Description
Technical field
The present invention relates to technical field of air purification, be specifically related to a kind of fan with purification function.
Background technique
At present, along with expanding economy, domestic big city haze weather gets more and more, and along with increasing of haze weather, the quality of indoor air also declines thereupon.
Haze, also claims the particle such as dust, sulfuric acid, nitric acid, organic hydrocarbon compounds in gray haze (smog) air that air also can be made muddy.The horizontal visibility of object is called mist or mist (Mist) in this phenomenon of 1000-10000 rice.Formed mist time atmospheric moisture should be saturated (when existing if any a large amount of nucleus of condensation, relative moisture not necessarily reach 100% just may occur saturated).Due to the mist scattering of liquid water or ice crystal composition light and wavelength relationship not quite, thus mist seems to be creamy white or bluishwhite and grey.Sulfur dioxide, nitrogen oxide and pellet are the main compositions of haze.
The harm that haze produces human body is as follows:
(1) on the impact of respiratory system
The constituent of haze is very complicated, comprises hundreds of Atmospheric Chemistry particulate matter.The particulate that the mainly diameter be wherein harmful to health is less than 10 microns, as mineral grain thing, sea salt, sulphate, nitrate, Organic aerosol particle, fuel and automobile exhaust gas etc., it directly can enter and stick in human respiratory tract and alveolar.Especially submicron particle can be deposited in upper and lower respiratory tract and alveolar respectively, causes the illness such as acute rhinitis and acute bronchitis.For chronic respiratory disease patients such as bronchial astehma, chronic bronchitis, obstructive emphysema and COPDs, haze weather can make state of an illness acute attack or acute exacerbation.If be in this environment for a long time also can bring out lung cancer.
(2) on the impact of cardiovascular system
Haze sky is also very serious on the impact of human body cardiovascular and cerebrovascular disease, normal blood circulation can be hindered, cause cardiovascular disease, hypertension, coronary heart disease, cerebral hemorrhage, angina pectoris, miocardial infarction, heart failure etc. may be brought out, 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 extent.On the one hand often temperature is lower the greasy weather again, and some hypertension, patients with coronary heart disease go to suddenly cold outdoor from warm indoor, blood vessel expands with heat and contract with cold, and blood pressure also can be made to raise, cause the generation of apoplexy, myocardial infarction.The careful reply so heart and brain blood disease-sufferer must take medicine on time.
(3) haze weather also can cause that surface layer is ultraviolet to be weakened, and make the increased activity of the infectiousness germ in air, infectious diseases increases.
(4) child growth is unfavorable for.Because sunshine in greasy weather reduces, children's Ultraviolet radiation is not enough, and in body, vitamin D generates not enough, greatly reduces, serious meeting causes Infant Rickets, children growth slows down to the absorption of calcium.
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, thus cause distributing various organic pollutant to indoor, the such as material such as formaldehyde, benzene.
At present, for the process of these indoor pollutants, be mostly to adopt various air cleaner and active carbon adsorption etc., but the increase of these equipment, coverage can be taken, thus increase cost.
Existing fan, is only used to rotary air, brings the circulation of air, and the fan of market does not have 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 catalysis is carried out to air, by the harmful matter in air, such as nitrogen oxide, oxycarbide, organic odor contamination such as benzene,toluene,xylene, ethylbenzene, vinyl benzene, formaldehyde, acetaldehyde, acrylaldehyde etc., carry out decomposing, being oxidized or/and adsorb, bactericidal purifying is carried out to air, ensure indoor air cleaning.
For reaching this object, the present invention by the following technical solutions:
A kind of fan with purification function; it filtration, purification unit comprising driver element, flabellum, front safety cover, rear safety cover and be fitted in front safety cover; drive unit drives flabellum rotates; driver element, flabellum are arranged in the space that front safety cover and rear safety cover form; flabellum drives the process of air through described filtration, purification unit of circulation, the first adsorption element superposed before and after described filtration, purification unit comprises, catalytic member and the second adsorption element.
