Description
Technical field
The utility model relates to a kind of air purifier, and more particularly, relate to a kind of such air purifier: it so compact it can be arranged in the glass stand of vehicle, can deodorizing effectively, collect dust and sterilization, and allow to change filter in a simple manner decoupled.
Background technology
Titanium dioxide (TiO
2) in its substrate covered, there is high tack, and when light activated light (mainly ultraviolet light) can be caused to be applied on it, show photocatalytic activity.
Especially, therefore the light-catalyzed reaction of titanium dioxide for such as antibacterial effective with deodorizing aspect, and is frequently used in purification of air.Such as, a kind of method purified air, wherein, when air is by photocatalytic filter, adopts UV light irradiation TiO
2photocatalytic filter (the TiO covered
2ceramic foam filter) cause light-catalyzed reaction, this is a kind of air purification method be widely used in recent years.
Titanium dioxide is not used alone, but usually uses to cover suprabasil state.Therefore, the shape covering the photochemical catalyst of titanium dioxide is determined according to the shape of substrate usually.
The deodorizing of titanium dioxide is adopted to be mainly used in medium-sized and large-scale air-conditioning, but hardly in small-sized Household Air Purifier.
When strong UV light is occurred and provides large photocatalytic filter, large-size air conditioning has high speed air flow and area and its performance deodorizing effect difficulty especially.
But when small size air cleaner, the size of photocatalytic filter and UV generator is limited, and speed air flow also reduces.Therefore, in the urgent need to developing such air purifier, it even also demonstrates certain level or higher deodoriging properties under small light catalytic filter and UV generator.Especially, in Household Air Purifier, noise and energy consumption all will be thought over.But in the prior art, the development of air purifier concentrates on medium-sized and large-size air conditioning, and because this reason, the technology being applicable to new environment (such as family) remains inadequate.
If in order to strengthen effect with the photocatalytic filter of strong UV light irradiation small size air cleaner, then the effect of photocatalytic filter can not be guaranteed, and can rapid degradation or energy consumption will excessively be increased by the material in the region of strong UV light irradiation.In addition, the UV light emitting diode of quantity that increases is installed and the short life of UV light emitting diode will cause the increase of expense.
Further, although also can expect to use, there is the UV light emitting diode that peak wavelength is approximately 270nm, known most UV light can by Titanium dioxide absorption, the efficiency of air purifier can be increased, but the not talkative deodorizing effect having use that peak wavelength is approximately the UV light emitting diode of 270nm and show, because the UV light that the peak wavelength launched from UV light emitting diode is approximately 270nm is significantly than using peak wavelength to be that the power of the UV light of other values is faint.
In addition, carrying out new research in the shape of photocatalytic filter or size, it even can both demonstrate the effect of enhancing under little size, and relevant with the photocatalytic filter with UV light source.The shape of photocatalytic filter or size demonstrate has close ties with air drag, and the specifications and characteristics of the fan that may be used for small size air cleaner must be defined.For this reason, for the normal function of small-sized air purifier, air flowing held stationary is made to be important by the air drag reduced in air purifier.
In addition, need development to prepare the method for photocatalytic filter, it can strengthen the activation effect of photocatalytic filter self.Need not speak more, a kind of technology that even can obtain high deodorizing effect by the photocatalytic filter of low capacity is one of technology needed most in the technical field relevant to small size air cleaner.
In addition, when using UV light emitting diode and photocatalytic filter to prepare compact air purifier, fan and putting in order of different filters also will be thought over.According in the medium-sized of prior art and large-size air conditioning, first dust is collected by dust collecting filter, and then implements deodorizing by photocatalytic filter.Here, filter is the biggest factor reducing air flow pressure, and is therefore not difficult to find out, when photocatalytic filter is used to small size air cleaner, it is used to function same in medium-sized or large-size air conditioning by demonstrating with it.
In addition, need to catch the malignant bacteria entrained by the air in family.Always for filtering the filter that the HEPA filter of even bacteria removal is the flowing of remarkable slow down air, and because this reason, it is difficult to use in small size air cleaner.If what the installation of HEPA caused air to flow significantly slows down, otherwise then it can affect the deodorization functions of photocatalytic filter.For this reason, need to find another kind of device, when significantly not intervening the air flowing in air purifier, it can bacteria removal effectively.
