上記特許文献１の掃除補助具は、羽根車を風路の内部を流れる吸気の作用により回転させることができ、モーターやモーターを駆動させる電源等を必要としないという利点を有するものであったが、羽根車と、羽根車の回転をハウジングの先端に導く伝動軸が、塵埃等を吸引する風路が形成されたハウジング内に設置されていることから、吸引された髪の毛等の塵埃が羽根車や伝動軸に巻き付いた場合には故障する原因となるため、羽根車や伝動軸等の駆動部のメンテナンスを頻繁に行う必要があった。 The cleaning aid of Patent Document 1 has the advantage that the impeller can be rotated by the action of the intake air flowing inside the air passage and does not require a motor or a power source for driving the motor. Since the impeller and the transmission shaft that guides the rotation of the impeller to the tip of the housing are installed in the housing in which the air passage for sucking dust is formed, dust such as sucked hair is collected by the impeller. If it is wound around the transmission shaft, it may cause a failure, so that it is necessary to frequently perform maintenance of the driving unit such as the impeller and the transmission shaft.

一方、特許文献２の吸引式毛切断装置は、羽根車を回転させる風路と切断された毛を吸引する風路とを分けることによって、上記特許文献１の掃除補助具が有していた課題を解決するものであった。しかしながら、電気掃除機の吸引時において、バリカンの刃を交換したい場合には、安全上、刃のみを交換することはできず、吸引式毛切断装置本体を電気掃除機から取り外す必要があった。 On the other hand, the suction-type hair cutting device of Patent Document 2 has a problem that the cleaning assisting tool of Patent Document 1 has by dividing the air path for rotating the impeller and the air path for sucking the cut hair. It was something to solve. However, if the blade of the clipper is to be replaced at the time of suction by the vacuum cleaner, it is not possible to replace only the blade for safety, and it is necessary to remove the suction-type hair cutting device main body from the vacuum cleaner.

本発明は、上記課題を解決する為になされたもので、塵埃を除去する機構を駆動させるための駆動部にモーターや電源等を必要とせず、製造コストの低減を図ることができると共に、前記駆動部のメンテナンスを必要とせず、電気掃除機の吸引時においても接続されているアタッチメントのみの交換作業を安全に行うことができる清掃用具を提供することを目的としている。 The present invention has been made to solve the above problems, and does not require a motor, a power source, or the like for a driving unit for driving a mechanism for removing dust, and can reduce the manufacturing cost. It is an object of the present invention to provide a cleaning tool that does not require maintenance of the drive unit and can safely perform replacement work of only the attached attachment even during suction of a vacuum cleaner.

上記従来の課題を解決する為に、請求項１の発明は、被清掃面に付着した塵埃等の清掃をする為に使用する清掃用具において、該清掃用具は、本体部と、該本体部に着脱自在に嵌合されたアタッチメントとにより形成されてあり、前記本体部は、吸引風路と、回転駆動部とを有し、前記吸引風路は、一端が電気掃除機の吸引パイプに連通すると共に、他端に吸引開口を有し、前記回転駆動部は、前記本体部に取り入れられた吸引風により回転するファンと、該ファンに連動する減速機構と、該減速機構に連結する回転駆動伝達部とを有し、前記アタッチメントは、前記本体部の前記吸引開口にたいして嵌合可能な吸引風路接続部と、前記回転駆動伝達部にたいして嵌合可能な回転駆動連結部と、前記吸引風路接続部に連通して被清掃面に付着した塵埃等を吸引する為の吸引口を備え、回転駆動伝達部の動力により被清掃面の塵埃を除去する塵埃除去部とを有し、前記電気掃除機の吸引時において、前記本体部と前記アタッチメントとの嵌合が外れた状態では、前記吸引風路に流れる単位時間当たりの風量が増加することによって、前記回転駆動伝達部における回転運動が停止又は減速することを特徴としている。したがって、電気掃除機の吸引力によって、ファンを回転させ、塵埃除去部を動かして被清掃面に付着した塵埃等を剥がした後、該塵埃等は、吸引風路を経由して電気掃除機本体へと運ばれるので、ファンを回転させるモーターや電源を必要とせず、製造コストの低減を図ることができる。 In order to solve the above-mentioned conventional problems, the invention of claim 1 is a cleaning tool used for cleaning dust or the like adhering to a surface to be cleaned. The cleaning tool includes a main body portion and a main body portion. The main body portion has a suction air passage and a rotation driving portion, and one end of the suction air passage communicates with a suction pipe of a vacuum cleaner. In addition, the rotation drive unit has a suction opening at the other end, and the rotation drive unit is rotated by the suction air taken into the main body unit, a speed reduction mechanism interlocked with the fan, and a rotation drive transmission coupled to the speed reduction mechanism.

