Description

【０００１】
【発明の属する技術分野】
本発明は、美容などの目的のために体毛を脱毛するのに使用される脱毛装置に関するものである。
【０００２】
【従来の技術】
従来から、美容などの目的のために体毛を脱毛するのに使用される脱毛装置として、２つの脱毛手段を有するものが、国際特許公開ＷＯ９６／０４８１５号（従来例１）、特開昭５２−７２６７０号公報（従来例２）、特開平９−５６４４６号公報（従来例３）、米国特許第５０１１４８５号（従来例４）により知られている。
【０００３】
上記従来例のうち、従来例１には２つの脱毛手段の伝達駆動については明示されてない。
【０００４】
また、従来例２，従来例３のものは２つの脱毛手段が同一方向へ回転し、同一側面で伝達駆動をしている。
【０００５】
また、従来例４のものは２つの脱毛手段が反対方向へ回転し、同一側面で伝達駆動をしている。
【０００６】
しかして、上記従来例２乃至従来例４においては、いずれも、２つの脱毛手段の伝達駆動手段が、脱毛手段の一方の側面で行われており、このため、同一側面側のギアによる駆動音が大きくなるという問題がある。また、２つの脱毛手段の伝達駆動手段が、脱毛手段の一方の側面で行われているため、脱毛手段の肌面側で伝達ギア強度が必要で、ギア幅が厚くなり、脱毛手段の回転軸方向や回転軸と直交する幅方向が大きくなり、脱毛しようとする部位が見えにくくなったり、毛を狙いにくくなったり、使い勝手が悪いという問題がある。特に、腋等の凹部では肌面側の肌当て面が大きいと、肌への密着が悪く、抜き残しや短い毛が抜けず、脱毛効率が悪いという問題がある。
【０００７】
【発明が解決しようとする課題】
本発明は上記の点に鑑みてなされたものであり、伝達駆動音が少なく、脱毛部位が見やすく、毛が狙いやすく、使い勝手がよく、小型で、肌接触面の少ない腋等の凹部でも脱毛効率の良い脱毛装置を提供することを目的とするものである。
【０００８】
【課題を解決するための手段】
上記課題を解決するために、本発明に係る脱毛装置は、手で把持できる本体に毛を引き抜くための回転又は回動する脱毛手段を前後２つ平行に設けたものにおいて、一方の脱毛手段を回転又は回動するためのギア列よりなる伝達駆動手段をこの一方の脱毛手段の軸方向の一方の側面側に設け、他方の脱毛手段を回転又は回動するための伝達駆動手段をこの他方の脱毛手段の軸方向の他方の側面側に設け、前後２つの脱毛手段を互いに逆方向に回転又は回動させると共に、主ギアから脱毛手段への伝達において伝達駆動手段が一方の脱毛手段側と他方の脱毛手段側のギア段数が奇数個異なるように設けて成ることを特徴とするものである。このような構成とすることで、伝達駆動手段が両側面に位置して伝達駆動音が分散され、伝達駆動音が小さくなり、また，脱毛手段を回転又は回動駆動する負荷が小さくなって、ギア幅を薄くできて回転軸方向の肌当て面の長さを小さくでき、また、中央近くで伝達できるため回転軸方向と直交する側の幅を小さくでき、肌接触面を小さくできて使い勝手が良くなり、また、構造が簡単で組み立てやすく、しかも、前後２つの脱毛手段を互いに逆方向に回転又は回動させると共に、主ギアから脱毛手段への伝達において伝達駆動手段が一方の脱毛手段側と他方の脱毛手段側のギア段数が奇数個異なるように設けてあるので、脱毛手段のヘッドを小さくしたままで各脱毛手段の回転方向を逆にすることができて、腋等の毛の生え方向の異なる脱毛が容易にできる。
【００１１】
また、両側面に設けたギアの各回転中心が前後の脱毛手段の回転軸からずれた位置で且つ前後の脱毛手段の回転軸間に挟まれた領域に配置してあることが好ましい。このような構成とすることで、ギアを設けるにも係わらず回転軸と直交する方向の幅を小さくできることになる。
【００１４】
また、一方の脱毛手段に主ギアから当該脱毛手段の一方の側面側に配置した伝達駆動手段により駆動力が伝達されると共に、この一方の脱毛手段を介して他の脱毛手段の他方の側面側に配置した伝達駆動手段に駆動力を伝達して他方の脱毛手段を駆動することが好ましい。このような構成とすることで、簡単な構成で、両脱毛手段を両側の伝達駆動手段により駆動することができることになる。
