Air disinfection machine

Abstract

The invention relates to an air disinfection machine which comprises a shell and a sterilization lamp assembly arranged in the shell. An air inlet is formed in the lower portion of the shell, and an air outlet is formed in the top of the shell. The sterilization lamp assembly is located between the air inlet and the air outlet and comprises a sleeve and sterilization lamp tubes, wherein the sleeve is a metal cylinder which is vertically through, the inner wall of the shell sleeves the metal cylinder, the sterilization lamp tubes are vertically arranged in the metal cylinder, and a first light reflecting surface corresponding to the sterilization lamp tubes is formed on the inner wall of the metal cylinder. According to the air disinfection machine, the metal sleeve is arranged at the position corresponding to the sterilization lamp tubes, the sleeve can protect the plastic shell on the outer side of the sleeve, and the phenomenon that aging happens due to the fact that the shell makes contact with sterilization light rays for a long time is avoided. Meanwhile, the inner wall surface of the metal sleeve can form the first light reflecting surface which can reflect the sterilization light rays, the first light reflecting surface is annular, the light rays can be reflected for multiple times, the illumination uniformity can be improved advantageously, and therefore the illumination dead angle is eliminated, and the sterilization effect is improved.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to an air sterilizer capable of sterilizing air through light sterilization and particle filtration. Background technique [0002] About 80% of people's life is spent indoors, so the quality of the indoor environment directly affects human health. However, indoor microbial contamination is prevalent, especially in kitchens, restaurants, food production workshops, warehouses, stations and cinemas, where bacteria, viruses and other microorganisms exist in large numbers. The relatively closed environment provides opportunities for the spread of pathogenic microorganisms. [0003] The use of ultraviolet disinfection lamps for sterilization and disinfection is currently a commonly used method. UV disinfection lamps can effectively kill bacterial propagules, spores, coronaviruses, fungi, chlamydia and other pathogenic microorganisms. For example, the Chinese utility model paten...
