Abstract

为了有效的拓展吊扇的功能，我们提供了一种双变速吊扇，该双变速吊扇是将吊扇扇叶设计成伸缩扇叶，伸缩扇叶由伸缩叶片及伸缩弹簧构成，伸缩弹簧装置在伸缩叶片里。随着电扇转速的变化扇叶的伸长缩短随之变化，从而达到双变速其风力成倍增加。

Description

双变速吊扇
技术领域
本发明是一种用于电风扇的设备，就是一种双变速吊扇。
背景技术
吊扇变速靠挡位，如果将扇叶设计成伸缩扇叶，随着电扇转速的变化扇叶的伸长缩短随之变化，就达到双变速其风力成倍增加效果显著。
发明内容
该双变速吊扇是将吊扇扇叶设计成伸缩扇叶，伸缩扇叶由伸缩叶片及伸缩弹簧构成，伸缩弹簧装置在伸缩叶片里。随着电扇转速的变化扇叶的伸长缩短随之变化，从而达到双变速其风力成倍增加，如图所示。本发明的有益效果是结构简单，方便使用，效果好。
附图说明
图1为双变速吊扇的结构示意图：
其中1是伸缩叶片，2是伸缩弹簧。
具体实施方式
图1中，双变速吊扇是将吊扇扇叶设计成伸缩扇叶，伸缩扇叶由伸缩叶片及伸缩弹簧构成，伸缩弹簧装置在伸缩叶片里。随着电扇转速的变化扇叶的伸长缩短随之变化，从而达到双变速其风力成倍增加。