【００１５】
また、２個の脱毛手段による肌接触面の回転軸方向の長さを回転軸に直交する幅方向の長さより小さくすることが好ましい。このような構成とすることで、腋等の凹部の肌への密着性が良くなる。
【００１６】
【発明の実施の形態】
以下、本発明の実施の形態を説明する。
【００１７】
脱毛装置は、図１乃至図５に示すようにモータ１１を内蔵する装置ケーシングを構成する本体１と、脱毛手段を内蔵する２つの脱毛ブロック２とから構成してある。本体１は、二つ割りのハウジング１０内に上記モータ１１、モータ１１の出力軸に取り付けたピニオン４と噛合するフェイスギア５、フェイスギア５に一体に設けられるギア５ａと噛合する中間ギア６、中間ギア６と噛合し一方の脱毛ブロック２を駆動させる駆動ギア７、中間ギア６と噛合した他方の脱毛ブロック２を駆動する駆動ギア８、９を内装し、また、ハウジング１０の下部に電源ジャック１４を固定した下カバー３を取り付け、更に、ハウジング１０にモータ１１をオン、オフするためのスイッチ１５を設けて構成してある。
【００１８】
脱毛ブロック２は図２、図６乃至図９に示すように、基台となる爪取付台２０に脱毛ブロック２の回転軸Ｊ４に平行に且つ円周に所定間隔で配置された３つの爪ブロック２１と、脱毛ブロック２を回転させるために駆動ギア７または駆動ギア９と噛合し爪取付台２０に連結される爪取付台ギア５０とからなるものとして形成してある。ここで、２つの脱毛ブロック２は本体１の上部の前後に回転軸Ｊ４が平行となるように配置されるものであるが、一方の脱毛ブロック２には軸方向の一方の片側に爪取付台ギア５０が設けられ、他方の脱毛ブロック２には軸方向の他方の片側に爪取付台ギア５０が設けられるものである。
【００１９】
脱毛ブロック２の駆動は以下のようにして行われる。すなわち、モータ１１の回転に伴い軸Ｊ１に取り付けられたフェイスギア５が回転すると、それに伴い軸Ｊ２に取り付けられている中間ギア６がギア５ａによって回転伝達されて、更に軸Ｊ３に取り付けられている駆動ギア８を介して駆動ギア９が一方の脱毛ブロック２の爪取付台２０に連結された爪取付台ギア５０を回転させる。他方の脱毛ブロック２は、爪取付台ギア５０が一方の脱毛ブロック２とは反対側に設けられていて、中間ギア６の回転駆動を駆動ギア８、９とは反対側に設けられた駆動ギア７に伝達し、他方の脱毛ブロック２を回転させている。このように一方の脱毛ブロック２の駆動手段を当該脱毛ブロック２の軸方向の一方の端部側に設け、これと平行な他方の脱毛ブロック２の駆動手段を当該脱毛ブロック２の軸方向の他方の端部側に設けることで（つまり駆動手段が両側に配置するように設けることで）、一方の側面に駆動音が集中することなく、両側面に分散されて、音の低い脱毛装置とすることができるものである。また、図１、図３、図４に示す実施形態のように伝達手段をギア列にすることで、組み立て性がよく、構造を簡略化できるものである。また、ギア段数を一方の脱毛ブロック２を回転させる方を偶数数段（駆動ギア７、８）、他方の脱毛ブロック２を回転させるギア段数を奇数段（駆動ギア９）にすることで、２つの脱毛ブロック２を互いに異なる方向に回転することができ、腋などの毛の生え方向の異なる部位をそれぞれの適した脱毛ブロック２で抜くことができるものである。また、この時、図４、図５に示すように両側面に設けた駆動ギア７、８、９の各回転中心がいずれも前後の脱毛ブロック２の回転軸Ｊ４からずれた位置で且つ前後の脱毛ブロック２の回転軸Ｊ４間に挟まれた領域に配置してあり、これにより、ギアを設けるにも係わらず回転軸Ｊ４と直交する方向の幅を小さくできることになる。また、この場合更に、駆動ギア７と駆動ギア８とが側面から見て重なる位置にあり、これにより、更にギアを設けるにも係わらず回転軸Ｊ４と直交する方向の幅を小さくできることになる。
【００２０】
駆動ギア８と駆動ギア９とは図４に示すように軸方向にずれた位置で側面側方向で重なるように配置したことによって、回転軸と直交する方向の脱毛手段のヘッドの幅を小さく小型化でき，脱毛部位を見やすくすることができるものである。
