Description
Technical field
The present invention relates to a kind of air purifiers, and more specifically it relates to a kind of such air purifier: it is in this way
It is compact make it possible in the cup holder for being mounted on vehicle, can effectively deodorization, collect dust and sterilization, and allow with simple
Mode replaces filter.
Background technique
Titanium dioxide (TiO2) there is high adhesion in the substrate of its covering, and it is (main when light activated light can be caused
If ultraviolet light) when being applied to thereon, it is shown that photocatalytic activity.
Particularly, in terms of the light-catalyzed reaction of titanium dioxide is for such as antibacterial and deodorization effectively, and therefore frequent
For air cleaning.For example, a kind of method for purifying air, wherein when air passes through photocatalytic filter, using UV light spoke
According to TiO2Photocatalytic filter (the TiO of covering2Ceramic foam filter) Lai Yinqi light-catalyzed reaction, this be it is a kind of in recent years
The air purification method being widely used.
Titanium dioxide is not single use, but is usually used with the state being covered in substrate.Therefore, titanium dioxide is covered
The shape of the photochemical catalyst of titanium is determined generally according to the shape of substrate.
It has been mainly used in using the deodorization of titanium dioxide in medium-sized and large-scale air-conditioning, but hardly for small-sized
Household Air Purifier in.
When strong UV light is occurred and provides big photocatalytic filter, there is large-size air conditioning high air to flow speed
Degree and area and its show deodorizing effect it is not especially difficult.
However, the size of photocatalytic filter and UV generator is limited in the case where small size air cleaner, and empty
Flow of air speed also reduces.Therefore, there is an urgent need to develop such air purifier, even in small-sized photocatalytic filter and
Certain level or higher deodoriging properties are also showed that under UV generator.Particularly, in Household Air Purifier, noise and energy
Consumption will be thought over.However, in the prior art, the development of air purifier concentrates on medium-sized and large-size air conditioning, and
For this reason that the technology for being suitable for new environment (such as family) is still inadequate.
If irradiating the photocatalytic filter of small size air cleaner with strong UV light for reinforcing effect, light is urged
The effect for changing filter cannot be guaranteed, and the material meeting rapid degradation or energy consumption in the region irradiated by strong UV light will
It is excessively increased.In addition, the UV light emitting diode of quantity and the short life of UV light emitting diode that installation increases will cause expense
Increase.
Further, although also can be expected to use be about with peak wavelength 270nm UV light emitting diode, it is known that
Most UV light can be increased the efficiency of air purifier, but cannot be said with peak wavelength about by Titanium dioxide absorption
For the deodorizing effect that the use of the UV light emitting diode of 270nm has been shown, because of the peak value wave emitted from UV light emitting diode
Long is about that power of the UV light of 270nm significantly than the UV light using peak wavelength for other values is faint.
In addition, new research has been carried out in terms of the shape or size to photocatalytic filter, even in small size
The effect of enhancing can be shown down, and related with the photocatalytic filter of UV light source.The shape of photocatalytic filter
Or size shows there is close ties with air drag, and can be used for the specification and property of the fan of small size air cleaner
It can must be defined.For this reason, for the normal function of small-sized air purifier, by reducing air cleaning
Air drag in device comes so that air flowing held stationary is important.
In addition, it is necessary to develop the method for preparing photocatalytic filter, the activation of photocatalytic filter itself can be enhanced
Effect.Without saying more, a kind of technology that the photocatalytic filter even by low capacity obtains high deodorizing effect be with
One of most desirable technology in the relevant technical field of small size air cleaner.
In addition, when preparing compact air purifier using UV light emitting diode and photocatalytic filter, fan and not
Same putting in order for filter will also be thought over.In medium-sized according to prior art and large-size air conditioning, dust is first
It is collected by dust collecting filter, and deodorization is then implemented by photocatalytic filter.Herein, filter is to reduce air
The biggest factor of flowing pressure, and be therefore not difficult to find out, it, will when photocatalytic filter is used for small size air cleaner
It shows and is used for same function in medium-sized or large-size air conditioning with it.
