The water purifier of this embodiment carries out the desalination water purification through the water purification system that a pure waste water proportion is invariable, and this water purification system is provided with the EDR unit, controls the thick water stopper of thick water velocity of flow, adjusts the flow control valve of the pure water velocity of flow and promotes the booster pump of the raw water velocity of flow, and booster pump, thick water stopper and flow control valve are connected with the EDR unit respectively. The booster pump selects the pressure mode that corresponds to change the water velocity that the raw water got into the EDR unit according to the temperature of pure water, and water purification system carries out the desalination water purification to the raw water through the EDR unit, exerts certain pressure to the raw water through the booster pump that sets up before the EDR unit, combines the flow control valve of EDR unit delivery port department to regulate and control the flow of the product water of EDR unit, makes the pure useless proportion of water purification system's product water invariable, improves user's use and experiences.
It should be finally noted that the above embodiments are only intended to illustrate the technical solutions of the present invention and not to limit the scope of the present invention, and although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention can be modified or replaced with equivalents without departing from the spirit and scope of the technical solutions of the present invention.
