Background technique

With the development of economic globalization, the transmission channels of viruses have gradually diversified. Killing viruses during transmission is a cost-effective and efficient means of epidemic prevention. Therefore, it is particularly important to conduct round-the-clock detection and elimination of viruses in public places. However, at this stage, many virus elimination methods are superficial and only target individual parts such as hands and shoes. It is not uncommon to only use alcohol disinfectants in public places to eliminate viruses. This method cannot guarantee a high virus elimination rate, nor can it guarantee the population utilization rate. In this case, the virus will have the opportunity to attach itself to personal belongings and spread along with people's daily activities.

Moreover, centralized disinfection methods often used in public places often cannot guarantee round-the-clock coverage, and at the same time have a greater impact on surrounding people when eliminating viruses. For example, high-power disinfection sprayers are often accompanied by loud noise, high disinfection dosage, strong smell and other problems.
