Description

Water-saving toilet

Technical Field

The invention relates to the field of bathrooms, in particular to a water-saving toilet bowl.

Background

As shown in fig. 1, in the conventional toilet bowl, after the drain valve is opened, water in the water tank firstly flows into the common auxiliary water channel 1000, and then flows into the brush ring water pipe 1001 and the injection water pipe 1002 respectively, and since the common auxiliary water channel 1000 is common, the water amount cannot be reasonably allocated to the brush ring water pipe 1001 and the injection water pipe 1002 of the toilet bowl. The 'water volume ratio' respectively divided by the brush ring water pipeline 1001 and the jet water pipeline 1002 changes along with the change of the working water level of the toilet water tank, so that the 'brush ring water' or 'siphon water' consumption of the toilet exceeds the flushing demand of the toilet and water is wasted.

Meanwhile, when the existing toilet bowl is in a normal water stop state, outside air is communicated with the water discharge valve base water outlet through the overflow pipe, and when an overflow phenomenon occurs, water flows to the water discharge valve base water outlet from the overflow pipe and enters a toilet bowl pipeline. When the valve base is normally used, the water outlet of the valve base is communicated with the outside air through the overflow pipe channel, negative pressure can be generated in the water outlet channel when the drain valve drains water, and air can be mixed into the water outlet of the valve base together under the action of external atmospheric pressure, so that the water outlet channel is not in a full pipe water state, the water draining speed is reduced, and the flushing effect is weakened.
