Obviously, the embodiments described in the utility model are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of the utility model.

[0020] like Figure 1-4 As shown, the powder material nozzle device includes a special-shaped elbow 1, a guide pipe 2 and a blowing pipe 3. The first end 21 of the special-shaped elbow 1 is connected to the guide pipe 2, and the second end 12 is connected to the blowing pipe 3. The first end 21 and the second end 12 are arranged opposite to each other; the third end 11 is used to connect to the powder spray tank; the first end 21 is used to connect to the guide pipe 2, and the second end 12 is used to connect to the blowing pipe 3.

[0021] like Figure 2As shown, the axis of the third end 11 of the special-shaped elbow 1 is perpendicular to the axes of the first end 21 and the second end 12; the diameter of the port of the third end 11 is larger than the diameter of the port of the first end 21, and the port of the third end 11 and the port of the first end 21 are connected through an arc tube; an opening is opened at the bending position of the arc tube at a position opposite to the port of the first end 21, which serves as the third end 11.

[0022] like Figure 3 As shown, one end of the guide pipe 2 is welded to the port of the first end 21, and a flange 22 is welded to the second end of the guide pipe 2; the third end 11 is welded to the mounting pipe 4, the mounting pipe 4 is processed with an internal thread, and the blow pipe 3 is processed with a section of external thread 31, and a pagoda joint 32 is provided at one end adjacent to the external thread 31, the blow pipe 3 is inserted into the mounting pipe 4, and the external thread 31 is matched with the internal thread of the mounting pipe 4, and the insertion of the blow pipe 3 at one end of the mounting pipe 4 extends to the first end of the special-shaped elbow; the second end of the blow pipe 3 is exposed outside the mounting pipe 4, and is used to connect with an air hose through the pagoda joint 32, and the air hose is used to connect with an external gas conveying device to input high-pressure air.
