[0002] High-speed inkjet printers are devices that use inkjet technology for high-speed printing. They have digital imaging technology and ink delivery systems, and can complete printing tasks quickly and with high quality. High-speed inkjet printers can be used to replace the original small-scale monochrome offset printing machines and large-scale production-type black-and-white electrostatic digital printing machines on the market. They are suitable for printing textbooks, teaching aids, industrial manuals, conference materials, promotional materials and other products. They have the advantages of flexible and changeable printing content, high production capacity, low cost and simple operation.

[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] 1. When in use, the moisturizing sponge absorbs moisture by installing the screen plate, and the moisturizing sponge absorbs moisture when the moisturizing shell is installed, which can continuously provide a moist environment for the inkjet port part of the nozzle body, and can solve the problem that the inkjet port of the current nozzle body is dry after being placed for a long time. When the high-speed inkjet printer is used again, the cleaning function of the printer can also clean the inkjet port more cleanly. The cotton fiber column will expand and elongate when absorbing moisture. The moisture inside the moisturizing shell will evaporate after being placed for a long time. The cotton fiber column will shrink and shorten when the moisture evaporates. Then, the pushing spring will make the reinforcing plate and the fixing rod drive the needle to move, pierce the surface of the liquid bag, and the liquid inside the liquid bag flows out, so that the moisturizing sponge absorbs moisture again. When the moisturizing sponge is not replenished with water in time by humans, the inkjet port can continue to be moisturized. The outer skin of the liquid bag can be reversely hooked by the back-piercing hook, so that the water inside the liquid bag can flow out.
[0019] 2. When in use, the self-test component can detect the moisture content in the air in the area covered by the moisturizing shell. The observation glass window is transparent, allowing the user to intuitively see the color change of the test paper behind the observation glass window. The two ends of the test paper are respectively inserted into the gaps between the first limiting net and the second limiting net and the observation glass window. The test paper uses cobalt oxide test paper, which can be used to detect the presence of water in the air. As the water vapor in the moisturizing shell decreases and the environment gradually becomes dry, the color of the cobalt oxide test paper will gradually change from purple-red back to blue. Therefore, the moisture content of the internal environment of the moisturizing shell can be judged by the color change of the test paper.
[0020] 3. When in use, the moisturizing shell is rotated to cover the inkjet port side of the nozzle body tightly. At this time, the closed outer ring is stuck on the outside of the closed inner ring, and the first sealing ring and the second sealing ring are in close contact, which plays an effective sealing role. It can prevent the moisture inside the moisturizing shell from emitting from the gap between the moisturizing shell and the nozzle body. When tightening the moisturizing shell, the positioning buckle is stuck on the outside of the positioning block to improve the stability of the connection between the moisturizing shell and the nozzle body, and prevent the moisturizing shell from opening automatically.

