Abstract

The utility model discloses an ink box capable of changing an ink discharging core, which has the advantage of simple structure; a small sponge at an ink outlet can be replaced, the capacity of ink is large and ink can be repeatedly filled. The utility model comprises an ink box body, an ink box cover which covers the ink box body and an ink balancing device. The utility model is characterized in that outside the bottom of the ink box body, a pit which is concave towards the inner part of the ink box body is arranged at the position of the ink outlet; a hole or a groove which is communicated with the inner part of the ink box body is arranged on the pit, and a porous elastomer is placed in the pit. The utility model can be applied to an ink box used on an ink jet printer and an external ink supply type ink box which is matched with an ink jet printer.

Description

The replaceable print cartridge that goes out Mo Xin

Affiliated technical field

The utility model relates to a kind of equipment of ink-jet printer, more particularly, relate to the print cartridge that uses on the ink-jet printer and with the print cartridge of the outer ink supply of the supporting use of ink-jet printer.

Background technology

The print cartridge that sponge is arranged usually is the sponge that bulk is housed in cartridge body, bottom in cartridge body is shaped on pit, the bottom of pit has and the extraneous hole that communicates, be placed with the fritter sponge in the pit for going out Mo Xin, form ink outlet port, little sponge closely contacts with big sponge, when filling in the cartridge body has ink, is attracted in the big sponge.When printing, the blotting mouth of printer inserts from the hole of pit, contacts with little sponge, under the effect of negative pressure, with the ink sucking-off in the big sponge, realizes inkjet printing.But the print cartridge of this structure is because the interior big sponge of cartridge body occupies certain space, and therefore, ink capacity is little, can not repeat to add ink injection, and little sponge can produce plastic deformation under the long-term roof pressure of blotting mouth, and little sponge can not closely closely be contacted with blotting mouth or big sponge, cause blotting discontinuous, even want to change little sponge,, change because it is to put in cartridge body, must open ink box cover, it is just passable to take out big sponge.But this way is reality not quite.Therefore the print cartridge of this structure is short service life, can not reuse.

The utility model content

The utility model provides a kind of simple in structure, and the little sponge of ink outlet port can be changed, and ink capacity is big, can add the print cartridge of the replaceable Mo Xin of going out of ink injection repeatedly.

In order to achieve the above object, the utility model is achieved through the following technical solutions: comprise cartridge body, cover ink box cover, the ink bascule of cartridge body, it is characterized in that outside in the cartridge body bottom, be shaped on pit recessed in cartridge body in the position of ink outlet port, be shaped on the pit with cartridge body in the hole or the groove that communicate, be placed with porous elastomers in the pit.

The replaceable print cartridge that goes out Mo Xin according to the such scheme manufacturing, in use when the interior porous elastomers of pit, because long-term compression produces plastic deformation, can change in the cartridge body outside easily, and saved the interior big sponge of cartridge body, increase ink capacity, and can repeat to add ink injection, print cartridge can use repeatedly, not only economy but also environmental protection.

Description of drawings

Fig. 1 is a print cartridge structural representation of not putting porous elastomers in the pit;

Fig. 2 is the print cartridge structural representation that is placed with porous elastomers in the pit;

Fig. 3 is the print cartridge structural representation that is placed with porous elastomers and pipe in the pit.

Wherein: 1, cartridge body; 2, ink box cover; 3, ink bascule; 4, pit; 5, hole; 6, porous elastomers; 7, pipe.

The specific embodiment

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

Fig. 1 is a print cartridge structural representation of not putting porous elastomers in the pit.Comprise cartridge body 1, cover ink box cover 2, the ink bascule 3 of cartridge body 1, the outside in cartridge body 1 bottom is shaped on pit recessed in cartridge body 14 in the position of ink outlet port, be shaped on the pit 4 with cartridge body in the hole 5 that communicates.

Fig. 2 is the print cartridge structural representation that is placed with porous elastomers in the pit.It is to be placed with porous elastomers 6 in pit 4, and porous elastomers 6 can be that sponge also can be the kapok core.

Fig. 3 is the print cartridge structural representation that is placed with porous elastomers and pipe in the pit.It is that flexible pipe 7 is installed around the pit inwall, is placed with porous elastomers 6 in the middle of the pipe 7.This structure can make the blotting mouth of printer closely contact with pipe 7, prevents that air from sucking.

Above structure can be on printer monochromatic print cartridge or polychrome print cartridge use, also can be used on the print cartridge with the supporting outer ink supply of ink-jet printer and use.

Claims

1, the replaceable print cartridge that goes out Mo Xin, comprise cartridge body, cover ink box cover, the ink bascule of cartridge body, it is characterized in that outside in the cartridge body bottom, be shaped on pit recessed in cartridge body in the position of ink outlet port, be shaped on the pit with cartridge body in the hole or the groove that communicate, be placed with porous elastomers in the pit.

2, the replaceable print cartridge that goes out Mo Xin according to claim 1, it is characterized in that the pit inwall around flexible pipe is installed, be placed with porous elastomers in the middle of the pipe.
