening 61b the time, prevent that the China ink among the black outlet pathway 43a from flowing via second valve 60, make the biasing force strain of said part through helical spring 63 of valve seat 61.When this took place, valve member 62 was under the closed condition, and in pipe 44 inside with manage fluid between 45 the inside and be communicated with and be able to prevent.The position of valve member 62 contact valve seats 61 limits the border between the first via path portion and the second path part, and first via path portion extends to said border from the outside of print cartridge 40, and the second path part extends to the inside of China ink bag 42 from said border.Because helical spring 63 is constructed to towards seal member 51 bias valve parts 62; And because first valve 50 and second valve 60 are that seal member 51, spherical member 52, helical spring 53, valve seat 61, valve member 62 and helical spring 63 are aimed on single straight line along first direction; So when hollow tube 153 is inserted into seal member 51 neutralization when being drawn out seal member 51 along first direction/principal direction, first valve 50 and second valve 60 can be opened and closed.Second valve 60 can utilize simple structure to process, thereby reduces the opening/closing fault of second valve 60.In this embodiment, helical spring 63 is used as biasing member, but as long as valve member 62 can be used the biasing member except helical spring by towards valve seat 61 bias voltages.
Valve member 62 has cylindrical shape, and is constructed on the inner surface of pipe 44, slide.First end of facing with coupling part 42a of valve member 62 has therebetween the part place along the protrusion shape of first direction protrusion.Helical spring 63 is around the projection assembling of valve member 62.Valve member 62 has along the width of the direction vertical with first direction.The width of valve member 62 is greater than first width of first via path portion, for example greater than the inner width of at least a portion of the pipe 45 shown in Fig. 5 A and Fig. 5 B.And the width of valve member 62 for example less than the inner width of pipe 44, makes that China ink can flow through managing 44 when valve member 62 separates with valve seat 61 less than second width of the second path part.The width of valve member 62 is defined as mean breadth.In another embodiment, the width of valve member 62 is defined as the width of the part of contact valve seat 61.And second width of the second path part is defined as mean breadth, but in another embodiment, the boundary definition of second width of the second path part between the first via path portion and the second path part.
Extruder member 70 places black outlet 43, is constructed to along pushing and movement of valve parts 62 with the direction in the opposite direction of helical spring 63 bias valve parts 62.Extruder member 70 is cylindrical rod that the opening 61b through valve seat 61 extends along first direction.Extruder member 70 is connected to second end of valve member 62 and is integral with valve member 62.Extruder member 70 has the diameter less than the diameter of opening 61b.The length that extruder member 70 has makes: when second valve 60 is under the closed condition (valve member 62 contact valve seats 61); When the state of first valve 50 when open mode is changed into closed condition (when spherical member 52 when seal member 51 moves with contact annular protrusion 51b), between the tip of extruder member 70 and spherical member 52, form the gap.
With reference to figure 5B, be inserted into through seal member 51 and after first valve 50 became open mode, spherical member 52 formed with the tip of extruder member 70 and contacts at hollow tube 153.When hollow tube 153 was further inserted, extruder member 70 moved with valve member 62, and when hollow tube 153 through seal member 51 be inserted into scheduled volume apart from the time, valve member 62 is removed from valve seat 61.Correspondingly, the state of second valve 60 is changed into the open mode that second valve 60 allows the China ink the black outlet pathway 43a to flow via second valve 60 from closed condition.When this took place, the inside of the inside of pipe 44 and the pipe 45 of black outlet pathway 43a formed fluid and is communicated with, and made that the China ink of storage flows among the inner space 153a of hollow tube 153 in China ink bag 42.When hollow tube 153 was drawn out seal member 51, valve member 62 moved towards valve seat 61 owing to the bias voltage of helical spring 63 with extruder member 70, and valve member 62 closely contacts with valve seat 61 formation.Correspondingly, the state of second valve 60 is changed into closed condition from open mode.Therefore; Second valve 60 also is constructed to optionally be in open mode and closed condition, and in open mode, second valve 60 allows the China ink among the black outlet pathway 43a to flow via second valve 60; In off position, second valve 60 prevents that the China ink among the black outlet pathway 43a from flowing via second valve 60.
With reference to figure 6A and 6B, ink-jet printer 1 comprises four mounting portions 150 of arranging along auxiliary direction, and said four print cartridges 40 are respectively installed to said four mounting portions 150.Because mounting portion 150 has essentially identical structure, so will describe a mounting portion 150.
Mounting portion 150 has the recess 151 that forms therein, and recess 151 has the shape corresponding to the profile of print cartridge 40.Hollow tube 153 is located at and is limited the base portion part 151a place of recess 151 along the end of auxiliary direction.China ink feed lines 154 forms in base portion part 151a and is communicated with the inner track fluid of the flexible pipe that is connected to ink gun 2.
