[0028] Further as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, it is worth noting that the noise reduction component 4 includes a sound insulation board 41, which is fixed to the outer side wall of the pipe body 1, a polyester fiber sound-absorbing board 42 is fixed to the inner side wall of the pipe body 1, and a sound-absorbing cotton 43 is fixed to one side wall of the polyester fiber sound-absorbing board 42, a gypsum frame 44 is fixed to the inner side wall of the pipe body 1, and a damping sound insulation felt 45 is fixed to one side wall of the gypsum frame 44;

[0029] It should be noted that by setting up the noise reduction component 4, the generation of wind noise can be reduced to a greater extent, and the wind noise can be offset and blocked, thereby ensuring that the user is in a relatively quiet environment when using the fan, which can improve the comfort of use and effectively solve the problem of excessive noise affecting use and quality of life.

[0030] Further as Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, it is worth specifically explaining that the disassembly and assembly component 8 includes a rotating rod 81, which is rotatably connected to the side wall of one side of the connecting plate 7, and a transmission wheel 82 is tightly sleeved on the outer surface of the rotating rod 81, and a rotating wheel 83 is coaxially fixed to one end of the rotating rod 81; two mounting blocks 84, which are symmetrically distributed and fixed to the side wall of one side of the connecting plate 7, and the side wall of one side of the mounting block 84 slides through the limiting rod 85, and the outer surface of the limiting rod 85 is tightly sleeved with a connecting ring 86, and the outer surface of the limiting rod 85 is sleeved with a spring 87, one end of the spring 87 is fixed to the side wall of one side of the connecting ring 86, and the other end of the spring 87 is fixed to the side wall of one side of the mounting block 84; two additional plates 810, which are symmetrically fixed to the outer side wall of the pipe body 1, and a limiting hole 88 is provided on one side wall of the additional plate 810, and the limiting rod 85 is adapted to the limiting hole 88, and a connecting rod 89 is hinged between the limiting rod 85 and the transmission wheel 82;

The disassembly and assembly method is simple and highly reliable.

[0032] This solution has the following working process: when the technician uses this device, by docking the pipe body 1 with the fan and installing and fixing the fan through the mounting hole groove 3, the polyester fiber sound-absorbing panel 42 and the sound-absorbing cotton 43 are arranged to absorb the wind noise in the pipe body 1, and use the sound insulation panel 41 to soundproof the noise outside the pipe body 1. By using the gypsum frame 44 and the damping sound insulation felt 45, the wind noise in the pipe body 1 is reduced. When the filter plate 6 needs to be removed for cleaning, the rotating wheel 83 is rotated to make the rotating rod 81 rotate synchronously, driving the transmission wheel 82 to rotate synchronously, and using the transmission action of the connecting rod 89 to cause the limit rod 85 to move synchronously. At this time, the spring 87 is in a compressed state to ensure that the limit rod 85 is separated from the limit hole 88, and then the limit state of the two filter plates 6 is released, and the two filter plates 6 can be pulled out of the pipe body 1.

Through the setting of the disassembly and assembly component 8, the disassembly and assembly of the two filter plates 6 can be completed quickly, and the disassembly and assembly of the filter plate 6 can be completed without the use of tools. The disassembly and assembly method of the filter plate 6 is simple and the disassembly and assembly efficiency is high, thereby better meeting the work needs of the staff for the disassembly and assembly of the filter plate 6. The disassembly and assembly method is simple and the reliability is high.

[0034] Further as Figure 1 and Figure 4 As shown, it is worth noting that the inner side wall of the pipe body 1 is provided with two symmetrically distributed positioning grooves 9, the positioning grooves 9 are connected to the interior of the through groove 5, and the filter plate 6 is slidably connected to the positioning grooves 9;

[0035] It should be noted that by sliding the filter plate 6 in the positioning groove 9, it can not only guide the filter plate 6, but also improve the stability of the filter plate 6 when used in the pipe body 1, and then improve the stability and smoothness of the filter plate 6 when pulling and moving.
