Problems solved by technology

[0003] When using a gas mask to enter the fire site, there is too much dust inside the fire site, causing a large amount of dust to enter the inside of the filter element, which is easy to block the filter element, and the filter element is fixed inside the gas mask, making it difficult to remove and clean the filter element, which is inconvenient for people to use next time

Abstract

The invention relates to the field of fire control, in particular to a gas mask for fire control. The gas mask comprises a mask, fixing mechanisms, an installation mechanism, connecting mechanisms, compressing mechanisms, a filtering mechanism, a storage groove and an exhaust mechanism; one end of the mask is in threaded connection with the installation mechanism, and the interior of the installation mechanism is slidably connected to the compressing mechanisms and the filtering mechanism; the compressing mechanisms abut against the filtering mechanism; when the gas mask is used in a fire scene, the installation mechanism is rotated, so that the installation mechanism is opened; the installation mechanism is slid to drive the compressing mechanisms to slide in the installation mechanism, so that the compressing mechanisms are separated from the filtering mechanism, thereby facilitating people to slip off the filtering mechanism from the installation mechanism; thus, people can replacethe filtering mechanism conveniently; the connection position between the mask and the installation mechanism is provided with the storage groove fit with a nose, and filtered and disinfected air enters the storage groove; the air that people exhale moves downwards to come into contact with the exhaust mechanism at the bottom end of the mask, so that the exhaust mechanism is pushed to move, and the exhaust mechanism is opened for discharging the exhaled air.

Description

technical field [0001] The invention relates to the field of firefighting, in particular to a gas mask for firefighting. Background technique [0002] A gas mask is a personal special labor protection product, and it is also an individual protective product. It is worn on the head to protect people's respiratory organs, eyes and face, and is a personal protective equipment to prevent poisonous gases, dust, bacteria, toxic and harmful gases or steam and other toxic substances. . 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. Gas masks can be divided into full-face masks and half-masks in terms of shape, and full-face masks are divided into positive pressure and negative pressu...
