Description

【０００１】
【発明の属する技術分野】
本発明は、本体ケースが折り畳み可能な携行用の小型電気機器、例えばイオン発生装置を内蔵している携行用のヘアーブラシに関する。
【０００２】
【従来の技術】
ヘアーブラシにおいて、ブラシ本体の内部にイオン発生装置と送風ファンとを設けることは公知である（例えば特許文献１参照）。そこでは、オゾンまたはイオンを発生する放電電極や、放電電流を調整するための電源回路、および送風ファンなどが、中空のブラシ本体の内部に収容されている。本発明に関して、ケースの姿勢変更動作を利用してスイッチを切り換えることは公知である（特許文献２参照）。そこでは、ドライヤ本体が壁面に固定した基部で上下揺動可能に支持してあり、揺動中心となるヒンジ部の近傍にドライヤ本体の姿勢変化を検知するスイッチが配されている。

【発明が解決しようとする課題】
本発明においては、本体ケースが折り畳み自在に連結される第１ケースと第２ケースとで構成され、小型電気機器をコンパクトに折り畳んだ状態で携行できるようにする。このような折り畳み可能な小型電気機器においては、電池の無駄な消費を避けるためにも、本体ケース内に収容した電装品が携行時に駆動されるのを確実に阻止する必要がある。例えば、本体ケースを折り畳んだ状態において、スイッチボタンやスイッチノブが折り畳まれたケースの対向面に臨むように配置すると、携行時に電源スイッチがオン状態に切り換わるのを避けることができる。
【０００５】
しかし万全とは言いがたく、例えば文房具や身装品などの小物がスイッチボタンとケースとの対向隙間に入り込んだり、折り畳んだ筈の本体ケースが徐々に拡開して、電源スイッチがオン状態に切り換わるおそれがある。このように、電源スイッチが誤ってオン状態になると、小型電気機器これ自体、あるいは小型電気機器を携行するバッグや鞄をいためてしまうおそれがある。とくに、本体ケースの内部に発熱機器が組み込まれている場合には、熱がこもるため危険である。
【０００６】
本発明の目的は、本体ケースが折り畳み自在に構成された小型電気機器において、携行時に電源スイッチがオン状態に切り換わるのを確実に防止し、以て電池の無駄な消耗を阻止し、さらに本体ケース内の電装品が駆動されることに基づく種々の不具合を解消することにある。本発明の目的は、コンパクトに折り畳める携行用のへアーブラシ、中でもイオン発生機能を備えた携行用のへアーブラシを提供することにある。
【０００７】
【課題を解決するための手段】
本発明は、本体ケース１と、本体ケース１の内部に組み込まれるイオン発生装置を含む電装品と、電装品用の通電路をオン状態とオフ状態とに切り換える電源スイッチ１０とを含むイオン発生機能を備えた小型電気機器である。本体ケース１は、第１ケース３と第２ケース４の端部どうしを連結軸５で連結して、両ケース３・４が折り畳まれる不使用姿勢と、両ケース３・４が全開される使用姿勢とに姿勢変更できるよう構成する。電源スイッチ１０は、第１ケース３と第２ケース４との開閉動作に連動して、オン状態とオフ状態とに切り換わるように構成し、第１ケース３と第２ケース４が使用姿勢に拡開操作された状態においてのみ、電源スイッチ１０がオン状態に切り換わるように構成する。
【０００８】
第１ケース３と第２ケース４とは、左右に隣接する連結ボス１９・２５と、連結ボス１９・２５どうしを連結する連結軸５とを介して相対回動自在に連結する。そして、片方の連結ボス２５の近傍に電源スイッチ１０を配置し、他方の連結ボス１９で電源スイッチ１０を切り換え操作できるようにする。
電源スイッチ１０は、スイッチ端子５１を接離操作する切換えピース５３と、切換えピース５３を移動付勢するばね５４とを含む。連結ボス１９に電源スイッチ１０を切り換え操作する操作体６０を設ける。操作体６０を、切換えピース５３の接当腕５７をばね５４に抗してオフ状態に維持する受壁６１と、接当腕５７を落ち込み係合させてオン状態に維持する凹部６２とで構成する。そして、凹部６２を、折り畳み状態において、接当腕５７の先端から１８０度位相のずれた位置に設け、第１ケース３と第２ケース４とが全開される使用姿勢の状態においてのみ、接当腕５７の先端が凹部６２に落ち込み、電源スイッチ１０がオン状態に切り換わるようにする。
【０００９】
電源スイッチ１０は、第１ケース３と第２ケース４とのいずれか一方のケース内部に、外部から切り換え操作不能に収容されている。
【００１０】
第１ケース３と第２ケース４との間には、不使用姿勢と使用姿勢とにおいて、それぞれ両ケース３・４の開閉を規制する節動機構を設ける。
【００１１】
電源スイッチ１０は、一対のスイッチ端子５１・５１と、一方のスイッチ端子５１を他方のスイッチ端子５１に接離操作する切換えピース５３と、切換えピース５３を移動付勢するばね５４と、これらのスイッチ部品を支持するスイッチベース５５とでユニット部品化する。
【００１２】
一対の連結ボス１９・２５の片方２５に連結軸５を固定し、他方の連結ボス１９を連結軸５に相対回動可能に連結する。節動機構は、連結軸５に固定される第２節動板４１と、他方の連結ボス１９に固定されて第２節動板４１に対して相対回動する第１節動板４０とで構成する。両節動板４０・４１の摺動面には、互いに凹凸係合する係合突起４４と係合凹部４３とを設けて、不使用姿勢と使用姿勢とにおいて、第１ケース３と第２ケース４を開閉規制できるようにする。
【００１３】
第１節動板４０と第２節動板４１とは、それぞれ円板状に形成して板面どうしが摺動できるように密着接合されており、両節動板４０・４１の周縁に、互いに凹凸係合する係合突起４４と係合凹部４３とを設けることができる。
【００１４】
第１ケース３と第２ケース４とは、それぞれ側面視において半円状に形成し、折り畳み状態において第２ケース４と対向する第１ケース３の平坦壁にブラシユニット２を装着する。第１ケース３の内部には、マイナスイオンを生成する放電体１２およびトランス１１と、マイナスイオンをケース外へ送出する送風ファン１３と、送風ファン１３を回転駆動するモーター１４とを配置する。第２ケースの内部には、電池８および回路基板９を配置する。
【００１５】
【発明の作用効果】
