Water purification equipment capable of prolonging service life of reverse osmosis filter element

The utility model belongs to the field of water purification equipment, and particularly relates to water purification equipment capable of prolonging the service life of a reverse osmosis filter element. Compared with a conventional water path structure, the water path structure in the water purification equipment has the advantages that the circulating water path communicated with the water inlet end of the booster pump is added, insoluble salts deposited on the surface of a reverse osmosis membrane can be effectively washed away, the service life of a reverse osmosis filter element is prolonged, the water outlet end of the circulating water path is a high-pressure section, and the service life of the reverse osmosis filter element is prolonged. The water inlet end of the booster pump is a low-pressure section, and pressure difference exists between the water outlet end of the circulating water path and the water inlet end of the booster pump, so that backflow water in the circulating water path flows into
