Description

本考案は家庭用機器の技術分野に関し、特に掃除機用ブラシ構造及び掃除機に関する。 The present invention relates to the technical field of household appliances, and particularly to the brush structure for vacuum cleaners and vacuum cleaners.

従来の家庭用掃除機の動作原理は次のとおりである。モータが羽根を高速回転させ、密閉された掃除機のキャビティ内に空気負圧が発生してほこりを吸引する。掃除機は、通常、床に飛散したほこりやゴミしか吸引できず、花瓶や仏像などに付着したほこりやゴミを吸引することは困難である。この場合、花瓶や仏像などを動かしたくない場合は、掃除機の除塵管を軽くたたいて除塵する必要があるが、このような叩きにより花瓶や仏像などを壊すことがある。 The operating principle of a conventional household vacuum cleaner is as follows. The motor rotates the blades at high speed, and negative air pressure is generated in the cavity of the sealed vacuum cleaner to suck in dust. A vacuum cleaner can usually only suck dust and dirt scattered on the floor, and it is difficult to suck dust and dirt attached to vases and Buddha statues. In this case, if you do not want to move the vase or Buddha statue, you need to tap the dust removal tube of the vacuum cleaner to remove dust, but such tapping may damage the vase or Buddha statue.

これらの問題を解決するために、回転ダスターの構造が提案されている。たとえば、特許文献１に示すように、ダスターと掃除機の羽根は歯車機構を介して接続されており、掃除機が作動するときに、羽根は吸引力により回転しながら、ダスターを回転させ、それによりほこりをはたいて吸引する。 In order to solve these problems, a rotating duster structure has been proposed. For example, as shown in Patent Document 1, the duster and the blades of the vacuum cleaner are connected via a gear mechanism, and when the vacuum cleaner operates, the blades rotate by suction force to rotate the duster. Dust and suck.

しかしながら、従来の回転ダスター構造には、ダスターが高速で回転するときにダスターの毛が絡み合いやすく、回転速度を低下させると減速装置が複雑化するという問題がある。
以上に鑑み、本考案は、ほこりを容易にはたくことができるだけでなく、構造が簡単である掃除機用ブラシ構造を提供することを目的とする。さらに、本考案は、このような掃除機用ブラシ構造を備える掃除機を提供することを目的とする。 However, the conventional rotary duster structure has a problem that the duster hairs are easily entangled when the duster rotates at a high speed, and the reduction gear becomes complicated when the rotation speed is lowered.
In view of the above, it is an object of the present invention to provide a brush structure for a vacuum cleaner, which not only can easily beat dust but also has a simple structure. Furthermore, it is an object of the present invention to provide a vacuum cleaner having such a brush structure for a vacuum cleaner.

図１は掃除機用ブラシ構造１００の一実施形態の斜視図であり、図２は掃除機用ブラシ構造１００の上面図であり、図３は図２におけるＡ−Ａ部の断面図であり、図１〜図３に示すように、本考案の第１態様の実施形態に係る掃除機用ブラシ構造１００は、第１取り付け部材１１０、第２取り付け部材１２０及び回転部１４０を備える。その中でも、第２取り付け部材１２０は第１取り付け部材１１０により保持され（たとえば支持方式で保持され）、第２取り付け部材１２０の先端１２０ａが第１取り付け部材１１０に対してＸＹ平面において揺動可能であり、第２取り付け部材１２０の先端１２０ａには、ブラシヘッド１３０が取り付け可能で、後端１２０ｂには、長さがＺ方向へ延在している第１スロット１２１が設けられ、回転部１４０は、第２取り付け部材１２０の後方で保持され（たとえば、支持方式で保持され）、回転部１４０の先端１４０ａには、回転部１４０の回転軸心Ｌ１に対して偏心する連結部材１４１が設けられ、連結部材１４１は第１スロット１２１に挿入され、第１スロット１２１の長さＳ１は、連結部材１４１がＹＺ平面において回転部１４０の回転軸心Ｌ１回りに自在に回動することを可能にするように設定され、回転部１４０が回転駆動されると、連結部材１４１は第２取り付け部材１２０を揺動駆動する。 FIG. 1 is a perspective view of an embodiment of the brush structure 100 for a vacuum cleaner, FIG. 2 is a top view of the brush structure 100 for a vacuum cleaner, and FIG. 3 is a cross-sectional view of a portion AA in FIG. As shown in FIGS. 1 to 3, the vacuum cleaner brush structure 100 according to the first embodiment of the present invention includes a first mounting member 110, a second mounting member 120, and a rotating portion 140. Among them, the second mounting member 120 is held by the first mounting member 110 (for example, held by a support method), and the tip 120a of the second mounting member 120 can swing with respect to the first mounting member 110 in the XY plane. A brush head 130 can be attached to the tip 120a of the second attachment member 120, a first slot 121 having a length extending in the Z direction is provided at the rear end 120b, and the rotating portion 140 has a rotating portion 140. , A connecting member 141 that is held behind the second mounting member 120 (for example, held by a support method) and that is eccentric to the rotation axis L1 of the rotating portion 140 is provided at the tip 140a of the rotating portion 140. The connecting member 141 is inserted into the first slot 121, and the length S1 of the first slot 121 allows the connecting member 141 to freely rotate around the rotation axis L1 of the rotating portion 140 in the YZ plane. When the rotating portion 140 is rotationally driven, the connecting member 141 swings and drives the second mounting member 120.

