Abstract

An airborne-bacteria filter arrangement is used with an apparatus that has an internal airflow. The airflow passes through a fibrous filter arrangement that has, on its fibres, a highly toxic bacteria-killing substance which entraps and kills bacteria in the airflow. A charcoal-infused filter removes the toxic substance from the airflow, and further filters can effuse beneficial substances to the airflow. The filter arrangement is sealed from germ intrusion. The filter arrangement is used in hand dryers and other apparatus such that the airflow can be sterilised to the extent of achieving 100% bacteria removal.

Description

Modified sterilising filter arrangement, equipment and method

Technical field

The improvement of the assembly that the present invention relates in indoor equipment, use, this equipment have internal gas flow and are discharged into indoor people's the environment of an activation from this equipment.

One aspect of the present invention relates to especially for the improvement of the air-flow that discharges from this indoor equipment being carried out the filtration device structure of sterilization.

Other preferred aspects of the present invention include and help realize from air-flow, removing this clarification of objective of 100% bacterium.

Other aspects of the present invention also relate to the improved equipment that discharges air-flow, special hand dryer, hair dryer, vacuum cleaner, fan, air-conditioning, refrigerator, the tumble dryer of still not relating to uniquely.

Background technology

Bacterium is through the diffusion of gas flow equipment

Known indoor equipment sucks air and then air is discharged to as air-flow in indoor people's the environment of an activation, therefore is the equipment of propagating microorganism, bacterium and virus.As a result, the people just contacts with the bacterium that comes to spread everywhere through the air of being discharged by equipment under this environment more easily.

For example, prior art comprises a large amount of dried hand equipment, discharges current of warm air and is used for dried hand.Generally suppose that all the use of this dried hand equipment is a health.But the dried hand equipment that unexpectedly, it is found that these prior aries is actually a kind of approach that spreads microorganism.

Reason is that to carry a lot be the bacterium of carrier with the air to the current of warm air itself from the dried hand equipment of these prior aries.This is to suck air because hand dryer carries from the lavatory in the environment of a lot of bacteriums, and discharges air-flow warm, breed bacteria to user's wet hand.

And many people can not be placed on their hand the long enough time under the current of warm air so that dry their hand fully.As a result, user's warm wet environment on hand is well suited for being blown to by hand dryer the rapid breeding of bacterium on hand.

Many miniature organism in the air-flow is not killed by the heating element heater of hand dryer.And, be vegetative ecotopia from the heating installation body of hand dryer.As a result, these live bacterias are directed to the user on hand.In fact, in fact this hot air blower that it is found that prior art has increased by 500% with bacterial number.

Problem less than 100% removal of bacteria

Although the dried hand equipment of this prior art has acceptance widely in such as communal facilitys such as public lavatories; But use these equipment to be resisted in some field; Particularly such as medical fields such as hospital and clinics, and in child care center and food service industry.

For example, when the surgeon uses antibacterial liquid or soap to wash one's hands before undergoing surgery, if the surgeon prepares his wet hand of oven dry in the current of warm air of the dried hand equipment of prior art, if surgeon's hand is by bacterium subinfection then to wash one's hands be useless again.

In addition, in the new millennium, virologist and public health official predict that following mortality influenza and other viral world wides are very popular, and employed wording is when can take place, rather than whether this epidemic disease possibly take place.When this global epidemic disease takes place, can expect in the indoor equipment that discharges air-flow, to remove 100% bacterium.Otherwise this equipment even can remove for example 90% bacterium, also can become the instrument of the popular mortality virus of diffusion particularly in public places.In other words, at epidemic period, 100% bacterium is removed becoming extremely important.

Prior art comprises and is used for killing bacteria and/or removes the gas flow equipment that degerms from the air-flow of equipment, but in reality, this known product can not removed 100% bacterium from the air-flow of equipment, particularly uses through long-term.

Although the part bacterium in the air-flow can killed or remove to this prior art, the final goal of 100% removal of bacteria remains matchless.

Therefore; Beginning at this specification; Compare with the current goal of from air-flow, removing 100% bacterium, declare to kill or remove degerm and its actual performance for example only can realize from air-flow, removing 80% and even the equipment of the prior art of 90% or 95% bacterium between have obviously difference.

Target is to be faced with the different obstacles that in the prior art that need not realize 100% removal of bacteria target, can not address for the invention of removing 100% bacterium.

Prior art

In the prior art, attempted making gas flow equipment can produce the current of warm air that killed bacterium.The main development zone in this field concentrates on the use of ultraviolet ray (UV) ray, kills the bacterium in the air-flow with attempt.But unexpectedly, it is not good to have proved that the UV ray kills in the task of air-flow bacterium effect in execution.

At first, must be remembered that even the UV ray is to kill most of bacterium, the fact is that all the other bacteriums in the air-flow still can arrive the user on hand, and the beginning with minute speed breed.

Secondly, some microbiologists think in fact killing bacteria not of UV ray, and only are the sterilization bacteriums, and just UV just stops bacteria breed or breeding.If really be like this, mean that then the current of warm air that discharges from the hand dryer that is equipped with UV still includes the unhygienic composition of live bacteria.

The final degree of health, 100% removal of bacteria just is for the application particular importance of operation or medical aspect.Say from this respect, by laboratory tests that the inventor carried out show current on the market some be equipped with ultraviolet hand dryer can not kill 100% bacterium in the release air-flow.

Therefore, the adversary implements often to be not inclined in the vital medical use of strict sterilization standard the dried hand equipment that uses prior art, particularly orthopaedic surgical operations operation this part, and in the wound medical treatment.

Another problem is, through several weeks, some months even after several years, microorganism can accumulate in device interior.Because air-flow is inhaled into equipment, through the use that continues, a large amount of bacteriums constantly are drawn in the machine.In other words, machine constantly is exposed to bacterium with contacted all inner surfaces of air-flow.After after a while, machine intimate can become bacterial origin.Behind machine switched off, perhaps when it did not generate air-flow, inner bacterium can continue growth and breeding.When the equipment of prior art can not 100% removal of bacteria, then those remaining bacterias still remained in the equipment, so the inner surface of equipment becomes bacterial origin after after a while.

The air-flow that the equipment of other types also is used for discharging through them is on indoor diffusion bacterium.For example, air-conditioning sucks air, or from outdoor or from indoor environment, and then air-flow is discharged to indoor.Like this, if not 100% bacterium that kills or remove in the air-flow of from air-conditioning, discharging, then maybe be after after a while, the bacterium in the gas of indoor environment will build up.

As another example, vacuum cleaner from the floor or the surface suck bacterium when sucking particle.Although the filtration of vacuum cleaner systems can filter out particle from air-flow, the bacterium particulate is arranged still in air-flow.They are diffused into the indoor environment by the air-flow that discharges from vacuum cleaner.

Can in other gas flow equipments that suck and discharge air-flow, see the same phenomenon of bacterium diffusion.These comprise for example hair dryer, fan and dryer.Under the situation of dryer, the air that carries bacterium is inhaled into from indoor environment, and is directed to clothing.

Even refrigerator suction air, and discharge the condensation chamber that the air that carries bacterium gets into refrigerator, food is exposed to bacterium.

One of target of several aspects of the present invention provides one or more characteristics, they separately or its combination can make the equipment that discharges in the environment of an activation that gas flows to the people in leaving the air-flow of filter, realize 100% bacterium decline.

Another target of the present invention is to overcome or improve one or more problem of the prior art, and the modified replacement scheme of prior art perhaps is provided.

The discussion of the prior art in this specification should not be counted as the approval of the state of skilled person's in this field conventional, well-known general knowledge or replenish.

Hand dryer 1 sucks to give vent to anger side by side and flows in the environment of an activation of the frequent visiting of people, such as the lavatory, or the washroom in the hospital, just give some instances here.

Hand dryer 1 is suitable for discharging or discharges the air-flow that adds hot-air 200C through sterilization fully to be used for dried hand.In this instance embodiment, the working range of hot-air is approximately 55 to 65 degrees centigrade.

Hand dryer 1 has the base portion that comprises main cover 10 and substrate 11 forms.Substrate 11 and can be seen in Fig. 2 A and 2B in Figure 1B and 1C best.

In Figure 1B, cover 10 is installed on the substrate 11 through hinge 12.

The design of hinge 12 makes cover 10 or to remove from substrate 11 disengagings.This can install hand dryer 1 with simple two step processes: at first, substrate 11 is installed to such as on the vertical surface such as wall, and secondly, cover 10 is connected on the hinge of substrate 11.

Substrate 11 is fixed on the wall through screw 13, screw or other suitable mechanism of ammonium fixation.

Figure 1A shows the cover 10 that is positioned at the closed position, and it is the structure when hand dryer 1 is installed in this position.

Figure 1B shows the cover 10 that is positioned at open position.

In Figure 1A and 1B, the direction of the hand dryer of being painted 1 is the direction when being installed on the wall.

In gyp embodiment, cover 10 is locked on the substrate 11, and requires private key 16A to come lock 16B is carried out release, shown in Figure 1A and 1B.

Air-flow

Generally speaking, when using hand dryer to come hand to the user to carry out drying, get into or suck in the frame, successively it is heated then and discharge from the air of surrounding environment.The path of this air-flow is symbolically with the arrow 200A among Figure 1A, the arrow 200C among the arrow 200B among Figure 1B and last Figure 1A representes then.Certainly, the actual airflow in the hand dryer 1 is more complicated and chaotic, therefore, in order to explain conveniently it is reduced to

arrow

200A, 200B, 200C.

Air heater

In Fig. 4, hand dryer 1 has heating element heater 300 this form of heating regime devices.Heater 300 is positioned on the opening part of fan housing 400, and in the independent bottom perspective view of the fan housing 400 of Fig. 4, shows clearlyer.

