Enhanced sterilization disinfection lamp

Abstract

The invention discloses an enhanced sterilization disinfection lamp. The enhanced sterilization disinfection lamp comprises a lamp body assembly, wherein an air inlet hole and an air outlet hole are formed in the bottom and the top of the lamp body assembly respectively; a circuit board assembly, an ultraviolet light-emitting device, a fan, a filter screen support and a negative-ion generator arearranged in the lamp body assembly; the ultraviolet light-emitting device is covered with the filter screen support, and an air filtering device is wrapped with the filter screen support. The fan sucks external air into an inner cavity of the filter screen support from the air inlet hole, the external air is filtered by the air filtering device and then discharged from the air outlet hole, when the external air flows through the air filtering device, virus, bacteria and tiny particles are filtered and intercepted by the air filtering device, and the sterilization disinfection is irradiated bythe ultraviolet light-emitting device; a negative-ion generator is used for purifying air, killing bacteria and virus; the air filtering device comprises a metal filter screen; and the negative-ion generator is located beside the air filtering device and used for enabling the metal filter screen to generate static electricity, virus, bacteria and tiny particles in the air are adsorbed through thestatic electricity, and the filtering efficiency of the air filtering device is enhanced.

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 purification, and its sterilization and detoxification effects will also disappear.