本発明では、本体ケース１が、連結軸５を介して折り畳み開閉自在に連結された第１ケース３と第２ケース４とで構成されており、その内部に電装品用の通電路をオン状態とオフ状態とに切り換える電源スイッチ１０が設けてある小型電気機器において、電源スイッチ１０は、第１ケース３と第２ケース４の開閉動作に連動して、オン状態とオフ状態とに切り換わるようにした。そのうえで、第１ケース３と第２ケース４が使用姿勢に拡開操作された状態においてのみ、電源スイッチ１０がオン状態に切り換わるようにした。換言すると、本体ケース１が折り畳み姿勢から徐々に開放変位されることがあったとしても、第１ケース３と第２ケース４とが使用姿勢に拡開操作変位しない限りは、電源スイッチ１０がオン状態に切り換わるのを阻止できるので、小型電気機器を携行する際に本体ケース１内の電装品が駆動されるのを確実に防止して、電池８の無駄な消耗を防止できる。更に、電装品が駆動されることに基づく不具合、例えば本体ケースの内部に発熱機器が組み込んである場合には、小型電気機器を携行するバッグや鞄が熱を受けて変質したり、あるいは小型電気機器自体が過熱状態に陥って故障するのを確実に防止できる。
【００１６】
第１ケース３と第２ケース４とは、左右に隣接する連結ボス１９・２５と、連結ボス１９・２５どうしを連結する連結軸５とを介して相対回動自在に連結し、片方の連結ボス２５の近傍に電源スイッチ１０を配置し、他方の連結ボス１９で電源スイッチ１０を切り換え操作できるようにしてあると、両ケース３・４の開閉中心軸、すなわち連結軸５に近い位置で電源スイッチ１０をオン状態とオフ状態とに切り換えることができる。従って、例えば両ケース３・４の遊端寄りに電源スイッチ１０とその切換え具とを配置した場合に比べて、両ケース３・４を開閉する際の電源スイッチ１０と連結ボス１９との位置ずれが殆どないので、電源スイッチ１０のオンオフの切り換えが安定状態で確実に行え、長期使用時にも安定したスイッチ切り換えを行える。
【００１７】
第１ケース３と第２ケース４とのいずれか一方のケース内部に電源スイッチ１０を収容して、電源スイッチ１０が外部から切り換え操作されるのを防止する形態によれば、例えば文房具や身装品などの小物と一緒に小型電気機器をバッグや鞄に入れて携行するような場合に、小物類がスイッチボタンとケースとの対向隙間に入り込んだり、折り畳んだ筈の本体ケースが徐々に拡開されて電源スイッチがオン状態に切り換わるなど、使用者の意図とは無関係に電源スイッチ１０がオン状態に切り換わるのを確実に防止でき、小型電気機器を携行する際の安全性が向上する。
【００１８】
第１ケース３と第２ケース４との間に、不使用姿勢と使用姿勢とにおいて、それぞれ両ケース３・４の開閉を規制する節動機構を設けてあると、小型電気機器をバッグや鞄に入れて携行する際に、折り畳んだ状態の両ケース３・４が不用意に拡開したり、あるいは使用状態における両ケース３・４が屈曲変位したりするのを防止して、小型電気機器の使い勝手を向上できる。さらに、スイッチ端子５１を接離操作する切換えピース５３と、切換えピース５３を移動付勢するばね５４とを含んで電源スイッチ１０を構成し、連結ボス１９に電源スイッチ１０を切り換え操作する操作体６０を設けて、電源スイッチ１０が操作体６０でオン状態に切り換えられたとき、切換えピース５３の接当腕５７を凹部６２に落ち込み係合させるようにしたスイッチ構造によれば、先の節動機構による位置保持機能に加えて、切換えピース５３による位置保持作用を付加できるので、両ケース３・４を使用姿勢と不使用姿勢とのそれぞれの状態において、さらに確実に位置決め保持できる。
【００１９】
一対のスイッチ端子５１・５１と、一方のスイッチ端子５１を他方のスイッチ端子５１に接離操作する切換えピース５３と、切換えピース５３を移動付勢するばね５４と、これらのスイッチ部品を支持するスイッチベース５５とで電源スイッチ１０がユニット部品化されていると、電源スイッチ１０を１個のユニット部品として取り扱えるので、その本体ケース１に対する組み立てをより少ない手間で簡単に行え、電源スイッチ１０の切り換わりタイミングのばらつきも小さくできる。
【００２０】
連結軸５に固定される第２節動板４１と、他方の連結ボス１９に固定されて第２節動板４１に相対回動する第１節動板４０とで節動機構を構成し、両節動板４０・４１の摺動面に、互いに凹凸係合する係合突起４４と係合凹部４３とを設けて、不使用姿勢と使用姿勢とにおいて、第１ケース３と第２ケース４とを開閉規制できるようにしてあると、節動機構の強度向上を実現しながら、節動機構の組み付けが簡便に行える。詳しくは、両連結ボス１９・２５の揺動中心軸に沿う方向へ第２節動板４１が弾性変形すること、つまり第２節動板４１が板厚方向へ弾性変形することで、係合突起４４と係合凹部４３とを係脱できるので、構造強度に優れた節動機構とすることができる。さらに、隣接する連結ボス１９・２５を連結軸５で連結した後、両節動板４０・４１を連結軸５と連結ボス１９とに組み付ければよいので、節動機構の組み付けが少ない手間で簡便に行える。
【００２１】
第１節動板４０と第２節動板４１とをそれぞれ円板状に形成して、両節動板４０・４１の周縁に係合突起４４と係合凹部４３とを設けた節動機構によれば、第２節動板４１の板面の全体が弾性変形することで、係合突起４４と係合凹部４３とを係脱できるので、第２節動板４１の占めるスペースが小さいにもかかわらず、弾性変形するときの内部応力を大きく設定できる。従って、係合突起４４と係合凹部４３との係合力がより強固なものとして、節動機構の位置保持力が向上し、両ケース３・４を使用姿勢と不使用姿勢とに確実に維持できる。両節動板４０・４２の占有スペースが小さい分だけ節動機構をコンパクトにまとめて、小型電気機器が大型化するのを解消できる利点もある。
【００２２】
第１ケース３と第２ケース４とをそれぞれ側面視において半円状に形成したうえで、第１ケース３の内部に、マイナスイオンを生成する放電体１２およびトランス１１と、マイナスイオンをケース外へ送出する送風ファン１３と、送風ファン１３を回転駆動するモーター１４とを配置し、第２ケース４の内部に、電池８および回路基板９を配置し、さらに折り畳み状態において第２ケース４と対向する第１ケース３の平坦壁にブラシユニット２を装着したヘアーブラシによれば、マイナスイオンを髪に吹き付けながら髪を梳くことができるので、水分を含むマイナスイオンを毛髪の内部深くまで浸透させて水分を補給できる。従って、髪の水分率を高めて、ブラッシング後の髪の状態がしっとりとしたものになる。
