In order to realize foregoing invention object, the present invention discloses a kind of air circular purification device and comprises: a blower fan, and for compulsory circulation air, described blower fan is connected with an air channel; One photocatalyst filtering net, described photocatalyst filtering net covers described air channel completely; One LED excitation source, described LED excitation source is for irradiating described photocatalyst filtering net; The wave-length coverage of described LED excitation source is 320-400nm.
Further, the base material of described photocatalyst filtering net is made up of metallic nickel, and described photocatalyst filtering net surface also comprises titanium dioxide nano coating.
Further, described LED excitation source also comprises a fin.
Further, the dividing plate that air outlet place equidistant setting at least two group in described air channel is parallel.
Further, the air inlet in described air channel is the air outlet of described blower fan.The vibration that the peripheral portion of described blower fan produces when filling Double-side foam celloidin to fix described blower fan and to cushion the work of described blower fan.
The present invention discloses a kind of air circulation purifying method simultaneously, it is characterized in that, comprise: compulsory circulation one air to be clean, make described air to be clean flow through a photocatalyst filtering net irradiated by LED excitation source, the wave-length coverage of described LED excitation source is 320-400nm.
Compared with prior art, the photocatalyst ground that the technical program adopts and nano surface coating all belong to inorganic material, all can not produce in use procedure and after losing efficacy material human body and environment being had to harm; And excitation source application is also current state-of-the-art LED technology, this light source has the advantages such as long service life, environmental protection, low energy consumption, and the ultraviolet produced belongs to UV-A level (320-400nm), belongs to human-body safety wave band.Can be used in refrigerator, refrigerator, tableware storage cabinet etc. to fresh-keeping, sterilize, eliminate the unusual smell in the utensil of requirement, also can use as the air purifier of family separately.
Accompanying drawing explanation
Can be further understood by following detailed Description Of The Invention and institute's accompanying drawings about the advantages and spirit of the present invention.
Fig. 1 is the structural representation of air circular purification device disclosed in this invention;
Fig. 2 is the air channel circulation figure of air circular purification device disclosed in this invention;
Fig. 3 is the circuit diagram of air circular purification device disclosed in this invention.
Detailed description of the invention
Fig. 1 is the structural representation of air circular purification device involved in the present invention.As shown in Figure 1, this air circular purification device is made up of upper cover 1 and base 8.When this air circular purification device is run in a storage space, the contaminated air with antibacterial, abnormal flavour is sucked by air intake vent 12, is discharged from air outlet 11 by the air after purification.
This air circular purification device specifically comprises upper cover 1, working indicating plate 2, control circuit board 3, LED fin 4, LED5, inorganic filter net (or claiming photocatalyst filtering net) 6, blower fan 7, base 8.When circuit provides power supply, control circuit 3 starts blower fan 7, by storage space with antibacterial, abnormal flavour contaminated air by the air intake vent 12 of upper cover 1 be drawn into purification air channel.Simultaneously, control circuit 3 LED5 started in purification air channel sends ultraviolet light source and sterilizes, utilize LED light source to trigger the inorganic overanxious net 6 purified in air channel simultaneously, it is made to produce the extremely strong free hydroxy of oxidability and active oxygen, destroy the cell membrane of antibacterial and the protein of solidification virus, kill bacteria Sum decomposition organic pollution, reaches the object of sterilization, deodorization, mildew-resistant, anti-fouling and self-cleaning, and the air after purification enters in storage space by the air outlet 11 finally by upper cover 1.The air of storage space by with the purification of upper air duct loop cycle, can reach best sterilization, deodorizing effect, and plays fresh-keeping effect to the article of storage.
Photocatalyst is under the irradiation of light, similar photosynthetic light-catalyzed reaction can be produced, produce the extremely strong free hydroxy of oxidability and active oxygen, there is very strong photoredox function, the various organic compound of oxidable decomposition and part inorganic matter, the cell membrane of antibacterial and the protein of solidification virus can be destroyed, can kill bacteria Sum decomposition organic pollution, organic pollution is resolved into free of contamination water (H
2o), carbon dioxide (CO
2) and other innocuous substance, thus there is extremely strong sterilization, deodorization, mildew-resistant, anti-fouling and self-cleaning, air purification function.
The base material of photocatalyst filtering net 6 used in the present invention is made up of metallic nickel, and the surface of this photocatalyst filtering net 6 comprises a nano coating, and this nano coating can be titanium dioxide.
The neighbouring placement one UV-LED lamp 5 of photocatalyst filtering net 6, for generation of the ultraviolet between 320-400nm wave band.This ultraviolet triggers photocatalyst filtering net 6 and generates free hydroxy and active oxygen.The pollutant flowed through in the air of this photocatalyst filtering net 6 can be become tasteless nontoxic material by free hydroxy with active oxygen Direct Resolution, simultaneously free hydroxy and active oxygen decomposing bacteria cell wall, to reach the effect of sterilization.
Use a blower fan 7 that air is carried out circulation by force in the present invention, as shown in Figure 2.This air circular purification device completely cuts off for entering air channel and exhaust passage by this blower fan 7 and a dividing plate 14 completely.Utilize the running of blower fan 7, air to be clean by air intake vent 12 enter into air channel laggard enter blower fan 7, then to be flowed out from air outlet 11 after photocatalyst filtering net 6 filters by the air outlet of blower fan 7.With the fan used in prior art by comparison, the design of this structure can realize treating purify air one inhale one and go out, make the complete circulating filtration of air, there will not be the problem at sterilization dead angle.
The air intake vent of blower fan 7 is positioned at the air outlet of blower fan 7, the air outlet distribution at least two group deflectors 13 in the air channel of this blower fan 7.This deflector 13 equidistantly distributes in air outlet place, is parallel to each other, and evenly mildly flows out from air outlet for enabling the fresh air after deodorization and sterilization.
The surrounding filling part Double-side foam celloidin of blower fan 7, for fixing blower fan 7, buffering blower fan 7 vibrates.This sterilizing, deodorizing and fresh keeping device also arranges a blue light display lamp (not shown).When this sterilizing, deodorizing and fresh keeping device runs, display lamp Chang Liang.
Compared with prior art, the photocatalyst ground that the technical program adopts and nano surface coating all belong to inorganic material, all can not produce in use procedure and after losing efficacy material human body and environment being had to harm; And excitation source application is also current state-of-the-art LED technology, this light source has the advantages such as long service life, environmental protection, low energy consumption, and the ultraviolet produced belongs to UV-A level (320-400nm), belongs to human-body safety wave band.Can be used in refrigerator, refrigerator, tableware storage cabinet etc. to fresh-keeping, sterilize, eliminate the unusual smell in the utensil of requirement, also can use as the air purifier of family separately.
Just preferred embodiment of the present invention described in this description, above embodiment is only in order to illustrate technical scheme of the present invention but not limitation of the present invention.All those skilled in the art, all should be within the scope of the present invention under this invention's idea by the available technical scheme of logical analysis, reasoning, or a limited experiment.
