Referring to FIG. 4 and FIG. 7 , the water storage tank A of the present invention is matched with a reverse osmosis filter core 5, a front filter core 6, a filter core group 61, an automatic water shutoff valve 62, and the like. The filter core 7, the four-way pipe 73, a drain pipe 82 and some pipes are assembled according to the new reverse osmosis water purifier system B, and the water inlet 51 of the reverse osmosis filter 5 is connected to the front type. The filter core 6 , the water outlet 52 of the reverse osmosis filter 5 is connected to the purified water inlet and outlet passage c of the water storage tank A and the rear filter core 7 by the four-way pipe 73, and the wastewater of the reverse osmosis filter core 5 The drain port 53 is connected to the waste water inflow passage a of the water storage tank A.

The reverse osmosis water purifier system B uses a low and medium pressure mold for a water source with a specific water pressure, so the pump is not used to drive the flow of the raw water, so when the raw water flows to the reverse osmosis filter 5, it usually occurs. A trace amount of pure water and waste water, and the purified water and the waste water are respectively flown into the passage hole c through the passage channel c and the waste water inflow passage a into the through hole 111b and the through hole 111 of the water storage tank A, and the pure water finally comes from The combined passage 33 flows into the soft bag body 31 to form a purified water region, and the waste water flows into the waste water region formed by the accommodating space 11 outside the flexible bag body 31. The water pressure P2 of the purified water area in the water storage tank A is to be maintained. As shown in FIG. 8, the second water flow actuating portion 233 is moved to the left by the water pressure P2 during the water making to turn on the waste water discharge passage b and the through hole 111a. The waste water enters the second pipe 215 and the first pipe 214 in the water flow differential pressure multi-directional control valve body 2 through the through hole 111a, and the waste water discharge passage b is discharged to the drain pipe 82, if the water pressure P2 When the pressure is reduced to be lower than the elastic force P3, the water flow pressure difference switching lever 23 is moved to the right to close the passage between the waste water discharge passage b and the through hole 111a.

Referring to FIG. 4 and FIG. 9, after the soft pure water tank 3 of the water storage tank A is filled with the pure water produced by the reverse osmosis water purifier system B, a predetermined water pressure P2 is accumulated, because The spatial squeeze effect of the soft pure water liner 3.

Referring to FIG. 4 and FIG. 10, when the person to be opened opens the outlet faucet 72, the purified water in the water storage tank A enters the large amount of wastewater due to the specific water pressure P2 in the soft pure water tank 3. In the waste water area of the water storage tank A, water is discharged due to the space squeezing effect of the waste water area, and the purified water is caused to flow to the rear type filter core group 71, and then flows to the water discharge tap 72 to supply pure water. At the same time, the water pressure P2 in the soft pure water tank 3 is rapidly lowered to start the reverse osmosis water purifier B to continue the water production. At this time, since the reverse osmosis water purifier system B continues to produce pure water, the wastewater produced by the reverse osmosis water purifier system B continues to flow into the water storage tank A through the wastewater inflow passage a and the through hole 111 and the through hole 111a. The water pressure of the wastewater injected into the water storage tank A is also continuously injected, so that the space squeeze effect of the wastewater area continues to squeeze the water of the soft pure water tank 3 until the water outlet tap 72 is closed to stop the water discharge.

The water tank A bursts due to the water pressure being too high.

Referring to FIG. 11, there is a reverse osmosis water purifier system B1 that matches the water storage tank A. The difference between the reverse osmosis water purifier system B1 and the aforementioned reverse osmosis water purifier system B is only The reverse osmosis water purifier system B1 uses the automatic water shutoff valve 63 and the three-way pipe 74, and is also applied to a water source with a specific water pressure, and does not use a pump to drive the raw water flow, so that it can also be achieved. The kinetic energy of the wastewater produced by the wastewater drives the function of the water supply to the water storage tank A.

Referring to FIG. 12, there is a reverse osmosis water purifier system B2 that matches the water storage tank A. The difference between the reverse osmosis water purifier system B2 and the aforementioned reverse osmosis water purifier system B1 is only The reverse osmosis water purifier system B2 increases the use of the pressure switch 64 or the solenoid valve, the pump 65, and electrically connects the pressure switch 64 or the solenoid valve and the pump 65 to the electronic control module 81 and the power source 8. The reverse osmosis water purifier system B2 uses a pump 65 to drive the raw water to flow, and generates a preset water pressure, and the water pressure raw water has to open a rubber in the automatic water shutoff valve 63 to flow to the reverse osmosis. The filter core 5 is used to produce a trace amount of purified water and waste water, and the purified water and waste water are respectively flown into the water storage tank A through the purified water inlet and outlet passage c and the wastewater inflow passage a.

After the water storage tank A is full, the pure water has a back pressure P2 to a rubber 631 in the automatic water shutoff valve 63, and the rubber 631 blocks the raw water passage, interrupting the pump 65 to discharge the raw water to the water. The reverse osmosis filter 5 accumulates a preset pressure. When the pressure switch 64 detects the preset pressure, the electronic control module 81 turns off the solenoid valve and the pump 65.

When the water storage tank A is supplied with water, the pressure is released from the automatic water shutoff valve 63, and the raw water can be flushed to the rubber 631 in the automatic water shutoff valve 63 to flow to the reverse osmosis filter 5, and the pressure switch 64 detects no When the pressure is applied, the electronic control module 81 activates the pump 65 to allow the raw water to continuously open a rubber 631 in the automatic water shutoff valve 63 and flow to the reverse osmosis filter 5 to produce pure water. And the waste water, and the pure water and waste water are accumulated in the water storage tank, and the circulation is reversed, so that the reverse osmosis water purifier system B2 can also drive the water supply and water supply of the water storage tank A by the kinetic energy of the waste water produced by the reverse osmosis water purifier system B2.
