Sterilization and disinfection lamp

Abstract

The invention discloses a sterilization and disinfection lamp. The sterilization and disinfection lamp comprises a lamp body assembly, an air inlet hole (100) and an air outlet hole are formed in the lamp body assembly, an ultraviolet light-emitting device (5), a fan (6), a circuit board assembly (7) and an air filtering device (8) are arranged in the lamp body assembly, and the circuit board assembly (7) is electrically connected to the ultraviolet light-emitting device (5) and the fan (6), respectively; and the fan (6) is used for sucking outside air into the lamp body assembly from the air inlet hole (100) and discharging the air from the air outlet hole, so that continuous air flowing is formed in the lamp body assembly, and viruses, bacteria and tiny particles are filtered and intercepted by the air filtering device (8) in the air flowing process, and are sterilized and disinfected by irradiating of the ultraviolet light-emitting device (4). The invention can be widely applied to the field of sterilization and disinfection.

Description

technical field [0001] The invention relates to a sterilization and disinfection appliance, in particular to a sterilization and disinfection lamp. Background technique [0002] The pathogenic bacteria or viruses of many diseases can be transmitted through the air, especially the transmission of infectious diseases, which poses a serious threat to human life and health. Existing methods for eliminating viruses and bacteria in the air are limited, mainly by spraying, that is, chemical disinfectants (powder) are sprayed into the air through vaporization spraying or spraying, but this method is prone to over-disinfection and should not be used. Directly use disinfectant (powder) to spray and disinfect the whole body of personnel, and chemical disinfectants should not be used to disinfect indoor air under the condition of people, because chemical disinfectants are harmful to human body. Another way to sterilize indoor air is to irradiate and sterilize directly through ultraviol...

Problems solved by technology

Existing methods for eliminating viruses and bacteria in the air are limited, mainly by spraying, that is, chemical disinfectants (powder) are sprayed into the air through vaporization spraying or spraying, but this method is prone to over-disinfection and should not be used. Directly use disinfectant (powder) to spray and disinfect the whole body of personnel, and chemical disinfectants should not be used to disinfect indoor air under the condition of people, because chemical disinfectants are harmful to human body

Another way to sterilize indoor air is to irradiate and sterilize directly through ultraviolet fluorescent lamps, but in this way, no one can be in the room during disinfection, so as to prevent ultraviolet rays from causing damage to human eyes and skin, and this method of sterilization will produce ozone , is also harmful to the human body, so this method cannot work in real time in an environment with people. Once the work is stopped, the indoor air quality will soon return to the level before use, and its sterilization and disinfection effects will also disappear.
