[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments, but this is not to limit the scope of the present invention.

[0026] like Figures 1 to 4 As shown, this embodiment addresses the problem of existing exhaust fans 40 lacking protective structures. To this end, this embodiment provides an easily installable stainless steel exhaust cover, installed inside a window opening, to protect the exhaust fan 40 installed on the window. The structure is safer to use. The stainless steel exhaust cover includes an L-shaped mesh cover 1 and two opposing support rails 2. Both the mesh cover 1 and the support rails 2 are preferably made of stainless steel for greater durability. The mesh cover 1 includes a perforated plate 11 and a frame 12 along the periphery of the perforated plate 11. The frame 12 on both sides of the horizontal arm of the mesh cover 1 is provided with slots 121. The two support rails 2 are respectively fixedly installed on both sides of the window opening. During installation, the two support rails 2 slide into their corresponding slots 121, thus providing support and fixing points for the mesh cover 1.

[0027] Specifically, in practical application, the easy-to-install stainless steel exhaust cover described in this embodiment is installed by fixing two support rails 2 horizontally on the walls on both sides of the window opening. Then, the slot 121 of the mesh cover 1 is placed at the same horizontal height as the support rails 2 on both sides of the window opening. The mesh cover 1 is then pushed into the window opening, and the support rails 2 enter the slot 121 from the end of the slot 121, thus pushing the mesh cover 1 horizontally until it is completely pushed into the window opening. At this time, the mesh cover 1 is supported and fixed by the cooperation of the support rails 2 and the slot 121, so that the mesh cover 1 is fixed in the window opening, thereby forming protection for the exhaust fan 40 and also achieving the purpose of blocking the exhaust fan 40. The structure is more aesthetically pleasing. When it is necessary to disassemble the mesh cover 1, simply pull the mesh cover 1 outward.

[0028] This embodiment uses an L-shaped mesh cover 1 and two supporting guide rails 2, with slots 121 on both sides of the horizontal arm of the mesh cover 1. During installation, the two supporting guide rails 2 are fixed horizontally to the walls on both sides of the window opening. The mesh cover 1 is then fixed inside the window opening by the cooperation of the supporting guide rails 2 and the slots 121, thus forming a protective structure for the exhaust fan 40. This not only conceals the exhaust fan but also achieves a more aesthetically pleasing effect. When it is necessary to remove the mesh cover 1, it can be simply pulled outwards. The overall structure is simple and the disassembly and assembly are extremely convenient, which helps to improve the user experience and safety of the window exhaust fan.

[0029] like Figure 2 and Figure 4 As shown in this embodiment, the easily installable stainless steel exhaust hood, in some embodiments, further includes a snap-fit ​​assembly for fixing the longitudinal arm of the mesh cover 1. This embodiment uses the snap-fit ​​assembly to fix the top of the mesh cover 1, thereby making the mesh cover 1 more stably fixed inside the window opening, resulting in higher structural reliability.

[0030] like Figure 2 and Figure 4 As shown in the embodiment, the easy-to-install stainless steel exhaust hood described in this embodiment, in some implementations, includes two spaced-apart brackets 31 and two spaced-apart blocks 13 located at the top of the longitudinal arm of the mesh cover 1; during installation, the two blocks 13 are elastically fastened to the corresponding brackets 31, thereby fixing the top of the mesh cover 1. In this embodiment, through the above-described configuration, during installation, the two brackets 31 are fixedly installed on the inner top wall of the window opening. When the mesh cover 1 is pushed into place, the two blocks 13 elastically fasten to the corresponding brackets 31, thereby fixing the mesh cover 1 and making the mesh cover 1 more secure during use.

[0031] Furthermore, the card holder 31 is provided with a first card slot, and elastic locking pins are provided on both sides of the second card slot (not shown in the figure). Second card slots are provided on both sides of the card block 13 (not shown in the figure). The elastic locking pins and the second card slots are lockably engaged. During installation, the card block 13 is inserted into the first card slot and squeezes the elastic locking pin, causing the elastic locking pin to retract until it is inserted into the second card slot, locking the card block 13 in an unlockable manner. During disassembly, by pulling the mesh cover 1, the card block 13 is squeezed inward, causing the elastic locking pin to retract, thereby releasing the locking engagement between the elastic locking pin and the second card slot, so that the mesh cover 1 can be pulled out of the window opening.

