The bottom of upper casing 3 also is provided with can be along the axially movable ink-filling needle baffle 39 of ink-filling needle 33, has on this ink-filling needle baffle 39 to supply ink-filling needle 33 through hole 391 that passes and the slit 392 that can supply said limiting plate 381 to pass.The bottom surface of roof 31 is fixed on the top that also is provided with 382, two guide pillars 382 of two guide pillars that cooperate with ink-filling needle baffle 39 in the upper casing 3, is with the spring 37 between ink-filling needle baffle 39 and roof 31 respectively on two guide pillars 382.This ink-filling needle baffle 39 can be avoided ink-filling needle 33 to expose in the installation process of ink-filling device hurting sb.'s feelings, use safer.
The bottom surface of said ink-filling needle baffle 39 is provided with the detent 393 that can cooperate with the locating convex block 14 at print cartridge 1 top.In addition, also be provided with the seal 35 of the pouring ink hole 11 at sealing print cartridge 1 top when being used in refilling in the bottom of ink-filling needle baffle 39.
Said base 2 is provided with the groove 22 that cooperates with the nozzle 12 of print cartridge 1, and the bottom of this groove 22 is fixed with the silicagel pad 23 that is used for sealed-in nozzles 12 when refilling.The both upper ends thereof side of base 2 respectively is provided with a fastener 21, respectively has a button hole that can cooperate with said button bit 36 on each fastener 21.
Negative pressure injection ink device 4 comprises transparent urceolus 41 and the push rod 42 that can in this urceolus 41, move back and forth, and this push rod 42 can be hollow push rod, and the cavity 421 in it is connected with the inner chamber 411 of urceolus 41; Certainly, this push rod also can be the hollow push rod of solid push rod or lower end closed.Said urceolus 41 is provided with two and is used to weigh the mark line of taking out the negative pressure amount, and first mark line 43 is positioned at the top of urceolus 41, and second mark line 44 is positioned at the middle part of urceolus 41.
Referring to Fig. 5 to Figure 10, the method for using of above-mentioned ink-filling device is following:
1, is mounted to upper casing 3 to print cartridge 1 nozzle up, during installation, with the locating convex block 14 at print cartridge 1 top and detent 393 positioned in alignment of ink-filling needle baffle 39 bottom surfaces.
2, overcome the resistance of spring 37; Print cartridge 1 is pressed in the print cartridge container cavity 38 of upper casing 3; In the process of press in; Ink-filling needle 33 on the upper casing 3 is inserted in the ink storage chamber 13 of print cartridge 1, and the 381 pairs of print cartridges 1 of polylith limiting plate on upper casing 3 sidewalls 32 inner surfaces play effect spacing and guiding, and the seal 35 of ink-filling needle baffle 39 bottoms is with the periphery sealing of the pouring ink hole 11 at print cartridge 1 top.
3, after print cartridge 1 is loaded into print cartridge container cavity 38, base 2 is installed on the upper casing 3.And be anchored to the fastener 21 of base 2 on the button bit 36 of upper casing 3, the silicagel pad 23 in the base 2 just in time corresponding to the nozzle 12 of print cartridge 1 with its sealing.
4, upper casing 3 is turned, make its refilling interface 34 up.
5, be inserted into the negative pressure injection ink device 4 that ink is housed in advance on the refilling interface 34 of upper casing 3; Pull up the push rod 42 of negative pressure injection ink device 4; Release the gas in the ink storage chamber 13 of print cartridge 1; Ink about 1/3rd (20 grams) is housed in the urceolus 41 of negative pressure injection ink device 4 in advance, can sees having bubble to rise, be illustrated in ink storage chamber 13 is taken out negative pressure.Like Figure 10; Because print cartridge 1 is the print cartridge of half sponge structure, the ink adsorbance of its sponge is less, and it is also less therefore need to take out the negative pressure amount; Only need align to the push rod 42 lower ends position of second mark line 44 of push rod 42 pulls; Can unclamp the push rod 42 of negative pressure injection ink device 4, this moment, push rod 42 walked downward under the atmospheric pressure in the external world, and the ink in the negative pressure injection ink device 4 also is forced in the inking chamber 13 of print cartridge 1.After refilling was accomplished, the sponge in the print cartridge 1 did not reach supersaturation, can adsorb ink, did not have ink and spilt from the nozzle of print cartridge 1.
6, like Figure 11; When the print cartridge 10 to full sponge structure carries out refilling,, therefore can extract bigger negative pressure amount because the ink adsorbance of its sponge is bigger; Can be during concrete operations align to the push rod 42 lower ends position of first mark line 43 of push rod 42 pulls; Unclamp the push rod 42 of negative pressure injection ink device 4 then, this moment, push rod 42 walked downward under the atmospheric pressure in the external world, and the ink in the negative pressure injection ink device 4 also is forced in the inking chamber of print cartridge 10.
Above-described only is the preferred implementation of the utility model, should be pointed out that for the person of ordinary skill of the art; Under the prerequisite that does not break away from the utility model inventive concept; Can also make some distortion and improvement, for example, the mark line on the negative pressure injection ink device can also be arranged on the push rod; The quantity of mark line also is not limited to two; Can be more than one or three, the position of mark line also can be provided with according to actual needs flexibly, and these all belong to the protection domain of the utility model.
