A bacteriostatic constant-pressure water purifier providing mineral water

Abstract

The invention relates to a bacteriostatic constant-pressure water purifier providing mineral water and particularly relates to a bacteriostatic constant-pressure water purifier providing mineral water. According to the technical scheme, the water purifier comprises a water pump, a filtering unit, an RO (reverse osmosis) membrane treatment unit, and a water storage barrel connected to a purified water discharging pipe of the RO (reverse osmosis) membrane treatment unit, wherein the filtering unit and the RO (reverse osmosis) membrane treatment unit are connected to a water feeding pipe in order. The water feeding pipe of the RO (reverse osmosis) membrane treatment unit is provided with a magnetic valve. The water purifier is characterized in that a waste water pipe of the RO (reverse osmosis) membrane treatment unit is connected to a water return pipe, the water return pipe is connected from the waste water pipe of the RO (reverse osmosis) membrane treatment unit to a water feeding end before the magnetic valve of the water feeding pipe, a water discharging end of the filtering unit is provided with a water discharging pipe and can directly discharge effluent of the filtering unit, and shells of the filtering unit and the RO (reverse osmosis) membrane treatment unit are made of a material comprising KDF, activated carbon and medical stone. The water purifier achieves beneficial effects of prolonging the service lifetime of RO (reverse osmosis) membranes, providing mineral water and purified water, achieving bacteriostasis and reducing energy consumption and the output of waste water.

Description

technical field [0001] The invention relates to an antibacterial and constant-pressure water purifier for providing mineral water, in particular to an antibacterial and constant-pressure water purifier for providing mineral water. Background technique [0002] The main problem existing in the current product is that the total number of colonies in the soaking test exceeds the standard. 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 there is no good control over the time to replace the RO reverse osmosis membrane, resulting in either not being replaced in time, or the RO reverse osmosis membrane being replaced before its ...

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
