Description
Technical field
The present invention relates to a kind of print cartridge that is used for ink-jet printer, pressure adjustmenting mechanism in particularly a kind of print cartridge, this print cartridge can adapt to that varying environment changes in case the leak-stopping China ink, and when the ink in the print cartridge reduces, still can adjust the back pressure in the print cartridge, ink can be flowed out smoothly.
Background technology
Existing computer printer is general on the market can be divided into three kinds approximately: line dot matrx, ink-jet printer and laser printer.Though the line dot matrx low price is its mortal wound yet its print speed is slow, print quality is not good, so that can't on market, compete mutually with ink-jet or laser printer, thereby the scope of application only limits to particular range.Now on the market ink-jet or laser printers of using more, this the two performance respectively has quality, and for example: the ink-jet printer purchasing price is comparatively cheap, but its print cost and consumptive material then higher, otherwise the laser printer purchasing price is higher, but its printing cost and consumptive material are then comparatively cheap.In addition, the use of laser printer is confined to black and white more and prints (high because of the color laser printer unit price, as how to use with printout before the high-order seal).Otherwise for ink-jet printer, it can be used for black and white or colour print, and because its pixel precision significantly increases (by 300dpi to 1200dpi), the therefore general demand ratio that uses is in quick increase.Yet how the print cartridge space limited provides maximum inks, and keeps ink supply smooth and easy to reduce printing and consumables cost, current really ink-jet printer problem demanding prompt solution under various environments for use.
For making limited print cartridge space can have maximum quantity of ink, the simplest design is that ink is filled the card casket, however the change that influences ink supply because of a lot of and wayward, liquid level reduced the variation that causes hydraulic pressure when for example ink used; Temperature, ink constituent and solution impurity are to the coefficient of viscosity, capillary influence; And air pressure, environment atmospheric pressure and Temperature Influence in the print cartridge; And in the influence of dynamic balance under the situation of surface tension of liquid, any one become because of slight variations all can destroy its balance.
In this kind prior art, the U.S. the 5th, 409, No. 134 patents are to provide an air bag that communicates with atmosphere and elastic device to use in the card casket to adjust the poised state of blocking back pressure in the casket; And the 5th, 600, No. 358 patents of the U.S. are that the vent valve of ink leak water not is set in print cartridge bottom, by this when preserving or during the serviceability temperature increase, this vent valve can be injected air and then prevent the seepage that ink is unnecessary by pressure reduction.Yet all too complexity and spare part are too many for aforementioned prior art constructions, cause manufacturing cost significantly to rise.
In addition, the material (as sponge) of the tool water absorbing force of packing into is also arranged, as shown in Figure 1 in the space of print cartridge.Though this kind improves and can the defective that ink leaks outside be remedied, yet the disadvantage of all filling inks can take place to use up fully.
As shown in Figure 1, after filling sponge 21 in the print cartridge 2,, ink 22 tightly can be adsorbed in the sponge 21, prevent that ink 22 from leaking outside downwards because sponge 21 has powerful water absorbing force.Therefore, when dynamic balance, because the adsorption capacity of sponge 21 is greater than the surface tension of ink 22, therefore, its poised state is unlikely to be destroyed easily.Under this situation, see through the absorption affinity that sponge 21 provides, the ink 22 in the print cartridge 2 is just unlikely to leak outside easily, the ink supply pressure that can avoid ink 22 seepages and be maintained fixed.Yet because the volume space in the print cartridge 2 is limited, if therefore filling sponge 21 is in interior, just the quantity of ink that can pour into has reduced.Moreover, because sponge 21 absorbent materials such as grade have absorption affinity, therefore when ink 22 will be used up, have partly that ink can't overcome the sponge absorption affinity and be maintained in the card casket, cause utilizing remaining ink.For example general print cartridge originally can be filled the space of 40g ink, after the sponge of packing into, can only fill the quantity of ink about 30g, but the ink of this 30g is again because the effect of sponge absorption affinity, the ink that causes having about 6-7g can't use, therefore originally can utilize the ink of 40g in theory, what in fact really use has only 23-24g, most unfortunate in the utilization of space and ink.
In addition, because sponge not only has water absorbing force, and because the loose cause of its institutional framework, even if non-dawn ink air etc. all can be adsorbed.Therefore, sponge is understood residual size bubble within it in the print cartridge ink supply, if bubble can't be discharged smoothly, then in printing, meet bubble and just can cause ink feed to have some setbacks, so cause printing interrupt or print colors deep mixed and reduce print quality.
