Classification of household water purifier

The water purifier company can be divided into two categories according to the pipeline design level: gradually tightened water purifier and self-cleaning water purifier. The traditional water purifier is a gradually tightened water purifier. Its internal pipeline is designed to be loose before and tight after the filter element. It is composed of PP melt blown filter element, granular carbon, compressed carbon, RO reverse osmosis membrane or ultrafiltration membrane, and post activated carbon. Generally, these five stages are connected one by one. The intercepts are deposited in the filter element and need to be removed and washed manually regularly to ensure the normal operation of the machine.

The other is a more advanced self-cleaning water purifier. Two channels are designed inside the machine, and a washing water channel is added. As the washing water of ordinary domestic water passes through the channel, it will wash the filter element inside the machine, especially the raw water side of the membrane filter element, to achieve self-cleaning. The first and last two sections of water that originally flowed off when the washing faucet is opened and closed will be used to intercept the dirt Timely and fast discharge, the structure design is reasonable, which saves the trouble of manual removal and cleaning, avoids the re pollution of the mechanism itself, and reduces the energy consumption cost. The self-cleaning water purifier adopts the new principle of mass separation and circulation. Impurities are removed at any time. The inner core is clean to avoid secondary pollution.

However, please note that the self-cleaning water purifier is different from the automatic blowdown water purifier, computer automatic flushing water purifier and automatic backwashing water purifier seen on the market. The former is self-cleaning of the whole machine, that is to say, it has certain self-cleaning function for all filter elements inside the machine; the latter only flushes one filter element instead of the whole machine. Generally speaking, the self-cleaning water purifier is equivalent to installing a garbage disposal device on the pipeline, so the dirt can be removed at any time without staying in the machine. However, the traditional non self cleaning water purifier is equivalent to using multiple trash cans in the room, and the dirt is usually temporarily stored in the machine, so it is necessary to regularly drain, dismantle and wash and change the filter element frequently.

Intelligent water purifier refers to the water purifier equipped with LED display screen, with voice function, temperature monitoring control, temperature alarm, water level control, water level monitoring alarm and other functions.
