Abstract

A protecting (or welding) face shield without generation of fog features that it has an internal mouth-nose mask and the air outlets in the front of mouth-nose mask and under it for exhausting the CO2 expirated by the mask.

Description

Technical field [0001] The invention belongs to the class of protective masks, and relates to a protective mask and a welding mask that are not easy to generate mist. Background technique [0002] Existing protective masks and welding masks do not have oral and nasal masks. Therefore, the carbon dioxide exhaled by the human body can easily produce fog on the transparent mask sheet or goggles in front of the line of sight, which affects vision and even obscures the line of sight, and causes the concentration of carbon dioxide in the mask. Increased effects on breathing and health. Summary of the invention [0003] In view of the above problems, the object of the present invention is to provide a protective mask that is not prone to fogging on a transparent mask sheet and a welding mask that is not prone to fogging on the goggles. [0004] A protective mask that is not easy to generate mist, including a transparent mask, is characterized in that: an oronasal mask is provided on th...
