[0042] Example 1

[0043] Combination Figures 1 to 8 As shown, this utility model provides an oil mesh structure, which includes: a front oil mesh 10, which is provided with a plurality of first guide strips 110 arranged separately, and an air inlet 101 is formed between two adjacent first guide strips 110; the front side of the first guide strip 110 is provided with a windward surface, and the windward surface is provided with a rearwardly recessed windward groove 1101, the length direction of the windward groove 1101 is the same as the length direction of the first guide strip 110;

[0044] The rear oil screen 30 is provided with multiple separated second guide strips 310, and an air outlet 301 is formed between two adjacent second guide strips 310; the middle oil screen 20 is located between the front oil screen 10 and the rear oil screen 30, and the middle oil screen 20 is provided with multiple separated intermediate diversion strips 210, and the intermediate diversion strips 210 are provided corresponding to the air inlet 101 and the air outlet 301.

[0045] Specifically, the oil mesh structure of this application comprises a front oil mesh 10, a middle oil mesh 20, and a rear oil mesh 30. When installed on a range hood, the fan inside the range hood generates airflow, drawing the fumes from the front of the range hood into the range hood through the oil mesh structure. During the process of passing through the oil mesh, the fumes are separated into smoke and oil droplets. The oil droplets condense on the front side and inside of the oil mesh structure and slide down into a waste oil tank or waste oil box under their own gravity, while the smoke enters the range hood and is eventually discharged, thus achieving oil-fume separation.

[0046] In this process, a portion of the fumes located in front of the range hood first come into contact with the air intake sill 1101. Since the air intake sill 1101 is recessed, this increases the contact time between the fumes and the air intake sill 1101, allowing more fumes to condense and adhere to it, thus enhancing the fume separation effect. Another portion of the fumes enters the oil filter structure through the air inlet 101. Under the action of the middle diversion strip 210 of the middle oil filter 20 and the second guide strip 310 of the rear oil filter 30, the contact time between the fumes and the middle and rear oil filters is increased, achieving fume separation and thus improving the fume separation effect.

[0047] Compared with the prior art, this application innovatively provides a rearwardly recessed windward groove 1101 on the front side of the front oil mesh 10, so that before the oil fumes enter the oil mesh structure, part of the oil fumes will first come into contact with the windward groove 1101 and condense into oil droplets in the windward groove 1101, while the other part of the oil fumes will enter the oil mesh structure through the air inlet 101, and achieve oil fume separation under the action of the middle diversion strip 210 of the middle oil mesh 20 and the second guide strip 310 of the rear oil mesh 30, thereby improving the oil fume separation effect.

[0048] In this embodiment, the groove depth of the windward groove 1101 is 10-15 mm.

[0049] In this embodiment, the first guide strip 110 includes a windward section 1102 and two first guide sections 1103. The two first guide sections 1103 are respectively disposed at the left and right ends of the windward section 1102, so that the cross-section of the first guide strip 110 is U-shaped. Specifically, the windward section 1102 is provided with a windward groove 1101. Some of the oil fumes will first come into contact with the windward groove 1101 on the windward section 1102, and then be split into two airflows, which then enter the interior of the oil mesh structure through the air inlet 101 along the first guide sections 1103. The cross-section of the first guide strip 110 is U-shaped, rather than a complex irregular structure, which facilitates processing and production.

[0050] In this embodiment, the second guide strip 310 includes an air collecting section 3101 and two second guide sections 3102. The two second guide sections 3102 are respectively disposed at the left and right ends of the air collecting section 3101 to form a rear oil collecting trough 3103, making the cross-section of the second guide strip 310 "U" shaped. When the oil fumes inside the oil mesh structure need to leave through the air outlet 301, the oil fumes will first contact the rear oil collecting trough 3103 and condense on it, while some of the fumes will flow along the second guide sections 3102. This embodiment utilizes the "U" shaped rear oil collecting trough 3103 to further separate the oil fumes, increasing the contact area between the oil fumes and the oil mesh structure, thereby improving the oil fume separation effect; moreover, the cross-section of the second guide strip 310 is "U" shaped, rather than a complex irregular structure, which facilitates processing and production.

