Problems solved by technology

Chemical sterilization is mainly to dissolve sterilizing materials into water for sterilization. The problem with this method is that the bactericidal materials used will dissolve into clean water to form new pollution and cause new damage to the human body; the other is Physical sterilization, such as ultraviolet lamp sterilization method, this method can only sterilize when the water flows through the sterilizing device, but it is difficult to remove bacteria existing in other parts such as water purification pipelines and water storage tanks, and cannot inhibit The growth of bacteria, and precisely because of the existence and reproduction of these bacteria, the purified water is polluted again, and the bacterial content in the final purified water exceeds the standard

Embodiment 1

[0034] The present invention provides a method for preparing sterile purified water, specifically including a closed sterilization unit 92, the sterilization unit 92 includes a sterilization filter 5 and a water purification storage and discharge unit 7, the front end of the sterilization filter 5 Connected to the clean water outlet of the bacteria isolation unit 91, the rear end of the sterilization filter element 5 is connected to the clean water storage and discharge unit 7. The clean water storage and discharge unit 7 includes a water purification faucet 9. The sterilization material in the sterilization filter element 5 is A food-grade, water-soluble broad-spectrum sterilization material, the method includes the following steps:

[0035] S1, sterilization; the water purification faucet 9 is closed, the purified water flowing through the bacteria isolation unit 91 flows into the sterilization unit 92, and dissolves the sterilization material in the sterilization filter 5 to fo...

Embodiment 2

[0050] Such as figure 1 with 2 As shown, the present invention provides a reverse osmosis water purifier using this method for preparing sterile water purification, including a pre-filter unit 90 and a control board 81, and an active water inlet is provided at the front end of the pre-filter unit 90 , The rear end of the pre-filter unit 90 is connected to the front end of the bacteria isolation unit 91, and the control board 81 is electrically connected to the high-voltage switch 4. The control board 81 can detect the state of the high-pressure switch 4 and thereby control the start and stop of the booster pump 1.

[0051] By setting up the pre-filtration unit 90, the source water can be subjected to preliminary filtration and purification treatment to reduce the working pressure of the reverse osmosis membrane unit 2, improve the efficiency of the reverse osmosis membrane unit 2 in isolating bacteria and producing purified water, and extend the reverse osmosis membrane The servi...

Abstract

The invention relates to a method for preparing aseptic purified water and a reverse osmosis water purifier employing the same; the method comprises: isolating germs and impurities in water from purified water, sterilizing a purified water storage and discharge unit, and preparing the purified water; by using the method, germs and impurities can be avoided entering the purified water storage and discharge unit, the chances for germs originally and possibly present in the purified water storage and discharge unit to grow and breed can be comprehensively avoided, an aseptic environment is formed in the purified water storage and discharge unit with the unit kept in aseptic state, and therefore contamination and growth of germs in the purified water environment are substantially avoided and aseptic purified water is produced; in addition, after sterilization, by flushing and discharging sterilizing materials, no residual sterilizing materials are left in the purified water storage and discharge unit, and the produced purified water is free of sterilizing materials.

Description

Technical field [0001] The present invention relates to the technical field of water quality purification, in particular to a method for preparing sterile purified water and a reverse osmosis water purifier using the method. Background technique [0002] At present, excessive bacteria is a common problem in the water purifier industry. The popular water purification and sterilization methods on the market are roughly divided into two categories, one is chemical sterilization and the other is physical sterilization. Chemical sterilization is mainly to dissolve sterilizing materials into the water for sterilization. The problem with this method is that the sterilizing materials used will dissolve into the purified water to form new pollution and cause new harm to the human body; the other is Physical sterilization, such as the ultraviolet lamp sterilization method, this method can only sterilize the water flow through the sterilization device, and it is difficult to remove the bact...
