Initially, raw water (i.e. tap water or other water which is not filtered) enters from a raw water inlet 121, flows into the filter cartridge through a raw water inlet flow passage 131, a raw water plugging chamber 117, a raw water inlet pipe 209, a raw water internal passage 503, a water inlet hole 502, an upper half chamber and a water outlet hole 504 in sequence, enters the primary filter element from the side surface through a gap between the cartridge body 21 and the primary filter element 901, enters the central cavity after primary filtration, then enters the reverse osmosis filter element 32 from the upper end surface (i.e. the water inlet end surface) of the reverse osmosis filter element 32, after filtration, a part of the filtered pure water enters a pure water production pipe 907, enters the water storage barrel through a pure water through chamber 221, a first check valve chamber 111, a pure water outlet flow passage 132 and a pure water outlet 122, the waste water is discharged into a waste water chamber 222, and a part of the waste water flows into a pure water outlet flow passage 134 through a first waste water outlet 205, a first, the other part of the wastewater is discharged to a sewer through the second wastewater outlet 207, the second wastewater outlet pipe 208, the second plugging cavity 116, the wastewater outlet runner 133 and the wastewater outlet 123. Because the pure water valve and the pure water valve of two taps are all closed, when the pure water in the water storage bucket has stored up, the water pressure in pure water outlet runner 132 can rise, make the initiative valve membrane 311 pressurized drive piston 313 upward movement of control valve 300, and then piston 313 oppresses driven valve membrane 313, make driven valve membrane 312 press and block up inlet opening 502 on the terminal surface of boss 501, with inlet opening 502 and apopore 504 isolated, prevent the inflow of raw water, play the automatic purpose of cutting off the water supply.

Of course, if the reverse osmosis filter element adopts a large-flow reverse osmosis filter element, such as a 1000 gallon large-flow reverse osmosis filter element, the water storage barrel can be omitted, and only the water outlet 122 connected with the water storage barrel needs to be blocked.

When a user selects to use pure water, the pure water valve 23 in the double-outlet faucet 20 is opened (at this time, the pure water valve 24 is closed), along with the outflow of the pure water, the water pressure in the pure water outlet flow channel 132 is reduced, the pressing force on the driving valve membrane 311 is reduced, the piston 313 moves downwards, the driven valve membrane 312 is released, the water inlet hole 502 is opened, the water inlet hole 502 is communicated with the water outlet hole 504 through the upper half cavity, the raw water can be smoothly filtered in the filter cartridge, and the pure water is continuously produced. When the pure water valves of the dual outlet faucets are closed again, the control valve 300 cuts off the raw water from entering and stops the pure water production as the water pressure in the pure water outlet passage 132 rises.

When a user selects to use purified water, the purified water valve 24 in the double-outlet water faucet 20 is opened (at this time, the purified water valve 23 is closed), because the purified water outlet flow passage 134 is communicated with the purified water outlet flow passage 132, the purified water valve 24 in the double-outlet water faucet 20 is opened, the pressure in the purified water outlet flow passage 132 is also reduced, the control valve also opens the water inlet hole 502 as described above to restore to pure water production, and at this time, a part of generated wastewater flows into the purified water outlet flow passage 134 through the first wastewater outlet 205, the first wastewater outlet pipe 206, the third check valve 403 and the third check valve cavity 114, and flows out of the double-outlet water faucet after being mixed with the purified water flowing into the purified water outlet flow passage 134, so that large-flow purified water is formed, and the requirement of non-diet of people. Of course, after the clean water valve 24 of the double faucet 20 is closed again, the control valve 300 cuts off the intake of raw water and stops the water production as the water pressure in the clean water outflow passage 132 increases as described above.

As can be seen from the above detailed description, the present invention has the following advantages:

this cartridge type integral type water purifier has realized can enough going out the pure water, can go out large-traffic water purification again, has promoted the function of this type water purifier, has satisfied user's many-sided water demand to play the effect that reduces waste water discharge, practiced thrift the water resource, have extensive application prospect.

The water route apron seal structure with the control valve sets up in the inside of pedestal, does not have the apron to expose outer problem, even there is leaking also inside the water purifier, can not ooze outside the water purifier to this leak can also pass through the filtration treatment reuse of filter core, prevent to leak and ooze the outside advantage of water purifier, and the water route apron sets up inside the pedestal, does not expose outside, can avoid secondary pollution's problem.
