After the rain stops, as the rainwater stored in the device decreases, the floating ball automatically resets under the action of buoyancy, and the garbage generated by filtering in the bucket is taken out. Under the action of the suction pump, it flows into the filter along the diversion pipe, and some gas in the water is filtered out through the aeration and oxygenation device, and the water flows into the water inlet pipe from the diversion pipe on the aeration and oxygenation box. , the water is filled upwards, when it is filled to the upper end of the water inlet pipe, the water overflows and is sprayed onto the water sieve device. During the spraying process, it can absorb the oxygen in the air, and then through the self-flushing device, the water level in the siphon rising pipe continues to rise. When the water level reaches the mouth of the siphon auxiliary pipe, the water falls from the pipe, and the air in the siphon descending pipe is continuously taken away through the suction pipe, so that a vacuum is formed in the siphon pipe, and the siphon effect occurs, and the water in the water tank flows from bottom to top. Through the filter layer, the filter material is backwashed and finally flows into the water storage tank. The outlet pipe of the water storage tank is directly connected with the water inlet pipe of the pipeline and transported to the home. The water inlet pipe and the household water pipe are not the same pipe, and the water can be flushed For the toilet.
