图3为本发明的填有吸油填料的结构示意图。
具体实施方式
以下结合附图对本发明的原理和特征进行描述，所举实例只用于解释本发明，并非用于限定本发明的范围。
如图1、图2、图3所示，一种分离式碳灌油箱盖，其包括碳灌、油箱盖3，碳灌包括油箱外盖1、碳盖2；碳盖2的中部设有上端开口的填充腔4，油箱外盖1设置在碳盖2的上方，且油箱外盖1包裹住填充腔4的上端口，油箱外盖1与碳盖2之间连接处采用非密封连接，非密封连接可以方便过滤后的油气排放到外界；油箱外盖1的内壁与碳盖2的外侧可以采用卡合连接。油箱盖3设置在碳盖2的下方，油箱盖3上设有用于与油箱口相连接的卡槽5，优选这卡槽5内设有O型密封圈。油箱盖3与碳盖2和油箱外盖1之间通过可拆卸方式连接、或油箱盖3与碳盖2之间通过可拆卸方式连接、或油箱盖3与油箱外盖1之间通过可拆卸方式连接；油箱盖3的中部设有贯穿油箱盖3上、下端面的通孔6，碳盖2上设有第一通道7，第一通道7将通孔6与填充腔4相连通，第一通道7用于将油箱中的挥发的油气导入到填充腔4中，油气经过填充腔4内吸油填料8过滤后排放到外界，以达到控制燃油排放、减少污染的目的。填充腔4内设有吸油填料8。
本发明还包括通气管9，通气管9设置在碳盖2内；通气管9套在第一通道7的出口上，通气管9的下端设有第一呼吸板10；第一呼吸板10、碳盖2的底部、碳盖2的内壁形成容积腔11；通气管9的内壁与填充腔4的内壁之间设有第二通道12，第二通道12将第一通道7的出口与容积腔11相连通。第二通道12的作用：第一、改变第一通道7内油气的流通方向，使得流速减小；第二、增加了油气在碳盖2中的过滤时间，有利于油气中有害物质充分吸收；第三、将油气导入到容积腔11中，有利于容积腔11存储的少量油。吸油填料8设置在第一呼吸板10的上方，且吸油填料8至于填充腔4中。
碳盖2的底板设有贯穿底板的支柱13；支柱13的上端穿过容积腔11置于填充腔4中，且容积腔11环绕着支柱13的下端；通气管9的下端置于容积腔11中；第一通道7贯通支柱13；通气管9套在支柱13上，通气管9的内壁与支柱13的外壁形成第二通道12。本实施例不需要通气管9的内壁与支柱13的外壁密封连接，因为通气管9完全套住支柱13，通气管9下端的出气口完全置于容积腔11中，第一通道7中的油气都会流进容积腔11中。
支柱13的下端置于油箱盖3中，支柱13的下端与油箱盖3之间通过可拆卸方式相连接。支柱13的下端与油箱盖3的连接处设有密封圈。
优选：第一呼吸板10的下端设有支撑件14，支撑件14设置在第二通道12下端口的上方，这样才能使得通气管9下端的出气口在容积腔11中。支撑件14的上端面上设有多个通气孔，这样有利于容积腔11中的油气通过第一呼吸板10进入填充腔4内；支撑件14与通气管9的外壁固定连接。支撑件14的结构可以为圆环，进一步还可以圆环的周边设置向容积腔11内伸入的圆筒；圆筒的高度和容积腔11的深度相等，这样起到支撑的作用；支撑件14的上端面(也就是圆环的上端面)与填充腔4的底面相齐平，这样有利于放置第一呼吸板10(优选：第一呼吸板10在盖住容积腔11的上端口的同时也盖住填充腔4的底面)。更优：支撑件14与通气管9一体成型。
优选：本实施例还包括用于盖住吸油填料8的第二呼吸板15，第二呼吸板15设置在填充腔4的上端口上。第二呼吸板15用于防止吸油填料8漏出。更优选：填充腔4上端口的圆周设有方便嵌入第二呼吸板15的环台，油箱外盖1的下端面设有下压第二呼吸板15的凸起，通气管9上设有支撑第二呼吸板15的台阶；通气管9的上端可以穿过第二呼吸板15至油箱外盖1的下方，也可以不用穿过第二呼吸板15，本实例优选通气管9穿过第二呼吸板15至油箱外盖1的下方，且通气管9的上端面与油箱外盖1的下端面相接触，通气管9不但可以支撑第二呼吸板15，还可以支撑油箱外盖1。第二呼吸板15的上方可以设有隔片16，隔片16设置于油箱外盖1与第二呼吸板15之间，方便平压第二呼吸板15，起到更好防止吸油填料8漏出。
优选：支柱13内设有呼吸海绵17，且呼吸海绵17在第二通道12上。这样更有利于减缓油气流速。还可以在第二通道12上设置隔板，呼吸海绵17可以在设置在隔板的上端或下端，本实例没有在第二通道12上设置隔板。
优选：吸油填料8为活性炭。
使用过程中先将油箱盖3正确装在油箱上，然后碳灌(碳灌的碳盖2)与油箱盖3快捷连接在一起。碳灌是一个标准件，油箱的少量油气经过油箱盖3后首先经过呼吸海绵17缓冲，然后通气管9让油气折返进入碳盖2，最后进入活性炭里，经过活性炭过滤后的气体再经过第二呼吸板15排放到大气中。碳罐和油箱盖3相互独立，通用性强，可以适用不同的油箱盖3。结构设计简易化，制造加工简单化，成本降低。由于通气管9具有使油气折返功能，进入容积腔11的少量油将会在油箱负压作用下，沿着油/气流动方向回流到油箱里，避免油对碳粉的长期浸泡，让碳粉的吸附性发挥更佳。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
