Tip of the brushstyle of a writing or painting type ion generator 100 as shown in Figure 1, comprising: body 101, nozzle body 102, switch 103, display part 104, air introduction part 105, body 106, electric wire 107 and counter electrode 108.
Body 101, it forms grow crosswise bar-shaped.Electric circuit portion or air flow circuit portion have been taken in its inside.After these electric circuit portions or air flow circuit portion will be described in.
Nozzle body 102, as shown in Figure 2, it comprises the rotary body of triangle taper, is formed with the hole 102a of ejection air at the rotary body tip.Described nozzle body 102 is to make with resin.And resin adopts Teflon (registered trade mark) especially.After reason will be described in.
Switch 103, it is when spraying cation or anion (to call " ion " in the following text), the ON/OFF button that is pressed.
Display part 104, it is to export according to the ion spray volume.In this form, it is LED, by having or not to light a lamp to show whether injection is arranged.
Air introduction part 105, it is the connector that is used to link the inner air and outer air pipe.
Body 106, the one end is attached to air introduction part 105, though the other end is not shown, the other end is to be attached to drive division body (not shown) air supplying part (not shown).
Electric wire 107, one end are drawn in the body 101, and the other end then is connected to drive division body power supply unit (not shown).
Counter electrode 108, it is the drum electrode that is disposed at nozzle body 102 outsides.
The inside formation of pen type ion generator 100 then, is described.
Pen type ion generator 100 shown in Fig. 2,3, disposes sparking electrode 109 and injection portion 110 in spray nozzle part 102.
Sparking electrode 109 is that front end is needle electrode and is disposed in the spray nozzle part 102 ejected ion in spray nozzle part 102.
Injection portion 110 is to be disposed in the nozzle body 102 injection air in spray nozzle part 102.
Nozzle body 102 inside, when when the top is watched, as shown in Figure 2, nozzle body 102 central axis directions, injection portion 110 injection directions and sparking electrode 109 central axis directions are to become consistent.
, as shown in Figure 3, when when laterally watching, sparking electrode 109 and injection portion 110 are the structures with feature.That is sparking electrode 109 central shafts are that tilted configuration becomes that crossing angle α's is acute angle-shaped with respect to spray nozzle part 102 rotary body central shafts.In this case, as long as sparking electrode 109 front ends are positioned on the injection stream of self-injection portion 110 ejection air, decision crossing angle α is to satisfy above-mentioned condition.And sparking electrode 109 front ends are positioned at cylindric counter electrode 108 next doors that are located at spray nozzle part 102 outsides (preferably counter electrode 108 field, inside).At this moment, when counter electrode 108 and sparking electrode 109 front ends were direct subtend, the ion discharging amount can be superfluous, so, between counter electrode 108 and sparking electrode 109 front ends, resinous nozzle body 102 is being arranged.And, as mentioned above,, also adopt Teflon (registered trade mark) and can improve the service life as the resin that is difficult to produce deterioration even ion arrives nozzle body 102.
Then, the power circuit part of being located at body 109 inside is described.As shown in Figure 4, power circuit part, in be provided with booster circuit 111, frequency converter 112 and ion generation testing circuit 113.
Again, switch 103 is that ON/OFF selection wire 107a via electric wire 107 is connected to drive division body air supplying part or power supply unit.
Counter electrode 108 also is connected to drive division body power supply unit via the GND line 107b of electric wire 107.
The also electric property of sparking electrode 109 is connected to booster circuit 111, and frequency converter 112 also is connected to drive division body power supply unit via DC power supply supply line 107c.
Then, the air flow circuit portion that is located at body 109 inside is described.Air flow circuit portion as shown in Figure 5, comprises air hose 114, and air hose 114 1 ends are connected to injection portion 110, and again, air hose 114 other ends are connected to air introduction part 105.And in this manual, so-called air outside the air in atmosphere, also includes the pure air of removing dust etc. with filter, and perhaps, rare gas such as argon gas etc. can use at the gas that removes in electricity, the dedusting.
The action of pen type ion generator 100 then, is described.
When giving as security switch 103 instantly, drive division body air supplying part or power supply unit receive the ON signal, and air supplying part and power supply unit begin to drive.The air supplying part blow air, again, power supply unit is to supply with dc voltage power supply.
As shown in Figure 5, air is the injection portion 110 that arrives via body 106, air introduction part 105 and air hose 114.Injection portion 1 10 is injection airs.
Again, direct voltage is to be applied to ion generation testing circuit 113.Ion generation testing circuit 113 detects the wherein direct current of a part.Electric current flowed when ion was emitted, so, can export and the proportional detection signal of direct current that flows.Import display part 104 and represent that ion produces from the detection signal of ion generation testing circuit 113 outputs.And in this form, display part 104 uses LED, so detection signal is as long as supply with direct current same as before to LED.LED lights a lamp and can confirm that ion produces.
Direct voltage input converter 112.Frequency converter 112 outputs to booster circuit 111 with converting direct-current voltage into alternating-current voltage.
Booster circuit 111 is to boost alternating voltage and produce High AC voltage, makes described High AC voltage be applied to sparking electrode 109.Between the earthing potential counter electrode 108 and this sparking electrode 109 of configuration, form electric field with high voltage via nozzle body 102, cation and anion are to produce alternately on sparking electrode 109 next doors.
Action in the nozzle body 102 is to be described as follows.
As shown in Figure 6, produce cation and anion at sparking electrode 109 front ends.This front end is the limit, injection stream roadside (be preferably in and spray on the stream) that is positioned at self-injection portion 110 ejection air, at cation that produces and injection air before anion combines again, and can be ejected into a distant place from nozzle body 102 hole 102a.
When using this form, spray cation and anion alternately from hole 102a, make removing the charged positive and negative static neutralization of electric object surface and remove.Again, neutralize positive and negative static and can remove dust easily, so, also can be used in the dedusting purposes.
Again, when using this form, cation and anion do not exist not biasedly, so, even near removing electric object, producing ion, also be difficult to produce contrary charged (make same polarity ion concentrate on same position and spray, this ion can make to remove electric object charged).
Again, even remove electric object reflection cation and anion certainly, the counter electrode 109 that also can be configured in nozzle body 102 outsides absorbs, so cation and anion can not be attached to nozzle body 102 and the generation part is charged, its fail safe is better.
Again, adopt self-driven body power supply unit to make lower voltage (for example DC24V) import and produce the structure of high pressure via the DC power supply supply line 107c of electric wire 107 in body 101 internal power circuit portions, can reduce the interference signal that has influence on DC power supply supply line 107c next door ON/OFF selection wire 107a or GND line 107b and produce, or the misgivings of lessen any interference signal overlap DC power supply supply line 107c.
And, be the direct current power signal of comparison low pressure (for example DC24V) among the DC power supply supply line 107c, so, the misgivings of electric induction etc. can be reduced.
And, because be obliquely installed sparking electrode 109, so, can and put the structure and the air injection structure of supporting needle electrode, and make that device can miniaturization.
The AC system device was described in above-mentioned example, still, also can uses to apply positive high voltage produces cation at sparking electrode 109 honest streaming device, perhaps, applied negative high-voltage produces anion at sparking electrode 109 negative straight flow device.In this case, power circuit part becomes the just high-tension circuit of generation.
Again, in this form, be confined to the pen type hand-held ion generator and did explanation, still, the present invention is not limited to pen type person is also applicable to rifle type hand-held ion generator.Even rifle type hand-held ion generator, the invention effect that also can obtain as above to illustrate.