本実施形態では、第２取り付け部材１２０は、回転部１４０の回転軸心Ｌ１に対して偏心する連結部材１４１によって、第１取り付け部材１１０に対して揺動するように駆動することで、第２取り付け部材１２０の先端１２０ａに取り付けられたブラシヘッド１３０を揺動させ、それにより、ほこりを容易にはたくことができるだけでなく、簡単な構造とすることができる。 In the present embodiment, the second mounting member 120 is driven by the connecting member 141 that is eccentric to the rotation axis L1 of the rotating portion 140 so as to swing with respect to the first mounting member 110. The brush head 130 attached to the tip 120a of the attachment member 120 is swung so that dust can be easily beaten and the structure can be simplified.

さらに、ブラシヘッド１３０を回転ではなく揺動させることによって、ほこりをはたくため、ブラシヘッド１３０のブラシは、高い揺動速度で絡み合うことはない。 Further, since the brush head 130 is oscillated rather than rotated to remove dust, the brushes of the brush head 130 do not get entangled at a high oscillating speed.

本実施形態では、回転部１４０がその回転軸心Ｌ１回りに回転するときに、連結部材１４１は、回転部１４０の回転軸心Ｌ１を中心として回動する。第１スロット１２１はＺ方向へ延在しており、且つ第１スロット１２１の長さは、連結部材１４１がＹＺ平面において回転部１４０の回転軸心Ｌ１回りに自在に回動することを可能にするように設定され、即ち、第１スロット１２１の長さはＺ方向における連結部材１４１の最上端からＺ方向における連結部材１４１の最下端までの距離より大きく、したがって、連結部材１４１は、回動するときに、Ｚ方向において第１スロット１２１により制限されることがない。さらに、連結部材１４１がＹＺ平面において回動するときに、連結部材１４１は、第１スロット１２１内を摺動し、第１取り付け部材１１０に対してＸＹ平面において揺動するように第２取り付け部材１２０を駆動する。 In the present embodiment, when the rotating portion 140 rotates around the rotation axis L1, the connecting member 141 rotates about the rotation axis L1 of the rotating portion 140. The first slot 121 extends in the Z direction, and the length of the first slot 121 allows the connecting member 141 to freely rotate around the rotation axis L1 of the rotating portion 140 in the YZ plane. That is, the length of the first slot 121 is larger than the distance from the uppermost end of the connecting member 141 in the Z direction to the lowermost end of the connecting member 141 in the Z direction, so that the connecting member 141 rotates. When doing so, it is not limited by the first slot 121 in the Z direction. Further, when the connecting member 141 rotates in the YZ plane, the connecting member 141 slides in the first slot 121 and swings with respect to the first mounting member 110 in the XY plane. Drive 120.

もちろん、回転部１４０は、軸方向がＸ方向において延びるように構成されており、即ち、回転部１４０の回転軸心Ｌ１はＸ方向に平行してもよい。 Of course, the rotating portion 140 is configured so that the axial direction extends in the X direction, that is, the rotation axis L1 of the rotating portion 140 may be parallel to the X direction.

