Water purifier system with flush valve

Abstract

The invention discloses a water purifier system with a flush valve. The water purifier system comprises a first filter group, a second filter group, a water cut-off valve, a booster pump, a large-fluxreverse osmosis filter group and a high-pressure switch, a raw water pipe is sequentially communicated with the first filter group, the water cut-off valve and the second filter group through pipelines; a water outlet of the second filter group is sequentially communicated with the booster pump and the large-flux reverse osmosis filter group through pipelines; the water outlet end of the large-flux reverse osmosis group is communicated with a purified water pipe and a concentrated water pipe, the purified water pipe is communicated with the high-pressure switch, the high-pressure switch is communicated with a purified water faucet, the concentrated water pipe is communicated with a concentrated water inlet of a flush valve, the upper end of the flush valve is communicated with the purified water pipe serially connected with the high-pressure switch purified water faucet, and a water outlet of the flush valve is communicated with a concentrated water drain pipe. And the structure is simple, the size is relatively smaller, the production process is simple, and therefore the input cost is lower.

Description

technical field [0001] The invention relates to the technical field of pure water machines, in particular to a pure water machine system with a flushing valve. Background technique [0002] With the development of the economy, the situation of water resources has deteriorated in many places. The shortage and pollution of water resources have become more and more serious, and the problem of drinking water safety for urban residents has become prominent. Aiming at the secondary pollution of tap water in cities and the persistent presence of harmful substances in tap water due to source water pollution, more and more household water purifiers with reverse osmosis membrane as the core filter unit have entered thousands of households. The existing household pure water machine uses the reverse osmosis membrane as the core filter unit. After multi-stage pretreatment and pressurization of tap water, it enters the reverse osmosis membrane unit. The pure water produced can fully meet ...

AI Technical Summary

Problems solved by technology

[0003] At present, in the pure water machine system, a flushing solenoid valve is generally installed on the concentrated water drain pipe to control the flushing of the reverse osmosis membrane unit. After the pure water machine system stops water production, the flushing solenoid valve is opened to allow a large flow of concentrated water to flow out. Then flush the reverse osmosis membrane unit, but the flushing solenoid valve with this configuration has a complex structure, high cost, large volume, and high failure rate in the later stage, so more lines need to be arranged to control the flushing solenoid valve
