Particularly, owing to adopt cheap O shape ring as base side sealing 22 and ejection side sealing 23, so beneficial to reducing cost.
Cell body 24 is multilayer rotary bodies of three layers that are made of minor diameter part 240, middle footpath portion 241, large-diameter portion 242.
Shown in Fig. 4 (a) and (b), be formed with at the central shaft of minor diameter part 240 that to keep the hole of needle electrode 21 be fixed part 243.For example, needle electrode 21 is pressed in fixed part 243 fixes.
As shown in Figure 3 and Figure 4, be formed with introducing port 244 in middle footpath portion 241.Shown in Fig. 6 (b), when mounted, the gas of this introducing port 244 and ion generator body 10 is supplied with road 18 and is communicated with and imports clean air.And, be formed with a pair of jut 245 in middle footpath portion 241.Shown in Fig. 3 (a), when the plane was seen, a pair of jut 245 was formed on 180 ° the opposition side of being separated by on the diameter.
As shown in Figure 3 and Figure 4, be formed with peristome 246, air is imported from the discharge space 247 of external environment condition in large-diameter portion 242 at large-diameter portion 242.
Inside in this cell body 24 has: the receiving space 248 of configuration needle electrode 21, become the part of this receiving space 248 and hold the sharp-pointed front end 210 of needle electrode 21 jet space 249, have this jet space 249 front end spray nozzle part 250, be formed on front end spray nozzle part 250 foremost and the outstanding jet 251 of the sharp-pointed front end 210 of needle electrode 21.Owing to sharp-pointed front end 210 is arranged, so jet 251 becomes the opening of ring-type.
Details near front end spray nozzle part 250, forms passage portion 252 by the sharp-pointed front end 210 of front end spray nozzle part 250 and needle electrode 21 as shown in Figure 5.In the coniform jet space 249 of front end spray nozzle part 250, the cone height b of jet space 249 is than the cone height a height of the sharp-pointed front end 210 that constitutes needle electrode 21, and the apex angle ss of coniform jet space 249 forms the apex angle identical or big (α ≈ β among Fig. 5) with the sharp-pointed front end 210 of needle electrode 21.If it is β is more excessive than α, undesirable owing to injection direction direction expansion to the left and right.Therefore, preferred α=β, and all be acute angle (for example 5 °~30 °).Thus, be combined with benefit again to what prevent ion.
The function of electrode unit 20 then, is described.At first shown in Fig. 6 (a) and (b), electrode unit 20 is fixed on the base side fitting portion 103 and the ejection side fitting portion 104 of ion generator body 10.Side at the ejection side fitting portion 104 of ion generator body 10, be formed with the groove 102 of two bayonet socket joint portions shown in Fig. 3 (d) every 180 degree, in this groove 102 from downside embeds two juts 245 of footpath portion 241, and rise in the time of 245 guiding of this two juts, embed by rotation then and install and fixing.This bayonet socket joint portion is those skilled in the art's a known property mechanical structure, realizes firm fixing.
Shown in Fig. 6 (a) and (b), if this electrode unit 20 is installed on the ion generator body 10, then base side sealing 22 is extruded at above-below direction by the top and base side fitting portion 103 of middle footpath portion 241 following and becomes ellipticity, is adjacent to sealing thus reliably in the contacts side surfaces of the side of minor diameter part 240 and base side fitting portion 103 and everywhere.At this moment, even the top height of middle footpath portion 241 and following some deviation highly a little of base side fitting portion 103, base side sealing 22 absorbs position deviations, also seals reliably.Thus, needn't exceedingly improve mechanical precision, and the path crested reliably on the space of upside (disposing the space of connecting portion 16) and underside gas supply road 18, the clean air that gas is supplied with road 18 can not leak to the upside space.
Similarly, ejection side sealing 23 also becomes ellipticity by following being extruded of the top of large-diameter portion 242 and ejection side fitting portion 104 on above-below direction, be adjacent to sealing thus reliably in the contacts side surfaces of the side of middle footpath portion 241 and ejection side fitting portion 104 and everywhere.At this moment, even following some deviation highly a little of the top height of large-diameter portion 242 and ejection side fitting portion 104, ejection side sealing 23 absorbs position deviation, also seals reliably.Thus, needn't exceedingly improve mechanical precision, and the path crested reliably on the external world of downside and upside gas supply road 18, the clean air that gas is supplied with road 18 can not leak to the external world of downside.
Like this, guarantee that by base side sealing 22 and ejection side sealing 23 gas supplies with the airtight of road 18, spray with jet 251 only from front end spray nozzle part 250.Because the inner sustain that can supply with road 18 to gas is at high pressure, institute helps improving jet power in this so that jet velocity rises.