Therefore, after the fan is rotated by the suction force of the vacuum cleaner and the dust removing unit is moved to remove the dust and the like adhering to the surface to be cleaned, the dust etc. passes through the suction air passage to Therefore, a motor and a power source for rotating the fan are not required, and the manufacturing cost can be reduced.

また、吸引風路内に回転駆動部を設置していないので、吸引された塵埃等により、回転駆動部が故障するおそれが無く、頻繁にメンテナンスを行う必要がない。さらに、本体部とアタッチメントとの嵌合が外れた状態で回転駆動伝達部における回転運動を停止又は減速させることができるので、電気掃除機の吸引時においても接続されているアタッチメントのみの交換作業を安全に行うことができると共に、回転駆動伝達部が破壊されるのを防ぐことができる。 In addition, since the rotation drive unit is not installed in the suction air passage, there is no possibility that the rotation drive unit will be damaged by sucked dust or the like, and it is not necessary to perform maintenance frequently. Furthermore, since the rotational movement in the rotational drive transmission part can be stopped or decelerated in a state where the fitting between the main body part and the attachment is released, only the attached attachment can be replaced even during suction of the vacuum cleaner. It can be performed safely and can prevent the rotation drive transmission unit from being destroyed.

請求項２の発明は、被清掃面に付着した塵埃等の清掃をする為に使用する清掃用具において、該清掃用具は、本体部と、該本体部に着脱自在に嵌合されたアタッチメントとにより形成されてあり、前記本体部は、吸引風路と、回転駆動部とを有し、前記吸引風路は、一端が電気掃除機の吸引パイプに連通すると共に、他端に吸引開口を有し、前記回転駆動部は、前記本体部に取り入れられた吸引風により回転するファンと、該ファンに連動する減速機構と、該減速機構に連結する回転駆動伝達部とを有すると共に、前記減速機構及び前記回転駆動伝達部は、各々の内部空間に塵埃等が入り込まないように密閉された構造を有するものであって、前記アタッチメントは、前記本体部の前記吸引開口にたいして嵌合可能な吸引風路接続部と、前記回転駆動伝達部にたいして嵌合可能な回転駆動連結部と、前記吸引風路接続部に連通して被清掃面に付着した塵埃等を吸引する為の吸引口を備え、回転駆動伝達部の動力により被清掃面の塵埃を除去する塵埃除去部とを有し、前記電気掃除機の吸引時において、前記本体部と前記アタッチメントとの嵌合が外れた状態では、前記吸引風路に流れる単位時間当たりの風量が増加することによって、前記回転駆動伝達部における回転運動が停止又は減速することを特徴としている。したがって、電気掃除機の吸引力によって、ファンを回転させ、塵埃除去部を動かして被清掃面に付着した塵埃等を剥がした後、該塵埃等は、吸引風路を経由して電気掃除機本体へと運ばれるので、ファンを回転させるモーターや電源を必要とせず、製造コストの低減を図ることができる。 The invention of claim 2 is a cleaning tool used for cleaning dust adhering to the surface to be cleaned, the cleaning tool comprising a main body portion and an attachment detachably fitted to the main body portion. The main body portion has a suction air passage and a rotation drive portion, and the suction air passage has one end communicating with a suction pipe of a vacuum cleaner and a suction opening at the other end. The rotation drive unit includes a fan that is rotated by suction air taken into the main body, a speed reduction mechanism that is linked to the fan, and a rotation drive transmission unit that is connected to the speed reduction mechanism. The rotational drive transmission unit has a structure that is sealed so that dust or the like does not enter each internal space, and the attachment is connected to a suction air passage that can be fitted to the suction opening of the main body unit Part and said A rotation drive connecting portion that can be fitted to the rotation drive transmission portion, and a suction port that is connected to the suction air passage connection portion and sucks dust or the like adhering to the surface to be cleaned. A dust removing section for removing dust on the surface to be cleaned, and when the vacuum cleaner is sucked, when the main body and the attachment are disengaged, the unit per unit time flowing through the suction air passage As the air volume increases, the rotational movement in the rotational drive transmission unit is stopped or decelerated. Therefore, after the fan is rotated by the suction force of the vacuum cleaner and the dust removing unit is moved to remove the dust and the like adhering to the surface to be cleaned, the dust etc. passes through the suction air passage to Therefore, a motor and a power source for rotating the fan are not required, and the manufacturing cost can be reduced.

