The reverse osmosis filter element 2 can finely filter the water filtered by the front filter element 1, and because the aperture of the reverse osmosis membrane (RO membrane) of the reverse osmosis filter element 2 is one million of that of a hair, water molecules and part of mineral ions with small particle sizes are almost only allowed to pass through, therefore, the water filtered by the reverse osmosis filter element 2 only contains part of mineral ions with small particle sizes, bacteria and viruses can be filtered, and the purified water taken by a user from the outlet end 102 is cleaner.

It should be noted that the concentration of the water in the reverse osmosis filter element 2 is lower than that of the water filtered by the pre-filter element 1, and in order to ensure that the water filtered by the pre-filter element 1 can flow into the reverse osmosis filter element 2, a second booster pump 8 is arranged between the pre-filter element 1 and the reverse osmosis filter element 2. Through setting up second booster pump 8, can go into reverse osmosis filter element 2 with the water pump of high concentration to carry out the fine filtration to water.

The existing hydrogen-rich water is provided, which can improve human immunity after long-term drinking and has the function of oxidation resistance, therefore, part of the water purifier in the prior art still comprises an electrolysis module, which is used for electrolyzing purified water to generate hydrogen, and the hydrogen is dissolved in the purified water to form the hydrogen-rich water. However, in the prior art, the electrolysis module is usually disposed behind the reverse osmosis filter element 2, and the purified water filtered by the reverse osmosis filter element 2 contains almost no substances, so that the conductivity of the purified water is extremely low, the electrolysis rate is slow, and the hydrogen production efficiency is low.

In order to solve the above problem, as shown in fig. 1, the water purifier provided in this embodiment further includes an electrolytic component 3 and a first booster pump 4, wherein an inlet of the electrolytic component 3 is communicated with an outlet of the pre-filter 1 through a first branch pipe 20; the outlet of the electrolysis component 3 is communicated with the main pipeline 10 through a second branch pipeline 30, and the connection point of the second branch pipeline 30 and the main pipeline 10 is positioned between the outlet end 102 and the clean water outlet of the reverse osmosis filter element 2; the first booster pump 4 is provided on the second branch line 30, and the first booster pump 4 is configured to pump gas generated by electrolyzing water by the electrolysis part 3 into the water filtered by the reverse osmosis filter cartridge 2. The electrolytic component 3 is arranged at the rear end of the front filter element 1, raw water is subjected to coarse filtration and then enters the electrolytic component 3 for electrolysis, at the moment, more substances and more electrolysis-capable ions are generated in the water, and the preparation efficiency of hydrogen can be effectively improved; the outlet of the electrolysis component 3 is communicated between the reverse osmosis filter element 2 and the outlet end 102, the second branch pipeline 30 is provided with the first booster pump 4, and the first booster pump 4 can directly pump the gas generated after electrolysis into the purified water to form hydrogen-rich water for users to take. The hydrogen production efficiency of the water purifier is high, the waiting time of a user is saved, and the user experience is improved. It should be noted that the proportion of hydrogen in the gas generated by the electrolysis of water by the electrolysis unit 3 is large, and when the gas is mixed with pure water, the gas with high hydrogen content is dissolved in the pure water, not the pure hydrogen.

Optionally, a check valve 34 is further provided on the second branch line 30, so that the water in the main line 10 can be prevented from flowing back into the electrolytic component 3 through the second branch line 30.

In order to solve the above problem, the electrolytic component 3 further comprises a first detecting member 33 and a first control valve 32, wherein the first detecting member 33 can sense the upper liquid level signal of the electrolytic cell 31; the first control valve 32 is disposed on the first branch line 20, and when the upper liquid level signal is triggered, the first control valve 32 is closed. When the electrolytic water in the electrolytic cell 31 is at the highest liquid level of the electrolytic cell 31, an upper liquid level signal is triggered, the first detection part 33 can transmit the upper liquid level signal to the controller of the water purifier, and the controller can control the first control valve 32 to be closed, so that more water is prevented from entering the electrolytic cell 31, and the electrolytic water in the electrolytic cell 31 is ensured to be always below the highest liquid level.

Optionally, the electrolytic component 3 further comprises a second detecting element, which is capable of sensing a lower liquid level signal of the electrolytic cell 31, and the first control valve 32 is opened when the lower liquid level signal is triggered.

Wherein, the highest liquid level and the lowest liquid level of the electrolytic cell 31 are written into the controller in advance, and the manufacturer obtains the numerical values of the highest liquid level and the lowest liquid level according to the test and the simulation.

It will be understood that the electrolytic water in the electrolytic cell 31 will also be partially dissolved with hydrogen-containing gas, and in order to make full use of this portion of water, the water purifier further comprises a cleaning line 40, the cleaning line 40 is communicated with the outlet of the electrolytic cell 31, and the cleaning line 40 is connected in parallel with the second branch line 30. The second control valve 5 is arranged on the cleaning pipeline 40, and the second control valve 5 is used for controlling the opening and closing of the cleaning pipeline 40. The user can open second control valve 5 as required to take the electrolytic water in electrolytic cell 31, the electrolytic water can be used for aspects such as decontamination, washing, compare in the running water, the cleaning ability of electrolytic water is stronger, and the cleaning performance is better.

It will be appreciated that the water in the electrolytic cell 31 is located at the lower part of the electrolytic cell 31 and the gas generated by electrolysis is located at the upper part of the electrolytic cell 31, so that the communication position of the cleaning pipe 40 with the electrolytic cell 31 is located at the lower part or bottom of the electrolytic cell 31 and the communication position of the second branch pipe 30 with the electrolytic cell 31 is located at the upper part or top of the electrolytic cell 31.