Especially, the inner space of vehicle that the smell of smoke from cigarette is difficult to be eliminated wherein is badly in need of having the air purifier of high odor removal efficient.Because inner space of vehicle is very narrow and small, so it needs the air purifier occupying very little space or do not take up space, there is the ability purified air significantly simultaneously.Especially, because the frequent vibration of automobile, so air purifier should design like this, even if make at automotive interior, it can remain on fixing position, and can install in a straightforward manner.Especially, the air purifier for automobile is provided as accessory by most motor corporation, and the problem therefore brought is the air purifier used on a kind of automobile can not be used for other automobiles.Therefore, in the technical field relevant to automobile air purifier, to portable air purifier, there is high demand.
In addition, if air purifier is difficult to maintenance and repair or is difficult to make, then because consider its function, its marketability is lowered, and its user will feel not convenient.Therefore, need the air purifier with simple structure, and it should be easy to manufacture and be convenient to maintenance and repair.

Relation between the shell structure of air purifier and filter replacement structure
In the utility model, when being connected when procapsid 21 and being connected when upper shell 10, procapsid 21 can be connected successively securely with upper shell 10, and does not need to use screw thread, is connected unlike other housings.According to the utility model, upper shell 10 can separation as shown in Figure 5, does not need to use separating tool.After upper shell 10 is separated, procapsid 21 also can not use separating tool ground separated.
Hereinafter, the syndeton of procapsid 21 and upper shell 10 will be explained.
Fig. 6 is the perspective view of upper shell 10 of the present utility model.Upper shell 10 comprises cylindric side part 11, and from the stepped portion 12 that the bottom of cylindric side part 11 extends internally.The internal diameter limited by stepped portion 12 equals or slightly larger than the diameter of lower house 20, such upper shell 10 can assemble around the outside of lower house 20, and move to the top of inner shell 30 from the bottom of lower house 20, with such state, wherein lower house 20 is attached to inner shell 30.
Lower house 20 comprises: cylindric side part 211,221, has the internal diameter less than upper shell 10; Stepped portion 213,223, is formed at the top of cylindric side part 211,221 respectively; With ladder side part 214,224, upwards extend from the end of stepped portion 213,223 respectively.The diameter of ladder side part 214,224 is equal to or slightly less than the internal diameter of cylindric side part 11.The stepped portion 213,223 of lower house 20 is connected with the stepped portion 12 of upper shell 10, when upper shell 10 moves up along the outer surface of lower house 20, limits moving upward of upper shell 10 whereby.At the confined At The Height that moves upward of upper shell 10 as above, the upper end of upper shell 10 is connected with top shell 40.
As shown in Figure 6, in the inner side of upper shell 10, define locking projections 14 and positioning convex 15.Before procapsid 21 in stepped portion 213 and front ladder side part 214, define depression 216 in the position corresponding with locking projections 14, and in the rear stepped portion 223 of back casing 22, define locating slot 226 in the position corresponding with positioning convex 15.
Therefore, when upper shell 10 assembles around the outside of lower house 20 and moves, if only locking projections 14 and positioning convex 15 respectively alignment recess 216 and locating slot 226 time, upper shell 10 can be moved upwards up to latched position completely.
Meanwhile, as shown in Figure 8, in the side of inner shell 30, protruding holding tank 316 and protruding holddown groove 317 are formed adjacent to each other.Protruding holding tank 316 and protruding holddown groove 317 all have the shape corresponding with locking projections 14.But protruding holding tank 316 has the open shape in bottom, and protruding holddown groove 317 has the shape of bottom lock.Click feel projection is defined between protruding holding tank 316 and protruding holddown groove 317.
As above, when locking projections 14 and positioning convex 15 distinguish alignment recess 216 and locating slot 226, and when upper shell 10 is moved upwards up to latched position completely, after the opening shape of the bottom by protruding holding tank 316, the locking projections 14 be formed in upper shell 10 is accommodated in protruding holding tank 316.Under this state, when upper shell 10 rotates, the click feel that the inclined plane (see Fig. 6) of such locking projections 14 gets between protruding holding tank 316 and protruding locating slot 317 is protruding, and locking projections 14 is fixed to protruding holddown groove 317, fully secures upper shell 10 whereby.
Under this state, upper shell 10 move up through top shell 40 and stepped portion 213,223 is limited, and the rotation of upper shell 10 is limited by the left and right side of protruding holddown groove 316 and wall.In addition, the bottom lock shape restriction moving downward the protruding holddown groove 317 of the locking projections 14 that has been fixed of upper shell 10.
