In the waterway structure of the water purifier provided by the present application, by providing the water storage tank 3 having the raw water chamber 31 and the purified water chamber 32 with variable volumes, and connecting the raw water chamber 31 with the raw water inlet pipeline 4 and the raw water outlet pipeline 5, and connecting the purified water chamber 32 with the purified water inlet pipeline 6 and the purified water outlet pipeline 7, when the purified water outlet pipeline 7 is discharging water (the purified water outlet pipeline 7 is used for connecting with a water port which can be a water tap, etc., the water port is opened, and the purified water outlet pipeline 7 is discharging water), the raw water inlet pipeline 4 always feeds water into the raw water chamber 31, because the raw water inlet pipeline 4 is generally used for connecting with a tap water pipeline, and the outlet pressure of the tap water pipeline is greater than the outlet pressure of the filtering device 1, therefore, the pressure in the raw water chamber 31 is greater than the pressure in the purified water chamber 32, and both the raw water chamber 31 and the purified water chamber 32 maintain a relatively constant pressure state, after the water port is closed to cut off the purified water outlet pipeline 7, the raw water in the raw water cavity 31 continues to produce purified water through the filter device 1 in a certain time under the action of pressure to enter the purified water cavity 32, the pressure in the raw water cavity 31 and the purified water cavity 32 changes together, namely, the water pressure in the raw water cavity 31 is gradually reduced, and the water pressure in the purified water cavity 32 is continuously increased, so that the control valve can be triggered when the pressure in the purified water cavity 32 is continuously increased to a certain value, and the raw water inlet pipeline 4 is cut off by the control valve.

It can be seen that the control valve is triggered by the pressure change in the raw water cavity 31 and/or the purified water cavity 32, the control valve can be of a type without an external power supply such as a four-sided valve 2, and further does not need to control the cutting of the water channel of the water purifier by electric control, the cutting of the water channel of the water purifier can be realized only by disconnecting the water port communicated with the purified water outlet pipeline 7, the operation is very convenient, and particularly, the water channel structure can be applied to electroless water purification machines and reverse osmosis water purifiers.

In addition, cut water purification outlet pipe way 7 after, the water of a part in the former water cavity 31 continues to filter through filter equipment 1 and makes certain pressure in the water purification cavity 32 for the water purification storage makes in the water purification cavity 32, after opening the water purification outlet pipe once more, former water inlet pipe way 4 continues to supply water to the former water cavity, the water that gets into in former water cavity 31 extrudees the water purification in the water purification cavity 32 away, can effectively increase the flow in the water purification outlet pipe way 7, guarantee that the water port goes out fast, promote user experience and feel.

As a preferred embodiment of the present application, as shown in fig. 1, the raw water inlet pipeline 4 includes a first branch 41 and a second branch 42, the first branch 41 is communicated with the raw water chamber 31, and the second branch 42 is communicated with the inlet end of the filtering device 1; the purified water inlet pipeline 6 comprises a third branch 61 and a fourth branch 62, the third branch 61 is communicated with the purified water cavity 32, and the fourth branch 62 is communicated with the purified water outlet pipeline 7.

Through making the first branch 41 with former water cavity 31 intercommunication, second branch 42 intercommunication the entrance point of filter equipment 1 just the third branch 61 with the water purification cavity 32 intercommunication, fourth branch 62 with water purification outlet pipe way 7 intercommunication forms first branch 41 and former water outlet pipe way 5 and goes out water to third branch 61 and fourth branch 62 to filter equipment 1's entrance point influent water and filter equipment 1's exit end together, on the one hand, helps promoting former water inflow and pressure of intaking, and then improves water purification water yield and play water pressure, promotes the large flux and goes out water, on the other hand, fourth branch 62 and water purification outlet pipe way 7 intercommunication, when the waterway structure of this application is applied to the reverse osmosis water purifier, after stopping making water, the TDS value of the water storage in water purification cavity 32 is very low and can not increase automatically, when opening the water port again and making water purification outlet pipe way 7 go out water, the higher water purification of the direct TDS that flows out from filter equipment 1 in fourth branch 62 can be diluted after the water storage in water purification chamber 32 gets into water purification outlet pipe 7, and then reduces the TDS of first glass of water, makes first glass of water reach the standard that can directly drink.

