Ultraviolet LED (Light-Emitting Diode) sterilizer for sterilizing stationary liquid

Abstract

The invention relates to an ultraviolet LED (Light-Emitting Diode) sterilizer for sterilizing a stationary liquid. The ultraviolet LED sterilizer comprises a base 1, an electric protection cover 8 and a sterilization device, wherein the base 1 is hollow, an inner sealing ring channel and an inner sealing ring 4 are arranged on the inner side of a base wall 9, and an external thread 13 is arranged outside the base wall; the electric protection cover 8 is provided with a matched internal thread 14, an extending compression structure 15 is arranged in the middle of the electric protection cover 8; a transparent pressure sheet 3 is arranged on the inner sealing ring 4 and provided with an ultraviolet lamp panel 2, the transparent pressure sheet 3 is compressed and sealed by virtue of the compression structure 15 of the electric protection cover 8 and the inner sealing ring 4, and the ultraviolet lamp panel 2 is fixedly arranged between the electric protection cover 8 and the transparent pressure sheet 3. The ultraviolet LED sterilizer can be used for effectively sterilizing a stationary water body only by one light source, is less in energy consumption, long in service life, simple in structure, and simple and convenient to install, and can be arranged on a container wall by a compression nut.

Description

【Technical field】 [0001] The invention relates to a sterilizing device, in particular to a sterilizer suitable for sterilizing static liquids. 【Background technique】 [0002] The liquid stored in a static state for a long time is easy to breed bacteria, especially the water storage tank of the water dispenser or water purifier. Since the water in the water storage tank is generally in a static state, a large number of bacteria will grow if it is not used for a long time, which will affect the quality of drinking water. Therefore, it is necessary to sterilize the water in the water storage tank, and ultraviolet sterilization is a commonly used sterilization method. [0003] Traditional ultraviolet sterilizers generally use mercury lamps to generate ultraviolet rays, which sterilize liquids through continuous irradiation. The mercury lamp type ultraviolet sterilizer has the following disadvantages: complex structure, large volume, and cannot be flexibly installed inside the m...

AI Technical Summary

Problems solved by technology

The mercury lamp type ultraviolet sterilizer has the following disadvantages: complex structure, large volume, and cannot be flexibly installed inside the machine; Ultraviolet light consumes a lot of power during operation, and its life is affected by the number of switches; mercury lamp type ultraviolet sterilizers are mostly used for pipeline sterilization, that is, they can only sterilize the liquid flowing through it

However, although the LED ultraviolet germicidal lamp can sterilize static water bodies, its structure is complex, especially the light source part uses InGaN / AlGaN and MgZnO / ZnO heterojunction and LED, so it has its limitations when used
