[0040] The air inlet groove 11 and the air outlet groove 21 are arranged in a staggered manner; the air inlet guide wall 12 extends towards the second blocking cavity 50, and the air outlet guide wall 22 extends towards the first blocking cavity 40; the channel between the flue inlet 31 and the flue outlet 32 forms an oil fume filter channel 30;

[0041] The air inlet groove 11 and the air outlet groove 21 are strip-shaped groove structures extending in the transverse direction as a whole.

[0042] In the present application, the flue inlets 31 and the flue outlets 32 are arranged in groups and longitudinally spaced apart by being arranged in an up-down staggered manner; each of the air inlet groove 11 and the air outlet groove 21 is in a strip-shaped structure extending in the transverse direction as a whole, so that the transverse span of the oil fume is effectively expanded when the oil fume is fed into the air inlet groove 11, and the effective air inlet area is significantly improved; and when the oil fume is fed into the oil fume filter channel 30 from the flue inlet 31, the oil fume is first fed along the inner side of the air inlet guide wall 12 and then hits the plate surface of the inner oil filter plate 20, and then diffuses around in the second baffle cavity 50, and then hits the outer side of the air outlet guide wall 22 and is guided, flows to the plate surface of the outer oil filter plate 10 and hits again, and then diffuses in the first baffle cavity 40, and finally flows along the inner side of the air outlet guide wall 22 and is fed out from the oil fume outlet, so that the oil fume collides multiple times in the oil fume filter channel 30, and in the diffusion process in the first baffle cavity 40 and the second baffle cavity 50, the flow coverage is large, the wall surfaces of the inner and outer oil filter plates and the guide walls are fully utilized, the effective air inlet area is expanded by the strip-shaped structure extending in the transverse direction, and the oil fume separation effect is significantly improved.

[0043] In the present embodiment, the air inlet groove 11 and the air outlet groove 21 are in a long strip-shaped structure extending in the transverse direction as a whole, which can be a linear strip-shaped groove structure, an arc-shaped strip-shaped groove structure, or a combination of the two.

[0044] In some embodiments, the air inlet groove 11 and the air outlet groove 21 are provided with arc-shaped structures bent downward at both ends. The arc-shaped structures bent downward at both sides can make the oil adsorbed in the first baffle cavity 40 and the second baffle cavity 50 flow smoothly downward along the outer sides of the air inlet guide wall 12 and the air outlet guide wall 22, and then be discharged at the bottom of the oil fume separator.

[0045] In some embodiments, the air inlet groove 11 and the air outlet groove 21 are in an arc-shaped strip-shaped groove structure with the middle part protruding upward and the two ends bent downward. The air inlet groove 11 and the air outlet groove 21 in this arrangement are in an arc-shaped structure extending upward as a whole, so that the oil adsorbed by the oil fume does not accumulate in the middle part of the air inlet guide wall 12 or the air outlet guide wall 22, but flows along the two side downward bending structures, and gradually flows downward in the first baffle cavity 40 or the second baffle cavity 50 to the bottom of the oil fume separator and is discharged.

[0048] In some embodiments, the surface of the inner oil filter plate 20 and the outer oil filter plate 10 is arranged to have a slope, so that the oil on the surface can flow down more smoothly.

[0049] Further, between the adjacent two groups of the flue inlets 31 and the flue outlets 32 arranged longitudinally and spaced apart, a longitudinally extending groove structure is arranged to guide the oil on both sides to flow down and collect, thereby improving the oil fume adsorption and collection capacity.

That is, the top end of the air inlet guide wall 12 and the top end of the air outlet guide wall 22 can be spaced apart by 1 mm to 3 mm, or overlap each other by 1 mm to 3 mm. For example, in the attached Figure 5 , the height span d1 of the two top ends is between 1 mm and 3 mm.

[0053] Further, the outer oil filter plate 10 and the inner oil filter plate 20 can be arranged with limiting grooves and limiting ribs at the bottom or the top, which are adapted to each other and limit each other.

[0054] In the present embodiment, the inner oil filter plate 20 is arranged with an outer frame 23, and the inner oil filter plate 20 and the outer frame 23 form a receiving chamber 60 which is adapted to the shape of the outer oil filter plate. The outer oil filter plate can be detachably installed in the receiving chamber 60. This structure facilitates the assembly of the inner oil filter plate and the outer oil filter plate, and the structure is compact after assembly.

[0056] The existing oil fume separator is provided with vertically staggered fume blocking strips to form an S-shaped oil fume air duct, and the oil fume separation degree is difficult to exceed 98%, and the noise is also high. The oil fume separator of the present application has a noise of only 62 db, the oil fume separation degree can reach 98.1%, and the oil fume suction rate can reach 98.9% when used in a standard static pressure range of a range hood.
