Automatic water drainage device and water drainage method for floating block flow guide diesel oil filter

The invention relates to the technical field of vehicle fuel oil systems, in particular to an automatic water drainage device and method for a floating block flow guide diesel oil filter. The device comprises a water accumulating cup, a flow guide pipe, a first electric conductor, a lead pipe, a water inlet pipe, a trigger device and a timing electromagnetic valve. The water accumulating cup has a closed lower part and an open upper part; the flow guide pipe is of an annular tubular body structure, and a flow guide hole is formed in the lower portion of the flow guide pipe. Through combination of a mechanical structure and an electrical connection mode, the automatic water drainage function of the water accumulation cup is achieved. 本发明涉及车辆燃油系统技术领域，具体涉及一种浮块导流柴油滤清器自动放水装置及放水方法。其包括：积水杯、导流管、导电体一、引线管、进水管、触发装置、计时电磁阀；所述积水杯下部封闭上部开放；所述导流管为环形管状体结构，其下部设有导流孔。本发明通过机械结构结合电气连接方式的设置，实现了积水杯自动放水的功能。
