In addition, the front surface view of framework 100 is different owing to the position of the pouring ink hole 121 that is connected with refilling part 130 with the rear surface view.As shown in the rearview of the framework 100 in Fig. 7 (b), pouring ink hole 121 does not appear in the ink storage area 120.That is to say that 121 of pouring ink holes are formed on the side (the front view side of Fig. 7 (a)) of framework 100, so ink injects from a position.
Shown in Fig. 7 (a) and 7 (b), chassis body part 110 forms as the general square shape shape of seeing from the direction vertical with paper, and is formed with four frame edge parts 112 at the place, bight.Shown in Fig. 7 (a) and 7 (b), on the front side and rear side of framework 100, those two apertures 125 of frame edge part 112 contact ink storage areas 120, and be arranged to pair of flanges, this extends to the outside of the framework haunched member 111 that surrounds these apertures 125 to flange.Each frame edge part 112 according to as Fig. 8 (c) and the mode that clips refilling part 130 and ink guide part 140 (d) form tabular.In addition, as Fig. 8 (c) with (d), framework haunched member 111 is respectively formed at that on the frame edge part 112.When being welded on film 1430 on the framework haunched member 111, pair of frames marginal portion 112 becomes the receiving surface of film 1430.In addition, pair of frames restricted part 150 is arranged to be connected with frame edge part 112.Frame edge part 112 forms thin sheet form, and is formed with a space between forward and backward frame edge part 112, thereby a little less than making these frame edge parts 112.In order to keep the intensity of frame edge part 112, be formed with framework rib member 410,420,430,440,450,460,470,480 and 490.Below frame rib bar member 410-490 is described.
Shown in Fig. 8 (c), framework rib member 410,420,430 and 440 (first strengthens rib) is formed between the pair of frames marginal portion 112, so that by connecting that keeps frame edge part 112 to frame edge part 112 intensity.As shown in Figure 9, framework rib member 410 is arranged near an end of the horizontal direction of chassis body part 110.Shown in Fig. 8 (c), framework rib member 410 forms tabular.Shown in Fig. 8 (a), on the vertical direction (vertical direction of Fig. 8 (a)) of framework 100, framework rib member 410 forms from extending to the centre position on chassis body part 110 near the upper end of chassis body part 110.
According to the mode identical with framework rib member 410, in the centre of chassis body part 110 along horizontal direction, framework rib member 430 is formed extended at both sides along vertical direction from the outward flange of the upper end side of chassis body part 110 and is tabular.As shown in Figure 9, determine the length of framework rib member 430 according to the mode identical with the length of definite framework rib member 420.
As shown in Figure 9, near framework rib member 440 is arranged in relative end, the end with being provided with framework rib member 410 of chassis body part 110 along horizontal direction.According to the mode identical with framework rib member 420, framework rib member 440 comprises the rib cylindrical part 441 of substantial cylindrical and a pair of rib jut 442 that stretches out from rib cylindrical part 441 towards frame edge part 112.Shown in Fig. 8 (b), framework rib member 440 forms from extending to the centre position along vertical direction (vertical direction of Fig. 8 (b)) of framework 100 near the upper end of chassis body part 100.
In addition, shown in Fig. 8 (c), on the horizontal direction of chassis body part 110, refilling part 130 is vertically extended between framework rib member 430 and framework rib member 440.Refilling part 130 is also as the framework rib member, because the part of the outer surface of refilling part 130 is connected frame edge part 112 with that.
Shown in Fig. 8 (d), between frame edge part 112, be formed with framework rib member 450,460,470 and 480 (first strengthens rib), they have kept the intensity of frame edge part 112.Framework rib member 450 comprises rib cylindrical part 451 that forms the substantial cylindrical shape and a pair of rib haunched member 452 that stretches out from rib cylindrical part 451 towards frame edge part 112.As shown in Figure 9, framework rib member 450 is formed near the end of horizontal direction of chassis body part 110.Shown in Fig. 8 (a), framework rib member 450 forms along vertical direction (vertical direction of Fig. 8 (a)) from extending to the centre position of framework 100 near the lower end of chassis body part 110.
According to the mode identical with framework rib member 450, framework rib member 460 comprises the rib cylindrical part 461 of substantial cylindrical and a pair of rib jut 462 that stretches out from rib cylindrical part 461 towards frame edge part 112.As shown in Figure 9, near framework rib member 460 forms and extends to ink storage area 120 from the outer rim of the lower end side of chassis body part 110 along vertical direction.On the horizontal direction of chassis body part 110, framework rib member 460 is formed on the centre of chassis body part 110.Because the height of frame edge part 112 is less at the position that is formed with framework rib member 460, so the height of this framework rib member 460 is also less.
In addition, as Fig. 8 (d) and shown in Figure 9, on the horizontal direction of chassis body part 110, cylindrical ink part 140 is vertically extended between framework rib member 450 and 460.This ink guide part 140 is as the framework rib member, because the part of its outer surface contacts that to frame edge part 112.
In addition, as Fig. 8 (a) with (b), in chassis body part 110 in the centre position of vertical direction, that to framework rib member 490 (second strengthen rib) form make framework rib member 410 and 450 and framework rib member 440 and 480 interconnect respectively.As shown in Figure 9, on identical straight line, that forms the side outer rim (end along horizontal direction of chassis body part 110) that extends to chassis body part 110 from ink storage area 120 along the direction vertical with framework rib member 410-480 to framework rib member 490.
In addition, shown in Fig. 7 and Fig. 8 (d), framework restricted part 150 forms respectively stretches out frame edge part 112 from that, and framework restricted part 150 is arranged in parallel to each other.That to the interval between the framework restricted part 150 with appear at that to be formed at block those in 300 consistent to the interval between the block limiting member 370.
In exemplary, chassis body part 110 is formed by resin material, and uses metal die to carry out molded.For example, by using framework rib member 490, prepare and framework rib member 410-440 side and two corresponding different metal dies of framework rib member 450-480 side as the border.Under these two interconnective states of metal die, liquid state (or semi liquid state) resin is injected in the metal mold, and is molded into chassis body part 110 by resin is cooled off.Therefore, the resin that is injected in the gap that is formed between these two metal dies under two interconnective states of metal die forms that to framework rib member 490.After making the resin material sclerosis, by metal die is promptly moved along vertical direction (vertical direction of Fig. 8 (b)) along the direction that two metal dies are separated from each other, thereby take off molded good chassis body part 110 from metal die, and framework rib member 410-480, refilling part 130 and ink guide part 140 form along vertical direction and extend.Therefore, can not hinder metal die under the situation of moving of vertical direction, to be easy to take off chassis body part 110.
Therefore, have only that framework rib member 490 is formed along horizontal direction and extend, and other framework rib member 410-480, refilling part 130 and ink guide part 140 are arranged to extend along vertical direction.Therefore, be used for strengthening those many members to frame edge part 112 though be provided with, chassis body part 110 can be molded in the simplification metallic type structure that is formed by two metal dies.Therefore the reinforcement that can implementation framework marginal portion 112 and the cost of metal die reduce.
In addition, rib cylindrical part 421,441,451 and 461 also is used as the receiving unit that is promoted by stripper pin when taking off chassis body part 110 from metal mold.
Therefore, as mentioned above, frame edge part 112 forms writing board shape, thus make frame edge part 112 structurally a little less than.But, by framework rib member 410-490 is provided, thereby can improve the intensity of frame edge part 112.Therefore, strengthened chassis body part 110.As described below, by on the frame edge part 112 that film 1430 is pressed against chassis body part 110 film 1430 (referring to Figure 19) being welded on the chassis body part 110.Therefore, if 112 bendings of frame edge part, then this film 1430 can not accurately weld.In addition, chassis body part 110 can be impaired.But as shown in Figure 9, framework rib member 410-490 forms and is roughly extending on the whole chassis body part 110, therefore can prevent the damage to chassis body part 110, and can prevent frame edge part 112 bending when welding film 1430.
In addition, the central axis of refilling part as shown in Figure 9,130 and the central axis of ink guide part 140 are parallel with the center line (through the straight line of framework rib member 430 and framework rib member 460) of the ink storage area 120 (chassis body part 110) of chassis body part 110 in the position of horizontal direction (horizontal direction of Fig. 9) disalignment.In the time of on the center line that refilling part 130 and ink guide part 140 is arranged on ink storage area 120, ink storage area 120 must form the circular shape, so ink storage area 120 becomes big from chassis body part 110 outwardly directed distances.Therefore, it is big that the size of chassis body part 110 becomes, and print cartridge 1 becomes big.But, when refilling part 130 and ink guide part 140 are formed in the position of the center line that departs from ink storage area 120, can make print cartridge 1 less.
In addition, when ink storage area 120 forms the substantially elliptical shape, can make print cartridge 1 less according to as above identical mode.

Figure 12 demonstrates joint member 610.Figure 12 (a) is the side view of this joint member 610, and Figure 12 (b) is the top view of this joint member 610, and Figure 12 (c) is the bottom view of this joint member 610, and Figure 12 (d) is the cutaway view in the joint member 610 shown in Figure 12 (b).
Shown in Figure 12 (a), joint member 610 in side view (from the vertical direction of paper of Figure 12 (a)) comprise three layers.Orlop part (downside of Figure 12 (a)) is the joint outer peripheral portion 710 of the outer peripheral portion of formation joint member 610.This joint outer peripheral portion 710 goes out to the outer exposed of ink guide part 140.Part above this joint outer peripheral portion 710 is circumferential portion 720 in the joint of the interior circumferential portion of formation joint member 610.Circumferential portion 720 is arranged in ink guide part 140 inside in this joint.That part of joint contact portion 730 that in joint, demonstrates above the circumferential portion 720 for contact valve member 620.Shown in Figure 12 (b), the axle center of circumferential portion 720 and joint contact portion 730 is arranged on the axle center identical with the axis B of valve system 530 in joint outer peripheral portion 710, the joint.In addition, for example resin or rubber form joint member 610 by elastomeric material.
Shown in Figure 12 (d), between the circumferential portion 720, being formed with cross section is the joint trench portions 740 of spill in joint outer peripheral portion 710 and joint.Shown in Figure 12 (b), this joint trench portions 740 forms round-shaped in plane.This joint trench portions engages with the bottom of the periphery wall of the ink guide part 140 that forms cylinder form, and joint member 610 is fixed on the ink guide part 140.Shown in Figure 12 (d), joint contact portion 730 end face 731 (on the surface that is contacting on that side of valve member 620) of circumferential portion 720 in the joint stretches out.Joint contact portion 730 forms towards top ends 734 (to the end of the upside of Figure 12 (d)) and narrows down.The bottom surface of top ends 734 contact valve members 620, and close black flow channel.In addition, in joint in the circumferential portion 720, joint jut 750 stretches out towards axis B from interior perimeter surface 733, be formed with the aperture 722 that becomes the insertion mouth that is used for pumping ink pipe 1720 (referring to Figure 26) on the bottom surface 721 of circumferential portion 720 in joint (downside of Figure 12 (d)), and between aperture 722 and joint jut 750, be formed with conical surface 723.
In addition, shown in Figure 12 (d), in joint member 610, be formed with black flow channel 760, its bottom surface 721 of circumferential portion 720 in the joint extends through the top ends 734 (upside of Figure 12 (d)) of joint contact portion 730.This China ink flow channel 760 comprises the aperture 722 that is formed in the bottom surface 721, the tapering part flow channel 761 that forms by the conical surface 723 that is connected with aperture 722, the jut flow channel 762 that forms by the interior perimeter surface 751 of the joint jut 750 that is connected with conical surface 723, the contact portion flow channel 763 that forms by the stepped surfaces 732 that is connected with the interior perimeter surface 751 of joint jut 750, and the interior perimeter surface 733 of the joint contact portion 730 that is connected with stepped surfaces 732.In addition, the interior perimeter surface 751 of joint jut 750 is parallel with axis B, and stepped surfaces 732 is vertical with axis B.
