The water purification system has at least two states, and under the first state, the purified water outlet 21 of the first filter element unit 2 is communicated with the water storage device 1, and the raw water inlet 22 of the first filter element unit 2 is communicated with the water inlet end 4. In this state, raw water flowing into the water purification system from the water inlet end 4 is filtered by the first filter element unit 2 to form purified water, and the purified water flows into the water storage device 1 through the second pipeline 6 to be stored. In the second state, the raw water inlet 22 of the first filter element unit 2 is disconnected from the water inlet end 4, and the raw water inlet 22 of the first filter element unit 2 is communicated with the water storage device 1. In this state, when the user does not need to output the purified water from the water storage device 1, the purified water from the water storage device 1 may be input to the raw water inlet 22 of the first filter element unit 2 through the first pipeline 5, so that the raw water side of the first filter element unit 2 is washed and the raw water of the raw water side of the first filter element unit 2 is replaced with high quality purified water, compared to the prior art, the purified water prepared by the first filter element unit 2 stored in the water storage device 1 is high quality purified water, and no waste water is mixed when the raw water side of the first filter element unit 2 is washed, so that the quality of the purified water replacing the raw water of the raw water side of the first filter element unit 2 can be effectively ensured, even if the water purification system is left without outputting purified water for a long time, the high quality purified water of the raw water side slowly permeates the membrane of the first filter element unit 2 to reach the purified water side, it is still high quality clean water, and when restarting the water use, this part slowly permeates the high quality clean water that reaches the clean water side of the membrane of first filter element unit 2 and is exported first, and it can not cause the problem that TDS value appears rising when beginning the water use all the time, and the effect is more excellent, and under the different circumstances of the time of putting for a long time of water purification system, the TDS value of the water when restarting the water use is better than the TDS value under the prior art.
As a possibility, the water storage device 1 has a heating device 11 for heating the water. The heating mechanism 11 can heat the purified water stored in the water storage device 1 to a set temperature required by a user.
