DETAILED DESCRIPTION

[0020] The utility model is further explained in connection with the drawings and specific embodiment.

[0021] like Figure 1 As shown, a high-efficiency grease filter for a fume hood includes: a first end filter 1, a second end filter 2, an intermediate filter 3, a first connecting edge 4, and a second connecting edge 5.

[0022] like Figure 3 As shown, there are several intermediate filter sheets 3, which are arranged between the first end filter sheet 1 and the second end filter sheet 2, and the filter sheets are parallel to each other. The first connecting edge 4 and the second connecting edge 5 are respectively connected to the two ends of each filter sheet to form a rectangular structure.

[0023] Among them, such as Figure 4 As shown, the main body of the intermediate filter 3 has a right-angled Z-shaped structure, with a first inclined part 6 and a second inclined part 7 respectively provided at both ends.

[0024] The first inclined portion 6 slopes downward from the top of the intermediate filter 3, and the second inclined portion 7 slopes upward from the bottom of the intermediate filter 3. Both the first inclined portion 6 and the second inclined portion 7 extend outward from the intermediate filter 3, and are parallel to each other. An L-shaped connecting portion 8 is connected to the other end of the second inclined portion 7 to form a U-shaped structure. The side of the L-shaped connecting portion 8 that connects to the second inclined portion 7 is perpendicular to the second inclined portion 7, making the other side of the L-shaped connecting portion 8 parallel to the second inclined portion 7.

[0025] Preferably, the L-shaped connecting part 8 is provided with a serrated structure 10 at its end to increase the friction of the oil fume separation zone, thereby improving the separation effect.

[0026] Each intermediate filter 2 is interlocked with the others, such that the U-shaped structure of one intermediate filter 2 is located below the structure formed by the top horizontal part and the first inclined part 6 of the adjacent intermediate filter 2, so as to form a bent air duct.

[0027] The first end filter 1 is L-shaped, with a first inclined portion 6 and a first horizontal portion 9 respectively provided at both ends. The first inclined portion 6 is the same as the first inclined portion 6 of the middle filter 2. The first horizontal portion 9 extends from the bottom of the first end filter 1 in the direction of the middle filter 3, and is spaced from the middle filter 2 to form an air duct.

[0028] The second end filter 2 is in the shape of a U-shape, with one end connected to the second horizontal part 12. The second horizontal part 12 extends from the bottom of the second end filter 2 toward the middle filter 3, and its end is provided with an L-shaped connecting part 8, forming a U-shaped structure similar to the middle filter 3. This U-shaped structure is located below the middle filter 2 adjacent to the second end filter 2 to form an air duct and separation area.

[0029] like Figure 2 As shown, a number of openings 11 are provided on the second connecting edge 5, and each opening 11 is provided in correspondence with each U-shaped structure so that the grease in the core separation zone can be discharged through the opening 11.

[0030] Working principle: as Figure 5 shown, the adjacent two intermediate filter 2 form air duct, a first inclined portion 6 of intermediate filter 2 and the main body vertical portion of adjacent intermediate filter 2 form air inlet, the first inclined portion 6 is made into air inlet flow guide structure, the inclined structure makes airflow in the movement be forced along the set path, in order to achieve the predetermined separation effect; when the airflow enters the air duct, first with the bottom corner structure of intermediate filter 2, according to Bernoulli principle, when the high speed airflow passes through the side, a relatively low pressure zone is generated, the low pressure has adsorption effect, can adsorb part of oil smoke at the collision and form vortex along the inner wall structure, under the impact of continuous vortex, oil smoke particles will be thrown to the inner wall to realize separation, this is the first auxiliary classification area;

[0031] The airflow continues to advance, and the main body of the intermediate filter 2 and the second inclined portion 7 form a second auxiliary classification area, the principle is the same as the first auxiliary classification area;

[0032] After passing through the second auxiliary classification area, the airflow enters the V-shaped structure, when the airflow flows along the V-shaped structure, the structure is located at the edge of the main airflow, and the relative state is a low pressure state, which has adsorption effect, and can adsorb most of the finer oil to the inside of the V-shaped structure, the semi-closed structure of the V-shaped structure will promote the airflow to drive the oil particles to rotate inside continuously, realizing continuous separation, which is the core separation area;

[0033] After passing through the core separation area, the airflow will pass through the main body of the adjacent intermediate filter 2 and the first inclined portion 6 connection and the top corner of the adjacent intermediate filter 2, respectively, which are the third and fourth auxiliary classification areas;

[0034] Finally, after the core oil smoke separation and multi-stage auxiliary separation filtering effect, clean airflow is discharged from the air outlet formed by the second inclined portion 7 and the main body of the intermediate filter 2.
