Definitions

• Cleaning device for cleaning a shaving head of a dry shaving apparatus with a housing, a holding device, a cleaning liquid container, a filter, a conveyor device which can be driven by a motor with a feed pipe to a cleaning trough and a liquid discharge from the cleaning trough to the cleaning liquid container.
• a cleaning device of the type mentioned is known from DE 44 02 238 C2.
• a nozzle is provided on a cleaning tub with a drawn-on cleaning liquid permeable porous hose part, which ensures that no dirt particles get into the cleaning liquid container. Due to the strong accumulation of dirt particles to be removed from the shaving head of a dry shaving apparatus, the hose part is clogged relatively quickly, so that cleaning liquid running out of the cleaning trough during the cleaning process cannot get into the cleaning liquid container. The result is an overflow of cleaning fluid from the cleaning device.
