Zusammenfassung:The invention relates to the technical field of breathers, specifically to a micro-positive-pressure self-inhalation filter type escape breather. The escape breather comprises a hood and a mask; and the mask is provided at the front end of the hood. The escape breather is characterized in that a canister is provided on the mask; a smoke filter layer and an activated carbon poison filter layer areprovided in the canister; a fan is provided at the back end of the canister, and provides micro-positive-pressure wind power; a transparent window is provided at the front end of the hood above the mask; and an exhalation valve is provided under the mask, and is disposed in the lower portion of the hood. The escape breather has the advantages that the canister has the activated carbon poison filter layer and the smoke filter layer to achieve the effect of dual filtration, and the fan can provide the micro-positive-pressure wind power to help people who is inconvenient to breathe to inhale. 本发明涉及呼吸器技术领域,具体来说是一种微正压自吸过滤式
