Detailed description of the invention
Further understand for making to have architectural feature of the present invention and effect of reaching and be familiar with, coordinate detailed description in order to preferred embodiment and accompanying drawing, 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 receptive chamber 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 receptive chamber 1 and negative pressure generation part container cavity 2 are interconnected by connectivity slot 4;
Ink receptive chamber 1 and negative pressure generation part container cavity 2 are sealed by cover 9; Be provided with blotting material 5 in negative pressure generation part container cavity 2, ink outlet port 3 place is provided with filter tip 6 out of ink;
As improvement of the present invention, blotting material 5 and filter tip out of ink 6 are made up of integrated porous material, and this porous material has density gradient from top to bottom, and the density of ink outlet port 3 place material is the highest.
Preferably, the cross section of negative pressure generation part container cavity 2 reduces from top to bottom gradually.
Preferably, bottom porous material, 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 not having external force.
Preferably, the 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 open to atmosphere gas port 8 of surge chamber 7 company of being provided with.
The shape of this integral type porous material and the interior shape of 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, between the foot density of porous material is 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 assembled vacuumizes in the ink receptive chamber of backward print cartridge and pours into ink, and the connectivity slot 4 of part ink bottom negative pressure generation part container cavity 2 and ink receptive chamber 1 flow to negative pressure generation part container cavity 2 side from side, ink receptive chamber 1 and absorbed by porous material.When print cartridge is installed to after on printer, along with ink exports from ink outlet port 3 by printhead, the ink infiltrated in integral type porous material constantly reduces, due to the capillary force of material, ink in ink receptive chamber 1 is constantly transferred in integral type porous material, negative pressure in ink receptive chamber 1 is raised, when this negative pressure constantly increases, the ink level infiltrating integral type porous material declines thereupon, now, extraneous gas can enter in negative pressure generation part container cavity 2 through surge chamber 7 along gas port 8, until after having bubble to enter ink receptive chamber 1 from negative pressure generation part container cavity 2 by connectivity slot 4, negative pressure in ink receptive chamber 1 reduces thereupon, and reach balance, such reciprocation cycle, until ink has been printed.
Embodiment 2
As Fig. 2, Fig. 2 a, shown in Fig. 2 b, the ink-cases of printers of the present embodiment comprises ink receptive chamber and negative pressure generation part container cavity, ink outlet port bottom negative pressure generation part container cavity, ink receptive chamber 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 arranged in negative pressure generation part container cavity and ink outlet port place are arranged is integral type porous material, the incompressible intensity of its left and right directions of this material is lower, above-below direction and the incompressible intensity of fore-and-aft direction higher, therefore its left and right directions comparatively up and down and back and forth direction 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 more and more less container cavity bottom of cross-sectional area, material is compressed in left-right 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 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 one.
Embodiment 3
As shown in Fig. 3, Fig. 3 a, Fig. 3 b, this embodiment is similar to embodiment two, difference is the integral type porous material that the filter tip out of ink of blotting material and the ink outlet port place setting arranged in negative pressure generation part container cavity forms, the incompressible intensity of its fore-and-aft direction of this material is lower in this embodiment, above-below direction and the incompressible intensity of left and right directions higher, therefore its fore-and-aft direction comparatively up and down and left and right directions easily compressed, the density of this integral type porous material is uniform before print cartridge assembling, and 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 more and more less container cavity bottom of cross-sectional area, material is compressed along the longitudinal 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 one.
Three embodiments described in the invention are with the print cartridge with surge chamber; according to actual conditions; the present invention also can remove surge chamber; directly be communicated with air by negative pressure generation part container cavity; the relation that arranges and the operation principle of the miscellaneous part of print cartridge are all same as the previously described embodiments, and this print cartridge without surge chamber also should drop in protection scope of the present invention.
Above detailed description of the invention is only the preferred embodiment of this creation, and not in order to limit this creation, any amendment made within all spirit in this creation and principle, equivalent replacement, improvement etc., within the protection domain that all should be included in this creation.