In addition, electrode unit 20 has such mounting structure: if rise configuration in jut 245 groove 102 along the vertical direction and electrode unit 20, then turn 90 degrees along revolving in the groove 102 of left and right directions and electrode unit 20, the introducing port 244 of footpath portion 241 is communicated with gas supply road 18 then, but, owing to as described above the introducing port 244 in the middle footpath portion 241 between base side sealing 22 and the ejection side sealing 23 is communicated with gas supply road 18, so can maintain high pressure to the inside of electrode unit 20 reliably.
As shown in Figure 4 and Figure 5, path owing to become high pressure in this passage portion 252, improves the speed of spraying from jet 251 along with from jet space 249 to passage portion 252 and stenosis is narrow.
In addition, though near sharp-pointed front end 210 front ends of needle electrode 21, because of corona discharge generates ion, because air is from peristome 246 inflows of large-diameter portion 242, so generate the ion of q.s.
Shown in Fig. 6 (a) and (b), because connecting portion 16 also comprises for example leaf spring 161 such rubber-like parts, so, if the head of needle electrode 21 contacts with the leaf spring 161 of connecting portion 16, then be adjacent to reliably and be electrically connected.Thus, electrode unit 20 constitutes the structure that can load and unload.Because the existence of base side sealing 22, the position of electrical connection isolates from the environment that gas is supplied with in the road 18, to guarantee insulation.
The function and the action of ion generator 1 then, are described.Ion generator 1 uses at the beginning just to fluid system loop supplying clean air.Compressed clean air is supplied with road 18, introducing port 244, receiving space 248, jet space 249 and passage portion 252 by air supply line 40, gas stream port 17, gas, sprays from jet 251.
In addition, apply AC pulsed high voltage generator voltage at needle electrode 21.Apply roughly at the leading section of needle electrode 21 similarly with general ion generator ± E that (E is 7000~10000V) an AC pulse high-voltage and carry out corona discharge, around the needle electrode 21 in large-diameter portion 242, alternately generates cation and anion.So cation, anion in the large-diameter portion 242 are carried on clean air, the discharge space 247 in large-diameter portion 242 sprays to downside.So, by spray clean air around needle electrode 21, as illustrating in front, near the ion that generates needle electrode 21 front ends arrives and destatics the object place.Particularly, owing to improved jet velocity, therefore prevent from combination again to destatic reliably to destaticing object.Also have and reduce the function that dust adheres to needle electrode 21.
Ion generator 1 more than has been described.This ion generator 1 can also have various variant.The ion generator 1 of above-mentioned execution mode is the AC pulsed ion generator that the voltage of being supplied with by the electric system circuit is applied to electrode as the AC pulse voltage.
Yet ion generator 1 also can be to replace the AC pulsed, the voltage of being supplied with by the electric system circuit is applied to the AC type ion generator of needle electrode 21 as common sinuous AC voltage.
In addition, replace AC system also can adopt straight flow.Above-mentioned electrode unit 20 is set at positive electrode and negative electrode.In addition, establish above-mentioned electrode unit 20 with these positive electrodes and negative electrode alternate configurations and constitute.When work, apply positive voltage to generate cation at positive electrode, apply negative voltage to generate anion at negative electrode.This ion generator 1 is to reduce the ion mode of combination again, the cation that generates is mixed and utilizes clean air to blow to destaticing object to destatic with anion.Yet,, perhaps the voltage of being supplied with by the electric system circuit is only only generated anion as negative dc voltage even straight flow as special purpose, only only generates cation to the voltage of being supplied with by the electric system circuit as positive direct-current voltages.In this case, destatic the speed of object,, obtain effect of the present invention so reduce the possibility of combination again owing to accelerate to arrive.
In addition, illustrated that number of poles is four a ion generator.But the number of electrode can the time suitably be selected in design, for example, have five electrode units ion generator, have the ion generator of six electrode units etc., can adopt the ion generator of suitable increase electrode unit.
The present invention according to above explanation, a kind of electrode unit of excellence can be provided, it can be attempted the simplification of implementation structure and reduce cost, and, the inclination that has the electrode of approaching sharp-pointed front end by the receiving space inwall that makes the front end spray nozzle part realizes high-pressure trend, and prevent combination again by improving jet velocity, destatic ability with raising, and be improved simultaneously cost performance and raising destatic this reverse effect of ability.
In addition, provide comprise the kind electrode unit and improve price performance than and destatic the ion generator of ability.