In addition, it is necessary to capture pathogenic bacteria entrained by the air in family.Always for filter or even bacteria removal
HEPA filter is the filter for significantly slowing air flowing, and for this reason that, it is difficult in small size air cleaner
Middle use.If the installation of HEPA leads to significantly slowing down for air flowing, its deodorization on the contrary that will affect photocatalytic filter
Function.For this reason, it may be necessary to another device is found, in the case where the air without substantially intervening in air purifier flows,
It can effectively bacteria removal.
It particularly, is to be badly in need of that there is high deodorization effect in the inner space of vehicle that the smell of wherein smoke from cigarette is difficult to clean up
The air purifier of rate.Because inner space of vehicle is very narrow, it needs to occupy little space or does not take up space
Air purifier, while there is the ability of significant purification air.Particularly because the frequent vibration of automobile, so air is net
Changing device should design in this way, so that even if may remain on fixed position in automotive interior, and can be with simple
Mode is installed.Particularly, it is provided as accessory by most motor corporations for the air purifier of automobile, and therefore bring is asked
Topic is that the air purifier used on a kind of automobile cannot be used for other automobiles.Therefore, related to automobile air purifier
Technical field in, to portable air purifier have high demand.
In addition, if air purifier is difficult to maintenance and repair or is difficult to make, since it is considered that its function, it can
Sale property be lowered, and its user will feel that it is not convenient.Therefore, it is necessary to the air purifier with simple structure,
And it should be easy to manufacture and convenient for safeguarding and repairing.

Such as Fig. 5, opening 215 is arranged on the side of right shell body 32 with such state, and wherein lower case 20 is connected to interior
Portion's shell 30.Its function is the access of the movement in order to ensure external cable, and external cable can be logical by external cable
Hole 322 is connected to the electric energy input connector 512 of control PCB 51, and can then be threaded through hole 13 and opening portion 215,
Space across right shell body 32 and upper housing 10 simultaneously extends to outside.
Electric energy input connector 512 can be made of socket, and the terminal (not shown) of external cable can be inserted into socket.Make
It is the replacement of external cable for convenience with the reason of terminal socket structure.For example, when air purifier of the invention is used for
When automobile, 12V DC cigarette lighter socket can be used, but when air purifier is used in family or office, can make
With 110V or 220V alternating current.Therefore, a possibility that replacing external cable is very high, and for this reason, external cable is excellent
Selection of land is connected to control PCB 51 using terminal socket structure.
It should be noted that the direction of terminal insertion is vertical with the direction that external cable is drawn out.In other words, external cable
Terminal is inserted into (horizontal direction) with diametrical direction, and the direction that external cable is drawn out is in downward direction.For this reason, such as
The terminal of fruit external cable be "" shape, the inside of upper housing 10 can on the direction that terminal connects support terminals, and because
This is also possible to prevent external cable abjection even external cable is pulled from outside.
The reasons why upper housing 10 and procapsid 21 are designed to the connection structure is to be able to only through separation upper casing
Body 10 replaces the dust collecting filter 90 of air purifier 90 without using separating tool.Particularly, with above-mentioned lock
Determine the opposite sequence of method, upper housing 10 is reversed rotation, and such locking projections 14 are deviate from from raised fixing groove 317, passed through
Click feel is raised and returns to raised holding tank 316.Under this state, upper housing 10 is downwardly drawn out, as shown in Figure 5.It is this
Under state, as shown in drawings, the part that dust collecting filter 90 is inserted into is exposed.Therefore, if only upper housing 10 is divided
From 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, such as Figure 10 institute
Show, and under this state, only the filter component 93 in frame 91 can be replaced.
In addition, procapsid 21 can be dismantled from back casing 22, no after upper housing 10 is separated as described above
It needs using separating tool.Therefore, as shown in figure 11, photocatalytic filter 80 and carbon mistake are replaced from the part of inner shell 30
Filter 70 be it is possible, the part by dismantle procapsid 21 expose.