Hollow tube 153 extends along principal direction, and places when print cartridge 40 is installed to mounting portion 150 position corresponding to opening 51a.Hollow tube 153 has therein the inner space 153a that forms, is communicated with black feed lines 154 fluids, and has the external communications (seeing Fig. 5 A and Fig. 5 B) with permission inner space 153a and hollow tube 153 near the opening 153b of its tip through its formation.Be inserted into when making in the seal member 51 that opening 153b gets into the black outlet pathway 43a that is limited pipe 45 through opening 51a when print cartridge 40 is installed to mounting portion 150 and hollow tube 153, the inner space 153a of hollow tube 153 and black outlet pathway 43a form the fluid connection via opening 153b.When print cartridge 40 150 is removed and hollow tube 153 when being drawn out seal member 51 and making that opening 153b gets into opening 51a from the mounting portion, the fluid between the inner space of hollow tube 153 153a and black outlet pathway 43a is communicated with and is blocked.Even if the inner space 153a of hollow tube 153 is communicated with black outlet pathway 43a via opening 153b, the China ink of storage does not flow among the 153a of inner space yet in China ink bag 42, becomes open mode until second valve 60.
With reference to figure 7A-7D, described at print cartridge 40 and how to have worked to first valve 50 between the installation period of mounting portion and second valve 60.Dotted line S1 shown in Fig. 7 A-7E be expression when spherical member 52 and sweep 51c contact in the end of spherical member 52 and the boundary line on the border between the sweep 51c, this end is along first direction distance second valve 60 (left end of the spherical member 52 among Fig. 7 A-7E) farthest.Dotted line S2 is the boundary line that the state of first valve 50 when spherical member 52 moves changes between open mode and closed condition.To be expression contact with valve member 62 during in strain and the boundary line on extruder member 70 border between valve seat 61 and valve member 62 when not contacting with spherical member 52 when valve seat 61 dotted line S3.Dotted line S4 is the boundary line that the state of second valve 60 when valve member 62 moves changes between open mode and closed condition.
With reference to figure 7A, when hollow tube 153 is not inserted in the black outlet 43, that is, when print cartridge 40 was not installed to mounting portion 150, only the biasing force of helical spring 53 was applied to spherical member 52, and (left side) end of spherical member 52 is positioned on the S1 of boundary line.In other words, first valve 50 is under the closed condition, and spherical member 52 contacts with sweep 51c and annular protrusion 51b.
When expectation is installed to mounting portion 150 with print cartridge 40, opens the door 1c of ink-jet printer 1, and print cartridge 40 is installed to corresponding in the mounting portion 150 via opening 10c.When hollow tube 153 is inserted among the opening 51a, the tip of hollow tube 153 and spherical member 52 form contact and spherical member 52 mobile, as shown in fig. 7b towards second valve 60 (in Fig. 7 A-7E to the right).When the crossing the boundary line S2 of (left side) end of spherical member 52, spherical member 52 separates with seal member 51, and the state of first valve 50 is changed into open mode from closed condition.Therefore, when spherical member 52 from the state of spherical member 52 contact sweep 51c be moved beyond between boundary line S1 and S2 apart from the time, first valve 50 becomes open mode.During when (left side) end of spherical member 52 is between boundary line S1 and S2, spherical member 52 contacts with annular protrusion 51b, and the valve 50 of winning is maintained under the closed condition.When the state of first valve 50 is transformed into open mode, still between spherical member 52 and extruder member 70, form the gap.Therefore only the biasing force of helical spring 63 is applied to valve member 62; Make the end of valve member 62 be positioned on the S3 of boundary line; This end is farthest end (left end of valve member 62 in Fig. 7 A-7E) along first direction apart from coupling part 42a, and second valve 60 is maintained under the closed condition.When second valve 60 is in closed condition following time, the part of facing with valve member 62 (right half of valve seat 61 in Fig. 7 A-7E) of valve seat 61 is contacting with valve member 62 during (by along the bias voltage direction compression of helical spring 63 time) strain because the biasing force of helical spring 63.
With reference to figure 7C, when hollow tube 153 was further inserted, the tip of spherical member 52 and extruder member 70 formed and contact, and spherical member 52, extruder member 70 and valve member 62 are mobile towards coupling part 42a (in Fig. 7 A-7E to the right).When the crossing the boundary line S4 of (left side) end of valve member 62, valve member 62 separates with valve seat 61, and the state of second valve 60 is changed into open mode from closed condition.Therefore, when valve member 62 from boundary line S3 be moved beyond between boundary line S3 and S4 apart from the time, second valve 60 becomes open mode.During when (left side) end of valve member 62 is between boundary line S3 and S4, valve member 62 contacts with valve seat 61, makes second valve 60 be maintained under the closed condition.Distance between boundary line S3 and S4 is the elastically deformable scope of valve seat 61.
