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.

Abstract translation: 小型除尘器包括主管和入口部分。 入口部分可释放地连接到主管。 除尘器还包括过滤器组件，该过滤器组件可移除地由入口部分的上部开口支撑，直立定位件位于分隔壁的中心开口内。 这种简单的布置使得特别容易去除用于清洁或维护的过滤器组件，同时确保过滤器组件在使用期间牢固地保持在适当位置。 除尘器还包括风扇，电动机和电池壳体以及覆盖电池壳体的盖子。 风扇，电机和电池盒形成一体式组件，可与主管断开连接。 这样可以方便地在风扇，电机和电池盒上进行维护。 优选地，除尘器模拟笔的外观。 优选地，细长针模拟笔夹的外观并将开关按钮朝向释放或关闭位置偏置。
