例えば清掃装置に用いられる流体等の噴出装置は、 圧縮空気等の気体を噴出ノ ズルの噴出口から噴出して被清掃部の塵や埃などを排除する。 また洗浄装置に用 いられる流体等の噴出装置は、 水や洗浄液などの液体または粉状あるいは粒状の 研掃材を高圧空気の圧力を介して噴出ノズルから噴出させて被洗浄部の汚れを洗 い落として除去する。  For example, an ejection device for a fluid or the like used in a cleaning device ejects a gas such as compressed air from an ejection port of an ejection nozzle to remove dust and dirt from a portion to be cleaned. In addition, a device for ejecting a fluid or the like used in a washing device is configured to wash a dirt on a portion to be washed by ejecting a liquid such as water or a washing liquid or a powdery or granular abrasive from an ejection nozzle through the pressure of high-pressure air. Remove and remove.
したがって、 従来の流体等の噴出ノズル及び噴出装置は、 噴出流体等ををノズ ルの上流側から高圧空気の圧力で押し出すようにして噴出させる構造を採る。  Therefore, the conventional ejection nozzle and ejection device for fluid or the like adopt a structure in which the ejection fluid or the like is ejected from the upstream side of the nozzle by the pressure of high-pressure air.
この構造は、 噴出ノズルを可撓性の円筒体によって形成することによって噴出 時にノズルを旋回運動させて噴出流体を回転拡散させるようにした特開平 1 1一 1 2 3 3 5 0号開示の特異な構成のノズルにあっても、 同様である。  This structure is disclosed in Japanese Unexamined Patent Application Publication No. 11-123500, in which the ejection nozzle is formed of a flexible cylinder so that the nozzle is swirled during ejection to rotate and diffuse the ejection fluid. The same applies to a nozzle having a different configuration.
特開 2 0 0 0— 5 1 8 0 0の洗浄装置は、 素材自体の柔軟性によって流体噴出 時に旋回運動する上記した特異な構成の噴出ノズルを用いる。 この洗浄装置は、 図 5に概略的に示すように、 水供給源 Aと圧縮空気供給源 Bと洗剤供給源 Cと噴 出ノズル E、 並びに噴射ノズル Eと各供給源 A〜Cとを連絡する管路 F (上流側 の分岐管路 F1〜F3と下流側の主管路 F4とから成る） を備える。 そして、 本装置で は、 水供給源 Aに圧縮空気供給源 Bから圧縮空気を送り込み、 あるいは洗剤供給 源 Cに圧縮空気供給源 Bから圧縮空気を送り込み、 各分岐管路 F1〜F3から圧送さ れる流体を、主管路 F4との接続部に設けた切替え手段 Dを操作することによって、 噴出ノズル Fから水、 洗剤、 あるいは圧縮空気を噴出させる。  The cleaning device disclosed in Japanese Patent Application Laid-Open No. 2000-510800 uses a jet nozzle having the above-described peculiar configuration that makes a revolving motion at the time of jetting a fluid due to the flexibility of the material itself. As shown schematically in Fig. 5, this cleaning device connects a water supply source A, a compressed air supply source B, a detergent supply source C, and a jet nozzle E, and a jet nozzle E with each of the supply sources A to C. Pipeline F (consisting of an upstream branch pipeline F1 to F3 and a downstream main pipeline F4). In this device, compressed air is supplied from the compressed air supply source B to the water supply source A, or compressed air is supplied from the compressed air supply source B to the detergent supply source C, and is supplied from each branch line F1 to F3. By operating the switching means D provided at the connection with the main pipeline F4, water, detergent or compressed air is ejected from the ejection nozzle F.
し力、し、 従来の装置は、 上記した特開 2 0 0 0 - 5 1 8 0 0に代表されるよう に、 水や洗剤など噴出流体の供給源 A， Cにそれぞれ圧縮空気を送り込み、 加圧 して噴出ノズル Eまで供給する。 このため、 いきおい圧縮空気供給源 Bに強力な ものを使用しなければならず、 水供給源 Aや洗剤供給源 Cも大きくなり、 装置全 体が大型化する。 As shown in the above-mentioned Japanese Patent Application Laid-Open No. 2000-518, the conventional apparatus sends compressed air to supply sources A and C of jet fluid such as water and detergent, respectively. Pressurize and supply to jet nozzle E. Therefore, a powerful compressed air supply B Must be used, the water supply source A and the detergent supply source C become large, and the entire equipment becomes large.
