[0025] See also Figures 1 to 3The vehicle-mounted black water tank in the embodiment of the utility model includes a box body 100 and an overflow mechanism. A flushing pipe 200 is arranged around the top inner wall of the box body 100. The flushing pipe 200 is connected to an inlet pipe 210. One end of the inlet pipe 210 away from the flushing pipe 200 passes through the side wall of the box body 100 and is placed outside the box body 100 to connect to an external flushing water source. A plurality of flushing holes are provided on the flushing pipe 200 to discharge the flushing water in the flushing pipe 200 into the interior of the box body 100. A plurality of anti-sway plates 400 are arranged inside the box body 100. A plurality of through holes are provided on the anti-sway plates 400. The through holes penetrate the anti-sway plates 400. A cleaning port 130 is provided on the side wall of the box body 100. A cover body is detachably connected to the cleaning port 130. Preferably, the flushing pipe 200 is a closed square ring, the diameter of the flushing hole is 3 mm, and the flushing holes are divided into two groups, high and low, so as to more cleanly flush the inside of the box 100. Two anti-sway plates 400 are welded inside the box 100, and the through holes are made by stamping, so that the sewage in the box 100 can flow. It can be understood that the flushing pipe 200 surrounds the inside of the box 100 and can flush the inner wall of the box in all directions, and the flushing water flow is not blocked by the anti-sway plates 400.

[0026] The overflow mechanism includes an overflow portion 310 and an overflow pipe 300. The overflow portion 310 is disposed on the top surface of the box body 100. An overflow cavity is disposed in the overflow portion 310. The overflow cavity is connected to the inside of the box body 100. One end of the overflow pipe 300 is connected to the overflow cavity and is placed in the overflow cavity. The end face of the end of the overflow pipe 300 placed in the overflow cavity forms an acute angle with the top surface of the box body 100. One side of the end face is at a height of 1.5° from the top surface of the box body 100. The overflow portion 310 is flush with the bottom of the box body 100, the projection area of ​​the overflow portion 310 on the horizontal plane is larger than 4 times the projection area of ​​the end face on the horizontal plane, the end of the overflow pipe 300 facing away from the overflow portion 310 passes through the bottom of the box body 100 and is connected to the overflow port, a sewage outlet 140 is arranged at the bottom of the box body 100, a water level sensor 160 is arranged on the top of the box body 100, and a plurality of float switches 170 are arranged on the inner side wall of the box body 100, and the float switch 170 is used for liquid level alarm. Preferably, the sewage outlet 140 is connected to a butterfly valve, the butterfly valve is connected to an external fire-fighting joint, the overflow portion 310 is a rectangular parallelepiped, the angle between the end face and the top surface of the box body 100 is 45°, the water level sensor 160 is used to monitor the liquid level of the sewage, and two float switches 170 are arranged on the inner wall of the box body 100, one is located at the top of the box body 100, and the other is located in the middle position of the box body 100, so as to timely issue a liquid level alarm to remind vehicle users to pay attention to the liquid level of the black water tank in time. It can be understood that when the sewage level in the box 100 reaches the top surface of the box 100, and sewage and gas enter, the sewage will enter the overflow pipe 300 from the end surface flush with the box 100, and will be discharged to the bottom of the box 100 as gravity drops, and then discharged through the overflow port. The gas is discharged through the overflow port in the same way, and the gas brought by the sewage can be temporarily stored in the overflow portion 310 to buffer and prevent air pressure from hindering water inflow and preventing air pressure from hindering water inflow. The sewage overflows to the top of the box body 100, which improves the utilization rate of the internal space of the box body 100. Since the position for discharging the overflow sewage is at the bottom of the box body 100, it effectively avoids the problem that the overflow sewage is discharged from the top of the traditional black water tank, which is easy to cause sewage leakage due to aging and loosening, thereby polluting the outer surface of the black water tank and the interior of the vehicle body. In addition, the pipeline for discharging the overflow sewage can be designed at the bottom of the black water tank, which is easier to layout and does not occupy the internal space of the vehicle body above the black water tank. In addition, the pipeline is located at the bottom of the black water tank, which is easier to maintain.

[0027] The top of the box 100 is provided with a sewage inlet 150, and a plurality of slopes 110 are provided inside the box 100. The slopes 110 are located at the bottom of the box 100 to guide the sewage to flow to the sewage outlet 140, and the height of the slopes 110 is less than or equal to 20 mm. Preferably, two slopes 110 are provided, and the sewage outlet 140 is located at one side of the bottom of the box 100, so one of the two slopes 110 is a long slope and the other is a short slope. Specifically, the short slope connects the inner wall of one side of the box 100 closer to the sewage outlet 140, and the height of the short slope is 10 mm, and the height of the long slope is 20 mm, so as to guide the sewage to flow through a longer path faster and reach the sewage outlet 140. It can be understood that the inner side of the bottom of a traditional black water tank is a plane, and water is easily accumulated in a position far away from the sewage outlet 140, affecting the discharge. The use of a sloped design helps to improve the discharge efficiency of sewage.
