Description

Technical Field

[0001] This utility model relates to the field of printer consumables technology, and in particular to an ink cartridge that prevents ink sedimentation. Background Technology

[0002] As an indispensable output device in modern offices and homes, printers' core function is to convert digital information into paper documents through precise mechanical structures. Inkjet printers, as one of the mainstream types, rely on ink cartridges as key components for ink storage and supply. The interior of an ink cartridge typically contains porous materials or a sponge structure to temporarily hold ink and continuously supply it to the print head through the ink outlet, thus ensuring the continuity and stability of the printing process.

[0003] Existing ink cartridges require manual intervention to resolve ink sedimentation issues before use. Because ink contains pigments or dyes, additives, and other components, it is prone to stratification or sedimentation when left to stand. After purchasing a new cartridge, users typically need to manually shake or invert the cartridge to redisperse the sediment in the solvent before installing it in the printer. While this temporarily alleviates uneven ink supply caused by sedimentation, it is essentially a passive solution relying on active user intervention.

[0004] If an existing ink cartridge remains in a non-working state for an extended period after installation, the ink inside will gradually settle due to gravity, leading to problems such as broken lines and color deviation during printing. Users may neglect to shake the ink cartridge in time or shake it insufficiently, resulting in a decline in initial print quality. Repeated shaking may accelerate the aging of the ink cartridge seals and increase the risk of ink leakage. Utility Model Content

[0005] To overcome the drawback of needing to manually shake the ink cartridge to allow it to settle, this invention provides an ink cartridge designed to prevent ink sedimentation, thus addressing the aforementioned shortcomings.

[0006] An ink cartridge designed to prevent ink sedimentation includes an ink cartridge, a stirring rod, a mounting plate, a fixing screw, a motor, and a cleaning component. The stirring rod is rotatably connected inside the ink cartridge, and the mounting plate is connected to the end of the ink cartridge. One end of the motor, equipped with a fixing screw, contacts the mounting plate, and the fixing screw is threadedly connected to the mounting plate. The output shaft of the motor is connected to the stirring rod, and a cleaning component for cleaning the stirring rod is located at the top inside the ink cartridge.

[0007] Furthermore, the cleaning components include a scraper, a protrusion, a torsion spring, and a baffle. The scraper is rotatably connected to the top of the ink cartridge, and the protrusion is connected to the bottom of the scraper. The protrusion is slidably connected to the surface of the stirring rod. A torsion spring is sleeved on the rotating shaft of the scraper. One end of the torsion spring is connected to the ink cartridge, and the other end is connected to the scraper. A baffle is connected to the top of the ink cartridge, and the baffle is in a limiting fit with the scraper.

[0008] Furthermore, it also includes a buffer pad, with the buffer pad connected to the side of the baffle facing the scraper, and the scraper and the buffer pad are pressed together.

[0009] Furthermore, it also includes a guide ring, which is connected to the side of the mounting plate away from the ink cartridge, and the guide ring is slidably connected to the motor.

[0010] Furthermore, it also includes limit plates, with several limit plates connected to the motor, and the limit plates are matched with the fixing screws for limiting.

[0011] Furthermore, it also includes rubber strips, with several rubber strips connected to the outside of the motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The stirring rod is driven by a motor to rotate continuously in one direction, thereby achieving the automatic stirring function of ink and achieving the purpose of continuously dispersing precipitates without manual intervention.

[0014] 2. By sliding contact between the bottom protrusion of the scraper and the surface of the stirring rod, combined with the linkage design of the torsion spring energy storage reset and the buffer pad collision emergency stop, the automatic removal function of residue on the surface of the stirring rod is realized, thereby reducing ink adhesion and deposition.

[0021] 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.

[0022] Example: An ink cartridge that prevents ink sedimentation, such as Figures 1-5 As shown, the device includes an ink cartridge 1, a stirring rod 2, a mounting plate 3, fixing screws 4, a motor 5, and a cleaning assembly. The ink cartridge 1 is installed inside the printer. The stirring rod 2 is rotatably connected to the cavity inside the ink cartridge 1 for containing ink. The mounting plate 3 is connected to the end of the ink cartridge 1. The end of the rotating shaft of the stirring rod 2 passes through the end of the ink cartridge 1 and is provided with a spline groove. Several fixing screws 4 are connected to the outer ring of the protruding side of the output shaft of the motor 5. One end of the motor 5 with the fixing screws 4 contacts the mounting plate 3. The fixing screws 4 are threadedly connected to the mounting plate 3. The fixing screws 4 and the threaded holes of the mounting plate 3 cooperate to achieve axial positioning of the motor 5. The output shaft of the motor 5 is provided with a spline and is keyed to the rotating shaft of the stirring rod 2. A cleaning assembly for cleaning residual ink and sediment on the surface of the stirring rod 2 is provided at the top of the ink cartridge 1.

