The structure of the flush toilet is very simple. In the 16th century, the Englishman John Harrington invented the flush toilet. In 1775, a London clockmaker named Alexander Cumming improved Harrington's design and invented
He invented a valve device, developed a flush toilet, and obtained a patent for the first time.
As an industrial designer, Li Zhi certainly knows the structure of the flush toilet. For Li Zhi, it is very simple to draw the structural diagram of the flush toilet.
The water tank switch of the toilet is very simple. With the design drawing drawn by Li Zhi, you can basically find a qualified coppersmith to make it. Although there is no plastic in this era, the use of copper can replace plastic.
The ceramic bucket body of the toilet is not difficult to build. In this era, the Ming Dynasty has been able to create all kinds of ingenious porcelain, and firing the toilet bucket body is also a piece of cake. Li Zhi found Cai Huaishui, gave him the design drawings, and asked him to find some
A reliable porcelain maker makes the barrel body.
There were local porcelain makers in Tianjin, and it only took Cai Huaishui seven days to find someone to make three barrel bodies.
Li Zhi dug a pit in the glass workshop, assembled the burned toilet barrel and the copper mechanism made by the coppersmith and placed them on the pit. The first flush toilet in Ming Dynasty was born. Li Zhi threw a few balls
Put the waste paper into the toilet, press the button and flush, and the paper ball will be flushed into the puddle under the toilet.
Although there was no running water in this era, well water was easy to obtain. Every ten villas in Fanjiazhuang had a well dug. Before using the toilet, the user needs to carry a bucket of water and pour it into the ceramic bucket on the top of the toilet. Because manual water filling is required
, the float ball in the toilet tank does not need to be replaced. This float ball is the most complicated part of the entire toilet technology. Not producing the float ball can save a lot of costs.
For flush toilets, the fixation of the toilet is very important. The pipes must be aligned with each other. The cement produced by Li Zhi comes in handy at this time. Just use cement to fix the toilet barrel in the toilet.
, there is no problem of the barrel being moved and unable to be used.
After mass production of this new type of toilet, priority will be given to selling it to the people of Fanjiazhuang.
There are septic tanks dug under the villas in Fanjiazhuang, and there is no need to renovate the sewers to install flush toilets. Li Zhi gave a preferential price to the people of Fanjiazhuang: as long as you buy the flush toilet with the waist card of a Fanjiazhuang resident, the price is as low as 20 taels. This price is still
Including installation fees and cement material fees, as long as you pay two taels of silver and make an appointment, the construction team will come to install flush toilets for residents.
This is basically the cost price. Li Zhi hopes to use flush toilets to improve the sanitary conditions in Fanjiazhuang, and he does not expect this new thing to make much money for himself.
In fact, for the residents of Fanjiazhuang, installing toilets can not only eliminate the stench of the toilet, but also allow the common people to have an extra small room - there was a dedicated room in the Fanjiazhuang villa designed by Li Zhi.
Bathhouse. Nowadays, after the toilet is equipped with a flush toilet, the toilet is no longer dirty and smelly. People can open up a bathing space in the toilet, and the free bathhouse can be used as a small room.
Spending two taels of silver can not only improve the sanitary conditions, but also free up a small room, which is a very cost-effective deal. The original bathroom can be used to store sundries and can also be used as a children's bedroom.
After Li Zhi installed the toilet for Huan Lide, the Huan family immediately got rid of the stench of the toilet and had an extra room. After the people of Sanheng Street where the Huan family was located visited the Huan family's new toilet, they immediately spread the benefits.
Out. People in Fanjiazhuang rushed to the toilet store in Fanjiazhuang to pay and make reservations. Within a few days, almost all the people in Fanjiazhuang had registered to buy.
The situation in private houses in other parts of Tianjin is different. Most of the houses in Tianjin do not have septic tanks. To install a flush toilet, you have to temporarily dig a septic tank, which is a huge amount of work. Without seven or eighty taels of civil engineering wages, it is impossible to install a flush toilet.
Therefore, in Tianjin Acropolis and other prefectures and counties, flush toilets have not yet become popular.
But Li Zhi believed that with the example set by the people of Fanjiazhuang, the people of the Ming Dynasty who liked to follow the trend of new things, especially the wealthy people among them, would gradually install flush toilets.
Li Zhi was no longer prepared to keep this toilet a secret. It was too easy to copy. Unless the entire Ming Dynasty had a patent system to protect Li Zhi’s intellectual property rights, Li Zhi would not be able to stop the counterfeiters. Moreover, Li Zhi was now the Duke of Tianjin.
The magnanimity is no better than before. Li Zhi hopes that craftsmen from other places will learn this new type of toilet as soon as possible. He hopes that all people in the Ming Dynasty will use this type of flush toilet to improve their living and sanitary conditions.

Emperor Zhu Youjian stood in the newly built "bathroom" of Qianqing Palace, marveling at the toilet installed in the bathroom as a tribute from Li Zhi.
The bathroom in Qianqing Palace is very large and elegant.
A few days ago, Li Zhi sent craftsmen from Tianjin to dig a septic tank behind the Qianqing Palace. After the septic tank was dug, the craftsmen sealed it with cement, leaving only a chimney made of white marble slabs for exhaust.
In the Qing palace, craftsmen built a wall with cement and installed a flush toilet to create a toilet.
According to Li Zhi, this toilet with a flush toilet is clean and hygienic and should be called a "bathroom". Zhu Youjian guessed that this meant washing hands after taking out the toilet, so he called the toilet a "bathroom".
There was originally no toilet in the Qianqing Palace. The toilet used by the emperor was called the "official room" and was kept by a special eunuch. When needed, it was transferred to the "official room" and was not placed in the palace at ordinary times. Compared with Li Zhi's toilet, the original "official room" was used
"Official room" seems unhygienic and inconvenient.
Zhu Youjian looked at the bathroom in the Qianqing Palace with joy and said with a smile: "I won't have to use the embarrassing 'official room' anymore."
Zhu Youjian found a piece of waste paper, crumpled it into a ball and threw it into the toilet. As soon as he pressed the button on the toilet sink, he saw well water pouring from the sink into the toilet, wrapping the paper and flushing it away.
Zhu Youjian smiled and said: "Okay, it really works! With such a bathroom, I don't need others to take care of my private matters, and the embarrassment in it is eliminated. It's really a good thing."
Wang Chengen blinked his eyes and asked: "Your Majesty, how did the Duke of Jin invent so many new things? Where did he learn them? Even if Lu Ban comes back, I'm afraid he won't be able to match the skillful craftsmen of the Duke of Jin."
Governor Zhu You said: "I don't know why Duke Jin can invent so many new things. But I know that Duke Jin is loyal. For such a good thing as a flush toilet, which is clean and hygienic, Li Zhi was the first to think of it.
I installed it, and its loyalty can be seen."
Wang Chengen cupped his hands and said, "Your Majesty, Sheng Ming."
Governor Zhu You said: "Ask the craftsmen of Duke Jin not to leave. I will not be polite to Duke Jin. I will ask him to install toilets in the palaces of Prince Ding, King Ding, King Yong and King Mou. There are also two
