Description

The print cartridge of band ink duct

Affiliated technical field

The utility model relates to a kind of inkjet printing machine equipment, more particularly, relates to a kind of ink-jet printer cartridge.

Background technology

Print cartridge normally is made up of the ink box cover of cartridge body and sealing cartridge body, is perfused with ink in the cavity of cartridge body and ink box cover.Along with the minimizing of ink, the outer air of box enters in the box at any time when printing, the ink that compensation consumes, and the pressure equilibrium with inside and outside the maintenance print cartridge makes inkjet printing normal.In addition, because the increase of temperature or the effect that print cartridge is subjected to external force also can make the interior pressure of print cartridge greater than outside the print cartridge, cause air or ink in the print cartridge outside box, to overflow.For this reason, generally on ink box cover, done the snakelike slot type passage in labyrinth, the print cartridge inner air and outer air is communicated.Because the structural limitations of ink box cover, the capacity of the snakelike slot type passage in labyrinth is very limited, and ink still overflows from passage sometimes, in addition, the injection-molded structure complexity of the snakelike slot type passage in labyrinth, the processing cost height, production efficiency is low.

The utility model content

The purpose of this utility model aims to provide a kind of simple in structure, good manufacturability, the anti-excessive print cartridge of ink.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions: the print cartridge of band ink duct, it has at least one chamber to comprise a cartridge body, be provided with the ink outlet port that communicates with described chamber in the bottom of cartridge body, the top of cartridge body is the opening of chamber, in chamber, irritate ink is arranged, this print cartridge also comprises an ink box cover that covers described chamber opening, has a pouring ink hole on the ink box cover at least, an air admission hole, the upper surface of ink box cover is shaped on the groove that links to each other with air admission hole, bonding with film at the ink box cover upper surface that air admission hole links to each other with groove, the upper surface of ink box cover is shaped on the black pit of storage, and air admission hole just is located at the black pit bottom of storage.

According to the print cartridge that such scheme is made, the beneficial effects of the utility model are: can simplify the injection-molded structure of ink box cover, reduce die cost; When the pressure in the print cartridge greater than print cartridge outside the time because the effect of the black pit of storage, the ink that overflows from air admission hole can be stored in the black pit and can not flow to outside the print cartridge, and can flow back in the print cartridge again.

The specific embodiment

The utility model will be further described below in conjunction with accompanying drawing.

Fig. 1 to Fig. 9 is the print cartridge structural representation of 5 kinds of color belt ink ducts.Cartridge body 1 is separated into 5 chambers 3 by dividing plate 2, it is chamber 3 of a kind of color, in each chamber 3 print cartridge pressure equaliser 4 is installed, an ink box cover 5 that covers chamber 3 openings is arranged, a pouring ink hole 6, an air admission hole 7 are arranged on the ink box cover 5 of corresponding each chamber 3.The upper surface of ink box cover 5 is shaped on the black pit 8 of storage, and described air admission hole 7 just is located at the bottom of the black pit 8 of storage.Air admission hole 7 lower ends are pipes 9, and the head of pipe 9 is equipped with check valve 10, and pipe 9 reaches the bottom of cartridge body 1 always.

Storing up the air slot 11 of black pit 8 by ink box cover 5 upper surfaces communicates respectively with to discharge orifice 12, at the black pit 8 of storage, bonding with film 13 to the surface of discharge orifice 12 and

air slot

11,5 to discharge orifice 12 concentrated being arranged in a row, also have 5 passages 14 on the parallel therewith ink box cover 5, to discharge orifice 12 and passage 14 chute 15 is communicated with them by ink box cover 3 lower surfaces respectively, to discharge orifice 12, passage 14, ink box cover 5 lower surfaces of chute 15 are posted diaphragm seal 16, form the U-shaped passage.Be Welding Structure between described cartridge body 1 and the ink box cover 5.5 to discharge orifice 12 and 5 passages 14 concentrated being arranged on the ink box cover 5 at same chamber 3 tops.

The schematic diagram of Fig. 8 after to be ink box cover 5 upper surfaces with film 13 bonding.Film 13 does not hide 5 passages 14 at storage black pit 8, bonding to the upper surface of discharge orifice 12 and air slot 11 after bonding, and 5 chambers all have the relatively independent passage that communicates respectively with passage 14 after film 13 is bonding.

It is bonding with film 13 that Fig. 9 is ink box cover 5 upper surfaces, and 14 mouthfuls of passages are with the structural representation after adhesive tape 17 sealings.After adding ink injection in the print cartridge, an end of rectangle band viscosity adhesive tape 17 prevents that with 14 sealings of 5 passages ink from overflowing, and all the other exposed parts are for conveniently throwing off adhesive tape 17 in use, to keep the ink supply smoothness.

More than be the embodiment of 5 kinds of color ink-jet printer cartridges,, can manufacture the print cartridge of the serial ink-jet printer of a plurality of chambers such as a chamber, two chambers, three chambers, four chambers according to the utility model.
