Wherein, described light source comprises base, annular array evenly is arranged in the Transparent lamp shade that three LED lamp plates on described lamp socket and cover are established described three LED lamp plates centered by described filter center line, and the light-emitting area of described LED lamp plate is towards described active carbon layer.
Wherein, be strip on described LED lamp plate, the length of LED lamp plate is suitable with the height of described filter, is provided with along its length plurality of LEDs lamp pearl on described LED lamp plate.
Wherein, described active carbon layer comprises framework and screen cloth, and described framework is latticed and is covered the space that forms the described active carbon of loading by described screen cloth.
For solving the problems of the technologies described above, another technical scheme that the utility model adopts is: a kind of air purifier is provided, comprise housing, blower fan and air filter as above, described housing is provided with air inlet and air outlet, described blower fan and air filter are fixedly installed in housing, described air inlet forms air communication channel to described filter to described air outlet, and described blower fan is arranged in this air communication channel.
The beneficial effects of the utility model are: air filter of the present utility model, when air process filter, part air pollutants can be by charcoal absorption or by Filter paper filtering, thereby play the effect that purifies air, when light source igniting, illumination is at photocatalyst surface, photocatalyst can produce chemical reaction, produce strong catalytic degradation function, the toxic and harmful in air of effectively degrading, kill various bacteria, and the toxin that bacterium or fungi can be discharged decomposes and harmless treatment, but deodorizing anti-soil also simultaneously.Owing to having increased photocatalyst and corresponding light source, greatly improve the air purification effect of this air filter.
Description of drawings
Fig. 1 is the structural representation of the utility model air filter one embodiment.
Label declaration:
10, filter; 11, active carbon layer; 12, filter paper layer; 20, light source; 21, LED lamp plate; 22, lampshade.
The specific embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below in conjunction with embodiment and coordinate accompanying drawing to be explained in detail.
See also Fig. 1, in present embodiment, air filter comprises the filter 10 and the light source 20 that is positioned on described filter 10 center lines of circular cylindrical; Filter 10 comprises active carbon layer 11 and the filter paper layer 12 that is positioned at active carbon layer 11 outsides, is mounted with active carbon in described active carbon layer 11, and described activated carbon surface is coated with photocatalyst; Active carbon layer 11 is towards described light source 20.Because active carbon is generally grain shape, for active carbon can be distributed in active carbon layer relatively equably, active carbon layer 11 comprises framework and screen cloth, and framework is latticed and is covered the space that forms the loading active carbon by screen cloth, in use, air enters grid by activated carbon filtration from screen cloth.
Air filter of the present utility model, when the filter, part air pollutants can be by charcoal absorption or by Filter paper filtering, thereby plays the effect that purifies air at air, when light source igniting, illumination is at photocatalyst surface, and photocatalyst can produce chemical reaction, produces strong catalytic degradation function, the toxic and harmful in air of effectively degrading, kill various bacteria, and the toxin that bacterium or fungi can be discharged decomposes and harmless treatment, but deodorizing anti-soil also simultaneously.Owing to having increased photocatalyst and corresponding light source, greatly improve the air purification effect of this air filter.
Because filter 10 is annular, and light source 20 is arranged on center line, and light all can be excited photocatalyst everywhere more evenly in shining in active carbon layer 11.
In the present embodiment, light source 20 is LED light source, specifically comprise the base (not shown), annular array evenly is arranged in the Transparent lamp shade 22 that three LED lamp plates 21 on lamp socket and cover are established described three LED lamp plates 21 centered by filter 10 center lines, the light-emitting area of LED lamp plate 21 is towards described active carbon layer 11.Wherein, be strip on LED lamp plate 21, the height of the length of LED lamp plate 21 and described filter 10 is suitable, is provided with along its length plurality of LEDs lamp pearl on LED lamp plate 21.The light that sends due to the LED lamp concentrates in 120 degree, in the present embodiment, arranges by 3 LED lamp plate annular arrays, can reach light angle 360 degree irradiation, exciting light catalyst better.
In deteriorated structure, filter 10 also can the cross section be the hollow columnar as other shapes such as rectangle, squares, and the effect that adds light source due to photocatalyst equally also can improve air cleaning usefulness, but the light intensity that photocatalyst receives can be even not.
The utility model also provides a kind of air purifier, comprise housing, blower fan and air filter as indicated above, described housing is provided with air inlet and air outlet, described blower fan and air filter are fixedly installed in housing, described air inlet forms air communication channel to described filter to described air outlet, and described blower fan is arranged in this air communication channel.During the work of this air purifier, blower fan plays swabbing action to air, makes that air enters in housing from air inlet in the room in, and enters in filter and get back in the room from air outlet after active carbon layer and filter paper layer filtration successively.