また、 噴出ノズル機構は、 操作性を考慮して上記切替手段を搭載したガンタイ プのようなものが用いられるが （図 5中、 符合 E ' 参照） 、 この機構 E ' に 3つ の管路 F1〜F3が接続されることになるため、 これらの管路が邪魔になってノズル Eによる洗浄等の作業をしづらくなる。  For the ejection nozzle mechanism, a gun type equipped with the above-mentioned switching means is used in consideration of operability (see reference numeral E 'in Fig. 5), but this mechanism E' has three conduits. Since F1 to F3 are connected, these conduits hinder the work such as cleaning with the nozzle E.
更には、 噴出流体を異なる液体などに変更するには、 供給源 A， Cとなるタン ク自体を取り換えなければならず、 やっかいである。  Furthermore, changing the jet fluid to a different liquid, etc., requires replacing the tanks that are the source A and C, which is troublesome.
本発明の目的は、 装置全体をコンパク ト化できるばかりでなく、 噴出ノズルの 操作を楽に行え、 しかも噴出流体の交換も容易に行うことのできる、 ノズルと噴 出装置を提供することにある。  An object of the present invention is to provide a nozzle and a jetting device which can not only make the entire device compact, but also can easily operate the jetting nozzle and easily exchange the jetting fluid.

In addition, as the gas is ejected from the ejection port through the flow path, at least the front part of the outer nozzle and the inner nozzle including the two ejection ports rotates and at the same time, the gas is supplied through the passage. The secondary medium is sucked from the source, and is ejected from the outlet of the secondary medium in a mixed state with the gas.

外ノズルの外周面には、 外ノズルと内ノズルの旋回運動を助けるバランサを取 付けるのが望ましい。 パランサは、 外ノズルの先端部外周などに単数あるいは外 ノズルの長さ方向に適宜の間隔を置いて複数取付けられる。 It is desirable to mount a balancer on the outer peripheral surface of the outer nozzle to assist the swiveling motion of the outer nozzle and the inner nozzle. The balancer may be singular or A plurality of nozzles are attached at appropriate intervals in the length direction of the nozzle.
また、 外ノズルの外方には、 外ノズルと内ノズルの前記旋回運動を規制する規 制部材を設けると良い。 規制部材は、 外ノズルと内ノズルの旋回運動部の全体を 取り囲む前方拡開型のラッパ状を成すものあるいは外ノズルの旋回運動部を部分 的に囲むリング部材から成るものなどが考えられる。 規制部材の先端には、 必要 に応じてブラシを取り付け、 このブラシの毛を旋回流と衝突させることによって 可動させるようにしても良い。  Further, it is preferable that a restricting member for restricting the turning movement of the outer nozzle and the inner nozzle be provided outside the outer nozzle. The restricting member may be a front-opening flared type surrounding the entire swirling portion of the outer nozzle and the inner nozzle, or a ring member partially surrounding the swirling portion of the outer nozzle. A brush may be attached to the tip of the regulating member as necessary, and the brush may be moved by colliding the bristles of the brush with the swirling flow.
外ノズルと内ノズルは、 可撓性を有する合成樹脂製やゴム製のチューブ材によ つて形成される。 外ノズルと内ノズルは、 個別に材料の異なる可撓性材料によつ て形成されるようにしても良い。  The outer nozzle and the inner nozzle are formed of a flexible synthetic resin or rubber tube material. The outer nozzle and the inner nozzle may be formed of flexible materials that are different from each other.
噴出用の加圧気体及び副次媒体は、 ノズルゃ噴出装置の使用目的に応じて適宜 選択される。 例えば、 加圧気体をコンプレッサ等の供給源から圧送される圧縮空 気とし、 副次媒体を洗浄用の液体あるいは研掃材または塗料とする。 洗浄用の液 体は、 洗剤と研掃材との混合液であっても良い。  The pressurized gas and secondary medium for jetting are appropriately selected according to the purpose of use of the nozzle / jetting device.