なお、ＸＹ平面において第２取り付け部材１２０をよりバランスよく駆動し、ある方向へ過度に揺動しないようにするために、第２取り付け部材１２０は、ＸＹ平面の中央位置（たとえば、図２の位置、即ち、連結部材１４１が第１スロット１２１の最上端又は最下端に位置する場合）に到達するとき、回転部１４０と同軸であるように構成されてもよい。 In order to drive the second mounting member 120 in a more balanced manner on the XY plane and prevent it from swinging excessively in a certain direction, the second mounting member 120 is placed at the center position of the XY plane (for example, the position shown in FIG. 2). That is, when the connecting member 141 is located at the uppermost end or the lowermost end of the first slot 121), it may be configured to be coaxial with the rotating portion 140.

いくつかの実施形態では、回転部１４０の先端１４０ａは、軸状であり、連結部材１４１は、柱状、たとえば円柱状であり、回転部１４０の先端１４０ａの端面から回転部１４０の回転軸心Ｌ１の方向に突出する。連結部材１４１は、回転部１４０の先端１４０ａと一体成形して偏心軸構造となってもよく、たとえばピン軸などを回転部１４０の先端１４０ａの端面に挿入して偏心軸構造となってもよい。さらに、連結部材１４１の形状は、円錐状又はほかの形状であってもよい。 In some embodiments, the tip 140a of the rotating portion 140 is axial and the connecting member 141 is columnar, for example cylindrical, from the end face of the tip 140a of the rotating portion 140 to the rotation axis L1 of the rotating portion 140. Protrudes in the direction of. The connecting member 141 may be integrally molded with the tip 140a of the rotating portion 140 to form an eccentric shaft structure, or for example, a pin shaft or the like may be inserted into the end surface of the tip 140a of the rotating portion 140 to form an eccentric shaft structure. .. Further, the shape of the connecting member 141 may be conical or other shape.

いくつかの実施形態では、連結部材１４１が第２取り付け部材１２０をスムーズに駆動し、連結部材１４１の回動半径が大きすぎることにより連結部材１４１と第２取り付け部材１２０が引っかかることを防止するために、ブラシ構造１００が掃除機たとえば８００Ｗ〜１０００Ｗのパワーの掃除機に取り付けられた場合、回転部１４０の回転軸心Ｌ１に対する連結部材１４１の最外側Ｌ２から、回転部１４０の回転軸心Ｌ１までの距離Ｓ２は、好ましくは６ｍｍ以下、より好ましくは５ｍｍ以下、さらに好ましくは４ｍｍ以下である。具体的には、４ｍｍの場合、たとえば、回転部１４０の先端１４０ａの軸径は約１２ｍｍであり、連結部材１４１の軸径は約４ｍｍであり、連結部材１４１の最外側Ｌ２から回転部１４０の先端１４０ａの回転軸心Ｌ１までの距離は約４ｍｍである。また、連結部材１４１の回動半径が小さすぎて、第２取り付け部材１２０の揺動の度合いが小さすぎることによって、ブラシヘッド１３０を効果的に揺動できないことを回避するために、連結部材１４１の最外側Ｌ２から回転部１４０の回転軸心Ｌ１までの距離は、好ましくは２ｍｍ以上、より好ましくは３ｍｍ以上である。また、ブラシ構造１００がたとえば１０００Ｗ以上のパワーの掃除機に取り付けられた場合、連結部材１４１の最外側Ｌ２から回転部１４０の回転軸心Ｌ１までの距離Ｓ２は、６〜１２ｍｍに設定されてもよい。もちろん、連結部材１４１の最外側Ｌ２から回転部１４０の回転軸心Ｌ１までの距離はそれに限定されず、当業者によって必要に応じて設定され得る。 In some embodiments, the connecting member 141 smoothly drives the second mounting member 120 to prevent the connecting member 141 and the second mounting member 120 from being caught by the turning radius of the connecting member 141 being too large. When the brush structure 100 is attached to a vacuum cleaner having a power of 800 W to 1000 W, for example, from the outermost L2 of the connecting member 141 to the rotating axis L1 of the rotating portion 140 to the rotating axis L1 of the rotating portion 140. The distance S2 is preferably 6 mm or less, more preferably 5 mm or less, still more preferably 4 mm or less. Specifically, in the case of 4 mm, for example, the shaft diameter of the tip 140a of the rotating portion 140 is about 12 mm, the shaft diameter of the connecting member 141 is about 4 mm, and the outermost L2 of the connecting member 141 to the rotating portion 140 The distance of the tip 140a to the rotation axis L1 is about 4 mm. Further, in order to prevent the brush head 130 from being unable to swing effectively due to the rotation radius of the connecting member 141 being too small and the degree of swinging of the second mounting member 120 being too small, the connecting member 141 The distance from the outermost L2 of the rotating portion 140 to the rotation axis L1 of the rotating portion 140 is preferably 2 mm or more, more preferably 3 mm or more. Further, when the brush structure 100 is attached to a vacuum cleaner having a power of 1000 W or more, for example, the distance S2 from the outermost L2 of the connecting member 141 to the rotation axis L1 of the rotating portion 140 may be set to 6 to 12 mm. Good. Of course, the distance from the outermost L2 of the connecting member 141 to the rotation axis L1 of the rotating portion 140 is not limited to this, and may be set as necessary by those skilled in the art.