Fig. 7-10 is that all external shells (upper housing, lower case and top shell) are separated by separation and carbon filter
The perspective view for the inner shell 30 observed from several directions afterwards, and Figure 11 is that air purifier of the invention is on only
Shell 10 and procapsid 21 separated in the state of perspective view.
About the inner shell 30 of air purifier of the invention, the front side of inner shell 30 has such front knot
Structure allows all dust collecting filters 90, photocatalytic filter 80 and carbon filter 70 to be inserted into and pull out.Therefore,
After upper housing 10 is separated, dust collecting filter 90 can pull dust to receive by the front of the exposure in inner shell 30
Collect the handle of filter 90 to replace.After procapsid 21 is separated, the positive photocatalysis of the exposure of internally positioned shell 30
Filter 80 can be drawn out.
As shown in FIG. 14 and 15, the catalyst member 81 in photocatalytic filter 80 has high hardness and brittleness, because
It is by being sintered TiO in grill-shaped ceramic bases2It obtains.Therefore, elastic buffer 82 is provided to surround catalyst
Part 81 is not impacted with guard catalyst part 81, and allows catalyst member 81 and inner shell 30 close each other
Connection.
TiO2The problem of photocatalytic filter 80 of covering is that photocatalysis efficiency reduces at any time, because foreign substance is attached
On the surface thereof.Despite the presence of this problem, filter will not be replaced frequently, be because of the expensive of it.Therefore, with mistake
The relevant technology of the regeneration of filter is constantly developed.Therefore, optical catalyst filter 80 needs mountable/dismountable
Structure is for replacing or regenerating.However, because photocatalytic filter 80 has a structure in which, wherein elasticity as described above is slow
It rushes device 82 to cover around catalyst member 81, forms the hand for installing or removing photocatalytic filter 80 from inner shell 30
Handle, just as dust collecting filter 90, this is intractable.For this purpose, in the present invention, as illustrated in figures 7-11, inner shell
30 only procapsids 21 are nonopen, but a part of a front surface and a side surface extended from front side, when photocatalytic filter 80
When being inserted into inner shell 30, it is open so that the front surface of photocatalytic filter 80 and a part of side can be exposed.
Due to the shape of inner shell 30, the two sides of photocatalytic filter 80 can be firmly grasped with hand, therefore photocatalytic filter 80 is held
It changes places pull-out.
Electric connection structure in air purifier
Inside cable has been sequentially formed on the surface of the left shell 31 of air purifier according to the present invention with reference to Fig. 8
Through hole 312, inside cable through slot 313 and inside cable guiding groove 314.In addition, inside cable through-hole 315 is formed in inner shell
The positive upper end of the fan containing section 301 of body 30.
Therefore, in order to from control PCB 51 to the inside cable that fan 60 and UV light emitting diode substrate 55 are powered from fixation
Control PCB 51 on PCB fixed part 33 passes in succession through inside cable through hole 312, interior along the outside of inner shell 30
Portion's cable through slot 313 and inside cable guiding groove 314, and inside cable through-hole 315 is passed through, thus into inner shell 30
Inner space.Inside cable into inner space is connected to the fan 60 that the lower part of inner shell 30 is arranged in, and further
Extend to be connected to UV light emitting diode substrate 55.In air purifier of the invention, inside cable passes through fan incorporating section
Divide the inner space of the 301 entrance inner shell 30 of inside cable through-hole 315, it is logical between exterior space and inner space
Road, and therefore inner shell 30 keeps airtight conditions, thus further increase efficiency that air stream accelerated by fan 60 (if
The other parts of inner shell 30 are perforated, and inside cable is inserted into the part, then the part flowed in inner shell 30 is empty
Gas can be flowed out by the gap between perforation and inside cable).
When seeing, it appears that inside cable readily can enter inner shell by the discharge portion 34 of inner shell 30
30, discharge portion 34 is arranged adjacent to control PCB 51.However, because the air flowing access in inner shell 30 is received by dust
Collection filter 90 and photocatalytic filter 80 are blocked, and the route by discharge portion 34 is impossible (if cable is by being somebody's turn to do
The air of route setting, inner shell 30 will be bypassed around cable, and therefore the air cleaning efficiency of clarifier will necessarily drop
It is low).In addition, as described above, the positive filter of inner shell 30 can be replaced.Therefore, in the present invention, internal electricity
Cable is connected according to above-mentioned route by the side of inner shell 30.
