Waste ink bin

The utility model relates to the field of printers, in particular to a waste ink bin of a printer, which comprises a bottom shell with an inner recess to form a cavity, an upper cover covered on the bottom shell, an ink leakage hole arranged on the upper cover to collect ink, and a first water-absorbent resin arranged at the bottom of the bottom shell to adsorb and lock waste ink. An isolating layer is arranged between the first water-absorbent resin and the upper cover, and the isolating layer can penetrate through the waste ink and block the first water-absorbent resin; the combined waste ink bin can absorb more waste ink, the problem that the waste ink overflows due to excessive ink absorption is avoided, and meanwhile, the resin material is cheap, so that the cost of consumables is lower. 本实用新型涉及打印机领域，尤其涉及打印机的一种废墨仓，包括内部凹陷形成腔室的底壳，底壳上面盖合有上盖，上盖上开有漏墨孔收集墨水，在底壳底部放置有第一吸水树脂以吸附并锁住废墨水，在第一吸水树脂和上盖之间设置有隔离层，隔离层可透过废墨水并阻挡第一吸水树脂；以上组合的废墨仓可以吸附更多的废墨水并且不会出现过度吸墨而溢出废墨水的问题，同时由于树脂材料便宜，耗材的成本更低。