In the nozzle and the jetting device of the present invention, the pressurized gas is jetted from the first communication passage, through the flow path of the outer nozzle, and from the gas outlet at the distal end. The secondary medium is ejected from the secondary medium outlet at the distal end through the inner passage of the inner pipe. The secondary medium is not sent to the supply side of the secondary medium by applying a positive pressure as in the past, but is sent by the negative pressure generated near the gas outlet as the gas is ejected. Automatically extracted from the The sucked secondary medium is discharged forward by the swirling motion of the outer nozzle and the inner nozzle, riding on the flow of gas that is diffusely jetted out.

発明を実施するための最良の形態  BEST MODE FOR CARRYING OUT THE INVENTION
以下、 本発明の実施の形態を図面を参照しつつ詳説する。  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
本流体噴出装置は、 流体噴出ガン 1と、 加圧空気供給源 2と、 洗浄液貯溜容器 3とを備える。  The fluid ejection device includes a fluid ejection gun 1, a pressurized air supply source 2, and a cleaning liquid storage container 3.
流体嘖出ガン 1は、 ガン本体 4の先端に連結体 5を介してノズル 6を取付けて 成る。 連結体 5は、 内部に気体が通過可能な通過路 7を有する。 連結体 5の周面 下部には、 通過路 7と連通する接続孔 8が設けられている。 接続孔 8には、 開閉 弁操作部材 9を介して洗浄液貯溜容器 3が着脱自在に接続されてている。  The fluid ejection gun 1 is configured by attaching a nozzle 6 to the tip of a gun body 4 via a connector 5. The connecting body 5 has a passage 7 through which gas can pass. A connection hole 8 communicating with the passage 7 is provided in a lower portion of the peripheral surface of the connecting body 5. The cleaning liquid storage container 3 is detachably connected to the connection hole 8 via an on-off valve operating member 9.
連結体 5の前端には、 ノズル 6の取付部 1 1が固定されている。 ノズル取付部 1 1は、 内部に貫通孔 1 2を有する。 ノズル取付部 1 1の前端には、 外ノズル 1 3の基端部が固定され、外ノズル 1 3の内部には内ノズル 1 4が揷通されている。 外ノズル 1 3の内面と内ノズル 1 4の外面との間に生じる間隙は、 気体の流路 1 5を形成する。 この流路 1 5は、 ノズル取付部 1 1の貫通路 1 2から連結体5の 通過路 7に連通している。 内ノズノレ 1 4は、 その後部が、 ノズル取付部 1 1の貫 通孔 1 2から連結体 5の通過路 7に入り込んだ後、 連結体 5の接続孔 8へと延び て、 開閉弁操作部材 9に接続されている。 内ノズル 1 4の内部に形成される通路 は、 洗浄液の通路 1 6を成す。 At the front end of the connecting body 5, a mounting portion 11 of the nozzle 6 is fixed. The nozzle mounting portion 11 has a through hole 12 inside. The base end of the outer nozzle 13 is fixed to the front end of the nozzle mounting portion 11, and the inner nozzle 14 passes through the inside of the outer nozzle 13. The gap formed between the inner surface of the outer nozzle 13 and the outer surface of the inner nozzle 14 forms a gas flow path 15. The flow path 15 communicates from the through path 12 of the nozzle mounting section 11 to the through path 7 of the connector 5 . The inner nose 14 extends from the through hole 12 of the nozzle mounting portion 11 into the passage 7 of the connecting body 5 and then to the connecting hole 8 of the connecting body 5, and the opening / closing valve operating member. Connected to 9. The passage formed inside the inner nozzle 14 forms a passage 16 for the cleaning liquid.
外ノズル 1 3は、 その全体が例えばナイロン、 テフロン、 ポリウレタン、 ポリ プロピレンなどの可撓性を有する合成樹脂製のチューブ材から成る。 内ノズル 1 4も、 少なくとも外ノズル 1 3内に配される部分が同様の合成樹脂製のチューブ 材から成る。 外ノズル 1 3と内ノズル 1 4は、 内ノズル 1 4と外ノズル 1 3の間 の流路 1 5中を気体が通過し、 流路 1 5先端の噴出口 1 5 aより気体が噴出する ことにより、 材質の持つ柔軟性によって外ノズル 1 3の固定された基端部より前 方の部分が、 旋回運動を行う。 The entire outer nozzle 13 is made of a tube made of a flexible synthetic resin such as nylon, Teflon, polyurethane, or polypropylene. The inner nozzle 14 also has at least a portion disposed in the outer nozzle 13 made of a similar synthetic resin tube. In the outer nozzle 13 and the inner nozzle 14, the gas passes through the flow path 15 between the inner nozzle 14 and the outer nozzle 13, and the gas is jetted from the outlet 15 a at the end of the flow path 15. Due to the flexibility of the material, the front end of the outer nozzle 13 The other part performs a swiveling motion.
