The continuous ink supply device mainly comprises an ink containing tank 1, an ink box 2, an ink conveying channel 5 and an air guide channel 4 which are connected with each other. The ink containing pool 1 is a closed replaceable part without any channel directly connected with the outside, and can be replaced by a new ink containing pool after the ink is used up; the ink box 2 is a part for connecting the continuous ink supply device with the printer, is also a temporary transfer chamber for supplying ink to the printer, and is provided with an ink supply port 3 for supplying ink to the printer; a continuous supply of ink from the ink reservoir 1 to the ink cartridge 2 is achieved through the ink feed channel 5. The air guide channel 4 and the ink transport channel 5 penetrate through the side wall of the ink containing tank 1 into the ink containing tank 1. The air inlet 41 of the air guide channel 4 is located in the ink cartridge 2 and the air outlet 42 is located in the ink reservoir 1. The ink inlet 51 of the ink channel 5 is located in the ink reservoir 1, and the ink outlet 52 is located in the ink cartridge 2. The upper part of the ink box 2 is provided with an air inlet hole 21, and the air inlet hole 21 leads the ink box 2 to be communicated with the outside atmosphere. In the ink reservoir 1, the air outlet 42 is higher than the ink inlet 51, which mainly prevents ink from flowing from the air guide channel 4 to the ink cartridge 2. In addition, in the ink cartridge 2, the air inlet 41 is higher than the ink outlet 52 because the ink level in the ink cartridge 2 is maintained at the level of the air inlet 41, and if the ink outlet 52 is higher than the air inlet 41, it is communicated with the atmosphere and filled with air. The height of the air inlet 41 is smaller than that of the ink supply port. In addition, the bottom of the ink containing pool 1 is provided with an inclined plate 6, and the inclined plate 6 is lower at the end close to the ink inlet and higher at the end far away from the ink inlet 51. The inclined plate 6 mainly ensures that the ink in the ink containing pool 1 is fully utilized.
When the printer works, as the ink is continuously supplied into the printer through the ink supply port 3, the liquid level of the ink in the ink box 2 drops, when the liquid level of the ink drops below the air inlet 41 of the air guide channel 4, the air inlet 41 of the air guide channel 4 is communicated with the outside atmosphere through the atmosphere air inlet hole 21, the pressure balance state in the ink containing pool 1 is broken, the air enters the ink containing pool 1 along the air guide channel 4, and as the air enters, the ink enters the ink box 2 along the ink conveying channel 5. After the ink tank 2 is supplemented with the ink flowing from the ink containing pool 1, the liquid level rises, when the liquid level rises above the air inlet 41, the atmosphere is not communicated with the ink containing pool 1, the ink containing pool 1 is in a negative pressure state, ink is not supplied to the ink tank 2, and the process is repeated until the air inlet 41 of the air guide channel 4 exposes the ink level next time, so that the ink containing pool 1 is communicated with the atmosphere. The circulation is carried out in such a way that the ink quantity in the ink box 2 is always at a relatively stable value and is generally near the height of the air inlet 41 of the air guide channel 4, so that the ink is supplied to the printer with basically constant pressure.
The structure shows that the ink containing pool of the continuous ink supply device is convenient to place and is not limited by the position of the ink box; the capacity of the ink containing pool can not be limited by the arrangement distance of the ink boxes on the printer and can be increased or reduced according to the actual situation. In addition, because the height of the liquid level in the ink box is basically maintained at the position of the air outlet, a user can adjust the height of the air inlet according to the needs of the user to adjust the ink supply pressure of the ink box to the printer so as to achieve better printing effect.
Example two

The air duct 40 and the ink feed tube 50 extend from the bottom wall of the ink reservoir 10 into the ink reservoir 10. The air inlet 401 of the air duct 40 is located in the ink cartridge 20, and the air outlet 402 is located at the top end of the ink reservoir 10. The ink inlet 501 of the ink channel 50 is located at the bottom of the ink reservoir 10, and the ink outlet 502 is located in the ink cartridge 20. The upper part of the ink box 20 is provided with an atmospheric air inlet hole 201, and the atmospheric air inlet hole 201 enables the ink box 20 to be communicated with the outside atmosphere. In the ink containing pool 10, the air outlet 402 is positioned at the top of the ink containing pool 10 and is higher than the liquid level in the ink containing pool 10, which mainly prevents the air duct 40 from entering the ink; the ink inlet 501 is located at the bottom of the ink reservoir 10 near the bottom wall, so that the ink in the ink reservoir 10 can be fully utilized. In the ink cartridge 20, the air inlet 401 is higher than the ink outlet 502 because the ink level in the ink cartridge 20 is maintained at a level above and below the level of the air inlet 41, and if the ink outlet 502 is higher than the air inlet 401, it is communicated with the atmosphere and filled with air.
Compared with the first embodiment, the air guide channel and the ink conveying channel extend into the ink containing tank from the bottom of the ink containing tank, so that the air outlet of the air guide channel is required to be higher than the liquid level in the ink containing bottle.
