Water purifier waterway flushing structure

Abstract

The invention relates to a water purifier waterway flushing structure. The waterway flushing structure comprises a water tank, a water pump, a first filter core group, an RO filter core, a second filter core group, an electromagnetic valve and a control module; a water outlet and a raw water reflux inlet are formed in the water tank; the water outlet of the water tank communicates with a water inlet of the water pump; a water inlet, a reflux inlet and a water outlet are formed in the second filter core group; the first filter core group communicates with the RO filter core in series; a water outlet of the RO filter core communicates with the water inlet of the second filter core group, the water outlet of the second filter core group communicates with a water outlet waterway of the water purifier, the reflux inlet of the second filter core group communicates with a water inlet of the electromagnetic valve, a water outlet of the electromagnetic valve communicates with the raw water reflux inlet of the water tank, and a water outlet of the water pump communicates with a water inlet of the first filter core group; the control module is electrically connected with the water pump and the electromagnetic valve. The waterway flushing structure has the advantages that a waterway in front of the RO filter core can be cleaned, a waterway behind the RO filter core can also be flushed, flushing is uniform and clean, drinking is sanitary, and bacteria cannot breed.

Description

technical field [0001] The invention relates to a water channel flushing structure of a water purifier. Background technique [0002] At present, the water path of the water purifier includes a water tank, a water pump, a first filter element group, an RO filter element, a second filter element group and a waste water valve. When the water purifier is flushing, the booster pump starts to work and opens the waste water valve, so as to realize the flushing of the water purifier, but this flushing method can only flush the water path before the RO filter element, and does not flush the water path behind the RO filter element , the flushing is uneven; in addition, because the water path behind the RO filter element cannot be flushed, the water in the water path will breed bacteria for a long time, making it unhygienic to drink. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide a water purifier ...