内ノズル 1 4の通路 1 6先端にある噴出口 1 6 aは、 外ノズル 1 3の流路 1 5 先端にある噴出口 1 5 aよりも若干外方、 すなわち、 上記流路 1 5から気体が噴 出される際に当該噴出口近傍に形成される負圧域に突出している。  The jet 16a at the end of the passage 16 of the inner nozzle 14 is slightly outside the jet 15a at the end of the flow path 15 of the outer nozzle 13, i.e., the gas flows from the flow path 15 above. Protrudes into a negative pressure region formed near the jet port when jetted.
外ノズル 1 3の外周には、 外ノズル 1 3の先端部と長さ方向に間隔をおいた所 定の位置とに合成樹脂製のバランサ 1 7が複数取付けられている。 バランサ 1 7 は、 ノズル 6の上記した旋回運動に慣性力を付与して旋回を効率良く行わせる。 外ノズル 1 3の外方には、 前方にゆくにしたがって大径を成すラッパ状の規制 ガイド 1 8が取付けられている。 規制ガイド 1 8の開口端 1 8 aは、 ノズル 6よ りも前方に張り出している。 規制ガイド 1 8は、 合成樹脂材によって形成され、 ノズル 6の旋回運動をその内周面に沿って行わせる。 これにより、 ノズル 6の動 きが一定の範囲に規制されると同時に規制ガイド 1 8の開口端 1 8 aに沿って気 体等が噴出される。  A plurality of balancers 17 made of synthetic resin are attached to the outer periphery of the outer nozzle 13 at the tip of the outer nozzle 13 and at predetermined positions spaced apart in the length direction. The balancer 17 applies an inertial force to the above-described swiveling motion of the nozzle 6 to efficiently perform swirling. Outside the outer nozzle 13, a trumpet-shaped regulating guide 18 having a larger diameter as it goes forward is attached. The open end 18 a of the restriction guide 18 projects forward from the nozzle 6. The restriction guide 18 is formed of a synthetic resin material, and causes the nozzle 6 to perform a swiveling motion along its inner peripheral surface. Thereby, the movement of the nozzle 6 is restricted to a certain range, and at the same time, a gas or the like is ejected along the opening end 18a of the restriction guide 18.
加圧空気供給源 2としてエアコンプレッサが用いられ、 供給管路 1 9を介して ガン本体 4と接続されている。 ガン本体 4は、 引き金用レバー 2 0が引かれるこ とによつて連結体 5の通過路 7に加圧空気供給源 2から加圧空気を送り込む。 送 り込まれた加圧空気は、 通過路 7から貫通孔 1 2を経て外ノズル 1 3の流路 1 5 に侵入する。 引き金 2 0を引いている間、 供給管路 1 9と通過路 7並びに貫通孔 1 2及び外ノズル 1 3の流路 1 5とは連通状態を維持し、 引き金 2 0を戻すこと で、 供給管路 1 9と通過路 7との間は遮断される。  An air compressor is used as the pressurized air supply source 2, and is connected to the gun body 4 via a supply pipe 19. The gun body 4 sends the pressurized air from the pressurized air supply source 2 to the passage 7 of the connecting body 5 when the trigger lever 20 is pulled. The sent pressurized air enters the passage 15 of the outer nozzle 13 from the passage 7 through the through hole 12. While the trigger 20 is being pulled, the supply line 19 and the passage 7 as well as the passage 15 of the through-hole 12 and the outer nozzle 13 are kept in communication, and the trigger 20 is returned to supply. The connection between the pipeline 19 and the passage 7 is blocked.
洗剤液の貯溜容器 3は、 連結体 5の前記した接続孔 8に接続された開閉弁操作 部材 9の上流に着脱自在に取付けられている。 貯溜容器 3は、 洗剤液を加圧する ことなく内部に貯溜する。 貯溜容器 3には、 揷入管 2 1が容器底部に向けて延び ている。 挿入管 2 1は、 開閉弁操作部材 9を介して内ノズル 1 4の基端部と連通 する。  The detergent liquid storage container 3 is detachably mounted upstream of the on-off valve operating member 9 connected to the connection hole 8 of the connecting body 5. The storage container 3 stores the detergent liquid therein without applying pressure. The storage container 3 has an inlet pipe 21 extending toward the container bottom. The insertion pipe 21 communicates with the base end of the inner nozzle 14 via the on-off valve operating member 9.
