[0025] like Figures 1 to 5 As shown, an ink cartridge with a built-in leak-proof sealing valve includes an ink cartridge body 1, an ink outlet 2 on the bottom surface of the ink cartridge body 1, a refill port 3 on the top surface of the ink cartridge body 1, an ink outlet sealing valve assembly 4 on the inner wall of the ink outlet 2, and an ink filling sealing valve assembly 5 on the inner wall of the refill port 3. The ink outlet sealing valve assembly 4 and the ink filling sealing valve assembly 5 are used to seal the ink outlet 2 and the refill port 3 respectively to prevent leakage. More specifically, ink is stored and supplied through the ink cartridge body 1. The ink outlet 2 is located on the bottom surface of the ink cartridge body 1 and is used to deliver ink to the print head of the printer. The filling port 3 is located on the top surface of the ink cartridge body 1 and is used to add ink. The ink outlet sealing valve assembly 4 is installed inside the ink outlet 2 to ensure the sealing of the ink outlet 2 after the ink cartridge body 1 is removed from the printer and to prevent ink leakage. The ink filling sealing valve assembly 5 is installed inside the filling port 3 to provide a seal during non-ink filling and to automatically close after ink filling is completed to prevent ink leakage through the filling port 3.

[0026] The surface of the ink cartridge body 1 is fixedly equipped with mounting ears 6 for mounting and securing the ink cartridge body 1. More specifically, the mounting ears 6 are fixedly installed on the surface of the ink cartridge body 1 to securely install the ink cartridge on a printer or other equipment. The mounting ears 6 provide stable mechanical support, ensuring that the ink cartridge will not loosen due to vibration or external force during use, thereby guaranteeing the reliability and sealing of the ink cartridge.

[0027] The ink outlet sealing valve assembly 4 includes a crossbeam 401 fixedly installed on the inner wall of the ink outlet 2, and a rectangular rod 402 movably inserted into the crossbeam 401. A sealing plate 403 is fixedly installed at the top of the rectangular rod 402. A first spring 404 is sleeved on the surface of the rectangular rod 402, and the two ends of the first spring 404 are fixedly installed with the opposite surfaces of the crossbeam 401 and the sealing plate 403, respectively. A mesh plate 405 is fixedly installed at the bottom of the rectangular rod 402. More specifically, when the ink cartridge body 1 is installed into the printer, it is inserted into the inlet and outlet 2 of the printer head. The inlet pushes the screen plate 405, the rectangular rod 402, and the sealing plate 403 to move vertically upward in the outlet 2, which stretches the first spring 404 and opens the opening of the sealing plate 403 and the outlet 2, allowing the ink in the ink cartridge body 1 to be delivered to the printer head. Conversely, when the ink cartridge body 1 is removed, the elastic force of the first spring 404 causes the screen plate 405, the rectangular rod 402, and the sealing plate 403 to move vertically downward in the outlet 2, and the sealing plate 403 seals the outlet 2 to prevent leakage.

[0028] The ink filling sealing valve assembly 5 is fixedly installed in the housing 501 on the inner wall of the filling port 3. An annular body 502 is slidably installed inside the housing 501. A second spring 503 is fixedly installed on the bottom inner side of the housing 501 and the bottom surface of the annular body 502. A sealing cover 504 is fixedly installed on the bottom surface of the annular body 502 and is vertically movably inserted into the housing 501. A through hole 505 is provided on the surface of the sealing cover 504. More specifically, during ink filling, the ink filling syringe is inserted into the housing 501, causing the annular body 502 and the sealing cover 504 to move vertically within the housing 501, compressing the second spring 503. This allows ink to be introduced into the ink cartridge 1 through the through hole 505 on the surface of the sealing cover 504 to the bottom of the housing 501. When the ink filling syringe is withdrawn, the second spring 503 causes the annular body 502 and the sealing cover 504 to return to their original positions and seal.

[0029] The sealing plate 403 has a convex cross-section and is made of corrosion-resistant rubber material. More specifically, the sealing plate 403 can fit tightly against the end of the ink outlet 2, providing good sealing performance, while the corrosion-resistant rubber material can resist the chemical erosion of the ink and extend its service life.

[0030] When not in ink-filled, the bottom surface of the sealing cover 504 is flush with the bottom surface of the housing 501. More specifically, the elastic force of the second spring 503 automatically achieves the flushing of the bottom surfaces of the sealing cover 504 and the housing 501 for sealing, eliminating the need for manual operation by the user and improving the convenience and reliability of the sealing.

[0031] In summary: Ink is stored and supplied through the ink cartridge body 1. The ink outlet 2 is located on the bottom surface of the ink cartridge body 1 and is used to deliver ink to the print head of the printer. The refill port 3 is located on the top surface of the ink cartridge body 1 and is used to add ink. The ink outlet sealing valve assembly 4 is installed inside the ink outlet 2 to ensure the sealing of the ink outlet 2 after the ink cartridge body 1 is removed from the printer, preventing ink leakage. The ink filling sealing valve assembly 5 is installed inside the refill port 3 to provide a seal during non-ink filling processes and automatically closes after ink filling is completed, preventing ink leakage through the refill port 3.
