A low-water-level intelligent non-negative-pressure water supply device with a detection function comprises a pump set and a pump set base which are communicated through a pipeline, a water inlet pipe is connected between the pump set and the pump set base, and a low-water-level protection device is arranged at the bottom of the water inlet pipe. The low-water-level protection device comprises a circulation pipeline communicated with the water inlet pipe, and sealing flanges are arranged at the two ends of the circulation pipeline. The circulation pipeline is connected with all the water inlet pipes, and the circulation pipeline and all the water inlet pipes form an annular loop; compared with the prior art, the low-water-level protection device is arranged, and the pump set base is connected to the water tank, so that water flow at the water outlet end of the water tank is detected, it is ensured that air in the water flow entering the water inlet pipe is little, and redundant air can be exhausted through th
