Even many experts cannot tell who invented the flush toilet. One theory is that in 1596, the British aristocrat John Harrington invented the first practical toilet - a wooden seat with a water tank and a flush valve. Before that, many people always went to the nearest big tree. And solve it on the spot in Xiaoheli. Although Harrington invented the toilet, it was not widely used due to the imperfect sewage system. In 1861, British plumber Thomas Klepper invented an advanced water-saving flushing system, and waste discharge began to enter the modern era.
British inventor Joseph Brame improved the design of the flush toilet in the late 18th century. He used some components, such as a three-ball valve to control the flow of water in the water tank, and a U-shaped bend to ensure that the odor of the sewage pipe is not smelled by users. He patented this flush toilet in 1778. An important feature of a flush toilet is the S-tube, or sewer trap, which always holds some water. This water acts as a seal, covering up the odor.
The invention of the toilet can really be regarded as a classic in human civilization. In recent decades, it has continued to introduce new ones, including "mobile toilets", "non-contact toilets", "computer toilets" and "mobile toilets". Monitor water-saving toilets” and more. With the application of high-tech, modern toilets can even detect the user's blood pressure, fat, heart rate and analyze urine. These detected data can also be directly transmitted to the medical center through the network connected to the toilet.
