Light-gathering shielding type UV disinfection cavity

Abstract

The invention discloses a shielding type UV disinfection cavity (short for a light-gathering shielding type UV disinfection cavity) which can focus ultraviolet rays generated by a UV lamp and enhancethe ultraviolet sterilization efficiency. The disinfection cavity comprises the UV lamp, a light shield, a focusing reflection cavity, a reflection plate, an ultraviolet focusing plate, a flow guide structure, an air inlet and outlet structure, a filter screen and the like. A plurality of sets of air inlets are evenly formed in the bottom of the outer side face of the light shield, a plurality ofsets of air outlets are formed in the top of the light shield, a fan (or an external fan) is fixedly installed in the center of the air outlet end (or the air inlet end), and the UV lamp is fixedly connected with the focusing reflection cavity. The outer edge of the focusing reflection cavity is fixedly connected with the filter screen (whether the filter screen is installed or not and the type ofthe filter screen are determined according to the working environment), the top end of the filter screen is fixedly connected with the light shield, the inner side edge of the light shield is fixedlyconnected with the ultraviolet focusing plate, and a plurality of sets of focusing holes are evenly formed in the ultraviolet focusing plate. The UV disinfection cavity has the advantages of being high in sterilizing capacity, good in effect, low in dust adhesion and simple in structure, and is mainly used for killing bacteria and viruses in air. The disinfection cavity can be applied to equipment such as a central air conditioner air inlet/outlet, a central air conditioner air duct, a split air conditioner air outlet, an air purifier and an air disinfector, and has the effect of efficientlykilling the bacteria and the viruses in air in real time without harm to human bodies.

Description

technical field [0001] The invention relates to the field of ultraviolet sterilization technology, in particular to a shielded UV disinfection chamber (abbreviation: focusing and shielded UV disinfection chamber) capable of focusing ultraviolet rays generated by UV lamps to enhance ultraviolet sterilization efficiency. Background technique [0002] Traditional UV disinfection equipment has problems such as limited disinfecting scenarios, dead angles for killing, and low disinfecting efficiency. In recent years, various epidemic diseases caused by bacteria and viruses in the air have occurred frequently at home and abroad. Traditional equipment cannot maintain reliable sterilization and disinfection effects for a long time, which seriously threatens people's health. Therefore, we propose a concentrating shielding UV disinfection cavity. Contents of the invention [0003] In view of the above-mentioned deficiencies in the prior art, the object of the present invention is to...