また、吸引風路内に回転駆動部を設置していないと共に、減速機構及び回転駆動伝達部は、各々の内部空間に塵埃等が入り込まないように密閉された構造を有しているので、減速機構及び回転駆動伝達部に吸引された塵埃等が入り込み、噛み込んで動作不良が発生したり、駆動停止等の発生がない。また、吸引された塵埃等により、回転駆動部が故障するおそれが無く、頻繁にメンテナンスを行う必要がない。さらに、本体部とアタッチメントとの嵌合が外れた状態で回転駆動伝達部における回転運動を停止又は減速させることができるので、電気掃除機の吸引時においても接続されているアタッチメントのみの交換作業を安全に行うことができると共に、回転駆動伝達部が破壊されるのを防ぐことができる。 In addition, the rotation drive unit is not installed in the suction air passage, and the speed reduction mechanism and the rotation drive transmission unit have a sealed structure so that dust or the like does not enter each internal space.

Further, there is no possibility that the rotary drive unit will break down due to sucked dust or the like, and it is not necessary to perform frequent maintenance. Furthermore, since the rotational movement in the rotational drive transmission part can be stopped or decelerated in a state where the fitting between the main body part and the attachment is released, only the attached attachment can be replaced even during suction of the vacuum cleaner. It can be performed safely and can prevent the rotation drive transmission unit from being destroyed.

以下、本発明の実施の形態について、図面を参照しながら説明する。なお、この実施の形態により本発明が限定されるものではない。 Hereinafter, embodiments of the present invention will be described with reference to the drawings. In addition, this invention is not limited by this embodiment.

図１は、本発明に係る清掃用具の第１実施形態を示す平面図であり、図２は、同正面図、図３は図２のＡ−Ａ断面図である。これらの図を用いて第１実施形態の清掃用具を説明する。第１実施形態の清掃用具１０は、本体部１と、この本体部１に着脱自在に嵌合されたアタッチメント２とにより形成されている。 FIG. 1 is a plan view showing a first embodiment of a cleaning tool according to the present invention, FIG. 2 is a front view thereof, and FIG. 3 is a cross-sectional view taken along line AA of FIG. The cleaning tool of 1st Embodiment is demonstrated using these figures. The cleaning tool 10 of 1st Embodiment is formed of the main-body part 1 and the attachment 2 fitted to this main-body part 1 so that attachment or detachment was possible.

そして、本体部１は、吸引風路３と、回転駆動部４とを有し、吸引風路３は、一方の端部１ａが電気掃除機の吸引パイプ（図示せず）に連通すると共に、他方の端部に吸引開口３ａを有し、回転駆動部４は、本体部１に取り入れられた吸引風により回転するファン４ａと、このファン４ａに連動する減速機構４ｂと、この減速機構４ｂに連結する回転駆動伝達部４ｃと、ファン４ａを回転させる為に外部から空気を取り込むファン用吸引口２１を有している。ここで、減速機構４ｂと、回転駆動伝達部４ｃは、各々の内部空間４１、４２に塵埃等が入り込まないように密閉された構造を有している。したがって、吸引された塵埃等により、回転駆動部４が故障するおそれが無く、頻繁に内部清掃等のメンテナンスを行う必要がないという利点がある。ここで、減速機構４ｂには、遊星ギアを使用している。遊星ギアは、コンパクトな構成であると共に、回転軸が１本で、回転速度を減速させることができる。尚、回転駆動伝達部４ｃは、図３に示す位置から本体部１側に後退させて、本体部１の外側枠内に入れることもできる。 And the main-body part 1 has the suction air path 3 and the rotation drive part 4, and while the one end part 1a is connected to the suction pipe (not shown) of a vacuum cleaner, the suction air path 3, The other end portion has a suction opening 3a, and the rotation drive unit 4 includes a fan 4a that is rotated by suction air taken into the main body 1, a speed reduction mechanism 4b that is linked to the fan 4a, and a speed reduction mechanism 4b. A rotation drive transmission unit 4c to be connected and a fan suction port 21 for taking in air from the outside in order to rotate the fan 4a are provided. Here, the speed reduction mechanism 4b and the rotational drive transmission unit 4c have a sealed structure so that dust or the like does not enter the internal spaces 41 and 42, respectively. Therefore, there is an advantage that there is no possibility that the rotary drive unit 4 will break down due to sucked dust or the like, and there is no need to frequently perform maintenance such as internal cleaning. Here, a planetary gear is used for the speed reduction mechanism 4b. The planetary gear has a compact configuration and a single rotation shaft, and can reduce the rotation speed. The rotational drive transmission portion 4c can be retracted from the position shown in FIG. 3 toward the main body 1 and placed in the outer frame of the main body 1.

