[0036] See also Figure 1-Figure 4 As shown, a print head self-cleaning device of an inkjet printer of this embodiment includes:

[0037] A base 11 having a sliding guide groove 12;

[0038] The box body 1 is slidably mounted in the sliding guide groove 12 of the base 11. The box body 1 has a sealed chamber 2. The print head 10 of the inkjet printer moves toward the box body 1 and pushes the box body 1 to slide along the sliding guide groove 12. During the sliding process of the box body 1, the sealed chamber 2 is driven to rise and surround the print head 10.

[0039] The first elastic member 8 is arranged between the bottom of the box body 1 and the base 11. The first elastic member 8 is stretched and deformed when the box body 1 slides and drives the sealing chamber body 2 to rise, thereby providing a downward pulling elastic force for the box body 1 to return to its original position.

[0040] In the present embodiment, the print head self-cleaning device of an inkjet printer moves the print head 10 to the box body 1 after printing is completed, and the sealed chamber 2 of the box body 1 rises to surround the print head 10, so that the print head 10 is in a relatively sealed environment, and the residual ink on the print head is kept moist to prevent the residual ink from drying and clogging the print head. Therefore, the present embodiment of the print head self-cleaning device of an inkjet printer realizes the cleaning and maintenance of the print head 10 of the inkjet printer and prevents the print head from being clogged.

[0041] In addition, the print head self-cleaning device of an inkjet printer in this embodiment realizes the automatic return of the box body 1 through the first elastic member 8 when the print head 10 leaves the box body 1 for printing, so that the print head 10 is cleaned and maintained when it returns to the box body 1 again.

[0042] Specifically, the first elastic member 8 described in this embodiment is a compression spring.

[0043] As an optional implementation of this embodiment, a print head self-cleaning device of an inkjet printer of this embodiment includes a second elastic member 7, which is arranged between the bottom of the box body 1 and the base 11 along the horizontal sliding direction of the box body 1. The second elastic member 7 is stretched and deformed in the horizontal direction when the box body 1 slides along the sliding guide groove 12, providing horizontal elastic force when the box body 1 returns to its original position.

[0044] Specifically, the second elastic member 7 described in this embodiment is a tension spring.

[0045] As an optional implementation of this embodiment, the box body 1 of this embodiment has a waste ink bin 3, the sealed bin body 2 is installed in the waste ink bin 3, and an ink outlet 5 is provided on the bottom wall of the sealed bin body 2. In this way, the residual ink on the print head 10 drips into the sealed bin body 2 and is discharged into the waste ink bin 3 through the ink outlet 5 of the sealed bin body 2, so that the residual ink is prevented from accumulating too much in the sealed bin body 2, which may cause contamination of the print head 10.

[0046] In addition, the sealing chamber body 2 of this embodiment is a rubber sealing chamber body, which can improve the sealing performance between the printing nozzle 10. The rubber sealing chamber body of this embodiment is detachably installed in the waste ink chamber 3, and the waste ink chamber 3 can be cleaned by disassembling the rubber sealing chamber body.

[0047] Furthermore, in order to facilitate the cleaning of the waste ink bin 3, an ink absorbing cotton sheet is provided in the waste ink bin 3 of the present embodiment. Since the residual ink of the print head 10 is very small, it generally does not accumulate in large quantities. Therefore, by providing the ink absorbing cotton sheet in the waste ink bin 3 of the present embodiment, the residual ink discharged by the sealed bin body 2 can be completely absorbed. When cleaning the waste ink bin 3, the ink absorbing cotton sheet can be directly discarded and replaced with a new one.

[0048] As an optional implementation of this embodiment, a scraper 4 is provided on one side of the sealed chamber 2 in the box body 1, and when the print head 10 of the inkjet printer moves toward the box body 1, it first contacts with the top of the scraper 4 for scraping and cleaning, and then contacts with the box body 1 to push it to slide along the sliding guide groove 12. In this embodiment, the scraper 4 can realize self-cleaning of the print head 10 to prevent foreign matter from adhering to the print head 10.

[0049] Furthermore, the angle between the arrangement direction of the scraper 4 and the horizontal movement direction of the print head 10 in this embodiment is less than 90°. In this way, the contact between the print head 10 and the scraper 4 is gradually increased from point to surface, avoiding the print head 10 directly "colliding" with the scraper 4 when the print head 10 is vertical to the scraper 4.

[0050] As an optional implementation of this embodiment, a striker 6 is provided in the box body 1 on the other side of the sealed chamber body 2 , and the print head 10 moves toward the box body 1 and abuts against the striker 6 , pushing the box body 1 to slide along the sliding guide groove 12 .

[0051] The inkjet printer of this embodiment includes an ink cartridge 9 , and the ink cartridge 9 has a print head 10 .

[0052] Therefore, the print head self-cleaning device of an inkjet printer in this embodiment structurally integrates a scraper, a sealing bin, and a waste ink bin into one, and has the functions of moisturizing, removing dust and preventing dust from the print head, thereby providing conditions for self-cleaning of the print head.

[0053] The design of the self-cleaning device for the print head of an inkjet printer in this embodiment ingeniously utilizes the power of the inkjet carriage to automatically restore the auxiliary spring to the initial position.

[0054] Furthermore, the inkjet printer's print head self-cleaning device of this embodiment can monitor the state of the print head in real time, predict and actively prevent the occurrence of print head blockage by cooperating with the intelligent detection module and the adaptive dynamic maintenance and cleaning control software system. With the maintenance strategy of the control software, on-demand cleaning is achieved, thereby extending the service life of the print head and maintaining stable printing performance.

[0055] Inkjet self-test procedure; ink cartridge maintenance strategy (select medium frequency or high frequency on the right side of the intelligent nozzle anti-clogging); flash spray (pulse jetting for localized and efficient cleaning of blocked nozzles); print cleaning pages and clean the print nozzles at the same time. Keeping the device powered on is also a very effective maintenance behavior.

[0056] Correspondingly, a print head self-cleaning device of an inkjet printer in this embodiment includes an intelligent detection module, a dynamic cleaning module and an adaptive control algorithm unit:

[0057] The intelligent detection module uses a micro sensor to detect the nozzle status;

[0058] The dynamic cleaning module can automatically perform local cleaning operations based on the detection results.

[0059] It can be seen that in existing inkjet printers, print nozzle clogging is a common and important factor that affects print quality. Traditional anti-clogging measures often require manual intervention, which is inefficient and difficult to monitor and handle in real time. The print nozzle self-cleaning device of an inkjet printer in this embodiment is a key module of the intelligent anti-clogging system of the inkjet printer. In conjunction with the intelligent detection module and the adaptive dynamic maintenance and cleaning control software system, it can monitor the status of the nozzle in real time, predict and actively prevent the occurrence of nozzle clogging.

[0060] Therefore, the print head self-cleaning device of an inkjet printer of this embodiment can significantly reduce print quality problems caused by print head blockage, improve work efficiency, reduce maintenance costs, and help improve the technical level of the entire inkjet printing industry.

[0061] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the present invention are included in the scope of the claims of the present invention.