[0032] like Figure 3As shown in the figure, in some embodiments of the easy-to-install stainless steel exhaust cover described in this embodiment, the slot 121 is a V-shaped or U-shaped slot formed by bending the frame 12 of the mesh cover 1. This embodiment, through the above-described design, makes the mesh cover 1 easier to manufacture and facilitates the cooperation between the support rail 2 and the slot 121.

[0033] like Figure 4 As shown, in some embodiments of the easily installable stainless steel exhaust hood described in this embodiment, the supporting guide rail 2 is L-shaped. This embodiment uses the above-described design to facilitate the installation of the supporting guide rail 2 and also to facilitate the engagement of the supporting guide rail 2 with the slot 121. Preferably, the supporting guide rail 2 has a sheet-like structure.

[0034] Example 2: Figure 1 , Figures 5 to 8 As shown, the difference between this embodiment and the above embodiment is that the structure of the buckle assembly is different, while the rest of the structure is the same as that of embodiment one. The buckle assembly of this embodiment includes an elastic claw 32 and two strip-shaped buckle holes 122 spaced apart at the top of the longitudinal arm of the mesh cover 1. The two ends of the elastic claw 32 are respectively provided with V-shaped portions 321. During installation, the V-shaped portions 321 at both ends of the elastic claw 32 are inserted into the corresponding strip-shaped buckle holes 122, thereby fixing the top of the mesh cover 1.

[0035] Specifically, in this embodiment, the stainless steel exhaust hood that is easy to install moves along the slot 121 during the process of pushing the mesh cover 1 into the window opening. When the mesh cover 1 is about to be pushed into place, the V-shaped part 321 of the elastic claw 32 contacts and abuts against the top position of the mesh cover 1. The mesh cover 1 squeezes the V-shaped part 321 of the elastic claw 32, causing the V-shaped part 321 of the elastic claw 32 to deform and expand outward. During the outward expansion of the V-shaped part 321, the end of the V-shaped part 321 is inserted into the strip-shaped hole 122. At this time, the elastic claw 32 is reset, and the V-shaped part 321 of the elastic claw 32 forms an elastic pulling force on the mesh cover 1, which forms an elastic lock on the mesh cover 1 and forms an automatic centering effect on the mesh cover 1. In this way, the mesh cover 1 can be fixed and centered.

[0036] When disassembly is required, simply pull the mesh cover 1 outward. During the process of pulling the mesh cover 1 outward, the V-shaped part 321 undergoes elastic deformation and expands outward until the V-shaped part 321 automatically disengages from the strip-shaped locking hole 122, completing the automatic unlocking of the mesh cover 1. At this point, the mesh cover 1 can be completely pulled out of the window opening to complete the disassembly.

[0037] Compared to Embodiment 1, this embodiment, in addition to achieving the same technical effects, uses the elastic claws 32 and strip-shaped locking holes 122 to fix the top of the mesh cover 1. This not only achieves the fixing effect of the mesh cover 1 but also provides a centering effect, making the installation of the mesh cover 1 more aesthetically pleasing and facilitating the force balance of the two side support rails 2. At the same time, since the elastic claws 32 engage with the strip-shaped locking holes 122 during outward expansion, compared to the method of the locking block 13 and the locking seat 31 corresponding to the elastic buckle, it can reduce the accuracy requirements of the mesh cover 1's dimensions and the installation accuracy of the locking components, thereby reducing the difficulty of installing the mesh cover 1 and making the installation operation of the mesh cover 1 more convenient.

[0038] like Figures 5 to 7 As shown, in some embodiments of the easily installable stainless steel exhaust hood described in this embodiment, a V-shaped groove 123 is horizontally provided on one side of the top of the longitudinal arm of the mesh cover 1; two strip-shaped locking holes 122 are provided through the bottom of the V-shaped groove 123. In this embodiment, by providing the V-shaped groove 123, during installation, the V-shaped portion 321 of the elastic claw 32 first enters the V-shaped groove 123. The V-shaped groove 123 provides a guiding and limiting effect for the outward expansion of the V-shaped portion 321, allowing the V-shaped portion 321 to reliably engage in the locking hole, resulting in higher structural reliability.

[0039] like Figure 8 As shown in the figure, in some embodiments of the easily installable stainless steel exhaust hood described in this embodiment, the buckle assembly further includes a fixing block 33; the elastic claw 32 is fixed to the fixing block 33 at its center. Specifically, the fixing block 33 is fixedly installed on the inner top wall of the window opening. This embodiment uses the fixing block 33 to facilitate the installation and fixation of the elastic claw 32.

[0040] The above description is only a preferred embodiment of the present utility model. Therefore, any equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included within the protection scope of the present utility model patent application.
