Specifically, the second top wall 214a is provided with a vent 240, during the operation of filling the ink cartridge 200 with ink, the ink stored in the filling chamber 13 gradually decreases, and when the volume of the ink in the filling chamber 13 decreases, the housing 1 can be deformed to expose the vent 240, so that the air in the ink storage chamber 213 can be discharged from the vent 240, which is beneficial for the ink in the filling chamber 13 to smoothly flow into the ink storage chamber 213; when the ink cartridge 200 is used, the external air can enter the ink storage chamber 213 through the air vent 240, which is favorable for the ink in the ink storage chamber 213 to smoothly flow out from the ink outlet.

Because the housing 1 is deformed to expose the air vent 240, air guide structures such as an air guide groove do not need to be additionally arranged on the second top wall 214a, the structure of the ink cartridge 200 is simplified, the production efficiency of the ink cartridge 200 is improved, and the production cost is reduced.

Further, the first top wall 16a may be provided with a filling opening 14, the filling opening 14 may be detachably provided with the blocking piece 4, when the ink in the filling cavity 13 is exhausted, the filling cavity 13 may be filled with the ink through the filling opening 14, that is, the blocking piece 4 is detached from the filling opening 14, then the ink is filled into the filling cavity 13 from the filling opening 14, and finally the blocking piece 4 is installed at the filling opening 14.

In other embodiments, the cartridge 210 is provided with a plurality of ink storage chambers 213, and the second top wall 214a can be correspondingly provided with a plurality of ink supply portions 220, while the first bottom wall 16b of the filler 100 is provided with only one filling portion 2, the sealing member 3 is provided in the filling portion 2, and the structures of the filling portion 2 and the ink supply portion 220 and the assembly relationship therebetween are the same as those in embodiment 1, and will not be described again.

Specifically, the ink tanks 213 are independent from each other and do not communicate with each other, and when it is necessary to fill one of the ink tanks 213 with ink, the filling portion 2 and the corresponding ink supply portion 220 may be assembled. For example, three ink tanks 213 are provided in the cartridge body 210, the colors of the inks stored in the respective ink tanks 213 are different, and when the three ink tanks 213 need to be filled with the inks, three fillers 100 for storing the inks of the different colors need to be respectively attached to the tops of the ink cartridges 200.

Compared with the prior art, in the ink supply device 1000 provided by the present invention, when the ink cartridge 200 needs to be filled with ink, the filler 100 is installed on the top of the ink cartridge 200, so that the ink supply portion 220 can pierce the elastic opening 32 of the sealing member 3 to be inserted into the ink outlet channel 21, and at this time, the ink cartridge 200 stored in the filling cavity 13 can flow into the ink storage cavity 213 through the ink outlet channel 21 and the ink inlet channel 222; when the operation of filling the ink into the ink cartridge 200 is completed, the filler 100 is detached from the top of the ink cartridge 200, so that the ink supply part 220 is pulled out from the ink outlet channel 21, the elastic opening 32 of the sealing member 3 is closed to close the ink outlet channel 21, thereby avoiding ink leakage caused by the residual or residual ink in the filling cavity 13 possibly flowing out from the filling part 2, and avoiding the ink supply part 220 from contacting with the ink in the ink storage cavity 213, thereby solving the problem that the existing ink filling tool is easy to cause ink leakage to pollute the hand of a user, the ink cartridge 200 and a printer, simplifying the operation of filling the ink, and improving the filling efficiency.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
