Water path system of water purification equipment and water purification equipment

The utility model discloses a water purification equipment waterway system and water purification equipment, the water purification equipment waterway system comprises a composite filter element, the composite filter element comprises a front filter element and a rear filter element; the water inlet end of the reverse osmosis filter element is communicated with the water outlet end of the front filter element, and the water outlet end of the reverse osmosis filter element is communicated with the water inlet end of the rear filter element; the water inlet assembly is used for connecting or disconnecting a flow path between the water outlet end of the front filter element and the water inlet end of the reverse osmosis filter element; the water outlet end of the reverse osmosis filter element is further communicated with the water inlet end of the reverse osmosis filter element, and the backflow assembly is used for connecting or disconnecting a flow path between the water outlet end and the water inlet end of the reverse osmosis filter element. According to the technical scheme, the backflow assembly is adopted to wash the interior of the reverse osmosis filter element, so that the TDS value of water retained in the water path system is reduced, and the first cup of water has a lower TDS value when the whole water path system produces water again.
