Novel water purifying machine with pure-water-membrane-soaking function during stopping resting

Abstract

The invention discloses a novel water purifying machine with the pure-water-membrane-soaking function during stopping resting. The novel water purifying machine comprises a water feeding electric valve, a filter element mechanism, a boosting pump, a RO membrane module, a check valve, an one-in-two-out electric valve, a pure-water storage tank, a high-voltage switch, a pure water faucet and a micro-wastewater-ratio-combination electromagnetic valve which are sequentially connected through a pipe. The water feeding electric valve is connected with a water inlet of the boosting pump through the filter element mechanism, a water outlet of the boosting pump is connected with the RO membrane module, and a pure water outlet of the RO membrane module is connected with a water returning pipe and a water discharging pipe; the water returning pipe is provided with the check valve and connected with the water inlet of the boosting pump; the water discharging pipe is provided with the one-in-two-out electric valve, the pure-water storage tank, the high-voltage switch and the pure water faucet; a thick water outlet of the RO membrane module is connected with a sewer through the micro-wastewater-ratio-combination electromagnetic valve. By means of the novel water purifying machine with the pure-water-membrane-soaking function during stopping resting, in the using process of a traditional RO water purifying machine, the problem that as the traditional RO water purifying machine is located in thick-water membrane soaking during resting stopping, the initial water-making TDS value of the RO water purifying machine is higher than the standard value is solved, and the membrane-surface scaling problem caused when a RO membrane sheet is soaked with thick water for a long time is solved.

Description

technical field [0001] The invention relates to the technical field of water purifiers, in particular to a water purifier using pure water bubble film technology. Background technique [0002] China is a country with scarce water resources. The limited water source is seriously polluted, and the water environment continues to deteriorate, seriously threatening the safety of drinking water in urban and rural areas. Therefore, surface water and groundwater must be purified before they can be used as drinking water. Now the core drinking water treatment technology is membrane filtration technology. One of them is reverse osmosis membrane (RO membrane) filtration. The filter pore size is 0.0001 micron, which can completely remove all harmful substances in water, and only keep water molecules to produce pure water. Its effect is the best solution in membrane treatment, but its One of the biggest disadvantages is that the RO membrane is soaked in concentrated water for a long ti...

Problems solved by technology

[0003] The purpose of the present invention is to provide a new type of water purifier with the function of pure water bubble film when the machine is at rest, so as to solve the RO problem caused by the thick water bubble film in the static shutdown state during the use of traditional RO water purifiers. The problem that the initial water TDS value of the water purifier is higher than the standard value, and the problem of fouling on the membrane surface caused by the long-term immersion of the RO membrane in concentrated water
