A high-efficiency air sterilizer

Abstract

The invention relates to a high-efficiency air disinfection machine, which includes a housing and a germicidal lamp assembly arranged in the housing. The germicidal lamp assembly includes a first reflector, a second reflector, a third reflector, a fourth reflector and a sterilizing The lamp tube, the cross sections of the first reflector and the second reflector are both arc-shaped, and they are arranged opposite to each other to form a circular sterilization cavity. The first reflector, the second reflector and the third reflector, the fourth reflector The reflectors are located on concentric circles. The first reflector and the second reflector together form a semi-closed circular sterilizing cavity, and the sterilizing lamp tube is placed in the sterilizing cavity, which not only enables the light to be reflected in a wide range as much as possible, but also helps to improve the uniformity of illumination. In order to eliminate the dead angle of light and improve the bactericidal effect, the third reflector and the fourth reflector can not only cooperate with the first reflector and the second reflector to achieve more uniform reflection of light, but also avoid direct contact between light and the plastic shell. The plastic shell is used for protection to avoid or reduce the degree of aging.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a high-efficiency air sterilizer capable of sterilizing air through light sterilization and particle filtration. Background technique [0002] About 80% of people's life is spent indoors. Therefore, the quality of the indoor environment directly affects human health. However, indoor microbial contamination is ubiquitous, especially in places such as kitchens, restaurants, food production workshops, warehouses, stations, and movie theaters. There are a large number of microorganisms such as bacteria and viruses. The relatively closed environment provides opportunities for the spread of pathogenic microorganisms. [0003] The use of ultraviolet disinfection lamps for sterilization and disinfection is a commonly used method at present. Ultraviolet disinfection lamps can effectively kill pathogenic microorganisms such as bacterial propagules, spores, coronaviruses, fungi, a...
