Son, such as mineral grain thing, sea salt, sulfate, nitrate, Organic aerosol particle, fuel and automobile exhaust gas, these aerosols
Particle can be directly entered and be adhered in human respiratory tract and alveolar, especially submicron particle, can be deposited on upper and lower
In respiratory tract and alveolar, cause the illnesss such as acute rhinitis and acute bronchitis.For bronchial asthma, chronic bronchitis,
The patient of the chronic respiratory diseases such as obstructive emphysema and Chronic Obstructive Pulmonary Disease, haze weather can make the acute hair of the state of an illness
Work or acute exacerbation.
Indoor fresh air air cleaner is one of the effective means for preventing haze from encroaching on.But indoor fresh air currently on the market
It the shortcomings that air cleaner product, generally existing has a single function, less effective, is mainly shown as：
When existing indoor air purifier work, only the sealing and circulating of room air, cannot introduce outdoor fresh air,
And if the ventilation that opens a window, and indoor air quality can be caused to decline, clean-up effect cannot be kept, and existing many fresh air air are net
Change machine, simple filtration solid suspension can not eliminate the sour gas pollutant in air.The heating season in the north, indoor mistake
In drying, and existing fresh air air cleaner cannot provide moisturization effect, and human body natural has the sense of discomfort.
The invention of the present inventor《A kind of household fresh air rinse air clarifier》(patent No. 201520234508.8), tool
There is excellent fresh air air purification effect, but since the product is in fresh air air purification process, required wind pressure, air quantity are more than general

Line；Impeller 5 is constituted by upper and lower two circular ring shape faces and vertically in multiple radial air blades 11 of upper and lower two annulus faces,
The annular surface of upper disk 7 is plane, there is the gap of air circulation between the radial blade of radial equipartition.Motor 6 is in axis
Line lower part, 6 impeller 5 of motor rotation in spiral case 1, the air come in is centrifuged and is pressurizeed.
When traditional centrifugal blower work, impeller 5 rotates under the drive of motor 6, and centrifugal force makes air from a-quadrant to B
Region is flowed, and realizes the purpose of conveying air.The opening of spiral case 1 is higher than 5 air inlet of impeller, and distance is big between impeller 5 and spiral case 1,
Air pressure close to the 5 inside regions C of impeller is equal with 5 outside B area of impeller, hence it is evident that it is higher than 5 inside air pressure of impeller, it is empty
Gas has the trend (being referred to as air return) flowed from C to A, and wind turbine efficiency is caused to decline.The effect of air-ducting ring 2 is to prevent air
Regurgitant volume, to keep higher performance, but since the pressure difference of C and A is equal to the total wind pressure of wind turbine, the gap between air-ducting ring 2 and impeller 5
There are big pressure difference, the return airs of high flow rate, so as to cause apparent airflow noise --- it is applicant's understanding that this is that common centrifugation is logical
The maximum noise source of wind turbine.