When upper shell 10 being fixed as previously discussed, procapsid 21 is also limited by upper shell 10 and back casing 22.Especially, because upper shell 10 is fixed to cover lower house 20, so procapsid 21 can also be securely held, do not need to use independent screw thread.But because upper shell 10 only covers the top of lower house 20, procapsid 21 can keep fixedly securing state fully, if the bottom of procapsid 21 has such structure, the bottom of itself and back casing 22 is with combinations such as snap-fastener modes.
Meanwhile, in upper shell 10, define passing hole 13 in the position that the opening portion 215 with procapsid 21 is corresponding.Passing hole 13 has such size, external cable is made to pass it, and opening portion 215 has such size, external cable is made to pass it, the locking projections 14 of upper shell 10 can rotate between protruding holding tank 316 and protruding holddown groove 317 simultaneously, namely, the size of opening portion 215 can be longer than the size of passing hole 13.
As Fig. 5, opening 215 is arranged on the side of right shell body 32 with such state, and wherein lower house 20 is connected to inner shell 30.Its function is the path of the motion in order to ensure external cable, and external cable can be connected to the electric energy input connector 512 of control PCB 51 by external cable through hole 322, and then can pass passing hole 13 and opening portion 215, extend to outside through the space right shell body 32 and upper shell 10.
Electric energy input connector 512 can be made up of socket, and the terminal (not shown) of external cable can insert in socket.The reason of use terminal socket is the replacing of conveniently external cable.Such as, when air purifier of the present utility model is used to automobile, 12V direct-flow cigar lighter socket can be used, but when air purifier is used in family or office, 110V or 220V alternating current can be used.Therefore, the possibility changing external cable is very high, and for this reason, external cable preferably uses terminal socket to be connected to control PCB 51.
It should be noted that, the direction that direction and the external cable of terminal insertion are drawn out is vertical.In other words, the terminal of external cable inserts (horizontal direction) with diametric(al), and the direction that external cable is drawn out is in downward direction.For this reason, if the terminal of external cable is
shape, support terminals on the direction that the inside of upper shell 10 can connect at terminal, and therefore even external cable is pulled by from outside, also can prevent external cable from deviating from.
The reason that upper shell 10 and procapsid 21 are designed to described syndeton is to not need to use separating tool to change the dust collecting filter 90 of air purifier 90 by means of only being separated upper shell 10.Especially, with the order that above-mentioned locking means is contrary, upper shell 10 is reversed rotation, and such locking projections 14 is deviate from from protruding holddown groove 317, protruding and get back to protruding holding tank 316 by click feel.Under this state, upper shell 10 is extracted downwards, as shown in Figure 5.Under this state, as shown in drawings, the part that dust collecting filter 90 inserts is exposed.Therefore, if only upper shell 10 is separated, dust collecting filter 90 can be readily replaced.
If the handle of dust collecting filter 90 is pulled, dust collecting filter 90 can be drawn out, and as shown in Figure 10, and under this state, the filter component 93 only in framework 91 can be replaced.
In addition, after upper shell 10 is separated as above, procapsid 21 can be dismantled by from back casing 22, does not need to use separating tool.Therefore, as shown in figure 11, change photocatalytic filter 80 and carbon filter 70 is possible from the part of inner shell 30, this part is exposed by dismounting procapsid 21.
Fig. 7-10 be the separated and carbon filter of all external shell (upper shell, lower house and top shell) separated after the perspective view of inner shell 30 observed from several direction, and Figure 11 is air purifier of the present utility model is in perspective view under the separated state of only upper shell 10 and procapsid 21.
About the inner shell 30 of air purifier of the present utility model, the front side of inner shell 30 has such Facad structure, and it allows all dust collecting filter 90, photocatalytic filter 80 and carbon filter 70 to be inserted into and to pull out.Therefore, after upper shell 10 is separated, dust collecting filter 90 can pull the handle of dust collecting filter 90 to change by the front of the exposure at inner shell 30.After procapsid 21 is separated, the photocatalytic filter 80 being positioned at the front of the exposure of inner shell 30 can be drawn out.
As shown in FIG. 14 and 15, the catalyst member 81 in photocatalytic filter 80 has high hardness and fragility, because it is by sintering TiO in grill-shaped ceramic bases
2obtain.Therefore, elastic buffer 82 is provided to surround catalyst member 81, is not impacted, and allow catalyst member 81 and inner shell 30 compact siro spinning technology each other with guard catalyst part 81.