Tapering part flow channel 761 forms the general hollow coniform shape, and wherein diameter 722 diminishes towards the contact point with the interior perimeter surface 751 of joint jut 750 gradually from the aperture.This jut flow channel 762 forms the general hollow cylinder form, and it has the internal diameter identical with the minimum diameter of tapering part flow channel 761.The internal diameter of jut flow channel 762 forms slightly littler than the diameter of pumping ink pipe (referring to Figure 26).Contact portion flow channel 763 forms the general hollow cylinder form, and its internal diameter is greater than the internal diameter of jut flow channel 762, and this internal diameter is greater than the diameter of pumping ink pipe.In addition, be formed with stepped surfaces 732 in the border between jut flow channel 762 and contact portion flow channel 763.Therefore, internal diameter changes rapidly to contact portion flow channel 763 along axis B direction from jut flow channel 762.Therefore, shown in Figure 12 (d), joint contact portion 730 has by the structure that become base shape of interior perimeter surface 733 with stepped surfaces 732 otch, and the top ends 734 of joint contact portion 730 is provided with round this notch portion.
Pumping ink pipe 1720 is inserted in the aperture 722 by conical surface 723 guiding of tapering part flow channel 761, and is inserted in the jut flow channel 762.As mentioned above, the internal diameter of jut flow channel 762 is slightly smaller than the diameter of pumping ink pipe 1720, so pumping ink pipe 1720 elastic attachment are on the interior perimeter surface 751 of the joint jut 750 that forms jut flow channel 762.That is to say that joint jut 750 is used for surrounding the pumping ink pipe 1720 that is inserted into jut flow channel 762.If the area of the elastic attachment of joint member 610 on the periphery of pumping ink pipe 1720 is too big, resistance will increase in the time of then on print cartridge 1 being installed in ink-jet printer 1710 (referring to Figure 26), and can not realize level and smooth installation.But in the embodiment shown in for example Figure 12 (d), joint jut 750 is arranged such that pumping ink pipe 1720 is just contacting interior perimeter surface 751.Therefore, by allowing joint member 610 have the very little area that contacts with pumping ink pipe 1720, thereby can carry out smoothly print cartridge 1 is installed on the ink-jet printer 1710.For black flow channel 760, when inserting pumping ink pipe 1720, the flow channel of ink actual flow is positioned at the inside of pumping ink pipe 1720.In addition, as described below, by contact portion flow channel 763 is formed base shape, thereby when inserting pumping ink pipe 1720, joint member 610 is minimized along the displacement of axis B direction.
Figure 13 demonstrates valve member 620.Figure 13 (a) is the front view/rearview of valve member 620, Figure 13 (b) is the side view of valve member 620, Figure 13 (c) is the top view of valve member 620, and Figure 13 (d) is the bottom view of valve member 620, and Figure 13 (e) is the cutaway view at the valve member 620 shown in Figure 13 (c).
Shown in Figure 13 (a), the valve sidewall 820 that valve member 620 is provided with the valve diapire 810 of the bottom surface (surface at the downside place in Figure 13 (a)) that forms valve member 620 and extends from valve diapire 810 along axis B direction.In valve sidewall 820, be formed with a pair of valve guide groove 830, wherein can insert the loose insertion member 1030 of slide block (referring to Figure 15) of slider component 640 loosely.Shown in Figure 13 (c), that is symmetrically formed the axis B of valve guide groove 830 with respect to valve system 530.In addition, shown in Figure 13 (a), that forms along whole valve sidewall 820 roughly on axis B direction valve guide groove 830.Be connected on the valve sidewall 820 along a pair of valve restricted part 840 of moving of stretching out away from the direction of valve diapire 810 and limit slide block 640.Each valve restricted part 840 is stretched out towards axis B at top end (upside of Figure 13 (a)), thereby the valve hook portion 850 that engages with slider component 640 is provided.
Shown in Figure 13 (b), on the axis B of valve system 530 direction, that forms shorter than valve sidewall 820 to valve restricted part 840.That is arranged to use valve hook portion 850 to limit slider component 640 to valve restricted part 840, and valve sidewall 820 is arranged and is used for using that valve guide groove 830 is prevented slider component 640 along the direction of operating skew simultaneously, and is used for depositing first spring member 630.Therefore, longer and big to valve restricted part 840 on the axis B direction that valve sidewall 820 forms at valve system 530 than that.
Shown in Figure 13 (c), on the axis B of valve system 530 direction (with the vertical direction of Figure 13 (c) paper), in valve diapire 810, with that position corresponding to valve restricted part 840 to valve guide groove 830 and that, be formed with four Chinese stick flow channels 860.These black flow channels 860 extend through valve diapire 810 along vertical direction (with the vertical direction of paper of Figure 13 (c)).In addition, valve receiving unit 870 is located on the valve diapire 810, protrudes upward (front side of the direction vertical with the paper of Figure 13 (c)) from bottom valve diapire 810, and is formed for receiving the pedestal at the spring top 920 of first spring member 630.Valve receiving unit 870 comprises two tabular components that roughly are parallel to each other and arrange on valve diapire 810.In addition, shown in Figure 13 (e), valve receiving unit 870 along the height of axis B direction fully less than the height of valve sidewall 820.Valve receiving unit 870 is arranged and is used for asking the contact that prevents when middle between first spring member 630 and valve diapire 810 first spring member 630 being arranged in sky valve sidewall 820 in.This layout is necessary, because if first spring member, 630 contact valve diapires 810, then black flow channel is closed and ink does not flow.Valve receiving unit 870 is arranged and is used for by guaranteeing that first spring member 630 does not contact valve diapire 810 and guarantees that ink flows.Therefore, only need minimum height.
Figure 14 demonstrates first spring member 630.Figure 14 (a) is the side view of first spring member 630, and Figure 14 (b) is the top view of first spring member 630, and Figure 14 (c) is the bottom view of first spring member 630, and Figure 14 (d) is the cutaway view at first spring member 630 shown in Figure 14 (b).
Shown in Figure 14 (d), in first spring member 630, black flow channel 940 extends to the top (end face on the right side of Figure 14 (d)) at spring top 920 from the bottom surface (end face in the left side of Figure 14 (d)) of spring bottom 910.Flexible portion flow channel 942 that this China ink flow channel 940 comprises top flow channel 941 that the interior perimeter surface by spring top 920 forms, formed by the interior perimeter surface of spring flexible portion 930 and the bottom flow channel 943 that forms by the interior perimeter surface of spring bottom 910.Shown in Figure 14 (d), the orifice area of black flow channel 940 becomes big from the top at spring top 920 gradually to the bottom surface of spring bottom 910.In addition, as Figure 14 (b) with (c), the top flow channel 941 at spring top 920 is as from seeing the same general square shape shape that forms with the vertical direction of paper.
The vent surface of top flow channel 941 forms the general square shape shape, thereby can reduce the influence that is caused by the bubble in ink.For example, if top flow channel 941 forms the circular shape along the direction vertical with paper, then diameter may be closed this flow channel greater than the spherical bubbles of top flow channel 941.If flow channel is closed, then ink can not correctly be transferred to ink-jet printer 1710 (referring to Figure 26) from print cartridge 1.Therefore, the poor print quality of this ink-jet printer 1710.But, in the embodiment shown in for example Figure 14 (b), because the vent surface of top flow channel 941 has the general square shape shape, so even the bubble bigger than the vent surface of top flow channel 941 occur, these bights are not closed yet.Therefore, prevent closing of black flow channel, and reduced the possibility of poor print quality.
The vent surface that it should be understood that top flow channel 941 is not limited to square configuration.Other polygonal shape for example hexagon or star shape also is an acceptable.
Shown in Figure 14 (d), spring top 920 forms cylinder form, and it is thicker relatively and extend along axis B direction.Spring top 920 forms and makes and the vertical shape of cross section homogeneous of axis B direction (press direction of first spring member 630).Equally, spring bottom 910 also forms cylinder form, and it is thicker relatively and extend along axis B direction, and the shape of cross section homogeneous vertical with axis B direction.
In addition, shown in Figure 14 (d), spring flexible portion 930 forms the conical shaped shape, and it becomes predetermined angle incline with respect to axis B direction, bears along the intensity of the spring flexible portion 930 of the load of axis B direction thus less than the intensity at spring bottom 910 and spring top 920.In addition, the thickness of spring flexible portion 930 is less than the thickness at spring bottom 910 and spring top 920, thereby helps to make the intensity of spring flexible portion 930 less.Therefore, when first spring member, 630 strains, 930 flexural deformations of spring flexible portion.
Figure 15 demonstrates slider component 640.Figure 15 (a) is the front view/rearview of slider component 640, Figure 15 (b) is the left side view/right side view of slider component 640, Figure 15 (c) is the top view of slider component 640, Figure 15 (d) is the bottom view of slider component 640, and Figure 15 (e) is the cutaway view at the slider component 640 shown in Figure 15 (c).
As Figure 15 (a) with (b), slider component 640 is formed by hardness ratio first spring member 630 and second spring member, 650 big resin materials, and comprises: slide block periphery wall 1010, and it forms the periphery of slider component 640; Two slide block juts 1020, they from slide block periphery wall 1010 along valve system 530 axis B direction extend, and be symmetrically formed about axis B; And the loose insertion member 1030 of a pair of slide block, they are arranged on slide block periphery wall 1010 and the slide block jut 1020 along slide block periphery wall 1010 and slide block jut 1020, and be symmetrically formed about axis B, and loose insertion that to valve guide groove 830 (referring to Figure 13).Slide block periphery wall 1010 and slide block jut 1020 form the substantial cylindrical shape together.
Roughly the height with slide block periphery wall 1010 is identical along the height of axis B direction for slide block jut 1020.This is because spring member 630,650 is arranged in slider component 640 in the inner space 1060,1070 of axis B direction.In addition, each spring member 630,650 moving along the direction vertical with axis B by slide block jut 1020 and 1010 restrictions of slide block periphery wall.
The loose insertion member 1030 of slide block is extending (being formed on slide block periphery wall 1010 and the slide block jut 1020) along slider component 640 on the axis B direction.Slider component 640 smoothly carries out the cooperation between the valve guide groove 830 (referring to Figure 13) along moving through at the loose insertion member 1030 of slide block and that of axis B direction.
As Figure 15 (c) with (d), in the inboard of slide block periphery wall 1010, be provided with slide block base part 1040, on this slide block base part 1040, arrange each spring member 630,650.The spring bottom 910 of slide block base part 1040 each spring members 630,650 of contact.Slide block base part 1040 marks off two inner spaces 1060,1070 that hold respective springs member 630,650 in slider component 640.In the central authorities of slide block base part 1040, be formed with slide block through hole 1050, and this slide block through hole 1050 becomes the flow channel that ink flows.Shown in Figure 15 (e), on the axis B of slider component 640 direction, slide block base part 1040 is formed on roughly centre position.
Figure 16 demonstrates base component 660.Figure 16 (a) is the side view of base component 660, and Figure 16 (b) is the top view of base component 660, and Figure 16 (c) is the bottom view of base component 660, and Figure 16 (d) is the cutaway view at the base component 660 shown in Figure 16 (b).
