Self-cleaning long-service-life household water purifier

Abstract

A disclosed self-cleaning long-service-life household water purifier comprises a water pump and an air pump, a main water pipe is arranged in the outer side of the water pump, a first auxiliary water pipe is arranged on the outer side of the main water pipe, and a flow meter is arranged on the outer side of the main water pipe; and a filtering tank I, a filtering tank II, a filtering tank III and a filtering tank IV are arranged between the water pump and the air pump. According to the self-cleaning long-service-life household water purifier, through mutual cooperation of first to fourth filtering barrels, four-stage filtering can be achieved, it is guaranteed that the water purifying effect of safer drinking is achieved, backwashing of the first filtering barrel and the fourth filtering barrel is achieved through reverse flushing of water flow and air flow, desorption of the second filtering barrel and the third filtering barrel is realized through thermal desorption and salt desorption, so that impurity molecules adsorbed on the surface of a filter element material fall off, the self-cleaning effect is realized, the service life of the filter element is prolonged, the filter element material is recycled, and the filter element replacement frequency is reduced while the filtered water is safer and healthier.

Description

technical field [0001] The invention relates to the technical field of household water purifiers, in particular to a self-cleaning long-life household water purifier. Background technique [0002] Water is the source of life. According to statistics, 80% of all diseases and deaths in the world are related to drinking water sources. The safety and cleanliness of drinking water has become a hot issue of global concern. my country is also paying more and more attention to people's drinking water issues. , Household water purifiers gradually entered the homes of ordinary people. [0003] However, most of the existing household water purifiers only have a single filter structure, which cannot effectively eliminate impurities in the water, and the water purification ability is relatively poor, and the existing household water purifiers cannot automatically clean the household water purifiers. The filter element needs to be replaced, which increases the cost of use and also reduces...

Problems solved by technology

[0004] The purpose of the present invention is to provide a self-cleaning long-life household water purifier to solve the problem of most of the existing household water purifiers in the above-mentioned background technology. Only a single filter structure is provided, which cannot effectively eliminate impurities in the water. The ability is poor, and the existing household water purifiers cannot realize the automatic cleaning of household water purifiers, and often need to replace the filter element, which increases the cost of use and also reduces the environmental protection of household water purification. The design has defects and is not easy to use The problem
