The invention discloses an automobile fuel evaporation pollution control device in the technical field of automobile fuel pollution. The device comprises a connecting pipe with an external thread, a first screw plug, a first air pressure sensor, a reaction barrel and a micro electromagnetic valve. The first screw plug is screwed at the top end of the connecting pipe. The device is connected with an existing automobile fuel tank threaded opening through the external thread on the connecting pipe, and an automobile power supply supplies power to the whole device. The first air pressure sensor and a second air pressure sensor detect air pressure inside and outside a fuel tank. Data comparison is carried out through a processor and a comparison unit. If the internal air pressure and the external air pressure are different, a micro motor and the micro electromagnetic valve are started, and reversely-installed fan blades suck air to enable the internal air pressure and the external air pressure to be the same. Evaporated gasoline is filtered through an activated carbon layer, and pollution is reduced. The device is not provided with a run-through air pressure balance channel, direct diffusion of the evaporated gasoline into the atmosphere is reduced, and the operation is convenient.

    本发明公开了汽车燃油污染技术领域的一种汽车燃油蒸发污染控制装置,包括设置有外螺纹的连接管、第一螺旋塞、第一气压传感器、反应桶和微型电磁阀,第一螺旋塞螺接在连接管的顶端,通过连接管上外螺纹与现有的汽车油箱螺纹口连接,利用汽车电源对装置整体供电,第一气压传感器和第二气压传感器分别检测油箱内外气压,通过处理器和对比单元进行数据比对,两者不同,启动微型电机和微型电磁阀,反装的扇叶进行吸风,使内外气压相同,通过蒸发汽油通过活性炭层过滤,减少污染,该装置未设计贯穿气压平衡通道,减少蒸发汽油直接扩散到大气中,操作方便。
