In order to make the technical solution, the purpose and the advantages of the present invention more apparent, the present invention will be further explained with reference to the accompanying drawings and embodiments.
As shown in fig. 1 to 2, the water purification system of the present invention includes a raw water input end 1, a wastewater output end 7, and a pure water output end 8, and further includes a three-way ball valve 11, a pre-filter element assembly 2, a first control valve 31, a booster pump 32, a reverse osmosis filter element assembly 4, a second control valve 50, a first check valve 51, a second check valve 53, a high-pressure switch 52, and a wastewater control valve 71, wherein the reverse osmosis filter element assembly 4 is provided with a pure water inlet 401, a wastewater outlet 402, and a pure water outlet 403.
Water flows along the raw water input end 1, the three-way ball valve 11, the preposed filter element assembly 2, the first control valve 31 and the booster pump 32 to the purified water inlet 401 to form a purified water inlet flow passage;
the water flows from the pure water outlet 403, the first output end 501 of the second control valve 50, the first one-way valve 51, the high-voltage switch 52, the post-filter element assembly 6 to the pure water output end 8 to form a pure water outlet flow channel; the first check valve 51 unidirectionally directs the water flow from the first output 501 of the second control valve 50 to the high pressure switch 52 position setting; the post-filter element assembly 6 is optionally disposable based on practical application needs.
The water flows along the waste water outlet 402, the waste water control valve 71 to the waste water output end 7 to form a waste water outlet flow channel;
the water flows along the pure water outlet 403, the second output end 502 of the second control valve 50, the second check valve 53 to the wastewater output end 7, so that a pure water drainage flow passage is formed; the second check valve 53 directs the flow of water in one direction from the second output 502 of the second control valve 50 to the waste water output 7 position.
The first check valve 51 and the second check valve 53 are both non-pressure check valves.
A pure water reverse-flow prevention structure for preventing pure water from flowing reversely is arranged in the reverse osmosis filter element assembly 4, specifically, the reverse osmosis filter element assembly 4 comprises a central pipe 41 and an RO membrane assembly 42 arranged around the central pipe 41, and a pure water outlet end 411 of the central pipe 41 is communicated with the pure water outlet 403; the pure water check structure comprises a pure water check valve 9 arranged between the pure water outlet 411 and the pure water outlet 403, and the pure water check valve 9 is used for guiding water flow in a check mode from the pure water outlet 411 to the pure water outlet 403.
Specifically, the waterway application principle of the water purification system is as follows:
under the normal water production state, an external tap water source is input from the raw water input end 1, the first control valve 31 is in an open state, and under the driving of the booster pump 32, primary filtration is carried out from the three-way ball valve 11 to the front filter element assembly 2 to obtain purified water; the obtained purified water passes through the first control valve 31 and the booster pump 32 to reach the position of the purified water inlet 401, and is input to the reverse osmosis filter element assembly 4 through the purified water inlet flow passage.
The input purified water is filtered by the reverse osmosis filter element component 4 to generate pure water and wastewater; the second output 502 of the second control valve 50 is normally closed; the pure water flow is output to the pure water output end 8 along the pure water outlet flow passage, and the pure water output end 8 is connected with a water using component 81 such as a water tap and the like for leading out the pure water.
The waste water control valve 71 is in an open state, and a flow of waste water is output along the waste water outlet flow path to the waste water output 7, and the waste water output 7 is similarly connected with a corresponding water outlet assembly 72 for collection application of waste water extraction.
After the water purification system stops working, the TDS value of the pure water side of the RO membrane module 42 will increase with time until the solute concentrations of the raw water side and the pure water side reach equilibrium; taking water directly from the water using assembly 81 in this way will result in a higher TDS value of the first cup of water being taken.
Therefore, when the user turns on the water using assembly 81 at the pure water output end 8 again, the water purifying system is started by the high-voltage switch 52 controlled by the program, the first control valve 31 is opened, and the external tap water source is input into the reverse osmosis filter element assembly 4 again through the pure water inlet channel under the driving of the booster pump 32; at this time, the second output terminal 502 of the second control valve 50 is opened and the first output terminal 501 is closed, and the generated pure water with a high TDS value is led out to the position of the wastewater output terminal 7 through the pure water drainage channel, so that the generated pure water is led out as wastewater from the corresponding water outlet assembly 72 along with the wastewater.
Subsequently, after a preset time, the second output end 502 of the second control valve 50 is closed and the first output end 501 thereof is opened, the pure water drainage flow channel is closed, the water purification system enters a normal water production state, and the produced pure water is continuously guided to the pure water output end 8 for output.
This water purification system is through selecting to discharge the higher first cup of water of TDS value priority to directly solve the problem that the user first cup of water experienced the sense.
Accordingly, when pure water is retained in the water path between the pure water opening and the second control valve 50 due to the deactivation of the external water module 81, the retained pure water will flow back to the RO membrane module 42 along with the central tube 41 through the pure water outlet 403, resulting in the waste of pure water; the pure water check valve 9 is arranged, so that the stable flow direction of the pure water flow is ensured, the counter flow of the pure water is effectively prevented, and the pure water is saved.
The above description is only a preferred embodiment of the present invention, and those skilled in the art may still modify the described embodiment without departing from the implementation principle of the present invention, and the corresponding modifications should also be regarded as the protection scope of the present invention.
