In this embodiment, as shown in fig. 6, a flow passage is provided in the valve body 2, one end of the flow passage is communicated with the drain chamber 3, the other end is communicated with the concentrate inlet 1, the vertical portion of the second control lever 31 is provided in the flow passage, the two ends of the flow passage are separated by the action of the second sealing ring 17, the second sealing ring 17 is positioned at the position with the minimum inner diameter of the flow passage, the vertical part of the second control rod 31 is of a hollow structure, the second control rod 31 is provided with a water through hole 30 for communicating the fourth flow-resisting channel 27 and the drainage cavity 3, the second control rod 31 is directly sleeved on the second flow-resisting plug 28, so that the second control rod 31 can make relative reciprocating motion along the second choke plug 28 under the action of the second spring 20 and the water pressure inside the purified water inlet 5, in the process that the second control rod 31 slides up and down, impurities on the fourth flow blocking channel 27 can be extruded out, and the fourth flow blocking channel 27 is prevented from being blocked; the top end of the second flow blocking plug 28 is higher than the flow channel of the concentrated water inlet 1, so that in the water making process, concentrated water can only enter a small amount through the fourth flow blocking channel 27, then enters the water discharging cavity 3 through the second flow passing sleeve 26 by the limber hole 30, and then enters the water discharging port 11 by the water discharging cavity 3 to be discharged to the outside, the fourth flow blocking channel 27 is in a long cylindrical shape, in the process of moving downwards by the second control rod 31, the length of the flow channel of the fourth flow blocking channel 27 is adjustable, so that the concentrated water flow can be controlled more accurately, and the first sealing ring 13 sleeved at the lower end of the second adjusting part 29 is used for avoiding concentrated water leakage. When the water for making water stops, the high-pressure switch 109 is closed, the water cut-off valve 103 and the booster pump 105 continue to operate under the action of the delay circuit, so that the pressure of the purified water inlet 5 is increased, the second control rod 31 is extruded to move downwards until the second sealing ring 17 on the vertical part of the second control rod 31 exceeds the position with the minimum inner diameter of the flow channel, at the moment, the two ends of the flow channel are communicated, a large amount of concentrated water enters the drainage cavity 3 through the flow channel and is discharged through the drainage port 11, and the flushing of the large-flux reverse osmosis filter group 106 is realized.

The utility model discloses a theory of operation:

in the process of water production of the pure water machine, the high-pressure switch 109, the water cut-off valve 103 and the booster pump 105 are started, raw water enters from a raw water pipe, partial large-volume impurities are filtered out in advance through the first filter group 102 and the second filter group 104, the raw water subjected to primary filtration enters the large-flux reverse osmosis filter group 106 after being pressurized through the booster pump 105, the increased pressure is matched with the working pressure of the large-flux reverse osmosis filter group 106 to ensure that the pure water can be normally produced, the pure water discharged from the large-flux reverse osmosis filter group flows to the pure water faucet 110 through the high-pressure switch 109, the pure water faucet 110 is opened, the pure water can flow out, at the moment, the pressure at the purified water inlet 5 connected with the purified water pipe 107 is small, and the flow blocking component cannot be extruded downwards to move, so that the flow blocking component blocks the amount of concentrated water entering the drainage cavity 3 from the concentrated water inlet 1, and the concentrated water can only slowly enter the drainage cavity 3 through the flow blocking channel in a small amount and is discharged to the outside of the valve body 2 through the communicated water outlet 11.

When the water purifier stops producing water, the high-voltage switch 109 is closed, the delay circuit is started, at the moment, the booster pump 105 and the water cut-off valve 103 continue to operate, so that the water pressure at the clean water inlet 5 is increased, the water pressure acts on the first diaphragm 4 downwards, the periphery of the first diaphragm 4 is pressed and sealed on the valve body 2 through the valve cover 6, so that the purified water does not enter the drainage chamber 3 from the purified water inlet 5, the pressure value in the purified water pipe 107 is ensured, the first diaphragm 4 acts downward on the flow blocking member under the action of the water pressure, the flow-blocking component is moved downwards until the flow-blocking component is separated from the flow-blocking channel, so that the flow-blocking channel is changed into a high-flow channel, a large amount of concentrated water enters the drainage cavity 3 through the unimpeded flow blocking channel and then flows into the drainage outlet 11, thereby driving the water in the large-flux reverse osmosis filter group 106 to be discharged from the concentrated water pipe at large flux, and achieving the effect of flushing the large-flux reverse osmosis filter group 106.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and the technical essence of the present invention is that within the spirit and principle of the present invention, any simple modification, equivalent replacement, and improvement made to the above embodiments are all within the protection scope of the technical solution of the present invention.
