Description

一种无叶风扇
技术领域
本实用新型涉及一种风扇，具体涉及一种无叶风扇。
背景技术
传统的风扇均是利用叶片的高速旋转，带动空气流动，结构较为复杂，且风量较小。
针对传统风扇的缺陷，人们开发出了无叶风扇，其主要是利用电机及压缩装置将长压空气处理成高压空气，再由开设在风扇出风口（通常为风环上的细小缝隙）排出；这种风扇结构简单，操作方便，具有良好的发展前景。
然而，现有的无叶风扇，其出风角度不易调节，仅仅能够按照单一方向送风，送出风的利用率较低。
综上所述，开发一种能够随意调节角度的无叶风扇，已经成为业内关注的焦点。
发明内容
针对现有技术的不足，本实用新型的目的旨在于提供一种无叶风扇，其能够根据需要，随意转动风的输出角度。
为实现上述目的，本实用新型采用如下技术方案：
一种无叶风扇，包括位于其底部的底座、以及安装在下部且中空的下部支柱、活动安装在所述下部支柱上且中空的上部支柱、安装在所述上部支柱上且中空的支架、以及与所述支架枢装且内部置空的风环；所述下部支柱、上部支柱、支架及风环的内腔互相导通。
所述风环呈圆形，所述支架呈U形。
所述支架的U形两上端部内侧分别设置有枢轴，所述风环安装在所述枢轴上。
所述下部支柱与所述上部支柱连接处的外部，还套装有一可锁紧其二者的外扣。
所述下部支柱可转动的连接在所述底座上。
本实用新型所阐述的无叶风扇，其有益效果在于：
1、能够根据使用需要，随意的转动送风角度，送出风的利用率高；
2、结构简单，使用方便，有利于推广。
附图说明
图1为本实用新型一种无叶风扇的结构示意图；
图2为图1的A处放大视图。
具体实施方式
下面，结合附图以及具体实施方式，对本实用新型的无叶风扇做进一步描述，以便于更清楚的理解本实用新型所要求保护的技术思想。
如图1、2所示，为本实用新型的一种无叶风扇，包括底座1、下部支柱2、上部支柱3、支架4、风环5，其均为中空结构，下部支柱2连接在底座1上，并可沿其轴线转动，上部支柱3插装在下部支柱2内，可相对于下部支柱2上下滑动，支架4大体呈U形，其底端部插装在上部支柱3的上端，并可绕上部支柱3的轴线转动。风环5为圆形状，安装在支架4的U形内，具体的是，在支架4的U形两上端部内侧分别设置有向内延伸的枢轴41，风环5上预设与枢轴41匹配的安装孔位，使得风环5可绕枢轴41的轴线转动。
上述包括底座1、下部支柱2、上部支柱3、支架4、风环5的内部空腔互相导通；枢轴41为中空结构，用于导通风环5与支架4的内腔。
对于本领域的技术人员来说，可根据以上描述的技术方案以及构思，做出其它各种相应的改变以及变形，而所有的这些改变以及变形都应该属于本实用新型权利要求的保护范围之内。