As shown in Figure 10, inside cable through hole 312 and external cable through-hole 322 are positioned away from filter pull-out direction
Direction on two sides.Therefore, as shown by the broken line in fig. 9, inside cable and external cable are connected to inner shell 30
Left and right side route.This structure significantly increases the utilization rate of the inner space of air purifier according to the present invention,
Inner space is very little, and should have the structure for connecting and dismantling filter in its front, and therefore of the invention
Air purifier can be made more compact.
Flow passage in air purifier
Figure 12 is showing the perspective view of air purifier according to the present invention, in the state in which, top shell
40, upper housing 10, back casing 22 and left shell 31 are removed, and Figure 13 is the perspective view of air purifier according to the present invention,
Itself in the state in which, wherein top shell 40, upper housing 10, back casing 22 and right shell body 32 are removed.
The flow passage of air purifier according to the present invention is as described below.Front housing is passed through by the negative pressure that fan 60 generates
Space of the air that the air-inlet grille 212 of body 21 sucks across lower case 20 and inner shell 30, and it is inhaled into fan 60
Suction part 61, pass through the carbon filter 70 and air intlet 302 of the two sides of the lower part of inner shell 30.Then, air from
Discharge portion 63 is discharged upwards by fan 60, is equably divided by movement-oriented device 37 and streamlined diverging duct 381
With pipeline configuration is entered, and move up.
When air moves up, movement-oriented device 37 is turned forward with streamline-shaped, and UV shines when its is upward
Diode substrate 55 slight inclination, the irradiation direction of the UV light emitting diode on substrate 55 upwards do not deviate photocatalysis substantially
In the range of filter 80.As can see in Figure 13 and 2, substrate 55 is set as flowing with the air that inner shell 30 is formed
Pipeline is spaced apart, and the flowing of such air can be naturally oriented to, and reduces the kinetic energy rejection of air stream whereby.
With reference to Figure 12 and 13, streamlined diverging duct 381 is had a structure in which, when its forward when its diameter gradually become
Greatly.Conversely speaking, by by air-inlet grille 212 from exterior guiding enter lower case 20 air have flow passage, when its to
The air intlet 302 that provides of lower part of inner shell 30 when advancing, flow passage is become larger by streamlined diverging duct 381.
In other words, the function of streamlined diverging pipeline 381 is the area of section for increasing the air flowing access in inner shell 30, also
Increase the area of section of the air flowing access in the space between lower case 20 and inner shell 30.It is according to the present invention to be somebody's turn to do
Air flow structure and pipeline configuration allow air purifier to be made compact, while minimizing the loss of air stream.
Then, it is guided by the air stream that fan 60 moves up by above structure, passes through shape in photocatalytic filter 80
At multiple through-holes, and then pass through dust collecting filter 90.
It should be noted that UV light emitting diode substrate 55 is placed on the lower part of inner shell 30, the position and lower case 20
A part it is highly relevant, the part has relatively small diameter, and photocatalytic filter 80 and dust collecting filter
90 are arranged on the top of inner shell 30, and the position is highly relevant with upper housing 10.In other words, according to the present invention, interior
The diameter of portion's shell 30 also increases at the height of the stepped portion between lower case 30 and upper housing 10, and UV shines
Diode substrate 55 can be prepared into relatively small, and can be placed on photocatalytic filter 80 at a distance, set
It sets in the small diameter portion of inner shell 30.Photocatalytic filter 80 can be made into slightly larger, in order to maximize ingress of air
Area, be arranged in the increase diameter portion of inner shell 30, and the inside of dust collecting filter 90 will be frequent
Air pressure, which occurs, to be reduced, and the increase diameter portion of inner shell 30 is also disposed at, to increase the section face that air passes through filter
Product.It can be seen that this structure of the invention is can to dramatically increase air cleaning effect when manufacturing compact air purifier
The structure of rate.
