description | PROBLEM TO BE SOLVED: To provide a manually-operated vacuum cleaner which effectively collect sticky dirt and dust at a small part and which can be easily used. SOLUTION: In this construction, an extensible bag for mounting a jet nozzle and an air suction valve is housed in an outer shell for mounting a suction coat nozzle and a dust collector, a pressurizing rod for pressing the extensible bag is connected with a pressing handle outside of the shell via an elastic film or an air-tight hole, the extension and contraction of the bag for discharging air forms an increased space with the outer shell to cause pressure reduction for suction. When restoring extension, the air suction valve is opened and air flows to the bag from the outer bag, thereby reverse air flow never occurs at the end part of the nozzle. COPYRIGHT: (C)2004,JPO |
