Example implementations can be implemented in any numerous ways, and are not limited to the examples described herein; instead, examples are presented herein for illustrative purposes only and to more fully convey the scope of the application to those skilled in the art. Identical reference numerals can have been used, throughout the specification, to reference like structures; thus, their detailed description can not be repeated here for each structure.

[0035] The terms "a," "an," "the" and "said" are used to refer to one or more than one (i.e., to "at least one") of the referenced items; the term "including" is used to mean "comprising" or "consisting of" and not to preclude additional, unrecited elements; and "consisting of" is used to refer to compositions or processes consisting only of the recited elements.

[0036] The embodiment of the utility model provides a kind of range hood shell, as shown in the drawing, the range hood shell includes shell body 1 and two side plate assemblies 2, two side plate assemblies 2 are symmetrically connected to the two sides of shell body 1, the longitudinal section of shell body 1 is "C" letter shape, shell body 1 includes integrally formed top plate 11, back plate 12 and bottom plate 13, the front end of top plate 11 is bent downward to form mounting plate 14;Wherein, the front end of each side plate assembly 2 is equipped with the connecting structure 200 for being connected with mounting plate 14, and each connecting structure 200 is connected to the outside of mounting plate 14 respectively. Figures 1-7 In the prior art, the top of side plate assembly 2 and the top surface of top plate 11 in the range hood shell that is not integrally connected are rivet connected after alignment, and the process is complex during assembly, and deformation is easily caused between top plate 11 and side plate assembly 2 when the range hood shell falls. The application can effectively improve the connection strength of top plate 11 and side plate assembly 2 by increasing connecting structure 200 on side plate assembly 2 and further connecting and fixing connecting structure 200 above top plate 11, thereby improving the product strength and production efficiency of the entire range hood shell. In the embodiment, top plate 11, back plate 12 and bottom plate 13 are integrally formed, and only side plate assembly 2 needs to be assembled with shell body 1, which realizes the detachability of range hood shell, simplifies the mold structure and improves the material utilization rate; the overall strength is improved by optimizing the structure of side plate assembly 2, especially the connection between side plate assembly 2 and shell body 1 by lap welding.

[0037] In a preferred embodiment of the utility model, as shown in the drawing, Figures 1-4Each side panel assembly 2 shown in Figure 7 includes a side panel 21, a first support plate 22, and a second support plate 23. The side panel 21 is generally trapezoidal and includes a top edge, a front edge, a lower side edge, a bottom edge, and a rear edge connected sequentially. The front edge of the side panel 21 is bent toward the mounting plate 14 to form a first folded edge 211. The first support plate 22 is formed by bending the lower side edge of the side panel 21 toward the mounting plate 14 and is inclined downwards from front to back. The front edge of the first support plate 22 is bent toward the first folded edge 211 to form a second folded edge 221. The second support plate 23 is formed by bending the top edge of the side panel 21 toward the mounting plate 14, and the front edge of the second support plate 23 is bent toward the first folded edge 211 to form a third folded edge 231. The first folded edge 211, the second folded edge 221, and the third folded edge 231 are spliced ​​and welded to form a connecting structure 200. Figure 6 As shown, to facilitate the splicing of the first folded edge 211, the second folded edge 221, and the third folded edge 231, both the second folded edge 221 and the third folded edge 231 are right-angled trapezoids, with the side closest to the side plate 21 being the hypotenuse. The first folded edge 211 includes a trapezoidal segment and a rectangular segment, where the two hypotenuses of the trapezoidal segment correspond to the hypotenuses of the second folded edge 221 and the third folded edge 231, and the rectangular segment corresponds to the short side of the second folded edge 221 and the third folded edge 231. In this way, the first folded edge 211, the second folded edge 221, and the third folded edge 231, after being spliced ​​together, form a larger rectangular plate, which can better match the mounting plate 14 and ensure the appearance of the range hood housing. In addition, by using the first folded edge 211, the second folded edge 221, and the third folded edge 231 formed by the side plate 21, the first support plate 22, and the second support plate 23 respectively, and then welding them together, the structural strength of the side plate assembly 2 can be effectively improved. In other words, this embodiment not only improves the structural strength of the side panel assembly 2, but also increases the connection strength between the side panel assembly 2 and the top plate 11, thereby effectively improving the strength of the range hood housing. It should be noted that the side panel 21 is roughly trapezoidal because the side panel 21 located between the top plate 11, back plate 12, and bottom plate 13 is a trapezoidal structure. To adapt to the structure of the mounting plate 14 and increase the connection strength between the side panel 21 and the top plate 11, an additional edge is added to the side of the side panel 21 near the mounting plate 14, but the overall shape is still similar to a trapezoid. Furthermore, in this application, the directional term "front" refers to the side of the range hood housing closer to the human body, "rear" refers to the side of the range hood housing farther from the human body, and "bottom" refers to the side of the range hood housing farther from the air inlet. These directional terms are for descriptive purposes only and are not intended to limit this application.

After the first folded edge 211 is overlapped and fixed on the step 141, the plane where the top of the first folded edge 211 is located is coplanar with the plane where the top of the top plate 11 is located, so that the appearance requirement of the range hood shell is guaranteed, and through the bolt connection of the first recess 2111 and the step 141, the fixation of the side plate assembly 2 and the mounting plate 14 can be realized, and the quick alignment of the side plate assembly 2 and the mounting plate 14 can be helped, and the production efficiency of the product is improved.

Since most of the existing switch assemblies are square, the reinforcing ribs 144 arranged in the first mounting hole 143 can avoid the problem that the first mounting hole 143 is too long in opening, resulting in the weakening of the strength of the top plate 11. In addition, an avoidance slot is designed at the position corresponding to the reinforcing rib 144 of the switch assembly, and the avoidance slot and the reinforcing rib 144 correspond to each other, which not only realizes the avoidance treatment of the switch assembly to the reinforcing rib 144, but also plays a positioning role when the switch assembly is installed.

[0042] In a preferred embodiment of the utility model, as shown in Figure 1 、 2 and 5, the first flange 142 is provided with a second mounting hole 1421 and a limiting groove 1422 corresponding to the switch assembly. The switch assembly is limited by the limiting groove 1422, and the switch assembly is fastened by the second mounting hole 1421, so that the assembly efficiency of the product can be improved.
