Technical field

Present invention relates in general to produce the ion generator of the galvanic electricity air flow of therefrom removing particulate matter.

Background technology

It is well known in the art using electrokinetic technique to produce air flow, by this technology electric energy is converted into flowing of air and does not need mechanical moving element.In the U.S. Patent No. 4,789,801 of authorizing Lee (1988), described such system, be described with reduced form and this patent is combined in herein as a reference as Fig. 1 at this.System 100 comprises first (" emission ") electrode group or the conductive surface 112, and it spatially is that symmetry is separated with second (" reception ") the electrode group or conductive surface 122.Just as illustrated, the emission group comprises an emission electrode, but Lee has also described the emission group 110 with a plurality of emission electrodes 112.

In this example, (for example, pulse generator) positive terminal is connected with emission electrode generator, and the negative terminal of generator is connected with receptor.(for example, 0 to perhaps+5KV), and high-voltage pulse will transmit and receive the air ionization between the electrode 112/122, produces from emission electrode 112 to collecting electrode 122 air flow 150 for pulse generator 140 output string high-voltage pulses.Particulate matter 160 is entrained in the air flow 150, also shifts to collecting electrode 122.Most of particulate matter 160 is electrostatically attracted to the surface of the collecting electrode 122 of energy collecting granules material 160, discharges system 100 so regulate air flow.Other benefit is, the high-voltage field between electrode discharge in the environment towards periphery can eliminate in the air flow with the ozone of stink.

Except particulate matter, in air, also there is VOC (VOCs) usually.VOCs is based on the chemical substance of oil, finds that its concentration raises to some extent in a lot of houses.Thousands of kinds of possible VOCs discharge from common household products.For example, VOCs can be discharged in the air by synthetic flavouring agent (as existing in soap, wax candle, air freshener, incense and the fragrance of a flower), paint, carpet, furniture, glue, plastics, pressing wood-based product (for example plywood and particieboard) even flower and other article.Formaldehyde is the VOC that a kind of meeting becomes family's specific question.Formaldehyde can exist among construction material, gap filler and binding agent, paint, furniture etc.When contact during formaldehyde, the people can experience usually that headache, extreme numbness or twinge, brains dimmedly maybe can not be focused one's attention on, anxiety, downhearted etc.In addition, formaldehyde is a kind of sensitizer, can reduce the threshold value of people to other chemical substance sensitivity.Add forced ventilation and can dilute the gas of emitting; Yet, be for example occasion of mycete of organic substance in the source of formaldehyde and/or other VOCs, the gas discharging is continuously, lastingly.The VOCs that discharges refuse as mycete is bigger to hazard ratio buoyant mycotic spore in air of health.

Except having side effects in sensitive individual, VOCs also can produce tangible stink.For example, the treatment process to many urban water resources comprises the chlorine dioxide that interpolation is used as disinfectant.When opening faucet, chlorine dioxide is along with the diffuses flow of water is gone in the air.Chlorine dioxide can combine the chemical compound that generation has disgusting abnormal smells from the patient with the VOCs that exists in the surrounding air.The concentration of VOCs and chlorine dioxide is high more, and the probability that produces stink is just high more.Till bad-smell problem will last till that VOCs concentration reduces.In the seldom airy zone of sealing, for example laundry, basement, bathroom and storeroom, such chemical compound gathers together, and causes stink stronger than draughty zone, and the time of staying is longer.

A way that solves the VOC pollution is cleaning and purifies the air that contains VOCs.In air purifier, air traction can be passed depurator with fan, and move near or by one or more carbon filters that can absorb VOCs and stink.For example, the device that uses high-efficient granule to capture (HEPA) filter passes the HEPA filter with a large amount of air of high-power fan traction usually.The HEPA filter is collected a large amount of large particulate matter (0.3 μ m and more than) and can be connected with the carbon filter that absorbs VOCs (with stink), removes VOCs from the air that passes the HEPA filter.Yet this air purifier is renderd a service limited.The HEPA filter is collected and is had any problem less than the particulate matter of 0.3 μ m, and the carbon filter that is connected with the HEPA filter finally reaches capacity and begins VOCs and foul smell are dumped in the winding border.

Therefore, wish to improve existing electrokinetic technique by making existing electrokinetic technique can from air, remove VOCs.

Fig. 2 A-2C has described a kind of air conveying-regulating system 200, and its shell comprises air inlet or the shutter 204 and the preferred preposition air outlet 206 of preferred postposition, and bottom base 208.If desired, can only provide a vent, it has air inlet passage and the air outlet passage that is communicated with vent and electrode, not only as air intake but also as air outlet slit.Preferably, shell be freestanding and/or stand vertically and/or the elongation.Carrying the inside of shell is an ion generating unit 140, preferably uses the power supply of AC:DC power supply, and this power supply can use a switch S 1 that can place 200 tops 203, unit easily to connect or excite.Ion generating unit 140 is controlled oneself, because in order to carry out operation of the present invention, except surrounding air and peripheral operation voltage, does not need to carry anything outside shell 202.

