Description of drawings
Fig. 1 is the sketch map of the utility model embodiment.
The specific embodiment
Referring to Fig. 1; The continuous ink-supply system of present embodiment comprises head cartridge 1 that is installed in the printer and the ink supply bottle 3 that is placed on printer; Head cartridge 1 original state is not contain ink, but accommodates sponge 12 in the black chamber, and bottom, black chamber has ink outlet port 14.Also be provided with ink filling port 15 on the head cartridge 1, this ink filling port 15 is processed by the original gas port of print cartridge.This ink filling port 15 is tightly connected with the first end of ink-feeding tube 2.The second end of ink-feeding tube 2 is tightly connected with the ink supply port 31 that is arranged at ink supply bottle 3 bottoms.Accommodate ink in the ink supply bottle 3, its capacity several times even number decuple the ink capacity of head cartridge 1.The top of ink supply bottle 3 is provided with gas port 32 and irritates China ink mouth 33.Gas port 32 with irritate China ink mouthfuls 33 liquid levels of inks in ink supply bottle 3 certain spacing arranged, its objective is that the liquid avoided in the ink supply bottle is drawn out of in follow-up process of taking out negative pressure.
The manufacturing approach of this continuous ink-supply system is following: an appendix 4 is provided, the first end of appendix 4 is tightly connected with irritating China ink mouthfuls 33, the second end and a filter chamber 5 are tightly connected, and the bleeding point of a filter chamber 5 and a negative pressure generation device is tightly connected.That is, said bleeding point, filter chamber 5, appendix 4 are tightly connected with filling China ink mouth 33 successively, and said filter chamber 5 is sealedly connected between said ink supply bottle 3 and the said negative pressure generation device.This negative pressure generation device can perhaps other have instrument or the equipment that produces negative pressure with professional vavuum pump, minipump.In the present embodiment, this negative pressure generation device is a minipump 6.This minipump 6 can pass through computer USB interface or cell-phone charging power devices, and supply voltage is 5V.With the ink outlet port 14 on the black box 13 sealing head cartridges, and,, can omit this step if ink outlet port 14 has been in sealing state with gas port 32 with the gas port 32 of sealing film sealing ink supply bottle.Start minipump 6; Because the inner chamber of continuous ink-supply system is complete and ambient atmosphere is isolated; Therefore; Gas in gas in the ink supply bottle 3 and the head cartridge 1 is drawn out of cavity gradually through irritating China ink mouth 33, and the impurity such as ink that contained in the air of extracting out will be filtered in filter chamber 5.When the negative pressure value in the cavity reaches predetermined value, stop to take out negative pressure.In this preferred embodiment, when negative pressure value reaches 60Kpa, stop to take out negative pressure.Then with the disconnection that is tightly connected between appendix 4 and the filling China ink mouth 33; At this moment; Irritate China ink mouth 33 and be exposed in the atmosphere, because atmospheric effect, the part ink in the ink supply bottle is pressed in the head cartridge 1 through ink-feeding tube 2; The ink that is pressed into can occupy the space of the gas that is drawn out of, and should irritate China ink mouth 33 with sealing the plug sealing afterwards.After above-mentioned steps was accomplished, the user only need remove the seal 13 of ink outlet port 14, removes the sealing film of gas port 32 simultaneously, and print cartridge 1 is installed in the print cartridge resettlement section in the PRN device, and this continuous ink-supply system gets final product operate as normal.According to the continuous ink-supply system of manufacturing of the present invention, air residual in its print cartridge is less, has so just reduced the possibility that produces the hickie phenomenon when printing.
In above-mentioned manufacture process, can change from the opening that the ink supply bottle is taken out negative pressure and unloaded negative pressure.For example, the first end of appendix and the gas port of ink supply bottle are tightly connected, and use the filling China ink mouth of sealing plug sealing ink supply bottle, then the negative pressure generation device just can be taken out negative pressure and the operation of unloading negative pressure from gas port.For example offer an opening again on the top of ink supply bottle, the first end of appendix and the opening of newly opening are tightly connected, and sealing simultaneously irritates China ink mouthful and gas port, then the negative pressure generation device just can be taken out negative pressure and unload the operation of negative pressure from this opening of newly opening.
In addition, existing part ink supply bottle structure, its top has only an opening, and this opening both can realize irritating the function of China ink mouth, also can realize the function of gas port.For the continuous ink-supply system of this structure, in manufacture process, only need with the first end of appendix therewith opening be tightly connected, the negative pressure generation device just can be taken out negative pressure and unload the operation of negative pressure.
In above-mentioned manufacture process, take out the negative pressure value of negative pressure and can select.Negative pressure value preferred for this invention is-60KPa that its reason is: at first, minipump commonly used can reach the negative pressure value of 60Kpa easily; Secondly; Because taking out negative pressure is a process, to take out in the process of negative pressure at this, the gas in the print cartridge is to discharge gradually, when negative pressure value reaches 60KPa, can guarantee exhaust effect preferably.Certainly, according to result of experiment repeatedly, when the scope of negative pressure value at-50Kpa between-the 100Kpa time, all can realize the object of the invention.And negative pressure value surpasses-during 60Kpa and approaching-100Kpa, exhaust effect is no doubt better, but the material of ink supply bottle and print cartridge is required also higher, otherwise excessive negative pressure possibly cause the distortion even the damage of ink supply bottle or print cartridge.On the other hand, when negative pressure value during much smaller than-60Kpa, exhaust effect is not obvious, still residual more gas in the print cartridge, and the phenomenon of printing hickie still can compare frequently.In sum, to-100Kpa, preferred negative pressure value is-60Kpa the scope of the preferred negative pressure value of the present invention at-50Kpa.
