As shown in the figure, the ink cartridge 1 further comprises a flow guide member 5 installed in the ink outlet portion 4 and a filter member 6 installed on the flow guide member 5, wherein the flow guide member 5 is used for guiding the ink in the ink outlet portion 4, and the flow direction of the ink in the ink outlet portion 4 is changed to ensure that the ink discharged from the ink outlet portion 4 can pass through the filter member 6, and even if the ink discharged from the ink outlet portion 4 has lumps, the filter member 6 can filter out the lumps; specifically, the guide 5 blocks or seals the guide groove 44 so that the ink is no longer discharged through the guide groove 44.
The flow guide member 5 comprises a main body 51 and an acting part 53 connected with the main body 51, wherein the main body 51 is used for fixing the flow guide member 5 on the box body 2, and the acting part 53 is used for blocking or sealing the flow guide groove 44 so as to change the flow direction of the ink in the flow guide groove 44. Preferably, the main body 51 is a cylinder having an ink flow path 52, the acting portion 53 is a protrusion extending outward from the circumferential surface of the main body 51, when the guide member 5 is installed, the main body 51 enters the ink outlet chamber 40, the protrusion 53 enters the guide groove 44, and thus, the ink in the ink outlet chamber 40 cannot be discharged from the guide groove 44, and is guided to the ink flow path 52 provided on the main body 51, and generally, the ink flow path 52 is a through hole penetrating the main body 51 in the ink discharge direction, the through hole is concentrically arranged with the cylindrical ink outlet chamber 40, and the outer surface of the main body 51 is closely fitted with the inner surface of the ink outlet chamber 40, and accordingly, the protrusion 53 is also closely fitted with the guide groove 44, and finally, the ink in the ink outlet chamber 40 can be discharged only through the through hole 52.
Further, the flow guide member 5 further includes a support block 54 axially extending from the main body 51 in the ink flow direction, when the flow guide member 5 is mounted, the support block 54 is configured to abut against the bottom plate 41, so that the position of the flow guide member 5 in the ink flow direction in the ink outlet chamber 40 is defined, and at the same time, the support block 54 also enables a small storage space to be formed between the through hole 52 and the bottom plate 41, and the ink in the chamber 20 first enters the storage space from the communication port 42 and then is discharged through the through hole 52, so that the continuity of ink discharge is ensured. In the embodiment of the invention, the filter element 6 can be selected from common sponge or a filter screen, when the filter element 6 is the filter screen, the flow guide element 5 is also provided with a welding line, and the filter element 6 is welded on the flow guide element 5, so that the ink discharged through the through hole 52 can pass through the filter screen 6, and the agglomeration in the ink is filtered by the filter screen 6; as shown in fig. 7, when the ink flows through the ink outlet chamber 40, the cross section of the ink flow path is the cross section of the through hole 52, and in the regeneration, it is only necessary to ensure that the cross section of the through hole 52 is circular or other regular shape, and the filter 6 can completely cover the ink flow path.
The position of the guide member 5 for welding the filter member 6 is closer to the chamber 20 than the ink outlet 43 in the direction of flow of ink in the ink outlet chamber, and when the ink cartridge 1 to which the filter screen 6 is welded is mounted to an ink jet printer, an ink suction needle in the ink jet printer enters the ink outlet chamber 40 through the ink outlet 43, but the ink suction needle does not touch the filter screen 6, and therefore, the integrity of the filter screen 6 is ensured.
As another embodiment, the structure of the flow guiding member 5 can also be simplified, for example, the main body 51 of the flow guiding member 5 is not limited by contacting with the inner wall of the ink outlet chamber 40, the main body 51 of the flow guiding member 5 is fixed at another position inside the ink outlet 4 or at a certain position outside the ink outlet 4, and it can be realized that the main body 51 is clamped at the circumferential edge of the ink outlet 43 by clamping, or fixed at the outer surface of the ink outlet 4 by snapping/magnetic attraction, etc.; meanwhile, the projection 53 is still connected to the main body 51, and the projection 53 blocks the guide groove 44, at this time, the main body 51 is not in contact with the ink outlet chamber 40, that is, the radial dimension of the ink outlet chamber 40 is not reduced, the ink discharge amount per unit time is larger, and of course, the filter 6 is still installed on the flow path of the ink in the ink outlet chamber 40.
In addition, the diversion member 5 can be simplified to only have the projection 53 for blocking the diversion trench 44, and as in the above embodiment, the projection 53 is still tightly matched with the diversion trench 44, and the ink is completely guided to the ink outlet cavity 40 to be discharged; the protrusion 53 can be regarded as a main body having a positioning function and a function portion connected to the main body, and it can be understood that a portion of the protrusion 53 not contacting with the inner wall of the guide groove 44 can be regarded as the main body and a portion contacting with the inner wall of the guide groove 44 can be regarded as the function portion.
Alternatively, the guide member 5 may be a sealing member for sealing an outlet of the guide groove, which is an outlet located at the end of the guide groove in the discharge direction of the ink in the ink discharge chamber 40, and when the outlet of the guide groove is sealed, the ink is guided to be discharged entirely through the ink discharge chamber 40.
