Abstract

一种电风扇的导风机构,由于风轮旋钮仅通过弹 性调整环即可调控导风轮的转速,使电扇实现从“慢” 到“快”的无级调速。本实用新型具有零件少,装配简 单,结构合理,调速可靠,成本不高等优点,可广泛用 于各种尺寸的座钟电扇或鸿运扇。

Description

本实用新型属于转页式电风扇的风轮调速装置。
目前,国内流行的电风扇导风机构较为复杂,零件较多,如申请号为86206086的专利申请所公开的“转页式电风扇导风格栅调速装置”,就包括了导风轮、导风轮衬套、导风轮盖、螺钉等部件,并且导风轮盖需用螺钉固定。这种调速装置(也称导风机构)由于结构复杂,不能可靠地进行调速,故一般采用“停”或“转”的形式工作。
本实用新型的目的,是提供一种新的导风机构,无需使用导风轮盖,节省了零部件,调速装置变得结构简单,使电扇实现从“慢”到“快”的无级调速。
该导风机构由导风轮、嵌件、衬套、调速环、轴挡件、风轮旋钮等构成。导风轮、衬套及嵌件可依次同轴紧密安装;也可将导风轮与衬套注塑成一整体,再与嵌件同轴安装;也可将衬套与嵌件注塑成一整体,在与导风轮同轴安装。将已装上衬套、嵌件的导风轮紧密装配在电扇的中心轴上,紧贴着导风轮,装上调整环,用轴挡件将调整环固定在电风扇的中心轴上,在调整环外及中心轴末端,装上风轮旋钮。轴挡件可选用卡圈,也可选用螺母。
本实用新型具有零件少,装置简单,结构合理,调整可靠,成本不高等优点。
附图1为本实用新型结构剖示图。
以250毫米座钟电风扇为例:电扇主体(11),垫圈(7,8),螺钉(6),销钉(19)。圆形的风轮旋钮(1)通过弹性调整环(2)来调控导风轮(10)的转速。轴挡件(9)选用圆形的弹性卡圈,并将调整环(2)固定在电扇的中心轴(4)上。嵌件(5)、衬套(3)与导风轮(10)依次紧密安装。
