Efficient multifunctional protective mask for avoiding pneumoconiosis and application thereof

Abstract

The invention relates to an efficient multifunctional protective mask for avoiding pneumoconiosis and an application thereof. The efficient multifunctional protective mask comprises a mask body provided with a goggle, an exhaust fan, a power supply and a handle, and is characterized in that a smoke and gas exhausting device for exhausting mixed miscellaneous smokes entering the mask body is arranged in a hole of the mask body corresponding to a nose part; the smoke and gas exhausting device comprises a self-locking inner sleeve and a self locking outer sleeve which are separately arranged on the inner side and the outer side of the hole in the mask body and are combined together to form an air discharging pipeline fixed on the mask body, and the smoke and gas exhausting device cooperates with a negative pressure generated by the operation of the exhaust fan on the mask body to exhaust smokes and exhaled gases in the mask body; the inner cavity of the smoke and gas exhausting device is a spiral ventilation structure. Obviously, the efficient multifunctional protective mask provided by the invention fully and exhaustively gives play to blowing and adsorbing effects of front and back surfaces of the exhaust fan, and the three gears of wind speeds can efficiently exhaust smokes and gases and shield light at the same time, so that the health environment of practitioners is protected, and as a protective hat for a welder, a flame gas cutting worker, a paint sprayer and a polisher, the efficient multifunctional protective mask has very good social and economic benefits, and gets extensive promotion and application.

Description

technical field [0001] The invention belongs to a labor protection device, in particular to a high-efficiency multifunctional protective mask for eliminating pneumoconiosis in welders and other types of work and an application thereof. Background technique [0002] Many jobs often require labor protection for practitioners. For example, electric welders need to protect against health hazards such as smoke and strong light produced by melting electrodes. Welders are an important type of work in the manufacturing industry. Due to their harsh working environment, welding produces A large amount of smog, dust and harmful gas, pneumoconiosis occurs to many practitioners every year. At present, although there are protective caps that can protect against strong light and smoke, the function of the exhaust fan cannot be fully utilized. Often, smoke and dust enter from the periphery of the mask, which not only causes pollution, but also interferes with the eyes so that the welding su...

Problems solved by technology

At present, although there are protective caps that can protect against strong light and smoke, the function of the exhaust fan cannot be fully utilized. Often, smoke and dust enter from the periphery of the mask, which not only causes pollution, but also interferes with the eyes so that the welding surface cannot be seen clearly and affects welding. Quality; Existing technology is only limited to exhaust fan blowing to welding surface in addition, does not consider that the wind force that welding surface