Air by filter 80 and 90 is directed to discharge portion 34 by streamlined diverging duct 382, and is arranged
It is put into outside.
Streamlined diverging duct 382 is formed as streamline-shaped, to reduce the area of section of air flowing, while reducing sky
The loss of flow of air.It in the upper space of streamlined diverging duct 382, is provided by the shape, may be used as PCB fixed part
33.Control PCB is fixed to PCB fixed part 33, and such air purifier can be operated, while its mode of operation can be
Top is examined.The purpose of air purifier of the invention is assembly and is used in cup holder.It can be seen that the top of air purifier
There are the presence of operation button, and the air emission direction being outwardly directed at the top of air purifier in portion, preferably makes with the present invention
The state of used time is identical.Streamlined diverging duct 382 can reduce air flow losses, and guidance air stream reaches narrow exhaust
Part, and ensure that the space that control PCB 51 is placed, make air purifier more compact by these.
Meanwhile UV ray barrier plate 39 is set below discharge portion 34, to stop UV light from UV light emitting diode substrate
55 are emitted to outside by discharge portion 34.Therefore, UV ray barrier plate 39 can eliminate user to the adverse effect of UV light
Misgivings.
About the position and direction that air in air purifier of the invention is inhaled into, air access portion is arranged on down
It the top (below the stepped portion of upper housing 10 and lower case 30) of shell 20 and is oriented to forward.About from air purifier
The position and direction of air are discharged, air discharge portion, which sets up separately, to be set in top shell 40 and be upwardly directed.When entering part and discharge
Part is configured to be spaced apart away from each other, and is oriented to different directions as described above, and purified discharge air is prevented from
It is again introduced into induction part.
In view of the fact that, acetaldehyde and acetic acid are decomposed by air purifier, heavier than air therefore deposit, empty
Gas entering part is arranged in lower case 20, so that air purification efficiency further increases.
In addition, air-inlet grille 212 is formed in the upper of lower case 20 because air purifier of the invention is intended for use in cup holder
Portion, to suck air to be clean.In narrow space between lower case 20 and inner shell 30, streamlined diverging is formd
Pipeline 381 and air intlet 302, air enter inner shell 30 by air intlet 302, and air intlet 302 is arranged below
On the two sides of streamlined diverging duct 381, on the diverging direction in streamlined diverging duct 381 and in vertical direction, so that
Minimize air flow losses.The area of section of air flowing in inner shell 30 is also by streamlined diverging duct 381
It is guaranteed.In these areas, it can be seen that realize the air flowing for being most suitable for size and state for air purifier
Access.
The arrangement of air purifier filter
The sequence that filter in air purifier according to the present invention is arranged according to air flowing access, air are worn first
Carbon filter 70 made of prefilter 72 and active carbon is crossed, to filter out dust and the absorption in air with bulky grain size
And remove noxious material (for example, ammonia and acetic acid).Then, acetaldehyde and ammonia and acetic acid are by the light-catalyzed reaction of photocatalytic filter 80
Degradation.Next, air the dust collecting filter 90 made of fabric filter etc. to remove fine dust, and connect
Be discharged.
The function of prefilter 72 is that pre-filtering falls big dust granule to prevent foreign substance such as dust to be attached to whereby
On photocatalytic filter 80, the attachment of dust reduces the efficiency of photocatalytic filter 80.Moreover, the function of active carbon is to absorb
Ammonia and acetic acid are to increase the degradation efficiency of acetaldehyde, and in the competitive reaction caused by photochemical catalyst, the reaction of acetaldehyde is than ammonia and second
Sour evening (acetaldehyde is not easy to be absorbed by the activated carbon).
Nevertheless, it should be recognized that the dust collecting filter 90 that maximum pressure drop occurs inside it is arranged on photocatalysis
The downstream of filter 80 further increases photocatalysis to increase the pressure of the air stream contacted with photocatalytic filter 80 whereby
The efficiency of 80 ingress of air of filter.