TiO
2the problem of the photocatalytic filter 80 covered is that photocatalysis efficiency reduces in time, because foreign substance attachment in its surface.Although there is this problem, filter can not frequently be changed, and is because it expensive.Therefore, relevant to the regeneration of filter technology is developed constantly.Therefore, optical catalyst filter 80 need can install/dismountable structure for change or regeneration.But, because photocatalytic filter 80 has such structure, wherein elastic buffer 82 as above covers around catalyst member 81, forms one installs or removes photocatalytic filter 80 handle from inner shell 30, just as dust collecting filter 90, this is thorny.For this reason, in the utility model, as illustrated in figures 7-11, inner shell 30 only has procapsid 21 to be nonopen, but the front extended from front side and a part for side, when photocatalytic filter 80 is inserted into inner shell 30, all by opening, a part for the front surface of photocatalytic filter 80 and side can be exposed.Due to the shape of inner shell 30, hand grip can be used in the both sides of photocatalytic filter 80, and therefore photocatalytic filter 80 is easily pulled out.
Electric connection structure in air purifier
With reference to figure 8, on the surface of the left shell 31 according to air purifier of the present utility model, in succession define inside cable passing hole 312, inside cable groove 313 and inside cable guiding groove 314.In addition, inside cable through hole 315 is formed at the upper end in the front of the fan containing section 301 of inner shell 30.
Therefore, in order to the inside cable of powering to fan 60 and UV light emitting diode substrate 55 from control PCB 51 passes in succession through inside cable passing hole 312, inside cable groove 313 and inside cable guiding groove 314 from the control PCB 51 be fixed on PCB standing part 33 along the outside of inner shell 30, and through inside cable through hole 315, enter the inner space of inner shell 30 thus.The inside cable entering inner space is connected to the fan 60 of the bottom being arranged on inner shell 30, and extends to be connected to UV light emitting diode substrate 55 further.In air purifier of the present utility model, inside cable enters the inner space of inner shell 30 by the inside cable through hole 315 of fan containing section 301, it is the path between space outerpace and inner space, and therefore inner shell 30 keeps airtight conditions, further increase efficiency that air stream accelerated by fan 60 thus (if other parts of inner shell 30 are perforated, and inside cable is inserted into this part, then the partial air of flowing in inner shell 30 can be flowed out by the space between perforation and inside cable).
When seeing, seem that inside cable can be easy to enter inner shell 30 by the discharge portion 34 of inner shell 30, discharge portion 34 is arranged to contiguous control PCB 51.But, because the air flowing access in inner shell 30 is blocked by dust collecting filter 90 and photocatalytic filter 80, impossible (if cable is arranged by this route by the route of discharge portion 34, the air of inner shell 30 will around cable bypass, and therefore the air cleaning efficiency of clarifier must reduce).In addition, as above, the filter in the front of inner shell 30 can be replaced.Therefore, in the utility model, inside cable connects according to the side of above-mentioned route by inner shell 30.
As shown in Figure 10, inside cable passing hole 312 and external cable through hole 322 are arranged on the both sides on the direction of departing from filter pull-out direction.Therefore, as shown by the broken line in fig. 9, inside cable and external cable are connected to left side and the right side route of inner shell 30.This structure significantly increases the utilization rate of the inner space according to air purifier of the present utility model, inner space is very little, and the structure connecting and dismantle filter should be had in its front, and therefore air purifier of the present utility model can be made more compact.
Flow passage in air purifier
Figure 12 is showing the perspective view according to air purifier of the present utility model, it is in such state, top shell 40, upper shell 10, back casing 22 and left shell 31 are all removed, Figure 13 is the perspective view according to air purifier of the present utility model, it is in such state, and wherein top shell 40, upper shell 10, back casing 22 and right shell body 32 are removed.
According to the flow passage of air purifier of the present utility model as described below.The air that the negative pressure produced by fan 60 is sucked by the air-inlet grille 212 of procapsid 21 is through the space lower house 20 and inner shell 30, and be inhaled into the suction part 61 of fan 60, by carbon filter 70 and the air intlet 302 of the both sides of the bottom of inner shell 30.Then, air is upwards discharged from discharge portion 63 by fan 60, and it is distributed equably by movement-oriented device 37 and streamlined diverging duct 381 enters pipeline configuration, and moves up.
When air moves up, movement-oriented device 37 turns forward with streamline-shaped, and when its upwards time UV light emitting diode substrate 55 be slightly inclined upwardly, the irradiation direction of UV light emitting diode on the substrate 55 does not significantly depart from the scope of photocatalytic filter 80.As seen in Figure 13 and 2, the air flow duct that substrate 55 is set to be formed with inner shell 30 is spaced apart, and the flowing of such air can naturally be led, and reduces the kinetic energy rejection of air stream whereby.