Heating element heater 300 comprises and is suitable for the electric wire grid or the metallic plate that when hand dryer 1 ejection thermal current, carry out electric heating.

For Figure 1B and 4, heating element heater 300 is positioned at

frame

10 and 11 inside, and is used for heating air flow 200B, so that air is enough warm, with dry user's hand.

Inlet device

Hand dryer 1 has inlet device, and in use air gets into

frame

10 and 11 and transfer to heating element heater 300 through it.

In an embodiment, inlet device is counted as zone or passage, and air transfers to heating element heater 300 through it.

In Figure 1B, inlet device comprises a large amount of assemblies and the characteristic among the embodiment of Figure 1B.At first, inlet device comprises the

second filter assemblies

520A, 520B and 520C, and air gets into frame through it.

Inlet device comprises that also the porous of

frame

10 and 11 is inner.Air the flow through

second filter assemblies

520A, 520B and 520C get into the inner inside of porous of

frame

10 and 11 then.

Inlet device also comprises main-inlet 405, is positioned at the side of fan housing 400.In this main-inlet 405, inserted the filtration device structure (and below tell about other embodiment) of the bacterium that the primary air of

main filter assemblies

410A, 410B and this form of 410C propagates.

The decomposition view of first embodiment of

main filter assemblies

410A, 410B and 410C is as shown in Figure 3.

Fig. 4 shows the embodiment of main filter assemblies, and it is engaged in the main-inlet 405 of fan housing 400.

In Fig. 4, under the preferable case, main filter assemblies comprises base element 410A, and it directly is engaged in main-inlet or the main aperture 405.In Fig. 7 B, base element 410A has several elastic hooks 408, is used to make base element and main aperture 405 engagements and pinning.

Fig. 3 shows the decomposition view of the parts of

main filter assemblies

410A, 410B and 410C.

In Fig. 3 and 4, the bacterium of filter material 410B form catches filter for installation and is connected to filter mounting 410C.Filter mounting 410C can mesh with base element 410.

Filter material 410B has the slit, is used for filter is contained in filter mounting 410C.In use, can see from Fig. 4 and in Fig. 7 B, see the most clearly that protruding bolt 411 on the filter mounting 410C passes the slit in the filter.

Each of filter mounting 410A and 410C all has scalping 414, and this has also limited moving of filter material 410B.

Base element 410A and filter mounting 410C have corresponding bayonet socket installing component, are used to make these parts to be combined together with the mode of bayonet type engagement.In other embodiments, can use the mesh mechanism of other forms or style, for example interior dress bolt perhaps is press-fitted to install perhaps to press to lock and installs.

Outlet device

Hand dryer 1 has outlet device, and air sprays as thermal current 200C through it after being heated element 300 heating, is used to dry hand.

In an embodiment, outlet device is counted as air and leaves heating element heater 300 up to discharging zone or the passage that is passed through from hand dryer 1.

In Figure 1A, heating element heater 300 is positioned at the inside of the outstanding horn shape opening 14 of cover 10 fronts.Therefore, in instance embodiment, pass the distance of inlet device institute warp with air and compare, outlet device is very short on overall distance.

The hot-air of heating element heater 300 of flowing through almost just leaves frame after passing opening 14.

Opening 14 has grid, is used to prevent the heater block of user's finger Contact Heating element 300.

Fan

As can be seen from Figure 4, air-flow 200A, 200B and the 200C through hand dryer 1 creates through the air-flow generating apparatus of rotary fan 401 this forms.The form of fan 401 is the blade in fan housing 400 inner rotations.In Fig. 4, can see the inside of ring-type fan 401.Usually, ring-type fan housing 400 holds ring-type fan 401.See that in Figure 1B the rotation of fan 401 is by motor 430 operations.In this example, motor is 125 watts, the general-purpose motor of 7500rpm.The outer cover of motor 430 is sealed, and gets into the air-flow in the fan housing 400 to prevent bacterium via any slot in the outer cover of motor 430.

The rotary fan 401 that is arranged in fan housing 400 is applicable to the air of fast moving as air-flow.Air-flow gets into frame via initial second hole 520D and its

secondary filter assembly

520A, 520B and 520C; The porous of then passing

frame

10 and 11 is inner; Then pass main aperture 405 and pass

main filter assemblies

410A, 410B and 410C, arrive heating element heater 300 up to air-flow.Then, the air-flow or the air stream that produce through fan 401 are discharged from frame as the thermal current 200C that can be used in the hand of drying the user.

The position of main filtration device structure

The inlet device of hand dryer 1 comprises " main-inlet " of at least one main aperture 405 form.This main aperture is counted as unique inlet of air and bacterium entering fan housing 400.

The notion of " main-inlet " is that all air-flows from the hand dryer ejection must pass main-inlet at last for the first time.In an embodiment, if all air in the air-flow that from hand dryer, comes out must pass completely through hole or inlet at certain on a bit, then opening is defined as " main aperture " or " main-inlet ".

Place on said one or more main-inlet through effective bacterium being caught filter, can guarantee that all air-flows that from hand dryer, come out are all caught filter by bacterium and intercept and capture.

In an embodiment, main aperture 405 is positioned on the fan housing 400.Main aperture 405 is the openings in the fan housing 400, must pass this last filter 410B so that get into all air of fan housing 400.After air-flow gets into fan housing, only there is an outlet 14 of equipment 1.Therefore, so this main aperture 405 is counted as " main-inlet ", because get into the inlet of fan housings except this has other.In other words, there are not other paths of leading to last outlet 14.

Below explanation can let the definition of " main-inlet " easier, for example, owing to exist many other paths to let air get into this equipment, so the inlet of the secondary among Figure 1A 520D can not be counted as " main-inlet ".For example, when cover 10 was opened, bacterium can be walked around secondary filter 520D, and perhaps when cover 10 was closed, bacterium even the slot that can pass through in cover 10 and the substrate 11 got into.For example, when cover 10 was opened, the indoor gas that carries disease germs in the toilet poured in the inside of this equipment 1.In addition, at inlet 520D and exporting at last between 14, in the inside of equipment 1, have a large amount of inner surfaces, it can and become the source of bacterium by infection having used several months or several years after.Secondary filter 520B can not intercept and capture the extra bacterium that gets into air-flows through such as other channels such as the cover of opening or inner surface, but last main filter 410B can block this extra bacterium.Here it is why secondary inlet 520D be not regarded as " main-inlet " and why secondary filter 520B be not regarded as the reason of " main filter ".

In Fig. 4, can see the main-inlet of main aperture 405 forms.In the explanation of Figure 1B, this main aperture 405 is blocked, and this is because the

main filter assemblies

410A, 410B and the 410C that are shown have been inserted in the main aperture 405 in the fan housing.

This

main filter assemblies

410A, 410B and 410C blocked air-flow before air-flow arrives heating element heater 300.Main aperture 405 for the air-flow in all hand dryers if from hand dryer, discharge the point that must pass.Here, bacteria particles is caught at last, and therefore intercepts its entering fan housing 400.Under the preferable case, outer cover 400 and other parts of 430 are sealed, so that air can not for example get into through motor outer cover 430.

Through

main filter assemblies

410A, 410B and 410C being placed on the last point that gets into fan housing, it is as last possible defence line.This guarantee the bacterium that might rest in the air-flow intercept through main filter 410B.Even bacterium is unexpectedly through the slot in the wall of equipment or because the long-term bacterial buildup of device interior gets into machine; This bacterium can not be discharged through exhaust jet stream 200C from grid 15, and this is because any air-flow that leaves equipment all must pass main

filtration device structure

410A, 410B and 410C at last.

Therefore, the identification of the position of the main filtration device structure at last inlet point 405 places of main-inlet and fan frame is that a kind of equipment that helps is in the characteristic that from the air-flow 200C of drying equipment 1 ejection, realizes 100% removal of bacteria and elimination.

We know, in the prior art, also are potential this problems of bacterial origin if do not consider to solve the inner surface of device interior, then will realize very difficulty of 100% removal of bacteria.Each inner surface of device interior and parts all are potential pollution sources.For example, the surface of interior lacquering can emit toxin, and air-flow also possibly cause the internal part fragment that after using the several years, comes off.In the prior art, the filter that is positioned at the very forward place of air flow path can not stop the bacterium that comes out from the inner surface in the downstream of filter.

Therefore; In the present embodiment; Main filter 410B last under the preferable case is located immediately on the fan frame, so as all these be in extra pollutant and the bacterium at the air-flow upper reaches can be before getting into the fan frame by last and main

filtration device structure

410A, 410B and 410C institute's intercepting and blocking-up.Before air-flow arrived the heating element heater 300 and the port of export 15, main filtration device structure was positioned on the last possible position.(place the inside of fan frame inconvenient filter, this is because filter is not easy to be replaced, and the filter that is not easy to be replaced self possibly become pollution sources after using a period of time)

In the present embodiment, main aperture 405 and relevant main

filtration device structure

410A, 410B and 410C all are positioned at the inside of equipment rack 10 and 11.This has guaranteed that the user can not contact main filter assemblies, and only to allow professional authorized person to contact and change.

In other are revised; Existence is positioned on the fan housing 400 more than one or more main aperture 405; But in this modification embodiment, all air that still need get into fan housing 400 must pass these and be positioned at the one or more main apertures 405 on the fan housing.

In the present embodiment; Even bacterium will get into through the slot in the

frame

10 and 11; The position of main filter 410B on the fan housing just gets into unique inlet of fan housing, has guaranteed that this main filter 410B can block the bacterium that all get into fan housings 400.

In the embodiment of Figure 1A and 1B, main-inlet 405 is arranged in the inlet that leads to the air-flow generating apparatus, perhaps in other embodiments, if all air that get into the air-flow generating apparatus all pass this final approach, then can change its physical location.

