摘要： An environmental control unit comprises a housing, a vacuum cleaner, a filtration unit, and a blower. The vacuum cleaner is positioned in the housing and is configured to receive a tool contaminant stream produced by at least one tool. The vacuum cleaner filters particulate matter from the tool contaminant stream, thereby producing a filtered air stream. The filtration unit is also positioned within the housing and comprises at least one filter. The blower is positioned within the housing downstream of the filtration unit. The blower is configured to create negative air pressure within the second compartment to draw an area contaminant stream from an exterior of the environmental control unit into the housing. A second blower may also be present. The blower draws the filtered air stream and the area contaminant stream through the at least one filter in the filtration unit to produce a filtered mixture stream.

摘要： A cleaner including a body including a body exhaust vent; a filter installable inside the body; and a fan motor device including a rotatable impeller to generate a suction force inside the body, a motor to rotate the impeller, and a diffuser device including a radiating diffuser extending in a radial direction from a rotational axis of the impeller, and an axial diffuser extending from the radiating diffuser. The fan motor device is configured so that, with the filter installed inside the body, rotation of the impeller by the power provided by the motor causes air to pass through the fan motor device and be discharged from the impeller, and then guided by the radiating diffuser in the radial direction from the rotational axis of the impeller, and then guided by the axial diffuser to the filter to be filtered, and then discharged through the body exhaust vent.

摘要： An electric powered work machine according to one aspect of the present disclosure includes a first and a second digital filters, a control sound source, an error sensor, and a characteristics adjustor. The first digital filter includes a series of taps and generates a control signal. The control sound source produces an artificial noise in accordance with the control signal. The error sensor converts a synthesized sound of the artificial noise and a target noise at a canceling location to an error signal. The second digital filter includes N taps and generates a filtered reference signal. The characteristics adjustor uses the error signal and the filtered reference signal to adjust a coefficient of each tap of M taps in the series of taps. Each of M and N is a positive integer satisfying M

摘要： A dirt separator that includes an inlet; an outer wall defining a first dirt collection chamber of a first separation stage; an inner wall defining a second dirt collection chamber of a second separation stage; at least one rib extending from the inner wall into the second collection chamber; and a closure member hingedly connected to the dirt separator and movable between a closed position for sealing open ends of both the first and second dirt collection chambers and an open position for escape of dirt from the open ends. The closure member comprises a seal for sealing against the inner wall when the closure member is in the closed position, and the at least one rib has an end edge that is inclined such that the seal rides along the end edge and onto the inner wall as the closure member is closed.

摘要： A vacuum cleaner including a debris collection container having an outer perimeter and a lid removably coupled to the debris collection container. The lid has a periphery that extends along the outer perimeter of the debris collection container. The vacuum further includes a suction source coupled to the lid and removable from the debris collection container with the lid. The suction source includes a motor and an impeller driven by the motor. The vacuum cleaner further includes an exhaust passageway downstream from the suction source for discharging an airflow from the debris collection container. The exhaust passageway extends radially outward from the impeller and toward the periphery of the lid. The vacuum cleaner further includes an exhaust outlet port in communication with the exhaust passageway. The exhaust outlet port extends along a majority of the periphery of the lid.