With reference to Figure 12 and 13, streamlined diverging duct 381 has such structure, when its forward time its diameter become large gradually.Had flow passage by the air entering lower house 20 from exterior guiding by air-inlet grille 212 conversely speaking, when the air intlet 302 that it provides towards the bottom of inner shell 30 advances, flow passage becomes large by streamlined diverging duct 381.In other words, streamlined function of dispersing pipeline 381 is the areas of section of the air flowing access increased in inner shell 30, also increases the area of section of the air flowing access in the space between lower case 20 and inner shell 30.Air purifier is allowed to be made compact according to this air flow structure of the present utility model and pipeline configuration, simultaneously the loss of minimum air stream.
Then, the air stream moved up by fan 60 is guided by said structure, through the multiple through holes formed in photocatalytic filter 80, and then by dust collecting filter 90.
It should be noted that UV light emitting diode substrate 55 is placed on the bottom of inner shell 30, the height correlation of a part for this position and lower house 20, described part has relatively little diameter, and photocatalytic filter 80 and dust collecting filter 90 are arranged on the top of inner shell 30, the height correlation of this position and upper shell 10.In other words, according to the utility model, the diameter of inner shell 30 also increases at the At The Height of the stepped portion between lower house 30 and upper shell 10, and UV light emitting diode substrate 55 can be prepared into relatively little, and can be placed on and locate in a distance with photocatalytic filter 80, it is arranged in the small diameter portion of inner shell 30.Photocatalytic filter 80 can be made into slightly large, in order to maximize the area of ingress of air, it is arranged in the increase diameter parts of inner shell 30, and air pressure will frequently occur in the inside of dust collecting filter 90 reduces, it is also arranged on the increase diameter parts of inner shell 30, to increase the area of section of air by filter.Can see, when manufacturing compact air purifier, this structure of the present utility model is the structure that significantly can increase air purification efficiency.
Be directed to discharge portion 34 by the air of filter 80 and 90 by by streamlined diverging duct 382, and be discharged into outside.
Streamlined diverging duct 382 is formed as streamline-shaped, to reduce the area of section of air flowing, reduces the loss of air flowing simultaneously.At the superjacent air space of streamlined diverging duct 382, it is provided by this shape, can be used as PCB standing part 33.Control PCB is fixed to PCB standing part 33, and such air purifier can be operated, and its mode of operation can be examined at top simultaneously.The object of air purifier of the present utility model is assembling and in glass stand.Can see that the existence of action button is arranged at the top of air purifier, and the air venting direction of outwards leading from air purifier top, state when it preferably uses with the utility model is identical.Streamlined diverging duct 382 can reduce air flow losses, guides air to flow to and reaches narrow discharge portion, and ensure that the space that control PCB 51 places, make air purifier compacter by these.
Meanwhile, UV blocking radiation plate 39 is set below discharge portion 34, to stop that UV light is transmitted into outside from UV light emitting diode substrate 55 by discharge portion 34.Therefore, UV blocking radiation plate 39 can eliminate the misgivings of user to the adverse effect of UV light.
The position be inhaled into about air in air purifier of the present utility model and direction, air access portion is arranged on the top (below the stepped portion of upper shell 10 and lower house 30) of lower house 20 and leads forward.About position and the direction of discharging air from air purifier, air discharge portion divides and is arranged on top shell 40 and upwards leads.When entering part and discharge section are configured to spaced apart away from each other, and the different directions that leads as above, the discharge air after purification is prevented from again entering induction part.
In view of this is true, acetaldehyde and acetic acid, it is decomposed by air purifier, and it is heavier than air and therefore deposits, and air access portion is arranged on lower house 20, and air purification efficiency is improved further.
In addition, because air purifier of the present utility model is intended for use glass stand, air-inlet grille 212 is formed at the top of lower house 20, to suck air to be clean.In narrow space between lower house 20 and inner shell 30, define streamlined diverging duct 381 and air intlet 302, air enters inner shell 30 by air intlet 302, air intlet 302 is arranged on the both sides lower than streamlined diverging duct 381, be in dispersing on direction and in vertical direction, making minimum air flow losses of streamlined diverging duct 381.The area of section of the air flowing in inner shell 30 is also guaranteed by streamlined diverging duct 381.In these areas, can find out to achieve and be suitable for the size of air purifier and the air flowing access of state most.
