The distance between two adjacent second flexible balls 32 is equal to the outer diameter of the second flexible balls 32, so that the second flexible balls 32 in the second cavity 28 are distributed more closely, and the sound attenuation effect can be effectively enhanced.

The implementation mode is specifically as follows: when the air-inflated flexible ball is used, the air in the first cavity 15 of the first flexible ball 29 is adjusted to be partitioned by arranging the second cavity 28, the first flexible ball 29, the third cavity 30, the first through groove 31, the second flexible ball 32, the fourth cavity 33 and the second through groove 34, meanwhile, the first flexible ball 29 can enhance the supporting effect on the first cavity 15, the stability is good, the air enters the third cavity 30 through the first through groove 31 and then is exhausted from the other first through groove 31, the noise reduction effect is enhanced, the second cavity 28 is communicated with the first cavity 15, the air in the first cavity 15 enters the second cavity 28, the noise reduction effect of the outer layer 14 can be effectively enhanced, the air enters the second flexible ball 32 through the second through groove 34 and then is exhausted from the other second through groove 34, the second cavity 28 can be effectively inflated, and simultaneously, the second flexible ball 32 can flexibly support the second cavity 28, meanwhile, the first cavity 15 and the second cavity 28 can be filled with wind, so that the supporting tube 11 can be effectively clamped, and the stability of the flexible silencing sleeve 12 can be ensured without additionally arranging other clamping devices.

The working principle of the invention is as follows:

referring to the attached drawings 1-3 and 6 of the specification, by arranging an air inlet silencer 5 and an air outlet silencer 7, the air inlet silencer 5 can perform silencing treatment on an air inlet pipe 4 of the device, a support pipe 11 supports a flexible silencing sleeve 12, a first flexible spherical shell sleeve 16 and a second flexible spherical shell sleeve 17 are matched with each other, multiple silencing treatment on inlet air can be realized, outward diffusion of noise is effectively avoided, an air inlet path can be effectively guided by arranging through holes, the air inlet path is matched with the first flexible spherical shell sleeve 16 and the second flexible spherical shell sleeve 17 to work, further, the silencing treatment is effectively enhanced, multiple groups of third flexible spherical shell sleeves 24 perform multiple buffering treatment inside the first flexible spherical shell sleeve 16 and the second flexible spherical shell sleeve 17, the silencing treatment effect is further enhanced, multiple groups of fourth flexible spherical shell sleeves 26 perform blocking silencing treatment inside the third flexible spherical shell sleeves 24, a first cavity 15 performs buffering treatment outside the first flexible spherical shell sleeves 16 and the second flexible spherical shell sleeves 17, the silencing treatment effect can be further enhanced, the inner side and the outer side of the supporting pipe 11 can be effectively subjected to flexible silencing treatment, the noise generated by the contact of the air inlet pipe 4 and the air inlet silencer 5 with the water surface can be effectively reduced, and the normal life of residents around a water area is ensured;

further, referring to the specification, fig. 2 and fig. 4-6, by providing the second cavity 28, the first flexible ball 29, the third cavity 30, the first through groove 31, the second flexible ball 32, the fourth cavity 33 and the second through groove 34, the noise reduction effect of the inner layer 13 and the outer layer 14 can be effectively enhanced, the first flexible ball 29 partitions and supports the first cavity 15, the second flexible ball 32 flexibly supports the second cavity 28, and at the same time, the first cavity 15 and the second cavity 28 can be filled with wind, so that the support tube 11 can be effectively clamped, and the stability of the flexible noise reduction sleeve 12 can be ensured without additionally providing other clamping devices.
