[0023] The utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0024] Example 1, see Figure 1-5As shown, an electric pizza oven exhaust structure comprises an oven body 1, an air inlet 31 is provided at the bottom of the oven body 1, a chimney 2 is provided at the top of the oven body 1, a cooking cavity 11 is provided in the oven body 1, and the air inlet 31 and the chimney 2 are both connected to the cooking cavity 11. The oven body 1 comprises a bottom shell device 3 and an upper shell device 4, one side of the bottom shell device 3 and one side of the upper shell device 4 are rotatably connected, so that the upper shell device 4 is flipped open relative to the bottom shell device 3, the bottom shell device 3 and the upper shell device 4 surround the cooking cavity 11, the air inlet 31 is provided at the bottom of the oven body 1, and the chimney 2 is provided at the top of the oven body 1. The upper shell device 4 and the bottom shell device 3 are respectively provided with mutually independent heating devices 5, and a detachable cooking utensil 6 is provided at the top of the bottom shell device 3. The cooking utensil 6 can be a pizza stone, a baking tray, a baking net, etc.

[0025] The chimney 2 is provided with an adjusting device 7 for controlling the flue flow of the chimney 2. In this embodiment, the adjusting device 7 includes a cover 8, a bracket 21, a positioning nut 9 and a fixing column 10. A stud 81 with a first screw hole is provided at the center of the bottom of the cover 8, and an upper surrounding wall 82 extends downward from the contour edge of the cover 8. The bracket 21 is arranged inside the top of the chimney 2, and a positioning hole 22 is provided at the center of the bracket 21. The positioning nut 9 is positioned and installed in the positioning hole 22. If the positioning nut 9 is a hexagonal nut, the positioning hole 22 is a hexagonal hole. The fixing column 10 is a bolt, and an external thread is provided on the outer periphery of the fixing column 10. A boss 100 is provided in the middle of the bolt, and the boss 100 divides the external thread into two parts, an upper part and an lower part. The lower part of the fixing column 10 is threadedly connected to the positioning nut 9, the top of the fixing column 10 extends out of the top surface of the chimney 2, and the upper part of the fixing column 10 is threadedly connected to the first screw hole. The bracket 21 is provided with a plurality of through holes 23 around the fixing column 10.

[0026] A lower enclosure wall 24 is provided near the contour edge at the top of the chimney 2, and an upper enclosure wall 82 is placed outside the lower enclosure wall 24. A step 25 is formed between the outer periphery of the lower enclosure wall 24 and the top of the chimney 2. The cover body 8 is rotated to adjust the distance between the cover body 8 and the chimney 2 to control the flue flow rate.

[0027] When cooking, the smoke in the cooking cavity 11 is heated and rises into the chimney 2, passes through the through hole 23 and is discharged from the gap between the cover 8 and the chimney 2. At the same time, the outside air enters the cooking cavity 11 from the air inlet. The user adjusts the cover 8 according to the wind speed and weather in the actual environment, that is, rotates the cover 8 to control the distance between the cover 8 and the chimney 2, so as to control the flow of the flue. Specifically, when the gap between the upper surrounding wall 82 and the step portion 25 expands with the rotation of the cover 8, the flow of the flue gradually increases. When the gap between the upper surrounding wall 82 and the step portion 25 decreases with the rotation of the cover 8, the flow of the flue gradually decreases until the upper surrounding wall 82 and the step portion 25 collide with each other, and the cover 8 closes the flue.