【００２３】
【実施例】
図１ないし図１２は本発明に係る携行用のヘアーブラシ（小型電気機器）の実施例を示す。図１および図３において、ヘアーブラシは折り畳み可能に構成した本体ケース１と、ブラシユニット２とを有し、本体ケース１の内部にイオン発生装置が組み込まれている。
【００２４】
本体ケース１は、側面視がそれぞれ半円状に形成された第１ケース３と第２ケース４とを連結軸５で連結して、折り畳み可能に構成してあり、第１・第２の両ケース３・４を円形に折り畳んだ図２の状態と、両ケース３・４をアラビア数字の３の字形に拡開した図１、図３の状態とに揺動開閉できる。ブラシユニット２は、第１ケース３における第２ケース４との対向面に装着してあり、両ケース３・４を拡開することにより髪を梳くことができる。このときの第２ケース４はグリップとして機能し、片手で掴むことができる。
【００２５】
図１３においてマイナスイオン発生装置は、電源となる２個の乾電池（電池）８、イオン発生回路が実装された回路基板９、電源スイッチ１０、トランス１１、放電体１２、送風ファン１３およびそのモーター１４と、中継基板１５とを含む。これらのうち乾電池８、回路基板９、電源スイッチ１０の三者は第２ケース４内に組み込まれており、残りの部品１１〜１５は第１ケース３内に組み込まれている。
【００２６】
図４において第１ケース３は、ブラシユニット２が装着される内ケース３Ａと、内ケース３Ａの開口側面を塞ぐケース蓋３Ｂと、内ケース３Ａおよびケース蓋３Ｂに外嵌装着される透明の外ケース３Ｃと、内外両ケース３Ａ・３Ｃの間に挟み込まれる３枚の装飾シートとで構成する。
【００２７】
内ケース３Ａは、一側面が開口する木の葉形のプラスチック成形品からなり、ケース内にトランス１１、放電体１２、送風ファン１３およびモーター１４などを収容した後、その開口側面がケース蓋３Ｂで塞がれる。内ケース３Ａの一端には連結ボス１９が一体成形してあり、送風ファン１３と対向する円弧状の周壁には吸風口２０が開口してある。ケース３Ａの平坦壁には、マイナスイオンを送出するための開口２１と、ブラシユニット２を装着するための４個の装着穴とが開口している。外ケース３Ｃは、内ケース３Ａより一回り大きい弦月状のケース体からなり、先の吸風口２０と対向する壁面に吸込口２２が開口している。ケース蓋３Ｂおよび外ケース３Ｃは、それぞれ内ケース３Ａに熱溶着して固定する。
【００２８】
図５および図６において第２ケース４は、内ケース４Ａと、内ケース４Ａの開口面を塞ぐケース蓋４Ｂと、内ケース４Ａおよびケース蓋４Ｂに外嵌装着される透明の外ケース４Ｃと、電池蓋２３と、内外ケース４Ａ・４Ｃの間に挟み込まれる３枚の装飾シートとで構成されている。
【００２９】
内ケース４Ａは、図５において一側面と上面とが開口する木の葉形のプラスチック成形品からなり、ケース内に乾電池８を収容する電池室２４が区画形成されており、ケース端部に連結ボス２５が一体成形してある。乾電池８は図５においてケース上面の開口２６から出し入れされる。この開口２６は電池蓋２３を長手方向へスライド操作することにより開閉できる。外ケース４Ｃは、内ケース４Ａより一回り大きい弦月状のケース体からなる。ケース蓋４Ｂおよび外ケース４Ｃは、それぞれ内ケース４Ａに熱溶着して固定される。
【００３０】
図４においてブラシユニット２は、短冊状のブラシベース３０と、一群のブリッスル３１とを一体に成形したプラスチック成形品からなる。ブラシベース３０は第１ケース３に遊端側からスライド装着されて、ケース単に装着したストッパー片３２で抜け外れ不能にロック保持される。ブラシベース３０の中央には、マイナスイオンを送出するための吹出口３３を設けてあり、装着面にはＬ字状に折れ曲がる４個の係合爪３４を設けてある。
【００３１】
先に説明したように、第１ケース３と第２ケース４とは、それぞれの連結ボス１９・２５どうしが相対回動可能に連結される。詳しくは、図７に示すように、それぞれの連結ボス１９・２５に設けた内ボス１９ａおよび外ボス２５ａを内外に嵌合し、さらに第２ケース４の連結ボス２５にインサート固定した真鍮製の連結軸５で、連結ボス１９の内面に設けた軸受穴３６を軸支し、連結軸５の軸端に第２節動板４１を装着してビス４６で締結固定することにより、連結ボス１９・２５どうしを相対回動自在に連結する。
【００３２】
上記の連結構造を設けることによって、第１ケース３と第２ケース４とは折り畳み開閉できるが、折り畳み状態（不使用姿勢）と拡開状態（使用姿勢）とをそれぞれ維持するために、第１・第２ケース３・４の連結部に節動機構が組み込まれている。図１１・１２において節動機構は、第１ケース３側の連結ボス１９内に回転不能に組まれる第１節動板４０と、第１節動板４０の外面に被さる状態で、連結軸５にビス４６で相対回転不能に固定される第２節動板４１とからなる。第２節動板４１は連結ボス１９・２５が左右に分離するのを防ぐ抜止体を兼ねる。
【００３３】
第１節動板４０は、ばね板材を素材とするリング状のプレス成形品からなり、周縁４箇所に回り止め用の脚片４２と係合凹部４３とを９０度間隔で交互に形成し、板面中央に連結軸５用の挿通穴４８を通設してある。脚片４２を連結ボス１９内の係合溝４７に差し込み係合することにより、第１節動板４０を連結ボス１９と一体化できる。第２節動板４１は第１節動板４０と同様のプレス成形品からなり、周縁の対向２箇所に先の係合凹部４３と係合する係合突起４４を設け、板面の２箇所に連結軸５の係合溝５ａと係合する脚片４５を折り曲げ形成してある。
【００３４】
第１節動板４０は第１ケース３と同行回転し、連結軸５および第２節動板４１は第２ケース４と同行回転できる。従って、第１ケース３と第２ケース４とを拡開または折り畳み操作すると、両節動板４０・４１は相対回転して、全拡開位置と全折り畳み位置とのそれぞれにおいて、一対ずつの係合突起４４と係合凹部４３とが係合して、第１ケース３と第２ケース４とを開閉規制できる。なお、全拡開位置と全折り畳み位置との開閉角度は１８０度であり、開閉途中状態における係合突起４４は、第２節動板４１が弾性変形することで第１節動板４０の板面に乗り上がっている。符号５０は、連結ボス１９・２５の側端開口を塞ぐキャップである。
