[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5 As shown, the present invention provides a printer ink cartridge, comprising an ink cartridge body 1 and a positioning platform 2. The ink cartridge body 1 has an internal cavity 11 for holding ink.

[0025] Furthermore, the positioning platform 2 is located at the bottom of the ink cartridge body 1, and the positioning platform 2 is provided with a positioning structure 21 for cooperating with the printer. It should be understood that in some specific situations, the ink cartridge needs to be removed from the printer (such as during ink cartridge maintenance), which means that the ink cartridge body 1 needs to be reinstalled into the printer. During the reinstallation process, the positioning structure on the positioning platform 2 at the bottom of the ink cartridge body 1 can cooperate with the printer, thereby allowing the ink cartridge body to be securely installed in the printer.

[0026] Preferably, the positioning structure 21 includes a buckle 211 and a slot 212 spaced apart on the positioning platform 2. It should be understood that when the ink cartridge body 1 is installed on the printer, the buckle 211 and the slot 212 will be positioned and locked in the printer, so that the ink cartridge body 1 can be securely installed.

[0027] Preferably, the layout of the latch 211 and the slot 212 is asymmetrical about the central axis of the ink cartridge body 1.

[0028] Preferably, the asymmetrical layout of the buckle 211 and the slot 212 is as follows: the buckle 211 is disposed on one side of the positioning platform 2, and the slot 212 is disposed on the other side of the positioning platform 2.

[0029] See Figure 3 and Figure 4 It is worth noting that the latch 211 is on one side of the positioning platform 2 (not in the center of the positioning platform 2), while the slot 212 is on the other side of the positioning platform 2. Thus, the latch 211 and the slot 212 together form an anti-misinstallation structure. When the user tries to install the ink cartridge body 1 in the wrong direction, the latch 211 or the slot 212 will interfere with the corresponding structure inside the printer, making it impossible to install smoothly. This can effectively prevent people from installing the ink cartridge body 1 backwards, thus playing a protective role.

[0030] In this embodiment, the positioning platform 2 extends outward to form an extension platform 22, and the side wall of the extension platform 22 is provided with a connector 23 that connects to the buckle 211. It should be understood that in order to reduce weight while ensuring the strength of the ink cartridge body 1, the connector 23 provided between the extension platform 22 and the buckle 211 can greatly increase the stress on the entire positioning platform 2, thereby improving the bending resistance of the positioning platform 2.

[0031] Furthermore, one side of the extension platform 22 is provided with a plurality of first through holes 24 communicating with the receiving cavity 11 to form a plurality of ink outlets 3.

[0032] Preferably, the card slot 212 has a second through hole 25 communicating with the receiving cavity 11 to form an ink inlet 4 that is independent of the ink outlet 3. That is, the ink inlet 4 is located in the card slot 212, while the ink outlet 3 is located at the extension platform 22. It should be understood that the ink outlet 3 is formed by the extension platform 22 and the first through hole 24.

[0033] Preferably, the ink inlet 4 and the ink outlet 3 are independent tubular structures. Of course, the ink inlet 4 and the ink outlet 3 can also be used with square or irregular shapes.

[0034] In this embodiment, the extension platform 22 and the positioning platform 2 are integrally formed, and the side of the extension platform 22 away from the ink cartridge body 1 and the side of the buckle 211 away from the ink cartridge body 1 are on the same plane. That is to say, the surface of the ink outlet 3 (i.e., the extension platform 22) that needs to contact the printer is on the same plane as the buckle 211.

[0035] It should be noted that the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.