Shown in Figure 16 (a), base component 660 is provided with: base bottom 1110, and it forms the bottom surface of base component 660, and contacts the spring top 920 of second spring member 650; Pedestal mid portion 1120, it is formed with the external diameter littler than the external diameter of base bottom 1110; And pedestal receiving unit 1130, these pedestal receiving units 1130 are arranged on the end face (upside of Figure 16 (a)) of pedestal mid portion 1120.Pedestal receiving unit 1130 is provided with downward-sloping basement tilt face 1131 near base component 660 central authorities, and check-valves described later is received by these basement tilt faces 1131.
Shown in Figure 16 (b), six pedestal receiving units 1130 along the circumferencial direction of base component 660 with arranged at predetermined intervals.In addition, three in these six pedestal receiving units 1130 comprise the first pedestal through hole 1140 that extends to the back side from the front of base component 660.These first pedestal through holes 1140 are formed in the part except the part that is provided with basement tilt face 1131 (horizontal component of pedestal receiving unit 1130) of pedestal receiving unit 1130.Therefore, the first pedestal through hole 1140 is formed in the part except the part that receives check-valves 670.This structure prevents the ink constricted flow.
In addition, between the pedestal receiving unit 1130 of base component 660, be formed with the second pedestal through hole 1150 that extends through pedestal mid portion 1120 and base bottom 1110.These second pedestal through holes 1150 are formed between the pedestal receiving unit 1130, thereby six second pedestal through holes 1150 form along circumferencial direction around base component 660.The second pedestal through hole 1150 forms the black flow channel that allows ink flow through.
Shown in Figure 16 (c), on the bottom surface of base bottom 1110, be formed with concave base groove 1160, they are connecting the corresponding second pedestal through hole 1150.These pedestal grooves 1160 are to connect those second pedestal through holes 1150 through axis B and about the form of the roughly straight line of axis B symmetry.Therefore, in base bottom 1110, be formed with three pedestal grooves 1160, they intersect each other at axis B place.
Shown in Figure 16 (d), between the basement tilt face 1131 and the second pedestal through hole 1150 of pedestal receiving unit 1130, be formed with the gap along axis B direction.Therefore, even when check-valves 670 is supported by basement tilt face 1131, guarantee that also ink flows.In addition, for pedestal groove 1160, therefore the end face at the spring top 920 of second spring member 650 is arranged on the inboard of the second pedestal through hole 1150, even when the end face contact base component 660 at the spring top 920 of second spring member 650, pedestal groove 1160 guarantees that also ink flows.
Figure 17 demonstrates check-valves 670.Figure 17 (a) is the side view of check-valves 670, and Figure 17 (b) is the top view/bottom view of check-valves 670, and Figure 17 (c) is the cutaway view at the check-valves 670 shown in Figure 17 (b).
Check-valves 670 is roughly tabular.The check-valves flat 1210 that forms the end face of check-valves 670 constitutes by contact cover component 680 closes black flow channel.In addition, the check-valves sweep 1220 of the curved surface of formation check-valves 670 is received by the pedestal receiving unit 1130 of base component 660.Therefore, when the check-valves sweep 1220 of check-valves 670 was received by the pedestal receiving unit 1130 of base component 660, black flow channel was opened, and when the check-valves flat 1210 contact cover components 680 of check-valves 670, black flow channel is closed.
Figure 18 demonstrates cover component 680.Figure 18 (a) is the side view of cover component 680, and Figure 18 (b) is the top view of cover component 680, and Figure 18 (c) is the bottom view of cover component 680, and Figure 18 (d) is the cutaway view at the cover component 680 shown in Figure 18 (b).
Shown in Figure 18 (b) and 18 (c), in cap top 1320, run through cap top 1320 at a plurality of circumferential positions and be formed with six lid through holes 1330.These lid through holes 1330 become the flow channel that allows ink flow through, and when check-valves 670 contact cap top 1320, these lid through holes 1330 are closed, and close black flow channel.
Next, with reference to Figure 19 the print cartridge 1 that assembles is described.Figure 19 is the cutaway view at the print cartridge shown in Fig. 21.In the cutaway view of print cartridge shown in Figure 19 1, ink I is stored in the framework 100.
Figure 19 demonstrates the state that has wherein assembled print cartridge 1 by welded case 200 and block 300.Under this state, the block diapire 310 of joint member 610 contact blocks 300.Simultaneously, the periphery wall of ink guide part 140 is bonded in the joint trench portions 740 of joint member 610.In addition, the interior perimeter surface of the outer surface of joint member 610 (joint outer peripheral portion 710 (referring to Figure 12)) contact block blank area 360.Therefore, the inner space 1440 that is surrounded by housing 200 and block 300 is not connected with the outside of housing 200 with block 300, and roughly sealing.
A pair of film 1430 is welded on the chassis body part 110.Ink I is stored in roughly by in these film 1430 sealed space (ink storage area 120).The back describes the process of welding these films 1430.
That is double deck type film (being referred to below as " nylon polyethylene ") to film 1430, and each film comprises nylon film and polyethylene film.That side that is contacting chassis body part 110 is a film layer.The complete fluid partitioning of this nylon polyethylene, but more incomplete gas barrier character had.Therefore, between ink storage area 120 that is roughly sealed and inner space 1440, may exist minimum gas to be communicated with by film 1430.The gas that exists among the ink I in the ink storage area 120 permeates gradually and passes film 1430, and moves to inner space 1440.Therefore, can prevent from ink I, to produce bubble, and can prevent the poor print quality that causes owing to the bubble in ink I.Film 1430 can be formed by any material, as long as can keep intensity and this material to have some gas permeabilities.For example, the film that can use the bilayer film that forms by nylon film and polypropylene film and mix and form by nylon and polyethylene or nylon and polypropylene.
In addition, as shown in figure 19, between the ink supply aperture 122 and cover component 680 of framework 100, be formed with black flow channel 1410, it is provided with hollow cone shape part or the bowl-shape part that port size reduces to ink supply aperture 122 from cover component 680.In addition, on ink supply aperture 122 sides of the bowl-shape part of black flow channel 1410, be formed with the hollow cylindrical part, it is connected with the smaller diameter side of bowl-shape part.On cover component 680 sides of the bowl-shape part of black flow channel 1410, be formed with the hollow cylindrical part, it is connected with the larger diameter side of bowl-shape part.In black flow channel 1410, in order to remove dust and/or the impurity in the ink I of ink storage area 120, be provided with the filter 1420 that forms by the foam type material.That is to say that black flow channel 1410 is accommodated chamber for the filter of accommodating filter 1420.Filter 1420 forms the cylinder form with diameter (identical shape of cross section) identical with the maximum gauge (near the diameter of black flow channel 1410 cover component 680) of black flow channel 1410, and by inserting filter 1420 along the direction (with the parallel direction of axis B direction of valve system 530) that makes ink advance black flow channel 1410 from ink guide part 140 effluents and filter 1420 being arranged under compressive state in the black flow channel 1410.Therefore, compare, can obtain to have filter than fine holes with the state before inserting.For example, the percentage (inclined plane of for example black flow channel 1410 of inner surface configuration) that dwindles of the port size by suitably selecting black flow channel 1410 is regulated compression percentages, thus characteristic (impurity removal efficacy) that can controlled filter device 1420.Therefore, can under the situation of the material that does not change filter 1420, obtain desired filter characteristic.In embodiment shown in Figure 19, filter 1420 is formed by polyurethane material, and CFH40 also is acceptable but for example be to use.If dust and/or impurity reside in the China ink pipe (not shown) and/or valve system 530 of ink-jet printer 1710 (referring to Figure 26), then not accurately ink supply, and can make poor print quality.But, by filter 1420 is provided, can remove dust and/or impurity, therefore ink supply can be accurately carried out, and poor print quality can be prevented.
Optionally, if when the sheet screen member being installed or being welded on the ink supply aperture 122 so that filtering, then need installation process, and/or chassis body part 110 must be manufactured and have demountable structure.Therefore, it is complicated more that the structure of chassis body part 110 will become, and the manufacturing 1 required time of print cartridge will increase.On the contrary, filter 1420 is inserted into the installation of just having finished filter 1420 in the black flow channel 1410.Therefore, simplify the structure of chassis body part 110, and also can simplify manufacture process.
In the time of in being inserted into black flow channel 1410, owing to the restriction that is subjected to ink supply aperture 122 along moving of direction of insertion, filter 1420 is compressed along direction of insertion (with the parallel direction of axis B direction of valve system 530).This filter 1420 is also compressed along the in-plane vertical with direction of insertion by the inner surface of the hollow cone shape shape of black flow channel 1410.Therefore, this filter 1420 on three-dimensional equably by compression.Therefore, this filter 1420 is whole equably by compression, thereby stable filter characteristic is provided.
Therefore the diameter of ink supply aperture 122 prevents that filter 1420 from entering black flow channel 1410 and being deeper than required less than the diameter of filter 1420.Prevent that also filter 1420 from sliding in the ink storage area 120.But, slide in the ink storage area 120 in order further to prevent filter 1420 reliably, also can be provided with and be used for preventing that filter 1420 from sliding into the member in the ink supply aperture 122.
In addition, as shown in figure 19, on that side (downside of Figure 19) opposite of black flow channel 1410, be provided with bonding part 1450 with ink storage area 120, it is connected with black flow channel 1410, and engages with the housing that is formed by base component 660 and cover component 680.The internal diameter of bonding part 1450 is greater than the internal diameter of black flow channel 1410, and forms slightly littler than the external diameter of cover component 680.Base component 660 and cover component 680 engage and are fixed on the bonding part 1450.Therefore, the mode of base component 660 and cover component 680 filter 1420 when contacting that pressurized is in compressive state in black flow channel 1410 is fixed on the bonding part 1450.Gu Ding base component 660 and cover component 680 are used for preventing that as retainer filter 1420 is from black flow channel 1410 landings like this.
On that side (downside of Figure 19) opposite of bonding part 1450, be provided with valve system insertion portion 1460 (in this valve system insertion portion 1460, also comprising bonding part 1450) with black flow channel 1410.Valve system insertion portion 1460 is connected with bonding part 1450, and valve system 530 is inserted in this valve system insertion portion 1460.This valve system insertion portion 1460 also is black flow channel.Be formed on space in the black flow channel 1410, be formed on the space in the bonding part 1450 and be formed on the black flow channel chamber that space in the valve system insertion portion 1460 forms ink guide part 140, this chamber becomes ink-feed channel when giving print cartridge 1 outside ink supply.As shown in figure 19, this China ink flow channel chamber is formed on the inside of the ink guide part 140 that forms cylinder form.In addition, as shown in figure 19, when being inserted into valve system 530 in the valve system insertion portion 1460, the pitch angle shaped of the inclination angle of block through hole 330 and the tapering part flow channel 761 of joint member 610 becomes identical.In addition, the connection plane between tapering part flow channel 761 and block through hole 330 is without any ladder.Therefore, pumping ink pipe 1720 (referring to Figure 26) can be inserted in the black flow channel 760 smoothly.
