Abstract

The water purification device provided by the invention comprises: an RO filter element comprising a first water inlet and a first water outlet; the first branch is connected with the first water inlet and is suitable for supplying water to the RO filter element; the first filter element comprises a second water inlet and a second water outlet; the second branch is connected with the second water inlet and the first water outlet and is suitable for supplying water to the first filter element; and one end of the flushing branch is communicated with the second branch, the other end of the flushing branch is provided with a flushing outlet, and the flushing branch is further provided with a first switch piece suitable for controlling on-off of the flushing branch. By arranging the flushing branch, the first switch piece and the flushing outlet communicated with the outside, when the RO filter element needs to flush protection liquid, the first switch piece can be turned on, so that flushing water containing the protection liquid is directly discharged without passing through the first filter element, the first filter element is prevented from being damaged by the protection liquid, and the protection on the filtering performance of the first filter element is realized; and moreover, the structure is simple and easy to realize, and the cost of transforming the original waterway is reduced.

Description

technical field [0001] The invention relates to the technical field of water purification equipment, in particular to a water purification device. Background technique [0002] At present, due to the increasingly serious water quality problems and the gradual improvement of people's living standards, water purifiers have gradually become one of the important household appliances in life. The RO filter element in the water purifier that filters water through the reverse osmosis principle is generally a wet membrane structure, and there is a protective liquid in the diaphragm. When using the filter element of the whole machine, the protective liquid in the diaphragm needs to be rinsed. Normal use. [0003] In the existing membrane protection liquid flushing scheme, the protection liquid is usually flushed out of the RO filter element by connecting the water inlet branch to the RO filter element, and passes through the filter element (usually carbon rod or activated carbon) do...