[0023] like Figures 2-5 As shown, the cleaning assembly includes a scraper 6, a protrusion 7, a torsion spring 8, and a baffle 9. The scraper 6 is rotatably connected to the top of the ink cartridge 1, and the protrusion 7 is connected to the bottom of the scraper 6. The protrusion 7 is slidably connected to the surface of the stirring rod 2. The torsion spring 8 is sleeved on the rotating shaft of the scraper 6. One end of the torsion spring 8 is connected to the ink cartridge 1, and the other end is connected to the scraper 6. The baffle 9 is connected to the top of the ink cartridge 1 to limit the rotation angle of the scraper 6. The baffle 9 is in a limiting fit with the scraper 6.

[0024] like Figure 3 As shown, it also includes a buffer pad 10. The buffer pad 10 is connected to the side of the baffle 9 facing the scraper 6. The scraper 6 and the buffer pad 10 are pressed together. The buffer pad 10 is made of silicone material to absorb the impact of the scraper 6 resetting and reduce collision noise.

[0025] like Figure 5 As shown, it also includes a guide ring 11. The mounting plate 3 is connected to the guide ring 11 on the side away from the ink cartridge 1. The inner ring of the guide ring 11 is provided with an outward inclined surface. The guide ring 11 is slidably connected to the motor 5. The inclined surface enables the motor 5 to be quickly and blindly inserted, reducing the installation difficulty for users.

[0026] like Figure 5 As shown, it also includes a limiting plate 12. Several limiting plates 12 are connected to the outer ring of the motor 5 along the disassembly path of the fixing screw 4. The limiting plate 12 is matched with the fixing screw 4 to limit and prevent the fixing screw 4 from falling off or being lost during disassembly.

[0027] like Figure 5 As shown, it also includes adhesive strips 13. Several adhesive strips 13 are connected to the outside of the motor 5. The adhesive strips 13 increase the friction of the fingers, and the anti-slip texture improves the grip stability during disassembly.

[0028] The stirring rod 2 is located only in the ink-containing area of ​​the ink cartridge 1, and its shaft is sealed at the connection with the ink cartridge 1 to prevent leakage. A dedicated motor 5 is included with the printer. Before installing the stirring rod 2, the motor 5 must be pushed in along the guide ring 11 on the back of the mounting plate 3. The inclined inner wall of the guide ring 11 guides the output shaft of the motor 5 to accurately insert into the spline groove of the stirring rod 2's shaft, achieving power transmission. The user then rotates the fixing screw 4 clockwise, gradually tightening the screw end in the threaded engagement with the mounting plate 3 until the end of the motor 5 with the fixing screw 4 is completely flush with the surface of the mounting plate 3. At this point, the motor 5 is stably fixed to the mounting plate 3. After power is connected, the motor 5 starts, driving the stirring rod 2 to rotate continuously in one direction via the spline connection. The blades of the stirring rod 2 agitate the settled ink particles, redispersing them in the solvent. When the stirring rod 2 rotates to the top, the edge of the blade contacts the protrusion 7 at the bottom of the scraper 6. The kinetic energy of the stirring rod 2 drives the protrusion 7 and the scraper 6 to rotate around the axis towards the inner wall of the ink cartridge 1. During this process, the torsion spring 8 on the rotating shaft of the scraper 6 is twisted and stores energy. As the scraper 6 rotates, the protrusion 7 scrapes away the ink or sediment adhering to the surface of the stirring rod 2. Since the stirring rod 2 rotates only in one direction, its working surface always remains in contact with the ink and sediment. When the stirring rod 2 disengages from the protrusion 7, the torsion spring 8 releases its elastic potential energy to drive the scraper 6 to return to its original rotation until the side of the scraper 6 collides with the buffer pad 10 on the surface of the baffle 9. The buffer pad 10 absorbs the remaining kinetic energy of the scraper 6 through elastic deformation, allowing the scraper 6 to stop stably in its initial position. At the same time, the vibration generated by the collision causes the ink remaining on the protrusion 7 to drip off. After the ink has been dispersed, the user disconnects the power to the motor 5 and rotates the fixing screw 4 counterclockwise until it is completely detached from the mounting plate 3. At this point, the end of the screw is blocked by the limiting plate 12 on the outer ring of the motor 5 and will not fall off the motor 5. The user presses the rubber strip 13 on the outside of the motor 5 with their finger to increase friction, and the motor 5 can be removed from the guide ring 11. Finally, the ink cartridge 1 can be inserted into the printer for use.

[0029] The printer has a mounting position for the motor 5, which can be directly installed inside the printer. The start and stop of the motor 5 can be directly controlled by the printer. This is suitable for scenarios where the printer has the ink cartridge 1 but is used very infrequently. When the ink cartridge 1 is replaced, the motor 5 needs to be removed and disassembled at the same time.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