いくつかの実施形態では、連結部材１４１が第２取り付け部材１２０をよりスムーズに駆動できるように、第１スロット１２１は、長円孔状であり、第１スロット１２１のＹ方向における幅は連結部材１４１の軸径よりもわずかに大きく設定され、たとえば、連結部材１４１の軸径が４ｍｍである場合、第１スロット１２１のＹ方向における幅は４．２ｍｍに設定される。それによって、連結部材１４１の最外側Ｌ２が第１スロット１２１の深さ方向（Ｘ方向）と、ＸＹ平面において夾角をなしたときに、即ち、連結部材１４１がＺ方向の最上端及び最下端以外のほかの位置に回転したときに、第１スロット１２１と連結部材１４１の間の隙間を通じて、連結部材１４１が自在に回動することができ、それによって、連結部材１４１は第２取り付け部材１２０をよりスムーズに駆動できる。 In some embodiments, the first slot 121 is oval and the width of the first slot 121 in the Y direction is such that the connecting member 141 can drive the second mounting member 120 more smoothly. It is set slightly larger than the shaft diameter of 141. For example, when the shaft diameter of the connecting member 141 is 4 mm, the width of the first slot 121 in the Y direction is set to 4.2 mm. As a result, when the outermost L2 of the connecting member 141 has an angle with the depth direction (X direction) of the first slot 121 and the XY plane, that is, the connecting member 141 is other than the uppermost end and the lowermost end in the Z direction. When rotated to other positions, the connecting member 141 can freely rotate through the gap between the first slot 121 and the connecting member 141, whereby the connecting member 141 can rotate the second mounting member 120. It can be driven more smoothly.

いくつかの実施形態では、連結部材１４１が第２取り付け部材１２０をスムーズに駆動するとともに、連結部材１４１が第２取り付け部材１２０から抜けることを防止するために、第２取り付け部材１２０の後端１２０ｂには、径方向において貫通する第２スロット１２２が設けられ、第２スロット１２２と第１スロット１２１は連通しており、第２スロット１２２の長さは第１スロット１２１の長さＳ１以上である。具体的には、たとえば、第２取り付け部材１２０の後端１２０ｂの端面に近い第１スロット１２１の一側から、第２取り付け部材１２０の後端１２０ｂの端面までの距離Ｓ３は約２ｍｍであり、第２スロット１２２のＸ方向における幅は約２．５ｍｍに設定される。その場合、連結部材１４１は第１スロット１２１に挿入され、且つ第２スロット１２２まで延びており、そして、連結部材１４１は、第２取り付け部材１２０の後端１２０ｂの端面から離れた第２スロット１２２の一側に当接しない。それによって、連結部材１４１と第１スロット１２１の接触長さを減少させるとともに、第２取り付け部材１２０に挿入された連結部材１４１の部分の距離を十分に長くし、それにより、連結部材１４１が第２取り付け部材１２０をスムーズに駆動するとともに、連結部材１４１が第２取り付け部材１２０から抜けることが防止される。 In some embodiments, the connecting member 141 smoothly drives the second mounting member 120 and prevents the connecting member 141 from coming off the second mounting member 120 at the rear end 120b of the second mounting member 120. Is provided with a second slot 122 penetrating in the radial direction, the second slot 122 and the first slot 121 communicate with each other, and the length of the second slot 122 is equal to or greater than the length S1 of the first slot 121. .. Specifically, for example, the distance S3 from one side of the first slot 121 near the end face of the rear end 120b of the second mounting member 120 to the end face of the rear end 120b of the second mounting member 120 is about 2 mm. The width of the second slot 122 in the X direction is set to about 2.5 mm. In that case, the connecting member 141 is inserted into the first slot 121 and extends to the second slot 122, and the connecting member 141 is separated from the end surface of the rear end 120b of the second mounting member 120. Does not touch one side. As a result, the contact length between the connecting member 141 and the first slot 121 is reduced, and the distance between the portions of the connecting member 141 inserted into the second mounting member 120 is sufficiently increased, whereby the connecting member 141 becomes the first. 2 The mounting member 120 is smoothly driven, and the connecting member 141 is prevented from coming off from the second mounting member 120.