【００３５】
上記のように構成した節動構造によれば、第２節動板４１が板厚方向へ弾性変形することで、係合突起４４と係合凹部４３とを係脱できるので、構造強度に優れた節動機構とすることができる。さらに、隣接する連結ボス１９・２５を連結軸５で連結した後、両節動板４０・４１を連結軸５と連結ボス１９とに組み付ければよいので、節動機構の組み付けを少ない手間で簡便に行える。また、本実施例の場合、節動機構を仮組みした状態で両節動板４０・４１の密着圧力をビス４６の締め具合で調整変更できるので、係合突起４４と係合凹部４３との係脱力の調整作業を、少ない手間で確実に行えることになる。
【００３６】
因みに、上記の節動構造では、ビス４６を締め付け過ぎた場合に、開閉動作をスムーズに行えなくなるおそれがある。このようなビス４６の締め付け過ぎを防ぐために、連結ボス１９と第１節動板４０との間に、連結軸５に挿通される波形ワッシャーを配設し、第１節動板４０を連結軸５の軸まわりには回転規制されるが、軸方向へは移動できるように支持し、そのうえで、第２節動板４１を連結ボス１９に対して、第２節動板４１が軸方向へ移動できない状態でビス４６によって固定する。こうした節動構造によれば、波形ワッシャーは第１節動板４０を一定圧力で押圧しており、第１節動板４０と第２節動板４１とは常に一定圧で摺接することになるので、ビス４６を締め付け過ぎても第２節動板４１が過度に第１節動板４０に密着することはなく、従って両ケース３・４の開閉動作を常に円滑に行える。
【００３７】
図６において電源スイッチ１０は、一対のスイッチ端子５１を支持する端子ブロック５２と、一方のスイッチ端子５１を他方のスイッチ端子５１に接離操作するための切換えピース５３と、切換えピース５３をスイッチ端子５１に向かって揺動付勢するキックばね５４とを含み、これらのスイッチ部品をスイッチベース５５に組み付けてユニット部品化してある。切換えピース５３は、スイッチ端子５１を押し付け操作する操作腕５６と、連結ボス１９に設けた操作体６０で受け止められる接当腕５７とを一体に備えており、両腕５６・５７の中途部が軸５８で揺動自在に軸支されている。
【００３８】
図９においてスイッチベース５５は、第２ケース４内の連結ボス２５の近傍に配置されて、切換えピース５３の接当腕５７が第１ケース３の連結ボス１９に臨んでいる。この組み付け状態において、接当腕５７の先端は、外ボス２５ａの切欠き部を介して内ボス１９ａの周面で受け止められている。操作体６０は内ボス１９ａの半周面を占める受壁６１と、内ボス１９ａの周面一箇所に設けた凹部６２とからなり、両ケース３・４が折り畳み状態から１８０度拡開操作された状態においてのみ、図９および図１０に示すように接当腕５７の先端が凹部６２に落ち込み係合でき、このとき先の節動板４０・４１の係合突起４４と係合凹部４３とが係合して、第１ケース３と第２ケース４の相対回動動作を規制している。この落ち込み動作に伴って、操作腕５６が片方のスイッチ端子５１を押圧して、他方のスイッチ端子５１に接触させる。互いに係合する接当腕５７と凹部６２とは、第１ケース３と第２ケース４とを使用姿勢に位置保持することにも役立っている。
【００３９】
電源スイッチ１０は、第１・第２ケース３・４の開閉動作に連動してオン状態とオフ状態とに切り換わり、両ケース３・４が折り畳まれている状態、若しくは開放途中においてはオフ状態になっており、両ケース３・４が完全に拡開操作された状態においてのみオン状態に切り換わる。そのために先の凹部６２は、図８に示すように、折り畳み状態において接当腕５７の先端から１８０度位相がずれた位置に設けてある。電源スイッチ１０は、第１ケース３と第２ケース４とのいずれか一方のケース内部に、外部から切り換え操作不能に収容されている。つまり、本実施例においては、ユニット化された電源スイッチ１０が第２ケース４内にあり、その構成部品であるスイッチ駆動用の接当腕５７も連結ボス２５の外ボス２５ａによって、第１・第２ケース３・４がどの開閉位置にあっても、外部に露呈していないよう支持されている。これにより、使用者の意図とは無関係に電源スイッチ１０がオン状態に切り換わるのを確実に防止でき、小型電気機器を携行する際の安全性が向上する。
【００４０】
図２において放電体１２は、プラスチック成形品からなる電極ホルダー６５と、電極ホルダー６５に装着される針状の中心電極６６およびリング状の周囲電極６７と、両電極６６・６７を隔離区分する絶縁筒６８とでユニット部品化してある。電極ホルダー６５は、四角形状のフランジ６９と、フランジ６９の両面に突設された電極筒７０とを一体に備えており、フランジ６９に通気口７１を設けてある。電極筒７０の中心に中心電極６６を固定し、その外側を絶縁筒６８で囲み、電極筒７０の周面に周囲電極６７を配置してある。
【００４１】
図１３において回路基板９には、昇圧回路と、整流回路７６と、パルス発生回路７７を構成する電子部品等が実装されている。昇圧回路は、前段の発振回路７８と後段の昇圧回路部（１次トランス）７９とからなり、乾電池８から供給される３Ｖの直流電流を前段の発振回路７８によってパルス化され、続けて後段の昇圧回路部によって１００Ｖ近くに昇圧変換される。昇圧変換されたパルスは、整流回路７６により整流され、サイダックやサイリスタ等で構成されるパルス発生回路７７によって高圧のパルスに変換される。このパルスは、第１ケース３内に収容したトランス（２次トランス）１１で４ｋＶに昇圧されて、放電体１２へ供給される。イオン発生装置が作動しているのを点灯表示するために、第２ケース４の連結ボス２５寄り部位に発光ダイオード８０が配置されている。
【００４２】
上記のように構成したイオン発生装置によれば、トランス１１で昇圧した高電圧のうち、ダイオードを通過したマイナス電圧のみが中心電極６６に印加され、中心電極６６から周囲電極６７へ向かって電子が放出されるので、両電極の周辺の空気中の酸素分子が、マイナスイオン化され、空気流とともに吹出口３３から放出される。水分を含むマイナスイオンは、毛髪の内部深くまで浸透して水分を補給でき、従って髪の水分率を高めることができる。頭部周辺に浮遊するマイナスイオンは、リラックス効果を高める作用も期待でき、イオン健康装置として利用することもできる。
