Description

【０００１】
【発明の属する技術分野】
本発明は、電動機により回転ブラシを回転駆動させる構成を有した電気掃除機用吸込具並びにこの電気掃除機用吸込具を接続する電気掃除機に関するものである。
【０００２】
【従来の技術】
従来、この種の電気掃除機用吸込具は、特開平８−３３２１６５にあるようなものであり、図１１から図１３に示すように構成していた。以下、その構成について説明する。
【０００３】
下面に吸込口５１を有する吸込具本体５２と、吸込口５１に臨ませて吸込具本体５２に回転自在に支持された回転ブラシ５３と、吸込具本体５２に内蔵され、回転ブラシ５３を回転駆動させるモータ５４と、吸込具本体５２に設けられ、吸込具本体５２の上下反転時モータ５４を停止させる駆動停止装置５５とを備え、駆動停止装置５５を、モータ５４をオン、オフ制御するスイッチ５６と、吸込具本体５２に支持され、吸込具本体５２から突出して被掃除面への設置状態を検出する検出部５７と、検出部５７の吸込具本体５２底面からの突出量に連動してスイッチ５６を操作する操作片５８と、吸込具本体５２の反転時に検出部５７の押圧を阻止する阻止部材５９とから構成し、検出部５７と操作片５８との間に阻止部材５９を配置した。
【０００４】
【発明が解決しようとする課題】
このような従来の構造では、吸込具本体５２を被掃除面に落下させたときに、タイミングにより阻止部材５９が、カバー６１と前記阻止部材５９の間に挿入した阻止補助体６０により一定以上回動できなくなり、スイッチ５６をオン状態になることを阻止するときがある。このとき、落下による衝撃を始めに受けた検出部５７から阻止部材５９に伝達される衝撃力はほとんど減衰することなく阻止部材５９に伝達され、阻止部材５９が破壊することがあった。そのため、阻止部材５９、検出部５７、操作片５８を形成する部材の強度を向上させるために大きな構成とする必要性や、耐衝撃力を向上させた高価な材料により形成する必要性があった。
【０００５】
本発明は上記従来の問題を解決するものであり、小型で安価な吸込具本体を提供することを目的としている。
【０００６】
【課題を解決するための手段】
本発明は上記目的を達成するために、下面に吸込口を有する吸込具本体と、前記吸込口に臨ませて吸込具本体に回転自在に支持された回転ブラシと、前記吸込具本体に内蔵され前記回転ブラシを回転駆動させる駆動源と、前記吸込具本体に内蔵され前記駆動源への通電をオン・オフする制御部と、前記制御部をオン・オフする操作部を備え、前記操作部は、前記吸込具本体に回動可能に軸支され、前記吸込具本体底面から突出して被掃除面への接地状態を検出する検出部と、前記検出部の前記吸込具本体底面からの突出量に連動して制御部を操作する操作片と、前記吸込口が略上方に向けられた時、前記制御部が阻止補助体を介してオン状態になることを阻止する阻止部材から構成され、前記阻止部材と前記検出部との間に前記操作片を配置し、前記検出部を吸込具本体内部に回動させたときに、前記検出部下面が前記吸込具本体底面部と同面もしくは前記吸込具本体側に位置するようにした電気掃除機用吸込具で、吸込具本体が被掃除面落下されたとき、タイミングにより阻止部材がスイッチをオン状態にする状態になったときの検出部からの衝撃を、検出部と阻止部材の間に操作片を介在させることで、操作片部で衝撃力を減衰させることで検出部、操作片、阻止部材の構成部品の強度を向上させるために、検出部から阻止部材までの構成を小型化できるとともに、安価な材料で構成できるために吸込具本体を小型、安価に形成できるものである。

【００１１】
【実施例】
以下、本発明の一実施例について、図１〜図１０を参照しながら説明する。
【００１２】
１は吸込具本体で、エラストマーやＰＶＣなどの軟体で形成して吸込具本体１が壁などに当たったときに衝撃を和らげ、壁面に傷つけを防止するバンパー２を、吸込具本体１の下面部を形成する下部枠体３と上面部を形成する上部枠体４に介在させて形成されている。吸込具本体１の後方略中央部には上部枠体４と下部枠体３とで回転自在に挟持されたパイプ５がある。
【００１３】
