Data can exchange in the appropriate case, so as to embodiments of the invention described herein can with except illustrating herein or
Order beyond those of description is implemented.
The invention provides a kind of screen window with purification function, screen window is made up of purification assembly, can prevent particle
Thing and harmful substance are got in from window, so as to be purified to the air got in from window, and then make room air
Quality improved.
Specifically, as depicted in figs. 1 and 2, purification assembly includes：Except knoisphere 1 and collection knoisphere 2, except knoisphere 1 leads to positive electricity, collection
Knoisphere 2 leads to negative electricity, so can except knoisphere 1 and collection knoisphere 2 between produce electrostatic field, when thering is air to pass through, dedusting
The electric discharge of layer 1 makes the dust in air positively charged, because collection knoisphere 2 leads to negative electricity, therefore, it is possible to attract positively charged dust, makes
It is adsorbed on collection knoisphere 2.External communication electricity can be converted into direct current in actual use, and by positive pole with removing the electricity of knoisphere 1
Connection, negative pole is electrically connected with collection knoisphere 2.
By using such technical scheme, effectively air can be purified, so as to improve air quality.Together
When, except knoisphere 1 is in discharge process, air agitation can be made to form ion wind.And then the velocity of liquid assets of air is accelerated, enter one
Step increases ventilation.
Further, as shown in Fig. 2 purification assembly includes transformer 31 and/or voltage-stablizer 32；
Except knoisphere 1 and collection knoisphere 2 are connected with transformer 31, the power-on voltage of knoisphere 1 and collection knoisphere 2 is removed to reduce.
In actual use, the power-on voltage except knoisphere 1 and collection knoisphere 2 can be reduced to by below 36V by transformer 31, and then avoided
There is the generation of electric shock accidents.
More preferably, except knoisphere 1 and collection knoisphere 2 are connected with voltage-stablizer 32, to stabilization is except knoisphere 1 and collects the logical of knoisphere 2
Piezoelectric voltage.It can so make except knoisphere 1 and collect the power-on voltage that can keep stablizing of knoisphere 2, be protected dust removing effects
Card.
More preferably, except insulating element (not shown) is provided between knoisphere 1 and collection knoisphere 2, knoisphere 1 and dust will be removed
Layer 2 insulate.Can so avoid except knoisphere 1 and collect knoisphere 2 between directly turn on so that ensure that except knoisphere 1 and collection knoisphere 2 it
Between electrostatic field be stabilized, and then ensure that dust removing effects.
As a kind of embodiment, purification assembly also includes adsorption layer 4；Adsorption layer 4 is with removing knoisphere 1 and/or collection knoisphere 2
Connection, to adsorb the harmful substance in air.When except knoisphere 1 discharges when can produce ozone, substantial amounts of ozone can be made to human body
Into infringement, adsorption layer 4 can adsorb ozone while other harmful substances (such as formaldehyde) in air can also be adsorbed, further
Improve the clean-up effect of air.Wherein except knoisphere 1, collection knoisphere 2 and adsorption layer 3 can be arranged in order setting as shown in fig. 1.
Specifically, purification assembly also includes the first frame 5, and the first frame 5 is connected on window, except knoisphere 1, collection knoisphere 2
It is both connected to adsorption layer 4 on the first frame 5.It should be noted that purification assembly can include screen pack, screen pack can be connected
On the first frame 5, to winged insect, large particulate matter is filtered.
As shown in figure 3, except knoisphere 1 may include the second frame 11 and wire netting 12, the second frame 11 is connected to the first frame 5
On, wire netting 12 is connected on the second frame 11, and leads to positive electricity by the second frame 11.Wherein, the second frame 11 can be used
Metal material makes, but is not limited to this, it would however also be possible to employ other conductive materials, and wire netting 12 discharges after logical positive electricity, so that
Dust in air is positively charged.Wire netting 12 can be connected to the second frame 11 and the tungsten filament being arranged in order for two ends, so
Discharge effect can not only be ensured, and can also ensure that reduction to the resistance of ventilating air generation and then ensure except knoisphere 1 leads to
Air quantity, while can also prevent to filter bulky grain thing and winged insect etc..
As shown in figure 4, collection knoisphere 2 includes the 3rd frame 21 and collecting plate 22；3rd frame 21 is connected to the first frame 5
On, collecting plate 22 is movable to be connected on the 3rd frame 21, and leads to negative electricity by the 3rd frame 21.Wherein, the 3rd frame 21 can
To be made using metal material, but it is not limited to this, it would however also be possible to employ other conductive materials, collecting plate 22 is right after logical negative electricity
Positively charged dust produces electrostatic attraction in air, and then makes the dust adsorption of positive charge to collecting plate 22.Now insulate
Part can be arranged between the second frame 11 and the 3rd frame 21.
Further, as shown in figure 5, collecting plate 22 includes setting mounting hole 211, rotating shaft on rotating shaft 221, the 3rd frame 21