In an embodiment, main aperture (or a plurality of main aperture) only is positioned at or is connected to fan housing 400, so that all air-flows that get into fan housing all must pass this main aperture.This is preferred and optimum position, shown among the embodiment of Figure 1A.

Another Consideration of design present embodiment is can not to conduct interviews from the outside of hand dryer 1 under the main aperture preferable case as the main and unique opening that gets into fan housing 400.For example, the main aperture 405 that gets into fan housing 400 can not conduct interviews from the outer surface of cover 10, otherwise just can let the dried hand equipment 1 of unwarranted user capture moving-member and be connected with the parts of electric wire.This also for the saboteur in the motor-driven parts of equipment, be inserted with harmful substances in addition in fan and motor water filling chance is provided.All these possibilities all possibly endanger the user of hand dryer 1.

Bacterium catches

Bacterium is actually by atomic little microscopic particles to be formed.The hand dryer 1 of present embodiment has bacterium and catches filter for installation.In other words, this device is used to catch bacteria particles, so that in fact the air of ejection is not with bacteria particles from hand dryer 1.Emphasis not only is killing bacteria, also is to catch bacteria particles.

In the present embodiment; In Fig. 3; The bacterium of

main filter assemblies

410A, 410B and 410C catches filter for installation and comprises filter material 410B; It is fiber quality, fine and close, common uneven filter material matrix, and it is enough fine and close, can block and catch the bacteria particles of the overwhelming majority in the air-flow.These fibers are as stopping the physical obstacle that bacteria particles is passed through.

In the present embodiment, find in routine is used, for example in common communal bathroom facility,, therefore will just change filter material 410B every other month in the ideal case owing in filter material, can accumulate bacteria particles.

Filter material

In exemplary preferred embodiment, filter material is the non-woven fiber material that mixes.Owing to find that its weave of textile material is closeer, compare easier restriction air-flow with non-woven fiber material, thereby be not suitable for, so adopt non-woven fibre under the preferable case.

Filter material among the embodiment of Figure 1A is nonwoven, pin felt, polyester fiber packing material, and it has following characteristic:

Weight (gsm)	150	ISO?9073-1：1989
			Thickness (mm)	1.4m～1.8mm	ISO?9073-2：1995
Tensile strength (N/50mm):--vertically--horizontal	165 165	ISO?9073-3：1989
			Air permeability (l/sec/m ²)	2,500	ISO?923020cm ²/200Pa

In another preferred sample of filter material, air permeability is confirmed according to Australian Standard AS2001.2.34-90.The result is that the air permeability that the preferred sample of filter material has is 234.7cm3/cm2/sec, and the coefficient of variation is 5.9.

The polyester fiber property matrix of filter material for mixing, it has the weaving matrix of completely random or with method of weaving.Therefore, the bacteria particles of passing in the air-flow of this fibrous matrix must be passed tortuous air flow path through at random fibrous matrix the time, therefore increased the possibility that each bacteria particles strikes one of fiber or caught by fiber.

Usually, adopting fine and close filter to owe fine and close filter to guarantee selecting to exist compromise between these two conflicting requirements of air-flow faster to help bacterium to catch still to adopt.

Problem is: bacteria particles has more effectively been caught in the density of filter or the increase of thickness on the one hand, but has also reduced the air-flow through filter simultaneously, and this can cause that fan motor is overheated.Therefore, if want to realize the selected objective target of 100% bacterium blocking-up, then need carry out the appropriate density that some test the filter material that finds the motor that is applicable to the certain power among the given embodiment and fan.For example, produce the more powerful fan of air blast, can adopt the bigger or thicker filter material of density through employing.

The screen pack weight of calculating with gsm (every square metre gram number) can demonstrate the character of average-size of the slot of screen pack.

For example, we find that the fibrous matrix of 50gsm caught bacteria particles fully, but the fibrous material of 50gsm can not provide sufficient air-flow for fan 401.

In the prior art, exist through selecting very meticulous screen pack to realize the trend that bacterium is filtered.Theory of the prior art is similar with the idea of the fishing net that is used to fish, and wherein the size of mesh must be fully little, is complementary with the size with bacterium.This can cause the decline owing to mesh size, the problem that the ability that air-flow passes through at a high speed also descends thereupon.Owing to do not recognize and the very meticulous relevant problem of filter mesh size, in the prior art of the very meticulous sterilizing filter of known employing, be not easy to find this problem.

Present embodiment has been recognized the problem of conflicting needs.On the one hand, need the filter mesh to be enough to catch bacteria particles, but on the other hand, mesh again can not be too little so that hinder best air-flow.

In the present embodiment, mesh size is chosen as about 150 microns weaves, that is to say that average slot or the hole between the fiber of non-woven material is approximately 150 microns.This is from realizing that between this size field quick air-flow can guarantee again to select the large-scale filter material of 100% bacterium capture ability simultaneously.Use because filter is the viscous liquid coating on being positioned at filter, make and use 150 microns relatively large weaves of this hole dimension to become possibility, be described below.

Under the situation of bound by theory not, can suppose in the prior art that it is because the mean size greater than bacteria particles is wanted significantly in the hole of 150 microns weaves that 150 microns weaves are not considered to be used for suitable width of mesh that bacterium catches.But; In the present embodiment; We think that when fiber is coated with the toughness antibacterial liquid near the mesh size that is chosen in 150 microns is suitable, and this is because bigger hole allows quick air-flow; And the random airflow path that can present enough complications simultaneously, this can guarantee that 100% bacterium can impinge upon that one of fiber is gone up and can be owing to viscous coating sticks on it.

Therefore, select about 150 microns weave to use different mechanism to catch bacterium.Bacterium not necessarily only is between the slot of two adjacent fibers, to catch (fishing net that is similar to fishing).But we find that the weave of 150 microns fibrous matrix provides enough winding raods footpath, and this makes that the probability of bacterium and fiber collision or collision is high.In addition, as described below, fibre bundle scribbles cohesive material, more likely be attached on the fiber to guarantee the bacteria particles that bumps against with filter fiber, rather than along with air-flow advances.In other words, in 150 microns filter mesh, the big slot in the fiber can make air-flow pass filter material fast.Simultaneously, 150 microns fibre density has guaranteed that along with air passes filter, airborne bacterium is filtered the device fiber and catches.

In other words, being that the speciality of fibrous material and the viscous coating gang on the fiber solve i) bacterium catches and ii) this a pair of contradiction requirement of air velocity.

Certainly; Though the filter about 150 microns is widely used on market, adopts the filter mesh about 150 microns to come to realize simultaneously i) 100% bacterium catches and ii) higher this beyond thought result of air velocity remains the selection that a kind of past do not predict.Why selecting the mesh about 150 microns is because big hole dimension is the doubly a lot of of common bacteria size unexpectedly.In fact and unexpectedly optimal selection the selection of present embodiment proves, if combine use with viscous coating, seems that then very big filter mesh.

Can carry out some tests, confirming acceptable upper and lower bound, the form with the positive and negative deviation at 150 microns places makes and still can realize i) 100% bacterium catches and ii) very high this dual and unexpected target of air velocity.

Main filter 410B catches and holds back the most bacteria particles in the air-flow in filter.Therefore, the air-flow that leaves main filter 410B compares when getting into filter 410B more aseptic.

In the preceding paragraph, word " is held back " bacterium that refers to the overwhelming majority and has been got into, but can not leave filter.In other words, leave the air-flow of main filter 410B and compare, have quantity bacteria particles still less with the air-flow that gets into main filter 410B.

The air-flow that leaves filter 410B that is characterized as of the present embodiment of having verified through independent microbiology test is 100% not to be with bacterium fully, and is perhaps at least almost aseptic and approach 100% target terrifically.In other words, bacteria particles is only deactivated or is killed, but largely by physical property from air-flow get rid of.

The early stage experimental model of present embodiment is in the male sex washroom of factory, to test, and wherein checking is to have the air pollution that has different microorganisms.Find at last that from hand dryer 1 air-flow 100% of ejection is not with bacteria particles or pathogen.Therefore, the bacterium of present embodiment catches filter for installation can catch the bacterium in the air-flow in 100% ground, therefore leave the air-flow that bacterium catches filter for installation to be, or aseptic near 100% fully.

Therefore obviously, the embodiments of the invention that can realize 100% aseptic dried hand target when dried hand demonstrably even than disposable paper handkerchief health more.For example, can realize that model near 100% removal of bacteria also is applicable to promptly will carry out operating surgeon.

Therefore, of the present invention aspect this in, the embodiment of hand dryer 1 has the device that is used to catch and hold back actual bacteria particles, so that prevent that bacterium from leaving hand dryer and getting among the thermal current 200C.This is having employed air cleaner in the hand dryer now in conceptive being different from; Existing air cleaner only is to filter out such as bigger particles such as the dust and the grains of sand, and is not suitable for even does not expect and will catch bacterium with the standard of 100% removal bacteria particles.Therefore, only told about " air cleaner " only if any prior art told about the actual acquisition of bacteria particles, then its initial target just can not must be regarded as bacterium is caught the formerly open of filter for installation.

The broad sense prerequisite of present embodiment is for effective killing bacteria, must catch bacteria particles.This method with existing sterilization hand dryer is different, and these sterilization hand dryers are attempted at first not caught and hold back bacteria particles on bacterium by killing bacteria in the air-flow of the fast moving transmission.In experiment; We find; The EXPERIMENTAL EXAMPLE of the present embodiment that kills with the bacterium that is hunted down that at first catches bacterium and then can not in filter, move is compared, and this existing technical system is very different in the validity of from air-flow, removing the bacterium this respect.

