Description

一种无叶双头风扇
技术领域
本发明属于电风扇结构设计技术领域，具体涉及一种无叶风扇。
背景技术
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。
发明内容
本发明的目的是提供一种噪音较小且出风量较大的无叶双头风扇。
实现本发明目的的技术方案是：一种无叶双头风扇，包括吸风组件、两个出风面罩和电冷片；各出风面罩包括面板和背板，面板上设有出风狭孔，背板中心处设有安装孔，两个出风面罩的背板正对并邻接设置；面板和背板之间设有导风通道；吸风组件包括壳体、设置在壳体中的吸风机、设置在壳体中的第一风道和第二风道；壳体的中部设有作为进风孔的网孔板，壳体的左端设有第一风道出口，壳体的右端设有第二风道出口；壳体的两端设置在相应一个背板的安装孔中，第一风道出口与左侧出风面罩的导风通道连通，第二风道出口与右侧出风面罩的导风通道连通；电冷片设置在壳体中，位于两背板之间且邻接网孔板设置；吸风机包括双头电机和两个吸风扇轮，双头电机转动时，空气从壳体中部的进风孔中进入，经相应一个吸风扇轮后，进入到第一风道和第二风道中；各出风狭孔的形状是弧线状，并在各出风面罩的正面排列成环状。
本发明把吸风组件设置在出风面罩的背面中心处，由于出风面罩与传统无叶风扇的底座相比，直径要大上好几倍，所以本发明可以选用扇叶较大的吸风机，无需太高转速即可实现很好的吹风效果；从而具有噪音较小且出风量较大的优点。本发明和传统无叶风扇一样，扇叶内置，外面看不到，也是从孔径很小的网孔板处吸风，从很小的出风狭孔中出风，儿童的手指插不进去，所以还具有较好的安全性。
附图说明
图1是本发明的一种结构示意图。
具体实施方式
（实施例1）
本实施例是一种无叶双头风扇，见图1所示，包括吸风组件1和两个出风面罩2；各出风面罩包括面板21和背板22，面板上设有出风狭孔211，背板中心处设有安装孔，面板和背板之间设有导风通道23；吸风组件包括壳体11、设置在壳体中的吸风机12、设置在壳体中的第一风道13和第二风道14；壳体的中部设有作为进风孔的网孔板15，壳体的左端设有第一风道出口131，壳体的右端设有第二风道出口141；壳体的两端设置在相应一个背板的安装孔中，第一风道出口与左侧出风面罩的导风通道连通，第二风道出口与右侧出风面罩的导风通道连通。
各出风狭孔的形状是弧线状，并在各出风面罩的正面排列成环状。
吸风机包括双头电机121和两个吸风扇轮122，双头电机转动时，空气从壳体中部的进风孔中进入，经相应一个吸风扇轮后，进入到第一风道和第二风道中。
本实施例还包括电冷片3，电冷片设置在壳体中，位于两背板之间且邻接网孔板设置。
显然，本发明的上述实施例仅仅是为清楚地说明本发明所作的举例，而并非是对本发明的实施方式的限定。对于所属领域的普通技术人员来说，在上述说明的基础上还可以做出其它不同形式的变化或变动。这里无需也无法对所有的实施方式予以穷举。而这些属于本发明的实质精神所引伸出的显而易见的变化或变动仍属于本发明的保护范围。