With reference to figure 7D, hollow tube 153 is further inserted until accomplishing the installation of print cartridge 40 to mounting portion 150, and hollow tube 153 is inserted into scheduled volume and when accomplishing installation, stops.Therefore, the state of each in first valve 50 and second valve 60 according to hollow tube 153 in the black outlet pathway 43a insertion and change into open mode from closed condition, thereby after first valve 50 became open mode, second valve 60 became open mode.Therefore, the China ink of storage flows among the inner space 153a of hollow tube 153 in mounted print cartridge 40, and China ink is fed to ink gun 2 from print cartridge 40 thus.
With reference to figure 7E, described during removing print cartridge 40 first valve 50 and second valve 60 and how to have worked from mounting portion 150.For example when China ink when being used up, print cartridge 40 150 is removed from the mounting portion.According to from the mounting portion 150 remove print cartridge 40 motion (being drawn out the motion of black outlet 43 according to hollow tube 153); Because helical spring 53 and 63 biasing force, spherical member 52, valve member 62 and extruder member 70 move on the direction of leaving coupling part 42a (in Fig. 7 E left) when being in contact with one another together.In other words, spherical member 52, extruder member 70 and valve member 62 move along the direction in the opposite direction that they move when being inserted in the seal member 51 when hollow tube 153.When (left side) end of valve member 62 arrived boundary line S4, valve member 62 formed with valve seat 61 and contacts, and the state of second valve 60 is changed into closed condition from open mode.When this took place, China ink stopped to flow to from China ink bag 42 the inner space 153a of hollow tube 153.
Subsequently, valve member 62 moves until (left side) end of valve member 62 with extruder member 70 and arrives boundary line S3.When (left side) end of valve member 62 arrived boundary line S3, the motion of valve member 62 and extruder member 70 stopped.And then, only spherical member 52 moves with hollow tube 153, makes the tip of spherical member 52 and extruder member 70 be separated from each other.When (left side) end of spherical member 52 arrived boundary line S2, spherical member 52 formed with annular protrusion 51b and contacts, and the state of first valve 50 is changed into closed condition from open mode.Subsequently, spherical member 52 moves until (left side) end of spherical member 52 and arrives boundary line S1.Therefore, be drawn out the motion of seal member 51 according to hollow tube 153, the state of each in first valve 50 and second valve 60 is changed into closed condition from open mode.After second valve 60 became closed condition, first valve 50 became closed condition.In this way, old print cartridge 40 105 is removed from the mounting portion, and new print cartridge 40 is installed to mounting portion 105.The elastic modelling quantity of helical spring 63 is confirmed as and can applies biasing force to valve member 62; This power surpasses the power that when impact is applied to valve member 62, produces, and makes when the user handles print cartridge 40, will in second valve 60, not form any gap that possibly cause ink leakage owing to impacting.And, because valve member 62 by helical spring 63 consistently towards valve seat 61 bias voltages, so when print cartridge 40 keeps not being used (when print cartridge 40 by from the mounting portion 150 when removing), second valve 60 is maintained under the closed condition consistently.
As stated; In print cartridge 40 according to this embodiment; When hollow tube 153 was inserted in the seal member 51, first valve 50 became open mode, and hollow tube 153 moves spherical member 52, extruder member 70 and valve member 62 then; Make valve member 62 remove from valve seat 61, this causes that second valve 60 becomes open mode.When hollow tube 153 was drawn out seal member 51, second valve 60 became closed condition, and first valve 50 becomes closed condition then.Correspondingly, be completely pulled out of the instantaneous of seal member 51 at hollow tube 153, second valve 60 has been under the closed condition.Therefore, when hollow tube 153 is drawn out first valve 50 and after hollow tube 153 is drawn out first valve 50 and when first valve 50, be in closed condition following time,, also can reduce a large amount of leakages of China ink even if first valve 50 is damaged.
According to first variant embodiment of the present invention, compare annular protrusion 51b with first embodiment and have longer size along first direction.Therefore; In first embodiment,, first valve 50 between spherical member 52 and extruder member 70, formed the gap when becoming open mode; But in this first variant embodiment; Spherical member 52 forms with extruder member 70 and contacts before first valve 50 becomes open mode, does not form between spherical member 52 and extruder member 70 and there is the gap.
With reference to figure 8A and 8B, in this first variant embodiment, compare for the location of boundary line S3 with boundary line S2, boundary line S2 ' locatees near boundary line S3 more.In this case; With reference to figure 8A, when hollow tube 153 is inserted in the black outlet 43 and the tip of spherical member 52 and extruder member 70 forms when contacting, (left side) end of spherical member 52 is not through boundary line S2 '; That is, first valve 50 still maintains under the closed condition.Annular protrusion 51b has such length, make spherical member 52 and extruder member 70 form contact after still before second valve 60 becomes open mode, first valve 50 becomes open mode.With reference to figure 8B, when (left side) end of spherical member 52 arrives boundary line S2 ' time, (left side) end of valve member 62 is between boundary line S3 and S4.
