Waste water electromagnetic valve and water purifier with same

Technical Field

The utility model relates to a purifier technical field specifically, relates to waste water solenoid valve and purifier that has it.

Background

With the improvement of living standard, the requirement of people on the quality of drinking water is higher and higher. Various water purifiers appear in the market at present, and are installed on a water supply pipeline to filter and purify tap water and then supply people to drink. Reverse osmosis water purifiers are becoming more popular because the purified water produced by them is fresher, more sanitary and safer.

The reverse osmosis filter element is a core component of the reverse osmosis water purifier. The raw water is filtered by the reverse osmosis membrane to generate pure water and concentrated water according to the proportion. The pure water is conveyed to the water taking end through the pure water pipeline for users to take. The concentrated water is discharged through a concentrated water pipeline. The concentrate line is usually provided with a waste water ratio valve having a through hole with a relatively small diameter to discharge concentrate produced during water production at any time. Therefore, high pressure can be generated inside the reverse osmosis filter element, and concentrated water can be discharged.

However, this causes a problem that water inside the reverse osmosis filter element is gradually lost from the waste water ratio valve after the water purifier is in a standby state, so that a cavity is formed in the reverse osmosis filter element. When the user opens the tap to take water next time, the booster pump needs to be full of the cavity with water first, and the user can take water by the tap play, so that the phenomenon of water pause can occur, and the use experience of the user is influenced. In addition, if the inlet solenoid valve upstream of the reverse osmosis cartridge fails, it can also result in a long flow of wastewater.
