以下、本発明を添付図面に示す実施形態に基いて説明すると、図1において、2は放電電極、3は対向電極で、針状に形成された放電電極2の先端から間隔をおいてリング状に形成された対向電極3が配設されている。 Explaining based on the embodiment according to the present invention in the accompanying drawings, in FIG. 1, 2 discharge electrode, 3 is the counter electrode, a ring-shaped from the tip of the discharge electrode 2 formed on the needle at a distance the counter electrode 3 are disposed formed. また、放電電極2の基端側にはペルチェモジュール6が熱的に接続されている。 Further, the base end side of the discharge electrodes 2 Peltier module 6 is thermally connected. このペルチェモジュール6は、対の回路板6b,6d間に熱電素子6cを配したもので、上記放電電極2側の回路板6bは絶縁板6aを介して放電電極2に接続されている。 The Peltier module 6, which was arranged thermoelectric element 6c between pairs of circuit board 6b, 6d, the circuit board 6b of the discharge electrode 2 side is connected to the discharge electrode 2 via the insulating plate 6a. また、ペルチェモジュール6の他方の回路板6dの外面側には放熱フィン7が接続されている。 Further, heat radiation fins 7 are connected to the outer surface of the other circuit board 6d of the Peltier module 6.

図中5は放電電極2と対向電極3との間に高電圧を印加する高圧電源部であり、上記ペルチェモジュール6は、放電電極2を冷却することで空気中の水分を放電電極2上に結露させることで、霧化させる水を放電電極2上に生成するものである。 Figure 5 is a high-voltage power supply unit for applying a high voltage between the discharge electrodes 2 and the counter electrode 3, the Peltier module 6, the moisture in the air on the discharge electrode 2 by cooling the discharge electrode 2 be to condensation, it is to produce water for atomizing on the discharge electrode 2. なお、霧化させるための水は特許文献1で示されたものと同様に水タンクから放電電極2に供給されるものであってもよい。 Incidentally, the water or may be supplied to the discharge electrodes 2 of the same water tank to that shown in Patent Document 1 for atomizing.

この静電霧化装置1では、前述のようにペルチェモジュール6で放電電極2を冷却することで空気中の水分を結露させて放電電極2上に結露水を生成する。 In the electrostatic atomizing device 1 generates the condensation water on the discharge electrode 2 by condensing the moisture in the air by cooling the discharge electrode 2 with the Peltier module 6 as described above. この時、放電電極2と対向電極3との間に高電圧を印加すれば、放電電極2上の結露水は対向電極3側に引っ張られて放電電極2の先端に集まり、更に対向電極3との間の放電によってレイリー分裂を起こしてナノメータサイズの静電微粒子水(ミスト)Mとなるとともに対向電極2側に移動し、リング状の対向電極2の中央を通って前方側へと吐出される。 In this case, by applying a high voltage between the discharge electrodes 2 and the counter electrode 3, condensation water on the discharge electrode 2 is gathered at the tip of the discharge electrode 2 is pulled 3 side counter electrode, further a counter electrode 3 discharged to the front side along with the electrostatic water particles (mist) M of nanometer size undergoes Rayleigh fission moves to the counter electrode 2 side, through the center of the ring-shaped counter electrode 2 by the discharge between the .

ここにおいて、上記対向電極3を接地させているグランド線4が放電電極2の側方を通って後方側に引き回されているのであるが、このグランド線4の影響を避けるために、ここでは対向電極3と放電電極2を保持しているベース部分との間に筒状の遮蔽部材11を配して、対向電極3よりも導電性が低い材質からなる上記遮蔽部材11で放電電極2の外周を囲んでいる。 Here, above, but the counter electrode 3 ground lines 4 which grounds the is to through the side of the discharge electrodes 2 are routed to the rear side, in order to avoid the influence of the ground line 4, where by disposing a tubular shielding member 11 between the counter electrode 3 and the base part which holds the discharge electrode 2, in the shielding member 11 electrically conductive than the counter electrode 3 is made of a low material of the discharge electrode 2 It surrounds the outer circumference.

対向電極3に電気的に接続されることでグランド線4を介して接地されている上記遮蔽部材11は、放電電極2の後方へと引き回されたグランド線4に向かっていた電気力線を遮蔽するものであり、このためにミストMの一部が後方側へと流れるというようなことを招くことがなく、最終的には意図している前方側に全ミストMが吐出される。 The shielding member 11 to the counter electrode 3 via a ground line 4 by being electrically connected is grounded, the electric lines of force heading for the ground wire 4 drawn to the rear of the discharge electrodes 2 It is intended to shield a part of the mist M for this purpose without incurring the like that flows to the rear side, eventually all the mist M is ejected to the front side that is intended to.

図2に示すように、上記遮蔽部材11の少なくとも内周面側を絶縁被膜12で覆っていてもよい。 As shown in FIG. 2, at least the inner peripheral surface side of the shielding member 11 may be covered with an insulating film 12. この場合、放電電極2と遮蔽部材11間の電位差を更に低減することができるために、放電電極2の側方に向かっていた電気力線も前方側に向けることができるために、前方側へのミストMの吐出量を更に増大させることができる。 In this case, in order to be able to further reduce the potential difference between the discharge electrodes 2 and the shielding member 11, the electric lines of force heading to the side of the discharge electrodes 2 in order to be able to turn on the front side, the front side the discharge amount of the mist M can be further increased. なお、遮蔽部材11全体が絶縁性材で形成されたものであってもよい。 The overall shield member 11 may be one which is formed of an insulating material.

図3に他の実施形態の一例を示す。 Figure 3 shows an example of another embodiment. これは絶縁被覆が施されているグランド線4を密に巻いたコイル状とし、このコイル状とした部分で対向電極3と上記ベース部との間の放電電極2外周を囲むことによってグランド線4そのものが遮蔽部材11として機能するようにしたものである。 This is a coiled wound tightly ground line 4 are subjected to insulating coating, ground line 4 by surrounding the discharge electrodes 2 outer periphery between the counter electrode 3 and the base portion in the coil-like and portions itself is one that was to function as the shielding member 11.

図4に示すようにグランド線4のコイル状とすることで形成した遮蔽部材11を対向電極3よりも更に前方側にも延長して配置するようにしてもよい。 The shielding member 11 formed by the ground line 4 of the coil shape as shown in FIG. 4 may be further arranged also to extend to the front side of the counter electrode 3. 放電電極2から発生する電気力線の方向を効率良く前方側に向かわせることができるためにミストMの前方吐出量を更に増加させることができる。 The direction of the electric lines of force generated from the discharge electrode 2 can be efficiently further increase the front outlet of the mist M in order to be able to direct to the front side.

また、対向電極3よりも更に前方側にグランド線4のコイル状部分を配置する場合、図5に示すように、対向電極2の外周を囲む部分が無くても、グランド線4の影響で後方へと向かうミストMの流れを少なくすることができるが、図1や図2に示した遮蔽部材11を併用したものや、図4に示したものの方がより好ましいのはもちろんである。 In addition, when further placing a coiled portion of the ground line 4 to the front side of the counter electrode 3, as shown in FIG. 5, even without the portion surrounding the outer periphery of the counter electrode 2, the rear under the influence of the ground line 4 Although it is possible to reduce the flow of the mist M towards the, or that a combination of the shielding member 11 shown in FIGS. 1 and 2, and more preferably towards that shown in FIG. 4 is a matter of course.
