[0025] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1-5 As shown, a printer ink cartridge with smooth ink flow includes a cartridge body 1 and a cartridge cover 2. Several connecting cylinders 19 are fixedly disposed on the inner surface of the cartridge body 1, and connecting posts 20 adapted to the connecting cylinders 19 are fixedly disposed on the inner surface of the cartridge cover 2. The connecting posts 20 and the connecting cylinders 19 are connected by an interference fit, and the connecting posts 20 are inserted into the connecting cylinders 19 to seal and fix the cartridge body 1 and the cartridge cover 2.

[0027] The cartridge 1 has a mounting slot 7 for installing a chip, and a chip-holding slot 8 is provided on the side wall of the mounting slot 7. The chip is held in place on the cartridge 1 through the chip-holding slot 8, facilitating the installation and removal of the chip from the cartridge 1 and enabling the reuse of the cartridge 1. The end of the cartridge 1 has anti-slip texture 22 to facilitate insertion of the cartridge 1 into the printer. The side wall of the cartridge 1 has a locking block to secure the cartridge 1 inside the printer. The cartridge 1 and the cover 2 are made of ABS material with high transparency, making it easy to observe the ink content inside the cartridge 1.

[0028] The cartridge 1 has an ink filling port 3 and an ink outlet 4. The ink filling port 3 is located on the upper side wall of the end of the cartridge 1 that is outside the printer, and the ink outlet 4 is located on the end of the cartridge 1 that is inserted into the printer. A baffle 9 is provided on the cartridge 1, forming an ink outlet cavity with the side wall of the cartridge 1. The height of the baffle 9 is lower than the height of the cartridge 1 to facilitate ink entry into the ink outlet cavity. A top ball 23 is provided at the ink outlet 4 to block it, and an ink outlet spring is provided inside the ink outlet cavity to press the top ball 23 against the ink outlet 4. A limiting platform 10 is fixedly provided on the inner surface of the cartridge 1 to limit the movement of the ink outlet spring, and the limiting platform 10 is located inside the ink outlet cavity. The spring is engaged with the limiting platform 10 to improve its stability within the ink outlet cavity. After the cartridge 1 is inserted into the printer, pressure is applied to the top ball 23, causing it to move away from the ink outlet 4, compressing the ink outlet spring, and allowing ink to flow out from the ink outlet 4. After cartridge 1 is pulled out of the printer, top ball 23 blocks ink outlet 4 under the action of ink outlet spring, preventing ink from flowing out of cartridge 1.

[0029] The cartridge body 1 is provided with a ventilation structure to facilitate the smooth flow of ink within the cartridge body 1. The ventilation structure includes a vent 5, which is open to the atmosphere. An air outlet 13 is provided inside the cartridge body 1, and the vent 5 and air outlet 13 are connected by a connecting structure. The connecting structure includes a partition 11 surrounding the vent 5, and the partition 11 is fixedly connected to the cartridge body 1. The top of the partition 11 is flush with the top of the cartridge body 1 to prevent ink from entering the air cavity enclosed by the partition 11. An air inlet 12 is provided through the cartridge body 1, located within the air cavity. An air passage 16 is provided on the outer surface of the cartridge body 1, connecting the air inlet 12 and the air outlet 13.

[0030] A connecting platform 24 is fixedly installed on the outer surface of the housing 1, and the connecting platform 24 is located on both sides of the air passage 16. A sealing membrane is provided on the connecting platform 24 to close the opening of the air passage 16 on the surface of the housing 1, and the sealing membrane and the air passage 16 form a closed gas flow channel.

[0031] An air inlet assembly is provided at the air outlet 13 to allow gas to enter the cartridge 1. The air inlet assembly includes a fixed cylinder 14, which is located inside the cartridge 1 and fixedly connected to it. The fixed cylinder 14 is fitted over the air outlet 13. A notch 15 is provided on the top side wall of the fixed cylinder 14 to allow gas to pass through, and a one-way valve is provided inside the fixed cylinder 14 to allow gas to enter the cartridge 1. The one-way valve ensures that the gas in the air passage 16 smoothly enters the cartridge 1 while preventing ink from flowing out of the cartridge 1.

[0032] The cartridge body 1 has an internal pressurization structure that is connected to the air pipe on the printer. The pressurization structure includes an air bladder 17, which is located inside the cartridge body 1. One end of the air bladder 17 is connected to an air inlet 6 on the cartridge body 1, which is connected to the air pipe inside the printer. A pressure spring 18 is located inside the cartridge body 1, between the air bladder 17 and the cartridge cover 2. A limiting sleeve 21 for positioning the pressure spring 18 is provided on the cartridge cover 2.

[0033] In use, assemble cartridge 1 and cover 2 with ink inlet 3 facing upwards. Add ink to cartridge 1 through ink inlet 3. After adding ink, seal ink inlet 3 with a rubber stopper. Remove the rubber stopper at vent 5, allowing vent 5 to connect with the outside atmosphere. Insert cartridge 1 into the printer, insert the printer's air hose into air inlet 6, and insert the printer's printhead ink inlet into ink outlet 4. Remove top ball 23 from ink outlet 4. During printing, the printer's air hose pulses pressurized gas into air chamber 17. Under the action of pressure spring 18, air chamber 17 resets, squeezing the ink in cartridge 1. The ink enters the printhead through ink outlet 4. As ink flows out, the pressure inside cartridge 1 decreases, and atmospheric air enters cartridge 1 through vent 5, air inlet 12, air passage 16, air outlet 13, and one-way valve, increasing the air pressure inside cartridge 1 and promoting smooth ink flow.

[0034] Therefore, the printer ink cartridge with smooth ink output described in this utility model can solve the problem of poor ink output smoothness of existing ink cartridges.

[0035] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and not to limit it.
