Background technology
Power supply air system can provide pure air to the protective respirator such as breathing mask, face shield and maintain the inner certain malleation value of protective articles.Power supply air system is widely used in the respiratory protection of staff under contaminated air environment, and it, by by sending into the mask of user, face shield or the helmet etc. after contaminated air purification, provides high-grade security protection to user.Usual described dusty gas comprises particulate aerosol, bioaerosol, toxic gas or steam etc., and these all carry out filtering purification by being equipped with the air cleaner on power supply air system air inlet.Typical power supply air system generally includes one and can provide the blower fan of certain pressure, provides the battery of power or power supply, the one or more filter being positioned at supply air system air inlet and balancing boom device composition to blower fan.Blower fan and filter can be directly installed on breathing protecting mask, or are independently arranged on a shell, are connected with mask by flexible pipe.
Power supply air system initiatively can carry pure air in the protective articles such as mask, head-shield, thus make the respiratory resistance that wearer brings without the need to overcoming filter etc., and certain malleation can be provided to inside such as masks, and effectively avoid general mask problem, the problem includes: dead space problem, thus significantly improve the security of wearing and comfortableness.The research such as Marc shows, under equal conditions, power powered air-purifying formula mask protection factor is than self-absorbing filtering type mask height 10-50 doubly left and right.Andrea etc. investigate the wearer of display 85% think wear power blow the full visual field mask time work capacity stronger than wearing general mask.
United States Patent (USP) 6435184 describes a kind of power air-supply breathing protecting mask, and main feature is that supply air system and mask are combined closely, and respectively has a cuplike cavity in mask side, and built-in two pieces of rechargeable batteries, have longer continuous working period.
Patent W02009/067583 describes a kind of modular power supply air system and breathing protecting mask, be connected with patent filter tight by high-performance centrifugal blower, battery is installed separately, is connected with blower fan with helix, a filter can be installed, also multiple filter can be installed.The main feature of this invention is integral sealing waterproof, and filter mounting interface can automatic airtight, therefore can in use change.
Although above-mentioned domestic and international patent all possesses the basic function of power supply air system, but the electric quantity monitoring lacked power supply air system itself and abnormal alarm function, supply air system overall construction design is too complicated simultaneously, is unfavorable for light carrying, and adds and uses burden.
