Porcelain particle 13-1 can high-temperature heating treatment, cavernous body 13-2 washable processing recycles, no replacement is required after processing.Exist simultaneously
Hydroponic plant is planted in drainage trap 13, for organic matter and inorganic salts in absorption cycle water, the above measure ensures air
The long-term effectiveness of purification.
The present invention realizes air-filtering process are as follows: air pump 2 passes through 4 input air filter 1 of tracheae after compressing air
Exhaust pipe 16, compressed air is discharged by 16 upper end gas vent 16-1 of exhaust pipe, because by middle part water storage container 15, water drenching strainer
12, the surrounded formation in the top surface back pool 11-1 and the bottom surface of drainage trap 13 is a closed space, into compression therein
Air can only be discharged via water drenching strainer 12；Air is after the filtering of water drenching strainer 12 using the netted venthole of 11 upper end of shell
11-2 is discharged into interior；
Realizing the process of water circulation is: water pump 18 extracts the water of the bottom back pool 11-1, passes through outlet pipe 18-1 after pressurization
Nozzle sprays upwards forms fountain, and water is fallen after rise in wide-mouth injector 14, and the water of wide-mouth injector 14 is spilt into drainage trap 13,
Flowed at the top of water drenching strainer by ceramic particle 13-1 and the filtered water of cavernous body 13-2 by gravity and by gravity along
Water drenching strainer collects downwards Huis pond 11-1 and completes water circulation；Ultraviolet lamp 19 in back pool 11-1 completes water and disappears clearly；
Due to polluting air after air pump compresses by being filtered water screen mistake after decompression in tracheae input air filter
Filter is discharged finally by shell gas vent, therefore air pump can be installed on to outdoor, air cleaner use disposed within, at this time gas
Outdoor air transtracheal input air filter is purified heel row through it and enters interior by pump, and then can be further decreased interior and be made an uproar
Sound.In conjunction with fountain design and green implanting meter, makes device on the basis of humidifying to indoor air purification, reduce visual pollution, beauty
Environment is changed.