なお、 図中符合 1 0は開閉弁操作部材 9の操作レバー、 2 2は規制ガイド 1 8 の所要位置に形成した孔部、 2 3は貯溜容器 3の蓋体、 2 4は容器本体を示す。 貯溜容器 3の着脱機構は、 ネジ式、 嵌め込み式など適宜の手段が採用される。 上記構成の流体噴出装置の使用状態を説明する。 先ず、 この装置で加圧空気と洗剤液とを併用して噴出する場合、 洗剤液の貯溜 容器 3を装着し、 開閉弁操作部材 9の操作レバー 1 0を開位置にして揷入管 2 1 と内ノズル 1 4とを連通状態とする。 . In the drawing, reference numeral 10 denotes an operation lever of the on-off valve operating member 9, 22 denotes a hole formed at a required position of the regulation guide 18, 23 denotes a lid of the storage container 3, and 24 denotes a container body. . As a mechanism for attaching and detaching the storage container 3, an appropriate means such as a screw type or a fitting type is adopted. The usage state of the fluid ejection device having the above configuration will be described. First, when the pressurized air and detergent liquid are jetted together with this device, the detergent liquid storage container 3 is installed, the operating lever 10 of the on-off valve operating member 9 is set to the open position and the inlet pipe 21 is connected to the inlet pipe 21. The inner nozzle 14 is in communication. .
次いで、 加圧空気供給源 2たるコンプレッサを駆動させ、 ガン本体 4の引き金 2 0を引くと、 コンプレッサ 2から圧縮空気が供給管路 1 9、 通過路 7、 貫通路 1 2を経て外ノズル 1 3の流路 1 5に流れ （空気の流れるこれら一連の経路は第 一の連通路を成す） 、 流路 1 5先端の嘖出口 1 5 aから勢いよく噴出される。 こ のとき、 外ノズル 1 3と内ノズル 1 4は、 ともにその前方部が可撓性合成樹脂材 によって形成され、 かつ基端部が固定されている一方、 先端部が自由端になって いるため、 噴出口 1 5 aを有する自由端が暴れるようにして旋回運動を行う。 こ の旋回運動は、 外ノズル 1 3の外方に設けられた規制ガイド 1 8によって径方向 一定の範囲に規制される。 規制ガイド 1 8の内面に沿って、 ノズル 6は規則的な 旋回運動を行う。 また、 外ノズル 1 3の周囲に取付けられたバランサ 1 7によつ てノズル 6の旋回運動は安定したものとなる。  Next, when the compressor as the pressurized air supply source 2 is driven and the trigger 20 of the gun body 4 is pulled, the compressed air from the compressor 2 passes through the supply pipe 19, the passage 7, the through-hole 12, and the outer nozzle 1 3 flows into the flow path 15 (these series of paths through which the air flows form the first communication path), and is vigorously ejected from the flow outlet 15 a at the end of the flow path 15. At this time, the front portions of the outer nozzle 13 and the inner nozzle 14 are both formed of a flexible synthetic resin material, and the base portion is fixed, while the tip portion is a free end. Therefore, the swiveling motion is performed such that the free end having the spout 15 a becomes rampant. This swirling motion is regulated in a radially constant range by a regulation guide 18 provided outside the outer nozzle 13. Along the inner surface of the regulation guide 18, the nozzle 6 makes a regular swiveling movement. In addition, the balancer 17 attached around the outer nozzle 13 makes the turning motion of the nozzle 6 stable.