いくつかの実施形態では、掃除機用ブラシ構造１００の構造をコンパクト化するために、第１取り付け部材１１０のＺ方向の中央部には、第３スロット１１１が設けられ、第２取り付け部材１２０の後端１２０ｂは第３スロット１１１に収納される。具体的には、第１取り付け部材１１０は、略塊状であり、第３スロット１１１は、第１取り付け部材１１０のＺ方向の中央に開けられたノッチであり、この場合、第２取り付け部材１２０は略軸状であり、Ｚ方向の両側で面取りされており、第３スロット１１１のＺ方向における幅は第２取り付け部材１２０のＺ方向の幅よりもわずかに大きく、それによって、第２取り付け部材１２０はスムーズに揺動可能になる。第１取り付け部材１１０には、Ｚ方向において貫通する第１ヒンジ孔１１２が設けられ、第２取り付け部材１２０には、第１ヒンジ孔１１２と合わせる第２ヒンジ孔１２３が設けられ、第２ヒンジ孔１２３は、第１ヒンジ孔１１２よりもわずかに大きく設定してもよく、第１取り付け部材１１０には、ヒンジピン１５１が架設され、ヒンジピン１５１は、第１ヒンジ孔１１２と第２ヒンジ孔１２３のそれぞれに挿通され、それにより、第２取り付け部材１２０は第１取り付け部材１１０に対して自在に揺動可能である。第２取り付け部材１２０の後端１２０ｂが第３スロット１１１に収納されると、掃除機用ブラシ構造１００の構造をよりコンパクト化するだけでなく、第１取り付け部材１１０も第２取り付け部材１２０をより安定的に支持する。 In some embodiments, in order to make the structure of the brush structure 100 for a vacuum cleaner compact, a third slot 111 is provided at the center of the first mounting member 110 in the Z direction, and the second mounting member 120 The rear end 120b is housed in the third slot 111. Specifically, the first mounting member 110 is substantially massive, and the third slot 111 is a notch opened in the center of the first mounting member 110 in the Z direction. In this case, the second mounting member 120 is It is substantially axial and chamfered on both sides in the Z direction, and the width of the third slot 111 in the Z direction is slightly larger than the width of the second mounting member 120 in the Z direction, whereby the second mounting member 120 Can swing smoothly. The first mounting member 110 is provided with a first hinge hole 112 penetrating in the Z direction, and the second mounting member 120 is provided with a second hinge hole 123 to be matched with the first hinge hole 112, and the second hinge hole is provided. The 123 may be set slightly larger than the first hinge hole 112, and the hinge pin 151 is erected on the first mounting member 110, and the hinge pin 151 is the first hinge hole 112 and the second hinge hole 123, respectively. The second mounting member 120 can swing freely with respect to the first mounting member 110. When the rear end 120b of the second mounting member 120 is housed in the third slot 111, not only the structure of the brush structure 100 for the vacuum cleaner is made more compact, but also the first mounting member 110 is made of the second mounting member 120. Stable support.

いくつかの実施形態では、回転部１４０には、その周方向に分布している複数の羽根１４２が設けられ、回転部１４０は空気圧吸引力によって回転駆動される。具体的には、羽根１４２は、それぞれ回転部１４０の先端１４０ａと後端１４０ｂの間に配置されてもよく、羽根１４２の数は必要に応じて設定でき、たとえば本実施形態では、４枚の羽根１４２が設けられる。羽根１４２を周方向に均等に分布させるようにすると、回転部１４０は安定的に駆動される。さらに、羽根１４２は、回転部１４０に一体成形されてもよいし、取り外し可能な方式によって回転部１４０の先端１４０ａと後端１４０ｂの間に挿入されてもよい。 In some embodiments, the rotating portion 140 is provided with a plurality of blades 142 distributed in the circumferential direction thereof, and the rotating portion 140 is rotationally driven by pneumatic suction force. Specifically, the blades 142 may be arranged between the front end 140a and the rear end 140b of the rotating portion 140, respectively, and the number of blades 142 can be set as needed. For example, in the present embodiment, four blades 142 are provided. The blade 142 is provided. When the blades 142 are evenly distributed in the circumferential direction, the rotating portion 140 is stably driven. Further, the blade 142 may be integrally molded with the rotating portion 140, or may be inserted between the front end 140a and the rear end 140b of the rotating portion 140 by a removable method.

