When the ink cartridge is used, when the ink in the ink cartridge 1 is sufficient, the first buoyancy block 10 floats on the ink, the support rod 9 connected with one end of the rotating shaft 8 is in the vertical direction through the generated buoyancy, and the deflector rod 11 fixed at the other end of the rotating shaft 8 is in the horizontal state; after the printing machine is used for a period of time, ink in the ink box 1 is less and less, the supporting rod 9 rotates towards the horizontal direction when the height of the first buoyancy block 10 is reduced along with the ink liquid level, the free end of the deflector rod 11 is tilted through the rotating shaft 8, and the T-shaped rod 7 can be pushed to move upwards in the sleeve 20; along with the reduction of the ink amount, the T-shaped rod 7 moves upwards to be in contact with the oil pump 4, the oil pump 4 is triggered to start, the oil pump 4 pumps out the ink in the ink storage tank 2 through the oil inlet pipe 5 and puts the ink into the transfer tank 3 through the oil outlet pipe 6;

before the ink enters the transfer tank 3, the liquid level of the ink in the transfer tank 3 is lower than the inlet of the siphon tube 19 and is not enough to trigger the siphon effect of the siphon tube 19, the second buoyancy block 23 and the filter basket 16 are arranged at the bottom of the transfer tank 3, and the opening of the filter basket 16 faces upwards; when the ink in the oil outlet pipe 6 enters the transfer tank 3, the ink can fall downwards into the filter basket 16, impurities in the ink are left in the filter basket 16, and the filtered ink enters the transfer tank 3; the ink flowing out of the oil outlet pipe 6 can wash the filter screen of the filter basket 16, so that impurities are prevented from blocking the filter screen; when the liquid level in the transfer pool 3 rises, the second buoyancy block 23 moves upwards through the sliding of the T-shaped block 22 in the T-shaped groove 21; the second buoyancy block 23 drives the filter basket 16 to move upwards, when the filter basket 16 reaches the wedge block 15 between the two rectangular plates 14, the upper end of the filter basket 16 is in contact with the inclined surface of the wedge block 15, the filter basket 16 can continuously move upwards to push the front wedge block 15 and the rear wedge block 15 to respectively move towards two sides through the inclined surfaces, the two wedge blocks 15 respectively enter the blind holes 25 on the corresponding sides through compressing the pressure spring 26, the filter basket 16 can upwards pass through the two wedge blocks 15 and continuously move upwards, and the wedge block 15 moves towards the middle under the reset action of the pressure spring 26 to reset; the liquid level of the ink in the transfer pool 3 is higher and higher until the siphon tube 19 is triggered to generate siphon effect, and the ink in the transfer pool 3 is sucked into the ink box 1 through the siphon tube 19;

ink flows into the ink box 1 through the siphon tube 19, the liquid level in the ink box 1 begins to rise, the first buoyancy block 10 floats, the support rod 9 rotates in the vertical direction and drives the deflector rod 11 to rotate in the horizontal direction through the rotating shaft 8, when the liquid level in the ink box 1 begins to rise, the T-shaped rod 7 loses the support of the deflector rod 11, the T-shaped rod 7 moves downwards in the sleeve 20, the upper end of the T-shaped rod 7 is separated from the switch of the oil pump 4, and the oil pump 4 is closed and does not continue to pump out the ink;

after the ink remained in the oil outlet pipe 6 flows out of the transfer pool 3, no ink is supplemented into the transfer pool 3, the ink in the transfer pool 3 flows into the ink box 1 through the siphon pipe 19, the liquid level of the ink in the transfer pool 3 drops, and the filter basket 16 moves downwards along with the second buoyancy block 23; in the process that the siphon tube 19 sucks the ink in the transfer pool 3 into the ink box 1, the descending speed of the ink liquid level in the transfer pool 3 is high, the filter basket 16 moves downwards to the upper end face of the wedge block 15 and is blocked by the wedge block 15, impact can be formed on the wedge block 15, the filter basket 16 rotates rightwards under the blocking action of the wedge block 15, the opening of the filter basket 16 inclines downwards and is in contact with the first blocking rod 17 to form impact, and filter residues are poured into the filter residue recovery box 13 through the through groove 12; the filtering basket 16 rotates rightwards and moves downwards along with the second buoyancy block 23, the filtering basket 16 can press the second stop rod 18 downwards when continuing to move downwards to the second stop rod 18, the generated reaction force can enable the filtering basket 16 to rotate leftwards and reset, and the filtering basket 16 and the second buoyancy block 23 continue to move downwards and reset along with the descending of the liquid level;

along with the ink in the transfer pool 3 flowing into the ink box 1 through the siphon tube 19, the liquid level in the ink box 1 rises, the support rod 9 is reset to the vertical position under the buoyancy action of the first buoyancy block 10 until the liquid level of the ink in the transfer pool 3 is lower than the inlet of the siphon tube 19, and at the moment, the ink in the ink box 1 is sufficient and is enough for the printer to use for a period of time; when the ink in the ink box 1 is insufficient, the T-shaped rod 7 can move upwards to trigger the oil pump 4, so that the ink is automatically added when the ink is insufficient, and circulation is formed in sequence.

The ink box 1 adopts the first buoyancy block 10, the rotating shaft 8 rotates forwards by utilizing the liquid level to drive the deflector rod 11 to rotate upwards, the deflector rod 11 pushes the T-shaped rod 7 to move upwards to reach the switching position of the oil pump 4, and the oil pump 4 is triggered to start ink adding; compared with a sensor, the mechanical structure has the advantages of ink corrosion resistance and difficult damage, and is suitable for photosensitive ink.
