Problems solved by technology

[0002] At present, with the development of society, people pay more and more attention to health issues. Since tap water contains many substances that are not conducive to health, more and more people will install water purification equipment in their homes to filter tap water; currently The water purification equipment mainly relies on the reverse osmosis membrane (RO membrane) to filter the tap water. The water purification equipment uses the RO membrane to separate the water in the tap water from impurities such as inorganic salts, heavy metal ions, organic matter, colloids, bacteria and viruses under pressure. ;During the standby process of the water purification equipment, there are tap water, waste water and pure water in the RO membrane filter element at the same time, wherein the raw water and waste water are both in front of the membrane of the RO membrane filter element, while the pure water is behind the membrane of the RO membrane filter element, and the tap water The total dissolved solids (TDS) value in wastewater and wastewater is much higher than the TDS value of pure water, so when the water purification equipment is on standby for a long time, the ions in tap water and wastewater will gradually diffuse into the pure water, thus making the pure water The TDS value of the water will increase; when the water purification equipment is started next time, the TDS value of the water in the front section will be relatively high, which will affect the health of users

Abstract

The invention discloses a water purifier waterway system capable of backwashing. The system comprises a composite filter element, wherein a first filter module is arranged in a first accommodating cavity of the composite filter element, and a second filter module and an air bag are arranged in a second accommodating cavity of the composite filter element; a primary filtering branch which is connected to a primary filtering water outlet and the water inlet end of an RO membrane filter element; a secondary filtering branch which is connected to the water outlet end of the RO membrane filter element and a pure water inlet; a water outlet pipe which is connected to a purified water outlet and a water taking device; a water inlet valve which is mounted on the primary filtering branch; a supercharging device which is mounted on the primary filtering branch; and a reverse osmosis check valve which is arranged on the secondary filtering branch; wherein the reverse osmosis check valve is used for forward conduction and reverse throttling; the air bag is used for providing pressure for the second accommodating cavity when the water taking device is closed so that water in the second accommodating cavity reversely flows into the RO membrane filter element through the secondary filtering branch, and the RO membrane filter element is flushed. According to the system, the RO membrane can bebackwashed in time so that the problem that the TDS value of first-section discharged water is relatively high after long-time standby is avoided, and the service life of the RO membrane filter element is effectively prolonged.