Valve system 530 is arranged such that: the bottom surface contact block diapire 310 of joint member 610, and the joint contact portion 730 of joint member 610 can contact the valve diapire 810 of valve member 620.In the inside of valve member 620, deposited first spring member 630, thus the spring top 920 of the valve receiving unit of valve member 620 870 contacts first spring member 630.In addition, first spring member 630 and second spring member 650 leave in two inner spaces 1060,1070 that the slide block base part 1040 by slider component 640 marks off.The bottom surface 911 (referring to Figure 14) of spring bottom 910 is contacting the surface 1041 (referring to Figure 15) of valve member 620 sides of slide block base part 1040.Simultaneously, the inwall 1042 (referring to Figure 15) of outer circumferential side surface 912 (referring to Figure 14) the contact slipper periphery wall 1010 of spring bottom 910.Equally, for second spring member 650, the surface 1043 (referring to Figure 15) of that side (check-valves 670 sides) opposite of the bottom surface 911 contact slipper base parts 1040 of spring bottom 910 with valve member 620.Simultaneously, the inwall 1021 (referring to Figure 15) of the outer circumferential side surface 912 contact slipper juts 1020 of spring bottom 910.Therefore, slide block base part 1040 is the part that first spring member 630 engages second spring member 650.As shown in figure 19, slide block base part 1040 is clipped by the spring bottom 910 of first spring member 630 and second spring member.In addition, the valve hook portion 850 that is inserted in two valve members 620 between the slide block jut 1020 is contacting the surface 1043 of slide block base part 1040.This surface 1043 is the surface that contacts with the bottom surface 911 of the spring of second spring member 650 bottom 910.Therefore, slider component 640 engages with valve hook portion 850.The spring top 920 of second spring member 650 can contact the base bottom 1110 of base component 660.In addition, check-valves 670 leaves between base component 660 and the cover component 680.The back will be elaborated to the layout and the operation of each member of valve system 530.
Make the process of framework 100 below with reference to Figure 20 and 21 explanations.Figure 20 demonstrates the schematic cross sectional views of the process of making framework 100.This manufacture process advances to Figure 20 (d) from Figure 20 (a).Figure 21 is the enlarged drawing in the portion C of the schematic cross sectional views shown in Figure 20 (c).
At first, be described in employed framework manufacturing equipment 1510 in this manufacture process.This framework manufacturing equipment 1510 is provided with and is used for installing with the base part 1520 of support frame main part 110, applies the vacuum plant 1530 of vacuum, film 1430 is pressed in the pressures partially 1540 on the chassis body part 110 and is used for film 1430 is welded on welder 1550 on the chassis body part 110 to film 1430.
In base part 1520, be formed with spill substrate retaining part 1521, it can installation frame main part 110.This substrate retaining part 1521 forms the general square shape shape corresponding with the profile of chassis body part 110.In addition, though not shownly go out, this substrate retaining part 1521 has and refilling part 130 and ink guide part 140 corresponding concave part, and positions when installation frame main part 110.In addition,, clamper component be can also provide, (upside of Figure 20 (a)) or side (horizontal direction of Figure 20 (a)) fixed frame main part 110 are used for from the top in order to position.
Pressures partially 1540 is provided with pressurization elastic part 1541, and the top ends (downside of Figure 20 (a)) of this pressurization elastic part 1541 is formed by elastomeric material.The top of this pressurization elastic part 1541 forms the corresponding roughly spherical form of shape with the ink storage area 120 of chassis body part 110.In the top ends of pressurization elastic part 1541, so that during the framework inclined plane 124 of contact frame main part 110, pressurization inclined plane 1542 forms corresponding with the inclination alpha (referring to Figure 21) on framework inclined plane 124 at pressures partially 1540 extrusion films 1430.Therefore, when film 1430 is subjected to pressures partially 1540 extruding, prevent between the framework inclined plane 124 of chassis body part 110 and film 1430, to form the gap.In addition, in pressures partially 1540, be provided with the control member 1543 that floats, when pressures partially 1540 extrusion films 1430, float (following) of these unsteady control member 1543 control films 1430.The control member 1543 that floats is installed on the periphery of pressurization elastic part 1541, and near control film 1430 floating framework haunched member 111.
Describe below film 1430 is welded on process on the chassis body part 110.
In this welding process, chassis body part 110 is arranged in the substrate retaining part 1521 of base part 1520, and film 1430 is vacuumized by vacuum plant 1530 (Figure 20 (a)).At this moment, by cutting out the film 1430 bigger, thereby can reliably film 1430 be welded on the chassis body part 110 than the profile of chassis body part 110.
In Figure 20 (a), for example when connecting the starting switch (not shown) of framework manufacturing equipment 1510, vacuum plant 1530 descend (Figure 20 (b)).Shown in Figure 20 (b), when vacuum plant 1530 descends, film 1430 contact frame haunched members 111.
Then, pressures partially 1540 descends towards base part 1520 directions (below of Figure 20 (c)), and the pressurization inclined plane 1542 of pressures partially 1540 is by the framework inclined plane 124 (state of Figure 20 (c)) of film 1430 contact frame main parts 110.When pressures partially 1540 contact membranes 1430, (be included in actual contact), stop to apply vacuum, and film 1430 can move by vacuum plant 1530 before with afterwards.Therefore, film 1430 is by pressures partially 1540 extruding, and towards central authorities' motion of the framework through hole 123 of chassis body part 110.
In addition, shown in Figure 20 (c), the part of film 1430 is extruded passes framework through hole 123, arrive that side that is provided with framework inclined plane 124 (the framework inclined plane 124 of the downside of Figure 20 (c)) up to this part, this side be with in that the opposite side of framework inclined plane 124 (the framework inclined plane 124 of the upside of Figure 20 (c)) that is contacting on that side of pressures partially 1540.By the middle body of extrusion film 1430, thereby in the middle body of film 1430, produce lax by framework through hole 123.This lax by having, but using ink and less quantity of ink time spent (ink storage area 120 is empty state), and a pair of upper and lower film 1430 can be attached together, and can consume ink effectively.Optionally, film 1430 can be owing to (for example, dwindling) is out of shape in the influence of the outside surround that is furnished with these films.But, the lax damage that has prevented film 1430 is provided.
In addition, because film 1430 is subjected to pressures partially 1540 extruding, so the thickness of film 1430 does not change.For example, if when these film 1430 integral body being heated and make it to extend, weld, then can weld these films 1430, but these films 1430 will have scrambling on thickness, thereby reduce the structural strength of these films 1430 with the shape consistent with framework inclined plane 124.But when these films 1430 were pushed by pressures partially 1540, the inclination angle was clipped in film between pressurization inclined plane 1542 and the framework inclined plane 124, and these inclined planes have roughly the same inclination angle.As hereinafter described, a welding region to pressures partially 1540 outsides heats.Therefore, the thickness of film 1430 does not change, and does not produce the thickness scrambling.Therefore, can prevent the Strength Changes of film 1430 and the damage of film 1430.
Here, with reference to Figure 21 the operation of the control member 1543 that floats is described.The control member 1543 that should float is arranged and is used for controlling floating of film 1430.For example, because film 1430 is clipped by pressures partially 1540 and framework inclined plane 124, so there is following situation, promptly under the situation of the control member 1543 that do not float, film 1430 rises along the inclination alpha on framework inclined plane 124.This phenomenon partly is because stopped applying vacuum by vacuum plant 1530.But, if do not stop to apply vacuum, then also there is a problem by vacuum plant 1530, promptly film 1430 can not move smoothly.Therefore, in the embodiment shown in Figure 21, stop to apply vacuum, and be provided with the control member 1543 that floats by vacuum plant 1530.If film 1430 rises between framework inclined plane 124 and framework haunched member 111, then in film 1430, may produce lax, and film 1430 contact frame haunched member 111 not.Therefore, can not accurately weld film 1430.But, in embodiment shown in Figure 21,, can control floating of film 1430 by the control member 1543 that floats is set, therefore can accurately weld film 1430.
With reference to Figure 20, when film 1430 is subjected to pressures partially 1540 extruding, welder 1550 descends along the direction (downside of Figure 20 (d)) of the framework haunched member 111 of chassis body part 110, and the top of welder 1550 is by the top (annular band region) of film 1430 contact frame haunched members 111.Transmit heat from welder 1550, make 111 fusions of framework haunched member, make zone (annular weld zone) fusion that contacts with framework haunched member 111 of film 1430, and carry out thermal weld (Figure 20 (d)).As mentioned above, film 1430 is formed by nylon and polyethylene bilayer, and polyethylene film is arranged to contact frame haunched member 111.In addition, for film 1430 is welded on the framework haunched member 111, chassis body part 110 also can be formed by polyvinyl resin.By using the same resin materials, thereby can reliably film 1430 be welded on the framework haunched member 111 for film 1430 and chassis body part 110.Nylon film is compared with polyethylene film has excellent intensity, but the fusing point of nylon film is higher, and it is relatively poor therefore to weld operability.Therefore, in embodiment shown in Figure 20, film 1430 has nylon and polyethylene double-decker, has therefore guaranteed intensity, and be welded on the layer on the chassis body part 110 and adopt lower welding temperature by the conduct of use polyethylene layer, thereby guarantee to weld operability.In addition, nylon layer not fusion when welding operation, therefore near the change in film thickness welding portion is less, and also can remain near the film strength the welding portion.
After finishing thermal weld, vacuum plant 1530, pressures partially 1540 and welder 1550 are risen and turn back in the position shown in Figure 20 (a).Then, cut the unnecessary part of film 1430 as required.In addition, at this moment, also can carry out cooling procedure, be used for making the part cooling that film 1430 and framework haunched member 111 are welded together.
In addition, in welding process, after pressures partially 1540 declines and pressurization 1542 contact frame inclined planes 124, inclined plane, vacuum plant 1530 stops.Afterwards, welder 1550 descends, and with film 1430 and 111 thermal welds of framework haunched member.But, film 1430 (hour) under the effect on pressurization inclined plane 1542 when being inserted in the framework through hole 123, also can after descending and carry out thermal weld, welder 1550 make vacuum plant 1530 stop to apply vacuum with littler degree at the capacity of ink storage area 120.
Shape relation between film 1430 and chassis body part 110 has been described here.For for the chassis body part 110 of the embodiment shown in Fig. 7, ink storage area 120 forms circular shape (referring to Fig. 7 (a)).But,, then produce the fold of film 1430 in four apex offices of square configuration if ink storage area 120 forms square configuration.If the fold of film 1430 produces and be soldered, then ink may be stayed in the fold part and can not consumed effectively.But in the above-described embodiment, ink storage area 120 forms the circular shape, therefore be difficult in film 1430, form fold, even and in film 1430, be formed with fold, also just produce wrinkling.Therefore, print cartridge 1 can consume ink effectively.Ink storage area 120 also can form elliptical shape.Ink storage area 120 even can form square configuration is as long as apex portion forms smoothed curve.That is to say that the shape of ink storage area 120 is not limit, as long as take to prevent from film 1430, to form the shape of fold.
On the both sides of chassis body part 110, film 1430 is welded on the chassis body part 110 (film 1430 is welded on the downside among Figure 20 (a)).Welding process is identical, therefore omits explanation.
The method of making framework 100 is described below with reference to Figure 22.Figure 22 demonstrates the method for making framework 100.In addition, comprise the film 1430 that welds by welding process in the chassis body part 110 shown in Figure 22.
At first, shown in Figure 22 (a), valve system 530 is installed on the ink guide part 140 (valve system insertion portion 1460 (referring to Figure 19)) of chassis body part 110.In Figure 22 (a), valve system 530 has assembled.In the embodiment shown in Figure 22 (a), joint member 610 is an individual unit, valve member 620, first spring member 630, slider component 640 and second spring member 650 are integral, and base component 660, check-valves 670 and cover component 680 are integral.Hereinafter the process of valve system 530 is assembled in explanation.
At first, filter 1420 is inserted black flow channel 1410 (referring to Figure 19).In addition, the anti-reflux mechanism that one is equipped with cover component 680, check-valves 670 and base component 660 is pressed into (referring to Figure 19) in the bonding part 1450.As mentioned above, the bonding part in ink guide part 140 1450 forms and has the internal diameter slightly littler than the external diameter of cover component 680.Therefore, cover component 680, check-valves 670 and base component 660 are fixed on the bonding part 1450.Afterwards, the unit that one is equipped with valve member 620, first spring member 630, slider component 640 and second spring member 650 is inserted in the valve system insertion portion 1460, and the joint trench portions 740 of joint member 610 is engaged with ink guide part 140, therefore finish the assembling of valve system 530.Before in being inserted into valve system insertion portion 1460, valve member 620, first spring member 630, slider component 640 and second spring member 650 are integral, and base component 660, check-valves 670 and cover component 680 are integral.This process has been simplified the installation process of valve system 530.In addition, as mentioned above, the width of the joint trench portions 740 of joint member 610 forms slightly littler than the thickness of the periphery wall of ink guide part 140, and therefore when valve system 530 had been installed, valve system 530 can not be easy to remove.
