Abstract

The invention discloses a fan with a purifying function. The fan comprises a driving unit, fan blades, a front protection cover, a rear protection cover and a filtering and purifying unit attached into the front protection cover. Circulating air is treated by the filtering and purifying unit. The filtering and purifying unit comprises a first adsorption component, a catalyst component and a second adsorption component which are stacked from front to back. The catalyst enables the removing rate of benzene, methylbenzene, dimethylbenzene, ethylbenzene, phenylethylene, formaldehyde, acetaldehyde and acraldehyde in the air in a building to reach 0.05 milligrams per cubic meter or below, and meanwhile the microorganism content in the circulating air is remarkably lowered.

Description

A kind of fan with purification function

Technical field

The present invention relates to air purifying process field, be specifically related to a kind of fan with purification function.

Background technology

At present, along with expanding economy, domestic big city haze weather is more and more, along with haze weatherIncrease, the quality of room air also declines thereupon.

Haze, also claims the grains such as the airborne dust of gray haze (smog), sulfuric acid, nitric acid, organic carbon hydrogen compoundSon also can make atmosphere muddiness. The horizontal visibility of object is called gently in this phenomenon of 1000-10000 riceMist or mist (Mist). While forming mist, atmospheric humidity should be saturated (while existence if any a large amount of nuclei of condensation, relativelyHumidity not necessarily reach 100% just may occur saturated). Due to the light of the mist scattering of aqueous water or ice crystal compositionLittle with wavelength relationship, thereby mist seems to be creamy white or Bluish white and grey. Sulfur dioxide, nitrogen oxidationThing and pellet are the chief components of haze.

The harm that haze produces human body is as follows:

(1) impact on respiratory system

The constituent of haze is very complicated, comprises hundreds of Atmospheric Chemistry particulate matters. The master of being wherein harmful to healthIf the particulate that diameter is less than 10 microns, as mineral grain thing, sea salt, sulfate, nitrate,Organic aerosol particle, fuel and automobile exhaust gas etc., it can directly enter and stick to human respiratory tract and lungIn bubble. Especially submicron particle can be deposited on respectively in upper and lower respiratory tract and alveolar, causes acute rhinitisWith illnesss such as acute bronchitis. For bronchial astehma, chronic bronchitis, obstructive emphysema and slowThe chronic respiratory disease patients such as property obstructive disease of lung, haze weather can make state of an illness acute attack or acuteIncrease the weight of. If also can bring out lung cancer in this environment for a long time.

(2) impact on cardiovascular system

Haze sky is also very serious on the impact of human body cardiovascular and cerebrovascular disease, can hinder normal blood circulation, leadsCause cardiovascular disease, hypertension, coronary heart disease, cerebral hemorrhage, may bring out angina pectoris, miocardial infarction, heart failureExhaust etc., make chronic bronchitis occur cor pulmonale etc.

In addition, thick fog weather pressure ratio is lower, and people can produce a kind of sensation of agitation, and blood pressure can increase naturally to some extentHigh. On the one hand often temperature is lower the greasy weather again, some hypertension, patients with coronary heart disease from warm indoor suddenlyGo to the outdoor of cold, blood vessel expands with heat and contract with cold, and also can make blood pressure raise, and causes sending out of apoplexy, myocardial infarctionRaw. The careful reply so heart and brain blood patient must take medicine on time.

(3) haze weather also can cause that surface layer is ultraviolet to be weakened, and makes the work of airborne infectiousness germProperty strengthens, and infectious disease increases.

(4) be unfavorable for child growth. Because reduce sunshine in greasy weather, children's ultraviolet ray underexposure, dimension in bodyRaw plain D generates not enough, and the absorption of calcium is greatly reduced, and serious meeting causes Infant Rickets, children growthSlow down.

Meanwhile, along with the raising of people's living standard, the interpolation of interior decoration, new furniture also significantly increases.But in interior decoration and furniture, inevitably use various glue or paint, thereby cause distributing indoorVarious organic pollutions, such as the material such as formaldehyde, benzene.

At present, for the processing of these indoor pollutants, be mostly to adopt various air purifiers and active carbonAbsorption etc., but the increase of these equipment can take careat, thus increase cost.

Existing fan, is only for rotary air, brings the circulation of air, the fan of market, noPossesses any purification function.

Summary of the invention

The object of the invention is to propose a kind of fan with purification function, it not only realizes the function of fan,Also air is carried out to catalysis, by airborne harmful substance, such as nitrogen oxide, oxycarbide, You JiqiTaste damage ratio, as benzene,toluene,xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde, methacrylaldehyde etc., carries outDecompose, be oxidized or/and absorption is carried out bactericidal purifying to air, ensure indoor air cleaning.

For reaching this object, the present invention by the following technical solutions:

With a fan for purification function, it comprise driver element, flabellum, front protective cover, rear protective cover withAnd being fitted in the filtration, purification unit in front protective cover, drive unit drives flabellum rotates, driver element, fanLeaf is arranged in the space of front protective cover and rear protective cover formation, and flabellum drives the air of circulation through described mistakeThe processing of filter clean unit, the first adsorption element, the catalytic portions of stack before and after described filtration, purification unit comprisesPart and the second adsorption element.

Described the first adsorption element is provided with fibrous filter layer, and described fibrous filter layer is superimposed with paper fiber thingFilter course and ultra-fine fibre glass thing filter course.
