The invention provides a self-cleaning rain and snow sensing device, and relates to the technical field of weather detectors. The device comprising a rain and snow sensor and an air nozzle fixed on aninclined surface. A nozzle opening of the air nozzle faces a sensing surface of the rain and snow sensor, the air nozzle is connected to an air compression pump through a pipeline, a solenoid valve is arranged on the pipeline between the air nozzle and the air compression pump, and the rain and snow sensor and the solenoid valve are electrically connected to a controller separately. According tothe self-cleaning rain and snow sensing device, the problem in the prior art that surface volume of the rain and snow sensor is attached to rain and snow so that the judgment and timeliness are poor is solved. 本发明提供了种自清洁雨雪感应装置，涉及天气检测仪技术领域，其包括固定于倾斜面上的雨雪传感器和空气喷嘴，空气喷嘴的喷嘴口朝向雨雪传感器的感应面，空气喷嘴通过管道连接于空气压缩泵上，空气喷嘴和空气压缩泵之间的管道上设置有电磁阀，雨雪传感器和电磁阀分别电连接于控制器上。解决了现有技术中的雨雪感应装置由于雨雪传感器表面容积附着雨雪导致误判和时效性差的问题。