下部枠体３には、下面開口になる吸込口６があり、被掃除面上の塵埃はこの吸込口６から集塵される。また、上部枠体４と下部枠体３の間の空間を分断し、吸込口６を入り口に持つ吸込室７を形成する中部材８が設けられている。吸込室７には回転自在に保持され、吸込口６に臨むように設けられた回転ブラシ９が設けられ、回転ブラシ９はその回転軸中心に心材となる基体１０が構成され、基体１０の表面部には基体１０長手方向に伸びる溝部１１が形成され、溝部１１にはＰＶＣやエラストマーなどで形成されるブレードや毛ブラシなどで形成される塵埃掻上げ部１２が挿入されて構成されている。
【００１４】
回転ブラシ９の一端にはギア形状（図示せず）を形成されており、このギア形状（図示せず）と回転ブラシ９を回転駆動させる駆動源であるモータ１３とをベルト１４を張架させることで回転駆動力を伝達させている。また、モータ１３にはゴムなどの防振性のある材料にて形成されたサポート１５がモータ１３の前後に挿入されており、モータ１３を下部枠体３と上部枠体４でしっかりと保持している。
【００１５】
下部枠体３のモータ１３が収められている逆側の収納部分には、モータ１３の駆動を制御する制御部がある。制御部は駆動停止装置１６であり、吸込具本体１同様の効果が得られる。また、検出部１７には、被掃除面にスムーズに接触するようにローラー体２１が回転自在に保持されている。
【００１６】
吸込具本体１が被掃除面上に接触していることを検知する検出部１７と、検出部１７の回動軸を同一にもち、モータの供給電源をオン・オフ操作する操作片１８と吸込具本体１を裏返したときに検出部１７を誤って押されないよう検出部１７を固定する阻止部材１９からなる操作部２０（もしくはレバー体、以降操作部とする）が構成されている。操作部２０は、阻止部材１９、操作片１８、検出部１７の順で構成されている。なお、この順序が逆になっても同様の効果が得られる。また、検出部１７には、被掃除面にスムーズに接触するようにローラー体２１が回転自在に保持されている。
【００１７】
また検出部１７は、吸込具本体１の略中央部より設けるようにし、阻止部材１９が吸込具本体１の外側に向くように設けられている。
【００１８】
また操作部２０は、阻止部材１９から操作片１８までの距離Ｌ１よりも操作片１８から検出部２０までの距離Ｌ２が長くなるように構成されている。
【００１９】
操作部２０は、下部枠体３の下面に開口する穴部から検出部１７を突出させ、ローラー体２１により被掃除面を検出するが、その際に操作部２０は下部枠体３に回動自在に保持されている。検出部１７およびローラー体２１が下部枠体３の内側にもっとも入り込んだときに検出部１７およびローラー体２１の下面が下部枠体３の下面より同面もしくは０．５ｍｍから１ｍｍほど中に入り込むように設定されている。
【００２０】
吸込具本体１のモータ１３に電源を供給する供給部は電源線２２で、前記電源線２２はパイプ５内部に設けられている。電源線２２およびモータ１３からのリード線２３は、駆動停止装置１６に設けられ、モータ１３のオン・オフ制御および保護を制御する制御基盤２４に接続される。また、制御基盤２４には操作片１８にてオン・オフの操作をされるスイッチ部２５が設けられた制御部２６が一体に設けられている。制御部２６は、リミットスイッチなどの小型スイッチなどで構成されている。
【００２１】
また、制御部２６は、スイッチ部２５が下部枠体３の方を向くように設置されている。
【００２２】
操作部２０は下部枠体３に回動自在に保持されているが、その際に検出部１７および阻止部材１９は各々囲まれた閉鎖空間部である検出部部屋３０と阻止部材部屋３１が存在する。検出部１７、操作片１８と阻止部材１９を接続するのは、回動するための軸部２７であり、その軸部２７を下部枠体３と検出部１７の上面を覆う検出部部屋カバー２８と阻止部材部屋カバー２９とで挟持している。このときに検出部１７が回動できるように検出部部屋３０の内側壁と検出部１７の側面に隙間Ｌ３が設定されており、同様に阻止部材１９と阻止部材部屋３１との間にも隙間Ｌ４が設定されている。このとき、隙間Ｌ３は隙間Ｌ４よりも小さくなるよう設けてある。
【００２３】
また、検出部部屋３０と阻止部材部屋３１は一体化されており、カバー体３４を形成し、さらに検出部部屋３０の上面部には制御基盤２４が設置される。検出部部屋３０の上面部にはレール状のレール溝体３２があり、レール溝体３２は吸込具本体１前方方向から後方にかけて開口し、かつ被掃除面と略水平になるように設けられている。このレール溝体３２に制御基盤２４が挟み込まれて固定されるようになっている。また、阻止部材部屋３１側面には凸リブ３３が設けられ、この凸リブ３３に差し込まれて制御部２６が固定されるようになっている。
