When handle is used to cover charge of oil China ink hole 514,514 ' and 514 " and 515; 515 ' and 515 " and gas vents 541,541 ' and 541 " closure plate 542 when being fixedly installed on the upper side edge of lid shown in Figure 6 516; in foamed material chamber 511; 511 ' and 511 " after being loaded, groove 540,540 ' and 540 " form elongated pipe with closure plate 542.The tongue-like pieces 545 of closure plate 542 is stretched out from covering 516, and tongue-like pieces 545 has a pre-portion 543, it be positioned at gas vent 541,541 ' and 541 " the mid point of route.When tongue-like pieces 545 from covering 516 when deviating from, tongue-like pieces 545 is easy to separate with closure plate 542.This can expose gas vent 541 in turn, but the other parts of the lower side of closure plate 542 are not exposed.
In a preferred embodiment, the permanent closure groove 540,540 of closure member 542 ' and 540 " that major part 544 on print the pattern of for example forming by letter and figure.That is printed on pattern, color or other printing printed on the tongue-like pieces 545 and major part 544 in closure plate 542 is different, and tongue-like pieces 545 is passed through neck 543 and linked to each other with major part 544.
For example, In yet another embodiment, the background color of the major part 544 of closure plate 542 is blue, the letter of printing black and other figure on it.The background color of tongue-like pieces 545 for example is yellow or red, with the background color formation contrast of major part 544.Being printed on the letter on the base and the color of figure mainly is black or blue look.Like this, because major part 544 is different with tongue-like pieces 545 design and color each other, so can distinguish to them.Therefore, when needs are taken away tongue-like pieces 545, can cause user's attention.
Each ink supply port 513,513 and 513 " is all sealed up by a film shown in Figure 2 546, and adorns black spicule and insert airtightly respectively and adorn black hole 514,514 ' and 514 " and 515,515 ' and 515 ".Make the black hole 514,514 of first assembling ' and 514 " is communicated with vacuum plant, and with second assemble black hole 515,515 ' with 515 " close.
Vacuum plant make each foamed material chamber 511,511 ' and 511 " and each ink chamber 512,512 ' and 512 " in pressure reduce.When pressure is reduced to predetermined value, stop vacuumizing and with first group of device bore closure.After this, the measuring tube that makes the second assembling Mo Kongyu that printing ink is housed is communicated with.The printing ink that is equipped with in the measuring tube is inhaled into the print cartridge that is in vacuum state, then by corresponding porous member 520,520 ' and 520 " absorb, afterwards, respectively through intercommunicating pore 519,519 ' and 519 " flow into ink chamber 512,512 ' and 512 ".
After the printing ink of ormal weight flows into corresponding ink chamber, closure plate 542 is fixedly mounted on covers on 516 the surface, so that in decompression state lower sealing device hole 514,514 ' and 514 ' and 515,515 ' and 515 ", groove 540; 540 ' and 540 " and intercommunicating pore 541,541 ' and 541 ".After this, closure plate 542 makes foamed material chamber 511,511 ' and 511 ' and ink chamber 512,512 ' and 512 " keep from decompression state.
Before using print cartridge, the tongue-like pieces 545 of closure plate 542 is deviate from, so that neck 543 places of tongue-like pieces 545 are disconnected, separate with major part 544.Therefore, adorn black hole 514,514 ' with 514 " through groove 540,540 ' with 540 " with gas vent 541,541 ' and 541 " fluid is communicated with.Equally, the foamed material chamber is through groove 540,540 ' with 540 " with gas vent 541,541 ' and 541 " thereby be communicated with the atmosphere fluid.Therefore, when preventing the printing ink evaporation, make print cartridge obtain exhaust.
Referring now to Fig. 7 (a) and 7 (b),, wherein, the position of the ink supply port 513 of print cartridge will with record head ink supply spicule 550 centerings.After this, when inserting print cartridge, push it to record head.The tapered segment 551 of ink supply spicule 550 penetrates diaphragm seal 546 and cooperates with the hole of the seal 530 shown in Fig. 7 (a).Because the opening of seal 530 upwards, so when the conical portion 551 of ink supply spicule 550 made seal 530 strains, ink supply spicule 550 just passed seal 530.
When using print cartridge, ink supply spicule 550 passes seal 530.The elasticity of the coupling part 534 of seal 530 impels tapered segment 532 to cooperate with ink supply spicule 550.Even the ink supply spicule 550 of record head has axis not overlap with the center of seal 530 slightly, the ink supply port 513 of ink supply spicule 550 also can be realized air seal.