The upper surface of shell 202 comprises the grip member 244 that a user can be mentioned, and it can be used for shifting out electrode assemblie 109 from shell 202, so that cleaning electrode assemblie 109.In the embodiment shown, electrode assemblie 109 comprises 122 group 120 of 112 group 110 of first emission electrode and second collecting electrode.Mentioning parts 244 can upwards carry first group of electrode 110 and second group of electrode 120, and electrode is extracted out from the top of shell, if necessary, can also be from the unit 100 cleanings of releasing.Shown in Fig. 2 B, can with electrode assemblie 109 from the unit 100 top 203 along the longitudinal the direction of axle or elongation shell 202 vertically propose.This set can make user be easy to electrode pulled out and clean.The bottom of electrode is connected with parts 242, and electrode spatially is maintained fixed and/or is inflexible like this.In other embodiment, the bottom of electrode does not need to link to each other with parts 242.As following further discussion, the first and second electrode groups link to each other with the port of export of ion generator 140.

In another embodiment shown in Fig. 2 C, first group of electrode 110 and second group of electrode 120 can shift out from shell 202 independently of one another.In this embodiment, one first user can mention grip member 244 ' and can be used for that first group of electrode 110 shifted out 202, one second users of shell and can mention grip member 244 " can be used for second group of electrode 120 shifted out shell 202.Therefore, electrode group 110/120 can clean respectively, has proved that such meeting is favourable, for example needs the occasion of more frequent cleaning at second group of electrode, 120 to the first group electrodes 110.The first electrode group 110 can be stayed in the shell, be cleaned and the second electrode group shifted out, vice versa.And the bottom of first group of electrode 112 can be connected with one first low support component 242 ', and support component 242 can be hanged down with one second in the bottom of second group of electrode 122 " be connected.Low support component can provide rigidity, and the space length that is maintained fixed, and can prevent further that electrode group 110/120 from being destroyed in the process of frequently inserting and shifting out.In another embodiment, electrode group 110/120 does not need to be connected with low support component.

In the exemplary embodiment shown in Fig. 2 A-2C, shown first group 110 comprises single electrode 112, and shown second group 120 comprises two electrodes 122.Yet in other embodiment, first group 110 can comprise a more than electrode 112, second group can comprise more than two electrodes 122, as shown in remaining figure that will discuss below.

The common shape of the shell 202 shown in Fig. 2 A-2C is 8 fonts on the cross section, although other shape also within the spirit and scope of the present invention.Such system height from the top to bottom can be for example about 1m, and width from left to right can be about 15cm, and the vertical degree of depth can be about 10cm.Selectively, also can use various other size and dimensions.The structure of band shutter provides competent inlet air hole and exhaust vent in the shell mechanism of economy.Except its position, the difference of any essence needn't be arranged between the

air vent

204 and 206 with respect to second electrode.These air vents can guarantee that competent stream of ambient air is inhaled into or can be used in the system 200, and guarantee the competent an amount of O that contains ₃Ionized air stream from system 200, flow out.

When making system's 200 energisings with S1, the high pressure or the high potential of ion generator 140 outputs produce ion at first electrode, and these ions attracted to second electrode.Ion mobile on " IN " to " OUT " direction has Ionized air molecule, and therefore, galvanic electricity ground produces the effluent of ionized air." IN " symbolic representation among Fig. 2 A-2C has the inlet of the surrounding air of particulate matter 160.The clean air outlet of particulate matter is removed in " OUT " symbolic representation substantially, and wherein the particulate matter Electrostatic Absorption is on the surface of second electrode.In the process that produces ionized air stream, produced an amount of ozone (O valuably ₃).Can wish that inner surface for shell 202 provides the electrostatic defending cover can detected electromagnetic radiation to reduce.For example, can within shell 202, shelter-clad be installed, perhaps the part inner surface coated with metal of shell 202 be coated with lacquer and reduce such radiation.

In one embodiment, cross-sectional outer is avette or oval substantially, and the side has groove.Therefore section appears to have point image and resembles 8 words.Has difform section, for example but be not limited only to rectangle, egg type, tear drop shape or circular shell also falls within the scope of the present invention.Shell preferably has elongated structure.The shape of shell preferably has the function of hold electrodes assembly, and this point can become clearly afterwards.

