The working principle of the invention is as follows:

the first cavity 1 is filled with an oil-water mixture, and water is deposited at the bottom of the first cavity 1 due to the fact that the density of the water is higher than that of fuel oil after a certain time;

the density of the floating ball 42 is set between the fuel oil and the water, and when the accumulated water is more, the buoyancy of the floating ball 42 is larger than the suction force of the water outlet magnet 111 and the drain plug magnet 411, the floating ball 42 drives the movable round rod 4 to rotate clockwise;

the movable round rod 4 rotates clockwise to cause the drain plug 41 to be separated from the water outlet 11, the third cavity 3 is opened by the connecting door connecting shaft 43, and the 150-degree L-shaped round rod at the tail end of the movable round rod 4 props against the drain door 22;

after the water outlet 11 is opened, the water pressure of the first cavity 1 discharges accumulated water at the bottom into the second cavity 2;

after the accumulated water in the first cavity 1 gradually descends, the floating ball 42 drives the movable round rod 4 to reset anticlockwise due to the upper fuel pressure, when the drain plug 41 approaches the water outlet 11, the water outlet magnet 111 and the drain plug magnet 411 attract each other to enable the water outlet to be completely closed, and the accumulated water in the second cavity 2 is volatilized by the heat of an engine entering from the air inlet 21 and the wind power generated by the running of an automobile;

in one embodiment, after the water outlet 11 is opened, because the oil quality of the oil tank is poor, a certain amount of water is still accumulated in the front space of the second cavity 2 and is not volatilized, the pressure in the first cavity 1 continues to press accumulated water to the second cavity 2 and send the accumulated water into the second cavity 2, the accumulated water can flow through the water stop plate 23 and enter the opened third cavity 3 to be temporarily stored, when the movable ring 4 is reset, the connecting door 31 of the third cavity 3 is closed, and the accumulated water is squeezed into the rear space of the second cavity 2 closing the drainage door 22 from the third cavity 3;

in another embodiment, the oil quality is bad seriously, the accumulated water in the rear space of the second cavity is not volatilized completely, and the floating ball 42 drives the movable round rod 4 to rotate clockwise to open the water outlet 11, the third cavity 3 and the drainage door 22; the water in the space behind the second cavity 2 flows away from the drainage door 22, the water pressure in the first cavity 1 pushes the accumulated water in the first cavity 1 to the front of the second cavity 2, and then flows into the third cavity 3 after spreading over the front of the second cavity 2.
