Detailed description of the invention
Below in conjunction with embodiment, the present invention is described further.The explanation of following embodiment is only intended to help and understands the present invention. It should be pointed out that, for those skilled in the art, under the premise without departing from the principles of the invention, it is also possible to right The present invention carries out some improvement and modification, and these improve and modify in the protection domain also falling into the claims in the present invention.
As shown in Figure 1 to Figure 2, the air purifier of the embodiment of the present invention, by depurator shell 1, air inlet fan 2, filter screen 3, Water fog generator 4, electrostatic equipment 5 and sewage receiver 6 form.
Described filter screen 3 is made up of front drainage screen 31 and rear drainage screen 32, and front drainage screen 31, rear drainage screen 32 are arranged on depurator Shell 1 is internal, and forms a closed cavity 7 with it.Filter screen 3 is used for filtering the foreign bodies such as large scale dust granules or hair, Closed cavity 7 with depurator shell 1 composition can assemble certain density water smoke simultaneously.
Described air inlet fan 3 may be installed air inlet, it is possible to is arranged on air outlet, is used for increasing air mass flow.
Described water fog generator 4 is made up of water fog generator 41, circuit module 42 and water storage case 43.Described water fog generator 41 use ultrasonic water mist generator, are used for producing water fog particle, and its principle is to utilize ultrasonic water mist generator to be impacted by water droplet Become the water fog particle that diameter is the least, then utilize the method such as fan or free diffusing to make water smoke be full of cavity 7.Water smoke concentration Can realize by controlling the power of supersonic generator.Circuit module 42 provides high-frequency signal source for supersonic generator 41.
Described electrostatic equipment 5 is used for making water fog particle electrically charged, by electrostatic generator 51, cathode metal net 52 and negative electrode 53 Composition.Electrostatic equipment 5 should be noted the insulation between positive pole and negative pole when implementing.Described electrostatic generator 51 uses small power DC Power supply electrostatic generator.Described cathode metal net 52 connects electrostatic generator 51 positive pole ground connection, and described negative electrode 53 connects electrostatic Generator 51 negative pole, described negative electrode 53 uses plane reticular electrode shape.High concentration charged water spray it is full of in cavity 7, The various sizes minute dusts in air can be flowed through by active adsorption.Granule after absorption is moved to anelectrode in electric field force effect, And be collected.The sewage collected is collected in sewage receiver 6 by the guiding gutter below anelectrode.
Described sewage receiver 6 is positioned at below anelectrode, is placed side by side on bottom cavity 7 with described water storage case 43.For convenience of dirty Water cleaning and replacing, sewage receiver 6 and water storage case 43 all can conveniently take out.
Operation principle of the present invention is as follows:
In use, air inlet fan 2 accelerates air flowing, increases air and enters the flow of air purifier.Front drainage screen 31 and rear drainage screen 32 cross large scale dust granules in air filtering, such as hair, bulky grain dust, pollen particles, plant seed Deng.Minute dusts granule in air, such as PM2.5 etc., need to use charged water spray absorption to purify.Water fog generator 41 produce water smoke, are full of cavity 7.In cavity 7, water smoke concentration is adjusted by controlling water fog generator 41 power.Electrostatic is sent out Raw device 51 adds electrostatic potential between cathode metal net 52 and negative electrode 53, wherein cathode metal net 52 ground connection, negative electrode 53 For negative voltage.Water fog particle is electronegative by principles such as sensing, exchange charges when negative electrode 53 so that it is have actively absorption The ability of minute dusts in air.Electrostatic potential can be regulated by regulation electrostatic generator 51 input direct voltage.Electrostatic potential number In value basis for selecting environment dust concentration, cavity 7 depending on water smoke concentration.Charged water spray around negative electrode 53 is in electric field force effect Under gather on cathode metal net 52, finally collect in sewage receiver 6.
This air purifier by forming the charged water spray of high concentration in confined space, actively absorption flow through in air various micro- Small size dust granules.Water smoke concentration, carrying capacity can be automatically adjusted according to practical situation, to adapt to air quality and the people of various places Living habit.Owing to using charged water spray absorption dedusting, the water fog particle of adsorption of dust is collected in sewage receiver 6, Therefore need frequently to change without easily-consumed products, reduce use cost, be also convenient for family and use.This air purifier is owing to adopting simultaneously With water smoke as working media so that dry air increases humidity after water smoke, it may have the effect of humidifier.
