In the era of Queen Elizabeth I (A.D. 1558- 1603), there was a Sir John Harington in England who loved literature at ordinary times and was sentenced to exile for spreading a so-called indecent story.
During the period of 1584- 159 1, he built a house in Kelston, England, where he designed the world's first toilet, which was connected to a water storage tank and installed in this house.
1775, a London watchmaker named Alexander Cumming improved Harrington's design, invented the valve device, developed the toilet, and obtained the patent for the first time.
Extended information toilet is a culture medium for bacteria.
Toilet is a necessary thing to remove human excrement, and it is also a place where bacteria can easily stay. Experiments show that the number of bacteria in the inner wall of the toilet is obviously higher than that in the upper edge of the toilet and the reservoir, because the inner wall of the toilet is suitable for bacterial growth.
These bacteria include Escherichia coli, aerogenes, Proteus, Pseudomonas aeruginosa, Candida and so on. It was found that 32% toilets were contaminated by Shigella sonnei, and the survival time of Shigella sonnei on the toilet seat was 17 days.
The sanitary condition of the bathroom is closely related to the air pollution in the bathroom. When the siphon toilet used in modern families is flushed, it will produce strong airflow, which will spread a large number of bacteria in the toilet into the air and pollute the air.
Studies have found that when the toilet is flushed, the microorganisms in the toilet can be flushed to a height of several meters. These bacteria can float in the air for hours, and finally deposit on bathroom walls and daily necessities such as toothbrushes, mouthwash cups and towels, causing pollution. After these bacteria enter the human body, they may cause diseases.