Shown in Figure 22 (b), after being installed in valve system 530 on the ink guide part 140, ink-filling needle 1610 injects ink by refilling part 130.
In addition, in Figure 22 (b), when the engaged at end of joint trench portions 740 and ink guide part 140, joint member 610 is fixed on the ink guide part 140.Therefore, the ink supply flow channel of ink guide part 140 is fully closed with the valve member 620 of valve system 530, and therefore the ink that injects can not leak from ink guide part 140.Afterwards, shown in Figure 22 (c), when injecting ink by ink-filling needle 1610, refilling plug 520 is pressed in the refilling part 130.
Shown in Figure 25 (a), refilling plug 520 is formed by elastomeric material.Insert the top and form the convergence circle conical in shape consistent with the inner surface configuration of refilling part 130.Refilling plug 520 is not inserted into the deepest part of refilling part 130 at the beginning, and rear end surface is forced near the position of aperture end face that is positioned at refilling part 130.
Therefore, in the deep end of refilling part 130, be formed with space X, this space X is connected with ink storage area 120 by pouring ink hole 121.Under this state, ink-filling needle 1610 can pass refilling plug 520, thereby the top of ink-filling needle 1610 is arranged in space X, and can import ink.
Keep the corresponding quantity of ink of capacity in case import ink and injected with the maximum of ink storage area 120, as shown in figure 19, then that stretches out to the surface of film 1430 from the frame edge part 112 of chassis body part 110.But, as mentioned above, in the housing sidewall 230 of housing 200, be formed with bandy buckling of shells part 240.Therefore, outward extending film 1430 does not contact the inner surface of housing 200.
In addition, a reason that has refilling part 130 and import ink by refilling part 130 is that the anti-reflux mechanism with check-valves 670 is installed in the ink guide part 140.Anti-reflux mechanism is arranged such that: when being installed in print cartridge 1 on the recording equipment, the ink that offers recording equipment is not back in the print cartridge 1.But because this anti-reflux mechanism, ink can not import by ink guide part 140.Therefore, refilling part 130 arranges that exclusively being used for ink imports, and injects ink by refilling part 130.
The process of making print cartridge 1 is described below with reference to Figure 23.Figure 23 demonstrates the process of making print cartridge 1.
Shown in Figure 23 (a), carry out framework 100 is installed in the operation of block on 300, thereby make ink guide part 140 that can be inserted into that loosely in the block guide groove 361 to the loose insertion member 141 of framework.Simultaneously, install, thereby that is arranged on that between the block limiting member 370 and with that block limiting member 370 being contacted to framework restricted part 150.When engaging block nipple orifice 362 with that framework joint member 142, that has finished the installation of framework 100.As described in reference Fig. 6, when that contacts that to block nipple orifice 362 to framework joint member 142, can prevent from easily framework 100 to be removed.Simultaneously, by that to framework restricted part 150 and that rotation to block limiting member 370 limiting frames 100, therefore can be under without any the situation of swing installation frame 100 and block 300.That is to say that framework 100 and block 300 are installed under the situation of the fixing operation of not undertaken by bonding agent or welding, and that is in contact with one another by mechanical engagement to block nipple orifice 362 to framework joint member 142 and that.Therefore, framework 100 can be easy to move round cylindrical block blank area 360 with respect to block 300.But, framework restricted part 150 and that are prevented the rotation of framework 100 to block limiting member 370 by that.Therefore, assembly operation can be simplified, and the rotation of framework 100 can be prevented.
In the time of on framework 100 being installed in block 300 shown in Figure 23 (b), joint member 610 is between the top ends of ink guide part 140 and 300 the block diapire 310 of blocking a shot.Joint member 610 is clipped between these parts.That is to say that block 300 is as the pressing element of joint member 610 being fixed and being pressed on the ink guide part 140.Can be before carrying out above-mentioned installation process filling ink, but ink leaks from ink guide part 140 after inserting in order to avoid reliably, carries out as Figure 22 (b) after can and being fixed on joint member 610 on the ink guide part 140 forcefully on framework 100 being installed in block 300 and the refilling (c) is operated.
Shown in Figure 23 (b),, housing 200 is installed according to the mode of cover framework 100 installing framework 100 and block at 300 o'clock.Under this state, the ladder (referring to Figure 24 (a)) that the contact of block haunched member 350 is formed by the first aperture end face 211 (referring to Fig. 4) and the second aperture end face 212 (referring to Fig. 4) of housing 200.
Shown in Figure 23 (c), installing block 300 and during housing 200, can use the device for ultrasonic welding (not shown) to weld block haunched member 350 and housing 200 (stepped surfaces between the first aperture end face 211 and the second aperture end face 212) from 300 the diapire side of blocking a shot.The dotted line of Figure 23 (c) is corresponding with the position that is formed with block haunched member 350, and can fetch welding dotted line position by supersonic welding.
Here, with reference to Figure 24 the process of welded case 200 and block 300 is described.Figure 24 demonstrates can welded case 200 and the amplification view of a part of print cartridge 1 of block 300.Figure 24 (a) demonstrates the state before welding, and Figure 24 (b) demonstrates the state after welding.
Figure 24 (a) demonstrates a kind of state, the ladder that 300 block haunched member, 350 contacts of wherein blocking a shot are formed by the first aperture end face 211 and the second aperture end face 212 of housing 200, thus make a part of otch of end face.In Figure 24 (a), between block 300 block sidewall 320 and housing sidewall 230, be formed with minim gap.Under this state, 300 block diapire 310 sides are applied to the ultrasonic wave part on the position corresponding with the haunched member 350 of blocking a shot from blocking a shot.Ultrasonic bonding is a technique known, therefore omits its detailed description.
Shown in Figure 24 (b),, make housing bore notch portion 210 fusion and the welding together of block haunched member 350 and housing 200 fetch welded case 200 and block 300 o'clock by supersonic welding.Then, make the first aperture end face 211 and 212 fusions of the second aperture end face and disappearance, and make the part of the puddle of block haunched member 350, the first aperture end face 211 and the second aperture end face 212 leave in housing sidewall 230 and block in the gap between the sidewall 320 as fusion fragment X (burr).Therefore, by having the gap that is used for storing fusion fragment X between block sidewall 320 and housing sidewall 230, thereby fusion fragment X does not expose to the outside, and print cartridge 1 is attractive in appearance not impaired.
Possibility as the ladder of housing sidewall 230 can form the inclined plane, and the bight of block haunched member 350 can contact this inclined plane.
The operation of refilling plug 520 when illustrating on housing 200 being installed in block 300 with reference to Figure 25 here.Figure 25 demonstrates refilling plug 520 cutaway view during installation.
Shown in Figure 25 (a), the inside of refilling part 130 is refilling channel, and this refilling channel is formed by circumferential portion 131 in injecting.The top (downside of Figure 25 (a)) that the ratio pouring ink hole 121 of the interior circumferential portion 131 of injection deeper extends into print cartridge 1 forms hollow cone shape shape.Because ink storage area 120 is formed by framework inclined plane 124, and the deepest part of circumferential portion 131 becomes the shape consistent with framework inclined plane 124 in injecting, so this structure is provided.In addition, the top of refilling plug 520 forms the convergence circle conical in shape according to the mode that the shape with the interior circumferential portion 131 of injection matches.When producing framework 100 and finishing refilling, the top end face of refilling plug 520 (end face of the upside of Figure 25 (a)) be arranged in roughly the same position, the outer face (end face of the top side of Figure 25 (a)) of refilling part 130 in, and the deepest part of not inserting refilling part 130.As mentioned above, this is in order to obtain space X, and this space X is communicated with pouring ink hole 121, and allows ink to be injected in the deepest part of refilling part 130.(in the deepest part that refilling plug 520 is inserted into refilling part 130 time, do not provide the space X that allows by pouring ink hole 121, so ink can not be imported) by ink-filling needle 1610.Therefore, when importing ink, have following situation, promptly ink I stays the hollow cone shape space X that is arranged in the deepest part of injecting circumferential portion 131.
Shown in Figure 25 (b), in the time of on housing 200 being installed in block 300, if along block 300 directions extruding housing 200 (state of Figure 23 (b)), housing haunched member 260 contact refilling plugs 520, and refilling plug 520 is promoted by housing haunched member 260.At this moment, staying the ink that injects interior circumferential portion 131 is promoted by refilling plug 520.Therefore, ink flows to the ink storage area 120 (referring to Figure 19) from pouring ink hole 121.
Shown in Figure 25 (c), welded case 200 and block 300 o'clock, the deepest part in refilling plug 520 is filled in space X and injects in the circumferential portion 131.Therefore, in injecting in the circumferential portion 131 without any ink, and all ink I can not inject lavishly.As mentioned above, refilling plug 520 is by 260 extruding of housing haunched member.By pushing refilling plugs 520 with housing haunched member 260, framework 100 unlikely swings in housing 200.
In addition, when connecting ink guide parts 140 and refilling part 130 with respect to housing 200, framework 100 floating grounds are supported in the space in the housing 200.But, framework 100 is connected on ink guide part 140 sides by the joint member 610 that is formed by elastomeric material, and be connected on refilling part 130 sides by the refilling plug 520 that forms by identical elastomeric material, so framework 100 is in the space of vibration damping state lower support in housing 200.Therefore, even under impact is applied to situation on the housing 200, vibration is also decayed by elastomeric material and passes to framework 100, therefore can reduce the influence of external impact for framework 100.Therefore, also as shock absorber, the vibration that is used for suppressing to be applied on the housing 200 passes to framework 100 for joint member 610 and refilling plug 520.Compare with the print cartridge that is furnished with special-purpose shock absorber member, reduced number of components.In addition, because housing haunched member 260 is pushing refilling plug 520, slide so prevented refilling plug 520.Though welded case 200 and block 300 o'clock, refilling plug 520 was pressed in the deepest part of refilling part 130 by housing haunched member 260 as mentioned above.But, also can be and then after injecting ink (that is, before the assembling of housing 200 and block 300) refilling plug 520 is pushed to the deepest part of refilling part 130.
As previously described, the ink storage area 120 by ink I being imported framework 100 into, be placed on framework 100 in the housing 200 then and welded case 200 and block a shot and 300 make print cartridge 1.In traditional print cartridge, there is following situation, promptly the outside from housing parts imports ink after being placed on housing on the framework.In this conventional ink cartridge, for the print cartridge of the ink that stores different amounts and/or color, must make framework and housing separately.But, in the above-described embodiment, lay upper shell after in ink being imported the ink storage area 120 of framework 100 into.Therefore, single framework 100 can be shared.That is to say,, also can use single framework 100 even when the multiple hull shape of needs.Therefore, can reduce the manufacturing cost of print cartridge 1.
In addition, the print cartridge 1 that produces by said process comprise be positioned at can not be from the outside visually the refilling part 130 of detected position and refilling plug 520.Therefore, prevented user error dismounting refilling plug 520 and ink spattering.
