DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model 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.

[0022] Please refer to Figures 1-4 As shown, a building ventilation structure includes a pipe main body 1. One end of the pipe main body 1 near the upper part is fixedly connected with a mounting plate 2. A bolt 3 penetrates through the surface of the mounting plate 2. A fixing plate 4 is fixedly connected at a position near the upper part inside the pipe main body 1. One side of the fixing plate 4 is rotatably connected with a fan blade 5, and the other side of the fixing plate 4 is fixedly connected with a motor 6. A card slot 8 is formed on the surface of the pipe main body 1, and a filter plate 9 is snap-fitted inside the card slot 8. A cleaning assembly 12 is fixedly connected to the inner wall of the pipe main body 1 below the filter plate 9.

[0023] Further, the cleaning assembly 12 includes a mounting frame 121. A brush plate 122 is rotatably connected above the mounting frame 121. One side of the bottom of the brush plate 122 is fixedly connected with one side of a gear set 123, and the other side of the gear set 123 is fixedly connected with one end of a connecting rod 124. The other end of the connecting rod 124 is fixedly connected with a crank 125.

[0024] During operation, due to the structural design that both ends of the connecting rod 124 are fixedly connected with the crank 125, the rotation of the brush plate 122 is controlled by rotating the crank 125, and the structure is simple and easy to operate.

[0025] Further, the surface of the connecting rod 124 is rotatably connected with the bottom of the mounting frame 121, and the side view of the mounting frame 121 is triangular.

[0026] During operation, due to the structural design that the side view of the mounting frame 121 is triangular, the possibility of dust accumulating on the surface of the mounting frame 121 is reduced.

[0027] Further, a rotating rod 11 is rotatably connected to the surface of the pipe main body 1, and the inner side of the rotating rod 11 abuts against the surface of the filter plate 9.

[0028] During operation, due to the structural design that the inner side of the rotating rod 11 abuts against the surface of the filter plate 9, the rotating rod 11 has a limiting effect on the filter plate 9, and the sealing performance during the installation of the filter plate 9 is improved.

[0029] Further, a clamping block 10 is fixedly connected to the inner wall of the pipe main body 1, and the top surface of the clamping block 10 is closely attached to the bottom surface of the filter plate 9.

[0030] During operation, due to the structural design that the top surface of the clamping block 10 closely adheres to the bottom surface of the filter plate 9, the clamping block 10 provides a supporting effect on the filter plate 9, improving the stability of the filter plate 9 during installation inside the pipeline main body 1.

[0031] Furthermore, a support frame 7 is fixedly connected to a position near the lower part of the surface of the pipeline main body 1, and the bottom end of the support frame 7 is lower than the bottom end of the pipeline main body 1;

[0032] During operation, due to the structural design that the bottom end of the support frame 7 on the surface of the pipeline main body 1 is lower than the bottom end of the pipeline main body 1, the support frame 7 provides a supporting effect on the pipeline main body 1.

[0033] Working principle: The mounting plate 2 is fixedly installed on the outer wall of the building through bolts 3. The support frame 7 on the surface of the pipeline main body 1 supports on the ground. The motor 6 is started through an external power supply. The motor 6 drives the fan blade 5 to rotate, and air enters from below the pipeline main body 1. The filter plate 9 filters the air. After a large amount of dust accumulates on the surface of the filter plate 9 during the long-term operation of the device, the handle 125 is rotated to drive the connecting rod 124 to drive the gear set 123, so that the brush plate 122 sweeps the bottom surface of the filter plate 9;

[0034] When the filter plate 9 needs to be maintained and repaired, the rotating rod 11 is rotated upward to separate between the inner wall of the rotating rod 11 and the outer wall of the filter plate 9, and then the filter plate 9 is slid out. When installing the filter plate 9, the filter plate 9 is snap-fitted into the card slot 8, and the clamping block 10 provides a supporting effect on the filter plate 9.

[0035] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
