[0007] Furthermore, the atomizing cap is detachably sleeved on the extended powder tube, and the inner wall of the atomizing cap is provided with a buckle which is adapted to a groove provided on the outer wall of the extended powder tube.

[0008] Furthermore, the atomizing cap is spherical in shape.

[0009] Furthermore, the opening on the atomizing cap is in a spiral shape.

[0010] Furthermore, the opening shape of the atomizer cap is an "S" shape.

[0011] Furthermore, the opening on the atomization cap is in a rectangular shape.

[0012] Furthermore, the atomizing cap is conical in shape.

[0013] Furthermore, the length of the extended powder hose is 30-60 mm.

[0014] The above technical solution has the following beneficial effects:

[0015] The atomizing cap of the utility model is designed into various shapes. The powder rotates after entering the powder channel, and the powder enters the atomizing cap through the lengthened powder tube for powder atomization. The shape and opening of each atomizing cap are different. Different atomizing caps can be replaced to meet the coating needs of different complex surfaces. By means of the lengthened powder tube, the length of the nozzle itself is lengthened, and various atomizing caps with different shapes in the figure are switched to cope with complex grooves of the workpiece, solving the problem of no powder being applied to the inner corner of the workpiece during spraying.
