DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following further describes the present application in detail with reference to the drawings. It is necessary to point out here that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the protection scope of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application according to the above application content.

[0022] Refer to the attached instructions Figures 1-6 Figures 1-6 , an oil mesh component for a range hood, includes an outer oil mesh 31 and an inner oil mesh 32 installed on the front side of the outer oil mesh 31. A positioning hole 311 is opened at the upper end of the outer oil mesh 31, and a support hole 321 is provided at the upper end of the inner oil mesh 32. A marble 33 is arranged inside the support hole 321, and the upper end of the marble 33 is snapped into the positioning hole 311; a protrusion 312 is provided at the bottom edge inside the outer oil mesh 31, and the bottom of the inner oil mesh 32 is inserted at the rear side of the protrusion 312, so that the protrusion 312 blocks the bottom of the inner oil mesh 32.

[0023] It should be noted that during installation, first insert the bottom of the inner oil mesh 32 inside the bottom of the outer oil mesh 31, and block the bottom of the inner oil mesh 32 through the protrusion 312 to prevent it from slipping out. Then, push the upper end of the inner oil mesh 32 into the inside of the outer oil mesh 31, so that the marble 33 is snapped into the positioning hole 311, thereby realizing the installation of the inner oil mesh 32. During disassembly, pull the inner oil mesh 32 outwards to move the marble 33 out of the positioning hole 311 (when the marble 33 is snapped into and out of the positioning hole 311, the upper end of the outer oil mesh 31 undergoes a slight deformation), and then pull the bottom end of the inner oil mesh 32 upwards to remove it from the outer oil mesh 31. By adopting the above technical solution, screwless installation of the inner oil mesh 32 can be achieved, making both installation and disassembly relatively convenient.

[0024] Furthermore, as Figure 5 shown, the upper end of the marble 33 has a spherical surface 331.

[0025] It should be noted that the spherical surface 331 is beneficial for the marble 33 to be snapped into and out of the positioning hole 311.

[0026] Furthermore, as Figure 2 shown, a groove 310 is provided at the front side position of the upper end of the outer oil mesh 31. The groove 310 has a structure with an opening at the front side. A plate hole 320 is provided at the front side position of the upper end of the inner oil mesh 32. Both the front side and the rear side of the plate hole 320 are open structures. The groove 310 and the plate hole 320 are arranged opposite to each other, and the opening structure of the groove 310 is larger than that of the plate hole 320.

[0027] It should be noted that the opening structure of the groove 310 is larger than that of the plate hole 320, that is, the length and / or width of the groove 310 is greater than that of the plate hole 320, so that when disassembling the inner oil mesh 32 from the outer oil mesh 31, the hand can reach into the groove 310 through the plate hole 320, and then the hand can pull the edge of the plate hole 320 to disassemble the inner oil mesh 32 from the outer oil mesh 31. Through the arrangement of the groove 310 and the plate hole 320, when disassembling the inner oil mesh 32, the hand can apply force better, achieving the purpose of labor saving.

[0028] Refer to the attached instructionsFigures 1-3 , a plurality of vertically arranged outer oil baffle plates 3101 are provided on the outer oil screen 31, and a plurality of vertically arranged inner oil baffle plates 3201 are provided on the inner oil screen 32. Both ends of the outer oil baffle plate 3101 are bent towards the inner oil screen 32, and both ends of the inner oil baffle plate 3201 are bent towards the inner oil screen 32 of the outer oil screen 31. A first air duct 301 is formed between adjacent inner oil baffle plates 3201, and a second air duct 302 is formed between the ends of adjacent outer oil baffle plates 3101 and inner oil baffle plates 3201.

[0029] Furthermore, an oil baffle strip 3103 is provided between adjacent outer oil baffle plates 3101, and a third air duct 303 is formed between the oil baffle strip 3103 and the adjacent outer oil baffle plate 3101.

[0030] Still further, an outer convex strip 3102 is provided in the middle of the side of the outer oil baffle plate 3101 close to the inner oil screen 32, and an inner convex strip 3202 is provided in the middle of the side of the inner oil baffle plate 3201 close to the outer oil screen 31.

[0031] It should be noted that when the range hood is working, the oil fume is successively drawn away from the first air duct 301, the second air duct 302 and the third air duct 303. By bending both ends of the outer oil baffle plate 3101 and the inner oil baffle plate 3201, it is beneficial to form the second air duct 302. When the oil fume is flowing, it can collide with the outer oil baffle plate 3101, the inner oil baffle plate 3201, the outer convex strip 3102, the inner convex strip 3202 and the oil baffle strip 3103 in the first air duct 301, the second air duct 302 and the third air duct 303, so that the oil and gas molecules adhere to the outer oil screen 31 and the inner oil screen 32, achieving the purpose of oil fume separation.

[0032] The above embodiments only represent several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
