Referring to fig. 3 to 13, an ink cartridge 100 provided by an embodiment of the present application includes an ink storage chamber 20, a pressure reducing valve 30, an ink outlet 40, a bottom case 10, and a lead-out chamber 50, wherein:

The ink storage cavity 20, the pressure reducing valve 30 and the leading-out cavity 50 are all arranged in the bottom shell 10, the ink outlet 40 is formed by the bottom wall 12 protruding along the second direction D2, the ink storage cavity 20 is used for storing ink, the ink storage cavity 20, the pressure reducing valve 30 and the ink outlet 40 are mutually communicated, the pressure reducing valve 30 and the ink outlet 40 are communicated through the leading-out cavity 50, the ink storage cavity 20 is located on the upstream side of the pressure reducing valve 30, and the leading-out cavity 50 is located on the downstream side of the pressure reducing valve 30.

The bottom case 10 further includes a first channel 16 and a second channel 17, a recess 18 is provided on the first direction D1 side of the main side wall 15, the ink reservoir 20 is located on the opposite side of the main side wall 15 from the first direction D1, the first channel 16 is for communicating the ink reservoir 20 with the recess 18, and the second channel 17 is for communicating the lead-out chamber 50 with the recess 18.

The ink cartridge 100 supplies ink to the printing apparatus in principle that when the pressure difference (i.e., the downstream pressure) between the lead-out chamber 50 and the pressure reducing valve 30 is smaller than the pressure difference (i.e., the upstream pressure) between the ink reservoir 20 and the pressure reducing valve 30, and the difference between the downstream pressure and the upstream pressure is greater than a preset value, the pressure reducing valve 30 is in an open state, and ink in the ink reservoir 20 can be discharged from the ink outlet 40 via the lead-out chamber 50, thereby supplying ink to the printing apparatus. When the downstream pressure is greater than the upstream pressure or the difference between the downstream pressure and the upstream pressure is smaller than the preset value, the pressure reducing valve 30 is in a closed state, and the ink in the ink storage chamber 20 cannot flow out from the ink outlet 40.

In order to solve this problem, the ink cartridge 100 is usually produced by maintaining the pressure reducing valve 30 in an open state by a special device and then injecting ink into the outlet chamber 50, while the ink cartridge 100 is difficult to implement.

In order to solve the above-described problems, in the embodiment provided by the present application, as shown in fig. 4 and 10, a first valve body 51 is provided in the delivery chamber 50, and a second valve body 171 is provided in the second passage 17. The first valve element 51 is used for controlling the conduction state between the outlet chamber 50 and the ink outlet 40, and when the first valve element 51 moves along the second direction D2, the conduction state between the outlet chamber 50 and the ink outlet 40 can be cut off, and when the first valve element 51 moves along the opposite direction of the second direction D2, the outlet chamber 50 can be communicated with the ink outlet 40.

The second valve member 171 is used to control the conduction state between the recess 18 and the outlet chamber 50, and when the second valve member 171 moves in the third direction D3, the conduction state between the recess 18 and the outlet chamber 50 is cut off, and when the second valve member 171 moves in the opposite direction to the third direction D3, the recess 18 and the outlet chamber 50 are communicated.

The ink cartridge 100 has a filling state and a closing state, when the ink cartridge 100 is in the filling state, the first valve core 51 moves in the opposite direction of the second direction D2 to abut against the second valve core 171, and the second valve core 171 moves in the opposite direction of the third direction D3, the recess 18 is communicated with the lead-out chamber 50, and at this time, the ink can be injected into the lead-out chamber 50 by injecting ink into the recess 18, so that in the state where the ink cartridge 100 just completes replacement, the ink filled in the lead-out chamber 50 can be sucked by the ink supply needle, and then the ink in the ink storage chamber 20 can be continuously replenished into the lead-out chamber 50 by the pressure reducing valve 30 under the action of the pressure difference and sucked by the ink supply needle, thereby being capable of preventing the printer from empty ejection failure. When the ink cartridge 100 is in the closed state, the first valve spool 51 moves in the second direction D2 to shut off communication between the lead-out chamber 50 and the ink outlet 40, and the second valve spool 171 moves in the third direction D3 to shut off communication between the recess 18 and the lead-out chamber 50.

Based on the above embodiment, the ink cartridge 100 of the present application is based on the principle that the ink cartridge 100 is mounted at the mounting position of the printing apparatus, and in the process of supplying ink to the printing apparatus, the first valve core 51 is moved a certain distance along the opposite direction of the second direction D2 and then abuts against the second valve core 171, the first valve core 51 abuts against the second valve core 171 and then can drive the second valve core 171 to move along the opposite direction of the third direction D3, so that the recess 18 is communicated with the outlet chamber 50, and at the same time, the ink is injected into the second channel 17 from the recess 18, so that the ink can be injected into the outlet chamber 50 from the recess 18 through the second channel 17. When the ink cartridge 100 is in the closed state, the first valve core 51 and the second valve core 171 act together to cut off the conduction between the second channel 17 and the discharge chamber 50, and at this time, the ink cannot bypass the pressure reducing valve 30 and be discharged, so that the normal functions of the pressure reducing valve 30 are not affected by the second channel 17 and the second valve core 171, and the ink cartridge 100 is further realized, and the pressure reducing valve 30 is not required to be maintained in the opened state by a special device to fill the ink into the discharge chamber 50 during the ink supplying process, so that the operation is simple.
