Description

Water purifying device

Technical Field

The utility model relates to an environmental protection field specifically is a purifier.

Background

With the development of economy and the improvement of living standard of materials, people have higher and higher requirements on the quality of drinking water. Tap water entering thousands of households is generally life drinking water produced in a tap water plant through flocculation, precipitation, filtration and chlorine disinfection processes. Despite the purification and disinfection of many processes, the drinking water for consumer use still contains some chemical substances such as silt, micro humus, soluble organic substances and disinfectants due to the purification efficiency and the artificial addition of disinfectants. In addition, along with the lapse of time, secondary pollution caused by old and aged urban water distribution and distribution pipe networks is increasingly shown, and the most common pollution sources are rust, silt, microorganisms and the like. Therefore, the use of a suitable household water purifier is undoubtedly an economical, convenient and fast way for obtaining safe and healthy drinking water at home.

The tap water purifier refers to a miniature water purifying device/equipment which is directly installed and hung on a household tap. The faucet water purifier is popular with consumers due to the advantages of low price, simple installation and maintenance procedures, rapid effect of improving water quality and the like. Ceramic and composite filter material technologies are relatively commonly used water purification technologies. The steps of using the technology to treat sewage are as follows: directly leading the sewage into the hollow shell to make the sewage directly contact with the filter element.

However, when sewage enters the housing, the tap water automatically selects the shortest path to flow through the filter element under the action of pressure and gravity, the lowest part of the filter element (the water treatment material close to the water outlet firstly adsorbs harmful substances, and the lowest water treatment material also firstly reaches the saturated adsorption capacity and loses efficacy, after the water treatment material below the filter element is used for a period of time, the water treatment material below the filter element can reach the state of adsorption saturation in advance, and the water treatment material above the filter element hardly has the filtering effect, after the water treatment material below the filter element is blocked by insoluble substances in water, a water purification site of the water treatment material with the adsorption effect can gradually move upwards, after the tap water is purified, the purified water still needs to flow through the water treatment material below the filter element to flow out, and further secondary pollution is caused, meanwhile, because the water treatment material below the filter element is blocked, it is also quite likely that the net water flow will be too small or blocked.