【００４３】
図１４は電源スイッチ１０の変形例を示す。そこでは、切換えピース５３をスライド軸７４と操作腕５６とでＴ字状に形成し、スライド軸７４をスイッチベース５５でスライド自在に案内支持し、切換えピース５３の全体を圧縮コイル形のばね５４で連結ボス１９に向かってスライド付勢した。このように切換えピース５３は、スライド変位を利用してスイッチ端子５１をオン・オフいずれかに切り換えることができる。
【００４４】
上記の実施例以外に、本発明はヘアーブロッサー、ヘアードライヤー、バイブレーターを内蔵した頭皮マッサージャー、電動歯ブラシなどの小型電気機器にも適用できる。電池８としては充電池を適用できる。

[Problems to be solved by the invention]
In the present invention, the main body case is composed of a first case and a second case that are foldably connected so that a small electric device can be carried in a compactly folded state. In such a foldable small electric device, in order to avoid wasteful consumption of the battery, it is necessary to surely prevent the electrical component housed in the main body case from being driven when being carried. For example, when the switch case and the switch knob are arranged so as to face the opposite surface of the folded case when the main body case is folded, it is possible to prevent the power switch from being turned on during carrying.
[0005]
However, it is not perfect, for example, small items such as stationery and accessories enter the gap between the switch button and the case, or the main body case of the folded bag gradually expands, turning the power switch on There is a risk of switching. Thus, if the power switch is turned on by mistake, the small electric device itself or the bag or bag carrying the small electric device may be hurt. In particular, when a heat generating device is incorporated in the main body case, heat is trapped, which is dangerous.
[0006]
An object of the present invention is to reliably prevent the power switch from being turned on when carrying in a small electric device in which the main body case is configured to be foldable, thereby preventing wasteful consumption of the battery. The object is to eliminate various inconveniences caused by driving the electrical components in the case. An object of the present invention is to provide a portable hair brush that can be folded compactly, and in particular, a portable hair brush that has an ion generation function.

To do. The recessed portion 62 is provided at a position 180 degrees out of phase from the tip of the contact arm 57 in the folded state, and the contact is made only when the first case 3 and the second case 4 are fully opened. The tip of the arm 57 falls into the recess 62 so that the power switch 10 is turned on.
[0009]
The power switch 10 is housed in either one of the first case 3 and the second case 4 so that it cannot be switched from the outside.
[0010]
