The check valve 1 functions to prevent air or water from flowing back to the pressurizing pump 410 or the water inlet control valve 420 when the tap live water is turned off, thereby enabling to maintain the pressure in the air-water mixing tank 310.

Further, referring to fig. 3, in order to increase the water inflow of the water purification branch 400, in an embodiment of the present application, the water circuit board further includes a parallel branch 500, and a parallel control valve 510 is disposed on the parallel branch 500; the water inlet waterway 100 is provided with a pre-filter, the water inlet of the parallel branch 500 is communicated between the pre-filter and the pressure reducing valve 120, and the water outlet of the parallel branch 500 is communicated with the water inlet of the water purifying branch 400.

Specifically, the pure water port of the reverse osmosis filter 430 is sequentially communicated with a second one-way valve, a post-filter and a second water tap, and the second water tap is used for allowing drinking water to flow out. When the pure water bypass 400 is operated, the parallel control valve 510 and the water inlet control valve 420 are opened, so that the raw water flows toward the booster pump 410 through the parallel control valve 510 and flows into the reverse osmosis filter 430 through the booster pump 410, thereby enabling to increase the pure water flow rate. The second check valve functions to prevent the purified water from flowing back to the reverse osmosis filter 430, and maintains the pressure in the pipeline when the second tap is turned off.

Further, referring to fig. 3, in order to prevent the water stored in the water purifying branch 400 from being polluted, in an embodiment of the present application, the water circuit board further includes a backflow branch 600, a water inlet of the backflow branch 600 is communicated with the pure water end of the reverse osmosis filter 430, and a water outlet of the backflow branch 600 is communicated with a water inlet of the water purifying branch 400. So, when second tap closed for a long time, the water of depositing in the water purification branch road 400 can flow back to water purification branch road 400 through backward flow branch road 600 to purify once more through the reverse osmosis filter core, consequently can guarantee the cleanliness factor of drinking water.

Specifically, a water inlet of the backflow branch 600 is communicated with a pure water inlet of the reverse osmosis filter 430, a water outlet of the backflow branch 600 is communicated with a water inlet of the booster pump 410, a backflow control valve is arranged on the backflow branch 600, a third one-way valve is arranged between the backflow control valve and the reverse osmosis filter 430, and the third one-way valve is in one-way conduction from one side of the pure water inlet of the reverse osmosis filter 430 to one side of the backflow control valve.

Referring to fig. 3, the water path system of the water path plate will be described in detail. After entering from the raw water inlet, the raw water (tap water) is filtered by a pre-filter 130(PAC composite filter element), and then divided into two paths, one path passes through a pressure reducing valve 120 with a pressure reducing parameter of 0.2MPa, and then passes through an interceptor 110, and the other path passes through a parallel control valve 510 and then converges. The converged water enters the booster pump 410, and after the water is subjected to the boosting action of the booster pump 410, the water is divided into two paths again, one path of the water passes through the first check valve 320 and the air-water mixing tank 310 and then is discharged from the first faucet (live water), and the other path of the water passes through the water inlet control valve 420 and then enters the reverse osmosis filter 430. The reverse osmosis filter 430 separates the water into concentrated water and purified water, and the concentrated water passes through the flush control valve and is discharged through the drain port. The purified water from the reverse osmosis filter 430 is divided into two paths, wherein one path of the purified water passes through the second one-way valve and the post-filter 440 (carbon rod filter element) and then is discharged from the outlet of the second faucet (drinking water). The air inlet can suck air, the air is converged with the other path of purified water from the reverse osmosis filter 430 after passing through the air inlet control valve and the fourth one-way valve, and then flows back through the backflow control valve, the interceptor 110 and the parallel control valve 510, and then enters the booster pump 410. The second high-pressure switch is connected to the pipeline between the post-filter 440 and the drinking water outlet, and the first high-pressure switch is connected to the pipeline between the gas-water mixing tank 310 and the domestic water outlet.

At the same time, the parallel control valve 510 and the water inlet control valve 420 on the water circuit will be closed and the water inlet control valve will be opened. At this time, the water can reach the pressurizing pump 410 only through the pre-filter 130, the pressure reducing valve 120 and the interceptor 110. Due to the interception of the interceptor 110 and the pumping action of the booster pump 410, a certain negative pressure is generated in the front-end water path of the booster pump 410, and gas (air) enters the water path through the air inlet control valve and joins the water flow passing through the interceptor 110 after passing through the check valve. The pressure pump 410 pressurizes the merged gas and water together and then enters the gas-water mixing tank 310, and the gas and the water are fully mixed and dissolved in the gas-water mixing tank 310 under the action of high pressure (0.3-0.5 MPa). And finally, releasing the pressure at the water outlet of the first water faucet, wherein the gas is not dissolved in the water any more and forms a plurality of tiny bubbles in the water, so that the micro-bubble water is discharged.

When the user turns on the second faucet and turns off the first faucet, the second high-pressure switch installed in the water path of the post-filter 440 detects the pressure reduction of the water path, and the control system activates the booster pump 410 to continuously boost the water. At the same time, the parallel control valve 510 and the water inlet control valve 420 on the water circuit will be opened and the water inlet control valve will be closed. At this point, the water may pass through the pre-filter 130 and then through the parallel control valve 510 to the booster pump 410. The water pressurized by the pressurizing pump 410 enters the reverse osmosis filter 430 after passing through the water inlet control valve 420, and the reverse osmosis filter 430 separates purified water and concentrated water. The concentrated water passes through the flush control valve and is discharged to the sewage through the drain port, and the purified water passes through the post-filter 440 and flows out of the faucet.
