Description

一种无叶片风扇的喷嘴
技术领域
本发明属于风扇技术领域，具体的涉及一种无叶片风扇的喷嘴。
背景技术
无叶片风扇一般都是向一侧出风的，如专利申请号：200810177844.8公开了一种无叶片风扇，这种无叶片风扇的喷嘴为一圈环形的壳体，壳体内部设置有进风通道，壳体上还设置有一圈与通道相通的开口，使用时，气流通入壳体中，进入进风通道内，再经由开口处吹出。这种喷嘴的开口一般只能朝向一侧。风力能够影响的范围有限，在一些人比较多而且分散的时候，在风扇的正反两面都有人时就不能满足需求。
发明内容
本发明针对现有技术中的不足，提供了一种无叶片风扇的喷嘴，能够向两侧同时吹风，满足在风扇的正反两面都有人时的需求。
为了解决上述技术问题，本发明通过下述技术方案得以解决：一种无叶片风扇的喷嘴，包括一圈环形的壳体，所述壳体内部设置有进风通道，所述壳体上设置有与所述进风通道相通的开口，还包括一圈环形的导流板，所述导流板位于所述壳体的内圈，所述导流板固定在所述壳体上，所述导流板的外圈与所述壳体的内圈之间形成具有两个相对设置的出风口的出风通道，所述开口连通所述出风通道和所述进风通道。气流从进风通道吹出开口后，进入出风通道，然后从两个相对设置的出风口中吹出，这样气流能够同时从喷嘴的正反两面吹出，尤其适合在一些风扇正反两面都有人时候的场合。
上述技术方案中，具体的一种导流板与壳体的固定方式为，还包括连接件，所述连接件一端固定在所述壳体上，所述连接件的另一端固定在所述导流板上。这里的连接件可以是板或者杆。
上述技术方案中，另一种导流板与壳体的固定方式为，还包括螺栓和螺母，所述螺栓穿过所述壳体和所述导流板以后与所述螺母相螺接。这种方式导流板可以拆卸。
上述技术方案中，优选的所述壳体的内圈位于所述开口处两端的直径最小，向壳体两端逐渐变大。这样有利于从出风口吹出的气流扩散。
本发明的有益效果是：气流从进风通道吹出开口后，进入出风通道，然后从两个相对设置的出风口中吹出，这样气流能够同时从喷嘴的正反两面吹出，尤其适合在一些风扇正反两面都有人时候的场合。
附图说明
图1为本发明第一个实施例的立体示意图。
图2为本发明第一个实施例的平面示意图。
图3为图2的局部放大图。
图4为本发明第二个实施例的示意图。
图5为本发明第三个实施例的示意图。
具体实施方式
下面结合附图与具体实施方式对本发明作进一步详细描述：
实施例1，参见图1至图3，一种无叶片风扇的喷嘴，包括一圈环形的壳体1、环形的导流板2和连接件4，壳体1内部成型有进风通道11，壳体1的下部设置有与进风通道11相通的开口12。壳体1的内圈位于开口12处两端的直径最小，向壳体1两端逐渐变大，呈一个“v”字形。壳体1内圈的中部成型有与进风通道11相通的一圈环形的开口12，导流板2位于壳体1的内圈，导流板2的外圈与壳体1的内圈之间形成具有两个相对设置的出风口211、212的出风通道21，开口12连通出风通道21和进风通道11。导流板2的外圈由两个圆台面22、23和连接这两个圆台面22、23的圆弧过渡面24组成，其中圆弧过渡面24位于开口12正对处，保证从开口12吹出的气流平缓过渡；圆台面22、23与位于开口12两侧的壳体1内圈分别平行，保证出风通道21的宽度各处一致，保证气流的顺畅。
本实施例采用杆件作为连接件4，实现导流板2与壳体1之间的连接。杆件一端固定在进风通道11内壁上，杆件的另一端穿过开口12后固定在导流板2的圆弧过渡面24上。
实施例2，参见图4，本实施例采用板件作为连接件4，实现导流板2与壳体1之间的连接，板件两端分别与壳体1的内圈与圆台面22、23相固定，其余同结构实施例1，这里不再赘述。这种连接方式，导流板2的两端都得到固定，导流板2的连接更加可靠。
实施例3，参见图5，本实施例采用螺栓51和螺母52实现导流板2与壳体1之间的连接，螺栓51穿过壳体1和导流板2以后与螺母52相螺接，其余结构同实施例1，这里不再赘述。这种方式，通过旋开螺母52，可以将导流板2拆卸下来。
