Problems solved by technology
Another problem that needs to be explained is: if someone has infectious germs in his mouth, the exhaust gas in the inner cavity of the mask will be discharged directly through the exhaust valve, and the germs will spread around and infect each other.
[0007] All in all, so far, there is no ideal mask on the market that can achieve easy inhalation and discharge, high exhaust gas replacement rate, and comfortable wearing, let alone an anti-epidemic mask that can isolate germs on this basis

The invention discloses a micro lip-attached epidemic prevention mask. The epidemic prevention mask comprises a mask belt, a lip-attached edge, a waste gas guide pipe, mask filter cloth and an adjusting screw, the lip-attached edge is formed at one end of the waste gas guide pipe, the other end of the waste gas guide pipe is fixed to the mask filter cloth through the adjusting screw and is externally provided with a waste gas exhaust outlet, and the epidemic prevention filter cloth is arranged at the waste gas exhaust outlet. The contradictions that the volume of the cavity in front of the mouth is small, air filtering is not smooth, the volume of the cavity in front of the mouth is large, and the waste gas replacement rate is low are well solved, and the ideal effects of easy breathing, complete waste gas replacement and excellent epidemic prevention effect are achieved.
Description
technical field [0001] The invention relates to the technical field of masks, in particular to a micro-adhesive lip epidemic prevention mask provided with an anti-epidemic filter cloth on an exhaust gas outlet. Background technique [0002] In view of the common problems of epidemic prevention masks and dust masks currently on the market that the effective filtration area is small, the ventilation is not smooth, the cavity in front of the mouth is large, the exhaust gas replacement rate is extremely low, and the wearing is uncomfortable. }’s patent, a relatively comprehensive solution to the problem is proposed accordingly. However, there is still a problem not solved in this patent: the exhaust gas exhaled by people from the mouth is directly discharged outside the mask filter cloth, if there are infectious germs in people's mouths, they will spread around and cause mutual infection. If I want to clearly explain the ideal effect of the new design scheme with anti-epidemic f...