[0035] In this embodiment, when in use, the interior of the moisturizing shell 201 has a moisturizing effect, the mounting screen 501 is stuck on the right-angle groove inside the moisturizing shell 201, and a plurality of mesh holes are provided on the surface of the mounting screen 501, whose function is to allow moisture to pass through the mesh holes and be absorbed by the moisturizing sponge 502. The moisturizing sponge 502 uses a moisturizing cotton specially used for the inkjet head of a printing machine. When the moisturizing shell 201 is installed, the moisturizing sponge 502 absorbs moisture, and has a good moisturizing effect, and can continuously provide a moist environment for the inkjet port part of the nozzle body 101, and can solve the problem that the current nozzle body 101 is wet for a long time. The inkjet port is dry after being placed for a long time. When the high-speed inkjet printer is used again, the cleaning function of the printer can also clean the inkjet port more cleanly. In addition, the cotton fiber column 402 is made of natural fiber, which will expand and stretch when absorbing water. When the moisturizing shell 201 is first installed, each cotton fiber column 402 absorbs water and is in a state of expansion and elongation. At this time, the elastic force of the push spring 404 is not enough to push the reinforcing plate 403. However, the water inside the moisturizing shell 201 will evaporate after being placed for a long time, so the moisturizing sponge 50 2 and the cotton fiber column 402 will reduce the moisture content, and the cotton fiber column 402 will shrink and shorten when the moisture evaporates, then the push spring 404 will push the reinforcing plate 403 forward to fold the push spring 404, and when the reinforcing plate 403 moves, the fixed rod 406 fixed to the surface thereof will drive the pricking needle 407 to move, and the surface of the liquid bag 503 will be pierced by the pricking needle 407, and the liquid inside the liquid bag 503 will flow out, so that the moisturizing sponge 502 can absorb moisture again, and when the moisturizing sponge 502 is not replenished with moisture in time manually, the inkjet port can continue to be moisturized, By turning over the nozzle body 101 equipped with the moisturizing shell 201, the water flowing out of the liquid bag 503 will be absorbed by the cotton fiber column 402, and the cotton fiber column 402 that has absorbed the water will expand and stretch again, then the fixing rod 406 will start to return to its position, and the back-piercing hook 408 will reversely hook and break the outer skin of the liquid bag 503, so that the water inside the liquid bag 503 will flow out. By using multiple positioning rings 504, the position of the liquid bag 503 when it is not punctured can be prevented from shifting. The skin of the liquid bag 503 is a thin, waterproof plastic skin, which can be used as a water container and is also easy to be punctured to achieve rapid water leakage.
[0036] Embodiment 2: Figure 1-10As shown, installation areas are provided on both sides of the moisturizing shell 201, and a self-test component 3 is fixedly connected inside each installation area, each self-test component 3 includes an observation glass window 301 for observing the moisture changes inside the moisturizing shell 201, and each observation glass window 301 is transparent, the inner bottom surface of each installation area is fixedly connected to a first limiting net 303, the inner top surface of each installation area is fixedly connected to a second limiting net 304, and a test paper 302 for detecting the moisture content inside the moisturizing shell 201 is placed inside each installation area, and each test paper 302 is a cobalt chloride test paper.
[0037] In this embodiment, when in use, the moisture content in the air in the area covered by the moisturizing housing 201 can be detected through the self-test component 3, wherein the specific installation steps are: first, fix the observation glass window 301 on the inner wall of the installation area, the observation glass window 301 is transparent, allowing the user to intuitively see the color change of the test paper 302 behind the observation glass window 301, and in addition, the observation glass window 301 is waterproof, so the moisture inside the moisturizing housing 201 will not be emitted from the observation glass window 301; second, each installation area has a placement space composed of a first limiting net 303 and a second limiting net 304, the mesh structure of the first limiting net 303 and the second limiting net 304 enables it to place the test paper 302 without affecting the circulation of air containing moisture; third, the test paper 302 is fixed to the inner wall of the installation area; The two ends of the paper 302 are respectively inserted into the gap between the first limiting net 303 and the second limiting net 304 and the observation glass window 301. The test paper 302 uses cobalt oxide test paper, which can be used to detect the presence of water in the air. As the water vapor in the moisturizing shell 201 decreases and the environment gradually becomes dry, the color of the cobalt oxide test paper will gradually change from purple-red back to blue, because the cobalt oxide test paper is very sensitive to the moisture content in the environment. When the water vapor inside the moisturizing shell 201 increases, the test paper 302 absorbs moisture and the color changes to purple-red. When the water vapor decreases and the internal environment of the moisturizing shell 201 becomes dry, the test paper 302 loses moisture and the color returns to blue. Therefore, the moisture content of the internal environment of the moisturizing shell 201 can be judged by the color change of the test paper 302.