【００２１】
脱毛手段を構成する爪ブロック２１は、図１０に示すように、固定爪３０と爪支持部３１とを設けた爪支持部材３５と、可動爪３２と、可動爪３２を爪ブロック２１の回転軸方向に揺動させるための一対の開閉レバー３３、３４とで構成してある。
【００２２】
爪支持部材３５は中央部が開口した長方形状をした枠体部３５ｂの開口部分に枠体部３５ｂの長手方向に一定間隔を隔てて固定爪３０と爪支持部３１とを交互に配設すると共に固定爪３０と爪支持部３１との両端部をそれぞれ枠体部３５ｂに一体に形成してあり、また、枠体部３５ｂの長手方向の両端部の下面部にフック部３５ａが形成してある。ここで、固定爪３０は枠体部３５ｂの両側枠部３５ｃよりも上方に突出しており、更に、固定爪３０及び爪支持部３１の両端部は枠体部３５ｂの両側枠部３５ｃよりも内側に引き込んで位置している。
【００２３】
開閉レバー３３の前面には一定間隔でスリット溝３３ａが形成してあり、また、開閉レバー３３の一端部の一側面側からリブ３３ｂが設けてある。開閉レバー３４の前面には一定間隔でスリット溝３４ａが形成してあり、また、開閉レバー３４の他端部の他側面側からリブ３４ｂが設けてあり、一対の開閉レバー３３、３４を並べた状態で、リブ３３ｂが開閉レバー３４の他端部（突部３４ａを設けていない方の端部）と対向し、リブ３４ｂが開閉レバー３３の他端部（リブ３３ｂを設けていない方の端部）と対向させ、リブ３３ｂと開閉レバー３４の他端部との間乃至リブ３４ｂと開閉レバー３３の他端部との間にコイルスプリングのようなばね３６を介在させ、この状態で、一対の開閉レバー３３、３４のリブ３３ｂ、３４ｂをそれぞれ爪支持部材３５のフック部３５ａにスライド自在に嵌め込むことで、一対の開閉レバー３３を爪支持部材３５に組み込むものである。その後、可動爪３２の突部３２ａが前後で反対になるように、開閉レバー３３、３４のスリット溝３３ａ、３３ｂに嵌め込む。この時、嵌め込んだ状態で開閉レバー３３、３４はばね３６の付勢により互いに反対側に押されるが、可動爪３２の先端部の毛の挟持部が図１０に示すように、固定爪３０より離れるように爪支持部材３５に組み込まれるものである。ここで、可動爪３２は、固定爪３０と爪支持部３１に設けられた支点部３０ａ、３１ａを支点として揺動するものである。このように開閉手段と毛の把持部材が一つのブロック体として構成してある。このように構成することで、脱毛手段を小型化でき、腋等の毛が見えやすく、狙いやすくなるため、脱毛効率が良く、使い勝手のよいものとすることができる。
【００２４】
また、図１１には爪ブロック２１の構成の他の実施形態が示してある。この実施形態においては、開閉レバー３３、３４にそれぞれ複数個の可動爪３２を一体に形成したものである。開閉レバー３３の可動爪３２と、開閉レバー３４の可動爪３２とが互いに交互に位置するように、開閉レバー３３、３４を組み合わせ、一つのブロック体として構成している。このように構成することで、簡単な構造でブロック化でき、更に小型のヘッドにしても組み立て性が向上するものである。
【００２５】
爪取付台２０には回転軸Ｊ４と平行に且つ円周に所定間隔で複数の溝２０ａが設けてあり、この溝２０ａは回転軸Ｊ４と平行な方向の両端部のうちの一方と、爪取付台２０の外面とに開口しており、また爪取付台２０の半径方向において溝２０ａの外面側の開口縁部に支持部２０ｃが設けてある。溝２０には前述のようにしてブロック化した爪ブロック２１が軸方向の一端部の開口からスライドして嵌め込むことで組み込まれるものであり、この場合、溝２０内の幅広となった部分に枠体部３５ｂの側枠部３５ｃが嵌め込まれて支持部２０ｃが側枠部３５ｃの外面側に当たって爪ブロック２１が爪取付台２０の半径方向に支持され、回転軸Ｊ４と直交する方向への抜け止めがなされることになる。また、爪ブロック２１における毛の把持部材を構成するの固定爪３０と可動爪３２との先端部が溝２０ａの爪取付台２０の外面側の開口から外方に突出している。また、この状態で、図７に示すように、溝２０ａの爪取付台２０の外面側の開口端は爪支持部材３５の可動爪３２の揺動支点と一致させてある。
