[0022] The worm gear 2 is meshed with the worm shaft 2, and the rotation of the shaft will drive the resistance plate to rotate together. Under normal conditions, the resistance plate will press the pressure column, so that the sealing plug will be blocked inside the sewage outlet to ensure the normal flow of water. As the resistance plate rotates, when the arc-shaped notch is opposite to the pressure column, the sealing plug will open under the pull of spring 3, so that the sewage outlet will open and sewage will be discharged, thereby achieving the effect of regular automatic sewage discharge.
