It is understood that, in other embodiments, the waterway system of the present application is not limited to be used in a water purifier, but may also be used in other drinking water devices that may use the waterway system, and is not limited herein.
A preferred embodiment of the waterway system is described below with reference to fig. 1.
A water purifier comprises a housing (not shown), a water path system 10, a control panel (not shown) and a display panel (not shown) which are arranged in the housing. The control panel is in communication connection with the waterway system 10 and is used for controlling the operation of the waterway system 10; the display panel is also in communication connection with the waterway system 10 and is used for displaying the filtered water quality value.
As shown in fig. 1, a waterway system 10 of a water purifier includes a water inlet 110, an ultrafiltration membrane filter element 120, a booster pump 130, a reverse osmosis membrane filter element 140 and a water outlet 150 which are connected in series by pipes in sequence (all the subsequent connections are pipe connections). The ultrafiltration membrane filter element 120 is used for filtering to generate ultrafiltration water; the reverse osmosis membrane filter element 140 is used for filtering to generate reverse osmosis purified water; as described in the background, reverse osmosis is achieved on the premise that it is driven by pressure based on the characteristics of the reverse osmosis membrane itself, and the booster pump 130 is used to boost the pressure of water to provide reverse osmosis pressure.
Wherein, the booster pump 130 and the reverse osmosis membrane filter element 140 form a series waterway; the water path in which the water inlet 110, the ultrafiltration membrane filter element 120, the booster pump 130 and the reverse osmosis membrane filter element 140 are connected forms a pure water path 100, and the serial water path formed by the booster pump 130 and the reverse osmosis membrane filter element 140 is a part of the pure water path 100. The waterway system 10 further comprises an adjusting valve 210 for adjusting the ultrafiltration water flow, the adjusting valve 210 is connected in parallel with a serial waterway formed by the booster pump 130 and the reverse osmosis membrane filter element 140, the adjusting valve 210 is connected in series with the ultrafiltration membrane filter element 120, the serial waterway formed by the reverse osmosis membrane filter element 140 and the ultrafiltration membrane filter element 120 and the adjusting valve 210 form a parallel structure 101, and the water outlet 150 is connected with the water outlet end of the parallel structure 101. The water inlet 110, the ultrafiltration membrane filter element 120 and the regulating valve 210 form an ultrafiltration water waterway 200, and the pure water waterway 100 and the ultrafiltration water waterway 200 are converged together and connected to the water outlet 150.
Thus, the outlet water of the ultrafiltration membrane filter element 120 is divided into two paths, one path of the inlet water serving as the reverse osmosis membrane filter element 140 passes through the booster pump 130 and the reverse osmosis membrane filter element 140 to obtain reverse osmosis purified water, and the other path of the outlet water serving as the ultrafiltration membrane filter element 120 passes through the regulating valve 210 for regulation and finally joins into mixed water of two water qualities. Because the first-stage filter element is the ultrafiltration membrane filter element 120, the inlet water of the reverse osmosis membrane filter element 140 is ultrafiltration water, the filtration pore diameter of the ultrafiltration membrane is smaller, and the inlet water of the reverse osmosis membrane filter element 140 has higher filtration precision.

Specifically, the first water inlet valve 160 serves as a main valve at the upstream of the ultrafiltration membrane filter element 120, and can control the opening and closing of water in the entire waterway system 10, and when the first water inlet valve 160 is opened, raw water can be introduced into the ultrafiltration membrane filter element 120 for the first-stage filtration; when the first water inlet valve 160 is closed, the raw water cannot be introduced into the ultrafiltration membrane filter element 120, thereby stopping the water production; the second inlet valve 170 is used to control the inlet of the pure water circuit 100, and the third inlet valve 220 is used to control the inlet of the ultrafiltration circuit.
When the second water inlet valve 170 and the third water inlet valve 220 are simultaneously opened, the water filtered by the ultrafiltration membrane filter element 120 can be divided into two paths which respectively pass through the water path of the reverse osmosis membrane filter element 140 and the water path of the regulating valve 210 and then are converged together to prepare two kinds of mixed water with different water qualities, namely ultrafiltration water and reverse osmosis pure water. When the second water inlet valve 170 is separately opened, the water filtered by the ultrafiltration membrane cartridge 120 is filtered only by the reverse osmosis membrane cartridge 140 to obtain reverse osmosis purified water. When the third water inlet valve 220 is separately opened, the water filtered by the ultrafiltration membrane filter element 120 can only pass through the regulating valve 210 to obtain ultrafiltration water.
In addition, set up first check valve 230 between governing valve 210 and milipore filter core 120 for the water after the filtration of milipore filter core 120 can only one-way flow adjust to governing valve 210, and can not flow back, has guaranteed effectively that it can supply the regulation to have sufficient ultrafiltration flux, and the ultrafiltration flux is big more, and adjustable TDS value is big more.

Because ultrafiltration membrane filter core 120 has been used for a long time, have some attachments after filtering and adhere to the internal surface of milipore filter in ultrafiltration membrane filter core 120, thereby cause the filter core easily to block up, lead to the flux of ultrafiltration membrane filter core 120 to diminish, and then influence the regulation effect of ultrafiltration water, can just wash ultrafiltration membrane filter core 120 this moment in order to get rid of the attachments attached to milipore filter internal surface, only need open flushometer 310, and set up certain reasonable time, make the raw water directly wash the internal surface of milipore filter can, the rivers after washing go out and wash mouth 320.
With continued reference to fig. 1, in some embodiments, a buffer tank 121 is connected between the parallel arrangement 101 and the ultrafiltration membrane cartridge 120 (i.e., downstream of the ultrafiltration membrane cartridge 120). The buffer tank 121 is arranged to protect the ultrafiltration membrane of the ultrafiltration membrane filter element 120, and due to the existence of the buffer tank 121, when the water pump pumps raw water, the membrane back pressure (the membrane front pressure is the water pressure of tap water) of the ultrafiltration membrane cannot form instantaneous zero pressure or negative pressure, so that fatal damage to the structure of the ultrafiltration membrane and membrane wires of the ultrafiltration membrane caused by the instantaneous zero pressure or negative pressure is avoided.
