Protective mask

Abstract

The invention discloses a protective mask. The protective mask structurally comprises a mask body, a headband, a face screen, a mouth and nose mask, a first shell, a respirator box, filtering cotton,a filtering cotton cover, a blowing device and a lighting device, the front end of the headband and the rear end of the mask body are sewn to each other, and the rear end of the face screen is horizontally bonded to the front end of the mask body. The protective mask provides the design of a lighting device, the problem that the surrounding environment is too dim and inconvenient to detect is solved, a lighting switch is pressed, light is emitted by a led light, the light is emitted through the protective cover, a second lithium battery in a second battery box can supply power to the led light, when the second lithium battery needs to be replaced, a second battery cover can be opened, the second lithium battery is taken out, and the beneficial effects that effective illumination in a dimlyenvironment is achieved and detection is convenient are achieved.

Description

technical field [0001] The invention relates to the technical field of protective masks, in particular to a protective mask. Background technique [0002] Protective masks are appliances used to protect the face and neck from flying metal debris, harmful gases, liquid splashes, metal and high-temperature solvent splashes, mainly including welding masks, anti-shock masks, anti-radiation masks, anti- With the rapid development of industrial technology, the new type of protective mask for pipeline inspection has also been improved technically. However, in the existing technology, during the pipeline inspection process, the air circulation is not smooth, toxic gas is accumulated, and the human body is damaged. The chance of inhaling toxic gas increases, and the surrounding environment is too dark to detect. Contents of the invention [0003] (1) Technical problems to be solved [0004] In order to overcome the deficiencies of the existing technology, a protective mask is pro...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the deficiencies of the existing technology, a protective mask is proposed, which solves the problem of poor air circulation, accumulation of toxic gas, and increased chance of human body inhaling toxic gas during the pipeline detection process, and the surrounding environment is too dark to carry out detection. problem, to achieve the beneficial effect of effectively blowing away the accumulated toxic gas, reducing the possibility of inhalation, and effectively illuminating in a dark environment for easy detection
