ABSTRACT:
A small dust catcher includes a main tube and an inlet section. The inlet section is releasably connected to the main tube. The dust catcher further includes a filter assembly which is removably supported with an upper opening of the inlet section, with an upright positioning piece being located within a central opening of a partition wall. This uncomplicated arrangement makes it particularly easy to remove the filter assembly for cleaning or maintenance, while ensuring that the filter assembly is held securely in place during use. The dust catcher further includes a fan, a motor and a battery case, and a cover which covers the battery case. The fan, motor and battery case form a one piece assembly which can be disconnected from the main tube. This makes it easy to get at the fan, motor and battery case for maintenance. Preferably, the dust catcher simulates the appearance of a pen. Preferably, an elongated pin simulates the appearance of a pen clip and biases a switch button toward a released or off position.
