Description

Ink-jet printer cartridge

Technical field

The utility model relates to the black liquid supplying device that a class ink-jet printer is used, the print cartridge that particularly has the soft bag of black liquid and can be carried out the air pressure adjustment ink supply by printer.

Background technology

Usually, ink jet printing device all has a printhead.Be the black liquid that storage print is used, ink jet printing device all has a removably print cartridge at least, and it supplies black liquid to printhead constantly in print procedure.

Application number is that 01100560.2 Chinese invention patent ublic specification of application discloses the innovation and creation of " print cartridge and the ink-jet printer that adopts this print cartridge " by name, its disclosed print cartridge structural principle is referring to Fig. 1, constitute by the China ink bag 4 of having loaded onto printing ink and the air-tight case body 5 that it is contained in inside, cavity 3 adds air pressure by air inlet pipe 1 between box body 5 and China ink bag 4, thereby supply with the print cartridge of printing ink by ink supply pipe 2 to printhead, box body is made of the conjugant of lower box body and upper cartridge body, China ink bag 4 is put into behind the lower box body upper cartridge body from the upper cap, by vibrating deposited or hot melt applies both are engaged airtightly.The assembling of this print cartridge with take apart very not very conveniently because airtight requirement is arranged, the structural design of box body and processing, assembling all have higher requirement.

Application number is that the Chinese invention patent ublic specification of application of 00135955.X discloses the innovation and creation of " ink cartridge " by name, its disclosed print cartridge structural principle is referring to Fig. 2, its box body 12 also is one and has China ink pipe 11, the box that seal request is arranged, box body 12 is built-in with an airbag 7, air inlet pipe 6 is passed and is fixed on the box body 12, in the black chamber 10 of China ink liquid level in box body 12 and between the airbag 7, China ink also is equipped with a spring 8 and a pressing plate 9 in the chamber 10, spring 8 and airbag 7 lay respectively at the both sides of pressing plate 9, be that spring 8 is fixed between 12 1 madial walls of box body and the pressing plate 9, airbag 7 clamps are between another madial wall of pressing plate 9 and box body.When airbag 7 owing to the ink in the black chamber 10 flows out the fluid pressure that makes this China ink chamber 10 in and reduces when expanding by going out China ink pipe 11, spring 8 passes through pressing plate 9 oppressive airbags 7, makes it can excessive expansion, thereby makes the suitable negative pressure of black chamber 10 inner sustain.

Summary of the invention

From in essence, the structural principle of above-mentioned two kinds of print cartridges is basic identical, all be dividing coelosis and two airtight parts of bag in the box body, only a kind of is with the black liquid of bag storage, another kind is to receive with bag to mend the gas of going into, they have any is common, is exactly all to require a box body that satisfies the close condition of gas (liquid).Obviously, make a box body that satisfies airtight or the close requirement of liquid and make non-airtight or box body that liquid is close relatively, higher processing and manufacturing requirement is arranged, thereby higher manufacturing cost is arranged.

Main purpose of the present utility model provides a kind of close print cartridge that requires box body of no gas (liquid) that has, and reduces manufacture process requirement, thereby finally reduces use cost.

Another purpose of the present utility model provides a kind of print cartridge with no requirement of withstand voltage box body, thereby further reduces use cost.

For achieving the above object, the technical scheme of employing is the box body with a shell shape, is built-in with flexible China ink bag at box body, going out on the sidewall that black pipe passed and be fixed on print cartridge of China ink bag, like this, satisfying under the condition of certain pressure, the black liquid in the bag will be through going out black pipe to the printhead ink supply.For satisfying the pressure condition of above-mentioned ink supply, in box body, also be equipped with flexible airbag, the air inlet pipe of airbag passes and is fixed on the sidewall of print cartridge.After the air pump of air inlet pipe and printer was connected, printer can be regulated supply gas pressure automatically, makes airbag extruded ink bag in box body, thereby discharges black liquid.

By above scheme as seen, the utility model has increased an airbag than prior art, thereby makes box body break away from the requirement of close property.

Such scheme makes box body need not the requirement of close property, but in the process of airbag extruded ink bag venting, inboard wall of cartridge still is subjected to airbag pressure, for reducing even eliminating this pressure, airbag and China ink bag can be combined as a whole, both in shared one every face, in have and two essentially identical surface areas of side pocket face that constitute airbag and China ink bag and curve form every face.Airbag has essentially identical maximum volume with the China ink bag.Because two side pocket faces are inelastic flexible materials, and identical profile is arranged when being full of black liquid or gassy, and, after forming this profile, can not increase deformation takes place with the continuation of pressure.Therefore, as long as the maximum profile of gas, black complex pocket is made identical with the spatial form of bag container in the box body, gas, black complex pocket just can not produce pressure to inboard wall of cartridge.

Below in conjunction with embodiment the utility model and accompanying drawing thereof are described further.

Embodiment

First embodiment:

Referring to Fig. 3, Fig. 4, box body 15 inner chambers are equipped with an airbag 14 and a China ink bag 16, because gas-liquid is all in bag, so box body 15 need not the requirement of close property, that is to say between the upper and lower box body and need not adopt ultra-sonic welded, can be designed to the buckle ways of connecting and assemble very easily.The ink supply pipe 17 of the air inlet pipe 13 of airbag 14 and China ink bag 16 all is fixed on the sidewall of box body 15.What Fig. 3 described is a new print cartridge that is full of black liquid, its China ink bag 16 is full, airbag is empty, when the printer of packing into carries out work, constantly inflation in airbag 14 of air pump, ensure the black toward print head in the China ink bag 16, this is that China ink bag 16 volumes reduce the process that airbag 14 volumes enlarge gradually gradually.When the China ink in the China ink bag 16 exhaust or the time, airbag 14 has maximum volume as shown in Figure 4.

Second embodiment

Referring to Fig. 5, Fig. 6 and Fig. 7, these routine characteristics are that China ink bag 16 and airbag 14 are made a bag that is made of

lateral surface

18 and 20, have in the bag in a slice every face 19, in have the curved surface identical and surface area and bag inside be separated into airbag 14 and China ink bag 16 every face 19 with lateral surface 18,20.

Lateral surface

18,20 and in can omit the flexible material of disregarding every face 19 by elasticity and make, just black liquid and pumping under the maximum pressure value of gas, their percentage elongation in the curved surface that is shaped separately are zero, therefore, no matter are to be full of under the situation of black liquid, still in the process of inflation venting, the maximum volume of bag can not change, and like this, bag just can not produce pressure to the inwall of box body, in other words, manufacturing and designing of box body need not to consider close property and requirement of withstand voltage.

This routine operation principle is as follows, and print cartridge such as Fig. 5 after the new or renewing be full of black liquid in its China ink bag 16, and airbag 14 are in the minimum volume state.Referring to Fig. 6, be accompanied by the carrying out of print job after the installation, be the consumption of black liquid on the one hand, be gas replenishing in airbag on the other hand, during this makes every face 19 from the outside side of the state that is adjacent to lateral surface 18 20 1 side shiftings.Referring to Fig. 7, when black liquid exhausted, airbag 14 reached its maximum volume, and China ink bag 16 reaches the minimum volume state, in be close to lateral surface 20 every face 19.
