Description

Safe ultraviolet sterilization and disinfection lamp

Technical Field

The utility model relates to a disinfecting and sterilizing equipment especially relates to a safe ultraviolet sterilization sterilamp.

Background

Pathogenic bacteria or viruses of many diseases can be airborne, especially the transmission of infectious diseases, and pose a serious threat to human life and health. The existing means for eliminating virus and bacteria in the air of a small closed space is limited, and mainly adopts a spraying mode, namely chemical disinfectant (powder) is sprayed or sprayed to spread in the air through vaporization, but the mode is easy to generate over-disinfection, and the disinfectant (powder) is not directly used for spraying and disinfecting the whole body of a person, and the chemical disinfectant is not used for disinfecting the air of the closed space under the condition of someone because the chemical disinfectant is harmful to the human body. The other mode for disinfecting indoor air is to directly irradiate and disinfect the indoor air through an ultraviolet fluorescent lamp, but in the disinfection mode, people cannot live indoors to prevent ultraviolet rays from damaging eyes, skin and the like of human bodies, and the mode can generate ozone for disinfection and is harmful to human bodies, so that the mode cannot work in real time in a manned environment, once the mode stops working, the indoor air quality can be quickly restored to the level before purification, and the disinfection and disinfection effects of the mode disappear. Therefore, how to scientifically and effectively kill the viruses and bacteria in the air and purify the air is an important subject.

Airborne transmission has become a critical feature for many epidemics, and new coronaviruses are no exception. People infected with the new coronavirus, even in the asymptomatic early stage, exhale a large amount of aerosol containing the new coronavirus. Crowded indoor spaces collect these aerosols, resulting in higher exposure and risk of infection. To address this challenge, applicants have previously developed a range of UVC air sanitization products for epidemic prevention that combine electrostatic adsorption filtration with UV-C light disinfection to safely and consistently eliminate airborne infectious aerosols and thereby reduce the risk of infection. The filter screen can be taken out and cleaned by the product so as to be reused, but because the product is basically in a normally powered state, if the power supply is not switched to extract the filter screen, once the machine is in a working state, ultraviolet rays can leak from the pull opening of the filter screen, and the risk potential hazard of personal injury is caused to the skin and eyes of maintainers and field personnel. In addition, due to the fact that the existing product is different in environment and installation mode, under the condition that space is narrow or dust in the environment is more, the air inlet is blocked and blocked, and unsmooth air inlet is caused, and therefore the sterilization and disinfection effects are weakened. Moreover, the existing product can be vertically hung in a wall or the like through a lock hole to be vertically installed, but if the existing product is obliquely or horizontally installed, the equipment has the risk of slipping from the lock hole.
