Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example
[0026] Based on the existing issue of potential detachment due to external forces during installation and use, please refer to [link / reference needed]. Figures 1-3 This utility model provides a technical solution: an adjustable hood with an anti-detachment structure, including a hood body 1, an anti-detachment mechanism 2 provided on the outer side of the hood body 1, and a filter mechanism 3 provided below the anti-detachment mechanism 2.
[0027] The anti-fall-off mechanism 2 includes a placement part 21 and an anti-fall-off part 22;
[0028] The anti-fall-off part 22 is located on the inner side of the placement part 21;
[0029] The filter mechanism 3 includes a filter section 31 and a pull-out section 32;
[0030] The pull-out section 32 is located on the inner side of the filter section 31.
[0031] The placement part 21 includes a placement box 211, a fixing box 212 is provided on the bottom surface of the placement box 211, the placement box 211 is fixedly connected to the fixing box 212, a rotating handle 213 is provided on the outer side of the fixing box 212, and a threaded rod 214 is provided on the inner end face of the rotating handle 213, and the threaded rod 214 is fixedly connected to the rotating handle 213.
[0032] The threaded rod 214 extends through to the inner side of the fixed box 212. The fixed box 212 is threadedly connected to the threaded rod 214. An auxiliary plate 215 is provided on the inner end face of the threaded rod 214. The auxiliary plate 215 is rotatably connected to the threaded rod 214.
[0033] The anti-detachment part 22 includes an anti-detachment plate 221. The outer side of the anti-detachment plate 221 is fixedly connected to the inner side of the auxiliary plate 215. A slider 222 is provided on the outer side of the anti-detachment plate 221. The slider 222 is fixedly connected to the anti-detachment plate 221. A sliding rod 223 is provided through the inner wall of the slider 222. The sliding rod 223 is slidably connected to the slider 222.
[0034] The outer end face of the slide rod 223 is fixedly connected to the inner side of the fixed box 212. The inner side of the slide rod 223 is provided with anti-slip pads 224, and the outer side of the anti-slip pads 224 is fixedly connected to the inner side of the anti-drop plate 221.
[0035] Furthermore, in this embodiment, through the anti-detachment mechanism 2, the placement box 211 and the fixing box 212 in the placement part 21 are used. When it is necessary to install the hood body 1 into place, the hood body 1 is first passed through the placement box 211 and enters the fixing box 212. Then, the rotating handle 213 is operated to rotate. The rotation of the rotating handle 213 drives the threaded rod 214 connected to it to rotate. The linear movement of the threaded rod 214 further pushes the movement of the auxiliary plate 215. As the auxiliary plate 215 moves, the anti-detachment plate 221 and the anti-slip pad 224 slide smoothly along the surface of the sliding rod 223 under the guidance of the slider 222, so that the anti-detachment plate 221 and the anti-slip pad 224 gradually approach and finally clamp the hood body 1. When the anti-detachment plate 221 and the anti-slip pad 224 are completely attached and clamp the hood body 1, the entire anti-detachment mechanism 2 completes the fixation of the hood body 1.
[0036] Furthermore, in this embodiment, the anti-fall-off mechanism 2 utilizes the placement box 211 and the fixing box 212 in the placement part 21. When the hood body 1 needs to be installed, the hood body 1 passes through the placement box 211 and the fixing box 212, thereby rotating the handle 213. The handle 213 drives the threaded rod 214, the threaded rod 214 drives the auxiliary plate 215, and the auxiliary plate 215 drives the anti-fall-off plate 221 and the anti-slip pad 224 to slide on the surface of the sliding rod 223 under the action of the slider 222, thereby clamping and fixing the hood body 1 and preventing the hood body 1 from falling off. Example
[0037] Please see Figure 1 , Figure 2 , Figure 4Furthermore, based on Embodiment 1, the following is obtained: the filter section 31 includes a filter box 311, the top surface of the filter box 311 is fixedly connected to the bottom surface of the fixed box 212, a through groove is provided on the front side of the filter box 311, a fixed base 312 is provided on the bottom surface of the filter box 311, the fixed base 312 is fixedly connected to the filter box 311, and a sliding groove 313 is provided on the top of the fixed base 312, which is fixedly connected to the inner side of the filter box 311.
[0038] The pull-out part 32 includes a filter screen 321, which is located on the inner side of the slide groove 313 and is slidably connected to the slide groove 313. The filter screen 321 extends through to the front side of the through groove and is slidably connected to the through groove. A baffle 322 is provided on the front side of the filter screen 321 and is fixedly connected to the filter screen 321. A handle 323 is fixedly provided on the front side of the baffle 322.
[0039] Furthermore, in this embodiment, through the filter mechanism 3, the filter screen 321 of the pull-out part 32 filters smoke or air, which then flows out or enters the room through the hood body 1. During use, particulate matter and harmful substances in outdoor air or smoke are effectively intercepted by the filter screen 321. Over time, the filter screen 321 may become clogged due to the accumulation of too many particulate matter. At this time, it needs to be cleaned or replaced. The user first pulls the handle 323, which moves the baffle 322. Under the action of the baffle 322, the filter screen 321 slides along the inner side of the slide groove 313 and is finally pulled out from the filter box 311. Once the filter screen 321 is pulled out, the user can clean or replace it. The cleaned filter screen 321 or the new filter screen 321 can be reinstalled in the filter box 311 in reverse order to continue performing the filtration task.
[0040] Furthermore, in this embodiment, the filter mechanism 3 utilizes the filter screen 321 in the pull-out part 32. During use, the smoke is filtered and flows out or into the hood body 1. When the filter screen 321 is clogged, the handle 323 is pulled, which drives the baffle 322. The baffle 322 drives the filter screen 321 to be pulled out of the filter box 311 from the inner side of the slide 313, effectively filtering particulate matter and harmful substances in the outdoor air and improving the air quality entering the room.
[0041] In use, it is placed in the preset through hole and fixed by external means using the fixed base 312. Then, using the anti-drop mechanism 2, the placement box 211 and the fixed box 212 in the placement part 21 are used to install the hood body 1. First, the hood body 1 is passed through the placement box 211 and into the fixed box 212. Then, the handle 213 is rotated. The rotation of the handle 213 drives the connected threaded rod 214 to rotate. The linear movement of the threaded rod 214 further pushes the movement of the auxiliary plate 215. As the auxiliary plate 215 moves, the anti-drop plate 221 and the anti-slip pad 224 slide smoothly along the surface of the slide rod 223 under the guidance of the slider 222, so that the anti-drop plate 221 and the anti-slip pad 224 gradually approach and finally clamp the hood body 1. When the anti-drop plate 221 and the anti-slip pad 224 are completely closed, the hood body 1 is clamped. When the hood body 1 is attached and clamped, the entire anti-detachment mechanism 2 secures the hood body 1. During use, smoke or air is filtered through the filter screen 321 of the pull-out part 32 via the filter mechanism 3. The filtered air then flows out through the hood body 1 or into the room. During use, particulate matter and harmful substances in outdoor air or smoke are effectively intercepted by the filter screen 321. Over time, the filter screen 321 may become clogged due to excessive accumulation of particulate matter. In this case, it needs to be cleaned or replaced. The user first pulls the handle 323, which moves the baffle 322. Driven by the baffle 322, the filter screen 321 slides along the inner side of the groove 313 and is eventually pulled out of the filter box 311. Once the filter screen 321 is removed, the user can clean or replace it. The cleaned filter screen 321 or a new filter screen 321 can be reinstalled in the filter box 311 in reverse order to continue the filtration task.