Apart from T1 less than apart from T2; Apart from T1 is the distance that moves to the time spherical member 52 when first valve 50 becomes open mode from the time that forms when spherical member 52 and extruder member 70 when contact, the distance that moves from the time valve parts 62 of time of (when valve member 62 (left side) end is positioned at boundary line S3) when spherical member 52 and extruder member 70 formation contact during extremely as (left side) end of valve member 62 arrival boundary line S4 apart from T2.Correspondingly, in this first variant embodiment, between the installation period of mounting portion 150, after first valve 50 became open mode, second valve 60 became open mode at print cartridge 40 equally.During removing print cartridge 40 from mounting portion 150, after second valve 60 became closed condition, first valve 50 became closed condition.Correspondingly, can obtain the advantage identical with first embodiment.
In above-mentioned first variant embodiment, compare annular protrusion 51b with first embodiment and have longer size along first direction.In another embodiment, compare with first embodiment and to make extruder member longer, to substitute annular protrusion 51b with longer size along first direction.In this situation; Extruder member has such length; Make: the time when contact from forming when spherical member 52 and extruder member is the distance that moves of the time spherical member 52 when first valve 50 becomes open mode extremely, less than from the distance that moves of the time valve parts 62 when second valve 60 becomes open mode extremely of the time when spherical member 52 and extruder member formation contact.
With reference to figure 9A and 9B, according to second variant embodiment of the present invention, extruder member 270 is integral with spherical member 52.With reference to figure 9A, extruder member 270 comprises the annular protrusion 271 that the outer surface faced mutually from the inner surface with helical spring 53 of extruder member 270 extends, and annular protrusion 271 plays the effect of the guiding piece of the motion that is used for extruder member 270 and spherical member 52.Correspondingly, with reference to figure 9B, extruder member 270 can move according to the motion of spherical member 52 inner surface along helical spring 53.And; Because extruder member 270 is not integral with valve member 62, so (left side) end valve member 62, that be constructed to contact valve seat 61 can be easy to by with high precision manufacturing, for example; Grinding or polishing are stabilized in the close contact between valve member 62 and the valve seat 61 thus.On the other hand; In above-mentioned first embodiment, because extruder member 70 is not integral with spherical member 52 but separates with spherical member 52, so as comparing with second variant embodiment; Extruder member 70 can be easy to make, and therefore operates with stable manner.
In this second variant embodiment; The gap that when sweep 51c and spherical member 52 contacts, between extruder member 270 and valve member 62, forms; Compare with the gap that in first embodiment, when sweep 51c and spherical member 52 contact, between spherical member 52 and extruder member 70, forms, have identical size along first direction.Correspondingly, compare with first embodiment, the moment of the state of first valve 50 when the state of the change and second valve 60 between open mode and the closed condition changes between open mode and closed condition is identical.Therefore, in this second variant embodiment, can obtain the advantage identical with first embodiment.
With reference to figure 10A and 10B; According to the 3rd variant embodiment of the present invention, extruder member 370 neither is integral also with spherical member 52 and is not integral with valve member 62, promptly; The extruder member 370 and first valve 50 and second valve were opened in 60 minutes, and placed between spherical member 52 and the valve member 62.Correspondingly, be similar to second variant embodiment, (left side) end that being constructed to of valve member 62 contacts valve seat 61 can be easy to by with high precision manufacturing, and for example, grinding or polishing are stabilized in the close contact between valve member 62 and the valve seat 61 thus.In addition, extruder member 370 separates with spherical member 52, can be easy to make thereby be similar to the first embodiment extruder member 370.With reference to figure 10A, extruder member 370 comprises the annular protrusion 371 and 372 that the outer surface faced mutually from the inner surface with helical spring 53 of extruder member 370 extends, and annular protrusion 371 and 372 plays the effect of the guiding piece of the motion that is used for extruder member 370.Therefore, according to the motion of spherical member 52 and the motion of valve member 62, extruder member 370 can move along the inner surface of helical spring 53, as shown in Fig. 10 B.
In this 3rd variant embodiment; When 52 contacts of sweep 51c and spherical member along first direction between extruder member 370 and the spherical member 52 and the overall dimension in two gaps that between spherical member 52 and valve member 62, form, with in first embodiment when sweep 51c and spherical member 52 contact measure-alike along gap that first direction forms between spherical member 52 and extruder member 70.Correspondingly, the state of first valve 50 is changing between open mode and the closed condition and the state of second valve 60 moment when between open mode and closed condition, changing identical with in first embodiment.Therefore, in this second variant embodiment, can obtain the advantage identical with first embodiment.
