Description

technical field

[0001] The present invention relates to electric vacuum cleaners, in particular to a novel electric vacuum cleaner which uses paper bags and separates dust from inhaled air on the principle of a cyclone. Background technique

[0002] A general cyclone type electric vacuum cleaner is, for example, the vacuum cleaner shown in Japanese Patent Laid-Open No. 2002-17626. Compared with a disposable paper bag type electric vacuum cleaner, the dust storage part and the ventilation part are different, so that the odor of the gas is discharged. There is less, and the performance of the suction power drops less during use, and there is no need to discard the paper bag every time the dust is discarded. For economical reasons, the popularity of replacing the original paper bag-type electric vacuum cleaner tends to increase. However, such a cyclone type electric vacuum cleaner has a problem that dust is scattered and scattered when removing dust, which is not as good as a p...
