    Abstract: A nozzle for a fan assembly has an air inlet, an annular air outlet, and an interior passage for conveying air from the air inlet to the air outlet. The interior passage is located between an annular inner wall, and an outer wall extending about the inner wall. The inner wall at least partially defines a bore through which air from outside the nozzle is drawn by air emitted from the air outlet. The inner wall is eccentric with respect to the outer wall so that the cross-sectional area of the interior passage varies about the bore. The variation in the cross-sectional area of the interior passage can control the direction in which air is emitted from around the air outlet to reduce turbulence in the air flow generated by the fan assembly.

    CPC classification number: A45D20/10

    Abstract: Disclosed is a hair care appliance comprising a body, a fluid flow path extending through the body from a fluid inlet to a fluid outlet and a PCB extending about the fluid flow path. The PCB may be annular. The PCB may be isolated from the fluid flow path. The PCB may comprise a first layer and a second layer. The first layer may extend substantially continuously about the fluid flow path and the second layer may extend partially about the fluid flow path. The second layer may be adjacent the first layer and may be downstream of the first layer. The body may comprise a duct and the fluid flow path extends through the duct. The PCB may extend about the duct. The body may comprise a primary fluid flow path extending about the duct which may be in fluid communication with the PCB.

    Abstract: A self-righting cleaning appliance of the cylinder type comprises a separating apparatus for separating dirt from a dirt-bearing fluid flow, and a floor-engaging rolling assembly having a recess in which the separating apparatus is received. At least a portion of the separating apparatus is visible as a portion of the outer surface of the cleaning appliance when the separating apparatus is received in the recess, and the cleaning appliance is arranged so that it is urged to return to an upright position if it is tipped onto its side.

    Abstract translation: 圆柱型自动清洁器具包括用于从污物流体流中分离污物的分离装置，以及具有凹部的地板接合滚动组件，其中容纳分离装置。 当分离装置被容纳在凹部中时，分离装置的至少一部分可视为清洁器具的外表面的一部分，并且清洁器具被布置成使得如果它被推回到直立位置 被倾斜到它的一边。
