Zusammenfassung:The present invention relates to a vacuum cleaner, and there is provided a nonpowered vacuum cleaner comprising: a housing having a moving handle at one side of an upper surface, an open/close hole on a bottom surface, and an inhalation hole provided at a bottom of a front portion thereof; an exhaust hole provided on the other side of the upper surface of the housing; rolling wheels coupled with both sides of the housing, respectively; a gear portion which is mounted inside the housing and provided to convert and deliver a rotational force of a shaft of the rolling wheel; an inhalation fan which is provided to take air in from the inhalation hole and rotates by the rotational force delivered from the gear portion; a cleaning roller which is coupled with a rear end of the bottom of the housing and removed therefrom, wherein an outer circumferential surface of the cleaning roller is made of an adhesive collecting surface. Since the nonpowered vacuum cleaner according to the present invention can be operated by human power without requiring an external power source, the vacuum cleaner can be used in a place where electricity is not available. And, a size of the vacuum cleaner can be reduced such that the vacuum cleaner can be utilized on a table, since a gear structure for rotating an inner fan is simple. Also, a constant dust suction power can be maintained by incorporating a freewheel structure. Furthermore, since a cleaning roller having an adhesive outer circumferential surface is provided on the bottom of the cleaner and the cleaning roller is operated to protrude to outside only when an operation lever is held for a cleaning job, it is possible to perform cleaning efficiently and maintain a constant viscosity. 본 발명은 진공청소기에 관한 것으로, 상면 일측에 이동용 손잡이가 마련되고, 저면에 개폐구가 형성되고, 전면부 하단에 흡기구가 마련되는 하우징; 상기 하우징의 상면 타측에 마련되는 배기구; 상기 하우징의 양 측면에 결합되는 구름바퀴; 상기 하우징 내부에 장착되고, 상기 구름바퀴 축의 회전력을 변환하여 전달하도록 마련되는 기어부; 상기 흡기구로부터 공기를 흡입하도록 마련되고, 상기 기어부로부터 회전력을 전달받아 회전되도록 마련되는 흡기팬; 상기 하우징의 저면 후단에 분리 가능하게 결합되고, 외주면이 점착식 포집면으로 이루어지는 청소롤러를 포함하는 무동력 진공청소기가 제공된다. 본 발명에 따른 무동력 진공청소기는 외부 동력원을 필요로 하지 않고 사용자의 인력에 의해 작동될 수 있어 전기를 사용할 수 없는 장소에서 사용이 가능가고, 내부의 팬을 회전시키기 위한 기어구조가 간결하므로 소형화가 가능하여 탁상용으로 적용할 수 있으며, 프리휠 구조를 포함함으로써 일정한 먼지 흡입이 이뤄질 수 있다. 또한 점착성 외주면을 갖는 청소롤러가 저면에 구비되고, 청소를 위해 작동레버를 파지했을 시에만 외부로 돌출되도록 작동하므로 효율적인 청소가 가능하고 점착력을 유지하기 위한 관리가 용이하다.