Moreover, in the present invention, the UV light emitting diode 57 for photo catalytic activation is arranged on photocatalytic filter 80
Upstream, such UV light can be from the front of photocatalytic filter 80 (that is, photocatalytic filter 80 faces UV light emitting diode
57 surface) irradiation photocatalytic filter 80.In this case, light-catalyzed reaction will be from the front of photocatalytic filter 80 and neighbour
Nearly positive surface takes place, and before the air pressure drop when passing through photocatalytic filter 80 occurs, is further increased by this
Photocatalytic filter 80 is degraded the efficiency of toxic gas.In addition, this arrangement can be such that dust collecting filter 90 directly sets
It sets in the downstream of photocatalytic filter 80, so that air purifier is more compact.In addition, the UV light-emitting diodes for sterilization
Pipe 56 is also disposed on UV light emitting diode substrate 55 of the invention, will be irradiated for the UV light of sterilization to being set up directly in this way
On the dust collecting filter 90 in 80 downstream of photocatalytic filter, kill whereby be filled by dust collecting filter 90 it is micro-
Biology and germ.Therefore, in this case, germicidal efficiency is significantly higher than the effect of the sterilization in the case that UV light only irradiates air stream
Rate.In addition, the UV light emitting diode for photo catalytic activation and the UV light emitting diode setting for sterilization are on a single substrate,
This makes structure simple.
In addition, when UV reflecting plate (not shown) be arranged in inner shell 30 inside photocatalytic filter 80 and UV shine
When between diode substrate 55, the UV light irradiated to the inside of shell 30 can be reflected to photocatalytic filter 80, pass through this
Further improve the efficiency of deodorization and sterilization.
Relationship 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 photocatalysis
The top view of filter 80.
With reference to Figure 14, the central part of UV light emitting diode substrate 55 is arranged on for the UV light emitting diode 56 of sterilization
On, and be arranged for three UV light emitting diodes 57 of photo catalytic activation around UV light emitting diode 56.Particularly, it is urged for light
The UV light emitting diode 57 for changing activation will irradiate UV light towards photocatalytic filter 80.
As shown in figure 15, photocatalytic filter 80 includes: catalyst member 81, is covered on by sintering with cage
TiO on the ceramic porous material of pattern2(titanium dioxide) obtains;With the elastic buffer of the side of covering catalyst part
82。
It is expected that catalyst member 81 front (that is, in face of for photo catalytic activation UV light emitting diode 57 surface) and
The distance between UV light emitting diode 57 for photo catalytic activation will change according to the variation of the flow behavior of air, as
The distance between UV light emitting diode substrate 55 and photocatalytic filter 80 and UV light reach the area and spoke of catalyst member 81
The function of illumination.Expect to be tested in view of this, and as a result, it can be seen that, in this case, wherein square
The length (l) of the side of shape photocatalytic filter 80 is 5.5cm, when the front of light source 57 and photocatalytic filter 80 is (that is, face
The surface of UV light emitting diode 57 for photo catalytic activation) the distance between be 2.5cm when, the effect of sterilization is best, and works as
When distance is reduced to 2cm or less or increases to 3cm or more, the effect of sterilization can quickly degenerate.
As the distance between the front of light source 57 and photocatalytic filter 80 too small (2cm or less), the light of UV light irradiation
The area of the part of catalytic filter 80 is reduced, however it reaches saturation state, and wherein the efficiency of photo catalytic activation is not further added by,
Even if (the UV irradiation level phase for the Figure 16 that sees reference when the irradiation level of the UV light on the per unit area of photocatalytic filter 80 increases
Experiment is closed, will be later described).When UV light emitting diode substrate 55 is too close to photocatalytic filter 80, air cannot
The central area (place that UV light mainly irradiates) of photocatalytic filter 80 is readily flowed into, and therefore contacts photo catalytic activation
The amount for being easiest to the air in the region occurred is reduced.
In addition, as the distance between front of light source 57 and photocatalytic filter 80 too big (3cm or more), photocatalysis
The irradiation level of UV light is reduced to reduce the degree of photo catalytic activation, and the air stream between the two on the unit area of filter 80
It is stable for moving, and shows as laminar flow, shows that contacting the air capacity that photocatalytic filter 80 shows is reduced.
