Description

A kind of air purifier

Technical field

The utility model relates to a kind of cleaning equipment, relate in particular to a kind of air purifier that simultaneously comprises fine particle measuring ability and music playback function.

Background technology

Along with the raising of people's income, the improvement of life, has higher requirement for interior decoration.Present stage, almost every household all will be fitted up indoor.Interior decoration presents complicated diversified development trend, new material, new technology etc. constantly occur, all can inevitably occur polluting indoor, and finishing pollution has now become the important pollution sources of resident living, how to remove room air pollution, solving the health problem that causes of air pollution becomes the hot issue that present stage is concerned about very much.

Under this demand, the air purifier with air-cleaning function is progressively capturing consumption market.In country's " air purifier " relevant criterion, air purifier is defined as to " equipment that separates and remove one or more pollutants from air " or " airborne pollutant being had to the device of certain removal ability ".Air purifier mainly solves indoor, the underground space, the in-vehicle air pollution problem that cause due to finishing or other reasons.Present stage, using air purifier to purify the air of a room is the internationally recognized method of improving IAQ.

In air purifier, there are multiple different technology and medium, according to the difference of technology and medium, conventional air purifying process has: the asymmetric plasma air purifying technology of low temperature, adsorption technology, anion technology, negative oxygen ion technology, molecular complex technology, photocatalyst technology, HEPA high efficiency filter technology, electrostatic high-frequency high-voltage dust removing sterilizing of new generation are except radon technology, active oxygen technology, room temperature catalytic oxidation formaldehyde and catalytically bactericidal process etc.; Material technology mainly contains: photocatalyst, active carbon, synthetic fibers, the efficient material of HEAP, anion generator etc.The existing air purifier in domestic market is adopted as compound more, has adopted multiple purification techniques and material medium simultaneously.

But an air purifying process often uncared-for factor is exactly fine particle.Fine particle claims again particulate, fine grained.In atmosphere, particle diameter is less than or equal to 2 μ m(sometimes with being less than 2.5 μ m, i.e. PM2.5) particle.Fine particle particle diameter is little, contains a large amount of poisonous and harmful substances, thereby larger on the impact of health.In February, 2012, State Council agrees to that " ambient air quality " of issuing new revision increased fine particle monitoring index.On February 28th, 2013, national scientific and technical terminology validation board claims PM2.5 to intend definite designation for " fine particle ".

Indoor, the dust that not only finishing produces is the main source of particle, and second-hand-cigarette is also the main source of particle.Particle can damage respiratory system and cardiovascular system, causes asthma, lung cancer, angiocardiopathy, inborn defect and dead too early.A research that is published in " JAMA " shows, PM2.5 can cause artery plaque deposition, causes vascular inflammation and atherosclerotic, finally causes heart disease or other cardiovascular problems.This starts from studies confirm that of nineteen eighty-two, when the concentration of PM2.5 in air is for a long time higher than 10 μ g/m3, the rising that will bring mortality risk.Every increase by the 10 μ g/m3 of concentration, total mortality risk can rise 4%, and the mortality risk that heart and lung diseases brings rises 6%, and the mortality risk that lung cancer is brought rises 8%.In addition, PM2.5 is organic pollution and the heavy metal such as absorbing multiring aromatic hydrocarbon very easily, and carcinogenic, teratogenesis, mutagenic probability are obviously raise.

Therefore, with PM2.5 measuring ability be the important development direction in present stage air purifier field.Meanwhile, the air purifier of present stage, is only simple air cleaning facility, lacks some amusement functions, therefore, increases amusement function, is to enrich air purifier kind, improves the important marketing methods of its sales volume.

Summary of the invention

In order to address the above problem, the utility model has designed a kind of air purifier that simultaneously comprises fine particle measuring ability and music playback function.Air-cleaning function be opened or be closed to this air purifier not only can automatically according to airborne fine particle content, can combine with the music of playing simultaneously, and air quality is pointed out and reported to the police.
