Background technology

Air is the essential condition that biology is depended on for existence, and the air cleaning in the human habitat more and more comes into one's own.Bad room air increases the weight of the many added burdens of human immune system, causes the muscle power consume, reduces the productivity and work efficiency.Breathe and disease of immune system for having among child, the adult, as asthma, emphysema and people hypersensitive, the high-risk factor that bad IAQ (indoor air quality) is fallen ill especially.According to investigation, at present in state-owned nearly 400,000,000 2 thousand ten thousand people suffer from asthma and allergic rhinitis, bad IAQ (indoor air quality) is a main cause.

Existing indoor air-purification device kind is more, roughly have: filter, adsorb, adopt that fan forced ventilation, electrostatic precipitation formula, magnetization are handled etc., every kind of method all has characteristics separately, does not see the indoor air cleaner that air purification methods such as active carbon airstrainer, far ultraviolet rays lamp, photocatalyst air purifying net, anion generator are integrated as yet.

Summary of the invention

It is a kind of with multiple air purification method reasonable combination such as activated charcoal strainer, far ultraviolet rays lamp, photocatalyst air purifying net, anion generators that the purpose of this utility model just is to provide, and reaches room air is carried out the purpose that multiple function purifies.

This utility model is realized in the following manner, housing 1 surface is provided with activated charcoal strainer replacement port 10, the state that is equipped with shows display lamp 8, far ultraviolet rays relay indicating light 2, wind speed adjusting turn-knob 6, from air inlet 7 activated charcoal strainer 11 inwardly is housed successively in the housing 1, far ultraviolet rays lamp 19, photocatalyst air purifying net 18, anion generator 17, and be fixed on by screw on the inner bottom surface of housing 1, left end is equipped with and detects control circuit 14; Housing 1 right-hand member is provided with external humidifier control interface 4, is installed with wind speed detecting sensor 12 humidity sensors 13 between air inlet 7 and activated charcoal strainer 11 side by side.

This utility model is compared with prior art can be harmful to airborne dust, pathogenic bacteria, hydrocarbons, nitrogen oxide, aldehydes, benzene class etc., and toxic gas purifies.Have multiple purifying functions such as powerful dedusting, sterilization, sterilization, can reach comprehensive, high efficiency, multi-functional effect, purify thoroughly, secondary pollution can not take place, and make with fresh air the purification of all contaminations in the room air.

1. housing, 2. ultraviolet relay indicating light, 3. power line, 4. humidifier control interface, 5. keyboard, 6. wind speed is regulated turn-knob, 7. air inlet, 8. state shows display lamp, 9. display, 10. activated charcoal strainer replacement port, 11. activated charcoal strainer, 12. air velocity transducers, 13. humidity sensor, 14. detect control circuit, 15. air outlets, 16. exhaust fan, 17. anion generators, 18. photocatalyst air purifying nets, 19. far ultraviolet rays lamps.

The specific embodiment

Below in conjunction with drawings and Examples this utility model is further specified.

When carrying out air cleaning, be that the air that needs purify is imported in this depurator the exhaust fan 16 of its power resources in air outlet 15 by air inlet with this device; Enter the air of depurator inside, at first by removable active carbon airstrainer 11, utilize the hole of active carbon airstrainer 11 to show dual absorption, characteristics that the material adsorption capacity is big, with deleterious particle things such as the airborne dust of filtering, smog, stink, abnormal flavour, toluene, methanol, antibacterials.Active carbon airstrainer 11 can be changed at any time by activated charcoal strainer replacement port 10.

Air through active carbon airstrainer 11, arrive far ultraviolet rays lamp 19 irradiation areas, far ultraviolet rays lamp 19 uses the strong far ultraviolet rays wave band of sterilizing ability, by the irradiation of ultraviolet to microorganism, with the organizational structure (DNA-nucleic acid) of change and destroy microorganisms, cause the nucleic acid structure sudden change, the organism forfeiture is duplicated, fertility, function wrecks, thereby reaches sterilization, germ-resistant purpose.

Through the air behind far ultraviolet rays lamp 19 irradiated regions, arrive photocatalyst air purifying net 18, filtered air once more, directly with airborne organic pollution, be completely oxidized to nontoxic material, to some Organic substance such as chloroform, tetrachloro charcoal, Perchlorobenzene, can both be decomposed effectively, photocatalyst is all effective to the numerous Organic substances of the kind from the hydrocarbon to the carboxylic acid, even atom Organic substance such as halogenated hydrocarbons, dyestuff, itrogenous organic substance, organophosphorus insecticide are also had good effect of removing, generally can reach complete purification effects through sustained response.

For making the with fresh air of output, added anion generator 17 in the device, anion generator 17 produces high pressure and makes air ionization, produces anion, utilizes anion to adsorb dust, kill bacteria.
