When the ink in the free ink chamber 12 is used up, the ink can be injected into the free ink chamber 12 through the ink injection hole 122. So, the printer ink cartridge 1 of this application has realized the used repeatedly after the ink exhausts, has avoided environmental pollution, resources are saved. In addition, since the ink injection device does not directly contact the sponge 113, uneven injection of ink does not occur, resulting in air bubbles, which leads to a reduction in the capacity of the printer cartridge 1.

In the embodiment shown in fig. 1, the vent hole 112 is provided at the top of the sponge chamber 11 with a gap to the sponge 113. Therefore, the sponge cavity 11 can be communicated with the atmospheric pressure, and the sponge 113 can absorb ink after the ink is used up. In other embodiments, the vent 112 may also be located at the side of the sponge cavity 11.

In the embodiment shown in fig. 1, the vent 112 is provided in the housing 100 enclosing the sponge chamber 11, the partition 101 includes a first partition 1011 and a second partition 1012, a vent channel 1013 is formed between the first partition 1011 and the second partition 1012, and the vent channel 1013 connects the vent 112 and the free ink chamber 12. When the sponge 113 absorbs the ink, the air pressure in the free ink chamber 12 is reduced, and air enters the free ink chamber 12 from the ventilation channel 1013. Therefore, the sponge cavity 11 and the free ink cavity 12 can be communicated with the atmospheric pressure at the same time, and after the ink in the sponge 113 in the sponge cavity 11 is used up, the sponge 113 can smoothly absorb the ink stored in the free ink cavity 12.