【００２６】
また、爪ブロック２１の長手方向（回転軸Ｊ４と平行な方向）の抜け止めは、一方は爪ブロック２１の端部の固定爪３０ｂの側面が爪取付台２０の一方の端部に設けた当たり部２０ｃに当ることによってなされ、また、他端部は爪取付台２０の側面に設けられた孔２０１に爪取付ギア５０に設けられたリブが圧入固定され、これにより爪ブロック２１の長手方向（回転軸Ｊ４と平行な方向）の抜け止めがなされる。このように両端部で爪ブロック２１の抜け止めをさせることで取り付け強度を向上させている。
【００２７】
爪取付台２０の周方向には複数のリブ２０ｂが形成してあり、この複数のリブ２０ｂは図１２、図１３に示すように、回転方向において、後方に位置する爪ブロック２１の固定爪３０と同一位置となっている。図１２において矢印イは回転方向を示し、図１３（ａ）は図１２のａ矢視図であり、図１３（ｂ）は図１２のｂ矢視図であり、図１３（ｃ）は図１２のｃ矢視図である。そして、この実施形態においては固定爪３０の位置が図１３に示すように互いにずれて位置するように構成してあり、このため、固定爪３０の後方に位置するリブ２０ｂとはずれたものとなっている。
【００２８】
また、２つの脱毛ブロック２間には肌押さえ部材５５が設けてある。肌押さえ部材５５は長手方向の両端部にリブ５５ａが突設してあり、ハウジング１０に設けた角孔１０１に嵌め込まれて固定してある。この肌押さえ部材５５は、その前後に位置する２つの脱毛ブロック２の上面よりも若干突出させてある。これは２つの脱毛ブロック２の上面よりも肌押さえ部材５５を若干突出させて肌に押さえつけることによって、脱毛ブロック２が互いに逆方向に回転していることにより、肌が互いに逆方向に引っ張られるときの刺激を防止しており、また、毛が同時に逆方向に脱毛されたり、また、どちらか一方の脱毛ブロック２によって脱毛されたときに毛と同時に肌が引っ張られるのを防止している。
【００２９】
脱毛ブロック２の回転における可動爪３２の揺動は、開閉レバー３３、３４の両端部に配置されるカム手段により行われる。カム手段は軸Ｊ５に対して回転自在にローラ４０を取り付けて構成してあり、爪取付台２０の回転軸Ｊ４がハウジング１０に取り付けられる孔１０ａの上方に設けた孔１０ｂに軸Ｊ５を固定し、ローラ４０を回転自在とするものである。そして、脱毛ブロック２が爪取付台ギア５０によって回転し、爪ブロック２１の一つが上方に回転してくると、当該開閉レバー３３、３４の端部がローラ４０によって押されて開閉レバー３３、３４が互いに内側に変位され、可動爪３２が爪支持部材３５に設けられた固定爪３０と爪支持部３１の支点部３０ａ、３０ｂを支点として固定爪３０を挟むようにして揺動され、これにより、固定爪３０と可動爪３２とで毛を挟持し、脱毛ブロック２が回転することで脱毛し、更に、脱毛ブロック２が回転することで、当該脱毛ブロック２の開閉レバー３３、３４からローラ４０から離れ、ばね３６の弾性力により開閉レバー３３、３４が互いに離れる方向に移動し、これにより脱毛した毛を離すものである。
【００３１】
次に、図１４に本発明の更に他の実施形態につき説明する。本実施形態においては、前後に平行に配置した２つの脱毛ブロック２のうち、一方の脱毛ブロック２の軸方向（長手方向）の両側にそれぞれ爪取付台ギア５０が設けてあり、他方の脱毛ブロック２には軸方向の他方の側面にのみ爪取付台ギア５０が設けてある。そして、図１４（ａ）に示すように、主ギアを構成する中間ギア６に噛合する駆動ギア７が、一方の脱毛ブロック２(つまり両側に爪取付台ギア５０を設けた方の脱毛ブロック２）の一方の爪取付台ギア５０に噛合し、図１４（ｂ）のように、該一方の脱毛ブロック２の他方の側面に設けた爪取付台ギア５０が駆動ギア８、９を介して他方の脱毛ブロック２の他方の側面に設けた爪取付台ギア５０に噛合している。したがって、本実施形態においては、モータ１１を回転すると、フェイスギア５が回転し、これにより主ギアを構成する中間ギア６が回転し、これにより、一方の爪取付台ギア５０の一方の側面側に配置した駆動ギア７を介して当該一方の爪取付台ギア５０が回転して一方の脱毛ブロック２が回転する。このように一方の脱毛ブロック２が回転すると、一方の脱毛ブロック２の他方の側面の爪取付台ギア５０の回転を他方の側面側に配置した駆動ギア８、９を介して他方の脱毛ブロック２の他方の側面に設けた爪取付台ギア５０に伝達し、これにより他方の脱毛ブロック２が回転する。このようにして回転を伝達することで、駆動音を両側に分散して小さくでき、また、駆動機構を小型化できるものである。
