Description
Technical field
The invention belongs to air cleaning unit technical field, more particularly to a kind of portable air using physical absorption
Purification techniques.
Background technology
Since economic extensive style is fast-developing, the air quality in people's life deteriorates serious, to frequently occur haze cause
Severely exceed PM2.5 fine particles etc. in air, formaldehyde and volatile organic matter in the interior decoration such as existing building and automobile
Pollution index is seriously even more customary beyond health standards.In order to mitigate this threat and injury, it is net that people seek help from air
Change this kind of technique device for crossing air filtering of device.At present, in the market cost is low and will not cause the air purifier master of secondary pollution
If physisorption type, they realize air filtration using conventional porosity filter material mostly, such as non-woven fabrics, filter paper, gather
Compound fiber, foam, activated carbon, HEPA filter membranes etc..To be difficult to what is taken into account since there is both filtering efficiency and air permeability
Technology barrier, in the market are common often larger come the air purifier that makes, volume using porosity filter material, it is also desirable to utilize
The fan or wind turbine of relatively high power drives air to flow through filter element.Therefore, this kind of air purifier is in the portability used
On have very much limitation.
The content of the invention
The present invention overcomes deficiency of the prior art, there is provided a kind of subminiature air cleaner, not only can be empty with high-efficient purification
Gas, moreover it is possible to be convenient for carrying, compact practicality.
The technical scheme is that：A kind of subminiature air cleaner, including filter layer 7, mini-fan 10 with it is chargeable

Porous woven cloth that is standby, selecting during preparation mesh geometric scale no more than 500 microns and be evenly distributed, passes through triboelectrification method
And/or prepared 14 thin layer of carbon fiber stratum reticulare is fit together by way of close pressure or dot matrix pressure, multilayer can be superimposed as, with
To reach in thickness 1 millimeter and more than.The electrostatic fibre, its material type can be metallic fiber, carbon black series fiber, lead
Electric type metal compound fibres and conducting polymer fiber type or electret fiber, it is preferred to use surface is easily processed in more
The conductive polymer fibers in hole, such as polyester fiber, polypropylene fibre；The diameter of preferable electrostatic fibre is not more than 500 microns.
In the present invention, the intermediate adhesion layer, which is played, combines above-mentioned carbon fiber stratum reticulare 14 with above-mentioned electrostatic fibre stratum reticulare 15
Effect together.In one embodiment, intermediate adhesion layer 16 is formed using curable viscous polymeric component, such as ring
Oxygen tree fat, dimethyl silicone polymer (PDMS) etc..In the preparation, the sticky polymers that starting is in a liquid state are cast in previously prepared
Micro-pillar array on, microtrabeculae therein is evenly distributed, the pillar length of use be no more than 0.5 millimeter, its diameter range can be 50
Change between -500 microns of micron；Demoulded when sticky polymers are in semi-cured state or turn to cover, can obtained in this layer of viscosity
Polymeric layer longitudinally in there is the intermediate adhesion layer 16 of micro-channel array, micro-channel therein is a length of be no more than 0.5 millimeter, it is straight
Footpath is also between 50 microns -500 microns, and be evenly distributed.By the intermediate adhesion layer with micro-channel array of above-mentioned preparation
16, it is clipped between the carbon fiber stratum reticulare 14 of above-mentioned preparation and electrostatic fibre stratum reticulare 15, is bonded, mistake of the present invention is prepared
Filtering layer 8.
The filter layer 7 of above-mentioned preparation, air filtration passage therein possess from submillimeter, micron, nanoscale different scale,
And from the side of layer to internal layer again to opposite side, by the aspect of various networks in gradient, in very limited lamella body
Adsorption surface area is greatly increased in product.As the air flows past, on the one hand larger submillimeter, micro-meter scale duct and add
The suction-operated of upper electrostatic fibre, can stop most of particulate matters in air, on the other hand such as PM2.5 fine graineds, formaldehyde
Deng volatile contaminant gas then by activated carbon fiber outside and its porous interior surfaces absorption, so as in this limited lamella volume
Filter layer 7 in, realize superpower flowing through property absorption.
In the present invention, the filter layer 7 of above-mentioned preparation, can be fixed in outter frame shelf, with it is easy to use when be inserted directly into shell
In the slot opened up inside body 1.
