Embodiment Construction

[0026] The technical solution of the present invention will be described below in conjunction with the accompanying drawings. Apparently, the accompanying drawings describe only a part of the present invention rather than all embodiments.

[0027] A filtering device provided by the present invention is composed of at least two filters with different filtering precisions connected in parallel, and each filter has two water outlets, a clean water outlet and a concentrated water outlet, and two concentrated The filtered water from the water outlet is mixed. The filtration accuracy here refers to the different technical parameters of the filtered water, such as hardness value, TDS value and so on. It does not specifically refer to its specifications or models. For example, the filter A9 may be a plurality of certain filter elements connected in series, while the filter B10 is a single certain filter element, which also meets the requirements. In reality, the water parameters filt...

Abstract

The invention discloses a filtering device and a water purifier employing the filtering device. The filtering device includes at least two filters with different filtering precisions, wherein the two filters are connected in parallel, and each filter is provided with two water outlets, i.e. a purified water outlet and a concentrated water outlet. The water purifier includes a water inlet device, a primary filtering device, a water boosting device and a secondary filtering device which are arranged on a water circuit of the water purifier in sequence, wherein the filtering device disclosed by the invention serves as the secondary filter device. The invention has the benefits that drinking water that can totally meet the needs of human bodies can be obtained through the reverse osmosis devices with the different filtering precisions, and the water recovery rate is also greatly increased.

Description

technical field [0001] The invention relates to the technical field of water filtration and water purification, in particular to a water purifier with two sets of reverse osmosis membrane devices connected in parallel. Background technique [0002] Drinking water that is beneficial to the human body should have the following characteristics: 1. No pollution, no pathogenic bacteria, heavy metals and harmful chemicals; 2. Moderate hardness; 3. Contain natural minerals and trace elements needed by the human body; 4. pH The value is slightly alkaline. Medically confirmed: the pH of water will not directly affect human health. However, to retain the diversity of minerals and trace elements in the raw water in an appropriate amount, the pH value of the water must be neutral and slightly alkaline, commonly known as "weak alkaline water". [0003] The goal of the water purifier is to convert tap water into drinking water that meets the above goals. The embarrassment of the existin...
