Abstract
Abstract An electric shaving apparatus is provided which comprises a housing, a switch for activating switching cycles in which the apparatus is switched on and off, a holder for at least one external shaving member with hair-entry apertures, and an internal shaving member adapted to be driven by the external shaving member, the housing having a collecting space for shaving particles, which collecting space has a closing member with a locking mechanism, which locking mechanism comprises an actuating member, the apparatus comprising means for counting the number of switching cycles and a signalling device for signalling that cleaning of the collecting space is desirable in response to a predetermined or selected number of switching cycles. The signalling device comprises a light-emitting element in combination with the actuating member.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
141 words
An electric shaving apparatus having a housing, a switch for activating a switching cycle in which the apparatus is switched on and off, a holder for at least one external shaving member with hair-entry apertures, and an internal shaving member, the housing having a collecting space for shaving particles, which collecting space has a closing member with a locking mechanism having an actuating member for locking and unlocking the closing member, the apparatus comprising detection means for determining that cleaning of the collecting space is desirable, and a signalling device for signalling that cleaning of the collecting space is desirable, said detecting means being effective to activate said signalling means responsive to a selected or predetermined indication of soiling of the collecting space, wherein the signalling device comprises a light-emitting element in combination with the actuating member of said locking mechanism.
Claim 2
Dependent Claim
141 words
An electric shaving apparatus having a housing, a switch for activating a switching cycle in which the apparatus is switched on and off, a holder for at least one external shaving member with hair-entry apertures, and an internal shaving member, the housing having a collecting space for shaving particles, which collecting space has a closing member with a locking mechanism having an actuating member for locking and unlocking the closing member, the apparatus comprising detection means for determining that cleaning of the collecting space is desirable, and a signalling device for signalling that cleaning of the collecting space is desirable, said detecting means being effective to activate said signalling means responsive to a selected or predetermined indication of soiling of the collecting space, wherein the signalling device comprises a light-emitting element in combination with the actuating member of said locking mechanism.
