Abstract

本发明公开了一种具备过滤与净化功能的呼吸面具,由面罩和滤毒罐组成;面罩包括罩体、眼窗、通话器、呼吸活门和紧固件,其特征在于,还包括由两个或两个以上相互串联组合的呼气阀片组成的双层呼气阀或多层呼气阀;所述呼气阀片之间以及呼气阀片与罩体之间设有格栅,所述面罩本体的底部设有进气口,所述的进气口通过导气管连接有滤毒罐,所述滤毒罐包括前后叠加的第一吸附部件、催化部件和第二吸附部件。该催化剂对建筑物内空气中苯、甲苯、二甲苯、乙苯、苯乙烯、甲醛、乙醛、丙烯醛的去除达到了0.05毫克/立方米以下,同时显著降低了循环气中的微生物含量。
The invention discloses a breathing mask with a filter and purification function. The breathing mask comprises a mask and a canister; the mask comprises a mask body, an eye window, an interphone, a breathing flygate and a fastening component. The breathing mask is characterized by further comprising a double-layer breathing valve and a multi-layer breathing valve which is formed by connecting two or more breathing valve plates in series; a grating is arranged between every two adjacent breathing valve plates as well as between one breathing valve plate and the mask body; an air inlet is formed in the bottom part of the mask body; the air inlet is connected with the canister through an air guide tube; and the canister comprises a first adsorption component, a catalysis component and a second adsorption component which are superposed from front to back. By adopting a catalyst, the content of benzene, methylbenzene, dimethylbenzene, ethylbenzene, styrene, formaldehyde, acetaldehyde and acrolein in the air in a building can be reduced to be smaller than 0.05 mg/m<3>, and meanwhile, the content of microorganisms in circulation air is obviously reduced.
