Problems solved by technology

[0003] The "concepts" of the above respirators are all unsatisfactory, and their common shortcomings are: there is a stuffy problem when breathing, and it is not practical
Existing respirators still have the problem that dustproof and poisonous can not be carried out at the same time, so they are not suitable for the environment where dust and poisonous gas exist at the same time and are not convenient for long-term use.
At present, there is no portable breathing respirator at home and abroad that is not stuffy, dust-proof and anti-virus at the same time, and is convenient for long-term use.
