发明名称 SUCTION PORT BODY OF VACUUM CLEANER
摘要 PROBLEM TO BE SOLVED: To efficiently and surely suck dust and refuse near a wall surface by forming a specified number or more of slits or openings in the connecting part of a bumper with a guard so that the guard is bendable from the connecting part to the sucking port side by the negative pressure within a suction chamber. SOLUTION: When a cleaning of a carpet or flooring is started, a guard 8 suspended from a bumper 7 is inclined from the root part having weak elastic force formed with small holes 12 toward a horizontally long sucking port 4 side by the negative pressure caused within a suction chamber 5. According to this, an air passage is ensured between the bumper 7 and a wall surface. Since the air velocity carried between the bumper 7 and the wall surface is raised as a suction port body 1 approaches the wall surface, whereby the guard 8 is further pressed, the guard 8 is inclined more deeply from the root part toward the horizontally long suction port 4 side. The dust at the wall edge can be smoothly blown off and moved to the horizontally long suction port 4.