The arrangement of air purifier filter
According to the order that the filter in air purifier of the present utility model arranges according to air flowing access, air is first through the carbon filter 70 that prefilter 72 and active carbon are made, to filter out in air the dust and absorption with bulky grain size and to remove noxious material (such as, ammonia and acetic acid).Then, acetaldehyde and ammonia and acetic acid are degraded by the light-catalyzed reaction of photocatalytic filter 80.Next, the dust collecting filter 90 that air passes through to be made up of fabric filter etc. to remove fine dust, and is then discharged.
The function of prefilter 72 is that pre-filtering is fallen large dust granule and is attached on photocatalytic filter 80 to stop foreign substance such as dust whereby, and the attachment of dust reduces the efficiency of photocatalytic filter 80.And, the function of active carbon be absorbing ammonia and acetic acid to increase the degradation efficiency of acetaldehyde, in the competitive reaction that photochemical catalyst causes, the reaction of acetaldehyde is than ammonia and acetic acid late (acetaldehyde is not easy to be absorbed by active carbon).
In addition, it should be noted that, the dust collecting filter 90 that maximum pressure drop occurs therein is arranged on the downstream of photocatalytic filter 80 to increase the pressure of the air stream contacted with photocatalytic filter 80, improves the efficiency of photocatalytic filter 80 ingress of air whereby further.
And, in the utility model, UV light emitting diode 57 for photo catalytic activation is arranged on the upstream of photocatalytic filter 80, such UV light can from the front of photocatalytic filter 80 (that is, the surface in the face of UV light emitting diode 57 of photocatalytic filter 80) exposure light catalytic filter 80.In this case, light-catalyzed reaction occurs from the front of photocatalytic filter 80 and the surface in contiguous front, before falling generation by air pressure during photocatalytic filter 80, further increase photocatalytic filter 80 by this and to degrade the efficiency of toxic gas.In addition, this arrangement can make dust collecting filter 90 be set directly at the downstream of photocatalytic filter 80, therefore makes air purifier more compact.In addition, UV light emitting diode 56 for sterilization is also arranged on UV light emitting diode substrate 55 of the present utility model, like this for the UV light of sterilization by irradiation to the dust collecting filter 90 being set directly at photocatalytic filter 80 downstream, kill the microorganism and germ that are filled into by dust collecting filter 90 whereby.Therefore, in this case, germicidal efficiency be significantly higher than UV light only irradiation air stream when germicidal efficiency.In addition, the UV light emitting diode for photo catalytic activation and the UV light emitting diode for sterilization are arranged on a single substrate, and this makes structure simple.
In addition, when UV reflecting plate (not shown) is arranged between the photocatalytic filter 80 of the inside of inner shell 30 and UV light emitting diode substrate 55, irradiation can be reflected to photocatalytic filter 80 to the UV light of the inside of housing 30, is further increased the efficiency of deodorizing and sterilization by this.
Relation between photocatalytic filter and UV light emitting diode
Figure 14 is the perspective view of the arrangement of photocatalytic filter 80 and UV light emitting diode substrate 55, and Figure 15 is the top view of photocatalytic filter 80.
With reference to Figure 14, the UV light emitting diode 56 for sterilization is arranged on the core of UV light emitting diode substrate 55, and arranges around UV light emitting diode 56 for three UV light emitting diodes 57 of photo catalytic activation.Especially, the UV light emitting diode 57 for photo catalytic activation will towards photocatalytic filter 80 irradiation UV light.
As shown in figure 15, photocatalytic filter 80 comprises: catalyst member 81, and it covers by sintering the TiO had on the ceramic porous material of hound's-tooth
2(titanium dioxide) obtains; With the elastic buffer 82 of the side of covering catalyst part.
Estimate the front of catalyst member 81 (namely, in the face of for the surface of the UV light emitting diode 57 of photo catalytic activation) and for photo catalytic activation UV light emitting diode 57 between distance the change of the flow behavior according to air is changed, arrive the area of catalyst member 81 and the function of irradiation level as the Distance geometry UV light between UV light emitting diode substrate 55 and photocatalytic filter 80.In view of this expectation is tested, and as a result, can see, in this case, wherein, the length (l) of the side of square light catalytic filter 80 is 5.5cm, when distance between light source 57 and the front (that is, in the face of the surface for the UV light emitting diode 57 of photo catalytic activation) of photocatalytic filter 80 is 2.5cm, the effect of sterilization is best, and when distance reduces to below 2cm or is increased to more than 3cm, the effect of sterilization can degenerate fast.
