Novel zero-smoke mask

Abstract

The invention relates to a novel zero-smoke mask. The mask comprises a mask body, a front mask body with one end open and the other end closed and an air inlet hose, wherein a front end of the mask body is tightly connected with the open end of the front mask body, so internal containing cavities are communicated with each other, and an edge of the rear end of the mask body is perfectly attached to the face of a human body; an inner containing cavity of the front cover body is divided into an air inlet cavity and an air outlet cavity which are distributed up and down through a partition plate,one-way air inlet short pipes are arranged on the cover walls on the two sides of the air inlet cavity respectively and connected with airtight connectors arranged on the outer sides of the corresponding cover walls, and the airtight connectors are communicated with air inlet hoses respectively; the two air inlet hoses are connected with an air supply pipe of air supply equipment through a three-way airtight joint; a connecting plate is arranged on the connecting face of the front portion of the mask body and the air outlet cavity of the front mask body, two air outlet holes are formed in theconnecting plate, and a shutter type exhaust port is formed in the mask wall of the lower portion of the corresponding air outlet cavity. The mask is simple in structure and convenient to wear; smokedust and dust can be completely isolated so that the health of workers is guaranteed.

Description

technical field [0001] The invention belongs to the technical field of protective equipment, and in particular relates to a novel zero-smoke mask. Background technique [0002] At present, in some production and processing plants, the generation of harmful gas, dust and droplets is unavoidable, which affects the health of production personnel. However, most of the existing masks are made of cotton cloth, which cannot achieve the purpose of isolating dust and filtering completely. During use, the face will have a sense of stuffiness and swelling, which will endanger the body, and it will not be able to achieve the purpose of filtering dust and purifying the air. Security risks. Now many masks cannot achieve the purpose of completely cutting off smoke and dust. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the invention provides a novel zero-smoke mask. [0004] In order to achieve the above object, the technical scheme of the present inv...
