[0027] In the embodiment of the utility model, the stirring blade 7 is in the shape of a beam, and a plurality of stirring rods distributed equally are fixed around the bottom end of the stirring blade 7. The stirring screw 5 can drive the stirring blade 7 and the stirring rod on the left side of the bottom end to perform a circular motion with the stirring screw 5 as a circle to stir the ink in the ink cartridge 1.

[0028] In the embodiment of the utility model, the inner frame of the concentric scraper frame 8 is threadedly connected to the stirring screw 5, and the outer frame of the concentric scraper frame 8 is slidably connected to the ink storage chamber 2. The inner frame and the outer frame of the concentric scraper frame 8 are connected by a fixed rod, which can drive the concentric scraper frame 8 to move downward, allowing the concentric scraper frame 8 to further sweep off the sticky ink on the inner wall of the ink storage chamber 2 to prevent waste.

[0029] In the embodiment of the utility model, the outer surface of the top of the ink cartridge 1 is in the shape of a concave groove with a low middle and high surroundings, which is convenient for workers to grasp the left and right ends of the ink cartridge 1 for disassembly, saving time and effort.

[0030] In the embodiment of the utility model, the visible groove 6 is made of transparent glass, which is convenient for observing the remaining amount of ink in the ink storage chamber 2 and adding ink in time.

[0031] In the embodiment of the utility model, the number of the inlet holes 13 is 8, which are distributed in a left-right symmetrical structure, and the ink seeps evenly from the left and right sides at the same time, preventing the nearby air from being squeezed into the drainage hole 14 and forming bubbles, and affecting the subsequent printing after entering the guide path 15.

[0032] In the embodiment of the utility model, the elastic block 11 is made of elastic and shrinkable material, which facilitates the up and down movement of the ink supply needle 12 and also plays a sealing role.

[0033] Working principle: During the use of the device, the visible groove 6 is used to observe the amount of ink used. When the printer task is turned on, the ink supply needle 12 is pushed up, pierces the elastic block 11, passes through the upper cavity 10, and enters the ink outlet hole 401. The ink seeps down from the introduction hole 13, and enters the diversion path 15 after converging at the drainage hole 14. After the printer task is completed, the ink supply needle 12 is gradually withdrawn, and the remaining ink is stored in the upper cavity 10. The elastic block 11 is naturally reset to prevent the ink from flowing out, and the ink is prevented from seeping out from the ink outlet 4; at the same time, after observing the situation in the ink cartridge 1 through the visible groove 6, the user can rotate the stirring screw 5 according to the situation. The stirring screw 5 can drive the stirring blade 7 and the stirring rod on the left side of the bottom to make a circular motion with the stirring screw 5 as a circle to stir the ink in the ink cartridge 1; at the same time, the rotation of the stirring screw 5 can also drive the concentric scraper frame 8 to move downward, so that the concentric scraper frame 8 can further sweep off the sticky ink on the inner wall of the ink storage cavity 2 to prevent waste.