【００２４】
阻止部材部屋３１には阻止部材１９を、吸込具本体１が裏返しになったときに規制する阻止補助体３５が存在する。阻止補助体３５は阻止部材部屋３１に自由に移動できるように鉄球などの球形状をしている。また、阻止補助体３５は吸込具本体１が表向きに有るときには、下部枠体３に形成された一対の保持リブ３６に収まるように構成されている。このとき、阻止補助体３５は、保持リブ３６、下部枠体３と阻止部材１９に挟まれて存在するために安定して保持される。
【００２５】
また、阻止部材部屋３１内部には阻止補助体３５が天面方向に向かって移動する際に斜面を登るような構成になるように斜面部３７が設けられている。斜面部３７は、被掃除面に垂直な軸に対して１０°から３０°の傾斜を設けて構成されている。
【００２６】
カバー体３４と下部枠体３が接合する面は、各々凹と凸の形状である凹凸状リブ３８が組み合わさるように設けてあり、カバー体３４と下部枠体３が接触する全周に設けてある。
【００２７】
検出部１７、操作片１８、阻止部材１９と軸受２７で構成される操作部２０は、吸込具本体１を被掃除面から離した時点で下部枠体３下面から突出するようにネ３９（もしくは附勢体、以降バネとする）にて附勢されている。バネ３９は、阻止部材１９から吸込具本体１の外側を向くように設けた軸体である附勢体受け４０に取り付けられ、軸体の最外部端面には、バネ３９の内径より０．５ｍｍから０．８ｍｍほど大きい鍔形状４２が設けられ、バネ３９の片端にはくの字形状に折り曲げた爪状の係り部４３が設けられ、一方では附勢体受け４０側には係り部４３がかかる係り受け４４が設けられている。
【００２８】
吸込具本体１は、パイプ５を介して延長管４５、ホース４６、掃除機本体４７に接続される。ホース４６は、掃除機本体４７の前面部に設けた接続口４８と連通し、集塵室４９と連通される。掃除機本体４７の後方部には電動送風機５０が設置されている。
【００２９】
上記構成において動作を説明すると、掃除機本体４７に電源が通電されて運転を行うと電動送風機５０が動作して、吸引風を発生させる。吸引風は集塵室４９を介して、接続口４８、ホース４６、延長管４５を通過して、パイプ５より吸込具本体１まで生じる。
【００３０】
吸込具本体１では、掃除機本体４７から電源が供給されるとパイプ５に内蔵された電源線２２から制御基盤２４を介してモータ１３に伝達される。電源を供給されたモータ１３は駆動を開始してベルト１４から回転ブラシ９を回転させる駆動力となる。被掃除面状の塵埃は、回転ブラシ９の周囲に設けられた塵埃掻上げ部１２により吸込具本体１に取り込まれ、掃除機本体４７で発生した吸引風により、吸込口６、吸込室７を通じて、パイプ５内部より集塵室４９に塵埃が集められる。
【００３１】
このとき吸込具本体１を空中に持ち上げたときにバネ４３で附勢された操作体２０は吸込具本体１下面より突出して、操作片１８を介してスイッチ部２５を操作して、制御部２６をオフ状態にしてモータ１３の供給電源を切り、モータ１３と回転ブラシ９の駆動を停止させる。
【００３２】
また、使用の仕方によっては吸込具本体１を被掃除面落下するときが有り、タイミングにより阻止部材１９と阻止部材部屋３１の間に阻止補助体３５が挟まり、検出部１７が吸込具本体１下面より突出したままになることがある。被掃除面からの衝撃は、検出部１７から伝達されて阻止部材１９まで伝達される。このとき、検出部１７と阻止部材１９の間に操作片１８が介在することで、操作片１８近傍で捩じれ力となって衝撃力が分散し、阻止部材１９に大きな応力を集中させなくてすむ。また、Ｌ１よりＬ２を長く取ることにより、衝撃力の分散をさらに大きくするため、操作体２０を構成する部分を小型化でき、かつ材料的にも高衝撃耐久性の材料でない一般材料にて形成することができる。また、このときに、阻止補助体３５が阻止部材１９と阻止部材部屋３１の間に移動して阻止部材１９を規制する頻度を低減させるため、阻止部材部屋３１に斜面部３７が設けられており、落下衝撃により跳ね上がってくる阻止補助体３５を斜面部３７に衝突させ、垂直の跳ね上がりから、斜め方向の上昇に変更させて、阻止部材１９と斜面部３７に挟持されるまえに落下させる運動にして、阻止部材１９を正常に動作させて、吸込具本体１が安定させて稼動できる。
【００３３】
