[0027] To further understand the content, features, and effects of this utility model, the following embodiments are provided, and detailed descriptions are given below in conjunction with the accompanying drawings:

[0028] Firstly, such as Figure 1 , Figure 2 as well as Figure 3 As shown, this utility model provides an oil fume separation mesh, including a first mesh plate 1 and a second mesh plate 2. The first mesh plate 1 and the second mesh plate 2 are detachably fastened together. When the first mesh plate 1 and the second mesh plate 2 are fastened together, an oil fume channel 3 is formed between them, and an opening 4 communicating with the oil fume channel 3 is formed between the first end of the first mesh plate 1 and the first end of the second mesh plate 2.

[0029] In practical applications, the oil fume separation mesh is installed at the air inlet of the range hood body. The range hood body is equipped with an oil removal device, and the oil removal outlet of the oil removal device faces the opening 4. The oil removal device can blow out hot air or hot steam through the oil removal outlet. The hot air or hot steam can enter the oil fume channel 3 through the opening 4, so that the grease adsorbed on the first mesh plate 1 and the second mesh plate 2 can flow down along the oil fume separation mesh under the action of hot air or hot steam, making the oil fume separation mesh clean. This allows for good separation of oil fumes during subsequent use, achieving a good purification rate.

[0030] It should be noted that, with Figure 1 Based on the direction shown, the first end mentioned above refers to the upper end.

[0031] In some preferred embodiments, the second, third, and fourth ends of the first mesh plate 1 each have a first extension plate 11 extending toward the first side, and the three first extension plates 11 form an accommodating space with the first mesh plate 1; the second mesh plate 2 is detachably disposed within the accommodating space. This technical solution facilitates the quick and easy fastening of the second mesh plate 2 and the first mesh plate 1 together.

[0032] It should be noted that, with Figure 1Based on the direction shown, the second end, third end and fourth end mentioned above refer to the left end, the lower end and the right end respectively, and the extension to the first side mentioned above refers to the extension from front to back.

[0033] In some preferred embodiments, the second end and the fourth end of the second mesh plate 2 each have a second extension plate 21 extending towards the second side; or, the second end, the third end, and the fourth end of the second mesh plate 2 each have a second extension plate 21 extending towards the second side. When the second mesh plate 2 is disposed within the accommodating space, the second extension plate 21 abuts against the first mesh plate 1. This technical solution allows the second extension plate 21 to limit the second mesh plate 2 when it is fastened together with the first mesh plate 1, ensuring that a certain distance is formed between the first mesh plate 1 and the second mesh plate 2 to create an oil fume channel 3, thus extending the residence time of oil fumes within the oil fume channel 3 and achieving a better oil fume separation effect.

[0034] It should be noted that, with Figure 1 Based on the direction shown, the aforementioned extension to the second side refers to an extension from back to front.

[0035] In some preferred embodiments, the first end of the first mesh plate 1 has a first connecting portion 12 extending into the opening 4, and the first end of the second mesh plate 2 has a second connecting portion 22 extending into the opening 4. The first connecting portion 12 and the second connecting portion 22 are detachably connected. This technical solution allows the first connecting portion 12 and the second connecting portion 22 to be connected together using screws when the second mesh plate 2 is placed within the accommodating space, thereby achieving the connection and fixation of the first mesh plate 1 and the second mesh plate 2.

[0036] In some preferred embodiments, the first extension plate 11 at the third end of the first mesh plate 1 is provided with an oil drain hole 111. Grease adsorbed on the oil fume separation mesh flows down under the action of hot air or steam and can then flow out through the oil drain hole 111. In specific applications, a detachable oil collecting cup can be installed on the main body of the range hood. When the oil collecting cup is installed on the main body of the range hood, it is located below the oil drain hole 111. Grease flowing out through the oil drain hole 111 can flow into the oil collecting cup for collection. Users can periodically remove the oil collecting cup for cleaning to prevent grease from dripping everywhere.

[0037] It should be noted that when the third end of the second mesh plate 2 has a second extension plate 21 extending to the second side, the second extension plate 21 at the third end of the second mesh plate 2 is provided with a through hole corresponding to the oil leakage hole 111, so that the grease can flow out through the through hole and the oil leakage hole 111 in sequence.

