Abstract: A dental cleaning device (1) is provided with a mouthpiece (6) and with a grip member (4) having a fluid channel (83, 76, 75, 67, 69, 70, 71, 93, 94) and having a fluid-flow control device (61) which is adjustable an actuating member (8), which is movable between different actuating positions to change the amount of fluid supplied to the mouthpiece (6) through the fluid channel (83, 76, 75, 67, 69, 70, 71, 93, 94), the grip member (4) is provided with activatable parts (83, 76, 75, 67, 72, 73, 74, 32, 94) for temporarily increasing the amount of fluid supplied to the mouthpiece (6) while the instantaneous actuating position of the actuating member (8) for the fluid-flow control device (61) is maintained.

Abstract: A dental-jet device (1) is provided comprising a grip member (4) and at least one mouthpiece having a tubular part (8) and a nozzle head (7) mounted on the tubular part (8) so as to be rotatable about an axis of rotation (15) and sealed relative to the tubular part (8) by a seal (21 ), which nozzle head has at least one central jet orifice (16) and a plurality of peripheral jet orifices (17), the tubular part (8) has a single tubular-part outlet (23) which communicates with its fluid channel (9) and which is off-centered from the axis of rotation (15), and the nozzle head (17) has only two nozzle-head inlets (24, 25), which are off-centered from the axis of rotation (15) and which are sealed from one another by means of a second seal (26) acting between the tubular part (8) and the nozzle head (7), one nozzle-head inlet (24) connecting the tubular-part outlet (23) to the central-jet orifice (16) in the central-jet position and the other nozzle-head inlet (25) connecting the tubular-part outlet (23) to the per

Abstract: In a shaving apparatus (1) comprising a housing (2) and a shaving head (10) with a shaving-head frame (12) and a foil frame (31) at least two helical pressure springs (57, 58) act between the two frames (12, 31) and are each arranged in a circumferentially closed duct (45, 46) provided in one (31) of the two frames (12, 31), which duct also accommodates a piston-like pressure member (47, 48) which projects from the relevant duct (45, 46) and bears against the other one (12) of the two frames (12,31).

Abstract: In a shaving apparatus (1) comprising a housing (2) and a shaving head (10) with a shaving-head frame (12) and a foil frame (31) which can be locked thereto the two transverse side walls (15, 16) of the shaving-head frame (12) are extended relative to the two transverse side walls (35, 36) of the foil frame (31) in a direction towards the housing (2) of the shaving apparatus (1) by a wall extension (61, 62), and on each wall extension (61, 62) a latch (65, 66), which extends substantially in the direction of the wall extension (61, 62), is supported so as to be movable transversely of the wall extension (61, 62) against spring force to provide positive locking of the foil frame (31) in the shaving-head frame (12).

Abstract: In a dry-shaving apparatus comprising a slidable shutter (3) for optionally covering or exposing a shear foil (9) of the dry-shaving apparatus, which shear foil is mounted in a shaving-head frame which is detachably secured to a basic apparatus (1) of the dry shaver, said shutter having a first latched position which is locked by a latching means (12, 13, 14, 15) and in which the circuit of the motor for driving the dry-shaving apparatus is closed by the shutter when the shutter exposes the shear foil to allow shaving, the shutter can be slid away from the shear foil completely onto the basic apparatus, the shutter having a further latched position in which it is locked by means of a latch (12, 13, 23, 24) and in which the shear foil and the shaving-head frame are exposed by the shutter and the motor circuit is interrupted by means of the shutter.

Abstract: A dry-shaving apparatus is provided comprising a shaving-head frame (2), which can be placed on a basic apparatus (1), which carries a shear foil (7), and which is detachably secured to the basic apparatus by means of at least one resilient latch (12), and at least one slidable shutter (3) for optionally covering or exposing the shear foil wherein the shutter is movable from a position on the basic apparatus in which it exposes the shaving-head frame and the shear foil to a position on the shaving-head frame, and wherein movement of the latch to detach the shaving-head frame from the basic apparatus is blocked by the shutter when the shutter has been moved at least partly out of the position in which it exposes the shaving-head frame and the shear foil.
