A plurality of discharge holes 8 are evenly distributed around the atomizing nozzle 6, and a trumpet-shaped discharge hole is arranged at the lower end of the atomizing nozzle 6. The diffuser 7 is arranged in the middle of the trumpet-shaped discharge hole, and an annular gap is arranged between the conical surface of the diffuser 7 and the inner wall of the trumpet-shaped discharge hole. High-pressure materials are sprayed out from the multiple discharge holes of the atomizing nozzle, and at the same time, the materials are further dispersed by means of the conical surface of the diffuser to achieve the purpose of material atomization.

[0024] In another specific embodiment of the present invention, Figure 3As shown, the atomization structure includes an inverted cone nozzle 9, a material mixing ring 10 and a conical nozzle 11, the inverted cone nozzle 9 is arranged at the lower end outlet of the feed pipe 4, the large diameter end of the inverted cone nozzle 9 is connected to the outer circle of the material mixing ring 10 through an outer cone 12, the small diameter end of the inverted cone nozzle 9 is connected to the inner circle edge of the material mixing ring 10 through an inner cone 13, and a guide channel 14 is provided between the outer cone 12 and the inner cone 13; a plurality of discharge holes 8 communicating with the guide channel 14 are evenly distributed on the inverted cone surface of the inverted cone nozzle 9, and the top feed hole of the material mixing ring 10 is communicated with the guide channel 14; the conical nozzle 11 is arranged in the inner cavity of the inner cone 13, and a center hole 15 communicating with the feed pipe 4 and the top feed port of the conical nozzle 11 is provided in the middle of the inverted cone nozzle 9, and the opening of the conical nozzle 11 is arranged downward. After the high-pressure material is divided through the discharge hole and the center hole in the inverted cone nozzle, the peripheral material flows along the guide channel to the material mixing ring and is sprayed out from the material mixing ring; the other part of the material flowing out of the center hole is sprayed through the conical nozzle, thereby achieving the purpose of atomizing the material.
