[Specific implementation method]

[0029] In order to make the purpose, scheme and beneficial effects of the present application more clear, the present application is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0030] See also Figure 1 A range hood decorative cover mounting structure includes an exterior cover 2 and an interior cover 1. The exterior cover 2 is located at the periphery of a fan bracket 3 of the range hood. The lower end of the interior cover 1 is installed on the inner side of the exterior cover 2 and is located in the gap between the fan bracket 3 and the exterior cover 2. The interior cover 1 is used to shield the air outlet cover and air duct at the top of the range hood.

[0031] Furthermore, if Figure 2 and Figure 3 As shown, the interior trim cover 1 is provided with a pressure regulating member 11 which can press against the exterior trim cover 2. The pressure regulating member 11 can adjust its own pressing force on the exterior trim cover 2. With the difference in the pressing force, the friction between the surface of the pressure regulating member 11 and the exterior trim cover 2 is different. Thus, the interior trim cover 1 is either pressed and installed on the exterior trim cover 2 or is in a relatively movable state with the exterior trim cover 2, which is convenient for height adjustment and fixed installation of the interior trim cover 1.

[0032] Specifically, the pressure regulating member 11 has two positions. When it is in the first position, the pressure regulating member 11 has no pressing force or a small pressing force on the outer cover 2, and the interior cover 1 can move relative to the outer cover 2; when it is in the second position, the pressure regulating member 11 increases the pressing force on the outer cover 2 so that the interior cover 1 is pressed and installed on the outer cover 2.

[0033] According to an exemplary embodiment of the present application, Figure 4 As shown, both the interior cover 1 and the exterior cover 2 are composed of a U-shaped body consisting of a side panel, a front panel, and a side panel connected in sequence. The rear part of the side panel of the interior cover 1 is provided with a first folded edge 21 bent inwardly, and the rear part of the side panel of the exterior cover 2 is provided with a second folded edge 22 bent inwardly. The first folded edge 21 and the second folded edge 22 are arranged correspondingly. Preferably, the angles between the two folded edges and the connected side panels are both 90°. The pressure regulating member 11 is arranged on the first folded edge 21, which can be moved in the front and rear directions of the range hood, and can press the second folded edge 22 backward to adjust the pressing force on the second folded edge 22. Preferably, the number of the pressure regulating members 11 is 2, which are respectively arranged on the two first folded edges 21 of the interior cover 1. Therefore, the height adjustment and fixed installation of the interior cover 1 can be achieved through the friction between the surface of the pressure regulating member 11 and the second folded edge 22.

[0034] The front and rear directions in the present application refer to the directions of approaching and moving away from the user, respectively, when the range hood is normally used.

[0035] It should be noted that, in the second position, since the pressure regulating member 11 exerts a backward pressing force on the second folded edge 22, the second folded edge 22 also exerts a reverse forward thrust on the pressure regulating member 11, pressing the front plate of the interior trim cover 1 and the inner side of the front plate of the exterior trim cover 2, so that the interior trim cover 1 is clamped and fixed by the exterior trim cover 2 at the front and rear.

[0036] Regarding how to arrange the pressure regulating member 11 on the interior trim cover 1, the present application proposes an exemplary embodiment, such as Figure 4 and Figure 5 As shown, the first folded edge 21 is provided with a mounting section 211 protruding forward. Optionally, the mounting section 211 is in a "F" shape, including a top plate 211a and waist plates 211b extending backward from both sides of the top plate 211a, and the pressure regulating member 11 is movably connected to the top plate 211a, and its movable direction is the front-to-back direction, and the movable range at least includes the above-mentioned first position and second position.

[0037] Furthermore, if Figure 3As shown, the pressure regulating member 11 includes a first end 111, a second end 112 and an adjusting rod 113 located therebetween. The adjusting rod 113 is constructed to be screwably connected to the top plate 211a, and the "screwably connected" here means that the adjusting rod 113 is rotationally connected to the top plate 211a and the displacement of the first end 111 in the front-rear direction of the range hood can be adjusted by rotation to change the pressing force of the first end 111 on the second folded edge 22. Wherein, in the second position, the first end 111 protrudes backwards from the plane where the first folded edge 21 is located to press against the second folded edge 22. Preferably, in the first position, the first end 111 does not protrude from the plane where the first folded edge 21 is located so that the lower end of the interior cover 1 can slide smoothly into the inner side of the exterior cover 2 during installation.

[0038] Optionally, the adjusting rod 113 is threadedly connected to the top plate 211a, and the top plate 211a is provided with a threaded hole 211c for the adjusting rod 113 to pass through and be threadedly connected. The second end 112 is configured as a boss shape, the diameter of which is larger than the diameter of the adjusting rod 113, and the circumferential side wall is provided with a texture for increasing friction, so that the user can rotate the pressure adjusting member 11 during installation.

[0039] Alternatively, if Figure 3 and Figure 6 As shown, the first end 111 is sleeved with an elastic member 111a for pressing the second folded edge 22, thereby avoiding the wear of parts caused by direct scraping between the first end 111 and the second folded edge 22. The pressing surface of the elastic member 111a pressing the second folded edge 22 is set as a rough surface, which helps to increase the friction coefficient between the first end 111 and the second folded edge 22 and improve the stability of the installation structure. The area of ​​the pressing surface is larger than the cross-sectional area of ​​the first end 111, which is also to increase the friction area and improve the structural stability.

[0040] According to an exemplary embodiment of the present application, the pressure regulating member 11 can also be arranged on the side panel of the interior decoration cover 1, pressing the inner side of the side panel of the exterior decoration cover 2 from the inside to both sides, and adjusting its own pressure on the side panel of the exterior decoration cover 2, so as to realize the height adjustment and fixed installation of the interior decoration cover 1, which will not be repeated here.

[0041] This application also proposes a range hood embodiment, see Figure 1 The range hood comprises a fan bracket 3 and the above-mentioned range hood decorative cover mounting structure, wherein a fan is arranged inside the fan bracket 3, the exterior decorative cover 2 is located at the periphery of the fan bracket 3, and the lower end of the interior decorative cover 1 is located between the fan bracket 3 and the exterior decorative cover 2. The height adjustment and fixed installation of the interior decorative cover 1 can be realized by the above-mentioned pressure adjusting member 11.

[0042] According to an exemplary embodiment of the present application, the pressure regulating member 11 and the fan bracket 3 do not overlap in the front projection of the range hood, and the front projection of the range hood refers to the projection from front to back in its usual use state.

[0043] Specifically, when the pressure regulating member 11 is arranged on the first folded edge 21, the pressure regulating member 11 is actually located between the gap between the side panel of the exterior cover 2 and the side panel of the fan bracket 3. The fan bracket 3 is designed in this way so as not to interfere with the movement of the pressure regulating member 11 in the front and rear directions, thereby facilitating the user to adjust the height and install the interior cover 1.

[0044] The components of different embodiments may be combined with each other in any feasible manner to achieve the purpose of this application.

[0045] It should be noted that the present application should not be understood as being limited to the above-described implementation methods, but should be understood as covering all possible implementations determined by the claims of the present application in combination with the disclosure of the specification. Therefore, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the present application without departing from the content of the technical solution of the present application shall fall within the protection scope of the technical solution of the present application.