[0038] To ensure smooth flow of grease through the drain hole 111, in some preferred embodiments, the first extension plate 11 at the third end of the first mesh plate 1 has an inclined boss 13, and the drain hole 111 is formed on the inclined boss 13 or located at the bottom end of the inclined boss 13. In practical applications, grease flows down from top to bottom along the first mesh plate 1 and the second mesh plate 2, and under the action of the inclined boss 13, it flows precisely into the drain hole 111 and is smoothly discharged, preventing grease from accumulating on the first extension plate 11 at the third end of the first mesh plate 1.

[0039] In some preferred embodiments, the first mesh plate 1 is provided with multiple rows of first air holes 1a, and the second mesh plate 2 is provided with multiple rows of second air holes 2a. When the first mesh plate 1 and the second mesh plate 2 are fastened together, the first air holes 1a and the second air holes 2a are misaligned. This technical solution allows the oil fumes to form a tortuous path along their travel path, enabling multiple separations of the oil fumes and improving the oil fume separation effect.

[0040] In some preferred embodiments, the edge of the first vent 1a has a third extension plate 5 extending towards a first side, and the edge of the second vent 2a has a third extension plate 5 extending towards a second side. This technical solution increases the contact area between the oil fume and the oil fume separation mesh, thereby further improving the oil fume separation effect.

[0041] Secondly, the present invention provides a range hood, including a main body and an oil removal device, and also includes the oil fume separation mesh mentioned in the first aspect. The oil fume separation mesh is detachably installed at the air inlet of the main body of the range hood. The oil removal device is installed inside the main body of the range hood and has an oil removal outlet facing the opening 4. The oil removal device can blow hot air or spray hot steam into the oil fume channel 3 through the oil removal outlet.

[0042] like Figure 4 As shown, when the oil removal device blows hot air into the fume duct 3 through the oil removal outlet, the aforementioned oil removal device includes a guide element 6 and a heating element 7. Both the guide element 6 and the heating element 7 are located inside the main body of the range hood. The oil removal outlet of the guide element 6 faces the opening 4, and the heating element 7 is located at the air inlet end of the guide element 6 or between the oil removal outlet and the opening 4. After the range hood stops working, the oil removal assembly is activated by the control switch on the main body of the range hood, causing the guide element 6 to blow the hot air heated by the heating element 7 into the fume duct 3 through the opening 4. This causes the grease adsorbed by the fume separation mesh to flow down along the fume separation mesh under the action of the hot air, making the fume separation mesh clean. Specifically, the guide element 6 can be a cross-flow fan, and the air outlet of the cross-flow fan is the oil removal outlet. The heating element 7 can be a heating wire, a heating tube, or a heating plate.

[0043] like Figure 5As shown, when the oil removal device sprays hot steam into the fume duct 3 through the oil removal outlet, the aforementioned oil removal device includes a steam generator 8 and a nozzle 9. Both the steam generator 8 and the nozzle 9 are located inside the range hood body. The water inlet of the steam generator 8 is connected to the water supply device via a pipe, and the steam outlet of the steam generator 8 is connected to the steam inlet of the nozzle 9. The oil removal outlet of the nozzle 9 faces the opening 4. After the range hood stops working, the oil removal assembly is activated by a control switch located on the range hood body. This causes the steam generator 8 to heat the cold water supplied by the water supply device, converting it into hot steam. The hot steam is ejected from the outlet of the nozzle 9 and enters the fume duct 3 through the opening 4. The grease adsorbed on the fume separation screen flows down along the screen under the action of the hot steam, making the screen clean. Specifically, the outlet of the nozzle 9 is the oil removal outlet.

[0044] It should be noted that the water supply device can be an external water tank mounted on the range hood. Preferably, the water in the water tank can be pumped into the steam generator 8 by a water pump.

[0045] In summary, in one or more embodiments of this utility model, the oil fume separation net and range hood of this utility model form an opening between the first end of the first mesh plate and the first end of the second mesh plate, so that the oil removal device of the range hood can blow hot air or spray hot steam into the oil fume channel formed between the first mesh plate and the second mesh plate through the opening. As a result, the grease adsorbed on the oil fume separation net flows down along the oil fume separation net under the action of hot air or hot steam, making the oil fume separation net clean and ensuring that a good purification rate can still be achieved in subsequent use.

[0046] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of this utility model should be included within the scope of the claims of this utility model.
