[0022] A further feature of this invention is that the mask contains a plurality of filter plates, and the filter plates have a plurality of air passage holes.

[0023] By adopting the above technical solution, the addition of the filter plate can prevent insects or dust from entering the cylinder. At the same time, if the user sneezes while wearing the mask, foreign objects can be effectively blocked on the side of the mask away from the cylinder.

[0024] A further feature of this invention is that two filter plates are provided, which are spaced apart inside the mask, and the air passages on the two filter plates are staggered.

[0025] By adopting the above technical solutions, the filter plate's ability to block foreign objects can be further improved.

[0026] In summary, this utility model has the following beneficial effects:

[0027] The device features an exhaust port and one-way exhaust valve located on the end face of the cover away from the cylinder, with the extraction pipe integrated into the side wall of the cover. This layout allows users to observe the operation of the one-way exhaust valve in real time when using the anti-suffocation device for self-rescue, facilitating timely removal of obstructions near the exhaust port. Furthermore, the exposed one-way exhaust valve is easier to replace when damaged.
