Description

Technical Field

[0001] This utility model relates to the field of ink cartridge technology, and in particular to a handleless ink cartridge. Background Technology

[0002] Ink cartridges are components in printing equipment used to store ink and play a very important role in printers. An ink cartridge consists of the cartridge body and the ink reservoir. When the ink in the cartridge body is depleted, the cartridge body needs to be removed for replacement. Alternatively, if the printer will not be used for an extended period, the cartridge body should be removed to prevent ink deterioration and to protect the printer head.

[0003] Existing ink cartridges require a handle to be installed on their surface for easy disassembly. By pressing the other end of the handle, the positioning support block is lifted, allowing the ink cartridge to be removed. However, the handle is costly to produce and prone to damage during use, which negatively impacts the user experience. To address the shortcomings of existing technology, we propose a handle-less ink cartridge. Utility Model Content

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] Example 1, as Figures 1-5 As shown, a handleless ink cartridge facilitates the installation of the cartridge body 6 by means of a first mounting slot 2 and a second mounting slot 3. The first mounting slot 2 can accommodate a black ink cartridge, and the second mounting slot 3 can accommodate a color ink cartridge. During installation, the cartridge body 6 is inserted into the first mounting slot 2, and the spring plate 8 is engaged in the slot 5. As the cartridge body 6 is continuously pushed into the first mounting slot 2, the spring plate 8 is compressed until the cartridge body 6 is fully installed in the first mounting slot 2. At this point, the spring plate 8 limits the cartridge body 6, ensuring that it is tightly secured inside the first mounting slot 2. The cartridge body 6 is connected to the printer via contacts on the surface of a chip 24. When the printer's ink suction structure contacts the ink nozzle 13, it draws out the ink absorbed inside the sponge liner 16 and sprays it onto the paper surface through the ink nozzle 13.

[0023] Example 2, as Figures 1-5As shown, a handleless ink cartridge has a filter 17 secured in the inner wall of a fixing plate 23. A filter paper 18 is then placed on top of the filter 17. Next, a sponge liner 16 soaked in ink is placed inside the cartridge body 6, with the lower part of the sponge liner 16 contacting the upper surface of the fixing plate 23. A dustproof plate 7 is then placed above the cartridge body 6, with a fixing block 15 secured inside a limiting groove 14. This allows the dustproof plate 7 to be installed above the cartridge body 6. Air is vented through a vent 9 to prevent pressure differentials. When a user needs to remove the cartridge body 6 from the first mounting groove 2, the front end of the spring plate 8 is pressed slightly downwards, preventing the upper surface of the spring plate 8 from contacting the groove 5. The user can then hook the pull ring 19 with their finger to remove the cartridge body 6 from the first mounting groove 2. This method is very convenient and quick, facilitating cartridge body 6 replacement.

[0024] It should be noted that this utility model is a handleless ink cartridge. In use, firstly, the filter 17 is secured in the groove on the inner wall of the fixing plate 23. Then, the filter paper 18 is placed on top of the filter 17. The operator pre-soaks the sponge liner 16 with ink, then places the sponge liner 16 inside the ink cartridge body 6, ensuring its lower surface contacts the upper surface of the fixing plate 23. The fixing block 15 below the dustproof plate 7 is secured inside the limiting groove 14, thus connecting the dustproof plate 7 to the ink cartridge body 6. The chip 24 (previously used) is then glued to the side of the ink cartridge body 6. The surface contacts connect to the printer. When the staff needs to replace the ink cartridge body 6, insert the blade into the disassembly slot 12 and rotate the blade to push out the dust cover 7. Place the reset spring 22 inside the movable pin 21, and then insert the two sets of movable pins 21 into the fixing holes 20 on the inner wall above the pull ring 19. During installation, press the two sets of movable pins 21 inward until the protrusion of the pull ring 19 can engage with the groove above the fixing slot 11, and until one end of the movable pin 21 is inserted into the fixing hole 20 on the inner wall above the fixing slot 11, the assembly of the pull ring 19 is completed.
