description The utility model relates to the technical field of negative-pressure water discharging devices, in particular to a negative-pressure water discharging device which comprises a water discharging device body, a water inlet pipe fixedly connected to one side of the water discharging device body, a water discharging pipe fixedly connected to one side of the water discharging device body, and an atmospheric valve fixedly connected to one side of the water discharging device body. The top of the water discharging device body is fixedly connected with a top cover, and one side of the water inlet pipe is fixedly connected with a filtering mechanism. The negative-pressure water drainer has the advantages that sucked accumulated water is filtered through the filter screen, so that impurities such as dregs and sand in the accumulated water are filtered and blocked, the dregs are prevented from entering the negative-pressure water drainer to block a pipeline, and the accumulated water is more difficult to drain; therefo
