The solenoid valve 4 is mounted on the flexible hose 32, and the second end of the second connecting pipe 33 is used to connect to the negative pressure system of the receiving machine. The solenoid valve 4 is used to control the opening or closing of the negative pressure system of the receiving machine.

[0034] Specifically, during use, the operator first controls the opening of the negative pressure system of the receiving machine through the solenoid valve 4, so that negative pressure is formed in the first connecting pipe 31, the hose 32, and the second connecting pipe 33, thereby forming negative pressure inside the collection box 1 and extracting the gas inside the collection box 1. At this time, under the action of the filter box 21, the paper pieces and paper dust are placed inside the collection box 1.

[0035] This invention places a filter box 21 inside a collection box 1, with filter holes 22 on at least two sides of the filter box 21.
