Path 1: Reduce waste outside the water use process.
Reduce the waste closely related to the water use process outside the water use process, that is, avoid the "running, running, dripping and leaking" of water appliances, and close the water appliances in time after using water. These products mainly include ceramic valve-core faucets (commonly known as water-saving faucets, which are "water-saving faucets" distributed to residents' families free of charge by the Beijing Municipal Government), delayed self-closing faucets and flushing valves, and induction sanitary wares. Strictly speaking, these products can't save water, but as long as they don't waste water.
Path 2: Reduce waste in the process of water use.
To provide the most suitable amount of water for a certain water use purpose, that is, to minimize excess water in the process of water use. For example, the flow rate of 4 ~ 6 liters/minute is suitable for general hand washing, but in actual use, the flow rate often reaches 8 ~ 10 liters/minute or even higher, and the excess is waste. There are mainly two kinds of products to save water by reducing excess water in the process of water use: one adopts Korean technology (invention patent and utility model patent have been applied in China at the same time), and the products include WQS water-saving valve, KNT water-saving valve, etc.-It is said that more than 70 million products have been sold in Korea since 1998; The other is its patented technology, and its product name is constant pressure and constant current efficient automatic water-saving valve, referred to as HS water-saving valve.
Path 3: improve water use mode and improve water use efficiency.
Water-saving can be achieved by improving water use methods and improving water use efficiency. Such products include shower nozzle, bubbler, multifunctional shower nozzle, secondary water-saving nozzle (such as shower-bubbler water saver, shower-shower water saver, secondary flush valve), multifunctional water gun and other water-saving products. However, the function of bubbler and shower is single, and the water saving efficiency is not high, so it is impossible to provide the most suitable water use mode for different water use purposes; However, multi-functional shower shower, two-stage shower-bubble water saver, two-stage shower-spray water saver and multi-functional water gun can provide the most suitable water use methods for different water use purposes, with high water saving efficiency, but they all have defects such as large volume and inconvenient operation.
