Description

An ink cartridge for an inkjet printer

Technical field

The utility model relates to an ink cartridge for an inkjet printer. Background technique

An ink cartridge for an inkjet printer commonly used in the society, an integrated circuit chip is disposed on the side of the ink cartridge for receiving a printer signal, and the ink of the ink storage portion of the ink cartridge is driven by the corresponding ink flow channel and the ejection record under the driving of the printer signal. The device ejects ink onto a recording medium such as paper, and feeds back information about the ink cartridge, such as ink type, color, and capacity, to the printer.

Therefore, the chip needs to be stably and accurately mounted on the ink cartridge. The conventional installation method is to provide a through hole and a concave portion on the chip respectively to match the two circular positioning posts on the side wall of the ink cartridge (shown in FIG. 1). The chip is then attached to the chip mounting portion by gluing or heat soldering. However, the chip is fixed by a circular positioning post. During the installation process, it takes a long time to align, and both circular positioning posts need to be pasted or heat welded, which increases the production cost.

A solution, as mentioned in the patent CN200820043933, is that a cantilever rod is arranged as an elastic constraint portion above the chip mounting portion, and an opening tooth is provided as a constraint portion under the chip mounting portion, so that although the welding is omitted, When the chip is mounted to the chip mounting portion, a large force is required to expand the two constraining portions to the two sides, and the chip can be inserted into the groove, and the constraining portion is generally made of a material having elasticity, so that if it is used for the expansion constraint When the force of the part is too large, the restraint will be deformed and damaged, and the chip will be loosened after being mounted in the groove, so that the chip cannot accurately match the power contact in the printer. Utility model content

The utility model provides an ink cartridge for an inkjet printer. To solve the technical problems of inaccurate positioning, slow installation speed, and instability and durability after installation in the ink cartridge chip of the existing inkjet printer.

In order to solve the above technical problems, the technical solution adopted by the utility model is:

An ink cartridge for an inkjet printer, comprising an ink storage portion for storing ink; an ink supply portion for supplying ink in the ink storage portion to the printer; a chip for storing information related to the ink cartridge; a chip mounting portion on one side wall of the ink cartridge; the chip mounting portion includes a groove matching the chip, wherein the groove is provided with a card slot at one end and a positioning post at the other end; One end of the chip corresponding to the positioning post is provided with a recess matching the positioning post.

A step for supporting the chip is disposed in the groove.

The recess is provided as a semi-circular opening.

The chip can be inserted into the card slot obliquely at an angle to the side wall of the ink cartridge.

After the above technical solution is adopted, since one end of the groove is provided with a card slot, the other end is provided with a positioning post; and one end of the chip corresponding to the positioning post is provided with a concave portion matching the positioning post. When the chip is fixed on the ink cartridge, only one end of the chip is formed at an angle with the side wall of the ink cartridge, inserted into the card slot, and then rotated along the concave direction of the groove along the intersection of the chip and the card slot. The recess from the chip to the other end of the chip is closely matched with the positioning post, and finally the positioning post and the chip are fixed by bonding or soldering. In this way, the chip can be inserted into the chip mounting portion unconstrainedly and rotationally, which solves the technical problem that the ink cartridge chip of the existing ink jet printer is slow to be installed during installation and unstable after installation.

Through the above technical solution, the problem that the chip is difficult to locate during the installation process and the constraint portion is easily deformed is solved. Moreover, the installation method provided by the utility model makes the chip installation speed faster, and only needs to be welded once, which greatly improves the production efficiency. DRAWINGS

2, 3, 4, and 5, the ink cartridge for an inkjet printer of the present invention, as shown in FIG. 3, FIG. 4, and FIG. 5, the ink cartridge 1 includes an ink cartridge main body 2, and the main body is composed of an upper wall 9 and a lower wall 10. a first side wall 11, a second side wall 12, a front wall 13 and a rear wall 14 opposite to the front wall; an ink storage portion 3 for storing ink in the main body 2; and an ink supply portion 4 for supplying ink to the ink jet printer The chip 7 reflecting the information related to the ink cartridge 1 includes the ink type, the color of the ink cartridge, the ink capacity, and the like, and the chip 7 is provided with a recess 20 at one end thereof and a chip mounting portion located at the first side wall 11 of the ink cartridge.

The chip mounting portion includes a recess 5 on both sides of the recessed portion 18, 19, and the distance between the two limiting portions 18, 19 is equal to the width of the chip, which prevents the chip 7 from being perpendicular to the front wall There is a displacement in the direction of 13; a groove 6 is provided at one end of the groove 5, the card slot 6 is located in an arc portion 8, the chip 7 can be obliquely inserted into the card slot 6 at an angle; and the other end is provided with a chip Positioning post 17, the chip positioning post 17 is for mating with the semi-circular chip recess 20; and the recess 5 further includes a plurality of steps 22, 23, 24 which are spaced from the first side wall 11 of the ink cartridge 1 The distance is exactly equal to the back thickness of the chip 7, which ensures that the chip 7 and the power terminals in the printer stably cooperate with each other.

The process of fixing the chip 7 on the side wall 11 of the ink cartridge: First, the chip 7 is obliquely inserted into the card slot 6 at a convenient mounting angle (usually less than 90°), and then the end of one chip 7 and the card slot 6 are intersected. As a center of rotation, the other end of the rotating chip 7 is rotated in the concave direction 16 to the long semicircular recess 20, the recess 20 is mated with the chip positioning post 17, and then the chip is bonded or thermally welded. The positioning post 17 is fixed; thus, under the cooperation of the card slot 6, the chip positioning post 17, the limiting portions 18, 19, the steps 22, 23, 24, the chip 7 can be quickly and stably fixed to the chip of the ink cartridge side wall 11 On the installation section.

Of course, the ink cartridge may also be of a split type. As shown in FIG. 2, the chip mounting portion may be disposed on the adapter 15, so that the ink cartridge body 2 is only needed during use, and the chip 7 and the adapter 15 can be reused. The production cost of the ink cartridge 1 is further reduced; and the chip recess 20 can also be provided as a through hole, and the chip positioning post 17 mated with the chip recess is disposed in a cylinder that cooperates with the through hole.

It can be seen that the utility model can be inserted into the card slot 6 without restriction during the installation process of the chip 7, and only one chip positioning column 17 is used; it is difficult to locate the through hole and the groove (Fig. 1). The soldering is two times, so that the chip is fixed for a long time; and the technical solution can ensure that the chip is stably and permanently fixed on the side wall of the ink cartridge. Of course, the technical solutions of the present invention are not limited to the above embodiments, and those skilled in the art are within the scope of protection of the present invention without departing from the scope of the present invention.