As mentioned above, shell has entrance and exit.Entrance and exit is all covered by fin or shutter.Each fin all is and next fin thin ridge separately, thereby when air flow through shell, each fin produced minimum resistance.Fin is a level, and gets the direction of the upright shell of penetrating element.Therefore, this preferred embodiment in, fin is basically perpendicular to the direction of electrode.Arrange the arrangement mode of entrance and exit fin to give the outward appearance of unit a kind of " understanding thoroughly ".So user can be understood thoroughly this unit from the outlet that enters the mouth.User be can't see the parts of motion in shell, only see that a purification passes the immobilized unit of air wherein.Selectively, in another preferred implementation, fin can be parallel with electrode.In other embodiment, other locate mode of fin and electrode also is possible.

Use air conveying-regulating system from air, to remove VOCs and foul smell

Photocatalysis be one utilize the ultraviolet (UV) of catalyst and catalyst thus radiation is decomposed or the oxidation harmful chemical of the VOCs technology of removing pollutant from air flow for example.For example, a kind of such catalyst is micropore titanium oxide ceramics (titanium dioxide, TiO ₂), can be on the surface that will place air flow with this catalyst-coated of skim.Titanium dioxide is that a kind of band-gap energy is the semiconductor light-catalyst of 3.2eV.When titanium dioxide with wavelength during less than the photon irradiation of 385nm, make electronics cross band-gap energy from valence band to the conduction band transition.The electronics hole that obtains makes it can participate in chemical reaction to certain life-span is arranged.Can use UV light source (perhaps having the radiation source outside UV spectrum less than the 385nm wavelength) to activate titanium dioxide ceramic, when it is subjected to shining, can oxidation be present in the VOCs in the air flow, be water and carbon dioxide with these compound decomposition.In addition, can eliminate microorganism in the air flow basically with UV lamp radiation air flow.

In the several embodiments of described electrode assemblie, space or drive electrode can comprise photocatalysis coating herein, perhaps can embedding of photoactivation material or dipping.Use photocatalysis coating can promote very oxidation near the air of space or drive electrode group.In other embodiment, the wall of system shell can embedding of photoactivation material or dipping, and perhaps this wall can comprise photocatalysis coating.Yet in a further embodiment, can near small part be applied by catalysis material or the loose structure of embedding, for example independently screen cloth or grid are installed in the air flow of contiguous UV light source.Loose structure may not be a grating texture.For example, loose structure can be network structure, perhaps helicoidal structure.In addition, in other the embodiment, there be (for example, in boiler tube) in air flow at some, loose structure can be placed in this air flow (for example, to be arranged in the boiler tube), rather than be placed in the air flow that is produced by electrode assemblie.The UV light source should be arranged on the position that makes porous surface obtain the UV light radiation.A lot of different modes of the photocatalysis material being introduced in the air flow are arranged.

Can use various types of catalyst in the photocatalysis coating, as mentioned above, photocatalysis coating can comprise titanium dioxide ceramic.In other embodiment, photocatalysis coating can comprise a kind of selectable metal-oxide, for example zinc oxide, copper oxide, silicon oxide etc.The oxide of known manganese, copper, cobalt, chromium, ferrum and nickel has activity in oxidation reaction.And, can use mixed oxide to carry out photocatalysis.For example, in some cases, Cupric chromate(III). (CuCrO ₄) have at least an effect with the same accelerating oxidation reaction of copper oxide (CuO).The suitable example that the coating that can be used for embodiments of the present invention is arranged.Further, noble metal is effective for oxidation VOCs.For example, known on platinum and palladium oxidation reaction can take place rapidly.In some embodiments, noble metal can flood or be coated on the surface as coating, for example, use (platinum and palladic consumption depend on the concentration of the VOCs of existence, but be effective with respect to a few percent of the total surface area of its coating) with other material.Use alkali metal photocatalysis coating oxidation VOCs may produce the carbon monoxide (CO) as oxidized byproduct.In an embodiment of this aspect, a kind of noble metal, for example platinum or palladium are coated on the alkali metal photocatalysis coating with deposition, dipping or other mode, perhaps comprise on the surface or loose structure of alkali metal photocatalyst.Platinized titanium pottery for example known in the state of the art can strengthen the further oxidation of CO.The photocatalysis material that those of ordinary skill in the art can understand other type also within the spirit and scope of the present invention.

Fig. 3 A-6 represents the embodiment of the galvanic electricity air conveying-regulating system according to the present invention, and it has the elimination of improvement or the ability that comprises microorganisms such as antibacterial, pathogenic bacteria, virus in the destruction air flow, and the ability of the VOCs in the minimizing air flow that improves.Specifically, Fig. 3 A-6 represents the embodiments of various preferred horizontal or vertical shells 302, has the operation control assembly that is used for control system 300 of the top surface 303 that is positioned at shell 302.

