The dust laden air that is directed in the main body of dust collector 2 is separated into dust and the air that sucks dust separation dust collector portion 7.Separated dust is captured by dust separation dust collector portion 7.In addition, separated air further is inhaled into electric blower 8, is discharged from from main body of dust collector 2.

Thus and thus, electric dust collector 1 captures the dust that sucks from section port body 26 (26A, 26B).

The section port body 26 of this example (26A, 26B) when suction inlet main part 31 very when the detected object thing W, make 46 the past of rotary cleaning body side draught entrance 39 and bottom surface suction inlet 47 outstanding to the front lower place, thus the turning that cleaning detected object thing W and quilt are cleared away face.Thus, section port body 26 (26A, 26B) makes rotary cleaning body 46 arrive detected object thing W easily and clears away the turning of face with quilt, thereby can sweep dust effectively.

And, the section port body 26 of this example (26A, 26B) is compared with the section port body of the prior art that the lid that will cover the suction inlet front part is opened significantly, and the aperture area ground that need not change front side suction inlet 39 and bottom surface suction inlet 47 just can make rotary cleaning body 46 near detected object thing W with by the turning of cleaning face.

Thus and since when section port body 26 (26A, 26B) near detected object thing W with by the turning of cleaning face the time, can enough rotary cleaning bodies 46 aperture area of front side suction inlet 39 and bottom surface suction inlet 47 be diminished, therefore improve the flow velocity of suction air easily.

And the section port body 26 of this example (26A, 26B) makes rotary cleaning body 46 move to the back upper place of suction inlet main part 31 usually the time (when not contacting with detected object thing W), roughly is positioned at suction chamber 45.

In addition, in test section 53, used under the situation of detectors such as infrared ray sensor, just can be rotated the movement of cleaning body 46 in detected object thing W did not contact, becomes approaching state with section port body 26 stage.

Thus, section port body 26 (26A, 26B) not only can prevent that the user of electric dust collector 1 from unexpectedly contacting with rotary cleaning body 46, and can prevent that rotary cleaning body 46 from contacting the resistance that produces with lid housing 37.

And, even the user of electric dust collector 1 deliberately pushes test section 53, side draught entrance 39 and bottom surface suction inlet 47 are outstanding to make rotary cleaning body 46 in the past, section port body 26 (26A, 26B) is compared with the section port body of the prior art that the lid that covers the suction inlet front part is opened significantly, because the aperture area of front side suction inlet 39 and bottom surface suction inlet 47 does not change, therefore safe, also very desirable aspect health.

Therefore, if adopt electric dust collector 1 and the section port body 26 (26A, 26B) of this example, not only possess the rotary cleaning body 46 that can not touch easily security is improved, and can clear away the dust of the corner part of buildings such as wall limit effectively.

In addition, electric dust collector 1 of the present invention is not limited to horizontal electric dust collector, also can be the electric dust collector 1 of vertical, rod-type, hand-held or self-propelled etc.