In a word, fibrous matrix can be caught to physical property bacteria particles, and also air-flow is demonstrated minimum obstruction simultaneously.Therefore, remarkable size greater than bacterium is wanted in average slot between the fiber or hole, to hinder air-flow as far as possible littlely.In addition, fibrous matrix is that air-flow has been created the winding raod footpath, impinges upon at least some fibers of fibrous matrix so that bacteria particles has high possibility.

The example of filter material

As an example, employed in the present embodiment filter material is a combing spunbond polyester film, has the multiple random fiber of every square meter 150 grams.The measurement thickness of filter material is 1.4～1.8mm.In the 150gsm filter material, this is 2500l/sec/m than the maximum air velocity permeability that macropore allows ²

In drying regime, it is about 30～40 microns fibre matting that this material provides average slot or hole.Therefore, in drying regime, this material will realize that it is inadequate that 100% bacterium catches, and this is because bacteria particles is generally 0.3～30 micron, and virus is between 0.01～0.05 micron.Therefore, in its drying regime, 150gsm filter material self can not realize 100% or near the target of 100% capture rate.But, when the viscous coating on the binding fiber, select this obviously too big mesh size but can realize the target of 100% capture rate unexpectedly, can also make air-flow simultaneously fast through bigger hole.

Compare with the capture rate of the normal, expected that only adopts 150 microns hole dimensions to extrapolate, the viscosity of newly-increased coated fiber makes the ability of catching particle strengthen manyfold.

Fungicidal substance: the bacterium in the filter is killed

In a preferred embodiment, filter material 410B scribbles the Fungicidal substance that can kill the bacterium that wherein is hunted down and holds back.

Fibrous matrix has poisonous Fungicidal substance on its fiber, it can kill any bacterium on any Fungicidal substance that impinges upon on the fiber.

Therefore, on the fiber of filter, also killed the bacterium of the overwhelming majority that in filter, is hunted down and holds back.If (in filter, do not have anti-biotic material, then catch bacteria particles and can cause the bacterial infection in the filter material)

The advantage of present embodiment is to catch germ or bacterium, when they are in the filter, it is killed then.Otherwise iff is caught bacterium and it is not killed, and then the bacteria levels in the filter can increase along with the time gradually.Then, when machine switched off or shut-down operation, the bacterium on the filter can grow, so filter self can become bacterial origin, makes bacterium spread to entire equipment, thereby infects inner surface.

When the anti-biotic material that is used for killing bacteria kills the role of the bacterium that filter catches in execution, can be liquid or gel.

In fact in the present embodiment, Fungicidal substance is directed onto on the fiber filter modulator material with the form of alcohol-based liquid spraying.When alcohol vapored away, Fungicidal substance rested on the fiber random matrix.

In the present embodiment, Fungicidal substance is that liquid is executed material.When Fungicidal substance was applied on the fiber as liquid, it formed viscous coating on fiber, was used to help to catch the bacterium on the Fungicidal substance that impinges upon on the fiber.Viscous coating can physically remain to the bump bacteria particles on the fiber, so that bacterium is fixed on this position and kills.

What deserves to be mentioned is that the anti-biotic material of any kind of or liquid may be used to kill the bacteria particles of in

filter

410B and 520B, being caught.In the present embodiment, this material is by Healthguard Corporation of Campbellfield, and Victoria, Australia make, and production number is AFA-BK, 9-260.

In the present embodiment, because the antibiotic cohesive material on the filter may not keep its validity after a period of time, catch filter 410B and should change in every month.

Another modification: filtration device structure

In first embodiment of Fig. 4, in main filter assemblies, there is a main filter 410B.In this first embodiment, though anti-biotic material has killed the bacterium that impinges upon on the filter 410B, its defective is that the anti-biotic material of trace can stay in the air-flow, and will leave in the environment that filter gets into the mankind's activity environment.Though these micro-anti-biotic materials unlikely threaten the general population, for some particularly suffer from the people of breathing problem or tuberculosis, but be highly dangerous.For example, the people who suffers from the cystic fibrosis disease possibly receive in the atmosphere even the harm of the toxic material of trace.

Anti-biotic material can kill 100% usually the most during the level of the bacterium of severe toxicity when being in, and also is poisonous and harmful to the people usually.For example, might stimulate eyes.

For killing bacteria, Fungicidal substance requires to have very high toxicity, but this toxin need be got rid of from air-flow under the preferable case.

In order from air-flow, to remove the toxic material of any trace, Fig. 7 A and 7B show the principal fiber filter 410B with poisonous Fungicidal substance and have active carbon or carbon filter device successively.That in the present embodiment, the activated carbon filtration apparatus adopts is notes NACF or the porous filtering modulator material 410D that is marked with active carbon or carbon granule.

In annotating activated carbon filtration modulator material 410D, active carbon or carbon granule block or remove any poisonous Fungicidal substance that derives from the coating of catching on the filter 410B from air-flow.This has guaranteed that the air-flow that leaves main filter assemblies does not almost not only contain bacteria particles, nor contains the Fungicidal substance of trace.

As stated, from air-flow, remove Fungicidal substance and make that equipment 1 can be with in the mankind's activity environment that has the responsive crowd of lung therein, for example hospital.

In addition, owing to from air-flow, removed Fungicidal substance, so this allows on the first fabric filter 410B, to use Fungicidal substance more efficiently.Do not have active carbon filter 410D subsequently if this is, maybe the personnel in the surrounding environment be worked the mischief, therefore need in the first filter 410B, limit and use highly toxic material owing to worry the severe toxicity in the air-flow.And when adopting active carbon filter 410D subsequently, use the higher material of toxicity can make equipment in its sterilizing ability, realize bigger validity at the first filter 410B.In the present embodiment, because of existing active carbon filter can use the higher material of toxicity to help to realize that the air-flow 100% from equipment 1 ejection is aseptic.

And then, under the situation of bound by theory not, can believe that active carbon carries out oxidation again to air-flow when airflow passes is annotated active carbon filter 410D.

Therefore, active carbon has double action, at first removes poisonous antimicrobial chemical material, secondly air-flow is reoxidized.Active carbon also can be removed foul smell and smell from air-flow.

In the present embodiment, fiber filter modulator material 410D has been injected into activated carbon granule or powder, but revises among the embodiment at other, if loose structure does not hinder air velocity basically, then also can use the more active carbon of pore or annotate absorbent charcoal material.

In the present embodiment, active carbon filter 410D master catches and killing bacteria if it were not for being used for.Catch among the filter 410B first and to carry out the step that is used to catch with killing bacteria.Therefore, should arrive 100% aseptic level, perhaps get into intimate at least this level that is in active carbon filter 410D place at air-flow from the air-flow of catching filter 410B.

In fact, active carbon or carbon catch and killing bacteria aspect do not have advantage.Under the situation of bound by theory not, active carbon is not a kind of suitable substrate that is used to place Fungicidal substance, and this possibly be because Fungicidal substance is adsorbed to the inside of activated carbon granule, but not lets Fungicidal substance stop from the teeth outwards to be used for killing bacteria.In addition, suppose that it is liquid or to have applied the Fungicidal substance of liquid in the present embodiment that activated carbon granule possibly pollute.In a word, the active carbon filter 410D in the present embodiment and be not suitable for the step of carrying out killing bacteria.

Because active carbon filter 410D does not comprise viscosity antibacterial liquid coating in the present embodiment, therefore, air-flow just should realize that 100% removes bacterium from air-flow before arriving active carbon filter 410D.If no, mean that then some bacteriums possibly arrive active carbon filter, and this bacterium, air-flow possibly breed when not working.This can cause after a period of time, and active carbon filter is transformed into bacterial origin.Therefore, before air-flow arrives active carbon filter, must remove bacterium in 100% ground.

Filter frame-bacterium can not get into

In second embodiment of Fig. 7 A, (be similar to the situation of Fig. 4), the base element 410A of filter assemblies is suitable for being directly installed in the main-inlet or main aperture 405 of fan housing.

In the decomposition view of Fig. 7 A, the first filter mounting 410C is installed on the base element 410A, and the second filter mounting 410E is installed on the first filter mounting 410C thereupon.

Fig. 7 B shows and is in the assembly of assembled state among Fig. 7 A.Assembled part is installed together with the bayonet type engagement, but also can adopt other forms of connection mechanism in other embodiments.

In Fig. 7 B, arrow 409 shows the direction of air-flow when use equipment 1.In Fig. 7 B, filtration device structure has the filter barrier device, and this device comprises the wall of filter mounting in an embodiment, when filter mounting is assembled, installs very closely.It also comprises the barrier of being created by the interface of base element 410A lower limb and fan frame.

The wall of filter mounting 410C and 410E is when being incorporated into when using together, as holding main catch filter 410B and active carbon filter 410D.The net effect of filter barrier device is to provide bacterium impermeable barrier for filter 410B and 410D.The impermeable barrier of this effective bacterium separates

filter

410B and 410E with the inside of equipment.This means when air-flow is blown over equipment 1, even that when air-flow is not blown over the bacterium of device interior or other pollutants can only get into filtration device structure via the face of the main filter 410B of the air-flow of directly facing into.Pollutant and bacterium can not pass the miscellaneous part or the junction of filtration device structure.

In the embodiment of Figure 1A to Fig. 4,

filtration device structure

410A, 410B, 410C, 410D and the 410E of airborne bacterium is positioned at the inside of equipment 1 fully.

When base element 410A and

filter frame

410C and 410E are installed together, because by the impermeable barrier of the bacterium that close installation produced of assembly, bacterium can not get into the inside of filtration device structure through the abutment of

assembly

410A, 410C and 410E.This is a kind of advantage, because the same with any machine, the inner surface of equipment 1 all is potential pollution sources, is from the used material of manufacture component no matter pollute, although come from the bacterium that wherein exists protection still to get into machine.Therefore, bacterium impermeable barrier has prevented bacterium (side or the binding site of 410A～410E) has got into through filter assemblies.

