As shown in fig. 1 to 6, a constant-pressure large-capacity inkjet cartridge includes a cartridge body 1 and a cartridge cover; a film is attached to the box cover; an ink bin, a sponge bin and constant-pressure sponge are arranged in the box body 1, and the box cover comprises a cover body 2 and a pressure regulating unit 3; the cover body 2 is provided with a groove for accommodating the pressure regulating unit 3, and the pressure regulating unit 3 is movably arranged in the groove; the cover body 2 is integrally provided with a pressure regulating cylinder 14, an ink absorbing pipe 13 and a bin cover 15 matched with the sponge bin; the cover body 2 is provided with an air inlet 9, a first ink adding hole 6, a second ink adding hole 11, a first pressure relief hole 7, a diversion trench 4 and a diversion hole 5; the first ink adding hole 6, the first pressure relief hole 7 and the flow guide hole 5 are communicated with the bin cover 15; after the box cover is covered on the box body 1, the bin cover 15 is just clamped on the sponge bin; the ink suction pipe 13 is provided with an ink suction hole 12; the flow guide groove 4 is communicated with the ink absorption hole 12 and the flow guide hole 5;

the pressure regulating unit 3 is provided with an exhaust hole 20, an exhaust groove 19, a second pressure relief hole 16, a third pressure relief hole 17 and a pressure relief groove 21; the exhaust groove 19 is connected with an exhaust hole 20; the pressure relief groove 21 connects the second pressure relief hole 16 and the third pressure relief hole 17; the second pressure relief hole 16 is communicated with the first pressure relief hole 7; a silica gel balloon 18 is fixedly arranged at the bottom of the pressure regulating unit 3, and an exhaust hole 20 is communicated with the silica gel balloon 18; a pressure regulating cavity 10 for accommodating a silica gel balloon 18 is arranged in the pressure regulating cylinder 14, and the silica gel balloon 18 is movably arranged in the pressure regulating cavity 10; the third pressure relief hole 17 is communicated with the pressure regulating cavity 10;

an air inlet groove 8 communicated with an air inlet hole 9 is arranged on the cover body 2.

The working principle is as follows:

ink is added into the ink chamber, when the ink box works, air is fed from the air inlet groove 8 and enters the ink chamber through the air inlet hole 9; ink is sucked into the diversion trench 4 from the ink suction pipe 13 and flows into the sponge bin through the diversion hole 5 for printing; when pressure is generated in the sponge bin, air enters the pressure regulating cavity 10 through the first pressure relief hole 7, the second pressure relief hole 16, the pressure relief groove 21 and the third pressure relief hole 17, the pressure in the pressure regulating cavity 10 is increased, the silica gel balloon 18 is compressed, and the air in the silica gel balloon 18 is discharged to the outside through the exhaust hole 20 and the exhaust groove 19; when the pressure in the sponge bin is recovered, the silica gel balloon 18 recovers the original shape under the self-absorption effect generated when the ink box is used, and constant-pressure adjustment is realized; when the continuous ink supply system is used for connecting an external continuous ink supply system to work, the air inlet holes 9 are used as connecting holes for adding ink to the continuous ink supply box, and continuous and infinite ink supply can be realized.

The design of the invention has the advantages of convenient ink circulation, large ink adding amount at one time, easy ink adding, large printing page number, stable quality, low printing economic cost and environmental protection.
