背景技术Background technique

目前市售的无叶型安全风扇，包括底座和设置在底座上的环形出风面罩，底座中设有以涡轮式风机为主的吸风组件；这种风扇的最大优点是由于摒除了传统电风扇所用的扇叶，从而无论对大人还是幼儿均具有极好的安全性。但是这种风扇也存在以下不足之处：为了避免庞大臃肿，采用较小直径的底座，所以限制了涡轮式风机的大小，为了保证足够的出风量，涡轮式风机的转速较高，一般达到每秒几百至上千转，导致噪音很大，且难以根除；另外，由于涡轮式风机的直径太小，虽然其转速很高，但是出风量仍然不能与传统风扇相比，吹风效果不佳。The current commercially available bladeless safety fan includes a base and an annular air outlet mask arranged on the base, and the base is provided with a suction assembly mainly consisting of a turbo fan; the biggest advantage of this fan is that it eliminates the traditional electric The fan blades used by the fan are extremely safe for both adults and children. However, this kind of fan also has the following disadvantages: in order to avoid bulkiness and bloat, the base with a smaller diameter is used, so the size of the turbo fan is limited. Hundreds to thousands of revolutions per second, resulting in a lot of noise, which is difficult to eradicate; in addition, because the diameter of the turbo fan is too small, although its speed is high, the air volume is still not comparable to that of traditional fans, and the blowing effect is not good.