In addition, the impermeable barrier of identical bacterium has prevented that when closing device did not perhaps produce air-flow, the inner any viable bacteria of filtration device structure escaped the inside into this equipment.For example, in Figure 1A, bacterium possibly get into through grid 15.For example, when not using this equipment, the impermeable barrier of bacterium prevents that the bacterium access arrangement is inner.This has been avoided device interior itself finally to become bacterial origin.(when closing machine, main filter 410B prevents that the bacterium via passage 14 entering of relative tail end from arriving the interior zone of equipment.In case open once more and use equipment, any bacterium of tail end passage 14 all can be killed by the heat from heating element heater 300)

In the surface of filtration device structure, creating the impermeable barrier of bacterium has replenished and has been used for separately and/or the function of other characteristics of these equipment that prevent that as much as possible the bacterium access arrangement is inner of combining.This has been avoided or has reduced the situation that the inside self of drying equipment 1 wherein possibly become bacterial origin to greatest extent.

Reducing these inner characteristics of bacterium access arrangement to greatest extent helps equipment 1 to realize that successfully 100% gets rid of bacterium from air-flow.In other words, even when this equipment does not produce air-flow, prevent that bacterium from getting into inside also is to influence another factor whether entire equipment can realize 100% removal of bacteria target.

As stated, main in the present embodiment filtration device structure 410A～410E is positioned at the final approach place of fan frame 400.In conjunction with this fact, be that main filtration device structure provides the impermeable barrier of bacterium only to guarantee further that except through the front portion of main filter 410B, bacterium can not pass main aperture 405 through slot in the filter assemblies or binding site.

In other revise embodiment, can be designed for the mechanism that the parts with filter assemblies are installed together, so that in case after installing, these assemblies can not be unpluged by the user.The locking mechanism of some forms can be provided.This has guaranteed that the user can by mistake not open filter assemblies, thereby discharges bacterium wherein.For this embodiment of the present invention, whole filter assemblies 410A～410E needs whole periodic replacement.In the present embodiment, the suggestion filter assemblies was changed once at least in every month.

Note, in some cases, particularly in non-medical environment, can not be strict with the use active carbon filter.The crowd who is in common health status can stand the Fungicidal substance that contains trace in the air-flow in spraying to ambient atmosphere.

Integrated unit: change and abandon filter and assembly thereof

Through Fig. 3,7A, 7B, 8A, 8B and 1B, filtration device structure is in the form of complete individual unit after assembling.In other words, all associated components of filtration device structure all are comprised in the replaceable and discardable unit.When main filter 410B began to be full of the bacteria particles of catching and killing, whole main filtration device structure can be used as an integral body and removes and change.This is a kind of advantage, when filter begin by the bacteria particles of catching and killing when blocking, can be easily more the change owner filter assemblies guaranteed that himself can not become bacterial origin.Not only the fabric filter material require is changed, and can also be needed by its peripheral components that bacterium infected to change.The equipment that is installed in dispersedly in the machine as the prior art of separation assembly at assembly does not have this advantage.

Integrated unit: the inner surface of replacing and drop device

The ability of removing and change individual unit also has another advantage.It not only can change

filter cell

410B and 410D, and it is also important that, it can also remove and change " inner surface " 412 near the equipment 1 at metapore 405 final approach places.This has guaranteed that these inner surfaces 412 itself can not covered by bacterium or other pollutants after having used several months or several years.

This has proved that Equipment Design must consider that assessment used the potential performance after the several years, and is not only the function when it is very new.After several years, the inner surface of machine possibly also polluted by bacterium.This for the equipment that can use the several years after long-term the use, realize 100% from air-flow the difficulty of removal bacterium increased another factor.

Therefore, the inner surface that can change near the equipment of metapore 405 is to help to realize 100% removal of bacteria in the present embodiment, is not only in new equipment and after using the several years, another factor.

In prior art equipment, can remove though spread all over the assembly of equipment, be difficult to change inner surface.Therefore, in the present embodiment, the sealed environment of creating in the main filtration device structure can be used as that single unit is removed and replacing is an advantage.Important inner surface towards metapore can be changed at an easy rate.This has guaranteed after a period of time, can not become bacterial origin as the inner surface in the downstream of catching filter 410B at last itself.

In Fig. 7 B, 8B, 9A and 9B, the main filter 410B that catches is separated by the capacity region with capacity slot 413 this forms with notes active carbon filter 410D.Slot 413 is sealed within the impermeable barrier of bacterium.Capacity slot 413 is caught the interim destination that is got into after the filter 410B as air-flow leaving.Under the situation of bound by theory not, the capacity slot 413 of this qualification helps air-flow is remained within the localized area, rather than a large amount of diffusion, and this can increase the air sinuous flow and reduce air velocity.

When not having air-flow to pass, main catch filter 410B and annotate that active carbon filter 410D normally is parallel to each other so that therebetween capacity region be put down with tabular.

Air-flow leaves main filter 410B and the entering notes active carbon filter 410D of catching, and its mode is that air-flow is vertical basically with the surface of each filter for installation.

In Fig. 7 A, the brim height of each filter assemblies has been confirmed the distance of the slot 413 between each filter assemblies.We know, the distance between the filter assemblies can influence the flow through ability of whole filtration device structure of air.Reason is that

identical filter material

410B and 410D is placed to together, and as the heavy parting of single filter material and clearance seam not, this can not realize the identical speed of air-flow.

Active carbon filter 410D should be relatively near catching filter, so that can block the antibiotic toxic materials that all come autonomous filter 410B basically.Otherwise; If active carbon filter 410D with catch filter 410B and separate very big distance; Then after the several years, can see that toxicity antimicrobial chemical material stably is deposited on the inner surface on the inner surface in main equipment of catching between filter 410B and the notes active carbon filter 410D.Therefore, slot 413 is more little good more.Little slot 413 has been guaranteed almost to get into active carbon filter 410D immediately from the air-flow that main filter 410B comes out, and this probability that makes the toxicity antibacterial liquid be deposited on the inner surface of equipment is less.

Injecting substances

Brief review once, air-flow gets into filtration device structure via catching filter 410B, in catching filter 410B, the antibacterial liquid that bacterium is painted on the fiber is caught and is killed.Next, successively, the air-flow that comes out from filter 410B gets into notes active carbon filter 410D, and any micro-antibacterial liquid in the air-flow is removed herein.

Among the 3rd embodiment of Fig. 8 A and 8B, follow two

filter

410B and 410D closely, in the 3rd frame 410G, can also accommodate the release filter for installation of this form of spray filter 410F.

The purpose of this spray filter 410F is in air-flow, to increase or inject some the useful property released materials.For example, but useful injecting substances can be the medicine that can take to the user with the mode that air is carried secretly.In an example, medicine can be by the employed medical substance of the people that suffer from asthma.Usually, the people that suffer from asthma use inhalator, and with the medicinal steam of inspiration, but, embodiments of the invention can be used for this material is injected atmosphere on every side, so that can suck medicine continuously with more small dosage.This method can be used for other disordered breathings, for example bronchitis and nasosinusitis.Potentially, any suck the minor ailment that steam treats through people can be through this surge be taken medicine in air.

Under the optional situation, but useful injecting substances can be a fragrance.The environment that is used for having tedious foul smell when equipment 1 for example during communal bathroom, need be injected into material with fresh air in the atmosphere, and this just becomes of great use.This can be applied to the aromatotherapy field especially.

In medical field or other washrooms under the situation of employed hand dryer; Even under the hypertoxic Fungicidal substance preferable case that main filter 410B comes out, should from air-flow, get rid of, but this spray filter 410F subsequently can spray and catch the extremely toxic substance that filter 410B go up to exist and compare the less relatively antibacterial material of toxicity.When user's hand was dried, the less material of this toxicity can be directed onto the user on hand.This just is the portable extra antibacterial treatment that supplied.

In the present embodiment, use has also been carried out extra task from the less antibacterial material of toxicity that spray filter 410F discharges, and is used to kill or minimize the amount of bacteria via tail end opening 14 access arrangements 1.

Be described below, each the useful property released material can combine chemoreleaser to use.

The vibration filter

Fig. 9 A and 9B show its middle filtrator and are installed in the inner embodiment of its filter frame, and Fig. 9 A is the situation that does not have air-flow, and Fig. 9 B is the out-of-date situation of air communication.

In the present embodiment, aforesaid filter is the form that loosely is mounted to the flat pieces filter material of pin 411.Loose being installed in of filter makes filter in air-flow, to tremble on the pin, illustrate like Fig. 9 B.Under the situation of bound by theory not, we know, the vibration of spray filter 410F help the property released material from the fiber jet of filter 410F to air-flow.

Acceptable filter sequence and combination

Various embodiment of the present invention has multiple acceptable filter sequence and/or combination.

In all embodiment of filtration device structure, it is essential that main bacterium is caught filter 410B.

For the specific medical environment; And exist therein even the master of trace is caught in other human environments of an activation of the very sensitive people of employed hypertoxic antibacterial material among the filter 410B, catching under the preferable case after the filter 410B is to annotate activated carbon fiber filter 410D.

People can omit and annotate activated carbon fiber filter 410D unlikely among very sensitive other embodiment of the toxicity Fungicidal substance of trace therein.For example, in this case, spray filter 410F can be in order after catching filter 410B, as next filter.

In addition, in other environment, can not need spray filter 410F, and it is just enough only to catch filter 410B, adds sometimes in the time of necessary and annotate activated carbon fiber filter 410D.

Filter sequence and combination: four filters

Fig. 8 C and 8D show the 4th embodiment that filtration device structure wherein comprises four

filter

410B, 410D, 410F and 410FF successively.

In Fig. 8 C and 8D, the air-flow through filtration device structure at first runs into mainly catches filter 410B and annotates active carbon filter 410D.Next be exactly two spray filter 410F and 410FF.

