Description

Technical Field

[0001] The utility model relates to the technical field of printing equipment, and more specifically to an anti-blocking ink cartridge with a blocking detection function. Background Art

[0002] Modern ink cartridges mainly refer to the parts used to store printing ink and finally complete printing in inkjet printers. With the development of science and technology, some ink cartridges with intelligent detection have also been developed; ink cartridges with intelligent detection functions can detect some data of the ink cartridge, such as the liquid level of the ink, whether the ink cartridge is blocked, etc. Due to the difference in quality, the ink will have more or less some granular impurities, which can easily cause the ink outlet to be blocked. And these impurities are very easy to stick to the inner wall of the ink cartridge, resulting in inaccurate intelligent detection results, so the existing intelligent detection ink cartridges usually use some filtering devices to remove impurities before use. After the ink is used up, the impurities in the filtering device are removed, but the filtering device in the existing intelligent detection ink cartridge is usually fixed inside the ink cartridge. When removing impurities, it is not convenient to disassemble, which affects the efficiency of removing impurities and leaves a lot of residual impurities, affecting the next use.

[0003] In view of the above problems, regarding the technical problem of the inconvenience of disassembling the existing ink cartridge filter device, after a lot of searches, a patent number CN212353291U with intelligent detection and anti-clogging ink cartridge was found, including an ink cartridge body, a mounting groove is provided in the middle of the upper surface of the ink cartridge body, a slot is provided in the middle of the inner wall at the bottom of the mounting groove, and the opening edge of the top of the slot is set in an arc shape, a water outlet groove is provided in the middle of the bottom of the slot, a filter housing is movably provided inside the mounting groove, a filter groove is provided in the middle of the lower surface of the filter housing, the bottom of the filter housing extends to the inside of the slot, a connecting groove is provided at one end of the two side walls of the filter housing located inside the slot, a square groove is provided at the bottom of the connecting groove, and a card slot corresponding to the connecting groove is provided on the inner walls on both sides of the slot, a long groove is provided at the bottom of the card slot, a through groove is provided at the bottom of the long groove, and the bottom of the through groove passes through the ink cartridge body and extends to the outside of the ink cartridge body; however, the technical solution provided by the patent has the following problems:

[0004] (1) The filter device in the ink cartridge occupies a large volume, and the filter screen is fixedly connected to the filter device, making it very inconvenient to replace the filter screen. At the same time, when removing the filter device of the ink cartridge, it is necessary to press the bumps on both sides at the same time to operate, which is not convenient for users with smaller hands to operate. If the filter device is operated with both hands, it will pop up, which is difficult to control when the filter device pops up, and may cause residual ink to splash out;

[0005] (2) There is no device to prevent air from entering the ink outlet of the ink cartridge. When the printer is not working, the ink comes into contact with the air, which can easily cause the ink to condense at the ink outlet and block the ink outlet.

[0006] The filter assembly of the utility model occupies a small volume and is easy to operate when taken out, is not easy to leak ink, and can prevent air from entering from the ink outlet, causing the ink to solidify at the ink outlet and block the ink outlet. Utility Model Content

Then, ink is injected into the shell 1 from the ink filling port 4. When the printer is working, the ink inside the shell 1 flows out from the ink outlet 15, the internal pressure of the shell 1 is reduced, and the external gas enters the ink cartridge through the vent on the top cover 2, pushing the plug plate 10 to move, thereby making the ink-absorbing cotton 13 always absorb ink. At the same time, the elastic limit rod 11 plays a role of balancing the pressure in this process, so that the plug plate 10 does not tilt during the movement. When ink is discharged, suction is generated under the ink outlet 15, and the anti-blocking plate 1501 rotates under the suction. , open the ink outlet 15 to discharge ink. When the printer is finished working, the suction disappears, and the anti-blocking plate 1501 returns to its original state under the action of the micro spring 1502, closing the ink outlet to prevent air from entering. When the ink outlet 15 is blocked, the condensed ink block will cause the anti-blocking plate 1501 to be unable to close. At this time, the anti-blocking plate 1501 on the right cannot be restored, and the right side will continue to tilt up, lifting the indicator plate 14. The staff only needs to observe whether the indicator plate 14 is always in a high position to determine whether ink blockage occurs. When it is necessary to remove the top cover 2, just turn the knob 3, and the knob 3 pushes the rack 6 to move. The rack 6 squeezes the limit column 501 to move downward, so that the claw 503 in the buckle 5 tilts and shrinks toward the inside of the buckle 5, so that the claw 503 is separated from the side wall of the slot 101, and then the reset spring 102 will bounce the buckle 5 together with the top cover 2 upward.
