Technical Field

The invention relates to a closestool for preventing flushing water from splashing.

Background

The existing toilet bowl (closestool) in the market is a pressure flushing closestool or a gravity flushing closestool, or a flushing type closestool or a siphon type closestool, basically, the toilet bowl is quickly and powerfully impacted by water to discharge excrement out of a closestool pipeline, the common closestool is basically divided into two water paths, one path of the water path is used for flushing the bowl surface of the closestool so as to brush paper towels or water seals from urine to the body, and the other path of the water path is used for quickly impacting the human excrement which possibly contains the paper towels or urine or excrement. Because the impact force of water is generally larger, when the excrement is impacted, some microscopic dirt or bacteria or viruses on the excrement are likely to be splashed out of the body, so that objects or human bodies around the closestool are polluted, and further great hidden dangers are generated to human health.

A comparison experiment has been carried out by the American FDA (food and drug administration), two identical toilet scenes are built in a laboratory, the fluorescent agent for the first time is used as a judgment evidence, one toilet closes the toilet cover to flush water, the other toilet does not close the toilet cover to flush water, the result shows that water splash can splash to a distance of 1.6 feet when the toilet without the toilet cover flushes water, and a plurality of articles are stained with the fluorescent agent within the radius range. The results were consistent with the second test with E.coli. Such experiments confirm our concerns, but in reality we cannot educate everyone about closing the lid when flushing the toilet, and many people will not do so for the sake of hygiene and convenience of operation, so it becomes very interesting to solve this problem in the design of the toilet.
