Fig. 2 be in Fig. 1 A-A to sectional view；
Fig. 3 is the structural representation of metal wire in the present invention；
Fig. 4 is the schematic diagram of low temperature plasma air cleaning unit in the present invention.
In the accompanying drawings：1 is mounting bracket, and 2 be emitter stage, and 3 be receiving pole, and A is represented between the level between wire between twisted point
Away from B represents the pitch of wire, and arrow represents the flow direction of ion wind.
Embodiment
Referring to attached Fig. 1 and 2, the invention provides a kind of low temperature plasma air cleaning member, including installation is arranged on
Emitter stage 2 and receiving pole 3 and supporting control circuit on support 1, it is important to：The emitter stage 2 include it is parallel and be symmetrical arranged,
Truncation surface is polygonal two metal tubes, and the receiving pole 3 includes on the middle vertical plane of two metal tube hubs and and metal
The parallel wire of pipe.
When specific design is implemented, the preferred regular polygon of truncation surface of the metal tube of emitter stage 2, and two metal tubes most connect
The angle in relative two face of the middle vertical plane of nearly two metal tube hubs is preferably 10 ° -170 ° and angle opening direction court
It is air inlet to the outside of mounting bracket 1.Between two metal tubes gear drive can also be set to make it have synchronous phase
To rotary freedom, in order to adjustment angle.Setting above is to form air cleaning passage to carry out guiding to ion wind,
Ensure air purification effect.The gear drive of setting can realize the relative rotation between two metal tubes, it should be apparent that,
Those skilled in the art can also realize rotating against for two metal tubes using the transmission mechanism such as belt transmission.
Emitter stage 2 and receiving pole 3 are applied in voltage under control circuit function, form ion field under high pressure effect, and
Trigger ion wind by discharging.And truncation surface is polygonal metal tube ion wind is played in guide effect, receiving pole 3
The sector space that wire or metal wire are formed with two faces in emitter stage 2 in 10 ° of -170 ° of angles forms whole air cleaning
Effective air oasis of unit.When bacterium in air and virus are by effective air oasis, the protein structure on surface
It is destroyed and eliminates.Harmful organic molecule such as formaldehyde, in the presence of high energy electron and the free radical of strong oxidizing property, is resolved into
Water and carbon dioxide.High voltage electric field between emitter stage 2 and receiving pole 3 causes electric charge on partial air band, in the effect of electric field force
Lower motion, collision becomes small between emitter stage 2 and receiving pole 3, between two metal tubes of receiving pole 3 with the dust granule in air
Particle simultaneously makes particle powered again, so repeatedly and then causes on increasing dust granule band electric charge and becomes more next
It is smaller, when charged particle is moved near the emitter stage 2 or receiving pole 3 of oppositely charged, because electrostatic adsorption is sent out
Emitter-base bandgap grading 2 or receiving pole 3 are adsorbed, and uncharged neutrophil granule is then led to by the direction shown in the space along arrow between two metal tubes
Cross.Whole purification process need not can just produce sufficiently large wind speed circulation room air by blower fan, reach soundless energy-saving
Effect.
To ensure that clean unit can produce stronger ion wind and the effect of air cleaning, emitter stage 2 exists with receiving pole 3
Specific when setting in mounting bracket 1, the distance of two closest points of the circumscribed circles of 2 two metal tubes of emitter stage is 28-
50mm.The distance in receiving pole 3 and face nearest apart from receiving pole 3 in emitter stage 2 is that 14-24mm is the circumscribed circle of emitter stage 2
Distance between the line and the plane of emitter stage 2 at center and the center of receiving pole 3, the intersection point of 3 outer surface of receiving pole two is 14-24mm.Connect
The vertical range for receiving pole 3 and the outside tangent plane of the circumscribed circle of two metal tubes of emitter stage 2 is 0-5mm, specific receiving pole 3
The outside of enclosed constructions is formed in the circumscribed circle and two outside tangent planes of two metal tubes and is arranged on metal tube spigot surface windward
Side.
Referring to accompanying drawing 3, receiving pole 3 is that at least 2 strands wires are spirally wound together into the metal wire to be formed.It is every in metal wire
A diameter of 0.1-1mm of one metal wire, pitch B are that the level interval A between 0.8-1.6mm, wire between twisted point is 0.1-
0.4mm.Such setting is difficult adhering dust so that receiving pole 3 adsorbs dust Automatic-falling over the metal lines after powering off, no
Can stick on metal wire so under the influence of time air cleaning clean-up effect.
More than radiation pole 2 and receiving pole 3 be that metal material or outer surface are metal coating, can be tungsten, molybdenum, manganese,
Copper, silver, gold, palladium, platinum, nickel, cobalt, titanium, aluminium, iron are used as alloy of principal component etc. using them.
Referring to accompanying drawing 4, present invention also offers a kind of low temperature plasma air cleaning unit, based on above-mentioned low temperature etc.
Gas ions air cleaning member, its key is that air cleaning member is provided with 2 groups and is oppositely arranged in mounting bracket 1.It is empty
Gas enters from both sides to be purified, and is flowed out after head-on collision from other both sides.
In above example, it is polygonal metal tube or tabular that the structure of emitter stage 2, which is not limited to truncation surface,
Sheet metal is arranged in mounting bracket 1 at an angle or metal folding part is arranged on installs at an angle
On support 1 or round metal tube.
