Abstract A dampening unit to reduce dust emission from the sweeper bag for an electrically operated vacuum sweeper, said unit adapted for disposition around the sweeper bag, and comprising an external skeletal network of tubular members depending and connected to a water container located at the top of the sweeper bag, the first of such tubular members being a series of horizontally disposed tubular rings aligned parallel to one another in a succession of imaginary planes intersecting at spaced intervals the central longitudinal and vertical axis of the sweeper bag; the second set of such tubular members being vertically depending tubular connections each of which connect the water container with a respective horizontal tubular member; a third set of finely perforated members which depend vertically downwardly from the horizontal tubular members to carry and disperse water on the sweeper bag; through which tubular connections water placed in the water container can seep downwardly in a controlled manner into the horizontal tubular members and thence into the vertically disposed perforated tubular members to reach the fabric material of the sweeper bag in order to dampen it.
A dampening unit for a sweeper for fitting over a vertically extending sweeper bag for an electrical vacuum sweeper bag comprising a: 1. a water container affixed to the top of the sweeper bag; 2. vertically depending tubes extending from the water container and surrounding the outer periphery of the sweeper bag; 3. a series of horizontal circular tubular members connected to the vertically extending tubular members by internal chambers which horizontal tubular members extend around the outer periphery of the sweeper bag; 4. vertically depending perforated tubes extending from the horizontal tubular members and venting into the outer periphery of the sweeper bag.
