In addition, in the sterilization and deodorization process, the air outlet valve plate 332 is utilized to close the air outlet 331, so that ozone gas can be prevented from leaking to the outside of the range hood, and the pollution and damage to the ozone generator 35 caused by the fact that oil smoke in a public flue is leaked into the range hood through the air outlet 331 can be avoided.
Still further, in this embodiment, a first rotating shaft 3322 is fixed at the upper end of the air outlet valve plate 332 and is rotatably connected to the air inlet 3331 through the first rotating shaft 3322, a second rotating shaft 383 is fixed at one end of the air outlet valve plate 38 and is rotatably connected to the air outlet 381 through the second rotating shaft 383, and a motor 3323 for driving the first rotating shaft 3322 to rotate is disposed at one end of the first rotating shaft 3322. A connecting rod 36 is disposed between the air outlet valve plate 332 and the air outlet valve plate 38, a first pivot seat 3324 and a second pivot seat 384 are disposed at corresponding positions of the air outlet valve plate 332 and the air outlet valve plate 38, and two ends of the connecting rod 36 are connected with the first pivot seat 3324 and the second pivot seat 384. Thus, when the air outlet valve plate 38 rotates relative to the air outlet 381, the air outlet valve plate 332 can rotate between the air outlet 331 and the air inlet 3331, when the air outlet valve plate 332 closes the air outlet 331, the air outlet valve plate 38 leaves the air outlet 381, while the air inlet 3331 opens, and when the air outlet valve plate 332 leaves the air outlet 331 and closes the air inlet 3331, the air outlet valve plate 38 closes the air outlet 381. An air outlet groove 382 extending to the vertical side wall 333 is formed on the inner bottom surface of the purifying cavity 34, the air outlet 381 is formed in the air outlet groove 382, the air outlet valve plate 38 is matched with the air outlet groove 382, the second rotating shaft 383 is rotatably connected to one end of the air outlet groove 382 adjacent to the vertical side wall 333, when the air outlet 331 is closed by the air outlet valve plate 332 and the air outlet 381 is opened, the air outlet valve plate 38 is limited on the air inlet 3331, and in this embodiment, the air outlet valve plate 38 is clamped in the air inlet 3331. Since the air outlet 381 is generally required to be connected with the air outlet pipe, the air outlet 381 is generally circular, and the air outlet cover 311 is generally square, so the air inlet 3331 is also generally square, so that the air outlet 331 and the air inlet 3331 can be smoothly closed by the air outlet valve plate 332 at the same time, and good tightness can be obtained when the air outlet 331 is closed, and a circular boss 3321 matched with the air outlet 331 is arranged on the surface of the air outlet valve plate 332 facing the air outlet 331.

The air outlet valve plate 332 is opposite to the air outlet valve plate 38, and is fixed between the two by a connecting rod 36, and a first rotating shaft 3322 is fixed at the upper end of the air outlet valve plate 332 and is rotatably connected in the air inlet 3331 by the first rotating shaft 3322. When the air outlet valve plate 332 and the air outlet valve plate 38 are rotated to the vertical positions, the air outlet valve plate 332 closes the air inlet 3331, and the air outlet valve plate 38 closes the air outlet 381. When the air outlet valve plate 332 and the air outlet valve plate 38 are rotated to the horizontal positions, the air outlet valve plate 332 closes the air outlet 331, while the air outlet valve plate 38 is positioned in the air outlet chamber 33, and the air inlet 3331 and the air outlet 381 are simultaneously opened.
