[0024] By the above mechanism, when liquid level sensor 10 measures that ink storage under baffle reaches limit value, drive mechanism output will be caused, drive mechanism output makes two extrusion blocks 4 and two push blocks 5 move, extrusion block 4 moves and extrusion is carried out to ink absorption sponge 21, and then ink is supplemented to the below of baffle, while extrusion block 4 and push block 5 move and scrape baffle top and the bottom of ink cartridge body 1 respectively, and then the ink on its surface is passed through filter plate 13 and ink outlet hole, so as to reduce ink residue, and reduce the occupation of storage space, facilitate use.

[0025] As Figure 1 And Figure 3As shown, the driving mechanism comprises first pull ropes 6 respectively mounted on the sides of the two sliders 3, the sides of the ink cartridge body 1 are provided with two first rope holes matched with the first pull ropes 6, the sides of the ink cartridge body 1 are provided with L-shaped plates 7, the inner walls of the bottoms of the L-shaped plates 7 are provided with air cylinders 8, the output ends of the air cylinders 8 are provided with lifting blocks 9, the two first pull ropes 6 are both mounted on the back of the lifting block 9, the sides of the two push blocks 5 are both provided with second pull ropes 10, the sides of the ink cartridge body 1 are provided with two second rope holes, the sides of the ink cartridge body 1 are provided with two limiting rings 11, the other ends of the two second pull ropes 10 are sequentially threaded through the first rope hole and the limiting ring 11 on one side and are mounted on the side of the lifting block 9, and the ink cartridge body 1 is provided with an elastic reset unit. The advantages of such a design are that the first pull ropes 6, the L-shaped plates 7, the air cylinders 8, the lifting blocks 9, the second pull ropes 10 and the limiting rings 11 are arranged to facilitate the mutual approach of the two extrusion blocks 4 and the two push blocks 5.

[0026] Specifically, when the liquid level sensor 10 measures that the ink storage under the partition reaches a limited value, the air cylinder 8 contracts, the contraction of the air cylinder 8 causes the lifting block 9 to move, the movement of the lifting block 9 causes the first pull rope 6 and the second pull rope 10 to be pulled, the force on the first pull rope 6 and the second pull rope 10 causes the extrusion block 4 and the push block 5 to move, the movement of the extrusion block 4 causes the ink absorption sponge 21 to be extruded, thereby supplementing ink under the partition, and at the same time, the movement of the extrusion block 4 and the push block 5 causes the top of the partition and the bottom of the ink cartridge body 1 to be scraped, thereby causing the ink on the surface to pass through the filter plate 13 and the ink outlet hole, thereby reducing ink residue, and at the same time, the air cylinder 8 is arranged outside, thereby reducing the occupation of storage space and facilitating use.

[0027] As shown in Figure 4 The elastic reset unit comprises two fixed grooves respectively provided on the inner walls of the two sides of the ink cartridge body 1, the side inner walls of the four fixed grooves are both provided with first springs 12, and the other ends of the four first springs 12 are both mounted on the sides of the two extrusion blocks 4 and the two push blocks 5. The advantages of such a design are that the first springs 12 are arranged to reset the extrusion blocks 4 and the push blocks 5.

[0028] Specifically, when the lifting block 9 is reset, the first pull rope 6 and the second pull rope 10 will not be pulled, at which time the extrusion block 4 and the push block 5 will be reset under the action of the first spring 12, thereby facilitating use next time.

[0029] As shown in Figure 2 and Figure 5As shown, the fixing mechanism comprises a fixing block 15 mounted on the side of the ink cartridge body 1, a moving cavity is formed on the fixing block 15, a moving plate 16 is arranged in the moving cavity, a trapezoidal block 17 and two pull rods 19 are respectively mounted on the top and bottom of the moving plate 16, a limiting groove and a avoiding hole which are matched with the trapezoidal block 17 are respectively formed on the bottom of the moving block 14 and the top of the fixing block 15, a pulling hole which is matched with the two pull rods 19 is formed on the bottom of the fixing block 15, and a pulling plate 20 is mounted on the bottom of the two pull rods 19. The bottom of the moving plate 16 is provided with an elastic extrusion unit. The advantages of such arrangement are that the filter plate 13 can be replaced conveniently through the arrangement of the fixing block 15, the moving plate 16, the trapezoidal block 17, the pull rod 19 and the pulling plate 20.

[0030] Specifically, when the filter plate 13 needs to be replaced, the pulling plate 20 is pulled first, the pulling plate 20 moves to drive the pull rod 19 to move, the pull rod 19 moves to drive the moving plate 16 to move, the moving plate 16 moves to drive the trapezoidal block 17 to move, the moving block 14 is not fixed when the trapezoidal block 17 moves out of the limiting groove, then the filter plate 13 can be pulled out for replacement, when the new filter plate 13 is inserted into the sliding hole, the moving block 14 is directly extruded, when the moving block 14 contacts with the inclined surface of the trapezoidal block 17, the moving block 14 continues to move to extrude the trapezoidal block 17 to move, the trapezoidal block 17 is reset under the action of the elastic extrusion unit when the trapezoidal block 14 is aligned with the limiting groove, thereby fixing the moving block 14, so that the filter plate 13 can be replaced conveniently, and the use is not affected by the damage caused by long-term use.

[0031] As shown in the Figure 5 The elastic extrusion unit comprises a second spring 18 mounted on the bottom of the moving plate 16, and the other end of the second spring 18 is mounted on the inner wall of the bottom of the moving cavity. The advantages of such arrangement are that the moving plate 16 is quickly reset under the action of the second spring 18 when the moving plate 16 is not forced, thereby quickly fixing the moving block 14.

[0032] As shown in the Figure 1 The bottom inner wall of the ink cartridge body 1 is inclined, which has the advantage of facilitating the flow of ink from both sides to the middle.

[0033] As shown in the Figure 1 The four side outer walls of the two extrusion blocks 4 and the four side outer walls of the two push blocks 5 are all mounted with sealing gaskets, which has the advantage of better scraping the ink when the extrusion blocks 4 and the push blocks 5 move, thereby reducing the residue.

[0034] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, the made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
