Description
Technical field
The utility model relates to demonstration teaching aid, particularly a kind of air purifier demonstration teaching aid.
Background technology
2013, " haze " became annual keyword.In the January of this year, 4 times haze process shrouds 30 provinces (district, city), and in Beijing, only having 5 days is not haze sky.Have report display, in 500 cities of Largest In China, only reach the air quality standard of world health organisation recommendations less than the city of 1%, meanwhile, polluting 10 the most serious cities in the world has 7 in China.Haze is the portmanteau word of mist and haze.The globule trickle in air is mist, and tiny particle is haze.Haze is molecular by grains such as the dust in air, sulfuric acid, nitric acid, organic hydrocarbon compounds.It also can make air muddy, and the visual field is fuzzy and cause visibility deterioration.
Fine particle is also known as particulate, fine grained, PM2.5, and fine particle refers to that in surrounding air, diameter is less than or equal to the particle (namely above-mentioned haze is) 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 residence time is in an atmosphere grown, fed distance is far away, thus larger on the impact of health and atmosphere quality.Fine particle is larger to the harm of health, because diameter is less, the position entering respiratory tract is darker.The particle of 10 μm of diameters is deposited on the upper respiratory tract usually, the be deep into bronchiole of less than 2 μm and alveolar.After fine particle enters human body to alveolar, directly affect the ventilatory function of lung, make body easily be in anaerobic condition, as seen all-pervasive, harm very large.
And just form good habits and customs from the little children of allowing, paying close attention to the air quality in the living environment of oneself, be extremely important is also necessary.But be limited to the function that existing demonstration teaching aid does not all have to carry out purification of air simulation mostly, so children lack the cognition to air purifier, if directly use air purifier in kind to carry out demonstrating and too danger, be also not suitable for children and understand its principle of work.
At present, air purifier demiware substantially only rests on simple video or picture introduction, cannot reach the effect increasing children's entity understanding, and the principle of work and power is too complicated for children simultaneously, and children are difficult to intuitivism apprehension.