本実施形態では、回転部１４０に羽根１４２が設けられているため、回転部１４０は空気圧吸引力によって回転駆動され得る。たとえば、掃除機用ブラシ構造１００が負圧装置たとえば負圧式掃除機（図示せず）に接続される場合、負圧式掃除機はモータによって高速回転し、掃除機内の掃除機の羽根１４２を高速で回転させることで、密閉された掃除機のキャビティ内で空気真空を発生させて、ほこりを吸引する。このような場合、掃除機の羽根の高速回転による起動吸引力（負圧）は、回転部１４０の羽根１４２を駆動して、回転部１４０を回転させることができる。本実施形態では、掃除機用ブラシ構造１００は、回転部１４０に設けられた羽根１４２が、空気圧吸引力により回転駆動され、このように、掃除機用ブラシ構造１００の構造を大幅に簡素化させる。さらに、たとえば駆動装置、モータなどを省略できるため、補助電源を必要とせず、掃除機用ブラシ構造１００の作動に対する制御が容易になる。 In the present embodiment, since the rotating portion 140 is provided with the blade 142, the rotating portion 140 can be rotationally driven by the pneumatic suction force. For example, when the brush structure 100 for a vacuum cleaner is connected to a negative pressure device, for example, a negative pressure type vacuum cleaner (not shown), the negative pressure type vacuum cleaner is rotated at high speed by a motor, and the blade 142 of the vacuum cleaner in the vacuum cleaner is rotated at high speed. By rotating, an air vacuum is created in the cavity of the sealed vacuum cleaner to suck in dust. In such a case, the starting suction force (negative pressure) due to the high-speed rotation of the blades of the vacuum cleaner can drive the blades 142 of the rotating portion 140 to rotate the rotating portion 140. In the present embodiment, in the vacuum cleaner brush structure 100, the blades 142 provided in the rotating portion 140 are rotationally driven by pneumatic suction force, thus greatly simplifying the structure of the vacuum cleaner brush structure 100. .. Further, since, for example, a drive device, a motor, and the like can be omitted, an auxiliary power source is not required, and control for the operation of the brush structure 100 for a vacuum cleaner becomes easy.

もちろん、以上、羽根１４２が設けられた回転部１４０を例として説明したが、これに限定せず、回転部１４０はモータによって駆動されてもよい。 Of course, the rotating portion 140 provided with the blades 142 has been described above as an example, but the present invention is not limited to this, and the rotating portion 140 may be driven by a motor.

Further, since the tip 140a of the rotating portion 140 can be directly supported by the first mounting member 110, the structure becomes more compact. Of course, the mounting method of the rotating portion 140 is not limited to that, for example, in the rotating portion 140, only the tip 140a is supported by the first mounting member 110, and the blade 142 is installed at the rear end 140b of the rotating portion 140. The rotating portion 140 may be configured such that only the rear end 140b is supported by the bracket 152 and the blade 142 is installed at the tip 140a of the rotating portion 140.

いくつかの実施形態では、ブラシヘッド１３０を容易に交換可能にするために、ブラシヘッド１３０は、第２取り付け部材１２０の先端１２０ａに取り外し可能に取り付けられる。具体的には、ブラシヘッド１３０は、たとえばクランプ、螺合などの任意の公知の方式によって、第２取り付け部材１２０の先端１２０ａに取り外し可能に取り付けられる。ブラシヘッド１３０の長さは必要に応じて設定することができ、たとえば、ドアのコナー、花瓶のコナーや門のすき間などのほこりを簡便にはたくように５０ｍｍ以上に設定される。さらに、ブラシヘッド１３０の材料も必要に応じて選択でき、たとえば、選択し得るプラスチック材料は、たとえばＰＡ（ナイロン）、ＰＰ（ポリプロピレン）、ＰＢＴ（ポリブチレンテレフタレート）、ＰＥＴ（ポリテレフタル酸）、ＰＶＣ（ポリ塩化ビニル）など、又は、天然材料たとえば豚の毛、羊の毛、馬の毛などである。 In some embodiments, the brush head 130 is removably attached to the tip 120a of the second attachment member 120 so that the brush head 130 can be easily replaced.

