Description

Protective mask for oil field underground operation Technical Field The utility model relates to the technical field of protective masks, in particular to an oilfield downhole operation protective mask. Background In oilfield downhole operations, workers often face complex environmental conditions including toxic and harmful gases, dust, high temperature and high humidity, and other adverse factors, which pose a serious threat to human health and safety. In order to protect the respiratory system and the face of the operator from external contaminants, protective masks are indispensable protective equipment. However, the existing protective masks still have a number of disadvantages in practical applications. For example, the traditional mask has poor sealing performance, which easily causes external pollutants to enter the mask to influence the protection effect, and meanwhile, the breathing device has a complex structure, the filter element is inconvenient to replace, and the requirement of rapid maintenance is difficult to meet.