Next explanation is installed in print cartridge 1 on the ink-jet printer 1710 with reference to Figure 26.Figure 26 is a cutaway view, demonstrates print cartridge 1 is installed in process on the ink-jet printer 1710.Figure 26 (a) demonstrates the state before print cartridge 1 is installed.Figure 26 (b) demonstrates the state after print cartridge 1 is installed.In addition, the print cartridge 1 of Figure 26 schematically demonstrates, so housing 200 and block 300 usefulness solid lines demonstrate, and framework 100 with dashed lines demonstrate.
Shown in Figure 26 (a), in the mounting portion of the print cartridge 1 that ink-jet printer 1710 is installed, be provided with hollow pumping ink pipe 1720, it extends through the joint member 610 (referring to Figure 19) of the valve system 530 in the print cartridge 1 from block through hole 330, and extracts ink I out from print cartridge 1.Pumping ink pipe 1720 is connected with the printhead (not shown) of ink-jet printer 1710 by unshowned flow channel.Pumping ink pipe 1720 stretches out (protruding upward) from the mounting portion of ink-jet printer 1710 among Figure 26.Locate on the top of pumping ink pipe 1720 (upside of Figure 26 (a)), be provided with spill pumping ink groove 1730.Because these pumping ink grooves 1730, so even under the situation of the bottom surface of the valve member 620 (referring to Figure 19) of pumping ink pipe 1720 contact valve systems 530, also obtain black flow channel.
Shown in Figure 26 (a), in the mounting portion of ink-jet printer 1710, be provided with a pair of clamper component 1740, they stretch out (protruding upward) and clip pumping ink pipe 1720 in Figure 26 (a).Top (upper end in Figure 26 (a)) at clamper component 1740 is located, and is provided with anchor clamps bonding part 1750, and stretch out and joint cap sidewall 320 along direction respect to one another these anchor clamps bonding parts 1750.In addition, clamper component 1740 has flexible nature along direction separated from one another (the arrow D direction of Figure 26).When print cartridge 1 was installed, clamper component 1740 was pushed and bending along arrow D direction by block diapire 310.The direction that print cartridge 1 is installed to ink-jet printer 1710 is by the position relation decision between pumping ink pipe 1720 and block through hole 330.
Shown in Figure 26 (b), in the time of on the mounting portion that print cartridge 1 is installed in ink-jet printer 1710, the anchor clamps bonding part 1750 of clamper component 1740 and the engaged at end of the block sidewall 320 of block 300, and print cartridge 1 is fixing.In order to remove print cartridge 1, can make a disengagement in anchor clamps bonding part 1750 and the block sidewall 320 by clamper component 1740 is slided along arrow D direction.
As mentioned above, block sidewall 320 is arranged such that: the fusion fragment X (referring to Figure 24) that produces in the process of welded case 200 and block 300 can not visually see from the outside.In addition, block sidewall 320 is also as the bonding part that print cartridge 1 is fixed on with installing on the ink-jet printer 1710.Therefore, need not the junction surface independent joining jig member 1740 of assigning to, therefore can reduce the structural complexity of print cartridge 1, and can realize that cost reduces.
Below with reference to Figure 27 the operation of valve system 530 when being inserted into pumping ink pipe 1720 in the valve system 530 is described.Figure 27 demonstrates the operation of valve system 530.Figure 27 (a) demonstrates the state before inserting pumping ink pipe 1720.Figure 27 (b) demonstrates the state that inserts pumping ink pipe 1720.Figure 27 (c) demonstrates the state (referring to Figure 26) that fully pumping ink pipe 1720 is inserted in the print cartridge 1.
Figure 27 (a) demonstrates the state before print cartridge 1 is installed in ink-jet printer 1710.At this moment, valve member 620 with the promptly parallel direction of the direction of joint member 610 contact with axis B on be subjected to 630,650 pushings of first and second spring members.Shown in Figure 27 (a), leave first spring member, 630 slight curvatures in the valve member 620 (and slider component 640) in.But, in the spring flexible portion 930 of second spring member 650 on the top that is arranged in slider component 640 (upside of Figure 27 (a)) without any deflection.This structures shape spring member 630 and 650 bending sequence.That is to say that spring flexible portion 930 is first spring member, 630 to the second spring members 650 bendings easily of slight curvature.Therefore, when inserting pumping ink pipe 1720, first spring member 630 is at first crooked, second spring member, 650 bendings then.
When the valve hook portion 850 of valve member 620 engages with the surface 1041 of the slide block base part 1040 of slider component 640, cause the bending of the spring flexible portion 930 of first spring member 630.It is short that distance (referring to Figure 27 (a)) between the end face of valve diapire 810 sides of the end face of valve diapire 810 inboards of valve member 620 and valve hook portion 850 forms total distance of height of the vertical direction height of thickness than the slide block base part 1040 of slider component 640, first spring member 630 and valve jut 750.Therefore, when the valve hook portion 850 of valve member 620 engages with the surface 1043 of slider component 640, in the spring flexible portion 930 of first spring member 630, produce crooked.Valve system 530 occurs scale error along the height of axis B direction during making each parts, so number of components is big more, and then scale error is big more.But, the valve hook portion 850 of slider component 640 contact valve members 620, therefore the scale error in first spring member 630 is unimportant at least.Therefore, reduced the scale error in valve system 530, and the flexible operation of valve system 530 can be stablized.
Shown in Figure 27 (a), the internal diameter of the valve sidewall 820 of valve member 620 forms with the external diameter of the slide block periphery wall 1010 of slider component 640 roughly the same.Therefore, at slider component 640 when the axis B direction of valve system 530 is moved, the skew that can prevent to produce the direction of motion.In addition, the internal diameter of slide block periphery wall 1010 forms with the external diameter of the spring of each spring member 630,650 bottom 910 roughly the same.Therefore, be arranged at each spring member 630,650 under the state on the slide block base part 1040 of slider component 640, reduced the possibility of each spring member 630,650 along the direction vertical (horizontal direction of Figure 27 (a)) skew with axis B.The shape of the valve sidewall 820 of valve member 620 forms with the internal diameter shape of ink guide part 140 roughly the same.Therefore, when axis B direction is moved, can prevent skew at valve member 620, thereby make valve system 530 more stable along the flexible operation of axis B direction.
Shown in Figure 27 (b), pumping ink pipe 1720 is inserted in the joint member 610 and the valve system insertion portion 1460 of ink guide part 140 in the time, the pumping ink pipe 1720 of the valve diapire 810 by contacting valve member 620 makes valve member 620 move along base component 660 directions (the last direction of Figure 27 (b)).With this motion, first spring member 630 by compression.But, when just part is inserted pumping ink pipe 1720, have only first spring member 630 because the motion of valve member 620 and flexural deformation, so not motion of slider component 640, and the slide block base part 1040 of the valve hook portion 850 of valve member 620 and slider component 640 separates.
When further inserting pumping ink pipe 1720, valve member 620 further moves along the direction of base component 660.With this motion, slider component 640 is along direction (with the opposite direction of press direction of first spring member 630 and the second spring member 650) motion of base component 660, and the plastic deformation of second spring member 650 begins.
Shown in Figure 27 (c), in the time of on the mounting portion that print cartridge 1 is installed in ink-jet printer 1710, second spring member, 650 strains, and form by the black flow channel shown in the arrow E.By the black flow channel shown in the arrow E is following flow channel, and it advances successively by ink storage area 120 (referring to Figure 19), ink supply aperture 122 (referring to Figure 19), filter 1420 (referring to Figure 19) in black flow channel 1410, the lid through hole 1330 of cover component 680, the first pedestal through hole 1140 and the second pedestal through hole 1150, pedestal groove 1160, the black flow channel 940 of second spring member 650, slide block through hole 1050, the black flow channel 940 of first spring member 630, be formed on the flow channel between first spring member 630 and the valve receiving unit 870, the black flow channel 860 of valve member 620, the flow channel of the pumping ink groove 1730 of process pumping ink pipe 1720, and pumping ink pipe 1720.This flow channel becomes the primary flow channel that most of ink flows.In addition, the space between the interior perimeter surface of the valve sidewall 820 of valve member 620 and valve system insertion portion 1460 also becomes black flow channel.
In primary flow channel, be formed on the top flow channel 941 in the spring top 920 of first spring member 630 and be formed on the minimum cross-section that top flow channel 941 in the spring top 920 of second spring member 650 becomes this flow channel, and can be easy to the position closed owing to the existence that is included in the bubble in the ink for this flow channel.But as mentioned above, the aperture of top flow channel 941 forms the general square shape shape, therefore can avoid this problem.
With reference to Figure 28 the operation of the joint member 610 when being inserted into pumping ink pipe 1720 in the joint member 610 is described.Figure 28 demonstrates the operation of joint member 610.Figure 28 (a) demonstrates the state before inserting pumping ink pipe 1720, and Figure 28 (b) demonstrates the state after inserting pumping ink pipe 1720.
Shown in Figure 28 (a), under the state before inserting pumping ink pipe 1720, joint jut 750 stretches out along general horizontal direction (direction vertical with axis B), and stepped surfaces 732 approximate horizontal.In addition, the diameter of the top ends 734 of joint contact portion 730 is demonstrated by b.
Shown in Figure 28 (b), when being inserted into pumping ink pipe 1720 the jut flow channel 762 from aperture 722 by tapering part flow channel 761, joint jut 750 moves (mobile jut flow channel 762 in) along the direction of insertion of pumping ink pipe 1720 (Figure 28 (b) upward to).Joint jut 750 is dragged by pumping ink pipe 1720 owing to the friction between interior perimeter surface 751 and pumping ink pipe 1720.At this moment, joint contact portion 730 is owing to interior perimeter surface 733 and stepped surfaces 732 have structure with the base shape otch.Therefore, joint jut 750 is not directly passed to the top ends 734 of joint contact portion 730 along moving of direction of insertion under the effect of pumping ink pipe 1720.Therefore, shown in Figure 28 (b), the top ends 734 of joint contact portion 730 moves along direction of insertion hardly, and the top ends 734 of joint contact portion 730 is mobile a little along the direction of separating with pumping ink pipe 1720 (arrow F direction).The diameter of joint contact portion 730 under this state demonstrated by b1, and is a bit larger tham the diameter b of Figure 28 (a).That is to say that the change of shape that is inserted in the joint member 610 that is accompanied by pumping ink pipe 1720 is the change of shape that joint contact portion 730 moves along arrow F direction.Have the shape that relaxes the surface that tilts from the interior perimeter surface 751 of joint jut 750 towards the top ends 734 of joint contact portion 730 if having without any stepped surfaces 732 and joint contact portion 730 at the boundary of joint contact portion 730 and joint jut 750, thereby then when joint jut 750 distortion under the effect of pumping ink pipe 1720 when the direction of insertion of pumping ink pipe 1720 moves, the distortion of joint jut 750 will be directly passed to joint contact portion 730.Joint contact portion 730 will move along direction of insertion with joint jut 750 then.Therefore, being used for being formed on the insertion stroke of the pumping ink pipe 1720 of the black flow channel between valve member 620 (referring to Figure 27) and the joint contact portion 730 will be very long.In this structure, must make that pumping ink pipe 1720 is longer.If pumping ink pipe 1720 is oversize, then it can contact other member, thereby damages those members easily.But in the embodiment shown in Figure 28, joint contact portion 730 moves along the direction (arrow F direction) with the direction of insertion approximate vertical of pumping ink pipe 1720, and therefore need not long stroke forms black flow channel.Therefore, can reduce the possibility that pumping ink pipe 1720 contacts other members and causes this damage.
Explanation is accompanied by the sense of touch of the installation of print cartridge 1 with reference to Figure 29.Figure 29 is a curve map, demonstrates the sense of touch when print cartridge 1 is installed.The horizontal axis of Figure 29 demonstrates the move distance (stroke) when print cartridge 1 is installed.The vertical axis of Figure 29 is the load that produces when print cartridge 1 is installed.
