technicians have developed a new type of toilet, which uses only 4 liters of water each time, saving one-third to one-half of the water compared with the existing toilet.
Its water tank is filled with water while storing air. The pressure in the water supply pipeline is used to compress the air stored inside, and then the water is pushed into the bedpan at a high speed. Different from the "pull" force of traditional sanitary ware, this new sanitary ware uses "push" force to discharge dirt, which has great impulse, so it can save water.
In fact, other domestic water in the family can also be used to flush the toilet. For example, after the last rinse, the clothes are cleaned, and the water discharged from the washing machine looks relatively clean. It is a pity that it flows directly into the sewer pipe. There is also water like washing face and vegetables, and it would be nice if it could be reused. Wu Hanping, an amateur inventor, developed a set of domestic water reuse device and obtained a national patent. He connected the sink in the kitchen, the basin in the bathroom and the water tank in the toilet to a water storage tank. Clean water from the sink and basin enters the water storage tank for toilet flushing.
