The water-flowing plate 120 is installed at the bottom of the chamber body 110, and the bottom of the water-flowing plate 120 is connected to the liquid inlet 5221. There are several water-flowing plates 120, each corresponding to a spray assembly 510. Specifically, the water-flowing plate 120 is funnel-shaped. By setting the funnel-shaped water-flowing plate 120, the cleaning liquid sprayed by each spray assembly 510 in the pretreatment chamber 100 is collected independently and fully converged into the corresponding collection tank 520, preventing the cleaning liquid from mixing between different processes and avoiding cleaning liquid residue in the pretreatment chamber 100.

[0039] During operation, the cleaning conveyor line 200 transports products sequentially through the pre-degreasing mechanism 300, the degreasing mechanism 400, and the rust prevention mechanism 500.
