Problems solved by technology

However, when the pressure of the raw water inlet at the inlet end of the raw water pipeline is low, due to the large pressure difference between the two ends of the return pipeline, the return water increases, causing the front pressure of the reverse osmosis membrane to drop, so that the reverse osmosis through the membrane filter element less pure water

Abstract

The invention discloses a water purifying device and a water purifier. The water purifying device comprises a membrane filter core, a first booster pump and a second booster pump, wherein the membranefilter core is provided with a water inlet, a purified water outlet and a wastewater outlet; the water inlet end of the first booster pump is connected with a raw water port, and the water outlet endof the first booster pump is connected with the water inlet of the membrane filter core; the second booster pump is serially connected to a pipeline between the first booster pump and the membrane filter core, and the water inlet end of the second booster pump is further connected with the wastewater outlet; a wastewater discharging pipe is further arranged on the wastewater outlet. According tothe technical scheme, a phenomenon of excessive reflux water flow due to excessive pressure difference between the water inlet end of the second booster pump and the wastewater outlet can be prevented.

Description

technical field [0001] The invention relates to the field of water purification, in particular to a water purification device and a water purifier. Background technique [0002] In order to realize the water-saving function of the reverse osmosis water purification system, the waste water backflow method is usually adopted, that is, the pipeline connected to the waste water outlet of the membrane filter element is divided into two lines, the waste water line and the return line, in which the waste water line extends to the outside and is used In order to discharge waste water directly, the return line is connected to the raw water line to return part of the waste water, so as to save water while ensuring the life of the membrane filter element. However, when the pressure of the raw water inlet at the inlet end of the raw water pipeline is low, due to the large pressure difference between the two ends of the return pipeline, the return water increases, causing the front press...