  Between the first case 3 and the second case 4, there is provided a moderation mechanism for restricting the opening and closing of both cases 3 and 4 in the non-use posture and the use posture, respectively..
[0011]

[0015]
[Effects of the invention]
In the present invention, the main body case 1 is composed of a first case 3 and a second case 4 which are connected to each other via a connecting shaft 5 so as to be foldable and openable. In the small electric device provided with the power switch 10 that switches between the first case 3 and the off state, the power switch 10 switches between the on state and the off state in conjunction with the opening / closing operation of the first case 3 and the second case 4. I made it. In addition, the power switch 10 is switched to the ON state only when the first case 3 and the second case 4 are expanded to the use posture. In other words, even if the main body case 1 is gradually disengaged from the folded posture, the power switch 10 is turned on as long as the first case 3 and the second case 4 are not displaced to the use posture. Since switching to the state can be prevented, it is possible to reliably prevent the electrical components in the main body case 1 from being driven when carrying a small electric device, and to prevent wasteful consumption of the battery 8. Furthermore, when a malfunction is caused by the driving of electrical components, for example, when a heat generating device is incorporated in the main body case, the bag or bag carrying the small electric device is affected by heat, or the small electric device is altered. It is possible to reliably prevent the device itself from being overheated and failing.
[0016]
The first case 3 and the second case 4 are connected to each other through a connecting boss 19/25 adjacent to the left and right and a connecting shaft 5 that connects the connecting bosses 19/25 so as to be rotatable relative to each other. If the power switch 10 is arranged in the vicinity of the boss 25 and the power switch 10 can be switched by the other connecting boss 19, the power is supplied at a position close to the opening / closing central axis of both cases 3, 4, that is, the connecting shaft 5. The switch 10 can be switched between an on state and an off state. Therefore, for example, as compared with the case where the power switch 10 and its switching tool are arranged near the free ends of both cases 3 and 4, the positional deviation between the power switch 10 and the connecting boss 19 when opening and closing both cases 3 and 4 is increased. Therefore, the power switch 10 can be reliably switched on and off in a stable state, and can be switched stably even during long-term use.
