Upper end cover and bottom end cover are connected with noise reduction inner tube；Noise reduction outer tube top is equipped with the hemispherical head with spherical plate clearance fit；
It is equipped with plug between spherical plate and hemispherical plug, check valve is evenly equipped in plug；Spherical plate is formed with conical head top
Accommodation space in fill once quieter material；It is empty that noise reduction outer tube, upper end cover, bottom end cover and noise reduction inner tube are formed by receiving
Between in be filled with secondary quieter material；It is evenly equipped with stomata on spherical plate, upper end cover and bottom end cover.
Further, conical head, plug, hemispherical head and upper end cover collectively form secondary buffer room.
Further, spherical plate, hemispherical head and plug collectively form reversal chamber.
Further, spherical plate is to be detachably connected with conical head.
Further, upper end cover and bottom end cover are annular slab.
Further, hemispherical head and noise reduction outer tube are washable connection.
Further, conical head is equipped with air distribution plate with noise reduction inner tube junction, and stomata is evenly equipped on air distribution plate.
Further, conical head collectively forms a surge chamber with air distribution plate.
Compared with prior art, the beneficial effects of the utility model are as follows：Surge chamber there are two settings in the utility model,
Its speed can be reduced to air-flow into row buffering；It is provided with sound-absorbing process twice, enhances sound-absorbing effect；The multiple deceleration of layout designs
Sound-absorbing structure enhances the sound absorption qualities of the utility model.

Specific implementation mode
A kind of molecular sieve oxygen generation noise-reducing structure, as shown in Figure 1, including noise reduction inner tube 2,2 outside of noise reduction inner tube, which is arranged with, to disappear
Sound outer tube 4；The conical head 11 of top closure is connected on 2 top of noise reduction inner tube, conical head 11 is connect with noise reduction inner tube 2
The cross section of one end is less than the cross section of its one end far from noise reduction inner tube 2, and end of the conical head 11 far from noise reduction inner tube 2 connects
It is connected to spherical plate 8；It is evenly equipped with stomata on the top end face of conical head 11；Noise reduction outer tube 4 by upper end cover 12 and bottom end cover 1 with disappear
Sound inner tube 2 is connected；Upper end cover 12 and bottom end cover 1 are annular slab；4 top of noise reduction outer tube is equipped with and 8 clearance fit of spherical plate
Hemispherical head 6；It is equipped with plug 7 between spherical plate 8 and hemispherical plug 6, check valve, conical head are evenly equipped in plug 7
11, plug 7, hemispherical head 6 and upper end cover 12 collectively form secondary buffer room 5；Spherical plate 8, hemispherical head 6 and plug 7
Collectively form reversal chamber 10；Gap of the gas between spherical plate 8 and hemispherical head 6 enters secondary buffer room across check valve
In 5；Spherical plate 8 is formed by accommodation space with 11 top of conical head and fills once quieter material 9；Noise reduction outer tube 4, on
End cap 12, bottom end cover 1 and noise reduction inner tube 2, which are formed by accommodation space, is filled with secondary quieter material 3；Spherical plate 8, upper end cover
12 and bottom end cover 1 on be evenly equipped with stomata.
Spherical plate 8 is to be detachably connected with conical head 11, and hemispherical head 6 and noise reduction outer tube 4 are washable connection；Cone
The junction of shape end socket 11 and noise reduction inner tube 2 is equipped with air distribution plate 14, and stomata, conical head 11 and gas distribution are evenly equipped on air distribution plate 14
Plate 14 collectively forms a surge chamber 13.
When work, gas enters from noise reduction inner tube 2, enters a surge chamber 13 after passing through air distribution plate 14, then pass through taper
The stomata on 11 top of end socket enters in a sound-absorbing material 9, and is entered in reversal chamber 10 by the stomata in spherical plate 8, gas
