Description

【０００１】
【発明の属する技術分野】
本発明は、放電針の放電により生じたイオンをノズルからエアーと共に噴射するエアー噴射型除電器に関する。
【０００２】
【従来の技術】
従来のエアー噴射型除電器として、除電器本体を片手で持って操作できるようにガン形（ピストル形）としたものがあるが、そのノズルは噴射孔が１個で、エアー及びイオンを線状に噴射するものであった。
【０００３】
【発明が解決しようとする課題】
そのため、エアー及びイオンの噴射範囲が狭く、広い範囲を除電する場合には除電器本体を手で振り動かす回数が非常に多くなり、手が疲労するとか、除電ムラが多くなる等の問題があった。
【０００４】
そこで、本発明の目的は、エアー及びイオンの噴射範囲を従来よりも格段に大きくできるエアー噴射型除電器を提供することにある。
【０００５】
【課題を解決するための手段】
本発明の第１の形態は、除電器本体１が、引き金２を引くと内蔵した弁３が開き、銃身部５中へ外部からエアーが送入されるガン形で、その銃身部５の先端には、互いの雌雄のねじを螺合させて延長筒６が着脱自在に接続され、この延長筒６上に、高電圧発生回路を内蔵した電源ボックス７が搭載されているとともに、延長筒６の先端には、互いの雌雄のねじを螺合させて金属製キャップ８が着脱自在に接続され、またこの延長筒６内の先端部分に設けられた隔壁１０の中央には、キャップ８に内包されてこれをアース電極とする放電針１１が保持されているとともに、該隔壁１０には、エアー通路となる複数の小孔１２が放電針１１の回りに貫通して設けられ、更にこのキャップ８の先端にスピンノズル９が着脱自在に接続されている。
【０００６】
本発明の第２の形態は、除電器本体２１が、高電圧発生回路を内蔵した箱形で、その後壁には、外部からエアー送入するための接続口２２が設けられているとともに、前壁には雄ねじ継手２３が突設され、また除電器本体２１内には、接続口２２と通ずるパイプ２４が貫設され、このパイプ２４の先端に針ホルダ２５により放電針１１を保持され、雄ねじ継手２３に金属製キャップ８を螺合させることにより、放電針１１が該キャップ８をアース電極としてこれに内包され、針ホルダ２５には、パイプ２４と通じるエアー通路となる複数の小孔２６が放射状に設けられ、また前記キャップ８の先端にスピンノズル９が着脱自在に接続されている。
【０００７】
そして、第１の形態及び第２の形態のいずれの場合も、スピンノズル９は、キャップ８の先端に雄ねじ継手１６を螺合させて取り付ける軸受ブロック１４にツイストパイプ１３の基端部１３ａを回転自在に軸受けしたもので、該ツイストパイプ１３の中間部１３ｂが、軸線と直交するＸ方向へ緩やかに湾曲するとともに、先端部１３ｃが、中間部１３ｂに対してＸ方向と直交するＹ方向へ緩やかに湾曲し、先端の噴射口１５が斜めに指向していて、エアー噴射に伴いツイストパイプ１３が自動的に旋回するようになっている。
【０００８】
【発明の実施の形態】
次に、本発明の実施の形態を図面に基づいて詳細に説明する。
【０００９】
図１〜図５は、手で持って操作できるように除電器本体１をガン形（ピストル形）とした実施例である。除電器本体１は、図１に示すように、引き金２を引くと内蔵した弁３が開き、銃底部の接続口４に接続したホース（図示せず）を通じて銃身部５中へエアーが送入されるようになっている。銃身部５の先端には、互いの雌雄のねじを螺合させて延長筒６が着脱自在に接続され、この延長筒６上に、高電圧発生回路（図示省略）を内蔵した電源ボックス７が搭載されている。また、延長筒６の先端には、同じく互いの雌雄のねじを螺合させてキャップ８が着脱自在に接続され、更にこのキャップ７の先端に、同じく互いの雌雄のねじを螺合させてスピンノズル９が着脱自在に接続されている。
【００１０】
延長筒６内の先端部分に一体に設けられた隔壁１０の中央に、キャップ８で内包される放電針１１が保持されている。隔壁１０には、エアー通路となる複数の小孔１２が放電針１１の回りに貫通して設けられている。キャップ８は金属製で、放電針１１に対するアース電極となる。
【００１１】
