The "water ratio" of the brush ring water pipe 1001 and the jet water pipe 1002 changes with the working water level of the toilet tank, which easily causes the consumption of the brush ring water or the siphon water of the toilet to exceed the flushing demand of the toilet, and waste water.
Meanwhile, when the existing toilet is in a normal water stopping state, external air is communicated with the drain valve base drain outlet through the overflow pipe, and when overflow phenomenon occurs, water flows from the overflow pipe to the valve base drain outlet and enters a toilet pipeline. When the valve is normally used, the water outlet of the valve base is communicated with the outside air through the overflow pipe channel, negative pressure is generated in the water outlet channel when the drain valve drains water, and under the action of external atmospheric pressure, air is mixed into the water outlet of the valve base together, so that the water outlet channel is not in a full-pipe water state, the water outlet speed is reduced, and the flushing effect is weakened.