【００３２】
ところで、図１に示すように、２個の脱毛手段による肌接触面の回転軸方向の長さをＭとし、回転軸に直交する幅方向の長さをＮとした場合、脱毛手段による肌接触面の回転軸方向の長さＭを回転軸に直交する幅方向の長さＮより小さくすることで、腋のような窪みにも器具が動かし易く、また、肌密着が良くなり脱毛効率の良いものとすることができるものである。
【００３３】
【発明の効果】
上記のように本発明の請求項１記載の発明にあっては、手で把持できる本体に毛を引き抜くための回転又は回動する脱毛手段を前後２つ平行に設けたものにおいて、一方の脱毛手段を回転又は回動するためのギア列よりなる伝達駆動手段をこの一方の脱毛手段の軸方向の一方の側面側に設け、他方の脱毛手段を回転又は回動するための伝達駆動手段をこの他方の脱毛手段の軸方向の他方の側面側に設け、前後２つの脱毛手段を互いに逆方向に回転又は回動させると共に、主ギアから脱毛手段への伝達において伝達駆動手段が一方の脱毛手段側と他方の脱毛手段側のギア段数が奇数個異なるように設けてあるので、駆動伝達音が一方の側面側に集中せず、両側面に分散できて、音の低い脱毛装置を提供できるものであり、また、脱毛ヘッドを小型化できて、腋等の脱毛しようとする部位が見やすくなり、毛を狙って脱毛することが容易となって、使いやすく、腋等の凹部にも密着しやすくなり、切れ毛や、寝た毛の抜き残しがなく、脱毛効率が良くなり、更に、前後２つの脱毛手段を互いに逆方向に回転又は回動させると共に、主ギアから脱毛手段への伝達において伝達駆動手段を一方の脱毛手段側と他方の脱毛手段側のギア段数が奇数個異なるように設けてあるので、容易に２つの脱毛手段の回転方向を異方向に回転駆動することができるようになり、腋等の毛の生え方向の異なる部位をそれぞれ適した脱毛手段で抜くことができ、また、駆動手段がギア列であるため、組み立て性が良く、構造が簡略化できる。
【００３６】
また、請求項２記載の発明にあっては、上記請求項１記載の発明の効果に加えて、両側面に設けたギアの各回転中心が前後の脱毛手段の回転軸からずれた位置で且つ前後の脱毛手段の回転軸間に挟まれた領域に配置してあるので、両側にギアを設けたにもかかわらず、前後方向の幅を短くでき、これにより小型化できて、脱毛しようとする部位が見やすく、毛の狙いも良く、腋等での使い勝手が良いものである。
【００３９】
また、請求項３記載の発明にあっては、上記請求項１記載の発明の効果に加えて、一方の脱毛手段に主ギアから当該脱毛手段の一方の側面側に配置した伝達駆動手段により駆動力が伝達されると共に、この一方の脱毛手段を介して他の脱毛手段の他方の側面側に配置した伝達駆動手段に駆動力を伝達して他方の脱毛手段を駆動するので、駆動音を低くでき、また、脱毛ヘッドを小型化できて使い勝手が良くなるものである。
【００４０】
また、請求項４記載の発明にあっては、上記請求項１記載の発明の効果に加えて、２個の脱毛手段による肌接触面の回転軸方向の長さを回転軸に直交する幅方向の長さより小さくするので、腋等の凹部への肌密着が良くなり、毛切れや抜き残しがなく、脱毛効率が良くなるものであり、また、脱毛しようとする部位が見やすいものである。

BACKGROUND OF THE INVENTION