Fig. 3 A is the perspective view that is used for according to the shell 302 of the system of an embodiment of the invention.Shell 302 can be made by lightweight, cheap material, and this material also can stand to be exposed to for a long time the UV-C level light that derives from the UV lamp (describing hereinafter) that is positioned at shell 302.Non-" hard " material is exposed to light following time of UV-C for example and may As time goes on degenerates, and therefore is not suitable for using.As just example, shell 302 can be used

ABS resin (material label VW300 (f2)) is made.This resin can be used with UV light by insurance laboratory (UL) company proof by the global product manufacturing of general electronic corporation plastics.Making shell 302 from the material of other suitable UV also drops in protection scope of the present invention.

In one embodiment, shell 302 can be a kind of of avette, oval, tear drop shape or egg type.Shell 302 comprises at least one air intake 304 and at least one air outlet slit 306.As what use herein, be appreciated that inlet 304 is " upstreams " with respect to outlet 306, outlet 306 is " downstreams " with respect to inlet 304.Shown in big hollow arrow, " upstream " and " downstream " describes that air flows into, passes, the overall flow of outflow system 300.

What cover inlet 304 and outlet 306 is fin, shutter or baffle plate 305.That fin 305 preferably extends or axial, therefore, its perpendicular positioning is reduced entering and the resistance of the air flow of discharge system 300.Preferably, fin 305 is positioned proximate to is parallel at least the second passive electrode group 120.Fin 305 also can be parallel to the first emission electrode group 110.This structure helps air to flow through system 300, and can prevent that UV light or other photocatalyst that the UV lamp sends from leaving shell 302.Only as an example, if the width on the long limit that exports from entering the mouth to is 8 inches, collecting electrode 122 (shown in Fig. 5 A) can be 1 1/4 on the mobile direction of air " wide, fin 305 can be 3/4 on the mobile direction of air " or 1/2 " wide.Certainly, other size also drops within size of the present invention and the scope.In addition, other fin and the shell shape of non-aerodynamic also drop within the spirit and scope of the present invention.

The cross section of shell 302 can be a kind of of avette, oval, tear drop shape and egg type so that enter the mouth 304 and export 306 narrower than housing.Thereby because the width of shell 302 and cross-sectional area increase, air flow is slack-off when air flow passes the A-A transversal shown in Fig. 5 A for example.So microorganism in the air flow and VOCs have the long time of staying, the UV lamp that makes microorganism be used as sterilizing unit kills, and VOCs is being reacted and oxidation in the presence of as the activatory photocatalysis material of the UV lamp of activating apparatus.

The operation control of Fig. 3 B illustrative system 300.On the end face 303 of shell 302, air velocity console panel 314 is arranged, strengthen button 316, functional disc 318, and overload/cleaning lamp 319.That air velocity console panel 314 has is low, in and the setting of Senior Three kind, user can therefrom be selected.The difference of the voltage between air velocity and electrode that is connected ion generator 140 or the electrode group is directly proportional.Low, in and the Senior Three kind be arranged on the different predefined voltage difference of generation between first and second groups.For example, " low " is provided with and can produces minimum voltage difference, and " height " is provided with and will produces maximum voltage difference.That is, " low " is provided with and will makes system 300 produce the slowest air velocity, and " height " is provided with and will makes system 300 produce the fastest air velocity.Air velocity is moved according to the method for the following stated by what illustrated electronic circuit produced among Fig. 9 A and the 9B.

Functional disc 318 makes user can select " ON ", " ON/GP " or " OFF ".Unit 300 produces from 304 air flows to outlet 306 that enter the mouth as static air conveying-actuator, and selects " ON " setting or " ON/GP " when functional disc and remove degranulation when being provided with from air flow.When functional disc 318 was arranged on " ON ", the UV lamp did not move and does not send UV light in other words.Excite UV lamp 390 when functional disc is arranged on " ON/GP ", it sends UV light, kills microorganism and irradiates light catalytic active substance in the air flow.Illuminated time catalytic active substance be activated and with air flow in VOCs reaction.When functional disc was arranged on " OFF ", system 300 did not start.

In some embodiments, system 300 can also produce a spot of ozone and reduces foul smell in the room.At foul smell is because the occasion (as mentioned above) that VOCs causes activates the UV lamp and can further reduce foul smell.If the stink in the room is dense, perhaps user is thought the interim speed of accelerating removing, and can there be the button 316 of enhancing in system 300.When pressing enhancing button 316, system 300 can increase air velocity to predefined Peak Flow Rate temporarily, and produces the ozone of recruitment.The increase of ozone amount reduces the stink in the room quickly in the time of being arranged on " HIGH " than system 300.Maximum air flow speed also will increase the particle capture speed of system 300.One preferred embodiment in, press and strengthen button and can increase air velocity and ozone generating amount in continuous 5 minutes.This time period can be longer or shorter.End in predefined time period (for example 5 minutes), the previous flow velocity of selecting by console panel 314 will be got back to by system 300.

