The invention relates to the technical field of controllers, in particular to a wireless radio frequency controller for an electric hoist. The problem that in the prior art, a wireless radio frequency controller cannot conveniently and rapidly remove dust at a switch contact inside the controller is mainly solved. According to the technical scheme, the controller comprises a controller body, two rolling wheels rotationally connected to the top face of the controller body, a mounting groove formed in the controller body and close to the lower portions of the rolling wheels, pressure switches symmetrically connected to the side faces of the rolling wheels, and switch contacts connected to the positions, close to the pressure switches, of the inner bottom face of the mounting groove. In the using process, a pressing plate moves upwards in a second connecting groove, gas in a second connecting pipe enters the second connecting groove, namely, one connecting box and a first connecting pipe generate an air suction effect, gas with dust at a switch contact is sucked into the second connecting groove, and the dust is sucked into the second connecting groove. And the dust removal effect is achieved through blowing and sucking actions, so that the working effect of the switch contact is ensured.

    本发明涉及控制器技术领域,具体涉及电动葫芦用无线射频控制器。其主要针对于现有技术中无线射频控制器不能方便快捷的对控制器内部开关触点处进行除尘的问题,提出如下技术方案:包括控制器本体、两个转动连接于控制器本体顶面的滚轮、开设于控制器本体内部靠近滚轮下部的安装槽、对称连接于滚轮侧面的压力开关以及连接于安装槽内底面靠近压力开关位置的开关触点。本发明在使用的过程中,压板在第二连接槽的内部向上移动,第二连接管内部的气体进入至第二连接槽的内部,即其中一个连接盒、第一连接管产生吸气效果,将开关触点处带有灰尘的气体吸入至第二连接槽的内部,进而通过一吹一吸的动作达到除尘的效果,进而保证开关触点的工作效果。
