Constant-pressure sterilization water purifier for supplying mineral water

Abstract

The invention relates to constant-pressure sterilization water purifiers for supplying mineral water and particularly relates to a constant-pressure sterilization water purifier for supplying mineral water. The technical scheme provided by the invention is as follows: the constant-pressure sterilization water purifier for supplying mineral water comprises a water pump, filter units, an RO (Reverse Osmosis) membrane treatment unit and a water storage barrel, wherein the filter units and the RO membrane treatment unit are sequentially connected with a water inlet pipe, and the water storage barrel is connected with a purified water outlet pipe of the RO membrane treatment unit; an electromagnetic valve is arranged on a water inlet pipe of the RO membrane treatment unit, a water return pipe is further connected to a wastewater pipe of the RO membrane treatment unit and connects the wastewater pipe of the RO membrane treatment unit and a water inlet end in front of the electromagnetic valve of the water inlet pipe, and a water outlet end of the corresponding filter unit is connected with a water outlet pipe so as to be capable of directly discharging outlet water of the filter units. The constant-pressure sterilization water purifier for supplying mineral water has the beneficial effects that the service life of an RO membrane is prolonged, and the energy consumption and wastewater yield are lowered.

Description

technical field [0001] The invention relates to a sterilization constant pressure water purifier for providing mineral water, in particular to a sterilization constant pressure water purifier for providing mineral water. Background technique [0002] The main problem of the current product is that the total number of colonies in the soaking test exceeds the standard. However, the existing reverse osmosis water purifiers do not have a filter element to kill the colonies, so that the total number of colonies will exceed the standard again when the water purified by the entire reverse osmosis water purifier enters the pressure barrel, causing harm to human health. The RO reverse osmosis membrane of the reverse osmosis water purifier has a short service time, and there is no good control over the time of replacing the RO reverse osmosis membrane, which leads to or cannot be replaced in time, or the RO reverse osmosis membrane is replaced before the service life, resulting in was...

Problems solved by technology

However, none of the existing reverse osmosis water purifiers has a filter element to kill the colonies, so that the total number of bacterial colonies will exceed the standard again when the water purified by the entire reverse osmosis water purifier enters the pressure tank, causing harm to human health. The RO reverse osmosis membrane of the reverse osmosis water purifier has a short service life, and the time for replacing the RO reverse osmosis membrane is not well controlled, resulting in either not being replaced in time, or the RO reverse osmosis membrane is replaced before the end of its service life, resulting in waste