As shown in figure 29, when print cartridge 1 began installation and pumping ink pipe 1720 contact valve members 620, load increased rapidly.Then, when the spring flexible portion 930 beginning strains of first spring member 630, load reduces rapidly.This state variation is the some c (intermediateness between Figure 27 (a) and Figure 27 (b)) of Figure 29.
Afterwards, if continue print cartridge 1 is installed, then the strain of first spring member 630 is finished, and the strain of second spring member 650 begins.At this moment, load increases rapidly once more.This state is demonstrated by the some d of Figure 29.
Therefore, by having corresponding spring member 630,650, thereby there is the two-stage load variations.Therefore, the people that print cartridge 1 is installed can feel that this of print cartridge 1 is installed in accurately and carries out.This load variations is called as " sense of touch ".Therefore, the user just can confirm without visual inspection whether print cartridge 1 is accurately installed by sense of touch.
In addition, same, change when loading on print cartridge 1 dismounting.As shown in figure 29, this variation is demonstrated by the load curve when the dismounting of print cartridge 1.When print cartridge 1 began to be disassembled, load was higher, because there is the elastic force that makes respective springs member 630,650 turn back to their reset condition, but when the dismounting of print cartridge continued, it is level and smooth that load variations becomes.
With reference to Figure 30 the inclination alpha (referring to Figure 21) on the framework inclined plane 124 of chassis body part 110 is described.Figure 30 is a curve map, demonstrates the relation between inclination alpha, residual ink amount and the memory capacity on framework inclined plane 124.The horizontal axis of Figure 30 (horizontal direction of Figure 30) demonstrates the inclination alpha on framework inclined plane 124, and the vertical axis of Figure 30 (vertical direction of Figure 30) demonstrates residual ink amount (vertical axis in the left side of Figure 30) and memory capacity (vertical axis on the right side of Figure 30).The bullet of Figure 30 demonstrates residual ink amount, and the black point demonstrates memory capacity.
In the embodiment shown in Figure 19, framework inclined plane 124 forms linearity configuration in cutaway view.This structure setting is used for consuming effectively ink and reduces the ink remaining amount that is stored in the ink storage area 120.That is to say that when forming curved shape on framework inclined plane 124 in cutaway view, in the ink amount of accommodating hour, film 1430 is contact frame inclined plane 124 accurately.Therefore, between framework inclined plane 124 and film 1430, leave minim gap, and ink is stored in this gap.
In addition, the framework inclination alpha on framework inclined plane 124 is set in the angle place that can obtain big ink memory space and can reduce residual ink amount.In the above-described embodiment, the framework tilt angle alpha is set at 30 °.For print cartridge 1, determine minimum permission memory capacity.Memory capacity is 23 milliliters (being referred to below as " ml "), and this is shown as straight dashed line f1 in Figure 30.As shown in figure 30, from the viewpoint of minimum memory size, preferably, the inclination alpha on framework inclined plane 124 forms 27 ° or higher.
In addition, for residual ink amount, determine the desired value of maximum permission surplus.Desired value is 1.5ml or still less.This desired value is shown as the straight dashed line f2 in Figure 30.From the viewpoint of residual ink amount, preferably, the inclination alpha on framework inclined plane 124 forms 34 ° or littler.
As shown in figure 30, memory capacity and high inclination-angle α become big pro rata.But residual ink amount increases rapidly during greater than 30 ° in the value of inclination alpha.Analyze according to this, the optimum angle of incidence α on framework inclined plane 124 is 30 °.
In addition, preferred inclination alpha is 27 ° or bigger aspect memory capacity.But, consider residual ink amount, preferably this inclination alpha is in 28 ° to 34 ° scope e.Any inclination alpha that is set in this scope will be suitable.
In the above-described embodiment, framework 100, housing 200 and blocking a shot 300 formed by resin material.Valve system 530 is also formed by resin material.Owing to do not use the structural detail of metal material, can dispose by burning print cartridge 1 as print cartridge 1.For example, in the print cartridge that the pushing member of valve system (for example, corresponding spring member 630,650) is formed by metal, when disposal, print cartridge need be taken apart, and need remove the pushing member.This additional step has improved cost of disposal.Because the structural detail of print cartridge 1 is combustible, so can reduce cost of disposal.
With reference to Figure 31 print cartridge 2 is described.In print cartridge 1, the top ends shape (referring to Figure 19) of refilling plug 520 forms the conical shaped shape.Simultaneously, in print cartridge 2, circumferential portion 1830 forms the general hollow cylindrical trench in the injection of the refilling part 1820 of framework 1810.Simultaneously, be inserted into the refilling plug 1840 that injects interior circumferential portion 1830 and form the substantial cylindrical shape.The part that the same section with print cartridge 1 of print cartridge 2 is corresponding demonstrates with identical symbol, so its explanation is omitted.
Figure 31 is the cutaway view of print cartridge 2.As shown in figure 31, for print cartridge 2, the shape of circumferential portion 1830 forms the cylindrical trench of general hollow in the injection of the refilling part 1820 of framework 1810.Pouring ink hole 121 is connected on the end (downside of Figure 31) of the deepest part relative with bore portions (upside of Figure 31) of injecting interior circumferential portion 1830.Be inserted into the refilling plug 1840 that injects interior circumferential portion 1830 and form the substantial cylindrical shape.Therefore, on housing 200 being installed in block 300 and refilling plug 1840 when being promoted by housing haunched member 260, the outer surface of refilling plug 1840 is without any the inner surface of circumferential portion 1830 in contact is injected with gap.That is to say that the connection in injecting between circumferential portion 1830 and the pouring ink hole 121 is stopped up by refilling plug 1840.
Therefore, according to mode identical in print cartridge 1, housing 200 is installed in the block 300 on the time, refilling plug 1840 is subjected to the promotion of housing haunched member 260.Therefore, can simplify the process of making print cartridge 2.In addition, push refilling plugs 1840 by using housing haunched member 260, thereby can reduce the swing of framework 1810.In addition, according to mode identical in print cartridge 1, even housing 200 is being applied under the situation of impact, this impact is also owing to be delivered to framework 1810 and alleviated.Therefore, can protect framework 1810 to avoid external impact.In addition, because housing haunched member 260 extruding refilling plugs 1840, housing haunched member 260 is used for also preventing that refilling plug 1840 from sliding.
As shown in figure 31, for refilling plug 1840, the part that is contacting housing haunched member 260 comprises plug trenches part 1850.Plug trenches part 1850 is a concave channels, and the diameter of this groove forms with the diameter of housing haunched member 260 roughly the same.When refilling plug 1840 was subjected to 260 extruding of housing haunched member, the top of housing haunched member 260 engaged with plug trenches part 1850.Therefore, the position that has reduced refilling plug 1840 contact housing haunched members 260 will be offset and framework 1810 with the possibility of inclination.When framework 1810 tilts, be applied to the load variations on the joint member 610, and ink may leak.Plug trenches part 1850 has prevented this ink leakage.
With reference to Figure 32 print cartridge 3 is described.In print cartridge 1, valve member 620 is pushed along joint member 610 directions by the elastic force of first spring member 630 and second spring member 650, therefore black flow channel is closed (referring to Figure 27 (a)).And in print cartridge 3, valve member 1930 is urged along joint member 610 directions under the resilient force of the helical spring member 1940 that is formed by metal material or resin material, and black flow channel is closed.The part that the same section with print cartridge 1 of print cartridge 3 is corresponding demonstrates with identical symbol, so its explanation is omitted.
Figure 32 demonstrates the cutaway view of the ink guide part 1910 of print cartridge 3.Figure 32 (a) demonstrates and is inserting pumping ink pipe 1720 (referring to Figure 26) state before, and Figure 32 (b) demonstrates the state after inserting pumping ink pipe 1720.
Shown in figure 32, for valve system 1920, in the base bottom 1110 of the base component 660 that engages with bonding part 1450 with close by the joint contact portion 730 that contacts joint member 610 between the valve member 1930 of black flow channel, be furnished with helical spring member 1940, it is formed by the helical spring of conical shaped.
For helical spring member 1940, valve member 1930 can be urged along the direction (downward direction in Figure 32) of joint member 610, therefore helical spring member 1940 also can be arranged such that: the base bottom 1110 of minor diameter contact base component 660, and major diameter contact valve member 1930.
Shown in Figure 32 (b), when being inserted into pumping ink pipe 1720 in the valve system insertion portion 1960, valve member 1930 is promoted along base component 660 directions (Figure 32 (b) upward to) by pumping ink pipe 1720, and helical spring member 1940 by compression.Figure 32 (b) demonstrates and print cartridge 3 is installed in ink-jet printer 1710 (referring to Figure 26) is gone up and n is enclosed internal diameter forms state greater than the external diameter of (n+1) individual circle.Therefore, second to the 4th circle is contained in the first lap.That is to say that the circular cone inclination angle when non-compression is set in such inclination angle, and this inclination angle makes first to fourth circle not interfere on compression direction when compression.Therefore, pumping ink pipe 1720 is being inserted in the valve system insertion portion 1960 and when base component 660 directions promoted valve member 1930, helical spring member 1940 was compressed compact to making the thickness along this direction become the degree roughly the same with loop diameter.Therefore, the valve system that forms cylinder form with valve system that is formed by a plurality of members or helical spring is compared, and can shorten the length of ink guide part 1910, and can make print cartridge 3 littler.In addition, owing to only need to use a helical spring member 1940 as the pushing member, so can simplify the structure of valve system 1920.
Black flow channel under the state that print cartridge 3 is installed on the ink-jet printer 1710 is demonstrated by arrow G.This China ink flow channel is formed by the lid through hole 1330 of cover component 680, the second pedestal through hole 1150 of base component 660, the valve through hole 1950 and the pumping ink pipe 1720 of valve member 1930 successively.

Mounting portion 3530 is provided with the side wall support plate 3540 that supports the side (part of the block sidewall 320 of the part of the side of housing 3510 and block 300) of print cartridge 16 from following direction, receive the diapire gripper shoe 3541 of the block diapire 310 of block 300, push the pushing member 3542 of diapire gripper shoe 3541 along the direction of opposite with installation direction (opposite) with arrow R direction, engage the clamper component 3543 that print cartridge 16 and mounting portion 3530 are locked together by block sidewall 320 with block 300, and the anchor clamps that clamper component 3543 is unclamped from engagement state unclamp member 3544.
In addition, the inboard of side wall support plate 3540 (contacting the face side of the side of print cartridge 16) forms and shape (bending) corresponding shape of the sidewall 320 of blocking a shot.When print cartridge 16 was installed, print cartridge 16 was guided along diapire gripper shoe 3541 directions (right of Figure 46 (a)) by the inboard of side wall support plate 3540.Unclamp in the member 3544 at anchor clamps, be formed with the chute (not shown), it has the shape corresponding shape with housing jut 3520.According to the mode identical with side wall support plate 3540, print cartridge 16 is unclamped member 3544 by anchor clamps chute guides along diapire gripper shoe 3541 directions (right of Figure 46 (a)).Therefore, print cartridge 16 can be installed smoothly, and can prevent from print cartridge 16 to be installed along the direction that tilts with respect to diapire gripper shoe 3541.
In diapire gripper shoe 3541, be formed with through hole 3545, pumping ink pipe 3550 can be inserted by it., insert the pumping ink pipe 3550 that passes through hole 3545 and reach print cartridge 16 sides when installation direction (arrow R direction) moves in diapire gripper shoe 3541.