吸込具本体１を被掃除面で使用している際に、凹凸の激しい被掃除面上であると吸込具本体１底面が被掃除面に対して平行を保つことが難しい。吸込具本体１底面部が被掃除面と接触することで検出部１７が出入りする頻度が多くなり、制御部２６がオン・オフを繰り返しやすくなるが、検出部１７を吸込具本体１の略中央近傍に設置することで、吸込具本体１を操作するための力が略中央近傍にパイプ５より伝達され、被掃除面上に吸込具本体１を押さえつける。そのため、検出部１７は被掃除面と常に接触できるために、吸込具本体１が被掃除面上にある限り誤動作を起こすことがない。
【００３４】
また、検出部１７のローラー体２１は、吸込具本体１の底面より内部に入り込むために、吸込具本体１が細かい段差を踏んだ際に、ローラー体２１が突出しているために、吸込具本体１が被掃除面に対して傾き、吸込具本体１の底面角部を被掃除面に接触させ、木床などの被掃除面に対して傷つけを行わないものである。
【００３５】
また、吸込具本体１を前後に操作しているときなどに、阻止補助体３５は阻止部材部屋３１で自由に動けるために、阻止部材部屋３１内部の壁に阻止補助体３５が当たり、カタカタと異音が発生していたのを、下部枠体３に阻止補助体３５を挟持するための保持リブ３６を設けることで防止することができる。
【００３６】
吸込具本体１はもっとも塵埃をかぶる部分であり、塵埃も内部に進入しやすい。特に操作体２０の可動部などはもっとも進入しやすい。これに対して、Ｌ３とＬ４の隙間の取り方を変えることで、検出部１７の回動軸部周辺のスラスト隙間を最小にして、外部からの塵埃進入からタイト性を向上させ、検出部１７を詰めた分の寸法ずれ（成形による収縮などによる公差分変動）を阻止部材１９での隙間Ｌ４により吸収して、操作体２０の回動性を損なわないようにできる。また、カバー体３４の底面部と下部枠体３のあわせ部に凹凸状リブ３８をほぼ全周に設けることで吸込具本体１の外部から内部に入り込む気流風を低減させ、細塵を内部に進入しがたい構成とできる。駆動停止装置１６でもっとも細塵に弱いところは制御部２６の可動接点部であるスイッチ部２５であり、これを被掃除面側に向けて設けることで細塵がスイッチ部２５に溜まらず、下を向けることで細塵を下方に落とすようになっているため、駆動停止装置１６の信頼性を高められる。
【００３７】
吸込具本体１が被掃除面に落下されたときに、制御基盤２４がレール溝体３２に挿入されているために制御基盤２４でもっとも割れやすい端面部を保持する構成が点接触から線接触に変更することで衝撃力を分散させて、制御基盤２４のパターンの剥離や割れを防ぐことができる。また、制御基盤２４、制御部２６、カバー体３４などに組み付けてあるために組み立て時に一つの部品を組み立てるだけでよく、安価で生産しやすくできる。
【００３８】
また、吸込具本体１が側方から落下されたときに附勢体３９が係り部４３に突っ張り、附勢体３９が外れることを防止できるために駆動停止装置１６が誤動作することを防ぐことができる。
【００３９】
【発明の効果】
以上のように本発明によれば、吸込具本体が被掃除面落下されたとき、タイミングにより阻止部材がスイッチをオン状態にする状態になったときの検出部からの衝撃を、検出部と阻止部材の間に操作片を介在させることで、操作片部で衝撃力を減衰させることで検出部、操作片、阻止部材の構成部品の強度を向上させるために、検出部から阻止部材までの構成を小型化できるとともに、安価な材料で構成できるために吸込具本体およびそれを用いた電気掃除機を提供できる。

The control unit 26 includes a small switch such as a limit switch.
[0021]
Further, the control unit 26 is installed so that the switch unit 25 faces the lower frame 3.
[0022]
The operation unit 20 is rotatably held by the lower frame 3, and at this time, the detection unit 17 and the blocking member 19 each include a detection unit chamber 30 and a blocking member chamber 31 that are enclosed space portions.