Whether overload/cleaning lamp 319 can indicate second electrode 122 whether to need cleaning, perhaps have electric arc to produce between the first and second electrode groups.In some embodiments, overload/cleaning lamp 319 sends gold-tinted or HONGGUANG.If system's 300 continuous operation surpassed for two weeks and the second electrode group is not brought cleaning out, then lamp 319 flavescence in the time in this two week.Gold-tinted is controlled by the two all timing circuits 930 (referring to Fig. 9 B) that link to each other with power setting circuit 922 as described below.After lamp 319 flavescence, system 300 can remain in operation, and lamp 319 is an indicator just.Have two kinds of methods can reset or close lamp 319: user can shift out and change the second electrode group 120 from system 300, and/or user can turn to console panel 318 " OFF " position, then it gone back to " ON " or " ON/GP " position again.When finishing one of these two steps, timing circuit 930 is reset and is begun to calculate cycle in two new weeks.

Electric arc has taken place between reddening and representing first group 110 and second groups 120 in lamp 319, and this is detected (as described below) by a testing circuit 932 that is connected the IGBT switch 926 among Fig. 9 B and collects between the agitator 924.When electric arc produces, system 300 will close automatically.System 300 just can restart after resetting.In order to reset system 300, after system 300 closes, should shift out shell 302 with second group 120 earlier.Then clean second electrode 120 and it is put back in the shell 302 and go.Then can open system 300.If do not produce electric arc, system's 300 runnings also produce air flow.If the electric arc between the electrode is also continuing, system 300 will close once more automatically, and must be provided with again.

Fig. 3 C represents that part shifts out second electrode 122 of shell 302.In this embodiment, handle 344 is attached on the electrode mounting bracket 345.Support 345 guarantees that second electrode 122 is fixed, parallel structures.Another similar support 345 is attached on second electrode 122 that mainly is positioned at the bottom (not shown).Parallel to each other with two supports 345 that second electrode 122 is in a straight line, and with the air flow that flows through shell 302 in the same way.Preferably, support 345 is nonconducting surfaces.

Latch lever 318 stretches out from the bottom of handle 344.When second electrode 122 was put into shell 302 fully, handle 344 leaned against within the end face 303 of shell.In this position, latch lever 318 puts in chain groove 317, and excites the switch that links to each other with the circuit of unit 300.When handle 344 shifts out, latch lever 318 is pulled out the switch opens circuit from chain groove 317 from shell 302.When switch is in the position of opening, unit 300 inoperation.Like this, if when system's 300 operations second electrode 122 is shifted out from shell 302, latch lever 318 1 is deviate from from chain groove 317, and system 300 just closes.

Fig. 3 D represents to be installed in the shell 302 on estrade or the base 308.Shell 302 has inlet 304 and outlet 304, and base 308 is placed on ground.Base 308 makes shell 302 be in the upright position.Shell 302 and base 308 are connected also within the scope of the invention by axle.Shell 302 comprises oblique end face 302 and oblique bottom surface 307.These surfaces 304 304 slope inwardly to outlet from entering the mouth, and a kind of fairshaped outward appearance and effect are provided extraly.

Fig. 3 E represents to have movably the shell 302 of back plate 324, and can make user be easy to get at and shift out UV lamp 390, for example, when UV lamp 390 end-of-lifes.Not necessarily, removing back plate 324 can be near having photocatalysis material coating, contiguous UV lamp 390 and being in net or grid 392 in the air flow, so that for example need to apply again or during regeneration (for example by roasting at high temperature), can from shell 392, shift out grid 392 when grid 392.In commercial Application, the alkali metal oxide photocatalyst in known modern times can use five, six years and performance does not reduce.Among this embodiment, back plate 324 has defined air intake and has comprised vertical shutter.Back plate 324 has along the whole length of plate 324 and is positioned at chain projection 326 on every side.Chain projection 326 is " L " shape as shown.Each projection 326 all extends internally on the direction away from plate 324 to shell 302, and is then outstanding downwards, parallel with the edge of plate 324.Comprise that selectively having difform projection 326 drops within the spirit and scope of the present invention.Each projection 326 independently, movably with shell 302 in the grooves 328 that form chain.Back plate 324 also has and is arranged on the chain eccentric lever (not shown) of plate 324 bottoms and groove 230.For plate 324 is moved apart shell 302, lever 326 is pushed away shell 302, back plate 324 is vertically upwards slided break away from groove 328 up to projection 326.So just plate 324 is pulled out shell 302.

