Shaver arrangement with suction mechanism

摘要

The razor suction arrangement has a filtering device (3) with a level indicator (6) and a replaceable bag (4). The filter is mounted in a removable drawer (5) and can be closed by a valve (7). The level indicator is driven by a sensor (9) which detects the level in the filter. The level indicator is a visual indicator, e.g. a window or light emitting diode. The sensor can be a flow sensor or a detector of an electrical parameter, e.g. for measuring the amplitude of the motor current. It can be a light barrier on the filter.
