<P>PROBLEM TO BE SOLVED: To provide an air suction and jetting device that is sanitary and can collect dust regardless of an amount of dust. <P>SOLUTION: The air suction and jetting device includes: a suction chamber 6 to which a suction hose (not shown) of a vacuum cleaner (not shown) is connected so that suction force acts; a suction fan 5 configured to rotated by the air sucked through a suction opening 2 provided in the suction chamber 6; a jet fan 10 provided in a jet chamber 11 from which the air introduced from the outside is jetted toward a jet opening 7, and configured to be rotated in conjunction with the suction fan 5; a dust detector 18 for detecting dust passing through a suction flow path 3a communicating the suction opening 2 with the suction chamber 6; and a jet controller 19 for controlling air jetting from the jet opening 7 based on dust detection information detected by the dust detector 18. The air suction and jetting device is configured such that, for example, when there is a large amount of dust, the device stops jetting air to concentrate on sucking dust while preventing dust from being blown up, and meanwhile, with a small amount of dust, the device starts jetting air to blow up dust for suction again, thus achieving smooth collection of dust. <P>COPYRIGHT: (C)2013,JPO&INPIT |
