[0003] Existing drying ovens have low efficiency, high energy consumption, long drying routes, complex structures and high manufacturing costs.

[0004] A search for "oven and air nozzle and flare" in the Chinese patent disclosure database did not find any relevant literature.

[0005] refer to Fig. 9 The existing design of the air nozzle is an independent component, which requires a lot of processing costs. In addition, the air nozzle in this form does not necessarily distribute the air evenly.

[0006] Searching for "air nozzle and uniform and oven and expansion" in the Chinese patent disclosure database, we found the wind circulation system of the short drying room of the stenter setting machine disclosed in CN108796924A; the double-layer combined drying tunnel disclosed in CN2648364Y; and the double-layer combined drying tunnel disclosed in CN1514196A. They are not directly related to this patent.

[0007] Therefore, a new type of oven structure is urgently needed, which first requires a short distance and secondly requires uniform air distribution. Summary of the invention
