The printing expense of users can be decreased, and the environment can be favored. With simple structure, the utility model can be installed conveniently.

Description

Split type print cartridge

Affiliated technical field

The utility model relates to printer, particularly ink-jet printer cartridge

Background technology

In some inkjet technology, print cartridge is defined as and can only disposablely uses, and its structure and default chip make it can't add ink, also can't continue to use.Print cartridge after using up both was dropped, working of plastics wherein, and residual ink and chip can not be by natural degradations; And the user must purchase new print cartridge printer is normally used.This mode had both produced environment to be polluted, and has increased user's printing expense again.Differentiate piece and print cartridge latch segment and more increased color on the print cartridge of some kind, so, the complexity of product has increased, and production cost also increases thereupon, and for the user, the printing expense is more also big.

The utility model content

In order to overcome ink-jet box cost height, the user prints the big shortcoming of expense, can alleviate environmental pollution problems again simultaneously, and the utility model provides a kind of split type print cartridge, and it can reduce the user and print expense, and also can reduce the pollution to environment simultaneously.

The technical scheme in the invention for solving the technical problem is: a kind of split type print cartridge, comprise ink storage chamber, chip and latch segment, it is characterized in that: ink cartridge and framework are respectively independent products, have chip and latch segment on the framework, be shaped on ink container and pressure equaliser in the ink cartridge, ink cartridge removably is connected on the framework.

The beneficial effects of the utility model are: can reduce the user and print expense, and help environment.Simultaneously simple in structure, easy for installation.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

1 framework among the figure, 2 ink cartridges, 3 differentiate piece, 4 chips, 5 films, 6 latch segments, 7 ink outlet ports, 8 joint pins, 9 connecting holes, 10 ink containers, 11 air inlet pipe, 12 tear tapes, 13 anti-overflow pads, 14 connecting leg valves, 15 valve ports, 16 screen packs.

The specific embodiment

As seen assemble the split type print cartridge of finishing among Fig. 1, mainly comprised framework 1 and ink cartridge 2.Assembled chip 4 on the framework 1 and differentiated piece 3, when print cartridge was installed, discriminating piece 3 can be found the position of print cartridge correspondence accurately, and is unlikely to take place the situation that ink is scurried look.Side in framework 1 has latch segment 6, and it can cooperate with corresponding mechanism on the printer when installation, makes ink outlet port 7 that good sealing can be arranged, and print cartridge is not become flexible.Tear tape 12 plays the effect of sealing passage in transportation and storing process, only need it is just torn off and can normally use before the print cartridge installation.

Shown the most of member of split type print cartridge among Fig. 2, can see also to have many joint pins 8 on the framework 1 that it can match with the connecting hole 9 on the ink cartridge 1, and both are combined closely.After the ink in the ink cartridge 2 uses up, can apply certain power to the place of joint pin 8 and connecting hole 9 combinations, both cooperations are got loose, so that change ink cartridge 2.Framework 1 then need not to change, as long as cooperate new ink cartridge 2 just can repetitive cycling to use.This structure decrease the working of plastics and the chip that must abandon, thereby help environmental protection.

Anti-overflow pad 13 is a kind of thin materials that can absorb liquid, resembles nonwoven, the cotton paper plate, and it is positioned between framework 1 and the ink cartridge 2.Because during various fortuitous event generation spill and leakage, anti-overflow pad 13 can and keep ink absorption, in order to avoid inkiness is to other place when ink.

Film 5 is generally made with plastic material, by specific adhesion technique it is bonded on one or more sides of ink cartridge 2, makes ink cartridge 2 except that ink outlet port 7, fully sealing back storage ink.

Fig. 3 shows the planar structure of ink cartridge 2, and its inner space is exactly ink storage chamber.Connecting leg valve 14 is check valves of an elastic material (as rubber, silica gel), and an end is connected on the ink cartridge 2, and corresponding to passage.When ink was printed machine and consumes gradually, air entered in the ink cartridge 2 by connecting leg valve 14, to keep box internal pressure balance.In the bottom of connecting leg valve 14, there is one to be slot-shaped valve port 15 (see figure 4)s, it is designed to and can only opens valve towards a direction, so that air enters into ink cartridge 2 inside, ink then can't be by it to external leakage.

Also have ink container 10 in ink cartridge 2, it is in the form of annular discs, and is provided with an ink channel.Ink can be drawn into gradually in the ink container 10 and be supplied to printer nozzle during work.Also be provided with a screen pack 16 in the ink container 10, it can play the effect of filtering ink when printing, prevent that impurity from entering printer, causes adverse effect.One screen pack 16 is also arranged at the bottom of ink container 10, can filter ink equally.Two screen packs 16 all communicate with ink outlet port 7, can guarantee that all inks that flow to printer all are filtered one time.Two screen pack 16 residing height and position differences can be with different isostasies, to offer printer stable ink pressure.

Fig. 5 has provided the schematic diagram of tear tape 12, and the one side that it contacts with ink box cover bonds together by heat seal, and remainder is after folding, and is protruding.Before machine work on the print cartridge, tear tape 12 must be thrown off.As seen from the figure, the tear tape 12 after folding can be thrown off convenient and strength-savingly.

Fig. 6, Fig. 7, Fig. 8 have expressed the split type print cartridge of another model, also are another embodiment of the present utility model simultaneously.A print cartridge profile and a last embodiment are different as seen from the figure, and a limit that tilts is arranged at the top of framework 1, differentiate that the shape of piece 3 is bigger, another side in the installation site of chip 4 is also changed to.These are changed all is in order to cooperate the printer of different model, to be beneficial to install and normal the use.At ink cartridge 2 in-discards connecting leg valve 14, and directly connect atmosphere with an air inlet pipe 11.A breather check valve can certainly be connect in the bottom of air inlet pipe 11 again, so also original designing requirement can be reached fully.Joint pin 8 among the figure, and different with last embodiment shape with connecting hole 9, they all are to cooperatively interact with round-shaped, finish to connect two-part purpose.

Although air inlet pipe 11 is different with the structure of connecting leg valve 14, they all are pressure equalisers, all serve the same role.

Need to prove that connected mode does not terminate in joint pin 8 described above and connecting hole 9.Many modes that are connected and fixed commonly used, such as: screw, double faced adhesive tape, adhesive tape, hasp, or the like, can easily framework 1 and ink cartridge 2 be connected and fixed, and allow dismounting, do not describe one by one here.

Ink cartridge 2 also can be two-sided open-minded, and both-sided adhesive film 5 can hold more ink like this in ink cartridge 2 simultaneously.
