Abstract

The invention discloses a breathing mask with filtering and purifying functions. The breathing mask comprises a face guard and a canister. The face guard comprises a guard body, eye windows, an interphone, a breathing valve and a fastener. The breathing mask is characterized by further comprising a double-layer exhalation valve or a multi-layer exhalation valve, and the double-layer exhalation valve or the multi-layer exhalation valve is composed of two or more exhalation valve blocks which are connected and combined in series; grids are arranged between the exhalation valve blocks as well as between the exhalation valve blocks and the guard body; an air inlet is formed in the bottom of the guard body; the air inlet is connected with the canister through an air guiding pipe; the canister comprises a first adsorption assembly, a catalyze assembly and a second adsorption assembly which are stacked in the front-back direction. By means of catalysts, benzene, methylbenzene, xylene, ethylbenzene, styrene, formaldehyde, acetaldehyde and acrolein in the air in a building are removed till the concentration is below 0.01 milligram/m<3>, and meanwhile the content of microorganisms in recycled air is remarkably reduced.

Description

technical field [0001] The invention relates to the technical field of air purification, in particular to a breathing mask with filtering and purification functions. Background technique [0002] As personal protective equipment, gas masks are used to provide effective protection for personnel's respiratory organs, eyes and facial skin. The mask is composed of a mask, an airway and a canister. The mask can be directly connected to the canister or the canister, which is called a direct connection; or the airway is connected to the canister and the canister, which is called a catheter. Mode. Gas masks can choose various types of canisters according to the protection requirements, and are used in chemical, warehouse, scientific research, and various toxic and harmful working environments. [0003] A common gas mask consists of a face shield and a canister (or filter element). The mask includes parts such as a cover body, an eye window, a communicator, a breathing valve, and ...
