Embodiment 2
[0016] Such as image 3 As shown, for the second embodiment of the high-efficiency range hood, the difference from the first embodiment is that: the filter screen 3 is also circumferentially evenly distributed with protrusions extending from the center of the filter screen 3 to the outer edge of the filter screen 3 The separator strips 33 on the upper and lower surfaces of the filter screen 3 are used to suppress the circumferential movement of the oil on the surface of the filter screen 3 and make the oil move radially outward as much as possible.
[0017] In addition, the inside of the follow-up shaft 32 also has an axial hole 34, and the axial hole 34 extends to the lower end surface of the follow-up shaft 32; while the upper end of the axial hole 34 only extends below the bracket 21, and Connect with the blowpipe 35 that is evenly distributed around the rotating shaft 32; the axis of the blowpipe 35 intersects with the outer edge of the filter screen 3; thus, during the ro...
