One side of the shell 1 is fixedly connected to the upper flange 2 and the middle flange 3, and a connecting block 5 is provided on the lower surface of the shell 1. The connecting block 5 is fixedly connected to the lower flange 4 through a bent pipe. The pipes on one side of the upper flange 2 and the middle flange 3 are connected to the shell 1 and are internally interconnected. The upper flange 2 and the middle flange 3 are connected to the water tank through the rotational cooperation of bolts and screw holes.

More specifically, a glass plate is installed on one side of the liquid level tank 9, and the glass plate is convenient for checking the liquid level inside. A partition is installed on the other side of the liquid level tank 9, and the partition is used to separate the liquid level tank 9 from the placement tank 14 to prevent the float 10 inside the liquid level tank 9 from running into the placement tank 14. The liquid level tank 9 is located between the partition and the glass plate. A round tube is installed at the bottom of the shell 1, one end of the round tube is connected to the liquid level tank 9, and the other end is installed on the connecting block 5. A round hole is opened in the middle of the connecting block 5, and the round tube at the bottom of the shell 1 is adapted to the round hole in the middle of the connecting block 5;

The fluorescent stick 13 will automatically illuminate the liquid level tank 9 at night or in dimly lit scenes, making it easy to check the floating position of the float 10 inside the liquid level tank 9. By observing which line of the liquid level scale line 11 the floating position of the float 10 is parallel to, the actual water level inside the water tank can be obtained.

Embodiment 2

Specifically, a glass plate is installed on one side of the placement groove 14 and a partition is installed on the other side. The glass plate on one side of the placement groove 14 is used to prevent flying insects and debris. An inner groove 15 is opened on one side of the placement groove 14. A fluorescent stick 16 is installed on the inner side of the inner groove 15. The fluorescent stick 16 is used for lighting. At night or in a dark scene, the fluorescent stick 16 lights up to facilitate viewing the rising temperature of the thermometer 17.

A thermometer 17 is installed inside the placement tank 14, and a temperature sensing probe 18 is installed at the lower end of the thermometer 17. Mercury is arranged inside the temperature sensing probe 18. A capillary is arranged inside the thermometer 17.
