In the conventional ink cartridge, a chip is usually disposed at the front end of the ink cartridge, and the chip stores information related to the ink cartridge, such as the production date, the color of ink, and the remaining amount of ink in the ink cartridge. Accordingly, the printer is provided with electrical connections in conductive contact with the chip so that the printer can read information such as the amount of ink remaining in the chip. The chip can be dismantled with the casing of ink horn and be connected, when the ink horn needs to be upgraded, can directly change the chip of ink horn. However, replacing the chip of the cartridge requires removal of the cartridge packaging, which can be costly to upgrade.

Through repeated thinking and verification, the inventor finds that if the upgrading probe can be used for directly penetrating from the outside of the packaging bag and electrically contacting with the electric contact of the chip, the contact pin of the upgrading probe is used for directly rewriting data in the chip, so that the packaging bag does not need to be removed in the upgrading process of the ink box, and the upgrading cost of the ink box is reduced.

In view of the above, the inventors have devised an ink cartridge including a housing, first and second walls extending in a vertical direction, and a chip. The first wall and the second wall are located at the top of the front end of the shell, the first wall is opposite to the second wall, and the first wall and the second wall are arranged at intervals along the first horizontal direction. The chip is arranged on the surface of the first wall facing the second wall and fixedly connected with the first wall, and a plurality of electric contacts are arranged on the surface of the chip facing the second wall. The second wall is provided with a plurality of avoidance parts, the avoidance parts correspond to at least one part of the electric contacts of the chip one by one, and contact pins of the upgrading probe penetrate through the avoidance parts to communicate with the electric contacts of the chip. When the ink box is upgraded, the contact pin of the upgrading probe can be pierced from the outside of the packaging bag and passes through the avoiding part of the second wall to communicate with the electric contact of the chip, so that the chip is rewritten, and the upgrading cost of the ink box is reduced.

The front side wall of the ink cartridge is further provided with an air-inflating opening 150. illustratively, the air-inflating opening 150 is located above the ink outlet 140. The inside of the ink cartridge is provided with an air bag communicating with the pump port 150. It should be mentioned that the inflating opening 150 is used to connect with an air pump of the printer, when the ink in the ink chamber of the printer is less, the air pump of the printer inflates the inflating opening 150, so that the air bag expands to squeeze the ink in the ink chamber into the printer.

The X-axis direction in FIG. 1 is defined as the first horizontal direction, and the X-axis positive direction is the right side of the ink box; in fig. 1, the Y-axis direction is the second horizontal direction perpendicular to the first horizontal direction, and the positive Y-axis direction is the front side of the ink cartridge.

The chip 400 is mounted on the surface of the first wall 200 facing the second wall 300, illustratively, the first wall 200 is located on the left side of the second wall 300, and the chip 400 is mounted on the right side of the first wall 200. It will be understood by those skilled in the art that the placement of the chip 400 on the surface of the first wall 200 facing the second wall 300 prevents the chip 400 from being damaged during transportation of the cartridge, and that the space between the first wall 200 and the second wall 300 may be used to accommodate electrical connectors of the printer that make electrical connection with the chip 400 when inserted between the first wall 200 and the second wall 300.

Illustratively, the chip 400 may be attached to the first wall 200 by means of fastener fastening, adhesive bonding or snap-fit attachment. For example, as shown in fig. 2, the surface of the first wall 200 facing the second wall 300 is provided with a mounting groove 210, and exemplarily, the mounting groove 210 may extend in a front-rear direction and both front and right sides of the mounting groove 210 are provided with openings, so that the chip 400 may be inserted into the mounting groove 210 from the opening of the front side of the mounting groove 210 and interference-connected with the mounting groove 210 at the time of assembly, that is, the chip 400 is embedded in the mounting groove 210. And the electrical connections of the printer can be in conductive contact with the chip 400 from the opening on the right side of the mounting slot 210. Preferably, the mounting groove 210 and the first wall 200 may be formed as a single piece through a one-time molding process.

Those skilled in the art can understand that the mounting groove 210 is disposed on the surface of the first wall 200 facing the second wall 300, and the chip 400 is fixed by the mounting groove 210, so that the stability of connection between the first wall 200 and the chip 400 can be ensured, and further the chip 400 is not easy to fall off in the mounting and dismounting processes of the ink cartridge, and meanwhile, the chip 400 and the first wall 200 can be detachably connected, and the chip 400 of the ink cartridge can be replaced when needed.

