Specific embodiment
The present invention will be further explained below with reference to the attached drawings and specific examples, so that those skilled in the art can be with
It more fully understands the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention.
Shown in referring to Fig.1, an embodiment of air purifier of the invention, including air purifier body 1, the air
Clarifier ontology 1 includes the air inlet 2 set gradually along gas flow direction, blower 3, filter screen group 4 and air outlet 5；It is described
Data collector 6 and data pick-up group 7 are provided at air inlet 2；The filter screen group 4 includes that a filter screen frame 41 and setting exist
Multiple strainers in filter screen frame, filter screen frame inner sidewall are provided with multiple track grooves 411, and the strainer slides in track groove, institute
It states strainer and is connected with the driving device 8 with controller, the driving device 8 can drive single strainer to be inserted into or extract out institute
State filter screen frame 41.
Existing aerial major pollutants are as follows: the toxic gases such as peculiar smell, formaldehyde, benzene in bulky grain dust, air,
PM2.5 and bacterium are arranged six layers of strainer according to existing these types of pollutant in opening of sieve, are respectively: primary filter screen 42 takes off
Smelly strainer 43, active carbon filter screen 44, HEPA strainer 45, nano-silver ionic strainer 46, dehumidifying strainer 47, for each pollutant
Corresponding purification strainer is set, and the moisture of humid area can be removed being finally provided with dehumidifying strainer 47.
The primary filter screen 42 is mainly used for the bulky grain dust particle of 5 μm of filtering or more, can effectively filter out in life
Scurf, hair can play the role of protection to internal other functional strainers, prevent bulky grain Particles Blocking internal screen,
So often accumulating a large amount of dusts and hair in primary filter screen 42, need periodically to replace primary filter screen 42 or clean, institute
It is arranged with primary filter screen 42 in outermost, it is easy to disassemble while protection to its internal screen.The primary filter screen 42 is metal
Strainer or non-woven fabrics strainer use non-woven fabrics strainer, non-woven fabrics strainer light weight, Quick-detachable cleaning, resistance in the present embodiment
Power is low and dust containing capacity is big.
The deodorization strainer 43 is by one of or several in nano-titanium dioxide, diatomite, attapulgite clay powder
Deodorization substrate be made, the deodorization strainer 43 can remove cigarette smoke, lavatory peculiar smell, house refuse peculiar smell, peculiar smell of pet.
The active carbon filter screen 44 has been widely used in benzene class, phenols, the esters such as processing containing toluene, dimethylbenzene, benzene
In the organic gas such as class, alcohols, aldehydes, to exhaust gas carry out Adsorption Concentration, after purification can direct emission, the active carbon filter screen 44
It is made of cocoanut active charcoal, the active carbon filter screen 44 uses the honeycomb of through-hole structure for carrier, with conventional carbon filter screen
It compares, there is more excellent aerodynamics performance, bulk density is small, and large specific surface area, adsorption efficiency are high, and air resistance coefficient is small,
Its phosphorus content has better clean-up effect in 35%-50% or so.
The characteristics of HEPA strainer 45 reaches 99.7%, HEPA strainer 45 for the effective percentage of 0.1 micron and 0.3 micron
It is that air can pass through, but tiny particle can not pass through, lung can be entered by being mainly used for filtering out the PM2.5 in air, haze etc.
Particulate matter.
Extensive utilization is to antibiotic and sterilizing field now for the nano-silver ionic strainer 46, and without any drug resistance；By force
Effect sterilization, can kill a variety of germs being harmful to the human body in several minutes；Permeability is strong, can be rapidly permeated by pore and subcutaneously be killed
Bacterium has good bactericidal effect to common bacteria, stubborn bacteria, drug-resistant bacteria and fungus-caused infection.
The dehumidifying strainer 47 is the ability that spunlace non-woven cloth has high-hygroscopicity and quick moisture absorption, can play dehumidifying
The dehumidifying strainer 47 is placed on the outer layer of filter screen frame, is conveniently replaceable by effect.
Specifically, as shown in Fig. 2, in above-mentioned air purifier strainer automatic switching method the following steps are included:
(a) data collector obtains air quality data: data collector setting is in air inlet, air purifier fortune
Row, while air enters from air inlet, data collector obtains the air quality data in air.
(b) air quality data that data collector will acquire is passed in data pick-up group, and data pick-up group will
The data of acquisition carry out constituent analysis, obtain the ingredient and content of pollutants in air, content, peculiar smell including bulky grain dust
Index, formaldehyde, the content of benzene toxic gas, PM2.5 content, the content of the bacterial content of unit area and moisture in air.
(c) strainer for the pollutant driving corresponding function that controller is analyzed according to data pick-up is inserted into filter screen frame
In carry out purification work.
Such as: obtained after data pick-up group analysis major pollutants in air be bulky grain dust more than 5um,
Formaldehyde toxic gas, PM2.5 particle at this time pass to obtained data in the driving device 8 with controller, controller control
Primary filter screen 42, active carbon filter screen 44 and HEPA strainer 45 are inserted into filter screen frame 41 and carry out purification work by driving device,
It is outer without work that its strainer is placed on filter screen frame 41；With the continuous purification of air purifier, data pick-up group 7 is detected
The bulky grain dust and PM2.5 particle of 5um in air is all purified, without containing the bulky grain for being more than 5um in air
Dust and PM2.5 particle, at this moment driving device 8 drives primary filter screen 42 and HEPA strainer 45 to extract the filter screen frame out, if this
When by detecting that the bacterial content of unit area in air is exceeded, at this time control driving device nano-silver ionic strainer 46 is inserted into
Into filter screen frame 41, method, ceaselessly monitors air quality data according to this, ceaselessly online replacement strainer in real time.
Embodiment described above is only to absolutely prove preferred embodiment that is of the invention and being lifted, protection model of the invention
It encloses without being limited thereto.Those skilled in the art's made equivalent substitute or transformation on the basis of the present invention, in the present invention
Protection scope within.Protection scope of the present invention is subject to claims.