In the present embodiment, when having two or more spray filter 410F and 410FF, all comprise a kind of different beneficial property released under each spray filter preferable case and penetrate material.

For example, the next filter 410F in the sequence can spray fragrance or fragrance in air, can spray the less antibacterial material of toxicity with last filter 410FF in the time series.

Therefore, in four filter embodiment of Fig. 8 C:

I) bacterium in the air-flow is filtered that device is caught and is killed by the hypertoxic antibacterial material on the first filter 410B;

Ii) poisonous antibacterial material is removed from air-flow through annotating active carbon filter 410D;

Iii) fragrance or the fragrance from penult spray filter 410F is evaporated in the air-flow; And

Iv) vaporific appropriate antibacterial material is injected in the air-flow through last spray filter 410F, so that the air-flow that from equipment, sprays comprises the non-toxicity antibacterial material of appropriateness.

Notice that be evaporated in the air-flow fully or basically through material, some materials are injected in the air-flow.By contrast, also having other materials is to be injected in the air-flow as molecule or liquid mist.For example, before example in, fragrance or fragrance are evaporated in the air-flow probably, are the forms that mist gets into air-flow and the appropriate antibacterial material of some types is ejected into what adopt probably in the air-flow.

Therefore; When having two or more spray filter 410F and 410FF; And has evaporated material and other have mist when producing material when one in these filters; Under the preferable case, air-flow at first runs into the filter 410F that has evaporated material, just runs into then to have the filter 410FF that mist produces material.

If because mist produces material on penult filter (410F among Fig. 8 A), then mist is hunted down probably or is collected on last filter (410FF), but not passes the entering surrounding environment, so we recommend this sequence and structure.

Be used to guarantee the filter sequence mechanism of acceptable filter sequence

In order to ensure the assembly in the filtration device structure with expectation series arrangement or be installed together, but each filter mounting all has and is merely able to the mechanism that meshes with predetermined receiving sequence and another filter mounting.Each of filter mounting 410C, 410E and 410G all has can guarantee that filter can only carry out interconnective catenation sequence device with above-mentioned sequence.

But the contour shape of the catenation sequence device on each filter frame all can only accurately mate with the respective profile on the next filter frame in any receiving sequence.In Fig. 7 B, what the catenation sequence device adopted is that bayonet type is installed.The yardstick that bayonet type on each of

frame

410C, 410E and 410G is installed and the design of position have all been guaranteed unacceptable combination not to take place, as stated.

For example, the embodiment of filtration device structure can not make and annotate activated carbon fiber filter 410D as first filter in the sequence.Therefore, in acceptable combination,

filter frame

410C, 410E and 410G are designed to have the connector that can only mate or be connected with another filter frame.

For example, in Fig. 7 B, can see acceptable combination, the rear portion of wherein main filter frame 410C can mate and be connected with the front portion of the frame 410D that is used to annotate active carbon filter.

In other embodiments, when having corresponding pin hole, the catenation sequence device adopts is the form of the pin on that filter frame that can only be complementary with another filter frame.The pin and the position assurance of pin hole to have only acceptable catenation sequence be feasible.

As stated, when each filter mounting interconnected with acceptable sequence, filter mounting combined and creates the impermeable barrier of bacterium.

Still as stated, filter mounting also is to be installed together with acceptable sequence, to form single lamination.

One or more secondary filter

In the embodiment of Figure 1A and 1B; Under

main filter assemblies

410A, 410B and 410C and preferable case, also have 410D～410G; Under the preferable case, one or more secondary filter that inlet device also comprises with main filter assemblies 410A～the 410E/G serial links to each other.

In the embodiment of Figure 1A, secondary filter 520B has partly reduced the amount of bacteria in the air-flow, but not all air-flow all passes secondary filter.For example, in an embodiment, when not existing rubber strip to seal the slot between cover 10 and the substrate 11, some air-flows can get in hand dryers 1 through these slots, and as a result of, allow bacterium through the slot entering.Here it is why in the present embodiment external filter 520B only be regarded as the reason of " secondary filter ".

Keep air-flow

Each of one or more secondary filter 520D all has bacterium and catches filter for installation (520B).Reason is that the filter that has more than has increased the whole combination of filter material " thickness " that bacterium must pass, and is filtered the probability that modulator material is caught thereby increased bacterium.

In the embodiment of Figure 1A and 1B, the air that gets into

frame

10 and 11 has finally arrived heating element heater 300 after having passed a series of holes.(because 520D demonstration in this hole has

secondary filter

520A, 520B and 520C in decomposition view, these three parts that show the secondary filter assembly are how to be installed among the 520D of this hole, and therefore initial secondary apertures 520D is blocked in Figure 1A)

The coarse mesh of

secondary filter support

520A and 520C is used to filter out bigger dust and other particles.Other embodiment can comprise more than three layers in the secondary filter assembly.

The secondary filter 520B that is positioned at this initial apertures 520D has stopped the bacteria particles of the inlet device of most entering hand dryers.But, in fact this secondary filter 520B does not catch all bacteria particles, and also has bacterium to get into hand dryer 1 through the slot in the

frame

10 and 11, even when cover 10 is opened.Therefore, being arranged in main filter 410B on the main aperture 405 is used to catch air-flow and escapes from any bacterium that initial secondary filter 520B catches.

According to logic, the thickness of the filter material that air-flow must pass is big more, and then the air-flow captive possibility of bacterium of carrying secretly is big more.But, the thickness that only increases the main filter 410B on the fan inside outer cover 400 is not a feasible solution.This is because the part of the operating parameter that specific air input of the action need of fan 401 or circulation are used as fan.If only thicken main filter 410B, then can cause the speed of air entering fan housing lower, this most probable causes the overheated and degeneration of fan mechanism, even can cause that fan motor catches fire.

Therefore, under the preferable case, not the thickness that adopts the simple main filter 410B of increasing, but have the filter of catching of two or more series connection, so that effectively increase the quantity of the filter material that air-flow must pass.In other words, make air-flow before arriving main filter 410B, must pass one or more secondary filter 520B exactly.

Under the optional situation, exist therein among a succession of embodiment that catches filter, these also can multiple

catch filter assemblies

410B and 410C realizes through increasing.This realizes through increasing the assembly lamination.In other words, the filter of catching with several series connection is better, rather than has the single filter of catching big and thickness equivalence.

In an embodiment, because air-flow is to pass each filter successively one by one, so secondary filter 520B also can be counted as with main filter 410B and is in series.

Knowledge as a setting, fan component 401 is as air is drawn into the air pump the pump from

frame

10 and 11 inside.For the airflow rate that keeps producing, but must there be enough air capacity air feed fans to suck by fan 401.This is the reason why

frame

10 and 11 has sizable inside, so that the air of quite big volume can be positioned near the fan component.This also be why include enough air with the frame that satisfies the suction of fan 401 assemblies aspect the time per unit air capacity and require in, just initially secondary apertures 520D and

filter assemblies

520A, 520B and 520C separate the reason of enough large spaces for next nearest inlet in main aperture 405 and

main filter assemblies

410A, 410B and 410C and the sequence.

The benefit of a series of filters

In the present embodiment, at least one secondary inlet 520D can be positioned on the outer surface of frame 10, so that can be approaching from the outside user of frame.Figure 1A shows

assembly

520A, 520B and the 520C of secondary filter with decomposition view, represent its assembly can carry out from the outside of frame 10 near and change.

In the embodiment of Figure 1A with inner main filter 410B and external secondary filter 520B and 1B, external filter 520B catches most of dust and bulky grain.This is mainly used in the internal ramp 410B of winner and catches bacteria particles.

Find that in experiment test if having only secondary filter 520B, then hand dryer 1 can reduce 79% bacteria particles from the air-flow of hand dryer ejection.Believe that this loss in efficiency is because some bacteriums have got into

frame

10 and 11 through the tiny slot between the edge of cover 10 and substrate 11.

But, experiment test demonstrates, and through main filter 410B and secondary filter 520B on last inlet 405 that combines to be positioned at the fan frame, hand dryer 1 can be realized the target of 100% removal bacteria particles from the air-flow 200C that is sprayed.

On the surface of cover 10 and wherein this is that those of unique filtration device structure are revised among the embodiment to main therein filter bits; Under the preferable case; When using, sealing slot or the inlet of every other entering frame, can realize that preferred 100% bacterium reduces.For example, the slot between frame 10 and the substrate 11 can be installed rubber washer, seals when closing with pressed towards substrate 11 with convenient cover 10.But, when cover be opened when making the bacterium access arrangement this modification weak effect some.In other words, in the present embodiment, all that in the frame is not to have a mind in when design all be sealed to the level that prevents that bacterium from getting into as the slot of the air flow path of equipment.

For avoidance of doubt, the air flow path of having a mind to design of equipment can be recognized through those holes that is used to let air communication cross of having a mind to provide, and not comprise that air can the non-non-slot of having a mind to that gets into wittingly.

In other embodiments,

secondary filter support

520A and 520C can also hold the material that a stacked package contains fragrance.In other embodiments, secondary filter not only can be carried the fragrance carrier, and can carry the filter material that is marked with the antibiotic and sterilizing material.

Filter is changed

In the present embodiment, filter actual acquisition bacteria particles with kill captive particle.As a result, after a period of time, filter can be blocked by dead bacteria particles.Therefore, in the embodiment of Figure 1A, suggestion filter or filter 410B and 520B changed in every month.

In actual use, be responsible for personnel that hand dryer safeguards and may forget that the desired that kind of optimum operation condition changes filter continually.If filter is not replaced so that blocks, then may damage motor.For example, because the filter that blocks allows the less air entering need prevent overheated motor, so motor maybe be overheated.

