The specific embodiment
For making that architectural feature of the present invention and the effect reached are had and further understand and be familiar with, coordinate detailed explanation 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 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 by cover 9 sealings; Be provided with blotting material 5 in negative pressure generation part container cavity 2, ink outlet port 3 places are 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 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 also is 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 be assembled 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 1.8-2.5 that the density of material foot is material topmost density doubly.
The print cartridge assembled vacuumizes in the ink container cavity of backward print cartridge and pours into ink, the 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 infiltrated in the integral type porous material constantly reduces, capillary force due to material, ink in ink container cavity 1 is constantly transferred in the integral type porous material, negative pressure in ink container cavity 1 is raise, when this negative pressure constantly increases, the ink level that infiltrates the integral type porous material descends thereupon, now, extraneous gas can be along gas port 8 in surge chamber 7 enters into negative pressure generation part container cavity 2, until having bubble to enter ink container cavity 1 from negative pressure generation part container cavity 2 by connectivity slot 4, 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, the 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 arranged in negative pressure generation part container cavity and ink outlet port place arrange is the 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 the print cartridge assembling, its density is between every cubic metre 50 kilograms to 200 kilograms.During the 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 the 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 the print cartridge assembling.During the 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-.
Three embodiment described in the invention are with the print cartridge with surge chamber; according to actual conditions; the present invention also can remove surge chamber; by negative pressure generation part container cavity, directly with atmosphere, be communicated with; 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.
The above specific embodiment is only the preferred embodiment of this creation, not in order to limit this creation, any modification of making within all spirit in this creation and principle, is equal to replacement, improvement etc., within all should being included in the protection domain of this creation.