[0051] In this embodiment, the intermediate diversion strip 210 includes an intermediate separation section 2101 and two intermediate guide sections 2102. The two intermediate guide sections 2102 are respectively disposed at the left and right ends of the intermediate separation section 2101. The front and rear ends of the two intermediate guide sections 2102 are respectively provided with extensions, so that the cross-section of the intermediate diversion strip 210 is "H" shaped. Among them, the front extensions of the two intermediate guide sections 2102 and the front side of the intermediate separation section 2101 form an intermediate front oil collection groove 2103, and the rear extensions of the two intermediate guide sections 2102 and the rear side of the intermediate separation section 2101 form an intermediate rear oil collection groove 2104.

[0052] Specifically, the intermediate diversion strip 210 of this application has a unique "H"-shaped structure. When the front oil screen 10, the middle oil screen 20, and the rear oil screen 30 are used together, the oil fumes undergo the first oil-fume separation in the windward groove 1101 of the front oil screen 10. The oil fumes enter the interior of the oil screen structure through the air inlet 101. Since the intermediate diversion strip 210 is set corresponding to the air inlet 101, the oil fumes will flow to the intermediate front oil collection groove under the guiding action of the first guide section 1103. 2103, the intermediate front oil collection tank 2103 performs a second oil fume separation. The separated oil fume flows along the intermediate guide section 2102 to the rear oil collection tank 3103, where it performs a third oil fume separation. The separated oil fume flows along the second guide section 3102 to the intermediate rear oil collection tank 2104, where it performs a final oil fume separation and is discharged to the air outlet 301. This embodiment improves the oil fume separation effect through multiple oil fume separations.

[0053] In this embodiment, a receiving opening 102 is provided on the rear side of the front oil mesh 10, and the receiving opening 102 is used to house the middle oil mesh 20 and the rear oil mesh 30. This embodiment utilizes the receiving opening 102 to house and package the middle oil mesh 20 and the rear oil mesh 30, saving installation space and making the overall oil mesh structure thinner. Furthermore, the middle oil mesh 20 and the rear oil mesh 30 are detachable from the front oil mesh 10, facilitating disassembly and cleaning.

[0054] Furthermore, the front oil mesh 10 is provided with mounting holes on its side, and the middle oil mesh 20 and the rear oil mesh 30 are provided with locking blocks designed corresponding to the mounting holes on their sides. The locking blocks are used to cooperate with the mounting holes to install the middle oil mesh 20 and the rear oil mesh 30 into the receiving port 102.

[0055] Example 2

[0056] This embodiment also provides a range hood, which includes: a range hood body 40; a barrier net 50 disposed on the range hood body; the barrier net 50 is provided with a plurality of spaced barrier strips 510, and the barrier strips 510 are provided with oil guide grooves 5101, the oil guide grooves 5101 being arranged facing forward; the oil mesh structure described above is disposed on the range hood body and located in front of the barrier net 50, and the air outlet 301 is disposed corresponding to the oil guide grooves 5101.

[0057] Specifically, to prevent the interior of the range hood from being exposed after the oil filter structure is removed, this application installs a barrier net 50 on the range hood to prevent users from putting their hands inside. Furthermore, the multiple barrier strips 510 form multiple barrier openings, which, without affecting the airflow generated by the fan, also allow the oil guide grooves 5101 on the barrier strips 510 to perform final separation of oil fumes, further improving the oil fume separation effect.

[0058] Furthermore, the oil droplets condensed on the oil mesh structure and the barrier mesh 50 will slide down into the waste oil tank or waste oil box for collecting oil under their own gravity.

[0059] Furthermore, the oil guide groove 5101 is recessed rearward to form an oil guide arc surface, so as to increase the contact area between the oil guide groove 5101 and the oil fume, and to better separate the oil fume.

[0060] Example 3

[0061] This embodiment is basically the same as Embodiment 2, except that the oil mesh structure of the range hood in this embodiment can use other oil mesh structures in the art. Specifically, this embodiment also provides a range hood, which includes: a range hood body; a barrier mesh 50 disposed on the range hood body; the barrier mesh 50 is provided with a plurality of spaced barrier strips 510, and the barrier strips 510 are provided with oil guide grooves 5101, the oil guide grooves 5101 being arranged facing forward; an oil mesh structure disposed on the range hood body and located in front of the barrier mesh 50, the air outlet 301 of the oil mesh structure being arranged corresponding to the oil guide grooves 5101.

[0062] Furthermore, the oil guide groove 5101 is recessed rearward to form an oil guide arc surface, so as to increase the contact area between the oil guide groove 5101 and the oil fume, and to better separate the oil fume.