[0038] Embodiment three: Figure 1-10As shown, the inkjet head main body assembly 1 includes a nozzle body 101, both sides of the nozzle body 101 are fixedly connected with mounting blocks 102, a clamping ring 103 is fixedly connected to one edge of the nozzle body 101, the outer surface of the clamping ring 103 is fixedly connected to a closed inner ring 107 near the inner edge, the outer surface of the clamping ring 103 is fixedly connected to a first sealing ring 104 near the outer edge, the rear surface of the clamping ring 103 is fixedly connected to a connecting main buckle 105, the outer surface of the moisturizing housing 201 is fixedly connected to a second sealing ring 204 near the outer edge of the clamping ring 103, and the outer surface of the moisturizing housing 201 is fixedly connected to the second sealing ring 204 near the second sealing ring 204 A closed outer ring 203 is connected, and the closed inner ring 107 is inserted into the closed outer ring 203. The rear surface of the moisturizing shell 201 is fixedly connected with two connecting side buckles 205, and the two connecting side buckles 205 are respectively located on both sides of the connecting main buckle 105. A latch 106 is slidably connected between the two connecting side buckles 205 and the inner wall of the connecting main buckle 105. The front surface of the moisturizing shell 201 is fixedly connected with a positioning block 206, and the front surface of the retaining ring 103 is fixedly connected with a positioning buckle 108, and the positioning buckle 108 is arranged on the outside of the positioning block 206. A protective cover 202 is fixedly installed on the outer surface of the moisturizing shell 201 away from the moisturizing sponge 502.
[0039] In this embodiment, when in use, first, the moisturizing shell 201 is installed on the inkjet port side of the nozzle body 101. During installation, the main connecting buckle 105 is installed between the two connecting side buckles 205 so that the hole in the middle of the main connecting buckle 105 and the hole in the middle of the two connecting side buckles 205 are in a straight line. Then, the main connecting buckle 105 and the connecting side buckle 205 are connected together by inserting the latch 106 into the inside of the main connecting buckle 105 and the connecting side buckle 205 at the same time, so that the moisturizing shell 201 can be rotatably connected to the nozzle body 101. By rotating the moisturizing shell 201, it can be tightly covered on the inkjet port side of the nozzle body 101. When the moisturizing shell 201 is tightened, the closed outer ring 203 is stuck on the outside of the closed inner ring 107, and the first sealing ring 104 and the second sealing ring 204 are in close contact, which plays an effective sealing role and can prevent the moisture inside the moisturizing shell 201 from emitting from the gap between the moisturizing shell 201 and the nozzle body 101. When tightening the moisturizing shell 201, the positioning buckle 108 is stuck on the outside of the positioning block 206, so as to improve the stability of the connection between the moisturizing shell 201 and the nozzle body 101 and prevent the moisturizing shell 201 from opening automatically. When the moisturizing shell 201 needs to be opened, the positioning buckle 108 is pushed outward to release the engagement with the positioning block 206.
