The other end of the positioning rod 3031 is fixed to the baffle 3021. The outer side of the positioning rod 3031 is sleeved with a tension spring 3032, and the two ends of the tension spring 3032 are fixedly connected to the side of the sleeve rod 303 and the baffle 3021 respectively. When in use, through the provided filling bin 3, when adding ink, the sealing plate 302 is opened by pulling the pull rod 3022, thereby opening the filling bin 3. After the ink is added, the tension spring 3032 will drive the sealing plate 302 to reset through its own tension, thereby realizing the sealing of the filling bin 3, which is convenient and quick.

[0026] Furthermore, a snap ring 101 is fixedly connected to the top of the side of the box body 1, and slide grooves 102 are provided at both ends of the inner wall of the box body 1. A scale 103 is fixedly connected to both ends of the box body 1. A through hole is provided in the middle of the lower surface of the box body 1, and a filter plate 104 is fixedly connected to the through hole on the lower surface of the box body 1. When in use, the slider 501 inside the slide groove 102 can be observed from the outside through the provided scale 103, which is cast from acrylic transparent material, thereby realizing observation of the remainder inside the box body 1.

[0027] Furthermore, at the outer ring of the lower surface of the cover plate 2, there are rectangular blocks 201 arranged at equal intervals, and the inner walls of the blocks 201 are fixedly engaged with the clamping ring 101. A mounting groove is provided in the middle of the upper surface of the cover plate 2, and a filter screen 202 is fixedly connected to the mounting groove in the middle of the upper surface of the cover plate 2. When in use, the filter screen 202 can filter the added ink, thereby preventing impurities in the ink from entering the interior of the box body 1 and clogging the ink inlet pipe of the printer, thereby improving the stability of the device.

[0028] Furthermore, the inner wall of the ink outlet tube 4 is provided with a limiting groove 401 in an annular shape and at equal intervals, and the inner wall of the ink outlet tube 4 is provided with a limiting rod 402, the top end of the limiting rod 402 extends to the upper surface of the filter plate 104 and is fixedly connected to the mounting plate 403, the lower surface of the mounting plate 403 is fixedly connected to the sealing gasket 4031, the lower surface of the sealing gasket 4031 is adapted to the upper surface of the filter plate 104, the bottom end of the limiting rod 402 is fixedly connected to the limiting plate 404, and the side surface of the limiting plate 404 is arranged in an annular shape with limiting arms 4041 at equal intervals, and the side surfaces of the limiting arms 4041 are all slidably connected to the inner wall of the limiting groove 401, and the outer side of the limiting rod 402 is provided with an elastic spring 405, the top end of the elastic spring 405 is against the lower surface of the filter plate 104, and the elastic spring 405 is The bottom end is against the upper surface of the limit plate 404. During use and installation, the interface of the printer will push the limit arm 4041 to move upward. When it moves, it will drive the limit rod 402 to move upward through the limit plate 404. The limit rod 402 will push the mounting plate 403, so that the mounting plate 403 drives the sealing gasket 4031 to move away from the surface of the filter plate 104. At this time, the ink inside the cartridge body 1 will flow into the interior of the printer through the ink outlet pipe 4, thereby realizing the installation of the device. At the same time, during disassembly, the elastic spring 405 will push the limit plate 404 to return to its original position through its own elastic force, so that it drives the mounting plate 403 and the sealing gasket 4031 to fit the surface of the filter plate 104, thereby realizing the blocking of the ink outlet pipe 4, thereby improving the sealing of the device.

[0029] Furthermore, both ends of the floating plate 5 are fixedly connected with sliders 501, and the outer sides of the sliders 501 are slidably connected to the inner walls of the slide groove 102. The lower surface of the floating plate 5 is linearly and equidistantly arranged with floats 502. When in use, the floats 502 will generate buoyancy in the ink inside the box body 1, thereby driving the floating plate 5 to move. When the floating plate 5 moves, it will drive the slider 501 to move, thereby realizing the observation of the remaining ink inside the box body 1.

[0030] The working principle of the present invention is as follows: when in use, the device is first installed in the installation slot of the printer. During this process, the interface of the printer will push the limit arm 4041 to move it upward. When it moves, it will drive the limit rod 402 to move upward through the limit plate 404. The limit rod 402 will push the mounting plate 403, so that the mounting plate 403 drives the sealing gasket 4031 to move away from the surface of the filter plate 104. At this time, the ink inside the cartridge body 1 will flow into the interior of the printer through the ink outlet pipe 4, thereby realizing the installation of the device. At the same time, when disassembling, the elastic spring 405 will push the limit plate 404 back to its original position through its own elastic force, so that it drives the mounting plate 403 and the sealing gasket 4031 to fit the surface of the filter plate 104, thereby realizing the blocking of the ink outlet pipe 4, thereby improving the sealing performance of the device.

[0031] During use, the float 502 generates buoyancy in the ink inside the cartridge 1, thereby driving the float plate 5 to move. When the float plate 5 moves, the slider 501 moves. The scale 103 is made of transparent acrylic material, and the position of the slider 501 inside the chute 102 can be observed from the outside, thereby realizing the observation of the remaining amount inside the cartridge 1, which is conducive to improving the flexibility of the device.

[0032] When ink needs to be added, first pull the pull rod 3022 to open the sealing plate 302, thereby opening the filling bin 3. After the ink is added, the tension spring 3032 will drive the sealing plate 302 to reset through its own tension, thereby achieving sealing of the filling bin 3, which is convenient and quick, and is conducive to further improving the flexibility of the device.
