[0022] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0023] Example 1

[0024] The utility model provides a regenerated ink cartridge for an inkjet printer, such as Figures 1 to 6 As shown, it includes an ink cartridge 1, a mounting cover 2 is installed on the top of the ink cartridge 1, a slide groove 3 is provided on the side surface of one end of the ink cartridge 1, and a handle 4 is slidably connected to the inside of the slide groove 3, and a slider 5 is fixedly connected to one end face of the handle 4 inside the ink cartridge 1, and the outer surface of the slider 5 is slidably connected to the center groove block 6, and the outer surface of the center groove block 6 is fixedly connected to the outer surface of the shell 7, and a piston 8 is fixedly installed on one end face of the slider 5. A one-way air outlet cushion 9 is embedded and installed on the end face of the outer side of the shell 7 opposite to the slide groove 3, and an air outlet 10 is provided at the inner center position of the one-way air outlet cushion 9, and the air outlet 10 runs through the center groove block 6, the shell 7 and the one-way air outlet cushion 9. The existing regenerated ink cartridge also includes an ink outlet, a filter port, a sealing gasket and other equipment. The ink inside the ink cartridge 1 is discharged through the ink outlet, and the discharged ink is filtered through the filter port to prevent impurities in the ink from clogging the ink outlet. The above are all existing structures and will not be repeated here.

[0025] like Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, one end face of the slider 5 is fixedly connected to the end opposite to the piston 8 with a positioning spring 11, and the end of the positioning spring 11 away from the slider 5 is fixedly connected to the inner bottom end of the center groove block 6, and the slider 5 is driven by the positioning spring 11 to move in the opposite direction after being pushed, so that the slider 5 can move a second time, thereby making it possible to solve the problem that when air is injected into the ink cartridge 1 once, the ink inside the ink cartridge 1 still cannot be discharged, thereby maintaining the fluidity of the ink inside the ink cartridge 1 and reducing the risk of ink blockage.

[0026] like Figures 3 to 6 As shown, a groove is provided on one end face of the slide groove 3 inside the shell 7, and there are two center groove blocks 6. A connecting rod is fixedly connected to the opposite end faces of the two center groove blocks 6. The outer surface of the connecting rod is movably connected to the torsion spring 15. The surface of the torsion spring 15 is fixedly connected to a baffle 12. The baffle 12 is the same size as the groove. A silicone sealing gasket 13 is installed on the end of the baffle 12 close to the inner wall of the shell 7, and a silicone sealing gasket 2 14 is installed on the end of the inner wall of the shell 7 close to the silicone sealing gasket 13. By installing a one-way air intake device inside the shell 7, when the piston 8 is pushed, air is taken in from the inside of the shell 7 through the one-way air intake device, so that no resistance is generated when the positioning spring 11 drives the piston 8 to move in the reverse direction, thereby avoiding the problem of the air inside the ink cartridge 1 being extracted due to the positioning spring 11 driving the piston 8 to move in the reverse direction.

[0027] like Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, the baffle 12 is rotatably connected to the inside of the shell 7, and the two ends of the torsion spring 15 are respectively located on the inner wall of the shell 7 and the end of the baffle 12 surface opposite to the silicone sealing gasket 13. The torsion spring 15 drives the baffle 12 to block the internal groove of the shell 7, so that when the piston 8 is pushed to move, the baffle 12 will block the internal groove of the shell 7. When the positioning spring 11 drives the piston 8 to move in the opposite direction, air is injected into the center groove block 6 by pushing open the baffle 12, so that when the piston 8 moves in the opposite direction, the air inside the ink cartridge 1 will not be sucked out, thereby making the process of injecting air into the ink cartridge 1 more stable.

