In the ink cartridge, the air inlet chamber 170 is partially separated from the rear chamber 160, the rest part of the rear chamber 160 is communicated with the front chamber 150 through the ink passage 190, and the front chamber 150, the ink passage 190 and the part of the rear chamber 160 except the air inlet chamber 170 can be used for storing ink, so that the storage capacity of the ink is large, and the utilization rate of the volume in the ink cartridge is high.

In the embodiment, a first ink-absorbing body 200 and a second ink-absorbing body 300 are further included, and the first ink-absorbing body 200 and the second ink-absorbing body 300 are respectively disposed in the first ink-outlet chamber 110 and the second ink-outlet chamber 120. After the first ink absorbing body 200 and the second ink absorbing body 300 absorb ink, the printing device can absorb ink from the first ink absorbing body 200 and the second ink absorbing body 300, and the first ink absorbing body 200 and the second ink absorbing body 300 can prevent the ink from overflowing randomly due to the fact that the ink can be absorbed. In this embodiment, since the ink passage 190 is disposed between the first ink outlet chamber 110 and the second ink outlet chamber 120, the widths of the first ink outlet chamber 110 and the second ink outlet chamber 120 in the left-right direction are smaller, so that the volumes of the first ink absorbing body 200 and the second ink absorbing body 300 can be reduced, which is beneficial to increase the total ink stock.

In an embodiment, the first ink outlet chamber 110 includes a first upper cavity 111 and a first lower cavity 112 arranged up and down, the first upper cavity 111 and the first lower cavity 112 are communicated with each other, the first lower cavity 112 has a first opening disposed downward, the first opening is configured as a first ink outlet 130, two first ink absorbers 200 are disposed and respectively disposed in the first upper cavity 111 and the first lower cavity 112, and of the two first ink absorbers 200, the first ink absorber 200 located on the opposite lower side has a larger adsorption force on ink; the second ink discharging chamber 120 includes a second upper chamber 121 and a second lower chamber 122 arranged up and down, the second upper chamber 121 and the second lower chamber 122 communicate with each other, the second lower chamber 122 has a second opening disposed downward, the second opening is configured as a second ink discharging port 140, two second ink absorbing bodies 300 are disposed and disposed in the second upper chamber 121 and the second lower chamber 122, respectively, and the second ink absorbing body 300 located on the opposite lower side among the two second ink absorbing bodies 300 has a larger adsorption force to ink. With the above-described structure, the first ink absorbing body 200 and the second ink absorbing body 300 on the opposite lower sides have a greater adsorption force for ink, so that the possibility of ink overflowing from the first ink outlet 130 and the second ink outlet 140 can be reduced; the first ink absorbing body 200 and the second ink absorbing body 300 on the opposite upper sides can adopt the ink absorbing body structure with weaker adsorption force, which is beneficial to reducing the material cost of the ink box.

In the embodiment, the first upper chamber 111 and the first lower chamber 112 are separated by a first partition plate, and the first partition plate is provided with through holes communicating with two sides of the first upper chamber 111 and the first lower chamber 112, so that the first upper chamber 111 and the first lower chamber 112 can be communicated with each other, similarly, the second upper chamber 121 and the second lower chamber 122 are separated by a second partition plate, and the second partition plate is also provided with through holes communicating with two sides of the second upper chamber 121 and the second lower chamber 122, so that the second upper chamber 121 and the second lower chamber 122 can be communicated with each other. It will be appreciated that the first upper chamber 111 and the first lower chamber 112, and the second upper chamber 121 and the second lower chamber 122 do not necessarily have to have distinct boundaries (e.g., a divider plate as in the example) as in the previous embodiment, and they may be two portions of one continuous chamber.

In the embodiment, specifically, the first ink absorbing body 200 and the second ink absorbing body 300 are sponges, and the densities of the first ink absorbing body 200 and the second ink absorbing body 300 on the opposite lower sides are relatively large. The first ink absorbing body 200 and the second ink absorbing body 300 are made of sponge, and the cost is low. It is envisioned that in other embodiments, the first ink-absorbing body 200 and the second ink-absorbing body 300 may have other structures, such as porous plastic bodies, etc., as long as they can absorb ink, and those skilled in the art can configure them according to the actual situation.
