(EN) The invention relates to an electric vacuum cleaner. In the vacuum cleaner main body 1 with electric blowers 5A, 5B housed therein, a common dust collecting chamber 4 is provided which communicates with a suction side of each of the electric blowers 5A, 5B. A controlling means 6 is provided which is capable of controlling the driving of the electric blowers 5A, 5B independently. Check valve units 43A, 43B for preventing air from flowing backward to the dust collecting chamber 4 side are arranged in accordance with the electric blowers 5A, 5B. Even if either of the electric blowers 5A, 5B is driven, the check valve unit 43A, 43B prevents air from being sucked into the dust collecting chamber 4 side from the stopping electric blower 5B, 5A, and suction force can be secured.
(ZH) 本发明涉及一种电动真空吸尘器，在真空吸尘器主体(1)的内部容纳有电动鼓风机(5A，5B)，与每个所述电动鼓风机(5A，5B)吸气侧相通的公共集尘室(4)。设有可独立控制电动鼓风机(5A，5B)的控制装置。用于防止空气回流到所述集尘室(4)一侧的单向阀单元(43A，43B)根据电动鼓风机(5A，5B)而设。即使驱动任一电动鼓风机(5A，5B)，所述单向阀单元(43A，43B)也可防止空气从未驱动的电动鼓风机(5B，5A)吸入所述集尘室(4)一侧，且可以保障吸入功率。
