Water purifiers can be divided into gradual tightening water purifiers and self-cleaning water purifiers according to pipeline design grades. The traditional water purifier is a gradually tightening water purifier. Its internal pipeline is designed as a loose filter element at the front and a tight filter element at the back. It consists of PP melt-blown filter element, granular carbon, compressed carbon, RO reverse osmosis membrane or ultrafiltration membrane, and post-activated carbon. Usually, these five stages are connected end to end.

The working principle of Infinitus Enjoying Youle Water Purifier;
The first stage: PP cotton: remove all kinds of visible objects/dust and impurities from tap water.
Second and third stages: Pre-activated carbon: The third stage of some low-grade water purifiers is also PP cotton, and activated carbon removes chlorine and organic impurities. It can also absorb the peculiar smell, color and smell produced by organic matter in water.
The fourth stage: ultrafiltration or reverse osmosis membrane: the membrane can remove bacteria, viruses and spores from water.
Stage 5: Post-activated carbon device: further improve the taste and remove the odor.
Most water purifiers adopt a progressive structure based on the screen-blocking filtering principle, which is composed of multi-stage filter elements connected in series from end to end. The precision of filter elements is arranged in sequence from low to high, so that multi-stage filter elements can share the trapped dirt, reduce the number of filter element blockage, manual sewage discharge and disassembly and washing, and prolong the cycle of replacing filter elements.
There is also a new design idea, that is, the self-cleaning structure based on the principle of mass circulation. Its design idea is no longer to provide as much space as possible, but to separate a small part of clean water by the principle of mass separation, and at the same time, to make the raw water circulate as usual as much as possible, so that pollutants can be taken away with the water in time, so as to achieve the purpose of running water without rot.
In this way, pure water can be obtained without or easily depositing dirt in the machine, which avoids secondary pollution, greatly reduces the loss of filter elements, and has better water quality, safety, energy saving and low carbon. This new principle of self-cleaning water purifier won the gold medal in the 7th International Invention Exhibition. It has a structure of one inlet and two outlets.
It improves the structural disadvantages of traditional water purifier, such as one inlet and one outlet, and the impurity concentration of raw water accumulates higher and higher in the machine, and finally becomes sewage. Therefore, the self-cleaning water purifier has no concept of sewage and sewage water purifier, and it is replaced by washing water. With the improvement of living standards, the popularity of water purifiers will become wider and wider, and new technology products will better meet people's needs.
Choose a cost-effective one:
1. Different water purifier structures have different water purification effects. Generally speaking, the primary filtration water purifier is simple in structure, mainly made of activated carbon, with limited filtration capacity, and can only be used for coarse filtration. It is best to boil the filtered water and drink it. Most of the primary filtration water purifiers belong to low-grade water purification products, and the price of each one ranges from 10 yuan to 150 yuan.
2. Multi-stage filtration water purifier. This water purifier has two stages of coarse filtration and a set of fine filtration. The fine filtration mostly adopts hollow fiber filter element, and the filtered water can be directly drunk. Multi-stage filtration water purifier is a mid-range water purification product, the price is between 300-500 yuan, which is acceptable to the working class and widely used in families.
3.UF ultrafiltration nanofiltration membrane water purifier is composed of multi-stage pre-filtration and ultrafiltration membrane, which can intercept most bacteria and harmful substances. It is the most commonly used direct drinking water purification device in the market at present. At the same time, mineral trace elements beneficial to human body are retained, and the advantages of KDF and activated carbon are utilized to effectively inhibit the growth of bacteria and fungi in water and remove abnormal colors and odors.
Ensure that the filtered water can be used safely and healthily. Moreover, the water output is relatively large, and the waste water discharge is small, so it is faster and more convenient to use in the family kitchen without waiting for a long time. It belongs to mass consumer goods. According to different requirements, the price of each set ranges from 5,000 yuan to 200 yuan.
4.RO reverse osmosis pure water machine is the most ideal water purification product for treating rural water and groundwater. It has three-stage pre-filtration, one-stage reverse osmosis membrane precision filtration and one-stage post-filtration.
The filtered water contains no bacteria, viruses, heavy metals, pesticides, organic matter, minerals and strange colors. It's pure water. You can drink it without heating. This reverse osmosis pure water machine belongs to high-grade water purification products, and the price of each set is between 1000 yuan and 5,000 yuan.
5. Self-cleaning water purifier, applying the principle of "running water does not rot, household shaft does not rot", the most important thing of water purifier lies in the way of pipeline design and garbage disposal.