スピンノズル９の構造について図１、図４及び図５を参照して説明する。スピンノズル９は、ツイストパイプ１３の基端部１３ａを軸受ブロック１４に回転自在に軸受けしている。このツイストパイプ１３の中間部１３ｂは、軸線と直交するＸ方向へ緩やかに湾曲しているが、先端部１３ｃは、中間部１３ｂに対してＸ方向と直交するＹ方向へ緩やかに湾曲して、先端の噴射口１５が斜めに指向しているため、噴射口１５からのエアーの噴射力によってツイストパイプ１３が自動的に旋回するようになっている。
【００１２】
そして、スピンノズル９は、軸受ブロック１４に一体に突設された雄ねじ継手１６をキャップ７の先端部の雌ねじに螺合させることにより、キャップ７の先端に着脱自在に接続されている。
【００１３】
ガン形の除電器はこのように構成されているので、引き金２を引いて弁３を開くことにより銃身部５中に入ったエアーは、放電針１１の回りの複数の小孔１２を通り抜けてキャップ８内に入り、ここで放電針１１の放電にて発生しているイオンを伴ってスピンノズル９のツイストパイプ１３から噴射されるが、そのイオンを伴ったエアーは、ツイストパイプ１３が自動的に旋回するので、螺旋状に拡散して噴射されることになる。
【００１４】
次に、図６〜図９は、設置して使用するように除電器本体２１を箱形とした実施例である。箱形の除電器本体２１には、図示省略した高電圧発生回路が内蔵されている。除電器本体２１の後壁には、ホース（図示せず）を接続する接続口２２が突設され、また除電器本体２１の前壁には、金属製キャップ８と螺合させる雄ねじ継手２３が突設されている。除電器本体２１内には、接続口２２と通ずるパイプ２４が貫設されている。放電針１１は、このパイプ２４の先端において針ホルダ２５により除電器本体２１の前壁に基端部を保持されている。針ホルダ２５には、パイプ２４と通じるエアー通路となる複数の小孔２６が放射状に設けられている。キャップ８は、放電針１１を内包してこれに対するアース電極となっている。キャップ８の先端には、前述したガン形の場合と同じスピンノズル９が雄ねじ継手１６により着脱自在に接続されている。
【００１５】
従って、パイプ２４及び小孔２６を通じてキャップ８内に入ったエアーは、ガン形の場合と同様に、放電針１１の放電にて発生しているイオンを伴ってスピンノズル９のツイストパイプ１３から噴射され、その際にツイストパイプ１３が自動的に旋回することにより、螺旋状に拡散して噴射される。
【００１６】
【発明の効果】
以上述べたように本発明によれば、イオンを伴ったエアーがスピンノズルのツイストパイプから噴射されると、該ツイストパイプが自動的に旋回するので、螺旋状に拡散させて噴射できるため、エアー及びイオンの噴射範囲を従来よりも格段に大きくできる。また、イオンを伴ったエアーが螺旋運動をしながら除電対象物に吹き付けられるので、除塵効果も高い。さらに、組立やメンテナンス性も良い。

A male screw joint 23 protrudes from the wall, and a pipe 24 communicating with the connection port 22 extends through the inside of the static eliminator main body 21. The discharge needle 11 is held at the tip of the pipe 24 by a needle holder 25. By screwing the metal cap 8 to the joint 23, the discharge needle 11 is included in the cap 8 using the cap 8 as a ground electrode, and the needle holder 25 has a plurality of small holes 26 serving as air passages communicating with the pipe 24.

The twisted pipe 13 automatically turns with the air injection.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Next, embodiments of the present invention will be described in detail with reference to the drawings.
