    • A cyclonic portable vacuum cleaner/dust collector has a cyclonic chamber and a filter chamber. The filter chamber contains a filter cartridge with a hollow core positioned over the discharge opening of a motor plate that closes the filter chamber. A vacuum blower is mounted on the motor plate, with an intake tube at the discharge opening of the motor plate. An annular pulse-cleaning plate is positioned over an associated annular opening that surrounds the motor plate discharge opening and has an open center that slides up and down on the intake tube of the vacuum blower. A bail handle or lever extends from the pulse-cleaning plate to a handle portion outside the cover or shroud. The handle is pushed down to lift the pulsing plate to provide a reverse pressure air pulse to the filter to blast off accumulated dust. An anti-deflagration screen may be present at the center of the motor plate.
    • 旋风便携式吸尘器/集尘器具有旋风室和过滤室。 过滤室包含具有中空芯的过滤器滤芯,该中空芯位于关闭过滤室的马达板的排放口上方。 真空鼓风机安装在马达板上,进气管位于马达板的排放口。 环形脉冲清洁板位于围绕电动机板排出口的相关联的环形开口上方,并且具有在真空鼓风机的进气管上上下滑动的打开中心。 保释手柄或杠杆从脉冲清洁板延伸到盖或护罩外部的手柄部分。 手柄被推下以抬起脉冲板,以向过滤器提供反向压力空气脉冲以吹出积聚的灰尘。 在电动机板的中心可能存在防爆燃烧屏。
