[0026] like Figures 1 to 4 As shown, an air-purifying glass fiber fluffy filter felt includes a felt body 1, which includes two sets of outer felt layers 101 and an inner felt layer 102. The two sets of outer felt layers 101 are respectively installed on the front and rear sides of the inner felt layer 102. A positioning mechanism 3 is sleeved on the outer surface of the inner felt layer 102 to limit the movement range of the felt body 1 during use. The front and rear sides of the positioning mechanism 3 are respectively attached to the adjacent side of the two sets of outer felt layers 101. Specifically, by adjusting the positioning mechanism 3, the left and right sides of the positioning mechanism 3 are respectively abutted against the inner wall of the felt positioning area, thereby reducing the time spent by the staff when positioning and installing the felt body 1 inside certain exhaust pipes, thus improving the practicality of the device.

[0027] like Figures 1 to 4 As shown, the positioning mechanism 3 includes a U-shaped fixing plate 301, which is sleeved on the outer surface of the inner felt layer 102. The front and rear sides of the U-shaped fixing plate 301 abut against the adjacent sides of the two sets of outer felt layers 101. The left and right sides of the U-shaped fixing plate 301 are provided with slots. The adjacent sides of the two sets of slots of the U-shaped fixing plate 301 are each equipped with a spring 303.

The adjacent sides of the two sets of limit blocks 4 abut against the opposite sides of the two sets of protective cover plates 302.

[0028] Specifically, by pulling the two sets of limiting blocks 4, the limiting blocks 4 are moved out of the two sets of positioning clamping grooves of the front group of outer felt layers 101 and the back-shaped fixing plate 301, so that the two sets of springs 303 push the two sets of protective cover plates 302 to pop out of the two sets of clamping grooves of the back-shaped fixing plate 301, and then the opposite sides of the two sets of protective cover plates 302 are respectively abutted against the inner wall of the felt positioning area, thereby reducing the time consumed by the subsequent workers when positioning and installing the felt main body 1 inside the part of the exhaust pipe, and thus improving the practicability of the device; by sleeving the felt main body 1 on the outer end of the positioning mechanism 3, the positioning mechanism 3 and the felt main body 1 can be disassembled, and then the subsequent positioning mechanism 3 can be recycled, thereby avoiding subsequent resource waste as much as possible.

[0029] As shown in Figure 2 , the opposite sides of the two sets of protective cover plates 302 are both provided with clamping grooves, and the clamping groove interiors of the two sets of protective cover plates 302 are both installed with anti-skid pads 5; specifically, by setting the positions of the two sets of anti-skid pads 5 between the two sets of protective cover plates 302 and the inner wall of the felt positioning area, the two sets of anti-skid pads 5 increase the friction force of the contact surface between the two sets of protective cover plates 302 and the inner wall of the felt positioning area during the subsequent use of the two sets of protective cover plates 302, thereby avoiding the subsequent movement of the positioning mechanism 3 after being installed and positioned inside the felt positioning area as much as possible, and thus improving the stability of the positioning mechanism 3 during use.

[0030] As shown in Figure 2 , the back inner walls of the two sets of clamping grooves of the back-shaped fixing plate 301 are both provided with positioning grooves 6, the positions of the two sets of positioning grooves 6 are respectively located on the movement paths of the two sets of limiting blocks 4, and the outer contours of the two sets of limiting blocks 4 are respectively matched with the inner contours of the adjacent set of positioning grooves 6; specifically, by pushing the two sets of limiting blocks 4, the backs of the two sets of limiting blocks 4 are respectively inserted into the two sets of positioning grooves 6, so that the inner contours of the two sets of positioning grooves 6 limit the movement positions of the two sets of limiting blocks 4 during the limiting process, thereby avoiding the two sets of limiting blocks 4 from falling off from the two sets of positioning clamping grooves of the front group of outer felt layers 101 and the back-shaped fixing plate 301 during the subsequent workers carrying and moving the felt as much as possible, and thus improving the stability of the limiting blocks 4 during idle carrying.

[0031] As shown in Figure 1 and Figure 2As shown, the front side of the outer felt layer 101 and the front side of the back-shaped fixing plate 301 are provided with a plurality of through holes, and the inner side of the through holes of the outer felt layer 101 and the back-shaped fixing plate 301 are respectively provided with a plurality of positioning protrusions 2. Specifically, when the subsequent positioning mechanism 3 is sleeved on the outer end of the inner felt layer 102, the plurality of positioning protrusions 2 are inserted into the plurality of through holes of the outer felt layer 101 and the plurality of through holes of the back-shaped fixing plate 301, so that the subsequent plurality of positioning protrusions 2 limit the movement position of the positioning mechanism 3 at the outer end of the inner felt layer 102, thereby avoiding the outer felt layer 101 from falling off the outer end of the positioning mechanism 3 during the use of the device, and improving the stability of the positioning mechanism 3 during use.

[0032] As shown in the figure, Figure 4 The inner diameter and density of the inner felt layer 102 are smaller than those of the outer felt layer 101. Specifically, by setting the inner diameter and density of the inner felt layer 102 to be smaller than those of the outer felt layer 101, and by setting the position of the inner felt layer 102 between the two outer felt layers 101, the subsequent inner felt layer 102 filters the fine particles filtered by the outer felt layer 101, thereby improving the filtering efficiency of the subsequent felt body 1 during use, and improving the practicality of the device.

[0033] In summary, by pulling the two limiting blocks 4, the limiting blocks 4 are moved out of the two positioning slots of the outer felt layer 101 and the back-shaped fixing plate 301, so that the two springs 303 push the two protective cover plates 302 out of the two slots of the back-shaped fixing plate 301, and then the opposite sides of the two protective cover plates 302 abut against the inner wall of the felt positioning area, thereby reducing the time consumed by the subsequent workers when positioning and installing the felt body 1 in the part of the exhaust pipe. By pushing the two limiting blocks 4, the back surface of the two limiting blocks 4 is respectively inserted into the two positioning grooves 6, so that the inner contour of the two positioning grooves 6 limits the movement position of the two limiting blocks 4 during the limiting process, thereby avoiding the two limiting blocks 4 from falling off the two positioning slots of the outer felt layer 101 and the back-shaped fixing plate 301 during the subsequent workers carrying and moving the felt.

[0034] At the same time, by pushing the plurality of positioning protrusions 2, the plurality of positioning protrusions 2 are inserted into the plurality of through holes of the outer felt layer 101 and the plurality of through holes of the back-shaped fixing plate 301, so that the subsequent plurality of positioning protrusions 2 limit the movement position of the positioning mechanism 3 at the outer end of the inner felt layer 102, thereby avoiding the outer felt layer 101 from falling off the outer end of the positioning mechanism 3 during the use of the device.
