Description

Drain valve device and toilet bowl

Technical Field

The utility model relates to the field of bathrooms, in particular to a drain valve device and a toilet bowl.

Background

In the existing common double-gear spraying siphon closestool, a water guide pipeline connects a spraying pipeline and a washing ring pipeline, water in a water tank flows into the water guide pipeline from a water outlet of a double-gear water discharging valve, one path of water is sprayed out from a spraying opening at the bottom of a pelvic cavity through the spraying pipeline, and the other path of water is sprayed out from a washing ring washing hole at the upper part of the pelvic cavity through the washing ring pipeline. Once the structure is formed, the distribution ratio of the water in the water tank between the jet opening and the washing ring flushing hole is fixed, and the distribution ratio of the water between the jet opening and the washing ring is basically the same regardless of large-grade washing or small-grade washing.

With this arrangement, for large flush, the stool being flushed is easily clogged, and the toilet is usually designed so that most of the water is ejected from the bottom jet orifice to push the waste and prevent clogging, i.e., most of the water is dispensed to the jet pipe. For small-scale flushing, the urine flushed by the toilet bowl is not blocked, but the urine easily splashes dirt on the pelvic cavity, and more water should be properly distributed to the washing ring for flushing the pelvic cavity splash in turn, but the problem cannot be solved because the distribution ratio of the water between the spray and the washing ring can only be the same when the toilet bowl is flushed in large scale and small scale. The problems are more obvious on the water-saving closestool, because the water consumption is very small, a large scale has to use more proportion of water for the injection opening to inject and prevent blockage, the water consumption of a small scale is very small originally, and more proportion of water has to be used for injection as the large scale, and as a result, the water of a washing ring is often as little as wetting the basin cavity, some water even the basin cavity can not be completely washed, and the splashing is not washed clean.

At present, although some common spray siphon toilets are provided with two water outlets so as to realize independent water supply of spray and washing rings, theoretically, the common spray siphon toilets have the capability of adjusting the water distribution proportion, but only can realize single-level flushing due to the limitation of a drainage device, so that the problems cannot be solved.
