The feeding mechanism includes a powder container 3, a pressure column 4, and a feeding assembly. The powder container 3 has a chamber for accommodating powder, which can be filled into the chamber. The pressure column 4 is disposed below the powder container 3 and has a through hole 41 extending vertically, which communicates with the chamber of the powder container 3. The through hole 41 of the pressure column 4 is provided with a cover that can be opened and closed. In the initial state, the cover is placed inside the through hole 41, and the through hole 41 always tends to be closed. Specifically, the cover includes a cover body 42 rotatably disposed in the through hole 41 and an elastic member 43 abutting between the cover body 42 and the through hole 41. The elastic member 43 ensures that the cover body 42 always tends to block the passage between the through hole 42 and the chamber, preventing the passage of powder. The feeding assembly is disposed on the powder container 3 and includes a drive member (not shown in the figure, the drive member includes but is not limited to a drive motor) and a feeding member 5 connected to the drive member. The feeding member 5 is movably disposed directly above the through hole 41 and controlled by the drive member. The feeding member 5 can drive the cover body 42 on the through hole 41 to flip downward, thereby opening the through hole 41 and allowing the powder to pass through.

[0044] Furthermore, the maximum outer diameter of the feeder 5 is less than or equal to the diameter of the through hole 41, so that the feeder 5 can pass through the pressure column 4. The feeder 5 has an initial state located above the through hole 41 and a feeding state with its lower end inserted into the through hole 41.