また、アタッチメント２は、本体部１の吸引開口３ａにたいして嵌合可能な吸引風路接続部５と、回転駆動伝達部４ｃにたいして嵌合可能な回転駆動連結部６と、吸引風路接続部５に連通して被清掃面に付着した塵埃等を吸引する為の吸引口５ａを備え、回転駆動伝達部４ｃの動力により被清掃面の塵埃を除去する塵埃除去部６ａとを有している。 Further, the attachment 2 is connected to the suction air passage connecting portion 5 that can be fitted to the suction opening 3 a of the main body portion 1, the rotational drive connecting portion 6 that can be fitted to the rotational drive transmission portion 4 c, and the suction air passage connecting portion 5. A suction port 5a for sucking dust and the like adhering to the surface to be cleaned in communication is provided, and a dust removing unit 6a for removing dust on the surface to be cleaned by the power of the rotational drive transmission unit 4c.

そして、回転駆動連結部６の一方の端部は、回転軸７の一方の端部であり、回転駆動伝達部４ｃと嵌合し、回転駆動連結部６の他方の端部は、回転軸７の他方の端部であり、ネジ８によって塵埃除去部６ａに固定されている。ここで、塵埃除去部６ａは、断面略コ字状に形成されており、開口が吸引口５ａとなり、底面に形成されている複数の塵埃吸引孔６ｂ、６ｂ・・から絞り風路２３へと塵埃が排出される構造となっている。したがって、被清掃面に付着している塵埃は、回転する塵埃除去部６ａの先端に接触することによって剥がされ、吸引口５ａから吸引され、塵埃吸引孔６ｂから絞り風路２３を経由して吸引風路３へと吸引されるのである。 One end portion of the rotation drive connecting portion 6 is one end portion of the rotating shaft 7 and is fitted to the rotation drive transmitting portion 4 c, and the other end portion of the rotation drive connecting portion 6 is the rotation shaft 7. And is fixed to the dust removing portion 6a by a screw 8. Here, the dust removing portion 6a has a substantially U-shaped cross section, and the opening serves as the suction port 5a. From the plurality of dust suction holes 6b, 6b,. It has a structure in which dust is discharged. Accordingly, the dust adhering to the surface to be cleaned is peeled off by contacting the tip of the rotating dust removing portion 6a, sucked from the suction port 5a, and sucked from the dust suction hole 6b via the throttle air passage 23. The air is sucked into the air passage 3.

また、清掃用具１０は、図示しない電気掃除機の吸引時において、本体部１とアタッチメント２との嵌合が外れた状態では、吸引風路３に流れる単位時間当たりの風量が増加することによって、回転駆動伝達部４ｃにおける回転運動が停止又は減速する構造となっている。 In addition, the cleaning tool 10 has an increase in the amount of air per unit time flowing through the suction air passage 3 in a state in which the main body 1 and the attachment 2 are disengaged during suction of a vacuum cleaner (not shown). The rotational drive transmission unit 4c has a structure in which the rotational motion is stopped or decelerated.

