Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] like Figures 1 to 7 As shown, the utility model provides a detachable ventilation duct filter dust cover, comprising a duct body 1, a dust cover body 2, an air filter 3 and a filter screen 4;

[0027] The right side of the pipe body 1 is movably connected to the left side of the dust cover body 2. The interior of the dust cover body 2 is fixedly connected to the surfaces of the air filter 3 and the filter screen 4 respectively. The air filter 3 is located on the left side of the filter screen 4, and the right side of the filter screen 4 extends to the outside of the dust cover body 2.

[0028] The surfaces of the pipe body 1 and the dust cover body 2 are fixedly connected with a connecting plate 5, and the two connecting plates 5 fit together. An opening 6 is provided on the surface of the connecting plate 5. The top and bottom of the dust cover body 2 are fixedly connected with an auxiliary block 7 located on the right side of the connecting plate 5. The left side of the auxiliary block 7 is fixedly connected with a hook 8. The left side of the hook 8 passes through the opening 6 and the connecting plate 5 in sequence and extends to the left side of the connecting plate 5. A compression spring 9 is provided on the left side of the auxiliary block 7. The front and back sides of the compression spring 9 are fixedly connected to the surface of the hook 8.

[0029] refer to Figure 4 The left side of the dust cover body 2 is fixedly connected to a fixing bracket 10, and the left side of the fixing bracket 10 extends to the inside of the pipe body 1. The surface of the fixing bracket 10 is provided with a mounting groove 11 located inside the pipe body 1. The inside of the mounting groove 11 is fixedly connected to a filling rubber 12, and the outer side of the filling rubber 12 extends to the outside of the mounting groove 11 and is sealed with the inner wall of the pipe body 1.

[0030] As a technical optimization solution of the present invention, by setting the installation groove 11 and the filling rubber 12, the space between the pipe body 1 and the dust cover body 2 is filled, and the filling rubber 12 is used to absorb vibration and reduce the impact of vibration on the filter dust cover.

[0031] refer to Figure 3 The top and bottom of the pipe body 1 are movably connected to a protective shell 13 located on the left side of the connecting plate 5. The inside of the protective shell 13 is movably connected to an auxiliary frame 14. The right side of the auxiliary frame 14 extends to the outside of the protective shell 13 and is fixedly connected to the left side of the connecting plate 5. The auxiliary frame 14 is located outside the opening 6.

[0032] As a technical optimization solution of the present invention, the protective shell 13 and the auxiliary frame 14 are provided to protect the hook 8, thereby preventing workers from accidentally touching the hook 8 when inspecting the ventilation duct.

[0033] refer to Figure 7 The front and back of the auxiliary frame 14 are both provided with guide grooves 15 , and the front and back of the interior of the protective shell 13 are both fixedly connected with sliding blocks 16 , and the inner side of the sliding block 16 extends to the interior of the guide groove 15 .

[0034] As a technical optimization solution of the present invention, the protective shell 13 is limited by providing a guide groove 15 and a sliding block 16 to prevent the protective shell 13 from being displaced in the horizontal direction and causing the protective shell 13 to separate from the auxiliary frame 14.

[0035] refer to Figure 5 The outer side of the auxiliary frame 14 is fixedly connected with an iron sheet 17 , and the inner wall of the protective shell 13 is fixedly connected with a magnet block 18 , and the magnet block 18 is aligned with the iron sheet 17 .

[0036] As a technical optimization solution of the present invention, by setting an iron sheet 17 and a magnet block 18, the protective shell 13 is limited by utilizing the property that the magnet block 18 will adsorb the iron sheet 17, thereby preventing the protective shell 13 from vertically displacing and causing the protective shell 13 to separate from the auxiliary frame 14.

[0037] refer to Figure 6 The outer side of the compression spring 9 is covered with a dustproof cloth 19 , and the front and back sides of the dustproof cloth 19 are fixedly connected to the surface of the hook 8 .

[0038] As a technical optimization solution of the present invention, a dustproof cloth 19 is provided to protect the compression spring 9 to prevent dust and other impurities from adhering to the surface of the compression spring 9, and to prevent water from coming into contact with the compression spring 9, which would cause the compression spring 9 to be damaged due to rust.

[0039] The working principle and usage process of the utility model: when in use, first insert the fixing frame 10 into the pipe body 1, and then move the dust cover body 2 to the left, and the hook 8 follows the dust cover body 2 to move to the left through the auxiliary block 7, so that the hook 8 passes through the opening 6 and the connecting plate 5 located on the pipe body 1. At this time, the hook 8 and the connecting plate 5 will form a snap structure to connect the dust cover body 2 with the pipe body 1. When the dust cover body 2 needs to be disassembled, since the dust cover body 2 and the pipe body 1 are connected by the snap structure, it is only necessary to pull the dust cover body 2 to the right with force, and the dust cover body 2 will be separated from the pipe body 1, making it easy to disassemble and assemble the filter dust cover.

[0040] To sum up: the detachable ventilation duct filter dust cover forms a snap structure by setting an auxiliary block 7, a hook 8, a connecting plate 5 and an opening 6, which quickly connects the duct body 1 and the dust cover body 2, and uses a compression spring 9 to limit the hook 8 to prevent the filter dust cover from vibrating and causing the duct body 1 and the dust cover body 2 to separate. Since it is connected through a snap structure, it is convenient for workers to disassemble and assemble the filter dust cover.