Further, a convex rib 33 is provided on the side surface of the blocking member chamber 31, and the control portion 26 is fixed by being inserted into the convex rib 33.
[0024]
In the blocking member chamber 31, there is a blocking auxiliary body 35 that regulates the blocking member 19 when the suction tool main body 1 is turned upside down. The blocking auxiliary body 35 has a spherical shape such as an iron ball so that it can freely move to the blocking member chamber 31. Further, the blocking assisting body 35 is configured to fit in a pair of holding ribs 36 formed on the lower frame 3 when the suction tool main body 1 is face up. At this time, the blocking auxiliary body 35 is sandwiched between the holding rib 36, the lower frame 3 and the blocking member 19, and thus is stably held.
[0025]
In addition, a slope portion 37 is provided in the prevention member chamber 31 so as to be configured to climb the slope when the prevention auxiliary body 35 moves toward the top surface. The slope portion 37 is configured with an inclination of 10 ° to 30 ° with respect to an axis perpendicular to the surface to be cleaned.
[0026]
The surface where the cover body 34 and the lower frame body 3 are joined is provided so that concave and convex ribs 38 each having a concave shape and a convex shape are combined, and provided on the entire circumference where the cover body 34 and the lower frame body 3 are in contact. It is.
[0027]
The operation unit 20 including the detection unit 17, the operation piece 18, the blocking member 19, and the bearing 27 is configured to protrude from the lower surface of the lower frame 3 when the suction tool body 1 is separated from the surface to be cleaned (or It is energized by an energizing body, hereinafter referred to as a spring). The spring 39 is attached to an urging body receiver 40 which is a shaft body provided so as to face the outside of the suction tool main body 1 from the blocking member 19. The outermost end surface of the shaft body is 0.5 mm from the inner diameter of the spring 39. A hook 42 having a size of about 0.8 mm is provided, and a claw-like engagement portion 43 bent in a U-shape is provided at one end of the spring 39, while the engagement portion 43 is provided on the biasing body receiver 40 side. Such a dependency 44 is provided.
[0028]
The suction tool main body 1 is connected to the extension pipe 45, the hose 46, and the cleaner main body 47 through the pipe 5. The hose 46 communicates with a connection port 48 provided on the front surface of the cleaner body 47 and communicates with a dust collection chamber 49. An electric blower 50 is installed in the rear part of the cleaner body 47.
[0029]
The operation in the above configuration will be described. When the power is supplied to the cleaner main body 47 and the operation is performed, the electric blower 50 operates to generate suction air. The suction air is generated from the pipe 5 to the suction tool body 1 through the connection port 48, the hose 46 and the extension pipe 45 through the dust collection chamber 49.
[0030]
In the suction tool main body 1, when power is supplied from the cleaner main body 47, it is transmitted to the motor 13 through the control board 24 from the power line 22 built in the pipe 5. The motor 13 to which the power is supplied starts driving and becomes a driving force for rotating the rotating brush 9 from the belt 14. The dust on the surface to be cleaned is taken into the suction tool main body 1 by the dust scraper 12 provided around the rotary brush 9, and passes through the suction port 6 and the suction chamber 7 by the suction air generated by the cleaner main body 47. The dust is collected in the dust collecting chamber 49 from the inside of the pipe 5.
[0031]
At this time, when the suction tool main body 1 is lifted into the air, the operating body 20 urged by the spring 43 protrudes from the lower surface of the suction tool main body 1, operates the switch portion 25 via the operation piece 18, and controls the control portion 26. Is turned off, the power supply to the motor 13 is turned off, and the drive of the motor 13 and the rotating brush 9 is stopped.
[0032]
Further, depending on how it is used, the suction tool main body 1 may be dropped on the surface to be cleaned. Depending on the timing, the blocking auxiliary body 35 is sandwiched between the blocking member 19 and the blocking member chamber 31, and the detection unit 17 is connected to the lower surface of the suction tool main body 1. It may remain more prominent. The impact from the surface to be cleaned is transmitted from the detection unit 17 and transmitted to the blocking member 19. At this time, since the operation piece 18 is interposed between the detection unit 17 and the blocking member 19, the impact force is dispersed in the vicinity of the operation piece 18, so that it is not necessary to concentrate a large stress on the blocking member 19. . Further, since the dispersion of the impact force is further increased by taking L2 longer than L1, the portion constituting the operating body 20 can be reduced in size and formed of a general material that is not a material with high impact durability. can do. At this time, in order to reduce the frequency with which the blocking auxiliary body 35 moves between the blocking member 19 and the blocking member chamber 31 and regulates the blocking member 19, the blocking member chamber 31 is provided with a slope portion 37. Then, the blocking auxiliary body 35 that jumps up due to a drop impact is caused to collide with the inclined surface portion 37, and is changed from vertical jumping up to an obliquely rising direction so as to drop before being held between the blocking member 19 and the inclined surface portion 37. Thus, the suction member body 1 can be operated stably by operating the blocking member 19 normally.
