Abstract: A fan for generating an air current includes a body having an air inlet, and a nozzle connected to the body. The nozzle includes an interior passage and an air outlet from which the air flow is emitted from the fan. The interior passage extends about an opening or bore through which air from outside the nozzle is drawn by air emitted from the air outlet. The body includes a duct having a first end defining an air inlet of the duct and a second end located opposite to the first end and defining an air outlet of the duct, an impeller located within the duct for drawing the air flow through the duct, and a motor for driving the impeller. The second end of the duct protrudes from the body into the interior passage of the nozzle.

Abstract translation: 用于产生气流的风扇包括具有空气入口的主体和连接到主体的喷嘴。 喷嘴包括内部通道和空气出口，空气流从风扇排出。 内部通道围绕开口或孔延伸，从喷嘴外部的空气通过空气从空气出口排出的空气被吸入。 主体包括管道，其具有限定管道的空气入口的第一端和与第一端相对定位并限定管道的空气出口的第二端，设置在管道内的叶轮，用于抽吸气流通过管道， 以及用于驱动叶轮的马达。 管道的第二端从主体突出到喷嘴的内部通道中。
