Description
Technical field
The utility model relates to the device that cartridge of ink-jet printer is added ink injection, relates in particular to the injection ink device that has check valve on a kind of piston.
Background technology
Print cartridge is as a kind of consumptive material of printer, and is discarded mostly after the ink in print cartridge used up in the past, caused the pollution to environment, the waste of resource.Now increasing people and enterprise begin to pay attention to the recycling to print cartridge, utilize again behind the ink that reinjects in using up the empty cartridge of ink.Some are injected in the print cartridge after with the syringe pump ink, also are easy to take place ink leakage but compare trouble like this, pollute.
The utility model content
The utility model provides a kind of simple in structure, and it is convenient to add China ink, when adding ink injection, the injection ink device of check valve can not take place to have on the piston of ink leakage.
In order to achieve the above object, the utility model is achieved through the following technical solutions: comprise the storage ink container that is used for storage ink, bottom at the storage ink container is shaped on and adds the ink filling port that black interface is connected, ink filling port communicates with the storage ink container, be provided with the cavity of column on the top of storage ink container, cavity is connected with the storage ink container, the bottom of cavity is equipped with the compression spring, above the compression spring piston is installed, on the storage ink container relative, be with plug connector with piston, be shaped on push rod on the plug connector, push rod faces piston, only on ink filling port, be provided with and permitted the black check valve that goes out that ink comes out, it is characterized in that on piston, being provided with and only permitted extraneous air and enter the breather check valve that stores up in the ink container.
The injection ink device that has check valve on the piston according to the such scheme manufacturing, in use, as long as the ink filling port that will store up ink container with add black interface and be connected after, pressurize to plug connector, promote piston with the push rod on the plug connector, piston is pushed in the cavity, make in the storage ink container and produce pressure, breather check valve is closed, and ink extrudes from ink filling port through going out black check valve.When decontroling plug connector, the compression spring in the cavity is released piston and push rod again, produces negative pressure in the storage ink container, goes out black closed check valve, and breather check valve is closed and opened, and air inlet makes storage ink container inside and outside air pressure balance in the storage ink container.To the plug connector pressurization, realize the refilling of circulation next time again.Push plug connector by such repeated multiple times, till ink is filled it up with in print cartridge.Print cartridge after filling can install on the printer again have been reused.It is very convenient to add China ink.

The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
Fig. 1, Fig. 2 are the structural representations of storage ink container.It comprises the storage ink container 2 that is used for storage ink 1, described storage ink container 2 by top by opening box body 3 and the lid 4 that covers on box body 3 openings form, box body 3 and lid 4 are tightly connected, the bottom of storage ink container 2 is shaped on and adds the ink filling port 6 that black interface 5 is connected, only in ink filling port 6, be equipped with and permitted the black check valve 7 that goes out that ink comes out, sealing ring or sealing shroud 8 are installed on the ink filling port 6.Ink filling port 6 communicates in the ink container 2 with storage, be provided with the cavity 9 of column in the storage ink container 2, cavity 9 is connected in the ink container 2 with storage, the bottom of cavity 9 is equipped with compression spring 10, above the compression spring 10 piston 11 is installed, only establishing perhaps on the piston 11, extraneous air enters the breather check valve 12 that stores up in the ink container 2.Before use, 13 sealings of cavity 9 usefulness diaphragm seals prevent that ink 1 from leaking.On the storage ink container 2 relative with piston 11 plug connector 14 is installed, plug connector 14 is socketed on the storage ink container 2.Be shaped on push rod 15 on the plug connector 14, push rod 15 faces piston 11, and the head of push rod 15 is shaped on air inlet duct or the air admission hole 17 that communicates with the air admission hole 16 of breather check valve 12.Make when piston 11 contacts with push rod 15 heads that the air admission hole 16 that remains breather check valve 12 is unimpeded and can air inlet.When being assembled together with plug connector 14, storage ink container 2 forms the injection ink device that has check valve on the piston.Described go out black check valve 7 and breather check valve 12 structures roughly the same, make with rubber, its head is shaped on the tubular body that cut 18 can open and close.Just breather check valve 12 fuses with piston 11.Certainly do not get rid of the check valve that uses other versions yet.
In use, as long as the ink filling port 6 that will store up ink container 2 with add black interface 5 and be connected after, to plug connector 14 pressurizations, promote pistons 11 with the push rod on the plug connector 14 15, piston 11 is pushed in the cavity 9 as shown in Figure 3, make in the storage ink container 2 and produce pressure, breather check valve 12 is closed as shown in Figure 4, go out black check valve 7 and open as shown in Figure 5, ink 1 extrudes from ink filling port 6 through going out black check valve 7, realizes adding the effect of ink injection.When decontroling plug connector 14, compression spring 10 in the cavity 9 is released piston 11 and push rod 15 as shown in Figure 6 again, produce negative pressure in the storage ink container 2, going out black check valve 7 closes as shown in Figure 7, breather check valve 12 is closed and is opened as shown in Figure 8, by air admission hole 16 air inlets, make the inside and outside air pressure balance of storage ink container 2 in the storage ink container 2.
