Abstract: A shaving apparatus having at least one cutting unit with an external cutting member and a rotatable internal cutting member each the external and internal cutting members having cooperating cutting edges forming bearing surfaces of a first bearing, and a second bearing with bearing surfaces. To minimize the friction between the cutting edges, a support device having visco-elastic properties is provided between the two bearings. During operation, the distance between the bearing surfaces of the first bearing adjusts to the distance between the bearing surfaces of the second bearing. During cutting of hairs, the support device behaves as a stiff element whereas during periods in which no hairs are cut, the support device behaves relatively soft so that the cutting gaps between the cutting edges are closed.
Abstract translation: 一种剃须装置，具有至少一个具有外部切割构件的切割单元和可旋转的内部切割构件，每个所述外部和内部切割构件具有形成第一轴承的支承表面的协作切割边缘和具有支承表面的第二轴承。 为了最小化切削刃之间的摩擦，在两个轴承之间提供具有粘弹性的支撑装置。 在操作期间，第一轴承的轴承表面之间的距离调节到第二轴承的支承表面之间的距离。 在切割毛发期间，支撑装置表现为刚性元件，而在没有毛发被切割的时段期间，支撑装置的行为相对较软，使得切割边缘之间的切割间隙被封闭。

Abstract: A surface cleaning device comprises a brush (B) that is curved at least partially around a center part (CP) of the surface cleaning device, a deformability of the brush (B) determining a deformability of an outer circumference of the surface cleaning device. The brush (B) has a rotation axis (A), which is curved at least partially around the center part (CP) of the surface cleaning device. The rotation axis (A) is parallel to the surface. The brush (B) may be a donut-shaped brush (B) fully around the center part (CP) of the surface cleaning device. The surface cleaning device may have an electrical motor (M) for driving the brush (B). The center part (CP) may comprise a container (DC) for collecting dirt swept from the surface by the brush (B). The center part (CP) may have an edge (E) for bending the brush (B), dirt being released from the brush (B) at an end of the edge (E) where the brush (B) is relaxed. The center part (CP) may have an upper rim (R) for keeping the brush (B) at its position. A length of brush fibers from the rotation axis (A) of the brush (B) is preferably at least about 0.4, and more preferably at least about 0.6, times a radius of an undeformable core of the surface cleaning device. The surface cleaning device may further comprise a fan for generating an air flow that does not exceed 6 1/s, preferably 3 1/s, and more preferably 1.5 1/s.

Abstract: A vacuum cleaner head has a base and a suction opening in the base. An array of flexible flaps protrudes from the base. The flexible flaps are configured to act on a surface to be cleaned. The flexible flaps are spaced from each other to allow the passage of detritus therebetween in a predefined arrangement. The predefined arrangement of the flexible flaps is configured to promote a non-linear flow path through the array of flexible flaps between an end of the base and the suction opening. A gap between first and second rows of flaps is substantially equal to or greater than a space between adjacent flexible flaps in each of the first and second rows.

IPC: A47L11/40
Abstract: A cleaning device for cleaning a surface is described. The cleaning device includes at least one cleaning element and a wetting system to supply a cleaning liquid to the at least one cleaning element. The wetting system is operable in one of at least one normal operation mode and a boost operation mode involving an increased supply rate of the cleaning liquid with respect to the at least one normal operation mode. During start-up of the cleaning device in a wet cleaning mode thereof, a start-up operation mode of the wetting system is determined to be one of the normal operation mode or the boost operation mode on the basis of assessment of an actual value of at least one parameter that is indicative of whether or not the at least one cleaning element is in a wet cleaning condition.

Abstract: In a vacuum cleaner nozzle (N) comprising one or more rear wheels (RW), a hinge (H3) is arranged to lift all one or more rear wheels (RW) from a floor (F) when a suction tube (ST) connected to the nozzle (N) is rotated around a longitudinal axis of the suction tube (ST), e.g. after the nozzle (N) has been rotated by more than 45° by means of a further hinge (H2) in order to position a relatively short side of the nozzle at the front of the nozzle in the nozzle's motion direction so that the nozzle is able to clean relatively small spaces that could not be entered if a relatively long side of the nozzle is at the front of the nozzle in the nozzle's motion direction. If the one or more rear wheels (RW) comprise at least two rear wheels, the hinge (H3) is arranged for simultaneously lifting the rear wheels (RW) from the floor (F). Preferably, the hinge (H3) is bi-stable, to which end the hinge (H3) may be provided with magnets (M1-2, M3-4) or a bi-stable spring (S) to fix the hinge (H3) either in a first position in which the one or more rear wheels (RW) are arranged to touch the floor (F), or in a second position in which the one or more rear wheels (RW) are arranged to be lifted from the floor (F). A vacuum cleaner advantageously comprises such a nozzle.

Abstract: The present application relates to a vacuum cleaner head (10). The vacuum cleaner head (10) includes a housing (40) having a vacuum extraction zone (49), and first and second rollers (20, 30) configured to locate against a surface to be cleaned (60). Each of the first and second rollers (20, 30) is able to pick-up detritus from the surface to be cleaned (60) when they rotate and move over the surface (60) and to carry detritus to the vacuum extraction area (49) in the housing (40). In accordance with the present invention, the first roller (20) is rotatable when moved along the surface to be cleaned (60) in a first direction and restricted from rotating when moved in an opposing second direction. The second roller (30) is rotatable when moved along the surface to be cleaned (60) in the second direction and restricted from rotating when moved in the first direction. The present application also relates to a vacuum cleaner comprising the vacuum cleaner head (10).
