Abstract
The invention discloses an overflowing water sterilizing device with a UVCLED light source, and relates to the technical field of drinking water sterilization.A drinking water is introduced into an inner cavity of a slow flow bottom cylinder from a water inlet pipe, an ultraviolet LED lamp panel works to release ultraviolet rays, the ultraviolet rays pass through a transparent waterproof shell to enter the drinking water to sterilize and disinfect the drinking water, and the drinking water is finally discharged from a water outlet pipe; when the ultraviolet LED lamp panel works, the heat released by the ultraviolet LED lamp panel is transferred to the plugging nut through the LED lamp panel base and finally transferred to water; this sterilizing equipment utilizes dark ultraviolet UVCLED technique to disinfect with overflowing water, and bactericidal effect is good, and the heat transfer to the aquatic with ultraviolet LED lamp plate release in the sterilization process in addition realizes the quick heat dissipation of ultraviolet LED lamp plate, can protect the shutoff nut through rust-resistant heat dissipation coating can not rusted by the water corrosion, prolongs the life of LED submodule piece, avoids the scale to influence quality of water simultaneously.
Description

at present, for the secondary pollution of purified water, the most common problem is that bacterial colonies exceed the standard, in the drinking water standard GB5749-2006 of Ministry of health, the total number of the bacterial colonies in drinking water is definitely specified to be not more than 100cfu/mL, and the total number of the bacterial colonies of the purified water subjected to secondary pollution is usually far higher than the value, so that the health of users drinking water is damaged, therefore, measures are necessary to be taken, and the bacterial colonies in the purified water are sterilized and controlled to protect the water quality;
the existing relatively mature bacterial colony sterilizing technology in the market comprises ozone and ultraviolet sterilizing technology, wherein the ozone sterilizing technology inactivates bacterial viruses by utilizing the strong oxidizing property of ozone, but because the ozone has certain irritation to human respiratory mucosa, the concentration and dosage need to be accurately controlled in the using process, the mode is more applied to large-scale water plants or centralized water making at present and is rarely applied to consumer-grade application occasions, the other sterilizing technology is the ultraviolet sterilizing technology, and because the ultraviolet has the characteristics of broad-spectrum sterilization, no color, no odor and no by-product, the method is an ideal choice for consumer-grade sterilizing products;
at present, ultraviolet mercury lamps are more in the market, most ultraviolet sterilizing devices for flowing purified water adopt ultraviolet light sources, and ultraviolet rays are generated by a technology of discharging under high pressure of mercury vapor, because materials contain mercury, the environment is greatly damaged in use and subsequent waste treatment occasions, currently, along with the formal effective water-good convention in 2020 in China, the market urgently needs the upgrading and updating of the ultraviolet sterilizing technology for the trend of gradually going to the comprehensive prohibition of products containing mercury;
the novel generation light source adopting the deep ultraviolet UVC LED technology provides a chance for the regeneration of the ultraviolet sterilization technology, the ultraviolet LED has important application potential in the ultraviolet sterilization occasion due to the characteristics of small volume, no lead and no mercury in materials, environmental friendliness and the like, but the high-power ultraviolet LED has lower luminous efficiency (ultraviolet power/total power) due to the current technical limit of the ultraviolet LED, the high-power ultraviolet LED faces serious LED heating problem in the application process, the service life and the use effect of the product are reduced, a complex heat dissipation system needs to be considered in the application, and the cost of the sterilization system is invisibly increased;
in view of the above technical drawbacks, a solution is proposed.
