Rotary filter screen and range hood

The invention provides a rotary filter screen and a range hood. The rotary filter screen comprises: a first filter screen; and a second filter screen continuously distributed along the edge of the first filter screen and extending in the direction far away from the first filter screen, wherein the first filter screen and the second filter screen are connected in a buckling manner. The second filter screen is continuously distributed along the edge of the first filter screen and extends in the direction away from the first filter screen, so that the rotary filter screen is provided with the first filter screen constructed into the top wall or the bottom wall and the second filter screen constructed into the side wall, and lampblack in multiple directions can collide with the rotary filter screen. For example, oil smoke flowing in the direction perpendicular to the first filter screen can collide with the first filter screen, and oil smoke obliquely flowing relative to the first filter screen and even oil smoke