After print cartridge is installed,, give record head and the ink supply spicule 550 that runs through applies negative pressure, flow into record heads so that the printing ink in the box passes ink supply spicule 550 in order printing ink to be introduced record head or to be utilized the jet performance of printing ink.Because the existence of pressure reduction, this high negative pressure that imposes on print cartridge makes airtightly the tapered segment 532 of print cartridge and big gas phase sealing and the seal 530 that is isolated is risen towards the inside of print cartridge shown in Fig. 7 (a).Therefore, this is pressed to close and helps to make the tapered segment 532 of seal 530 flexibly to press to ink supply spicule 550, thereby helps to seal airtightly print cartridge.
Even ink supply spicule 550 does not insert seal 530 fully, as long as the conical portion of ink supply spicule 550 551 keeps in touch with the tapered segment 532 shown in Fig. 7 (b), the elastic force in the tapered segment 532 of seal 530 keeps in touch tapered segment 532 and ink supply spicule 550.Therefore, even spicule is not inserted fully, also can guarantee the air-tightness of seal 530 and ink supply spicule 550.
Because the top of ink supply spicule 550 is sealed when contact with seal 530, shown in can make the wasted space in the print cartridge very little, can prevent that the air bubble of the piston effect generation when print cartridge is inserted record head from entering print cartridge.
When the nozzle opening by record head applied negative pressure, printing ink via through holes 524 that porous member 520 is absorbed and the through hole of ink supply spicule 550 552 flowed into record head.Be consumed when the printing ink of scheduled volume leaves porous member 520, when the quantity of ink in the porous member 520 reduced, the pressure in the ink chamber 512 surpassed near the holding force of the porous member 520 the intercommunicating pore 519, and therefore, air bubble enters ink chamber 512 through intercommunicating pore 519.Therefore, the pressure in the ink chamber 512 increases, thereby printing ink flows into foamed material chamber 511.
The printing ink that flows into foamed material chamber 511 is absorbed by porous member 520, and the quantity of ink of foamed material chamber 511 is increased.Near the printing ink holding force of the porous member 520 intercommunicating pore 519 and the pressure balanced moment in the ink chamber 512, printing ink stops to the mobile of foamed material chamber 511 from ink chamber 512.
Curve shown in Figure 8 is represented this process.In the figure, alphabetical F represents the force value in the porous member 520 of foamed material chamber 511, and alphabetical G represents the quantity of ink in the ink chamber 512.The printing ink W1 of the initial scheduled volume that contains is consumed in porous member 520, when thereby the quantity of ink in the porous member 520 reduces to predetermined value, because under this predetermined value, pressure in the ink chamber 512 surpasses near the printing ink holding force of the porous member 520 the intercommunicating pore 519, so printing ink just little by little flows into foamed material chamber 511 from ink chamber 512.Till the printing ink holding force that this process proceeds near the porous member 520 of pressure and intercommunicating pore 519 in the ink chamber 512 restores balance again.As a result, although the quantity of ink in the ink chamber 512 is reducing gradually, the quantity of ink in the porous member 520 remains unchanged basically, thereby supplies with record head printing ink by constant pressure reduction with constant speed.
Consume the printing ink W2 of scheduled volume at record head after, in ink chamber 512, can not leave printing ink, but the quantity of ink that is contained in the porous member 520 can equal to supply with discontinuously from ink chamber the quantity of ink of foamed material chamber 511.Thereby, although be not used in the ink chamber 512 making additional printing ink, utilize the quantity of ink that absorbed in the porous member 520 can proceed to print to porous member 520.Consume the printing ink W3 of scheduled volume in print procedure after, the printing ink in the porous member 520 will be used up, and this print cartridge will no longer be kept printing.
Absorbed by porous member 520 in the overall print process that printing ink uses up at whole inks of being adorned from ink chamber 512, the quantity of ink of supplying with printhead is constant.The printing ink of using up in the ink chamber 512 shows that the printing ink in the ink cartridge will soon be used up.If under this degree, insert a new print cartridge, just can guarantee that the printing ink of supplying with record head is not interrupted.
As mentioned above, in print procedure, the inner space of print cartridge of the present invention is remained under the negative pressure state.Except between ink supply port and ink supply spicule, realizing above-mentioned air seal, carry printing ink normally to carry out from ink chamber 512 to foamed material chamber 511, so that it is constant to guarantee to supply with the flow of printing ink of record head.Use description to control the structure of carrying printing ink to foamed material chamber 511 below from ink chamber 512.