Distance between light source 57 and the front of photocatalytic filter 80 too little (below 2cm) time, the area of the part of the photocatalytic filter 80 of UV light irradiation reduces, but it arrives saturation state, wherein the efficiency of photo catalytic activation no longer increases, even if when the irradiation level of the UV light on the per unit area of photocatalytic filter 80 increases (the UV irradiation level related experiment of the Figure 16 that sees reference, it will describe subsequently).When UV light emitting diode substrate 55 is too near photocatalytic filter 80, air can not be easy to the central area (place of the main irradiation of UV light) flowing into photocatalytic filter 80, and the amount therefore contacting the air in photo catalytic activation this region the most incidental reduces.
In addition, time distance between light source 57 and the front of photocatalytic filter 80 too large (more than 3cm), in the unit are of photocatalytic filter 80, the irradiation level of UV light reduces with the degree reducing photo catalytic activation, and the air flowing between both is stable, it shows resemble laminar flow, shows that the air capacity that contact photocatalytic filter 80 shows reduces.
Meanwhile, when the length (l) of the side of filter is 4-7cm, the effect of deodorizing is good.If when the length of the side of filter is below 4cm, irradiation to the region not having filter, is illustrated that UV light is wasted by UV light, and if the length of the side of filter is more than 7cm time, by occur UV illumination penetrate less than region, illustrate that filter material and space are wasted.
Simultaneously, the voltage finding when the electric energy of supply UV light emitting diode 57 is below 5V or electric current when being below 200mA, the transmitting of light significantly reduces, show to need to use extra UV light emitting diode, and when the voltage of electric energy be more than 15V or electric current is more than 300mA, even if when electric energy increases, the transmitting of light also can not continue to increase.
Simultaneously, the present inventor has been found that the change of the deodoriging properties of photocatalytic filter 80 depends on the shape in the chamber formed in catalyst member 81, the width (g) in each chamber, the thickness (t) of the framework between chamber, the length of the side of catalyst member 81, the quantity (n) in the chamber of catalyst member, the height (h) of catalyst member, the direction (forward still reversion) of air stream, the sintering temperature of catalyst member 81 and time, for the peak wavelength of the UV light emitting diode 57 of photo catalytic activation and the irradiation level of the UV light in the front of arrival catalyst member 81.
Figure 16 is showing the figure of the degraded of the acetaldehyde of the function of the irradiation level of the UV light as the front arriving catalyst filter 80.
First, the change of the irradiation level of the UV light in the change of the deodoriging properties of photochemical catalyst and the front of arrival catalyst member 81 is detected repeatedly.As a result, can see, when the UV irradiation level of the unit are of photocatalyst surface is 14.67mW/cm
2time following, the deodorizing rate of photochemical catalyst increases along with the increase of UV irradiation level, but when UV irradiation level is higher than 14.67mW/cm
2time, deodorizing rate no longer increases.Especially, this trend is consistent, no matter the quantity (n) in the width (g) in each chamber 83, the thickness (t) of chamber framework, the length of the side of catalyst member, the chamber of catalyst member, the height (h) of catalyst member and the sintering temperature of catalyst member 81 and time.
In addition, the result of repeating test shows, when the UV irradiation level of the unit are of photocatalyst surface is lower than 10mW/cm
2time, the deodorizing rate of light-catalyzed reaction reduces rapidly, may be because the amount of light is sufficient not, and when the UV irradiation level of the unit are of photocatalyst surface is higher than 20mW/cm
2time, increase for the electric flux strengthening UV irradiation level, but significantly do not increased by the deodorizing rate of photo catalytic activation.
Figure 17 is showing the figure of the UV absorptivity of the photocatalytic filter 80 as the function of UV wavelength, and Figure 18 is showing the figure of the removing speed of the acetaldehyde under different UV wavelength.
About the UV absorptivity of photocatalytic filter 80, it can be seen in fig. 17 as the function of UV wavelength, and the UV absorptivity of photocatalytic filter 80 is the highest when the about 270nm of wavelength, and linearly reduces when wavelength is increased to 400nm.But can see the peak wavelength of the UV light emitting diode of use, it is 365nm that photocatalysis efficiency reaches the highest peak wavelength.This is because the luminous efficiency of UV light emitting diode.When the peak wavelength of UV light emitting diode reduces, the light launched from UV light emitting diode reduces rapidly.Therefore, in order to provide applicable UV irradiation level, it is use the surface with the photocatalytic filter 80 of the UV light emitting diode of low peak wavelength to need, and should use a large amount of UV light emitting diodes.But in this case, the increase of the size of substrate 55 is restricted, and due to the flowing of air, and cost increases sharply.In view of this fact is tested.The result of experiment shows, when use has the UV light emitting diode that peak wavelength is below 340nm, the odor removal efficient of photocatalytic filter 80 reduces rapidly.
