Detailed description of the invention
With reference to the accompanying drawings the air purifier that this utility model provides is described in detail.
The air purifier of Fig. 2 for providing in this utility model embodiment, be furnished with intake air way 2.1 and air outlet 2.8 at shell 2.7, arrange initial filter screen 2.2, fan 2.3, the LED ultraviolet LED 2.4 be oppositely arranged and nano photo-catalytic film 2.5 and secondary filter screen 2.6 in shell 2.7 inside successively from intake air way to air outlet.In this Burdick lamp, LED ultraviolet LED array 2.4 is radiated on nano photo-catalytic film 2.5, makes it produce catalytic degradation function.
As a kind of preferred implementation, nano photo-catalytic film can be arranged in secondary filter screen, make nano photo-catalytic film become wherein one deck of secondary filter screen.Secondary filter screen can be multistorey strainer mesh, and such as, the HEPA filter screen conventional with this area is identical, to strengthen filter effect.Because the function of photocatalyst and active carbon net overlaps, so also active carbon net can be removed, and only use photocatalyst film and HEPA filter screen.Although only show HEPA filter screen in figure as secondary filter screen 2.6, preferably, the secondary filter screen of the air purifier in this utility model still can include active carbon filter screen.
As optimal way, the LED ultraviolet LED array used in the present embodiment can use single light emitting diode, also can use multiple light emitting diode or be made up of array to use multiple light emitting diode.When using multiple light emitting diode, various shape can also be formed and use, coordinating the air purifier of various different profile and structure.
In addition, when using the combination of multiple LED ultraviolet LED, the direction of illumination of each light emitting diode can according to specific needs, be arranged to identical or different.Light emitting diode can be low power, also can be powerful.And in whole light emitting diode matrix, the single power of low power light emitting diode can be identical, also can not be identical.
Owing to using LED light emitting diode, so lower than prior art of the running voltage of air purifier that provides of this utility model, such as, 12V.So air purifier of the present utility model can work under the state be perfectly safe.
Especially, the LED ultraviolet LED in the present embodiment can select ultraviolet various frequency or various wavelength according to actual needs.In order to not produce ozone, usually the emission wavelength of LED ultraviolet LED is controlled between 365nm to 400nm.Meanwhile, activation effect can adopt the intensity of illumination strengthening unit are to make up.Such as, preferably, select wavelength to be the LED ultraviolet LED of 385nm spectrum, purify air while complete or almost completely free ozone can be accomplished.
Number of diodes, the power of diode array change according to the size of ventilation, and spectral wavelength also configures as required.
As mentioned above, going out same hydrargyrum quartz burner must high voltage power supply excite, and this shortcoming cannot overcome.But LED ultraviolet diode only needs the DC voltage of 3.2-3.8V just can driving LED light emitting diode emitting ultraviolet light.
List the various parameters of LED ultraviolet diode as an example below in form, other parameters can be used according to demand in actual applications.
Table 1
Owing to employing LED ultraviolet LED as light source, so compared with the air purifier of prior art, air purifier of the present utility model more easily manufactures, and structure is simple, volume is little, reliability is high, safety is good, the life-span is long, energy-conservation and especially do not produce ozone.
The volume of the air purifier provided due to this utility model is less, the air-purifier designs that this utility model provides can be become desktop type, vehicle-mounted type or desk lamp type air purifier, such as primarily of fan, LED ultraviolet LED battle array, nano-titania photocatalyst film and HEPA drainage screen are formed.
Be understandable that, on the basis not departing from above spirit of the present utility model, those skilled in the art can also make multiple improvement to this utility model.The diminutive volume that the air purifier provided by this utility model can realize, can change the profile of above-mentioned air purifier and structure, such as, be designed to the small size air cleaner etc. being suitable for using on vehicle.
Because ultraviolet radiation photocatalyst can make photocatalyst have the ability of extremely strong kill bacteria and virus, so have effect of obvious decomposing formaldehyde and smog as the air purifier of light source using ultraviolet, again in conjunction with HEPA drainage screen, the granule of PM2.5 mono-class can be filtered further.