As a preferred example of the present embodiment, as shown in fig. 1, the water purifier waterway structure includes two control valves, one of which is disposed in the first branch 41 to communicate with or block the first branch 41, and the other of which is disposed in the second branch 42 to communicate with or block the second branch 42.

Because the first branch 41 is directly communicated with the raw water chamber 31, after the purified water outlet pipeline 7 is cut off, the changes of the raw water chamber 31 and the purified water chamber 32 make the water pressures of the first branch 41 and the second branch 42 have a certain difference, so that two control valves are arranged to respectively control the on-off of the first branch 41 and the second branch 42, and the accurate control of the on-off of each branch can be ensured.

Moreover, the difference of the water pressure of the raw water cavity 31 and the purified water cavity 32 can selectively make the triggering time points of the two control valves different, when one control valve controls the branch where the other control valve is located to be cut off, the branch where the other control valve is located can continue to produce water through the filtering device 1, the water storage amount in the purified water cavity 32 and the water pressure of the stored water are increased, and further the water pressure and the water amount when purified water is discharged again from the purified water outlet pipeline 7 are increased.

As a preferable example of the present embodiment, as shown in fig. 1 and 3, the control valve is a four-sided valve 2, the four-sided valve 2 includes a valve body 21 provided with a high-pressure water inlet passage 211 and a low-pressure water outlet passage 212, and a sealing member 22 provided in the valve body 21, specifically, the sealing member 22 includes an elastic body 221 located on one side of the low-pressure water outlet passage 212 and a piston 222 located on one side of the high-pressure water inlet passage 211, and the elastic body 221 deforms when the liquid pressure in the low-pressure water outlet passage 212 increases and presses the piston 222 into the high-pressure water inlet passage 211 to block the high-pressure water inlet passage 211.

The four-sided valve 2 does not need circuit control, the water path can be switched on and off only according to water pressure changes, and the water-break sensitivity of the four-sided valve 2 is high and the sealing effect is good through the cooperation of the elastic body 221 and the piston 222.

Further, the first branch 41 and the third branch 61 are connected to the high-pressure water inlet passage and the low-pressure water outlet passage of one of the four-sided valves 2, respectively, and the downstream sections of the second branch 42 and the clean water outlet pipeline 7, which are connected to the fourth branch 62, are connected to the high-pressure water inlet passage and the low-pressure water outlet passage of the other four-sided valve 2, respectively. For convenience of explanation and understanding, the four-way valve 2 connected to the first branch 41 is referred to as a first four-way valve 23, and the four-way valve 2 connected to the second branch 42 is referred to as a second four-way valve 24.

As shown in fig. 1, when the water port is opened to allow the purified water outlet pipeline 7 to discharge water, the high-pressure water inlet passage and the low-pressure water outlet passage of the first four-sided valve 23 and the second four-sided valve 24 are both in an open state, and the water purifier realizes the water inlet, the water preparation and the water discharge. As shown in fig. 2, at the moment when the water port is closed to cut off the purified water outlet pipe 7, the pressure in the purified water chamber 32 is minimum and the purified water in the purified water chamber 32 cannot be discharged to the purified water outlet pipe 7, the second four-sided valve 24 can cut off the second branch 42 connected to the high-pressure water inlet passage according to the minimum pressure in the purified water chamber 32 and under the pressure in the low-pressure water outlet passage connected to the purified water outlet pipe 7, after the second branch 42 is cut off, the raw water inlet pipe 4 continues to feed water through the first branch 41, because the purified water in the purified water chamber 32 cannot be discharged, the pressure increases gradually with the increase of the purified water, when the pressure in the purified water chamber 32 reaches the maximum, the first four-sided valve 23 can cut off the first branch 41 connected to the high-pressure water inlet passage according to the maximum pressure in the purified water chamber 32 and under the pressure in the low-pressure water outlet passage connected to the third branch 61, at this time, the first branch 41 and the second branch 42 are both in a cut-off state, the water purifier waterway structure stops feeding raw water, then the raw water in the raw water cavity 31 continues to be filtered and then enters the water purification cavity 32, and finally water production is stopped when the pressures in the raw water cavity 31 and the water purification cavity 32 reach a balance.
