The mask is a powerful tool for people to keep warm and control epidemic diseases, and in the traditional use habit, due to the sanitary consideration, the mask is mostly disposable and is discarded immediately, so that two problems are brought, namely resource waste and secondary pollution, and the two problems can not cause attention of people at ordinary times, but in an extraordinary period, people have to pay attention to the mask, if the traditional use habit of 'once-used and immediately-abandoned' is still followed, a large amount of waste of the mask, tight tension of mask resources and price rising are inevitably caused, particularly, the mask which is not disinfected and discarded at will, secondary pollution and virus propagation potential safety hazards are brought, and adverse effects are brought to disease control work and citizen health.
As a result of careful observation and study, the disposable masks used at present have a chance to be reused by the user as long as they have no serious defects such as breakage and deformation, but cannot be reused directly. On one hand, the used mask has a large amount of bacterial microorganisms accumulated on the surface, and the direct use of the mask can bring serious consequences, and uncomfortable peculiar smell exists. Secondly, in the used mask, the fiber woven fabric contains a moisture component, which deteriorates the air permeability of the mask and deteriorates the use experience, and therefore, if the used mask is to be reused, it is necessary to perform a complete sterilization and drying process.
The utility model patent (publication number: CN 209519137U) proposes a mask disinfection scheme, the scheme adopts anion technology to disinfect and sterilize, the utility model patent (publication number: CN 206576482U) proposes a mask disinfection technical scheme adopting ultraviolet disinfection and sterilization, both the two schemes lack the technical means for solving the problem of mask drying, and mask disinfectors sold on the internet like the above technical scheme in the current Jingdong, Tianmao, Taobao and the like basically have the same defects, so that the mask disinfector has a further improved place.
Some proposals have been made to improve the cyclic utilization rate of the mask by using medical alcohol spraying, high-temperature water boiling, microwave oven heating and other sterilization methods, which may lead to serious deformation of the disposable mask, damage to the physical structure of the filter cotton inside the mask, and decrease the filtering and adsorbing capacity of the mask to germs, and therefore, this method is not preferable.

The nano mask disinfection and sterilization liquid which is formed according to the proportion is tested by a microorganism test center in Guangdong province and an analysis test center of Guangzhou chemical research institute in Chinese academy of sciences, the sterilization rates of staphylococcus aureus and aspergillus niger viruses are respectively more than 99 percent and 98 percent, and the nano mask disinfection and sterilization liquid is non-toxic and free of skin irritation in safety.
Test conclusion table:
tests show that in the disinfection and drying process, the ultraviolet disinfection device 3 can disinfect the mouth mask by irradiation for 20-30 times
The temperature in the mask disinfection and drying device is kept between 40 and 50 ℃ in minutes, so that the best disinfection effect can be achieved, adverse effects on fibers in the mask and mask deformation caused by overhigh temperature can be prevented, and the best performance of the mask which is reused is ensured.
The results of multiple tests show that after the disinfection and drying treatment, one disposable protective mask which is used by the user can be reused for 5 to 8 times or even more, and the performance of the disposable protective mask is not consistent with that of a new mask. The mask which is seriously deformed and damaged and cannot be reused is disinfected and dried before being discarded, so that the chances of pathogen reproduction and retransmission are completely eliminated.
In a very period, the mask is disinfected and reused, waste is refused, and disinfection treatment is carried out before discarding, so that pollution is prevented, and virus spreading is prevented.
