Personal hygiene during the new crown epidemic is particularly important, in all public places people will wear disposable masks, but there are three problems, one: for the limited time of use of masks do not know, most think that a mask can take a day or even longer. Second, masks are not enough in public environment. Third: The mask is discarded for fear of being recycled by others. The solution to the above three problems is proposed. Safety is a mask redesign for use in public space environment. It can provide mask supply in public space environment and provide mask supply for users who want to replace masks but do not have masks. After using the mask for a period of time, the edge of the mask will gradually change color to remind the user to replace the mask in time. Tearing off the red edge of the used mask from the ear strap can destroy the complete shape of the mask, thus avoiding the recycling of the mask by some criminals and again. [Safety] The design adopts a roll-type mask packaging design, which can provide mask supply to the public environment space to the maximum extent. An ultraviolet disinfection device is designed inside the chassis to sterilize temporary masks for 24 hours. The design is also suitable for supermarkets, hospitals, and other crowded places.