Therefore, in the modification embodiment of Fig. 6 A and 6B, bacterium catches filter for installation and comprises filter replacing mechanism, the filter material that the automatic replacing of this mechanism enough replacement filter material of ability is being used.

In the embodiment of Fig. 6 A, filter replacing mechanism comprises spool motor 700.In Fig. 6 A, what filter material adopted is the form of the volume of sheet filter material 440B, advances around spool 710 with the mode that is similar to conveyer belt.

Sheet filter material 440B crosses the secondary apertures (not shown) of the cover 10 of Fig. 6 A, so that be used as the filter of this secondary apertures.Therefore, after a period of time, 440B passes the hole along with filter material, and then after a period of time, the filter material that is using periodically is replaced the filter material replacement.

In other embodiments, sheet filter material 440B is applicable in the main filter assemblies.

The motion of spool motor 700 is to be controlled by the sequential of control spool motor and the microprocessor control unit of running.Motor 700 can be continuously or moving filter modulator material 440B discontinuously.For example, motor can every month moving filter modulator material once so that changed the filter material that is used for coverage hole in every month effectively.Under the optional situation, motor 700 can come progressive moving filter modulator material 440B with the constant very slow-speed of revolution.This can make more filter material participate in filtration treatment.Suppose that this filter material 440B often changes, as every month once, mean that then the possibility that filter that this circulation form uses gets clogged is littler.

Present embodiment has guarantees that filter material is by tight guiding of filling in the hole.

Fig. 6 B shows another kind of distortion, and wherein sheet filter material 440B forwards the next one to and finally breaks away from first spool 710A from a spool as cinestrip, and air can not get into

frame

10 and 11 with being filtered on it.This means that the user who is responsible for maintenance must change filter on time before filter fully forwards the second spool 710B to.But, the advantage of this distortion is that filter unlikely is blocked to the degree that causes fan motor 430 impaired and overheated.

To notice that the schematic illustrations of Fig. 6 A and 6B only shows the details that filter is changed machine-processed embodiment, and in order simplifying, from Fig. 6 A and 6B, to be omitted such as other interior details of hand dryers such as fan housing.

Security feature

In the embodiment of Figure 1A, inside master's

filter assemblies

410A, 410B and the 410C of Figure 1B and Fig. 3 can only change with the intraware that exposes in the frame through opening frame.

For the hand dryer of this technology, generally speaking, the step of being opened the frame of hand dryer by the user who is not trained into the electrician may increase the risk that the user gets an electric shock.

In the embodiment of Figure 1A, hand dryer 1 has electric control circuit, is used for to hand dryer 1 supply electric power.Electric control circuit has the mechanism cut off, and is used for the supply of when opening frame, cutting off the electricity supply, the risk of when opening frame, getting an electric shock with minimize user.

In Figure 1B, what the mechanism of cut-out adopted is the form that elasticity is installed switch 501, only when being pressed, starts the power supply supply.

Fig. 2 A shows the embodiment that its cover 10 is in the present embodiment of closed condition, and Fig. 2 B shows the situation that cover 10 is in open mode.In the open mode of Fig. 2 B, the user can be near intraware, and particularly can change inner main filter 410B.

In order to remove the risk that the user gets an electric shock, the inside of cover 10 has the cut-out mechanism activator appliance or the actuator of upright mark post 502 this forms.Through comparison diagram 2A and 2B, obvious when closing cover, the most advanced and sophisticated push switch 501 of mark post 502.And when cover was opened, the tip of mark post 502 was risen to leave and is closed 501, thereby not to hand dryer 1 supply electric power.

Switch 501 is positioned at and is installed on the substrate 11.The cover 10 of frame removably is connected to substrate 11.Mark post 502 is installed on the inner surface of cover.

In optional embodiment, pressing device (mark post) can be installed on the substrate, and switch can be installed on the inner surface of cover.

The characteristic of cutting off mechanism helps, and helps at least in part, realizes that it is the target of 100% aseptic heating air flow that the dried hand equipment of sterilization is emitted under the preferable case.This is because it allows the user to change internal ramp 410B, when being exposed to intraware, does not have the risk of electric shock simultaneously.Therefore, it provides the safer environment that can put into a series of filters at hand dryer.

The installation of hand dryer

In the embodiment of Figure 1A, for example, substrate 11 is fixed on the wall.Through frame 10 is connected to substrate 11, hand dryer 1 can be installed on the wall.This means that in fact, if hand dryer 1 is defective, then the user can take off cover 10 from substrate 11, and connects flawless replacement cover 10.

Electric change-over switch 501 means when the user opens cover 10, installs or removes cover and its included component parts, has increased level of security.Cut off switch 501 and guaranteed that equipment 1 can not become electricity is arranged, till having closed cover.The commercial value of this characteristic is that therefore hand dryer 1 can be safeguarded by the personnel that are not titular electrician.In general, this has practiced thrift the cost of safeguarding these dried hand equipment, and the off-position when hand dryer is opened makes and not need to use this equipment also to have sizable cost savings in the country that titular electrician installs.

In addition, in building, can carry out the initial installation of substrate,, can cover 10 and appended assembly thereof be enclosed such as 400 and 430 together after other people then so that circuit is connected to main power source by the electrician such as heavy constructions such as hotel or hospitals.

Can do not need be the skilled worker to come on the spot another advantage that the assembling and the substrate of cover 10 were opened in 11 minutes and repair hand dryer 1, and the user just can simply remove cover assembly 10 and parts thereof, and change with new cover.Then, the defective cover repairing of just can taking away.This means that the mechanic need be in the time of the place overspending that hand dryer is mounted.In addition, also practiced thrift user's time, and the user can change cover and parts thereof under situation about not wanting help.

In the embodiment of Figure 1A and 1B, hand dryer 1 is connected to external power source through terminal block 500.Terminal block helps the electric control circuit of hand dryer 1 is connected to outside main power source.

In Figure 1B, the electric control circuit of hand dryer 1 has plug 503, and it can arrive terminal block 500 by connector, to be connected to main power source.

In Figure 1A and 1B, hand dryer 1 has the sensing device of detector sensor 600 forms.

Detector sensor 600 detect hands whether appear at cover 10 the front protruding terminus opening 14 near.When detection was in one's hands, detector sensor 600 activated rotary fans 401 and heating element heaters 300.Therefore, when the user with hand be put into end openings 14 below the time, hand dryer 1 activates and begins to dry user's hand automatically.

In the present embodiment, detector sensor 600 comprises infrared sensor.

Ambient atmosphere is carried out sterilization

Recall, the hand dryer 1 of Fig. 1 has gets rid of the airborne bacteria particles that is inhaled in

frame

10 and 11 and fully or be close under the situation of removing bacteria particles fully the ability with its discharge.Therefore, if periodically activate fan 401, the modification embodiment of then this hand dryer 1 can play the effect of atmosphere removal of bacteria equipment.For example, if the hand dryer of present embodiment 1 every at a distance from 30 minutes or 1 hour perhaps other proper spacing be activated, then can be regularly the air in the communal bathroom be for example got rid of most bacteriums that air is carried secretly.

In order to realize this goal, the equipment 1 of modification has timer control circuit, is used for fan 401 is regularly activated predetermined amount of time automatically.

Therefore, the cycle of equipment 1 is activated effectively automatically the part atmosphere around the dried hand equipment is carried out sterilization.For example, timer control circuit can activate 3 minutes at a distance from half an hour.

In this modification embodiment, detector sensor 600 can also detect and not have hand.When near detector sensor 600 detects endways opening 14, not having hand, can activate hand dryer 1 automatically and make it to operate, simultaneously heated air flow with air purification mode.This has guaranteed that hand dryer 1 can not blow to cold or not hot air and has placed below the end openings 14 on hand.Therefore, timer control circuit can be with clocklike interval or activated equipment 1 discontinuously, so that equipment 1 ambient air is carried out sterilization.

In 1 year, exist in the season of higher air borne disease incident, hand dryer is had surrounding air is carried out this characteristic of additional functionality of sterilization particularly useful.For example, particularly useful between the influenza seasonal period.

When in filter mounting, also having aroma materials, this characteristic also makes hand dryer play the effect of air freshener.For example, between filter mounting 410A, 410C, 520A and 520C, can comprise fragrance or fragrance matter liner.When combining timer control circuit to use, this means that the surrounding air in washroom or the communal bathroom environment can be clocklike automatically and periodically to inject fragrance at interval.

When use equipment 1 is used as adding the device in the surrounding air to the ambient air sterilization and/or with fragrance, do not activate heating element heater 300 under the preferable case, otherwise for example the temperature of toilet will unnecessarily increase or reach the uncomfortable level of user.

Alternatively, in certain embodiments, between this automatic active period, still can activate heating element heater 300 through timer control circuit.We find that heater is operated can the superheated ambient air.

Therefore, some embodiments of the present invention can play the effect of air sweet smelling generating device, aseptic hand dryer and surrounding air degerming device simultaneously.

In another embodiment; Timer control circuit has light sensation device 504, and can selectively limit, so that only have surround lighting when the light sensation device shows; The just automatic activated equipment of timer control circuit is used for ambient air is carried out sterilization and perfuming.In other words, for example in the time of washroom or the complete dark in toilet, this function can not activate automatically.This can be applied to wherein, and the washroom diurnally uses and does not need equipment in continuous situation about turning round at night.

Chemoreleaser

In other embodiment of the embodiment of hand dryer 1 and said flow equipment, air-flow can be a discontinuity.In other words, can have for a long time not through this equipment generation working air current.

With reference to figure 8A and 8C, and the exemplary embodiment of Figure 10 B, 10C, 11B, 12C, 12D etc.These have one or the embodiment of more a plurality of release filter 410F, 410FF in, on filter fiber, have and can become airborne active material.For example, in this embodiment, active material can be spices, perfume or even the nontoxic antibacterial material of appropriateness.

