Technical field
The invention belongs to the printer servicing unit, particularly a kind of ink cartridges with pressure regulating mechanism.
Background technology
Ink-jet printer is a kind of common computer peripheral device, and its major function is to carry out the print command that computer is assigned, and ink is printd in paper blank with ink-jetting style by the printhead of ink cartridges.
Yet for a good ink-jet ink casket of design, it must conform with following 2 requirements in design:
1, this ink cartridges must be guaranteed ink cartridges pressure inside Pi not in atmosphere outside pressure P o when not carrying out printing function, is spilt by the printhead of ink cartridges to avoid its inner ink.
2, this ink cartridges is when carrying out printing function, must in the process of printing, provide suitable pressure to ink cartridges inside, make the ink cartridges pressure inside be overcome extraneous atmospheric pressure, and then the ink of ink cartridges inside is printed to carry out by the printhead ejection.
In order to satisfy above-mentioned requirements 1, the main embodiment of industry ties up to ink cartridges inside and applies a negative pressure Pb (back pressure) at present, make ink cartridges when not carrying out printing function, its pressure inside Pi can maintain the state less than external atmospheric pressure Po, is spilt by printhead with the ink of avoiding ink cartridges inside.Again in order to satisfy above-mentioned requirements 2, the main embodiment system of industry uses hotness bubble type (therma bubble type) or piezoelectric type (piezoelectric pressure wave type) printhead to print at present, above-mentioned printhead can produce suitable force of impression P to ink cartridges inside when carrying out printing, as force of impression P during greater than negative pressure Pb, ink cartridges pressure inside Pi will be greater than atmosphere outside pressure P o, make the ink of ink cartridges inside carry out printing function by the printhead ejection, because the ink-jet technology of printhead does not belong to inventive point of the present invention, therefore, will not discuss at this for its technology contents.
Yet; extraneous atmospheric pressure Po changes along with the difference of environment through regular meeting; for example; ink-jet printer carried board a plane when carrying out air transport or using ink-jet printer in the high altitude localities; it is little a lot of that extraneous atmospheric pressure tends to normal atmospheric pressure; its result may cause the atmospheric pressure Po of ink cartridges pressure inside Pi greater than the external world, thereby cause ink cartridges when not carrying out printing function, and its inner ink but can be oozed out by printhead automatically.In addition, when the ink of ink cartridges inside exhausts gradually, the negative pressure Pb of ink cartridges inside will be increasing, when the negative pressure Pb of ink cartridges inside value during greater than force of impression P that printhead provided, this ink-jet printer can't be carried out printing function and the ink cartridges that must more renew again, even ink cartridges inside is still residual many inks that still use up be arranged.
Be directed to the existing shortcoming of above-mentioned ink cartridges, the U.S. the 5th, 409, No. 134 patent has proposed a kind of ink cartridges pressure sensitive structure (Pressure-sensitive accumulator for ink-jetpens), negative pressure Pb to ink cartridges inside adjusts by this pressure sensitive structure, the ink cartridges pressure inside is kept in the proper range less than external atmospheric pressure, exosmosed or ink that ink cartridges inside takes place does not exhaust the situation that promptly can't use as yet with the ink of avoiding causing ink cartridges inside.
As shown in Figure 1 and Figure 2, known ink cartridges 1 pressure sensitive structure 10 comprises flexible member 12 and flexible air-bag 14.Flexible member 12 is to be made up of fixed part 121 and two semielliptic springs 122.Fixed part 121 is to be fixed in ink cartridges 1 inner and upper, and 122 of two semielliptic springs are incorporated into fixed part 121 two ends respectively.Flexible air-bag 14 is a bag shaped structure, and it has passage 143, first side 141 and second side 142.Wherein passage 143 is to become conducting state with ambient atmosphere, and first side 141 is the outside that is incorporated into semielliptic spring 122.
But along with the ink of ink cartridges 1 inside reduces gradually, the flexible air-bag of pressure sensitive structure 10 is also increasing, and the deflection of semielliptic spring 122 also increases thereupon, and wherein these semielliptic spring 122 topmost function series produce negative pressure to avoid taking place the phenomenon that ink exosmoses by its distortion to ink cartridges 1 inside.
Yet above-mentioned pressure sensitive structure 10 still has a lot of problems to be overcome when implementing.The known semielliptic spring that technology provided 122 also can't provide fixing elastic constant; when the deflection of semielliptic spring 122 big more; the negative pressure Pb that it produced is also just big more; in case during the pressure that the negative pressure Pb of ink cartridges 1 inside can provide greater than printhead; it will make printhead can't spray ink; cause to carry out printing function; at this moment; the ink of ink cartridges 1 inside does not also use up usually fully; thereby cause the ink waste; reduce 1 service life of ink cartridges, increase user's burden economically.
