How was the toilet invented?

Who invented the toilet, even many experts can't tell. One theory is that in 1596, John Harington, a British aristocrat, invented the first practical toilet-a wooden toilet seat with a water tank and a flush valve. Before that, many people always ran to the nearest big trees and rivers to solve the problem on the spot. Although Harrington invented the toilet, it was not widely used because of the imperfect sewage system. 186 1 year, Thomas kleppa, a British plumber, invented an advanced water-saving flushing system, and waste discharge began to enter a modern period.

The British inventor Joseph Bram improved the design of the toilet in the late18th century. He used some components, such as a three-ball valve to control the water flow in the water tank and a U-bend to ensure that the smell of the sewage pipe would not be smelled by users. He obtained a patent for this toilet on 1778. An important feature of the toilet is the S-shaped pipe, or the trap of the sewer, which always keeps some water. This water is equivalent to a gasket, covering up the odor.

The invention of the toilet can really be called a classic in the civilization of human life. In recent decades, innovations have been made, including "mobile toilets", "non-contact toilets" and "computer-monitored water-saving toilets". With the application of high technology, modern toilets can even detect users' 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.
