Abstract

The invention discloses an inhalation and exhalation filter type mask. A respiration valve body is arranged at the inner side of a mask body. The respiration valve body is provided with air inlets, air outlets and respiration openings corresponding to nares of a user. The mask body sequentially comprises a plurality of composite filter layers and a moisture absorption layer from exterior to interior. The edge of the mask body is sealed and fixed. A welding mark A is arranged in the middle of the mask body. The air outlets communicate with the mask body through air tubes A. The connections of the air tubes A and the mask body are located at the same side of the welding mark A. The connecting ends of the mask body and the air tubes A are located at the outer side of the moisture absorption layers. According to the structure of the inhalation and exhalation filter type mask, a user who wears and uses the mask can easily and conveniently exhale air out of the mask, and the respiration comfort of the user wearing the mask is improved, so that the phenomenon that exhaled gas remains and is gathered between contact surfaces of the face of the user and the mask, the user feels discomfortable, and eczema is caused is avoided.

Description

technical field [0001] The invention relates to the technical field of a filtering mask, in particular to an inhaling and exhaling filtering mask.
