Then, when under the user of electric dust collector 1 is gripping the state of grip part 23, making at hand operation pipe 22 and prolonging pipe 25 front-rear reciprocation movements, section port body 26 (26A, 26B) is back and forth walking of front and back on quilt cleaning face, will be sucked together in the section port body 26 (26A, 26B) by the dust and the air of cleaning face.
And, when section port body 26 (26A, 26B) is walked on the cleaning face on ground etc. (when detected object thing W does not contact with test section 53), make rotary cleaning body 46 be positioned at the mobile terminal (Fig. 4) of back upper place one side.
Thus, the bristle 52 of rotary cleaning body 46 has been swept by cleaning face.The dust of having been swept by bristle 52 sucks with air the past side draught inlet 39 and bottom surface suction inlet 47, is inhaled in the section port body 26 (26A, 26B).
And,, make rotary cleaning body 46 be positioned at the mobile terminal (Fig. 5) of front lower place one side when section port body 26 (26A, 26B) when having contacted (when detected object thing W has contacted with test section 53) with detected object thing W such as wall, furniture.
Thus, the bristle 52 of rotary cleaning body 46 swept detected object thing W with by the turning of cleaning face, the dust of having been swept by bristle 52 is drawn in the section port body 26 (26A, 26B) with air side draught inlet 39 and 47 suctions of bottom surface suction inlet in the past.
And, section port body 26 (26A, 26B) is positioned on the mobile terminal of front lower place one side the end of a side (Fig. 6 is owing to be expressed as the left side with upward view) of rotary cleaning body 46 when a side of having only its width (for example having only the right side) when having contacted with detected object thing W such as wall or furniture (when for example detected object thing W has contacted with the test section 53 on right side).
Thus, rotary cleaning body 46 only makes the nearly detected object thing of the side joint W that has contacted with detected object thing W, swept detected object thing W with by the turning of cleaning face.
Be inhaled into dust laden air in the section port body 26 (26A, 26B) successively through prolonging pipe 25, at hand after operation pipe 22 and the dust collection hose 21, being directed in the main body of dust collector 2.
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 inlet 39 and bottom surface suction inlet 47 outstanding to the front lower place, thus the turning of cleaning detected object thing W and quilt cleaning 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, used in test section 53 under the situation of detectors such as infrared ray sensor, the stage that does not contact, becomes approaching state at detected object thing W with section port body 26 just can be rotated moving of cleaning body 46.
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 inlet 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 the 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.