The present invention relates to a hair removal device used for hair removal for cosmetic purposes.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, as a hair removal device used for hair removal for purposes such as beauty, one having two hair removal means is International Patent Publication WO 96/04815 (Conventional Example 1), Japanese Patent Laid-Open No. 52-52. No. 72670 (conventional example 2), JP-A-9-56446 (conventional example 3), and US Pat. No. 5,011,485 (conventional example 4).
[0003]
Among the above conventional examples, the conventional example 1 does not clearly indicate the transmission drive of the two hair removal means.
[0004]
In the conventional examples 2 and 3, the two hair removal means rotate in the same direction and are driven to transmit on the same side.
[0005]
In the case of Conventional Example 4, the two hair removal means rotate in opposite directions and are driven to transmit on the same side.
[0006]
Therefore, in both of the above-described conventional examples 2 to 4, the transmission drive means of the two hair removal means is performed on one side surface of the hair removal means. There is a problem that becomes larger. Further, since the transmission drive means of the two epilation means are performed on one side of the epilation means, the transmission gear strength is required on the skin side of the epilation means, the gear width is increased, and the rotational shaft of the epilation means is increased. There is a problem that the width direction perpendicular to the direction and the rotation axis becomes large, and it is difficult to see the part to be depilated, it is difficult to aim at the hair, and the usability is poor. In particular, when the skin contact surface on the skin surface side is large in a concave portion such as a wrinkle, there is a problem that adhesion to the skin is poor, unremoved portions and short hair cannot be removed, and hair removal efficiency is poor.
