Abstract

The invention relates to a portable protective mask. The portable protective mask comprises a body and a filter part rotationally arranged on the body, wherein the body is provided with a visual area and a breathing hole used for breathing; the filter part comprises a connection part rotationally arranged on the body, and a plurality of function parts arranged on the connection part, the plurality of function parts are arranged at intervals, each of the function parts rotates with the connection part, one of the function parts covers the breathing hole and communicates with the breathing hole, and a plurality of filter layers are arranged in each of the function parts at intervals. According to said portable protective mask, due to the plurality of function parts, after filtering capacity of one of the function parts is used up, another function part can be rotationally used for filtering, thus the service time of the portable protective mask is prolonged, and the portable protective mask is higher in reliability; because the plurality of function parts are rotationally arranged on the body, the portable protective mask is simple to operate, and convenient for users to use; in addition; the visual area covers eyes, and damages to eyes can be further avoided.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a portable gas mask. Background technique [0002] Gas mask is a kind of protective equipment, which is used to protect human respiratory organs, eyes and face, and prevent personal protective equipment from toxic substances such as poisonous gas, dust, bacteria, poisonous and harmful gases or steam. Gas masks are widely used in petroleum, chemical industry, mining, metallurgy, military, fire protection, emergency rescue, health and epidemic prevention, technology and environmental protection, machinery manufacturing and other fields, and can also play an important role in cities with severe smog and photochemical smog. Respiratory protection. [0003] However, the current gas masks are used for a short period of time and have poor reliability. Contents of the invention [0004] Based on this, it is necessary to provide a portable gas mask with longer service time, better reliability a...