[0028] like Figure 2 、 Figure 3 、 Figure 4 and Figure 6 As shown, the slider 5 is the same length as the slide groove 3, and the handle 4 is located at the bottom end of the surface of the slider 5. By pushing the handle 4 to slide inside the slide groove 3, the handle 4 drives the slider 5 to push the piston 8 to inject air into the ink cartridge 1. Since the slide groove 3 is the same length as the slider 5, the slide groove 3 cannot discharge the air squeezed by the piston 8, thereby improving the efficiency of injecting air into the ink cartridge 1.

[0029] like Figures 4 to 6 As shown, the shapes of the slider 5 and the piston 8 are both set to be cylindrical, and the cylindrical piston 8 can form a tight fit with the wall of the center groove block 6, which helps to prevent air leakage during the injection process, and thus makes the process of the piston 8 injecting air into the interior of the ink cartridge 1 more stable, thereby enhancing the airtightness between the center groove block 6 and the piston 8.

[0030] Working principle: The staff puts the recycled ink cartridge 1 on a flat surface and injects ink into the interior of the ink cartridge 1. When the ink injection is completed, the staff installs the ink cartridge 1 on the printer. When the ink inside the ink cartridge 1 cannot be discharged normally, it is because there is residual air inside the ink cartridge 1 or bubbles are introduced when the ink is introduced, which makes the ink inside the ink cartridge 1 unable to be discharged normally. At this time, the staff takes the ink cartridge 1 out of the printer and pulls the handle 4 to move the handle 4. The movement of the handle 4 drives the slider 5 to move. The movement of the slider 5 drives the piston 8 to move. The movement of the piston 8 moves the air inside the circular groove block 6 toward the one-way air outlet cushion 9, and the air inside the one-way air outlet cushion 9 is discharged through the air outlet The opening 10 enters the interior of the ink cartridge 1, so that the air entering the ink cartridge 1 through the air outlet 10 discharges the residual air in the ink cartridge 1 or the bubbles brought in when the ink is introduced through the ink outlet of the ink cartridge 1, thereby completing the process of discharging the residual air in the ink cartridge 1 or the bubbles brought in when the ink is introduced, so that the ink cartridge 1 can discharge ink normally. By installing a piston 8 inside the ink cartridge 1, when the ink inside the ink cartridge 1 is blocked and cannot be discharged, the piston 8 is pushed to inject an appropriate amount of air into the ink cartridge 1, so that the ink cartridge 1 after the air is injected can discharge the internal air, so that the ink inside the ink cartridge 1 after the air is injected can flow normally.

[0031] When the piston 8 moves and completes the injection of air into the ink cartridge 1, the staff presses the baffle 12 through the groove on the surface of the shell 7, so that the baffle 12 applies pressure to the torsion spring 15, and the torsion spring 15 drives the baffle 12 to rotate inside the shell 7. At this time, the baffle 12 rotates inside the shell 7, so that the fitting surface of the baffle 12 and the shell 7 are separated, so that the air enters the center groove block 6 through the gap between the baffle 12 and the shell 7. Then the staff releases the handle 4, and the positioning spring 11 drives the handle 4 to rotate in the opposite direction and reset. At this time, due to the action of the one-way air outlet cushion 9, the ink inside the ink cartridge 1 cannot pass through the one-way air outlet The air cushion 9 is discharged, and finally the staff baffle 12 is released, so that the torsion spring 15 returns to its original shape and drives the baffle 12 to fit together with the outer shell 7. At this time, due to the fit between the outer shell 7 and the baffle 12, the silicone sealing gasket 2 14 and the silicone sealing gasket 1 13 are driven to fit together to seal the gap between the outer shell 7 and the baffle 12, thereby completing the purpose of injecting air into the center groove block 6 when pushing the piston 8 to reset, so that when pushing the piston 8, the interior of the outer shell 7 is aired through the one-way air intake device, so that when the positioning spring 11 drives the piston 8 to move in the opposite direction, no resistance is generated, thereby avoiding the problem of the air inside the ink cartridge 1 being extracted due to the positioning spring 11 driving the piston 8 to move in the opposite direction.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
