Description

Technical Field

[0001] The utility model relates to the technical field of disinfection and sterilization of pure water machines, in particular to a disinfection and sterilization mechanism of a pure water machine. Background Art

[0002] A pure water machine refers to a water purification device that removes or reduces the salt in water to a certain level. The resistivity of the pure water produced is generally 1.0-10.0μS / cm, and the salt content is 1-5mg / L. A pure water machine is a water purification device that uses a multi-stage filter element to purify water. The treatment mostly uses physical methods such as filtration, adsorption and reverse osmosis without adding chemical substances. According to the water purification accuracy of the pure water machine, it can be divided into two categories: daily drinking pure water machine, also called household pure water machine, and laboratory pure water machine that can meet the laboratory pure water quality requirements.

[0003] Existing pure water machines generally use ultraviolet sterilizers for sterilization and disinfection. Pure water is introduced into the sterilizer through a pipe, and then sterilized by ultraviolet irradiation. Finally, the sterilized pure water is output for use.

[0004] However, the existing ultraviolet sterilizers still have shortcomings during use. The suspended particles in the water will scatter ultraviolet rays, reduce the penetration of ultraviolet rays, and thus weaken the sterilization effect. At the same time, colored substances in the water (such as organic matter, rust, etc.) will also absorb ultraviolet rays and reduce the intensity of ultraviolet rays, thereby weakening the sterilization effect and reducing the practicality of the ultraviolet sterilizer. Utility Model Content

At the same time, colored substances in the water (such as organic matter, rust, etc.) will also absorb ultraviolet rays, reduce the irradiation intensity of ultraviolet rays, thereby weakening the sterilization effect and reducing the practicality of the ultraviolet sterilizer.
