[0045] Example 1

[0046] Please refer to Figure 1-Figure 7The present invention provides a range hood comprising a smoke hood 2, a front smoke baffle structure 3, and side smoke baffle structures 4. The smoke hood 2 defines a smoke collection chamber with a smoke inlet at its lower side. One end of the front smoke baffle structure 3 is movably connected to the front end of the smoke hood 2 for opening and closing the smoke inlet. The side smoke shield structure 4 includes a mounting assembly, a rotating shaft assembly and a first side wing plate 41. The mounting assembly is installed in the smoke collecting chamber. The first side wing plate 41 is rotatably connected to the mounting assembly through the rotating shaft assembly. The first side wing plate 41 is installed on the left and / or right side of the smoke collecting hood 2 and is located on the rear side of the front smoke shield structure 3. When the front smoke shield structure 3 opens the smoke inlet, the first side wing plate 41 extends downward from the smoke collecting chamber under the action of gravity. When the front smoke shield structure 3 closes the smoke inlet, the front smoke shield structure 3 pushes the first side wing plate 41 to rotate relative to the mounting assembly and retract it into the smoke collecting chamber. In this way, on the one hand, when the front smoke shield structure 3 opens the smoke inlet, the first side wing plate 41 can also extend out of the smoke collecting chamber under the action of gravity to achieve the collection of smoke, without the need for power to push the first side wing plate 41 to unfold. On the other hand, when the front smoke baffle structure 3 closes the smoke inlet, the front smoke baffle structure 3 can push the first side wing panel 41 into the smoke collecting chamber, thereby storing the first side wing panel 41 in the smoke collecting chamber, achieving a better hiding effect, and making the appearance of the range hood more beautiful when in standby state.

[0047] Optionally, the shaft assembly includes a first shaft 431 and a second shaft 432.