And when use has the UV light emitting diode that peak wavelength is more than 380nm, the UV absorptivity of photochemical catalyst significantly reduces to the level being similar to conventional visible blue light, shows that the use of this UV light emitting diode is not so meaningful.
In addition, the result of experiment shows to have peak wavelength is the deodoriging properties that the use of the UV light emitting diode of 360-370nm can maximize photocatalytic filter 80.
Figure 19 is showing the figure that two have the acetaldehyde removing speed of the photocatalytic filter 80 of differing heights (h), and Figure 20 is showing the figure that two have the acetic acid removing speed of the photocatalytic filter 80 of differing heights (h).
The result of experiment shows, when photocatalytic filter 80 has the shape shown in Figure 15, the surface area of photochemical catalyst, its due to photocatalytic filter chamber between framework thickness (t) and increase, substantially the odor removal efficient of photocatalytic filter 80 can not be affected, but the height of photocatalytic filter 80 affects the inner wall area of interior air flow passage, therefore directly affect the contact area of air.
Therefore, can see, when the height of photocatalytic filter 80 is 5-10mm, the odor removal efficient of photocatalytic filter 80 is the highest.In addition, when highly reducing to below 2mm, photocatalytic filter 80 is difficult to use, because its faint intensity, and when being highly more than 15mm, only air drag increases, and UV light can not arrive the back part of photocatalytic filter 80 or its density becomes very thin, and therefore increase only cost and can not increase odor removal efficient.
Can see, when the width (g) in each chamber 83 is for 2mm, air drag can not increase, and the shaded area ratio having been blocked the inwall of the photocatalytic filter 80 that irradiation causes to its UV light by the shape of filter itself is not high, represent that the chamber width of 2mm is best suited for the UV light irradiated area ratio in the inwall maximizing photocatalytic filter 80.Meanwhile, when chamber width reduces to below 1mm, air drag increases, and the UV light quantity arriving inwall reduces, and shows that odor removal efficient is low.In addition, when chamber width is more than 4mm, the low entire area of inwall that causes of the density due to chamber 83 reduces, and shows that odor removal efficient is low.
About the chamber density relevant to the width (g) in above-mentioned each chamber, when chamber density lower than 30 chambeies/square inch or less time, chamber width is increased to more than 4mm, and inner wall area reduces, and shows that odor removal efficient is low.When the density in chamber is more than 260 chambeies/square inch, chamber width reduces to below 1mm, and air drag increases, and the UV light reaching inwall reduces, and shows that odor removal efficient is low.When chamber density is about 100 chambeies/square inch, air drag does not increase, and the shaded area ratio having been blocked the inwall of the filter that irradiation causes to its UV light by the shape of filter itself is not high, shows that odor removal efficient is the highest.
Experimental result about the frame thickness (t) in chamber shows, when frame thickness is below 0.3mm, and TiO
2layer becomes too thin, and therefore photocatalysis efficiency reduces, insufficient strength.When frame thickness is more than 1.2mm, but material consumption increases does not increase photocatalysis efficiency.In addition, when frame thickness is 0.6mm, photocatalysis efficiency is the highest.
Figure 21 is the figure of the deodoriging properties of display light catalytic filter 80, and it passes through 2gTiO
2to sinter and obtain for 1 hour, sintering temperature is different; Figure 22 is the figure of the deodoriging properties of display light catalytic filter 80, and it passes through 2.5g TiO
2sinter and obtain for 1 hour, sintering temperature is different; Be the figure of the deodoriging properties of display light catalytic filter 80 with Figure 23, it passes through 2.5g TiO at 400 DEG C
2sintering different time obtains, and sintering time is different.
As shown in figures 21-23, when sintering temperature is 350-450 DEG C, deodoriging properties is good, and when sintering time is that 1-2 is constantly little, the deodoriging properties of photocatalytic filter 80 is no problem.Can see, when considering the change of temperature, sintering temperature is 400 DEG C, if it is abundant not that sintering time is shorter than 1 hour sintering, if and when sintering time is oversize, the deodoriging properties of photocatalytic filter 80 can reduce instead of increase, and therefore sinters and preferably carries out 1-2 hour.