In clamper component 3543, be formed with inclined plane 3546, it tilts with respect to installation direction (arrow R direction).Unclamp in the member 3544 at anchor clamps, be formed with inclined plane 3547, it is corresponding with the inclined plane 3546 of clamper component 3543.Clamper component 3543 and anchor clamps unclamp member 3544 and are arranged such that these inclined planes (inclined plane 3546 and inclined plane 3547) roughly are parallel to each other.
Figure 46 (b) demonstrates print cartridge 16 and is installed in state on the mounting portion 3530.When being installed in print cartridge 16 on the mounting portion 3530, housing 3510 contacts sidewall gripper shoe 3540 with block sidewall 320, and housing jut 3520 contact anchor clamps unclamp the not shown chute of member 3544, and print cartridge 16 is directed to side wall support plate 3540.When continuing the fitting operation of print cartridge 16, the block diapire 310 contact diapire gripper shoes 3541 of block 300, and diapire gripper shoe 3541 along with opposite direction (installation direction R) pressurized of pushing force of pushing member 3542.At this moment, the inclined plane 3546 of block diapire 310 contact clamper components 3543, and clamper component 3543 is along direction (the last direction of Figure 46 (the b)) bending that separates with block sidewall 320.In addition, when inserting print cartridge 16, the contact between the inclined plane 3546 of block sidewall 320 and clamper component 3543 is interrupted, and clamper component 3543 turns back to its reset condition.Print cartridge 16 pins by joint cap sidewall 320.
Shown in Figure 46 (c), unclamp member 3544 and dismantle print cartridge 16 by push anchor clamps along installation direction (arrow R direction).Then, by contacting with inclined plane 3547 that anchor clamps unclamp member 3544, the inclined plane 3546 of clamper component 3543 is along the direction bending that separates with block sidewall 320, and the joint of clamper component 3543 and block sidewall 320 unclamps.At this moment, pushing force and installation direction that diapire gripper shoe 3541 is urged member 3542 push on the contrary, and move to the position that makes block diapire 310 not contact the inclined plane 3546 of clamper component 3543.
Therefore, during installation, print cartridge 16 is inserted in the mounting portion 3530.During the dismounting of print cartridge 16, push anchor clamps and unclamp member 3544.Therefore, can mount and dismount print cartridge 16 simply.
With reference to Figure 47 print cartridge 17 is described.Figure 47 comprises the schematic cross sectional views of the structure of the emptying state that is used to detect print cartridge 17.
Shown in Figure 47 (a), for the framework 3610 of print cartridge 17, make the inclination angle difference on framework inclined plane 3620,3621.In addition, framework inclined plane 3620 sides and framework inclined plane 3621 sides are connected with framework through hole 3624.On the framework inclined plane 3620,3621 inclination angle not simultaneously, the frame aperture notch portion 3622 of framework inclined plane 3620 sides and the distance between the framework through hole 3624 with different with the distance between the framework through hole 3624 in the frame aperture notch portion 3623 on the framework inclined plane 3621.Therefore, the size of the film 3630 of framework inclined plane 3620 sides is different with the size of the film 3631 of framework inclined plane 3621 sides.Therefore, different in the ink memory capacity on 3620 sides of framework inclined plane with ink memory capacity on 3621 sides of framework inclined plane.
Shown in Figure 47 (a), on film 3630, shield 3640 is installed.In addition, be furnished with connector 3650 on the part of housing 200, it allows to contact with external electric when being installed in print cartridge 17 on the ink-jet printer (not shown).Detecting sensor 3660 is connected with connector 3650 by holding wire.This detecting sensor 3660 is as lower sensor, and it detects the emptying state of print cartridge 17, and for having the transmission-type optical pickocff of luminous component and light receiving part.Therefore, when shield 3640 covered in the luminous component of detecting sensor 3660 and the light path between the light receiving part, detecting sensor 3660 was connected, and detects the ink emptying state.
Figure 47 (a) demonstrates the state that has q.s ink I in framework 3610.Shown in Figure 47 (a), shield 3640 and framework 3610 almost parallels, and do not cover the light path of detecting sensor 3660.
In ink-jet printer, when printing repeatedly, the amount of ink I reduces, and film 3630,3,631 3620,3621 direction bendings along the respective frame inclined plane.At this moment, the ink memory capacity on 3621 sides of framework inclined plane is less, and therefore the ink I on 3621 sides of framework inclined plane at first exhausts, and film 3631 contact frame inclined planes 3621.
In addition, in ink-jet printer, when printing repeatedly, the ink on 3620 sides of framework inclined plane also exhausts, and film 3630 contact frame inclined planes 3620.At this moment, shield 3640 is also by film 3630 contact frame inclined planes 3620.In Figure 47 (b), demonstrate this state.When shield 3640 also contact frame inclined plane 3620, shield 3640 covers the light path of detecting sensor 3660, so detecting sensor 3660 detects the ink emptying state.
Therefore, the same as described, the difference of the aspect, inclination angle by being set in framework inclined plane 3620,3621, thus when exhausting, ink I can determine the bending sequence of film 3630,3631.Have the film 3630 that the capacity of ink I is stored in bigger being used to by shield 3640 is installed in, thereby can accurately detect emptying state.
With reference to Figure 48 print cartridge 18 is described.In print cartridge 17, have different inclination angles by making framework inclined plane 3620,3621, thereby accurately detect emptying state.On the contrary, in print cartridge 18, have different port sizes by making frame aperture notch portion 3770,3771, thereby accurately detect emptying state.The part that the same section with print cartridge 17 of print cartridge 18 is corresponding demonstrates with identical symbol, so its explanation is omitted.
Figure 48 comprises schematic diagram, and these schematic diagrames demonstrate the structure of the emptying state that is used to detect print cartridge 18.
Shown in Figure 48 (a), for the framework 3710 of print cartridge 18, with respect to the horizontal plane the inclination angle of (vent surface of frame aperture notch portion 3770) is identical to make framework inclined plane 3720,3721, but the size difference of the frame aperture notch portion 3770,3771 that constitutes by respective frame inclined plane 3720,3721.That is to say that the orifice diameter of frame aperture notch portion 3770 is different with the orifice diameter of frame aperture notch portion 3771.Therefore, different in the size of the film 3730 on the side of framework inclined plane 3720 (frame aperture notch portion 3770) with the size of film 3731 on the side of framework inclined plane 3721 (frame aperture notch portion 3771).Therefore, different in the ink memory capacity on the side of framework inclined plane 3720 (frame aperture notch portion 3770) with ink memory capacity on the side of framework inclined plane 3721 (frame aperture notch portion 3771).
Because this structure, in ink-jet printer, when printing repeatedly, the amount of the ink I in framework 3710 reduces, and the ink I that is stored on 3721 sides of framework inclined plane at first exhausts.Then, the ink I on 3720 sides of framework inclined plane exhausts (state of Figure 48 (b)).Shield 3640 is installed on the film 3730 that is positioned on framework inclined plane 3720 sides with big ink capacity, and therefore under the state that ink I exhausts, the light path of detecting sensor 3660 is covered, and detects emptying state.
Therefore, the same as described, by adopting, thereby the bending sequence of film 3730,3731 can be determined, and emptying state can be accurately detected at the size difference aspect the aperture of frame aperture notch portion 3770,3771.
With reference to Figure 49 print cartridge 19 is described.In print cartridge 17, have different inclination angles by making framework inclined plane 3620,3621, thereby can accurately detect emptying state.On the contrary, in print cartridge 19, have different thickness by making film 3830,3831, thereby can accurately detect emptying state.The part that the same section with print cartridge 17 of print cartridge 19 is corresponding demonstrates with identical symbol, so its explanation is omitted.
Figure 49 comprises schematic diagram, and these schematic diagrames demonstrate the structure of the emptying state that is used to detect print cartridge 19.
For the framework 3810 of print cartridge 19, the pitch angle shaped on framework inclined plane 3820,3821 is become identical, and the orifice diameter size of frame aperture notch portion 3870,3871 also forms identical.In addition, roughly the same in the ink memory capacity on the side of framework inclined plane 3820 (frame aperture notch portion 3870) with the ink memory capacity on the side of framework inclined plane 3821 (frame aperture notch portion 3871).But the film 3830,3831 of print cartridge 19 has different thickness, and film 3830 forms thicker than film 3831.Therefore, film 3830 is more firm than film 3831, and therefore when the amount of ink I reduced, film 3831 is contact frame inclined plane 3821 at first.Then, film 3830 contact frame inclined planes 3820.Shield 3640 is installed on the thicker film 3830, and therefore under the state that ink I exhausts, the light path of detecting sensor 3660 is covered, and detects emptying state.
Therefore, the same as described, by adopting different intensity, thereby determine the order of film 3830,3831 bending when using ink for film 3830,3831, therefore can accurately detect emptying state.
In addition, in print cartridge 17,18 and 19, shield 3640 is installed on the respective films 3630,3730 and 3830 of plastic deformation.On respective films contact frame inclined plane 3620,3720,3820 o'clock, the direction of motion of shield 3640 may be offset and leave the light path of detecting sensor 3660.Therefore, also can be provided with and be used for shield 3640 is guided to the guiding elements (not shown) of the light path of detecting sensor 3660.For example, guiding elements can be arranged on the both sides according to the mode that clips shield 3640, and can form the path of leading to detecting sensor 3660, perhaps can be by having the direction of motion that is used for assigning to limit shield 3640 with respect to the support portion of the part of frame supported shield 3640.
In print cartridge 17,18 and 19, also can be by using said structure to detect emptying state from the method that the quantity of ink that ejects calculates emptying state with the unshowned control device of use.Adopt this structure to allow even detect more accurately emptying state.
Also detecting sensor can be set on ink-jet printer.In this structure, when print cartridge was installed, the part of housing covered the light path of detecting sensor.The part of housing forms transparent or semitransparent, so that the light that transmission is sent from the luminous component of detecting sensor.This shield 3640 is mounted to feasible: without any ink I the time, shield 3640 enters the part of housing, and covers the light path of detecting sensor.Therefore, even when detecting sensor is located on the ink-jet printer, also can accurately detect emptying state.In addition, if detecting sensor is not arranged in this housing, then can reduce the cost of making print cartridge.
By changing film dimensions, can change the ink capacity on the side of inclined plane.Therefore, in the process of welding film (referring to Figure 20), also can change film amount by the pressures partially extruding.Adopt this structure, film dimensions difference, and ink capacity difference.Therefore, can accurately detect emptying state.
As long as determined the bending sequence of film, then also can weld the film that forms and have the same thin film thickness by different materials.Adopt this structure, even under the identical situation of film thickness, material quality is also different, so film strength is also different.Therefore, the bending sequence of film can be determined, and emptying state can be accurately detected.
Come print cartridge 20 is described with reference to Figure 50.On the block haunched member 350 of print cartridge 1, the end face of housing 200 sides forms the plane.On the contrary, on the block haunched member 3910 of print cartridge 20, the top forms has convergent shape.The part that the same section with print cartridge 1 of print cartridge 20 is corresponding demonstrates with identical symbol, so its explanation is omitted.
Figure 50 comprise print cartridge 20 with the housing 200 of print cartridge 20 and the amplification view of block 300 parts that weld together.
Shown in Figure 50 (a), for print cartridge 20, the top of the block haunched member 3910 of block 300 forms has convergent shape.Therefore, form the situation with plane with the top of block haunched member 3910 and compare, block haunched member 3910 is melted immediately, and fusion fragment X can be easy to flow downward.Therefore, block 300 and housing 200 can weld together in early days.
If the inclined plane of block haunched member 3910 forms along block sidewall 320 and is directed downwards inclination, when 3910 fusions of block haunched member, fusion fragment X is directed to the gap between block sidewall 320 and housing sidewall 230.Therefore, can reduce the possibility that fusion fragment X enters print cartridge.