[0040] The method of use and working principle of the device: When in use, first, install the moisturizing shell 201 on the inkjet port side of the nozzle body 101. When installing, install the main connecting buckle 105 between the two connecting side buckles 205 so that the hole in the middle of the main connecting buckle 105 and the hole in the middle of the two connecting side buckles 205 are in a straight line. Then, insert the latch 106 into the inside of the main connecting buckle 105 and the connecting side buckle 205 at the same time to connect the main connecting buckle 105 and the connecting side buckle 205 together, so that the moisturizing shell 201 can be rotatably connected to the nozzle body 101. By rotating the moisturizing shell 201, it can be tightly covered on the inkjet port side of the nozzle body 101. At this time, the closed outer ring 203 is stuck on the outside of the closed inner ring 107 In addition, the first sealing ring 104 and the second sealing ring 204 are in close contact, which can prevent the moisture inside the moisturizing shell 201 from emitting from the gap between the moisturizing shell 201 and the nozzle body 101. When tightening the moisturizing shell 201, the positioning buckle 108 is stuck on the outside of the positioning block 206 to prevent the moisturizing shell 201 from opening automatically. When it is necessary to open the moisturizing shell 201, the positioning buckle 108 is pushed outward to release the engagement with the positioning block 206. When in use, the self-test component 3 can detect the moisture content in the air in the area covered by the moisturizing shell 201. The specific installation steps are: first, fix the observation glass window 301 on the inner wall of the installation area. The observation glass window 301 is transparent, which allows The user can intuitively see the color change of the test paper 302 behind the observation glass window 301. In addition, the observation glass window 301 is waterproof, so the moisture inside the moisturizing shell 201 will not be emitted from the observation glass window 301. Secondly, each installation area has a placement space composed of a first limiting net 303 and a second limiting net 304. The mesh structure of the first limiting net 303 and the second limiting net 304 enables it to place the test paper 302 without affecting the air circulation containing moisture. Thirdly, the two ends of the test paper 302 are respectively inserted into the gap between the first limiting net 303, the second limiting net 304 and the observation glass window 301. The test paper 302 uses cobaltous oxide test paper, which can Used to detect the presence of water in the air, as the water vapor in the moisturizing shell 201 decreases and the environment gradually becomes dry, the color of the cobalt oxide test paper will gradually change from purple-red back to blue, because the cobalt oxide test paper is very sensitive to the moisture content in the environment. When the water vapor inside the moisturizing shell 201 increases, the test paper 302 absorbs moisture and the color changes to purple-red. When the water vapor decreases and the environment inside the moisturizing shell 201 becomes dry, the test paper 302 loses moisture and the color returns to blue. Therefore, the moisture content of the environment inside the moisturizing shell 201 can be judged by the color change of the test paper 302. When in use, the interior of the moisturizing shell 201 has a moisturizing effect. The installation mesh plate 501 is stuck on the right-angle groove inside the moisturizing shell 201.The surface of the installation screen 501 is provided with a plurality of mesh holes, whose function is to allow moisture to pass through the mesh holes and be absorbed by the moisturizing sponge 502. The moisturizing sponge 502 uses a moisturizing cotton specially used for the inkjet head of the printer. When the moisturizing shell 201 is installed, the moisturizing sponge 502 absorbs moisture, and has a good moisturizing effect. It can continuously provide a moist environment for the inkjet port part of the nozzle body 101. When the high-speed inkjet printer is used again, the cleaning function of the printer can also clean the inkjet port more cleanly. In addition, the cotton fiber column 402 is made of natural fiber, which will expand and elongate when absorbing moisture. When the moisturizing shell 201 is first installed, each cotton fiber column 402 has absorbed moisture and is in a state of expansion and elongation. At this time, the elastic force of the pushing spring 404 is not enough to push the reinforcing plate 403. However, the moisture inside the moisturizing shell 201 will evaporate after being placed for a long time. Then the moisturizing sponge 502 and the cotton fiber The moisture contained in the fiber column 402 will be reduced, and the cotton fiber column 402 will shrink and shorten when the moisture evaporates. Then the push spring 404 will push the reinforcing plate 403 forward, so that the push spring 404 will fold. When the reinforcing plate 403 moves, the fixed rod 406 fixed to its surface will drive the thorn needle 407 to move, and the surface of the liquid bag 503 will be pierced by the thorn needle 407, and the liquid inside the liquid bag 503 will flow out, so that the moisturizing sponge 502 will absorb moisture again. When the moisturizing sponge 502 is not replenished with moisture in time, the inkjet port can continue to be moisturized. By turning over the nozzle body 101 equipped with the moisturizing shell 201, the water flowing out of the liquid bag 503 will be absorbed by the cotton fiber column 402, and the cotton fiber column 402 that has absorbed water will expand and stretch again. Then the fixed rod 406 will start to return to its position, and the back thorn hook 408 will reversely hook and pierce the outer skin of the liquid bag 503, so that the water inside the liquid bag 503 will flow out.
[0041] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
