Household water purification device

Abstract

The invention relates to the technical field of household water purification, and particularly discloses a household water purification device which comprises a single-flow-channel desalination assembly which comprises a first water inlet and a first water outlet; a pipeline system which comprises a first pipeline, a second pipeline, a third pipeline, a first valve assembly, a second valve assembly, a third valve assembly, a fourth valve assembly and a salt storage assembly; wherein when regeneration influence factors of the single-flow-channel desalination assembly meet first preset conditions, water conveyed by the first pipeline is guided into the single-flow-channel desalination assembly for regeneration through the first valve assembly, the second valve assembly, the third valve assembly and the first water outlet, and when the regeneration influence factors of the single-flow-channel desalination assembly meet second preset conditions, saline water is obtained after the water passes through the first valve assembly and the salt storage assembly; the saline water is guided into the single-flow-channel desalination assembly through the second valve assembly, the third valve assembly and the first water outlet for deep regeneration. The regeneration effect of the desalination assembly can be improved.

Description

technical field [0001] The present application relates to the technical field of household water purification, in particular to a household water purification device. Background technique [0002] With the progress of society and the improvement of people's living standards, people pay more and more attention to the hygiene of their own food and drinking water. At present, tap water is usually treated by chlorination, which can effectively prevent water-borne diseases, but tap water contains salt, impurities, and residual chlorine, etc., and does not meet the conditions for direct drinking. The water needs to be purified before drinking. [0003] In the prior art, household water purification devices often use desalination filter elements to purify tap water to produce clean water that can be directly drunk. However, during the working process, desalination filter elements will absorb ions and impurities in the water, and after a period of use , the desalination filter elem...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, household water purification devices often use desalination filter elements to purify tap water to produce clean water that can be directly drunk. However, during the working process, the desalination filter element will absorb ions and impurities in the water, and after a period of use , the desalination filter element needs to be regenerated. At present, tap water is usually used to regenerate the desalination filter element. Regenerating the desalination filter element through tap water can restore the ion exchange capacity of the desalination filter element to a certain extent. Purification, when the desalination filter element is regenerated by tap water, the ion exchange capacity of the desalination filter element cannot be completely restored, which reduces the purification effect of the desalination filter element and cannot guarantee the water purification effect of the household water purification device
