Description

A kind of air freshener

Technical field

The utility model relates to a kind of air cleaning unit, is specifically related to a kind of air freshener.

Background technology

Air freshener is also known as " air cleaner ", air cleaner, clarifier, refer to and can adsorb, decompose or transform various air pollutants (generally comprising the finishing pollution of PM2.5, dust, pollen, peculiar smell, formaldehyde and so on, bacterium, anaphylactogen etc.), effectively improve the product of air cleanliness.There are multiple different technology and medium in air purifier, enable it provide air that is clean and safety to user.Conventional air purifying process has: adsorption technology, negative (just) ion technology, catalysis technique, photocatalyst technology, superstructure light mineralising technology, HEPA high efficiency filter technology, electrostatic precipitation technology etc.; Material technology mainly contains: the efficient material of photocatalyst, active carbon, synthetic fibers, HEAP, anion generator etc.Existing air purifier is adopted as compound more, namely have employed multiple purification techniques and material medium simultaneously.Air freshener at home, medical treatment, industrial circle all have application, the field main product that is market with the Household Air Purifier of unit class at home.Topmost function removes the particle in air, comprises anaphylactogen, indoor PM2.5 etc., can also solve volatile organic matter air pollution problems inherent in the indoor because finishing or other reasons cause, the underground space, car simultaneously.Because the release of the space Air Contamination thing of relative closure has persistence and probabilistic feature, therefore using air purifier to purify the air of a room is one of internationally recognized method improving IAQ.In recent years, PM2.5 wins success quickly rapidly one of popular vocabulary becoming resident's air quality monitoring, and PM2.5 is also known as fine particle, particulate, fine grained, and fine particle refers to that in surrounding air, aerodynamics equivalent diameter is less than or equal to the particle of 2.5 microns.It can be suspended in air the long period, and content concn is higher in atmosphere for it, just represents air pollution more serious.Although PM2.5 is the component that in earth atmosphere composition, content is little, it has important impact to air quality and visibility etc.Compared with thicker Atmospheric particulates, PM2.5 particle diameter is little, and area is large, active strong, easily attach poisonous and harmful substances (such as, heavy metal, microorganism etc.), and the time of staying is in an atmosphere grown, fed distance is far away, thus larger on the impact of health and atmosphere quality.It is reported, " global environment prospect 5 " that United Nations Environment Programme in 2012 announces is pointed out, has 700,000 people to die from respiratory disease because ozone causes every year, has the premature death case of nearly 2,000,000 relevant with Particulate Pollution." institute of NAS periodical " (PNAS) has also delivered research report, claims in report, and the average life span of the mankind is because air pollution has probably shortened 5 years half.The report that the World Bank issues shows, the premature death number caused by outdoor air pollution, average out to people's every day 1000, has the people of 35 to 40 ten thousand to be faced with death every year.Specifically, as far back as 1997, the World Bank with regard to pre-in respect of 50,000 Chinese because air pollution and premature death.On the whole, the report of this part finds, the air pollution of China makes the life-span of city dweller decrease 18 years.Chinese invention patent ZL201210220667.3 discloses a kind of air purification and freshing device, imports air, carry out catharsis simultaneously with control circui ozone generator and anion generator to air by air blast air blast; Although its effect is pretty good, use multiple supply apparatus to purify air, energy loss is excessive simultaneously, the energy is not saved, also uneconomical in practice, set up energy conservation type with China, environmentally friendly state basic policy is not inconsistent, thus, need a kind of air freshener badly.