Meanwhile when the length (l) of the side of filter is 4-7cm, the effect of deodorization is good.If the one of filter
When the length of side is 4cm or less, irradiation to the region of not filter, is illustrated that UV light is wasted, and if filter by UV light
The length of side when being 7cm or more, by occur the irradiation of UV light less than region, illustrate that filter material and space are wasted.
Meanwhile finding when the voltage of the electric energy of supply UV light emitting diode 57 is 5V or less or electric current is 200mA or less,
The transmitting of light substantially reduces, and demonstrates the need for using additional UV light emitting diode, and when the voltage of electric energy is 15V or more or electric current
When for 300mA or more, even if the transmitting of light will not continue growing when electric energy increases.
Meanwhile the inventors have discovered that the variation of the deodoriging properties of photocatalytic filter 80 depends on catalyst member 81
The shape of the chamber of interior formation, the width (g) of each chamber, the thickness (t) of frame between chamber, catalyst member 81 side length
It spends, the direction of the quantity (n) of the chamber of catalyst member, the height (h) of catalyst member, air stream (forward or reversion), urge
The sintering temperature of agent part 81 and time, for photo catalytic activation UV light emitting diode 57 peak wavelength and reach catalysis
The irradiation level of the positive UV light of agent part 81.
Figure 16 is showing the acetaldehyde of the function of the irradiation level as the positive UV light for reaching catalyst filter 80
The figure of degradation.
Firstly, the irradiation level of the positive UV light of the variation and arrival catalyst member 81 of the deodoriging properties of photochemical catalyst
Variation is detected repeatedly.As a result, it can be seen that when the UV irradiation level of the unit area of photocatalyst surface is 14.67mW/cm2
When following, the deodorizing rate of photochemical catalyst increases with the increase of UV irradiation level, but when UV irradiation level is higher than 14.67mW/cm2
When, deodorizing rate is not further added by.Particularly, this trend is consistent, no matter the width (g) of each chamber 83, chamber frame thickness
(t), the length, the quantity (n) of the chamber of catalyst member, the height (h) of catalyst member of the side of catalyst member and catalysis
The sintering temperature of agent part 81 and time.
In addition, repeat test the result shows that, when photocatalyst surface unit area UV irradiation level be lower than 10mW/
cm2When, the deodorizing rate of light-catalyzed reaction reduces rapidly, it may be possible to because the amount of light is not sufficient enough, and work as photocatalyst surface
Unit area UV irradiation level be higher than 20mW/cm2When, the electric flux for enhancing UV irradiation level increases, but is urged by light
The deodorizing rate for changing activation is not significantly increased.
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 aobvious
The figure of the removing speed of the acetaldehyde under different UV wavelength is shown.
It can see in Figure 17, light is urged about the UV absorptivity of photocatalytic filter 80 as the function of UV wavelength
The UV absorptivity of change filter 80 highest in wavelength about 270nm, and linearly reduced when wavelength increases to 400nm.However,
It can be seen that the peak wavelength of the UV light emitting diode used, it is 365nm that photocatalysis efficiency, which reaches highest peak wavelength,.This is
Because of the luminous efficiency of UV light emitting diode.When the peak wavelength of UV light emitting diode is reduced, emit from UV light emitting diode
Light reduce rapidly.Therefore, in order to provide suitable UV irradiation level, to use the UV light emitting diode with low peak wavelength
Photocatalytic filter 80 surface need, it should use a large amount of UV light emitting diode.However, in this case, substrate
The increase of 55 size is restricted, and due to the flowing of air, and cost increases sharply.In view of the fact that tested.Experiment
The result shows that, when the use of there is peak wavelength being 340nm UV light emitting diode below, the deodorization of photocatalytic filter 80
Efficiency is reduced rapidly.
Moreover, when the use of there is peak wavelength being the UV light emitting diode of 380nm or more, the UV absorptivity of photochemical catalyst
It is significantly reduced to be similar to the level of conventional visible blue light, shows that the use of the UV light emitting diode is not so significant.