[0017]
According to the embodiment in which the power switch 10 is housed in one of the first case 3 and the second case 4 to prevent the power switch 10 from being switched from the outside, for example, a stationery or a clothing When carrying small electrical equipment in a bag or bag along with small items such as goods, small items may enter the gap between the switch button and the case, or the case body of the folded bag will gradually expand Thus, the power switch 10 can be reliably prevented from being turned on regardless of the user's intention, such as the power switch being turned on, and the safety when carrying a small electric device is improved.
[0018]
If a movement mechanism is provided between the first case 3 and the second case 4 to restrict the opening and closing of the cases 3 and 4 in the non-use posture and the use posture, the small electric device can be attached to a bag or bag. Small electric appliances that prevent both cases 3 and 4 in a folded state from being inadvertently expanded or both cases 3 and 4 in a used state from being bent and displaced when being carried in a container. Usability can be improved. Further, the power switch 10 is configured to include a switching piece 53 for operating the switch terminal 51 to be connected and separated and a spring 54 for moving and energizing the switching piece 53, and an operating body 60 for switching the power switch 10 to the connecting boss 19. According to the switch structure in which the contact arm 57 of the switching piece 53 falls into the recess 62 and engages when the power switch 10 is switched to the ON state by the operating body 60. In addition to the position holding function, the position holding action by the switching piece 53 can be added, so that the cases 3 and 4 can be more reliably positioned and held in each of the use posture and the non-use posture.
[0019]
A pair of switch terminals 51, 51, a switching piece 53 for operating one switch terminal 51 to and away from the other switch terminal 51, a spring 54 for moving and energizing the switching piece 53, and a switch for supporting these switch components When the power switch 10 is unitized with the base 55, the power switch 10 can be handled as a single unit part. Therefore, the assembly to the main body case 1 can be easily performed with less effort, and the power switch 10 can be switched. Timing variations can also be reduced.
[0020]
A second mechanism plate 41 fixed to the connection shaft 5 and a first mechanism plate 40 fixed to the other connection boss 19 and rotating relative to the second mechanism plate 41 constitute a mechanism. Engaging protrusions 44 and engaging recesses 43 that engage with each other are provided on the sliding surfaces of both the joint plates 40 and 41 so that the first case 3 and the second case 4 in the non-use posture and the use posture. If the opening and closing can be regulated, the assembling of the joint mechanism can be easily performed while improving the strength of the joint mechanism. Specifically, the second joint plate 41 is elastically deformed in the direction along the swing center axis of both the connecting bosses 19 and 25, that is, the second joint plate 41 is elastically deformed in the plate thickness direction, thereby being engaged. Since the projection 44 and the engaging recess 43 can be engaged and disengaged, a joint mechanism with excellent structural strength can be obtained. Furthermore, after connecting the adjacent connecting bosses 19 and 25 with the connecting shaft 5, both the jointing plates 40 and 41 may be assembled to the connecting shaft 5 and the connecting boss 19. It can be done easily.
[0021]
A joint mechanism in which the first joint plate 40 and the second joint plate 41 are each formed in a disc shape, and an engagement projection 44 and an engagement recess 43 are provided on the periphery of both joint plates 40 and 41. According to the above, since the entire plate surface of the second joint plate 41 is elastically deformed, the engagement protrusion 44 and the engagement recess 43 can be engaged and disengaged, so that the space occupied by the second joint plate 41 is small. However, the internal stress when elastically deforming can be set large. Accordingly, the engagement force between the engagement protrusion 44 and the engagement recess 43 is made stronger, the position holding force of the joint mechanism is improved, and both cases 3 and 4 are reliably maintained in the use posture and the non-use posture. it can. There is also an advantage that the size of the small-sized electric device can be eliminated by compactly collecting the small-sized movement mechanism as much as the space occupied by both the movement plates 40 and 42 is small.
[0022]
The first case 3 and the second case 4 are each formed in a semicircular shape when viewed from the side, and the discharge body 12 and the transformer 11 that generate negative ions are formed inside the first case 3, and the negative ions are removed from the case. The blower fan 13 that is sent to the motor and the motor 14 that rotationally drives the blower fan 13 are arranged, the battery 8 and the circuit board 9 are arranged inside the second case 4, and are opposed to the second case 4 in the folded state. According to the hair brush in which the brush unit 2 is mounted on the flat wall of the first case 3, it is possible to comb the hair while spraying negative ions on the hair. Can rehydrate.

[0031]
As described above, the first case 3 and the second case 4 are connected to each other so that the respective connecting bosses 19 and 25 are relatively rotatable. Specifically, as shown in FIG. 7, an inner boss 19 a and an outer boss 25 a provided on each of the connection bosses 19 and 25 are fitted inside and outside, and further, insert-fixed to the connection boss 25 of the second case 4. By connecting the bearing hole 36 provided on the inner surface of the connecting boss 19 with the connecting shaft 5, attaching the second joint plate 41 to the shaft end of the connecting shaft 5 and fastening and fixing with the screw 46, the connecting boss 19 -Connect the 25s together so that they can rotate relative to each other.
