In order to increase the consumption of users on the ink cartridge, manufacturers of thermal bubble inkjet printers generally make the volume of ink in the ink cartridge smaller, and even further reduce the volume of ink cartridges, which are usually made of sponge and other ink absorbing materials. The ink box structure mostly adopts an integrated ink box which integrates an ink gun with a circuit board and an ink container, the cost of the ink box mainly lies in the ink gun and the circuit board (namely a chip), the service life of the components is longer, and the components can be used for a plurality of times, one ink box can be used for dozens of times or even hundreds of times, namely, dozens of times or even hundreds of times of ink can be added for use. On the other hand, the ink storage cavity of the ink box is small, and ink absorbing materials such as sponge are adopted as ink absorbing carriers, so that ink adding is very inconvenient for users, and after the ink box is used up, only a small amount of ink can be added each time, most of the ink boxes can only add 1 to 2 grams of ink, and the printing nozzle has no ink before ink adding, so that after ink adding, the ink in the sponge needs to be drained to the printing nozzle by means of a tool because the ink is in the ink absorbing materials such as sponge, otherwise, the ink can not be printed, and therefore, the ink drainage is performed under the condition of limited ink adding, and the ink adding of the users is limited in practice.

Therefore, the existing ink box not only has small ink capacity, but also limits the ink adding of users, and the direct discarding of the ink in the ink box after the ink is used can cause the waste of resources and the pollution of the environment.
