The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

A water purification system 1 according to an embodiment of the present invention is described below with reference to the accompanying drawings.

As shown in fig. 1 to 5, a water purification system 1 according to an embodiment of the present invention includes a water purification container 10, a water purification branch pipe 20, a main filtration cartridge 30, an electrolysis branch pipe 40, an electrolysis device 50, and a switching device.

The water purification container 10 communicates with a purified water outlet 15 of the water purification system 1. The water purification branch pipes 20 are respectively communicated with the water source 61 and the water purification container 10. The main filtering cartridge 30 is connected to the clean water branch pipe 20. The electrolysis branch pipes 40 are respectively communicated with the water source 61 and the water purification container 10. The electrolysis unit 50 is connected to the electrolysis branch 40. The switching device is switchable between a sterilization state and a water purification state, the switching device communicates with the water source 61, the electrolysis device 50 and the water purification container 10 in the sterilization state, and communicates with the water source 61, the main filtration cartridge 30 and the water purification container 10 in the water purification state.

Specifically, when the water purification system 1 receives a sterilization instruction input by a user or performs a sterilization function according to a periodic timing sterilization instruction, the switching device is switched to the sterilization state, the electrolysis branch pipe 40 is communicated with the water source 61, the electrolysis device 50 and the water purification container 10, the electrolysis device 50 is started, water at the water source 61 flows to the water purification container 10, the electrolysis device 50 electrolyzes the flowing water to electrolyze water molecules into hydrogen ions and oxygen ions and further generate electrolyzed water capable of sterilization, the water purification container 10 is sterilized, then the operation of the electrolysis device 50 is stopped, after a predetermined time, the water purification container 10 is emptied, the switching device is switched to the water purification state, the water purification branch pipe 20 is communicated with the water source 61, the main filtration filter element 30 and the water purification container 10, water at the water source 61 is re-replenished to the water purification container 10 after being filtered by the main filtration filter element 30, for normal use by the user.

When the water source of the water purification system 1 is a tap water source, the positive and negative electrodes decompose water molecules into hydrogen ions and oxygen ions during electrolysis, the oxygen ions as anions react with other surrounding water molecules to generate hydroxyl (OH-), and at the moment, the sodium hypochlorite is also decomposed into HCL +, O-during electrolysis due to the fact that the tap water contains a small amount of sodium hypochlorite, and dissolved oxygen anions and hydrogen peroxide sterilizing substances are generated, so that water is sterilized and sterilized water is produced.

The hypochlorous acid generated after electrolysis can not only act on the cell wall of bacteria, but also permeate into the bacteria to oxidize organic molecules such as mycoprotein, nucleic acid, enzyme and the like, and destroy the composition system to kill microorganisms. And hypochlorous acid can generate active hydroxyl during the reaction process; the active oxygen can also generate hydrogen peroxide under the condition of an oxidation-reduction point to further generate active hydroxyl, and the active hydroxyl is a strong oxidant, has decomposition and inactivation effects on bacterial accounting, protein and metabolic enzyme, and is very similar to the sterilization mechanism of neutrophilic granulocytes in organisms. After the acidic oxidation point acts on water, the permeability of bacterial cells is enhanced, the cells swell, and bacterial spores are killed due to overflow of contents.

According to the water purification system 1 of the embodiment of the invention, the water purification branch pipe 20 and the electrolysis branch pipe 40 are arranged, and the switching device is arranged to control the water at the water source 61 to flow to the electrolysis device 50 or to flow to the main filtering filter element 30.

Therefore, the condition that the sterilization capacity of the electrolyzed water is greatly reduced after being filtered by the filter element can be avoided, the sterilization of the subsequent pipelines and containers of the filter element is facilitated, and the sterilization effect of the water purification system 1 is ensured.

In addition, as the water purification branch pipes 20 and the electrolysis branch pipes 40 are switched by the switching device to realize the switching of the sterilization and water purification functions, water at the water source 61 does not pass through the electrolysis device 50 first during the water purification function, so that the water flow during the water purification can be ensured, and the water production efficiency of the water purification system 1 can be ensured.

In addition, because the water at the water source 61 will not pass through the electrolytic device 50 first during the water purification function, the attachment and accumulation of impurities at the electrolytic device 50 can be slowed down, the electrolytic effect of the electrolytic device 50 is ensured, and the worry of the user about the precipitation of harmful substances after the purified water passes through the electrolytic device 50 can be avoided.

Further, because water purification function and electrolysis function pass through auto-change over device switches, rivers flow through different water routes respectively when the electrolysis function with the water purification function, can avoid the electrolytic water to influence the life of follow-up filter core, guarantee the life of filter core, avoid the frequent change of filter core, travelling comfort when improving the user and using.

the water purification system receives a sterilization instruction and enters a sterilization state, the purified water on-off valve is closed, the electrolysis on-off valve is opened, the switching valve is communicated with the flushing branch pipe, so that a water source, the electrolysis device, the post-positioned filter element and the purified water container are communicated, and the electrolysis device is controlled to operate;

after the water in the water purification container is drained, the switching valve disconnects the washing branch pipe, so that a water source, the electrolysis device and the water purification container are communicated, and the electrolysis device is controlled to operate;

after a preset soaking time, draining the water purifying container;

Therefore, the sterilization water can be controlled by the reversing valve to sterilize the post-positioned filter element or directly sterilize the water purifying container, and the post-positioned filter element and the water purifying container are sterilized respectively.

Optionally, the predetermined soaking time is 20-40 minutes. Therefore, the soaking time can be ensured, the sterilization effect can be ensured, and the overlong waiting time of a user can be avoided.

Further, the predetermined draining time is 40-80 seconds. Therefore, the emptying of the water tank can be ensured, users are prevented from taking unfiltered water, and the waiting time of the users can be reduced.
