[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] To further understand the content of the present utility model, the present utility model will be described in detail in conjunction with the accompanying drawings.

[0027] Combined with Figures 1 - 7, An activated carbon filter for easily replacing the filter screen of the present utility model includes a fixed frame 1, an outer cover 2 is fixedly clamped inside the fixed frame 1, two fixing components 3 are respectively fixed on both sides of one side of the fixed frame 1, two limiting components 4 are symmetrically installed on both sides inside the fixed frame 1, a filter material 201 is fixed inside the outer cover 2, and two first fixing frames 203 are fixed at positions corresponding to the fixing components 3 on one side of the outer cover 2, and a fixing rod 204 is fixed on the first fixing frame 203. The fixing component 3 includes a second fixing frame 301 fixed on one side of the fixed frame 1, two auxiliary clamping plates 302 are fixed on one side of the second fixing frame 301, and a special-shaped clamping plate 303 is rotatably connected between the two auxiliary clamping plates 302 through a rotating shaft 3031.

[0028] Specifically, when this case is actually used, the whole outer cover 2 is pushed into the fixed frame 1. When the fixing rod 204 fixed on the first fixing frame 203 contacts the special-shaped clamping plate 303, continue to push so that the special-shaped clamping plate 303 is squeezed upward. The special-shaped clamping plate 303 rotates along the rotating shaft 3031 between the auxiliary clamping plates 302. The fixing rod 204 continues to move inward. After the fixing rod 204 is inserted into the arc-shaped slideway of the auxiliary clamping plate 302, the special-shaped clamping plate 303 falls due to gravity without extrusion, and cooperates with the auxiliary clamping plate 302 to clamp the fixing rod 204, that is, the outer cover 2 is fixed. The limiting component 4 installed inside the fixed frame 1 also further limits and fixes the outer cover 2. When it needs to be disassembled, only need to control the rotation of the special-shaped clamping plate 303 to release the restriction on the fixing rod 204 to complete the disassembly. This group of components is simple to use and easy to operate, and has a good fixing effect, and can realize the quick disassembly, installation and replacement of the outer cover 2, thereby improving the maintenance efficiency and reducing the use cost.

[0029] Combined with Figures 4 - 7 , the limiting component 4 includes a spring 402 fixed in the opening on the inner side of the fixed frame 1, a limiting block 401 is fixed at one end of the spring 402, and a limiting card slot 206 is opened at a position corresponding to the limiting block 401 on the outer cover 2. When in use, when the outer cover 2 slides into the fixed frame 1 and contacts the limiting block 401, the limiting block 401 is squeezed inward, and the spring 402 is compressed. When the outer cover 2 completely slides into the fixed frame 1, the limiting card slot 206 is located at the position of the limiting block 401, and the limiting block 401 is squeezed into the limiting card slot 206 by the resilience of the spring 402 to limit and strengthen the fixation of the outer cover 2, increase the fixing effect and improve the stability of the device.

[0030] On one side of the limit block 401, a pull rope 403 is fixed. The pull rope 403 slides in the rope channel of the fixed frame 1. The other end of the pull rope 403 passes through the fixed frame 1 and the second fixing bracket 301 and is connected to one side of the special-shaped clamping plate 303. When disassembling and assembling the outer cover 2, it is necessary to rotate the special-shaped clamping plate 303 to release the restriction on the fixed rod 204 to achieve the disassembly of the outer cover 2. At this time, the pull rope 403 at the tail of the special-shaped clamping plate 303 is pulled, and the other end limit block 401 slides into the opening. During the process of releasing the fixation of the fixing component 3, the fixation of the limiting component 4 is also released, effectively improving the disassembly and assembly efficiency.

[0031] A pull ring 3032 is fixed at the top of the special-shaped clamping plate 303. Fixing a pull ring 3032 at the top of the special-shaped clamping plate 303 facilitates controlling the rotation of the special-shaped clamping plate 303 during removal, improves the operation convenience, and thus improves the disassembly and assembly efficiency.

[0032] The outer side of the special-shaped clamping plate 303 is designed as an inclined surface, one side of the limit block 401 is designed as an arc, and the contact areas of the auxiliary clamping plate 302 and the special-shaped clamping plate 303 with the fixed rod 204 are all designed as rounded corners. Designing the outer side of the special-shaped clamping plate 303 as an inclined surface facilitates the extrusion of the special-shaped clamping plate 303 by the fixed rod 204 and improves the operation smoothness. Similarly, designing one side of the limit block 401 as an arc is also for facilitating the extrusion of the limit block 401 by the outer cover 2, and designing the contact areas of the auxiliary clamping plate 302 and the special-shaped clamping plate 303 with the fixed rod 204 as rounded corners is also for improving the movement smoothness.

[0033] Combined Figures 2 - 3 and Figures 6 - 7 In the hole where the second fixing bracket 301 is located at the sliding position of the spring 402, an annular anti-wear pad 3011 is fixed. Fixing the annular anti-wear pad 3011 in the sliding hole of the spring 402 of the second fixing bracket 301 can reduce the friction between components, prevent the spring 402 from being worn during long-term use, and improve the service life of the device.

[0034] Two clamping blocks 205 are respectively fixed on the upper and lower parts of the outer cover 2, and corresponding sliding channels 101 are opened in the fixed frame 1. Two clamping blocks 205 are fixed on the upper and lower parts of the outer cover 2 and slide in the sliding channels 101 opened in the fixed frame 1 to achieve the limiting effect and improve the stability of the outer cover 2 inside the fixed frame 1.

[0035] On both sides of the filter material 201 of the outer cover 2, protective nets 202 are fixed. Fixing the protective nets 202 on both sides of the filter material 201 of the outer cover 2 can effectively isolate large objects from entering the filter material 201 and affecting the filtering effect.
