[0039] More specifically, when it is necessary to wrap the rubber sleeve 20 around the outside of the ear-hanging rope 4 and connect the ear-hanging rope 4 to the mask body 1, first rotate the rotating plate 10, the rotating plate 10 will drive the movable block 15 to move, and then the movable block 15 will cooperate with the fixed block 17 to compress the spring 18. When the spring 18 is compressed to the limit, the position of the positioning hole 16 corresponds to the position of the limiting rod 12, and then rotate the control sleeve 11, the side wall of the limiting groove 14 opened on one side of the control sleeve 11 will squeeze the side wall of the limiting rod 12, so that the limiting rod 12 moves from The limiting groove 14 slides into the annular groove 25, and then one end of the limiting rod 12 passes through the giving hole 16 provided on the rotating plate 10, and squeezes the push spring 13 sleeved on the outside, and then the control sleeve 11 is rotated. Since the top sleeve 19 and the control sleeve 11 are movably connected through threads, and the arrangement of the matching block 23 and the matching groove 24 forms a limit for the top sleeve 19, then the top sleeve 19 will slide along the control sleeve 11, and at the same time the control sleeve 11 will push the sliding block 9 to move, and then the sliding block 9 will drive the slider 7 along the slide groove 6 slides, due to the unique inclined structure of the slide groove 6, the sliding block 9 will gather inwards at the same time during the sliding process, and the sliding block 9 will drive the matching block 23 to slide in the matching groove 24, and then the rubber sleeve 20 and the ear hanging rope 4 are inserted into the inner side of the fixed sleeve 8, and then the clamping plate 21 will clamp the rubber sleeve 20 and the ear hanging rope 4, and then continue to rotate the control sleeve 11, and then the conical spring 22 set on one side of the clamping plate 21 will be compressed, so that the clamping plate 21 clamps the rubber sleeve 20 and the ear hanging rope 4 more tightly, and then stop rotating the control sleeve 11. The control sleeve 11 and the push spring 13 will push the limit rod 12 to engage in the corresponding limit groove 14, and then the rotating plate 10 will be released to make the spring 18 reset, and then the spring 18 will push the movable block 15 to drive the rotating plate 10 to reset, and then the position of the limit rod 12 and the yield hole 16 will no longer correspond. This structure can wrap rubber sleeves 20 of different thicknesses around the outside of the ear hanging rope 4 for fixation according to the needs of different people, and at the same time, the extending length of the ear hanging rope 4 and the rubber sleeve 20 can be flexibly adjusted according to the above operation, which is more convenient to use.

[0040] In summary, when the overall device is in use or running: when the device is used daily, the mask 1 is hung on the ear through the ear rope 4, and the rubber sleeve 20 wrapped around the outside of the ear rope 4 can effectively prevent the ear rope 4 from directly strangling the ear. The setting of the filter 2 can filter the air entering the vent 5. After long-term use, the user can remove the filter 2 directly from the vent 5 for replacement, or maintain and clean the filter plate 3 set in the filter 2, and then use it again, effectively avoiding waste of resources.

[0041] When it is necessary to wrap the rubber sleeve 20 around the outside of the ear-hanging rope 4 and connect the ear-hanging rope 4 to the mask 1 body, first rotate the rotating plate 10, the rotating plate 10 will drive the movable block 15 to move, and then the movable block 15 will cooperate with the fixed block 17 to compress the spring 18. When the spring 18 is compressed to the limit, the position of the hole 16 corresponds to the position of the limit rod 12, and then rotate the control sleeve 11, the side wall of the limit groove 14 opened on one side of the control sleeve 11 will squeeze the side wall of the limit rod 12, so that the limit rod 12 moves out of the limit groove 1 4 slides into the annular groove 25, and then one end of the limiting rod 12 passes through the clearance hole 16 opened on the rotating plate 10, and squeezes the push spring 13 set on the outer side, and then rotates the control sleeve 11. Since the top sleeve 19 and the control sleeve 11 are movably connected through threads, and the arrangement of the matching block 23 and the matching groove 24 forms a limit for the top sleeve 19, then the top sleeve 19 will slide along the control sleeve 11, and at the same time, the control sleeve 11 will push the sliding block 9 to move, and then the sliding block 9 will drive the slider 7 to move along the slide groove 6. Sliding, due to the unique inclined structure of the slide groove 6, the sliding block 9 will gather inwards at the same time during the sliding process, and the sliding block 9 will drive the matching block 23 to slide in the matching groove 24, and then the rubber sleeve 20 and the ear hanging rope 4 will be inserted into the inner side of the fixed sleeve 8, and then the card plate 21 will clamp the rubber sleeve 20 and the ear hanging rope 4, and then continue to rotate the control sleeve 11, and then the conical spring 22 set on one side of the card plate 21 will be compressed, so that the card plate 21 clamps the rubber sleeve 20 and the ear hanging rope 4 more tightly, and then stop rotating the control sleeve 11. The sleeve 11, the push spring 13 will push the limit rod 12 to engage in the corresponding limit groove 14, and then the rotating plate 10 is released to make the spring 18 reset, and then the spring 18 will push the movable block 15 to drive the rotating plate 10 to reset, and then the position of the limit rod 12 and the yield hole 16 no longer corresponds. This structure can wrap rubber sleeves 20 of different thicknesses around the outside of the ear hanging rope 4 for fixation according to the needs of different people, and at the same time, the extending length of the ear hanging rope 4 and the rubber sleeve 20 can be flexibly adjusted according to the above operation, which is more convenient to use.