Plate 324 can comprise safety device shutdown system 300 when shifting out plate 324, and system 300 can not be turned round.The projection (not shown) that plate 324 has a rear portion to stretch out, when plate 324 was fixed on the shell 302, it and safety interlocking groove 327 meshed.Only as an example, when back plate 324 was fixed on the shell 302, rear projection was depressed the safety switch that is positioned at groove 327.Only when the rear projection in the plate 324 is inserted safety interlocking groove 327 fully, system's 300 entrys into service.When plate 324 when shell 302 shifts out, the projection that stretch out at the rear portion shifts out from groove 327, cuts off the power supply of whole system 300.For example, if user movable plate 324 when system's 300 operations, UV lamp 390 sends UV light, and the projection one that stretch out at the rear portion is deviate from from groove 327, and system 300 just closes.Preferably when after plate 324 move an only very short segment distance (for example, 1/4 ") system 300 from shell 324 and just close.The class of operation of this safety switch and latch lever seemingly.

Fig. 4 illustrates another embodiment of shell 302.In this embodiment, can UV lamp 390 be lifted from shell 302 and UV lamp 309 is removed from shell 302 by end face 303.Shell 302 not necessarily has removable back plate 324.The substitute is a handle 448 that is fixed on the UV lamp 390.When UV lamp 390 during, handle 448 is recessed in the end face 303 of shell 302 in shell 302 the insides.The handle 448 vertical shells 302 that propose can be shifted out UV lamp 390.

UV lamp 390 can be to be positioned at shell 302 with second group of electrode, 120 similar modes, so that when the UV lamp is vertically proposed the end face 303 of shell 302, to the electronic circuit disconnection connection of UV lamp power supply.The UV lamp can be installed on the fixing device with the circuit contact that can be connected with the circuit of Fig. 9 A, if UV lamp 390 and fixing device are drawn out, circuit contact is thrown off.And when handle 448 was mentioned from shell 302, a cut-out switch cut out system 400.This safety component guarantees that system 400 can not turn round, and prevents that the people from directly seeing the UV light that UV lamp 309 sends when UV lamp 390 is not placed in the shell 302 safely.UV lamp 390 injected again cause fixing device to combine once more in the shell 302 with circuit contact.In similarly still inconvenient mode, can design the UV lamp is shifted out from the bottom of shell 302.

UV lamp 390 preferably sends to have wavelength and is about the light of 245nm and the UV-C lamp of radiation (being called UV radiation and UV light in bonded document).This wavelength can reduce effectively or destroy antibacterial, pathogenic bacteria and the virus that is exposed to wherein, and activation is coated at least a portion grid 392 effectively, perhaps selectively, is coated in the photocatalysis material on the part inner surface of part space electrode or shell.For example, UV lamp 390 can be the TUV 15W/G15 T8 of Phillips type, and the about 25mm of the diameter of a kind of 15W is about the tubular lamp bulb of 43cm.Another kind of suitable UV lamp is Phillips TUV8W/G8 T6, and the about 15mm of the diameter of a kind of 8W is about the bulb of 29cm.Also can replace and use other lamp that can send the wavelength that needs.

As previously mentioned, shell 302 prevents that the people from seeing the UV light of UV lamp 390 generations that are arranged within the shell 302.Fig. 5 A and 5B illustrate the optimum position of UV lamp 390 within shell 302, and shown between UV lamp 390 and the electrode assemblie 109, UV lamp 390 and enter the mouth 304, the spatial relationship between outlet 306 and the entrance and exit shutter.

In one embodiment, inner surface 501 diffusions of shell 302 or absorb the UV light that UV lamp 390 sends.UV lamp 390 can send the UV light on some inner surfacies that can shine directly into shell 302 501.As just example, the inner surface 501 of shell 302 can be by rough coating, and perhaps the coating of no-reflection or pigment form, and so just absorbs or reflection UV light, prevents that UV light is from entering the mouth 304 or export 306 leakages.

As discussed above, the fin 305 that covers inlet 304 and outlet 306 also limits user and sees sight line in shell 302.Fin 305 is vertical orientated in inlet 304 and outlet 306.The depth D of each fin 305 is preferably firmly got is enough to stop the people directly to see to inner surface 501.In one embodiment, import and export 306 or enter the mouth 304 the time, pass through to move and directly to see inner surface 501 when seeing.In shell 302, make the people " see through " system 500 from seeing between the fin 305.That is to say that user can be seen into from air inlet 304 or air outlet 306, finds out from another mouthful.Should be understood that,, can it seems light or radiance from shell 302 inside so if light has the wavelength of the non-UV that can watch.In general, when UV light 580 shone the inner surface 501 of shells 302, UV light 580 moved from UV spectrum.Light wavelength becomes suitable visible spectrum from UV spectrum.Therefore, any light that sends from shell 302 can be watched.

