DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] As Figures 1-5 shown, the present utility model provides an anti - clogging ink cartridge for an inkjet printer, mainly used for the ink cartridge of an inkjet printer. This ink cartridge is a monochrome printing ink cartridge, and it has the effects of filling ink internally and printing ink jets.

[0023] The specific structure of the ink cartridge mainly includes a cartridge body 1. Inside the cartridge body 1, there are an ink chamber 2, a liquid injection chamber 3, and two purification chambers 4. When the chambers are distributed inside the cartridge body 1, the liquid injection chamber 3 and the two purification chambers 4 are both arranged below the ink chamber 2, and the liquid injection chamber 3 is arranged between the two purification chambers 4. Both sides of the purification chambers 4 are communicated with the ink chamber 2 above. There are multiple communicating liquid holes 5 between the liquid injection chamber 3 and the two purification chambers 4. Ink flows in the ink chamber 2 to the purification chambers 4 on both sides. The ink in the purification chambers 4 can purify the impurities in the ink by itself before entering the liquid injection chamber 3, and then enters the liquid injection chamber 3 through the liquid holes 5 for printing use.

[0024] In order to better precipitate the ink in the purification chamber 4, the position of the liquid hole 5 leading from the purification chamber 4 to the liquid injection chamber 3 is set at the middle position of the purification chamber 4, to prevent the impurities at the bottom of the purification chamber 4 from being brought into the liquid injection chamber 3 due to the too low position of the liquid hole 5, and reduce the damage of the impurities to the nozzle. At the same time, a convex part 14 protruding downward to block the liquid injection chamber 3 is provided at the connection between the ink chamber 2 and the purification chamber 4. The convex part 14 prevents the impurities falling from the ink chamber 2 from approaching the liquid hole 5 and being directly sucked into the liquid injection chamber 3, increases the probability of the impurities falling into the purification chamber 4 for purification, and improves the purification effect.

[0025] A nozzle 6 for inkjet is assembled at the bottom of the cartridge body 1 and is communicated with the liquid injection chamber 3. An ink transmission channel 13 for transmitting ink and communicating between the nozzle 6 and the liquid injection chamber 3 is also provided inside the cartridge body 1. A chip 7 for driving and controlling the inkjet of the nozzle 6 is provided on one side of the cartridge body 1. The inkjet of the nozzle 6 is controlled by this chip 7. In order to better connect the nozzle 6 and the chip 7, an ink ribbon 11 is connected between them for conducting electricity to drive and control the inkjet action, and the chip 7 can be fixed on the ink ribbon 11 by welding. At the same time, an ink ribbon placement groove 12 for placing and leveling the ink ribbon 11 is provided on the surface of the cartridge body 1, and the ink ribbon 11 can be fixed in the ink ribbon placement groove 12 by gluing.

[0026] A liquid injection port 8 communicated with the ink chamber 2 is provided at the top of the cartridge body 1. The liquid injection port 8 is provided with a sealing plug 9. The liquid injection port 8 is a position for facilitating the user to inject ink into the ink chamber 2. After the ink injection is completed, it is sealed by the sealing plug at the opening.

[0027] A perspective window 10 penetrating to the ink chamber 2 is provided on one side of the cartridge body 1. The perspective window 10 has a transparent structure and can be composed of transparent acrylic or a glass sheet, which is convenient for the user to monitor in real time and clearly know the remaining amount of ink inside the ink chamber 2.

[0028] Compared with the traditional technology, for the ink cartridge provided by this technical solution, before the ink enters the liquid injection chamber 3 and flows to the nozzle 6, purification chambers 4 for precipitating and purifying the impurities in the ink are provided on both sides. The impurities suspended in the ink are fully purified and removed before being transmitted to the nozzle 6, avoiding the impurities in the ink from flowing into one end of the nozzle 6 and damaging the nozzle 6, and prolonging the service life of the nozzle 6.

[0029] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention, and any figure mark in the claims should not be regarded as limiting the claims involved.
