Detailed Description

The present invention will be further described with reference to the following description and examples, which include but are not limited to the following examples.

As shown in FIGS. 2 to 3:

a water purification system comprises a water inlet electromagnetic valve 1, a first filtering device 2, a second filtering device 3, a third filtering device 4, a water tank 5, a pressure switch 6, a water tap 7 and an electric submersible pump 10 which are arranged in the water tank 5 and connected with the pressure switch 6 through pipelines in sequence along the water flow direction; the submersible electric pump is started to pump the purified water in the water tank, so that a certain water pressure is generated by the water in the pipeline, and the pressure switch 6 is opened and flows out from the water faucet 7.