Designed enclosures 302 is so that the minimizing optimization of microorganism in the air flow and VOCs.UV light depends on the length that this quasi-microorganism is subjected to UV light 580 irradiation times to action of microorganisms.Therefore, UV lamp 390 can be arranged on the flow inside of the slowest shell 302 of air.Similarly, catalytic specie depends on the length that gives the time that these VOCs react in the presence of catalytic specie to the effect of VOCs.Shown in Fig. 5 A-6, in preferred embodiment, UV lamp 390 is installed in the inside of shell 302 along line A-A.Shell 302 forms the fixed space that air therefrom passes.Air admission has the inlet 302 of width smaller and cross-sectional area along the part of line A-A with respect to shell 302.Because shell 302 is along the width of A-A line and cross-sectional area width and the cross-sectional area greater than inlet 302, from entering the mouth 304 to line A-A, air flow will slow down.By UV lamp 390 is placed along the A-A line basically, when the UV light 580 that sends by UV lamp 390, air has the longest time of staying.Similarly, grid 392 almost is placed on (perhaps forming a little angle with this plane) in the plane that A-A along the line forms the overwhelming majority of grid 392 surface areas is exposed in the UV light 580 that air flow and UV lamp 390 send, be coated in the performance that the VOCs that causes on the grid 392 in the air flow decomposes the catalytic specie of (or oxidation) thereby strengthen.Yet, the UV lamp is placed in the shell 302 Anywhere, preferred (but not getting rid of other situation) in the upstream of electrode assemblie 109 also within the scope of the invention.Similarly, grid 392 also can be placed on any position that can make the photoactivation that catalytic specie launched by the UV lamp in the shell 302.In another embodiment, can apply the photocatalysis material on shell wall itself, perhaps the photocatalysis material can be loaded or be impregnated into the inner surface of shell 302.

Housing or shell 570 are basically around UV lamp 390.Housing 570 stops UV light 580 directly to shine to inlet 304 or exports 304.One preferred embodiment in, in the face of the inner surface of the housing 570 of UV lamp 390 is non-reflecting surfaces.Only as an example, the inner surface of housing 570 can be a rough surface, is perhaps painted dark, lacklustre color, for example the black of Wu Ze.In some embodiments, can also apply the photocatalysis material at the inner surface of housing 570 and replace the coated inner surface of grid 392 or shell 302, perhaps except the coated inner surface of grid 392 or shell 302, the inner surface at housing 570 applies the photocatalysis material in addition.Shown in Fig. 5 A and 5B, UV lamp 390 is the round lamp tubes that are parallel to shell 302, one preferred embodiment in, UV lamp 390 equates with the finned length that covers inlet 304 and outlet 304 basically or is shorter.UV lamp 390 is outwards launched UV light 580 with 360 °.The UV light 580 of direct directive inlet 304 of housing 570 stop portions and outlet 304.Shown in Fig. 5 A and 5B, there is not to make the people to see the direct sight line of passing through inlet 304 and outlet 304 of UV lamp 390.Selectively, housing 570 can have inner reflection surface so that UV light 580 is reflected in the air flow.

In the embodiment shown in Fig. 5 A, UV lamp 390 is provided with along the limit of shell 302, and near inlet 304.Air is subjected to the irradiation of the UV light 580 that UV lamp 390 launches immediately by after the inlet 304." U " shell body 570 of elongation has sealed UV lamp 390 basically.Housing 570 has two frames to support and UV lamp 390 is connected with power supply.Grid 392 is arranged near the UV lamp 390, for example, is the monolithic that is provided with along the plane with the A-A line parallel.In another embodiment, grid 392 can be arranged on along the plane with A-A line oblique near the UV lamp 390, for example, becomes the plane of miter angle along the plane with the A-A line parallel.Be arranged in such a way grid 392 and can make bigger surface area not only directly be subjected to the irradiation of UV lamp 390, and be exposed in the air flow.In some other embodiments, with grid 392 along being provided with A-A line plane orthogonal.The arrangement of grid 392 in shell 302 can change and depend on the material that for example is used for applying grid 392, UV light 580 that UV lamp 390 sends amount, UV lamp 390 the position and arrange, air velocity, the size of grid 392, and/or the size of shell 302 etc.One of ordinary skill in the art will appreciate that the different arrangement mode of grid kind more than 392.

In an embodiment shown in Fig. 5 B, housing 570 comprises two surfaces that separate.First wall 574a is at UV lamp 390 and enter the mouth between 304, and preferably " U " shape has a concave surface facing to UV lamp 390.The concave surface of first wall 574a preferably is non-reflecting surface.Alternatively, the concave surface of first wall 574a can be with UV light 580 to external reflectance to the air-flow that passes through.First wall 574a with other shape also within the scope of the invention, such as but not limited to plate shaped, " V " shape and " C " shape.In one embodiment, first wall 574a can with removable back plate 324 global formations, when from shell 302, shifting out afterwards plate 324, also moved first wall 574a like this, expose UV lamp 390.For example be easy to get at UV lamp 390 to move or to install UV lamp 390.