外ノズル 1 3の流路 1 5から空気が勢いよく噴出されると、 内ノズル 1 4の内 部通路 1 6の噴出口 1 6 aに負圧力が作用し、 内ノズル 1 4の内部流路 1 5と挿 入管 2 1から洗剤容器内の洗剤液を吸い上げる （洗剤液の流れるこの経路は第二 の連通路を成す） 。 そして、 洗剤液は、 外ノズル 1 3からの噴出空気に乗って空 気との混合状態で霧状に放出される。 上記したように外ノズル 1 3と内ノズル 1 4は旋回運動を行いながら空気と洗剤液を噴出するので、 これらの混合流体は勢 いが増幅された渦卷流となって、 被洗浄面に擦るようにして衝突する。 ノズル 6 の旋回運動は、 規制ガイド 1 8によって一定の範囲に規制され、 噴出エネルギの 無駄を生じさせないので、 固定ノズルから単純に前方に噴出されるものに比べて 強い衝突力もしくは洗浄力が得られる。  When air is vigorously jetted from the flow path 15 of the outer nozzle 13, a negative pressure acts on the ejection port 16 a of the inner passage 16 of the inner nozzle 14, and the inner flow path of the inner nozzle 14 The detergent liquid in the detergent container is sucked up from 15 and the insertion pipe 21 (this path through which the detergent liquid flows forms a second communication passage). Then, the detergent liquid is ejected in the form of a mist in a state of being mixed with the air on the jet air from the outer nozzle 13. As described above, since the outer nozzle 13 and the inner nozzle 14 eject the air and the detergent liquid while performing a swirling motion, these mixed fluids form a swirl flow with an increased momentum, and form a swirl flow on the surface to be cleaned. Collide as if rubbing. The swirling motion of the nozzle 6 is regulated to a certain range by the regulation guide 18 and does not waste the ejection energy, so that a stronger collision force or cleaning power can be obtained as compared with the one simply ejected forward from the fixed nozzle. Can be
流体噴出ガンは、ガン本体 4に単一の供給营路 1 9のみが接続されているので、 噴出作業の際に管路が邪魔になることはない。 また、 洗剤の貯溜容器 3がガン本 体 4とノズル 6との間に位置しているので、 ガン本体 4の操作バランスも良好と なる。  In the fluid ejection gun, since only a single supply line 19 is connected to the gun body 4, the pipe does not obstruct the ejection operation. In addition, since the detergent storage container 3 is located between the gun body 4 and the nozzle 6, the operation balance of the gun body 4 is improved.
洗剤液を変更もしくは補充する場合、 貯溜容器 3を取り外して、 異なる洗剤液 あるいは補充された洗剤液の貯溜容器 3を取付けるだけで良!/、。 When changing or refilling the detergent solution, remove reservoir 3 and use a different detergent solution. Or just install the reservoir 3 for the replenished detergent solution!
なお、 規制ガイド 1 8の孔部 2 2は、 外部空気を取り込み、 規制ガイド 1 8の 内面に沿って噴出させることで、 ノズルの旋回噴出時に当該孔部 2 2から規制ガ イド 1 8先端にかけて流れる誘導流を生じさせる。  The hole 22 of the regulation guide 18 takes in outside air and blows it out along the inner surface of the regulation guide 18, so that when the nozzle is swirled, the hole 22 extends from the hole 22 to the tip of the regulation guide 18. A flowing induced flow is created.
開閉弁操作部材 9の操作レバー 1 0を閉状態にして、 ガン本体 4の引き金レバ 一 2 0を引くと、 上記したと同様に、 コンプレッサ 2から送られた圧縮空気が通 過路 7と貫通孔 1 2を経て外ノズル 1 3の流路 1 5を通過し、 先端の噴出口 1 5 aから噴出される。 一方、 洗剤液の挿入管 2 1は、 開閉弁操作部材 9によって内 ノズル 1 4の内部通路 1 6 と遮断されている。 したがって、 外ノズル 1 3と内ノ ズル 1 4は、 上記したと同様に旋回運動を行いながらも、 空気のみの旋回流を放 出する。  When the operating lever 10 of the on-off valve operating member 9 is closed and the trigger lever 120 of the gun body 4 is pulled, the compressed air sent from the compressor 2 passes through the passage 7 and the through hole as described above. After passing through 12, it passes through the flow path 15 of the outer nozzle 13, and is ejected from the ejection port 15 a at the tip. On the other hand, the detergent liquid insertion pipe 21 is shut off from the internal passage 16 of the inner nozzle 14 by the on-off valve operating member 9. Therefore, the outer nozzle 13 and the inner nozzle 14 emit a swirling flow of only air while performing a swirling motion in the same manner as described above.