即ち、図示しない電気掃除機の吸引力が一定の場合において、本体部１とアタッチメント２とが嵌合されている状態では、吸引口５ａから吸引される空気は、吸引風路３の開口径よりも小さい開口径を有する絞り風路２３を通過しているので、吸引風路３に流れる単位時間当たりの風量は、本体部１とアタッチメント２との嵌合が外れた状態の吸引風路３に流れる単位時間当たりの風量よりも小さくなっている。したがって、ファン用吸引口２１から吸引される単位時間あたりの風量は、本体部１とアタッチメント２との嵌合が外れた状態では、減少することとなり、ファン４ａの回転が停止又は減速状態となるので、回転駆動伝達部４ｃにおける回転運動が停止又は減速することとなる。 That is, when the suction force of a vacuum cleaner (not shown) is constant, the air sucked from the suction port 5a is larger than the opening diameter of the suction air passage 3 when the main body 1 and the attachment 2 are fitted. Since the air flow per unit time flowing through the suction air passage 3 is in the suction air passage 3 in a state in which the main body 1 and the attachment 2 are disengaged. It is smaller than the air flow per unit time. Therefore, the air volume per unit time sucked from the fan suction port 21 is reduced when the main body 1 and the attachment 2 are disengaged, and the rotation of the fan 4a is stopped or decelerated. Therefore, the rotational motion in the rotational drive transmission unit 4c is stopped or decelerated.

ここで、本体部１とアタッチメント２との嵌合は、回転駆動伝達部４ｃと回転駆動連結部６の嵌合の後、吸引開口３ａと吸引風路接続部５が嵌合されるように形成されている。したがって、回転駆動伝達部４ｃと回転駆動連結部６の嵌合のみが完了している状態では、吸引風路３に流れる単位時間当たりの風量が増加した状態となっているので、回転駆動伝達部４ｃにおける回転運動は停止又は減速した状態を維持することができ、安全に本体部１とアタッチメント２の嵌合作業を行うことができる。 Here, the main body 1 and the attachment 2 are fitted so that the suction opening 3a and the suction air passage connecting portion 5 are fitted after the rotation drive transmission portion 4c and the rotation drive connecting portion 6 are fitted. Has been. Therefore, in the state where only the rotation drive transmission portion 4c and the rotation drive connecting portion 6 are fitted, the air volume per unit time flowing through the suction air passage 3 is increased, so that the rotation drive transmission portion The rotational motion in 4c can maintain the state stopped or decelerated, and the fitting operation | work of the main-body part 1 and the attachment 2 can be performed safely.

図４は、本発明に係る清掃用具の第２実施形態を示す平面図であり、図５は、同正面図、図６は図５のＢ−Ｂ断面図である。これらの図を用いて第２実施形態の清掃用具を説明する。第２実施形態の清掃用具２０は、本体部１１と、この本体部１１に着脱自在に嵌合されたアタッチメント１２とにより形成されている。 4 is a plan view showing a second embodiment of the cleaning tool according to the present invention, FIG. 5 is a front view of the same, and FIG. 6 is a sectional view taken along line BB of FIG. The cleaning tool of 2nd Embodiment is demonstrated using these figures. The cleaning tool 20 of the second embodiment is formed by a main body 11 and an attachment 12 that is detachably fitted to the main body 11.

そして、本体部１１は、吸引風路１３と、回転駆動部１４とを有し、吸引風路１３は、一方の端部１１ａが電気掃除機の吸引パイプ（図示せず）に連通すると共に、他方の端部に吸引開口１３ａを有し、回転駆動部１４は、本体部１１に取り入れられた吸引風により回転するファン１４ａと、このファン１４ａに連動する減速機構１４ｂと、この減速機構１４ｂに連結する回転駆動伝達部１４ｃと、ファン１４ａを回転させる為に外部から空気を取り込むファン用吸引口２２を有している。ここで、減速機構１４ｂと、回転駆動伝達部１４ｃは、各々の内部空間４３、４４に塵埃等が入り込まないように密閉された構造を有している。したがって、吸引された塵埃等により、回転駆動部１４が故障するおそれが無く、頻繁に内部清掃等のメンテナンスを行う必要がないという利点がある。ここで、減速機構１４ｂには、遊星ギアを使用している。遊星ギアは、コンパクトな構成であると共に、回転軸が１本で、回転速度を減速させることができる。また、ファン用吸引口２２を、本体部１１の下側に設けることによって、ファンから発生する音を減少させている。尚、回転駆動伝達部１４ｃは、図６に示す位置から本体部１１側に後退させて、本体部１１の外側枠内に入れることもできる。 And the main-body part 11 has the suction air path 13 and the rotation drive part 14, and while the one end part 11a is connected to the suction pipe (not shown) of a vacuum cleaner, the suction air path 13 is, The other end portion has a suction opening 13a, and the rotation drive unit 14 includes a fan 14a that is rotated by suction air taken into the main body 11, a speed reduction mechanism 14b that is linked to the fan 14a, and a speed reduction mechanism 14b. The rotation drive transmission part 14c to be connected and the fan suction port 22 for taking in air from the outside in order to rotate the fan 14a are provided. Here, the speed reduction mechanism 14b and the rotational drive transmission portion 14c have a sealed structure so that dust and the like do not enter the internal spaces 43 and 44, respectively. Accordingly, there is an advantage that there is no possibility that the rotary drive unit 14 is broken due to sucked dust or the like, and it is not necessary to frequently perform maintenance such as internal cleaning. Here, a planetary gear is used for the speed reduction mechanism 14b. The planetary gear has a compact configuration and a single rotation shaft, and can reduce the rotation speed. Further, by providing the fan suction port 22 on the lower side of the main body 11, the sound generated from the fan is reduced. The rotational drive transmission portion 14 c can be retracted from the position shown in FIG. 6 toward the main body portion 11 and placed in the outer frame of the main body portion 11.

