Split type ink-jet printer cartridge
Technical field
The present invention relates to a kind of ink-jet printer cartridge, relate in particular to a kind of split type ink-cases of printers.
Background technology
The structure of existing printer print cartridge generally is to include the ink cartridge that holds ink, also comprise and be arranged at the maintenance body of wherein preserving ink, as sponge etc., the main order of ink keeping body is, when printing, the carrier of printer drives print cartridge repeatedly in the moving process, make because of violent the movement and produce bubble in the ink, the ink that contains bubble is during to printer ink-providing, bubble can make ink produce broken string, the fatal problem that thereby can cause typewrites fades, in order to prevent the phenomenon that typewriting is faded, general attract also to preserve ink with porous plastid such as mephenesin Carbamate sponge or nonwoven, realize that only supplying with ink by the ink supply material does not contain bubble and make the guaranteed purpose of print quality; In addition, on the basis of these structures, make the ink more mobile and stable purpose to printer ink-providing that continues in order to reach, taked the make of diversified ink keeping body, wherein, existing environment has any variation can not produce the print cartridge of bubble, is ink to be injected after adopting flexible film's contraction bag that air is got rid of fully to form the print cartridge packing again; And porous plastid generally is to be representative with the sponge of being made up of tiny tissue, and nonwoven etc. also is widely used in addition; What generally be used steeps the carbamic acid sponge material of forming by tiny company, and frothing percentage is being widely used below 50%; The use porous plastid particularly connects the purpose of steeping sponge and is, sponge is being full of under the state of ink, along with the ink in the consumption spongy tissue of ink will move, the generation pressure imbalance has produced negative pressure along with the movement of ink so the pressure in the fine tissue diminishes, thereby keeps making ink can stablize mobile kilter; As making this state keep stable a kind of means, can change according to the pressure in the consumption spongy tissue of ink, organize the more little induction that becomes more quick, even have only the variation of any also can perceive, so perceptibility is very high, thereby put into very effective after in ink accommodation section and ink conveying unit, spongy tissue compression being diminished; But, with the method for putting into after the porous plastid compression, very difficult in operation, the arrangement of organizing the back is put in compression can not be even, in general, and with the porous plastid compressed container, even want inside is full of ink, but capacity be only limited to sponge be full of capacity, if can not be at the part storage ink beyond the sponge, drawback be arranged still on efficient; This mode wants that the ink full consumption with porous plastid the inside is impossible, and ink is filled to the print cartridge of the mode in the porous plastid, also has the fact that just can not print use under 30% the situation to exist in residual amount; In addition, all be that collection function and body are the structure of one as the basic configuration of general print cartridge, want all series, the print cartridge of kind is all showed, just needs the mould of investment all kinds print cartridge, makes production cost that certain pressure be arranged; About the flow route of ink in the print cartridge, so because the structure of the very complicated print cartridge of its theory also becomes complicated, the cost of producing aspects such as equipment purchasing in man-hour has all been strengthened; Again because the porous plastid that is widely used at present, the theory from the retentivity of ink with the mode of the different material plural number combination of the transitivity of ink, adds that the particularity of material causes cost to increase, and also acquires a certain degree of difficulty in the buying; After filling with ink in the print cartridge, in order to prevent under the ink droplet or the state of ink spattering, before sealing, to prevent with corresponding equipment, can increase manufacturing facilities like this, say it also is undesirable originally for producing, having filled the goods behind the ink, to put storage all stable inadequately basically, so need deposit the apparatus that goods are used specially, aspect production efficiency, also have many problems; And, because want to hold after compressed reason to container, just formed the key factor of the ink of can in a large number but this ink cartridge is when loading, be provided with the fixedly screens that ink cartridge is connected to the integral type on the printer in ink cartridge one side, after using at every turn, print cartridge needs to reclaim again, cause the waste of resource, simultaneously, the material cost of making print cartridge also can increase, and for different printer models, fixedly screens and print cartridge all are to need different moulds, also are a kind of invisible increases for R﹠D costs.
