The invention provides a fuel tank oil suction port structure which comprises a fuel tank body, an oil outlet pipe and a control device, a fuel cavity is formed in the fuel tank body, an oil inlet and at least two oil suction ports are formed in the fuel tank body, the oil inlet and the oil suction ports are communicated with the fuel cavity, and the two oil suction ports are located on the two opposite sides of the bottom of the fuel tank body; the number of the oil outlet pipes is at least two, each oil suction port is provided with one oil outlet pipe, one end of each oil outlet pipe is connected to the corresponding oil suction port and communicates with the fuel oil cavity, and the other end of each oil outlet pipe communicates with the oil conveying pipe. The control device is arranged on the oil outlet pipe or between the oil outlet pipe and the oil conveying pipe and used for controlling connection and disconnection between the oil outlet pipe and the oil conveying pipe according to oil pressure in the oil outlet pipe. Meanwhile, the invention further provides the fuel tank. Compared with the prior art, the fuel suction port structure of the fuel tank and the fuel tank can reduce the lowest fuel level in the fuel tank and reduce the frequency of the air suction phenomenon of an engine.

    本发明提供了一种燃油箱的吸油口结构,其包括燃油箱本体、出油管及控制装置,燃油箱本体内部具有燃油腔且开设有分别与燃油腔连通的进油口与吸油口,吸油口至少设置有两个,两吸油口位于燃油箱本体底部的相对两侧;出油管至少设置有两个,且每个吸油口均设置有一个出油管,出油管的一端连接于对应的吸油口并与燃油腔连通,出油管的另一端与输油管连通;控制装置设置于出油管或出油管与输油管之间,用以根据出油管内的油压来控制出油管与输油管之间的通断。同时本发明还提供了一种燃油箱。与现有技术相比,本发明的燃油箱的吸油口结构及燃油箱能降低燃油箱中的最低油位,降低发动机的吸空现象的频率。