[0009]
FIGS. 1 to 5 show an embodiment in which the static eliminator body 1 has a gun shape (pistol shape) so that it can be operated by hand. As shown in FIG. 1, when the trigger 2 is pulled, the built-in valve 3 of the static eliminator body 1 is opened, and air is sent into the barrel portion 5 through a hose (not shown) connected to a connection port 4 at the bottom of the gun. It is supposed to be. An extension tube 6 is detachably connected to the tip of the barrel portion 5 by screwing the male and female screws together. On the extension tube 6, a power supply box 7 containing a high-voltage generating circuit (not shown) is mounted. It is installed. Also, a cap 8 is detachably connected to the tip of the extension cylinder 6 by screwing both male and female screws together, and a screw of the same male and female is screwed to the tip of the cap 7 to spin. The nozzle 9 is detachably connected.
[0010]
At the center of a partition wall 10 provided integrally with the distal end portion in the extension cylinder 6, a discharge needle 11 enclosed by a cap 8 is held. The partition 10 has a plurality of small holes 12 serving as air passages penetrating around the discharge needles 11. The cap 8 is made of metal and serves as a ground electrode for the discharge needle 11.
[0011]
The structure of the spin nozzle 9 will be described with reference to FIG. 1, FIG. 4, and FIG. The spin nozzle 9 rotatably supports a base end 13 a of the twist pipe 13 on a bearing block 14. The intermediate portion 13b of the twist pipe 13 is gently curved in the X direction orthogonal to the axis, but the tip portion 13c is gently curved in the Y direction orthogonal to the X direction with respect to the intermediate portion 13b, Since the injection port 15 at the tip is obliquely directed, the twist pipe 13 automatically turns by the injection force of air from the injection port 15.
[0012]
The spin nozzle 9 is detachably connected to the tip of the cap 7 by screwing a male screw joint 16 integrally provided on the bearing block 14 with a female screw at the tip of the cap 7.
[0013]
Since the gun-shaped static eliminator is configured as described above, the air entering the barrel portion 5 by pulling the trigger 2 and opening the valve 3 passes through the plurality of small holes 12 around the discharge needle 11. The air enters the cap 8 and is ejected from the twist pipe 13 of the spin nozzle 9 along with the ions generated by the discharge of the discharge needle 11. The air with the ions is automatically discharged by the twist pipe 13. As a result, it is spirally diffused and injected.
[0014]
6 to 9 show an embodiment in which the static eliminator main body 21 is box-shaped so as to be installed and used. The box-shaped static eliminator body 21 has a built-in high-voltage generating circuit (not shown). A connection port 22 for connecting a hose (not shown) protrudes from a rear wall of the static eliminator main body 21, and a male screw joint 23 for screwing with the metal cap 8 is formed on a front wall of the static eliminator main body 21. It is protruding. In the static eliminator main body 21, a pipe 24 communicating with the connection port 22 is provided. The base of the discharge needle 11 is held on the front wall of the discharger body 21 by a needle holder 25 at the distal end of the pipe 24. The needle holder 25 has a plurality of small holes 26 radially provided as air passages communicating with the pipe 24. The cap 8 includes the discharge needle 11 and serves as a ground electrode for the discharge needle 11. The same spin nozzle 9 as that of the gun type described above is detachably connected to the tip of the cap 8 by a male screw joint 16.
[0015]
Therefore, the air that has entered the cap 8 through the pipe 24 and the small hole 26 is ejected from the twist pipe 13 of the spin nozzle 9 together with ions generated by the discharge of the discharge needle 11 as in the case of the gun type. At this time, the twist pipe 13 is automatically swirled to be spirally diffused and injected.
[0016]
【The invention's effect】
As described above, according to the present invention, when air with ions is ejected from the twist pipe of the spin nozzle, the twist pipe automatically turns, so that it can be spirally diffused and ejected. In addition, the range of ion injection can be significantly increased as compared with the conventional case. In addition, since the air accompanied by the ions is sprayed onto the object to be neutralized while performing spiral movement, the dust removing effect is high. Further, the assembling and maintenance properties are good.
