[0029] 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 the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0030] Referring to Figures 1-8 , an embodiment provided by the present utility model: An inkjet device includes: a cartridge cover 1 and a cartridge body 2; the cartridge cover 1 and the cartridge body 2 cooperate to form a volume cavity for storing ink; an inkjet component 3 is provided at the bottom end of the cartridge body 2, and the inkjet component 3 is provided with a diversion cavity, which is communicated with the volume cavity, so that the ink is ejected through the inkjet component 3.

[0031] In this embodiment, by forming a volume cavity with the cartridge body 2, the cartridge cover 1 and the inkjet component 3, several first sub-chambers 23 are respectively filled with inks of different colors to store the inks. There is a notch at the bottom of the second partition 22 for circulation. There is a pipeline under the ink absorption structure 5 connected to the nozzle 32 for printing, which stabilizes the flow rate of the ink, so that the ink will not flow out too fast and will not run out of ink.

[0032] A plurality of horizontally arranged first partitions 21 and vertically arranged second partitions 22 are provided inside the cartridge body 2, and a notch is formed at the bottom of the second partition 22, dividing the volume cavity into several first sub-chambers 23 and several second sub-chambers 24 connected to the first sub-chambers 23.

[0033] In this embodiment, two first partitions 21 are provided and one second partition 22 is provided, so that three first sub-chambers 23 and three second sub-chambers 24 are formed inside the cartridge body 2, and the adjacent first sub-chambers 23 and second sub-chambers 24 are communicated, so that the ink flows from the first sub-chamber 23 into the second sub-chamber 24.

[0034] The adjacent first sub - cavity 23 or second sub - cavity 24 is separated by the first partition 21, so that different colors of ink can be stored inside different first sub - cavities 23, and different - colored patterns can be printed as needed.

[0035] A plurality of air vents 11 and a plurality of ink inlets 12 are provided on the cartridge cover 1. The plurality of air vents 11 are located above the plurality of first sub - cavities 23 and communicate with the first sub - cavities 23. The plurality of ink inlets 12 are located above the plurality of second sub - cavities 24 and communicate with the second sub - cavities 24.

[0036] In this embodiment, ink is filled into the inner side of the cartridge body 2 through the ink inlet 12, and the air pressure inside and outside the cartridge body 2 is balanced through the air vents 11. After the ink is filled through the ink inlet 12 on the production line, it is sealed with hot melt adhesive. After the ink is used up or the internal ink expires, the device will recognize the identification code and lock the cartridge body 2 so that it can no longer be used. Locking the cartridge body 2 is controlled on the printing software. The locked cartridge body 2 cannot perform ink - jet work. There is ID information on the cartridge body 2 for external devices to read and write, and it can be replaced as needed. During the printing process, the air inside the cartridge body 2 can also enter through the air vents 11 to balance the internal and external air pressures. A groove 14 is provided on one side of the air vent 11. The groove 14 is designed in an S - shape to allow the ink to flow out smoothly while preventing the ink from flowing out of the cartridge body 2. A connecting block 13 extending upward is provided on the upper end surface of the cartridge cover 1 near the ink inlet 12, and the connecting block 13 is connected to an external device.

[0037] The first sub - cavity 23 extends towards the bottom of the cartridge body 2 and forms a protrusion protruding from the bottom of the cartridge body 2. The ink - jet assembly 3 includes a mounting plate 31 and a nozzle 32. The mounting plate 31 is clamped to the protrusion at the bottom of the cartridge body 2. The nozzle 32 is located between the mounting plate 31 and the cartridge body 2. An ink - absorbing structure 5 is placed inside the first sub - cavity 23, and the material of the ink - absorbing structure 5 is soybean fiber.

[0038] In this embodiment, the mounting plate 31 is clamped to the bottom protrusion of the cartridge body 2. During the ink - jet process, the ink - absorbing structure 5 absorbs ink from the inner side of the second sub - cavity 24, so that the liquid level pressure above the nozzle 32 is stable, and the situation of excessive ink outflow will not occur. At the same time, the ink - absorbing structure 5 blocks the ink outlet at the bottom of the cartridge body 2 to prevent ink leakage caused by unbalanced internal and external pressures due to air intake at the nozzle 32. The material of the ink - absorbing structure 5 is materials such as soybean fiber and sponge, preferably soybean fiber, which stabilizes the ink flow rate so that the ink will not flow out too fast or stop flowing. Secondly, using soybean fiber meets the national standard of GB 4806 - 2023 for food - contact materials, ensuring that food is not contaminated when ink - jetting on food.

[0039] The mounting plate 31 is provided with a hollow structure, and the hollow structure of the mounting plate 31 communicates with the plurality of first sub - cavities 23 to allow the ink to enter the nozzle 32.

[0040] In this embodiment, the mounting plate 31 is designed as a hollow structure, forming three cavities, which are respectively communicated with the three first sub-cavities 23, saving processing materials, reducing weight, and making the structure more stable.

[0041] One side of the box body 2 is provided with a patch contact 4, and the patch contact 4 is electrically connected to the main contact of the external device and the inkjet component 3 to control inkjetting.

[0042] In this embodiment, three nozzles 32 are provided, which are respectively located inside the three cavities of the mounting plate 31 and communicated with the first sub-cavities 23. The corresponding nozzles 32 are controlled to be powered on for inkjetting through the conduction of the patch contact 4 and the main contact of the external device. Among them, the patch contact 4 can also be an induction chip.

[0043] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
