As shown in fig. 1. The embodiment of the utility model provides an intelligent liquid level control device which mainly comprises a water storage tank 1, a probe seat 3 and a controller 2, wherein the shape and the structure of the water storage tank are not limited, for example, the water storage tank can be designed into a barrel shape, a cuboid shape and the like, the material of the water storage tank is not limited generally, and the tightness is ensured.
The outside of the water storage tank 1 is respectively communicated with a water inlet pipe 4, a water outlet pipe 5 and an overflow pipe 6, and the joint of the water outlet pipe 5 is generally arranged at the bottom of the water storage tank 1 so as to facilitate water drainage; the water inlet pipe 4 is provided with a control valve 41 and a gate valve 42, the water inlet pipe is used for externally connecting a water source, and the gate valve is a mechanical valve so as to open a pipeline of the water inlet pipe.
