Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1-4, an embodiment of the present invention is shown: in order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a respiratory protection device who contains active carbon, including the cover body 1, the both sides of cover body 1 are provided with ear fixed orifices 2, one side on cover body 1 top is provided with nose bridge fixed strip 3, cover body 1 top is provided with elastic support ring 4, the inboard of elastic support ring 4 is provided with air filter 5, one side that air filter 5 is close to elastic support ring 4 is provided with first cover body 51, one side that air filter 5 is close to first cover body 51 is provided with first filter layer 52, one side that air filter 5 is close to first filter layer 52 is provided with second filter layer 53, one side that air filter 5 is close to second filter layer 53 is provided with second cover body 54, the both sides of first filter layer 52 and second filter layer 53 are provided with and
