Embodiment 1

[0025] Such as figure 1 and figure 2As shown, the present invention includes a three-way valve group 121, a pressure reducing valve 123, a water cutoff solenoid valve 122, a primary filter group 102, a secondary filter group 103, a tertiary filter group 104, a booster pump 107, a reverse Permeation filter group 109, one-way valve 113, post filter group 116 and water purification faucet 117, the other two interfaces of three-way valve group 121 are respectively connected with raw water pipeline 101 and tap water faucet 120, and the pump outlet of booster pump 107 108 is connected with reverse osmosis filter group 109. The reverse osmosis filter set 109 is provided with a concentrated water port 110 and a clean water port 111 , and a one-way valve 113 is connected to the clean water port 111 of the reverse osmosis filter set 109 . The present invention also includes a high-pressure switch 115, a water storage bucket, and a combination valve 112, and the connection pipeline be...

Embodiment 2

[0031] Such as image 3 and Figure 4 As shown, in this embodiment, the combined valve 112 in Embodiment 1 is replaced by an electric control valve 202, and the water outlet 119 of the clean water chamber of the water storage bucket passes through the connecting pipe between the pipeline and the high-pressure switch 115 and the post-filter group 116 After the road is connected, a junction is formed, and a switch 201 is provided on the pipeline between the junction and the rear filter group 116. When the clean water faucet 117 discharges water, the electric control valve is controlled by the induction of the switch 201 to the flow or water pressure. 202 start and stop. The electronically controlled valve 202 in this embodiment can be an independent component, or can be integrated on the reverse osmosis filter group 109, and can also be integrated on the water storage tank. The electric control valve 202 comprises an electric control valve seat 301 and a cover 307, the electri...

Abstract

The invention discloses a household water purifier which comprises a booster pump, a reverse osmosis filter unit, a one-way valve and a post-filtering unit which are connected in sequence, wherein the reverse osmosis filter unit is provided with a concentrated water gap and a purified water gap, the booster pump is connected with a raw waster pipeline, the one-way valve is connected with the purified water gap of the reverse osmosis filter unit, and a connecting pipeline between the one-way valve and the post-filtering unit is connected with a water storage bucket and a high voltage switch respectively. The household water purifier further comprises a control valve; and a water inlet of the control valve is connected with the concentrated water gap of the reverse osmosis filter unit, a water outlet of the control valve is connected with a water gap of a pressure cavity of the water storage bucket, and a drain opening of the control valve is connected between the raw water pipeline anda connecting pipeline of the booster pump. By adopting the structure, the household water purifier has a simple integral structure and is easy for realization, the self-washing of the reverse osmosisfilter unit can be automatically completed during the outputting process of purified water, so that a washing solenoid valve is saved, and the purpose of recycling washing water can be achieved.

Description

technical field [0001] The invention relates to a water treatment system, in particular to a household pure water machine. Background technique [0002] With the development of the pure water machine industry, more and more families use pure water machines, among which the pure water machine system that is convenient and beneficial to the people is more favored by people. Chinese patent application number 200910164319.7, the patent publication titled "A New Type of Pure Water Machine" provides a pure water machine that uses a hydraulic water storage tank for water storage and water supply. The pure water machine is small in size and low in cost, but the pure water machine needs to start and stop the flushing solenoid valve to release the flushing water to complete the flushing of the reverse osmosis filter group, and the water for flushing the reverse osmosis filter group is directly discharged, which is a waste of resources. Contents of the invention [0003] The purpose...