こうした空気のみの旋回流は、 洗浄の前処理としての埃や軽い附着物の吹き飛 ばし除去に効果的である。 また、 洗浄液吹き付け後や塗料塗布後の対象面の乾燥 処理にも役立つ。  This swirling flow of air alone is effective for blowing off dust and light attachments as a pretreatment for cleaning. It is also useful for drying the target surface after spraying the cleaning liquid or applying paint.
図 3を参照しつつ本発明の別の実施形態に係る流体噴出装置を説明する。 この装置は、 図 1の流体噴出装置と基本的な構造を同じくし、 これに加えて、 ノズル 6に設けられた規制ガイド 1 8の開口端 1 8 aに環状ブラシ 3 0を取付け たものである。 環状ブラシ 3 0は、 その毛 3 1が規制ガイド 1 8の軸線方向に沿 つて植設されている。 なお、 図 2中、 図 1の装置と同一部材には同一符合を付し てある。  A fluid ejection device according to another embodiment of the present invention will be described with reference to FIG. This device has the same basic structure as the fluid ejection device shown in Fig. 1, and additionally has an annular brush 30 attached to the open end 18a of the regulating guide 18 provided on the nozzle 6. is there. The annular brush 30 has its bristle 31 implanted along the axial direction of the regulating guide 18. In FIG. 2, the same members as those in the apparatus in FIG. 1 are denoted by the same reference numerals.
規制ガイド 1 8の内周に沿って旋回する内ノズル 1 4と外ノズル 1 3から噴出 された空気と洗浄液の混合流体は、 規制ガイド 1 8の内周面に沿って開口端 1 8 aから拡径方向に噴出される。 規制ガイド 1 8の軸線方向に沿って延びる環状プ ラシ 3 0の各毛 3 1は、 旋回しながら噴出するこの混合流体に衝突するときに拡 径方向に曲げられ、 衝突から逸れたときに復帰する。 したがって、 環状ブラシ 3 0は、 旋回流とともに順次拡径する方向に曲げられる毛 3 1の位置も旋回する。 この拡径方向に曲げられる毛 3 1の位置が旋回することで、 被洗浄面にブラシ 3 0を当てることにより、 ブラシ 3 0の旋回運動と噴出する混合流体の旋回動によ つて被洗浄面はむらなく洗浄されることになる。 上記した 2つの実施形態では、 内ノズルから噴出される媒体として洗浄液を用 いたが、 本発明はこれに限定されるものではなく、 内ノズルの内部通路を通過可 能な径の粉状あるいは粒状をした研掃材を使用しても良い。 研掃材は、 単独であ るいは液体と混合した状態で使用される。 研掃材も同様に貯溜容器に収容されて 流体噴射ガンのガン本体に着脱自在に取付けられる。 The mixed fluid of air and cleaning liquid ejected from the inner nozzle 14 and the outer nozzle 13 rotating along the inner circumference of the regulating guide 18 flows from the open end 18 a along the inner circumferential surface of the regulating guide 18. It is ejected in the diameter expansion direction. Each bristle 31 of the annular brush 30 extending along the axial direction of the regulating guide 18 is bent in the radial direction when colliding with the mixed fluid ejected while turning, and returns when deviating from the collision. I do. Therefore, the annular brush 30 also turns the position of the bristles 31 that are bent in the direction in which the diameter gradually increases with the swirling flow. By rotating the position of the bristles 31 that are bent in the radial direction, the brush 30 is applied to the surface to be cleaned, and the swirling motion of the brush 30 and the swirling motion of the jetted mixed fluid cause the surface to be cleaned. Will be washed evenly. In the two embodiments described above, the cleaning liquid is used as the medium ejected from the inner nozzle. However, the present invention is not limited to this, and powder or granules having a diameter capable of passing through the inner passage of the inner nozzle are used. You may use the abrasive material which did the following. The abrasive is used alone or in a mixture with a liquid. The abrasive material is also stored in the storage container and is detachably attached to the gun body of the fluid ejection gun.
本発明では、 加圧気体の供給源として、 エアゾール式の圧縮空気供給容器を用 いることもできる。 この場合、 圧縮空気供給容器上部のノズル体に図 1と図 3の 実施例における連結体 5を連結し、 この連結体 5に本発明に係るノズル 6と副次 媒体の貯溜容器 3を固定する。 図 4はその概念構成図を示す。 図 1及び図 3と同 一部材には同一符合を付し、 その説明を省略する。 なお、 貯溜容器 3には、 小型 のものが用いられる。  In the present invention, an aerosol-type compressed air supply container can be used as a supply source of the pressurized gas. In this case, the connecting body 5 in the embodiment of FIGS. 1 and 3 is connected to the nozzle body above the compressed air supply container, and the nozzle 6 and the secondary medium storage container 3 according to the present invention are fixed to this connecting body 5. . Figure 4 shows the conceptual configuration diagram. 1 and 3 are denoted by the same reference numerals, and description thereof will be omitted. Note that a small storage container 3 is used.
