Abstract

The utility model relates to field of printing consuming materials, in particular to a print cartridge for an ink-jet printer. The print cartridge comprises a print cartridge main body which comprises an upper cover and a bottom shell. A luminous chip is arranged on the bottom shell, light emitted by the chip is conducted to a light transferring pole outside the print cartridge main body, and the light transferring pole is arranged above the chip, wherein the light transferring pole is separated from the print cartridge main body, and the light transferring pole can be embedded inside the print cartridge main body. The print cartridge of the utility model improves the light transferring pole structure inside the print cartridge, the light transferring pole is separated from the print cartridge main body, the light transferring pole can be arranged in grooves on the upper cover and the bottom shell, and the light transferring pole and the upper cover are closely engaged to realize fixing. The design is not limited by print cartridge materials and colors, with low manufacturing cost and simple technique, which does not influence light transferring of the print cartridge.

Description

Ink box

Technical Field

The utility model belongs to the technical field of the printing consumables and specifically relates to an ink horn that uses in ink jet printer.

Background

The existing part of the ink box adopts a light guide structure design on the box body, the function of the existing part of the ink box is to guide a chip light source of the ink box to the outer surface, then the light signal is transmitted to a light signal receiving device in the printer, and the printer can normally work and print when detecting the light signal sent by the chip light source. However, such special requirements limit the design conditions of the ink cartridge, and in order to realize the above functions, the existing ink cartridge is designed to realize the light guide effect by using the transparent bottom case and the surface cover, so that the design appearance is single in color, and the cost of the used materials is higher; in addition, the color of the light guide column and the color of the ink box are separated by a double-color mold, and the color of the light guide column is made transparent. Although different materials can be used in the design, the material cost is saved, but the die cost is high and the process is complex.

Disclosure of Invention

The utility model aims at providing an ink box with low cost and simple process.

In order to achieve the above object, the utility model provides a following technical scheme: an ink cartridge includes

An ink cartridge main body including an upper cover and a bottom case;

a chip capable of emitting light, the chip being mounted on the bottom case;

guiding light emitted by a chip to a light guide column outside the ink box main body, wherein the light guide column is positioned above the chip;

wherein,

the light guide column is embedded in the ink box main body.

Grooves for accommodating the light guide columns are formed in the upper cover and the bottom shell.

The groove of the upper cover is tightly matched with the light guide column.

The utility model discloses leaded light post structure to in the ink horn improves, with leaded light post and ink horn main part separation design, the leaded light post can set up in the recess of upper cover and drain pan, realizes fixedly through closely cooperating between leaded light post and the upper cover. The design has no limit on the material selection and color of the ink box, the manufacturing cost is low, the process is simple, and the light guide of the ink box is not influenced.

FIG. 2 is a sectional view taken along line A-A of FIG. 1;

FIG. 3 is a view of the ink cartridge of FIG. 2 prior to being loaded into the light guide;

FIG. 4 is an enlarged perspective view of the light guide post of the ink cartridge of the present invention;

the present invention will be further explained with reference to the drawings and examples.

Detailed Description

Referring to fig. 1, 2 and 3, fig. 1 is a top view of the ink cartridge of the present invention, and fig. 2 and 3 respectively show longitudinal sectional views of the ink cartridge of the present invention before and after the ink cartridge is installed in the light guide. The ink box comprises an ink box main body, a light guide column 3 and a chip (not shown); the cartridge main body includes an upper cover 1 and a bottom case 2. The lower part of the bottom shell 2 is provided with a chute 4 for accommodating chips, the bottom shell 2 is also provided with a groove 21 which is arranged above the chute 4 and communicated with the chute 4, and the upper cover 1 is provided with a groove 11 which vertically corresponds to the groove 21. In leaded light post 3 inserted recess 11 and recess 21, closely cooperate between leaded light post 3 and the recess 11, the assembly is accomplished the back, and leaded light post 3 bottom just in time aims at the luminous position of chip (as shown in figure 2). Referring to fig. 4, the light guide pillar 3 has a T-shaped longitudinal section (as shown in fig. 2 and 3), the lower portion of the light guide pillar 3 near the chip is an inclined plane 31, and the inclined plane 31 is substantially parallel to the placement angle of the chip, so that the light emitted from the chip can be guided upward more effectively; the top of the light guide column 3 is provided with a light guide inclined plane 32, and the light guide inclined plane 32 faces to the optical signal receiving device in the printer, so that the light transmitted from the bottom of the light guide column 3 can be refracted by the light guide inclined plane 32 and then emitted to the optical signal receiving device in the printer; in addition, a protruding block 33 is further disposed on the top of the light guide column 3, and when the light guide column 3 is assembled into the ink cartridge main body, the protruding block 33 is embedded into the upper cover 1, so that the light guide column 3 can be transversely positioned.

The above structure is only a preferred embodiment of the ink cartridge of the present invention, and the specific structure thereof can also be deformed as follows:

first, the bottom slope and the top slope of the light guide column are not necessary, and the light signal can be transmitted to the light signal receiving device of the printer without the slope.

Further, the mechanism of the light guide bar is not limited to the structure in the above embodiment, and it is obvious that the light emitted from the bottom cartridge chip can be guided out of the outer surface of the cartridge, and it may be cylindrical or other irregular shapes as long as it is made of a light-transmitting material.

Finally, in the above embodiment, the light guide pillar is closely matched with the groove of the upper cover to realize positioning. The light guide column can also be positioned by adopting a mode such as embedding, hooking, sticking and the like.

Of course, the structure of the ink cartridge of the present invention is not limited to the above-mentioned embodiments and the modifications listed below, and variations such as integrally forming the top cover and the bottom case are also obvious. Variations that do not depart from the gist of the invention are intended to be within the scope of the claims.
