技术领域 FIELD

[0001] 本实用新型是一种电扇,特别是涉及一种出风效果好的无叶风扇。 [0001] The present invention is a fan, more particularly to a good effect of wind bladeless fan.

背景技术 Background technique

[0002]目前,风扇大部分都是采用的有叶风扇的形式,通过切割驱动空气按指定的方向进行移动,形成风力。 [0002] Currently, most are employed are in the form of a fan blade of a fan, the air moves the drive by cutting the specified direction, the wind is formed. 而这个形式的风扇,由于相对有危险性、噪声较大的弊端,慢慢被使用者所摒弃,现在市场上的安全可靠、噪声较小的无叶风扇慢慢开始受到消费者的欢迎,无叶风扇采用的是通过抽取空气进行喷射,带动空气进行喷射形成风力。 And this form of fan, due to the relatively dangerous, noisy drawbacks, slowly being abandoned by the user, is now safe and reliable on the market, the less noise bladeless fan slowly began to be popular with consumers, no leaf fan is used by air injection extraction, wind driven air jet is formed. 但是,现有的无叶风扇都是采用扩散式的、柯恩达表面的出风面,这也导致了风力有一个明显的扩散,风力可吹及的有效范围较小,空气从柯恩达表面吹过时,会有较大的摩擦损耗,风力较小。 However, conventional non-leaf fan are based on diffusion, the outlet side of the Coanda surface, which has also led to a significant diffusion of the wind, the wind can blow and small effective range, the air from the Coanda blowing the surface, have a greater friction loss, less wind.

[0003] 中国专利授权公告号:CN101825105B,公开了一种风扇组件,风扇组件包括安装在基部上的喷嘴,所述基部包括外壳体;容纳在外壳体内的叶轮机罩,叶轮机罩具有空气入口和空气出口,位于叶轮机罩的叶轮和驱动叶轮以产生穿过叶轮机罩的气流的马达。 [0003] Chinese Patent Publication No. Authorization: CN101825105B, discloses a fan assembly, the fan assembly comprising a nozzle mounted on the base, the base comprising an outer housing; an impeller housed in the housing body of the hood, the hood having an air inlet of the impeller and an air outlet, an impeller located in the impeller and hood motor driving the impeller to create the air flow through the turbine shroud. 喷嘴包括用来从叶轮机罩的空气出口接受气流的内部通道和嘴部,气流通过嘴部从风扇组件射出,其中挠性密封件位于所述的外壳体和所述叶轮机罩之间。 The nozzle includes an internal passage for receiving the air flow from the air outlet and the nozzle portion of the turbine shroud, the air flow emitted from the fan assembly through the mouth portion, wherein the flexible seal member positioned between said outer housing and said impeller housing. 这种风扇组件的主要核心是在外壳体和叶轮机罩之间安装密封件,阻止空气沿着在外壳体和叶轮机罩之间延伸的路径返回到所述空气入口,迫使叶轮产生的受压气流通过叶轮机罩输出并进入喷嘴。 The main core of this fan assembly is mounted between the seal housing and the turbine outer housing, to prevent air returns along a path extending between the outer housing and the turbine shroud to the air inlet, forcing the compression impellers the cover and into the nozzle output stream through turbine. 但是这种结构在外壳体和叶轮机罩之间依然有气流,而在气流经过外圈与叶轮机罩接触的位置,此处因为制造的需要,形状结构比较复杂,气流容易在此处形成紊流,从而影响出风效果。 However, this configuration still has the air flow between the outer housing and the impeller housing, and the position of gas flow through the turbine shroud and the outer contact, where because of the need, the shape of the structure for producing complex, turbulent air flow is easily formed here flow, thus affecting the effect of the wind.
