The invention discloses a self-water removal device for automobile rearview mirror which comprises a rearview mirror body and a mirror surface embedded in the rearview mirror body; a heating water removal device is arranged on the mirror surface; a cylindrical cavity and a cavity are formed in the rearview mirror body; the cylindrical cavity is located above the cavity; a sliding rod is slidably connected to the center of the top of the cylindrical cavity in a penetrating mode, the upper end of the sliding rod penetrates through the top of the rearview mirror body and is welded with a wing plate, piezoelectric ceramic is fixedly connected to the bottom of the cylindrical cavity, and an energy storage device is arranged in the cylindrical cavity. The device has the advantages that after thepiezoelectric ceramic is impacted, an electromagnet is electrified to generate magnetism, air above a piston plate is compressed, and then high-speed airflow attached to the mirror surface is blown out from the air outlet hole in the upper portion of the mirror surface through an air guide pipe, so that water on the mirror surface is rapidly removed; meanwhile, circuits of a first conductive strip and a second conductive strip are conducted through water drops, so that the piezoelectric ceramic performs point heating on the water drops, and the water removal efficiency is improved.
本发明公开了一种汽车后视镜自除水装置,包括后视镜本体和嵌设在后视镜本体上的镜面,所述镜面上设有加热除水装置,所述后视镜本体内开设有一个圆柱腔和空腔,所述圆柱腔位于空腔的上方位置,所述圆柱腔的顶部中心位置贯穿滑动连接有一根滑杆,所述滑杆的上端贯穿后视镜本体的顶部且焊接有一块翼板,所述圆柱腔的底部固定连接有一块压电陶瓷,所述圆柱腔内设有蓄能装置。优点在于:本发明中压电陶瓷受撞击后使电磁铁通电产生磁性,将活塞板上方的空气压缩后经导气管从镜面上方的出气孔吹出贴合镜面的高速气流,快速对镜面除水,同时通过水珠导通第一导电条和第二导电条的电路使得压电陶瓷对水滴进行点加热,提高除水效率。
