Abstract: A nozzle for a fan assembly includes an air inlet, a plurality of air outlets, and an annular casing having an annular inner wall defining a bore through which air from outside the nozzle is drawn by air emitted from the air outlets and an outer wall extending about the inner wall. The annular casing includes an air passage for conveying air to the air outlets. The air passage has an inlet section located between the inner wall and the outer wall and extending about the bore of the nozzle, and a plurality of outlet sections each extending across the bore for conveying air to a respective air outlet. To achieve an even air pressure at each end of each of the outlet sections, the inlet section of the air passage is arranged to convey air to each end of each of the outlet sections.

Abstract translation: 用于风扇组件的喷嘴包括空气入口，多个空气出口和环形壳体，所述环形壳体具有限定孔的环形内壁，通过所述孔从所述喷嘴外部的空气从所述空气出口排出的空气被吸入，并且外壁延伸 关于内墙。 环形壳体包括用于将空气输送到空气出口的空气通道。 空气通道具有位于内壁和外壁之间并且围绕喷嘴的孔延伸的入口部分，以及多个出口部分，每个出口部分跨过孔延伸以将空气输送到相应的空气出口。 为了在每个出口部分的每个端部处实现均匀的空气压力，空气通道的入口部分布置成将空气输送到每个出口部分的每个端部。

Abstract: A fan includes a base and a nozzle mounted on the base. The base includes an impeller and a motor for driving the impeller to generate an air flow. The nozzle includes an air inlet, an air outlet, and an annular casing which defines a bore through which air from outside the fan is drawn by air emitted from the air outlet. An ionizer is located within the bore of the nozzle for treating the air drawn through the bore.
