Abstract

本实用新型公开了一种散风式吊扇叶片。将一 般使用的吊扇叶片改变成为一定的圆弧形状,当吊扇 运转时,扇出的风向四周散射开来,受风面积范围扩 大。

Description

本实用新型涉及一种电风扇的叶片,尤其是一种吊扇的叶片。
在现有的吊扇中,其叶片的形状一般为水平状的长方体,当吊扇在运转中叶片扇出的风,由于受风面积比较窄,一般家庭居室使用比较适宜,而在公共场所或空间比较大的地方受风效果就不理想。
本实用新型的目的,提供一种受风面积较宽的散风式吊扇叶片。
本实用新型的目的是这样实现的:将吊扇的叶片从叶根1到叶顶2弯曲成 (π)/4 弧度的圆弧形,即叶片中心的圆弧所对应的圆心角为45°。当吊扇运转时,扇出的风向四周散射开来,大大增加了受风面积。
本实用新型的优点是:
1、由于叶片弯曲,整个转动系统的转动惯量和阻力臂减小,起动速度加快。
2、受风面积扩大,适用范围广。
下面结合附图对本实用新型作进一步说明:
图1为吊扇叶片的结构原理图和主视图;
在图1所示的吊扇叶片的结构原理图和主视图中,叶片从叶根1到叶顶2弯曲成 (π)/4 圆弧形,即叶片中心线所对应的圆心角为45°,弯曲的叶片与吊扇的机身连接,当吊扇运转时扇出的风向四周散射开来,扩大了受风面积。
图2和图3分别为图1的俯视图和左视图。

Claims (2)
