Abstract
A printer ink cartridge comprises an ink accommodating cavity and a negative pressure generation part accommodating cavity. An ink outlet is arranged in the bottom part of the negative pressure generation part accommodating cavity along the gravity direction. The ink accommodating cavity and the negative pressure generation part accommodating cavity are communicated with each other in the bottom part. The cross sectional area of the negative pressure generation part accommodating cavity gradually decreases from the top to the bottom. A material filled in the negative pressure generation part accommodating cavity and the ink outlet is an integrally-molded porous material, and the material forms a density gradient from the top to the bottom. The material in the place of the ink outlet is highest in density and serves as an ink outlet filter. The printer ink cartridge is simple in structure, reliable in performance, large in ink capacity, low in cost, and convenient to manufacture.

The specific embodiment
For making that architectural feature of the present utility model and the effect reached are had and further understand and be familiar with, in order to preferred embodiment and accompanying drawing, coordinate detailed explanation, be described as follows:
Embodiment 1
As shown in Fig. 1, Fig. 1 a, Fig. 1 b, a kind of ink-cases of printers, comprise ink container cavity 1 and negative pressure generation part container cavity 2, negative pressure generation part container cavity 2 is provided with ink outlet port 3 along the bottom of gravity direction, and ink container cavity 1 is interconnected by connectivity slot 4 with negative pressure generation part container cavity 2;
Ink container cavity 1 and negative pressure generation part container cavity 2 are sealed by cover 9; In negative pressure generation part container cavity 2, be provided with blotting material 5, ink outlet port 3 places are provided with filter tip 6 out of ink;
As improvement of the present utility model, blotting material 5 and filter tip out of ink 6 are made by integrated porous material, and this porous material has density gradient from top to bottom, and the density of ink outlet port 3 place's materials is the highest.
Preferably, the cross section of negative pressure generation part container cavity 2 reduces from top to bottom gradually.
Preferably, porous material bottom density is 1.25 times-5 times of top density, and best between 1.5 times to 3 times, porous material just can be infiltrated by ink under the effect that there is no external force.
Preferably, a side of negative pressure generation part container cavity 2 is also provided with surge chamber 7, and this surge chamber 7 is communicated with negative pressure generation part container cavity 2.
Preferably, the surge chamber 7 open to atmosphere gas ports 8 of the company of being provided with.
The interior shape of the shape of this integral type porous material and negative pressure generation part container cavity 2 and ink outlet port 3 coincide, therefore can assemble easily and efficiently, this integral type porous material forms density gradient from top to bottom, the foot density of porous material is between 1.25 times to 5 times of topmost density, more suitably between 1.5 times to 3 times, preferably be between 1.8 times to 2.5 times.
Preferably, the density of material topmost is between every cubic metre 50 kilograms to 200 kilograms, and the density of material foot is between every cubic metre 100 kilograms to 400 kilograms, and the density of material foot is 1.8-2.5 times of material topmost density.
The print cartridge assembling vacuumizes in the ink container cavity of backward print cartridge and pours into ink, part ink through the connectivity slot 4 of negative pressure generation part container cavity 2 and ink container cavity 1 bottom from ink container cavity 1 one side flow to negative pressure generation part container cavity 2 one sides and absorbed by porous material.After print cartridge is installed on printer, along with printhead is exported ink from ink outlet port 3, the ink infiltrating in integral type porous material constantly reduces, capillary force due to material, ink in ink container cavity 1 is constantly transferred in integral type porous material, negative pressure in ink container cavity 1 is raise, when this negative pressure constantly increases, the ink level that infiltrates integral type porous material declines thereupon, now, extraneous gas can be along gas port 8 in surge chamber 7 enters into negative pressure generation part container cavity 2, until there is bubble to enter ink container cavity 1 by connectivity slot 4 from negative pressure generation part container cavity 2, negative pressure in ink container cavity 1 reduces thereupon, and reach balance, reciprocation cycle like this, until ink has been printed.
As Fig. 2, Fig. 2 a, shown in Fig. 2 b, the ink-cases of printers of the present embodiment comprises ink container cavity and negative pressure generation part container cavity, negative pressure generation part container cavity bottom is ink outlet port, ink container cavity is communicated with negative pressure generation part container cavity, the cross-sectional area of negative pressure generation part container cavity reduces from top to bottom gradually, the filter tip out of ink that the blotting material arranging in negative pressure generation part container cavity and ink outlet port place arrange is integral type porous material, the incompressible intensity of its left and right directions of this material is lower, the incompressible intensity of above-below direction and fore-and-aft direction is higher, so its left and right directions is upper and lower and fore-and-aft direction is easily compressed, the density of this integral type porous material is uniform before print cartridge assembling, its density is between every cubic metre 50 kilograms to 200 kilograms.During print cartridge assembling, material inserts negative pressure generating unit container cavity from top, along with material enters the container cavity bottom that cross-sectional area is more and more less, material is compressed along left and right directions, density uprises, after result makes assembling, this integral type porous material forms density gradient, and top density is low, and bottom density is high, and automatically forming filter tip out of ink at ink outlet port, the foot density of having assembled rear integral type porous material is 1.25-2.5 times of its topmost density.The operation principle of having assembled rear print cartridge is identical with the print cartridge of embodiment mono-.
As shown in Fig. 3, Fig. 3 a, Fig. 3 b, this embodiment is similar to embodiment bis-, difference is the integral type porous material that the blotting material of setting in negative pressure generation part container cavity and the filter tip out of ink that ink outlet port place arranges form, the incompressible intensity of its fore-and-aft direction of this material is lower in this embodiment, the incompressible intensity of above-below direction and left and right directions is higher, so its fore-and-aft direction is upper and lower and left and right directions is easily compressed, the density of this integral type porous material is that its density is between every cubic metre 50 kilograms to 200 kilograms uniformly before print cartridge assembling.During print cartridge assembling, material inserts negative pressure generating unit container cavity from top, along with material enters the container cavity bottom that cross-sectional area is more and more less, material is compressed along fore-and-aft direction, density uprises, after result makes assembling, this integral type porous material forms density gradient, and top density is low, and bottom density is high, and automatically forming filter tip at ink outlet port, the foot density of having assembled rear integral type porous material is 1.25-2.5 times of its topmost density.The operation principle of having assembled rear print cartridge is identical with the print cartridge of embodiment mono-.
