This can be traced back to the "Trojan Horse" in Ouyang Xiu's Return to the Field II in the Northern Song Dynasty, which is the earliest written record of toilets. As for the history of toilets, we have to start from the Han Dynasty. According to Xijing Miscellanies, the court of the Han Dynasty was made of jade and was held by the emperor's attendants for the convenience of the emperor at any time. This kind of "tiger" is a special appliance called toilet and urinal by later generations, and it is also the predecessor of toilet. It is said that this kind of "nothing" was also invented by great-grandfather Liu Bang with the crown of Confucian scholars as a drowning device.
There is another saying about the invention of "nothing", which is also related to the emperor. According to legend, in the Western Han Dynasty, Li Guang, a flying general, shot and killed a crouching tiger, making people cast a copper drowning device in the shape of a tiger and put it in urine to show their contempt for the tiger. This is the origin of the name "tiger". However, when the emperors of the Tang Dynasty sat in Long Ting, because one of their ancestors was called Li Hu, their disrespectful address was changed to "beast" or "girl", and later they were commonly called "toilet" and "urinal".
Toilet cleaning:
wash
1) The toilet seat should be cleaned with more bacteria.
32% of toilets are interested in Shigella dysenteriae, and one Shigella dysenteriae named "Songnei" has lived on the toilet seat for 17 days. Another experimental report also pointed out that 654.38 billion polio viruses were thrown into the toilet, and 3,000 viruses spilled on the toilet seat. At the same time, many people like to put a flannel pad on the toilet in winter, which makes it easier to absorb, retain and excrete pollutants and spread diseases more easily.
The place with such serious pollution is the place with the closest contact with human skin, which needs to be cleaned emphatically and wiped with diluted household disinfectant every one or two days. As for the cloth gasket, it is best not to use it. If you must use it, you should always clean and disinfect it. If you have the conditions, you might as well change to a toilet with antibacterial function and splash-proof design.
2) Clean the dirt in the toilet in time.
Toilets are easily polluted by urine stains, feces and other dirt. If you find that there are still traces after flushing, you must clean it with a toilet brush in time, otherwise it will easily form macular spots and breed mold and bacteria. In addition to being close to the nozzle, the water outlet at the inner edge of the toilet and the outer side of the base are places where dirt is hidden. When cleaning, first lift the toilet seat and spray it with toilet cleaner. After a few minutes, brush it thoroughly with a toilet brush, preferably with a fine brush, so as to better clean the depth of the inner edge of the toilet and the nozzle. Then scrub the base and other gaps.
3) Try not to set a wastebasket beside the toilet.
At ordinary times, you can also put a gradually dissolving automatic toilet cleaner in the water tank or hang a wall-mounted disinfection plug, so as to achieve the effects of cleaning, descaling, disinfection and sterilization by flushing each time.
Most families will set a wastebasket next to the toilet to store used toilet paper, but this will cause bacteria to spread with the air, because few people can clean it at any time, at least for a day or two, and the longer it takes, the more bacteria there will be.
Toilet paper should be thrown into the toilet and washed away. As long as it is not too thick and tough, toilet paper can generally soften quickly in water, so don't worry about clogging. When necessary, just prepare a sanitary bag, there is no need to set up a waste paper basket. If you must use it, you should also choose a cover to prevent the spread of bacteria and dispose of used toilet paper in time.
4) The toilet brush should be kept clean and dry.
Toilet brush is the hero to keep the toilet clean, however, if you don't pay attention to cleaning and drying, it will also become a source of pollution. Every time you brush dirt, it is inevitable that the toilet will be stained with dirt. It is best to flush the water again, rinse it clean, drain it, spray disinfectant, or soak it in disinfectant regularly and put it in a suitable place.
Experts suggest that toilet brushes should be hung up, not just in corners or closed containers.
5) that importance of clean toilets
Professor Yu Qingfu from the School of Public Health of Fudan University pointed out that the survey found that 32% of toilets had Shigella dysenteriae. Another experimental report also pointed out that 654.38 billion polio viruses were thrown into the toilet, and 3,000 viruses spilled on the toilet seat. At present, most families go to the toilet, wash and shower in the bathroom, such as toothbrushes, mouthwash cups and towels. They are all in the same room as the toilet, so they are naturally vulnerable to bacterial pollution. The bacteria in the toilet mainly come from excrement and dirt and bacteria left on the toilet wall for a long time due to improper cleaning.
