Description
Technical Field
The invention relates to the technical field of ink boxes, in particular to an ink box, an ink box unit and an ink jet printing head.
Background
The ink jet printing is a brand new digital printing technology which appears in recent years, ink drops are ejected from nozzles to the surfaces of various media through thrust generated by micro-pressure electricity or thermal bubbles, and the ink jet printing device has the advantages of high printing speed, flexible operation, low noise, high output graphics and image quality and the like, but because the ink filling quantity in the original ink box is very small, the price of the original ink box is very high, the regeneration ink box which is refitted from the original ink box appears in the market, and after the ink in the ink box is used, the ink can be manually injected into the ink box, so that the ink box can work again.
A patent also appears in the prior art to relate to an ink cartridge, an ink cartridge unit and an inkjet printhead, such as a chinese patent with application number CN2017101134685, which discloses an ink cartridge for a printer, comprising an ink reservoir, a partition, an air duct, a sponge, and a printer nozzle; the partition plate divides the ink storage chamber into a left chamber and a right chamber; the upper surface of the right chamber is provided with an ink adding port; the volume of the left chamber is larger than that of the right chamber; the upper end part of the partition board is connected with the upper surface of the ink storage chamber in a sealing way; the lower end part of the partition board is in non-contact with the lower surface of the ink storage chamber, so that the left chamber is communicated with the right chamber.
In the prior art, the ink storage chamber, the partition plate, the air duct and the sponge body are arranged, so that the application reduces the waste of ink and can ensure the very stable ink supply of the spray head; however, when the ink box in the prior art is used for adding ink, impurities doped in the ink can enter the ink box along with the ink, when the ink flows in the ink box, the impurities can enter the ink outlet pipe along with the ink, and along with long-time use of the ink box, the impurities in the ink can be accumulated in the ink outlet pipe, so that the ink outlet is blocked, the ink outlet is uneven even not to be discharged when the ink box is used, and the working efficiency of the ink box is poor.
In view of the above, the present invention provides an ink cartridge, an ink cartridge unit, and an inkjet printhead, which solve the above-mentioned problems.
Disclosure of Invention
In order to make up the deficiency of the prior art, the problem that impurities doped in the ink enter the ink box along with the ink when the ink box is filled in the prior art, the impurities enter the ink outlet pipe along with the ink when the ink flows in the ink box, and the impurities in the ink can be accumulated in the ink outlet pipe along with long-time use of the ink box, so that an ink outlet is blocked, the ink outlet is uneven even not to be discharged when the ink box is used, and the working efficiency of the ink box is poor is solved; the invention provides an ink box, an ink box unit and an ink jet printing head.
The technical scheme adopted for solving the technical problems is as follows: an ink box comprises a box body, an ink inlet pipe and an ink outlet pipe; the upper and lower inner walls of the box body are respectively fixedly connected with a filter plate, a gap is reserved between the two filter plates, a floating block is arranged between the two filter plates, and the floating block is in sliding connection with the side walls of the two filter plates;
the ink inlet pipe and the ink outlet pipe are arranged diagonally, the two filter plates are positioned between the ink inlet pipe and the ink outlet pipe, a gap is formed between the lower end of the filter plate close to the ink inlet pipe and the inner wall of the lower side of the box body, and a gap is formed between the filter plate close to the ink outlet pipe and the inner wall of the upper side of the box body;

An ink box unit comprises a box body 1 and an ink inlet pipe 11, wherein a magnetic filter screen 111 is fixedly connected inside the ink inlet pipe 11;
in use, by making the ink cartridge unit include the cartridge body 1 and the ink inlet pipe 11, and the magnetic filter screen 111 is fixedly connected inside the ink inlet pipe 11, when ink is injected into the cartridge body 1 through the ink inlet pipe 11, the ink passes through the magnetic filter screen 111 inside the ink inlet pipe 11, and contacts with the magnetic filter screen 111, so that metal mechanical impurities in the ink are adsorbed on the magnetic filter screen 111, and the amount of metal impurities entering the cartridge body 1 is reduced.
An inkjet printhead adapted for use with one of the cartridge units described above.
The specific working procedure is as follows:
the ink enters the box body 1 through the ink inlet pipe 11, the ink inlet pipe 11 is positioned at the left sides of the two filter plates 12, when the ink enters the box body 1, the liquid level of the ink in the box body 1 gradually rises, the ink entering the box body 1 flows from the direction of the ink inlet pipe 11 to the ink outlet pipe 2, and impurities in the ink are blocked by the filter plates 12 in the flowing process of the ink; when ink is filled into the ink tank through the ink inlet pipe 11, the ink liquid level in the ink tank body 1 rises, so that a floating block 13 between two filter plates 12 rises along with the ink liquid level, the floating block 13 floats upwards between the two filter plates 12, along with the ink tank work, the liquid level in the ink tank body 1 falls, the floating block 13 descends along with the liquid level, the floating block 13 lifts up and down between the two filter plates 12, and simultaneously, the two sides of the floating block 13 scrape the side surfaces of the filter plates 12, so that the filtering efficiency of the filter plates 12 on impurities in the ink is increased, and when the ink liquid level rises, the floating block 13 ascends, and the scraper 23 fixedly connected with the floating block 13 through the pull rope 24 descends, and as the scraper 23 is in threaded connection with the threaded rod 21, the scraper 23 rotates when the scraper 23 descends, the pull rope 24 winds on the threaded rod 21, and the scraper 23 rotates while descending, so that the inner wall of the ink outlet pipe 2 scrapes; and along with the lowering of the liquid level, the floating block 13 descends, the first ring 22 is pulled to move upwards when the floating block 13 descends, and when the first ring 22 moves upwards, the pull rope 24 is separated from the threaded rod 21, so that the scraping plate 23 on the first ring 22 scrapes the inside of the ink inlet pipe 11 for the second time.
