The outer wall around the storage bin 2 is formed with support legs 21, and the support legs 21 contact with the feeding bin 3, so that gaps exist between the periphery of the storage bin 2 and the inner wall of the feeding bin 3, and a channel for flowing of body gas and powder is formed.

The feeding bin 3 comprises a cuboid clamping part 31, a conical funnel-shaped first drainage part 32, a cuboid second drainage part 33, a cylindrical air suction bin 34, a flange connecting pipe 35 and a drainage pipe 36. The holding part 31, the first drainage part 32, the second drainage part 33 and the flange connecting pipe 35 are connected in sequence. The bin cover 1 covers the clamping part 31, and the storage bin 2 is placed in the first drainage part. The air suction bin 34 is positioned outside one side of the second drainage part 33, and the axial direction of the air suction bin 34 is perpendicular to the surface of the second drainage part 33 and is superposed with the central point of the surface of the second drainage part 33. An air inlet interface 341 and an air outlet interface 342 are arranged in the center of the end surface of the air suction bin 34. The gas outlet port 342 is connected with the gas port 13 through a pipeline (not shown).
