Water path system of water purification equipment and water purification equipment

The utility model discloses a waterway system of water purification equipment and the water purification equipment, and the waterway system of the water purification equipment comprises a composite filter element, a reverse osmosis 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 storage assembly is deformed to store water when the water inlet assembly is opened, and the water storage assembly is communicated with the water outlet end of the reverse osmosis filter element; when the water outlet end of the rear filter element and the water inlet assembly are both closed, water in the water storage assembly enters the reverse osmosis filter element through the water outlet end of the reverse osmosis filter element. According to the technical scheme of the utility model, the water storage component is adopted to wash the inside of the reverse osmosis filter element from the water outlet end of the reverse osmosis filter element, so that the ion concentration of water which is not filtered by the reverse osmosis filter element is reduced, namely, 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 is used for producing water again.
