Air respirator

Abstract

The invention relates to an air respirator. The air respirator includes a respirator body and a breathing mask, the breathing mask is positioned on the inner side of the respirator body, at least theparts, corresponding to the eyes, of the respirator body are hollow, and an air inlet and an air outlet are formed in the respirator body; a nonreversible air sucking hole is formed in the breathing mask and is opposite to the air inlet, an exhaling opening is formed in the breathing mask and is opposite to the air outlet, soft sealing rubber is arranged on the brims of the respirator body and thebreathing mask separately, and the breathing mask separates the interior of the respirator body into an outer breathing chamber and an inner breathing chamber. During inhaling, the air sucking hole is opened, air entering the outer breathing chamber from the air inlet enters the inner breathing chamber from the air sucking hole; during exhaling, the air sucking hole is sealed, air in the inner breathing chamber is exhausted from the exhaling opening and the air outlet. By means of the air respirator, breathing air flow is separated, and a technical effect of effectively removing mist is achieved.

Description

technical field [0001] The invention relates to an air respirator, in particular to a separate breathing mask. Background technique [0002] In the ironmaking industry, since the blast furnace body often has gas leakage, it is necessary to wear an air respirator when working in the blast furnace body. Therefore, in the ironmaking industry, air respirators are not only used as protective tools for emergency rescue work, but also as necessary protective equipment for daily work. [0003] Existing air respirators need to isolate the external toxic and harmful gases from entering the mask, and the mask should be closely attached to the wearer's face, so people with visual impairments cannot wear it and use it, which is inconvenient for wearers of glasses; in addition, the user's voice It also cannot be clearly conveyed to others, resulting in the inability to communicate smoothly among personnel. It is inconvenient to use, greatly reduces work efficiency, and is also unfavorab...