In addition, experiment the result shows that can be most with the use of UV light emitting diode that peak wavelength is 360-370nm
The deodoriging properties of big photocatalysis filter 80.
Figure 19 is showing the figure of the acetaldehyde removing speed of two photocatalytic filters 80 with different height (h), and
Figure 20 is showing the figure of the acetic acid removing speed of two photocatalytic filters 80 with different height (h).
Experiment the result shows that, photocatalytic filter 80 have shape shown in figure 15 in the case where, photochemical catalyst
Surface area, due to the frame between the chamber of photocatalytic filter thickness (t) and increase, have substantially no effect on photocatalysis
The odor removal efficient of filter 80, but the height of photocatalytic filter 80 influences the inner wall area of interior air flow passage, because
This directly affects the contact area of air.
Thus, it can be seen that when the height of photocatalytic filter 80 is 5-10mm, the deodorization effect of photocatalytic filter 80
Rate is highest.In addition, photocatalytic filter 80 is difficult with when being highly reduced to 2mm or less, because of its faint intensity,
And when height be 15mm or more when, only air drag increase, UV light cannot reach photocatalytic filter 80 back part or
Its density becomes very thin, and therefore increases only cost without can increase odor removal efficient.
It can be seen that air drag not will increase, and by filter itself when the width (g) of each chamber 83 is 2mm
The shaded area ratio that shape has blocked the inner wall of photocatalytic filter 80 caused by UV light of the irradiation to it is not high, indicates 2mm
Chamber width be most suitably adapted for maximizing the UV light irradiated area ratio of the inner wall of photocatalytic filter 80.Meanwhile when chamber is wide
When degree is reduced to 1mm or less, air drag increases, and the UV light quantity for reaching inner wall is reduced, and shows that odor removal efficient is low.In addition, chamber is wide
When degree is 4mm or more, since the low entire area for leading to inner wall of the density of chamber 83 is reduced, show that odor removal efficient is low.
About chamber density relevant to the above-mentioned width (g) of each chamber, when chamber density lower than 30 chambers/square inch or
When less, chamber width increases to 4mm or more, and inner wall area is reduced, and shows that odor removal efficient is low.When the density of chamber be 260 chambers/square
Inch or more when, chamber width be reduced to 1mm hereinafter, air drag increase, and reach inner wall UV light reduce, show deodorization imitate
Rate is low.When chamber density is about 100 chambers/square inch, air drag does not increase, and is blocked by the shape of filter itself
The shaded area ratio of the inner wall of filter caused by UV light of the irradiation to it is not high, shows odor removal efficient highest.
Frame thickness (t) about chamber the experimental results showed that, when frame thickness is 0.3mm or less, TiO2Layer becomes
It is too thin, and therefore photocatalysis efficiency is reduced, intensity is inadequate.When frame thickness is 1.2mm or more, material consumption increases but does not have
There is increase photocatalysis efficiency.In addition, the photocatalysis efficiency highest when frame thickness is 0.6mm.
Figure 21 is the figure for showing the deodoriging properties of photocatalytic filter 80, by by 2gTiO2What sintering obtained for 1 hour,
Sintering temperature is different;Figure 22 is the figure for showing the deodoriging properties of photocatalytic filter 80, by by 2.5g TiO2It is small to be sintered 1
When obtain, sintering temperature is different;It is the figure for showing the deodoriging properties of photocatalytic filter 80 with Figure 23, by 400 DEG C
By 2.5g TiO2Sintering different time obtains, and sintering time is different.
As shown in figures 21-23, when sintering temperature is 350-450 DEG C, deodoriging properties are good, and when sintering time is 1-
At 2 hours, there is no problem for the deodoriging properties of photocatalytic filter 80.It can be seen that when considering the variation of temperature, sintering temperature
It is 400 DEG C, is sintered and is not enough if sintering time is shorter than 1 hour, and if photocatalysis is filtered when sintering time is too long
The deodoriging properties of device 80 can reduce rather than increase, therefore are sintered and preferably carry out 1-2 hours.
