The front end of the cleaning box 400 is provided with a sewage flow groove, and the sewage can fall into the inside of the collection frame 210 through the bottom notch of the sewage flow groove. The right side of the sewage flow groove is connected with three sewage grooves, which are respectively connected to the front ends of baffle 1 430, baffle 2 440 and baffle 3 450, so that the sewage can flow to the inside of the collection frame 210 through the sewage flow groove.

[0042] When the water outlet 420 flushes the area above the baffle 1 430 for the second time, the sewage is blocked by the baffle 1 430, and the sewage flows to the sewage circulation groove through the sewage trough. When the water outlet 420 flushes the area above the baffle 2 440 for the third time, the sewage is blocked by the baffle 2 440, and the sewage flows to the sewage circulation groove through the sewage trough. When the water outlet 420 flushes the area above the baffle 3 450 for the fourth time, the sewage is blocked by the baffle 3 450, and the sewage flows to the sewage circulation groove through the sewage trough. Therefore, by flushing the printing roller 110 multiple times, the viscous liquid on the printing roller 110 can be cleaned.
