Continuous reverse osmosis household water purification device and household water purification machine

A continuous reverse osmosis household water purification device relates to the field of water treatment and comprises a booster pump, a first membrane desalination unit and a second membrane desalination unit, the first membrane desalination unit is provided with a first water inlet, a first concentrated water outlet and a first produced water outlet, and the first produced water outlet is communicated with a second water inlet of the second membrane desalination unit. After the first-stage membrane desalination treatment, the produced water is conveyed to the second membrane desalination unit for further treatment, so that the salt content in the produced water is further reduced. The continuous reverse osmosis household water purification device is reasonable in arrangement and simple to operate, the requirements on a reverse osmosis membrane are reduced while high recovery rate and high desalination rate are achieved through a series continuous membrane desalination mode, and the reverse osmosis membrane