(Polyvinyl chloride) or the like, or natural materials such as pig hair, sheep hair, horse hair and the like.

図５は、掃除機用ブラシ構造１００（または１００ａ）を備える掃除機２００の一実施形態の模式図である。本考案の第２態様の実施形態に係る掃除機２００は、集塵管２１０を有し、集塵管２１０の先端２１１には、上記実施形態の掃除機用ブラシ構造１００が取り付けられ、且つ、少なくともブラシヘッド１３０の先端は、集塵管２１０の先端２１１外へ突出する。具体的には、掃除機用ブラシ構造１００は、集塵管２１０内に直接設置されてもよく、掃除機用ブラシ構造１００がハウジング１５０を有する場合、掃除機用ブラシ構造１００は、ハウジング１５０を介して直接集塵管２１０の先端２１１に取り付けられてもよい。なお、本実施形態の掃除機２００は、公知の市販掃除機であり得、家庭用の真空掃除機であってもよいし、産業用の真空掃除機であってもよいし、他の動力の掃除機であってもよく、回転部１４０を回転駆動できるものであればよい。 FIG. 5 is a schematic view of an embodiment of a vacuum cleaner 200 having a vacuum cleaner brush structure 100 (or 100a). The vacuum cleaner 200 according to the second embodiment of the present invention has a dust collecting pipe 210, and the brush structure 100 for the vacuum cleaner of the above embodiment is attached to the tip 211 of the dust collecting pipe 210. At least the tip of the brush head 130 projects out of the tip 211 of the dust collecting pipe 210. Specifically, the brush structure 100 for a vacuum cleaner may be installed directly in the dust collecting pipe 210, and when the brush structure 100 for a vacuum cleaner has a housing 150, the brush structure 100 for a vacuum cleaner has a housing 150. It may be directly attached to the tip 211 of the dust collecting pipe 210 via. The vacuum cleaner 200 of the present embodiment may be a known commercially available vacuum cleaner, may be a household vacuum cleaner, may be an industrial vacuum cleaner, or may be of another power source. It may be a vacuum cleaner, as long as it can rotationally drive the rotating portion 140.

家庭用の真空掃除機の場合、上記掃除機用ブラシ構造１００が設けられているので、集塵するとともに、ドアのコナー、花瓶のコナーや門のすき間などにおけるほこりをはたくことができ、したがって、ほこりをより容易に吸引でき、そして集塵管２１０をはたく動作により障子紙や花瓶などを壊すことを防止する。また、掃除機用ブラシ構造１００は、揺動方式でブラシヘッド１３０を駆動するので、長くて柔軟な刷毛を使用しても、ブラシヘッド１３０の絡み合いを防止できる。さらに、掃除機用ブラシ構造１００は、直接偏心軸構造の連結部材１４１を介して、ブラシヘッド１３０が取り付けられた第２取り付け部材１２０を駆動するので、その構造が簡単になる。そして、掃除機用ブラシ構造１００の回転部１４０は負圧駆動羽根１４２を通じて回転して第２取り付け部材１２０を揺動駆動することによって、補助電源を不要にするだけでなく、掃除機用ブラシ構造１００の作動に対する制御が容易になる。 In the case of a vacuum cleaner for home use, since the brush structure 100 for the vacuum cleaner is provided, it is possible to collect dust and dust in door conners, vase conners, gate gaps, etc. Dust can be sucked more easily, and the action of tapping the dust collecting tube 210 prevents the shoji paper, the vase, etc. from being broken. Further, since the brush structure 100 for a vacuum cleaner drives the brush head 130 in a swinging manner, it is possible to prevent the brush head 130 from being entangled even if a long and flexible brush is used. Further, the vacuum cleaner brush structure 100 drives the second attachment member 120 to which the brush head 130 is attached directly via the connecting member 141 of the eccentric shaft structure, so that the structure is simplified. Then, the rotating portion 140 of the brush structure 100 for a vacuum cleaner rotates through the negative pressure drive blade 142 to swing drive the second mounting member 120, thereby not only eliminating the need for an auxiliary power supply but also having a brush structure for a vacuum cleaner. It becomes easier to control the operation of 100.