With continued reference to fig. 1, the surface of the chip 400 facing the second wall 300 is provided with a plurality of electrical contacts 410, and it is easy to understand that the electrical contacts 410 are interfaces in the chip 400 for connecting with external circuits, and the present embodiment is not limited to the specific form of the electrical contacts 410 of the chip 400, and for example, the electrical contacts 410 of the chip 400 may be an I2C (Inter-Integrated Circuit bus) data interface, and when the electrical contacts 410 are I2C, the I2C communication protocol of the chip may be modified after the contact pins of the upgrade probe are in conductive contact with the electrical contacts 410.

The second wall 300 is provided with a plurality of reliefs, which correspond to at least a part of the electrical contacts 410 of the chip 400 one to one, for example, the first wall 200 is located at the left side of the second wall 300, the chip 400 is mounted at the right side of the first wall 200, that is, the second wall 300 is located at the right side of the chip 400, and the electrical contacts 410 of the chip 400 face the right side of the chip 400. The relief in the second wall 300 is to the right of the electrical contact 410 of the chip 400 so that the stylus of an upgraded probe can pass right to left through the relief of the second wall 300 and make conductive contact with the electrical contact 410 of the chip 400. It will be readily appreciated that the relief may expose the electrical contacts 410 of the chip 400 corresponding to the relief, wherein the relief may be any suitable shape, such as circular or square. It will be readily appreciated that the cross-sectional area of the bypass is not less than the cross-sectional area of the stylus to ensure that the stylus of an upgraded probe can pass through the bypass on the second wall 300.

Those skilled in the art can understand that the avoiding portion on the second wall 300 can also play a role in positioning, that is, when the ink cartridge needs to be upgraded, a worker can directly determine the specific position of the electrical contact 410 on the chip 400, and then can directly insert the contact pin of the upgrade probe from the avoiding portion on the second wall 300 to be in conductive contact with the electrical contact 410 of the chip 400 to realize communication between the contact pin and the electrical contact 410, the ink cartridge does not need to remove the packaging bag outside the ink cartridge in the upgrading process, the contact pin of the upgrade probe is directly pierced from the outside of the packaging bag, the efficiency of upgrading the ink cartridge is improved, and the cost of upgrading the ink cartridge is reduced.

It is easily understood that the number of the electrical contacts 410 on the chip 400 is not limited, and may be three or more, and those skilled in the art can set the specific number of the electrical contacts 410 on the chip 400 according to the kind of the chip 400 and the ink cartridge. At least one electrical contact 410 of the chip 400 is located on the front side of the chip 400, and illustratively, as shown in fig. 1, the front side of the chip 400 is provided with a gold finger contact group, i.e., the electrical contact 410 on the front side of the chip 400, through which the chip 400 can be in conductive contact with an electrical connector of a printer.

As shown in fig. 1-2, the avoidance portion includes a plurality of avoidance holes 310 and an avoidance groove 320 at a front end of the second wall 300, and both left and right sides of the avoidance groove 320 are open, and the avoidance groove 320 is exemplarily approximately rectangular in shape. The avoiding groove 320 is opposite to the contact position of the front side of the chip 400, that is, when the ink cartridge is upgraded, the upgrading probe can penetrate from right to left through the avoiding groove 320 to be in conductive contact with the contact group of the front side of the chip 400. The cross-sectional size of the avoiding groove 320 is not limited in this embodiment, and those skilled in the art can set the cross-sectional size according to actual needs.

It can be understood by those skilled in the art that the avoiding portion includes a plurality of avoiding holes 310 and an avoiding groove 320 at the front end of the second wall 300, and the avoiding groove 320 is opposite to the electric contact 410 at the front side of the chip 400, so that all the electric contacts 410 on the chip 400 are exposed in the direction toward the second wall 300, thereby facilitating the worker to use the contact pin of the upgrade probe to contact with the electric contact 410 of the chip 400, and then rewrite the chip 400.

In the ink cartridge provided in the present embodiment, the first wall 200 and the second wall 300 are detachably connected to the casing 100 of the ink cartridge, specifically, as shown in fig. 2 to 6, the ink cartridge further includes a mounting portion 500, and for example, the mounting portion 500 may have a box-like structure. The top of the front end of the housing 100 is provided with an inwardly recessed recess 130, and the recess 130 is, for example, a notch at the top of the front end of the housing 100, and a person skilled in the art can set the size of the notch at the top of the front end of the housing 100 according to actual needs, and the embodiment is not limited herein. The mounting part 500 is disposed in the recess 130 and the mounting part 500 is detachably coupled to the recess 130, and illustratively, the mounting part 500 may be coupled to the recess 130 of the housing 100 by means of bolt fastening or snap coupling.