Activate in the composition at air-flow, active material effectively can become air borne in a period of time at least.For example, active material can be evaporated to steam, perhaps is diffused in the air as mist.

In repairing the embodiment that ends, active material can become airborne releasing agent with restricted activity material at normal temperatures and pressures and combine, but, when said composition is exposed in the air-flow, releasing agent with release of active ingredients in air-flow.

An advantage using active material and combine with this releasing agent is that when not having air communication to cross equipment, it has avoided or minimized the passive diffusion of active material in atmosphere.Therefore, with even without working air current the time, active material also will continue and little by little be diffused into airborne situation and compare, maybe last much longer at the active material that on said filter, exists.

Active material can be the combination that can become airborne any material or material to the object of the invention.For example, active material can be fragrance, eliminating smell agent or biocide.Biocide can be bactericide or pesticide.Under the preferable case; Activating agent is the biocide such as the positive alkyl dimethyl benzene of saccharic acid ammonium, quaternary ammonium salt (for example, chloride), triclosan, neighbour-benzyl chlorophenol (o-benzyl chlorophenol), 2-phenylphenol and/or N-alkyl N-ethylmorpholine base sulfate.

Under the preferable case, active material is volatilizable in the normal range (NR) of environment and pressure around, but this is unimportant for the purpose of the present invention, as long as active material can keep the air borne of enough time so that bring into play its effectiveness.

Active material can be dissolved or suspended in the carrier.In case after being released to surrounding environment, this carrier can pass through preparation to improve the volatility of active material.Carrier can be by preparation so that stabilizing actives physically and/or chemically, degenerate along with the time preventing.For example, carrier can comprise the UV stabilizing agent, is used for reducing the degeneration of active material when active material when being exposed to sunlight at transportation or memory period.

Carrier can be at room temperature to volatilize and preferably nontoxic to animal solvent, such as water, linseed oil, appropriate organic solvent, ethanol or its mixture.It is favourable using solvent mixture, for example, and when active material comprises two kinds or have different dissolubilities or during the material of dilution attribute.Under the preferable case, when active material and/or carrier comprised volatile ingredient, releasing agent was with coating active material and/or carrier.

Releasing agent comprises following any material or combinations of substances:

(1) can contain or postpone active material becomes air borne, for example volatilization; And

(2) at normal temperatures and pressures, in still air, keep stable.

Therefore, the prescription of releasing agent and/or preparation change according to the active matter qualitative attribution that is used for application-specific.Therefore, releasing agent can be compatible with active material, and can use the different formulations of releasing agent according to active material.Active material can be injected into, embeds or wrap up, and perhaps physically or chemically is tied to active material.Under certain preferred prescription situation according to the present invention, activating agent is included in the volatility biocide that forms microencapsulation in the releasing agent.Under another preferred form, active material is a fragrance.

Releasing agent can be under room temperature and normal pressure, to have very low or almost do not have volatile solvent, gel, lotion or slurry, and this solvent, lotion or gel are only through applying the volatilization of air-flow and/or warm air.For example, active material can stably be injected, be dissolved or mixed in releasing agent under room temperature and pressure, and active material is to be close to anti-volatilization at least, and sneaks into releasing agent under the preferable case.In case be exposed in the moving air, under the optional situation through the heating, then releasing agent will become volatile and/or unsettled, thereby active material is discharged in the air-flow of process.

When releasing agent comprises solvent, it under room temperature and normal pressure can be thickness with non-volatile.Suitable examples of solvents comprises the vegetable oil with heavy distillat, and for example culinary art is oily, lanolin, and aliphatic acid, for example stearic acid.

When releasing agent comprised gel, it can be a polymeric material.Polymeric material can be homopolymers or copolymer.Polymeric material can be crosslinked.

Under the preferable case, releasing agent is the form with Caplet or microencapsulation.The general diameter of microencapsulation is less than 500 μ m, and is under the preferable case in the scope of 5-200 μ m.The preferred especially form of capsule is to have wall or the shell mould capsule that is generally spherical hollow material shell, and the material of shell is insoluble to active material.Material is generally plastic material.Plastic material can be polymer or copolymer, is crosslinked under the optional situation, and comprises the known appropriate addn that can obtain the expectation attribute under the optional situation.Plastic material can be a resin.Plastic material can be an amino resins, such as condensation product of urea-melamine-formaldehyde etc.

There is the whole bag of tricks to make this shell capsule, comprises being used at present through utilizing urea-formaldehyde or carbamide polymer to produce the in-situ polycondensation method of amino resin capsule.This process can relate to dispersion or the emulsion that forms active material, for example under the stirring condition, in the aqueous solution of urea-formaldehyde or melamine-formaldehyde pre-condensate, is used to obtain the capsule of preselected size range.Through acidic catalyst can regularization condition causing the condensation of precondensate, the result obtains being separated with solution and surrounds the condensation product of the active material of dispersion, thereby produces microencapsulation.

Because capsule prevents evaporation or other losses of active material, so microencapsulation shows excellent active material and keeps performance for a long time, only if thereby the integrality of capsule wall is damaged and discharges active material, and perhaps wall breaks.Under its many preferred forms, the present invention pays close attention to has good stable storage attribute but its polymer wall loses the microencapsulation of enough structural intergrities easily when being exposed to quick flow air in still air.

Form by coacervation process under the optional situation of microencapsulation; Wherein the carrier with the oil sac form is surrounded by very thin polymer thin film; This film generally is unsettled from mechanical aspects; But its hydrophobic and wet environment had resistance, this wet environment for example just exists in the public lavatory.This attribute can be used to the active material transmission, wherein transmits by mechanical force and initiates, and for example disturbs the integrality of polymer thin film through air-flow, and discharges active material.

Wherein releasing agent comprises lotion or slurry, and they can include adhesive synthetic or nature, and for example gum arabic or synthetic polymer binder are to play the effect of bond.

Releasing agent can be the micropore capsule product.Releasing agent can be the melamine polymers shell.Under the melamine polymers shell preferable case by being used to keep the microencapsulation of activating agent to form.Polymer shell can seal, and therefore can be effective to keep the volatility activating agent, such as fragrance or biocide.Can comprise fragrance and biocide simultaneously in the microencapsulation.Fragrance can be chemical reaction not to take place, therefore storage and can not worsening in same capsule.Under the optional situation, some microencapsulations can comprise fragrance, and other microencapsulations can comprise biocide etc.The mixture of microencapsulation can be stored in such as in the same devices such as filter cylinder.Microencapsulation can change dimensionally, such as in the scope of 3-500 μ m, changing, under the preferable case between 3-200 μ m, and under the more preferred situation, between 5-100 μ m.

Releasing agent can be by reasonable preparation, to be used for combining or adhering in addition substrate.Substrate can be the porous flat plate such as woven wire or plastic wire.Dull and stereotyped can have enough specifications, so that allow air to flow through.Releasing agent can be viscous enough, so that adhere to dull and stereotyped surface and himself.

Substrate can be a filter media.Filter media can be a filter fiber.Filter medium can be natural or synthetic material, depends on to use and required filter attribute.Filter medium can comprise such as cotton fabric etc. based on cellulosic fiber, perhaps such as synthetic materials such as polyester, and perhaps their combination.Substrate can inject or be coated with such as other useful materials such as carbon in addition, so that play the effect of eliminating smell agent and/or absorbent.

Releasing agent and active material can be through spraying, whitewash or roll extrusion is applied to substrate, can be disposable or alternatively layering carry out.Because air-flow is applied on the substrate, so the superficial layer of composition exhausts, thereby prior unexposed surface is exposed to surrounding environment.The combination material can provide new surface through the long-time use of moving air.

Under the preferable case, active material is included in the releasing agent of the miniature capsule form of polymer, and microencapsulation can be sprayed or be applied in addition on the substrate surface such as filter, to be installed in the filter cylinder.Microencapsulation can apply through on substrate, spraying milk.Suitable microencapsulation system can obtain from Reed Pacific Pty Ltd, and its name of product is " Potenza ", uses suitable additive so that the air-flow releasability to be provided under the optional situation.

Synthetic may reside in the filter cylinder of sealing, and this filter cylinder is used to preserve composition and can be easy to replace the composition of using up.Filter cylinder can comprise the container of sealing, wherein holds the composition that will store.In case composition is passed to filter cylinder, filter cylinder is vacuum-packed under preferable case.Filter cylinder can be processed by any suitable material of the said composition components of tolerance.Suitable material can comprise APET, PETG, polypropylene and polyacrylonitrile, because they have the transparency, thermoplasticity and general chemical resistance.Other materials with less transparency can comprise polyethylene and nylon.Can be because of intensity and chemical resistance and select other materials, for example aluminium or stainless steel etc.Certainly, according to said composite formula, the skilled person can select suitable material or combination of materials.

Container can comprise sealer.Sealer can be activated so that give environment on every side with the content exposure of filter cylinder.Sealer can be bent, movably, or permeable.Activate to use when exposing its content when filter cylinder is positioned in, sealer can be suitable for being activated.Sealer can be a film.Film can be processed by metal forming or such as poly flexible plastic.

According to its applicable cases,, can composition be applied on the substrate of flat type of parallel distribution or series arrangement with respect to the expectation direction of use air-flow.Under the alternative situation, substrate can be the form of row, knot or amorphous fiber, thereby along with previous composition surface is exhausted gradually, the new surface of composition is exposed to surrounding air.

Many factors are depended in the variation of normal room temperature, humidity and pressure, comprise position and season.Usually, the characteristics of the high latitude position far away apart from the equator are colder temperature and lower air pressure, and the characteristics of equatorial zone are warm surrounding environment and higher humidity and pressure.The skilled person knows, when judging composite formula, need consider these factors.

Example 1
