During utility model works, control circuit plate 815 controls water pump, fan works simultaneously, and the water in water storage case is pumped into filter by water pump, and pure water after filtering forms cascade from the ejection of water spray plate level.
Fan is by air suction cabinet, air flows along air inlet deflector, it is heated up through radiation aluminium seat, Brownian movement aggravates, then the air heated up flows to the space above water storage case along wind deflector, and from bottom to top through described cascade, air partial particulate thing in cascade air is taken away by cascade and falls in water storage case.
The condensation aluminum seat that filtered air then flows to above semiconductor chilling plate through water fender is put, and air is condensed into aqueous water through the steam that cascade carries and is back in water storage case.
Control circuit plate controls Wastewater by Electric magnet valve and opens by phased manner, will enter in waste water box with more polymictic sewage in filter.
Due to water filtration through filter before water spray plate sprays, dirt in water will not enter water spray plate and result in blockage water jet, so width of water jet can be designed to less, the density of water jet can arrange bigger, the contact area of air and cascade can be increased, strengthen the clean-up effect to air.
This utility model not only make use of semiconductor chilling plate to dehumidify filtered air, and unfiltered air is heated by the heat that make use of semiconductor chilling plate to produce, the Brownian movement of aggravation air, so air is more with contacting of cascade through cascade, enhances air purification effect.
Owing to filter is only for filtering the particulate contaminant in water, the filtering requirement comparing drinking water is much lower, therefore the ceramic element that described ceramic element compares Prinking water filter has bigger aperture, and filtration flow-rate is relatively big, decreases the load of water pump, has saved the energy.
