[0027] Specifically, the rotating shaft 10 is rotated, and the rotation of the rotating shaft 10 drives the centrifugal circle 11 to rotate. After the centrifugal circle 11 rotates, it separates from the pressure block 8. After the centrifugal circle 11 separates from the pressure block 8, the pressure on the pressure block 8 is released, and the first spring 9 rebounds again. After the first spring 9 rebounds, it pushes the pressure block 8 to slide. When the pressure block 8 slides, it drives the sliding shaft 7 to slide inside the second slide groove 6. After the pressure block 8 slides, it pulls the strap 2 to slide to a suitable position inside the first slide groove 4 and then fixes the strap 2, thereby achieving the effect of adjusting the tightness of the strap 2.

[0028] Reference Figure 3-4 The dustproof assembly includes a shell 12, the outer wall of the shell 12 is arranged on the inner wall of the cover surface 1, and the inner wall of the shell 12 is fixedly connected with a dust cover 13; the outer wall of the sliding shaft 7 is slidably connected to the inside of the second slide groove 6, and one end of the first spring 9 is fixedly connected to the inner wall of the pressing block 8; the outer wall of the dustproof cover 13 is fixedly connected to the second spring 14, and one end of the second spring 14 is fixedly connected to a buckle 15; a third slide groove 16 is opened inside the buckle 15, and the outer wall of the second spring 14 is slidably connected to the inside of the third slide groove 16;

[0029] Specifically, the buckle 15 is pressed to move, the buckle 15 presses down the second spring 14 to compress it, and the second spring 14 slides inside the third sliding groove 16 .

[0030] Reference Figure 3-4 The outer wall of the housing 12 is provided with a cover 17, and a card slot 18 is provided inside the cover 17; the outer wall of the buckle 15 is provided inside the card slot 18; and a gripping groove 19 is provided inside the cover 17;

[0031] Specifically, after the cover 17 is installed on the outer wall of the shell 12, the buckle 15 is released, and the second spring 14 rebounds to push the buckle 15 to move into the interior of the slot 18. The cover 17 can be removed by pressing the buckle 15 again. The grab groove 19 makes it easy to take off the cover 17.

[0032] Working principle: When the device is needed, first rotate the shaft 10 on the inner wall of the elastic frame 3. The shaft 10 rotates. When the outer wall of the shaft 10 rotates on the inner wall of the elastic frame 3, the centrifugal circle 11 on its outer wall rotates. When the centrifugal circle 11 rotates inside the elastic frame 3, its outer wall separates from the outer wall of the pressing block 8. When the outer wall of the centrifugal circle 11 separates from the outer wall of the pressing block 8, the pressure on the pressing block 8 is released. When the pressure of the centrifugal circle 11 on the pressing block 8 is released, the first spring 9 inside it will When the first spring 9 rebounds, it pushes the pressing block 8 to slide. When the outer wall of the pressing block 8 slides on the inner wall of the supporting frame 5, it drives the sliding shaft 7 of its outer wall to slide. The outer wall of the sliding shaft 7 slides inside the second sliding groove 6. When the pressing block 8 slides, the elastic frame 3 is adjusted and pulled to make the outer wall of the strap 2 slide inside the first sliding groove 4. Finally, after the elastic frame 3 is adjusted to a suitable position, the rotating shaft 10 is rotated to fix the strap 2 inside the first sliding groove 4, so that the To adjust the tightness of the strap 2, when the dust cover 13 needs to be sealed, the buckle 15 is first pressed, and the buckle 15 moves. When the buckle 15 moves, the second spring 14 inside it is pressed down to be compressed. When the second spring 14 is pressed down, its outer wall slides inside the third slide groove 16. After the buckle 15 is pressed, the outer wall of the cover 17 is installed to the outer wall of the shell 12 and then the buckle 15 is released. When the buckle 15 is released, the second spring 14 rebounds. When the second spring 14 is When rebounding, the buckle 15 will be pushed to move. When the buckle 15 is pushed to move by the second spring 14, it will enter the inside of the slot 18. The buckle 15 can be pressed again to remove the cover 17. The grab groove 19 makes it easy to take the cover 17, so that not only can the strap 2 be adjusted according to the size of the ear, but also the dust cover 13 can be protected when the mask is not in use to extend the service life of the mask. Finally, the strap 2 can be worn on the ear more fixedly.
