Description

UVC-LED disinfection and sterilization device

Technical Field

The demand of people for sanitary conditions increases with the rise of living standard, and therefore, the demand of consumers for household sterilization is not only real, but also very huge. The miniaturization of the UVC LED chip and the module enables the sterilization component to have a wide enough design space, the small size enables the sterilization component to be sufficiently implanted into various household appliances for use (such as a refrigerator, an air conditioner and a washing machine), the sterilization component can be carried with people (such as a water cup, a lunch box and a toothbrush) depending on various living utensils, due to the appearance of the UVC LED, a plurality of sterilization dead corners in the past can be covered, and the crowd with specific requirements on sanitary conditions is also met.

Currently, the design of related mainstream UVC modules on the market generally adopts laminar flow type and natural flow type.

Laminar flow type: light source and heat dissipation module install and shine the sterilization in module one end, and rivers get into the back rectification from the rectifying region and change from the torrent into the laminar flow. The sterilization cavity is a long cylinder, so that the surface uniformity and penetrability of light are improved. The volume of the rectifying area is too large, the outer cavity can not be sterilized at the irradiation dead angle, and the flow of water treatment is not large enough.