この実施形態では、 流体噴射ガンは用いられない。 ノズル体 4 0を持つエアゾ ール式圧縮空気供給容器 4 1がこれに換わる。 コンプレッサや流体噴射ガンを用 いるものに比べて更にコンパクトイ匕される。  In this embodiment, no fluid injection gun is used. An aerosol type compressed air supply container 41 having a nozzle body 40 replaces this. It is more compact than those using a compressor or fluid injection gun.

産業上の利用可能性  Industrial applicability
本発明に係るノズルは、加圧気体供給源から気体を外ノズルの流路に通過させ、 気体の嘖出口から噴出するときの負圧によって内ノズルの内部通路より副次媒体 供給源から副次媒体を吸引し、 副次媒体を気体との混合状態で噴出させるので、 副次媒体を加圧することなくノズルから噴出できる。 しかも、 副次媒体を気体の 噴出力によって気体中に霧化混合して拡散放出できる。  The nozzle according to the present invention allows the gas from the pressurized gas supply source to pass through the flow path of the outer nozzle, and the secondary pressure from the secondary medium supply source through the internal passage of the inner nozzle due to the negative pressure when the gas is ejected from the gas outlet. Since the medium is sucked and the secondary medium is ejected in a mixed state with the gas, the secondary medium can be ejected from the nozzle without pressurizing. In addition, the secondary medium can be atomized and mixed into the gas by the jetting power of the gas and diffused and released.
また、 外ノズルの流路を気体が通過するときに、 外ノズルと内ノズルは旋回運 動をするので、 副次媒体と気体の混合物を、 旋回流にして噴出させることができ る。 旋回流は、 目的物に到達したときに、 目的物表面を擦るようにして衝突する ので、 清掃や洗浄にいたって効果的である。 When the gas passes through the flow path of the outer nozzle, the outer nozzle and the inner nozzle rotate. As a result, the mixture of the secondary medium and the gas can be ejected in a swirling flow. When the swirling flow reaches the target object, it collides with the surface of the target object by rubbing it, which is effective for cleaning and cleaning.
外ノズルの外方にノズル旋回運動の規制部材を配設したときは、 ノズルを規制 部材内面に沿って旋回させることができ、 ノズルからの噴出物を一定範囲に集中 させることができる。  When the regulating member for the nozzle swirling motion is provided outside the outer nozzle, the nozzle can be swung along the inner surface of the regulating member, and the ejected matter from the nozzle can be concentrated in a certain range.
規制部材をラッパ状に形成し、 その開口端に環状ブラシを取付ければ、 気体等 が旋回しながら噴出する際にブラシの毛を順次外方に撓ませ、 かつ復帰させるの で、 目的物表面をブラシの毛によってむらなく擦ることができる。  If the restricting member is formed in a trumpet shape and an annular brush is attached to the opening end, the bristles of the brush are sequentially bent outward and return when gas or the like is ejected while swirling, so that the object surface Can be evenly rubbed with the brush hair.
本発明に係る装置は、 上記したノズルに係る発明の効果に加えて、 洗剤液など の副次媒体供給源に加圧手段を付加する必要がなくなり、 装置全体をコンパクト 化できる。  In the apparatus according to the present invention, in addition to the effects of the invention relating to the nozzle described above, it is not necessary to add a pressurizing means to a secondary medium supply source such as a detergent liquid, and the entire apparatus can be made compact.
また、 噴出ノズルへの供給管路を気体供給管路のみとすることができるので、 噴出ノズルの操作を楽に行うことができる。  In addition, since the supply pipe to the ejection nozzle can be only the gas supply pipe, the operation of the ejection nozzle can be easily performed.
更に、 副次媒体の供給源を貯溜容器にすることができるので、 副次媒体の交換 を容易に行うことができる。  Further, since the supply source of the secondary medium can be a storage container, the secondary medium can be easily exchanged.
