[0002] Ink cartridges are components in inkjet printers that supply printing ink and ultimately complete the printing process. They are essential parts of the printer. The ink cartridge is fixed to the side of the printer and connected to it via a tube, supplying ink to the printer. After a period of use, the ink cartridge needs to be replaced. First, the connection between the ink cartridge and the printer is disconnected, and then the new ink cartridge is connected to the printer. However, in the current replacement process, ink residue remains in the connecting tube, and ink can easily leak out during replacement, staining the desktop and hands. Therefore, a connector for ink cartridges is proposed. Utility Model Content

[0003] The purpose of this invention is to overcome the problem in the prior art that ink residue remains in the connecting tube when replacing ink cartridges, and the ink easily leaks out during replacement, staining the desktop and hands.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] In the description of this utility model, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, specific orientation structure, or operation. Therefore, they should not be construed as limitations on this utility model.

[0024] This embodiment provides a connector for ink cartridges, including a first outer shell 1 and a second outer shell 2. The first outer shell 1 and the second outer shell 2 are fixedly installed. A connecting rod 3 is installed on the side of the first outer shell 1, and a connecting rod 4 is installed on the side of the second outer shell 2. A sealing sleeve 5 and a sealing sleeve 6 are respectively provided at the connection point of the first outer shell 1 and the second outer shell 2. A spring 7 is provided inside the first outer shell 1, with one side of the spring 7 located on the side of the connecting rod. A liquid guide tube 8 is provided on the side of the spring 7, and a positioning rod 13 is provided at one end of the liquid guide tube 8 near the spring 7. The positioning rod 13 is inserted into the middle of the spring 7. An annular structure is provided on one end of the liquid guide tube 8 at the first outer shell 1, and the diameter of the annular structure is larger than the inner diameter of the sealing sleeve 5. One end of a heat-conducting rod passes through the sealing sleeve 5 and the sealing sleeve 6 and is located inside the second outer shell 2. A spring 9 is provided inside the second outer shell 2, and a sealing ball 10 is provided on one side of the spring 9. The diameter of the sealing ball 10 is larger than the diameter of the sealing sleeve 6, sealing the seal. One side of the ball 10 contacts the other side of the guide rod. The side wall of the liquid guide tube 8 near the blocking ball 10 is recessed with a liquid guide notch 11. The end of the liquid guide tube 8 near the spring 7 has a liquid guide hole 12. When the outer shell 1 and the outer shell 2 are not connected, the spring 9 controls the blocking ball 10 to block the sealing sleeve 6, preventing ink from flowing out through the sealing sleeve 6. The spring 7 controls the liquid guide tube 8 to press against the sealing sleeve 5. At this time, the liquid guide hole 12 is located inside the sealing sleeve 5, and the ink is located inside the outer shell 1. The ink cannot flow out through the liquid guide hole 12, that is, when replacing the ink cartridge, the ink will not flow out, avoiding contamination. When the outer shell 1 and the outer shell 2 are connected, the liquid guide tube 8 is inserted into the sealing sleeve 6, pressing the blocking ball 10 against the connecting rod 4. At the same time, the spring 7 is also compressed by the reaction force, and the liquid guide hole 12 of the liquid guide tube 8 moves backward, that is, the liquid guide hole 12 moves out from the sealing sleeve 5. At this time, the ink can flow through the liquid guide tube 8.

[0025] In one embodiment, specifically, the axes of connecting rod 3, connecting rod 4, and liquid guide tube 8 coincide.

[0026] In one embodiment, specifically, the outer casing 2 is provided with an inner liner ring 14, which is fixedly disposed on the side of the connecting rod 4 and sleeved on the outside of the spring 9 and the sealing ball 10.

[0027] In one embodiment, specifically, the inner surface of the second outer shell 2 is provided with symmetrical protrusion structures, the outer surface of the first outer shell 1 is provided with a groove structure corresponding to the protrusion structure, the groove structure is an L-shaped structure, and the side wall of the second outer shell 2 is provided with symmetrical through-hole structures, the opening structures being provided in correspondence with the protrusion structures.

[0028] In this embodiment, the working process of the connector for the ink cartridge is as follows: Connecting rod 3 and connecting rod 4 are respectively connected to the ink cartridge and the printer. When replacing the ink cartridge, bring outer shell 1 and outer shell 2 close together so that the protrusion structure on outer shell 2 aligns with the groove structure on outer shell 1. Then, press outer shell 1 into outer shell 2, that is, insert the protrusion structure into the groove structure. At the same time, the guide tube penetrates the sealing sleeve 2 6 and pushes open the sealing ball 10. Simultaneously, the guide tube receives a reaction force, the spring 7 is compressed, and the liquid guide tube 8 moves out from the sealing sleeve 5. Figure 5 As shown, the ink flows into the guide tube through the guide hole, then into the outer casing 2 through the liquid guide notch 11, and finally into the printer through the connecting tube 2, thus completing the installation of the connecting tube.

[0029] The above description is merely an example and illustration of the structure of this utility model. Those skilled in the art can make various modifications or additions to the specific embodiments described or use similar methods to replace them, as long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of this utility model.
