[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 4The utility model provides an embodiment: an inkjet inkjet device with a pressure regulating function, comprising a fixing frame 1, two fixing plates 2 are fixedly connected to the middle of the fixing frame 1, two air pressure pumps 5 are arranged on the rear side of the fixing frame 1, the output end of one air pressure pump 5 is fixedly connected to a positive pressure pipe 10, and the output end of the other air pressure pump 5 is fixedly connected to a negative pressure pipe 11, the middle of the positive pressure pipe 10 and the middle of the negative pressure pipe 11 are both fixedly connected to an electric valve 4, the bottom of the positive pressure pipe 10 and the bottom of the negative pressure pipe 11 are both fixedly connected to a three-way valve 9, the bottom of the three-way valve 9 is fixedly connected to an ink cartridge 8, and the interior of the ink cartridge 8 is fixedly connected to an ink supply port. Tube 6, two sealing rings 15 are provided inside the ink supply tube 6, the inner wall of the ink supply tube 6 is slidably connected with a slider 16, the slider 16 is located between the two sealing rings 15, and the bottom of the slider 16 is fixedly connected with a float 14. A fixing component is provided on the outside of the fixing plate 2, and the fixing component is used to fix the ink cartridge 8. The middle part of the fixing frame 1 is fixedly connected with a controller 3, the bottom of the ink cartridge 8 is fixedly connected with a plurality of ink supply ports 12, the top of the fixing frame 1 is fixedly connected with a switch 7, and the switch 7 is electrically connected to the left electric valve 4. The outside of the ink supply tube 6 is fixedly connected to the top of the fixing frame 1, and the end of the ink supply tube 6 away from the ink cartridge 8 is connected to the ink storage tank.

[0032] Specifically, when the inkjet device is working, the ink inside the ink cartridge 8 will be continuously discharged from the ink supply port 12. When the ink capacity decreases, the float 14 located in the ink will also drop as the ink level drops, and drive the slider 16 located inside the ink supply tube 6 to slide down. Two sealing rings 15 are provided inside the ink supply tube 6 to prevent the slider 16 from sliding out of the ink supply tube 6 and to regulate the ink capacity in the ink cartridge 8. When the slider 16 no longer blocks the hole on the side wall of the ink supply tube 6, ink will be injected from the ink storage tank until the ink level rises, driving the float 14 to float up. After the slider 16 blocks the hole, ink will no longer be poured into the ink cartridge 8. To inject ink, a controller 3 is provided in the middle of the fixing frame 1, which can control the operation of the air pressure pump 5 and the ink delivery port 12. Specifically, the electric valve 4 on the negative pressure tube 11 remains in a normally open state, and the negative pressure tube 11 is connected to the negative pressure pump. At this time, the ink inside the ink cartridge 8 is in a suspended state, allowing the ink to slowly flow through the ink delivery port 12. After pressing the switch 7, the electric valve 4 of the negative pressure tube 11 can be closed and the electric valve 4 on the positive pressure tube 10 can be started. The positive pressure tube 10 is connected to the positive pressure pump. At this time, all the ink in the pipeline and the nozzle can be pressed out, and the ink in the ink cartridge 8 will also be emptied. At this time, the various structures of the inkjet equipment can be cleaned and tested.

[0033] Reference Figure 5The fixed component includes a card box 13, the outer side of the card box 13 is fixedly connected to the side wall of the fixed plate 2, a latch 19 is provided inside the card box 13, the outer side of the latch 19 is sleeved with a spring 17, the middle part of the latch 19 is fixedly connected to the limit plate 20, the top of the card box 13 is slidably connected to the limit rod 18, the bottom of the limit rod 18 abuts against the top of the limit plate 20, the slider 16 is slidably connected to the inside of the card box 13, the outer side of the card box 13 passes through the side wall of the card box 13 and is inserted into the interior of the ink cartridge 8, the right end of the spring 17 is fixedly connected to the left end of the sealing ring 15, the left end of the spring 17 is fixedly connected to the inner wall of the card box 13, and the outer side of the limit plate 20 is slidably connected to the inside of the card box 13.

[0034] Specifically, considering that the ink cartridge 8 is not very firm if it is only placed between the two fixing plates 2, and it is too troublesome to fix it with bolts, this fixing assembly is used to fix the card box 13 to the side of the fixing plate 2, and a hole for the latch 19 to pass through is opened on the fixing plate 2, and a limit rod 18 is slid on the top of the card box 13. The latch 19 can firmly fix the two fixing plates 2 and the ink cartridge 8 together. When the ink cartridge 8 needs to be cleaned, it is only necessary to pull the latch 19 to drive the limit plate 20 to compress the spring 17. When the right end of the latch 19 is directly below the limit rod 18, the limit rod 18 will slide into the card box 13 and press the latch 19. At this time, the ink cartridge 8 can be removed. When installing, it is only necessary to pull the limit rod 18 upwards. Under the action of the spring 17, the latch 19 will be reinserted into the interior of the ink cartridge 8.

[0035] Working principle: The change of ink capacity is detected by the float 14 inside the ink cartridge 8. When the ink water level drops, the float 14 will drop with the water level and drive the slider 16 inside the ink tube 6 to slide down. In the initial position, the slider 16 can block the holes around the ink tube 6. When the slider 16 slides down, the holes are not blocked. At this time, the ink in the ink storage tank is injected into the ink cartridge 8 through the ink tube 6. As the ink is injected, the water level will rise, and the float 14 will float with the water level. The slider 16 will also slide up inside the ink tube 6 and slowly block the holes. At this time, the maximum ink storage volume set by the ink cartridge 8 is reached. Since the negative pressure tube 11 is connected to the low-pressure pump, and the electric valve 4 of the negative pressure tube 11 is always on during operation. Keep it in the open state, so the ink inside the ink cartridge 8 is in a suspended state, and gravity has almost no effect on the ink, which is intended to save ink consumption. After pressing the switch 7, the electric valve 4 located on the positive pressure tube 10 is opened. Since the positive pressure tube 10 is connected to the high-pressure pump, the inside of the ink cartridge 8 will be in a high-pressure state, and the ink inside the ink cartridge 8 will be quickly discharged along the ink supply port 12. When you want to clean the ink cartridge 8, you only need to pull the pin 19. Under the action of the limit plate 20, the spring 17 is compressed, and the limit rod 18 will press the pin 19. At this time, the ink cartridge 8 can be removed. When installing, you only need to place the ink cartridge 8 between the two fixing plates 2, pull the limit rod 18 upwards, and under the action of the spring 17, the pin 19 will finally be inserted into the interior of the ink cartridge 8 to complete the fixation.

[0036] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