The second wall 574b is " V " shape, between UV lamp 390 and electrode integrated 109, stops user to look around and see the UV light 580 that UV lamp 390 sends by exporting 304.The second wall 574b can have the concave surface of non-reflection.Selectively, the second wall 574b can have reflective concave surface outwards UV light 580 to be reflected to the air flow that is passing through.Have other shape, for example the second wall 574b of (but being not limited to) plate, " U " shape or " C " shape also within the scope of the invention.In such embodiment, grid 392 is made up of two parts that are positioned at relative both sides, and contiguous UV lamp 390, UV light 580 exposure cages 392 that send of UV lamp 390 activate and are coated in the catalytic specie on the grid 392 so that cause the substance decomposition of VOCs in the air flow like this.

Housing 570 not necessarily comprises fin 572.Fin is separated, preferably is substantially perpendicular to air flowing stream.In general, fin 572 can also stop UV light 580 directly to shine to inlet 304 and outlet 306.Fin 572 can have surface black or non-reflection.Alternatively, fin 572 has reflecting surface.Reflecting surface can stop the surface of housing 570 and fin 572 to absorb UV light 580, air-flow and grid 392 that more UV light 580 pilot flow are crossed.Housing 570 can also comprise reflecting surface with the UV photoconduction to fin 572, make the air-flow that flows through and grid 392 obtain maximum irradiation.The UV light 580 that housing 570 and fin 572 send UV lamp 390 is crossed the air-flow that crosses of shell 302 with vertical substantially direction pilot flow.This prevents UV light 580 direct directive inlets 304 or exports 306.

In addition, inwall 501 can apply the glazing catalytic specie, thereby when air contacted with inner surface 501, VOCs was by the photocatalysis material oxidation through irradiation.In other embodiment, aforesaid grid with photocatalysis material coating can be arranged on the position near UV lamp 390, for example, and between inner surface 501 and UV lamp 390.In a further embodiment, the plate that shape probably meets with inner surface 501 and the photoactivation material applies or other surface interconnect movably with inner surface or are positioned near the such air in the position of inner surface 501 and plate or other surperficial contact and airborne VOCs and catalytic specie reaction.

Fig. 5 A-6 illustrates the embodiment of electrode assemblie 109.Electrode assemblie 109 comprises the first emission electrode group 110 and the second collecting electrode group 120, preferably is arranged on the downstream of UV lamp 390.Electrode assemblie 109 produces ion just, causes air streaming current mistake between the first emission electrode group 110 and the second collecting electrode group 120.The electrode 112 that comprises two wire-shaped for first group 110, and second group 120 comprise three " U " shape electrodes 122.Each " U " shape electrode comprises a front end and two trailing edges.First group 110 and second groups 120 that comprise electrode with other shape also fall within the scope of the present invention.For example, can be tear drop shape, " Z " shape, " V " shape etc. from second group 120 electrode 122.And, from first group 110 electrode 112,, can also be tear drop shape and can comprise a for example SI semi-insulation surface except being the wire-shaped.In addition, if each emission electrode 112 is equally spaced to 122 with corresponding contiguous collecting electrode, then can use the electrode of any number.In addition, electrode assemblie 109 can comprise the space electrode, towing electrode and/or focusing electrode etc.Be understandable that, in the system shown in Fig. 2 A-6, can use countless different electrode assemblie structures.

Fig. 7 illustrates the electrode assemblie 109 of the galvanic electricity regulating system 100 that is used for the selectable embodiment according to the present invention.System comprises the first emission electrode group 120 of an emission electrode 112, second collecting electrode group 120 of collecting electrode 122 and the drive electrode 732 through applying the 3rd group 730.In this embodiment, first group of 110 anode with high voltage power supply 340 is electrically connected, and second group of 120 negative terminal with high voltage power supply 140 is electrically connected.The 3rd group of 730 ground connection of the drive electrode 732 through applying, each drive electrode 732 comprises a conductive electrode 734 that applies catalysis material 736.

In system's operating process, high voltage power supply 140 makes emission electrode 112 positively chargeds, and collecting electrode 122 is electronegative.For example, the voltage on the emission electrode 112 can be+6KV, and the voltage on the collecting electrode 122 can be-10KV, forms the electric potential difference of 16KV between emission electrode 112 and collecting electrode 122.This electric potential difference produces the high-strength electric field of high concentration around emission electrode 112.More particularly, 122 corona discharge takes place from emission electrode 112 to collecting electrode, produces positively charged ion.Near the emission electrode 112 granule (for example, dust granule) is by positive charge on the ion band.Positively charged ion is subjected to the repulsion of positively charged emission electrode 112, is attracted to electronegative collecting electrode 122 and deposition thereon.
