一种搅拌机的安全开关

Abstract

本实用新型涉及小家电技术领域，具体涉及一种搅拌机的安全开关，包括开关支座、控制开关以及触发架，所述触发架包括连接体、触发凸块以及复位杆和触发杆，复位杆的外侧套设有复位弹簧；所述控制开关包括开关本体以及设置于开关本体左侧的弹片和控制按钮，弹片的一端与开关本体固定连接，弹片的另一端向左下方倾斜设置，控制按钮位于弹片的正右侧，触发杆位于弹片的正上方。本实用新型的搅拌机安全开关与电源控制开关配合使用，当搅拌杯安装后，触发凸块被压下，触发杆向下推动弹片，弹片抵压控制按钮以闭合开关，确保搅拌机仅在搅拌杯安装后才能运行，可以防止搅拌机异常启动，避免用户因误操作而受伤，提高搅拌机的使用安全性。