[0007]
[Problems to be solved by the invention]
The present invention has been made in view of the above points, and has low transmission drive sound, easy to see the hair removal site, easy to aim at the hair, easy to use, small in size, and has a hair removal efficiency even in a concave portion such as a heel with a small skin contact surface. An object of the present invention is to provide a hair removal apparatus with good quality.
[0008]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, a hair removal apparatus according to the present invention is provided with a body that can be gripped by a hand and provided with two rotating front and rear hair removal means for pulling out hairs in parallel. A transmission drive means comprising a gear train for rotating or rotating is provided on one side surface in the axial direction of the one hair removal means, and a transmission drive means for rotating or rotating the other hair removal means. It is provided on the other side surface in the axial direction of the hair removal means, and the two front and rear hair removal means are rotated or rotated in opposite directions to each other, and the transmission drive means is connected to one hair removal means side and the other in transmission from the main gear to the hair removal means. The hair removal means is provided such that the number of gears on the hair removal means side is different by an odd number . With such a configuration, the transmission drive means is located on both sides and the transmission drive sound is dispersed, the transmission drive sound is reduced, and the load for rotating or rotating the epilation means is reduced, The gear width can be reduced, the length of the skin contact surface in the direction of the rotation axis can be reduced, and since the transmission can be made near the center, the width on the side perpendicular to the rotation axis direction can be reduced, and the skin contact surface can be reduced for ease of use. In addition, the structure is simple and easy to assemble, and the front and rear two epilation means are rotated or rotated in opposite directions, and the transmission drive means is connected to one epilation means side in transmission from the main gear to the epilation means. Since the number of gear steps on the other hair removal means side is different, the rotation direction of each hair removal means can be reversed while keeping the head of the hair removal means small, and the direction of hair growth such as wrinkles Different prolapse It can be easily.
[0011]
Moreover, it is preferable to arrange | position in the area | region pinched | interposed between the rotating shafts of the front and back depilation means in the position where each rotation center of the gear provided in both sides shifted from the rotating shaft of the front and back depilation means. With such a configuration, the width in the direction orthogonal to the rotation axis can be reduced despite the provision of gears.
[0014]
Further, the driving force is transmitted from the main gear to the one hair removal means by the transmission drive means arranged on one side surface of the hair removal means, and the other side surface side of the other hair removal means is transmitted through the one hair removal means. It is preferable to drive the other epilation means by transmitting a driving force to the transmission driving means arranged on the other side. By setting it as such a structure, both epilation means can be driven with the transmission drive means of both sides by simple structure.
[0015]
Moreover, it is preferable to make the length of the skin contact surface by the two hair removal means in the direction of the rotation axis smaller than the length in the width direction orthogonal to the rotation axis. By setting it as such a structure, the adhesiveness to the skin of recessed parts, such as a wrinkle, improves.
[0016]
DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below.
[0017]
As shown in FIGS. 1 to 5, the epilation device is composed of a main body 1 constituting an apparatus casing incorporating a motor 11 and two epilation blocks 2 incorporating epilation means. The main body 1 is divided into a housing 10 divided into two, the above-mentioned motor 11, a face gear 5 that meshes with a pinion 4 attached to the output shaft of the motor 11, an intermediate gear 6 that meshes with a gear 5 a that is provided integrally with the face gear 5, and an intermediate gear 6, drive gear 7 that drives one hair removal block 2 and drive gears 8 and 9 that drive the other hair removal block 2 that meshes with the intermediate gear 6, and a power jack 14 at the bottom of the housing 10. A fixed lower cover 3 is attached, and a switch 15 for turning the motor 11 on and off is provided on the housing 10.