[0032]
Although the first case 3 and the second case 4 can be folded open and closed by providing the above connecting structure, the first case 3 and the second case 4 can be folded and opened in order to maintain the folded state (non-use posture) and the expanded state (use posture), respectively.・ A joint mechanism is incorporated in the connecting part of the second cases 3 and 4. In FIGS. 11 and 12, the joint mechanism is configured such that the joint shaft 5 is covered with the first joint plate 40 that is non-rotatably assembled in the joint boss 19 on the first case 3 side and the outer surface of the first joint plate 40. And a second articulation plate 41 fixed to be relatively non-rotatable by a screw 46. The second articulation plate 41 also serves as a retaining member that prevents the connecting bosses 19 and 25 from separating to the left and right.
[0033]
The first joint plate 40 is made of a ring-shaped press-molded product made of a spring plate material, and the leg pieces 42 for locking and the engaging recesses 43 are alternately formed at 90 ° intervals at the four peripheral edges. An insertion hole 48 for the connecting shaft 5 is provided in the center of the plate surface. The first joint plate 40 can be integrated with the connection boss 19 by inserting the leg piece 42 into the engagement groove 47 in the connection boss 19 and engaging with it. The second joint plate 41 is made of a press-molded product similar to the first joint plate 40, and is provided with two engagement projections 44 that engage with the previous engagement recesses 43 at two opposite positions on the periphery, and two places on the plate surface. A leg piece 45 that is engaged with the engaging groove 5a of the connecting shaft 5 is bent.
[0034]
The first joint plate 40 rotates along with the first case 3, and the connecting shaft 5 and the second joint plate 41 can rotate along with the second case 4. Therefore, when the first case 3 and the second case 4 are expanded or folded, both the articulation plates 40 and 41 rotate relative to each other at the fully expanded position and the fully folded position. The mating protrusion 44 and the engaging recess 43 are engaged, so that the opening and closing of the first case 3 and the second case 4 can be restricted. The opening / closing angle between the fully expanded position and the fully folded position is 180 degrees, and the engaging protrusion 44 in the middle of opening / closing is the plate of the first joint plate 40 as the second joint plate 41 is elastically deformed. I'm on the surface. Reference numeral 50 denotes a cap that closes the side end openings of the connecting bosses 19 and 25.
[0035]
According to the joint structure constructed as described above, the second joint plate 41 is elastically deformed in the thickness direction, so that the engagement protrusion 44 and the engagement recess 43 can be engaged and disengaged, so that the structure strength is excellent. It can be a moderation mechanism. Further, after connecting the adjacent connecting bosses 19 and 25 with the connecting shaft 5, both the jointing plates 40 and 41 may be assembled to the connecting shaft 5 and the connecting boss 19, so that the assembly of the jointing mechanism can be done with less effort. It can be done easily. In the case of the present embodiment, the contact pressure between both the movement plates 40 and 41 can be adjusted and changed by the tightening of the screws 46 in a state where the movement mechanism is temporarily assembled. The engagement / disengagement force can be adjusted reliably with little effort.
[0036]
Incidentally, in the above-described joint structure, when the screw 46 is tightened excessively, the opening / closing operation may not be performed smoothly. In order to prevent such overtightening of the screw 46, a corrugated washer inserted into the connecting shaft 5 is disposed between the connecting boss 19 and the first driving plate 40, and the first driving plate 40 is connected to the connecting shaft. Although the rotation is restricted around the axis of 5, it is supported so as to be movable in the axial direction, and then the second articulating plate 41 is moved in the axial direction with respect to the connecting boss 19. It is fixed with screws 46 in a state where it cannot. According to such a joint structure, the corrugated washer presses the first joint plate 40 with a constant pressure, and the first joint plate 40 and the second joint plate 41 are always in sliding contact with the constant pressure. Therefore, even if the screw 46 is tightened too much, the second joint plate 41 does not excessively adhere to the first joint plate 40, and therefore the opening and closing operations of both cases 3 and 4 can always be performed smoothly.
[0037]

Both cases 3 and 4 are expanded 180 degrees from the folded state. Only in the state, as shown in FIG. 9 and FIG. 10, the tip of the contact arm 57 falls into the recess 62 and can be engaged. At this time, the engagement protrusions 44 and the engagement recesses 43 of the previous joint plates 40 and 41 are formed. Engagement restricts the relative rotation of the first case 3 and the second case 4. Along with this depression operation, the operating arm 56 presses one switch terminal 51 to bring it into contact with the other switch terminal 51. The contact arm 57 and the recess 62 that engage with each other also serve to hold the first case 3 and the second case 4 in the use posture.
[0039]
The power switch 10 is switched between an on state and an off state in conjunction with the opening / closing operation of the first and second cases 3 and 4, and both the cases 3 and 4 are folded or in an off state during the opening. Therefore, the switch is turned on only when both cases 3 and 4 are fully expanded.