Fig. 2 to 6 show that the front side of the mounting part 500 is provided with an opening, and a receiving cavity for receiving the electrical connector is provided inside the mounting part 500, i.e. the opening of the receiving cavity is located at the front side of the receiving cavity. The first wall 200 and the second wall 300 are respectively opposite side walls of the mounting portion 500, for example, the first wall 200 is a left side wall of the accommodating cavity, and the second wall 300 is a right side wall of the accommodating cavity. Preferably, the mounting part 500 may be formed as an integral part through a one-time molding process, thereby reducing a process of assembling the mounting part 500 at a later stage and improving production efficiency of the ink cartridge. It will be readily appreciated that providing first wall 200 and second wall 300 as opposing sidewalls of mounting portion 500, with mounting portion 500 securing chip 400, and detachable attachment of mounting portion 500 to housing 100 may improve the versatility of housing 100, i.e., housing 100 of an ink cartridge may be provided with different mounting portions 500 and thus different chips 400.

In one possible implementation, the bottom of the mounting part 500 is provided with a positioning protrusion 520 extending downward and a claw 510 extending downward, and correspondingly, the top of the recess 130 is provided with a catching groove 131 extending downward and a slot 132 extending downward. It will be readily appreciated that during assembly of the mounting portion 500, the detents 510 at the bottom of the mounting portion 500 snap into the detents 131 at the top of the recess 130 and the locating projections 520 at the bottom of the mounting portion 500 are inserted into the slots 132 at the top of the recess 130. Illustratively, the positioning protrusion 520 may be a plate-like structure perpendicular to the Y-axis.

It will be readily appreciated that the side walls of the jaws 510 are provided with projections, illustratively at the bottom end of the jaws 510 and towards the rear side of the jaws 510. The shape of the protrusion can be set by those skilled in the art according to actual needs, for example, the cross-sectional shape of the protrusion can be triangular or semicircular. Correspondingly, the side wall of the card slot 131 is a stepped surface, and exemplarily, the side wall of the card slot 131 is provided with a stopper protruding towards the inside of the card slot 131, and the stopper makes the side wall of the card slot 131 form a stepped surface. It will be readily appreciated that the stepped surface of the pocket 131 is adapted to abut the protrusion of the pawl 510, and in particular, the top of the protrusion abuts the bottom surface of the stepped surface.

It can be understood by those skilled in the art that the positioning protrusion 520 is disposed at the bottom of the mounting part 500, the slot 132 is disposed at the top of the recess 130, and the positioning protrusion 520 is inserted into the slot 132, so that the degree of freedom of the mounting part 500 in the horizontal plane is limited; meanwhile, the jaws 510 and the catching grooves 131 may define a degree of freedom of the mounting part 500 in a vertical direction. So that the mounting part 500 and the housing 100 can be stably coupled.

It is easily understood that the number of the jaws 510 and the positioning protrusions 520 is not limited, and may be one or more, for example, as shown in fig. 3, the bottom of the mounting portion 500 is provided with one jaw 510 and two positioning protrusions 520, the two positioning protrusions 520 are spaced apart in the second horizontal direction, the centers of the jaws 510 and the centers of the two positioning protrusions 520 are located on the same straight line, and the jaws 510 and the positioning protrusions 520 are also spaced apart. It should be noted that the second horizontal direction is the mounting and dismounting direction of the ink cartridge, and the direction indicated by the arrow in fig. 3 is the mounting direction of the ink cartridge. The distance between adjacent positioning protrusions 520 is not limited in this embodiment, and those skilled in the art can set the distance according to actual needs.

It will be appreciated by those skilled in the art that the plurality of positioning protrusions 520 are spaced apart along the second horizontal direction, further limiting the degree of freedom of the mounting portion 500 along the second horizontal direction, i.e., the mounting portion 500 will not fall out of the recess 130 of the housing 100 during mounting and dismounting of the ink cartridge.

Further, as shown in fig. 4, the outer side wall of the mounting portion 500 is provided with an anti-slip layer 530, for example, the anti-slip layer 530 may be a stripe provided on the outer side wall of the mounting portion 500, wherein the stripe may extend along the Y-axis direction in fig. 4, or the stripe may also be a wavy structure. The middle of the stripe may be provided with an arrow pointing upward of the ink cartridge, and it is easily understood that the arrow may serve as an indicator for removing the mounting portion 500. In one possible implementation, the mounting part 500 may form the anti-slip layer 530 on the outer sidewall through a one-time molding process.

As will be appreciated by those skilled in the art, the anti-slip layer 530 is disposed on the outer sidewall of the mounting portion 500, so that the friction between the mounting portion 500 and the fingers can be increased during the process of removing the mounting portion 500 from the housing 100, thereby facilitating the removal of the mounting portion 500 by the worker.
