Water purification device and reverse osmosis water purifier

Abstract

The invention discloses a water purification device. The water purification device comprises a water purification module for preparing clear water and a water outlet module for controlling the clear water to flow out, wherein the water outlet module comprises a water storage device, a water tap, a pump, a first pressure switch, a first connecting pipe, a second connecting pipe, a third connecting pipe and a control circuit; the water storage device is communicated with a water outlet pipe of the water purification module through the first connecting pipe; a water inlet of the pump is communicated with the water outlet pipe of the water purification module through the second connecting pipe, and a water outlet is communicated with the water tap through the third connecting pipe; the first pressure switch is arranged on the third connecting pipe for detecting the pressure in the third connecting pipe; the control circuit is electrically connected with the pump and the first pressure switch and can control the pump to start and stop according to pressure information detected by the first pressure switch. The invention further discloses a reverse osmosis water purification machine. The water purification device disclosed by the invention realizes water production without back pressure, thereby reducing the volume of the water purification device and improving the utilization rate of running water and the safety in use.

Description

technical field [0001] The invention relates to the technical field of water purification treatment, in particular to a water purification device and a reverse osmosis water purifier. Background technique [0002] As we all know, existing reverse osmosis water purifiers (such as figure 1 shown) includes a water purification module 10' and a water outlet module 20', wherein the water outlet module 20' usually uses a pressure tank to store water and ensure water outlet pressure. The pressure tank is a kind of expansion tank. There is an air bag in the tank to divide the tank into two closed spaces. One side stores pure water and the other side stores air at a certain pressure. When the pressure tank stores pure water, the air in the tank is compressed, and when the water is drawn from the tap, the pressure in the air bag is released to press out the pure water. During the water production process of the water purification module 10', due to the air bag pressure of the pressu...

AI Technical Summary

Problems solved by technology

Due to the use of pressure tanks to store water, the overall volume is large, and there is back pressure (that is, air bag pressure), resulting in low utilization of tap water; in addition

The pressure tank itself has an air bag and is pre-filled with pressure, which is likely to cause air leakage failure or barrel explosion, so the safety of use is low