また、アタッチメント１２は、本体部１１の吸引開口１３ａにたいして嵌合可能な吸引風路接続部１５と、回転駆動伝達部１４ｃにたいして嵌合可能な回転駆動連結部１６と、吸引風路接続部１５に連通して被清掃面に付着した塵埃等を吸引する為の吸引口１５ａを備え、回転駆動伝達部１４ｃの動力により被清掃面の塵埃を除去する塵埃除去部１６ａとを有している。 The attachment 12 is connected to the suction air passage connection portion 15 that can be fitted to the suction opening 13 a of the main body portion 11, the rotation drive connection portion 16 that can be fitted to the rotation drive transmission portion 14 c, and the suction air passage connection portion 15. There is provided a suction port 15a for communicating dust and the like adhering to the surface to be cleaned in communication, and a dust removing unit 16a for removing dust on the surface to be cleaned by the power of the rotational drive transmission unit 14c.

そして、回転駆動連結部１６の一方の端部は、回転軸１７ａの一方の端部であり、回転駆動伝達部１４ｃと嵌合し、回転駆動連結部１６の他方の端部は、回転軸１７ａの他方の端部であり、ギア１９ａが形成されており、回転軸１７ｂの一方の端部に形成されているギア１９ｂと噛合うことで、回転軸の長手方向が略９０度変換されている。そして、回転軸１７ｂの他方の端部がネジ１８によって塵埃除去部１６ａに固定されている。ここで、塵埃除去部１６ａは、断面略コ字状に形成されており、開口が吸引口１５ａとなり、底面に形成されている複数の塵埃吸引孔１６ｂ、１６ｂ・・から絞り風路２４へと塵埃が排出される構造となっている。したがって、被清掃面に付着している塵埃は、回転する塵埃除去部１６ａの先端に接触することによって剥がされ、吸引口１５ａから吸引され、塵埃吸引孔１６ｂから絞り風路２４を経由して吸引風路１３へと吸引されるのである。 One end portion of the rotation drive connecting portion 16 is one end portion of the rotation shaft 17a and is fitted to the rotation drive transmitting portion 14c, and the other end portion of the rotation drive connecting portion 16 is the rotation shaft 17a. The gear 19a is formed, and the longitudinal direction of the rotating shaft is changed by approximately 90 degrees by meshing with the gear 19b formed at one end of the rotating shaft 17b. . The other end of the rotating shaft 17b is fixed to the dust removing portion 16a with a screw 18. Here, the dust removing portion 16a is formed in a substantially U-shaped cross section, and the opening serves as the suction port 15a. From the plurality of dust suction holes 16b, 16b,. It has a structure in which dust is discharged. Accordingly, the dust adhering to the surface to be cleaned is peeled off by contacting the tip of the rotating dust removing portion 16a, sucked from the suction port 15a, and sucked from the dust suction hole 16b via the throttle air passage 24. The air is sucked into the air passage 13.

また、清掃用具２０は、図示しない電気掃除機の吸引時において、本体部１１とアタッチメント１２との嵌合が外れた状態では、吸引風路１３に流れる単位時間当たりの風量が増加することによって、回転駆動伝達部１４ｃにおける回転運動が停止又は減速する構造となっている。この原理については、第１実施形態の清掃用具１０で説明したものと同様であるので、省略する。 In addition, the cleaning tool 20 has an increase in the amount of air per unit time flowing through the suction air passage 13 in a state in which the main body 11 and the attachment 12 are disengaged during suction of a vacuum cleaner (not shown). The rotational drive transmission unit 14c has a structure in which the rotational motion is stopped or decelerated. Since this principle is the same as that described in the cleaning tool 10 of the first embodiment, a description thereof will be omitted.

