Therefore, the directional terms used are for explaining and understanding the utility model, rather than for limiting the utility model. In the figure, the units with similar structures are denoted by the same reference numerals.

[0017] The technical scheme and its beneficial effects of the utility model will be made clearer and more definite by further describing the specific embodiments of the utility model in conjunction with the attached drawings.

[0018] Referring to Appendix Figures 1 to 3 , the utility model includes an upper shell 1, a base 2, a filter screen assembly 3 and an air extraction assembly 4 arranged in the upper shell 1. The filter screen assembly 3 is arranged on the left side of the air extraction assembly 4. It is characterized in that: a secondary oil filtering cavity 301 is arranged on the rear side wall of the filter screen assembly 3, and the secondary oil filtering cavity 301 is recessed to the left;

[0019] An air inlet 402 is provided on the front side plate 401 of the exhaust component 4. The diameter of the air inlet 402 is smaller than the outer diameter of the front side plate 401, and the air inlet 402 is located outside the central position of the front side plate 401. The air passing through the filter component 3 forms a turbulent flow in the secondary oil filtering chamber 301 when encountering the front side plate 401. The generation of the turbulent flow increases the contact between this air and the front side plate 401 and the filter component 3, and the remaining oil fumes in the air will adhere to the front side plate 401 and the filter component 3, achieving secondary oil fume filtration.

[0020] Further, a horn-shaped oil guiding part 403 is provided on the air inlet 402, and the oil guiding part 403 tapers from left to right.

[0021] Further, the included angle between the exhaust component 4 and the base 2 is less than 180 degrees and greater than 90 degrees.

[0022] Further, an oil dropping notch 404 is provided at the bottom of the front side plate 401, and the oil dropping notch 404 corresponds to the oil dropping hole 201 on the base 2.

[0023] The accumulated grease in the exhaust component 4 can flow to the oil dropping hole 201 through the oil dropping notch 404.

[0024] Further, a plurality of clamping holes 405 are provided at the edge of the front side plate 401.

[0025] Further, a plurality of connecting pieces 302 that cooperate with the clamping holes 405 are provided at the right edge of the filter component 3, and clamping blocks 303 are provided on the connecting pieces 302.

[0026] The air passing through the filter component 3 forms a turbulent flow in the secondary oil filtering chamber 301 when encountering the front side plate 401. The generation of the turbulent flow increases the contact between this air and the front side plate 401 and the filter component 3, and the oil fumes in the air will adhere to the front side plate 401 and the filter component 3, achieving secondary oil fume filtration. By allowing the air to form a turbulent flow for secondary oil fume filtration, the filtration of the oil fumes in the air can be made more thorough.
