Abstract

The invention discloses a composite filter element, a water purifier and a filter element cleaning method, and the water purifier comprises a first filter element, a second filter element, a third filter element and a booster pump. And a first cleaning agent is arranged in the first filter element. The first water inlet end of the second filter element is communicated with the first water outlet end of the first filter element through a pressurizing pipeline, and the second filter element is also provided with a concentrated water outlet end and a purified water outlet end. A second cleaning agent is arranged in the third filter element, the second water inlet end of the third filter element is communicated with the purified water outlet end, and the second water outlet end of the third filter element is communicated with the first water inlet end through a backflow pipeline. And the booster pump is arranged on the booster pipeline. According to the water purifier provided by the embodiment of the invention, when the first filter element is replaced, the first cleaning agent can be fed into the second filter element to soak and wash the second filter element, and the second filter element is cleaned for the first time; when the third filter element is replaced, the second cleaning agent is fed into the second filter element to clean the second filter element for the second time, the second filter element does not need to be disassembled, a cleaning solution does not need to be prepared, and the filter element cleaning effect is good.

Description

technical field [0001] The invention belongs to the technical field of water purification equipment, in particular to a composite filter element, a water purifier and a filter element cleaning method. Background technique [0002] With the improvement of material living standards, more and more families pay attention to the quality of drinking water, and purchase water purification equipment to purify tap water. When the water purification equipment is used in different regions, the raw water conditions vary widely, so the service life of the filter element in the water purification equipment is not the same. [0003] Most of the core filter components of existing water purification equipment are reverse osmosis membranes (RO membranes), and other related components include non-woven filter layers, polypropylene filter layers, activated carbon filter elements, water pumps, and pressure switches. Calcium and magnesium ions, sediment, organic matter and other substances conta...
