Abstract

Disclosed is an ink box with convenient ink feed, which divides the ink box into a part for filtering supplied ink and a part for storing the ink. The part for filtering the supplied ink is composed of a sponge ink storing chamber, a strain net and an ink outlet provided with a rubber packing ring, the part for storing the ink divides a part of the ink box into an ink storing chamber for storing the ink by using the separator of the ink storing chamber, and the ink storing chamber is provided with a notch on the lower part. The ink in the ink storing chamber is absorbed into the sponge ink storing chamber for standby by adopting capillarity and a communicating vessel theory, and an ink inlet and a rubber bung of the ink inlet are arranged above the ink storing chamber for conveniently feeding the ink. The rubber bung of the ink inlet is opened for conveniently feeding the ink in the time of feeding the ink, the rubber bung of the ink inlet is closed after feeding the ink, and the installation and the usage of the utility model are the same as a common ink box.

Description

The print cartridge that conveniently adds China ink

Affiliated technical field

The utility model relates to a kind of print cartridge of ink-jet printer.

Background technology

At present, the print cartridge of ink-jet printer mostly is disposable print cartridge, and the ink in most of print cartridge can't all utilize, and not only causes waste: but also contaminated environment; Promptly allow to the ink of annotating, also inconvenient.

Summary of the invention

The purpose of this utility model provides a kind of print cartridge that conveniently adds China ink, maybe needs to use vacuum ink feeder just can add the problem of China ink to solve the additional ink inconvenience of common print cartridge.

The technical scheme that the utility model adopted is: print cartridge is divided into filters ink supply and the black chamber two large divisions of storage.Filter the ink outlet port of ink guide part by the band rubber seal, filter screen stand, screen pack, sponge ink storing chamber forms; The ink storage portion branch is to be separated by the part of the black chamber of notched storage, bottom dividing plate with print cartridge.The breach of sponge ink storing chamber through storing black chamber the lower partition communicates with the black chamber of storage; The print cartridge loam cake filter the ink guide part position above leave air-vent, above storage part position, black chamber, ink filling port and ink filling port rubber stopper are arranged, build that the top of the black chamber of storage seals behind the ink filling port rubber stopper.Ink filling port is used for vacuumizing first refilling and replenishes ink to the black chamber of storage later on.Build ink filling port with the ink filling port rubber stopper after the refilling.During ink-jet printer work, air-vent is opened, and sponge ink storing chamber is communicated with atmosphere through air-vent.Like this, the breach of air-vent, sponge ink storing chamber, the black chamber of storage the lower partition with store black chamber and just formed the container that the upper end open bottom links to each other; And the container that the upper end open bottom links to each other is a linker.Because the breach of sponge ink storing chamber through storing black chamber the lower partition communicates with the black chamber of storage, the breach of the black chamber of storage the lower partition is close in the lower end of cavernous body, and the breach of ink through storing black chamber the lower partition that cavernous body will be store in the black chamber because of capillarity sucks cavernous body.According in containing the linker of same liquid, the reason that the pressure of sustained height place each point all equates, the liquid level in the cavernous body constantly rises, till the static pressure of rising fluid column has been offset additional pressure; At this moment reached the equalization point of a static state.Print or clean shower nozzle after the suction ink ejection of sponge ink storing chamber when printer is normal, the liquid level in the cavernous body descends.The breach of cavernous body through storing black chamber the lower partition sucks ink and rises to another equalization point more simultaneously.Because of the black chamber of storage at this moment seals, the height on both sides is different.Like this through repeatedly repeatedly after, when the liquid level in the cavernous body arrives the breach of the black chamber of storage the lower partition, will suck portion of air from the breach of storing black chamber the lower partition in the black chamber of storage, the pressure of storing in the black chamber becomes big, and the liquid level in the cavernous body rises to another new equalization point once again.Circulation so repeatedly, the ink in the black chamber of storage is used up.The ink outlet port and the ink entrance on the inkjet printer head of the down gap of air-vent, sponge ink storing chamber, cavernous body, storage China ink chamber, the black chamber of storage dividing plate, screen pack, band rubber seal have just formed a complete ink feeding system to the inkjet printer head ink supply like this.

The beneficial effects of the utility model are, the box body no consumption of print cartridge only consumes ink, and it is low to print cost; And help environmental protection.

Description of drawings

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

Fig. 1 is the cutaway view of toner cartridge main body, is the main part of Fig. 2 before assembling.

Fig. 2 is the cutaway view of print cartridge integral body.

Among Fig. 1 1. is ink storing chamber, 2. toner cartridge main body, 3. filter screen stand, 4. ink outlet port, the 5. black chamber of the notched storage in bottom dividing plate, the 6. breach of the black chamber of storage the lower partition, the 7. black chamber of storage.

Among Fig. 2 1. is sponge ink storing chamber that cavernous body is put into the 1. back formation of Fig. 1,2. toner cartridge main body, screen pack 3. seal weldings on filter screen stand 4., 5. are with the ink outlet port of rubber seal, 6. the black chamber of the notched storage in bottom dividing plate, 7. store the breach of black chamber the lower partition, 8. store black chamber, 9. air-vent, 10. print cartridge loam cake, 11. ink filling port, 12. ink filling port rubber stoppers.

The specific embodiment

Among Fig. 2 above the ink outlet port 5 of band rubber seal be screen pack 3 seal weldings on filter screen stand 4, the top print cartridge loam cake 10 of sponge ink storing chamber 1 places and carries out seal welding above the toner cartridge main body 2; Store black chamber dividing plate 6 part of print cartridge is separated into the black chamber 8 of storage, and the bottom of storing black chamber dividing plate 6 has breach 7, the bottom of sponge ink storing chamber 1 is communicated with the bottom of storing black chamber 8.Sealing ink outlet port 5 and air-vent 9 vacuumize from ink filling port 11 and to add Mo Houzai first and build ink filling port rubber stopper 12 and just can equally with common print cartridge use.Pack into the Mo Chehou of printer of print cartridge makes air-vent 9 unimpeded and keep being always normal pressure in the black chamber of storage.The ink outlet port 5 of the breach 7 of the black chamber 8 of storage, storage black chamber the lower partition, air-vent 9, sponge ink storing chamber 1, screen pack 3, band rubber seal and the ink entrance on the inkjet printer head have just formed a complete ink feeding system to the inkjet printer head ink supply like this.Adding ink needn't vacuumize.Opening the ink filling port rubber stopper 12 direct inks that add gets final product.