尚、本発明は、上記第１実施形態及び第２実施形態に限定されるものではなく、種々の実施形態を採用することができることは言うまでもない。例えば、上記実施形態において、吸引風路接続部５、１５と吸引開口３ａ、１３ａとの間を、手動のスライド板や自動の開閉弁によって遮断した場合には、回転駆動部４、１４の回転数を増加させることができるので、アタッチメントの先端部を変更することによって、ポリッシング清掃等の磨き掃除専用に使用することも可能としている。また、アタッチメント２、１２は、回転駆動伝達部４ｃ、１４ｃの回転運動を、塵埃除去部６ａ、１６ａの被清掃面にたいする水平方向運動、上下方向運動、回転方向運動の中の少なくとも１方向以上の運動に変換する駆動変換部（例えば、第２実施形態における回転軸１７ａ、１７ｂと、ギア１９ａ、１９ｂの構成）を備える態様とすることもでき、これも本発明に含まれる。さらにまた、本体部１、１１の減速機構４ｂ、１４ｂと、回転駆動伝達部４ｃ、１４ｃは、各々の内部空間４１、４２、４３、４４に塵埃等が入り込まないように密閉された構造を有しているが、アタッチメント２、１２の回転駆動連結部６、１６と回転軸７、１７ａ、１７ｂの各々の内部空間においても、塵埃等が入り込まないように密閉された構造を採用できる。前記形態を採用した場合には、清掃用具１０、２０の使用時において、本体部１、１１の減速機構４ｂ、１４ｂ及び回転駆動伝達部４ｃ、１４ｃ、アタッチメント２、１２の回転駆動連結部６、１６及び回転軸７、１７ａ、１７ｂの各々の内部空間に塵埃等が入り込まない為、塵埃による故障等の発生がない。また、頻繁にメンテナンスを行う必要がない。 Needless to say, the present invention is not limited to the first and second embodiments, and various embodiments can be adopted. For example, in the above embodiment, when the suction air passage connecting portions 5 and 15 and the suction openings 3a and 13a are blocked by a manual slide plate or an automatic opening / closing valve, the rotation of the rotation drive portions 4 and 14 is performed. Since the number can be increased, by changing the tip of the attachment, it can be used exclusively for polishing cleaning such as polishing cleaning. Also, the attachments 2 and 12 are arranged so that the rotational movements of the rotational drive transmission units 4c and 14c are at least one of the horizontal movement, the vertical movement, and the rotational movement with respect to the surfaces to be cleaned of the dust removing sections 6a and 16a. A drive conversion unit (for example, the configuration of the rotation shafts 17a and 17b and the gears 19a and 19b in the second embodiment) that converts to motion may be included, and this is also included in the present invention. Furthermore, the speed reduction mechanisms 4b and 14b of the main body parts 1 and 11 and the rotational drive transmission parts 4c and 14c have a sealed structure so that dust and the like do not enter the internal spaces 41, 42, 43, and 44, respectively. However, it is possible to adopt a sealed structure so that dust or the like does not enter in the internal spaces of the rotation drive connecting portions 6 and 16 and the rotation shafts 7, 17 a, and 17 b of the attachments 2 and 12. In the case of adopting the form, when the cleaning tools 10 and 20 are used, the speed reduction mechanisms 4b and 14b of the main body parts 1 and 11, the rotational drive transmission parts 4c and 14c, the rotational drive connecting parts 6 of the attachments 2 and 12, 16 and the rotary shafts 7, 17a, 17b do not enter the internal spaces of the rotary shafts 7, 17a, and 17b, so that no trouble or the like is caused by the dust. Also, frequent maintenance is not necessary.

本発明の清掃用具は、電気掃除機の吸引パイプに接続されて、被清掃面に付着した塵埃等の除去や被清掃面のポリッシングに使用される。 The cleaning tool of the present invention is connected to a suction pipe of a vacuum cleaner, and is used for removing dust and the like adhering to the surface to be cleaned and polishing the surface to be cleaned.
