[0026] In this embodiment, see the attached Figure 1-3 Before the water tank liquid level control device works, the height of the water outlet pipe 5 is adjusted according to the required outlet liquid level. The specific steps are: the water outlet pipe 5 is connected to the first water outlet 3 at the matching position by rotating the thread until the water outlet pipe 5 stops rotating. At this time, the large-area end of the water outlet pipe 5 abuts against the elastic plugging mechanism and pushes the elastic plugging mechanism out of the first water outlet 3, and the two second water outlets 4 of the water outlet pipe 5 can flow water;

[0027] When the water tank liquid level control device is working, sewage enters the water tank 1 through the water inlet pipe 2 until the liquid level in the water tank 1 reaches the position of the water outlet pipe 5, and the sewage is discharged through the water outlet pipe 5 to realize the liquid level control of the water tank 1.

[0028] Specifically, the elastic sealing mechanism includes a connecting spring 102 fixedly connected to the wall surface of the large-area section of the first water outlet 3 close to the small-area section, and a rubber sealing plug 101 arranged on the side of the large-area section of the first water outlet 3 away from the small-area section.
