Title: SHAVING UNIT HAVING CUTTING UNITS WITH A FLUSH HOLE FOR CLEANING A HAIR COLLECTION CHAMBER
Abstract:
The invention relates to a shaving unit for a shaving apparatus, comprising at least a first cutting unit (410a) and a second cutting unit (410b), wherein said first and second cutting units respectively comprise a first and a second external cutting member (460a), (460b) having a plurality of hair entry openings and a first and a second internal cutting member (480a), (480b) which is rotatable relative to, respectively, the first and the second external cutting member about, respectively, a first and a second axis of rotation (406a), (406b). The first and second internal cutting members are connected to a transmission unit via, respectively, a first and a second drive (spindle (476a), (476b). The cutting units each comprise a housing (420a) having a bottom wall (424a) which comprises an opening (425a) which is in fluid communication with a hair collection chamber (427a) in the housing. In each cutting unit a sealing structure (465a) is provided between the opening and the hair collection chamber, said sealing structure being configured and arranged to prevent cut hairs from escaping from the hair collection chamber via the opening and to allow water to flush via the opening to the hair collection chamber.
