[ technical field ] A method for producing a semiconductor device

The invention relates to the technical field of sanitary ware products, in particular to a toilet flushing system.

[ background of the invention ]

The toilet bowl is commonly called as a closestool, and the flushing mode of the toilet bowl is generally a direct flushing type and a siphon type. The inlet valve for toilet flushing has two outlets, one outlet is connected with the wall flushing side (RIM side) of the toilet, and the other outlet is connected with the siphon flushing side (JET side). Typically, the RIM side pipe outlet is located below the inner race of the toilet near the seat, and the JET side pipe outlet is located low at the water storage portion of the toilet.

The flushing mode of the flushing valve in the prior art comprises the following modes:

Because the driving power of the switch valve is lower, the switch valve can be driven by a dry battery, or a mechanical valve opening device can be added on the switch valve, and the switch valve is manually opened. However, the flushing effect of the on-off valve depends on the tap water pressure, and the flushing effect is poor when the pressure is low.

The second method comprises the following steps: as shown in fig. 2, a tank pump + a reversing valve is adopted. Although the problem that the low water pressure washing effect is poor can be solved to this mode, however, when the power failure state, all will drive the water pump and just can realize the power failure of closestool and wash, because the drive power of water pump is very big, so must adopt special big electric capacity or large capacity battery just can drive, with high costs, life is short to there is the potential safety hazard.

The third method comprises the following steps: as shown in fig. 3, a tank water pump + double switch valves is used. When normal state, adopt A and B water route to wash, when being in the power failure state, can adopt A and C water route to carry out the power failure washing mode of two ooff valves, though this power failure washing mode is simple, and is with low costs, long service life, but has installed two sets of rinse-system in other words, uses water tank + water pump mode when normal, and the power failure uses two ooff valves modes, and the system is more complicated, and control is also complicated, and is with high costs.
