50dB.In order to build comfortable quiet indoor environment, effectively removing the noise that air purifier generates just is particularly important.
Most of traditional noise abatement is all to use passive control methods (such as sqouynd absorption lowering noise, sound insulation and noise reducing), these
Method is with obvious effects for high frequency noise, but is not so good as active noise controlling for the effect of low frequency noise, and air purifier produces
Raw mainly low-frequency noise.For this low-frequency noise, if using traditional passive noise-reduction method, generally require additionally to set
Various noise elimination structures are counted, to occupy more spaces, passive noise reduction can only can just play reason to the noise of a certain frequency range in addition
The noise reduction thought, when environment changes or the noise properties of noise source itself change, under noise reduction meeting is apparent
Drop.

Specific implementation mode
The utility model is described in further detail in the following with reference to the drawings and specific embodiments, so that those skilled in the art
The utility model may be better understood and can be practiced, but illustrated embodiment is not as the restriction to the utility model.
Embodiment
Fig. 1 is referred to, the utility model discloses a kind of low-noise air gas purifiers, including clarifier ontology 3, are set to
Air-supply passage on clarifier ontology 3 and the wind turbine (not shown) being installed in air-supply passage, wherein in clarifier ontology 3
It is provided with filter core, humidification component etc., is filtered or is humidified when passing air through clarifier ontology 3.In order to facilitate the dimension in later stage
Shield and maintenance, it is preferred that air-supply passage is removably installed on clarifier ontology 3.In some embodiments, air-supply passage
The mode being permanently fixed can also be used to be installed on clarifier ontology 3.
Air-supply passage includes the first shell 1 of cylindrical structure, is used to install wind turbine in the first shell 1.Refer to figure
2, first shell 1 includes the first interlayer 11, the second interlayer 12 and third interlayer 13, the first interlayer 11 and second successively from inside to outside
The first cavity 14 is formed between interlayer 12, multiple first partitions 16 are set in first cavity 14, and first partition 16 is arranged so that
First cavity 14 is separated into multiple class triangular cavities 141；The second cavity 15 is formed between second interlayer 12 and third interlayer 13,
Multiple second partitions 17 are set in second cavity 15, and second partition 17 is arranged so that the second cavity 15 is separated into multiple fan annulars
Cavity 151.
In the operating condition, the noise that blower fan work is sent out sequentially enters class by the first interlayer 11 and the second interlayer 12
In triangular cavity 141 and fan toroidal cavity 151, after the multiple reflections of cavity, the energy part of sound wave is lost, portion
Divide and absorbed and cleared up by cavity, to reduce the noise of blower fan work, keeps the peace and quiet of indoor environment.
Since sound wave will pass through multiple reflections in the first cavity 14 and the second cavity 15, to which energy loss occur, because
This will ensure that the first cavity 14 and the second cavity 15 have certain thickness, but the thickness cannot be excessive, and crossing conference causes to blow
