The air box 2 is connected to the smoke hood 1. The top surface of the smoke hood 1 is a weak area and is prone to deformation during transportation and drops. To address this issue, the reinforcing bracket 12 is placed at the connection between the smoke hood 1 and the air box 2, that is, the top of the smoke hood 1 is close to the bottom of the air box 2. Screws pass through the smoke hood 1, and the air box 2 and the reinforcing bracket 12 are connected by screws to increase strength and prevent deformation.
[0041] like Figure 1-7 As shown, in one optional implementation, a lower edge 112 is formed by extending downward along the edge of the air outlet 111. The bottom of the air box 2 and the reinforcing bracket 12 are respectively located on opposite sides of the lower edge 112.

[0044] Based on the aforementioned embodiments, in this embodiment, the top flange 113 is tilted downwards and backwards to contact the reinforcing bracket 12, thereby achieving welding between the reinforcing bracket 12 and the top flange 113 to improve local strength. The liner 13 connects the left and right ends of the outer casing 11, improving overall strength. A pressed shape is formed on the liner 13 to avoid large flat areas, thus increasing the strength of the liner 13. The air inlet plate 14 also connects the left and right ends of the outer casing 11, and a pressed shape is formed on the air inlet plate 14, similarly improving its strength.
[0045] like Figure 1-10 As shown, in one optional implementation, the reinforcing bracket 12 includes a first reinforcing plate 121, a transition plate 122, and a second reinforcing plate 123 connected at an angle in sequence; both the first reinforcing plate 121 and the second reinforcing plate 123 extend in the left-right direction and are both press-formed, the first reinforcing plate 121 is higher than the second reinforcing plate 123, and both the first reinforcing plate 121 and the second reinforcing plate 123 have screw holes, the first reinforcing plate 121 is screwed to the lower edge 112, and the second reinforcing plate 123 is screwed to the liner plate 13.
[0046] Based on the foregoing embodiments, in this embodiment, the reinforcing bracket 12 can be formed from a single sheet of material. The strength of the reinforcing bracket 12 is enhanced by forming the first reinforcing plate 121 and the second reinforcing plate 123 using a pressing method.
[0047] As an optional implementation, the thickness of the first reinforcing plate 121, the transition plate 122, and the second reinforcing plate 123 is greater than or equal to 0.8 mm and less than or equal to 2 mm.

The fixed bracket 17 and the outer shell 11 form a box structure, which improves the local strength and avoids large local movement deformation of the motor assembly 16 during movement, thus preventing abnormal noise.
[0051] like Figure 11 and 12 As shown, in one optional implementation, the first plate 171 is tilted backward from top to bottom.
[0052] Based on the aforementioned embodiments, in this embodiment, the first plate 171 is tilted downward and backward to form an oil guiding structure, and the oil fumes move downward along the first plate 171 to avoid oil stains from accumulating.
[0053] like Figure 11 and 13 As shown, as an optional implementation, the second plate 172 is tilted from top to bottom toward the motor assembly 16.
[0054] Based on the aforementioned embodiments, in this embodiment, the second plate 172 is tilted downward toward the motor assembly 16 to form an air guide structure, thereby improving the performance of the range hood.
[0055] As an optional implementation, the thickness of both the first plate 171 and the second plate 172 is greater than or equal to 0.8 mm and less than or equal to 2 mm.
[0056] By adopting the above technical solution, the strength of the fixed bracket 17 can be guaranteed.

[0058] Based on the aforementioned embodiments, in this embodiment, the smoke hood 1 has a smoke collection chamber inside. An illumination assembly 18 is installed inside the smoke collection chamber. More specifically, the air inlet plate 14 has an illumination lamp mounting port and multiple air inlets communicating with the smoke collection chamber; a rearwardly extending connecting arm 19 is formed on the rear side of the air inlet plate 14, and the illumination lamp mounting port is a rectangular through-hole structure extending along the height direction. The illumination assembly 18 is installed in the smoke hood 1 and located between two air inlets, which can enhance the strength of the middle position of the air inlet plate 14. The illumination assembly 18 extends into the smoke collection chamber to divide the smoke collection chamber into two air ducts, thus preventing the smoke from entering the smoke hood 1 through the air inlets from generating offsetting and turbulent flow, thereby improving smoke exhaust performance and reducing noise.
[0059] The lighting assembly 18 includes a lampshade 181, a lamp 182, and a connector 183. The lampshade 181 has a lamp mounting cavity inside, an opening on its front side corresponding to the lamp mounting port, and a rear side fixedly connected to the housing 11. The lamp 182 is snapped into the opening of the housing 11 and / or the opening of the lampshade 181. The connector 183 is curved and is fitted into the lamp mounting cavity, surrounding the outside of the lamp 182. The connector 183 is screwed to the connecting arm 19 of the air inlet plate 14. Of the rear portion of the lampshade 181 and the back plate 115, the first protrudes towards the second to form a convex portion, and the second is recessed in the opposite direction to the first to form a concave portion. The convex portion inserts into the concave portion to snap the lampshade 181 and the back plate 115 together. Screw holes are provided on both the rear portion of the lampshade 181 and the back plate 115, and screws pass through these holes to achieve a screw connection between the two.
