[0038] The two snap-fit ​​caps 26 are snap-fitted to the top of the one-way air core 1 7 and the one-way air core 2 8 respectively, and the tops of the one-way air core 1 7 and the one-way air core 2 8 are protected by the two snap-fit ​​caps 26, while blocking the one-way air core 2 8 to prevent the airbag 4 from being deflated.

[0039] Reference Figure 5 - Figure 7 A rotating cover 11 is arranged inside the sealing disk 1, and a mesh frame 12 is arranged inside the blocking tube 2. A threaded opening 13 is opened at the bottom of the rotating cover 11, and a threaded ring 14 is opened on the outer wall of the top of the mesh frame 12. The threaded ring 14 is threadedly connected inside the threaded opening 13. A hinge 18 is fixedly connected to the left side of the top of the sealing disk 1, and a flip cover 17 is rotatably connected to the right side of the hinge 18. The flip cover 17 rests on the top of the rotating cover 11, and a slider 19 is slidably connected to the right side of the top of the flip cover 17. A connecting block 21 is fixedly connected to the bottom of the slider 19, a spring 23 is fixedly connected to the left side of the connecting block 21, and a clamping rod 22 is fixedly connected to the right side of the connecting block 21. A clamping groove 20 is opened on the right side of the inner wall of the sealing disk 1, and the clamping rod 22 is clamped in the inside of the clamping groove 20. The outer wall of the blocking tube 2 is opened with evenly distributed through holes 25, and a plurality of accommodating grooves 3 are arranged between the plurality of through holes 25. A groove 24 is opened on the left side of the rotating cover 11, and the inside of the groove 24 is larger than the hinge 18.

[0040] Put the desiccant and deodorant into the mesh frame 12, and then rotate the thread ring 14 into the threaded opening 13 to complete the installation of the rotating cover 11 and the mesh frame 12 and seal the desiccant and deodorant in the mesh frame 12. Push the slider 19 to the left to move the connecting block 21 to the right in the flip cover 17. At this time, the engaging rod 22 will leave the engaging groove 20. Then, rotate the flip cover 17 upward through the hinge 18 to open the sealing disk 1. At this time, the mesh frame 12 can be placed in the sealing tube 2 through the sealing disk 1, and then the flip cover 17 can be opened. The rotating cover 17 rotates downward through the hinge 18 to close the sealing disk 1, and the slider 19 is released to make the spring 23 rebound to the right, and the engaging rod 22 is driven by the connecting block 21 to engage into the engaging groove 20 to prevent the rotating cover 11 and the mesh frame 12 from being separated. The water vapor and odor in the reserved hole of the building are communicated with the sealing tube 2 through multiple through holes 25, and are removed through the desiccant and deodorant in the mesh frame 12. When the rotating cover 11 enters the sealing disk 1, the groove 24 prevents the rotating cover 11 from hitting the hinge 18.

[0041] Reference Figure 4 and Fig. 9 The bottom of the inner wall of the sealing disk 1 is fixedly connected with uniformly distributed springs 15 , and the tops of the multiple springs 15 are fixedly connected with buffer plates 16 , and the screen frame 12 rests on the top of the buffer plates 16 .

[0042] When the screen frame 12 enters the sealing tube 2, it will press against the buffer plate 16 and be buffered by multiple springs 15 to avoid collision caused by sliding too fast. Multiple springs 15 rebound the screen frame 12 through the buffer plate 16, and the flip cover 17 presses against the rotating cover 11 to prevent the screen frame 12 from being rebounded and pushed out. When it needs to be taken out, the flip cover 17 is rotated upward through the hinge 18. At this time, the buffer plate 16 pushes the screen frame 12 outward through the rebound of multiple springs 15, and the rotating cover 11 will be pushed out of the sealing disk 1, and then the rotating cover 11 can be taken out together with the screen frame 12.

[0043] Working principle: When in use, the mesh frame 12 filled with desiccant and deodorant is threadedly rotated into the threaded opening 13 through the threaded ring 14 to complete the installation of the rotating cover 11 and the mesh frame 12 to prevent the desiccant and deodorant from being separated, and the slider 19 is slid to the left to make the connecting block 21 move to the right in the flip cover 17, driving the locking rod 22 to leave the locking groove 20 to the left, and then the flip cover 17 is rotated upward through the hinge 18 to open the sealing disk 1, and then the mesh frame 12 is placed into the blocking tube 2 through the sealing disk 1. After being placed, the flip cover 17 is rotated downward and the slider 19 is released. At this time, the spring 23 will rebound to make the connecting block 21 push the locking rod 22 to the right to lock into the locking groove 20 for fixing, and the mesh frame 12 is blocked in the blocking tube 2. To avoid detachment, the blocking tube 2 is inserted into the reserved hole in the building, and then air is inflated into the one-way air core 7 and evenly distributed to all the air bags 4 through multiple interconnecting tubes 5 to make them all expand, and the blocking tube 2 is pressed against the inner wall of the reserved hole to seal the hole, while the sealing disk 1 blocks the outside of the hole to prevent debris from entering, and the moisture and odor in the reserved hole in the building are communicated with the inside of the blocking tube 2 through multiple through holes 25, so that the desiccant and deodorant in the mesh frame 12 can be removed, and when it needs to be removed, it is deflated through the one-way air core 2 8. At this time, the multiple interconnecting tubes 5 will drive all the air bags 4 to deflate together to make them shrink, and after shrinking, they will no longer press against the inner wall of the reserved hole in the building, and then the blocking tube 2 is pulled out of the reserved hole through the sealing disk 1 for next use.