[0033]
When the suction tool main body 1 is used on the surface to be cleaned, it is difficult to keep the bottom surface of the suction tool main body 1 parallel to the surface to be cleaned if the surface is a highly uneven surface. When the bottom surface of the suction tool main body 1 comes into contact with the surface to be cleaned, the frequency of the detection unit 17 entering and exiting increases, and the control unit 26 can easily turn on and off. By installing in the vicinity, the force for operating the suction tool main body 1 is transmitted from the pipe 5 in the vicinity of the center and presses the suction tool main body 1 on the surface to be cleaned. Therefore, since the detection unit 17 can always come into contact with the surface to be cleaned, no malfunction occurs as long as the suction tool body 1 is on the surface to be cleaned.
[0034]
Further, since the roller body 21 of the detection unit 17 enters the inside from the bottom surface of the suction tool main body 1, the roller body 21 protrudes when the suction tool main body 1 steps on a fine step, so that the suction tool main body 1 1 is inclined with respect to the surface to be cleaned, the bottom corner of the suction tool main body 1 is brought into contact with the surface to be cleaned, and the surface to be cleaned such as a wooden floor is not damaged.
[0035]
Further, when the suction tool main body 1 is operated back and forth, the blocking auxiliary body 35 can freely move in the blocking member chamber 31, so that the blocking auxiliary body 35 hits the wall inside the blocking member chamber 31, and The occurrence of abnormal noise can be prevented by providing holding ribs 36 for holding the blocking auxiliary body 35 in the lower frame 3.
[0036]
The suction tool main body 1 is the most dusty part, and the dust easily enters the inside. In particular, the movable part of the operating body 20 is most likely to enter. On the other hand, by changing the clearance between L3 and L4, the thrust gap around the rotating shaft of the detection unit 17 is minimized, and the tightness is improved from the entrance of dust from the outside. The dimensional deviation (tolerance fluctuation due to shrinkage due to molding) is absorbed by the gap L4 in the blocking member 19 so that the rotation of the operating body 20 is not impaired. In addition, by providing concave and convex ribs 38 on the entire periphery of the bottom portion of the cover body 34 and the lower frame body 3, airflow entering the inside from the outside of the suction tool body 1 is reduced, and fine dust is brought inside. It can be configured to be difficult to enter. In the drive stop device 16, the weakest part to the fine dust is the switch part 25 which is a movable contact part of the control part 26, and the dust is not collected in the switch part 25 by providing the switch part 25 toward the surface to be cleaned. Since the fine dust is dropped downward by directing, the reliability of the drive stop device 16 can be improved.
[0037]
Since the control base 24 is inserted into the rail groove 32 when the suction tool main body 1 is dropped onto the surface to be cleaned, the configuration that holds the end face portion that is most likely to break in the control base 24 is changed from a point contact to a line contact. By changing the impact force, it is possible to disperse the impact force and prevent the pattern of the control board 24 from being peeled or cracked. Further, since it is assembled to the control base 24, the control unit 26, the cover body 34, etc., it is only necessary to assemble one part at the time of assembly, and it can be produced at low cost and easily.
[0038]
In addition, when the suction tool main body 1 is dropped from the side, the urging body 39 can be pushed against the engaging portion 43 and the urging body 39 can be prevented from coming off, so that the drive stop device 16 can be prevented from malfunctioning. it can.
[0039]
【The invention's effect】
As described above, according to the present invention, when the suction tool body is dropped on the surface to be cleaned, the detection unit and the detection unit block the impact from the detection unit when the blocking member is in a state of turning on the switch depending on the timing. In order to improve the strength of the components of the detection unit, the operation piece, and the blocking member by attenuating the impact force at the operation piece by interposing the operation piece between the members, the configuration from the detection unit to the blocking member Can be made small, and can be made of an inexpensive material, so that it is possible to provide a suction tool body and a vacuum cleaner using the suction tool body.
