[0002] Occupational diseases refer to diseases caused by workers of enterprises, institutions and individual economic organizations who are exposed to dust, radioactive substances and other toxic and harmful substances during their occupational activities. In production labor, workers are exposed to toxic chemicals used or produced in production, dust mist, abnormal meteorological conditions, high and low air pressure, noise, vibration, microwaves, X-rays, gamma rays, bacteria, mold; long-term forced body position operation, continuous pressure on local tissues and organs, etc., which can all cause occupational diseases.

[0003] Existing metal dust protection devices are mostly composed of independent protective covers. When the metal dust protection covers are in use, due to their own insufficient filtering effect, dust is easily inhaled into the body by workers, causing physical damage. After wearing for a long time, the protective covers will accumulate a large amount of hot steam, which is easy to feel stuffy and airtight, reducing the work efficiency of workers. The mask will hinder the exchange of oxygen and carbon dioxide. Especially when the protective effect of the mask is better, the inhaled carbon dioxide may increase, reducing breathing efficiency. Therefore, the present application designs a metal dust occupational disease protection device to solve the above problems. Utility Model Content
