The primary filter element 901 is composed of PP cotton and a carbon rod, wherein the PP cotton can filter out silt, oxidation substances and suspended solids in water, and the carbon rod can remove chlorine and peculiar smell in water. The reverse osmosis filter element 32 can further filter out bacteria, viruses and heavy metals in the water, and finally pure water is obtained.

The double-water-outlet barrel-type integrated water purifier of the invention has the following working modes:

the raw water inlet 121 is connected to a tap water pipe, and referring to fig. 17, the two pure water outlets 122 of the pure water outlet channel 132 are connected to the pure water pipes 81 of the water storage tank and the double water faucet 80, respectively, the waste water outlet 123 is connected to a waste water pipe, and the pure water outlet 124 is connected to the pure water pipe 82 of the double water faucet 80. A waste water proportion regulating valve is arranged in the waste water pipe.

In the case where both the pure water valve 83 and the pure water valve 84 of the double outlet water 80 are closed. Initially, raw water (i.e., tap water or other unfiltered water) enters the raw water inlet channel 131, the raw water plugging chamber 117 and the raw water plugging pipe 209 from the raw water inlet 121. Raw water of the raw water insertion pipe 209 is divided into two paths in the waterway cover plate, one path can flow into the filter cartridge through the first raw water plate inner channel 503, the first water inlet 502, the first upper half cavity, the first water outlet 504 and the raw water inlet cavity 230, and the other path can flow into the filter cartridge through the second raw water plate inner channel 503 ', the second water inlet 502 ', the second upper half cavity, the second water outlet 504 ' and the raw water inlet cavity 230. The water flowing into the filter cartridge flows into the purified water outlet flow channel after being filtered by the filter element assembly, when the pressure in the purified water outlet flow channel is increased, the second control valve 300' is driven to cut off the second water control flow channel section, the raw water is automatically closed to enter the cartridge from the second water control flow channel section, and the manufacture of purified water is automatically stopped; when the pure water in the water storage barrel is full, the water pressure in the pure water outlet channel 132 is increased, the first control valve 300 is driven to cut off the first water control channel section, the raw water is automatically closed to enter the barrel from the first water control channel section, and the production of the pure water is automatically stopped.

When pure water is needed, the pure water valve 83 in the double outlet water 80 is opened (at this time, the pure water valve 84 is closed). Since the clean water valve 84 is closed, the water pressure in the clean water outlet flow channel 134 is still relatively high, and the second control valve 300' is kept driven to block the second water control flow channel section. And because the pure water valve 84 is opened, along with the consumption of pure water in the water storage barrel, the water pressure in the pure water outlet flow passage 132 is reduced, the first control valve 300 is released, so that the first water control flow passage section is smooth, and raw water can enter the barrel through the water control flow passage section through the first water inlet hole 502. Raw water entering the cartridge 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, enters the reverse osmosis filter element 32 from the upper end surface of the reverse osmosis filter element 32, namely the water inlet end surface, and after filtration, a part of the raw water becomes pure water and enters the pure water production pipe 907, and flows into the water storage barrel through the pure water through cavity 221, the pure water check valve cavity 111, the pure water outlet flow passage 132 and the pure water outlet 122 to obtain pure water. The waste water is discharged into the waste water cavity 222, and because the water pressure in the purified water outlet channel 134 is high, the waste water cannot be discharged from the second outlet 205, and can only be discharged to a sewer through the second outlet 207, the waste water plug pipe 208, the waste water plug cavity 116, the waste water outlet channel 133 and the waste water outlet 123. When the pure water valve 83 is closed, the water pressure in the pure water outlet channel 132 rises with the filling of pure water in the water storage barrel, and then the first control valve 300 is driven to cut off the first water control channel section, so that the raw water is prevented from entering, and the automatic water control is realized.

When water purification is required, the purified water valve 84 in the double outlet water 80 is opened (at this time, the purified water valve 83 is closed), and since the purified water valve 83 is closed, the water pressure in the purified water outlet flow passage 132 is high, and the first control valve 300 is driven to block the first water control flow passage section.

And because the purified water valve 84 is opened, the water pressure in the purified water outlet flow passage 134 is low, the second control valve 300 'is released, so that the second water control flow passage section is smooth, and raw water can enter the cylinder through the second water control flow passage section through the second water inlet hole 502'. The raw water entering the barrel enters the primary filter element from the side surface through the gap between the barrel body 21 and the primary filter element 901, enters the central cavity after primary filtration, and because the water pressure in the pure water outlet flow passage is high and the water pressure in the purified water outlet flow passage 134 is low at this time, the water entering the central cavity cannot flow into the water production pipe through the permeation of the reverse osmosis membrane, but directly flows to the waste water end through the surface of the reverse osmosis membrane, is discharged to the purified water outlet flow passage 134 from the first water discharge port 205, and finally directly obtains purified water from the double water discharge taps. Since the waste water proportion adjusting valve is provided in the waste water pipe 82, even if a part of the waste water is discharged into the waste water pipe from the second discharge port, the amount of waste water is extremely small because the waste water proportion adjusting valve has a large resistance to water. When the purified water valve 84 is closed, the water pressure in the purified water outlet channel 134 increases, and the second control valve 300' is driven to block the second water control channel section, so as to prevent the raw water from entering and realize automatic water control.

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

the cylinder type integrated water purifier realizes the independent manufacture of pure water and purified water, the purified water is manufactured without mixing waste water and the pure water, and the purified water can not be discharged from the water storage barrel. The water purification is directly obtained from the surface outflow of reverse osmosis membrane after filtering through the primary filter element, consequently, the flow ratio is bigger, can play the washing effect to reverse osmosis membrane on the one hand, and on the other hand also does not have through reverse osmosis infiltration, reduces the loss to reverse osmosis membrane, is favorable to prolonging reverse osmosis membrane's life, even there is the water purification to discharge from the waste water runner in the preparation water purification process, owing to there is waste water proportion regulating valve's existence, also is the water purification of minute quantity and discharges, is favorable to the water economy resource.
