Under the premise that the connector sleeve and the gas mask fit together, the threaded sleeve can be made in various specifications to be compatible with the corresponding size of the filter canister. When using different filter canisters, there is no need to change the gas mask. Only the connector needs to be changed to achieve the switch, which greatly increases the adaptability and makes the application quick.

[0013] A rubber sealing ring is fitted inside the annular groove. The rubber sealing ring can fit and seal with the installation position of the gas mask, which facilitates assembly and use and maintains a tight connection.

[0014] The one-way filter membrane ensures that air can pass through the filter canister and the one-way filter membrane when inhaling, and is exhaled through the exhaust valve in the gas mask when exhaling, thus forming a stable breathing direction. In addition, the ring beam and the cross section of the installation net are both inverted triangular structures, which facilitates air permeability. Attached Figure Description
