Abstract

一种换气扇,扇身为圆形,后盖板为一块整板,内侧设一凸块,其位置与设在电机后盖上的微动开关的位置相对应,扇身和后盖板通过扭簧连接,后盖板边缘系一拉线,其另一头穿过扇身上设置的带有可夹住拉线结头的小槽的孔而向下悬垂。本实用新型可直接安装在窗玻璃上,使用方便且显得美观,对采光影响较小。

Description

换气扇
本实用新型属于家用电器。
现有换气扇的扇身一般为方形,其后盖板呈百叶窗形状,在安装到窗上时,需将窗玻璃卸掉,带来一定的麻烦,且影响美观和采光。
本实用新型的目的是提供一种结构新颖、安装方便的换气扇。
本实用新型所提供的换气扇包括扇叶(2)、扇身(4)、面板(1)、电机(8)、后盖板(5),其扇身(4)为圆形,后盖板(5)是一块整板,扇身(4)和后盖板(5)通过扭簧(9)连接,使后盖板(5)在无外力控制时可翘起,在电机(8)后盖上设置一微动开关(6),在后盖板(5)内侧与微动开关(6)相对应的位置设置一凸块(7),当后盖板(5)呈关闭状态时,其内侧的凸块(7)正好压住微动开关(6),使其断开电源,在后盖板(5)边缘位置系一拉线(3),其另一头穿过扇身(4)上设置的带有可夹住拉线结头的小槽的孔(10)而向下悬垂。
本实用新型使用时,当后盖板(5)呈关闭状态,拉线(3)上的结头正好被扇身(4)上所开孔(10)内的小槽卡住,后盖板(5)不会自动翘起,这时后盖板(5)上的凸块(7)压住微动开关(6),电源断开;当将拉线(3)的结头拉离小槽并松手后,后盖板(5)由于其与扇身(4)连接的扭簧(9)的弹力作用,使后盖板(5)翘起,凸块(7)脱开微动开关(6),接通电源,换气扇开始运转。
本实用新型的扇身呈圆形,安装时只需在窗玻璃上划一个比扇身(4)略大的圆孔,再在圆孔四周嵌上一圈塑料条,即可将本实用新型直接安装在玻璃圆孔内,十分简便且显得美观,对采光影响也较小。
图1为本实用新型的正面示意图,图2为侧面示意图,图3为卸下后盖板(5)以后的后面示意图,图4为后盖板(5)的侧面示意图。
图中1为面板,2为扇叶,3为拉线,4为扇身,5为后盖板,6为微动开关,7为后盖板内侧的凸块,8为电机,9为扭簧,10为扇身(4)上的孔。
