Bench top dust collector
First Claim
1. A self-contained portable device for collecting dust particulate from dental appliances or the like comprising:
- a housing having a front, a rear, a top, a bottom, and at least partially open sides, the open sides having openings of sufficient size to receive an operator'"'"'s hands therethrough;
a hollow work chamber disposed at the front of the housing;
a base plate at the bottom of the hollow work chamber;
a vacuum duct in the base plate;
vacuum means fluidly connected to the vacuum duct to draw a vacuum at the vacuum duct in the base plate;
a filter bag disposed within the housing for collecting and containing particulate drawn from the vacuum duct;
light means to illuminate the work chamber;
sensor means for detecting the presence of the operator'"'"'s hands within the hollow work chamber, the sensor means sending an electrical signal responsive to the presence of the operator'"'"'s hands in the work chamber;
means responsive to the electrical signal to energize the light and the vacuum means;
whereby when the operators hands are inserted into the chamber, the sensor means detects their presence, energizing the light and vacuum means, thus drawing a vacuum at the vacuum duct to remove dust particulate from the work chamber.

Abstract
A self-contained portable device for collecting dust and other particulate matter or the like. There is a housing with partially open sides sufficiently large to allow the entrance of an operator'"'"'s hands. A sensor is activated when the operator'"'"'s hands are placed within the device. The sensor activates the vacuum motor and light source so that the work area is illuminated and particulate matter and dust can be drawn away from the work area. A removable and disposable filter bag collects the dust particles and can be disposed of when full. The operator does not come in contact with any contaminated dust or particulate matter in disposing of the filter bag.

9. A self-contained portable device for collecting dust and other particulate matter or the like comprising:
-
a housing having a front, a rear, a top, a bottom, and partially open sides sufficiently large to allow an operator'"'"'s hands to pass therethrough; a hollow work chamber defined by the front, rear, top, bottom, and sides wherein the operator can work on dental appliances; a duct at the bottom of the hollow work chamber; a disposable filter bag within the housing, the duct in fluid communication with the filter bag; means for creating a vacuum at the duct for drawing the dust and particulate matter from the hollow work chamber to the filter bag where it is contained; sensor means for detecting the presence of the operator'"'"'s hands in the work chamber, the sensor means operatively connected to the means for creating a vacuum, the means for creating a vacuum being automatically activated when the operator'"'"'s hands are placed in the work chamber. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
